In the early years of reform and opening up, Dapeng put forward suggestions to the party committees of the regiment and division to rationalize and transform the brick factory. In 1981, the 450 large-scale brick making machine and three-stage reducer designed by the Corps brick factory machinery were renewed.

After returning to the city in 1982, he designed and processed batching machines and various equipment for the railway brick factory, which was a pioneering achievement 14 years after he left the Fularji brick factory. In those two years, Dapeng was able to change two brick factories, which was not only a great sacrifice for individuals and the whole family in that era, but also a major contribution to the reform and opening up.

Before returning to the city from the Corps brick factory, Hua Ying went to find the old lady Dongshan, she not only went to visit Liu Xueyou and the Old Summer Palace, but also invited the old lady Dongshan to her home to say goodbye. The 77-year-old lady only said a few words of advice: "Huaying, your family will definitely be reunited in the city, and Xiao Zhang will not abandon your old man in this life, but it is difficult for him to settle down? Tell him that the date of going through the procedures for returning to the city is the date of the household registration." ”

Hua Ying came back and mentioned to Dapeng, but after many studies, I don't know what he meant? The date of the procedure for returning to the city was May 19, 1982, what does the problem illustrate with only seven figures? According to legend, Sun Yat-sen's will mentioned to Chiang Kai-shek: You will not leave Sichuan on land, and you will not leave the bay if you flee. Buddhism mentions the word 8341 to **, which indeed verifies the conclusion. He himself is a poor person, how can he compare numbers with the great man? Dapeng also returned to the city with his family in doubt, and he didn't know what the consequences would be?

Song Shichang was a retired worker hired by Duan, and he was a technical authority at the railway brick factory, and when the shutdown stopped in the fall, he brought Dapeng to the office, and the factory director Xu and Secretary Tong asked for the machine to be updated. Dapeng explained that in order to improve the output, the quality cannot be ignored, first of all, the new batching machine should cancel the manual cart batching, increase the mixer, crusher, conveyor and roller cage screen, and strive to save energy without coal burning bricks. However, there are problems of transformer capacity increase, bulldozer problem, shovel bucket problem and induced draft fan problem under the kiln, with an investment of about 40,000 yuan. It was unanimously approved by the party branch and decided to withdraw the bonus at 5% for those who contributed to the renewal of equipment.

Director Xu is responsible for the purchase of bulldozers, shovel buckets and transformers, and Song Shichang and Dapeng are mainly responsible for the design and processing of crushers, conveyors, roller cage screens, batching machines and mixers. First of all, it is necessary to complete a large grinder to prepare for the winter powder ash ash, and in order to achieve the goal of burning bricks without coal, four thousand cubic meters of carbon ash must be completed. Therefore, it is necessary to set up a transportation team, and the car transports the bricks to the urban area, and after unloading the bricks, the bricks are loaded from the boiler room of the four railway bureaus and then loaded with carbon slag and transported back to the brick factory. Since the batching machine and the pulverizer are bulldozer pushers, the rails, sleepers, and steel plates are urgently needed, and the support of the real estate section is requested.

Dapeng and Master Song came to Weidong factory, a workshop Director Li, Yin engineer looked at the drawings, mixer, large crusher, cage screen, two conveyors and batching machine spare parts total 7,000 yuan, signed by the two sides of the agreement, by the Weidong factory according to the requirements of the processing began.

In order to save money, Dapeng wanted to build a batching machine that combined soil and foreign materials, and first let the Weidong factory process a large 50 cm diameter eccentric bearing, and process five shafts and bearing housings. Nearly 60 meters of old axles were required from the waste pile of Weidong Factory, and more than 200 rollers and sheaves were processed with brick factory lathes and vertical drills. It is also necessary to return to the Corps brick factory and the spare parts of the Jiulian pulling batching machine, and use the old chain rail plates of the two tractors as the transportation tools for transporting the ash and soil.

There are two female deputy factory directors in the brick factory, one surnamed Lin is a model worker of Duanhe Railway Bureau, she is in charge of worker production, and the other surnamed Liu is an electrical welder who is domineering. Two pits should be completed before winter, one is a large pit three meters square and two and a half meters deep by the crusher. The other is a large pit that is 12 meters long, 5 meters wide and 3 meters deep for the batching machine. However, Deputy Factory Director Liu insisted that the workers only dig four meters wide, and I don't know why she was disgusted with the mechanical renewal project, why did she resist? It seems that the brick factory is her family's orders, and there is serious bureaucracy.

After the installation of the crusher, conveyor, and roller cage screen, Director Xu bought a bulldozer and a shovel bucket. The bulldozer can push the slag ash, the shovel bucket also begins to adjust the soil, and the fitter room workers work hard to process the batcher stick. Dapeng bought a house near the brick factory in order to bring his parents-in-law to reunite.

Factory Director Xu and driver Xiao Li drove to the XPCC brick factory, and they first visited the brick machine designed by Dapeng. Secretary Zhuo introduced: "Despite the delay of half a month of production, 7.1 million red bricks were completed, creating the highest record in history. Although Zhang Dapeng returned to the city and left, Head Wang still proposed a commendation. Director Zhuo had a banquet in the canteen, and all cadres and fitter Li Zhongyi attended the congratulations.

Dapeng proposed during the banquet: "Director Xu brought you black steel powder, another is called cemented carbide steel, which is specially used for the hardening of drilling cutter heads and gears, and we use it to flame spray on the reamer, because of its hardness, the production of 100 days can change the reamer once, changing the cumbersomeness of changing the main reamer once every two days." The operation method is to use the welding helmet of the headband, one hand to hold the welding handle, the other hand to hold the iron sheet rolled black steel powder, with the welding pool high temperature to melt the black steel powder on the blade. But we need the help of four six-star wheels and helical gears. ”

Secretary Zhuo not only agreed, but also asked the workers to load the truck, and each of them gave a piece of pork before leaving. Dapeng brought the car to the third camp, and the company commander Huang not only asked the workers to install the old chain rail plates eliminated by the three tractors, but also helped Dapeng's parents-in-law move furniture and load the car, so that the two elderly people returned to the city with the car to reunite with their families.

The batching machine is the key equipment of the brick factory, which is composed of three tractor chain plates, each chain plate weighs 27 kilograms, nearly 200 chain plates are two tons, plus the chain rail pin, roller, 1.1 meters long 30 cm wide and 1 cm thick link iron plate, the iron plate has a groove wheel in the middle, stuck in the rack of the rail operation, only the box weight is more than 5000 pounds, like an 8 meter long heavy tank suspended in the air, then there must be a railway steel frame structure shelf. First of all, it is necessary to lay a reinforced concrete base, and 30 channel steel and 20 rails are 8 meters long and placed in the base layer. In order to withstand the weight impact of the bulldozer, it is necessary to weld the channel steel and the rail, the rail is a sleeper, the sleeper is an iron plate, and the iron box of the batching machine is 8 meters long, 80cm wide and 1 meter deep, and it is equipped with a ratio gate to control ash.

According to the principle of the conveying machine of the batching machine, the first thing is to cut the side of the chain rail plate, draw a line, and cut a screw hole that can penetrate 10 cm with gas welding. The 1.1-meter-long 30-centimeter-wide iron plate not only has to cut the eyes at both ends, but also welds two angles with eyes in the middle of the iron plate, and the space should be 6 cm. On the side of the iron plate, the curved buckle head should be slapped with a sledgehammer, so as to run to the end to avoid dust leakage. The chain rail plate connected at both ends of the iron plate is put on the chain rail pin, and one end of the pin is put on a 6 cm iron roller to run on the angle steel welded on the shelf, and the iron roller at both ends and the middle groove wheel of the iron plate can operate normally at three points and one line.

The power of the batching machine is 13 kilowatts of 8-level motor, 980 revolutions per minute, through the rotation of pulleys and gears, the spindle on the batching machine should be reduced to 90 revolutions, the shaft of 10 cm diameter should be rotated to eight eyes, the 1-inch iron bar is screwed, and the other end is welded with an iron plate named mace, and the iron plate is the blade running at 90 revolutions per minute, which is specially used to cut mud blocks and mix ash. One end of the spindle is an eccentric large bearing, the bearing jacket is welded with a shaft of 6 cm diameter, the other end of the shaft is flattened, it is to drive the helical tooth, due to the large helical gear of 42 teeth, the speed is only more than two turns per minute, the gear is transmitted to the six-star wheel to drive the chain plate forward, every four minutes a side of the ash supply, can produce 6000 billets per hour, and the brick-making host is basically matched.

The iron plate behind the batching chassis is oblique, and the rear two-meter gate is raised by 20 cm to be the capacity of ash, and the upper 80 cm is the capacity of sand, which is completely operated by bulldozers. After the motor is started, the variable speed spindle rotates 90 times, and the eight mace blades crush the mud and ash into the conveyor belt box, and the mixed soil ash enters the first mixer, which is controlled by a water pipe, and the mixing ash of 60 blades is advanced to the conveyor, transmitted to the second mixer, and then passed through the conveyor belt to the main machine with a special person to guard. The big roller in front of the mouth automatically cuts the mud strips, the fast roller passes the mud strips into the blank cutting table, touches the automatic clutch plate, the blank cutter automatically pushes the mud strips into the blank plate, six people change the mud line to pull the plate to the roller frame, the elevator every six slabs fall into the cart, a dedicated person helps pull the cart, the billet is sent to the racking shed, the person with the rack holds the blank with both hands to disperse and dry, cancels the tradition of racking with an iron fork, avoids the drawbacks of two eyes in the middle of each billet, and ensures the output and quality of the product.

However, before production, the 320 thousand volt transformer bought by Xu was twice as large as the original, although it only cost 6,000 yuan, and the capacity increase fee was 200 yuan per thousand volts, and the additional 160 thousand volts was 32,000 yuan. Director Xu was hospitalized with a sudden cerebral thrombosis, he was originally a retired cadre, but now he fell ill for the cause of the brick factory, and Dapeng was moved by his professionalism.

Secretary Tong asked Dapeng to serve as the factory director four times, saying that it was the result of the research of Director Xu and Secretary Song. First: the decline of the hukou is that the temporary workers have not become regular, two: most of the nearly 100 people in the factory are the families and children of the workers are regular workers, and the third: the brick factory has not been convincing for less than a year. However, Dapeng recommended Gai Yingjie as the factory director, he returned to the city earlier than Dapeng, and now the real estate section has turned a car into a regular one, and Dapeng proposed to assist him in his work.

Whenever the workers were on vacation, Dapeng did not want paid weldments in the brick factory. The second uncle-in-law of the South Bureau House came to visit him, especially the rich uncle who watched Dapeng grow up, and often came to the brick factory to visit Dapeng's work and family life, he was angry to Duan Li and scolded: "I only give a salary of more than one yuan a day, skillfully use people to engage in machines, and the eyes of the officials are blind?"

Secretary Song Changli came to organize the opening ceremony, he called Dapeng to the front of the venue, personally presented two trophies, firecrackers went off outside, and people went to observe the operation of the new machine. Because the transformer was not replaced, the method of starting the motor one by one was adopted, the starting current of each motor was infinite, and then the next motor was started after it was stable, and the empty car was no problem, the bulldozer was loaded and the heavy car was running, and the electrician was sealed and tripped on the switchboard. Just when the machine was running normally, people were celebrating, and the batching machine suddenly stopped running, what happened?

Originally, the batching machine was five meters wide pit, when Liu deputy director had to dig four meters wide, the gear installation could not be driven with a sledgehammer, due to the impact of the heavy car, resulting in a gear falling off, after re-installing, Dapeng let the electric welding reinforcement, although this is only a fly in the ointment, but this is completely the consequence of bureaucracy.

When the machine is in normal production, Dapeng proposed to the director of the factory to streamline the administration, first cancel the deputy director Liu, cancel the two workers on the main machine, change the six pull plates to four people, and the fitter room should have three people to watch the machine and maintenance, so as to eliminate the waste of people floating in things. According to the regulations of the brick factory, how much bonus should be given to Dapeng? However, the factory leaders studied raising Dapeng's salary by two levels, and subsidizing an additional 9 dimes a day, except for Master Song Shichang, Dapeng's salary was the highest.

Master Song, Wang Jichun and Dapeng studied the automatic coal loader and automatic brick unloading truck, and invested in the transformation of the equipment of the finished kiln team, replacing the coal and brick production of the small cart, which not only improved the efficiency, but also enhanced the quality of the red bricks.

Due to the transformation of technical machines, the brick factory can achieve millions of bricks without coal, which has alarmed the province, city and dozens of brick factories. For more information on the impact of the deeds, see Chapter 78: Burning bricks saves energy without coal.
