After Zhang Tao returned home, he began to make a machine for drilling the ground, and yesterday he had almost finished the machine, put the workpiece on the machine tool and clamped it, and pulled the door of the CNC machine tool. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info pressed a few buttons on the machine computer, set the program, press the confirmation part, and the machine will process by itself.

After ten minutes, the workpiece is machined and the surface roughness is very good, which can be used as a mirror. I put on leather gloves and took out the workpiece, touched the surface of the workpiece with the gloves, and the mirror was gone.

Zhang Tao wants to make a pangolin-shaped drill, and when he is drilling, others will only think that it is an animal plowing the ground, and will not suspect anything. Take the processed workpieces to the ground and place them.

Then take the welding machine, put the zero line of the welding machine on the workpiece, and then turn on the welding machine. Clamp the electrode with a clamp, hold the mask in your left hand and the clamp in your right hand to weld the workpiece.

After welding the finished part, wait for the workpiece to cool down for a while, and file the burrs and protrusions with a file. After filing, the pangolin's skeleton is ready, and the heart and claws are mounted. The electric motor, diesel engine, CPU, memory, signal amplifier, and signal transmitter are placed in the pangolin's belly, and then the limbs are connected to wires, and the wires are connected to the drill and wheels.

Some of the processed iron pieces are welded to the shell with an electric welder to be used as pangolin scales. Containers are worn inside the head and tail with diesel fuel. Mounted with screws on the head and tail of the pangolin.

Bring a few cans of paint, and paint the scaly areas and eyes with taupe paint, and the paws of the face and limbs white. Brush the scales with dark red paint.

It is estimated that the paint will take two days to completely dry, and after it is done, the pangolin-type drill really looks like a pangolin from a distance. If you look closer, you have to show your stuffing, but when the time got closer, Zhang Tao had already controlled the drill and ran.

Zhang Tao cut a section of iron rod into several small discus with a lathe, and then put the discus on the milling machine and milled the small discus into gears with a milling cutter. Some other parts of the drill were also machined and kept for later use.

After waiting for the pangolin drills to dry for two days, Zhang Tao went to the city to pass the second subject. I went to the Wujiaohua Building and bought a large number of drill bits for drilling walls and more than a dozen bottles of nitric acid and glycerin. The drill bit is a few yuan a bottle, nitric acid and glycerin are ten yuan a bottle, Zhang Tao bought it in large quantities, and the price was discounted, and it only cost more than 300 yuan in total.

I got on the bus to the bottom of Hengshan Mountain and returned home, and after returning home, I cooked a dish with monkey head and matsutake mushrooms, and cooked some noodles for lunch. I took a nap until one o'clock in the afternoon, and when I got up, I was very energetic, but I was a little dazed, and I walked in the yard for half an hour, and woke up with my head cleared.

Zhang Tao next wanted to make explosives, and when drilling wells, he often encountered very hard rock layers, and he had to need explosives. You can't be sloppy when making explosives, you must have enough mental energy.

Zhang Tao put on the field uniform given to him by his cousin, which was of good quality and had a certain degree of corrosion resistance. Then put on thick leather gloves, put a bottle of nitric acid and a bottle of glycerin on the ground, take a beaker, open the cap of nitric acid and glycerin, pour some glycerin into the beaker first, and then put the cap on the bottle. Pour in some more glycerin and put the lid on as well.

After a short while, some yellowish precipitate appeared in the beaker, and nitroglycerin was made. Zhang Tao poured the remaining liquid in the beaker into another beaker, poured alkali to synthesize the solution into saltiness, and then poured it out.

Pour the yellowish substance from the beaker onto a piece of paper, wrap the nitroglycerin into a small cube with the paper, put it in a large cardboard box, and put the cardboard box in the freezer to freeze.

After more than an hour, Zhang Tao used up all the nitric acid and glycerin and made a small half carton of nitroglycerin. When nitroglycerin is exposed to heat and vibration, it becomes unstable between molecules. There is a possibility of an explosion, so put it in the freezer and freeze it, and then take it out when you use it.

I went to the warehouse and looked at the pangolin-type drill, touched the paint surface with my fingernails, but it didn't get it, and then touched it with my fingers, and the paint was already dry. Put the pangolin drill on the scale and weigh it, there are 100 and 7 catties.

Zhang Tao removed the head and tail of the pangolin driller with a screwdriver, and then packed the parts of the pangolin driller into a large cardboard box, and stuffed foam paper between the parts to prevent the parts from colliding with each other during transportation.

I checked the water and electricity in the house, packed up my clothes and put them in the cardboard box, then took out the cardboard box containing nitroglycerin in the freezer, and used transparent tape to cross and wrap the cardboard box several times, tie a rope to the intersection, and then help the rope to the drone chassis.

The remote-controlled drone slowly rose up, flew higher than the mountain, and then let the drone fly slowly in the direction of the forest farm. Half an hour later, the drone flew into the courtyard of the Lilinchang villa.

Zhang Tao asked the drone to fly the rope next and into the warehouse. Then put everything on the donkey, take a large piece of hair dryer cloth and cover everything, save others from seeing, and protect it from rain and sun.

Remove the filter from the donkey, put the wet gauze on it, and put it back on. I took a few more pieces of gauze and moistened them and kept them for future use. Start the diesel engine, drive the donkey out of the yard, and lock the gate. Heading in the direction of the forest farm, one hour later, it was a little dark, and Zhang Tao arrived at the villa.

After driving the upside-down donkey into the yard, I first went to the bedroom to take out the scissors, cut the transparent tape on the cardboard box, and saw that the nitroglycerin had not yet dissolved. Place in the freezer with a cardboard box and refreeze it.

When I went back to the yard, I reported everything on the donkey, put the pangolin drill and some tools in the barn, and put the clothes in the bedroom. Then go to the boiler room next to the villa and open the boiler sluice and catch some water. Then I took a basket of firewood and coal in the barn and lit the stove in the boiler room, and after a long time, the stove was not lit, and the room was a little damp.

After burning the boiler for a while, I felt that the room was not so damp, so I stopped pouring coal into the boiler. After taking a shower with hot water from the boiler, Zhang Tao had the drone fly to the oil field with a pangolin-type drill.

After arriving at the place, Zhang Tao asked the drone to put the pangolin-type drill on the ground, and then let the drone fly to a big tree next to it to watch around to see if anyone was coming.

Zhang Tao connected the remote control device that controls the pangolin driller to the computer with a data cable, and operated the pangolin drill with a mouse. Turn on the wheels and let the pangolin drill down into the ground next to a pile of rocks.

After drilling down a few meters, he changed the direction and drilled towards the place where the oil company had drilled, although the oil company covered the soil again after exploration, but there were still traces. It is also easier when drilling a second well.
