ps: Thank you 1o4776 brothers and Nanfeng Yu brothers for their tips, thank you!!!!

The second chapter is coming.,Ask for a reward.,Ask for a subscription.,Is there a third chapter in a while?,Brothers!!!

I asked for a collection and a recommendation!!!!!!!!!! ――

Li Jun kicked the stones at his feet and said, "Second brother, I suddenly thought of something now, why didn't I call Director Zheng over just now, I can be regarded as having a witness." This is good, the mine exploded, but only the three of us saw it, and this white-toothed Director Zheng can believe it. Chen Er seemed to have already thought of a countermeasure, and said without worry: "This is all a trivial matter, it's good if it succeeds." ”

Wang Yong listened and asked suspiciously: "Chen Er, could it be that you made two at once, and there is an anti-tank mine in the research room?" Chen Er hurriedly shook his head, this one made him tired enough, if he could really make two in a week, he would be a machine. However, when I was approving the materials, I prepared two copies, and the first one was successfully developed, as the saying goes, practice makes perfect, and it must be much easier to make zuò.

The three of them sat until noon, looked at Chen Ercai and said, "Let's go." If we don't go back, we may only have a cold meal for a while. In order to satisfy your curiosity, the mine was successfully detonated, and you don't want to run away from this second one, you have to go and help me after eating. Li Jun and Wang Yong nodded without hesitation. It's a great learning opportunity, and it would be a fool to miss it.

When the three of them returned to the research room, Murong Wan and Wen Jing had already finished eating, and the three lunch boxes on the table were obviously the three of them. Wang Yong is also used to it during this time, so it is also unceremonious to pick up his lunch box, and he can now be regarded as successfully integrated into Chen Er's small collective. Wen Jing didn't know when she walked out, and when she saw Chen Er and the three of them, she couldn't help but exclaim.

"What's wrong with you, are we collapsing here? Why are they all disgraced. Li Jun, tell me about it quickly. Wen Jing asked worriedly. At this time, Li Juncai remembered that the three of them didn't bother to wash their faces after they came back, and said with a smile: "It's okay, it's okay." This is the research institute underneath, how could there be a collapse, we just went to detonate the mine, and we all became earth monkeys in this explosion. ”

Listening to Li Jun's explanation, Wen Jing also noticed. Although the three of them were covered in dust, they did not have the slightest scar, and it seemed that it was really as they said. Wen Jing didn't say anything more and walked towards Murong Wan's room. She had to tell Murong Wan about this matter, otherwise Murong Wan would definitely be shocked when she saw the three of them like this, and the matter of stepping on the landmine left a lot of shadows on Murong Wan.

After eating, Chen Er took Li Jun and Wang Yong to start the manufacture of the second anti-tank mine, because it was a lesson from the past, and it would be much easier to operate. It also saves a lot of time. Coupled with the three of them, it took one afternoon to complete seventy-seven-eighty-eight, and of course it will take a while before the final assembly is successful. After all, people are human beings after all. There will always be times when you get tired.

In this way, the three of them basically remained inseparable for three days, only during the day, of course. At night, they went back to their rooms and slept to their own nights. Today is finally the stage of the final assembly and the end of the work, and Chen Er must be the last formalities. I saw that he carefully put the detonating device into the thunder body, and then carefully put the lid on it after carefully stabilizing it.

Li Jun and Wang Yong didn't even dare to take a breath on the side, for fear of disturbing Chen Er. Another four or five minutes passed. When Chen Er stood up, the two of them only felt that their backs were a little wet. You can see how nervous they are. It's like eating meat, you may not feel it when you eat it, but if you eat meat at the scene of a slaughter, 99 percent of people will have a hard time swallowing it.

Li Jun and Wang Yong were in such a mood at this time, they saw with their own eyes that the big bag was put in. This is pure intensity, if this big bag is made into bullets, maybe it can be made into a thousand eight hundred, think about it is to understand why it is so powerful.

Chen Er looked at Li Jun and Wang Yong, who were a little stunned, patted Li Jun on the shoulder and said, "Hey, what do you want, it's really that the emperor is not in a hurry and the eunuch is in a hurry, and the people who assemble me are not good, aren't you two afraid." Li Jun was also changed by this beat, and quickly retorted: "Second brother, I am a real man, what eunuch is not too eunuch, it is a product of the feudal class, and New China does not like that thing." ”

Chen Er could only smile, this kid's heart is big enough. But then again, it's not okay to be a big part of their military industry. Those missiles designed and developed in the future will be hundreds of catties or even tons. In comparison, this anti-tank mine is a drizzle at best. Think of the atomic bomb, the hydrogen bomb, that is a weapon that can destroy a city, and the power is simply amazing.

This second anti-tank mine that has been done will naturally be handed over to Director Zheng Guoqiang, and only after obtaining the approval from above can this thing be mass-produced. Chen Er looked at Wang Yong and said, "It seems that this job has to be handed over to you." As he spoke, he pointed to the anti-tank mines on the ground.

Wang Yong had a bitter look on his face at this time, to say that this was a good thing to invite credit, but after experiencing the test explosion of the shooting range, Wang Yong's little heart was also a little nervous. Chen Er comforted and said, "Wang Yong, don't be afraid, this anti-tank mine is not so easy to detonate." I guess you don't have to explode even if you slam it on the ground. Just pay a little attention. Li Jun and I just went back first, and we were a little tired today. ”

After saying that, Chen Er pulled Li Jun and walked back, they didn't dare to study this thing in the research room. I could only find a relatively remote corner, so as not to be suddenly disturbed. Wang Yong was stunned for a while, and then stared at the anti-tank mines on the ground for a long time, and his mouth still kept muttering, "Bless, the organization bless me, don't have anything to do, I'm so old and don't have a wife." ”

Although Chen Er said that the conditions for the detonation of this anti-tank mine are more difficult. But Wang Yong didn't dare to be a little sloppy, he carefully held the big iron box and walked towards the director's office. Along the way, Wang Yong didn't even dare to stop for a while. The people who took the initiative to greet him were also selectively ignored. It wasn't until he walked safely to the door of the director's office that Wang Yong breathed a sigh of relief.

At this time, the door was suddenly opened from the inside, and Zheng Guoqiang was about to go to the cafeteria to eat. Wang Yong, who looked at the door, was also taken aback, and said a little angrily: "What are you doing here at this time." What is this thing in your hand? Wang Yong was also frightened by the sudden appearance of the master just now, but compared to the thing in his hand, the threat was a little greater, so Zheng Guoqiang's anger was insignificant.

Wang Yong said sternly: "Master, this is not an ordinary thing in my hand, this is an anti-tank mine that Chen Er took me and Li Jun just made. Don't look at it as inconspicuous, but just by holding ten catties, we have already seen its power. Let me tell you this, the boulder of three or four hundred catties was blown into small pieces all of a sudden, so let me go into the house and put it down. My arms are numb. ”

After listening to Wang Yong's description, Zheng Guoqiang couldn't care about eating, so he hurriedly opened the door for Wang Yong. Wang Yong carefully put the iron box in his hand on the table, and then he said while shaking his arms: "Master, my task is completed, and this iron guy is handed over to you." ”

Zheng Guoqiang grabbed Wang Yong, who was about to go out, but he didn't know the parameters of this anti-tank mine, so he couldn't let a time bomb be placed in his house. What kind of gold and silver treasures are given by people's gifts? My apprentice sent me an anti-tank mine all at once, which was really enough to test his endurance. Zheng Guoqiang thought helplessly. If it weren't for the fact that he was well-informed, he might have been really scared by this kid.

Zheng Guoqiang asked Wang Yong to sit on the chair and asked: "Wang Yong, you tell me about this thing, you don't want your master to be unable to sleep tonight." Wang Yong nodded and shook his head, and said, "Master, to be honest, I don't know much about this thing, just ask Chen Er tomorrow." By the way, master, this anti-tank mine is very safe, you will be fine if you leave it like this, I will hurry to the cafeteria when I am hungry. ”

After finishing speaking, he ran out quickly, Zheng Guoqiang could only lock the door carefully, and it would be clear to ask Chen Er tomorrow.

Besides, after Chen Er returned to the research room, he went back to the house alone after eating, but he couldn't sleep when he was lying on the bed, and his mind kept tumbling. Slowly, in a daze, a model of a mortar appeared in front of his eyes, and various numbers also popped out together.

Chen Eryi just sat up, and when he saw that the time was actually more than twelve o'clock in the evening, he was dreaming, but why did it feel so realistic, could it be that he was a ghost of the big military industrial system. After thinking about it carefully, sure enough, the model appeared clearly in front of me again. The Type 63 6O mm mortar is the first generation of small-caliber mortars in China, and it is very simple from construction to operation.

Compared with those large-caliber heavy artillery, the 6O mortar is easier to carry by small combat units, and can be used in various complex terrains, which can be said to have a lot of advantages. The Type 63 6omm mortar is composed of a barrel, a seat plate, a gun mount, a scope and an attachment 4 parts.

The barrel is composed of a barrel, a tail, a firing pin, a hoop ring and a handle. The rear end of the barrel is threaded and screwed with the tail of the gun, and the rear end of the barrel is in close contact with the inner plane of the tail to seal the discharge gas. The tail of the gun is internally rotated with a firing pin. The middle part of the body tube is screwed with a gun hoop ring, and is connected with the buffer sail rod with a spring pin, and the gun hoop ring is equipped with a handle. The gun carriage is composed of a gun hoop, a bracket, a frame leg, a high and low machine, a steering machine, a buffer machine, and a level adjustment machine.

The steering machine is used to drive the hoop bracket and the gun body to move left and right, and is composed of a screw, a steering screw, a direction nut and a runner. The right end of the screw barrel is sleeved with a liner and is installed in the ear hole of the bracket. And the external thread, tapered pin and runner connection. The inner thread of the screw barrel is screwed with the screw, and the screw is sleeved with a casing. One end of the casing is screwed on the direction nut and fixed with a standing screw. The direction nut is screwed on the high and low screw barrels and fixed with a tapered pin. When the runner is turned, the screw, the casing and the direction nut are fixed, but the screw rotates, and its hoop bracket drives the gun body to swing left and right, thus giving the gun body the direction of firing.

The high and low machine is used to connect the nut of the direction machine and drive the gun body to rise and land, which is composed of the high and low machine body, gearbox, large and small bevel gears, turnbars, screws and screws. The high and low machine body is connected with the left and right frame legs as a whole, which is used to carry the parts of the high and low machine. The screw barrel is sleeved with a sleeve and fixed at the upper end of the high and low body with a screw cover. The lower gearbox is equipped with a large bevel gear, and a rotary handle is installed on the large bevel gear shaft. The high and low screw rod is screwed with the screw, and the lower end is sleeved with a small bevel gear, and the guò tapered pin is connected with the nut as a whole, and is combined at the lower end of the high and low body. When the knob is turned, the large bevel gear drives the small bevel gear and the screw of the high and low machine to rotate in place, and the screw barrel rises and falls in the high and low fuselage, thus giving the gun an angle of fire.

The frame leg and the level adjustment machine are provided with a bundle gun belt on the right leg tube, and a standing hoe is welded under it. There is a leveling machine on the left leg tube.

The leveling machine is composed of slide pipe, adjusting screw, spring, screw ring, set collar, ratchet, set wrench, connecting rod, etc. When in use, pull the set wrench down, and the set clamp is released and slides over the slide tube to adjust the approximate level of the bracket. At this time, the adjusting screw is rotated, and the adjusting screw can only rotate in situ due to the restriction of the washer, so that the slide pipe drives the set collar to move up and down, and the high and low body swings through the guò connecting rod to adjust the precise level of the bracket.

The seat plate is used to withstand the recoil of the mortar when firing, and is composed of a main board, a mortar, a seat plate reinforcement and a gun tail lock. The gun tail lock is used to restrict the gun pestle from falling out of the mortar when recoil and wrenching, and is composed of a handle, a lock body, a lock seat, etc. Flip the handle to lock the pestle in the mortar.

Accessories include combination wrenches, fuze wrenches, wrenches, oil cans, hanging balls, guns, poles, etc. The gun is also equipped with a quadrant to check and assign a mortar angle of fire. These contents were quickly passed over in Chen Er's mind, and Chen Er also made up his mind to make the first 6O mortar, which would definitely be a big boost to the squadron in this period, and he would also be one step closer to the fourth-level military industry.
