Chapter 70 Samples (33)

Zhang Qihang is back.

Previously, in order to determine the market acceptance of this product, Zhang Qihang spent half a month visiting construction companies, contractors, farms, growers, fruit farmers and even factory warehouse managers. Practitioners have finally determined the market acceptance of this product.

After he came back, the first thing Zhang Qihang did was not to understand the scale of the agricultural machinery start-up market, but to find out whether the sample car he had explained to build before he went out was completed.

At this moment, the things that he explained before he went out were placed in front of his eyes.

Comrade Wang Jiagui, the "chief engineer" of the two motorized carts, suddenly found himself a little nervous.

Yes, before Zhang Qihang took office, the technicians of the air compressor factory were almost gone, but some people did not leave due to various reasons, and Wang Jiagui was one of the few in the air compressor factory who understood. One of the old masters who has a little technology but didn't leave.

At the beginning, Wang Jiagui was an old master who was transferred from other units in the city as a technician. The reason why he still did not leave after the air compressor factory failed. First, because he was old, he might not be able to find good things when he went out. The second reason is that Wang Jiagui’s wife has passed away and several children have become a family. Although the salary provided by the Industrial Bureau to the air compressor factory is not much, it is enough for his personal expenses.

With wages and no work, and the fact that he is about to retire soon, Wang Jiagui is too lazy to toss, so he quietly waits for retirement. It was unexpectedly ushered in Zhang Qihang, a capable new factory manager. It was nothing at first, but after watching the new factory manager toss and toss, the air compressor factory was about to get up.

Of course it's a good thing to get up, who wouldn't like to get more money?

But at this moment, facing Zhang Qihang, the factory director and "chief designer", Wang Jiagui couldn't help but feel a little uneasy.

Zhang Qihang didn't notice this. His attention was all on the two carts. One was a unicycle and the other was a two-wheeler. The entire frame was completely redesigned. Compared with the current one Common unicycles and two-wheelers not only have larger frames, but also look more sturdy and sturdier.

Especially the two-wheeled cart, in fact, strictly speaking, this car can no longer be called a two-wheeled vehicle, but should be called a three-wheeled vehicle, because at the back of the cart, that is, under the handlebar, there is a The weighted universal wheel for walking, so that if the terrain allows, people only need to control the direction of the car, and the car can walk on its own.

Zhang Qihang, who was very satisfied with the workmanship of the two carts in front of him, nodded and asked Wang Jiagui, "It looks good, Old Wang, have you tested the performance of these two carts?"

"Factory director, don't worry, we have tried all the items you asked us to test," Mr. Wang nodded and said with a red face, "I even went to the construction site and the mountainous area to test it myself. , running like a 500-pound red brick, the contractor on the construction site kept asking me when our car would be put into production;
It’s no problem to go up the mountain, we went to the mountain specially, loaded 200 kilograms of fertilizer and went up the mountain easily…”

Zhang Qihang nodded again and again, and when Master Wang finished speaking, Zhang Qihang said, "So, the biggest problem now is the engine, right?"

"Yeah, the problem now is the engine." When talking about the engine, Mr. Wang frowned: "Director, our factory still has basic technical strength and production equipment. The air compressor factory was introduced back then. During the project, the old director introduced a complete set of welding, casting and finishing equipment for the air compressor factory, which can complete the overall casting and machining of the piston, crankshaft and cylinder block of the piston air compressor. Welding of gas cylinders, etc. can also be completed.

Although a lot of people have left now, as long as we recruit suitable workers, this is not a problem, but I and a few old buddies have carefully calculated that our equipment is only used to produce piston air compressors. To produce the imitation Jialing 50 engine is still too far away, so returning the engine becomes a big problem..."

Previously, in order to build these two prototypes, the air compressor factory had specially bought two second-hand Jialing 50 small motorcycles in order to obtain the two engines on the Jialing 50 motorcycle.

And because the power of the Jialing 50's engine is only 2.5 horsepower and the torque is only a pitiful 3.2 Nm, it cannot be used directly. Zhang Qihang also designed a two-stage reduction transmission mechanism for this unicycle, and added a reverse gear, which are "Forward-neutral-reverse", a more efficient chain drive is used between the engine and the transmission mechanism, the transmission mechanism and the wheels. After the torque of the two-stage transmission is amplified, it is no problem to use the power to climb mountains, but the speed It is also extremely "amazing": the maximum speed of the Jialing CJ50 motorcycle can reach about 50 kilometers per hour, while the maximum speed of this small cart is only 7 kilometers.

It’s no problem to build a prototype car like this, but if you really want to mass-produce it, you can’t buy second-hand motorcycles anymore.

Zhang Qihang nodded: "I will solve the problem of the engine. Now I want to know, except for the engine, what do you think of this project?"

Wang Jiagui hurriedly said: "Director, as long as you can solve the engine problem, this project will definitely make money. Did you know that when we tested on the construction site and in the mountains, those small contractors and the fruit farmers in the mountains all had red eyes. Now, with that posture, I can't wait to grab it directly."

Zhang Qihang nodded and said with a smile: "Don't worry, Old Wang, since I plan to do this project, I must have an idea for this one."

"That's good, that's good." Wang Jiagui breathed a sigh of relief, and nodded again and again: "I am relieved to hear your words from the factory manager."

As for how factory director Zhang intends to solve the engine problem, Wang Jiagui feels that this is not something he should worry about. I think the factory director has already considered this trouble when he decided to launch this project, and he is confident to solve the problem of engine supply, right?Otherwise how could he possibly decide to do this project?
