The whole family travels through time and space, and the three of them struggle together

Chapter 114 Divergent Thinking

Zhou Dajiang picked out the drawing of the third part of the sprayer and said, "The third part consists of the nozzle, spray boom, switch and bellows.

The switch is made of three wooden parts and is actually part of the spray boom."

As he spoke, he drew two joints facing opposite directions, one thick at one end and the other tapering in a stepped manner.

Then he pointed to the thin end and said, "This thin end is used to connect the spray rod and the corrugated pipe. Insert it into the corrugated pipe and secure it with wire. The same method can be used to connect the inlet and outlet to the corrugated pipe."

Then put the thick ends together, sandwich the switch in the middle, fix the three together, glue them firmly, then flip the switch up to turn it on, and down to turn it off. Is this all right, Old Tian?"

Carpenter Tian nodded, still speaking concisely, "No problem."

"Okay, then the next step is the sprayer boom. Actually, there's nothing much to say about the sprayer boom. You can use a bamboo tube or an iron tube.

Above that is the elbow and nozzle. The elbow can be made of copper pipe, simply heat it and bend it. The connection between the elbow and the spray bar is the same as before, so I won't go into detail. Let's talk about the end that connects to the nozzle. Because this elbow is going to be used for the nozzle, it's a little longer at the front for easier operation.

Finally, the nozzle is not too complicated, and the material required is copper."

Then he held up the small teacup and said, "The nozzle in the picture I drew is actually similar to this teacup. First, make a small round head in the shape of a teacup. The diameter of the round head should be large enough to fit into the elbow."

Then he gestured at the bottom of the teacup and said, "Remove the bottom of the round head, but keep the arc part at the bottom. After removing the bottom, roll the arc inward." As he spoke, he made a gesture of clenching his hand inward.

"Next, make a small copper piece with the same diameter as the elbow. I call it the 'spray piece.'

Once these are prepared, you can assemble the nozzle.

First, stack the rubber gasket and spray piece on the front end of the elbow. Keep the rubber gasket for now; if you can't figure out a replacement, replace it with something else. Once stacked, flip the small round teacup-shaped end upside down on it and secure it with wire or a mortise and tenon joint. This completes the third section.

Zhou Dajiang laid out the drawings of the first two parts and concluded, "The entire sprayer is actually very simple: a spray pump, pipes, and a spray boom.

The medicine pump includes a water pump and a medicine box. If cost is a consideration, the pipe can be divided into two parts. The part above the ground can be made of a corrugated pipe, and the part in contact with the ground can be replaced with a bamboo pipe. At most, there can be two more joints.

The spray boom is the part we just talked about.

Do you have any questions about the above? "

Zhou Dahai raised his hand. "If we need to spray pesticides, you have to carry both the pesticide barrel and the pump. It's too troublesome to move them. And if the water pipe is not long enough, you can only spray for a short while before you have to move it. Otherwise, you can't reach it. Can you think of a way to make it lighter?"

Zhou Dajiang grinned, pulled out a few more sheets of paper, and said, "I didn't want to talk about it today because I haven't finished the drawings, but since you asked this question, let's talk about it today."

After Zhou Dajiang finished speaking, he picked up the pen and filled in the unfinished parts on the first piece of paper, and then said:

“Today, I will lead you to expand your thinking.

This one is a wheelbarrow.

The carts we used to have included one-wheeled ones and two-wheeled ones, but there weren't any four-wheeled ones, right?"

Zhou Dahe: "All four wheels were pulled by animals."

Zhou Dajiang: "Yes, so I drew a four-wheeled cart that can be pushed by hand. The chassis of this cart is relatively low, and there is a baffle on the handle at the back, so that a lot of things can be loaded on it. Moreover, unlike a one-wheeled or two-wheeled cart, it does not need support, and this one is very stable.

The pesticide barrels, water pumps, pipes, and pesticide poles can all be placed on it and pushed around. Wouldn't that make spraying much more convenient?"

Everyone nodded after hearing this.

Zhou Dajiang then took out a second piece of paper and drew a square box with four wheels underneath. He then said, "If you think a wheelbarrow is too expensive, you can also make the pesticide barrel square and add four wheels underneath. That way you can push it around."

Then, still on the same piece of paper, he added a few more words and said, "This square box reminds me of the baskets that candidates use to carry into the imperial examinations. Everyone knows that candidates carry baskets when entering the examination room. If we could add four wheels to the bottom of the basket and make the handles draggable, wouldn't that make things much easier for the candidates?"

After he finished speaking, Zhou Dahai and the others didn't react much, just nodded. But it was different for the Xue brothers and Ma Lin. Their eyes immediately widened.

Yes! If this basket is equipped with wheels, then the money will roll in immediately!

Then he went on to say, "Do we usually use backpacks when we go shopping?"

Zhou Dahe nodded vigorously and said, "You even bought one for me."

"If we put too much stuff in the backpack, it will become heavy. What if we make a lighter frame, put two wheels underneath, and then fix the backpack on it? Or, if we don't use the backpack, we can just sew the cloth bag on top. Then we can pull it along."

Everyone, yes! This method is good. The exam basket is used by students, but they can use this one too!

Then, still on the same piece of paper, Zhou Dajiang added a few more strokes and continued, "The sprayer we talked about earlier is indeed convenient for spraying large areas of plants. But for smaller areas, such as the vegetable gardens in front of or behind the house, or a few flowers and trees in a small flowerbed that are infested with insects, wouldn't it be inconvenient to use a sprayer at this time?"

Everyone thought, yes, what should we do?

Seeing that everyone was thinking about it, Zhou Dajiang said, "Actually, you can also make a sprayer that can be carried on your back. Make a square medicine box, attach two sturdy straps to the box, put a pull rod on the left hand, and a hose and spraying pole on the right hand. This way, when you carry the medicine box on your back, you can press the water pump with one hand and carry the spray liquid with the other. You can also spray the medicine by yourself."

This time, not only the Xue brothers, but even the Zhou brothers' elder brother and younger brother were looking at him with shining eyes.

Zhou Dahe, this is great, we can study it further!

Zhou Dahai, you are still my younger brother. If I can do this, I can conquer the vegetable garden at home by myself!

The Xue brothers were even more direct. This and that were all about money!

After finishing this sheet of paper, Zhou Dajiang changed to another. This time, he drew a pipe and said, "The bellows we talked about before can also be used in many places. For example, when we take a bath, we usually use a bathtub. We don't feel it when we wash, but isn't it very troublesome to pour the water out?"

Everyone nodded, "Hmmmm!" After pouring it out, they were all sweaty again.

"If so, we can drill a hole in the side of the tub, install a connector, and then install the pipe on the connector and extend the pipe a little. When the tub is in use, we can plug the connector from the inside of the tub. When not in use, we can pull out the plug and the water will drain directly outside with the water pipe."

Everyone, wow, this water pipe is great!

Zhou Dajiang continued painting, and he drew a shelf and a big shower head around the water pipe?

Then, Zhou Dajiang continued, "The sprayer's nozzle can also be modified. Make it bigger and make it into a shower head. Then nail the sprayer rod directly to the wall, just like the picture I drew. Stand it up, and then install a shelf on the wall to put the shower head on. Then have someone outside add hot water to a bucket, and then pump the water outside. In this way, when you turn on the switch, water will flow out of the shower head, just like rain, and everyone can take a shower."

Everyone was completely shocked. Is this how you can take a bath?!
