Chapter 382 Pulley Block
After closing the pigpen door, Zhao Yeqing put down the ladle in his hand and went to the door to look.
Mu Xi put the noose in his hand around the neck of a hybrid sheep and pulled it towards home, but the sheep struggled desperately.
The other mixed-breed sheep that had been relatively quiet also began to stir.
Seeing this, the other two dogs who were looking after the pig at home hurried forward to help. With the help of the four dogs and Mu Xi's noose, they finally made the pig walk back obediently.
Zhao Yeqing couldn't help but click his tongue. There was indeed some wildness in this blood.
The last wave of forage grass at home has been harvested, and the old seedlings in the field can no longer be expected to continue growing and wait for the next harvest.
Generally, the yield of forage grass sown once will drop sharply after three harvests, and the soil must be turned over and sown again.
Considering that if this hybrid sheep is still so wild, I can only keep it at home and feed it for a period of time to soften its temper.
Keeping goats locked up consumes more feed, but goats can easily get sick if they are locked up all the time, so they need to be let out to get some fresh air every few days. The remaining silage is enough to feed these goats.
Mu Xi's arms were already sore, and after pulling the sheep, they became even more so. During dinner, the hand holding the chopsticks almost became like Parkinson's.
Zhao Yeqing's eyes seemed a little pitiful.
Zhao Yeqing couldn't help but want to laugh: "What? You still want me to feed you?"
Mu Xi stood up and took a spoon to eat. He didn't look embarrassed at all, but his ears remained red for ten minutes before they went away.
Even if Zhao Yeqing saw it, he would not show mercy. Who asked him to be so stubborn and move two barrels of oil? At this time, being so stubborn might cost him his life at any time.
He just needs to learn a lesson from this.
But you have to rub the medicinal wine. Rub it for ten minutes when you wake up in the morning, and rub it for a while longer before going to bed at night to relax the tense muscles.
After getting up again, Mu Xi's hand was finally almost healed. He immediately volunteered to dig up grass roots in the field and prepare to sow forage grass.
Zhao Yeqing still had to work on her pulley system, so she waved her hand and let Mu Xi go.
Even if your muscles are sore, you can't just sit there and do nothing, as that will make the pain worse and take longer to heal.
The grass roots in the ground are still ten centimeters long on the ground. It doesn't take too much effort. You just need to bend down, grab the surface part, pull it up and throw it away.
Mu Xi had just pulled out two blades of grass when he saw a round little mushroom, which was pressed under a handful of weeds that he had thrown away when he was mowing the grass.
When I picked it up and took a look, it turned out to be a straw mushroom.
This kind of mushroom likes to grow under haystacks. The high temperature environment of the wet haystack after the rain is a paradise for this kind of mushroom.
If there is one here, there must be one in the fields as well.
After the wheat was harvested and threshed this year, the hay house was almost full of straw and hay. A lot of the remaining wheat straw was wet by the rain, so people were too lazy to dry it and just threw it in the field.
Mu Xi threw the grass roots in his hand aside and walked to the straw to turn them over...
Sure enough, there was a large patch of it. There were seven or eight small straw mushrooms in just an area the size of a palm.
Mu Xi didn't even bother to pull out the weeds. He picked all the straw mushrooms underneath and put them in his clothes to take them home.
Zhao Yeqing saw that Mu Xi came back after just ten minutes out, and was about to ask him when he saw a bag of straw mushrooms in his arms.
He couldn't help but chuckle: "Looks like we'll have chicken stewed with straw mushrooms for dinner tonight." There happened to be more and more chickens in the chicken coop recently, and the two of them had no time to collect eggs, so the chicks were hatching in groups.
Just as he finished speaking, the ducks lined up again to go out for a bath. After counting them, he found that there were only nine ducks.
The last female duck laid eggs some time ago and has been incubating them in the nest ever since, rarely coming out to play in the water.
In order to keep domestic ducks laying eggs, the task of incubating eggs is usually handed over to hens or done manually. Only a small number of native ducks in rural areas and wild ducks still retain the habit of mother ducks sitting on the nest.
It looks like in ten days or so, a group of squeaking little creatures will hatch from their shells at home.
After the little episode, Mu Xi put the straw mushrooms into the kitchen and went out to pull weeds. Zhao Yeqing was the only one left in the yard, polishing a pile of wooden parts.
March 3040
Zhao Yeqing had not expected that a small part that he thought was simple would take so long to make. The lack of experience in carpentry led to constant rework. It was useless to rework the parts that didn't fit together, and he had to get new materials and do it again.
Mu Xi wanted to offer his help but was rejected by Zhao Yeqing. In the beginning, he did indeed become bald, but after doing carpentry for a long time, he became more and more addicted to it.
The chisel carved a little bit, the sandpaper polished a little bit, and my originally impatient heart slowly calmed down.
The finished pulley system still needs to be tested to see which method saves the most effort. The two of them searched their memories in their minds, and after trying several combinations, they found that the combination of a moving pulley and a directional pulley for the upward pull was the most labor-saving.
When only one pulley is used, the required pulling force is the same as the weight of the gasoline barrel. By using two pulleys, one moving and one static, to pull the rope at the same time and pulling the rope from top to bottom, the required force can be saved by half.
When using two pulleys and pulling the rope from bottom to top, the force required is only one-third of the original force.
......
The forgotten physics knowledge always came back to her mind in various ways.
The final step is to simply fix the mounting bracket of the directional pulley to the edge of the cliff.
Mu Xi had previously driven the expansion rivets into the cliff using a small portable electric drill that was also in the climbing bag. There were also large rocks on the edge of the cliff, and the two men's idea was to drill holes in the rocks and connect the bracket to the cliff with expansion rivets.
After the other movable pulley is connected to the rope, it is hung together with the gasoline barrel below. When the rope is pulled, the two pulleys move at the same time, so that the gasoline can be stably lifted up from the foot of the mountain.
By combining the pulled-up rope with the previously made rotating wheel, the rope can be tidied while being pulled, and it can also play a fixing role to prevent the gasoline barrel from accidentally falling due to loose rope caused by unstable hands.
Zhao Yeqing polished the pulley assembly very smoothly. After all, the effort that the pulley assembly can save does not include the friction force. In order to save enough effort, the wheel must be smooth enough.
The weight of the wheel and the rope are also factors to be considered, but the requirements cannot be too high now. Zhao Yeqing has run out of ideas to make such a device.
I used to be distracted in class, and now I regret it every time I think of her.
The importance of compulsory education is perfectly closed at this moment.
I wish I could find two more physics books to study every day. If I had studied hard, the agricultural facilities at home might have been automated long ago. There are so many parts, metals and car engines in the tourist area...
If there were a physics expert here, he would have modified a lot of agricultural machinery long ago.
Mu Xi went to get the beehive today. As soon as she entered the room, she saw Zhao Yeqing with a look of emotion. After asking, she found out what she was thinking. She handed her a large bucket of honeycomb and said,
"Okay, stop imagining. If a physics expert were here, he might not be able to tell the difference between onions and garlic. If he can't grow food, he might starve to death."
