Description

Technical Field

[0002] my country is a large agricultural country. With the improvement of agricultural technology, the output of various agricultural products has gradually increased. Among agricultural technologies, planting technology is also an important aspect to improve the quality of agricultural products. In planting technology, fertilization requires that the fertilizer be covered under the soil, the placement position is accurate, and the amount of fertilizer is precisely controlled. Quantitative fertilization is conducive to greatly improving the production environment of crops, improving the quality of crops, and increasing the yield of crops. At the same time, it reduces the use of chemical fertilizers, which not only reduces the cost of agricultural production, but also helps to protect the soil and environment. In traditional crop fertilization, it is generally done by manually digging a pit with a hoe, pouring fertilizer into the pit by hand, and then manually pushing the soil to bury the fertilizer. When using this method, the hoe is not easy to operate and it is easy to damage the crops. The fertilizer operator has to bend over and work hard. The fertilization labor intensity is high and the work efficiency is low.

[0003] Moreover, manual fertilization cannot accurately grasp the amount of fertilizer applied, and generally relies on experience to control the amount of fertilizer applied. The same person may cause changes in the amount of fertilizer applied at different times or due to fatigue, and the amount of fertilizer controlled by different people is even more different, which can easily lead to root burn or malnutrition of crops.

[0029] Working principle: The lower part of the water gun handle 1 is connected to the water pipe 11 through the water pipe joint 16 and the joint 10, and the fertilizer water enters the water injection pipe 3 through the inner cavity of the water gun handle 1. Observe the scale on the outer wall of the water injection pipe 3. After the water volume reaches the required scale position, hold the water gun buckle handle 19 tightly. The water gun buckle handle 19 drives the slide bar 12 to move toward the front end of the inner cavity of the water gun handle 1, and then drives the water inlet switch 17 to move toward the front end of the inner cavity of the water gun handle 1. The water inlet switch 17 is squeezed and contacted with the annular limit block and closes the front end of the inner cavity of the water gun handle 1, so that the fertilizer water cannot continue to enter the water injection pipe 3.

At this time, the second spring 15 is stretched by force. After the fertilizer water in the water injection pipe 3 flows out, the water gun buckle handle 19 is released, and the first spring 18 and the second spring 15 lose their strength. The first spring 18 and the second spring 15 drive the water inlet switch 17, the slide bar 12, the middle connecting rod 5 and the water sealing cover 7 to reset under the action of their own elastic force. At this time, the inner cavity of the water gun handle 1 is connected with the water injection pipe 3, and the water sealing cover 7 closes the front end of the water injection pipe 3. This process is repeated to carry out quantitative fertilization on crops.
