Metered-dose fertilizer gun head

Abstract

The invention discloses a metered-dose fertilizer gun head. The metered-dose fertilizer gun head comprises a water gunstock and a water injecting pipe, wherein an opening mechanism is arranged in an inner cavity of the water gunstock and is connected with the water injecting pipe; a closing mechanism is arranged at the front end of the water injecting pipe; and the opening mechanism and the closing mechanism are connected through a middle connecting rod arranged in an inner cavity of the water injecting pipe. The metered-dose fertilizer gun head disclosed by the invention has the beneficial effects that water injecting capacity in the water injecting pipe is controlled through the middle connecting rod arranged in the water injecting pipe, and the water injecting pipe is manufactured fromtransparent materials; a water quantity observation scale is also arranged on the outer wall of the water injecting pipe, so that fertilizing capacity or water injecting capacity can be more accurately controlled, the occurrence of situation that roots and stalks of crops are dead due to different fertilizing capacity is avoided.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a quantitative fertilizer nozzle. Background technique [0002] my country is a large agricultural country. With the improvement of agricultural technology, the output of various agricultural products has gradually increased. In agricultural technology, planting technology is also an important aspect to improve the quality and quality of agricultural products. In planting technology. Fertilization operations require fertilizers to be covered under the soil, precise placement and precise fertilizer control. Quantitative fertilization is conducive to greatly improving the production environment of crops, improving the quality of crops, increasing the yield of crops, and reducing the use of chemical fertilizers. The production cost is also conducive to the protection of the soil and the environment. In the traditional fertilization of crops, it is generally done by manually digging...

Problems solved by technology

Fertilization operations require fertilizers to be covered under the soil, precise placement and precise fertilizer control. Quantitative fertilization is conducive to greatly improving the production environment of crops, improving the quality of crops, increasing the yield of crops, and reducing the use of chemical fertilizers. The production cost is also conducive to the protection of the soil and the environment. In the traditional fertilization of crops, it is generally done by manually digging the pit with a shovel, pouring the fertilizer into the pit by hand, and then manually pushing the soil to bury the fertilizer. When operating in this way, the hammer head is not easy to operate, and it is easy to damage the crops. The fertilizer operator bends over and works hard. The labor intensity of fertilization is high and the work efficiency is low.

[0003] Moreover, artificial fertilization cannot accurately grasp the amount of fertilization. Generally, the amount of fertilization is controlled by experience. The same person may change the amount of fertilizer at different times, or because of fatigue, and the amount of fertilizer controlled by different people has a comparative advantage. large differences, which can easily lead to root burn or malnutrition in crops
