Automatic piercing hole fertilization mechanism

Abstract

The invention relates to an automatic hole-piercing fertilization mechanism, which includes a main rod body, a movable plate mounted on the main rod body in parallel sliding, a fertilizer discharge device installed on the movable plate, and a hole-piercing duckbill. The main rod body is vertically arranged, The movable plate is vertically arranged on the side of the main rod body. On the side of the movable plate, a guide sliding sleeve matched with the main rod body is fixed through the connecting block. On the side of the main rod body, an electromagnet located directly above the movable plate is arranged. The electromagnet The telescopic rod is vertically arranged and its lower end is vertically fixed on the upper end surface of the movable plate. The duckbill in the piercing hole includes a fixed duckbill body and a swinging duckbill body that can be opened and closed freely. The duckbill is directly above and fixed with the movable plate, and the lower fertilizer mouth of the fertilizer discharger is directly facing the inner cavity of the duckbill for pricking the hole downwards, and the lower end of the main rod body is also provided with a stopper for opening the duckbill for pricking the hole; the present invention The plants are fixed and fertilized quantitatively by piercing the duckbills, so as to improve the utilization rate of fertilizers and reduce costs.

Description

technical field [0001] The invention relates to the technical field of fertilization equipment, in particular to an automatic hole piercing fertilization mechanism. Background technique [0002] Fertilizers can maintain and improve soil fertility and provide the nutrients needed for crop growth. In addition to applying basal fertilizer during the crop growth cycle, topdressing operations need to be carried out in the middle and late stages of crop growth to ensure sufficient soil fertility and meet crop growth needs, especially For corn, intertillage fertilization is an important part of corn field management and plays a vital role in the growth of corn. The yield increase effect of corn fertilization mainly depends on the variety characteristics, soil fertility, fertilizer types and fertilization techniques. Fertilization of corn Fertilizer should be topdressed in stages and deeply. The utilization rate of deep application of fertilizers is much higher than that of surface ...

[0002]Fertilizers can maintain and improve soil fertility and provide nutrients needed for crop growth. In addition to spreading base fertilizer during the crop growth cycle, topdressing is also required in the middle and late stages of crop growth To ensure sufficient soil fertility and meet the needs of crop growth, especially for corn, intertillage fertilization is an important part of corn field management and plays a vital role in the growth of corn. The effect of corn fertilization on increasing yield mainly depends on the variety Characteristics, soil fertility, fertilizer types and fertilization techniques, etc. Fertilization of corn should be topdressed in stages and deep topdressing. The utilization rate of deep application of fertilizers is much higher than that of surface application, especially for volatile chemical fertilizers, the effect of deep application is better. Therefore, it is necessary to change topsoil fertilization to deep fertilization to improve the utilization rate of fertilizer and facilitate the absorption of plant roots; at present, the existing mechanical topdressing methods are mostly two forms of surface fertilization and furrow plow underground deep fertilization. Insufficient use of fertilizers leads to waste of resources; underground trenching and deep fertilization can better solve the defects caused by throwing ground fertilizers, but repeated trenching and fertilization of the soil leads to increased water loss in the soil and low operating efficiency. In addition, deep underground fertilization requires a relatively high distance between the fertilization position and the growth of the crops. During the fertilization process, it is easy to damage the roots of the furrow and plow, which affects the growth of the crops.
