Sowing device for farmland

Abstract

The invention discloses a sowing device for farmland. The sowing device comprises a frame, a lifting box, a lifting screw, a lifting motor, a reducer, a seed adding port, a seed storage tank, a fertilizer adding port, a fertilizer storage tank, a conveying pipe, booster pumps, feeding pipes, booster connectors, a drive motor, a support frame, transmission cases, a first turning gear, a second turning gear, a mounting part, a transmission rod, a tool rolling shaft, tools and a mounting rack. The sowing device has the advantages that the sowing device is compact in structure and convenient to use; the tools can be ascended and descended according to actual conditions, then pit digging depths can be adjusted, the sowing requirements of different regions and different soil texture can be satisfied, fertilizer is sprayed into soil before sowing, the tools roll to dig pits to allow the fertilizer to sufficiently contact with soil in the pits, and accordingly the nutrition absorption efficiency of seeds during sowing is increased greatly; sowing and fertilizing are integrated, the tool rolling shaft is uniform in stress and high in transmission efficiency, and the whole sowing device is high in stability and capable of effectively saving time and manpower.

Description

Technical field: [0001] The invention relates to the technical field of planting agricultural products, in particular to a sowing device for farmland. Background technique: [0002] With the development of society and the continuous advancement of science and technology, agriculture has also developed rapidly. The planter is a planting machine that uses crop seeds as the sowing object. The seeder used for a certain type or a certain crop is often named by the name of the crop, such as grain drill, corn hole seeder, cotton seeder, pasture spreader, etc. The existing seeder structure is mostly fixed, used for digging The height of the cutter in the pit is often a fixed structure, which is difficult to lift, which makes it extremely inconvenient to use in different regions and different soil properties, and it is difficult to meet various use needs. At the same time, it is difficult to fertilize it when planting, which needs to be done later. The fertilization operation greatl...

The seeder used for a certain type or a certain crop is often named by the name of the crop, such as grain drill, corn hole seeder, cotton seeder, pasture spreader, etc. The existing seeder structure is mostly fixed, used for digging The height of the cutter in the pit is often a fixed structure, which is difficult to lift, which makes it extremely inconvenient to use in different regions and different soil properties, and it is difficult to meet various use needs. At the same time, it is difficult to fertilize it when planting, which needs to be done later. Fertilization operation greatly reduces work efficiency, so we propose a liftable rotary tiller to solve the above problems
