Multifunctional sowing and fertilizing device

Abstract

The invention discloses a multifunctional sowing and fertilizing device. The multifunctional sowing and fertilizing device comprises a rack, wherein a walking mechanism is mounted at the bottom of therack; a soil turning mechanism, a sowing mechanism and a fertilizing mechanism are mounted on the rack; the soil turning mechanism comprises a soil turning bracket and a soil taking device which arefixedly mounted on the rack; the soil taking device comprises a screw rod which is vertically arranged and a direct-current motor for driving the screw rod to rotate; a base of the direct-current motor is fixedly mounted at the tail end of a transverse beam; an output end of the direct-current motor faces downward and is fixedly connected with the screw rod through a shaft coupler; a fixed block is further fixedly mounted at the bottom of the transverse beam through a plurality of stand columns; the bottom of the screw rod is in rotary connection with the fixed block; the screw rod is sleevedwith a sleeve; an outer side wall of the sleeve is further connected with a plurality of guide barrels through a plurality of positioning rods; a plurality of guide columns are distributed on the fixed block; and the guide columns are further in sliding connection with soil taking sheets respectively. The multifunctional sowing and fertilizing device can be used for taking soil and covering the soil at an original position and an extra soil covering mechanism is not needed; the multifunctional sowing and fertilizing device is convenient to use and the sowing and fertilizing efficiency is improved.

Description

technical field [0001] The invention relates to an agricultural production tool, in particular to a multifunctional seeding and fertilizing device. Background technique [0002] Seeder is a planting machine that takes 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 type, such as grain drill, corn hole seeder, cotton seeder, pasture spreader, etc. With the development of agricultural machinery, more and more farm work It is all done by machinery without manual work, which greatly improves work efficiency. [0003] However, the existing seeders are usually suitable for large-scale mechanized operation sites. When excavating the pits for planting, the plow blades are usually used to plow the land. The cultivated land is plowed, which causes a large amount of soil for plowing. After plowing, it is necessary to use a covering mechanism to cover the soil again on the seeds. After the soil is plowed, a ...

[0003] However, the existing seeders are usually suitable for large-scale mechanized operation sites. When excavating the pits for planting, the plow blades are usually used to plow the land. The cultivated land is plowed, which leads to a large amount of soil for plowing. After plowing, it is necessary to use a covering mechanism to cover the plowed soil on the seeds again.

After the soil is plowed, a large amount of soil will be plowed to a farther position. In this way, the soil must be restored manually, which is time-consuming and laborious.
