A combination planter for arable land with adjustable row spacing

Abstract

The invention discloses a plowing and sowing combined machine capable of adjusting row spacing. Multiple discharge holes are formed in the bottom of a seed storage cylinder, according to the row spacing requirements of plowing and sowing, the positions, on an installation shaft below the seed storage cylinder, of plowing mechanisms are adjusted, sowing mechanisms are installed on the corresponding discharge holes, in the walking process of the combined machine, the plowing mechanisms plow land, and meanwhile the sowing mechanisms sow seeds in the seed storage cylinder in plowed grooves; the sowing mechanisms are driven by the installation shaft of the plowing mechanisms to conduct intermittent sowing, and sowing in the grooves according to preset spacing at intervals is achieved. According to the plowing and sowing combined machine capable of adjusting the row spacing, the structure is compact, the design is reasonable, the spacing between the plowing mechanisms can be adjusted according to the plowing requirement, the sowing mechanisms are driven by the installation shaft to conduct intermittent sowing, multiple-groove plowing can be conducted on the land, and meanwhile sowing is conducted at intervals according to the preset spacing in the grooves; therefore, the sowing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an arable land sowing machine with adjustable row spacing. Background technique [0002] The seeder is a planting machine that uses crop seeds as the object of sowing. According to the sowing method, the seeder can be divided into a spreader, a drill, and a hole seeder. The sowing machine is a sowing machine that distributes the scattered seeds evenly on the sowing field. The commonly used model is a centrifugal seeding machine, which is attached to the rear of the agricultural transport vehicle; the drill type is mainly used for small grains such as grains, vegetables, and pastures. Seed sowing operation, during operation, the walking wheel drives the seeding wheel to rotate, and the seeds in the self-seeding box are discharged into the seeding pipe according to the required sowing amount, and fall into the opened groove through the opener. Then the seeds are co...

AI Technical Summary

Problems solved by technology

But, the seed of existing sowing machine is to sow immediately, just may cause the generation of cavity

And usually the sowing spacing cannot be adjusted, so that the planter can only plow and sow with a single row spacing, resulting in poor applicability of the planter
