Planter capable of earthing and then dibbling as well as seeding method

Abstract

The invention discloses a planter capable of earthing and then dibbling as well as a seeding method. The planter comprises a rack, wherein a mark remover bracket, a traction frame and a film frame arearranged on the upper side of the rack; a first support and a second support are arranged on the lower side of the rack; a through shaft is arranged at the rear part of the film frame on the rack; anearthing roller is connected to the through shaft through connecting rods; a lifting lug is movably arranged on the through shaft; a soil crushing framework is movably connected to the other end of the lifting lug; a soil crushing roller is movably connected to the other end of the soil crushing framework; soil crushing teeth are uniformly distributed on the outer circumference of the soil crushing roller; the outer circumference of the soil crushing roller is in contact with the inner wall of the earthing roller. According to the planter disclosed by the invention, blocky soil is crushed into fine soil by utilizing the self-weight of the soil crushing roller and soil crushing teeth; the earthing roller is arranged in front of a dibbler, so that thin film holes are formed right above seeds, the seeds can normally break out of the film, the breaking resistance of seedlings is reduced, the labor intensity of artificial plate breaking is reduced and the emergence rate is ensured.

Description

technical field [0001] The invention relates to the technical field of agricultural production machinery, in particular to a seeder and a seeding method that cover soil first and then spot seed. Background technique [0002] The sowing method of the film-spreading seeders on the market is to spread the film first, then cover the soil, that is, the hole seeder is in the front, and the soil-covering roller is behind, so that the user can complete the soil covering the seeds while spreading the film. Making the seeds enter the natural growth state reduces human labor, improves the survival rate of seedlings, and improves the sowing efficiency. However, the current technical considerations are not comprehensive and have the following disadvantages: [0003] 1. Soil compaction: When the hole sower is planted, the seeds are covered with thick soil. After rain or irrigation, the soil above the seeds will be compacted, which prevents the seedlings from breaking through the soil and ...

Problems solved by technology

[0003] 1. Soil compaction: When the hole sower is planted, the seeds are covered with thick soil. After rain or irrigation, the soil above the seeds will be compacted, which prevents the seedlings from breaking through the soil and hinders the normal growth of the plants. Seedling emergence, which affects the emergence rate of crops, thus severely reducing production

After the seedlings are broken, the breaking of the knot itself requires a lot of manpower and material resources. At the same time, the process of breaking the knot will also cause damage to the seedlings, which will still affect the emergence rate and cause serious consequences such as reduced production.

[0004] 2. Dislocation of seedlings: Under normal circumstances, there will be small holes in the film directly above the seedlings to facilitate the seedlings to burst out of the film. However, the sowing mode of first sowing and then covering the soil is affected by the ductility and stretching of the mulch film. The impact of the rate will have a high probability of dislocation between the on-demand hole and the seedlings, which will also hinder the normal growth of the seedlings

cause seedling shortage and yield reduction

After the seedlings emerge, buttoning the seedlings can moderately reduce the situation of lack of seedlings and dead seedlings. However, due to the concentrated germination time of seedlings, the operation time is very short. If the operation is not timely, it will also cause dead seedlings and lack of seedlings.

At the same time, the process of buckling seedlings requires high precision, and the cost of labor and related production materials is also high.
