Description

A two ridge and eight row wheat mulching fertilization seeder

technical field

The invention relates to a two-ridge and eight-row wheat film-covered fertilizer seeder, in particular to the research field of agricultural machinery suitable for dry wheat sowing and fertilization.

Background technique

The existing wheat film-covered fertilization seeder is a seeder with two ridges and 6 rows or three ridges and 6 rows. When sowing in two ridges and 6 rows, there will be unevenness between two rows and 4 rows, while the three-ridge and 6-row seeder will sow Uniform, but requires a more powerful tractor to pull, and the utilization rate of the land is low. Neither of the two models can meet the needs of small farmers. The mechanism of the three-row 6-row seeder is complex, the production cost is high, and the land utilization rate is low; the overall sowing of the two-row 6-row seeder is not uniform, and the operation quality is unstable.

Utility model content

In view of the problems and defects in the above-mentioned prior art, the object of the present invention is to provide a two-ridge and eight-row wheat film-covered fertilization planter, which not only can meet the above-mentioned requirements, but also can realize stable operation when sowing, The land utilization rate is high, the work efficiency is high, and the work quality is stable.

The technical solution adopted by the present invention to solve the technical problem is a two-ridge and eight-row wheat film-covered fertilization seeder, which includes a frame, a lower suspension pin, an upper suspension pin, a driving ground wheel, and a supporting ground wheel. and the upper suspension pin are installed at the front end of the frame, and the driving ground wheel and the supporting ground wheel are respectively installed at the left and right sides of the rear end of the frame;

The upper end of the frame is successively equipped with a fertilizer box and a seed box, and the lower end of the frame is successively equipped with a ridging plate, a mold frame, a soil covering device, a pressing wheel, a fertilizer ditch opener, and a seed ditch opener. The box communicates with the fertilizer channel of the fertilizer opener through the fertilizer pipe, and the seed box communicates with the seed channel of the sowing opener through the seed tube. The sprocket on the frame is connected; the sprocket is connected with the main shaft of the seed row through the chain, and the main shaft of the seed row is connected with the main shaft of the fertilizer discharge through the chain; The main shaft and the composite fertilizer device are installed together;

The shovel handle of the fertilizer opener is fixed on the frame by U-shaped bolts and splints;

An adjustment device consisting of a screw and a spring is installed between the frame and the driving wheel;

The above-mentioned two-ridge and eight-row wheat film-covered fertilization seeder can realize operations such as fertilization and film-covering during sowing, and the sowing is even and orderly.

The working principle of this utility model is a two-ridge and eight-row wheat film-covered fertilization seeder:

When the seeder works under the drive of the tractor, the ridge plate performs ridge operation, the formwork covers the wound mulch on the raised ridge, and then the soil cover device covers the soil on the edge of the mulch, and then the pressing wheel will The plastic film that has been covered is compacted; when the planter is moving, the ground wheel rotates under the force of the ground, and the chain power is transmitted to the fertilizer discharge spindle and the seeding spindle in the fertilizer box and the seed box, and then the power is transmitted The fertilization operation is realized on the fertilizer discharger and the seed metering device. The seeds in the seed metering device fall through the seed tube into the groove opened by the sowing opener to realize the sowing operation. The ground wheel can be adjusted by the screw and the spring. The position on the frame is used to control the depth of seeding.

The beneficial effect of the present invention is that high-density planting can be realized when the small precision seeder is working, and the productivity is high, and wheat planting at different depths can be realized by adjusting the position of the ground wheel in the frame; the fertilization operation is realized; Laminating operation; It can save labor to a great extent and improve the quality of operation.
