Description

Buckwheat seeder

Technical Field

The invention relates to a seeder, in particular to a buckwheat seeder.

Background

The traditional seeding in the past is that an animal drives the thill formula and pulls the drill barrow, still need one person to help the drill barrow (be exactly drawing the cage and rein forward near the animal head, prevent to walk partially), one person is carrying the drill barrow behind and is shaking seed placement, the drill barrow bell is pulled the seed rhythm and is fallen into drill barrow reposition of redundant personnel and drips into three and a string is dropped intoDrill barrowAnd the leg pipeline falls into the soil from the pipe hole at the back of the drill share. With the continuous promotion of the adjustment of the agricultural production structure, modern agricultural machinery cannot exert power on mountainous regions, terraces and hills.Some large-scale seeders in mountain areas cannot be used. The cultivation method is distributed in vast mountainous areas and rural areas in hilly areas, and is reserved for women, children and old people in remote mountainous areas to cultivate scattered small land, terraced fields and curved slope lands, so that the animal power is reduced day by day, and the cultivation is difficult. One of special products in mountainous areas is buckwheat, buckwheat is usually sowed in the middle and last ten days of 6 months, rainfall is unstable, and a buckwheat sowing machine is needed to ensure the emergence rate.

Disclosure of Invention

The invention aims to provide a buckwheat seeder capable of ensuring the emergence rate.

The invention is realized by the following technical scheme:

a buckwheat planter comprising: the seed box comprises a frame, advancing wheels, a seed box, a furrow opener, a seed discharging pipe and a press wheel; the front end of the rack is provided with an advancing wheel, the handle is arranged on the rack, the seed box is arranged on the rack, the furrow opener and the small press wheel are arranged below the rack, a furrow covering sheet is arranged below the rack behind the small press wheel, and a large press wheel is arranged below the rack behind the furrow covering sheet; the lower part of the seed box is provided with a regulating valve, and the lowest end of the seed box is connected with a seed discharging pipe.

The advancing wheel rotates to drive the small chain wheel to rotate, the small chain wheel drives the large chain wheel to rotate through the chain, the large chain wheel rotates to drive the lower seed wheel shaft to rotate, so that the lower seed wheel mounted on the lower seed wheel shaft is driven to rotate, seeds in the grooves on the lower seed wheel uniformly fall into the seeding pipe along with the rotation of the lower seed wheel, and uniform seeding is achieved.

The cover groove pieces are two pieces, and the left and the right of the cover groove pieces are in a splayed shape.

The included angle between the cover groove sheet and the central line of the frame is 30-45 degrees.

The seed tube is sleeved in the tube of the furrow opener.

The small press wheel is arranged on the furrow opener.

The small press wheel is one and is positioned below the central line of the rack, and the diameter of the small press wheel is 8 cm.

The two large press wheels are arranged side by side, and the diameter of each large press wheel is 20 cm.

The invention has simple design, simple and convenient operation and convenient maintenance; is especially suitable for seeding buckwheat in mountain areas. This seeder adopts dual suppression when the soil moisture content lacks or is suitable, does not run the soil moisture, guarantees the rate of emergence, is this mechanical innovation part.

Drawings

Figure 1 is a schematic structural view of the present invention,

fig. 2 is a top view of fig. 1.

In the figure: 1-a frame, 2-a regulating valve, 3-a handle, 4-a seed box, 5-a chain, 6-a forward wheel, 7-a small chain wheel, 8-a forward wheel shaft, 9-a large chain wheel, 10-a seed discharging wheel shaft, 11-a furrow opener, 12-a seed discharging pipe, 13-a small press wheel, 14-a cover furrow slice, 15-a large press wheel and 16-a seed discharging wheel.

Detailed Description

The invention is further illustrated by the following figures and examples.

As shown in the drawings, a buckwheat planter includes: the device comprises a frame 1, a front wheel 6, a seed box 4, a furrow opener 11, a seed sowing pipe 12 and a press wheel; the front end of the frame 1 is provided with a front wheel 6, the handle 3 is arranged on the frame 1, the seed box 4 is arranged on the frame 1, the furrow opener 11 and the small press wheel 13 are arranged below the frame 1, a cover ditch sheet 14 is arranged below the frame 1 and behind the small press wheel 13, and a large press wheel 15 is arranged below the frame 1 and behind the cover ditch sheet 14; the lower part of the seed box 4 is provided with an adjusting valve 2 which can adjust the discharging amount of seeds, and the lowest end is connected with a seed discharging pipe 12. Adopts dual suppression, does not run the soil moisture, guarantees the rate of emergence.
