Abstract

The utility model relates to a sowing device for evenly sown grains, characterized in that the surface of a sowing wheel is provided with socket grooves with spiral lines in staggered arrangement and a broom-shaped barrier device. The sowing device can evenly sow grains, precisely sow single grain with the advantage of no damage on seeds, and meet requirements for sowing seeds in different kinds and shapes by changing the shapes of the socket grooves.

Description

Sowing implement for even depositing granula

The utility model relates to a kind of pellet even broadcasting unit on the sower.

Escaper on the existing sower is an outer groove wheel, this complex structure, and cost height, and seed had damage can not evenly be sowed by individual particle, especially stopper adopts become mildewed brush or use rubber, it is inhomogeneous that seed is discharged.

The purpose of this utility model is to overcome the shortcoming and deficiency of above-mentioned prior art, and a kind of escaper that makes all even individual particle precise discharge of seed grain is provided, thereby guarantees seeding quality.

The purpose of this utility model is achieved in that

Pellet even broadcasting unit comprises seeds discharging box, blocks wheel, stopper and seed wheel, it is characterized in that:

A) be furnished with the cave groove on the seed wheel surface, groove every row in cave is arranged by spiral, the interlaced arrangement of cave groove in the ranks, and cave, end groove is the end face opening;

B) adopt broom shape stopper.

Owing to take such scheme, make to the utlity model has all even individual particle precise discharge of discharging seed, can change the cave groove shape simultaneously to adapt to the discharging of variety classes and difform seed.

Description of drawings:

Fig. 1 is that cave, seed wheel surface groove is arranged schematic diagram;

Fig. 2 is the cave grooved profile figure of Fig. 1.

Embodiment further specifies the utility model below in conjunction with accompanying drawing:

Pellet even broadcasting unit of the present utility model, its seed wheel (1) is furnished with cave groove (2) on the surface, groove every row in cave is arranged by spiral, the interlaced arrangement of cave groove in the ranks, its cave, end groove (3) is the end face opening, the cave groove shape is applicable to wheat seed sowing discharging among the figure, the discharging corn, the difform particle of soybean adopts difform cave groove, is Long Circle as wheat cave groove, make seed enter the cave groove by individual particle, the cave groove becomes helix to arrange, and one of every row also can be two or more, so that tens, in the ranks the cave groove is staggered, according to the requirement of each plant seeding, and the density difference, the speed of drilling difference makes the cave distance of cave, its seeding wheel surface groove, line-spacing is also different.

Adopt broom shape stopper, seed is stopped, controls strictness, do not damage seed.

When escaper passes through the chain drive of sower land wheel, seed wheel rotates in seeds discharging box, emission enters in the groove of cave under gravity and seed wheel rotary action in the upper container, by the soft elastic reaction of broom shape stopper, position, transfer part under seed wheel, the seed that the cave groove is outer stops, in order to avoid damage seed, the seed that only enters the cave groove can pass through, and makes it carry out the discharging of individual particle according to the arrangement of cave groove, thereby realizes the purpose of individual particle precise discharge.

Claims (1)

1, pellet even broadcasting unit comprises seeds discharging box, blocks wheel, stopper and seed wheel, it is characterized in that:

A) be furnished with the cave groove on the seed wheel surface, groove every row in cave is arranged by spiral, the interlaced arrangement of cave groove in the ranks, and cave, end groove is the end face opening;

B) adopt broom shape stopper.
