Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] The invention provides a kind of seed-taking mechanism, such as Figure 1-5 ,include:

[0038] housing 1; and

[0039] The sheave 2 connected to the housing 1 is rotated. Between the outer source of the sheave 2 and the inner wall of the housing 1 are formed an abutment area 20 , a seed picking area 21 , a delivery area 22 and In the release area 23, the sheave 2 located in the abutment area 20 abuts against the inner wall of the housing 1, the seed picking area 21 is vertically lower than the top of the sheave 2 on the horizontal plane, and the surface of the sheave 2 is uniformly provide...

Abstract

The invention relates to a seed taking and discharging mechanism. The seed taking and discharging mechanism comprises a shell and a grooved wheel, wherein a seed cavity for accommodating seeds is formed in the shell, the grooved wheel is rotationally connected into the shell, an abutting area, a seed taking area, a conveying area and a releasing area which are sequentially arranged in the circumferential direction of the grooved wheel are formed between the outer edge of the grooved wheel and the inner wall of the shell, the part, located in the abutting area, of the grooved wheel abuts against the inner wall of the shell, the seed taking area is lower than the horizontal plane where the top of the grooved wheel is located in the vertical direction, multiple seed grooves are evenly formedin the surface of the grooved wheel, a seed inlet and a seed outlet which communicate with the abutting area and the releasing area are formed in the shell, and the rotating direction of the grooved wheel is the same as the rotating directions of the abutting area, the seed taking area, the conveying area and the releasing area. The invention further provides a seeder comprising the seed taking and discharging mechanism and a seed taking and discharging method. According to the seed taking and discharging mechanism, through low-position seed taking, the risk that seeds are clamped between thegrooved wheel and the shell is reduced, so that the possibility that the seeds are damaged and the later emergence rate is decreased is reduced, the seed taking and discharging mode is novel, and theseed taking and discharging mechanism is suitable for practical application.

Description

technical field [0001] The invention relates to the field of tillage equipment, in particular to a mechanism for taking and arranging seeds, a seeder and a method for taking and arranging seeds. Background technique [0002] At present, most seeders use grooved wheel type seed metering device for seeding, and generally it is an external grooved wheel type seed metering device. Cooperate, open the seed groove on the outer peripheral wall of the sheave, the seed taking port and the seed discharging port of the seed box are arranged on the rotation path of the seed tank body, when the seeds falling into the seed box enter the seed tank, they are picked up by the seed located in the seed taking port. The trough gets driven to the seed discharge outlet for sowing. However, this kind of seed meter needs the close cooperation between the grooved wheel and the seed box to realize the precision of seed picking and seeding and ensure the precision of sowing. However, due to the close...
