Embodiment Construction

[0027] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0028] Such as figure 1 , figure 2 As shown, the air-suction ratchet precision metering device of the present invention includes a seed box 6 with a seed window 4, a seed box 2 with a blower fan 1 and is installed inside the seed box 6 for Ratchet seed selection device for precise seed selection.

[0029] Wherein, the bottom of the seed box 6 is ladder-shaped, which is conducive to the concentration of the seeds 10 near the ratchet 5, and facilitates the ratchet 5 to obtain seeds during rotation.

[0030] The seed box 2 is fixedly connected to the back side of the seed box 6, and the upper part of the box wall adjacent to the seed box 2 and the seed box 6 has a seed window so that the inner space of the seed box 2 and the seed box 6 is connected. 4. The bottom of the seeding box 2 is conical, and a round pipe protrudes from it to connect with the seeding pi...

Abstract

The invention belongs to the technical field of agricultural machinery, and relates to an air-suction ratchet precise-metering seed-sowing device with stable performance, simple structure, and low technical requirement. The device comprises a seed-sowing tank (2), a seed storage tank (6), and a ratchet seed selecting apparatus used in precise seed selection. The seed-sowing tank (2) is fixedly connected on the back of the seed storage tank (6). A wall of the seed-sowing tank (2) adjacent to the seed storage tank (6) is provided with a seed-sowing window (4) making the seed-sowing tank (2) communicates with the internal space of the seed storage tank (6). A blower (1) is arranged on a wall on the upper part of the seed-sowing tank (2) facing the seed-sowing window (4). The installation position of the blower (1) is corresponding to the position of the seed-sowing window (4). The ratchet seed selecting apparatus is arranged in the seed storage tank (6). The ratchet seed selecting apparatus comprises a ratchet (5), wherein a tooth socket of the ratchet (5) is corresponding to the position of the seed-sowing window (4).

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a seed meter that can be used in sowing machines, in particular to an air-suction ratchet precision seed meter that can be used on large seed seeders such as corn. Background technique [0002] Precision seeding is an important part of increasing production in modern agriculture. At present, precision seeders are mainly divided into two types: pneumatic type and mechanical type. Compared with the mechanical precision seed meter, the pneumatic precision seed meter has the advantages of no damage to the seeds, less strict requirements on the shape and size of the seeds, good versatility of the whole machine, and high operating speed, and has been widely used in developed countries. Existing pneumatic seed metering devices can be divided into three types according to the working principle: air suction type, air pressure type and air blowing type. Among them, the air-suction see...
