Embodiment 1

[0037] This embodiment provides a kind of rice and wheat collecting and distributing device, such as Figure 1-Figure 2 As shown, it includes an outlet unit 1, a cover plate 2, a tapered pipe 4, a straight pipe 5, a corrugated pipe 6, and a chassis 3. There are multiple outlet units 1, which are detachably connected to the cover plate 2. The outlet unit 1 is evenly arranged in a ring shape on the edge of the chassis 3 , the chassis 3 is installed concentrically with the tapered pipe 4 and the straight pipe 5 , and the bellows 6 is detachably connected with the tapered pipe 4 .

[0038] Specifically, an upper connecting plate 7 is installed on the top of the outlet unit 1, and the cover plate 2 is installed on the top 7 of the upper connecting plate, and is fixed together with the upper connecting plate 7, the outlet unit 1 and the chassis 3 through the first pin 8 . The outlet unit 1 , the chassis 3 , the upper connection plate 7 and the cover plate 2 form a distribution cham...

Embodiment 2

[0048] This embodiment provides a control method for the rice and wheat collecting and distributing device, including:

[0049] The positive pressure airflow passes through the bellows 6, and the airflow and the mixture of rice and wheat seeds are sent to the distribution chamber 9 through the straight pipe 5, and the rice and wheat seeds rise to contact with the cover plate 2, and the separation effect of the conical protrusion 201 and the partition 202 forms a uniform The seed flow enters the inlet 108 of the corresponding outlet unit 1, and the valve 104 is in an open state at this moment.

[0050] When a row of outlet cells 1 needs to be closed, the controller controls the motor 102 to rotate clockwise 90°, and the connecting rod 107 moves down to drive the valve 104 to rotate counterclockwise. block.

[0051] The blocked seeds fall into the return chamber 10 through the hole 301 of the bottom plate 3, and fall to the lower end surface of the straight pipe 5 under the act...

Abstract

The invention discloses a rice-wheat collecting and distributing device and its method. The technical scheme is as follows: it includes a plurality of outlet units distributed in a ring shape, and the top of the outlet unit is detachably connected with a cover plate; a straight pipe is installed under one end of the outlet unit , the outside of the straight pipe is covered with a chassis, the chassis is detachably connected to the tapered pipe, and the tapered pipe is connected to the bellows; a distribution chamber is formed between the outlet unit, the chassis and the cover plate, the tapered pipe and the straight pipe A return chamber is formed between the tubes; a valve is installed on the inlet side of the outlet unit, and the valve is connected to the valve control mechanism, and any outlet unit can be closed randomly under the action of the valve control mechanism. The outlet of the distributor of the present invention can be randomly closed according to the operation requirements. After the closure, the blocked seeds flow back to the bellows for secondary distribution, which improves the operation performance and work efficiency of the machine tool, thereby reducing the production cost.

Description

technical field [0001] The invention relates to the field of agricultural machinery research, in particular to a rice and wheat collecting and distributing device and method. Background technique [0002] The air-supplied collective row seeder has the characteristics of wide range of adaptability to seeds, high speed and wide width, simple structure and high seeding efficiency, and has gradually become the development trend of seeders. The research and development of large-scale high-performance rice-wheat compound operation tools suitable for large-scale operation will accelerate the mechanization of rice and wheat production, promote the transformation of my country's grain production mode to a green, efficient and sustainable direction, and ensure my country's food security and the reliability of agricultural production. Sustained development is of great significance. [0003] The inventors found that the current air-supply collecting and distributing device arranges seed...
