Embodiment Construction

[0020] A kind of hybrid rice air-suction seed-suction plate of the present invention will be further described below in conjunction with accompanying drawing.

[0021] refer to figure 1 and figure 2 , it can be seen that the seed-suction part of the air-suction seed-suction plate plane of the hybrid rice air-suction seed-suction plate is composed of multiple groups of parallel air passages 3 arranged side by side; The through holes matched with the channel 3; the two ends of each group of parallel air channels 3 are open, and one end matches the through hole on the frame I1; the other end matches the through hole on the frame II11; the two sides of the combined plate I2 pass through the bolt They are respectively fixedly installed on one end of frame I1 and frame II11 and are in close contact with the parallel air passage 3; the two sides of the combined plate II7 are respectively fixed and installed on the other ends of the frame I1 and frame II11 by bolts and are in close ...

Abstract

The invention discloses an aspirated-air type seed sucking plate used for hybrid rice seedling raising and seeding. The aspirated-air type seed sucking plate mainly comprises a frame I, a frame II, parallel air passages, an air cavity, an air pressure valve, a flexible pipe and the like. The seed sucking plate is formed by combining multiple groups of parallel air passages, seed sucking holes are distributed in the parallel air passages in a staggered manner, each parallel air passage is an independent air cavity, and air flow in the air cavity is uniform and stable. The aspirated-air type seed sucking plate disclosed by the invention can be applied to rice seedling raising and precise seeding of hybrid rice, seeding uniformity is effectively improved, and further seeding quality is improved.

Description

technical field [0001] The invention belongs to the field of precision sowing of agricultural machinery, and in particular relates to an air-suction seed suction plate suitable for hybrid rice seedling raising. Background technique [0002] With the rapid development of my country's economy and society, the continuous progress of agricultural science and technology, the implementation of precision agriculture, the cultivation of hybrid rice has entered the stage of large-scale promotion. The agronomic requirements of hybrid rice are different from those of conventional rice. When seedling precision sowing of hybrid rice, the seeds need to be exposed; secondly, 1-2 seeds must be guaranteed for each seedling area, at most not more than three, at least Guaranteed one. Less than one seed will cause missing seeding, and more than three seeds will inhibit the tillering ability of the plant, affect yield and cause waste of good seeds. The geometric shape of hybrid rice is also di...
