Double-cavity chute seed-protection type rice precision hole seeding metering device

Abstract

The invention discloses a double-cavity chute seed-protection type rice precision hole seeding metering device, and relates to the technical field of seed-metering devices. The device comprises a seedbox, a discharge plate, a feed shaft, left and right shell bodies, seed-partition hairbrushes, a seed-protection chute, a seed-clearing hairbrush and the like; left and right seed filling chambers are formed among the left and right shell bodies, the left and right seed-partition hairbrushes and the discharge plate; a certain amount of spoon teeth and seed guiding strips are evenly distributed onthe edge of the end face of the round discharge plate, the discharge plate drives the spoon teeth, the guiding function of the seed guiding strips fills spoon-teeth-shaped holes with seeds, after seed clearing, the spoon teeth filled with the seeds enter the seed-protection chute to achieve the seed protection, and the seeds enter a seed inputting area to achieve the seed inputting depend on theown weight of the seeds; and the lower portion of a seed metering device body is provided with a seed unloading block capable of quickly removing redundant seeds. The double-cavity chute seed-protection type rice precision hole seeding metering device has the advantages that single-cavity seeding of hybrid rice and double-cavity seeding of conventional rice are achieved under the condition of notreplacing the discharge plate, the problems that remaining seeds in the seed filling cavities are cleared difficultly and the like are solved, the seed filling performance is good, the structure is simple, and the device not only can seed rice, but also can seed wheat, soybean and other subsphaeroidal crops.

Description

technical field [0001] The invention relates to the technical field of seed metering devices in agricultural machinery, in particular to a double-cavity chute seed protection type rice precision hole sowing seed metering device, which is suitable for direct seeding of rice, wheat, soybeans and other crops. Background technique [0002] With the improvement of seed quality, the improvement of field weed treatment technology and the close combination of agronomy and agricultural machinery, live broadcast technology has also been widely used; compared with machine transplanting technology, live broadcast technology has the advantages of saving time, labor, cost and efficiency, Save seedling fields and other advantages. [0003] Precision sowing technology has the advantages of saving seeds, saving costs, no need for thinning, low labor intensity, etc., and can meet agronomic requirements after sowing, which is beneficial to plant growth. At present, precision sowing technology ...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a double-chamber chute-protecting rice precision hole sowing seed metering device, which can overcome the complex structure, high cost, high manufacturing precision and mechanical seed metering problems of the pneumatic seed metering device. The device has problems such as large seed damage, low seeding accuracy, and unsuitability for high-speed operation. It can realize precise and small amount of hole sowing, simple structure, low manufacturing cost, convenient maintenance and replacement, and rapid seed unloading, which effectively improves the seeding efficiency.

The invention can realize single-cavity sowing of hybrid rice and double-cavity sowing of conventional rice without changing the seeding tray, and solves the problem of difficulty in clearing out the remaining seeds in the filling chamber, and has the characteristics of good seed filling performance and simple structure. Not only rice, but also nearly spherical crops such as wheat and soybeans can be sown
