Pneumatic supporting spoon-drum combination type potato seed arrangement device

Abstract

The invention relates to a pneumatic supporting spoon-drum combination type potato seed arrangement device which comprises a seed supply mechanism, a seed taking mechanism, a seed clearing mechanism and a seed throwing mechanism; the seed taking mechanism comprises a pneumatic drum and multiple pneumatic supporting spoons which are sequentially and tightly installed at the periphery of the pneumatic drum; the pneumatic drum is driven by a power source to rotate, and a negative pressure is provided to the pneumatic drum by a negative pressure source; each pneumatic supporting spoon comprises asupporting spoon main body; each supporting spoon main body is provided with a supporting spoon air outlet hole which is communicated with an air hole channel of the pneumatic drum and a supporting spoon air inlet hole which is communicated with the corresponding supporting spoon air outlet hole; and the position, close to the supporting spoon air inlet hole, of each supporting spoon main body isprovided with a supporting groove. According to the pneumatic supporting spoon-drum combination type potato seed arrangement device provided by the invention, through the pneumatic supporting spoons,the pneumatic drum, a negative pressure fixed shaft and a pressure relief piece, the pneumatic supporting spoon-drum combination type seed taking, carrying and throwing process is realized; an intelligent seed supply module can realize automatic seed supplementation of a small seed tank and facilitates that a seed arrangement device continuously, efficiently and precisely arranges seeds at a highspeed; the seed clearing mechanism ensures unit precision seed taking; and the pneumatic supporting spoons and the pneumatic drum provide a novel technology of large-particle seed pneumatic seed arrangement.

Description

technical field [0001] The invention belongs to the technical field of sowing in agricultural machinery, and relates to a pneumatic scoop-supporting roller combined type potato seeding device. Background technique [0002] Potato is the fourth largest food crop in the world after corn, wheat and rice. At present, my country's total potato production has ranked first in the world, but the per unit yield is far below the world average level. Except for the gap in breeding technology, another constraint is my country's potato industry. The main bottleneck of development is the low level of mechanization of potato production (the mechanization level of potato production in my country is only 1%, while that of developed countries has exceeded 70%). At present, most of the existing potato seeding machines at home and abroad use spoon-belt seed metering devices. The seed metering device has low working efficiency and is not suitable for high-speed and high-efficiency seeding operati...

AI Technical Summary

Problems solved by technology

The vertical disc seed metering device has the characteristics of compact structure, good seeding performance and versatility, but due to the large size of potato seeds, the vertical disc type is difficult to apply for potato seeding

Although the drum-type seed metering device can be used in potato seeding, it has the disadvantages of high miss-seeding rate and re-seeding rate, low seeding qualification rate, and only relying on pneumatic adsorption of potato seed tubers, resulting in high power consumption of the seed metering device.
