Air-suction vibrating disk type precise seed feeding device

Abstract

The invention discloses an air-suction vibrating disk type precise seed feeding device. The device comprises a bearing and lifting assembly, a seed separating assembly and a negative-pressure seed suction assembly, wherein the bearing and lifting assembly is located at the bottom of the device, the seed separating assembly is arranged on one side of the bearing and lifting assembly, and the negative-pressure seed suction assembly is arranged on the side of the seed separating assembly. The device is scientific, reasonable and safe and convenient to use, a vibrating disk shell is used as a seedstorage device of the seed separating assembly so as to separate adhering seeds, a soil separating block is adopted to be inserted into soil intermittently to separate lower soil to two sides, when the soil separating block is retracted after separating soil, a bottom plate can push and scrape the soil adhering on two sides of the soil separating block, the adhering soil is purged by exhausting,blockage caused by soil accumulation is prevented, and by adoption of negative-pressure suction and centrifugal seed separation tank for seed separation, the seed separation can be more uniform on thebasis of intermittent seed separation.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an air suction vibrating disc type precision seed metering device. Background technique [0002] The continuous maturity and improvement of mechanization is the development trend of agriculture. The seeding device in the prior art adopts the seed outlet method with a leak at the bottom of the storage bin, especially when the seeds are wet, it is very easy for the seeds to squeeze each other and block the seeds. The phenomenon of the opening makes the seeding operation unable to continue. This device uses the vibrating plate shell as the seed storage device of the seeding device. Under the action of thrust, the seed opening is located above the equipment, and under the vibration of the vibrating plate, Separate the sticky seeds, and it is difficult to block the seed outlet. The sowing hole opening device in the existing sowing device is prone to the phenomenon of so...

[0002] The continuous maturity and improvement of mechanization is the development trend of agriculture. The seeding device in the prior art adopts the seed outlet method with a leak at the bottom of the storage bin, especially when the seeds are wet, it is very easy for the seeds to squeeze each other and block the seeds. The phenomenon of the opening makes the seeding operation unable to continue. This device uses the vibrating plate shell as the seed storage device of the seeding device. Under the action of thrust, the seed opening is located above the equipment, and under the vibration of the vibrating plate, Separate the sticky seeds, and it is difficult to block the seed outlet. The sowing hole opening device in the existing sowing device is prone to the phenomenon of soil accumulation and adhesion on the equipment, and the existing equipment with the device for digging the sowing hole is different from the The friction of the bottom surface is large, and it is easy to be blocked and damaged at the same time. The soil blocks are inserted into the soil intermittently to separate the soil below to the two sides, so that the planting pits are clearly defined, and compared with the design of the bottom fixed digging device, it is extremely The movement resistance of the device is greatly reduced. When the soil block is retracted after the soil is divided, the bottom plate will push and scrape the sticky soil on both sides of the soil block to prevent the block from being blocked and difficult to recover. , and the exhaust branch pipe can purge a small amount of soil contaminated on the side wall of the soil block to strengthen the prevention of blockage caused by the accumulation of soil. The method of negative pressure suction and centrifugal separation groove is used to make the device work intermittently. On the basis of sorting, the sorting is also more uniform, so people need an air-suction vibrating disc precision seeding device to solve the above problems
