Abstract

The invention discloses a seed-metering device capable of directionally sucking and metering seeds, which comprises a machine shell, a seed shifting mechanism, a seed cleaning mechanism and a transmission shaft, wherein the transmission shaft penetrates through the two ends of the machine shell, the seed shifting mechanism and the seed cleaning mechanism are fixedly arranged on the transmission shaft, the interior of the machine shell is divided into a seed bin and a seed-metering channel through a partition plate, a feeding port and a discharging port are formed in the machine shell, the feeding port and the discharging port are formed in the two ends of the seed-metering channel respectively, the seed bin and the seed-metering channel communicate at the feeding port, the seed shifting mechanism and the seed cleaning mechanism are both located in the middle of the machine shell, the seed cleaning mechanism is arranged at the feeding port, seeds move into the seed-metering channel from the seed bin, and the seed cleaning mechanism can scrape redundant seeds on the seed shifting mechanism into the seed bin. The designed seed-metering device for directional seeding can complete high-quality seeding operation of large-particle-size seeds; and the seed cleaning device is matched with a mounting device and can swing back and forth to clean redundant seeds at suction holes and carried by a position and direction adjusting device.

Description

technical field

[0001] The invention relates to the technical field of seed metering devices, in particular to a seed metering device for directional suction and discharge of seeds. Background technique

[0002] The air-suction precision seed metering device is often used for precision sowing of corn, soybeans, mung beans, etc. The advantage is that the air-suction precision seed metering device can achieve precise sowing, which can save a lot of seeds. , which is conducive to increasing and stabilizing production.

[0003] Seed metering devices are divided into mechanical seed metering devices and pneumatic seed metering devices. Pneumatic seed metering devices have the advantages of a wide range of seeds and can meet high-speed sowing operations. They are widely used in irregular seed sowing or high-speed sowing operations. However, in terms of sowing seeds with a large aspect ratio, there is no special seed metering device at present, and only a general-purpose pneumati...
