Problems solved by technology

[0003] At present, the pneumatic seed metering device mainly has problems such as difficult filling of seeds, incomplete cleaning of seeds, unclean discharge of seeds, and low operating speed, which seriously affect the quality of sowing.
Moreover, when the seed tray or other parts of the seed meter are damaged, the disassembly and replacement process is relatively cumbersome

Embodiment Construction

[0051] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0052] Such as figure 1 and figure 2 As shown, the air-suction seed metering device of the present invention mainly includes a front housing 1 , a seed clearing mechanism 2 , a seed tray 3 , a seed unloading mechanism 4 , and a rear housing 6 of a transmission mechanism 5 . The seed clearing mechanism 2 is installed on the front housing 1, which can adjust the clearing position. The seed disc 3 is fixed on the transmission mechanism 5, and the seed unloading mechanism 4 is installed on the rear housing 6, which can be in contact with the seed disc 3. The rear housing 6 can be fixedly connected and disassembled with the front housing 1.

[0053] For details, see figure 1 , 4 And 5, the front housing 1 includes a seed layer height adjustment plate 101, a seed unloading baffle plate 102, an adjustment hole 103, a groove 104, a brush adjustment hole 10...

Abstract

The invention discloses an air suction type high-speed precision seed metering device with an auxiliary seed-filling seed disc. The air suction type high-speed precision seed metering device comprisesa front casing, a seed cleaning mechanism, the seed disc, a seed discharging mechanism, a transmission mechanism and a back casing. The air suction type high-speed precision seed metering device hasthe advantages that the periphery of a hole of the seed disc is provided with a bulge, so that the disturbance of the seed group is promoted, the function of seed supporting is realized, the seed suction air pressure is effectively reduced, and the operation speed is improved; by adopting the seed cleaning type of combining a seed cleaning brush and the seed cleaning mechanism in the seed cleaningprocess, the excessive seeds can be effectively cleaned; by adopting an ejection seed discharging type of combining a seed discharging wheel and a rectangular groove of the back disc surface of the seed disc in the seed discharging process, the uniformity of seed feeding is guaranteed; an outer casing of the seeding unit is of a clamp spring quick-detachable structure, so that the detachment andreplacement are convenient; the structure is compact and reasonable, the working speed is high, the stability and reliability are realized, and the requirement on air pressure is low.

Description

technical field [0001] The invention relates to the technical field of agricultural seeding, and mainly relates to an air-suction seed metering device. Background technique [0002] As the core component of mechanized sowing, the seed metering device has become the key to increasing production and income. At present, the widely used seed metering devices at home and abroad can be divided into mechanical type and pneumatic type according to the working principle. Although the mechanical seed metering device has simple structure, convenient maintenance, and low cost, it has gradually been replaced by the pneumatic seed metering device due to problems such as grain damage, unstable operating performance, and low operating speed during the operation process. The principle of pneumatic seeding is more adaptable to the shape and size of crop seeds, and basically does not cause damage to seeds, and has become the main method of precision seeding. [0003] At present, the pneumati...
