Problems solved by technology

[0004] Traditional precision seeding devices mostly use a catheter-type seeding mechanism, and the seeds in each hole collide randomly in the catheter, resulting in poor consistency in reaching the seed bed for multiple seeds in each hole, and the landing speed is high, which is prone to bounce, causing each hole to bounce. Cave seed poor cavitation

Embodiment Construction

[0035] Such as Figure 1-4 As shown, a pneumatic seeding mechanism includes a casing 2, a transmission shaft 3, a sealing ring 4, a cover plate 5, a socket hole 6, a suction hole roller 7, a seed introduction pipe 8 and an air suction pipe 9;

[0036] The casing 2 is coaxially rotated and set on the transmission shaft 3. The casing 2 is connected to the transmission shaft 3 through bearings. The outer end surface of the casing 2 is provided with a bearing cover. The bearing cover is used for fixing and positioning the bearing. The sealing ring 4 is fixed by bolts. Installed on the end face of the housing 2, and a rubber sealing ring is provided between the sealing ring 4 and the housing 2 to ensure the sealing performance. There is a gasket, a cavity is formed between the shell 2, the sealing ring 4 and the cover plate 5, the socket hole 6 and the suction hole roller 7 are set in the cavity, the suction hole roller 7 is fixedly set on the transmission shaft 3, the socket hole ...

Abstract

The invention discloses a pneumatic seed metering mechanism and a pneumatic belt-sending precise seed metering apparatus. The pneumatic seed metering mechanism comprises: a casing, a transmission shaft, a sealing ring, a cover plate, a socket tube, a suction roller, a seed-guiding tube, a blowing tube, and an air suction tube, indents are arranged at the socket tube, the suction roller has a groupof suction holes corresponding to the indents, and the group suction holes comprises at least two suction holes, and a spherical column is arranged between any adjacent suction holes. The mechanism uniformly and accurately meters the seeds into a seed feeding mechanism, and does not damage the seeds during a seed metering process; and the pneumatic belt-sending precise seed metering apparatus comprises a frame, the above-mentioned pneumatic seed metering mechanism and the belt seed feeding mechanism, the belt seed feeding mechanism includes a large shell, a small shell, a driving pulley, a driven pulley and a synchronous belt, the synchronous belt has an equally spaced partition plates, and the belt seed feeding mechanism effectively reduces the seeding height of the seed metering device.According to the invention, the cavitation performance is increased, and accurate seed metering is realized.

Description

technical field [0001] The invention relates to the technical field of agricultural seeding, and mainly relates to a pneumatic seed metering mechanism and a pneumatic belt-feeding precision seed metering device applied thereto. Background technique [0002] The precision hole direct seeding technology can accurately distribute the seeds in holes in the field according to the required number of holes and hole distance according to the agronomic requirements of crops, which can save the amount of seeds required for sowing, and can make the seedlings uniform, Uniform seedlings create a reasonable field plant population structure for the growth of later crops, which is conducive to stable and increased production. [0003] The core working part of the mechanized precision hole seeding technology is the precision seed metering device. At present, two kinds of seeding principles, mechanical and pneumatic, are mainly used to realize the precise seed metering of hole sowing operatio...
