Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 Shown is a quantitative seed supply device for a centralized pneumatic seed metering device, including a seed box 1, a seed supply device housing 2, and an equal-width polygonal groove gear combination device 3. The seed box 1 is installed on the seed supply device housing 2, etc. The wide polygon groove gear combination device 3 traverses through the housing 2 of the seed supply device.

[0024] combine figure 2 , image 3 shown, according to figure 1 In the shown orientation, the seed supply device housing 2 includes a left support base 22, a left support plate 21, a rear connection plate 29, a front connection plate 25, a right support plate 26 and a right support base 28, a left support plate 21 and a right support plate 26 forms a cuboid frame by back connecting plate 29 and front connecting plate 25,...

Abstract

The invention discloses a quantitative seed supply device for a centralized air-supply type seed-metering device. The quantitative seed supply device comprises a seed box, a seed supply device shell and an equal-width polygonal groove gear combination device, wherein the equal-width polygonal groove gear combination device comprises a seed metering shaft, an equal-width polygonal groove gear mounted on the seed metering shaft, and two baffles mounted on the seed metering shaft and located on two sides of the equal-width polygonal groove gear respectively, and middle partition plates and blankwheels, wherein one middle partition plate is arranged between each baffle and one end of the equal-width polygonal groove gear; and one blank wheel is arranged between each middle partition plate andone end of the equal-width polygonal groove gear. The equal-width polygonal groove gear can destroy the contact between single seeds, so that the seeds are in a good flowing state, the seed filling performance is improved, a seed stirring device is omitted, the transmission process is simplified, the damage rate of the seeds is reduced, and the overall performance of the seed-metering device is greatly improved; and moreover, the flowability of the seeds can be enhanced, the missed filling index and the seed metering amount consistency variation coefficient are reduced, and precise seed metering of wheat, rice, barley and other seeds with poor flowability is easy to realize.

Description

technical field [0001] The invention belongs to the technical field of sowing in agricultural machinery, and in particular relates to a quantitative seed supply device for a centralized pneumatic seed metering device. Background technique [0002] The currently used seeders mainly include mechanical drills, air-suction precision seeders and centralized air-delivered seeders. The centralized pneumatic seeder simplifies the structure and transmission system of the whole machine by adopting the sowing method of mechanical quantitative seed supply and airflow redistribution into rows, and has a larger working width and higher working efficiency. The seed supply device is the core component of the pneumatic seeder, which plays the role of distributing the seeds in the seed box into a continuous seed flow. The currently widely used seed supply device is based on external sheave or grooved gear. Its disadvantage is that it has poor seed filling performance for seeds with poor mobi...
