Embodiment Construction

[0065] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0066] Such as figure 1 To such as image 3 As shown, when the functional mode of the seed metering device is used as an air suction precision seed metering device, it mainly consists of a front housing 1, a seeding disc 2, a gear ring 3, a seeding disc positioning shaft 4, a retaining ring 5, and a bearing 6 , a chamber housing 7, an airway housing 8, an ingot nut 9, a buckle 10, and a motor 11.

[0067] Such as Figure 4 , Figure 16 and Figure 17 As shown, the front housing 1 includes a circular bottom plate and an annular wall perpendicular to the bottom plate, and the front housing 1 includes a seed pushing plate 101 and a seed scraper 112, wherein the seeds pass through the seed drop set on the bottom plate of the front housing 1. The pipe 109A enters the seed meter through the interface between the seed drop pipe 109A and the bottom plate, ...

Abstract

The invention discloses an air-suction and air-pressure type precise seed-metering device, which comprises a front shell, a planter plate and chamber shell, wherein the front shell is connected with the chamber shell through a buckle, the planter plate is arranged between the front shell and the chamber shell. The air-suction and air-pressure type precise seed-metering device can be rapidly dismounted, the overlap ratio of the parts is higher, the less parts are replaced, the switching between an air-suction type seed-metering device and an air-pressure type precise seed-metering device, so that the working efficiency is greatly improved.

Description

technical field [0001] The patent of the invention belongs to the technical field of agricultural machinery, and specifically relates to an air-suction type and an air pressure type dual-purpose precision seed metering device. Background technique [0002] With the development of precision agriculture and the adjustment of the agricultural industrial structure, precision seeding technology occupies an increasingly important position in modern agriculture, and precision seeding machinery is also widely valued by countries all over the world, and has a very broad application and development prospect. In terms of sowing technology, the precision seed meter is the core. The application of precision seed metering device can save a lot of high-quality seeds and reduce unnecessary tedious workload such as seedling setting and thinning; in addition, the performance of precision seed metering device directly affects the operation effect. [0003] At present, domestic pneumatic seed ...
