Abstract

The invention relates to a novel anti-blocking mechanism of a no-tillage sower. The novel anti-blocking mechanism comprises a rack, furrowing blade handles, furrow openers, drums, drum shaftings, division grid plates, a land wheel, universal couplings, driving chain wheels, gearboxes and gearbox fixing components, wherein each furrowing blade handle is fixed on the rack; each furrow opener is arranged at the bottom of each furrowing blade handle; a counter bore is formed in the top end of each furrow opener; each furrow opener and one gearbox fixing component determine the positions of each drum and each gearbox relative to the rack; the land wheel supplies power to each power input shaft through chain transmission; the adjacent power input shafts are connected by the universal couplings, so that one land wheel drives two or more anti-blocking devices; a pair of engaged bevel gears in each gearbox transfers the power to each drum; when the sower operates, the drums rotate to push front straws aside; the division grid plates behind the furrowing blade handles divide the straws thrown out by the drums by utilizing the convex arc shape characteristic so as to prevent the straws from falling into seed furrows opened by the furrow openers; the seed airing is avoided. The mechanism is applicable to a corn sower.

Description

technical field

[0001] The invention relates to an agricultural machine, in particular to a novel no-tillage seeder driving drum type anti-blocking device. Background technique

[0002] Conservation tillage is centered on straw, stubble mulching and no-tillage sowing. Among them, the no-tillage seeding technology is a technology that directly ditches, fertilizes, sows, and suppresses the surface covered with straw. This technology has significant economic, social and ecological benefits such as moisture conservation, increasing soil fertility, reducing water erosion and wind erosion, suppressing sandstorms, reducing operating procedures, reducing operating costs and increasing farmers' income. Therefore, the development of no-tillage sowing can effectively promote the sustainable development of agriculture in my country.

[0003] Straw mulching and no-tillage sowing are likely to cause difficulty in inserting ordinary seeders into the soil, entanglement of straw, or blocka...
