Tillage-free anti-blocking device with obliquely arranged driving grass flipping wheels

Abstract

The invention relates to the mechanical field of agriculture, and discloses a tillage-free anti-blocking device with obliquely arranged driving grass flipping wheels. The tillage-free anti-blocking device comprises a machine frame, a gearbox mounted on the machine frame, and tillage-free anti-blocking units, wherein each tillage-free anti-blocking unit comprises a grass flipping frame, a furrow opener, a grass flip driving unit and two grass flipping wheels, and the grass flipping frames are mounted on the machine frame; the furrow openers are arranged on the machine frame or the grass flipping frames; the two grass flipping wheels are respectively and rotatably mounted on each grass flipping frame and respectively positioned on both sides in front of each furrow opener; the lateral sides of the two grass flipping wheels and the corresponding furrow opener have vertical included angles, the lower ends of the two grass flipping wheels are close to each other, and the upper ends of the two grass flipping wheels keep away from each other and form a V shape of which the opening faces upwards; each grass flip driving unit is mounted on the corresponding grass flipping frame, the input end of each grass flip driving unit is connected with the gearbox, and the output end of each grass flip driving unit is connected with the two grass flipping wheels so as to drive the two grass flipping wheels to rotate. Due to the adoption of the obliquely arranged grass flipping wheels, straw self-planting belts can be taken to both sides of a planting belt; power driving is adopted, the rotating speed of the grass flipping wheels is high, the straw processing capability is high, and the anti-blocking effect is good.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a no-tillage anti-blocking device for an obliquely driven mowing wheel. Background technique [0002] Conservation tillage is an advanced agricultural farming method that implements no-low tillage on farmland and covers the surface with crop stalks and residues to reduce soil erosion and improve soil fertility and drought resistance. The key issue of conservation tillage technology is to develop suitable no-tillage seeding equipment. The main problem of no-tillage seeders for wheat and corn in double-cropping areas in North China is the effect of the anti-blocking device, that is, the effect of the device for treating straw and root stubble. At present, domestic no-tillage anti-blocking devices mainly include passive anti-blocking devices and power-driven anti-blocking devices. The no-tillage anti-blocking device mainly processes straw by cutting, throwing, and dialing. T...

Problems solved by technology

[0003] Chinese patent announcement CN 2347348Y discloses a gear-tooth anti-blocking device for no-tillage mulching seeders, which is a passive anti-blocking device. Rotate to move the straw and stubble to both sides of the seed belt. The rotation speed of the mowing wheel is low, and the ability to handle straw and stubble is limited. It is only suitable for the situation where the amount of straw coverage on the ground is small.

When the stalks are within the range of straw removal and are on the non-seeding belt, the high-speed rotating weeding wheel will sweep the straw and stubble to the seed belt, which will aggravate the clogging of the opener
