Straw-pressing expansion-cutting type active no-tillage anti-blocking device

Abstract

The invention belongs to the technical field of agricultural machinery, and relates to a straw-pressing expansion-cutting type active no-tillage anti-blocking device. A power cutter device and a straw pressing device are coaxially and horizontally disposed below a frame I, rotational radius of each cutter is smaller than radius of a guard and larger than radius of each arc straw-pressing board, and a gearbox transmits power to the power cutter device. The straw-pressing expansion-cutting type active no-tillage anti-blocking device, fertilizing ditchers, a seed-fertilizer box and seeding compaction mechanisms form a no-tillage seeding machine, wherein the fertilizing devices, the seed-fertilizer box and the seeding compaction mechanisms are disposed on a frame II. During operation, the cutters of the power cutter device rotate in gaps among the arc straw-pressing boards, the front end of each cutter in the area of the arc straw-pressing boards extends out of the straw pressing device from the corresponding gap between the arc straw-pressing boards, the cutters in the area of the guard contract into the straw pressing device, the arc straw-pressing boards contact with land to press straws so as to assist the power cutting device in cutting the straws and root stubbles when the straw pressing device slides forward, and accordingly blocking of a ditching device behind is prevented. The straw-pressing expansion-cutting type active no-tillage anti-blocking device is low in soil interference, low in power consumption, simple in structure and applicable to wheat and corn seeding.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an active no-tillage anti-blocking device for pressing grass, stretching and cutting. Background technique [0002] Conservation tillage is an advanced agricultural farming method that implements no-tillage on farmland and uses crop stalks to cover the surface to reduce soil wind and water erosion and improve soil fertility and drought resistance. At present, the core problem of conservation tillage technology is the blockage of no-tillage planters caused by the large amount of straw coverage. Therefore, it is of great significance to develop anti-blocking devices for planters suitable for conservation tillage techniques. At present, there are mainly two types of anti-blocking devices for no-tillage seeders in my country: passive anti-blocking devices and power-driven anti-blocking devices. [0003] The grass wheel anti-blocking device in the patent No...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problems described in the background technology that the straw and stubble can be pressed down to provide support for power cutting, and at the same time prevent the straw and stubble from falling on the seed belt after being cut and thrown, so as to keep the seed belt clean and avoid The front of the opener is blocked, fertilization and seeding are successfully completed, and the quality of sowing is improved. A grass-pressing telescopic cutting active no-tillage anti-blocking device is provided, which is characterized in that the grass-pressing telescopic cutting active no-tillage anti-blocking device is suspended by three points 1. Gear box 2, frame I3, side plate 10, power cutter device 4 and grass pressing device 11. Rectangular frame I3 consists of frame I front plate 3002, frame I rear plate 3003 and frame I top plate Composed of 3004, the left and right side plates 10 are respectively fixed on the left and right ends of the frame I3, the gearbox 2 is fixed on the frame I3 and the top plate 3004 of the frame I, and the gearbox input shaft 2001 of the gearbox 2 passes forward The universal joint is connected with the power output shaft of the tractor. The transmission output shaft 2004 of the gearbox 2 is parallel to the cutter shaft 4001 of the power cutter device 4. The power transmission mechanism inside the gearbox 2 transmits the power to the cutter shaft 4001. Three points The vertical tie rod and diagonal tie rod of the suspension 1 are fixedly connected with the front plate 3002 of the frame I and the top of the gearbox 2 respectively, the three-point suspension 1 is connected with the tractor traction device with pins, and the power cutter device 4 and the grass pressing device 11 are coaxial Placed horizontally under rack I3;
