Description
Technical Field
The utility model belongs to agricultural machinery, and mainly relates to a vertical type movable and fixed cutter combined stubble cleaning device.
Background
The stubble returning is used as one of core contents of protective farming technologies, improves soil conditions, improves crop yield, plays an important role in soil organic matter preservation and environmental protection, but the traditional horizontal stubble cleaning device or disc harrow and other soil preparation machines have the problems of large unit power consumption and soil movement amount, soil moisture loss and weathering erosion after operation and the like, and can not simultaneously crush stubble and underground main roots.
Disclosure of Invention
The utility model aims to solve the problems, and designs a vertical movable and fixed cutter combined stubble cleaning device which can simultaneously crush overground stubble and underground main roots.
The purpose of the utility model is realized as follows: a vertical type movable and fixed cutter combined stubble cleaning device comprises a rack (2), a three-point suspension bracket (1) and a speed reducer (3), and is characterized in that the speed reducer (3) and the three-point suspension bracket (1) are sequentially fixed above the middle of the rack (2), a universal transmission shaft (11) is connected in front of the speed reducer (3), and the universal transmission shaft (11) is connected with a power output shaft of a tractor; an output shaft at the lower part of the speed reducer (3) is fixed with a stubble-removing cutter shaft (9) through a pin shaft (10); five stubble-cleaning movable cutters (8) are welded on the stubble-cleaning cutter shaft (9) from top to bottom at an interval angle of 72 degrees along the spiral line, and two stubble-cleaning cutters (7) are welded on a disc at the lower part of the stubble-cleaning cutter shaft (9) at an interval angle of 180 degrees; a supporting rod (4) and a fixed cutter plate (5) are fixed at the left lower part of the frame (2), and five fixed cutters (6) are welded on the fixed cutter plate (5) according to the positions of the stubble-cleaning movable cutters (8). The root killing knife (7) is designed according to an Archimedes spiral line, the selected sliding cutting angle is 50 degrees, and the soil penetration depth is 50 millimeters. The interval between the stubble-cleaning movable knife (8) and the fixed knife (6) is 1 cm.
Compared with the prior art, the utility model has the beneficial effects that the utility model is a vertical type movable and fixed cutter combined stubble cleaning device, which mainly moves the ground residual stubble to the direction of the fixed cutter through the stubble cleaning movable cutters arranged along the spiral line at the upper part, and crushes the residual stubble under the matching of the stubble cleaning movable cutters and the fixed cutter; then the root removing knife at the lower part crushes the underground main roots, thereby reducing the soil disturbance amount and the machine power consumption during operation and improving the working efficiency.

Detailed Description
A vertical type movable and fixed cutter combined stubble cleaning device comprises a rack (2), a three-point suspension bracket (1) and a speed reducer (3), and is characterized in that the speed reducer (3) and the three-point suspension bracket (1) are sequentially fixed above the middle of the rack (2), a universal transmission shaft (11) is connected in front of the speed reducer (3), and the universal transmission shaft (11) is connected with a power output shaft of a tractor; an output shaft at the lower part of the speed reducer (3) is fixed with a stubble-removing cutter shaft (9) through a pin shaft (10); five stubble-cleaning movable cutters (8) are welded on the stubble-cleaning cutter shaft (9) from top to bottom at an interval angle of 72 degrees along the spiral line, and the stubble-cleaning cutters (7) are welded on a disc at the lower part of the stubble-cleaning cutter shaft (9) at an interval angle of 180 degrees; a supporting rod (4) and a fixed cutter plate (5) are fixed at the left lower part of the frame (2), and five fixed cutters (6) are welded on the fixed cutter plate (5) according to the positions of the stubble-cleaning movable cutters (8). The root killing knife (7) is designed according to an Archimedes spiral line, the selected sliding cutting angle is 50 degrees, and the soil penetration depth is 50 millimeters. The interval between the stubble-cleaning movable knife (8) and the fixed knife (6) is 1 cm.
The stubble cleaning device is connected with a tractor through a three-point suspension bracket (1), when the stubble cleaning device works, the tractor transmits power to a speed reducer (3) through a universal transmission shaft (11), an output shaft of the speed reducer (3) drives a stubble cleaning movable cutter (8) and a stubble cleaning cutter (7) on a stubble cleaning cutter shaft (9) to rotate, the stubble cleaning movable cutter (8) moves ground stubble toward a fixed cutter (6), and the stubble cleaning movable cutter (8) is matched with the fixed cutter (6) to crush the residual stubble; the root-removing knife (7) fixed on the disc at the lower part of the root-removing knife shaft (9) crushes the main roots at the lower part, thus finishing the single root-removing operation.
