Embodiment Construction
[0028] The present invention is described below in conjunction with accompanying drawing.
[0029] Such as figure 1 and figure 2 As shown, the present invention consists of a subsoiler A and a stubble cutting device B. The subsoiler A is composed of a frame I, a suspension device II and a subsoiler III, wherein the frame I consists of a left longitudinal beam 1, a front Beam 2, middle beam I3, middle beam II4, right longitudinal beam 5 and rear beam 6; The two ends of the rear beam 6 are respectively fixed on the inside of the left longitudinal beam 1 and the right longitudinal beam 6, forming a "mesh" shape; the suspension device II is located at the front of the front beam 2 of the frame I, and the subsoiling device III is located at the rear beam 6 of the frame I middle.
[0030] Such as image 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the stubble cutting device B is composed of a connecting frame C, a stubble cutting tool handle D, a stubble cut...

The invention relates to a stubble cutting device for deep scarification operation and belongs to the technical field of agricultural machinery. A stubble cutting device body is located in the middleof a middle beam I, and a stubble cutting blade of the stubble cutting device body and a deep scarification device are in the same straight line; a front hole III of a leaf spring of the stubble cutting device body is movably connected with a mounting frame, a rear hole III of the leaf spring is movably connected with an upper groove of a connector, and the left end of a front knife handle is movably connected with the mounting frame; the middle of a knife handle body is fixedly connected with a lower groove of the connector, and the stubble cutting blade is fixed to the tail end of a rear front knife handle. The designed stubble cutting designed for the deep scarification operation can achieve an automatic protection effect when encountering hard objects, the designed stubble cutting blade can be conveniently exchanged and used, and the service life of the stubble cutting blade is greatly prolonged. The device can cut straw in front of a deep scarification shovel and break topsoil infront of the deep scarification shovel. Therefore, a clogging problem during the scarification operation can be solved, and the tillage resistance of the scarification operation can be reduced at thesame time.
Description
technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a stubble cutting device for subsoiling operations. Background technique [0002] With the development of conservation tillage, the application of straw returning and less-tillage and no-tillage is more and more widely used, and as an important part of conservation tillage——subsoiling operation has also been paid more and more attention by people. Under the premise of buckling the soil and not disturbing the soil layer, the bottom layer of the plow is broken. The breaking of the bottom layer of the plow is conducive to the penetration of the root system of the crops into the deep soil, absorbing the moisture and nutrients of the deep soil, and is also conducive to the infiltration of rainwater. Therefore, subsoiling is of great significance for crop yield increase, surface runoff reduction and soil moisture conservation. [0003] Since the surface of t...
