Corn stalk cutting and laying device

Abstract

The invention provides a corn stalk chopping and laying device, which includes a housing, an auger installed in the housing through a bearing, and a chopping tool, wherein two blades on the auger shaft are installed symmetrically inward from the end of the auger , and there is a distance between the ends of the two blades near the center of the auger shaft, and it is characterized in that: the chopping knives include a plurality of first chopping knives and a plurality of second chopping knives, wherein the plurality of first chopping knives are uniform and The direction is symmetrically installed on the two blades, and along the rotation track of the blades, the two adjacent first cutting knives overlap, and each blade is at an angle of 5 to 10 degrees to the axis of the auger; multiple second cutting knives The crushing knife is evenly and symmetrically installed on the auger shaft located in the middle of the two blades, and each blade with a symmetrical direction passes through the center of the auger shaft, and is at an angle of 5 to 10 degrees with the auger axis; The rotation trajectories of the two inner first shredding knives overlap with the rotation trajectories of the adjacent second shredding knives. The chopping cutter of the present invention is directly installed on the auger, has compact structure and excellent working performance.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a corn stalk chopping and laying device, which is suitable for use with a corn harvester. technical background [0002] At present, most of the corn stalks in our country are processed by crushing and returning to the field or silage, which not only consumes a lot of power, but also wastes straw resources. Then the auger is concentrated into strips and laid on the ground. The design of the equipment is complicated and the power consumption is large. In order to simplify the structure of the machine and solve the shortcomings of the existing straw laying device, it is very necessary to develop a new type of corn straw laying device. SUMMARY OF THE INVENTION [0003] The invention is a corn stalk chopping and laying device with simple structure, high working efficiency and excellent working performance. Its technical solutions are: [0004] A corn stalk chopping and layin...
