Further, the plowshare device includes a plow body, a grass-pressing device and a grass-covering board; the arrangement of the plow body adopts a design with a longitudinal arrangement angle of 40°, a grass-pressing device is arranged in front of the plow body, and a grass-covering board is arranged at the upper end of the plow body to improve the machine tools. Cover stubble ability.

Further, the suppressing wheel assembly is composed of a suppressing wheel, a floating connecting rod, and a spring; the suppressing wheel and the floating connecting rod are welded and fixed, and the entire suppressing wheel assembly is hinged to the frame through the floating connecting rod, and a compression spring is installed on the floating connecting rod.

Further, the whole machine is connected with the three-point suspension device of the agricultural tractor through the suspension frame, and is pulled by the tractor.

The utility model has the following beneficial effects:

The beneficial effects of the utility model are: the utility model has the advantages of compact structure, reliable operation, high operation efficiency, good straw burying effect, effectively overcomes the adverse effects brought by single operation procedures, and realizes the coordination and continuity of various mechanisms and working parts according to operation procedures and processes The action greatly reduces the labor intensity of farmers, and achieves the purpose of comprehensively improving operating efficiency, reducing costs, and increasing and stabilizing production. It can be widely used in compound operations in dry fields.
