Depth and spacing controllable subsoiler

Abstract

The invention discloses a depth and spacing controllable subsoiler. The subsoiler includes a frame, a subsoiler, a depth-limiting wheel, a connecting rod, and bolts; wherein the frame includes a front frame, an intermediate machine Frame, left-wing frame, right-wing frame; the subsoiling device includes a first subsoiling shovel and a second subsoiling shovel; the left and right sides of the front frame are provided with depth-limiting wheels, and A first subsoiling shovel is provided, and an intermediate frame is vertically arranged at the center of the rear side of the front frame, and first slots are symmetrically arranged on the rear sides of the front frame on both sides of the intermediate frame, and the left-wing machine The frame and the right-wing frame are plugged into the first slot through bolts, the bottom surface of the left-wing frame is provided with a plurality of second subsoiling shovels, and the inner side of the left-wing frame is provided with a second slot. One end of the connecting rod is inserted into the second slot through a bolt, and the other end of the connecting rod is connected with the middle frame through a bolt. The invention can adjust the depth and width of the subsoiling shovel, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of agricultural planting machinery, in particular to a depth and spacing controllable subsoiler. Background technique [0002] Mechanical subsoiling refers to the mechanized technology of using different power machinery to complete the subsoiling of farmland operations. The purpose of mechanical subsoiling is to loosen the soil, break the bottom of the plow, increase the speed and quantity of rainwater infiltration, and reduce runoff , to reduce water evaporation loss, because mechanical subsoiling only loosens the soil without turning over the soil, the soil in the plow layer will not be disturbed after operation, and the amount of soil movement is small, so it is especially suitable for soil with shallow black soil layer and unsuitable for plowing operations. The purpose of soil preparation It is to create a good soil structure and surface state, coordinate water, nutrients, air, heat and other factors, im...

AI Technical Summary

Problems solved by technology

The existing machinery is generally integrated with subsoiling and soil preparation, but most of the machinery is fixed and cannot be adjusted, which seriously affects the use of the machine for different ground conditions and reduces the scope of use of the machine. Therefore, we are committed to To study a freely adjustable deep loosening soil preparation technology with a wide range of applications to meet the needs of the society
