Agricultural tool profiling device

Abstract

The invention relates to an agricultural tool profiling device. The agricultural machine profiling device comprises a suspension frame, a left profiling frame, a right profiling frame, a left profiling driving structure, a right profiling driving structure and a machine frame; the suspension frame is fixedly connected with a tractor; the machine frame is used for installing agricultural tools; thefront end of the left profiling frame and the front end of the right profiling frame are installed at the rear end of the suspension frame; the lower end of the left profiling frame and the lower endof the right profiling frame are rotationally connected with the frame; the upper end of the left profiling driving structure and the upper end of the right profiling driving structure are rotationally connected with the rear upper end of the suspension frame, and the lower end of the left profiling driving structure and the lower end of the right profiling driving structure are rotationally connected with the upper surface of the machine frame; and when the left profiling driving structure and the right profiling driving structure work, the left profiling frame and the right profiling framecan move relative to the suspension frame. Through the control of synchronous or asynchronous movement of the left profiling driving structure and the right profiling driving structure, the left profiling frame and the right profiling frame synchronously move relative to the suspension frame, so that vertical profiling of the machine frame can be realized, or the lower end of the left profiling frame and the lower end of the right profiling frame can rotate relative to the machine frame, so that the transverse inclination angle of the machine frame can be changed, so that horizontal profilingof the machine frame is realized. The problems that agricultural tools are suspended and mud is blocked during hole digging in a mud surface due to the fact that the mud bottom and the mud surface arenot flat is avoided, and operation quality is prevented from being influenced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an agricultural implement profiling device. Background technique [0002] During the field operation of agricultural machinery and tools, most of the agricultural machinery and tools need to have a leveling mechanism, especially for paddy rice direct seeding machines and paddy field levelers; for direct seeding machines, the power chassis will tilt left and right due to uneven paddy field mud feet. Floating up and down, it is required that the working tools have horizontal and vertical profiling functions, otherwise potholes will easily appear on the mud surface and affect the quality of planting; for graders, no matter how the mud foot changes, it is hoped that the grader can work on the same plane. Otherwise, it will affect the leveling effect; and the current three-point suspension device of wheeled tractor does not have the function of synchronous horizontal an...

[0002] During the field operation of agricultural machinery and tools, most of the agricultural machinery and tools need to have a leveling mechanism, especially for paddy rice direct seeding machines and paddy field levelers; for direct seeding machines, the power chassis will tilt left and right due to uneven paddy field mud feet. Floating up and down, it is required that the working tools have horizontal and vertical profiling functions, otherwise potholes will easily appear on the mud surface and affect the quality of planting; for graders, no matter how the mud foot changes, it is hoped that the grader can work on the same plane. Otherwise, it will affect the leveling effect; and the current three-point suspension device of wheeled tractor does not have the function of synchronous horizontal and vertical forced profiling, which makes the operation quality of the machine tool poor and restricts the development of agricultural modernization and intelligence
