Problems solved by technology
There are defects such as poor stability of the overall structure of the plow frame and complex structure
[0003] For example, the existing hydraulic tilting plow amplitude modulation method adopts a gear structure and a semi-circular plate welded cantilever small shaft structure. The former has high manufacturing costs and complex structure, while the latter cantilever small shaft is easy to break, unreliable work, and high maintenance costs.

A breadth-adjusting hydraulic turnover plow comprises a plow frame, a plow body assembly, a breadth-adjusting device, a suspension assembly and a hydraulic oil cylinder. The hydraulic oil cylinder is fixedly connected with the plow frame and the suspension assembly, and the plow body assembly is installed on the plow frame through the breadth-adjusting device. The plow frame comprises a cuboid-shaped girder, one end of the girder is fixedly connected with the hydraulic oil cylinder and the suspension assembly, a circle center location hole and a breadth-adjusting arc-shaped lead hole are arranged at the positions of the breadth-adjusting device contacted with the upper surface and the lower surface of the girder, the upper surface and the lower surface of the girder are both provided with a pair of fixed screw holes, an arranging direction of two fixed screw holes in each pair of fixed screw holes is the same as an extension direction of the girder, one pair of fixed screw holes on each surface of the girder is just opposite to the circle center location hole and a breadth-adjusting lead hole, the breadth-adjusting device and the girder are relatively fixed in a bolt fixing mode, and the breadth-adjusting device can move along an arc-shaped track provided by the breadth-adjusting arc-shaped lead hole with the circle center location hole serving as the center so as to achieve breadth adjustment of the plow body assembly.
Description
Technical field: [0001] The invention relates to the technical field of agricultural machinery, in particular to an amplitude-modulated hydraulic turning plow and an amplitude-modulating device for changing the width of the turning plow. Background technique: [0002] The amplitude modulation mode of the existing hydraulic overturning plow is: the overall displacement mode of the plow frame realizes the adjustment. There are defects such as poor stability of the overall structure of the plow frame and complicated structure. [0003] For example, the existing hydraulic tilting plow amplitude modulation method adopts a gear structure and a semi-circular plate welded cantilever small shaft structure. The former has high manufacturing costs and a complicated structure, while the latter cantilever small shaft is easy to break, unreliable in operation, and expensive to use and maintain. Invention content: [0004] In view of this, it is necessary to provide an amplitude modulat...
