Description

Technical Field

[0001] The utility model relates to a tillage width adjusting mechanism, in particular to a tillage width adjusting device for a rotary tillage and soil preparation machine, belonging to the technical field of rotary tillage and soil preparation machines. Background Art

[0002] In the prior art, as disclosed in the utility model with the application number 202222274380.0, a combined soil preparation machine for medicinal material planting is disclosed. In order to solve the problem that since different medicinal materials are suitable for growing in different soil environments, the suitable planting depths are also different, but the existing combined soil preparation machine cannot adjust the depth of rotary tillage planting. Therefore, different combined soil preparation machines are required for different medicinal material plantings, which reduces the applicability of the combined soil preparation machine. Through a driving motor and a cross bar, the rotary tillage blades can be driven to rotate, and the rotary tillage blades can till the soil; through a double-shaft motor and a rotating rod, a first bevel gear can be driven to rotate. The first bevel gear can drive a threaded rod to rotate through a second bevel gear and a vertical rod. The threaded rod can drive a fixed block to move downward through a threaded sleeve and an L-shaped connecting rod, and the fixed block can drive the rotary tillage blade to move downward to adjust the height of the rotary tillage blade, so as to adjust the depth of rotary tillage planting, so that the device is suitable for the planting of various medicinal materials, and thus the applicability of the device is improved.

[0003] The current situation similar to the above application still has deficiencies:

[0004] During the use of the existing rotary tillage and soil preparation machines, a tractor is mostly used as the power source. However, the above device uses an electric drive method that requires an external power source, and traditional tractors cannot be installed and used, resulting in low applicability; <{

[0005] Therefore, a tillage width adjusting device for a rotary tillage and soil preparation machine is designed to optimize the above problems. Content of the Utility Model

The rotation operation of the rotary tillage blades on the mounting shaft is controlled by a gear transmission method, and arc-shaped sliding grooves are symmetrically arranged on both sides of the machine frame. A slider is slidably arranged inside the arc-shaped sliding groove, and a mounting rod passes through the slider and is rotatably connected to the slider. By controlling the slider to slide inside the arc-shaped sliding groove, the horizontal height of the mounting rod can be changed, thereby regulating the tillage width during operation. In addition, the second sub-gear rotates around the first sub-gear and always remains in a meshing state to ensure the stable operation of the transmission.
