Description

Technical Field

[0001] The utility model relates to the technical field of micro-tillage machine cutters, in particular to a bionic cutter for a micro-tillage machine for hilly and mountainous areas. Background Art

[0002] The hilly mountain micro-tillage machine bionic tool is a micro-tillage machine tool designed specifically for hilly mountains. It combines the principles of bionics and simulates the form, structure or function of certain organisms in nature to improve the tillage efficiency and adaptability of the tool in complex terrain.

[0003] However, when the existing micro-tillage machine cutters are used for rotary tillage on hilly and mountainous areas, the cutters have simple and identical shapes, so each cutter has large resistance on the tangent surface when breaking the soil, and the cutters have poor cutting performance on crop roots during rotation, resulting in a general rotary tillage effect on the soil during operation, which affects the subsequent farming effect.

[0005] As an improvement of the above technical solution, the anti-winding structure includes a square column, a limiting slot, a gravity block and a V-shaped cutting tool. The square column is fixedly installed on the outside of the connecting shaft and is located on the clockwise side of the connecting base. The limiting slot is opened on the front side of the square column. The gravity block is movably connected to the inside of the limiting slot. The V-shaped cutting tool is fixedly installed on the clockwise side of the gravity block. The anti-winding structure is used to cut the entangled grass between adjacent rotary tillage tool structures during the movement.

[0006] As an improvement of the above technical solution, the clockwise side of the crushing tool body is designed in a V-shape, which reduces the resistance of the crushing tool body to soil crushing when it rotates.

[0007] As an improvement of the above technical solution, the length of the second ground-breaking tool is greater than that of the second ground-breaking tool, and the length of the third ground-breaking tool is greater than that of the second ground-breaking tool, so that the first ground-breaking tool, the second ground-breaking tool and the third ground-breaking tool can gradually and deeply crush the soil when they rotate synchronously.

[0010] The beneficial effects of the utility model are as follows: the rotary tillage tool structure gradually and deeply crushes the soil through changes in shape and size during rotation, thereby reducing the crushing resistance of each tool to the soil, and when grass is entangled between adjacent rotary tillage tool structures, the V-shaped cutting tool moves to cut the entangled grass due to its own gravity during rotation, which facilitates the rotation of the rotary tillage tool structure, thereby improving the rotary tillage effect of the micro-tillage machine's bionic tool on the soil.

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

The force block 52 is movably connected to the inside of the limiting slot 51, and the V-shaped cutting tool 53 is fixedly installed on the clockwise side of the gravity block 52. The side of the V-shaped cutting tool 53 close to the connecting shaft 1 is designed in an arc shape, which is convenient for the V-shaped cutting tool 53 to contact with the outer side of the connecting shaft 1 to cut the entangled grass when moving. The anti-entanglement structure is used to cut the entangled grass between adjacent rotary tillage tool structures during the movement. The rotary tillage tool structure includes a connecting base 4, a handle block 41, a crushing tool body 42, a first soil breaking tool 43, a second soil breaking tool 44 and a third soil breaking tool 45. The connecting base 4 is fixedly installed on the outer side of the connecting shaft 1 The handle block 41 is movably connected to the inner side of the connecting base 4, and the connecting base 4 and the handle block 41 are fixedly connected by a screw. The crushing tool body 42 is fixedly installed on the side of the handle block 41 away from the center of the circle. The clockwise side of the crushing tool body 42 is V-shaped, which reduces the resistance of the crushing tool body 42 to soil crushing during rotation. The first soil-breaking tool 43 is fixedly installed on the clockwise side of the crushing tool body 42 and is located near the center of the circle. The second soil-breaking tool 44 is fixedly installed on the clockwise side of the crushing tool body 42, and the second soil-breaking tool 44 is located on the side of the first soil-breaking tool 43 away from the center of the circle. The third soil-breaking tool 4 The first soil-breaking cutter 43, the second soil-breaking cutter 44 and the third soil-breaking cutter 45 are fixedly mounted on one side of the crushing cutter body 42 in a clockwise direction and are located away from the center of the circle. The length of the second soil-breaking cutter 44 is greater than that of the second soil-breaking cutter 44, and the length of the third soil-breaking cutter 45 is greater than that of the second soil-breaking cutter 44, so that the first soil-breaking cutter 43, the second soil-breaking cutter 44 and the third soil-breaking cutter 45 can gradually and deeply crush the soil when they rotate synchronously. The first soil-breaking cutter 43, the second soil-breaking cutter 44 and the third soil-breaking cutter 45 are all designed to be arc-shaped on one side close to the center of the circle, so that the first soil-breaking cutter 43, the second soil-breaking cutter 44 and the third soil-breaking cutter 45 can hook and cut the crop roots when they rotate.

[0017] When in use, the handle block 41 is clamped in the connecting base 4 and fixed by a screw, and then the connecting shaft 1 is clamped on the micro-tillage machine through the square connecting bin 2 and fixed by the connecting screw 3. The micro-tillage machine drives the connecting shaft 1 to rotate, the connecting shaft 1 drives the connecting base 4 to rotate, the connecting base 4 drives the handle block 41 to rotate, the handle block 41 drives the crushing tool body 42 to rotate, and the crushing tool body 42 drives the first soil-breaking tool 43, the second soil-breaking tool 44 and the third soil-breaking tool 45 to rotate. The crushing tool body 42 rotates synchronously to crush the soil, and the first soil-breaking tool 43, the second soil-breaking tool 44 and the third soil-breaking tool 45 gradually and deeply crush the soil while rotating synchronously. Since the crushing tool body 42, the first soil-breaking tool 43, the second soil-breaking tool 44 and the third soil-breaking tool 45 are all designed as arc shapes, the crushing resistance of each tool to the soil is reduced through the changes in shape and size, and the energy consumption of the rotary tillage condition of the micro-tillage machine is reduced at the same time. The number of tools inside the adjacent rotary tillage tool structures on the same horizontal plane is different. The stress of the rotary tillage tool structure when breaking the soil is reduced. Since the first soil-breaking tool 43 is designed in an arc shape, the first soil-breaking tool 43 hooks up the crop roots for cutting during the rotation. Similarly, the working principles of the second soil-breaking tool 44 and the third soil-breaking tool 45 are the same as above. The first soil-breaking tool 43, the second soil-breaking tool 44 and the third soil-breaking tool 45 hook up the crop roots for cutting, thereby improving the cutting effect on the crop roots. At the same time, the connecting shaft 1 drives the limiting slot 51 to rotate, and the limiting slot 51 drives the gravity block 52 to rotate. The gravity The block 52 drives the V-shaped cutting tool 53 to rotate. During the rotation of the V-shaped cutting tool 53, the centrifugal force is less than the total gravity of the gravity block 52 and the V-shaped cutting tool 53, so that the V-shaped cutting tool 53 moves along the limiting slot 51 through the gravity block 52 during the rotation. During the movement, the V-shaped cutting tool 53 circulates between approaching the center of the circle and moving away from the center of the circle, so that the V-shaped cutting tool 53 cuts the grass wrapped between adjacent connecting bases 4 when moving, thereby preventing the grass from affecting the subsequent operation of the micro-tillage machine.

[0018] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
