Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an offset rotary tiller. Background Technology

[0002] Rotary tillers are a common plowing device used in agriculture to break up soil. They are mounted on the back of agricultural tractors. In practice, small agricultural vehicles are often used in complex terrains, such as cultivating near tree trunks in orchards, working on the edge of terraced fields, or cultivating on slopes (15°). When the rotary tiller is in use, it is always located directly behind the tractor. This means that the small agricultural vehicle has to avoid certain areas, such as near tree trunks or the edge of terraced fields, which can create large areas that cannot be cultivated due to the vehicle's movement, thus affecting the actual agricultural needs. Utility Model Content

[0003] The purpose of this invention is to provide an offset rotary tiller that solves the technical problem in the prior art where tilling is impossible over a large area near obstacles.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] A specific embodiment of this utility model provides an offset rotary tiller, combined with an attached... Figure 1 As shown, it mainly includes a connecting component, a rotary tiller component, and a first hydraulic cylinder 11. The connecting component and the rotary tiller component are hinged together, allowing the rotary tiller component to shift left and right relative to the connecting component. It should be noted that this left and right shift refers to the horizontal shift. In actual installation, the connecting component is connected to a small agricultural vehicle, and the rotary tiller component shifts relative to the small agricultural vehicle, causing it to shift to the rear of the small agricultural vehicle. This allows it to be closer to obstacles during actual tillage, greatly reducing untillable areas. The first hydraulic cylinder 11 is also provided, with one end connected to the side wall of the connecting component and the other end connected to the side wall of the rotary tiller component. This allows for active driving of the shift through the first hydraulic cylinder 11, and it can also be used to fix the shifted state after the shift is achieved, thus completing the tillage.

[0019] In a specific embodiment of this application, the connecting component includes an offset frame welded part 4. The end of the offset frame welded part 4 facing the rotary tiller component is a horizontal U-shaped end, that is, the two plates are arranged horizontally and parallel. The end of the offset frame welded part 4 facing the connecting component is a vertical U-shaped end, that is, the two plates are arranged vertically and parallel. The rotary tiller component is hinged to the horizontal U-shaped end. This method can realize the offset of the rotary tiller component in the direction of the plate at the parallel horizontal U-shaped end.

[0020] In some embodiments, the connecting assembly further includes a fixed connecting plate 1, connecting rods 2, and a second hydraulic cylinder 3. The fixed connecting plate 1 is U-shaped and opposite to the vertical U-shaped end. The two ends of the connecting rod 2 are respectively hinged to the fixed connecting plate 1 and the vertical U-shaped end. There can be four connecting rods 2, arranged in pairs between the fixed connecting plate 1 and the vertical U-shaped end. The four hinge points of the two connecting rods 2 located on the same side plate of the fixed connecting plate 1 and the vertical U-shaped end form a parallelogram. A second hydraulic cylinder 3 is also provided. One end of the second hydraulic cylinder 3 is hinged to the fixed connecting plate 1, and the other end is hinged to the vertical U-shaped end. Since the fixed connecting plate 1 is the part connected to the small agricultural vehicle, the second hydraulic cylinder 3 is used to drive the offset frame welded part 4 and the rotary tiller assembly to rise and fall as a whole. When tilling is not being carried out, the rotary tiller assembly can be raised by the second hydraulic cylinder 3, and when tilling is required, it can be lowered by the second hydraulic cylinder 3.

[0021] In some embodiments, the rotary tillage assembly includes a mounting frame 7, a motor mounting position 12, a pulley 6, a V-belt 5, and a blade 8. One end of the mounting frame 7 is hinged to a connecting assembly, and a first hydraulic cylinder 11 is hinged to the mounting frame 7. The motor mounting position 12 and the pulley 6 are both mounted on the mounting frame 7. A drive pulley 6 is positioned below the motor mounting position 12, and the motor is mounted on the motor mounting position 12 and connected to the drive pulley. A V-belt 5 is positioned between the drive pulley and the pulley 6. A blade 8 is positioned at the bottom of the mounting frame 7 and connected to the pulley 6. This allows the motor to be mounted on the motor mounting position 12 and connected to the drive pulley. The motor can then drive the drive pulley to rotate, which in turn drives the pulley 6 to rotate, thereby rotating the blade 8 mounted on the pulley 6 and achieving rotary tillage. The number of pulleys 6 is at least two, allowing the number to be adjusted according to actual needs to ensure more efficient tillage.

[0022] In some embodiments, the rotary tillage assembly further includes a hinge frame 13, a pressure roller 9, and an adjusting bolt 10. One end of the hinge frame 13 is hinged to the mounting frame 7, and the other end is provided with a pressure roller 9. The pressure roller 9 is located on one side of the V-belt 5. The adjusting bolt 10 is mounted on the mounting frame 7 via a bracket. The adjusting bolt 10 is located on the side of the pressure roller 9 away from the V-belt 5. The adjusting bolt 10 can press against the mounting frame 7, so the pressure force of the pressure roller 9 pressing against the V-belt 5 can be adjusted by adjusting the length of the adjusting bolt 10.
