TECHNICAL FIELD

[0001] The utility model relates to ploughing and smoothing device technical field, specifically, relates to a ploughing and smoothing device. BACKGROUND

[0002] The ploughing and smoothing device is a kind of agricultural machinery, and it is used to plough and smooth soil. It turns over and breaks soil by rotating ploughing and smoothing wheel, so that the soil becomes loose and uniform, and prepares for sowing or planting crops.

[0003] The working of the existing ploughing and smoothing device is as follows: the ploughing and smoothing device is connected to a tractor or other traction vehicle, and the ploughing and smoothing device is moved in the field by the traction vehicle. When moving in the field, the soil passing through is turned over and broken by rotating blades, so as to create good soil for cultivation.

[0004] Although this can achieve the loosening of soil, there are still the following problems: since the rotating blades are rotated by being fixed on rotating shafts, the spacing between adjacent rotating blades is difficult to adjust. Different crops require different soil tightness and water content, and only one spacing of rotating blades cannot meet the requirements of different crops. UTILITY MODEL CONTENTS

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 2 to 5 As shown, this embodiment provides a tillage device comprising a fixed frame 2. A tractor 1 is connected to one upper end of the fixed frame 2. A rotating shaft 51 is rotatably mounted on the fixed frame 2 to facilitate rotation of the fixed frame 2 away from the ground, facilitating movement of the tractor 1. Several tillage wheels 6 are slidably mounted on the rotating shaft 51, and several cutting blades 61 are fixedly mounted on the outer circumference of the tillage wheels 6. A spacing adjustment mechanism is provided on the fixed frame 2 to adjust the spacing between the tillage wheels 6.

[0028] The distance adjustment mechanism in this embodiment includes a distance adjustment plate 7 with first and second sliding grooves 22 and 23 disposed on either side of the fixed frame 2. Both the first and second sliding grooves 22 and 23 have a "convex" cross-section, restricting the sliding movement of the distance adjustment plate 7 and preventing it from slipping or misaligning. The distance adjustment plate 7 is slidably connected to both the first and second sliding grooves 22 and 23. Connectors 63 are rotatably mounted on each tilling wheel 6 to adjust the spacing between the tilling wheels 6 and facilitate their rotation. Several distance adjustment grooves 71 are provided on the distance adjustment plate 7, corresponding one to each connector 63 and slidably connected to each other. In this embodiment, the distance between each connector 63 is adjustable by sliding the connectors 63 within the grooves 71, thereby adjusting the spacing between the tilling wheels 6. This allows for adaptability to the moisture content and soil tightness requirements of different fields and crops.

[0029] In this embodiment, the screw rod 41 is rotatably mounted within the fixed frame 2. The first drive motor 4 is fixedly mounted on the fixed frame 2. The output shaft of the first drive motor 4 is fixedly connected to the screw rod 41. The connecting plate 72 is fixedly mounted on the pitch-adjusting plate 7, and the screw rod 41 and the connecting plate 72 are threadedly connected. Because the rotational travel of the screw rod 41 is much greater than the travel of the pitch-adjusting plate 7, the sliding position of the pitch-adjusting plate 7 on the fixed frame 2 can be controlled more accurately and reliably by rotating the screw rod 41. The first drive motor 4 used in this embodiment is a two-phase motor, which facilitates the adjustment of the forward and reverse rotation of the screw rod 41.

[0030] The positioning key 511 in this embodiment is fixedly mounted on the rotating shaft 51 to ensure that the tilling wheel 6 can be driven to rotate when the rotating shaft 51 rotates. The second drive motor 5 is fixedly mounted on the fixed frame 2, and the output shaft of the second drive motor 5 is fixedly connected to the rotating shaft 51. Each tilling wheel 6 is slidingly connected to the positioning key 511 to prevent the tilling wheel 6 from slipping or deviating from its position. The sliding sleeve 62 is fixedly mounted on the tilling wheel 6, and the rotating groove 621 is disposed on the sliding sleeve 62. The connecting member 63 includes a rotating ring 631, and the rotating groove 621 is rotatably connected to the connecting ring to prevent the connecting member 63 from rotating or deviating from its position. The sliding rod 632 is fixedly mounted on the rotating ring 631, and the sliding rod 632 is slidingly connected to the distance adjustment groove 71. This design is to ensure that the second drive motor 5 can drive the tilling wheel 6 to rotate on the basis of the adjustable spacing between the tilling wheels 6.

[0031] In this embodiment, the movable wheels 21 are rotatably mounted on either side of the fixed frame 2. The distance between the fixed frame 2 and the farthest end of the movable wheels 21 is greater than the farthest distance between the fixed frame 2 and the tilling wheel 6. This design ensures that during tillage, the movable wheels 21 contact the soil surface, reducing friction generated by the movement of the fixed frame 2 and the soil, facilitating the movement of the fixed frame 2. At this time, the tilling wheel 6 is embedded in the soil, loosening it. A cushioning layer 211 made of rubber is also fixed to the outer periphery of the movable wheels 21. This design reduces wear and tear caused by collision between the movable wheels 21 and the soil when the telescopic member 3 is extended.

[0032] In this embodiment, the upper end of the fixed frame 2 is further provided with a telescopic member 3. The fixed end of the telescopic member 3 is rotatably connected to the fixed frame 2, and the telescopic end of the telescopic member 3 is rotatably connected to the tractor 1. The fixed frame 2 and the tractor 1 are rotatably connected. The telescopic member 3 used in this embodiment is preferably a hydraulic cylinder or a pneumatic cylinder. These hydraulic cylinders and pneumatic cylinders are both conventional and will not be described in detail in this embodiment. This design allows the fixed frame 2 to be moved away from the soil by retracting the telescopic member 3, facilitating the movement of the tractor 1. The fixed frame 2 can then be brought into contact with the soil by extending the telescopic member 3, completing the tillage work.

[0033] In this embodiment, the spacing between the adjustable slots 71 is uniform to ensure more uniform soil tillage by the tilling wheel 6. The spacing between adjacent adjustable slots 71 on the side closer to the first drive motor 4 is smaller than the spacing between adjacent adjustable slots 71 on the side farther from the first drive motor 4. The different spacing between adjacent adjustable slots 71 on both sides ensures that the spacing between the tilling wheels 6 can be adjusted during movement of the adjustable plate 7.

[0034] The working process of this embodiment is as follows: when the spacing of the tilling wheels 6 on the tilling device needs to be adjusted, the first drive motor 4 is started to drive the lead screw to rotate, causing the distance adjustment plate 7 to slide in the sliding groove, driving the sliding rod 632 to slide in the distance adjustment groove 71 until the spacing between adjacent distance adjustment rods reaches the appropriate value. The first drive motor 4 is then turned off. The second drive motor 5 is then started and the telescopic member 3 is extended, so that the tilling wheels 6 and the moving wheel 21 contact the soil. The tractor 1 is then moved to achieve soil tillage.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
