Description

Technical Field

[0001] This utility model relates to the field of agricultural tillage machinery technology, specifically to a circular roller-type soil crushing roller device. Background Technology

[0002] Soil-crushing rollers are key components in agricultural tillage operations, primarily used to break up large clods of soil after plowing and level the soil, creating favorable soil conditions for sowing and crop growth. Existing soil-crushing roller devices have the following shortcomings in practical applications: Traditional soil-crushing rollers mostly use straight-line or simple strip structures, which have limited ability to crush large soil clods, easily resulting in uneven soil crushing. Some stubborn soil clods cannot be effectively crushed, affecting the quality of subsequent sowing. The soil-penetration depth adjustment of the soil-crushing rollers mostly relies on manual disassembly of shims or bolts for adjustment, which is cumbersome and has low precision. It cannot be quickly adapted to soil hardness and crop needs, resulting in poor adaptability. The connection structure between the soil-crushing roller and the rake frame is prone to loosening due to vibration. After long-term operation, it may shift, affecting the flatness of the crushed soil and even causing component damage. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a circular roller soil crushing roller device with excellent soil crushing effect, convenient height adjustment, stable connection and robust structure.

[0004] The technical solution adopted by this utility model is as follows: This utility model provides a circular roller-type soil crushing roller device, including a novel soil crushing roller, an adjusting screw assembly, and a rake frame connecting beam. The novel soil crushing roller is mounted on the adjusting screw assembly, which is mounted on the rake frame connecting beam for adjusting the height of the novel soil crushing roller. The novel soil crushing roller includes a soil crushing roller frame beam, side plates, end plates, circular tubes, and intermediate plates. The soil crushing roller frame beam is mounted on the adjusting screw assembly. Two sets of side plates are provided, with the two sets of side plates respectively mounted at both ends of the soil crushing roller frame beam. Two sets of end plates are provided, with the two sets of end plates rotatably mounted on the side plates at both ends via bearings. The circular tube is welded between the two sets of end plates and is arranged in a spiral shape. Several sets of circular tubes are arranged in a circular array along the circumference of the end plates. Several sets of intermediate plates are evenly spaced between the two sets of end plates. The circular tube is welded to the intermediate plates.

[0005] Preferably, the adjusting screw assembly includes a soil-crushing roller connecting beam, an adjusting sleeve, a left-hand nut, a right-hand nut, a left-hand adjusting screw, and a right-hand adjusting screw. A soil-crushing roller connecting plate is welded onto the rake frame connecting beam, and the soil-crushing roller connecting beam is rotatably mounted on the soil-crushing roller connecting plate. The soil-crushing roller frame crossbeam is fixed to the soil-crushing roller connecting beam. The left-hand nut and the right-hand nut are respectively welded to the left and right sides of the adjusting sleeve. The left-hand adjusting screw is threaded into the left-hand nut and hinged to the soil-crushing roller connecting plate. A connecting beam ear plate is provided on the soil-crushing roller connecting beam. The right-hand adjusting screw is threaded into the right-hand nut and hinged to the connecting beam ear plate.

[0006] Preferably, a first V-shaped clamping plate is welded to the end of the soil crushing roller connecting beam, and a second V-shaped clamping plate that matches the first V-shaped clamping plate is bolted to the first V-shaped clamping plate.

[0008] More preferably, a roller frame reinforcing rib is welded between the crossbeam and the side plate of the soil crushing roller frame, and the roller frame reinforcing rib is L-shaped.

[0009] More preferably, the end plate is provided with plate reinforcing ribs, and the plate reinforcing ribs are arranged in a ring array of four groups.

[0010] More preferably, the adjusting sleeve is provided with an adjusting hole.

[0011] More preferably, the connecting beam ear plate is welded to the soil crushing roller connecting beam.

[0012] The beneficial effects of this utility model by adopting the above structure are as follows: With its simple structure, the spirally distributed circular tubes form a continuous cutting edge, which can effectively buffer the impact of hard objects such as stones and extend the service life of the equipment.

[0013] It is highly efficient and powerful. Through the rotation of the round tube and friction with the soil, it can break up soil clods more finely. It is suitable for fine land preparation before crop sowing, and is especially effective for clay soils. It can reduce soil clumping and improve sowing uniformity.

[0014] It is reliable in operation, with a smooth cylindrical surface and adjustable pressure via a lead screw. In damp soil, it prevents clay adhesion; when operating on slopes, the counterweight adjustment prevents the machine from slipping. This enhances safety to a certain extent.

[0023] like Figures 1-6 As shown, this utility model discloses a circular roller type soil crushing roller device, including a novel soil crushing roller 1, an adjusting screw assembly 2, and a rake frame connecting beam 3. The novel soil crushing roller 1 is mounted on the adjusting screw assembly 2, and the adjusting screw assembly 2 is mounted on the rake frame connecting beam 3 for adjusting the height of the novel soil crushing roller 1.

[0024] The new type of soil crushing roller 1 includes a soil crushing roller frame beam 11, side plates 12, end flanges 13, circular tubes 14, and intermediate flanges 15. The soil crushing roller frame beam 11 is mounted on the adjusting screw assembly 2. There are two sets of side plates 12, which are respectively mounted at both ends of the soil crushing roller frame beam 11. There are two sets of end flanges 13, which are rotatably mounted on the side plates 12 at both ends via bearings. The circular tubes 14 are welded between the two sets of end flanges 13 and are arranged in a spiral shape. Several sets of circular tubes 14 are arranged in a circular array along the circumference of the end flanges 13. Several sets of intermediate flanges 15 are evenly spaced between the two sets of end flanges 13 and are welded to the intermediate flanges 15. A roller frame reinforcing rib 111 is welded between the soil crushing roller frame beam 11 and the side plates 12. The roller frame reinforcing rib 111 is L-shaped. The end flanges 13 are provided with flange reinforcing ribs 131, which are arranged in a circular array of four sets.

[0025] The adjusting screw assembly 2 includes a soil-crushing roller connecting beam 21, an adjusting sleeve 22, a left-hand nut 23, a right-hand nut 24, a left-hand adjusting screw 25, and a right-hand adjusting screw 26. A soil-crushing roller connecting plate 31 is welded onto the rake frame connecting beam 3. The soil-crushing roller connecting beam 21 is rotatably mounted on the soil-crushing roller connecting plate 31. The soil-crushing roller frame crossbeam 11 is fixed to the soil-crushing roller connecting beam 21. The left-hand nut 23 and the right-hand nut 24 are welded to the left and right sides of the adjusting sleeve 22, respectively. The left-hand adjusting screw 25 is threaded into the left-hand nut 23 and hinged to the soil-crushing roller connecting plate 31. A connecting beam ear plate 213 is provided on the soil-crushing roller connecting beam 21. The right-hand adjusting screw 26 is threaded into the right-hand nut 24. It is hinged to the connecting beam ear plate 213; a first V-shaped clamping plate 211 is welded to the end of the soil crushing roller connecting beam 21, and a second V-shaped clamping plate 212 that matches it is connected to the first V-shaped clamping plate 211 by bolts; the soil crushing roller frame crossbeam 11 is fixed by the first V-shaped clamping plate 211 and the second V-shaped clamping plate 212; a rubber rod 214 is inserted into the installation gap between the first V-shaped clamping plate 211, the second V-shaped clamping plate 212 and the soil crushing roller frame crossbeam 11, and the rubber rod 214 is tightly fitted with the first V-shaped clamping plate 211, the second V-shaped clamping plate 212 and the soil crushing roller frame crossbeam 11; the adjusting sleeve 22 is provided with an adjusting hole 221; the connecting beam ear plate 213 is welded to the soil crushing roller connecting beam 21.

[0026] In practical use, the device is fixed to the external rake frame via the rake frame connecting beam 3. According to the soil hardness and sowing requirements, the wrench is inserted into the adjustment hole 221 of the adjustment sleeve 22 and the adjustment sleeve 22 is rotated. The adjustment sleeve 22 drives the left-hand adjustment screw 25 and the right-hand adjustment screw 26 to extend and retract synchronously, which drives the soil-crushing roller connecting beam 21 to rotate around the hinge point, thereby adjusting the height of the new soil-crushing roller. After determining the appropriate soil penetration depth, the adjustment is stopped.

[0027] External traction equipment drives the device forward, and the new type of soil crushing roller rotates under the action of soil friction. The spiral tube 14 cuts and crushes the soil clods. The intermediate disc 15 provides support for the tube 14 to prevent the tube 14 from deforming, and at the same time assists in crushing the soil clods. The reinforcing rib structure ensures that the device operates stably in high-intensity operations, and the rubber rod 214 buffers vibration and prevents the connection parts from loosening.

[0028] After the operation is completed, clean the dirt off the surface of the device; if the round tube 14 or the disc is damaged, loosen the bolts on the V-shaped clamp and remove the damaged soil-crushing roller for replacement; regularly check the wear of the threads on the adjusting screw, add lubricating oil to ensure smooth adjustment and extend the service life of the components.

[0029] In summary, this soil-crushing roller has a simple structure. The spirally distributed circular tubes 14 form continuous cutting edges, effectively buffering the impact of hard objects such as stones and extending the service life of the equipment. It boasts high efficiency and strong capacity. Through the rotation and friction of the circular tubes 14 with the soil, it can more finely break up soil clods, making it suitable for fine land preparation before crop sowing, especially effective on clay soils, reducing soil clumping and improving sowing uniformity. Operation is reliable. The smooth surface of the circular tubes 14 allows for pressure adjustment via a screw, preventing clay adhesion in moist soil. When operating on slopes, counterweight adjustment prevents machine slippage, enhancing safety. It operates stably, is easy to maintain, and has low maintenance costs. By setting the roller frame reinforcing ribs 111 in an L-shape, the welding surface is increased, thereby increasing the strength of the roller frame, making it less prone to damage and extending its service life. The connecting beam ear plate 213 and the soil-crushing roller connecting beam 21 are connected by welding, thereby strengthening the load-bearing capacity of the connecting beam ear plate 213, making the connection between the connecting beam ear plate 213 and the soil-crushing roller connecting beam 21 less prone to cracking, and extending their service life. The fixing structure of the V-shaped clamping plate and the rubber rod 214 not only ensures that the soil-crushing roller crossbeam is firmly fixed, but also effectively buffers the vibration during operation and prevents loosening and displacement.
