Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a tillage device for planting pasture in plains. Background Technology

[0002] Currently, in the field of plains forage cultivation, land tillage is a crucial step before planting. Due to the diverse soil structures and tendency for compaction in plains areas, traditional tillage equipment is mostly single-function and cannot simultaneously meet the needs of loosening the soil, leveling, and weed control. Tillage operations typically require the alternating use of multiple devices; for example, deep tillage is done with a plow, followed by leveling with a harrow, and finally, specialized equipment is used to remove residual weeds or roots, making the process quite cumbersome. Furthermore, existing tillage equipment has limitations in power output and terrain adaptability, especially when dealing with soils with high moisture content or containing many stones, which can easily lead to equipment instability or unsatisfactory results. Therefore, improving tillage efficiency while simultaneously meeting the operational needs under various soil conditions has become an urgent problem to be solved. Utility Model Content

[0019] The specific implementation method of the plain pasture planting and tilling device of this utility model is as follows: Combined with... Figures 1 to 3The tilling device includes a main frame 1, a soil loosening component 2, a leveling component 3, and a weed control component 4. All components are mechanically connected to the main frame 1 and arranged sequentially along the direction of travel of the main frame 1. The main frame 1 is the main supporting structure of the entire device, welded from rectangular steel pipes. A traction hook 19 is installed on its front crossbeam, and is fixed to the front of the main frame 1 by welding for connection to a tractor or other power equipment. The opening of the traction hook 19 is equipped with an anti-detachment buckle, which is connected to the traction hook 19 by a pin to ensure that it will not detach during traction. Retractable outriggers 17 are located on both sides of the main frame 1. The lower end of the retractable outriggers 17 is equipped with locking casters 18. The hubs of the casters 18 have elastic buffer pads made of rubber, which absorb vibrations during equipment movement and reduce pressure on the ground. The telescopic outrigger 17 is connected to the side plate of the main frame 1 through a sleeve. The outer side of the sleeve is provided with a positioning pin hole. After the positioning pin is inserted into the positioning pin hole, the height of the telescopic outrigger 17 is fixed, thereby adapting to the stable operation requirements under different terrain conditions.

[0020] The soil loosening component 2 is located at the front of the main frame 1 and mainly consists of multiple blade units 5 and an adjustment mechanism 6. The blade units 5 are connected to the lower crossbeam of the main frame 1 via hinges. The front end of each blade unit 5 has a serrated cutting edge 7, with the tips of the serrated edges facing the direction of travel of the main frame 1, to separate soil layers upon cutting into the soil. The bottom of each blade unit 5 has an arc-shaped guide plate 8, the surface of which is coated with a wear-resistant coating made of polytetrafluoroethylene (PTFE), reducing frictional resistance between the soil and the guide plate during operation. The arc-shaped guide plate 8 allows the blade units 5 to flip the soil upwards after cutting into it and guide the flipped soil to both sides via the guide plate. The adjustment mechanism 6 includes an adjusting screw 9 and a limiting block 10. One end of the adjusting screw 9 is threaded to the rear end of the blade unit 5, and the other end passes through the limiting block 10 and is secured with a nut. By rotating the adjusting screw 9, the tilt angle of the blade unit 5 can be changed, thereby adjusting the depth of the blade unit 5 cutting into the soil to adapt to the loosening needs under different soil conditions. Spacing plates are also provided between the blade units 5, and these plates are fixed to the crossbeams of the main frame 1 by bolts. The thickness of the spacing plates matches the distance between the blade units 5, and the surface of the spacing plates is covered with a lubricating coating made of graphite material, which further reduces the soil friction resistance experienced by the blade units 5 during operation.

[0021] The weed control assembly 4 is located in the middle of the main frame 1 and includes a cutting blade assembly 15 and a collection box 16. The cutting blade assembly 15 is connected to the drive system of the main frame 1 via a drive shaft. Both ends of the drive shaft are fixed to the side plates of the main frame 1 by bearings. The cutting blade assembly 15 is located below the main frame 1 and maintains a certain distance from the ground to avoid direct contact and wear. During rotation, the cutting blade assembly 15 cuts the weeds on the ground and guides the cut weed debris into the collection box 16. The collection box 16 is mounted in the middle of the main frame 1 via a slide rail. A guide plate is provided at the inlet of the collection box 16, and the guide plate is inclined and corresponds to the outlet of the cutting blade assembly 15 to ensure that the cut weed debris can smoothly enter the collection box 16. A drainage hole is provided at the bottom of the collection box 16 to drain accumulated water in humid environments and prevent the weed debris from rotting due to water accumulation.

[0022] The leveling component 3 is located at the rear of the main frame 1 and includes a roller 11 and a leveling plate 12. The roller 11 is mounted at the rear of the main frame 1 via a bearing seat. Multiple raised stripes 13 are provided on the outer circumference of the roller 11, forming grooves between them. The design of the raised stripes 13 enhances the compaction effect of the roller 11 on the soil. The leveling plate 12 is connected to the lower part of the rear of the main frame 1 via a spring connector. A flexible scraper 14 is provided on the bottom surface of the leveling plate 12. The flexible scraper 14 is made of polyurethane material, possessing a certain degree of flexibility and wear resistance. The flexible scraper 14 maintains a certain gap with the outer circumference of the roller 11. During the rotation of the roller 11, the soil is initially compacted, while the leveling plate 12, through the flexible scraper 14, pushes away excess soil and fills low-lying areas, thereby achieving soil leveling.

[0023] In practical use, the tilling device is connected to the tractor via the traction hook 19, and the tractor provides traction to move the tilling device forward. The shovel unit 5 of the loosening component 2 first cuts into the soil, peeling it apart in layers through the serrated blades 7, and guiding the turned-up soil to both sides through the arc-shaped guide plate 8. During this process, the operator can adjust the tilt angle of the shovel unit 5 according to the soil hardness and moisture using the adjustment mechanism 6 to meet different soil loosening needs. Subsequently, the cutting blade assembly 15 of the weed control component 4 cuts the weeds on the ground during rotation, and guides the cut weed debris into the collection box 16 to prevent weed residue from affecting subsequent planting operations. Finally, the roller 11 of the leveling component 3 initially compacts the soil, while the leveling plate 12 uses flexible scrapers 14 to push away excess soil and fill low-lying areas, thus achieving soil leveling. The entire tilling process integrates land tilling, leveling, and weed removal, reducing equipment replacement frequency and improving tilling efficiency. The retractable outriggers 17 and casters 18 of the main frame 1 enhance the equipment's terrain adaptability, enabling it to operate stably in soil conditions with high humidity or containing many stones.

[0024] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the operating principle and implementation steps of the tilling device is provided in conjunction with specific application scenarios.

[0025] In actual use, the tilling device is first connected to the tractor via the traction hook 19. The traction hook 19 is fixed to the front crossbeam of the main frame 1 by welding and is equipped with anti-detachment buckles to ensure the reliability of the connection. After the operator starts the tractor, the tractor's traction force moves the entire tilling device forward. At this time, the blade unit 5 of the loosening component 2 first cuts into the soil, with the tips of its serrated cutting edge 7 facing the direction of travel, which can peel off the soil in layers when cutting into the soil. Since the bottom of the blade unit 5 is equipped with an arc-shaped guide plate 8, the turned soil is guided to both sides, thereby effectively avoiding soil accumulation. The surface of the arc-shaped guide plate 8 is coated with a wear-resistant coating made of polytetrafluoroethylene, which can significantly reduce the frictional resistance between the soil and the guide plate and extend the service life of the equipment. During this process, if the soil hardness or moisture is high, the operator can adjust the tilt angle of the blade unit 5 by rotating the adjusting screw 9. One end of the adjusting screw 9 is threaded to the rear end of the blade unit 5, and the other end passes through the limiting block 10 and is fixed by a nut. By changing the position of the adjusting screw 9, the cutting depth of the blade unit 5 can be precisely controlled to adapt to the loosening needs under different soil conditions.

[0026] Subsequently, the weed removal assembly 4 begins operation. The cutting blade assembly 15 is connected to the drive system of the main frame 1 via a drive shaft, rotating at high speed under power to cut the weeds on the ground. The cutting blade assembly 15 is located below the main frame 1 and maintains a certain distance from the ground to avoid direct contact and wear. The cut weed debris is guided into the collection box 16 by a guide plate. The guide plate is designed with an angle corresponding to the outlet of the cutting blade assembly 15, ensuring that the debris can smoothly enter the collection box 16. Furthermore, the bottom of the collection box 16 is equipped with drainage holes to drain accumulated water in humid environments, preventing the weed debris from rotting due to water accumulation. This design not only improves weed removal efficiency but also avoids the impact of weed residue on subsequent planting operations.

[0027] Finally, the leveling component 3 compacts and levels the soil. The roller 11 is mounted at the rear of the main frame 1 via a bearing seat. Multiple raised stripes 13 are provided on its outer circumference, forming grooves between the stripes. During rotation, the roller 11 initially compacts the soil, increasing its density. The leveling plate 12 is connected to the lower rear of the main frame 1 via a spring connector, and its bottom surface is equipped with a flexible scraper 14. The flexible scraper 14 is made of polyurethane material, possessing a certain degree of flexibility and wear resistance, and maintains a reasonable gap with the outer circumference of the roller 11. After the roller 11 completes the initial compaction, the leveling plate 12 uses the flexible scraper 14 to push away excess soil and fill low-lying areas, thus achieving soil leveling. The spring connector design allows the leveling plate 12 to automatically adjust its position according to terrain changes, further improving the leveling effect.

[0028] During equipment operation, the retractable outriggers 17 and casters 18 on both sides of the main frame 1 play a crucial role. The retractable outriggers 17 are connected to the side plates of the main frame 1 via sleeves. Positioning pin holes are located on the outer side of the sleeves, allowing operators to insert positioning pins to fix the outrigger height according to terrain conditions, thus ensuring stable operation of the equipment under various terrain conditions. The casters 18 have elastic buffer pads made of rubber inside their hubs, which absorb vibrations during equipment movement and reduce pressure on the ground, exhibiting excellent adaptability, especially in soil conditions with high humidity or containing many stones.

[0029] Through the above steps, the tillage device achieves integrated operations of land tillage, leveling, and weed removal. The adjustment mechanism 6 of the loosening component 2 ensures that the blade unit 5 can flexibly adjust the cutting depth according to soil conditions to meet different loosening needs; the cutting blade assembly 15 and the collection box 16 of the weed treatment component 4 work together to efficiently remove and centrally process weeds; the roller 11 of the leveling component 3 works in conjunction with the leveling plate 12 to both compact the soil and ensure the flatness of the ground. The overall structure is simple in design and easy to operate, making it suitable for large-scale application in the field of plain pasture planting.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
