Description

Technical Field

[0001] This invention relates to the field of horse farm ground leveling equipment, and more specifically, to a horse farm ground leveling device. Background Technology

[0002] Equestrian arenas are one of the most basic and crucial facilities in equestrian sports and training. The quality of their surface directly affects the safety of horses and the training effect of riders. Equestrian arenas typically consist of a base layer and a surface layer. The surface layer is usually paved with a mixture of sand, gravel, and fiber materials, requiring the surface to be flat and of moderate hardness. Under the long-term trampling of horses and the effects of the natural environment, the surface layer of equestrian arenas may become uneven or even clump together, requiring the use of a grader to level it.

[0003] In existing technology, a typical grader first lifts the surface layer by pushing a rod, then scrapes the surface layer flat by scraping a scraper, and finally compacts the surface layer by pressing a cylinder. Although this device can flatten the surface layer, some clumps of the surface layer cannot be effectively broken up. These unbroken clumps pose a safety hazard to horses. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing graders are inconvenient to break up clumps on the surface, and to design a horse farm ground leveling device.

[0006] Furthermore, the drive frame includes a fixed plate installed at the lower end of the traction frame. Electric telescopic rods are installed on both sides below the fixed plate. An intercepting plate is provided below the fixed plate. A square groove is opened at the upper end of the intercepting plate. A telescopic plate is installed in the square groove. The upper sides of the telescopic plate are connected to the lower ends of the electric telescopic rods. The lower end of the telescopic plate is connected to the lower surface of the square groove through multiple telescopic springs. A take-up reel is provided on one side of the electric telescopic rod. A rotating shaft is installed on the take-up reel. A first rolling bearing is installed at one end of the rotating shaft.

Adjacent feeding rods are connected through a connecting shaft. A lifting rod is installed on the outermost feeding rod. A traction line is installed at the upper end of the lifting rod. The upper end of the traction line is connected to the take-up reel.

[0007] Furthermore, the outer diameter of the transmission gear is smaller than the outer diameter of the take-up reel.

[0008] Furthermore, the lower end of the inclined rod has clearance openings on both sides, and the connecting shaft is located at the clearance openings.

[0009] Furthermore, the movable frame includes a movable rod located below the traction frame. The movable rod has threaded holes at both ends, and a rotating screw is threadedly connected to each threaded hole. A guide groove is provided on one side of the vertical plate, and one end of the movable rod extends into the guide groove. A guide slide is provided on the other side of the movable rod, and the other end of the movable rod extends into the guide slide. The guide slide is connected to the traction frame via multiple support rods. Second rolling bearings are installed at both ends of the rotating screw. The second rolling bearings on the two rotating screws are respectively installed in the guide groove and the guide slide. A transmission sprocket is installed at one end of the rotating screw, and the two transmission sprockets are connected by a transmission chain. A servo motor is installed at the lower end of the traction frame. The rotating end of the servo motor is connected to a rotating screw via a coupling. The crushing roller is rotatably mounted on the movable rod.

[0010] Furthermore, the crushing roller has a circular hole at its axial center, the moving rod is a round rod at the middle and square rods at both ends, the round rod is located inside the circular hole, and the threaded hole is opened on the square rod.

[0011] Furthermore, baffles are installed at both ends of the round rod, and the baffles are located on both sides of the crushing roller.

[0012] Furthermore, a transverse support block is provided below the horizontal bar. The upper surface of the transverse support block is connected to the lower surface of multiple horizontal bars.

One side surface of the L-shaped limiting blocks is connected to the vertical plate, and the other side surface of the L-shaped limiting blocks is connected to the fixing block.

[0014] Furthermore, the elongated opening has limit holes on both sides, and a limit shaft is inserted through the limit holes. The limit shaft can rotate within the limit holes, and one end of the feeding rod is connected to the limit shaft.

[0015] The beneficial effects of this invention are as follows: By moving the traction frame driven by the vehicle, the clumps on the ground can be turned up first by the push rod. Then, under the action of the inclined surface of the inclined rod, the clumps can be forked up. After that, the feeding rod is rotated by the drive frame, so that the material above the inclined rod can slide onto the horizontal rod. Then, the crushing roller is driven by the moving frame to roll from above the horizontal rod, thereby crushing the clumps. The crushed material falls to the ground through the gap between the horizontal rods. This device can automatically turn up and crush the clumps on the ground, which makes it easier to level the ground and reduces safety hazards. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] This invention provides, for example Figure 1-12The device shown is a horse farm ground leveling device, including a traction frame 1. Multiple push rods 2 are installed on the front side of the lower end of the traction frame 1, and a pressure cylinder 3 is installed on the rear side of the traction frame 1. A scraper 4 is provided between the push rods 2 and the pressure cylinder 3. The scraper 4 includes a vertical plate 5 installed at the lower end of the traction frame 1. An inclined plate 6 is integrally formed at the lower end of the vertical plate 5. Multiple horizontal rods 7 are installed on the front side of the lower end of the vertical plate 5. An inclined rod 8 is integrally formed on the front side of the horizontal rods 7. Long openings 9 are opened on the horizontal rods 7 and the inclined rods 8. A feeding rod 10 is rotatably installed in the long openings 9. A drive frame 11 is installed at the lower end of the traction frame 1. The drive frame 11 can drive the feeding rod 10 to rotate. A crushing roller 12 is provided below the traction frame 1. A movable frame 13 is installed at the lower end of the traction frame 1. The movable frame 13 can drive the crushing roller 12 to roll above the horizontal rods 7.

[0020] The process of leveling the horse farm ground using this device is as follows: A traction frame 1 is installed at the rear of a vehicle, which can then move the traction frame 1. When using this device, the lower end of the push rod 2 extends into the inner side of the surface layer. The lower ends of the pressure cylinder 3 and the inclined plate 6 are placed on the surface of the surface layer, and the lower end of the inclined rod 8 is inserted into the surface layer. As the traction frame 1 moves, the push rod 2 first flips up the surface layer. Then, under the action of the inclined surface of the inclined rod 8, the clumps of the surface layer are scooped up, causing them to fall above the inclined rod 8. Fine particles can pass through... The gap between the inclined rods 8 allows the material to fall and pass through. After a period of time, the drive frame 11 drives the feeding rod 10 to deflect upward, which in turn allows the feeding rod 10 to rotate to an upward inclined state. Under the action of the inclined plane, the agglomerated surface layer slides down to the horizontal rod 7. The moving frame 13 drives the crushing roller 12 to roll above the horizontal rod 7, which crushes the agglomerated surface layer and allows the crushed surface layer to fall to the ground. Then, the inclined plate 6 can scrape the surface layer flat, and then the pressure cylinder 3 can compact the ground.

[0021] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 6 Included with instruction manual Figure 9The drive frame 11 includes a fixed plate 14 installed at the lower end of the traction frame 1. Electric telescopic rods 15 are installed on both sides below the fixed plate 14. An intercepting plate 16 is provided below the fixed plate 14. A square groove 17 is formed at the upper end of the intercepting plate 16, and a telescopic plate 18 is installed within the square groove 17. The upper sides of the telescopic plate 18 are connected to the lower ends of the electric telescopic rods 15. The lower end of the telescopic plate 18 is connected to the lower surface of the square groove 17 via multiple telescopic springs 19. A take-up reel 20 is provided on one side of the electric telescopic rod 15, and a rotating shaft is installed on the take-up reel 20. 21. A first rolling bearing 22 is installed at one end of the rotating shaft 21. The first rolling bearing 22 is connected to the lower end of the fixed plate 14 through the fixed rod 23. A transmission gear 24 is installed on the rotating shaft 21. A lifting rack 25 is provided on one side of the transmission gear 24. The lifting rack 25 is connected to the telescopic plate 18 through the connecting rod 26. The adjacent feeding rods 10 are connected through the connecting shaft 27. A lifting rod 28 is installed on the outermost feeding rod 10. A traction line 29 is installed at the upper end of the lifting rod 28. The upper end of the traction line 29 is connected to the take-up reel 20.

[0022] The process of the drive frame 11 driving the feeding rod 10 to rotate is as follows: Under normal conditions, the feeding rod 10 is located inside the elongated opening 9, the electric telescopic rod 15 is in its shortest retracted state, and the intercepting plate 16 is located above the tilting rod 8 but not in contact with it. It is controlled by an external controller. Every time it is necessary to feed the agglomerated surface layer, the electric telescopic rod 15 is activated to extend, which can push the telescopic plate 18 and the intercepting plate 16 downward. When the lower end of the intercepting plate 16 contacts the tilting rod 8, the lifting rack 25 moves to the transmission gear. The wheel 24 is moved to one side, causing the electric telescopic rod 15 to continue extending. At this point, the interceptor plate 16 is blocked by the tilting rod 8 and will not continue to move, but the telescopic plate 18 will continue to move downward and compress the telescopic spring 19. The telescopic plate 18 can drive the lifting rack 25 to continue moving downward through the connecting rod 26, thereby allowing the lifting rack 25 to mesh with the transmission gear 24. As the lifting rack 25 continues to move downward, it drives the transmission gear 24, the rotating shaft 21, and the take-up reel 20 to rotate. The take-up reel 20 can take in the traction line 29. The feeding rods 10 are then rotated upwards via the traction line 29, lifting rod 28, and connecting shaft 27. This allows the agglomerated surface layer to slide above the horizontal rod 7. When the feeding rods 10 rotate upwards, the intercepting plate 16 intercepts the rear surface layer, preventing the agglomerated surface layer from moving above the inclined rod 8. After the feeding rods 10 have finished feeding, the electric telescopic rod 15 is retracted, which in turn moves the telescopic plate 18 upwards. The intercepting plate 16 will not move under the elastic force of the telescopic spring 19. This allows the surface layer to continue to be blocked. When the telescopic plate 18 moves upward, it can drive the lifting rack 25 to move upward. Then, through the meshing of the gears, the transmission gear 24, the rotating shaft 21, and the take-up reel 20 can rotate in the opposite direction, releasing the traction line 29. Then, under the action of gravity, the feeding rod 10 can return to its original position. Afterward, through the telescopic plate 18 and the telescopic spring 19, the intercepting plate 16 can be driven to move upward, and the intercepting plate 16 can be separated from the tilting rod 8, which makes it easier for the agglomerated surface layer to move above the tilting rod 8.

[0023] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The outer diameter of the transmission gear 24 is smaller than that of the take-up reel 20. When the telescopic plate 18 moves a small distance, the transmission gear 24 can rotate a small angle through gear transmission. However, the angular velocities of the transmission gear 24 and the take-up reel 20 are the same, which allows the take-up reel 20 to wind up more traction line 29 when it rotates the same angle as the transmission gear 24.

[0024] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 6 Included with instruction manual Figure 9The tilting rod 8 has clearance openings 30 on both sides at its lower end. The connecting shaft 27 is located at the clearance opening 30, which allows the connecting shaft 27 to be located at the lower end of the upper surface of the tilting rod 8, preventing the surface layer from being intercepted.

[0025] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 3 Instruction manual attached Figure 4 Instruction manual attached Figure 6 Instruction manual attached Figure 7 Included with instruction manual Figure 8 The movable frame 13 includes a movable rod 31 located below the traction frame 1. The movable rod 31 has threaded holes 32 at both ends, and a rotating screw 33 is threadedly connected to the threaded holes 32. A guide groove 34 is opened on one side of the vertical plate 5. One end of the movable rod 31 extends into the guide groove 34, and a guide slide 35 is provided on the other side of the movable rod 31. The other end of the movable rod 31 extends into the guide slide 35. The guide slide 35 is connected to the traction frame 1 through multiple support rods 36. Second rolling bearings 37 are installed at both ends of the rotating screw 33. The second rolling bearings 37 on the two rotating screws 33 are respectively installed in the guide groove 34 and the guide slide 35. A transmission sprocket 38 is installed at one end of the rotating screw 33. The two transmission sprockets 38 are connected by a transmission chain 39. A servo motor 40 is installed at the lower end of the traction frame 1. The rotating end of the servo motor 40 is connected to a rotating screw 33 through a coupling. The crushing roller 12 is rotatably mounted on the movable rod 31.

[0026] The process of the moving frame 13 driving the crushing roller 12 to roll is as follows: The servo motor 40 is started to rotate, which can drive a rotating screw 33 and the transmission sprocket 38 above it to rotate. The transmission sprockets 38 on the two rotating screws 33 are connected by a transmission chain 39, which can make the two rotating screws 33 rotate. By installing a tensioning device between the two transmission sprockets 38, the two rotating screws 33 can rotate synchronously. The rotating screw 33 and the threaded hole 32 are connected by threads, which can make the moving rod 31 move. The guide groove 34 and the guide slide 35 can guide and support the moving rod 31. When the moving rod 31 moves, it can drive the crushing roller 12 to roll.

[0027] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 3 Instruction manual attached Figure 4 Instruction manual attached Figure 6 Instruction manual attached Figure 7 Instruction manual attached Figure 8 Included with instruction manual Figure 12The crushing roller 12 has a circular hole 41 at its axial center. The moving rod 31 has a circular rod 42 in the middle and square rods 43 at both ends. The circular rod 42 is located inside the circular hole 41, and the threaded hole 32 is opened on the square rod 43. When the moving rod 31 moves, the circular rod 42 can contact the inside of the circular hole 41 and push the crushing roller 12 to move. Since there is friction between the crushing roller 12 and the horizontal rod 7, the crushing roller 12 can roll above the horizontal rod 7. When rolling, the surface layer of the agglomerate can be crushed by the gravity of the crushing roller 12. There is also a gap between the circular rod 42 and the circular hole 41, which makes it easy for the crushing roller 12 to swing up and down.

[0028] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 3 Instruction manual attached Figure 4 Instruction manual attached Figure 6 Instruction manual attached Figure 7 Included with instruction manual Figure 8 The round rod 42 is equipped with baffles 44 at both ends. The baffles 44 are located on both sides of the crushing roller 12. The baffles 44 can limit the movement of the crushing roller 12 on both sides to prevent the crushing roller 12 from swaying left and right.

[0029] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 5 Instruction manual attached Figure 6 Included with instruction manual Figure 7 A transverse support block 45 is provided below the horizontal bar 7. The upper surface of the transverse support block 45 is connected to the lower surface of multiple horizontal bars 7, which can enhance the strength of the horizontal bar 7. The two sides of the transverse support block 45 are connected to the fixing plate 14 through fixing blocks 46. The fixing blocks 46 have round openings 47 to avoid the rotating screw 33.

[0030] Refer to the instruction manual appendix Figure 6 Instruction manual attached Figure 7 Instruction manual attached Figure 8 Included with instruction manual Figure 12 The vertical plate 5 is equipped with L-shaped limiting blocks 48 at both ends. The corners of the L-shaped limiting blocks 48 are rounded and chamfered. Multiple feeding ports 49 are opened on the L-shaped limiting blocks 48. One side surface of the L-shaped limiting blocks 48 is connected to the vertical plate 5, and the other side surface of the L-shaped limiting blocks 48 is connected to the fixing block 46. When the crushing rollers 12 move to both sides, if the agglomerated surface layer is not crushed, but instead pushed to both sides, the surface layer can be moved into the L-shaped limiting blocks 48 and then crushed by the L-shaped limiting blocks 48 and the crushing rollers 12.

[0031] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 5 Instruction manual attached Figure 6 Included with instruction manual Figure 10The long opening 9 has limit holes 50 on both sides, and a limit shaft 51 is provided through the limit hole 50. The limit shaft 51 can rotate within the limit hole 50. One end of the feeding rod 10 is connected to the limit shaft 51. The limit hole 50 can limit the limit shaft 51, thereby facilitating the rotation of the feeding rod 10 around the limit shaft 51.
