Description

Technical Field

[0001] This invention relates to the field of land leveling, specifically to an efficient land leveling device for land development and utilization. Background Technology

[0002] During land development, it is necessary to plan the land into a high-quality flat area, which requires leveling the land surface. However, the presence of stones or non-fragile materials on the land surface during the leveling process can affect the leveling operation.

[0003] When leveling surfaces containing pebbles and large stones, it is impossible to remove the pebbles and stones from the soil, which can easily affect the levelness of the surface. Furthermore, if there are potholes on the surface during the leveling process, they cannot be filled immediately after the leveling device has moved, requiring rework or manual filling, resulting in low filling efficiency.

[0013] Beneficial effects: (1) The soil scraping mechanism installed on the frame can scrape the soil into the inside of the bulldozer bucket. During the forward movement of the frame, the excess soil is pushed through the bulldozer bucket to level the land. The kinetic energy of the wheels is transmitted to the transmission mechanism. The transmission mechanism rotates to drive the collection mechanism to rotate. The collection mechanism rotates to collect stones and rocks in the soil. When the scraping mechanism moves upward to the rear of the frame, the collection mechanism moves downward and contacts the ground, which can collect stones on the ground. When the scraping mechanism moves downward, the collection mechanism moves upward synchronously. When the scraping mechanism is performing the soil leveling work, the collection mechanism is located behind the frame and is separated from the ground at this time.

[0014] (2) The second driving member pushes the moving rod downward. The moving rod moves and drives the sliding plate connected to it to move downward. When the sliding plate moves downward, it drives the multiple second guide rods on it to move. When the second guide rods move, they move along the second guide groove, so that the moving trajectory of the sliding plate is the same as the trajectory of the second guide groove. This causes the scraper to slide downward on the frame and then slide in an arc to the bottom of the frame. When the scraper just slides to the bottom of the frame, the locking mechanism locks the scraper to the frame, which facilitates the stability of the scraper when it comes into contact with the soil during the process of leveling the ground.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] In one embodiment, please refer to the appendix to the specification. Figure 1-12As shown, the present invention discloses an efficient land leveling device for land development and utilization, comprising a frame 1, on which a bulldozer bucket is mounted; a connecting frame 11 is mounted on the frame 1; a support beam 16 is mounted on the frame 1; wheels 14 are mounted on the support beam 16; a tailing mechanism 2 is mounted on the frame 1 for collecting stones; a transmission mechanism 3 is mounted on the frame 1, connected to the wheels 14, the rotation of the wheels 14 driving the transmission mechanism 3 to rotate; a scraping mechanism 5 is mounted on the frame 1, a collecting mechanism 4 is connected to the transmission mechanism 3; when the scraping mechanism 5 moves downward, it drives the collecting mechanism 4 to move upward; when the scraping mechanism 5 moves downward, it drives the collecting mechanism 4 to move upward. A first driving member 13 connected to the support beam 16 is mounted on the frame 1, the first driving member 13 for adjusting the height of the support beam 16; a hydraulic tank 12 is mounted on the frame 1, the hydraulic tank 12 providing stable hydraulic support for the first driving member 13.

[0020] The connecting frame 11 is connected to the tractor, which drives the connecting frame 11 to move, thereby driving the chassis 1 to move. The tractor can be a tractor. The soil scraping mechanism 5 set on the chassis 1 can scrape the soil into the inside of the bulldozer bucket. When the chassis 1 moves forward, the excess soil is pushed by the bulldozer bucket, thereby leveling the land. The kinetic energy of the wheels 14 when they move forward is transmitted to the transmission mechanism 3. The transmission mechanism 3 rotates and drives the collection mechanism 4 to rotate. The collection mechanism 4 rotates and collects stones and rocks in the soil. When the soil scraping mechanism 5 moves upward to the rear of the chassis 1, the collection mechanism 4 moves downward and contacts the ground, which can collect stones on the ground. When the soil scraping mechanism 5 moves downward, the collection mechanism 4 moves upward simultaneously. When the soil scraping mechanism 5 is performing soil leveling work, the collection mechanism 4 is located behind the chassis 1 and is separated from the ground at this time.

[0021] In one embodiment, please refer to the appendix to the specification. Figure 1-6 As shown, the scraping mechanism 5 includes a scraper 53 slidably mounted on a frame 1. A support plate 54 located on the outer side of the frame 1 is provided on the support plate 54. A second guide groove 57 is provided on the support plate 54. A sliding plate 55 is slidably mounted on the support plate 54. A second guide rod 56 is provided on the sliding plate 55 and slides inside the second guide groove 57. The sliding plate 55 is located on the scraper 53 and is used to push the scraper 53 to move on the frame 1. A support rod 52 is connected to the sliding plate 55 and is connected to a moving rod 51. A second driving member 50 is provided on the frame 1 and is connected to the moving rod 51 to drive the moving rod 51 to move up and down.

[0022] When the scraper 53 needs to be moved to the bottom of the frame 1, it works with the bulldozer bucket to scrape and level the soil. The second drive member 50 pushes the moving rod 51 downward. When the second drive member 50 pushes the moving rod 51, the second drive member 51 can slide relative to the moving rod 50 without separating; thus ensuring that the scraper 53 always moves along the second guide groove 57. The movement of the moving rod 51 drives the sliding plate 55 connected to it to move downward. When the sliding plate 55 moves downward, it drives the multiple second guide rods 56 on it to move. When the second guide rods 56 move, they move along the second guide groove 57, so that the movement trajectory of the sliding plate 55 is the same as the trajectory of the second guide groove 57. This causes the scraper 53 to slide downward on the frame 1 and then slide in an arc to the bottom of the frame 1. When the scraper 53 just slides to the bottom of the frame 1, the locking mechanism 6 locks the scraper 53 to the frame 1, which facilitates the stability of the scraper 53 when it comes into contact with the soil during the leveling process.

[0023] In one embodiment, please refer to the appendix to the specification. Figure 4-6 As shown, the frame 1 is equipped with a locking mechanism 6 for locking the scraping mechanism 5. The locking mechanism 6 is used to lock the scraper 53 onto the frame 1. The locking mechanism 6 includes multiple locking grooves 65 on the scraper 53. A locking rod 61 is provided inside the locking groove 65 and engages with it. The locking rod 61 is slidably mounted on the frame 1. A protrusion 64 is provided inside the locking groove 65. A pressing groove 66 is provided on the locking rod 61. The protrusion 64 is used to push the pressing groove 66 to move. A moving block 67 is provided on the locking rod 61 to guide the movement of the locking rod 61. The moving block 67 has a square cross-section. A third elastic element 62 is provided on the moving rod 51. The third elastic element 62 is used to push the locking rod 61 into the interior of the locking groove 65. A stop block 63 is provided on the locking rod 61. A third elastic element 62 is provided on one side of the stop block 63. The stop block 63 is used to block the movement of the third elastic element 62.

[0024] During the movement of the scraper 53, the side of the scraper 53 first contacts the end of the locking rod 61. Since both the side of the scraper 53 and the end of the locking rod 61 are arc-shaped, the scraper 53 presses against the locking rod 61, causing the locking rod 61 to move to the end face of the scraper 53. As the scraper 53 continues to move, until the second guide rod 56 reaches the bottom of the second guide groove 57, the locking rod 61 just enters the interior of the locking groove 65. Since the locking rod 61 and the locking groove 65 correspond one-to-one, and multiple sets of locking rods 61 and locking grooves 65 are provided, the locking rod 61 can lock the scraper 53 onto the frame 1. When the scraper 53 is working, the cross-section of the moving block 67... The square structure allows the movable block 67 to move along the locking groove 65 within the frame 1. Therefore, the locking rod 61 will not rotate as it moves with the movable block 67. Due to the horizontal thrust on the scraper 53, the locking rod 61 will not disengage from the interior of the locking groove 65. As the scraper 53 moves upward and is retracted to the rear of the frame 1, the protrusion 64 abuts against the pressing groove 66. Since the pressing groove 66 is inclined, the scraper 53 pushes the pressing groove 66 and the protrusion 64 apart as it moves upward at an incline, until the end of the locking rod 61 is pressed to the outside of the locking groove 65, causing the locking rod 61 to slide on the end face of the scraper 53 until it separates from the scraper 53.

[0025] In one embodiment, please refer to the appendix to the specification. Figure 1-3 As shown in Figures 8-9 and 11-12, the transmission mechanism 3 includes a rotating block 33 mounted on the frame 1, a connecting pin 36 mounted on the rotating block 33, and the rotating block 33 rotating around the connecting pin 36; a first guide groove 331 mounted on the rotating block 33; a rotating sleeve 15 mounted on the support beam 16, a transmission rod 31 mounted inside the rotating sleeve 15, a connecting sleeve 32 mounted on the transmission rod 31, and a first guide rod 321 mounted on the connecting sleeve 32, the first guide rod 321 moving with the first guide groove 331; the rotating block 33 is connected to the second driving member 50.

[0026] The transmission mechanism 3 further includes a transmission assembly for driving the collection mechanism 4 to rotate. The transmission assembly includes a drive rod 311 connected to the wheel 14. The drive rod 311 is slidably connected to the transmission rod 31. The transmission rod 31 has an inner groove 38 inside. The end of the drive rod 311 has an inner rod 39. The inner rod 39 slides inside the inner groove 38. The end of the transmission rod 31 has a first helical gear 37.

[0027] When the second drive member 50 moves upward, pulling the scraper 53 upward and retracting it to the rear of the frame 1, the second drive member 50 pulls the rotating block 33 to rotate. The rotating block 33 rotates, causing the first guide groove 331 to rotate. Consequently, the first guide groove 331 presses the first guide rod 321 downward, causing the first guide rod 321 to move downward, and vice versa. When the first guide rod 321 moves downward, the connecting sleeve 32 moves downward, which in turn drives the collecting mechanism 4 to move downward. The rotating sleeve 15 has two transmission gears inside. One gear is fixed to the connecting shaft on the wheel 14 via the drive rod 311. (See the attached instruction manual) Figure 12 Another gear is fixed to the inner rod 39 via the drive rod 311. When the wheel 14 rotates, it drives the inner rod to rotate. When the wheel 14 rotates, it drives the transmission rod 31 to rotate. The transmission rod 31 drives the first helical gear 37 to rotate synchronously. When the connecting sleeve 32 moves up or down, the inner rod 39 will slide inside the inner groove 38. Since the cross-section of the inner rod 39 and the inner groove 38 is square, the inner rod 39 can still maintain the transmission mode after sliding inside the inner groove 38, so that the rotation of the inner rod 39 drives the transmission rod 31 to rotate.

[0028] In one embodiment, please refer to the appendix to the specification. Figure 1-3 As shown in Figure 8, the collecting mechanism 4 includes a support cylinder 41 connected to a transmission rod 31. Inside the support cylinder 41 is a second helical gear meshing with a first helical gear 37. A rotating rod 42 is mounted on the second helical gear. A sliding groove 46 is mounted on the rotating rod 42. A sliding rod 45 is mounted inside the sliding groove 46. The sliding rod 45 slides within the sliding groove 46. Multiple scraping rods 43 are mounted on the sliding rod 45, and a screen 44 is positioned between the scraping rods 43. The screen 44 moves synchronously with the sliding rod 45. Inside the support cylinder 41 is a driven groove 48. A driven rod 47 is connected to the end of the sliding rod 45. The driven rod 47 moves within the driven groove 48, driving the sliding rod 45 to reciprocate horizontally.

[0029] The driven groove 48 inside the support cylinder 41 causes the driven rod 47 to move along the height difference of the driven groove 48 when it passes through the inside of the driven groove 48. This causes the driven rod 47 to drive the sliding rod 45 to move synchronously. During the movement of the sliding rod 45, it can drive the screen 44 set on it to move back and forth along the direction of the sliding rod 45. When the rotating rod 42 rotates, the rotating rod 42 drives the scraping rod 43 to rotate. The sliding rod 45 set on the rotating rod 42 also rotates synchronously. That is, the sliding rod 45 moves back and forth synchronously when it rotates. This causes the scraping rod 43 to screen the excavated stones, rocks and soil through the screen 44. After screening, the screen 44 leaves the stones and rocks behind. As the screen 44 continues to rotate, the stones and rocks are fed into the tailing mechanism 2.

[0030] In one embodiment, please refer to the appendix to the specification. Figure 1 and 10 As shown, the tailing mechanism 2 includes a tailing box 21 connected to the frame 1. A partition plate 22 is provided on the tailing box 21. A rotating shaft 23 is provided on the partition plate 22. A vibrating plate 24 is connected to the rotating shaft 23. A first sliding groove 28 is provided on the tailing box 21. The first sliding groove 28 is used to guide the movement of the vibrating plate 24. A plurality of first elastic elements 25 are provided below the vibrating plate 24. The first elastic elements 25 are used to push the vibrating plate 24 to vibrate up and down. An insert plate 29 is provided on the tailing box 21.

[0031] The tailing mechanism 2 further includes a leveling component for leveling the soil. The leveling component includes a second slidable groove 211 on the tailing box 21. A movable shaft 210 is slidably arranged inside the second slidable groove 211. A scraper 27 is rotatably arranged on the movable shaft 210. A second elastic element 26 is arranged on one side of the scraper 27. The second elastic element 26 is arranged at the bottom of the tailing box 21 and is used to push the scraper 27 to rotate to a position where it is in contact with the ground.

[0032] When the stones and rocks are put into the tailing box 21, the tailing box 21 moves with the frame 1, causing the vibrating plate 24 inside the tailing box 21 to vibrate and push the stones and rocks backward to one side of the insert plate 29. During the movement of the tailing box 21, the scraper 27 at the bottom of the tailing box 21 will scrape the soil and make the ground more flat. When the wheel 14 moves in the opposite direction, in order to prevent the scraper 27 from getting stuck on the ground, the moving shaft 210 is stored inside the second sliding groove 211. When the scraper 27 moves in the opposite direction with the wheel 14, the scraper 27 is squeezed by the ground and stored inside the second sliding groove 211, so that the bottom of the scraper 27 is just separated from the ground and the scraper 27 will not get stuck.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
