DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-11 This application is described in further detail.

[0019] The present application embodiment discloses a farmland surface leveling device. Figure 1 As shown, a farmland surface leveling device includes a base 1, a push handle 11 is installed on the upper surface of the base 1, and rollers 12 are installed at the four corners of the lower surface of the base 1. The user can push the leveling device to walk in the farmland through the push handle 11.

[0020] A loosening unit 2, a collecting unit 3, a flattening unit 4 and a linkage unit 5 are provided on the base 1. The loosening unit 2 includes a first rotating shaft 21 and a driving member. The axes of the first rotating shaft 21 and the roller 12 are parallel to each other, and the first rotating shaft 21 rotates around its own axis and is connected to the base 1; the driving member is a motor 22 installed on the base 1, and the output shaft of the motor 22 is connected to the first rotating shaft 21 through a belt drive, so that the motor 22 can drive the first rotating shaft 21 to rotate.

[0021] like Figure 1 and Figure 2As shown, a plurality of rows of soil-breaking spikes 23 are installed on the side wall of the first rotating shaft 21, and each row of soil-breaking spikes 23 are arranged in sequence along the axial direction of the first rotating shaft 21. During the rotation of the first rotating shaft 21, the first rotating shaft 21 will drive the soil-breaking spikes 23 to rotate and loosen the soil.

[0022] In this embodiment, there are three rows of soil-breaking spikes 23, and each row of soil-breaking spikes 23 is staggered with respect to the soil-breaking spikes 23 in the adjacent row, so as to improve the soil loosening effect of the soil-breaking spikes 23.

[0023] like Figures 2 to 4 As shown, a sleeve 24 is slidably sleeved on the soil-breaking thorn 23, and each row of sleeves 24 is commonly connected to the same connecting rod 25; two guide rails 13 are installed on the base 1, and the two ends of the connecting rod 25 are respectively slidably matched with the two guide rails 13, and the guide rail 13 is arranged in a ring shape and is divided into a contraction section 131, an extension section 133 and two transition sections 132, one end of the extension section 133 is connected to one end of the contraction section 131 through one of the transition sections 132, and the other end of the extension section 133 is connected to the other end of the contraction section 131 through the other transition section 132.

[0024] During the process of soil-breaking thorn 23 loosening the soil, soil-breaking thorn 23 will drive connecting rod 25 to slide on guide rail 13 through sleeve 24, and connecting rod 25 will be in contraction section 131 at this time; after soil-breaking thorn 23 rotates upward and disengages from the soil, connecting rod 25 will move from contraction section 131 to extension section 133, and sleeve 24 will move from one end of soil-breaking thorn 23 toward first rotating shaft 21 to one end of soil-breaking thorn 23 away from first rotating shaft 21, so that soil adhered to soil-breaking thorn 23 is pushed off by sleeve 24, so that soil-breaking thorn 23 can loosen soil in subsequent process; afterwards, connecting rod 25 will move from extension section 133 to contraction section 131, and sleeve 24 will move from one end of soil-breaking thorn 23 away from first rotating shaft 21 to one end of soil-breaking thorn 23 toward first rotating shaft 21, so that sleeve 24 moves to reset, and soil-breaking thorn 23 will continue to loosen soil at this time.

[0025] like Figure 5 As shown, the collecting unit 3 includes a first collecting box 31 and a second collecting box 32 installed on the base 1. The first collecting box 31 and the second collecting box 32 are both spaced apart from the ground. The first collecting box 31 is located in front of the loosening unit 2, and the second collecting box 32 is located behind the loosening unit 2. In the process of loosening the soil, the stones that are pushed forward by the soil-breaking spikes 23 will fall into the first collecting box 31, and the soil that is pushed by the sleeve 24 and separated from the soil-breaking spikes 23 will fall into the second collecting box 32. This part of the soil may be mixed with some stones, thereby realizing the separation and collection of the stones in the soil, preventing the stones from affecting the leveling of the soil and the normal growth of crops.

[0026] like Figure 6 and Figure 8 As shown, the interior of the first collecting box 31 is divided into a collecting cavity 311 and a guiding cavity 312. The guiding cavity 312 is inclined, and the lower end of the guiding cavity 312 is spaced apart from the ground. The higher end of the guiding cavity 312 is connected to the collecting cavity 311, so that the stones pushed forward by the soil-breaking spikes 23 can enter the collecting cavity 311 through the guidance of the guiding cavity 312, thereby improving the collection effect of the stones. In addition, the lowest point of the collecting cavity 311 is lower than the higher end of the guiding cavity 312, so that the stones that fall into the collecting cavity 311 are not easy to fall out.

[0027] A plurality of first soil dropping troughs 313 are provided at the bottom of the first aggregate box 31. Soil may adhere to the stones entering the first aggregate box 31. When the stones collide with the first aggregate box 31, they will vibrate. At this time, part of the soil on the stones will detach from the stones and fall back to the ground through the first soil dropping troughs 313, thereby avoiding unnecessary weight increase of the leveling equipment as much as possible and allowing more stones to be collected in the first aggregate box 31.

[0028] like Figure 7 As shown, a plurality of second soil troughs 321 are provided at the bottom of the second aggregate box 32. The soil entering the second aggregate box 32 will be mixed with stones. When the soil collides with the second aggregate box 32, it will vibrate. At this time, the soil will separate from the stones and fall back to the ground through the second soil troughs 321, thereby avoiding unnecessary weight increase of the leveling equipment as much as possible and allowing more stones to be collected in the second aggregate box 32.

[0029] like Figure 6 and Figure 7 As shown, the height of the area of ​​the first aggregate box 31 located between two adjacent first soil dropping grooves 313 gradually decreases from its center toward the first soil dropping groove 313, and the height of the area of ​​the second aggregate box 32 located between two adjacent second soil dropping grooves 321 gradually decreases from its center toward the second soil dropping groove 321. The soil can slide downward along the area of ​​the first aggregate box 31 located between the two adjacent first soil dropping grooves 313 and the area of ​​the second aggregate box 32 located between the two adjacent second soil dropping grooves 321, so that the soil is not easily accumulated in the first aggregate box 31 and the second aggregate box 32.

[0030] like Figures 6 to 8 As shown, a second rotating shaft 33 is provided on the base 1, and the axes of the second rotating shaft 33 and the first rotating shaft 21 are parallel to each other. The second rotating shaft 33 is rotatably connected to the base 1 around its own axis, and two first rotating plates 331, a first torsion spring 332 and a plurality of first shifting rods 333 are installed on the second rotating shaft 33, and the two ends of the first torsion spring 332 are respectively connected to the second rotating shaft 33 and the base 1, and the first shifting rod 333 corresponds to the first soil dropping groove 313 one by one and is rotatably penetrated in the first soil dropping groove 313.

[0031] The first lever 333 is a lever for sliding the first rotary plate 331 to the first bottom trough 313 so that the soil attached to the rock is separated from the rock, thereby improving the effect of separating the soil from the rock. Then, the first rotary plate 331 is rotated and separated from the push plate 251. At this time, the first torsion spring 332 is restored to its natural state, so that the first lever 333 and the first rotary plate 331 are rotated and reset. During the rotation process, the first lever 333 moves the rock and soil in the first rotary plate 31 so that the soil falls back to the ground through the first bottom trough 313.

[0032] A third rotating shaft 34 is provided on the base 1. The axes of the third rotating shaft 34 and the first rotating shaft 21 are parallel to each other. The third rotating shaft 34 is rotatably connected to the base 1 around its own axis. Two second rotating plates 341, a second torsion spring 342 and a plurality of second levers 343 are installed on the third rotating shaft 34. The two ends of the second torsion spring 342 are respectively connected to the third rotating shaft 34 and the base 1. The second lever 343 corresponds to the second soil dropping groove 321 one by one and is rotatably penetrated in the second soil dropping groove 321.

[0033] When the connecting rod 25 moves from the extension section 133 to the contraction section 131, the connecting rod 25 will push the second rotating plate 341 to rotate rapidly through the pushing plate 251, and the second rotating plate 341 will drive the second lever 343 to rotate rapidly in the second soil dropping groove 321 through the third rotating shaft 34, and the second lever 343 will quickly hit the soil in the second collecting box 32, so that the soil is broken up, thereby improving the separation effect of soil and stones; then the second rotating plate 341 will rotate and disengage from the pushing plate 251, and the second torsion spring 342 will return to its natural state, so that the second lever 343 and the second rotating plate 341 will rotate and reset, and the second lever 343 will move the stones and soil in the second collecting box 32 during the rotation process, so that the soil falls back to the ground through the second soil dropping groove 321.

[0034] like Fig. 9 and Fig.10 As shown, the flattening unit 4 includes a lifting seat 41 and a pressure roller 43. A pressure plate 42 is installed on the lifting seat 41, and the pressure plate 42 is located behind the second collecting box 32; the linkage unit 5 can be a cylinder, and the piston rod of the cylinder can drive the lifting seat 41 to rise and fall, so that the pressure plate 42 flattens the loosened ground.

[0035] like Figures 9 to 11As shown, in this embodiment, the linkage unit 5 includes two vertically arranged elastic telescopic rods 51, and the two ends of the elastic telescopic rods 51 are respectively connected to the base 1 and the lifting seat 41; a vertically arranged first rack 52 is installed on the lifting seat 41, and a first gear 53 is meshed on the first rack 52, and the first gear 53 is fixedly sleeved on the third rotating shaft 34.

[0036] When the push plate 251 pushes the second rotating plate 341 to rotate rapidly, the second rotating plate 341 will drive the first gear 53 to rotate rapidly through the third rotating shaft 34, the first gear 53 will cause the first rack 52 to drop rapidly, and the first rack 52 will drive the pressing plate 42 to hit the ground rapidly through the lifting seat 41, so as to improve the leveling effect of the loosened ground.

[0037] When the second rotating plate 341 rotates and disengages from the pushing plate 251, the second torsion spring 342 will return to its natural state, causing the second lever 343 and the second rotating plate 341 to rotate and return to their original state, and the elastic telescopic rod 51 will also return to its natural state, causing the lifting seat 41 and the pressing plate 42 to rise and return to their original state. At this time, the pressing plate 42 will be spaced apart from the ground, thereby reserving space for the pressing plate 42 to descend.

[0038] The pressure roller 43 is located behind the pressure plate 42. The pressure roller 43 is parallel to the axis of the first rotating shaft 21. The pressure roller 43 rotates around its own axis and is connected to the base 1 and rolls against the ground. That is, during the movement of the leveling equipment, the pressure roller 43 will roll the ground leveled by the pressure plate 42, thereby further leveling the ground.

[0039] like Fig.10 As shown, a brush roller 14 is provided on the base 1, and the axes of the brush roller 14 and the pressure roller 43 are parallel to each other. The brush roller 14 rotates around its own axis and is connected to the base 1 and contacts the pressure roller 43. In the process of the pressure roller 43 rotating to flatten the ground, the brush roller 14 will brush off the soil attached to the surface of the pressure roller 43 to ensure the leveling effect of the pressure roller 43 on the ground.

[0040] It is worth noting that the brush roller 14 is located between the pressure roller 43 and the pressure plate 42, so that the soil brushed off by the brush roller 14 can fall back to the front of the pressure roller 43, so that the pressure roller 43 can roll this part of the soil to improve the leveling effect of the ground.

[0041] A fourth rotating shaft 54 ​​is provided on the base 1. The fourth rotating shaft 54 ​​is parallel to the axis of the brush roller 14. The fourth rotating shaft 54 ​​is connected to the base 1 by rotating around its own axis. The fourth rotating shaft 54 ​​is connected to the brush roller 14 through a belt drive. A second gear 55 is fixedly sleeved on the fourth rotating shaft 54. A second rack 56 is meshed on the second gear 55. The second rack 56 is vertically arranged and installed on the lifting seat 41.

[0042] During the lifting process of the lifting seat 41, the lifting seat 41 will drive the second gear 55 to rotate through the second rack 56, and the second gear 55 will drive the brush roller 14 to rotate back and forth on the surface of the pressure roller 43 through the fourth rotating shaft 54 ​​to improve the cleaning effect of the brush roller 14 on the surface of the pressure roller 43.

[0043] The implementation principle of a farmland surface leveling device in the embodiment of the present application is as follows: during the leveling process of the farmland, the user will push the leveling device to walk in the farmland through the push handle 11, the motor 22 will drive the first rotating shaft 21 to rotate through the belt transmission, and the first rotating shaft 21 will drive the soil-breaking spikes 23 to rotate and loosen the soil; the soil-breaking spikes 23 will push the stones in the soil forward to the first collecting box 31 for collection, and the soil-breaking spikes 23 will drive the connecting rod 25 to slide on the guide rail 13 through the sleeve 24, and the connecting rod 25 will push the first The rotating plate 331 rotates rapidly, and the first rotating plate 331 will drive the first lever 333 to rotate rapidly in the first soil dropping trough 313 through the second rotating shaft 33, and the first lever 333 will quickly hit the stones in the first collecting box 31, so that the soil attached to the stones will be separated from the stones; then the first torsion spring 332 will prompt the first lever 333 and the first rotating plate 331 to rotate and reset, and the first lever 333 will move the stones and soil in the first collecting box 31 so that the soil will fall back to the ground through the first soil dropping trough 313.

[0044] Then the sleeve 24 will move from one end of the soil-breaking thorn 23 toward the first rotating shaft 21 to the end of the soil-breaking thorn 23 away from the first rotating shaft 21, so that the soil adhered to the soil-breaking thorn 23 is pushed by the sleeve 24 to fall into the second collecting box 32; thereafter, the sleeve 24 will move to reset, and the connecting rod 25 will push the second rotating plate 341 to rotate rapidly through the pushing plate 251, and the second rotating plate 341 will drive the second lever 343 to rotate rapidly in the second soil dropping groove 321 through the third rotating shaft 34, and the second lever 343 will quickly hit the soil in the second collecting box 32, so that the soil is scattered; then the second torsion spring 342 will prompt the second lever 343 and the second rotating plate 341 to rotate and reset, and the second lever 343 will move the stones and soil in the second collecting box 32 during the rotation process, so that the soil falls back to the ground through the second soil dropping groove 321.

[0045] During the rotation process, the second rotating plate 341 will drive the first gear 53 to rotate rapidly through the third rotating shaft 34, and the first gear 53 will prompt the first rack 52 to descend rapidly. The first rack 52 will drive the pressing plate 42 to quickly hit the ground through the lifting seat 41, thereby leveling the ground after loosening and turning over. Then, the elastic telescopic rod 51 will prompt the lifting seat 41 and the pressing plate 42 to rise and reset, so that the pressing plate 42 is set at a distance from the ground.

[0046] Afterwards, the pressure roller 43 will roll and crush the ground leveled by the pressure plate 42, thereby further leveling the ground; during the lifting process, the lifting seat 41 will drive the second gear 55 to rotate through the second rack 56, and the second gear 55 will drive the brush roller 14 to rotate back and forth on the surface of the pressure roller 43 through the fourth rotating shaft 54, thereby brushing off the soil attached to the surface of the pressure roller 43, and the brushed soil will fall back to the front of the pressure roller 43 so that the pressure roller 43 can crush this part of the soil.

[0047] In summary, the present application can loosen the soil, separate the soil from stones, clean the soil-breaking spikes 23, and efficiently level the soil through its own walking and the drive of the motor 22, which not only improves the flatness and leveling efficiency of the farmland surface, but also ensures the normal growth of crops.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
