DETAILED DESCRIPTION

[0034] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] Embodiment 1:

[0037] A soil improvement device, such as Figures 1 to 9 As shown, it includes a bracket part, both ends of the bracket part are rotatably connected with a damping shaft 13, and the outer walls of the two damping shafts 13 are fixed with pulleys 20 by pins, and the outer walls of the two pulleys 20 are transmission-connected with a moving belt 2, a leak hole 8 is opened on the moving belt 2, and the inner surface of the moving belt 2 is integrally formed with a plurality of groups of limit blocks 9, the outer wall of the bracket part is slidably connected with a moving seat 17, and both ends of the moving seat 17 are fixed with a lifting support assembly, and the top of the moving seat 17 is fixed with a box by bolts The bottom of the box body 6 and the bottom of the movable seat 17 are both provided with liquid outlet holes 18 that are connected to each other. The outer wall of the bottom of the movable seat 17 is fixed with a side plate 19 by bolts, and a rotating rod 27 is rotatably connected between the two side plates 19, and a torsion spring 1 26 is clamped between the circumferential outer wall of the rotating rod 27 and the outer wall of one side of the side plate 19, and a triangular plate 24 used in conjunction with the limit block 9 is fixed to the circumferential outer wall of the rotating rod 27, and a contact plate 25 is fixed between the two side plates 19 by screws;

[0038] When it is necessary to improve the soil, the improved liquid can be stored in the box 6. A filling pipe is installed on the top of the box 6 to facilitate the filling and replenishment of the improved liquid. When the improved liquid needs to be introduced into the soil, when the bracket part contacts the ground surface, the box 6 and the movable seat 17 are slid along the bracket part as a whole. The liquid outlet 18 at the bottom of the box 6 and the movable seat 17 slide along the top outer wall of the moving belt 2. When the liquid outlet 18 moves to a relative opening between the liquid outlet 18 and the leakage hole 8, the improved liquid in the box 6 falls into the soil through the liquid outlet 18 and the leakage hole 8, thereby improving the soil. In addition, since the box 6 and the movable seat 17 continuously move along the bracket part during this process, the improved liquid can improve the soil at different positions, ensuring that the improved liquid falls into the soil more evenly.

[0039] When the box body 6 and the moving seat 17 move along the bracket part, the triangular plate 24 moves synchronously along the inner wall of the top of the moving belt 2. In this embodiment, the longitudinal section of the triangular plate 24 is a right triangle. Therefore, when the triangular plate 24 moves along the inner wall of the top of the moving belt 2, the inclined surface of the triangular plate 24 will intermittently contact the surface of the limit block 9. In order to avoid the triangular plate 24 from getting stuck, a rotation connection is set between the rotating rod 27 and the side plate 19, so that when the inclined surface of the triangular plate 24 moves to the limit block 9, it slides along the surface of the limit block 9, so that the triangular plate 24 can pass through the limit block 9 and move normally. When the triangular plate 24 and the limit block 9 are separated from each other, the resilience of the torsion spring 1 26 is used to ensure that the triangular plate 24 can be reset.

[0040] When the box body 6 and the moving seat 17 move from one end of the bracket to the other end, an improvement cycle is completed. At this time, the entire device needs to be pushed forward to improve the soil in other areas. By providing a lifting support assembly, the box body 6, the moving seat 17 and the bracket are lifted as a whole when rising, so that the bottom of the bracket and the ground are separated from each other and are in a suspended state. At this time, the bracket is slid forward along the moving seat 17. In this process, one of the limit blocks 9 on the inner surface of the moving belt 2 will eventually interfere with the movement. On the vertical surface behind the triangular plate 24, the contact plate 25 is used to support and limit the triangular plate 24, ensuring that the triangular plate 24 remains stable after the limit block 9 contacts the vertical surface behind the triangular plate 24. When the limit block 9 and the triangular plate 24 are in relative contact, the liquid outlet 18 and the leakage hole 8 on the moving belt 2 are in mutually dislocated positions, that is, the moving belt 2 blocks the liquid outlet 18, preventing the improved liquid from overflowing from the liquid outlet 18 during the forward movement of the bracket part, thereby causing waste in the liquid outlet 18.

[0041] During the forward movement of the bracket, the damping shaft 13 and the pulley 20 will rotate relative to the bracket, thereby ensuring that the moving belt 2 always keeps covering the liquid outlet 18 until the bracket moves forward to the maximum distance. Through this structure and movement mode, the entire device can move in a manner similar to creeping, so as to improve the soil in different areas. At the same time, it can effectively replace traditional valves and other components. By adjusting the relative positions of the moving belt 2, the leakage hole 8 and the liquid outlet 18, the retention of the improved liquid can be controlled, thereby improving the operating efficiency and reducing the waste of the improved liquid.

[0042] The bracket part includes a mounting plate 1, a lead screw 3 and a guide rod 7, the guide rod 7 is fixed between two of the mounting plates 1, and the lead screw 3 is rotatably connected between the other two mounting plates 1, and the movable seat 17 and the guide rod 7 are slidably connected, and a nut used in conjunction with the lead screw 3 is installed on the surface of the movable seat 17, the damping shaft 13 is rotatably connected between the two mounting plates 1 on the same side, a driving motor 12 is fixed to the outer wall of one side of one of the mounting plates 1 by bolts, and the output end of the driving motor 12 is connected to one end of the lead screw 3 by a coupling, and the bracket part also includes a universal wheel 11 rotatably connected to the bottom of the mounting plate 1;

[0043] By providing a universal wheel 11, the equipment can be easily moved on the ground after the soil improvement is completed, thereby improving its portability. By providing a drive motor 12, the lead screw 3 can be driven to rotate, so that the movable seat 17 can move laterally under the guidance of the guide rod 7, so that the improvement liquid can be introduced into the soil in different areas through the liquid outlet 18.

[0044] The lifting support assembly includes an electric telescopic rod 5 and a fixed plate 43, wherein the fixed plate 43 is fixed to the side wall of the movable seat 17 by bolts, and the electric telescopic rod 5 is fixed to the top outer wall of the fixed plate 43 by bolts, and the output end of the electric telescopic rod 5 is fixed to the support plate 4 by a pin, and a plurality of groups of pins 10 are welded to the bottom of the support plate 4;

[0045] When the bracket part needs to move forward after completing an improvement cycle, when the electric telescopic rod 5 controls the support plate 4 to move to contact with the ground, when the output end of the electric telescopic rod 5 continues to extend, the box body 6 and the movable seat 17 are lifted as a whole, thereby facilitating the movement of the bracket part in a suspended state. By providing the insertion pin 10, the stability of the support of the lifting support assembly is improved after it is inserted below the ground surface.

[0046] A rotating rod 21 is rotatably connected between the two side plates 19, and a torsion spring 28 is installed between the circumferential outer wall of the rotating rod 21 and the side plate 19, and a resistance rod 23 is welded between the two side plates 19, and a mounting frame 15 is fixed to the circumferential outer wall of the rotating rod 21, and an arc block 22 used in conjunction with the limit block 9 is integrally formed at one end of the mounting frame 15, and a loosening claw 16 is welded at the other end of the mounting frame 15;

[0047] Before introducing the improvement liquid into the soil, the soil needs to be loosened to ensure sufficient contact between the improvement liquid and the soil. When the movable seat 17 moves laterally along the bracket part, the loosening claw 16 loosens the soil during the synchronous movement. During this process, the arc block 22 will intermittently move and contact each other with the limit block 9. When the arc block 22 moves to the limit block 9, the limit block 9 blocks the arc block 22, causing the rotating rod 21 to rotate relative to the side plate 19. Since the distance between the rotating rod 21 and the end of the arc block 22 is smaller than the distance between the rotating rod 21 and the loosening claw 16, the lever principle is used to make the arc block 22 swing relatively to the limit block 9 with a smaller amplitude, and the loosening claw 16 swing relatively to the soil with a larger amplitude, so that when loosening the soil, the loosening claw 16 can also swing back and forth under the rebound force of the torsion spring 28 while moving forward, thereby increasing the motion range of the loosening claw 16, thereby improving the loosening effect.

[0048] When the present embodiment is in use, the improvement liquid is stored in the box body 6. When the soil needs to be improved, the bracket part is placed on the ground surface and the movable seat 17 is operated to slide along the bracket part. The liquid outlet hole 18 at the bottom of the box body 6 and the movable seat 17 will slide along the top outer wall of the movable belt 2. When a relative opening is generated between the liquid outlet hole 18 and the leakage hole 8 on the movable belt 2, the improvement liquid falls into the soil through the liquid outlet hole 18 and the leakage hole 8 to achieve soil improvement. Since the movable seat 17 continuously moves along the bracket part, the improvement liquid can evenly improve the soil at different positions. During the movement of the movable seat 17, the triangular plate 24 moves synchronously along the top inner wall of the movable belt 2. The longitudinal section of the triangular plate 24 is a right triangle, and its inclined surface will intermittently contact the surface of the leakage hole 8. In order to prevent the triangular plate 24 from getting stuck, a rotating connection is set between the rotating rod 27 and the side plate 19. When the inclined surface of the triangular plate 24 moves to the leakage hole 8, it will slide along the surface of the leakage hole 8 and pass normally. When the triangular plate 24 is separated from the leakage hole 8, the rebound force of the torsion spring 1 26 resets the triangular plate 24. When an improvement cycle is completed, the equipment needs to move forward to improve the soil in other areas. At this time, the box body 6, the moving seat 17 and the bracket part are lifted as a whole through the lifting support assembly, so that the bottom of the bracket part The bracket is separated from the ground and is in a suspended state, and then the bracket part slides forward along the moving seat 17. During this process, the limit block 9 on the inner surface of the moving belt 2 will abut against the vertical surface behind the triangular plate 24, and the abutment plate 25 is used to support and limit the triangular plate 24. When the limit block 9 and the triangular plate 24 abut against each other, the liquid outlet 18 and the leakage hole 8 on the moving belt 2 are in mutually displaced positions, that is, the moving belt 2 blocks the liquid outlet 18 to prevent the improved liquid from overflowing. During the forward movement of the bracket part, the damping shaft 13 and the pulley 20 will rotate relative to the bracket part, thereby ensuring that the moving belt 2 always keeps blocking the liquid outlet 18 until the bracket part is When the movable seat 17 moves laterally along the bracket part, the loosening claw 16 moves synchronously and loosens the soil. The arc block 22 will intermittently contact the limit block 9. When the arc block 22 moves to the limit block 9, the limit block 9 blocks it, so that the rotating rod 21 rotates relative to the side plate 19. When the arc block 22 swings a smaller amplitude relative to the limit block 9 by utilizing the lever principle, the loosening claw 16 swings a larger amplitude relative to the soil. Under the rebound force of the torsion spring 28, the loosening claw 16 swings back and forth while moving forward, thereby improving the loosening effect.

[0049] Embodiment 2:

[0050] A soil improvement device, such as Figures 1 to 9As shown, in order to improve the spraying range of the improved liquid, this embodiment makes the following supplements on the basis of embodiment 1: a spray assembly is installed at the bottom of the movable seat 17, and the spray assembly includes a liquid inlet cylinder 31 and a connecting rod 32, the connecting rod 32 is welded to the outer wall of the bottom of the movable seat 17, and the liquid inlet cylinder 31 is fixed between the two connecting rods 32, and an annular groove 33 is provided on the circumferential inner wall of the liquid inlet cylinder 31, and a rubber tube 14 is installed at the bottom of the liquid inlet cylinder 31, and a guide hole 34 is provided on the circumferential outer wall of the rubber tube 14, and a rubber tube 14 is integrally formed on the circumferential outer wall The rubber rib 35, the inner wall of the circumference of the liquid inlet cylinder 31 is fixed with a connecting block 42 by screws, and a sleeve 30 is fixed between the two connecting blocks 42, the through hole opened at the top of the sleeve 30 is slidably connected with a slide rod 37, and a round table 29 is fixed on the top of the slide rod 37, an extrusion disk 40 is fixed at the bottom of the round table 29, and a middle hole 41 is opened on the surface of the extrusion disk 40, a sponge pad 36 is bonded to the bottom of the extrusion disk 40, a pressure plate 38 is fixed to the outer wall of the circumference of the slide rod 37, and a spring 39 is clamped between the outer wall of the bottom of the pressure plate 38 and the inner wall of the bottom of the sleeve 30;

[0051] When the improved liquid needs to be introduced into the soil, in the initial stage, when the truncated cone 29 and the leakage hole 8 are in a facing position, the top height of the truncated cone 29 is higher than the top outer wall of the moving belt 2, and the truncated cone 29 blocks the top of the liquid inlet cylinder 31 to prevent the improved liquid from overflowing. When the box body 6 and the moving seat 17 move laterally along the bracket part, the moving seat 17 drives the spraying assembly to move synchronously. Since the truncated cone 29 is a conical structure, when the truncated cone 29 moves from the inside of the leakage hole 8 to the top inner wall of the moving belt 2, the moving belt 2 squeezes the truncated cone 29 in the longitudinal direction. After being squeezed, the truncated cone 29 moves down along the liquid inlet cylinder 31. When the truncated cone 29 moves to the annular groove 33, a gap is generated between the truncated cone 29 and the annular groove 33, so that the improved liquid is introduced into the inside of the liquid inlet cylinder 31 through the gap, and the improved liquid finally passes through the middle hole 41 soaks the sponge pad 36, and at the same time, the round table 29 is squeezed to drive the sliding rod 37, the squeezing plate 40 and the sponge pad 36 to move downward. When the sponge pad 36 moves to the inner wall of the bottom of the liquid inlet cylinder 31, the sponge pad 36 is continuously squeezed, so that the improved liquid enters the rubber tube 14 after being squeezed, and is finally sprayed through the outlet hole 34. Since the height of the bottom of the rubber tube 14 is lower than the height of the outer wall of the bottom of the moving belt 2, the rubber tube 14 will intermittently move to the inside of the leakage hole 8 during the lateral movement. The leakage hole 8 will block the rubber tube 14, so that the rubber tube 14 will be deformed during the lateral movement. During the deformation of the rubber tube 14, the improved liquid is sprayed in different directions through the outlet hole 34, thereby increasing the spraying range of the improved liquid.

Any modification, equivalent substitution and improvement made by any technician familiar with the field within the technical scope disclosed by the present invention in combination with the prior art or public common sense, within the spirit and principle of the present invention, shall be covered by the protection scope of the present invention.
