Description

Technical Field

[0001] This utility model belongs to the field of greening construction technology, specifically, it relates to a leveling device for greening construction. Background Technology

[0002] In greening projects, the precision of soil leveling directly impacts the quality of subsequent planting and the overall landscape effect. Traditional leveling relies on manual labor, involving loosening the soil with hoes and rakes followed by pressing and leveling with scrapers. This process lacks standardized criteria for judging levelness and depth control, depending entirely on the operator's experience. This method easily leads to large errors in soil surface flatness, with uneven pressure causing localized bulges or depressions. Subsequent planting can result in inconsistent plant heights, root rot from water accumulation in depressions, or root penetration difficulties due to thin soil layers in bulges. Ultimately, this reduces the overall quality of the greening project and the survival rate of the vegetation, failing to meet the standardized and precise operational requirements of modern greening construction.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] Example 1:

[0029] like Figures 1 to 5 As shown, a leveling device for greening construction includes a frame 1 and a load-bearing frame 2 fixedly connected to the bottom of the frame 1. A housing 6 is fixedly installed inside the frame 1, and an electrical control box 7 is fixedly installed on the top of the housing 6.

[0030] The frame 1 is equipped with a lifting mechanism, which includes a cylinder 8, a telescopic rod 9, a balance plate 10, and a pressure plate 11. The telescopic rod 9 is connected to the output end of the cylinder 8, the balance plate 10 is fixedly connected to the bottom of the telescopic rod 9, and the pressure plate 11 is fixedly connected to the bottom of the balance plate 10. A displacement sensor 12 is installed on the front of the cylinder 8, and a rubber anti-slip pad is provided on the bottom of the pressure plate 11. The surface of the rubber anti-slip pad is provided with a diamond-shaped anti-slip pattern, and the rubber anti-slip pad is detachably connected to the pressure plate 11 by bolts.

[0031] The bottom of the balance plate 10 is provided with a loosening mechanism, which includes a motor 13, a rotating shaft 14, a turntable 15 and loosening teeth 16. The motor 13 is fixedly installed on the top of the housing 6, the rotating shaft 14 is connected to the output end of the motor 13, the turntable 15 is fixedly connected to the bottom end of the rotating shaft 14, and the loosening teeth 16 are connected to the bottom of the turntable 15. The center of the balance plate 10 has a through hole with a diameter larger than that of the rotating shaft 14, the rotating shaft 14 passes through the through hole, and the loosening teeth 16 are evenly distributed at the bottom of the turntable 15.

[0032] A collection box 17 is fixedly connected to the bottom of the turntable 15, an annular filter screen 18 is fixedly connected to the inner wall of the collection box 17, and a micro pump 19 is fixedly installed on the top of the collection box 17.

[0033] The diameter of the holes in the annular filter screen 18 is set to 5-8mm. The top of the screen is flush with the top of the collection box 17, and the bottom extends to be flush with the top of the loosening teeth 16. The micro pump 19 is a negative pressure suction pump, which can create a negative pressure environment inside the collection box 17 after starting. When the loosening teeth 16 rotate to loosen the soil, the impurities generated are blocked by the annular filter screen 18. The negative pressure airflow will adsorb the impurities on the inner wall of the annular filter screen 18, while simultaneously sucking fine dust into the collection box 17, preventing impurities from accumulating on the filter surface and affecting the filtration efficiency, thus achieving the separate collection of impurities and dust.

[0034] Cylinder 8 is a single-rod double-acting cylinder, displacement sensor 12 is a laser displacement sensor, balance plate 10 is made of Q235 steel plate, motor 13 is a three-phase asynchronous motor, loose gear 16 is made of 65Mn spring steel, electrical control box 7 has a built-in PLC controller, level 5 is a digital level, universal wheel 3 is made of polyurethane material, electrical control box 7 has a built-in collaborative control program, and pressure plate 11 has a rubber anti-slip pad at the bottom.

[0035] The bottom of the load-bearing frame 2 is equipped with casters 3, the right side of the frame 1 is fixedly connected with a push rod 4, the top of the frame 1 is fixedly installed with a level 5, the electrical control box 7 is equipped with a touch screen and an emergency stop button, the touch screen is electrically connected to the displacement sensor 12 and the cylinder 8, and the emergency stop button can cut off the main power supply of the device.

[0036] Example 2:

[0037] Based on Embodiment 1, a positioning pin 20 is fixedly connected to the bottom of the turntable 15, a buckle 21 is engaged at the bottom of the positioning pin 20, and a buffer spring 22 is fixed at the bottom of the buckle 21.

[0038] Align the top of the buckle 21 with the bottom of the positioning pin 20, apply axial force to make the buckle 21 elastically open and snap into the slot of the positioning pin 20, thus completing the positioning and fixing of the loose tooth 16 and the turntable 15, and the buffer spring 22 is in a free extension state.

[0039] During the normal loosening stage, the loosening tooth 16 rotates and inserts into the soil, while the buffer spring 22 remains slightly compressed. The elastic force keeps the loosening tooth 16 tightly attached to the soil, ensuring uniform loosening depth. When the loosening tooth 16 encounters hard resistance such as stones, the reaction force is transmitted upward, pushing the buffer spring 22 to compress. The spring deformation absorbs the impact force, and at the same time, the snap-fit ​​structure between the buckle 21 and the positioning pin 20 prevents the loosening tooth 16 from falling off.

[0040] Example 3:

[0041] Based on Examples 1 and 2, please refer to Figures 6-7 A load-bearing plate 23 is fixedly connected to the outer surface of the turntable 15. A medicine tank 24 and a spray pump 25 are fixedly installed on the top of the load-bearing plate 23. A spray pipe 26 is fixedly connected to the side of the load-bearing plate 23 away from the turntable 15. A motor 27 is fixedly installed on the side of the load-bearing plate 23. A drive shaft 28 is connected to the output end of the motor 27. A plow plate 29 is fixedly connected to the outer surface of the drive shaft 28.

[0042] The motor 27 on the side of the load-bearing plate 23 is started. The output end of the motor 27 drives the drive shaft 28 to rotate, which in turn causes the plow plate 29 on the outer surface of the drive shaft 28 to rotate synchronously. The plow plate 29 moves with the device and inserts into the soil surface, breaking up large clods of soil and compacted soil in advance and combing them into uniform soil strips. At the same time, it can initially divide the soil working area, reducing resistance for the subsequent deep loosening of the loosening teeth 16 and avoiding wear or jamming of the loosening teeth 16 due to direct contact with large clods of hard soil.

[0043] If shallowly buried stones or roots are encountered on the soil surface, the lateral force generated by the rotation of the plow plate 29 can initially remove them to the soil surface, making it easier for subsequent manual cleaning.

[0044] After the loosening operation is completed, cylinder 8 pushes the telescopic rod 9 downward according to preset parameters, causing the balance plate 10 and the bottom pressure plate 11 to descend synchronously. The rubber anti-slip pad at the bottom of the pressure plate 11 comes into contact with the loosened soil, pressing and leveling the soil evenly.

[0045] While the leveling work is underway, the spray pump 25 on top of the load-bearing plate 23 is started. The spray pump 25 pressurizes the agents in the medicine tank 24, such as soil conditioner, pest and disease control agents, and water-retaining agents, and then sprays them evenly onto the leveled soil surface through the spray pipe 26 on the side of the load-bearing plate 23 away from the turntable 15.

[0046] Working principle:

[0047] Push the push rod 4 and move the device to the construction area with the help of the casters 3 at the bottom of the load-bearing frame 2; step on the foot pedal of the brake mechanism of the casters 3 to make the brake pads fit against the wheel body, fix the position of the device and prevent it from shifting during operation.

[0048] The speed of motor 13 is set by the touch screen of the control box 7. After the motor 13 is started, the output end of the motor 13 drives the rotating shaft 14 to rotate, which in turn makes the turntable 15 and the loosening teeth 16 at the bottom rotate synchronously. The loosening teeth 16 are inserted into the soil to break up and loosen the compacted soil, laying the foundation for subsequent leveling operations. During the operation, a large area of ​​soil loosening can be achieved by moving the device.

[0049] After loosening, the extension distance of cylinder 8 is set via the touch screen, and displacement sensor 12 monitors the displacement data of extension rod 9 in real time and transmits the data to the touch screen. Cylinder 8 pushes extension rod 9 downward, causing balance plate 10 and pressure plate 11 to descend synchronously. The rubber anti-slip pad at the bottom of pressure plate 11 contacts the loosened soil and presses it to level it. If level 5 shows local tilt, the extension amount of cylinder 8 in the corresponding area can be adjusted via the touch screen, so that pressure plate 11 presses more on the higher soil and less on the lower soil, until level 5 shows horizontal, completing the leveling of that area. If continuous operation is required, release the brake of caster wheel 3, move the device to the next area, and repeat the above loosening and leveling steps.

[0050] Before starting the loosening mechanism, the micro pump 19 is turned on through the electrical control box 7 to create a stable negative pressure inside the collection box 17. The motor 13 drives the rotating shaft 14, the turntable 15 and the loosening teeth 16 to rotate. The loosening teeth 16 insert into the soil and break up the compacted layer. The soil and impurity mixture is carried to the inside of the annular filter screen 18 by the rotational force. Fine soil particles fall to the working surface through the mesh of the filter screen. Impurities such as gravel and grass roots are blocked by the filter screen and adhere to the inner wall of the filter screen or are sucked into the dust collection chamber under the action of negative pressure.

[0051] If any abnormality occurs during operation, such as motor 13 jamming or cylinder 8 malfunctioning, pressing the emergency stop button on the electrical control box 7 will immediately cut off the main power supply to the device, stop all mechanisms from operating, and ensure the safety of the equipment and operators.
