Description

Technical Field

[0001] This utility model relates to the field of soil loosening equipment technology, specifically a soil loosening equipment. Background Technology

[0002] Soil loosening devices for landscaping and municipal engineering are specialized tools or mechanical devices used to loosen hardened soil. They typically consist of metal teeth, blades, or spiral structures, and are driven by mechanical power or human effort to turn over and break up compacted soil, improving its aeration and water permeability, and creating suitable conditions for plant root growth. Their functions include breaking up surface crusts, adjusting soil density, and promoting nutrient penetration. They are widely used in soil pretreatment for urban greening, park maintenance, lawn establishment, and municipal engineering projects, improving vegetation survival rates and reducing the labor intensity of manual soil loosening.

[0003] When the loosening teeth of a soil loosener are used for a long time, they need to be replaced in time when they are severely worn. However, after the loosening teeth are deformed by collisions with stones in the soil, they may get stuck in their installation position, making it difficult to remove them. At the same time, the fixed structure of the loosening teeth of the soil loosener means that their position cannot be adjusted. When encountering trees in the garden, it is necessary to loosen the soil around the trees, which is time-consuming and laborious. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A soil loosening device includes a mounting bracket. A drive motor is mounted on the top outer wall of the mounting bracket. A gear drive box is mounted on one end of the drive motor. A rotating shaft is mounted on the output end of the gear drive box. A fixed base is mounted on the outer wall of the rotating shaft. Two sets of fixed bases are respectively located on the outer wall of the mounting bracket. A crank is mounted on one side of the fixed base and on the outer wall of the rotating shaft. One end of the crank is rotatably connected to a toggle bracket. One end of the toggle bracket is rotatably connected to a limit plate. One end of the limit plate is rotatably connected to a positioning rod. A grip is mounted on the outer wall of the positioning rod and is disposed on the base surface of the mounting bracket. A fixing component is mounted on the outer wall of the toggle bracket. An adjustment component is mounted on one side of the fixing component and on the inner wall of the toggle bracket.

[0007] As a preferred embodiment of this utility model, the fixing component includes a fixing base, and multiple fixing bases are provided and respectively located on the outer wall of the toggle bracket. A limiting groove is formed on the inner wall of the fixing base, and a pull rod is slidably connected to the inner wall of the limiting groove. A handle is installed at one end of the pull rod, and a limiting spring is installed on the outer wall of the handle. One end of the limiting spring is connected to the inner wall of the limiting groove, and a limiting block is installed at the other end of the pull rod, wherein the limiting block is slidably connected to the inner wall of the limiting groove.

[0008] As a preferred embodiment of this utility model, an installation block is provided on one side of the limiting groove and on the inner wall of the fixed base. Two sets of installation blocks are provided and are respectively located on the inner wall of the fixed base. A tension spring is installed on the outer wall of the installation block. An ejection block is installed at one end of the tension spring. A limiting block is installed on the outer wall of the ejection block.

[0009] As a preferred embodiment of this utility model, the limiting block is located on one side of the limiting card block, and the limiting block and the limiting card block are connected by a sliding connection. The ejection card block and the limiting groove are connected by a sliding connection. Loosening teeth are sleeved on the outer wall of the fixed base, and limiting card grooves are opened on the inner walls opposite to the loosening teeth. The limiting card grooves and the ejection card block are connected by a plug-in connection.

[0010] As a preferred embodiment of this utility model, the adjustment component includes an adjustment bracket, which is disposed on the inner wall of the toggle bracket. An electrically controlled cylinder is embedded in the inner wall of the adjustment bracket, and a slide rail is installed on one side of the electrically controlled cylinder and on the inner wall opposite to the adjustment bracket.

[0011] As a preferred embodiment of this utility model, a fixed seat is slidably connected to the outer wall of the slide rail, a fixed sleeve is embedded in the outer wall of the fixed seat, a fixed rod is installed on the inner wall of the fixed sleeve, and one end of the fixed rod is connected to an electrically controlled cylinder.

[0012] As a preferred embodiment of this utility model, a bearing is embedded in the bottom outer wall of the mounting bracket, a rotating shaft is installed on the inner wall of the bearing, a roller is installed on the outer wall opposite to the rotating shaft, and a base plate is provided on the bottom outer wall of the mounting bracket.

[0013] As a preferred embodiment of this utility model, universal wheels are installed on the outer wall of the base plate, and a controller is installed on the outer wall of the drive motor. The controller is connected to the drive motor and the electric cylinder via wires, and the connection method is electrical connection. Multiple sets of fixed bases are provided and are located on the outer walls of the toggle bracket and the fixed base respectively.

[0014] This invention enables easy disassembly of the loosening teeth by setting a fixing component in the soil loosener. The handle drives the pull rod to move, which in turn moves laterally on the inner wall of the limiting groove. This causes one end of the pull rod to move the limiting block. When the limiting block moves out of the limiting block, the tension spring rebounds because the limiting block is no longer limited by the limiting block. The tension spring then causes the ejector block to rebound, causing the ejector block to move back on the inner wall of the limiting groove. This causes the ejector block to move out of the limiting slot, and the limiting slot is no longer limited by the ejector block. Then, a pulling force can be applied to pull off the loosening teeth, making installation and disassembly simpler.

[0015] This invention allows for the adjustment of the position of the loosening teeth by incorporating an adjustment component in the soil loosener. This ensures the loosening teeth are in contact with the edge of the tree for loosening. One end of the electrically controlled cylinder moves a fixed sleeve via a fixed rod, causing the fixed sleeve to move the fixed seat downwards. The fixed seat moves on the outer wall of the slide rail, causing the fixed seat to move the fixed base downwards. This creates a positional difference between the loosening teeth on the outer wall of the fixed seat and the loosening teeth on the outer wall of the actuating bracket. Consequently, the actuating bracket and the fixed seat form a concave structure, allowing the adjustment component to be moved to one side of the tree, enabling the device to loosen the soil around the tree simultaneously.

[0023] Example: Please refer to Figure 1-5 The soil loosening device shown includes a mounting bracket 1. A drive motor 2 is mounted on the top outer wall of the mounting bracket 1. A gear drive box 3 is mounted on one end of the drive motor 2. A rotating shaft 4 is mounted on the output end of the gear drive box 3. A fixed base 5 is mounted on the outer wall of the rotating shaft 4. Two sets of fixed bases 5 are provided and are located on the outer wall of the mounting bracket 1 respectively. A crank 6 is mounted on one side of the fixed base 5 and on the outer wall of the rotating shaft 4. One end of the crank 6 is rotatably connected to a toggle bracket 7. One end of the toggle bracket 7 is rotatably connected to a limit plate 8. One end of the limit plate 8 is rotatably connected to a positioning rod 9.

An adjustment component 12 is mounted on one side of the fixing component 11 and on the inner wall of the toggle bracket 7.

[0024] In this embodiment, specific references Figure 1 , Figure 2 , Figure 4 and Figure 5The fixing component 11 includes a fixing base 1101. Multiple sets of fixing bases 1101 are provided and located on the outer wall of the actuating bracket 7. A limiting groove 1102 is formed on the inner wall of the fixing base 1101. A pull rod 1103 is slidably connected to the inner wall of the limiting groove 1102. A handle 1104 is installed at one end of the pull rod 1103. A limiting spring 1105 is installed on the outer wall of the handle 1104, and one end of the limiting spring 1105 is connected to the inner wall of the limiting groove 1102. A limiting block 1106 is installed at the other end of the pull rod 1103, wherein the limiting block 1106 is slidably connected to the inner wall of the limiting groove 1102. An mounting block 1107 is provided on one side of the limiting groove 1102 and on the inner wall of the fixing base 1101. Two sets of blocks 1107 are provided and are respectively located on the inner wall of the fixed base 1101. A tension spring 1108 is installed on the outer wall of the mounting block 1107. An ejection block 1109 is installed at one end of the tension spring 1108. A limit block 1110 is installed on the outer wall of the ejection block 1109. The limit block 1110 is located on one side of the limit block 1106. The limit block 1110 and the limit block 1106 are connected by a sliding connection. The ejection block 1109 and the limit groove 1102 are connected by a sliding connection. A loosening tooth 1111 is sleeved on the outer wall of the fixed base 1101. A limit groove 1112 is opened on the inner wall opposite to the loosening tooth 1111. The limit groove 1112 and the ejection block 1109 are connected by a plug-in connection.

[0025] In this embodiment, specific references Figure 1 , Figure 2 and Figure 3 The adjustment assembly 12 includes an adjustment bracket 1201, which is disposed on the inner wall of the toggle bracket 7. An electric cylinder 1202 is embedded in the inner wall of the adjustment bracket 1201. A slide rail 1203 is installed on one side of the electric cylinder 1202 and on the inner wall opposite to the adjustment bracket 1201. A fixed seat 1204 is slidably connected to the outer wall of the slide rail 1203. A fixed sleeve 1205 is embedded in the outer wall of the fixed seat 1204. A fixed rod 1206 is installed on the inner wall of the fixed sleeve 1205. One end of the fixed rod 1206 is connected to the electric cylinder 1202.

[0026] The mounting bracket 1 has a bearing 13 embedded in its bottom outer wall, a rotating shaft 14 installed on the inner wall of the bearing 13, and a roller 15 installed on the opposite outer wall of the rotating shaft 14. The mounting bracket 1 has a base plate 16 installed on its bottom outer wall, and a caster wheel 17 installed on the outer wall of the base plate 16. The drive motor 2 has a controller 18 installed on its outer wall. The controller 18 is electrically connected to the drive motor 2 and the electric cylinder 1202 via wires, which powers the device and causes the controller 18 to control the drive motor 2 and the electric cylinder 1202 to operate. Multiple sets of fixed bases 1101 are provided and are located on the outer walls of the actuating bracket 7 and the fixed base 1204, respectively.

[0027] Based on the above structural features and connection relationship, there is a gap between the loosening tooth 1111 and the fixed base 1101 to ensure that when the loosening tooth 1111 is bumped and deformed, it will not get stuck in the fixed base 1101, and the loosening tooth 1111 is fixed by the limiting slot 1112 and the ejection block 1109.

[0028] When the soil loosener of this solution is working, turning on the switch of the controller 18 causes the controller 18 to drive the drive motor 2 to run, which in turn drives the rotating shaft 4 through the gear drive box 3. The rotating shaft 4 then selects on the inner wall of the fixed base 5. One end of the rotating shaft 4 drives the crank 6 to select, which in turn drives the actuating bracket 7 to rotate. Since one end of the actuating bracket 7 is fixed to the outer wall of the positioning rod 9 through the limiting plate 8, the actuating bracket 7 moves back and forth downward, which causes the loosening teeth 1111 to reciprocate and insert into the soil to loosen the soil.

[0029] By turning on the switch of the controller 18, the controller 18 controls the operation of the electric cylinder 1202, causing one end of the electric cylinder 1202 to move the fixed sleeve 1205 via the fixed rod 1206. This causes the fixed sleeve 1205 to move the fixed seat 1204 downwards. The fixed seat 1204 moves on the outer wall of the slide rail 1203, causing the fixed seat 1204 to move the fixed base 1101 downwards. This creates a positional difference between the loosening teeth 1111 on the outer wall of the fixed seat 1204 and the loosening teeth 1111 on the outer wall of the actuating bracket 7. This causes the actuating bracket 7 and the fixed seat 1204 to form a concave structure, allowing the adjusting component 12 to be moved to one side of the tree. This allows the device to loosen the soil around the tree simultaneously, thus solving the problem that the position of the loosening teeth cannot be adjusted, and that it is time-consuming and laborious to loosen the soil around the tree when encountering trees in a garden.

[0030] When the loosening tooth 1111 needs to be replaced, the handle 1104 can be squeezed and stretched, causing the handle 1104 to move the pull rod 1103. This causes the pull rod 1103 to move laterally on the inner wall of the limiting groove 1102, which in turn causes one end of the pull rod 1103 to move the limiting block 1106. When the limiting block 1106 moves out of the limiting block 1110, the limiting block 1110 loses the limiting position of the limiting block 1106, causing the tension spring 1108 to rebound, thereby... The tension spring 1108 drives the ejector block 1109 to rebound, causing the ejector block 1109 to move back on the inner wall of the limiting groove 1102, thereby causing the ejector block 1109 to move out of the limiting groove 1112. This removes the limiting groove 1112 from the limiting position of the ejector block 1109, allowing the application of tension to pull off the loosening tooth 1111. This simplifies installation and disassembly, thus solving the problem that after the loosening tooth is deformed by collision with stones in the soil, it will get stuck in the installation position, making it difficult to disassemble.

Their structure, circuit, and control principle are all existing known technologies. Therefore, the structure, circuit, and control principle of the drive motor 2, the electronically controlled cylinder 1202, and the controller 18 will not be described in detail here.
