Technical Field
[0001] The utility model relates to the field of greening construction, in particular to a soil loosening device for greening construction. Background Art
[0002] In the process of landscaping planting, it is often necessary to use greening construction loosening devices to loosen the soil, so as to improve the soil structure, provide the air, water and nutrients required for plant growth, promote root growth and development, and increase the quality of plants.
[0003] Traditional soil loosening devices for greening construction still have certain shortcomings during use: most of the current soil loosening equipment is a hand-pushed trolley type, on which is installed a soil loosening blade driven by a motor. The soil loosening work is completed by breaking up the compacted soil on the surface with the rotating blade. However, there are two problems with this type of soil loosening equipment. First, when loosening the soil on a hard ground, it is easier to use normal wheels to assist the movement of the equipment, but on a soft ground, a structure with stronger grip is required. The current equipment is not convenient for adjusting the wheel structure according to the soil type; second, the soil loosening blade will raise a lot of dust when working. Although the current soil loosening equipment is equipped with a mudguard, the shielding effect cannot meet the requirements.
[0004] Therefore, it is necessary to provide a new soil loosening device for greening construction to solve the above technical problems. Utility Model Content
[0005] The technical problem solved by the utility model is to provide a soil loosening device for greening construction which has a good soil retaining structure and can adjust the wheel structure according to the soil type.
[0006] In order to solve the above technical problems, the utility model provides a soil loosening device for greening construction, comprising: a support frame, a wheel assembly and a soil retaining assembly, the wheel assembly comprising a first wheel, the first wheel is rotatably connected to the support frame, the surface of the first wheel is fixedly connected to an axle body, the surface of the axle body is provided with a key groove, the outer side of the axle body is provided with a second wheel, the second wheel is fixedly connected to a positioning block, the positioning block is slidably connected to the key groove, a return spring is provided on the outer side of the axle body between the first wheel and the second wheel, a nut is threadedly connected to the end of the axle body, a gasket is provided between the nut and the second wheel, the surfaces of the sides relatively close to the first wheel and the second wheel are both rotatably connected to movable plates, and a plurality of movable plates are evenly distributed around the axis, and a connecting block is rotatably connected between two adjacent movable plates;
[0007] A fixing piece is fixedly connected to the surface of the support frame, a limiting block is fixedly connected to the surface of the fixing piece, the retaining assembly includes a retaining shell, a limiting groove is provided on the surface of the retaining shell, the limiting groove is slidably connected to the limiting block, a spring rod is hinged between the fixing piece and the retaining shell, and a roller is rotatably connected to the bottom of the retaining shell.

[0009] Through the above technical solution, when loosening the soil on the ground with hard soil, it is easier to use normal wheels to assist the movement of the equipment, but on the ground with soft soil, a structure with stronger grip is required. Traditional equipment is not convenient to adjust the wheel structure according to the soil type. In the device, under normal conditions, the cooperation of the first wheel and the second wheel can allow the trolley to move smoothly.

At this time, the two sets of movable plates change angles and lift up the fixed blocks. The movement of the trolley is achieved by a number of fixed blocks evenly distributed around the axis. Since the surface of the fixed block is provided with teeth and grooves and the structure is smaller than the tire, it is easier to break the soil and insert into the ground. The structural design makes the trolley have stronger grip during the movement, allowing the trolley to achieve stable movement.
[0010] As a further solution of the utility model, a cantilever is fixedly connected to the surface of the fixed part located on the inner side of the retaining shell, the end of the cantilever is rotatably connected to a rotating part, the interior of the rotating part is rotatably connected to a roller shaft, a plurality of loosening blades arranged at equal intervals are installed on the surface of the roller shaft, and a telescopic cylinder is rotatably connected between the fixed part and the rotating part.
[0011] Through the above technical scheme, the loosening blade will raise a lot of dust when working. Although the traditional loosening equipment is equipped with a mudguard, the shielding effect cannot meet the requirements. The device is equipped with a fixing and a retaining shell on the outside of the loosening blade. Except for the bottom which is open, the other directions are closed, so as to effectively block the dust thrown up inside. In addition, the retaining shell in the structure can move up and down along the limit block, and is equipped with rollers at the bottom, so that when the trolley moves forward, the retaining shell can adapt to the change of the ground slope and complete the height adjustment by itself, and always maintain an appropriate distance from the ground, blocking the dust to be turned over without setting the height in advance. The structural design is humanized and easy to operate.
[0012] As a further solution of the utility model, a large sprocket is fixedly connected to the end of the roller shaft, a small sprocket is rotatably connected to the surface of the rotating member, and the small sprocket is connected to the large sprocket via a chain.
[0013] Through the above technical solution, the driving motor transfers the kinetic energy of one side of the small sprocket to the large sprocket through the chain, and then transfers the kinetic energy to the loosening blade on the roller shaft to achieve soil breaking and loosening work.
[0014] As a further solution of the utility model, a driving motor is installed at the end of the small sprocket, an engine is installed on the surface of the support frame, a control module is installed on the surface of the mounting part on one side, and the driving motor, telescopic cylinder and engine are all electrically connected to the control module.
[0015] Through the above technical solution, the control module is set on one side of the handrail. When the user pushes the trolley to move, he can control the various electrical appliances in the structure through the control module to complete the loosening work.
[0016] As a further solution of the utility model, the width of the retaining shell matches the width of the fixing member, the bottom of the retaining shell is configured as an open structure, and the loosening blade extends to the outside through the opening at the bottom of the retaining shell.
[0017] Through the above technical solution, the bottom of the retaining shell is set as an open structure, so that the loosening blade can contact the ground and complete the work of breaking and loosening the soil, and the structural design is reasonable.
[0018] As a further solution of the utility model, a fixing block is fixedly connected to the surface of the connecting block, and a tooth groove is formed on the surface of the fixing block.
[0019] Through the above technical solution, compared with the wheel structure, the fixed block has a sharper shape, is easier to break through the soil and insert into the soft ground, and has a strong grip.
[0020] Compared with the related art, the soil loosening device for greening construction provided by the utility model has the following beneficial effects:
[0021] 1. In the utility model, when loosening the soil on the ground with hard soil, it is easier to use normal wheels to assist the movement of the equipment. However, on the ground with soft soil, a structure with stronger grip is required. It is not convenient to adjust the wheel structure according to the soil type for traditional equipment. In the device, under normal conditions, the cooperation of the first wheel and the second wheel can make the trolley move smoothly. When encountering the ground with soft soil, the nut is tightened with a wrench or other tools to compress the return spring and move horizontally to one side. At this time, the two sets of movable plates change their angles and lift up the fixed blocks. The movement of the trolley is achieved by a number of fixed blocks evenly distributed around the axis. Since the surface of the fixed block is provided with tooth grooves and the structure is smaller than that of the tire, it is easier to break the soil and insert into the ground. The structural design makes the trolley have stronger grip during the movement, so that the trolley can achieve stable movement.

The bottom heights of the first wheel 21 and the second wheel 22 are lower than the bottom height of the support frame 1.
[0034] When loosening the soil on a hard ground, it is easier to use normal wheels to assist the movement of the equipment. However, on a soft ground, a structure with stronger grip is required. It is not convenient to adjust the wheel structure of traditional equipment according to the soil type. In the device, under normal conditions, the cooperation of the first wheel 21 and the second wheel 22 can allow the trolley to move smoothly. When encountering a soft ground, tighten the nut 27 with a wrench or other tool to compress the return spring 24 and move it to one side. At this time, the two sets of movable plates 23 change their angles and lift up the fixed blocks 26. The movement of the trolley is achieved by a number of fixed blocks 26 evenly distributed around the axis. Since the surface of the fixed block 26 is provided with teeth and grooves and the structure is smaller than that of the tire, it is easier to break the soil and insert into the ground.

[0036] The loosening blade 11 will raise a lot of dust when working. Although the traditional loosening equipment is equipped with a mudguard, the shielding effect cannot meet the requirements. The device is equipped with a fixing 15 and a retaining shell 8 on the outside of the loosening blade 11. Except for the bottom which is open, the other directions are closed designs, thereby effectively blocking the dust thrown up inside. In addition, the retaining shell 8 in the structure can move up and down along the limit block 16, and is equipped with rollers 9 at the bottom, so that when the trolley moves forward, the retaining shell 8 can adapt to the changes in the ground slope and complete the height adjustment by itself, and always maintain an appropriate distance from the ground, blocking the dust that will be turned over without setting the height in advance. The structural design is user-friendly and easy to operate.
[0037] like Figure 1-4 As shown, a large sprocket 13 is fixedly connected to the end of the roller shaft 12, and a small sprocket 14 is rotatably connected to the surface of the rotating member 19. The small sprocket 14 is connected to the large sprocket 13 via a chain.
[0038] The driving motor 20 transfers the kinetic energy of one side of the small sprocket 14 to the large sprocket 13 through the chain, and then transfers the kinetic energy to the loosening blade 11 on the roller shaft 12 to achieve soil breaking and loosening work.
[0039] like Figure 1-4 As shown, a driving motor 20 is installed at the end of the small sprocket 14, an engine 2 is installed on the surface of the support frame 1, and a control module 7 is installed on the surface of the mounting member 6 on one side. The driving motor 20, the telescopic cylinder 17 and the engine 2 are all electrically connected to the control module 7.
[0040] The control module 7 is arranged on one side of the handrail. When the user pushes the trolley to move, he can control various electrical appliances in the structure through the control module 7 to complete the soil loosening work.

[0042] The bottom of the retaining shell 8 is set to an open structure, so that the loosening blade 11 can contact the ground and complete the work of breaking and loosening the soil. The structural design is reasonable.
[0043] like Figure 1-4 As shown, a fixing block 26 is fixedly connected to the surface of the connecting block, and a tooth groove is formed on the surface of the fixing block 26.
[0044] Compared with the wheel structure, the fixing block 26 has a sharper shape, is easier to break through the soil and insert into the soft ground, and has a strong grip.
[0045] The working principle of a soil loosening device for greening construction provided by the utility model is as follows:
[0046] Step 1: When loosening the soil on a hard ground, it is easier to use normal wheels to assist the movement of the equipment. However, on a soft ground, a structure with stronger grip is required. It is not convenient to adjust the wheel structure of traditional equipment according to the soil type. In the device, under normal conditions, the cooperation of the first wheel 21 and the second wheel 22 can allow the trolley to move smoothly. When encountering a soft ground, tighten the nut 27 with a wrench or other tools to compress the return spring 24 and move it to one side. At this time, the two sets of movable plates 23 change their angles and lift up the fixed blocks 26. The movement of the trolley is achieved by a number of fixed blocks 26 evenly distributed around the axis. Since the surface of the fixed block 26 is provided with teeth and grooves and the structure is smaller than that of the tire, it is easier to break the soil and insert into the ground. The structural design makes the trolley have stronger grip during the movement, so that the trolley can achieve stable movement.
[0047] The second step: the loosening blade 11 will raise a lot of dust when working. Although the traditional loosening equipment is equipped with a mudguard, the shielding effect cannot meet the requirements. The device is equipped with a fixing part 15 and a retaining shell 8 on the outside of the loosening blade 11. Except for the bottom which is open, the other directions are closed, so as to effectively block the dust thrown up inside. In addition, the retaining shell 8 in the structure can move up and down along the limit block 16, and is equipped with rollers 9 at the bottom, so that when the trolley moves forward, the retaining shell 8 can adapt to the changes in the ground slope and complete the height adjustment by itself, and always maintain an appropriate distance from the ground, blocking the dust that will be turned over without setting the height in advance. The structural design is humanized and easy to operate.
