Description

Technical Field

[0001] This utility model belongs to the field of rammed earth equipment technology, specifically relating to a rammed earth device for land leveling projects. Background Technology

[0002] Rammed earth, as a verb, means to compact soil by tamping it down; as a noun, it refers to a material used in ancient Chinese architecture, a solid, dense, and tightly packed block of rammed earth used for building construction. In land leveling projects, rammed earth equipment is indispensable. By using rammed earth equipment, the surface condition of the land is modified, and significant differences in elevation between different parts of the land are reduced to meet the requirements of subsequent construction.

[0003] Existing ramming devices for land leveling projects are limited by their structure and design, and can only perform repeated ramming operations. Their function is singular. Moreover, their fixed structural design makes it difficult to adjust the ramming force, and it is difficult to adjust the ramming force for different degrees of soil looseness. For excessively loose soil, more ramming operations are required, which affects the leveling effect and the overall construction efficiency.

[0004] Therefore, there is a need for a ramming device for land leveling projects to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a ramming device for land leveling projects to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ramming device for land leveling projects, comprising a shell, a ramming block slidably connected to the bottom side wall of the shell, a rack plate fixed to the side of the ramming block, a drive motor fixed to the bottom inner side wall of the shell, a drive gear meshing with the rack plate fixed to the output end of the drive motor, a bottom cylinder fixed to the bottom of the ramming block, a ramming plate connected to the bottom of the bottom cylinder, a pressure regulating component for adjusting the position of the ramming plate provided between the bottom cylinder and the ramming plate, and multiple symmetrically distributed support legs fixed to the bottom outer side wall of the shell, with casters installed at the bottom of the support legs.

[0007] It should be noted in the solution that the pressure regulating component includes a connecting rod inserted inside the bottom cylinder, a second piston plate that fits tightly against the inner side wall of the bottom cylinder is fixed at the top of the connecting rod, the rammed earth plate is fixed at the bottom end of the connecting rod, an outer cylinder that communicates with the inside of the bottom cylinder is fixed on the side wall of the bottom cylinder, a threaded rod is inserted inside the outer cylinder, and a first piston plate that fits tightly against the inner side wall of the outer cylinder is fixed at one end of the threaded rod inside the outer cylinder.

[0008] It is worth noting that an end plate is fixed to one end of the threaded rod located outside the outer cylinder, and a handle is fixed to the side of the end plate.

[0009] Furthermore, it should be noted that a counterweight is fixed on the inner side wall of the bottom end of the outer shell, and there are two counterweights, which are symmetrically distributed on both sides of the rammed earth block.

[0010] In a preferred embodiment, a diagonal bar is fixed to one end of the housing. There are two diagonal bars, which are symmetrically distributed. A push handle is fixed to the top of both diagonal bars.

[0011] In a preferred embodiment, a rubber sleeve is fitted onto the side of the handle rod, and an opening is provided on one side of the outer shell, with a cover plate hinged to the opening end.

[0012] Compared with the prior art, the ramming device for land leveling engineering provided by this utility model has at least the following beneficial effects:

[0013] The output of the drive motor drives the drive gear to rotate in both directions, which in turn drives the rammed earth block to move up and down through the meshing of the drive gear and the rack plate. The rammed earth block then drives the rammed earth plate to perform the ramming operation. When ramming soil with different degrees of looseness, the retractability of the rammed earth plate can be adjusted by the pressure regulating component, thereby adjusting the ramming force. This allows the operator to adjust the ramming force according to the looseness of the soil, expanding the application range and improving the practicality and convenience of the ramming device.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Please see Figure 1-5 This utility model provides a ramming device for land leveling projects, including a shell 3. A ramming block 10 is slidably connected to the bottom side wall of the shell 3. A rack plate 12 is fixed to the side of the ramming block 10. A drive motor 14 is fixed to the bottom inner side wall of the shell 3. A drive gear 13 that meshes with the rack plate 12 is fixed to the output end of the drive motor 14. A bottom cylinder 9 is fixed to the bottom of the ramming block 10. A ramming plate 8 is connected to the bottom of the bottom cylinder 9. A pressure regulating component 1 for adjusting the position of the ramming plate 8 is provided between the bottom cylinder 9 and the ramming plate 8. A plurality of symmetrically distributed support legs 6 are fixed to the bottom outer side wall of the shell 3. Universal wheels 7 are installed at the bottom of the support legs 6. First, the operator pushes the ramming device at a constant speed and starts the drive motor 14. The output end of the drive motor 14 drives the drive gear 13 to rotate back and forth. Through the meshing of the drive gear 13 and the rack plate 12, the ramming block 10 moves up and down. The ramming block 10 drives the ramming plate 8 to perform the ramming operation. When ramming soil with different degrees of looseness, the retractable amount of the ramming plate 8 can be adjusted by the pressure regulating component 1, thereby adjusting the ramming force. This allows the operator to adjust the ramming force according to the looseness of the soil, expanding the application range and improving the practicality and convenience of the ramming device.

[0022] Further as Figure 2 , Figure 3 and Figure 5As shown, it is worth noting that the pressure regulating assembly 1 includes a connecting rod 106 inserted inside the bottom cylinder 9. A second piston plate 105, which fits tightly against the inner wall of the bottom cylinder 9, is fixed to the top of the connecting rod 106. A rammed earth plate 8 is fixed to the bottom end of the connecting rod 106. An outer cylinder 101, communicating with the interior of the bottom cylinder 9, is fixed to the side wall of the bottom cylinder 9. A threaded rod 103 is inserted into the outer cylinder 101. A first piston plate 102, which fits tightly against the inner wall of the outer cylinder 101, is fixed to one end of the threaded rod 103 inside the outer cylinder 101. The outer cylinder 101 and the bottom cylinder 9 are filled with a... A quantitatively permeable liquid, such as water or hydraulic oil, is used to compact soil with varying degrees of looseness. By rotating the threaded rod 103, the first piston plate 102 moves within the outer cylinder 101, thereby adjusting the hydraulic pressure inside the bottom cylinder 9. This adjusts the retractability of the adjusting rod 106 within the bottom cylinder 9, which in turn adjusts the retractability of the ramming plate 8, thus regulating the ramming force. This allows operators to adjust the ramming force according to the soil's looseness, broadening its application range and improving the practicality and convenience of the ramming device.

[0023] Further as Figure 2 As shown, it is worth noting that a counterweight 11 is fixed on the inner side wall of the bottom end of the outer shell 3. There are two counterweights 11, and the two counterweights 11 are symmetrically distributed on both sides of the rammed earth block 10. In actual operation, the counterweights 11 improve the stability of the overall device and ensure the ramming effect of the rammed earth plate 8.

[0024] The working process of this solution is as follows: The operator pushes the ramming device at a constant speed and starts the drive motor 14. The output end of the drive motor 14 drives the drive gear 13 to rotate in both directions. Through the meshing of the drive gear 13 and the rack plate 12, the ramming block 10 moves up and down. The ramming block 10 drives the ramming plate 8 to perform ramming operation. When ramming soil with different degrees of looseness, the threaded rod 103 is rotated. The threaded rod 103 drives the first piston plate 102 to move inside the outer cylinder 101, thereby adjusting the hydraulic pressure inside the bottom cylinder 9. This adjusts the retractable amount of the adjusting rod 106 inside the bottom cylinder 9, that is, the retractable amount of the ramming plate 8, thereby adjusting the ramming force. This allows the operator to adjust the ramming force according to the looseness of the soil.

[0025] Further as Figure 3 As shown, it is worth noting that an end plate 104 is fixed on one end of the threaded rod 103 located outside the outer sleeve 101, and a handle rod 107 is fixed on the side of the end plate 104. In actual operation, the threaded rod 103 can be easily rotated by the handle rod 107. The handle rod 107 has a long lever arm, which makes operation easier.

[0026] Further as Figure 1 and Figure 2 As shown, it is worth noting that a diagonal rod 4 is fixed to one end of the outer casing 3. There are two diagonal rods 4, which are symmetrically distributed. The top ends of the two diagonal rods 4 are fixed with a push handle 5. In actual operation, the push handle 5 can be used to easily move the entire device, making it convenient to operate.

[0027] Further as Figure 1 As shown, it is worth noting that a rubber sleeve is fitted on the side of the handle 107, and an opening is provided on one side of the outer casing 3, with a cover plate 2 hinged to the opening end.

[0028] In summary: The output of the drive motor 14 drives the drive gear 13 to rotate in both directions, thereby driving the rammed earth block 10 to move up and down through the meshing of the drive gear 13 and the rack plate 12. The rammed earth block 10 then drives the rammed earth plate 8 to perform the ramming operation. When ramming soil with different degrees of looseness, the retractable amount of the rammed earth plate 8 can be adjusted by the pressure regulating component 1, thereby adjusting the ramming force. This allows the operator to adjust the ramming force according to the looseness of the soil, expanding the application range and improving the practicality and convenience of the ramming device.

[0029] The drive motor 14 can be purchased from the market. The drive motor 14 is equipped with a power supply. It is a mature technology in the field and has been fully disclosed. Therefore, it will not be described again in the specification.
