Description

Technical Field

[0001] The utility model relates to the technical field of compaction devices, in particular to an earth and stone compaction device. Background Art

[0002] In current earthwork projects, self-propelled chain belt tampers are widely used for ground compaction operations. However, due to the unevenness of the ground at the construction site, there are often mud and potholes that are higher or lower than the designed compaction surface. This irregular terrain poses a challenge to the operating efficiency and compaction quality of the tamping machine.

[0003] Specifically, when the tamping machine encounters soil that is higher than the tamping surface, it is often unable to fully tamp the area in one go, which results in the tamping machine having to perform repeated tamping operations on this location, which not only reduces work efficiency but also increases energy consumption and maintenance costs. On the other hand, if the potholes on the ground are tamped directly without being treated, there will be obvious depressions in the tamped ground, making the overall tamped surface uneven. This uneven tamping surface not only affects the appearance, but may also reduce the quality of subsequent projects, such as stability when laying materials. Utility Model Content

[0004] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] To this end, the purpose of the utility model is to propose an earthwork compaction device that can push the soil in front of the tamping block that is higher than the tamping surface forward and effectively fill the potholes. By automatically pushing the soil higher than the tamping surface forward, the number of repeated tamping of the same area by the tamping machine is reduced, which not only shortens the working cycle, but also reduces the wear and energy consumption of the tamping machine, thereby improving work efficiency. Secondly, the filling function of the potholes ensures the integrity and flatness of the tamping surface. The filling of the potholes makes the compacted ground more uniform, improves the compaction quality, and provides a more stable foundation for subsequent projects. In addition, the device is simple to operate and easy to maintain, and can be seamlessly integrated with the existing self-propelled chain belt tamping machine without the need for large-scale transformation or upgrading of the existing equipment. This greatly reduces the user's use cost and threshold, making earthwork projects more efficient and economical.

[0006] To achieve the above-mentioned purpose, the utility model proposes an earthwork compaction device, comprising a self-propelled chain belt rammer, a bracket assembly, a supporting mechanism, a soil leveling assembly and a transmission mechanism, wherein the self-propelled chain belt rammer is arranged on the ground; the bracket assembly is arranged on the surface of the self-propelled chain belt rammer; the supporting mechanism is arranged on the top of the bracket assembly, and one end of the supporting mechanism is connected to the surface of the self-propelled chain belt rammer; the soil leveling assembly comprises a pressure roller plane mechanism, an initial pressure mechanism and a front shovel, wherein the pressure roller plane mechanism, the initial pressure mechanism and the front shovel are arranged on the surface of the bracket assembly in sequence; the transmission mechanism comprises a first transmission belt and a second transmission belt, wherein one end of the first transmission belt is connected to one end of the pressure roller plane mechanism, the other end of the first transmission belt is connected to one end of the transmission roller in the self-propelled chain belt rammer, one end of the second transmission belt is connected to one end of the pressure roller plane mechanism, and the other end of the second transmission belt is connected to one end of the initial pressure mechanism.

[0007] The earthwork compaction device of the utility model can push forward the soil in front of the tamping block that is higher than the compaction surface, and effectively fill the potholes. By automatically pushing forward the soil that is higher than the compaction surface, the number of repeated compaction times of the tamping machine on the same area is reduced, which not only shortens the working cycle, but also reduces the wear and energy consumption of the tamping machine, thereby improving work efficiency. Secondly, the filling function of the potholes ensures the integrity and flatness of the compacted surface. The filling of the potholes makes the compacted ground more uniform, improves the compaction quality, and provides a more stable foundation for subsequent projects. In addition, the device is simple to operate and easy to maintain, and can be seamlessly integrated with the existing self-propelled chain belt tamping machine without the need for large-scale transformation or upgrading of the existing equipment. This greatly reduces the user's use cost and threshold, making earthwork projects more efficient and economical.

[0009] Specifically, the bracket assembly includes a slide, an H-shaped sleeve and a locking bolt, wherein the slide is symmetrically rotatably connected to the surface of the self-propelled chain-belt rammer and is located on the outside of the ramming block in the self-propelled chain-belt rammer; the H-shaped sleeve is sleeved on the outside of one end of the two groups of slides away from the surface of the self-propelled chain-belt rammer, and is fixedly connected to the surface of the slide through the locking bolt.

[0028] Embodiments of the present invention are described in detail below, examples of which 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 intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0029] The earth and stone compacting device according to the embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0030] like Figure 1-Figure 3 As shown, the earth and stone compacting device of the embodiment of the utility model may include a self-propelled chain belt tamping machine 100, a bracket assembly 1, a supporting mechanism 2, a soil leveling assembly 3 and a transmission mechanism 4.

[0031] The self-propelled chain belt rammer 100 is arranged on the ground, the bracket assembly 1 is arranged on the surface of the self-propelled chain belt rammer 100, the support mechanism 2 is arranged on the top of the bracket assembly 1, and one end of the support mechanism 2 is connected to the surface of the self-propelled chain belt rammer 100;

[0032] The soil leveling assembly 3 includes a pressure roller plane mechanism 31 , an initial pressure mechanism 32 and a front shovel 33 .

[0033] The pressing roller plane mechanism 31 , the initial pressing mechanism 32 and the front shovel 33 are sequentially arranged on the surface of the bracket assembly 1 .

[0034] The transmission mechanism 4 includes a first transmission belt 41 and a second transmission belt 42 .

[0035] Among them, one end of the first transmission belt 41 is connected to one end of the pressure roller plane mechanism 31, the other end of the first transmission belt 41 is connected to one end of the transmission roller 102 in the self-propelled chain belt rammer 100, one end of the second transmission belt 42 is connected to one end of the pressure roller plane mechanism 31, and the other end of the second transmission belt 42 is connected to one end of the initial pressure mechanism 32.

[0036] It should be noted that the self-propelled chain belt rammer 100 described in this embodiment is a prior art, so it will not be described in detail here.

[0037] It should also be noted that the driving roller 102 in the self-propelled chain belt tamping machine 100 is used to drive the wheels to move and drive the tamping block 101 to perform tamping operations.

[0038] It can be understood that the use of the bracket assembly 1, the supporting mechanism 2, the soil leveling assembly 3 and the transmission mechanism 4 does not affect the normal operation of the self-propelled chain belt tamping machine 100 itself.

[0039] It can also be understood that the angle of the front shovel 33 on the bracket assembly 1 is adjustable, and the height difference between it and the tamping surface can be changed by adjusting its angle.

[0040] Specifically, the support assembly 1 is lowered to change from a vertical state to a horizontal state. After the angle is fixed, the support mechanism 2 on the support assembly 1 is connected to the surface of the self-propelled chain belt rammer 100 to make the support assembly 1 in a triangular structure to improve its structural stability.

[0041] Then, the angle of the front shovel 33 is adjusted to tilt it downward to facilitate the subsequent bulldozing operation, wherein the bottom of the front shovel 33 is higher than the tamping surface set before tamping by the tamping block 101, that is, the initial tamping surface.

[0042] After the position of the front shovel 33 is adjusted, the self-propelled chain belt rammer 100 is started normally. When the self-propelled chain belt rammer 100 moves, the front shovel 33 pushes the soil in front of the tamping block 101 that is higher than the set height of the initial tamping surface to move forward.

[0043] At the same time, the operation of the drive roller 102 of the self-propelled chain belt rammer 100 will also synchronously drive the roller plane mechanism 31 to operate through the first drive belt 41. The operation of the roller plane mechanism 31 will also drive the initial pressure mechanism 32 to operate through the second drive belt 42. The initial pressure mechanism 32 will perform preliminary compaction on the soil that is still higher than the initial compaction surface after being flattened by the front shovel 33 to prevent it from loosening and collapsing under the vibration of the tamping block 101. The operation of the roller plane mechanism 31 will level the surface of the soil after preliminary compaction, and the leveled soil surface will be consistent in height with the initial compaction surface. Finally, the tamping block 101 will compact the soil at the height of the initial compaction surface to the actual compaction surface, that is, the final compaction surface.

[0044] This device can push the soil in front of the tamping block 101 that is higher than the tamping surface forward and effectively fill the potholes. By automatically pushing the soil higher than the tamping surface forward, the number of repeated tamping of the same area by the self-propelled chain belt tamping machine 100 is reduced, which not only shortens the working cycle, but also reduces the wear and energy consumption of the self-propelled chain belt tamping machine 100, thereby improving work efficiency. Secondly, the filling function of the potholes ensures the integrity and flatness of the tamping surface. The filling of the potholes makes the compacted ground more uniform, improves the compaction quality, and provides a more stable foundation for subsequent projects. In addition, this device is simple to operate and easy to maintain, and can be seamlessly integrated with the existing self-propelled chain belt tamping machine 100 without large-scale transformation or upgrading of existing equipment. This greatly reduces the user's use cost and threshold, making earthwork projects more efficient and economical.

[0045] In one embodiment of the present invention, Figure 2 As shown, the bracket assembly 1 may include a slide frame 11 , an H-shaped sleeve frame 12 and a locking bolt 13 .

[0046] Among them, the slide 11 is symmetrically rotatably connected to the surface of the self-propelled chain belt rammer 100, and is located on the outside of the ramming block 101 in the self-propelled chain belt rammer 100. The H-shaped sleeve 12 is sleeved on the outside of one end of the two groups of slides 11 away from the surface of the self-propelled chain belt rammer 100, and is fixedly connected to the surface of the slide 11 through a locking bolt 13.

[0047] It should be noted that a sliding groove is provided on the surface of the slide 11 described in this embodiment to facilitate the sliding of one end of the flat pressing roller 311 .

[0048] It should also be noted that an angle marking line is provided at the connection between the surface of the self-propelled chain belt rammer 100 and the slide 11 to facilitate adjustment of the angle of the slide 11 .

[0049] Specifically, by loosening the locking bolt 13 , the H-shaped sleeve 12 can slide relatively on the surface of the slide 11 , thereby achieving the purpose of length adjustment. By tightening the locking bolt 13 , the H-shaped sleeve 12 can be fixed on the surface of the slide 11 .

[0050] In one embodiment of the present invention, Figure 1-Figure 2 As shown, the support mechanism 2 may include a threaded connection sleeve rod 21 and a hinge seat 22 .

[0051] Among them, a mounting groove is opened on the top of the H-shaped frame 12, and the hinge seat 22 is set on the surface of the self-propelled chain belt rammer 100. One end of the threaded connection sleeve rod 21 is hinged and fixed to the inner wall of the mounting groove, and the other end of the threaded connection sleeve rod 21 is hinged and fixed to the surface of the hinge seat 22.

[0052] It should be noted that the threaded connection sleeve 21 is composed of multiple groups of threaded tubes that are sleeved together. The outermost group of threaded tubes is hinged and fixed to the inner wall of the installation groove, and the innermost group of threaded tubes is hinged and fixed to the hinge seat 22.

[0053] It should also be noted that one end of the threaded connection sleeve rod 21 described in this embodiment (ie, a group of threaded tubes in the innermost circle) is detachably connected to the hinge seat 22 .

[0054] Specifically, before work, the bracket assembly 1 is first placed in a horizontal state. After the angle is fixed, one end of the threaded connection sleeve rod 21 is moved out from the inside of the installation groove, and then its length is adjusted, and finally connected to the hinge seat 22. At this time, the bracket assembly 1 is a triangular structure with strong stability.

[0055] Then adjust the angle of the front shovel 33 to facilitate the subsequent bulldozing operation.

[0056] When folding, disassemble the threaded connection sleeve rod 21 and the hinge seat 22, then straighten the bracket assembly 1, and fit the straightened bracket assembly 1 into the limit block 200, and fix the bracket assembly 1 with the limit bolts on the limit block 200. If you feel that the limit bolt fixation alone is not safe enough, you can reconnect one end of the threaded connection sleeve rod 21 to the hinge seat 22 so that it is in a triangular structure again, which effectively improves stability and safety.

[0057] In one embodiment of the present invention, Figure 2 As shown, the pressure roller plane mechanism 31 may include a flat pressure roller 311 , a first synchronous wheel 312 and a second synchronous wheel 313 .

[0058] Among them, the flattening roller 311 is rotatably connected to the inner wall of the H-shaped frame 12, and the two ends of the flattening roller 311 respectively pass through the outside of the H-shaped frame 12 and are fixedly connected with the first synchronous wheel 312, and the second synchronous wheel 313 is coaxially arranged on the surface of the first synchronous wheel 312. The first synchronous wheel 312 is connected to one end of the transmission roller 102 in the self-propelled chain rammer 100 through the first transmission belt 41, and the second synchronous wheel 313 is connected to one end of the initial pressure mechanism 32 through the second transmission belt 42.

[0059] It should be noted that the flattening roller 311 described in this embodiment is used to flatten the ground after the pressing block 327 has been initially compacted.

[0060] Specifically, the transmission roller 102 in the self-propelled chain rammer 100 rotates and synchronously drives the first synchronous wheel 312 to rotate through the first transmission belt 41. The rotation of the first synchronous wheel 312 synchronously drives the flattening roller 311 and the second synchronous wheel 313 to rotate. The flattening roller 311 rotates to level the ground after the pressure block 327 has been initially compacted, so as to facilitate subsequent compaction operations. The rotation of the second synchronous wheel 313 synchronously drives the driven wheel 324 to rotate through the second transmission belt 42.

[0061] In one embodiment of the present invention, Figure 3 As shown, the initial pressure mechanism 32 may include a fixed frame 321 , a transmission shaft 322 , an irregular top block 323 , a passive wheel 324 , a pressure frame 325 , a return spring 326 and a pressure block 327 .

[0062] Among them, the fixed frame 321 is set on the surface of the H-shaped sleeve 12, the transmission shaft 322 is rotatably connected to the inner wall of the fixed frame 321, the irregular top block 323 is symmetrically set on the surface of the transmission shaft 322 and is located inside the fixed frame 321, one end of the transmission shaft 322 passes through the outside of the H-shaped sleeve 12 and is fixedly connected to a passive wheel 324, and the passive wheel 324 is connected to the second synchronous wheel 313 through a second transmission belt 42, the pressure frame 325 is set at the top of the fixed frame 321, and a reset spring 326 is connected between the bottom of the pressure frame 325 and the top of the fixed frame 321, the pressure block 327 is symmetrically set at the bottom of the pressure frame 325, and is slidably connected to the inner wall of the fixed frame 321, and one end of the pressure block 327 passes through the bottom of the fixed frame 321.

[0063] It should be noted that grooves are respectively provided at the top of the fixing frame 321 described in this embodiment, corresponding to the positions of the irregular top block 323 and the return spring 326 .

[0064] Specifically, the rotation of the second synchronous wheel 313 synchronously drives the passive wheel 324 to rotate through the second transmission belt 42. The rotation of the passive wheel 324 synchronously drives the transmission shaft 322 and the irregular top block 323 to rotate. During the rotation of the irregular top block 323, one end of the irregular top block 323 intermittently protrudes from the top of the fixed frame 321 and presses against the pressure frame 325 to move upward. When the irregular top block 323 enters the groove, under the elastic force of the return spring 326, the pressure frame 325 moves downward, and its bottom is re-fitted with the top of the fixed frame 321. During the up and down movement of the pressure frame 325, the pressure block 327 at its bottom intermittently performs preliminary compaction on the soil to prevent it from loosening and collapsing under the vibration of the tamping block 101, and the use effect is good.

[0065] In one embodiment of the present invention, Figure 1As shown, a limit block 200 is provided on the surface of the self-propelled chain belt tamping machine 100 .

[0066] It should be noted that the limit block 200 is used to limit the travel of the slide 11. When the slide 11 contacts the surface of the limit block 200, the slide 11 is in a vertical state.

[0067] It should also be noted that a limiting bolt (not shown in the figure) is provided on the surface of the limiting block 200 described in this embodiment, and the limiting bolt is connected to a threaded hole (not shown in the figure) opened on the surface of the slide 11, thereby fixing the position of the slide 11.

[0068] It is understandable that, in order to prevent the limiting bolt from falling and being lost, an anti-lost rope is provided on the limiting bolt, and the other end of the anti-lost rope is connected to the limiting block 200.

[0069] It is also understandable that the fixing method may also be rope fixing.

[0070] In summary, the earthwork compaction device of the embodiment of the utility model can push the soil in front of the tamping block 101 that is higher than the compaction surface forward, and effectively fill the potholes. By automatically pushing the soil that is higher than the compaction surface forward, the number of repeated compaction times of the self-propelled chain belt tamping machine 100 on the same area is reduced, which not only shortens the working cycle, but also reduces the wear and energy consumption of the self-propelled chain belt tamping machine 100, thereby improving work efficiency. Secondly, the filling function of the potholes ensures the integrity and flatness of the compacted surface. The filling of the potholes makes the compacted ground more uniform, improves the compaction quality, and provides a more stable foundation for subsequent projects. In addition, the device is simple to operate and easy to maintain, and can be seamlessly integrated with the existing self-propelled chain belt tamping machine 100 without large-scale transformation or upgrading of the existing equipment. This greatly reduces the user's use cost and threshold, making earthwork projects more efficient and economical.
