[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0025] Please refer to the following: Figures 1 to 5 As shown, the construction backfill soil treatment device provided in the embodiments of this application will be described below. The construction backfill soil treatment device of this utility model includes a moving component 1, a crushing component 2, and a loosening component 3. The moving component 1 includes a vehicle body 11 and a bracket 12. Both ends of the bracket 12 are rotatably connected to the vehicle body 11 and the crushing component 2, respectively, so that the moving component 1 drives the crushing component 2 to crush the compacted soil. Figure 1As shown, in this embodiment, the bracket 12 includes two spaced-apart connecting rods 121. The two ends of the connecting rods 121 are rotatably connected to the crushing assembly 2 and the vehicle body 11, respectively, so as to drag the crushing assembly 2 along with the vehicle body 11 during movement. Preferably, a second telescopic cylinder 122 is rotatably mounted on the vehicle body 11 above the two connecting rods 121, and a connecting frame 123 is fixed above the crushing assembly 2. The output end of the second telescopic cylinder 122 is rotatably connected to the top end of the connecting frame 123. When the second telescopic cylinder 122 extends or retracts, it pulls the connecting frame 123. At this time, the end of the connecting rod 121 near the vehicle body 11 will rotate clockwise or counterclockwise, thereby adjusting the overall height of the crushing assembly 2 to better adapt to terrain undulations or different crushing depths.

[0026] In this embodiment, please refer to Figure 1 and Figure 2 As shown, the crushing assembly 2 includes a cover 21, a mixing section 22, and a first power unit 23. Specifically, the cover 21 includes a top plate 211 and two side plates 212. The mixing section 22 is rotatably disposed inside the cover 21, with its lower part protruding from the bottom of the cover 21, for crushing compacted backfill soil into small soil particles. Preferably, a cover plate 213 is hinged to the side of the cover 21 away from the vehicle body 11 to prevent soil clods from splashing during the crushing process of the mixing section 22, thus avoiding impact on the working environment and improving operational safety.

[0027] The mixing unit 22 includes a shaft 221 and multiple mixing blades 222. The two ends of the shaft 221 are rotatably connected to two side plates 212, respectively. The multiple mixing blades 222 are evenly arranged along the axial and circumferential directions of the shaft 221. A first power unit 23 drives the mixing unit 22 to rotate. In practice, the shaft 221 rotates under the drive of the first power unit 23, which in turn drives the evenly distributed mixing blades 222 to rotate synchronously. The multiple mixing blades 222 fully contact, impact, and cut the soil clods entering the enclosure 21, breaking large soil particles into smaller soil particles. This facilitates subsequent screening of the backfill soil by a soil screening machine, improving the utilization rate of the screened backfill soil.

[0028] Please see Figures 3 to 5 As shown, in this embodiment, both ends of the shaft 221 pass through the corresponding side plates 212 and are respectively fixedly provided with first sprockets 231. The first power unit 23 includes two drive shafts 232 rotatably mounted on the cover 21. The ends of the two drive shafts 232 that are far apart from each other pass through the corresponding side plates 212 and are respectively fixedly provided with second sprockets 233. A chain 234 is wound around the outer side of each first sprocket 231 and second sprocket 233. The top surface of the cover 21 is provided with a drive assembly 235 for driving the two drive shafts 232 to rotate. Preferably, a protective cover 236 is fixedly provided on the outer side of each side plate 212 to protect the first sprocket 231, the second sprocket 233 and the chain 234.

[0029] For details, please refer to Figure 4 As shown, the drive assembly 235 includes a connecting cylinder 2351 and a drive shaft 2352. The connecting cylinder 2351 has a hollow internal structure, and its central axis is collinear with the two drive shafts 232. The ends of the two drive shafts 232, which are close to each other, are rotatably inserted into the connecting cylinder 2351 and are respectively fixed with first helical gears 2353. One end of the drive shaft 2352 is rotatably inserted into the connecting cylinder 2351 and is fixed with a second helical gear 2354. The second helical gear 2354 meshes with the two first helical gears 2353. In practice, an external power device, such as a drive motor (not shown in the figure) in the prior art, can drive the drive shaft 2352 to rotate, thereby driving the second helical gear 2354 and the two first helical gears 2353 meshing with the second helical gear 2354 to rotate, so that the two drive shafts 232 rotate synchronously. Then, the second sprocket 233 drives the first sprocket 231 to rotate through the chain 234, causing the shaft 221 and the stirring blade 222 to rotate.

[0030] like Figure 1 As shown, preferably, the vehicle body 11 is a tractor. The end of the drive shaft 2352 away from the connecting cylinder 2351 is connected to the power shaft (not shown in the figure) of the tractor head via a universal joint drive shaft 2355, which is a conventional technology. In implementation, the tractor power shaft transmits power to the drive shaft 2352 via the universal joint drive shaft 2355. The second helical gear 2354 simultaneously drives the two first helical gears 2353 to rotate, causing the drive shafts 232 on both sides to rotate synchronously. It should be noted that the tractor head in the prior art is equipped with a power shaft, and the power shaft is a conventional technology, which will not be described in detail here. By setting the vehicle body 11 as a tractor, the tractor is used as the power source, eliminating the need for an additional high-power motor, thereby reducing equipment costs.

[0031] Please see Figure 2 Combination Figure 4 As shown, the loosening component 3 is fixed to the side of the cover 21 near the vehicle body 11 to pre-loosen the highly consolidated backfill soil, making it easier for the crushing component 2 to better crush large clumps of soil. In this embodiment, the loosening component 3 includes a plow assembly 31 and a lifting component 32 for controlling the raising and lowering of the plow assembly 31. That is, the lifting component 32 is used to adjust the relative position (depth of insertion into the ground) of the plow assembly 31 to adapt to different working environments.

[0032] Specifically, the lifting assembly 32 is positioned above the plow blade assembly 31 and includes a fixed plate 321 and a first telescopic cylinder 322. One side of the fixed plate 321 is fixedly connected to the cover 21, and the output end of the first telescopic cylinder 322 passes through the fixed plate 321 and is fixedly connected to the top of the plow blade assembly 31. In this embodiment, there are two first telescopic cylinders 322, located at opposite ends of the fixed plate 321, to stably drive the plow blade assembly 31 to rise and fall. Preferably, two sliding rods 323 are vertically fixed to the top surface of the plow blade assembly 31, with the top ends of both sliding rods 323 passing through the fixed plate 321 and slidably connected to it. This further improves the stability of the plow blade assembly 31 during the lifting and lowering process.

[0033] In this embodiment, the plow blade assembly 31 includes a connecting plate 311 and a plurality of plow blades 312. The plurality of plow blades 312 are evenly arranged along the length direction of the connecting plate 311, and the output end of the first telescopic cylinder 322 is fixedly connected to the connecting plate 311. In practice, the first telescopic cylinder 322 drives the connecting plate 311 to rise and fall, thereby causing the evenly distributed plow blades 312 to simultaneously insert into or detach from the soil to loosen the compacted soil clods.

[0034] Please see Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, each side plate 212 has a depth limiting plate 24 at its bottom. The depth limiting plate 24 protects the crushing component 2 while allowing adjustment of the crushing depth, preventing energy waste due to over-crushing. Preferably, each depth limiting plate 24 is arc-shaped, with one end rotatably connected to one side of the side plate 212. Specifically, one end of the depth limiting plate 24 is rotatably connected to the side plate 212 via bolts 25, and the other side of the side plate 212 has an adjustment component 26 for adjusting the rotation of the depth limiting plate 24. By setting the depth limiting plate 24 to an arc shape, friction between the depth limiting plate 24 and the soil is reduced, and the adjustment component 26 allows for flexible setting of the crushing depth.

[0035] In this embodiment, the adjustment component 26 includes a first connecting block 261, a fixing block 262, and a screw 263. The first connecting block 261 is rotatably mounted at the other end of the depth-limiting plate 24 (away from the end rotatably connected to the side plate 212). The fixing block 262 is fixed to the side plate 212 and located above the first connecting block 261. One end of the screw 263 is rotatably connected to the first connecting block 261, and the other end of the screw 263 extends through the fixing block 262 away from it, and is screwed to the fixing block 262. In practice, rotating the screw 263 forward or backward causes it to move along the thread of the fixing block 262, thereby pushing or pulling the first connecting block 261, causing the depth-limiting plate 24 to rotate. This adjusts the angle of the depth-limiting plate 24 to adapt to the breaking requirements of different soil layers. By using the screw 263 in conjunction with the fixing block 262 and the first connecting block 261, precise adjustment of the angle of the depth-limiting plate 24 is achieved, resulting in a stable structure.

[0036] In a specific implementation of this invention, the drive shaft 2352 of the first power unit 23 is connected to the power shaft of the tractor via a universal joint transmission shaft 2355, using the tractor as the power source to move the crushing assembly 2 and the loosening assembly 3. During operation, the height of the crushing assembly 2 is adjusted by the second telescopic cylinder 122 to ensure it is in a suitable working state. At this time, the depth limiting plate 24 is adjusted to a preset angle via the screw 263, thereby limiting the working depth of the crushing assembly 2 and preventing over-crushing. Next, the first telescopic cylinder 322 of the loosening assembly 3 is activated, which drives the plow assembly 31 to rise or fall, thereby controlling the depth of the plow blade 312 inserted into the compacted soil. As the tractor moves, the loosening assembly 3 performs initial loosening of the soil. Then, the loosened soil enters the crushing assembly 2. At the same time, the tractor's power is transmitted to the drive shaft 232 through the universal joint drive shaft 2355, drive shaft 2352, second helical gear 2354, and first helical gear 2353. Then, through the first sprocket 231, chain 234, and second sprocket 233, the shaft 221 and mixing blades 222 are rotated to crush the backfill soil.

[0037] After being crushed, the backfill soil is then screened by a soil screening machine, which greatly increases the utilization rate of the backfill soil and the efficiency of the screening process. It should be noted that the backfill soil treatment device for construction of this utility model can crush the soil on a large scale and reduce the moisture content of the backfill soil to a certain extent, thus greatly improving the quality of the backfill soil.

[0038] This utility model addresses the large-scale backfill soil requirements of projects such as converter stations. By integrating the loosening component 3 and the crushing component 2, it solves the problem of low utilization rate of directly screened consolidated soil, significantly improving backfill soil utilization. Simultaneously, utilizing a tractor as the power source and mobile carrier reduces equipment costs, enhances operational flexibility, and adapts to a wide range of construction scenarios. The lifting component 32 allows adjustment of the insertion depth of multiple plow blades 312 into the ground, adapting to soils with varying degrees of consolidation. The adjusting component 26 changes the distance between the bottom of the depth-limiting plate 24 and the ground, facilitating the restriction of the crushing component 2's operating depth and improving processing efficiency and quality.

[0039] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
