[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0034] Refer to Figures 1-5 andFigure 7 , an embodiment provided by the present utility model: a trench-digging device for pre-burying pipelines for municipal water supply and drainage, including a vehicle frame 1. The vehicle frame 1 provides support for the installation of the hydraulic rod 14, and provides limit and guidance for the sliding of the bracket 2. A rotating shaft 12 is rotatably connected to the inner wall of the vehicle frame 1. The inner wall of the rear end of the rotating shaft 12 is fixedly connected to the output shaft of the motor 13. The rotating shaft 12 drives the main turntable 11 to rotate through the rotation of the motor 13. A main turntable 11 is fixedly connected to the outer wall of the front end of the rotating shaft 12. Excavation columns are evenly distributed on the outer wall of the main turntable 11. The main turntable 11 rotates with the rotation of the rotating shaft 12. A fixing column 9 is fixedly connected to the inner wall of the front end of the main turntable 11. The fixing column 9 provides support for the rotation of the threaded rod 8 and provides support for the sliding of the clamping plate 10. A clamping plate 10 is elastically connected to the inner wall of the fixing column 9 through a first spring 16. The clamping plate 10 moves under the action of the movement of the tapered block 15 and the elastic force of the first spring 16. When the clamping plate 10 moves out of the inner wall of the fixing column 9, it limits the secondary turntable 7. There are two clamping plates 10, and the two clamping plates 10 are symmetrically arranged. The outer wall of the clamping plate 10 slides on the inner wall of the fixing column 9. One end of the first spring 16 is fixedly connected to the inner wall of the fixing column 9, and the other end of the first spring 16 is fixedly connected to the rear outer wall of the clamping plate 10. A threaded rod 8 is threadedly connected to the inner wall of the front end of the fixing column 9. By rotating the threaded rod 8, the movement of the tapered block 15 is driven. A tapered block 15 is fixedly connected to the outer wall of the rear end of the threaded rod 8. The front diameter of the tapered block 15 is larger than the rear diameter. The tapered block 15 moves through the rotation of the threaded rod 8. A secondary turntable 7 slides on the outer wall of the fixing column 9. The secondary turntable 7 is installed on the main turntable 11 to increase the width of the trench. A clamping block 18 is elastically connected to the inner wall of the secondary turntable 7 through a second spring 17. The clamping block 18 moves forward under the action of the elastic force of the second spring 17. When the outer wall of the clamping block 18 is clamped on the inner wall of the front end of the main turntable 11, the secondary turntable 7 can be fixed on the main turntable 11. The outer wall of the clamping block 18 slides on the inner wall of the secondary turntable 7. The upper outer wall of the clamping block 18 is inclined. One end of the second spring 17 is fixedly connected to the inner wall of the secondary turntable 7, and the other end of the second spring 17 is fixedly connected to the rear outer wall of the clamping block 18. A protection component is arranged on the front outer wall of the vehicle frame 1 for protection during trench digging. An adjustment component is arranged on the upper outer wall of the vehicle frame 1 for adjusting the height of the rotating shaft 12.
[0035] Refer to Figure 1 and Figure 6, the protection component includes the first guard plate 3. When the main turntable 11 rotates, the first guard plate 3 blocks the sand, dust, etc. lifted by the main turntable 11, playing a role in protecting the surrounding personnel. The outer wall of the rear end of the first guard plate 3 is fixedly connected to the outer wall of the front end of the vehicle frame 1. The second guard plate 6 is slidably connected to the outer wall of the upper end of the first guard plate 3. After the auxiliary turntable 7 is installed, the second guard plate 6 moves forward to increase the blocking range of the lifted sand, dust, etc. The block 4 is elastically connected to the outer wall of the upper end of the second guard plate 6 through the third spring 5. The block 4 is clamped on the inner wall of the upper end of the first guard plate 3, so that the second guard plate 6 can be fixed on the first guard plate 3. One end of the third spring 5 is fixedly connected to the outer wall of the upper end of the second guard plate 6, and the other end of the third spring 5 is fixedly connected to the lower outer wall of the block 4.
[0036] Refer to Figure 1 and Figure 2 , the adjustment component includes the hydraulic rod 14. The hydraulic rod 14 is provided to drive the bracket 2 to move and adjust the height of the bracket 2. The outer wall of the hydraulic rod 14 is fixedly connected to the outer wall of the upper end of the vehicle frame 1. The outer wall of the bottom end of the hydraulic rod 14 is fixedly connected to the bracket 2. The bracket 2 provides support for the rotation of the rotating shaft 12. The bracket 2 drives the rotating shaft 12 to adjust the height through the operation of the hydraulic rod 14. The outer wall of the rear end of the bracket 2 is fixedly connected to the motor 13. The operation of the motor 13 is used to drive the rotating shaft 12 to rotate.
[0037] Working principle: The operation of the hydraulic rod 14 drives the bracket 2 to slide on the inner wall of the vehicle frame 1 to adjust the positions of the rotating shaft 12 and the main turntable 11. Then, by starting the motor 13, the operation of the motor 13 drives the rotating shaft 12 to rotate. The rotating shaft 12 drives the main turntable 11 to rotate to dig a trench through the excavation column on the outer wall. When the width of the trench is relatively wide, the auxiliary turntable 7 is slid onto the fixed column 9, and the latch 18 of the auxiliary turntable 7 is aligned with the notch on the inner wall of the front end of the main turntable 11 and moved in. Then, the auxiliary turntable 7 is rotated counterclockwise by ninety degrees. During the rotation process, the inner wall of the front end of the main turntable 11 squeezes the inclined surface of the latch 18 to make the latch 18 retract. After the auxiliary turntable 7 rotates to ninety degrees, the latch 18 pops out, so that the auxiliary turntable 7 is installed on the main turntable 11. Then, by rotating the threaded rod 8, the tapered block 15 is driven to move backward, squeezing the clamping plate 10 to move outward to limit the auxiliary turntable 7. The block 4 is moved to release the limit on the second guard plate 6, and the second guard plate 6 is moved forward and then the block 4 is released to realize the extension of the second guard plate 6 and expand the protection range.
[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
