[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a trench excavation equipment for municipal road construction includes a drill rod 1 and a protective cover 2. The protective cover 2 is made of rubber. The rubber has good ductility and elasticity and can withstand multiple bending. The outer surface of the drill rod 1 is detachably connected with a clamp 3. A fixing piece 13 is installed at the end of the clamp 3, and the clamp 3 is contracted by the fixing piece 13. The contraction of the fixing piece 13 can make the gap of the clamp 3 tighter, thereby increasing the stability of the connection between the overall equipment and the drill rod 1. When the drill rod 1 does not need to be protected, the gap between the clamps 3 is enlarged by loosening the fixing piece 13, and the clamp 3 is removed from the drill rod 1. A top plate 4 is connected to one side of the clamp 3, and the top plate 4 can play a top support role for the anti-slip cover. , a plurality of guide rods 5 are slidably connected to the inner side of the top plate 4, and a bottom ring 6 is connected to the bottom end of the guide rod 5. A spring 7 is sleeved on the outside of the guide rod 5, and one end of the spring 7 is connected to the lower surface of the top plate 4, and the other end of the spring 7 is connected to the upper surface of the bottom ring 6. When the drill rod 1 hammers the road surface and moves downward, the protective cover 2 is compressed and contracted, and at the same time, the bottom ring 6 compresses the spring 7. When the drill rod 1 moves upward, the elastic force of the spring 7 pushes the anti-slip cover to expand and reset. The guide rod 5 can guide the upward moving direction of the bottom ring 6 and limit the moving position of the bottom ring 6. One end of the protective cover 2 is connected to the outer surface of the top plate 4, and the other end of the protective cover 2 is connected to the outer surface of the bottom ring 6. The bottom ring 6 can provide bottom support for the protective cover 2.

[0024] One end of the plurality of guide rods 5 located above the top plate 4 is threadedly connected with a positioning nut 8, one side of the positioning nut 8 contacts the upper surface of the top plate 4, and the sliding position of the guide rod 5 is limited by the positioning nut 8 to be adjusted to the length of the anti-slip cover.

[0025] The top plate 4 and the bottom ring 6 are in the shape of a horseshoe, and the protruding parts of the top plate 4 and the bottom ring 6 are not covered by the protective cover 2. An observation port is formed at the position where the top plate 4 and the bottom ring 6 do not cover the protective cover 2. The excavator driver can observe the internal conditions of the protective cover 2 through the observation port, which is convenient for the excavator driver to judge the position where the drill rod 1 hits the road surface and the crushing condition.

[0026] The upper surface of the bottom ring 6 is connected with a plurality of guard plates 9, and the plurality of guard plates 9 are all located outside the spring 7. The outer surface of the guard plate 9 is in sliding contact with the inner wall of the top plate 4. The guard plate 9 can prevent the splashed gravel from being stuck in the spring 7 after being crushed, so that the spring 7 cannot be elastically contracted. The guard plate 9 can increase the stability of the spring 7 during operation. The inner wall of the bottom ring 6 is connected with a bracket 10, and a wire brush 11 can be supported therebetween to increase the stability of the wire brush 11. The inner wall of the bracket 10 is connected with a wire brush 11, and the wire brush 11 has a round appearance. The wire brush 11 The bottom ring 6 is in sliding contact with the outer surface of the drill rod 1. The lower surface of the bottom ring 6 is connected with a gasket 12, and the gasket 12 is made of rubber. The gasket 12 can prevent the bottom ring 6 from directly contacting the road surface and causing wear to the bottom ring 6. When the drill rod 1 repeatedly hammers the road surface, the tip and the outside of the drill rod 1 may adhere to mud. During repeated operations, more mud may adhere to the drill rod 1. Excessive adhesion of mud may cause the drill rod 1 to stall, affecting the efficiency of the drill rod 1 in breaking the road surface. The mud on the drill rod 1 can be removed by a wire brush 11 to prevent the mud from adhering to the drill rod 1.

[0027] It should be noted that in actual use, the device first puts the clamp 3 on the drill rod 1, and then tightens the fixing piece 13 to shrink the gap in the clamp 3, so that the clamp 3 is in tight contact with the drill rod 1. When the drill rod 1 is in contact with the road surface, the gasket 12 is also in contact with the road surface. When the drill rod 1 hammers the road surface, the flying gravel is blocked inside by the protective cover 2. When the drill rod 1 repeatedly retracts and stretches to hammer the road surface, the top plate 4 is driven to compress the protective cover 2. The spring 7 repeatedly pushes the top plate 4 to drive the protective cover 2 to expand, so that the gasket 12 always keeps in contact with the road surface.
