[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the schematic embodiments of the present invention and their description are used to explain the present invention, but are not intended to limit the present invention.

[0021] Embodiment 1 of the present utility model

[0022] Reference Figure 1 and Figure 2 A concrete breaking and dust prevention device includes a hydraulic pick body 1 and a hammer head 11. The hammer head 11 is installed at the bottom of the hydraulic pick body 1. A dust cover 2 is provided below the hydraulic pick body 1. The dust cover 2 is a cylindrical paint bucket. One end of the dust cover 2 is open, and the open end of the dust cover 2 is downward. A circular hole 21 is opened at the other end of the dust cover 2. The circular hole 21 is slightly larger than the diameter of the hammer head 11, and the hammer head 11 passes through the circular hole 21.

[0023] Connecting assemblies 3 are provided between the bottom of the hydraulic pick body 1 and the dust cover 2. Two connecting assemblies 3 are located on either side of the hammer head 11. These connecting assemblies 3 include an upper connecting ring 31, an elastic connecting rope 32, and a lower connecting ring 33. The upper connecting ring 31 is fixed to the bottom of the hydraulic pick body 1, and the lower connecting ring 33 is fixed to the dust cover 2. One end of the elastic connecting rope 32 is tied to the upper connecting ring 31, and the other end is tied to the lower connecting ring 33.

[0024] Because the dust cover 2 is connected to the bottom of the hydraulic pick body 1 via an elastic connecting rope 32, the dust cover 2 will swing up and down when the hydraulic pick body 1 is not in use and is moved. To prevent the dust cover 2 from swinging up and down when the hydraulic pick body 1 is not in use, a fixing assembly 4 is provided at the bottom of the hydraulic pick body 1. The fixing assembly 4 is capable of fixing the hydraulic pick body 1 and the dust cover 2. The fixing assembly 4 includes a fixing bolt 41 and a fixing nut 42. The upper connecting ring 31 and the lower connecting ring 33 are arranged in an offset manner. The fixing bolt 41 passes through the upper connecting ring 31 and the lower connecting ring 33 and is threadedly connected to the fixing nut 42, thereby fixing the hydraulic pick body 1 and the dust cover 2. Before using the hydraulic pick body 1, remove the locking bolt 5 and the locking nut to allow the dust cover 2 to sag due to gravity.

[0025] The implementation principle of a concrete breaking and dust prevention device in Example 1 of the present invention is as follows: when breaking the concrete floor, the dust cover 2 droops due to gravity and contacts the foundation surface or floor vertically downward, and the hammer head 11 operates in the enclosed space inside the dust cover 2, which can effectively suppress dust.

[0026] Embodiment 2 of the present utility model

[0027] Reference Figure 3 and Figure 4, which differs from Example 1 in that the connecting assembly 3 includes an upper mounting block 34, a connecting spring 35, and a lower mounting block 36. The upper mounting block 34 is fixed to the bottom of the hydraulic pick body 1, and the lower mounting block 36 is fixed to the dust cover 2. Connecting blocks 351 are fixed to both ends of the connecting spring 35. Mounting slots 341 are defined on both the upper mounting block 34 and the lower mounting block 36. One connecting block 351 is inserted into the mounting slot 341 of the upper mounting block 34, and the other connecting block 351 is inserted into the mounting slot 341 of the lower mounting block 36. Connecting slots 342 are defined on the sides of the upper mounting block 34 and the lower mounting block 36 that are adjacent to each other. The connecting slot 342 is connected to the mounting slot 341, and the connecting spring 35 passes through the connecting slot 342.

[0028] Locking bolts 5 are provided on both the upper mounting block 34 and the lower mounting block 36. One connecting block 351 is fixed to the upper mounting block 34 by the locking bolts 5, and the other connecting block 351 is fixed to the lower mounting block 36 by the locking bolts 5. A dust suction pipe 6 is fixed to the top of the dust cover 2, and the end of the dust suction pipe 6 away from the dust cover is connected to a dust collector.

[0029] The implementation principle of a concrete breaking and dust prevention device in Example 2 of the present utility model is as follows: when breaking the concrete floor, the hydraulic pickaxe body 1 exerts downward force, and under the action of the connecting spring 35, the dust cover 2 abuts against the concrete floor, making the dust cover 2 more stable, and the dust suction pipe 6 can suck the smoke and dust generated when breaking the concrete into the dust collector, reducing environmental pollution.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
