[0028] The positioning structure 4 comprises a lower embedded box 401, the inside of the lower embedded box 401 is rotationally connected with a rotating shaft 402 through an internal motor, the surface of the rotating shaft 402 is sleeved with a follow-up ring 404, the outer side of the follow-up ring 404 is slidingly connected with a follow-up plate 403.

[0029] The inner wall of the lower embedded box 401 is fixedly installed with a guide inclined plate 405 and slidingly connected with a lifting plate 406, the bottom end of the lifting plate 406 is internally provided with a ground contact plate 407, the ground contact plate 407 extends to the lower side of the lower embedded box 401, the top end of the lifting plate 406 is fixedly connected with a linkage inclined plate 408, and the top end and the bottom end of the follow-up plate 403 are respectively overlapped with the guide inclined plate 405 and the linkage inclined plate 408.

[0030] By setting the positioning structure 4, the rotating shaft 402 in the driving box 301 can promote the relative displacement of the follow-up plate 403 between the guide inclined plate 405 and the linkage inclined plate 408 through the follow-up ring 404, the follow-up plate 403 can drive the ground contact plate 407 to gradually contact the ground through the lifting plate 406, the ground contact plate 407 can position the mobile station 1, and the mobile station 1 is limited through the friction between the ground contact plate 407 and the ground, the stability of the device as a whole is increased, and the entire positioning process is mechanically operated, thereby avoiding manual installation, and the use efficiency of the device is significantly improved.

[0031] Specifically, the surface of the rotating shaft 402 is provided with a curve groove connected at the head and tail, the inner side of the follow-up ring 404 is fixedly installed with a plug rod, and the plug rod is located in the inside of the curve groove.

[0032] In this embodiment, the plug rod slides in the inside of the curve groove, promotes the relative position change of the follow-up ring 404 and the rotating shaft 402, can drive the follow-up ring 404 to move horizontally, and promotes the follow-up ring 404 to drive the follow-up plate 403 to move horizontally synchronously.

[0033] Specifically, the inner side of the follow-up plate 403 is provided with a sliding groove, and the back side of the follow-up ring 404 is slidingly connected with the inside of the sliding groove.

[0034] In this embodiment, the follow-up ring 404 slides in the sliding groove in the inner side of the follow-up plate 403, so that the follow-up ring 404 can stably and smoothly drive the follow-up plate 403 to move horizontally, and there is also a vertical relative position change between the follow-up ring 404 and the follow-up plate 403, so that the follow-up plate 403 can relatively displace between the guide inclined plate 405 and the linkage inclined plate 408.

[0035] Specifically, the top end of the follow-up plate 403 is rotationally connected with a contact wheel, and the top end of the contact wheel is overlapped with the bottom end of the guide inclined plate 405.

[0036] The setting of the abutting wheel reduces the frictional resistance between the follower plate 403 and the guide inclined plate 405 in the embodiment, so that the sliding of the follower plate 403 on the guide inclined plate 405 is smoother, and the abutting wheel can also guide the movement track of the follower plate 403, ensuring that the follower plate 403 can move along the predetermined path.

[0037] Specifically, the bottom end of the follower plate 403 is fixedly installed with an embedded rod 409, the inside of the linkage inclined plate 408 is provided with an inclined groove, and the embedded rod 409 is in sliding connection with the inside of the inclined groove.

[0038] In the embodiment, the embedded rod 409 slides in the inclined groove in the linkage inclined plate 408, which not only supports and guides the follower plate 403, but also promotes the linkage inclined plate 408 to drive the lifting plate 406 to move vertically when the follower plate 403 moves horizontally, so as to realize the contact and separation of the ground plate 407 with the ground. This design makes the operation of the positioning structure 4 more flexible and accurate, and can adapt to the needs of different terrains and working environments.

[0039] Specifically, the end of the rotating shaft 402 away from the built-in motor is fixedly sleeved with a locking gear ring 411, the inner wall of the lower embedded box 401 is movably connected with a locking gear rack 410 through a hydraulic cylinder, and the locking gear rack 410 is located behind the locking gear ring 411.

[0040] In the embodiment, when it is necessary to lock the rotating shaft 402, the output shaft of the hydraulic cylinder drives the locking gear rack 410 to move forward until the locking gear rack 410 is engaged with the locking gear ring 411. At this time, the locking gear rack 410 locks the locking gear ring 411, thereby locking the rotating shaft 402, so that the rotating shaft 402 cannot rotate. At this time, the follower ring 404, the follower plate 403, the lifting plate 406 and the ground plate 407 are in a fixed state, thereby improving the stability of the ground plate 407 after height adjustment.

[0041] In use, when it is necessary to fix the device, the built-in motor can be started by control, and the output shaft of the built-in motor drives the rotating shaft 402 to rotate. When the rotating shaft 402 rotates, the curved groove on the surface thereof rotates. Since the inserting rod inside the follower ring 404 is located inside the curved groove, and the back side of the follower ring 404 is in sliding connection with the sliding groove inside the follower plate 403, the rotation of the rotating shaft 402 can drive the follower ring 404 to move horizontally.

[0042] When the top end of the follow-up plate 403 is in contact with the bottom end of the guide inclined plate 405 during movement, the follow-up plate 403 gradually descends while moving horizontally, so that the follow-up plate 403 drives the lifting plate 406 to move vertically through the linkage inclined plate 408, and the lifting plate 406 drives the ground plate 407 at the bottom end thereof to gradually contact the ground, and the friction between the ground plate 407 and the ground limits the movement of the mobile platform 1;

[0043] When dust reduction is needed in the construction environment, the extraction pump 203 can be controlled to start, the extraction pump 203 extracts water in the water tank 202 through the delivery valve 204, and delivers the water to the water inlet end of the fog cannon machine 304 through the flexible hose. At this time, the electric hydraulic push rod 302 can be controlled to start, and the movable end of the electric hydraulic push rod 302 drives the lifting platform 303 to move vertically, and the lifting platform 303 drives the fog cannon machine 304 at the top end thereof to adjust the height, until the fog cannon machine 304 is adjusted to the appropriate spraying height.

[0044] Subsequently, the fog cannon machine 304 is controlled to start, and the fog cannon machine 304 sprays water mist into the construction environment, the water mist combines with dust particles in the air, increases the weight of the dust particles, and makes them quickly settle, thereby achieving the effect of dust reduction.

[0045] In summary, the deep hole blasting dust reduction device, by setting the positioning structure 4, the shaft 402 in the driving box 301 can drive the follow-up ring 404 to make the follow-up plate 403 relatively displace between the guide inclined plate 405 and the linkage inclined plate 408, so that the follow-up plate 403 drives the ground plate 407 to gradually contact the ground through the lifting plate 406, so that the ground plate 407 can position the mobile platform 1, and the friction between the ground plate 407 and the ground limits the movement of the mobile platform 1, which increases the stability of the device as a whole, and the entire positioning process is mechanized, thereby avoiding manual installation, which significantly improves the efficiency of the device.

[0046] It should be noted that the specific model specifications of the extraction pump 203, the delivery valve 204, the electric hydraulic push rod 302, the fog cannon machine 304, the built-in motor and the hydraulic cylinder in the deep hole blasting dust reduction device need to be determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the art, so it will not be described in detail.

[0047] And the power supply and principle of the extraction pump 203, the delivery valve 204, the electric hydraulic push rod 302, the fog cannon machine 304, the built-in motor and the hydraulic cylinder in the deep hole blasting dust reduction device are clear to those skilled in the art, and will not be described in detail here.
