A second electromagnetic valve and a third electromagnetic valve are arranged inside the dust suction pipe. Through this device, when it is necessary to use the suction head to treat dust, the third electromagnetic valve can be opened, and the suction head can clean small dead corners through the dust suction hose. When it is necessary to use the dust suction hood at the lower end to treat dust, the second electromagnetic valve can be opened, and the dust suction hood can quickly clean the dust on the ground close to the ground. The brush at the lower end of the dust suction hood increases the efficiency of cleaning the dust on the ground. The two treatment methods increase the practicability of the device.

[0004] However, the above-mentioned prior art still has the following deficiencies in use: It is difficult for this prior art to treat the polishing dust when it is formed. That is to say, it mainly treats the settled polishing powder, and it is difficult to accurately treat the floating dust, so there is still a problem that a large amount of polishing powder is inhaled by the operator.

[0005] Therefore, the utility model provides a polishing dust treatment device. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a polishing dust treatment device, including a negative pressure dust suction box 1, an air inlet 11 and an air outlet 12 are arranged on the negative pressure dust suction box 1, and the structure and principle of the negative pressure dust suction box 1 can both adopt the structure in the patent documents mentioned in the background art.

[0023] In this technical solution, it further includes a positioning column 2. A flange is welded to the bottom of the positioning column 2, and the flange is installed on the ground through expansion bolts. A cantilever 3 is rotatably connected to the top of the positioning column 2. The cantilever 3 is perpendicular to the positioning column 2. A sliding seat 4 is sleeved on the cantilever 3. The sliding seat 4 slides along the length direction of the cantilever 3. A vertically distributed hanging rod 5 is sleeved on the sliding seat 4. The hanging rod 5 and the sliding seat 4 are in upper and lower damping sliding fit. Specifically in implementation, a positioning sleeve sleeved outside the hanging rod 5 can be welded on the sliding seat 4. A second rubber sleeve is sleeved inside the positioning sleeve. Under the frictional resistance of the second rubber sleeve, the hanging rod 5 can stay at any position when moving up and down. The bottom of the hanging rod 5 is rotatably connected to a gantry connecting frame 6, and the axis of their rotating shaft is in a vertical state. A dust suction hood 7 is rotatably connected inside the gantry connecting frame 6. The dust suction hood 7 is used for dust suction. The axis of rotation of the gantry connecting frame 6 and the hanging rod 5 and the axis of rotation of the gantry connecting frame 6 and the dust suction hood 7 are perpendicular. When the gantry connecting frame 6 rotates relative to the hanging rod 5, the horizontal position of the suction port of the dust suction hood 7 can be changed. When the dust suction hood 7 rotates, its suction port can swing up and down. One side of the dust suction hood 7 is fixedly connected to a transfer pipe 8, and the transfer pipe 8 is connected to the air inlet 11 through a corrugated pipe. Thus, the above settings enable the dust suction hood 7 to move in all directions, and at the same time, the suction direction of the dust suction hood 7 can be adjusted in all directions, which is convenient for accurately absorbing dust at a fixed point during polishing.

[0024] Specifically, a transfer sleeve 31 sleeved on the positioning column 2 is welded to one end of the cantilever 3. The transfer sleeve 31 is rotatably connected to the positioning column 2, and a locking bolt 311 is screwed through its outer peripheral wall. The transfer sleeve 31 and the positioning column 2 are in clearance fit. One end of the locking bolt 311 cooperates with the outer peripheral wall of the positioning column 2. When the locking bolt 311 is tightened, one end of it presses against the positioning column 2, thereby being able to fix the transfer sleeve 31. One end of the locking bolt 311 is welded with a handle rod 3111, and the handle rod 3111 is a component for manually operating the rotation of the locking bolt 311.

[0025] In this embodiment, a sliding sleeve 42 sleeved on the cantilever 3 is fixedly welded on the sliding seat 4. A support plate 41 is welded to one side of the sliding sleeve 42. One side of the support plate 41 is elastically slidably connected to a resistance increasing rod 9 whose one end presses against the cantilever 3. The function of the resistance increasing rod 9 is to increase the sliding resistance between the sliding sleeve 42 and the cantilever 3, facilitating the stable stay of the sliding seat 4 after sliding.

[0026] Specifically, a limiting sleeve 411 sleeved outside the resistance increasing rod 9 is welded to one side of the support plate 41. A limiting ring 91 is sleeved on the resistance increasing rod 9. A supporting spring 101 is sleeved on the resistance increasing rod 9 between the limiting sleeve 411 and the limiting ring 91. The supporting spring 101 applies an elastic thrust to the resistance increasing rod 9, causing the resistance increasing rod 9 to press against the cantilever 3.

[0027] Furthermore, one end of the resistance increasing rod 9 is provided with a roller 92. A row of grooves 32 evenly distributed along the length direction is formed on one side of the cantilever 3. The grooves 32 cooperate with the roller 92. The width of the grooves 32 is smaller than the diameter of the roller 92. The row of grooves 32 will form resistance to the rolling of the roller 92. This setting can not only reduce the resistance of the sliding seat 4 during movement, but also ensure the stable stay of the sliding seat 4, making the sliding operation of the sliding seat 4 more labor-saving.

[0028] In this embodiment, a connecting sleeve 61 sleeving the bottom of the suspension rod 5 is welded to the top of the gantry connecting frame 6. A first rubber sleeve 102 that is in damping rotational fit with the suspension rod 5 is nested in the connecting sleeve 61. This setting facilitates the stable stay of the gantry connecting frame 6 after rotation and is convenient and labor-saving to operate. Connecting shafts 71 rotatably connected to the open ends of the gantry connecting frame 6 are welded to both sides of the dust suction hood 7. A pressing disc 103 used in cooperation with the gantry connecting frame 6 is screwed on the connecting shafts 71. Threaded holes for screwing the pressing disc 103 are formed on the connecting shafts 71. When the pressing disc 103 is tightened, the connecting shafts 71 and the gantry connecting frame 6 will be fixed. When the pressing disc 103 is loosened, the dust suction hood 7 can rotate freely.

[0029] Working principle: When it is necessary to suck dust at the polishing position, manually hold the suspension rod 5 and pull it towards the position of the polishing powder. At this time, the cantilever 3 will adaptively rotate, and the sliding seat 4 will adaptively slide along the cantilever 3. Then twist the gantry connecting frame 6 and rotate the dust suction hood 7 at the same time to make the suction port of the dust suction hood 7 face the polishing position, and then start the negative pressure dust suction box 1. At this time, the dust generated by polishing will be directly sucked away by the dust suction hood 7.

[0030] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
