Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] Reference Figure 1 , Figure 2 and Figure 6The utility model provides an embodiment: a construction material grinding device for road and bridge engineering, including a base 27, the top of the base 27 is fixedly connected to an electric telescopic rod 18, the output end of the electric telescopic rod 18 is fixedly connected to a push block 17, the inner side of the push block 17 is fixedly connected to a rack 16, the top of the base 27 is fixedly connected to a fixed column 13, one side of the fixed column 13 is rotatably connected to a support column 14, the outer surface of the support column 14 is fixedly connected to a gear 15, the top of the gear 15 is fixedly connected to a fixed frame 26, the inner side of the fixed frame 26 is fixedly connected to There is a second motor 22, the output end of the second motor 22 is fixedly connected to a driving disk 23, the outer side of the driving disk 23 is rotatably connected to two push rods 24, the other end of the push rod 24 is rotatably connected to a directional moving block 25, the top of the directional moving block 25 is fixedly connected to a directional sliding block 11, the outer surface of the fixed frame 26 is provided with two sliding grooves 21, the outer surface of the fixed frame 26 is slidably connected to two clamping plates 12, the top of the base 27 is fixedly connected to a supporting frame 28, the bottom of the supporting frame 28 is installed with a grinding assembly, and the outside of the base 27 is fixedly connected to a dust collection assembly.
[0029] Specifically, the electric telescopic rod 18 is started to drive the push block 17 to move, and the gear 15 is driven to rotate, so that the fixed frame 26 is deflected at a certain angle, so that the grinding material can be adjusted in angle, so that the grinding device can process a specific area or angle more accurately, thereby improving the grinding efficiency. The second motor 22 is started to rotate the driving disk 23, thereby driving the push rod 24 to move, and the directional moving block 25 is used to make the directional slider 11 move in the slide groove 21 on the outer surface of the fixed frame 26, thereby driving the two clamping plates 12 to approach each other, thereby fixing the grinding material, saving time and human resources. The role of the slide groove 21 is to provide a moving space for the directional slider 11, and the fixed column 13 and the support column 14 play a role in assisting the gear 15 to deflect more stably.
[0030] Reference Figure 2 and Figure 3 The dust collection assembly includes a collection box 19, which is fixedly installed on the outside of the base 27. The top of the collection box 19 is fixedly connected to the collection pipe 6, and the outside of the collection box 19 is fixedly connected to the exhaust fan 20.
[0031] Specifically, by starting the exhaust fan 20, the dust generated when the material is polished is collected into the collection box 19 through the collection pipe 6, so that the dust generated when the worker polishes the material is collected into the collection box 19, thereby reducing the harm caused by the dust to the body.
[0032] Reference Figure 1 , Figure 2 and Figure 5The grinding assembly includes a first motor 1, which is fixedly installed on the top of the supporting frame 28. The output end of the first motor 1 is fixedly connected to a threaded rod 3, the outer surface of the threaded rod 3 is threadedly connected to a threaded slider 2, the outside of the threaded slider 2 is fixedly connected to a moving slider 4, a hydraulic cylinder 5 is installed on the top of the moving slider 4, the output end of the hydraulic cylinder 5 is fixedly connected to a fixed block 9, and a grinding disc 10 is installed inside the fixed block 9.
[0033] Specifically, the first motor 1 is started to rotate the threaded rod 3, so that the threaded slider 2 moves on the outer surface of the threaded rod 3, and the moving slider 4 is driven to move synchronously, and then the limit slider 7 is driven to move synchronously on the outer surface of the slide rod 8, so as to adjust the position of the grinding sheet 10, so that the movement of the grinding sheet 10 is more stable. The function of the hydraulic cylinder 5 is to adjust the lifting and lowering of the grinding sheet 10.

[0035] Specifically, the function of the slide rod 8 is to further drive the limit slide 7 to move along the outer surface of the slide rod 8 when the threaded slide block 2 drives the movable slide block 4 to move, thereby ensuring the stability of the movable slide block 4 during the movement.
[0036] Reference Figure 2 and Figure 6 The rack 16 is slidably connected to the top of the base 27 , and the rack 16 is meshedly connected with the outer side of the gear 15 .
[0037] Specifically, the rack 16 moves on the top of the base 27 to rotate the gear 15, thereby driving the fixing frame 26 to rotate, so that the angle of the grinding material is adjusted.
[0038] Reference Figure 2 , Figure 4 and Figure 6 The directional slider 11 is fixedly connected to the bottom of the clamping plate 12 , and the outer surface of the directional slider 11 is slidably connected to the inner wall of the slide groove 21 .
[0039] Specifically, the directional slider 11 moves on the inner wall of the slide groove 21, and synchronously drives the clamping plate 12 to move on the fixing frame 26. Thus, the clamping plate 12 can move in a prescribed direction, so as to better fix the grinding material.
[0040] Reference Figure 2 and Figure 3 A filter screen is fixedly connected to the interior of the collecting box 19.
[0041] Specifically, the dust is collected into the collection box 19 through the collection pipe 6, and then the dust is processed through the filter screen inside the collection box 19, so that the dust generated by the workers when grinding the materials is filtered and processed, preventing the dust from entering the exhaust fan 20 and causing damage to the exhaust fan 20.
[0042] Reference Figure 2 and Figure 6 The two clamping plates 12 are symmetrically arranged along the vertical plane of the fixing frame 26 , and a rubber pad is arranged on the inner side of the fixing frame 26 .
[0043] Specifically, the two clamping plates 12 are symmetrically arranged so that they can move synchronously, and the rubber pad inside the fixing frame 26 increases the friction of the directional slider 11, so that the clamping plates 12 can enhance the fixation of the material.
[0044] Working principle: When using the device, firstly, the building material to be polished is placed on the top of the fixed frame 26, and the second motor 22 is started to drive the driving disk 23 to rotate, so that one end of the push rod 24 swings, and under the traction of the push rod 24, the directional moving blocks 25 on both sides move along the inner wall of the fixed frame 26, and then the directional sliders 11 on both sides move in the slide groove 21, so that the two clamping plates 12 are close to each other to fix the polishing materials of different sizes;
[0045] The first motor 1 is started to rotate the threaded rod 3, so that the threaded slider 2 moves on the outer surface of the threaded rod 3, and the movable slider 4 is driven to move synchronously, and then the limit slider 7 is driven to move synchronously on the outer surface of the slide rod 8, and the position of the grinding sheet 10 is adjusted. The grinding motor is started to drive the grinding sheet 10 to rotate, and the hydraulic cylinder 5 is started, so that the grinding sheet 10 contacts the outer surface of the building material to grind it;
[0046] When the angle of the grinding material needs to be adjusted, the electric telescopic rod 18 is started to move the push block 17, thereby pushing the rack 16 to move on the top of the base 27. Under the action of the fixed column 13 and the support column 14, the gear 15 rotates, so that the fixed frame 26 is deflected at a certain angle, so that the angle of the grinding material can be adjusted.
[0047] When grinding materials, dust needs to be processed. By starting the exhaust fan 20, the collection box 19 is evacuated and compressed, so that the dust generated by the grinding materials is collected into the collection box 19 for processing under the action of the collection pipe 6, thereby reducing the workers' inhalation of dust when grinding materials, thereby reducing the physical harm to the construction workers.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
