Description

Technical Field

[0001] The utility model relates to the technical field of road construction cleaning, in particular to a road surface cleaning device for road pavement construction. Background Art

[0002] With the development of social economy, more and more places are paved with roads to facilitate traffic and transportation. During road construction, large dust and impurities are easily generated. Once too much dust accumulates on the road, it is easy to have an adverse effect on the traffic on the road. Therefore, it is necessary to clean the road surface with corresponding cleaning devices.

[0003] As in the prior art, the patent with patent authorization announcement number CN217267161U discloses a portable road surface cleaning device for road construction, including a cart, a support frame and a power assembly are respectively installed on the top outer wall of the cart, a tooth plate is slidably connected to the inner wall of the support frame, the power assembly is meshed and connected to the tooth plate, a servo motor is installed at the bottom end of the tooth plate, a connecting box is connected to the output end of the servo motor, a connecting box is clamped with a clamping block inside the connecting box, a slide groove is provided on the inner wall of the connecting box, the connecting box is clamped with a connecting plate through the slide groove, a clamping rod is fixedly installed on one side wall of the connecting plate, one end of the clamping rod is clamped with the clamping block, a pushing assembly is provided on one side wall of the connecting box, one end of the pushing assembly is connected to the connecting plate through a bearing, and the pushing assembly, the slide groove, the connecting plate and the clamping rod are provided, and the pushing assembly is rotated to drive the connecting plate to move through the slide groove, so that the connecting plate drives one end of the clamping rod to disengage from the clamping block, and the clamping block is separated from the connecting box, thereby facilitating the replacement of the worn brush.

[0004] Although the road cleaning device in the above patent is convenient for replacing worn brushes, its connecting box is too close to the bristles of the brush (that is, the connecting box is too close to the ground). During the operation of the brush, the connecting box is easily contaminated with a large amount of dust. Once the screw is contaminated with a large amount of dust, it is easy for the screw to rust and become damaged. Even if it is not damaged, the threaded groove on the screw will be clogged with dust, making it difficult to rotate the screw, and thus making it difficult to remove the brush. Therefore, the road cleaning device has certain defects. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a road surface cleaning device for road pavement construction to solve the problems raised by the background technology, making the connection between the brush and the cleaning device body simpler and not easy to be difficult to disassemble due to impurities and the like.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a road surface cleaning device for road pavement construction, comprising a cleaning device body and a motor installed on the cleaning device body, the output end of the motor is fixedly connected to an output shaft, the bottom of the output shaft is fixedly connected to a plug plate, the outer part of the plug plate is sleeved with a plug block, the bottom of the plug block is fixedly connected to a brush, the middle position of the plug plate and the plug block is provided with a connecting groove, and the inside of the connecting groove is slidably connected to a connecting block.

[0007] Furthermore, the outer sleeve of the output shaft is provided with a slidably connected protective sleeve, and the height of the protective sleeve is greater than the height of the insert block.

[0008] Furthermore, both ends of the connection block are fixedly connected to symmetrically arranged clamping blocks.

[0009] Furthermore, a limiting block is slidably connected between the clamping blocks, and a surface of the limiting block away from the inserting block is an arc surface matching the inner wall of the protective sleeve.

[0010] Furthermore, the top and the bottom of the limit block are both provided with gripping arc surfaces.

[0011] Furthermore, the insert block is T-shaped, and the end of the connecting block is trapezoidal.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In this road surface cleaning device used for road pavement construction, the brush and the cleaning device body are connected and fixed by means of a plug-in plate, a plug-in block and a connecting block. When the brush needs to be disassembled, it is only necessary to pull out the connecting block and then move the brush downward. Since it is connected and fixed by plugging and unplugging, even if there is impurity blockage, it will not affect the disassembly of the brush. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] See also Figure 1-3 A road surface cleaning device for road pavement construction includes a cleaning device body 1 and a motor 2 installed on the cleaning device body 1, an output end of the motor 2 is fixedly connected to an output shaft 3, a plug plate 5 is fixedly connected to the bottom of the output shaft 3, an plug block 8 is sleeved on the outside of the plug plate 5, a brush 7 is fixedly connected to the bottom of the plug block 8, a connecting groove 6 is opened in the middle position of the plug plate 5 and the plug block 8, and a connecting block 9 is slidably connected inside the connecting groove 6.

[0020] In the road surface cleaning device for road pavement construction in the utility model, the brush 7 is connected and fixed to the cleaning device body 1 by the plug plate 5, the plug block 8 and the connecting block 9. When the brush 7 needs to be disassembled, it is only necessary to pull out the connecting block 9 and then move the brush 7 downward. Since it is connected and fixed by plugging and pulling, even if there is impurity blockage, it will not affect the disassembly of the brush 7. In addition, the structure of the cleaning device body 1 in the utility model is similar to the structure of the portable road surface cleaning device for road construction disclosed in the patent authorization announcement number CN217267161U, so it will not be elaborated in detail here.

[0021] like Figure 1 and Figure 3 As shown, the outer sleeve of the output shaft 3 is provided with a slidingly connected protective sleeve 4, and the height of the protective sleeve 4 is greater than the height of the insert block 8.

[0022] Specifically, after the brush 7 is connected to the output shaft 3 , the protective sleeve 4 is put on the outside of the plug block 8 , so as to protect the position of the plug block 8 and the connecting block 9 and reduce the probability of dust blocking the connecting block 9 .

[0023] like Figure 2 and Figure 3 As shown, both ends of the connection block 9 are fixedly connected to symmetrically arranged clamping blocks 10. When plugging and unplugging the connection block 9, the clamping blocks 10 can be used for plugging and unplugging, so that the plugging and unplugging of the connection block 9 can be made simpler and more convenient.

[0024] like Figure 2 and Figure 3 As shown, the clamping blocks 10 are slidably connected with the limiting blocks 11 , and the side of the limiting blocks 11 away from the inserting block 8 is an arc surface matching the inner wall of the protective sleeve 4 .

[0025] Specifically, after the connecting block 9 is inserted into the connecting groove 6, the limit block 11 can be inserted between the clamping blocks 10. The connecting block 9 is restricted by the limit block 11 to prevent the connecting block 9 from being separated from the connecting groove 6. At the same time, the arc surface of the limit block 11 away from the side of the plug-in block 8 matches the inner wall of the protective sleeve 4, so the protective sleeve 4 will restrict the limit block 11 to prevent the limit block 11 from being separated from between the clamping blocks 10.

[0026] like Figure 2 and Figure 3 As shown, the top and bottom of the limit block 11 are provided with a gripping arc surface. The gripping arc surface makes the limit block 11 easier to grip.

[0027] like Figure 2 and Figure 3 As shown, the insert block 8 is T-shaped, and the end of the connecting block 9 is trapezoidal. The T-shaped insert block 8 will limit the position of the limit block 11, so that the limit block 11 is in a suitable position, and the trapezoidal connecting block 9 has a better limiting effect.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
