DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0026] Reference Figures 1 to 5 A wall cleaning device for construction engineering comprises a shell 1, a cutting module and a cleaning component 6, the cleaning component 6 is assembled on the upper part of the inner cavity of the shell 1, the cutting module comprises a cutting component 2, an elastic monitoring component 3, a limiting component 4 and a collecting tank 5, a rectangular cavity is opened on the left wall of the shell 1, and a rubber sheet is fixedly installed on the outer periphery of the left wall of the shell 1, the cutting component 2 is movably assembled in the shell 1, and the cutting component 2 is located in the rectangular cavity, the inner wall of the shell 1 is equipped with one end of the elastic monitoring component 3, the limiting component 4 is assembled on the inner wall of the shell 1, and the limiting component 4 is located opposite to the cutting component 2, and the collecting tank 5 is assembled at the output end of the limiting component 4.

[0027] The cutting module is used to cut and clean the protrusions caused by the overflow of mortar joints on the wall surface, and the cleaned protrusions fall into the collection tank 5 for recovery.

[0028] The cleaning component 6 is used to clean the dust on the wall.

[0029] There are four rubber sheets, which are respectively installed at the upper side, lower side, front side and rear side of the left wall periphery of the housing 1. Each rubber sheet can be bent and deformed individually. Figure 4 As shown, a rubber sheet is installed on the outer periphery of the left wall of the housing 1.

[0030] The rubber sheet has elasticity and bending properties. When the device moves along the wall, the design of the rubber sheet will not block the protrusion, allowing the device to move smoothly. At the same time, the design of the rubber sheet can block the outside of the rectangular cavity on the left wall of the shell 1 to prevent the protrusion from falling out after being cut.

[0031] like Figure 5 As shown, the cutting assembly 2 includes a fixed shaft 21, a deflection cylinder 22 and a knife body 23. The fixed shaft 21 is fixedly mounted on the inner wall of the shell 1, and the deflection cylinder 22 is rotatably mounted on the fixed shaft 21. A torsion spring is mounted between the fixed shaft 21 and the deflection cylinder 22. The knife body 23 is mounted on the outer wall of the deflection cylinder 22. A fixed plate 25 is fixedly mounted on the outer wall of the deflection cylinder 22, and the other end of the elastic monitoring assembly 3 contacts the fixed plate 25.

[0032] A mounting block is provided on the upper end of the surface of the blade body 23, a mounting groove is provided on the outer peripheral surface of the deflection cylinder 22, and the mounting block is installed in the mounting groove. An inclined groove is provided on the upper ends of the blade body 23 and the mounting block. When the blade body 23 contacts the protrusion, the blade body 23 can be deflected by force, and at the same time, the fixing plate 25 is driven to deflect, and the elastic monitoring component 3 detects the pressure generated by the deflection. When the blade body 23 passes through the protrusion, it will reset, and then the protrusion can be cut.

[0033] Specifically, if Figure 5 As shown, a stripping blade body 24 is fixedly mounted on the surface of the blade body 23 .

[0034] When the blade 23 is used to cut a relatively large protrusion, as the cutting proceeds, the stripping blade 24 will contact the protrusion to strip the protrusion.

[0035] Specifically, the front and rear surfaces of the inner cavity of the shell 1 are equipped with slide rails, and moving blocks are fixedly installed at both ends of the fixed shaft 21, and the moving blocks are movably assembled in the slide rails. The slide rails are equipped with a motor screw assembly, and the moving blocks are arranged on the motor screw assembly.

[0036] When the cutter body 23 cuts the protrusion, two methods can be used. One method is to move the entire device downward to perform cutting, and the other method is to keep the entire device stationary and use the motor screw assembly to drive the cutter body 23 to move to complete the cutting work.

[0037] Specifically, if Figure 3 and Figure 5 As shown, the elasticity monitoring component 3 includes an arc tube 31 and an arc rod 32, the arc rod 32 is inserted into the arc tube 31, a spring 33 is fixedly installed between the inner end of the arc rod 32 and the inner end of the arc tube 31, a transmission block 34 is fixedly installed at the outer end of the arc rod 32, a rectangular groove is opened on the inner wall of the shell 1, a pressure sensor 35 is fixedly installed in the rectangular groove, and the transmission block 34 is fixedly installed on the pressure sensor 35.

[0038] The elasticity monitoring assembly 3 is installed on the inner wall of the housing 1 by fixing the transmission block 34 , the pressure sensor 35 and the rectangular groove.

[0039] When the fixed shaft 21 moves to the uppermost position in the slide rail, the fixed plate 25 contacts the lower end of the arc tube 31. At this time, when the knife body 23 deflects, it can drive the arc tube 31 to move on the arc rod 32 after transmission, and compress the spring 33 at the same time. The deformation of the spring 33 generates pressure on the pressure sensor 35. The pressure sensor 35 can determine the length of the protrusion by recording the pressure; when the pressure measured by the pressure sensor 35 is zero, it indicates that there is no protrusion on the wall.

[0040] Specifically, if Figure 1As shown, the limit assembly 4 includes a linear motor 41, a moving rod 43 and a top block 44. The linear motor 41 is fixedly installed on the inner wall of the shell 1, the moving rod 43 is fixedly installed on the output end of the linear motor 41, the outer end of the moving rod 43 is fixedly installed with the top block 44, and the outer end of the top block 44 faces the upper side of the surface of the knife body 23.

[0041] During the upward movement of the device, the linear motor 41 is in the initial position, at which time the top block 44 is away from the cutter body 23. When cutting the protrusion, the linear motor 41 is first controlled to run, driving the top block 44 to move to the cutter body 23, so that the cutter body 23 remains in a vertical state during cutting, and the cutting work can be performed more effectively.

[0042] Specifically, if Figure 1 As shown, the limit assembly 4 also includes a transmission plate 42 and a guide rod 45. The lower end of the transmission plate 42 is fixedly mounted on the collecting trough 5, and the upper end of the transmission plate 42 is fixedly mounted on the moving rod 43. The guide rod 45 is fixedly mounted on the inner wall of the shell 1, and the guide rod 45 is located below the linear motor 41, and the guide rod 45 passes through the transmission plate 42.

[0043] When the linear motor 41 is controlled to run, the transmission plate 42 is driven to move at the same time, thereby driving the collecting trough 5 to move to the bottom of the cutter body 23, so as to collect the protrusions that fall off after cutting.

[0044] Specifically, if Figure 1 , Figure 2 and Figure 4 As shown, the cleaning component 6 includes a cleaning shell 61, a motor 62, a driving wheel 63, a cleaning structure, a transmission belt 67 and a dust collecting box 69. The cleaning shell 61 and the dust collecting box 69 are respectively fixedly installed on the upper side of the inner wall of the shell 1, and the cleaning shell 61 and the dust collecting box 69 are opposite to each other. The cleaning shell 61 is located above the elastic monitoring component 3, the motor 62 is fixedly installed on the outer wall of the cleaning shell 61, and the output end of the motor 62 is fixedly installed with a driving wheel 63. Four groups of cleaning structures are rotatably assembled on the inner wall of the cleaning shell 61, and the cleaning structure is equipped with a driven wheel 64, and the transmission belt 67 is wound around the driving wheel 63 and the driven wheel 64. The interior of the cleaning structure is hollow, and the outer wall of the cleaning shell 61 is equipped with a dust duct 68 connected to the cleaning structure, and the outer end of the dust duct 68 is connected to the dust collecting box 69.

[0045] When the motor 62 is running, it drives the driving wheel 63 to rotate, and through the transmission of the transmission belt 67, it can drive the four driven wheels 64 to rotate, and then drive the rotating chamber 65 and the bristles 66 to rotate, so as to clean the wall surface. The dust during cleaning will directly enter the rotating chamber 65.

[0046] One end of the dust duct 68 is connected to the dust collecting box 69 , and the other end is provided with two branch pipes. The end of each branch pipe is further divided into two branch pipes, and each branch pipe is communicated with the corresponding rotating chamber 65 .

[0047] A negative pressure pump is provided at the connection between the dust collecting box 69 and the dust duct 68 to suck the dust in the rotating chamber 65 into the dust collecting box 69 .

[0048] Specifically, if Figure 1 and Figure 4 As shown, the cleaning structure includes a rotating chamber 65 and bristles 66. The interior of the rotating chamber 65 is hollow. The bristles 66 are arranged at the outer end of the rotating chamber 65. The driven wheel 64 is fixedly installed on the inner end of the rotating chamber 65, and the driven wheel 64 is hollow. The inner end of the driven wheel 64 is fixedly installed with a support tube that passes through the outer wall of the cleaning shell 61. The inner wall of the cleaning shell 61 is fixedly installed with a support ring, and the support tube passes through the support ring. The outer end of the support tube is rotatably assembled on the inner end of the dust duct 68.

[0049] The support tube and the support ring are used to support the rotating chamber 65 and ensure that the rotating chamber 65 can rotate. The support tube allows the dust in the rotating chamber 65 to flow into the dust duct 68.

[0050] In practical applications, a bracket can be arranged in the cleaning shell 61 to cooperate with the support ring to support the rotating chamber 65, and the rotating chamber 65 and the bracket are installed in a rotating assembly manner.

[0051] Specifically, if Figure 1 As shown, the cleaning shell 61 is inclined downward, and the inclination angle ranges from 1° to 3°.

[0052] The inclined setting of the cleaning shell 61 creates a gap on the upper side of the cleaning shell 61, allowing the wall to move smoothly to the inside of the bristles 66. During the upward movement of the device, the bristles 66 mainly use the lower half to perform cleaning work, ensuring that the cleaned dust is in the rotating chamber 65 and can be sucked into the dust collection box 69 under the action of negative pressure.

[0053] Specifically, if Figure 4 As shown, the driving wheel 63 and the driven wheel 64 are both provided with four wheel grooves, and different driven wheels 64 use different wheel grooves to wind the transmission belt 67, so as to ensure that each driven wheel 64 can be rotated under force without interfering with each other.

[0054] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present invention. As long as these changes do not deviate from the concept of the present invention, they all belong to the protection scope of the present invention.
