[0011] Furthermore, the adaptive guiding mechanism further includes limit discs and first springs. The limit discs are fixedly connected to the upper ends of the sliding columns. First springs are fixedly connected between the limit discs and the vertically adjacent fixed plates. The first springs are all movably sleeved on the outer surface of the horizontally adjacent sliding columns, providing a driving force for the adaptive adjustment of the guiding cover according to environmental changes.

[0012] Furthermore, the adaptive moving mechanism includes support plates, telescopic columns, second springs, movable seats, and moving wheels.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: This seam cleaning machine has the following advantages:

[0017] 1. When the operator is using the joint cleaning machine, when the working plane is convex upward, the working plane squeezes the guide cover, causing the guide cover to slide upward at the lower end of the protective cover. The upward movement of the guide cover pushes the two sliding columns upward. The upward movement of the sliding columns causes the vertically adjacent limit disks to move upward, increasing the distance between the limit disk and the vertically adjacent fixed plate. As a result, the first spring is elastically stretched. When the joint cleaning machine passes through the convex area of the working surface, the elastic force of the first spring pulls the vertically adjacent limit disk downward, causing the corresponding sliding column to slide downward, thereby resetting the guide cover. This ensures that the bottom surface of the guide cover always adheres tightly to the working surface during operation, providing a guiding function for the joint cleaning and dust suction work, effectively preventing dust from splashing, enabling the guiding unit to quickly adapt to changes in the working environment, and effectively improving the joint cleaning effect of the joint cleaning machine.

[0018] 2. When the operator is using the joint cleaning machine, when the adaptive moving mechanism passes over the convex working surface, the moving wheel pushes the vertically adjacent movable seat upward during the rolling process, causing the telescopic ends of the vertically adjacent telescopic columns to contract, and at the same time causing the corresponding second spring to elastically contract. When the adaptive moving mechanism passes through the convex working surface, the elastic force of the second spring pushes the movable seat downward, and at the same time causes the telescopic ends of the corresponding telescopic columns to extend to their original state. The downward movement of the movable seat drives the corresponding moving wheel downward, thereby resetting the moving wheel, achieving the smooth movement of the joint cleaning machine on different working planes, effectively improving the joint cleaning effect of the joint cleaning machine, enabling the moving unit to quickly adapt to changes in the working environment, and effectively improving the joint cleaning effect of the joint cleaning machine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] Please refer to Figures 1-5 , this embodiment provides a technical solution: a seam cleaning machine, including a drive chamber 1, an adaptive guiding mechanism 3, and an adaptive moving mechanism 4;

[0027] Drive chamber 1: A dust suction chamber 2 is fixedly connected to the rear end thereof. A protective cover 5 is fixedly connected to the right end of the drive chamber 1. A rotating shaft 6 is rotatably connected inside the protective cover 5. A mounting seat 7 is fixedly connected to the middle of the rotating shaft 6. A cleaning disk 8 is connected to the inside of the mounting seat 7 by screws. A handle 12 is fixedly connected to the upper end of the dust suction chamber 2. A cavity is provided inside the handle 12. A control switch group 14 is provided at the upper end of the cavity. The input end of the control switch group 14 is electrically connected to an external power source. A motor 9 is provided inside the drive chamber 1. The output shaft of the motor 9 is fixedly connected to the left end of the rotating shaft 6. The input end of the motor 9 is electrically connected to the output end of the control switch group 14;

[0028] Adaptive guiding mechanism 3: It is arranged at the lower end of the protective cover 5. The adaptive guiding mechanism 3 includes a fixing plate 31, a sliding column 32, and a guiding cover 35. The fixing plates 31 are respectively fixedly connected to the front and rear ends of the protective cover 5. The sliding columns 32 are slidably connected inside the fixing plates 31. The lower ends of the sliding columns 32 are fixedly connected to the upper end of the guiding cover 35. The inner wall of the guiding cover 35 is slidably connected to the lower surface of the outer surface of the protective cover 5. The adaptive guiding mechanism 3 further includes a limiting disk 33 and a first spring 34. The limiting disks 33 are fixedly connected to the upper ends of the sliding columns 32. A first spring 34 is fixedly connected between the limiting disk 33 and the vertically adjacent fixing plate 31. The first spring 34 is movably sleeved on the outer surface of the horizontally adjacent sliding column 32. When the working plane bulges upward, the working plane presses the guiding cover 35, causing the guiding cover 35 to slide upward at the lower end of the protective cover 5. The upward movement of the guiding cover 35 pushes the two sliding columns 32 upward. The upward movement of the sliding columns 32 causes the vertically adjacent limiting disks 33 to move upward. The distance between the limiting disk 33 and the vertically adjacent fixing plate 31 increases, thereby causing the first spring 34 to be elastically stretched. When the seam cleaning machine passes through the bulging area of the working surface, the elastic force of the first spring 34 pulls the vertically adjacent limiting disk 33 downward, thereby causing the corresponding sliding column 32 to slide downward, thereby realizing the reset of the guiding cover 35, so that the bottom surface of the guiding cover 35 always adheres to the working surface during the working process, providing a guiding function for the seam cleaning and dust suction work, and effectively avoiding dust splashing;

[0029] Adaptive moving mechanism 4: It is symmetrically arranged at the left and right ends of the dust suction bin 2. The adaptive moving mechanism 4 includes a support plate 41, a telescopic column 42, a second spring 43, a movable seat 44 and a moving wheel 45. The support plates 41 are respectively symmetrically and fixedly connected to the lower ends of the left and right side surfaces of the dust suction bin 2. Two telescopic columns 42 are fixedly connected to the lower ends of the support plates 41. The telescopic ends of two longitudinally adjacent telescopic columns 42 are fixedly connected to the upper end of the same movable seat 44. Two moving wheels 45 are rotatably connected to the lower ends of the movable seats 44. A second spring 43 is arranged between the bottom surface of the support plate 41 and the upper surface of the movable seat 44. The second springs 43 are sleeved on the outside of the telescopic columns 42. When the adaptive moving mechanism 4 passes through a convex working surface, the moving wheels 45 push the vertically adjacent movable seats 44 to move upward during the rolling process, thereby causing the telescopic ends of the vertically adjacent telescopic columns 42 to contract, and at the same time causing the corresponding second springs 43 to elastically contract. When the adaptive moving mechanism 4 passes through the convex working surface, the elastic force of the second spring 43 pushes the movable seat 44 to move downward, and at the same time causes the telescopic ends of the corresponding telescopic columns 41 to extend to the original state. The downward movement of the movable seat 44 drives the corresponding moving wheels 45 to move downward, thereby realizing the reset of the moving wheels 45, and further realizing the stable movement of the seam cleaning machine on different working planes, effectively improving the seam cleaning effect of the seam cleaning machine;

[0030] Wherein: A dust suction pipe 11 is arranged between the protective cover 5 and the dust suction bin 2. A dust suction pump 10 is arranged on the rear wall of the dust suction bin 2. The rear end of the dust suction pipe 11 is communicated with the air inlet of the dust suction pump 10. The left end of the dust discharge pipe 13 is threadedly connected to the rear end of the right side surface of the dust suction bin 2. The left end of the dust discharge pipe 13 is communicated with the air outlet of the dust suction pump 10. The input end of the dust suction pump 10 is electrically connected to the output end of the control switch group 14. The operation of the motor 9 is realized through the control switch group 14. The output shaft of the motor 9 rotates to drive the rotating shaft 6 to rotate, and then drives the mounting seat 7 to rotate, finally realizing the rotation of the cleaning disc 8, and further realizing the seam cleaning work at the construction site. At the same time, the operation of the dust suction pump 10 is realized through the control switch group 14. The dust suction pump 10 generates a backward suction force inside the dust suction pipe 11. The dust stirred up by the cleaning disc 8 enters the dust suction pump 10 through the dust suction pipe 11, and then moves to the external collection bag through the dust discharge pipe 13.

[0031] The working principle of a seam cleaning machine provided by the present utility model is as follows: During operation, first, an operator places the seam cleaning machine in the working area through the handle 12. After it is stably placed, the operator starts the motor 9 through the control switch group 14. The rotation of the output shaft of the motor 9 drives the rotation of the rotating shaft 6, which in turn drives the rotation of the mounting seat 7, and finally realizes the rotation of the cleaning disc 8, thereby achieving the seam cleaning work at the construction site. At the same time, the dust suction pump 10 is started through the control switch group 14. The dust suction pump 10 generates a backward suction force inside the dust suction pipe 11. The dust stirred up by the cleaning disc 8 enters the dust suction pump 10 through the dust suction pipe 11 and then moves to the external collection bag through the dust outlet pipe 13. During the movement of the seam cleaning machine, when the working plane is convex upward, the working plane presses against the guiding cover 35, causing the guiding cover 35 to slide upward at the lower end of the protective cover 5. The upward movement of the guiding cover 35 pushes the two sliding columns 32 upward. The upward movement of the sliding columns 32 causes the vertically adjacent limiting discs 33 to move upward, increasing the distance between the limiting disc 33 and the vertically adjacent fixing plate 31, thereby elastically stretching the first spring 34. When the seam cleaning machine passes through the convex area of the working surface, the elastic force of the first spring 34 pulls the vertically adjacent limiting disc 33 downward, causing the corresponding sliding column 32 to slide downward, thereby realizing the reset of the guiding cover 35, and ensuring that the bottom surface of the guiding cover 35 always adheres to the working surface during operation, providing a guiding function for the seam cleaning and dust suction work, effectively avoiding dust splashing. At the same time, when the adaptive moving mechanism 4 passes through the convex working surface, the moving wheel 45 pushes the vertically adjacent movable seat 44 upward during the rolling process, causing the telescopic ends of the vertically adjacent telescopic columns 42 to contract, and at the same time causing the corresponding second spring 43 to elastically contract. When the adaptive moving mechanism 4 passes through the convex working surface, the elastic force of the second spring 43 pushes the movable seat 44 downward, and at the same time causes the telescopic ends of the corresponding telescopic columns 41 to extend to the original state. The downward movement of the movable seat 44 drives the corresponding moving wheel 45 downward, thereby realizing the reset of the moving wheel 45, and achieving the stable movement of the seam cleaning machine on different working planes, effectively improving the seam cleaning effect of the seam cleaning machine.

[0032] It should be noted that in the above embodiments, the motor 9 disclosed can be a 400T brushless motor, the dust suction pump 10 can be a QB-320 dust suction pump, and the control switch group 14 is provided with control buttons corresponding to the motor 9 and the dust suction pump 10 one by one to control their switches.

[0033] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
