The movable shield 1 opens downward, and the other end of each scraper 3 extends out of the lower opening of the movable shield 1 as the scraper wheel 2 rotates, and the angle between the scraper 3 and the tangent direction of the scraper wheel 2 is an acute angle. The receiving box 5 is located at the rear side of the scraper wheel 2 and opens upward.

[0022] When widening the crack and taking out the debris in the crack, the scraper 3 can be extended into the crack, and then the scraper wheel 2 can be driven to rotate by the motor 4, so that the scraper 3 scrapes the debris in the crack, and as the scraper wheel 2 rotates, the debris is brought into the receiving box 5, so as to improve the technical problems of low efficiency of manual cleaning of debris in the crack groove, inconvenience in collecting debris, and harm to the health of construction workers. In this process, the movable shield 1 can reduce the dispersion of dust, so as to reduce the dispersion of dust, and improve the technical problems of low efficiency of manual cleaning of debris in the crack groove, inconvenience in collecting debris, and harm to the health of construction workers.

[0023] As a parallel solution, the circumferential ends of the scraper 3 and the scraper wheel 2 can enter the crack at the same time. In this solution, the installation position of the scraper wheel 2 is relatively lower.

[0024] Obviously, as the movable shield 1 moves forward, the scraper 3 can push part of the debris forward while scraping the debris, so as to facilitate centralized cleaning in the final stage.

[0025] On the basis of the above solution, the scraper 3 is an arc plate, the middle end of which is bent outwards in a direction away from the scraper wheel 2 to improve the scraping and filtering of debris and reduce the probability of debris sliding off the scraper 3.

[0026] A baffle plate 31 is connected between two adjacent scrapers 3 . The two baffle plates 31 are respectively located at two axial ends of the scraper wheel 2 , and each baffle plate 31 is fixedly connected to the radial side of the scraper wheel 2 .

[0027] In the process of scraping the debris by the scraper 3, as the scraper wheel 2 rotates, the debris is collected in the space formed by the two scrapers 3 and the two baffles 31, reducing the debris falling from between the two scrapers 3 and ensuring that the debris falls into the receiving box 5 as much as possible.

[0028] As a specific solution of an embodiment of the present application, a plurality of universal wheels are fixedly connected to the lower end of the mobile shield 1, and a push rod is fixedly connected to the rear end of the mobile shield 1, so that the mobile shield 1 can be pushed by the push rod and the universal wheels can be used to realize rapid movement of the mobile shield 1.

[0029] A fixing rod is also fixedly connected to the side of the receiving box 5 , and the fixing rod is fixedly connected to the inner wall of the movable shield 1 to achieve the installation of the receiving box 5 .

[0030] On the basis of the above solution, a universal wheel (not shown in the figure) may be installed at the bottom of the receiving box 5 to support the receiving box 5 by docking.

[0031] On the basis of the above scheme, an avoidance groove 51 is opened on the side of the receiving box 5 close to the scraper wheel 2, and there is a distance between the avoidance groove 51 and the bottom of the receiving box 5, so that the scraper 3 can pass through the avoidance groove 51 when rotating, to ensure that the debris falling from the scraper 3 can enter the receiving box 5.

[0032] The bottom of the receiving box 5 is an inclined surface, and is tilted downward in a direction away from the scraper wheel 2 , so that the debris falling into the receiving box 5 continues to roll and accumulate in a direction away from the scraper wheel 2 .

[0033] Reference Figures 1 to 3 The scraper wheel 2 is coaxially fixedly connected with a rotating shaft 6, and both ends of the rotating shaft 6 are rotatably connected to the movable shield 1 through bearings, so as to form a rotating support for the scraper wheel 2 through the rotating shaft 6.

[0034] The rotating shaft 6 includes two sliding sleeves 61, one end of which is rotatably connected to the movable shield 1, and a sliding rod 62. The cross-sections of both ends of the sliding rod 62 are polygonal and are respectively slidably connected to the other ends of the two sliding sleeves 61. The scraper wheel 2 is coaxially fixedly connected to the sliding rod 62. When the scraper 3 extends into the crack and scrapes the debris, the curved crack can apply thrust to the scraper 3, so that the scraper wheel 2 and the sliding rod 62 slide adaptively at the same time, so that there is no need to take out the entire device and then put it into the crack, thereby improving the cleaning efficiency.

[0035] The sliding sleeve 61 is rotatably connected to the movable shield 1 via a bearing.

[0036] On the basis of the above embodiment, the end of the sliding rod 62 slidably connected to the sliding sleeve 61 is in a “T” shape to prevent the sliding sleeve 61 and the sliding rod 62 from being separated.

[0037] A suspension rod 611 is fixedly connected to both sleeves 61 , the lower end of the suspension rod 611 is fixedly connected to the sleeve 61 , and the upper end is fixedly connected to the movable shield 1 , so that the two suspension rods 611 form a support for the rotating shaft 6 to ensure stable operation of the scraper wheel 2 and the scraper 3 .

[0038] Reference Figures 2 to 5 , both ends of the slide rod 62 of the rotating shaft 6 have external threads with opposite rotation directions; the scraper wheel 2 includes two center wheels 21, multiple support rods 22 and a side ring 23, the two center wheels 21 are coaxially threadedly connected to the two ends of the slide rod 62 of the rotating shaft 6, and both center wheels 21 have multiple support rods 22 evenly distributed circumferentially, one end of the multiple support rods 22 is rotatably connected to the radial end of the side ring 23, and the other end of the support rod 22 is rotatably and slidably connected to the center wheel 21.

Specifically, in this process, the support bars 22 can be used to scrape off the debris on the side wall of the crack.

[0040] The plurality of support rods 22 may be two, three, four or five, etc. One end of the support rod 22 close to the edge ring 23 is plate-shaped, and a brush 221 is fixedly connected to the outside, so that the brush 221 can be used to clean the side of the crack during the rotation of the scraper wheel 2 to improve the cleaning effect.

[0041] Both sides of the two center wheels 21 are provided with limit nuts 63 threadedly connected to the rotating shaft 6, so as to prevent the center wheels 21 from automatically moving relative to the rotating shaft 6 through the limit nuts 63. Furthermore, a gasket (not shown in the figure) is placed in front of the limit nuts 63.

[0042] The center wheel 21 is radially provided with a plurality of slots 211 facing the axis, and the slots 211 are adapted and slidably connected with the block 24, the block 24 is rotatably connected with the fixing ball 25, and the other end of the support rod 22 is fixedly connected to the fixing ball 25. When adjusting the distance between the two center wheels 21, the block 24 is slidably connected to the slots 211, and the support rod 22 rotates relative to the block 24 through the fixing ball 25.

[0043] As a specific solution of the embodiment of the present application, the clamping groove 211 is a stepped groove, and the clamping groove 211 does not penetrate the radial outer side of the center wheel 21 to prevent the clamping block 24 from escaping from the center wheel 21 .

[0044] An end slot 212 connected to the clamping slot 211 is provided at the end of the center wheel 21, so that the rotating support rod 22 can enter. The fixed ball 25 is simultaneously rotatably connected to the clamping block 24 near the end side and the outer side of the center wheel 21, so that the support rod 22 can be rotated to be perpendicular to the side ring 23, thereby realizing the debris removal operation of the U-shaped crack.

[0045] A plurality of rotating seats 26 are circumferentially fixed to both axial ends of the side ring 23, and one end of the support rod 22 is rotatably connected to the rotating seat 26. When adjusting the spacing between the two center wheels 21, the support rod 22 rotates relative to the side ring 23 through the rotating seat 26.

[0046] Reference Figure 2 and Figure 6 A dust hood 7 fixedly connected to the inner side of the movable protective cover 1 is provided on the rear side of the receiving box 5.

[0049] The suction fan 72 can be purchased from the market and is fixedly installed on the top of the movable protective cover 1 through a support.

[0050] Before cleaning the debris, fill the dust collecting pool 73 with water until the other end of the dust removal pipe is submerged. During use, turn on the suction fan 72 and suck out the dust generated during the cleaning process, so that the dust is poured into the liquid in the dust collecting pool 73 from the dust hood 7, the dust collection pipe 71, the suction fan 72 and the dust outlet pipe in sequence to achieve cleaning.

[0051] On the basis of the above embodiment, a one-way valve (not shown in the figure) is installed on the dust outlet pipe to prevent the liquid from flowing back.

[0052] The dust suction pipe 71 is slidably connected to a filter plate 711, which is slidably connected to the dust suction pipe 71 along the cross-sectional direction of the dust suction pipe 71, and the middle end of the dust suction pipe 71 is connected to a slag box 712, which is located on the side of the filter plate 711 away from the suction fan 72. During the dust removal process, the filter plate 711 blocks large dust particles, and the blocked dust falls into the slag box 712 to be collected.
