When the walking roller 70 rotates, the walking wheel 71 is driven to rotate, so that the whole device moves on the runway. In order to reduce the movement resistance, the walking wheel 71 is set in a sheet shape, and multiple groups of cleaning brushes 61 are set on the cleaning roller 60. The cleaning brushes 61 point to both sides of the walking wheel 71. When the walking wheel 71 rotates, the synchronously rotating cleaning brushes 61 act on both sides of the walking wheel 71 to clean the side of the walking wheel 71, so as to avoid the spray material adhering to both sides of the walking wheel 71 and drying, causing the walking wheel 71 to gradually become heavier, thereby affecting the output power of the driving motor 4.

When the inner frame 6 and the outer frame 7 are relatively adjusted, the tensioning operation of the transmission belt 2 94 is realized in combination with the tensioning pulley 99 and the connecting spring 98, thereby ensuring the reliable power transmission between the transmission belt 2 94 and the pulley 1 90 and the pulley 2 91 , the pulley 3 92 and the pulley 4 93.

[0038] Further, such as Figure 1 , Figure 3As shown, the reversing assembly 2 includes a horizontal frame 23 arranged on the upper side of the mounting frame 1, a slide groove 24 is arranged in the horizontal frame 23, a mounting groove 21 is arranged on the horizontal frame 23, a handle 20 is rotatably installed in the mounting groove 21, a mounting slider 22 is arranged at the bottom of the mounting groove 21, the mounting groove 21 is slidably installed between the mounting slider 22 and the slide groove 24, two groups of telescopic clamping columns 25 are symmetrically arranged at both ends of the horizontal frame 23, the telescopic clamping columns 25 and the mounting groove 21 are lifted and locked, the reversing assembly 2 cooperates with the transfer mechanism 5 to realize the one hundred and eighty degree transfer of the inner frame 6 and the outer frame 7, and the transfer mechanism 5 is connected to the output shaft 40 of the drive motor 4.

[0039] Specifically, the reversing assembly 2 cooperates with the shifting mechanism 5 to realize a 180-degree shifting of the inner frame 6 and the outer frame 7. When the handheld handle 20 controls the equipment to spray materials and reaches the end of the runway, the locking relationship between the mounting groove 21 and the telescopic clamping column 25 is released, and the handle 20 and the mounting groove 21 slide in the slide groove 24 to the other end of the slide groove 24, and then combined with the shifting mechanism 5 to drive the inner frame 6 and the outer frame 7 to rotate as a whole, thereby realizing a 180-degree shifting of the equipment, and the operator continues to spray the runway with the spraying equipment.

[0040] Further, such as Figure 4 , Figure 5 As shown, the drive motor 4 is fixedly connected to the mounting shell 50, and the mounting shell 50 is fixedly connected through the outer frame 7 and the inner frame 6, a clutch 51 is arranged between the output shaft 40 of the drive motor 4 and the connecting shaft of the cleaning roller 60, and the indexing mechanism 5 includes an indexing wheel 52 on the output shaft 40 of the drive motor 4, and the indexing wheel 52 is connected to the output shaft 40 of the drive motor 4 through a tensioning assembly 53, and the tensioning assembly 53 includes a fixed bracket 530 arranged in the mounting shell 50, and a lifting motor 531 is arranged on the fixed bracket 530, and a mounting block 533 is arranged on the fixed bracket 530, and a first pulley 532 is arranged on the output shaft 40 of the drive motor 4, and the lifting A mounting shaft 539 is horizontally rotatably mounted on the output shaft 40 of the motor 531, the indexing wheel 52 is connected to the mounting shaft 539, a second pulley 538 is arranged on the mounting shaft 539, four sets of swing arms 534 are symmetrically arranged on the mounting block 533, rollers 535 are rotatably mounted on the ends of the swing arms 534, a transmission belt 536 is arranged between the first pulley 532, the roller 535 and the second pulley 538, a tensioning spring 537 is arranged between adjacent swing arms 534, the indexing mechanism 5 also includes a telescopic motor 10 arranged on the outer frame 7 on the side away from the driving motor 4, the telescopic motor 10 is vertically arranged, and the telescopic motor 10 is connected to a rotating fulcrum 11.

[0041] Specifically, after the reversing assembly 2 has completed the reversing of the handle 20, the clutch 51 is used to disconnect the power connection between the output shaft 40 and the cleaning roller 60. At this time, the lifting motor 531 controls the indexing wheel 52 on the mounting shaft 539 to descend until it contacts the runway surface. At the same time, the telescopic motor 10 on the other side of the outer frame 7 is extended so that the rotating fulcrum 11 contacts the road surface. Then the driving motor 4 is started, and the output shaft 40 drives the first pulley 532 to rotate. Combined with the transmission belt 536 and the roller 535 and the tensioning spring 537 on the swing arm 534, the second pulley 538 is driven to rotate, thereby transmitting power to the indexing wheel 52 of the mounting shaft 539. The entire device revolves around the rotating fulcrum 11. Driven by the rotation of the indexing wheel 52, it is adjusted 180 degrees so that the entire device is adjusted to the adjacent part of the area where the spraying has been completed, so as to continue the spraying operation.

[0042] Further, such as Figure 7 As shown, support wheels 600 are evenly and symmetrically arranged at the bottom of the inner frame 6, and the support wheels 600 are in contact with the runway.

[0043] Specifically, the support wheel 600 can improve the stability of the overall contact between the equipment and the road surface, and avoid damage to the nozzle 81 on the spray pipe 80 due to tilting during the spraying process.

[0044] The working principle of the embodiment of the present invention is:

[0045] like Figure 1-Figure 9As shown, the spray pipe 80 is movably installed through the vertical groove and the connecting slider 84, the supporting spring 86, the connecting shaft 87, and the spray pipe 80. When there are potholes on the runway surface, the height of the spray pipe 80 can be flexibly adjusted in combination with the contact roller 88 to avoid the nozzle 81 at the bottom of the spray pipe 80 from contacting the runway surface and causing damage. At the same time, the height of the nozzle 81 and the road surface is guaranteed to ensure the uniformity of spraying. The cleaning roller 60 is driven to rotate by the driving motor 4, and the walking roller 70 is driven to rotate synchronously in combination with the transmission assembly 9. When the walking roller 70 rotates, the walking wheel 71 is driven to rotate, so that the whole device moves on the runway. In order to reduce the moving resistance, the running wheel 71 is provided in a sheet shape, and multiple groups of cleaning brushes 61 are provided on the cleaning roller 60. The cleaning brushes 61 point to both sides of the running wheel 71. When the running wheel 71 rotates, the cleaning brushes 61 rotate synchronously act on both sides of the running wheel 71 to clean the sides of the running wheel 71, so as to avoid the spraying material adhering to both sides of the running wheel 71 and drying, causing the running wheel 71 to gradually become heavier, thereby affecting the output power of the driving motor 4. The inner frame 6 and the outer frame 7 are movably installed through the sliding rod 74 and the clamping groove 62, and are adjusted through the distance adjusting screw 72 and the distance adjusting motor 73. Through the adjustment between the inner frame 6 and the outer frame 7, the cleaning brushes 61 evenly arranged on the cleaning roller 60 are attached to the edge of the connecting shaft of the running wheel 71, so as to ensure that the spraying material adhering to the side of the running wheel 71 during the running process can be completely cleaned by the cleaning brushes 61. Among them, the adjustment groove 1 63 and the adjustment groove 2 75 are used to provide adjustment space for the inner frame 6 and the outer frame 7 when adjusting the spacing. The power transmission between the driving motor 4 and the cleaning roller 60 and the walking roller 70 is realized through the pulley 1 90, the pulley 2 91, the pulley 3 92, and the pulley 4 93. When the inner frame 6 and the outer frame 7 are relatively adjusted, the tensioning operation of the transmission belt 2 94 is realized in combination with the tensioning pulley 99 and the connecting spring 98, so as to ensure the reliable power transmission between the transmission belt 2 94 and the pulley 1 90, the pulley 2 91, the pulley 3 92, and the pulley 4 93. The reversing assembly 2 cooperates with the transfer mechanism 5 to realize the 180-degree transfer of the inner frame 6 and the outer frame 7. When the handheld handle 20 controls the equipment to spray materials and reaches the end of the runway, the locking relationship between the mounting groove 21 and the telescopic clamping column 25 is released, and the handle 20 and the mounting groove 21 slide in the slide groove 24 to the other end of the slide groove 24, and then the transfer mechanism 5 is combined to drive the inner frame 6 and the outer frame 7 to rotate as a whole, thereby realizing the 180-degree transfer of the equipment, and the operator continues to spray the runway with the spraying equipment.After the reversing assembly 2 has completed the reversing of the handle 20, the clutch 51 is used to disconnect the power connection between the output shaft 40 and the cleaning roller 60. At this time, the lifting motor 531 controls the indexing wheel 52 on the mounting shaft 539 to descend until it contacts the runway surface. At the same time, the telescopic motor 10 on the other side of the outer frame 7 is extended so that the rotating fulcrum 11 contacts the road surface. Then the driving motor 4 is started, and the output shaft 40 drives the first pulley 532 to rotate. Combined with the transmission belt 2 94 and the roller 535 and the tensioning spring 537 on the swing arm 534, the second pulley 538 is driven to rotate, thereby transmitting power to the indexing wheel 52 of the mounting shaft 539. The entire device revolves around the rotating fulcrum 11. Driven by the rotation of the indexing wheel 52, it is adjusted 180 degrees so that the entire device is adjusted to the adjacent part of the area where the spraying has been completed, so as to continue the spraying operation.
