[0061] See also Figure 1 , Figure 5 as well as Figure 6 A roller seat 3 is movably provided on the fixed seat 2. Specifically, a linear guide rail is connected between the roller seat 3 and the fixed seat 2. A groove 22 is provided on the fixed seat 2. The linear guide rail is installed in the groove 22, and the slider of the linear guide rail is fixedly connected to the roller seat 3. On the two opposite side walls of the groove 22 (such as Figure 6 As shown, a limit block 23 is respectively arranged on the top wall and the bottom wall of the groove 22, and the limit block 23 can be made of nylon or polyethylene; a roller 31 is rotatably arranged on the roller seat 3, specifically, a rotating shaft is arranged on the roller 31, and the rotating shaft is movably arranged on the roller seat 3 through a bearing. In addition, it is a prior art and is not described again; a linkage plate 32 is fixedly arranged on the roller seat 3, and the linkage plate 32 can be made of a steel plate or an aluminum plate, and the ball head of the universal ball 821 is in contact with the top of the linkage plate 32; in addition, when the ball head of the universal ball 821 is in contact with the linkage plate 32, the bottom end of the roller 31 is lower than the bottom surface of the linkage plate 32, and at this time, the distance between the bottom surface of the linkage plate 32 and the bottom end of the roller 31 can be set to 1-3cm.

[0062] See also Figure 1-Figure 6 The rotating assembly 21 includes a driving motor 211, which is installed on the fixed base 2; the output shaft of the driving motor 211 is fixedly connected to the rotating shaft 212, and the rotating shaft 212 is movably connected to the fixed base 2 through a bearing, and the output shaft of the driving motor 211 is coaxial with the rotating shaft 212; the bottom end of the rotating shaft 212 is fixedly connected to the connecting disk 52, and the connecting disk 52 is also coaxial with the rotating shaft 212; by driving the rotating shaft 212 to rotate by the driving motor 211, the fixed disk 5 can be driven to rotate, thereby driving the spring member 4 to rotate around the axis of the rotating shaft 212, and then driving the first brush 6 and the second brush 7 to rotate.

[0063] The lifting assembly 11 includes a hydraulic cylinder 111 installed on the fixed seat 2, and the output end of the hydraulic cylinder 111 (i.e., the piston rod of the hydraulic cylinder) is fixedly connected to the fixed seat 2; since the fixed seat 2 is movably arranged on the support seat 1, when the output end of the hydraulic cylinder 111 is extended, it can drive the fixed seat 2 to move downward, and then drive the driving motor 211, the fixed plate 5, the spring part 4, the universal ball 821, etc. to move downward.

[0064] In this embodiment, when the sanitation vehicle is driving normally and not cleaning the shoulder stones, the telescopic mechanism or the connecting rod mechanism in the sanitation vehicle control system drives the support seat 1 to be at a suitable height, and the output end of the hydraulic cylinder 111 is in a retracted state (i.e., Figure 1 As shown in the state); since the roller seat 3 is movably arranged on the fixed seat 2, under the action of gravity, the roller seat 3 drives the slider of the corresponding linear guide to contact the limit block 23 below. At this time, the universal ball 821 contacts the linkage plate 32, and the spring member 4 is in a slightly compressed state; the slider is blocked by the limit block 23 to limit the roller seat 3, and the roller 31 does not contact the road surface at this time.

[0065] When cleaning the shoulder stone, the telescopic mechanism or connecting rod mechanism in the control system of the sanitation vehicle drives the support seat 1 to move, so that the roller 31 contacts the road surface, and at the same time drives the spring member 4 close to the shoulder stone, and makes the first brush 6 of the spring member 4 close to the side of the shoulder stone contact the side of the shoulder stone; then, the output end of the hydraulic cylinder 111 is controlled to extend downward to drive the fixed seat 2 to move downward, thereby driving the rotating assembly 21 and the fixed plate 5 to move downward; because the roller 31 contacts the road surface and the universal ball 821 contacts the linkage plate 32, the spring member 4 is further compressed as a whole, and the universal ball 821 presses against the linkage plate 32; by compressing the spring member 4 to a suitable length, the first brush 6 corresponding to the adjacent part of the spiral flexible strip 71 and the cylindrical portion 41 contacts the top surface of the shoulder stone, and when the spring member 4 rotates, it can simultaneously The side and top surfaces of the shoulder stones are cleaned; by setting appropriate spacing between adjacent circles of the cylindrical portion 41 and the conical portion 42, setting an appropriate taper for the conical portion 42, and setting appropriate lengths and angles for the first brush 6 and the second brush 7, when the spring member 4 is compressed, the interference between the first brushes 6 and the second brushes 7 is reduced (even if there is a certain interference between the first brushes 6 and the second brushes 7, it does not affect the cleaning of the shoulder stones by the first brush 6 and the second brush 7); the greater the compression of the conical portion 42, the more second brushes 7 are involved in the cleaning, that is, the larger the coverage radius of the second brush 7 during the cleaning process, so that the shoulder stones within a certain thickness range can be cleaned; in addition, since the spring member 4 is compressible, the shoulder stones within a certain height range can be cleaned.

[0066] Due to the provision of the universal ball 821, when the universal ball 821 contacts the linkage plate 32 and the spring member 4 is in a rotating state, it is easy to cause the ball head of the universal ball 821 to rotate, so that the spring member 4 can rotate stably under a compressed state; in addition, when the roller 31 passes through an uneven road surface, under the action of the spring member 4, it is easy for the universal ball 821 to always press against the linkage plate 32, and since the roller seat 3 is movably arranged on the fixed seat 2, the upper and lower positions of the roller 31 can be changed, so that the roller 31 is always in contact with the road surface, thereby improving the adaptability of the entire device; of course, the road surface undulation difference should not be too large, which is used to avoid excessive compression of the spring member 4 during the cleaning process of the first brush 6 and the second brush 7, thereby avoiding damage to the first brush 6, the second brush 7 and the spring member 4.

[0067] Embodiment 2

[0068] See also Figure 7 and Figure 8This embodiment is based on the first embodiment, and a piston cylinder 521 is coaxially arranged at the bottom of the connecting plate 52; a piston rod 5211 is fixedly connected to the end of the universal ball 821 away from the ball head, the piston rod 5211 is coaxial with the piston cylinder 521, and the head of the piston rod 5211 fits in the piston cylinder 521.

[0069] By the cooperation of the piston rod 5211 and the piston cylinder 521, the piston rod 5211 can be moved up and down; because the piston rod 5211 is connected to the universal ball 821, the universal ball 821 is connected to the fixed cylinder 82, and the cylindrical part 41 is fixedly connected to the fixed ring 81, when the spring part 4 rotates in a compressed state, the deviation of the spring part 4 can be reduced, thereby effectively improving the rotation stability of the spring part 4.

[0070] Embodiment 3

[0071] See also Figure 1-Figure 4 as well as Fig. 9 This embodiment is based on the second embodiment, in which a diverter pipe 9 is fixedly arranged on the fixed seat 2, a straight spray pipe 91 and a guide pipe 92 are arranged on the separation pipe, and a curved spray pipe 921 is arranged at one end of the guide pipe 92 away from the diverter pipe 9; the bottom end of the diverter pipe 9 is closed, and a water inlet 93 is arranged at the top end of the diverter pipe 9, and the water inlet 93 is connected to an external pressure water source through a conduit, so as to introduce the pressure water source into the diverter pipe 9, so as to realize the straight spray pipe 91 and the curved spray pipe 921 to spray water out.

[0072] The straight spray pipe 91 is used to spray water onto the side of the shoulder stone. There are at least two straight spray pipes 91, and an appropriate number can be set according to actual needs; the curved spray pipe 921 is used to spray water onto the top surface of the shoulder stone, and the straight spray pipe 91 and the curved spray pipe 921 first spray water onto the shoulder stone, and the first brush 6 and the second brush 7 then clean the part of the shoulder stone sprayed with water, thereby achieving the brushing treatment of the shoulder stone; in addition, the diversion pipe 9 can be connected to a spray pipe for flushing the first brush 6 and the second brush 7, thereby flushing the first brush 6 and the second brush 7, which can improve the brushing effect of the shoulder stone.
