[0033] About the unloading process of lifting mechanism 3: During the unloading process of the integrated sweeper 2, the hydraulic module provides power, and the lifting cylinder 306 of the lifting mechanism 3 rises, driving the inner door frame 303 to rise. The inner door frame 303 then drives the sliding frame 304 to rise synchronously through the plate chain assembly 309. According to the movable pulley principle, the rising height of the sliding frame 304 together with the quick-change structure 305 is twice the rising stroke of the lifting cylinder 306. During the rising process, the composite bearings assembled inside the inner door frame 303 and the first outer door frame 302 assist the two to slide against each other. The limit roller 311 simultaneously limits the sliding of the inner door frame 303 and the sliding frame 304, and jointly assists the inner door frame 303 and the sliding frame 304 to rise. The quick-change structure 305 is hung on the first hanging part 203 of the integrated sweeper 2. The quick-change lock pin 314 at the bottom of the quick-change structure 305 is connected to the pin sleeve, driving the integrated sweeper 2 to rise to the highest point. When the pull wire installed at the top of the inner door frame 303 When the sensor 315 senses that the cleaning system has risen to the highest point, it can prompt that the integrated sweeper 2 has risen to the right position. At this time, the unloading cylinder on the side extends out, driving the first unloading door 202 at the bottom to open to 60°, and the garbage in the material box 219 falls due to gravity. If there is stubborn garbage that is not easy to fall, the flip cylinder 307 of the quick-change structure 305 can continue to flip up, so that the integrated sweeper 2 can continue to flip up 20°. At this point, the unloading angle of the entire first unloading door 202 can reach 80°, completing the unloading of the garbage in the material box 219.

[0034] Installation process of the integrated sweeper 2 and the lifting mechanism 3: like Figure 5 , Figure 6 and Figure 7As shown, during the installation process, the lifting cylinder 306 is retracted to the shortest stroke, so that the inner door frame 303, the sliding frame 304, and the quick-change structure 305 of the lifting mechanism 3 are lowered to the lowest position. At this time, the flip cylinder 307 is controlled to extend to the maximum stroke, so that the quick-change structure 305 is flipped down to the lowest position, and then the cleaning equipment is controlled to move forward. When the surface of the steel pipe suspended at the upper end of the quick-change structure 305 reaches the lower opening end surface of the first hanger 203, the lifting cylinder 306 is controlled to extend to further raise the quick-change frame structure. When the steel pipe suspended at the upper end of the structure 305 rises to the first limit plate 217 of the first hanger 203, the turning cylinder 307 of the quick-change structure 305 is retracted, driving the quick-change structure 305 to turn up. Because the shaft of the quick-change cylinder 308 is welded to the shaft sleeve of the first hanger 203 and the first limit plate 217, when the front plane of the side plate of the quick-change structure 305 abuts against the surface of the first limit plate 217 at the lower inner side of the first hanger 203, the shaft of the quick-change cylinder 308 is in a concentric state with the shaft sleeve of the first hanger 203, as shown in FIG. Figure 7 As shown, at this time, the quick-change oil cylinder 308 is extended to drive the quick-change locking pin 314, which simultaneously penetrates into the shaft sleeve of the first hanging component 203 to complete the locking pin action, and the integrated cleaner 2 can enter the working state.

[0035] Working process of the integrated cleaner 2: like Fig.10 , Fig.11 , Fig.12 As shown, during the operation of the integrated sweeper 2, the hydraulic module provides hydraulic power to drive the drive motor 233 on the roller brush assembly 204. The drive motor 233 rotates to drive the first roller brush 232 on the roller brush to roll toward the material box 219. During this process, if the road is dry, the rubber baffle 216 will block the dust generated by the rolling inside the shell 201. The irregularly raised dust will be transferred from the dust suppression suction pipe 212 in the middle of the top of the shell 201 through the air duct transfer pipe 213, and the remaining dust will be sucked into the cleaning equipment through the exhaust fan installed on the main machine. During the cleaning process, Fig.11 As shown, before the medium-sized garbage enters the shell 201, it first passes through the bottom of the material receiving rubber plate 222. After the material receiving rubber plate 222 is rotated and flipped up by the hinge 224, the garbage completely enters the shell 201. At this time, due to the gravity of the adjustment pressure plate 223, the entire material receiving assembly will adaptively fall to the ground again to continue working. When the first roller brush 232 on the driving roller brush contacts the garbage, the garbage is swept along the material receiving rubber plate 222 to the inside of the material box 219, completing the entire garbage cleaning process. Example

[0036] This embodiment is further designed on the basis of the first embodiment, and has the functional modules and beneficial effects of the first embodiment. The obstacle avoidance mechanism includes an adjustment rod 111 installed on the obstacle avoidance frame 105 and an obstacle avoidance compression spring 112 sleeved on the adjustment rod 111.

[0037] like Figure 8 , Fig. 9 As shown, the net collector 1 is fixed to the front end of the integral sweeper 2, and is powered by the hydraulic module to extend the hydraulic cylinder 104 to flip the flip arm 102 downward until the hydraulic cylinder 104 reaches the maximum stroke, and under the action of the obstacle avoidance mechanism, the blade 108 installed on the obstacle avoidance frame 105 is close to the ground, and the lower front end of the blade 108 has a groove to make it perfectly close to the ground. At this time, the piston rod mounting shaft of the hydraulic cylinder 104 is at the rear end of the elongated hole of the ear plate of the flip arm 102 above the flip arm 102, and the structure in the working state is shown in FIG. Figure 8 ; After the cleaning device (which can be a cleaning vehicle) is slowly started and accelerated to a certain speed, when it reaches the large garbage, due to the inertia of the vehicle and the blade 108 in the ground state, the large garbage is scooped up and slides into the collection net 106 along the blade 108. Then the cleaning vehicle decelerates to a certain speed, the hydraulic cylinder 104 retracts, driving the flip arm 102 to flip up, and the blade 108 flips up together. At the same time, the collection net 106 and the collected large garbage are turned up and tightened, and the folded structure state is shown. Fig. 9 During the whole process, if there is an obstacle such as a ground bump or a speed bump, the blade plate 108 is blocked by the obstacle and flipped up, pressing the obstacle avoidance spring 112 of the obstacle avoidance mechanism to form a split obstacle avoidance. At the same time, if there is a larger obstacle, the entire flip arm 102 flips up to the rear end of the long hole of the ear plate of the flip arm 102 to form an integral obstacle avoidance. This process realizes double-layer obstacle avoidance and effectively ensures the safety of construction operations.
