A fourth gear 127 is fixedly installed on the sliding shaft 126, and the fourth gear 127 can mesh with the third gear 125. An annular frame 128 is sleeved on the end wall of the sliding shaft 126 located outside the gearbox body 121, and the annular frame 128 can rotate relative to the sliding shaft 126. By driving the cylinder 129, the cooperation between the sliding shaft 126 and the third rotating shaft 131 can be changed, disconnecting them during transportation and making the sliding shaft 126 cooperate with the third rotating shaft 131 during cleaning.

[0044] In this embodiment, as Figures 12 to 14As shown in the figure, a loading shell 130 is fixedly installed on the inner wall of the middle part of the upper cover shell 110. A third rotating shaft 131 is rotatably connected to the inner wall of the loading shell 130. An inner slot 132 is formed in the inner wall of the front end of the third rotating shaft 131. The inner slot 132 is used in cooperation with the end of the sliding shaft 126. When the inner slot 132 is in cooperation with the sliding shaft 126, the rotation of the sliding shaft 126 can drive the third rotating shaft 131 to rotate. A fifth gear 133 is rotatably connected to the inner wall of the loading shell 130. A third helical gear set 134 is installed on both the fifth gear 133 and the third rotating shaft 131. And the third rotating shaft 131 is in transmission connection with the fifth gear 133 through the third helical gear set 134. A fourth rotating shaft 135 is rotatably connected to the bottom of the loading shell 130. And the fourth rotating shaft 135 penetrates through the loading shell 130. A sixth gear 136 is fixedly installed on the fourth rotating shaft 135. And the sixth gear 136 is meshed with the fifth gear 133. There are two groups of first cleaning rollers 140, and they are respectively fixedly connected to both ends of the fourth rotating shaft 135. In the present invention, the sliding shaft 126 is in cooperation with the third rotating shaft 131, which can drive the third rotating shaft 131 to rotate synchronously, so that the third helical gear set 134 meshes, thereby driving the fifth gear 133 and the sixth gear 136 to mesh, so that the fourth rotating shaft 135 fixedly connected to the sixth gear 136 rotates, and the rotation speed is the same as that of the first gear 123.

[0045] In this embodiment, as Figures 15 to 17As shown in the figure, a side seat 111 is fixedly installed on the outer wall of the left side of the upper cover 110. A first rotating shaft 112 is rotatably connected to the inner wall of the side seat 111. The side seat 111 supports the first rotating shaft 112. An external end wall of the first rotating shaft 112 and an external end wall of the fourth rotating shaft 135 are provided with the same first bevel gear set 113, and the first rotating shaft 112 is drivingly connected to the fourth rotating shaft 135 through the first bevel gear set 113. A second rotating shaft 114 is rotatably connected to the inner wall of the middle part of the upper cover 110. An external end wall of the second rotating shaft 114 and an other end wall of the first rotating shaft 112 are provided with the same second bevel gear set 115, and the second rotating shaft 114 is drivingly connected to the first rotating shaft 112 through the second bevel gear set 115. A protective cover 116 is fixedly installed on the outer wall of the upper cover 110, and both the fourth rotating shaft 135 and the second rotating shaft 114 rotatably penetrate through the protective cover 116. The protective cover 116 can protect the operation of the first bevel gear set 113 and the second bevel gear set 115. The second cleaning roller 150 is fixedly connected to the second rotating shaft 114 located inside the upper cover 110. In the present invention, the rotation of the fourth rotating shaft 135 can drive the external first bevel gear set 113 to engage, thereby driving the first rotating shaft 112 to rotate, so that the second bevel gear set 115 at the other end of the first rotating shaft 112 engages, thereby driving the second rotating shaft 114 to rotate, and the rotation speed is the same as that of the fourth rotating shaft 135. At this time, the first cleaning roller 140 and the second cleaning roller 150 on the fourth rotating shaft 135 and the second rotating shaft 114 can rotate, so as to clean the ground. At the same time, under the action of the first bevel gear set 113 and the second bevel gear set 115, the rotation directions of the first cleaning roller 140 and the second cleaning roller 150 are opposite, so that the first cleaning roller 140 rotates counterclockwise and the second cleaning roller 150 rotates clockwise.

[0046] As an implementation method in this embodiment, as Figure 18 and Figure 19 shown, a second scraper 170 is fixedly installed on the inner wall of the top of the upper cover 110, and the second scraper 170 is used in cooperation with the first cleaning roller 140. The second scraper 170 can scrape off the garbage on the first cleaning roller, so that it falls onto the second cleaning roller 150. A first scraper 161 is fixedly installed on the outer end wall of the storage area 160, and the first scraper 161 is used in cooperation with the second cleaning roller 150. The first scraper 161 can sweep the garbage on the second cleaning roller 150 into the storage area 160. In the present invention, the first cleaning roller 140 can sweep up the garbage on the ground. At the same time, after the garbage on the first cleaning roller 140 contacts the second scraper 170, the garbage on the first cleaning roller 140 can be swept off. After the swept-off garbage and the garbage on the first cleaning roller 140 float in the air, they will fall onto the second cleaning roller 150, and thus are scraped off by the first scraper 161 at the end of the second cleaning roller 150, and finally fall into the storage area 160.

[0047] In this embodiment, as Figures 3 to 5As shown in the figure, sealing cylinders 211 are fixedly installed on the inner walls of both sides of the top of the vehicle body 210. A plug column 212 is hermetically slidably connected to the inner wall of the sealing cylinder 211. A ball groove 213 is formed in the end wall of the plug column 212. Hydraulic cylinders 214 are rotatably connected to the end walls on both sides of the vehicle body 210, and the output ends of the hydraulic cylinders 214 are rotatably connected to the side walls of the corresponding plug columns 212. A ball column 215 is clamped in the inner wall of the ball groove 213, and the ball column 215 is movably connected to the plug column 212. The ball column 215 and the plug column 212 are connected by clamping the ball column 215 in the ball groove 213 to ensure that the ball column 215 can move in all directions. Thus, when cleaning the dead corners on the ground, the upper cover 110 can also swing up and down. The outer ends of the two ball columns 215 are rotatably connected to the same triangular push plate 220, and the triangular push plate 220 is fixedly connected to the inner wall of the upper cover 110. In the present invention, when cleaning a relatively narrow ground, only a small vehicle can be used to drag this machine, but there will be cleaning dead corners at the road surface corners. At this time, according to the turning direction of the corner, the corresponding hydraulic cylinder 214 is driven to drive the plug column 212 to slide, so that the plug column 212 drives the ball column 215 to move, thereby pushing the triangular push plate 220 to rotate, so that the upper cover 110 swings left and right, so as to be able to clean each road surface dead corner. At the same time, cooperating with the hydraulic cylinder 232 can make the upper cover 110 swing in all directions for cleaning.

[0048] As an implementation manner in this embodiment, as Figures 5 to 8 shown, a connecting rod 230 is rotatably connected to the side wall of the top of the vehicle body 210. A rocker 231 is rotatably connected to the end wall of the connecting rod 230, and the rotation direction of the rocker 231 is perpendicular to that of the connecting rod 230. The rocker 231 is rotatably connected to the top of the upper cover 110. The rotation of the upper cover 110 is the same as the rotation trend of the connecting rod 230. A hydraulic cylinder 232 is rotatably connected to the top of the vehicle body 210, and the output end of the hydraulic cylinder 232 is rotatably connected to the middle of the connecting rod 230. In the present invention, when on an uphill or downhill section, the hydraulic cylinder 232 is adjusted according to the slope and direction of the slope, so that the output end of the hydraulic cylinder 232 drives the connecting rod 230 to swing up and down, thereby driving the upper cover 110 to swing up and down, ensuring that the first cleaning roller 140 and the second cleaning roller 150 can always be in contact with the ground and ensuring good cleaning results.

[0049] In this embodiment, as Figure 7 and Figure 11As shown in the figure, a drive axle 240 is installed at the bottom of the vehicle body 210, and both ends of the drive axle 240 are respectively connected to two groups of wheels of the vehicle body 210 in a transmission manner. The drive axle 240 is a mechanism located at the end of the transmission system that can change the rotational speed and torque from the transmission and transmit them to the drive wheels. In the present invention, the drive axle 240 can transmit the torque of the wheels at the bottom of the vehicle body 210 to the universal drive shaft 250. A universal drive shaft 250 is installed at the output end in the middle of the drive axle 240, and the other end of the universal drive shaft 250 is fixedly connected to the input end of the planetary gear set 122.

[0050] The working principle of the technical solution provided by the present invention is as follows: When transporting the machine, the operator connects the lead rod 260 to the target vehicle. After that, the driving cylinder 129 drives the sliding shaft 126 to move backward and separates the sliding shaft 126 from the rotating shaft three 131. At this time, by starting the target vehicle, the function of transporting the machine can be achieved.

[0051] When the machine is working, the operator drives the cylinder 129 so that the sliding shaft 126 cooperates with the third rotating shaft 131. At this time, the target vehicle is started to drive the vehicle body 210 to move. The torque can be transmitted to the drive axle 240 through the two groups of wheels of the vehicle body 210, thereby driving the universal drive shaft 250 to rotate, making the universal drive shaft 250 drive the planetary gear set 122 to work, thereby driving the first gear 123 to rotate. And the rotation speed of the first gear 123 is much greater than that of the universal drive shaft 250. At the same time, the first gear 123 can mesh with the belt shaft second gear 124, thereby driving the third gear 125 to rotate at the same speed, making the third gear 125 mesh with the fourth gear 127, thereby driving the sliding shaft 126 to rotate. At the same time, the sliding shaft 126 cooperates with the third rotating shaft 131, which can drive the third rotating shaft 131 to rotate synchronously, making the third helical gear set 134 mesh, thereby driving the fifth gear 133 to mesh with the sixth gear 136, making the fourth rotating shaft 135 fixed to the sixth gear 136 rotate, and the rotation speed is the same as that of the first gear 123. At the same time, the rotation of the fourth rotating shaft 135 can drive the first helical gear set 113 at the outer end to mesh, thereby driving the first rotating shaft 112 to rotate, making the second helical gear set 115 at the other end of the first rotating shaft 112 mesh, thereby driving the second rotating shaft 114 to rotate, and the rotation speed is the same as that of the fourth rotating shaft 135. At this time, the first cleaning roller 140 and the second cleaning roller 150 on the fourth rotating shaft 135 and the second rotating shaft 114 can rotate, thereby cleaning the ground. At the same time, under the action of the first helical gear set 113 and the second helical gear set 115, the rotation directions of the first cleaning roller 140 and the second cleaning roller 150 are opposite, making the first cleaning roller 140 rotate counterclockwise and the second cleaning roller 150 rotate clockwise. At this time, the first cleaning roller 140 can sweep up the garbage on the ground. At the same time, after the garbage on the first cleaning roller 140 contacts the second scraper 170, the garbage on the first cleaning roller 140 can be swept off. The swept garbage and the garbage on the first cleaning roller 140 will float in the air and then fall onto the second cleaning roller 150, and thus be scraped off by the first scraper 161 at the end of the second cleaning roller 150, and finally fall into the storage area 160;

[0052] When on uphill and downhill sections, the hydraulic cylinder two 232 is adjusted according to the slope and direction of the slope, so that the output end of the hydraulic cylinder two 232 drives the connecting rod 230 to swing up and down, thereby driving the upper cover 110 to swing up and down, ensuring that the first cleaning roller 140 and the second cleaning roller 150 can always be in contact with the ground, guaranteeing good cleaning results. When cleaning a relatively narrow ground, only a small vehicle can be used to drag this machine, but there will be cleaning dead corners at the road surface corners. At this time, according to the turning direction of the corner, the corresponding hydraulic cylinder one 214 is driven to drive the plug column 212 to slide, so that the plug column 212 drives the ball column 215 to move, thereby pushing the triangular push plate 220 to rotate, making the upper cover 110 swing left and right, so as to be able to clean each road surface dead corner, and at the same time, cooperating with the hydraulic cylinder two 232 can make the upper cover 110 swing and clean in all directions.
