The other end of the sweeping disc telescopic device 51 is connected with the sweeping disc rotating shaft sleeve, and the sweeping disc telescopic device 51 is used for driving the sweeping disc rotating shaft connecting sleeve 523 to rotate clockwise or anticlockwise around the sweeping disc rotating shaft 524.

Specifically, the sweeping disk rotating shaft fixing member 522 is fixed to a side surface of an extending end of the connecting frame 2, and the sweeping disk connecting sleeve is connected to the sweeping disk rotating shaft fixing member 522 through the sweeping disk rotating shaft 524.

By controlling the extension range of the sweeping tray assembly 52, the sweeping tray 5261 can sweep more flexibly and can sweep garbage on the road surface in a wider range.

According to some embodiments of the present application, optionally, as shown in fig. 6, the tray cleaning expansion device 51 further includes an expansion limit screw 511 and an expansion limit nut 512. The connecting sleeve 523 of the sweeping disk rotating shaft is provided with a telescopic limiting hole at the position of the sweeping disk rotating shaft 524, and the telescopic limiting nut 512 is arranged at the telescopic limiting hole. The telescopic limiting screw 511 passes through the telescopic limiting nut 512 and the telescopic limiting hole, and the telescopic limiting screw 511 is used for adjusting the angle of the connecting sleeve 523 of the sweeping disk rotating shaft rotating around the sweeping disk rotating shaft 524 in a clockwise rotation manner by adjusting the length of the convex sweeping disk rotating shaft 524.

Wherein, in order to limit the outward extending position of the sweeping disk connecting sleeve, the position of the sweeping disk rotating shaft 524 is correspondingly arranged. The sweeping disk rotating shaft connecting sleeve 523 is provided with a telescopic limiting hole at the sweeping disk rotating shaft 524, the telescopic limiting nut 512 is fixed at the telescopic limiting hole, one telescopic limiting nut can be respectively arranged at two sides of the telescopic limiting hole, and the other telescopic limiting nut can be arranged at one side of the telescopic limiting hole for fixing the telescopic limiting screw 511, and one end of the telescopic limiting screw 511 supports against the inner side of the sweeping disk rotating shaft connecting piece after rotating around the sweeping disk rotating shaft 524 for a certain angle along with the sweeping disk rotating shaft connecting sleeve 523. Preferably, the telescopic limiting hole may be provided with an internal thread, and the telescopic limiting screw 511 may be provided with an external thread, in which case the telescopic limiting screw 511 is provided with one. When the sweeping disk telescopic device 51 drives the sweeping disk rotating shaft connecting sleeve 523 to rotate clockwise around the sweeping disk rotating shaft 524, the telescopic limiting screw 511 on the sweeping disk rotating shaft connecting sleeve 523 rotates along with the sweeping disk rotating shaft until one end of the telescopic limiting screw 511 abuts against the sweeping disk rotating shaft fixing piece 522, the sweeping disk rotating shaft 524 is clamped, the sweeping disk rotating shaft connecting sleeve 523 cannot rotate continuously around the sweeping disk rotating shaft 524, and therefore the extending position of the sweeping disk rotating shaft connecting sleeve 523 is limited. Therefore, the extension position of the connecting sleeve 523 of the sweeping disk rotating shaft can be adjusted by controlling the length of the telescopic limit screw 511 protruding out of the sweeping disk rotating shaft 524, the shorter the length of the telescopic limit screw 511 protruding out of the sweeping disk rotating shaft 524 is, the larger the extension range of the connecting sleeve 523 of the sweeping disk rotating shaft is, and similarly, the longer the length of the telescopic limit screw 511 protruding out of the sweeping disk rotating shaft 524 is, the smaller the extension range of the connecting sleeve 523 of the sweeping disk rotating shaft is.

As a preferred embodiment, in order to facilitate the limiting of the telescopic limiting screw 511, a telescopic limiting block 5221 may be further disposed inside the sweeping disk rotating shaft fixing member 522, the telescopic limiting block 5221 protrudes toward the sweeping disk rotating shaft 524, and one end of the telescopic limiting screw 511 rotates around the sweeping disk rotating shaft 524 for a certain angle along with the sweeping disk rotating shaft connecting sleeve 523 and then abuts against the telescopic limiting block 5221. When the sweeping disk telescopic device 51 drives the sweeping disk rotating shaft connecting sleeve 523 to rotate clockwise around the sweeping disk rotating shaft 524, the telescopic limiting screw 511 on the sweeping disk rotating shaft connecting sleeve 523 rotates along with the sweeping disk rotating shaft until one end of the telescopic limiting screw 511 abuts against the telescopic limiting block 5221, the sweeping disk rotating shaft 524 is clamped, the sweeping disk rotating shaft connecting sleeve 523 cannot rotate continuously around the sweeping disk rotating shaft 524, and therefore the extending position of the sweeping disk rotating shaft connecting sleeve 523 is limited. Therefore, the extension position of the connecting sleeve 523 of the rotating shaft of the sweeping disc can be adjusted by controlling the length of the telescopic limit screw 511 protruding out of the telescopic limit block 5221, the shorter the length of the telescopic limit screw 511 protruding out of the telescopic limit block 5221 is, the larger the extension range of the connecting sleeve 523 of the rotating shaft of the sweeping disc is, and similarly, the longer the length of the telescopic limit screw 511 protruding out of the telescopic limit block 5221 is, the smaller the extension range of the connecting sleeve 523 of the rotating shaft of the sweeping disc is.

According to some embodiments of the present application, optionally, as shown in fig. 5, the sweeping disk assembly 52 further comprises a sweeping disk lifting device 521, a sweeping disk 526, and a sweeping disk swing arm connection 525, the sweeping disk 526 comprising a sweeping disk 5261. One end of the sweeping disc lifting device 521 is fixed at the upper end of the sweeping disc rotating shaft connecting sleeve 523, and the other end of the sweeping disc lifting device 521 is connected with the sweeping disc piece 526.

The pan assembly 526 includes a pan 5261, a pan motor, and a pan motor mount on which the pan motor is mounted. The cleaning pan motor is used for driving the cleaning pan 5261 to rotate, so that the cleaning pan 5261 performs cleaning operation.

Two ends of the sweeping disk swing arm connecting piece 525 can be respectively connected with the sweeping disk rotating shaft connecting sleeve 523 and the sweeping disk motor seat of the sweeping disk piece 526 through pin shafts, and the sweeping disk rotating shaft connecting sleeve 523 is connected with the sweeping disk piece 526 through the sweeping disk swing arm connecting piece 525. Thus, when the sweeping disk telescopic device 51 drives the sweeping disk rotating shaft connecting sleeve 523 to rotate clockwise or counterclockwise around the sweeping disk rotating shaft 524, the sweeping disk 5261 on the sweeping disk member 526 extends outwards or retracts inwards.

One end of the sweeping disc lifting device 521 is fixed at the upper end of the sweeping disc rotating shaft connecting sleeve 523, and the other end of the sweeping disc lifting device 521 can be connected to a sweeping disc motor seat of the sweeping disc member 526 through a Y-shaped joint. The sweeping disk lifting device 521 can be an air cylinder or an oil cylinder, and the piston rod stretches and retracts to drive the sweeping disk member 526 to move upwards or downwards around a pin shaft connected with the sweeping disk swing arm connecting member 525 and the sweeping disk rotating shaft connecting sleeve 523, that is, to drive the sweeping disk 5261 on the sweeping disk member 526 to ascend or descend relative to the ground. When the sweeping disk lifting device 521 drives the sweeping disk 526 to move upwards around a pin shaft connected with the sweeping disk swing arm connecting piece 525 and the sweeping disk rotating shaft connecting sleeve 523, the sweeping disk 5261 rises relative to the ground; when the sweeping disk lifting device 521 drives the sweeping disk 526 to move downwards around the pin shaft connected with the sweeping disk rotating shaft connecting sleeve 523 and the sweeping disk swing arm connecting piece 525, the sweeping disk 5261 descends relative to the ground.

According to some embodiments of the present application, optionally, as shown in fig. 6, a lifting limit hole is provided below the connecting sleeve 523 of the sweeping disk rotating shaft, and a lifting limit nut 529 is provided at the lifting limit hole. The lifting limit screw 528 passes through the lifting limit nut 529 and the lifting limit hole, and the telescopic limit screw 511 is used for adjusting the descending height of the sweeping disc 5261 relative to the ground by adjusting the length of the convex sweeping disc swing arm connecting piece 525.

In order to limit the height of the cleaning disc 5261 from the ground and prevent the cleaning disc 5261 from being excessively lowered from the ground to damage bristles of the cleaning disc 5261, a lift-limiting screw 528 and a lift-limiting nut 529 are provided. The lower end of the sweeping disc connecting sleeve is provided with a lifting limiting hole, the lifting limiting nut 529 is fixed at the lifting limiting hole, one lifting limiting hole can be arranged on each of the two sides of the lifting limiting hole, and one lifting limiting hole can be arranged on one side of the lifting limiting hole for fixing a lifting limiting screw 528. Preferably, the lift stop hole may be internally threaded and the lift stop screw 528 may be externally threaded, in which case one lift stop screw 528 is provided. When the sweeping disk lifting device 521 drives the sweeping disk 526 to move downwards around the pin shaft connected with the sweeping disk swing arm connecting piece 525 and the sweeping disk rotating shaft connecting sleeve 523, the sweeping disk swing arm connecting piece 525 can also move downwards along with the downward movement until the telescopic limit screw 511 abuts against the lower surface of the sweeping disk swing arm connecting piece 525, the sweeping disk swing arm connecting piece 525 is clamped, the sweeping disk lifting device 521 cannot drive the sweeping disk 526 to continuously move downwards, the descending height of the sweeping disk 5261 on the sweeping disk 526 is limited, and the phenomenon that the sweeping disk 5261 is too low to lift off the ground to damage bristles of the sweeping disk 5261 is avoided. Therefore, the descending height of the sweeping tray 5261 can be adjusted by controlling the length of the lifting limit screw 528 protruding out of the sweeping tray swing arm connecting member 525, and the lower the length of the lifting limit screw 528 protruding out of the sweeping tray swing arm connecting member 525, the lower the descending height of the sweeping tray 5261, i.e. the lower the height from the ground. Similarly, the longer the lifting limit screw 528 protrudes from the sweeping tray swing arm connector 525, the higher the descending height of the sweeping tray 5261, i.e. the height above the ground.

As a preferred embodiment, in order to facilitate the lifting of the limit screw 528 for limiting, a lifting limit block 527 may be further disposed on the lower surface of the sweeping tray swing arm connecting member 525, and the lifting limit block 527 may be disposed to be inclined downward by a certain angle or may be disposed to vertically sweep the sweeping tray swing arm connecting member 525. When the sweeping disc lifting device 521 drives the sweeping disc 526 to move downwards around a pin shaft connected with the sweeping disc swing arm connecting piece 525 and the sweeping disc rotating shaft connecting sleeve 523, the sweeping disc swing arm connecting piece 525 can also move downwards along with the downward movement, the lifting limiting block 527 on the sweeping disc swing arm connecting piece 525 can also move downwards along with the downward movement, until the telescopic limiting screw 511 abuts against the lifting limiting block 527, the sweeping disc swing arm connecting piece 525 is clamped, and the sweeping disc lifting device 521 cannot drive the sweeping disc 526 to continue to move downwards.

Swing arm connecting sleeves 475 are fixed on two sides of the rolling brush casing 471, and swing arm connecting holes are formed in the swing arm connecting sleeves 475. One end of the swing arm connecting shaft 476 is arranged on the swing arm member 472, the other end of the swing arm connecting shaft 476 penetrates through the swing arm connecting hole, and the swing arm connecting shaft 476 is sequentially sleeved with an elastic member 477 and a rolling brush adjusting nut 478 above the swing arm connecting sleeve 475. The roller adjusting nut 478 adjusts the elastic force of the elastic member 477 for adjusting the height of the roller brush 474.

Wherein, swing arm connecting axle 476 is the screw thread of taking the scale, and elastic component 477 is compression spring, and round brush adjusting nut 478 is double nut. Swing connecting sleeves are fixed at two ends of the rolling brush casing 471, and a swing arm connecting shaft 476 is connected with the swing arm member 472 through a ball joint and penetrates through the swing connecting sleeves. The compression spring is sleeved on the swing arm connecting shaft 476 and clamped between the double nuts and the swing connecting sleeve and used for controlling the descending amplitude of the rolling brush 474, the rolling brush device 4 needs to be debugged before the road cleaning equipment is used, air is discharged through an A port of an air cylinder of the suction lifting device 39 in the debugging process, the rolling brush 474 is in a free landing state around a rotating shaft under the action of gravity due to the rolling brush 474 and a component for installing the rolling brush 474, and most of the length of the brush of the rolling brush 474 is pressed, deformed and bent to be attached to the ground due to the gravity of the rolling brush 474 and the component for installing the rolling brush 474. When the double nuts are continuously adjusted downwards, the rolling brushes 474 can be subjected to the outward acting force of the compression spring, the double nuts are continuously adjusted downwards until the compression spring is compressed to a certain degree, the spring force is greater than the downward acting force of the rolling brushes 474 and the installation rolling brushes 474, the rolling brushes 474 rise around the rotating shaft in order to find a new balance point under the action of the spring force, and at the moment, the acting force of the rolling brushes 474 on the ground is reduced. When the amount of addiction between the brush of the roller brush 474 and the ground is 5mm, the adjustment of the double nuts is stopped, at which time the spring force is approximately equal to the weight of the roller brush 474 and the attachment minus the force of the roller brush 474 on the ground to reach a point of equilibrium.

In practical use, when the road sweeping device is not needed, the piston rods of the sweeping disc extending devices 51 distributed on the two sides of the chassis are in a contracted state, and the piston rods of the sweeping disc lifting devices 521 are also in a contracted state, so that the whole sweeping disc 5261 is located at the two ends of the chassis and does not exceed the width of a vehicle to be used. The suction lifting device 39 on the suction device 3 is also in a contracted state, so that the suction device 3 is hung on the chassis frame 1, and two sides of the suction device 3 are ensured not to exceed the vehicle width. Because the suction device 3 and the sweeping disc device 5 are both in an upward lifting state, and because the first sweeping disc baffle 531 is fixed on the sweeping disc swing arm connecting piece 525, and the second sweeping disc baffle 532 is arranged on the suction bracket 31 of the suction device 3, when the suction device 3 and the sweeping disc device 5 are lifted up, the first sweeping disc baffle 531 and the second sweeping disc baffle 532 are lifted up, the friction between the first sweeping disc baffle 531 and the second sweeping disc baffle 532 and the ground is avoided when the vehicle is driven at high speed in a transition, and the service life of the vehicle is prolonged. The roll brush lifting device 45 is also in a retracted state for the roll brush unit 4, in which case the roll brushes 474 are lifted away from the floor.

When the road cleaning equipment is required to be used for deeply cleaning the road surface, the piston rod of the sweeping tray telescopic device 51 extends out, the piston rod of the sweeping tray lifting device 521 also extends out, the sweeping tray 5261 extends out of the vehicle and descends, the brush of the sweeping tray 5261 is in contact with the ground, and the first sweeping tray baffle 531 on the sweeping tray assembly 52 is in contact with the ground. After the piston rod of the suction lifting device 39 of the suction device 3 extends, the suction device 3 contacts with the ground, the second sweeping disk baffle 532 is hung on the suction device 3, when the suction device 3 falls to the ground, the second sweeping disk baffle 532 contacts with the ground, and the rolling brush 474 on the rolling brush device 4 enables the rolling brush 474 to fall to the ground due to the gravity of the rolling brush device and the extension of the piston rod of the rolling brush lifting device 45.

When the sweeping tray 5261, the rolling brushes 474 and the suction device 3 fall on the ground, the sweeping tray motor on the sweeping tray 5261 and the rolling brush motor 473 on the rolling brushes 474 start to rotate, the on-board fan starts, and the suction device 3 starts to suck with high negative pressure. When the vehicle runs in operation, the suction spray rod device 36 and the rolling brush spray rod device 49 are opened, high-pressure water jet starts to wash the road surface at high pressure through the fan-shaped nozzles, the washing and sweeping operation starts, the rolling brush device 4 can be controlled to incline leftwards or rightwards through the swinging device 44 according to the road condition, when dirt such as garbage is pushed to the front of the suction device 3 on the right side, the suction device 3 on the right side performs powerful suction, and a piston rod of the swinging device 44 contracts.

In the operation process of the whole vehicle, all the washed and swept stains can be driven towards two sides, and are sucked into the garbage can of the vehicle through the suction devices 3 on the two sides. Therefore, the suction lance 36 operates in cooperation with the left and right sweeping plates 5261, and when the sweeping plates 5261 sweep the dust on the road surface and hardened dust, the suction lance 36 performs strong water pressure washing to flush the sewage and soil to the front of the suction device 3, and the first sweeping plate baffle 531 and the second sweeping plate baffle 532 beside the sweeping plate 5261 guide the flow, so that the washed and swept garbage and soil are guided to the front end of the suction device 3, and the suction device 3 performs strong suction and prevents the soil from splashing. When the suction device 3 needs to suck other large garbage such as mineral water bottles, beverage bottles and the like in the washing and sweeping process, the piston rod of the suction opening-closing device 33 extends out, the height of the suction opening from the ground becomes high, and after the large garbage is sucked in, the piston rod of the suction opening-closing device 33 contracts to retract the height of the suction opening from the ground to restore and continue working. After the work is finished, the whole vehicle returns to the transition state.

When the road cleaning equipment is required to clean and clean the road surface, the piston rod of the sweeping tray telescopic device 51 extends out, the piston rod of the sweeping tray lifting device 521 also extends out, the sweeping tray 5261 extends out of the vehicle and descends, the brush of the sweeping tray 5261 is in contact with the ground, and the first sweeping tray baffle 531 on the sweeping tray assembly 52 is in contact with the ground. After the piston rod of the suction lifting device 39 of the suction device 3 extends, the suction device 3 is contacted with the ground, and because the second sweeping disc baffle 532 is hung on the suction device 3, when the suction device 3 falls to the ground, the second sweeping disc baffle 532 is contacted with the ground; the roller brush 474 on the roller brush device 4 causes the roller brush 474 to fall to the floor due to its own weight and as the piston rod of the roller brush lifting device 45 extends. When the sweeping disc 5261, the rolling brush 474 and the suction device 3 fall on the ground, the sweeping disc motor on the sweeping disc 5261 and the rolling brush motor 473 on the rolling brush 474 start to rotate, the fan on the vehicle starts, the suction device 3 starts high negative pressure suction, and meanwhile, the suction dust removal device 37, the rolling brush dust removal device 48 and the sweeping disc dust removal device 54 are opened, the fan-shaped dust removal nozzles on the dust removal spray rods start spraying, and the dust removal device is arranged beside the sweeping disc 5261, so that certain dust can be generated when the sweeping disc 5261 cleans a road, and the dust needs to be killed at the source in order to avoid the dust diffusion. Set up dust collector at the suction mouth because its suction in-process is because negative pressure does the suction speed big, if does not have the spot dust that will suck here to come in moist, then can have dust in the fan export and smoke out, can cause secondary air pollution, when the operation back that finishes, whole car gets back to the state of transition.
