The collusion connection between the double-roller cleaning mechanism of the sweeper and the roller brush garbage conveying system can be set as:

1. When the top of the rear sweeping cover of the cleaning mechanism is provided with a rear sweeping garbage outlet, the roller brush garbage conveying system is provided with a garbage conveying inlet at the lower end of the first-stage roller brush cover. At this time, the rear roller sweeping garbage outlet and the roller brush The lower end of the first-stage rolling brush cover of the garbage conveying system is provided with a garbage conveying inlet collusion connection (as shown in Figure 4).

2. When the sweeping mechanism is provided with a rear rolling sweep garbage outlet on the other semicircular upper part of the rear rolling sweep covering adjacent to the front rolling sweep covering, which is biased towards the side of the garbage bin (the second quadrant position of the rear rolling sweep covering) , the garbage inlet of the first-stage rolling brush cover of the rolling brush garbage conveying system is set at the fourth quadrant of the rolling brush covering. Set as an active connection or a soft connection (as shown in Figure 2 and Figure 3).

Advantages of the present invention:

The invention has the advantages of simple structure and low cost, can clean large and small garbage, and can clean up uneven ground. Since the cleaning system is set as a double-roller cleaning mechanism, the elastic dust guide plate at the lower part of the front rolling-sweeping cover of the double-rolling-sweeping cleaning mechanism can be set at a certain distance from the ground, allowing larger garbage to pass through the lower part of the front rolling-sweeping cover first. The elastic dust guide plate is swept by the front roller for the first cleaning, and then the rear roller sweeps the garbage missed by the front roller sweep for the second cleaning, which has a higher degree of cleanliness. If the roller brush conveying system is installed, the double-roller cleaning mechanism and the roller brush conveying system can be set as independent structures, so that the roller brush conveying system can be fixed on the frame, and the garbage inlet of the roller brush conveying system and the double roller The sweeping garbage outlet of the sweeping mechanism is a soft connection (movable connection up and down). Because the rotation directions of the front rolling sweep and the rear rolling sweep of the present invention are all rotating in the direction opposite to the driving direction, the whole mechanism of the present invention is in the process of driving forward, and the front rolling sweep and the rear rolling sweep are constantly opposite to the traveling direction. Rotate in the same direction, so that the garbage enters the continuously rotating front and rear rolling sweeps, and finally enters the garbage bin. Therefore, the front and rear rolling sweeps of the present invention can move up and down more freely with the unevenness of the ground, which not only improves the cleanliness, The energy consumption is reduced, the wear of the brush can be reduced, the damage of the roller sweep can be reduced, and the service life of the roller sweep can be prolonged. Hanging tension spring and chain, the lifting force of the spring can reduce and buffer the pressure between the roller sweep and the ground, which can further improve the flexibility of the roller sweep to move up and down with the unevenness of the ground, and can further reduce the wear and tear of the brush Damage to support rollers. When the operation is stopped, the double-roller cleaning mechanism only needs to be lifted, and the roller brush conveying system does not need to be lifted, so the lifting mechanism is simpler and more energy-saving. Like this, compared with the cleaning mechanism of existing pure-sweeping type road sweeping vehicle, avoidance effect is better, compared with the cleaning mechanism of existing suction-sweeping type road sweeping vehicle, it is more energy-saving and environment-friendly.
