Description

Technical Field

[0001] The utility model relates to the technical field of sweepers, in particular to a rolling brush device for a small sweeper. Background Art

[0002] With the development of social economy and the improvement of urban level, the population is becoming more and more concentrated, and the corresponding requirements for environmental sanitation are getting higher and higher. It is easy to accumulate garbage and dust on the urban road surface, which needs to be dealt with in time, otherwise it will not only affect the appearance of the city, but also affect people's healthy travel. Roller sweeper is a kind of sweeper, which is mainly used for special vehicles for urban appearance arrangement and cleaning. Roller sweeper uses a disc brush to concentrate garbage of a certain width to the middle position of the vehicle, and then sweeps the garbage into the garbage bin through the roller brush to achieve road cleaning. During the operation of the roller sweeper, the garbage is thrown into the garbage bin behind the brush under the rotation of the bristles, so as to achieve the cleaning and collection of road garbage. There is a large space on both sides of the roller brush in the existing technology. The first disadvantage is that when the sweeper encounters small and dense garbage such as soil and stones during operation, due to the large space between the jaw plate and the roller brush, the roller brush cannot be rotated to throw such garbage into the garbage collection box. There is a high probability that such garbage will remain in this area and move forward with the vehicle. When the cleaning task is completed and the roller brush stops working, such garbage will be left on the road, affecting the cleaning quality of the sweeper. Disadvantage 2: During the operation of the sweeper, the garbage passes through the jaw plate, over the roller brush, and is thrown into the garbage collection box. When the garbage in the garbage box slowly accumulates to a height that exceeds the height of the front opening of the garbage box, the roller brush rotates, driving the air around the roller brush to rotate. A negative pressure area is formed at the entrance of the garbage box and between the roller brush and the rear rubber guard of the roller brush. At this time, lighter garbage near the entrance of the garbage collection box, such as dry leaves and paper towels, may be carried by the airflow between the roller brush and the rear rubber guard of the roller brush. Since the vehicle moves forward at the same time, the garbage at this position will be missed with a high probability, resulting in incomplete cleaning. Utility Model Content

At the same time, the garbage collection box 6 is connected to a fan, and the fan is set to suck in when the roller brush 21 collects garbage, thereby improving the cleaning effect and reducing garbage omission.

[0052] Specific working process: When the sweeper performs the cleaning task, when there is less garbage on the road, such as small leaves, fine sand and gravel, the jaw plate 31 is located in the first working position (such as Figure 2 As shown), at this time, the lower edge of the jaw plate 31 is about 2mm from the ground. During the operation, under the guarantee of the built-in sensor, the driving member 32 extends 40mm and stops, and the garbage enters the scattering area of ​​the roller brush assembly 2 through the jaw plate assembly 3. The roller brush 21 rotates to scatter the garbage upward, and guides the garbage into the garbage collection box 6 through the transportation channel 61. After the garbage collection box 6 accumulates a certain amount of garbage, due to the rotation of the roller brush assembly 2, some lightweight garbage near the entrance of the garbage collection box 6 has a chance to fall back to the rear of the roller brush 21. At this time, since the garbage rear block assembly extends below the roller brush 21, the fallen garbage is guided to the bottom of the roller brush assembly 2 and is thrown back into the garbage collection box 6 under the rotation of the roller brush assembly 2. When there is a lot of garbage on the road and the volume is large, in order to ensure that the garbage effectively enters the cleaning area of ​​the roller brush assembly 2, the jaw plate 31 lifts the electric push rod and is completely retracted. Under the action of the connecting rod assembly, the jaw plate 31 is fully opened and is in the second working position (as shown in the figure). Figure 4 When the current road cleaning is completed and the cleaning task is ready to end, the drive member 32 is fully extended, and the jaw assembly 3 is in the third working position (as shown in FIG. Figure 5 As shown in the figure, the gap between the jaw plate assembly 3 and the roller brush assembly 2 is reduced. In this state, the small-volume and high-density garbage can be effectively cleaned. The jaw plate assembly 3 extends below the roller brush assembly 2, which can more effectively catch the high-density garbage thrown by the roller brush assembly 2, thereby realizing the collection of the last 1 meter of garbage.

[0053] For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all fall within the protection scope of the utility model.
