Description

Technical Field

[0001] The utility model relates to the technical field of sweepers, in particular to a sweeper with a side brush anti-collision structure. Background Art

[0002] The sweeper is an integrated garbage sweeper that combines sweeping and vacuuming. Two rotating brushes are installed at the front of the vehicle. When the vehicle moves forward, the aforementioned brushes will bring the garbage and sand on the ground to the middle of the vehicle through rotation, and then use the vehicle's vacuum suction head to suck the garbage and sand into the waste collection box on the vehicle. When the vehicle moves forward, the rotating brush at the front of the vehicle will inevitably collide with other objects, and anti-collision components are usually installed on the side brushes to prevent damage to the side brushes.

[0003] The patent specification with announcement number CN218643284U discloses an electric sweeper, including a body; a dust hood with an opening facing downward is installed at the bottom of the body, and the dust hood includes a dust collecting hood placed on the front side and a dust shielding hood placed on the rear side; the left and right ends of the dust hood are extended outward to enlarge the inner cavity of the dust hood, and two side brush mechanisms are installed in the dust hood, and the two side brush mechanisms are respectively placed at the left and right ends of the inner cavity of the dust hood; a roller brush mechanism is installed in the dust shielding hood, and the bottom edges of the left and right ends of the dust shielding hood are installed with rubber strips for contacting the ground; the lower end of the dust suction pipe extends into the dust shielding hood, and the lower end of the dust suction pipe is placed on the rear side of the roller brush mechanism for sucking away dust in the dust shielding hood; the dust hood is installed at the bottom of the body to cover the lower side of the body, and at the same time cover the side brush mechanism and the roller brush mechanism to avoid dust diffusion and improve the cleaning effect of the electric sweeper.

[0004] However, in the implementation of relevant technologies, it was found that an electric sweeper of the above-mentioned design has the following problems: since the size of the dust hood is fixed, the deployment range of the side brush is limited, and the side brush is covered inside the dust hood. During the movement of the electric sweeper, the dust hood will inevitably collide with other objects. Once the dust hood is damaged, the dust shielding effect will be reduced. In view of this, a sweeper with a side brush anti-collision structure is provided to overcome the above-mentioned defects. Utility Model Content

Dust can be reduced by water mist instead of dust cover, and the spray head 17 on the connecting head 9 is in the same position as the movable side brush 5. When the movable side brush 5 extends outward, the spray head 17 on the connecting head 9 also moves accordingly, and will not limit the movement of the movable side brush 5.

[0024] As a further implementation scheme of the above technical scheme: a bidirectional screw rod 14 is installed inside the movable sleeve 8 through a screw nut, and a driven gear 13 is fixedly sleeved on the surface of the bidirectional screw rod 14. The bidirectional screw rod 14 can drive the movable sleeve 8 to move in opposite directions on both sides, thereby adjusting the distance between the two sets of movable side brushes 5, making it convenient to deploy the movable side brushes 5 and increasing the cleaning range.

[0025] As a further implementation scheme of the above technical scheme: one side of the driven gear 13 is meshedly connected with a driving gear 16, and the upper part of the driving gear 16 is connected with the power output end of the servo motor 15, and the outside of the servo motor 15 is provided with a fixing box 7 fixed in the middle of the bottom of the vehicle body 1, and the servo motor 15 drives the driving gear 16 to rotate through the power output end, thereby driving the driven gear 13 to rotate through the driving gear 16.

[0029] As a further implementation scheme of the above technical scheme: a water pump is installed at the connection between the rigid connecting pipe 10 and the water storage tank 2, and the water pump can pump out the water in the water storage tank 2 and supply it to the spray head 17 through the rigid connecting pipe 10.

[0030] During specific implementation, when the movable side brush 5 moves to both sides, the telescopic tube 12 is extended and retracted as the position of the movable side brush 5 changes. After the water pump is started, the water in the water tank 2 is transmitted to the spray head 17 under the support plate 6 through the rigid connecting tube 10. The rigid connecting tube 10 is fixedly connected to the fixed box 7 to support the rigid connecting tube 10, while the water in the other two groups of rigid connecting tubes 10 is sprayed out by the spray head 17 under the connecting head 9 through the telescopic tube 12, so that water can be sprayed on the ground, increasing the air humidity to prevent dust from being raised, and using water mist to reduce dust instead of using a dust cover to cover dust. Since the spray head 17 on the connecting head 9 also moves when the movable side brush 5 extends outward, the movement of the movable side brush 5 will not be restricted.
