DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] See also Figure 1-3The utility model provides a technical solution: a road sweeper with a self-unloading function, the road sweeper body includes a frame 1, a box 2, and a scraper 13, the box 2 is rotatably arranged on the frame 1, a lifting rod 14 is arranged on the frame 1, the box 2 is rotatably connected to the top of the lifting rod 14, the scraper 13 is slidably arranged inside the box 2 along the length direction, the inner cavity of the box 2 is provided with a driving component for driving the scraper 13 to slide left and right, and the top of the inner wall of the box 2 is provided with a water spray head 16 that can spray water to both sides of the box 2.

[0019] In this embodiment, the function of the water spray head 16 is to clean the residual garbage and stains on the inner wall of the box body 2 by spraying water during the cleaning process or after dumping the garbage, so as to keep the box body 2 clean and sanitary.

[0020] When it is necessary to dump the garbage in the box 2, the operator manually adjusts the height of the lifting rod 14 to place the box 2 in a suitable dumping position. During the dumping, the operator manually drives the scraper 13 to completely remove the garbage from the inside of the box 2. Then the operator manually starts the water spray head 16 to spray water on both sides of the box 2 to ensure the cleanliness of the inner wall of the box 2. After dumping the garbage, the operator can close the water spray head 16 and return the box 2 to its original position to continue the cleaning operation.

[0021] Furthermore, the driving assembly includes an installation box 4, each of which is fixedly connected to the left and right sides of the top inner wall of the box body 2, and a screw rod 5 is rotatably arranged in each of the installation boxes 4. The surface of each screw rod 5 is threadedly connected with a threaded sleeve 6, and the surfaces of two threaded sleeves 6 are fixedly connected with push plates 7, and the scraper 13 is fixedly connected to the surface of the push plate 7. The outside of the box body 2 is fixedly connected with a motor 8, and the output shaft of the motor 8 passes through the inside of the box body 2 and is fixedly connected to one of the screw rods 5.

[0022] In this embodiment, a groove matching with the push plate 7 is opened on the inner wall of the left side of the box body 2 to ensure that the push plate 7 can be stored on the inner wall of the box body 2 and the scraper 13 is at the innermost part of the box body 2 to avoid occupying the internal space of the box body 2.

[0023] In order to ensure that the two screw rods 5 can rotate synchronously, a belt is used to connect the two screw rods 5. When one of the screw rods 5 is driven to rotate by the motor 8, the other screw rod 5 will also rotate synchronously through the transmission of the belt.

[0024] When the motor 8 is started, it drives the screw rod 5 connected to it to rotate, and the other screw rod 5 will also rotate synchronously through the transmission of the pulley 15. As the screw rod 5 rotates, the threaded sleeve 6 moves along the length direction of the screw rod 5, thereby driving the push plate 7 and the scraper 13 to move. In this way, the scraper 13 can move accurately inside the box 2 and push the garbage to the outside of the box 2.

[0025] Furthermore, a water storage barrel 11 is provided on the frame 1, and a water pump 10 is fixedly connected to the top of the water storage barrel 11. The water inlet of the water pump 10 is connected to a water inlet pipe for supplying water to the inner cavity of the water storage barrel 11. The water outlet of the water pump 10 is detachably provided with a water outlet pipe 9, and the other end of the water outlet pipe 9 is connected to a water spray head 16. A receiving box 12 is provided in the middle of the inner wall of the box body 2, and the water spray head 16 is arranged in the inner cavity of the receiving box 12. A plurality of water spray holes are opened at the bottom of the receiving box 12.

[0026] In this embodiment, a plurality of water spray holes are opened at the bottom of the receiving box 12, and the water spray head 16 is placed in the receiving box 12 to ensure that garbage will not block the water spray head 16 and ensure that water is sprayed toward the side wall of the box body 2 all the time.

[0027] The receiving box 12 is located at the top and in the middle of the box body 2 , ensuring that the water spray head 16 can clean the side wall of the box body 2 .

[0028] When the water pump 10 is started, water is pumped out from the water storage barrel 11, flows to the water spray head 16 through the water outlet pipe 9, and then sprayed out through the water spray holes at the bottom of the receiving box 12 to wash the side walls of the box body 2.

[0029] Furthermore, a compartment cover 3 is rotatably provided at the rear end of the box body 2 .

[0030] In this embodiment, the compartment cover 3 is connected to the rear end of the box body 2 by a hinge or other rotatable connecting part so that it can rotate around a fixed point. This design allows the operator to open or close the compartment cover 3 as needed. When it is necessary to put garbage into the box body 2 or to clean it, the operator can easily open the compartment cover 3 to expose the interior of the box body 2. When the sweeper is driving normally or there is no need to open the box body 2, the compartment cover 3 remains closed to prevent garbage from being scattered or external debris from entering the box body 2.

[0031] Furthermore, two groups of sweepers 17 are arranged below the frame 1 .

[0032] In this embodiment, when the road sweeper starts to travel, the two sets of sweepers 17 will start and contact the ground to start cleaning the road. The rotation or movement of the sweepers 17 can sweep the garbage and debris on the road to the center area of ​​the vehicle, which is then collected by the scraper 13 and sent into the box 2.

[0033] The working principle and use process of the utility model: After the utility model is installed, the road sweeper is first parked at the place where garbage needs to be dumped, and then the compartment cover 3 is opened manually, and then the lifting rod 14 is started to separate the box body 2 and the frame 1. After reaching a certain inclination angle, the motor 8 is turned on to drive the screw rod 5 to rotate, connected through the pulley 15, and the other screw rod 5 rotates together, and then drives the threaded sleeve 6 to slide, thereby driving the push plate 7 on the surface of the threaded sleeve 6 to move the scraper 13 along the box body 2, and spray water into the box body 2 through the water spray head 16 for further cleaning.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
