Description

Technical Field

[0001] This utility model is an automatic road sweeper with a solid-liquid separation device, belonging to the field of road sweeping technology. Background Technology

[0002] Automated road sweepers are key equipment for urban environmental sanitation. They achieve unmanned cleaning through an autonomous driving system (GPS + visual recognition) and are widely used in municipal roads, squares, parks, and other scenarios. The core requirements are efficient garbage collection (sweeping efficiency ≥90%), reduced human intervention, and lower subsequent garbage disposal costs. Road garbage often exists in a "solid-liquid mixture" form (such as mud and sewage from rainy days, fallen leaves and stagnant water, fruit peels and beverage stains, etc.).

[0003] However, existing sweepers lack dedicated solid-liquid separation devices, resulting in "mud-like" garbage after collection, leading to low utilization of garbage storage bin volume; and liquid is prone to leakage and road pollution during transportation. There is an urgent need for an automated road sweeper with a solid-liquid separation device to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an automated road sweeper with a solid-liquid separation device to solve the problems mentioned in the background. This invention employs a waste collection and hydraulic structure, which can collect, compress, and perform multiple solid-liquid separations on road waste that is mixed with solids, thereby achieving effective separation of liquids, solid particles, and solid waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic road sweeper with a solid-liquid separation device, comprising a garbage collection bin, a door mounted on the front end of the garbage collection bin via multiple hinges, a hydraulic rod mounted on the upper end of the garbage collection bin, a pressure plate mounted on the movable end of the hydraulic rod, and the pressure plate being horizontally located at the upper end of the inside of the garbage collection bin, a garbage inlet opening on the upper right side of the garbage collection bin, and two bending seats mounted on the right end of the garbage collection bin via multiple bolts, a drive shaft mounted between the two bending seats, and metal strips welded to the front and rear sides of the lower end of the drive shaft. A garbage collection hopper is welded to the lower end of the metal strip. Casters are installed on the front and rear sides of the lower left side of the garbage collection hopper. A servo motor is installed at the rear end of the bending seat. A first support frame and a second support frame are installed inside the garbage collection box via multiple bolts. A first filter screen and a second filter screen are respectively held on the upper ends of the first and second support frames. An electric telescopic rod is embedded at the rear end of the garbage collection box. A garbage pusher plate is installed at the movable end of the electric telescopic rod. An inclined guide plate is fixed to the lower end of the inside of the garbage collection box, and a liquid baffle is fixed to the front end of the inclined guide plate. A drain valve is embedded at the front end of the liquid baffle.

[0006] Furthermore, the lower end of the waste collection bin is equipped with multiple drive wheels, and the upper right side of the waste collection bin is equipped with a processing module, a vision recognition module, and a GPS module. The processing module has a built-in microcontroller and a battery, and the microcontroller is connected to the multiple drive wheels, the vision recognition module, the GPS module, and the battery through wires.

[0007] Furthermore, the GPS module is connected to an external terminal via GPS signals, and the visual recognition module is a multi-algorithm camera.

[0008] Furthermore, the servo motor shaft is connected to the transmission shaft.

[0009] Furthermore, sweeping motors are installed at the front and rear positions of the lower right side of the garbage collection box, and sweeping brushes are installed at the lower ends of the two sweeping motors.

[0010] Furthermore, the waste pusher is located above and behind the first filter screen.

[0011] The beneficial effects of this utility model are as follows: This utility model provides an automatic road sweeper with a solid-liquid separation device. Because this utility model adds a hydraulic rod, pressure plate, bending seat, servo motor, metal strip plate, moving wheel, garbage collection bucket, garbage pusher, electric telescopic rod, first support frame, first filter screen, second support frame, second filter screen, and liquid baffle, the structure is reasonable. It adopts a garbage collection and hydraulic structure, which can collect, compress, and perform multiple solid-liquid separation of road garbage mixed with solids and liquids, thereby achieving effective separation of liquid, solid particles, and solid garbage.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3This utility model provides a technical solution: an automatic road sweeper with a solid-liquid separation device, including a garbage collection box 1. A box door 2 is installed at the front end of the garbage collection box 1 via multiple hinges. A hydraulic rod 6 is installed at the upper end of the garbage collection box 1, and a pressure plate 7 is installed at the movable end of the hydraulic rod 6. The pressure plate 7 is horizontally located at the upper end of the inside of the garbage collection box 1. A garbage inlet 8 is opened on the upper right side of the garbage collection box 1. Two bending seats 9 are installed on the right end of the garbage collection box 1 via multiple bolts. A drive shaft is installed between the two bending seats 9, and metal strips 11 are welded to the front and rear sides of the lower end of the drive shaft. A garbage collection hopper 13 is welded to the lower end of the two metal strips 11. Moving wheels 12 are installed at the front and rear positions of the lower left side of the garbage collection hopper 13. The rear bending seat 9... A servo motor 10 is installed at the rear end. Inside the garbage collection bin 1, a first support frame 18 and a second support frame 20 are installed by multiple bolts. A first filter screen 19 and a second filter screen 21 are respectively clipped onto the upper ends of the first support frame 18 and the second support frame 20. An electric telescopic rod 17 is embedded at the rear end of the garbage collection bin 1. A garbage pusher plate 16 is installed at the movable end of the electric telescopic rod 17. An inclined guide plate is fixed at the lower end of the inside of the garbage collection bin 1, and a liquid baffle 22 is fixed at the front end of the inclined guide plate. A drain valve 23 is embedded at the front end of the liquid baffle 22. This design solves the problem that existing sweepers lack a dedicated solid-liquid separation device, resulting in garbage that is "muddy" after collection, leading to low utilization of the garbage storage bin volume; and that liquid is prone to leakage and pollution of the road surface during transportation.

[0019] As the first embodiment of this utility model: the lower end of the garbage collection bin 1 is provided with multiple drive wheels, and the upper right side of the garbage collection bin 1 is equipped with a processing module 3, a vision recognition module 4 and a GPS module 5. The processing module 3 has a built-in microcontroller and a battery, and the microcontroller is connected to the multiple drive wheels, the vision recognition module 4, the GPS module 5 and the battery through wires. The GPS module is connected to an external terminal through GPS signals. The vision recognition module 4 is a multi-algorithm camera. The added microcontroller, battery, drive wheels, vision recognition module 4 and GPS module 5 are all existing known devices, and their programming control principles will not be described in detail.

[0020] The servo motor 10 is connected to the drive shaft. This connection allows the servo motor 10 to drive the metal strip 11 and the garbage collection hopper 13 to swing. Sweeping motors 15 are installed at the front and rear positions of the lower right side of the garbage collection hopper 1. Each sweeping motor 15 has a sweeping brush 14 installed at its lower end. The added sweeping motors 15 are powered by a battery via wires, which drives the sweeping brushes 14 to rotate and clean the road. The garbage pusher 16 is located above and behind the first filter screen 19. When the added garbage pusher 16 is moved forward, it pushes out the compressed garbage from the first filter screen 19.

[0021] As a second embodiment of this utility model: the device is controlled to move to the right, shoveling the garbage on the right side into the garbage collection hopper 13. The servo motor 10 is controlled to drive the transmission shaft and the two metal plates 11 to rotate counterclockwise by 180°, which causes the garbage collection hopper 13 to swing and flip, pouring the garbage into the garbage collection box 1 through the garbage inlet 8. Then it falls onto the first filter screen 19. The hydraulic rod 6 is activated, and the movable end of the hydraulic rod 6 drives the pressure plate 7 to move down, which squeezes and compresses the garbage on the first filter screen 19, forcing the liquid to fall through the first filter screen 19 onto the second filter screen 21. Finally, the second filter screen 21 filters the fixed particles, so that the liquid falls to the inclined guide plate and is blocked by the liquid. After the plate 22 is blocked, the box door 2 is opened and the electric telescopic rod 17 is started. The moving end of the electric telescopic rod 17 drives the garbage push plate 16 to move forward, pushing out the compressed garbage on the first filter screen 19. The standard parts used in this utility model can all be purchased from the market. The irregular parts can be customized according to the description and drawings.
