Description

Technical Field

[0001] This utility model relates to the field of electric sweeper truck technology, specifically to an electric sweeper truck. Background Technology

[0002] The pure electric sweeper truck is a type of road sweeping and cleaning vehicle in the road sweeper truck series. It has multiple functions such as road cleaning, road sweeping, curb and curbstone facade washing, low-pressure flushing, and spray dust suppression. It integrates the functions of a road sweeper and a high-pressure cleaning truck, realizing sweeping, high-pressure flushing and garbage collection in one operation. It is battery powered, making it more environmentally friendly. The pure electric sweeper truck is suitable for mechanized cleaning, sweeping, and spray dust suppression operations on urban roads, squares, airports, guardrails, curbs and curbstone facades.

[0003] The existing patent publication number CN222183187U discloses an anti-collision device for a road anti-collision sweeper, including a fixed frame fixedly installed at the rear of the sweeper, with hinge seats symmetrically arranged on the left and right sides of the rear of the fixed frame, and a horizontally arranged clearance frame movably installed on the hinge seats through a pin. This utility model's anti-collision box achieves an anti-collision function. When the sweeper truck dumps garbage, the pin on one side of the fixed frame is removed, and the push rod pushes the movable frame and the anti-collision box to flip laterally to one side of the fixed frame, preventing the anti-collision box from obstructing garbage collection and dumping. It eliminates the need for frequent disassembly and assembly. This utility model has a simple structure and is extremely convenient to use, making it suitable for widespread adoption. However, although the pin on one side of the fixed frame can be removed and the push rod pushes the movable frame and the anti-collision box to flip laterally to one side of the fixed frame when the electric sweeper truck needs to dump garbage, thus preventing the anti-collision box from obstructing garbage collection and dumping, it is still necessary to manually rotate the anti-collision box to one side before each dumping and manually rotate it back to its original position after dumping. This still presents inconvenience. Therefore, we proposed an electric sweeper truck to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides an electric sweeper truck, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] An electric sweeper truck includes a vehicle body. A water tank and a garbage collection bin are fixed to the top of the vehicle body. A protective shell for protecting the garbage collection fan is installed between the water tank and the garbage collection bin. A rear baffle is fixed inside the garbage collection bin. A garbage discharge outlet is opened on the rear baffle. Two hydraulic cylinders are installed on the rear baffle. A sealing plate for protecting the garbage discharge outlet is rotatably connected to one side wall of the rear baffle via a pin. The top end of each hydraulic cylinder is rotatably connected to the sealing plate. An mounting plate is fixed to the sealing plate. Three buffer seats are fixed to one side wall of the mounting plate. A buffer plate is provided on one side of the mounting plate. Four damping buffers are fixed inside each buffer seat.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides an electric sweeper truck, which has the following beneficial effects:

[0016] This invention fixes a mounting plate with a buffer seat and other components to a sealing plate. When dumping garbage, the sealing plate rotates and opens, simultaneously driving the mounting plate to rotate. This avoids affecting the garbage dumping process and eliminates the need for manual removal and rotation of the mounting plate and buffer components, making it convenient to use. Furthermore, a partition plate inside the garbage collection bin separates the collected garbage into solid and liquid components, reducing the moisture content of the separated solid garbage for easier subsequent processing. The internal auger facilitates the discharge of solid garbage into the garbage collection bin. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, an embodiment of the electric sweeper truck of this utility model includes a vehicle body 1. A water storage tank 2 and a garbage collection box 3 are fixed on the top of the vehicle body 1. A protective shell 4 for protecting the garbage collection fan is provided between the water storage tank 2 and the garbage collection box 3. A rear baffle 5 is fixed inside the garbage collection box 3. A garbage discharge outlet 6 is opened on the rear baffle 5. Two hydraulic cylinders 7 are installed on the rear baffle 5. A sealing plate 8 for protecting the garbage discharge outlet 6 is rotatably connected to one side wall of the rear baffle 5 by a pin. The top end of each hydraulic cylinder 7 is rotatably connected to the sealing plate 8. A mounting plate 9 is fixed on the sealing plate 8. Three buffer seats 10 are fixed to the side wall. A buffer plate 11 is provided on one side of the mounting plate 9. A warning reflective strip 22 is fixed to one side wall of the buffer plate 11. There are four warning reflective strips 22. The warning reflective strips 22 can further warn and remind vehicles and pedestrians to avoid collisions with the rear of the sweeper. Four damping buffers 12 are fixed inside each buffer seat 10. One end of each damping buffer 12 is rotatably connected to a connecting rod 13 by a pin. The other end of each connecting rod 13 is rotatably connected to the buffer plate 11 by a pin. Four telescopic sleeves 14 are fixed inside each buffer seat 10. The other end of the sleeve 14 is fixedly connected to the buffer plate 11. During the use of this electric sweeper, a water spraying assembly, a sweeping assembly, and other components for garbage collection and disposal are installed under the vehicle body 1. A drive unit is also installed at the front of the vehicle body 1. Since many components on the sweeper are based on existing technologies and operating principles, they are not described in detail here. When a rear-end collision occurs and impacts the buffer plate 11, the buffer plate 11 transmits the force to the connecting rod 13. The force is then transmitted through the connecting rod 13 to the damping buffer 12. Finally, the damping buffer 12 absorbs the force. The buffer provides a certain degree of protection for the rear of the vehicle body 1. The three buffer seats 10 are fixed on the mounting plate 9, which in turn is fixed on the sealing plate 8. Therefore, when the garbage inside the garbage collection bin 3 is discharged, the top end of the two hydraulic cylinders 7 is retracted, which drives the sealing plate 8 to rotate. After the sealing plate 8 rotates, the blockage of the garbage discharge outlet 6 can be released, and then the garbage can be discharged. Since the mounting plate 9 is fixed on the sealing plate 8, the mounting plate 9 will rotate and open synchronously with the sealing plate 8. Thus, when dumping garbage, there is no need to manually operate the anti-collision buffer components and rotate them to one side of the garbage collection bin 3.

[0027] like Figure 2 and Figure 3As shown, in some embodiments, a partition plate 15 is fixed inside the garbage collection bin 3. Filter screens 16 are fixed inside each of the two openings on the partition plate 15. Two augers 17, adapted to the filter screens 16, are rotatably connected inside the garbage collection bin 3 via bearings. Spiral sealing strips 18 are fixed to the surface of each auger 17, and these spiral sealing strips 18 are tightly fitted to the corresponding filter screens 16. The spiral sealing strips 18 enhance the tightness of the fit between the spiral blades of the auger 17 and the filter screens 16, facilitating more thorough discharge of solid waste. During use, the partition plate 15 allows for the sorting of garbage collected inside the garbage collection bin 3. Solid-liquid separation is performed. Solid waste will remain on the separator plate 15, while liquid will pass through the filter screen 16 and remain in the cavity at the bottom of the waste collection bin 3. When solid waste needs to be discharged, the sealing plate 8 is opened, and the motor is started to drive the two augers 17 to rotate. After the two augers 17 rotate, the solid waste can be discharged into the waste collection bin 3. When the separated liquid needs to be discharged into the waste collection bin 3, it can be discharged from the drain port on the back of the waste collection bin 3. The drain port is connected to a drain pipe, and a valve is installed on the drain pipe, but the two are not shown in the figure.

[0028] like Figure 3 As shown, in some embodiments, sprockets 17 are fixed to the surface of each auger 17. The two sprockets 19 are connected by a chain 20. With the cooperation of the sprockets 19 and the chain 20, the two augers 17 can be driven to rotate simultaneously under the action of the same motor, thereby saving production costs.

[0029] like Figure 4 and Figure 5 As shown, in some embodiments, a telescopic cover 21 is fixed to one side wall of the buffer seat 10, and the other end of the telescopic cover 21 is fixedly connected to the buffer plate 11. The telescopic cover 21 can protect the damping buffer 12 so as to extend its service life.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
