Description

Technical Field

[0001] This utility model belongs to the field of rear protection technology for catering carts. Specifically, this utility model relates to a rear protection mechanism for catering carts. Background Technology

[0002] Traditional food waste trucks have two types of rear protection structures. One type uses a special device instead of a dedicated one, while the other type connects the rear protection directly to the chassis. With the latter type, food waste will spill onto the rear protection when the truck is unloading, causing it to become contaminated. If the truck is not washed, the food waste remaining on the rear protection during secondary operations may drip and cause secondary pollution of the road surface and emit foul odors.

[0003] Chinese Patent (Publication No.: 216376028U) discloses a kitchen waste truck unloading mask cover, a kitchen waste truck container, and a kitchen waste truck. The kitchen waste truck unloading mask cover includes an open front end, a closed rear end opposite the front end in the depth direction of the cover, a side portion connecting the front and rear ends along their outer peripheries, and a sealing strip adaptedly fixed in an annular groove in the front end. The annular groove is constructed to be recessed a first distance from the front face of the front end facing the unloading port toward the rear end, and the sealing strip has an extension height greater than the first distance. However, this kitchen waste truck unloading mask cover, kitchen waste truck container, and kitchen waste truck are prone to contamination of the rear protective gear during waste disposal. Utility Model Content

[0004] This utility model is designed to solve the above-mentioned problems and aims to provide a rear protection mechanism for a catering vehicle that does not contaminate the rear protection. To achieve the above objective, the technical solution adopted by this utility model is as follows: a rear protection mechanism for a catering vehicle, including a box and a tailgate, wherein a sliding shovel and a drive structure connected to the sliding shovel are provided in the box, and a protective structure is provided on the tailgate.

[0005] The protective structure includes inclined support plates, which are arranged on both sides of the tailgate, and rear protection is provided on the inclined support plates.

[0006] A hydraulic cylinder is installed at the top of the box body, the hydraulic rod of the hydraulic cylinder is connected to the tailgate, and the tailgate is connected to the vehicle body pivot.

[0007] The drive structure includes a hydraulic cylinder, which is installed inside the housing. The hydraulic cylinder's hydraulic rod is connected to the sliding shovel.

[0016] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0017] like Figure 1As shown, a rear protection mechanism for a food waste truck includes a container 1 and a tailgate 2. The container 1 houses a sliding shovel 3 and a drive structure 4 connected to the sliding shovel 3. A protective structure 5 is installed on the tailgate 2. The container 1 holds a large amount of food waste, providing a sealed storage space to prevent spillage during transportation. The tailgate 2 seals the rear of the container 1, effectively preventing waste from falling from the rear of the container 1 during transport, ensuring cleanliness and safety. The drive structure 4 provides power and guidance for the movement of the sliding shovel 3, which pushes the food waste inside the container towards the container for smooth discharge. The protective structure 5, originally located at the rear of the vehicle, is now installed on the tailgate 2, reducing contamination of the protective structure 5 caused by waste exiting the container 1 when the tailgate 2 is opened.

[0018] The protective structure 5 includes inclined support plates 501, which are located on both sides of the tailgate 2. A rear guard 502 is mounted on the inclined support plates 501. The inclined support plates 501 are welded to both sides of the tailgate 2 to install the rear guard 502, which is a rear anti-collision beam for automobiles. By mounting the rear guard 502 on the inclined support plates 501, the rear guard 502 can rotate with the tailgate 2. When the tailgate 2 is opened to push out garbage, the pollution caused by garbage pushing out of the container body 1 to the protective structure 5 is reduced.

[0019] A hydraulic cylinder 6 is installed at the top of the cargo box 1. The hydraulic rod of the cylinder 6 is connected to the tailgate 2, and the tailgate 2 is connected to the vehicle body's pivot shaft. One end of the cylinder 6 is connected to the top of the cargo box 1 via the pivot shaft, and the hydraulic rod of the cylinder 6 is connected to the tailgate 2 via the pivot shaft. When the tailgate 2 rotates around its own pivot shaft relative to the vehicle body, both ends of the cylinder 6 can flexibly adjust their angles via their respective pivot shafts, preventing the cylinder from being twisted due to positional changes caused by the opening and closing of the tailgate. During the tailgate opening process, the cylinder 6 will swing as the tailgate angle changes. The dual pivot shaft structure can eliminate stress concentration caused by rigid connections, ensuring that the cylinder 6 is always in a reasonable stress posture.

[0020] The drive structure 4 includes a hydraulic cylinder 401, which is installed inside the housing 1. The hydraulic rod of the hydraulic cylinder 401 is connected to the sliding shovel 3. Slide rails 402 are provided on both sides of the housing 1, and sliders are provided on both sides of the sliding shovel 3, with the sliders engaging with the slide rails 402. The hydraulic cylinder 401 is fixedly installed at one end of the housing 1, and its hydraulic rod is connected to the sliding shovel 3. The slide rails 402 are located on both sides of the housing 1, and the sliders are connected to the sliding shovel 3, embedding themselves within the slide rails 402, with a sliding engagement between the sliders and the slide rails 402. The driving force provided by the hydraulic cylinder 401, combined with the guiding and limiting functions of the slide rails 402 and the sliders, forms a stable drive. The power of the hydraulic cylinder 401 is transmitted to the waste through the sliding shovel 3, while the slide rails 402 and the sliders ensure that the sliding shovel 3 moves in a straight line, effectively pushing the waste out of the vehicle.

[0021] A reinforcing plate 7 is provided between the inclined support plate 501 and the rear guard plate 502. The reinforcing plate 7 is provided between the inclined support plate 501 and the guard plate 502 to enhance the stability of the connection between the inclined support plate 501 and the guard plate 502, improve the overall strength of the inclined support plate 501, and cope with the impact force during operation.

[0022] The sliding shovel 3 includes a vertical plate 301, with a right-angled triangle 302 connected to its bottom end. The inclined surface of the right-angled triangle 302 serves as the waste pushing surface. The vertical plate 301 transmits driving force, transferring the pushing force to the right-angled triangle 302. The vertical plate 301 evenly transmits the pushing force output by the hydraulic cylinder 401 to the right-angled triangle 302, ensuring that the power is applied to the waste. The inclined surface of the right-angled triangle 302 serves as the waste pushing surface. One vertical plate of the right-angled triangle 302 is connected to the vertical plate 301, fixing the right-angled triangle 302 in place. The other vertical plate of the right-angled triangle 302 is in contact with the bottom surface of the container 1. When the sliding shovel 3 moves to push material, it can further reduce the bottom gap, preventing waste from leaking through the gap between the right-angled triangle 302 and the bottom surface of the container 1, improving the cleaning effect of waste at the bottom of the container and reducing the amount of residue. Furthermore, the right-angled triangular plate 302, which is attached to the bottom surface of the container 1, can provide auxiliary support. During the material pushing process, when the inclined surface of the right-angled triangular plate 302 is subjected to pressure from the waste, the plate attached to the bottom surface can transfer part of the force to the bottom surface of the container 1, dispersing the load on the right-angled triangular plate 302, preventing damage due to excessive local stress, and extending the service life of the right-angled triangular plate 302. At the same time, the design of being attached to the bottom surface also makes the sliding shovel 3 move more smoothly.

[0023] The rear guard 502 is connected to the inclined support plate 501 by bolts. The connection between the rear guard 502 and the inclined support plate 501 by bolts facilitates the disassembly of the rear guard 502 and allows for the replacement of the rear guard 6.

[0024] The inclined plate of the right-angled triangle 302 forms a 45-degree angle with the horizontal plane. The 45-degree angled plate creates a smooth pushing trajectory. Food waste often contains liquids and viscous substances, which easily stick to the bottom of the bin. When moving, the 45-degree angled plate can generate a continuous forward pushing force on the waste, and the tilt angle can guide the waste to slide along the plate surface. Compared with gentler or steeper angles, the 45-degree angle can achieve a balance between pushing force and guidance, allowing the waste to be pushed more smoothly, reducing jamming during the pushing process, and thus shortening the unloading time per cycle.

[0025] The role and effect of the embodiments

[0026] Power is provided by hydraulic cylinder 401, and guide and limit the slide rail 402 and slider to ensure stable linear movement of the slide shovel 3. The vertical plate 301 of the slide shovel 3 transmits thrust. The right-angled triangular plate 302 can push garbage with less effort and reduce garbage residue through the 45-degree inclined plate surface. The protective structure 5 is moved to the tail gate 2. The inclined support plate 501 is welded and fixed, and the connection stability with the rear protection 502 is enhanced by the reinforcing plate 7. The rear protection 502 rotates with the tail gate. When the slide shovel 3 pushes the garbage out of the box 1, it can reduce garbage contamination of the rear protection 502. The rear protection 502 is bolted to the inclined support plate 501 for easy disassembly and replacement of the rear protection 502. The cylinder 6 connects the box and the tail gate 2 with double rotating shafts to avoid twisting under force and ensure smooth opening and closing of the tail gate. Through the coordinated work of various structures, the efficiency of garbage loading and unloading, the safety of transportation, and the durability of the equipment are achieved, and the contamination of the rear protection 502 by garbage is reduced.
