Description

Technical Field

[0001] This utility model belongs to the technical field of garbage truck body structure, specifically relating to a self-unloading garbage truck body structure. Background Technology

[0002] When cleaning existing dump truck containers, the first step is to use tools such as shovels to remove large pieces of solid waste remaining inside the container. Then, a high-pressure hot water cleaner is used to wash the container from top to bottom and from inside to outside. The top and side walls are washed first, and the bottom is washed last, allowing the wastewater to flow naturally to the drain.

[0003] During use, the cleaning work relies heavily on manual operation, especially the pre-treatment stage where shovels are used for removal. This is labor-intensive, creates a harsh environment, is inefficient, and poses safety hazards. Utility Model Content

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Reference Figures 1-3 This is the first embodiment of the present utility model. This embodiment provides a self-unloading garbage truck body structure, including a scraping component, including a body 10, a rear door 11 rotatably connected to the back of the body 10, a guide rail 12 fixedly connected to the top wall of the body 10, a slider 13 slidably connected inside the guide rail 12, a scraper 14 fixedly connected to the bottom of the slider 13, a connecting arm 15 rotatably connected to the back of the back scraper 14, and a pull arm 16 rotatably connected to the end of the connecting arm 15.

[0026] Specifically, when the rear door 11 is opened hydraulically, the linkage structure between the connecting arm 15 and the pull arm 16 can synchronously drive all the scraper blades 14 to move, thereby causing the scraper blades 14 to scrape along the inner wall and bottom plate towards the rear of the container once. This action is like scraping the inner wall of a trash can with a scraper. When the rear door 11 is closed, the linkage mechanism resets the scraper blades to their original position, ready for the next cycle.

[0027] Furthermore, the top outer side of the housing 10 is an inclined structure, and a flip-up door panel is provided at the top of the inclined surface. The guide rail 12 is provided on the outer side of the flip-up door panel, and a fixing rod for synchronous pulling is provided between the sliders 13.

[0028] The flip-up door panel is spaced a certain distance from the edge of the container 10, and the guide rail 12 is placed on the inside of the door panel and the inner wall of the container 10. This ensures that when the garbage is dumped, it will not fall onto the surface of the guide rail 12, and will not affect the movement of the structure below.

[0029] Preferably, the scraper 14 has a concave structure, and the outer side and bottom of the scraper 14 are tightly fitted to the inner wall of the housing 10. The scraper 14 is composed of a bottom strip and a side strip. The thickness of the bottom strip is less than the thickness of the side strip, and the side strip has a hollow structure inside.

[0030] It should be noted that the scraper 14 has a concave structure and is connected to the slider 13 through the guide rails 12 on both sides, so it has high stability. By adhering to the inner wall and bottom of the box 10 through the bottom strip and the side strip, it can scrape off solid waste. At the same time, the bottom strip is thin, so it will not affect the dumping of waste.

[0031] In use, when the rear door 11 is opened by hydraulic control to dump garbage, the rear door 11 will first flip. When the rear door 11 flips, it will pull the pull arm 16, which in turn will pull the connecting arm 15. Through the connection of the fixed rod, all the scraper blades 14 will move synchronously to the rear of the container due to the action of the guide rail 12 and the slider 13. This will cause the scraper blades 14 to scrape the inner wall and bottom plate once, so that large pieces of solid garbage can be automatically scraped off as the rear door 11 opens. Then, they will be dumped with the tilted container 10. When the rear door 11 is closed, the linkage structure will push the scraper blades 14 to reset.

[0032] Example 2

[0033] Reference Figures 4-5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a re-scraping component, including a rotating scraper 20, which is rotatably connected to the inside of the scraper 14. A slotted column 21 is fixedly connected to the top of the rotating scraper 20. A sliding component 22 is provided inside the scraper 14. A first guide rod 23 is fixedly connected to the inner side of the sliding component 22, and a second guide rod 24 is fixedly connected to the outer side of the sliding component 22. A guide groove 25 is provided on the inner wall of the housing 10. The sliding component 22 includes a limiting strip 221, which is fixedly connected to the inside of the scraper 14. A lifting block 222 is slidably connected to the outside of the limiting strip 221.

[0034] Specifically, when the scraper 14 moves, the first guide rod 23 is inserted into the slotted column 21 to guide the rotating scraper 20 to rotate, so that the scraper 14 can scrape away small solid waste scales by contacting the inner wall through the rotating scraper 20 while scraping.

[0035] Furthermore, the rotating scraper 20 consists of a connecting rod in the middle and an outer scraper, and the scrapers are evenly distributed on the outside of the connecting rod and abut against the inner wall of the housing 10. The slotted column 21 has a reciprocating groove for cyclic rotation inside, and the first guide rod 23 is set inside the reciprocating groove, and the diameter of the first guide rod 23 corresponds to the width of the reciprocating groove.

[0036] The rotating scraper 20 is composed of multiple scrapers and can contact the inner wall of the housing 10 in sequence, thus reducing wear and extending service life. Furthermore, by moving up and down through the first guide rod 23, the position inside the reciprocating groove can be changed, enabling the rotating scraper 20 to adapt to the movement of the scraper 14.

[0037] When in use, as the scraper 14 moves, the second guide rod 24 moves inside the guide groove 25, and thus the second guide rod 24 begins to move up and down reciprocally, causing the lifting block 222 to move up and down reciprocally under the limit of the limiting strip 221. At this time, the first guide rod 23 begins to move up and down reciprocally, changing its position inside the reciprocating groove of the slotted column 21. Therefore, the rotating scraper 20 can rotate with the rotation of the slotted column 21. When the rotating scraper 20 rotates, the scraper will contact the inside of the housing 10 in sequence to scrape away small solid scale.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
