DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] refer to Figure 1-7A kitchen waste conveying device comprises a workbench 1, rollers 101 are rotatably connected between the inner walls at both ends of the workbench 1, and a conveyor belt 102 is wound around the outer wall of the roller 101 (it should be noted that in order to prevent the conveyor belt 102 from slipping, a synchronous pulley transmission is preferably used, the roller 101 is preferably a synchronous pulley, and the conveyor belt 102 is preferably a synchronous belt). A box body 2 is provided on the top of the workbench 1, and an extrusion mechanism 201 for dehydrating the kitchen waste is provided inside the box body 2. The extrusion mechanism 201 in this application is the prior art disclosed in the comparative document, and its working principle and connection method are both prior art well known to those skilled in the art, so they are not repeated here. A scraper 3 is provided inside the workbench 1, and the scraper 3 abuts against the surface of the conveyor belt 102. The scraper 3 is rotatably connected to the inner wall of the workbench 1 through a rotating shaft 301. A torsion spring 302 is sleeved on the rotating shaft 301, and one end of the torsion spring 302 is fixedly connected to the inner wall of the workbench 1, and the other end of the torsion spring 302 is fixedly connected to the scraper 3.

[0025] The scraper 3 can be used to scrape off the oil and water on the surface of the conveyor belt 102 to prevent the accumulation of oil and water, thereby reducing the corrosion and wear on the surface of the conveyor belt 102, extending the service life of the conveyor belt 102, and reducing the maintenance cost. The scraper 3 is rotatably connected to the inner wall of the workbench 1 through the rotating shaft 301, and a torsion spring 302 is provided on the rotating shaft 301, so that the oil and water can be evenly scraped off on the entire surface of the conveyor belt 102, thereby improving the scraping efficiency. At the same time, since the surface of the conveyor belt 102 may be uneven due to the attachment of kitchen waste, the torsion spring 302 can be provided to enable the scraper 3 to adapt to the changes in the surface of the conveyor belt 102, thereby ensuring a more uniform scraping effect.

[0026] Secondly, since there may be kitchen waste attached to the surface of the conveyor belt 102, the kitchen waste may not be scraped off by the scraper 3. The scraper 3 is rotatably connected to the inner wall of the workbench 1, so that the kitchen waste attached to the conveyor belt 102 can pass over the scraper 3, avoiding the phenomenon of the kitchen waste not being scraped off by the scraper 3 and causing jamming, thereby improving the transportation stability of the conveyor belt 102.

[0027] In order to achieve a better drying effect, a mounting groove 303 is provided on one side of the workbench 1 close to the box body 2. A hot air blower 304 for drying the surface of the conveyor belt 102 is provided in the mounting groove 303, and the hot air blower 304 is arranged between the scraper 3 and the box body 2. The hot air blower 304 can quickly and thoroughly remove moisture and humidity on the surface of the conveyor belt 102, ensuring that the surface is completely dry, preventing moisture residue, further reducing the accumulation and pollution of oil and water, and extending the service life of the conveyor belt 102.

[0028] Specifically, a filter screen 4 is provided at the bottom of the squeezing mechanism 201, and the filter screen 4 is tilted. An opening 401 is provided on the side of the box body 2 near the filter screen 4 at a low level. A drain port 402 is provided on one side of the bottom of the box body 2, and the drain port 402 is connected to the inside of the box body 2. A drain plate 403 is provided at the drain port 402. The kitchen waste can be separated into dry and wet parts through the filter screen 4, and the oil and water will flow to the bottom of the box body 2 and be discharged through the drain port 402. The kitchen waste will stay on the surface of the filter screen 4. Since the filter screen 4 is tilted, the dry kitchen waste will be affected by gravity and fall to the surface of the conveyor belt 102 through the opening 401.

[0029] By providing the drain port 402 and the drain plate 403 , the filtered oil and water are effectively guided to the outside of the box body 2 , which can prevent the filtered oil and water from falling directly onto the conveyor belt 102 , thereby increasing the service life of the conveyor belt 102 .

[0030] In this embodiment, after the oil-water separation, a portion of the kitchen waste may adhere to the surface of the filter 4 and become unable to be transported. In order to avoid this situation, a scraper 404 is provided on the top of the filter 4, and the scraper 404 is arranged on the side with a high horizontal height of the filter 4. A driving mechanism is provided on the surface of the filter 4 to enable the scraper 404 to scrape off the kitchen waste on the surface of the filter 4.

[0031] When the staff needs to clean the food waste attached to the filter screen 4, the driving mechanism can be started. The driving mechanism will drive the scraper 404 to scrape the food waste remaining on the surface of the filter screen 4 and make it fall onto the conveyor belt 102. At the same time, the staff can regularly start the driving mechanism and the scraper 404 to prevent the surface of the filter screen 4 from being blocked, thereby improving the filtering efficiency of the filter screen 4.

[0032] Specifically, the driving mechanism includes a traction rope 5, an elastic member 501, a winding wheel 502, a gear 503, and a rack 504. The elastic member 501 is a cylindrical compression spring. A squeezing block 604 is provided on the top of the filter screen 4 away from the scraper 404. One end of the elastic member 501 abuts against the scraper 404, and the other end of the elastic member 501 abuts against the squeezing block 604. The winding wheel 502 is rotatably connected to the side of the workbench 1 through a rotating shaft 505. A rotating block 602 is provided on the side of the workbench 1. The rotating shaft 505 is arranged on the rotating block 602 and is rotatably connected to the rotating block 602. One end of the traction rope 5 is fixedly connected to the scraper 404, and the other end of the traction rope 5 is fixedly connected to the winding wheel 502 through a pulley 506. The gear 503 It is arranged on the rotating shaft 505 and fixedly connected to the rotating shaft 505, the rack 504 is arranged on the conveyor belt 102 and fixedly connected to the conveyor belt 102, and the rack 504 is meshed with the gear 503. It should be noted here that the rack 504 is only arranged in a small section (it should be noted that a small section of the rack 504 is arranged on the surface of the conveyor belt 102, which may result in the oil and water on the surface of the conveyor belt 102 in this section being unable to be scraped off by the scraper 3. In order to avoid this situation, it is preferred to arrange the scraper 3 into a "convex" shape structure. It should also be noted that the width of the rack 504 is relatively small, so setting the scraper 3 into a "convex" shape structure will not have a significant impact on the scraping effect of other areas of the conveyor belt 102).

[0033] When the staff starts the conveyor belt 102, the conveyor belt 102 will drive the kitchen waste to move a distance. When the rack 504 on the conveyor belt 102 is meshed with the gear 503, the gear 503 will rotate. At the same time, the gear 503 drives the winding wheel 502 to rotate through the rotating shaft 505. Since the winding wheel 502 is fixedly connected to the traction rope 5, the winding wheel 502 will retract one end of the traction rope 5. At the same time, the other end of the traction rope 5 will pull the scraper 404 to move in the direction of the compression spring. At this time, the scraper 404 will scrape the kitchen waste on the surface of the filter screen 4 and make it fall onto the surface of the conveyor belt 102. The driving mechanism in this embodiment does not require an additional driving source, which reduces costs and improves practicality.

[0034] When the rack 504 is disengaged from the gear 503 under the transportation of the conveyor belt 102, the elastic member 501 will be reset, thereby driving the scraper 404 to reset. In order to prevent the scraper 404 from being offset or misaligned during the movement, guide grooves 6 are provided on both sides of the box body 2, and guide blocks 601 are also provided on both sides of the scraper 404. The guide blocks 601 are slidably connected to the inner wall of the guide groove 6, and the freedom of the guide blocks 601 is limited by the provided guide blocks 601 and the guide groove 6, thereby preventing the scraper 404 from being offset or misaligned during the movement, and improving the stability of the movement of the scraper 404.

[0035] Working principle:

[0036] The staff can place the kitchen waste inside the box 2 and start the squeezing mechanism 201 to dehydrate the kitchen waste. The oil and water will be discharged through the filter screen 4 and the drain port 402. The kitchen waste will be affected by gravity and fall to the surface of the conveyor belt 102 through the opening 401 and be transported. The conveyor belt 102 will drive the kitchen waste to move a distance. When the rack 504 on the conveyor belt 102 is engaged with the gear 503, the gear 503 will rotate. At the same time, the gear 503 drives the reel 502 to rotate through the rotating shaft 505. Since the reel 502 is fixedly connected to the traction rope 5, the reel 502 will retract one end of the traction rope 5. At the same time, the other end of the traction rope 5 will pull the scraper 404 to move in the direction of the compression spring. At this time, the scraper 404 will scrape the kitchen waste on the surface of the filter screen 4 and make it fall on the surface of the conveyor belt 102.

[0037] When the rack 504 is separated from the gear 503 under the transportation of the conveyor belt 102, the elastic member 501 will be reset, thereby driving the scraper 404 to reset. A first inclined surface 603 is provided on the side of the scraper 404 away from the elastic member 501. When the scraper 404 is reset under the action of the elastic member 501, the first inclined surface 603 will move the unscraped kitchen waste to the top of the scraper 404 or to the side of the scraper 404 close to the elastic member 501. In this way, when the rack 504 meshes with the gear 503 next time, the scraper 404 can scrape the kitchen waste that was not scraped last time.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
