Description

Technical Field

[0001] The invention belongs to the technical field of sanitation vehicles, in particular to a self-loading and unloading electric sanitation vehicle. Background Art

[0002] Sanitation vehicles are special vehicles used for urban appearance tidying and cleaning; they mainly include sweepers, sprinkler trucks, garbage trucks, and sewage suction trucks; Among them, garbage trucks refer to special vehicles used by municipal sanitation departments to transport various types of garbage. They are divided into: compression garbage trucks, swing arm garbage trucks, hook arm garbage trucks, self-loading garbage trucks, etc. Garbage trucks mainly carry domestic garbage, and can also transport bulk building materials such as ash, sand, stone, and soil; A self-loading and unloading garbage truck refers to a dump truck that uses the vehicle's equipment and power, in conjunction with a fixed container for collecting garbage (such as a garbage bin, etc.), to load, transport and unload garbage by itself.

[0003] When using a self-loading garbage truck to collect garbage, first you need to push the garbage can to the side of the self-loading garbage truck, then align the edge of the garbage can with the block on the self-loading garbage truck, and then use the hydraulic cylinder to push the box cover to rotate. The rotating box cover will pull the loading and unloading mechanism upward through the pull rod, thereby driving the garbage can to move upward. When the garbage can moves to the top, the opening of the garbage can is facing the top, so that the garbage in the garbage can can be poured into the garbage bin; Since the garbage in some trash cans contains liquid, when the liquid is mixed with the garbage, some of the garbage will easily adhere to the bottom of the trash can. When the garbage in the trash can is poured out by a self-loading garbage truck, the garbage adhered to the trash can cannot be poured out, so the garbage in the trash can needs to be cleaned manually.

[0012] The beneficial effects of the present invention are as follows: 1. The self-loading and unloading electric sanitation vehicle described in the present invention is provided with a cleaning component. When garbage adheres to the bottom of a trash can, the cleaning block is controlled to extend into the trash can and scrape the bottom of the trash can, so that the garbage or sludge adhered to the bottom of the trash can can be scraped off. The scraped garbage or sludge will fall into the trash bin. In this process, it can be avoided that when the garbage adhered to the trash can cannot be poured out, the garbage can needs to be cleaned manually, thereby avoiding the workers from being subjected to unpleasant odors when cleaning the trash can, and the garbage will also adhere to the workers' hands.

[0013] 2. The self-loading and unloading electric sanitation vehicle described in the present invention, when it is necessary to empty garbage cans of different heights, controls the extension or contraction of the fourth hydraulic cylinder according to the height of the garbage can. During the extension or contraction of the fourth hydraulic cylinder, it will drive the second n-type frame to move up and down along the first n-type frame, and the second n-type frame moving up and down will drive the pallet to move up and down. When the pallet moves to below the edge of the garbage can, the garbage in the garbage can can be emptied. Compared with the prior art, the position of the pallet is fixed and garbage cans of different heights cannot be emptied. If the height of the garbage can is lower than the pallet, the garbage can needs to be manually hung on the pallet.

[0014] 3. The self-loading and unloading electric sanitation vehicle described in the present invention has a support plate fixedly connected to the lower part of the block by an extension rod. When dumping garbage, the garbage can is first pushed onto the support plate, and then when the second n-type frame moves up, the support plate will be driven up, thereby driving the garbage can up. In this process, it can be prevented that when the edge of some garbage cans is damaged, the card plate cannot be stuck on the edge of the garbage can, thereby making it impossible to pull up the garbage can with damaged edge, and therefore, it is impossible to dump garbage from these garbage cans.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] Embodiment 1: Figures 1 to 12 As shown, the self-loading and unloading electric sanitation vehicle of the present invention comprises a garbage collection vehicle; a garbage box 1 is installed on the garbage collection vehicle; a garbage opening 11 is opened on the top of the garbage box 1; The trash bin 1 is provided with a loading and unloading mechanism; the loading and unloading mechanism comprises two tracks 12, and the tracks 12 are in an inverted L shape and are fixedly mounted on the trash bin 1; the track 12 located at the top of the trash bin 1 is tilted downward; the trash opening 11 is located between the two tracks 12; A cover door 13 is rotatably mounted on the trash bin 1 between the two rails 12, and the other side of the cover door 13 extends to a side position of the rail 12 vertically downward; the cover door 13 is controlled to open and close by a first hydraulic cylinder 131; A loading and unloading assembly is provided between the two rails 12; the disassembly assembly includes a first n-shaped frame 2; the first n-shaped frame 2 is located between the two rails 12; both end surfaces of the first n-shaped frame 2 close to the rails 12 are rotatably connected to two rotating wheels 21, and the rotating wheels 21 rotate in the opposite rails 12; a baffle 22 is fixedly connected to the side of the first n-shaped frame 2 away from the trash can 1; A second n-shaped frame 23 slides inside the first n-shaped frame 2 through a slideway; a clamping plate 24 is fixedly connected to the top of the second n-shaped frame 23 on the side of the second n-shaped frame 23 away from the trash bin 1; A stopper 25 is fixedly connected to the second n-shaped frame 23 below the clamping plate 24; pull rods 26 are rotatably mounted on the second n-shaped frame 23 on both sides of the stopper 25, and the other end of the pull rod 26 extends to the bottom of the cover door 13 and is rotatably connected to the cover door 13; A cleaning assembly is provided above the garbage opening 11, and is initially located below the cover door 13; the cleaning assembly includes a rotating plate 3; the rotating plate 3 is located below the cover door 13 and rotates on the garbage bin 1; a second hydraulic cylinder 31 is rotatably mounted on one side of the rotating plate 3 away from the track 12, and the other side of the second hydraulic cylinder 31 is rotatably mounted on the garbage bin 1; A third hydraulic cylinder 32 is installed in the rotating plate 3, and a cleaning block 33 is provided on the extension rod of the third hydraulic cylinder 32; the cleaning block 33 has an inclined surface on the side facing the track 12; a slide groove 34 is provided in the cleaning block 33, and the extension rod of the third hydraulic cylinder 32 slides in the slide groove 34, and the extension rod of the third hydraulic cylinder 32 is connected to the slide groove 34 through a spring; Specifically, when collecting garbage in the garbage bin 15, the garbage bin 15 is first pushed between the two tracks 12 and the garbage bin 15 is brought into contact with the block 25. Then, the first hydraulic cylinder 131 is controlled to extend, and the first hydraulic cylinder 131 will push the cover door 13 to gradually rotate, and the garbage opening 11 will no longer be blocked. The gradually rotating cover door 13 will drive the pull rod 26 to move upward, and the upwardly moving pull rod 26 will drive the second n-shaped frame 23 to gradually move upward, and the card plate 24 on the second n-shaped frame 23 will gradually get stuck in the bucket edge of the garbage bin 15. Then, the second n-shaped frame 23 will drive the garbage bin 15 to move upward, and the upwardly moving garbage bin 15 will gradually contact the baffle plate 24 on the first n-shaped frame 24. 22 contact, when the trash can 15 contacts the baffle 22, the trash can 15 will push the baffle 22 to move up, and the baffle 22 will drive the first n-shaped frame 2 to move up, and the moved first n-shaped frame 2 will drive the wheels 21 on both sides to move in the track 12, as the cover door 13 gradually rotates, the first n-shaped frame 2 and the second n-shaped frame 23 will be pulled up gradually through the pull rod 26, when the cover door 13 rotates to the extreme position, the wheels 21 on the second n-shaped frame 23 will rotate to the position above the trash can 1, at this time, the first n-shaped frame 2, the second n-shaped frame 23 and the opening of the trash can 15 are all tilted downward, and the garbage in the trash can 15 will be poured into the trash can 1; More specifically, if there is garbage stuck in the trash can 15, when the trash can 15 follows the first n-shaped frame 2 to move to the top position of the trash box 1, and the opening of the trash can 15 is tilted downward, the second hydraulic cylinder 31 is controlled to contract. During the contraction of the second hydraulic cylinder 31, the rotating plate 3 will be pulled to rotate toward the position of the trash can 15. The rotating rotating plate 3 drives the third hydraulic cylinder 32 and the cleaning block 33 to rotate. When the cleaning block 33 is parallel to the trash can 15, the second hydraulic cylinder 31 stops contracting, and then the third hydraulic cylinder 32 gradually extends, thereby driving the cleaning block 33 to gradually extend into the trash can 15. Since the side of the cleaning block 33 facing the track 12 is an inclined surface, the cleaning block 33 entering the trash can 15 will move along the side wall of the inner cavity of the trash can 15. When the cleaning block 33 moves to the bottom position of the trash can 15, the cleaning block 33 is blocked by the trash can 15 and cannot be The third hydraulic cylinder 32 is controlled to stop extending, and the second hydraulic cylinder 31 is controlled to continue to contract. The contracted second hydraulic cylinder 31 will continue to drive the rotating plate 3 to rotate, thereby driving the cleaning block 33 to rotate from bottom to top in the trash can 15. During the rotation of the cleaning block 33, it will rotate along the bottom of the trash can 15, so that the garbage adhered to the bottom of the trash can 15 can be scraped off. Since the extension rod of the third hydraulic cylinder 32 slides in the slide groove 34, when the cleaning block 33 rotates, in order to adapt to the contour of the bottom of the trash can 15, the cleaning block 33 will slide on the extension rod of the third hydraulic cylinder 32, thereby preventing the cleaning block 33 from being fixed and unable to slide on the extension rod of the third hydraulic cylinder 32, thereby preventing it from moving along the bottom of the trash can 15. Further, when the cleaning block 33 finishes scraping the bottom of the trash can 15, the third hydraulic cylinder 32 is controlled to restore to the initial state, and then the second hydraulic cylinder 31 is controlled to restore to the initial state. When the garbage is emptied, the cover door 13 is controlled to rotate in the opposite direction, and the first n-type frame 2 and the second n-type frame 23 can be pushed to restore to the initial state through the pull rod 26; By setting up a cleaning component, when garbage is adhered to the bottom of the trash can 15, the cleaning block 33 is controlled to extend into the trash can 15 and scrape the bottom of the trash can 15, so that the garbage or sludge adhered to the bottom of the trash can 15 can be scraped off, and the scraped garbage or sludge will fall into the trash bin 1. In this process, it can be avoided that when the garbage adhered to the trash can 15 cannot be poured out, the trash can 15 needs to be cleaned manually, thereby avoiding the workers from being subjected to unpleasant odors when cleaning the trash can 15, and the garbage will also adhere to the workers' hands.

[0020] Embodiment 2: Two arc grooves 14 are provided in the track 12 on both sides of the garbage opening 11, and the diameter of the arc groove 14 is the same as the diameter of the rotating wheel 21; In this embodiment, a rubber layer is fixedly connected to the outer ring surface of the rotating wheel 21; In this embodiment, the top end of the pull rod 26 is fixedly connected to a fourth hydraulic cylinder 27; the other end of the fourth hydraulic cylinder 27 is rotatably mounted on the cover door 13; Specifically, when the rotating wheel 21 moves along the track 12 to the top of the trash bin 1, the rotating wheel 21 will pass through the arc groove 14. When the rotating wheel 21 passes through the arc groove 14, the first n-shaped frame 2, the second n-shaped frame 23 and the trash bin 15 will shake. When the trash bin 15 shakes, the trash in the trash bin 15 can be poured out more easily, avoiding the trash from being piled up in the trash bin 15 and being unable to be poured out. More specifically, since the outer ring surface of the runner 21 is fixedly connected with a rubber layer, when the runner 21 passes through the arc groove 14, the rubber layer can protect the runner 21, thereby preventing the runner 21 from directly contacting the arc groove 14 and causing damage to the runner 21; Furthermore, since the fourth hydraulic cylinder 27 fixedly connected to the top of the pull rod 26 is rotatably installed on the cover door 13, when the cover door 13 is rotated to the extreme position, the opening of the trash can 15 tilts downward. At this time, the fourth hydraulic cylinder 27 is controlled to cyclically extend and then contract, thereby pushing the second n-type frame 23 to move back and forth through the pull rod 26. The back-and-forth moving second n-type frame 23 will drive the trash can 15 to move back and forth, thereby shaking the garbage in the trash can 15, so that the garbage in the trash can 15 can be poured out more easily.

[0021] Embodiment 3: The stopper 25 is provided with evenly arranged extension rods 4; The extension rod 4 extends to a downward position; a support plate 41 is fixedly connected to one side of the extension rod 4 extending downward, and the height from the support plate 41 to the card plate 24 is equal to the height from the bottom of the trash can 15 to the edge of the trash can 15; In this embodiment, the extension rod 4 is a threaded rod, passes through the stopper 25, and is slidably connected to the stopper 25; The stopper 25 is located above the extension rod 4 and is threadedly engaged with a limit nut 401; Specifically, when it is necessary to empty trash cans 15 of different heights, the fourth hydraulic cylinder 27 is controlled to extend or contract according to the height of the trash can 15. During the extension or contraction of the fourth hydraulic cylinder 27, the second n-shaped frame 23 will be driven to move up and down along the first n-shaped frame 2. The second n-shaped frame 23 moving up and down will drive the pallet 24 to move up and down. When the pallet 24 moves to the bottom of the bucket edge of the trash can 15, the trash in the trash can 15 can be emptied. Compared with the prior art, the position of the pallet 24 is fixed and it is impossible to empty trash cans 15 of different heights. If the height of the trash can 15 is lower than the pallet 24, it is still necessary to manually hang the trash can 15 on the pallet 24. More specifically, since the support plate 41 is fixedly connected to the lower part of the stopper 25 by the extension rod 4, when dumping garbage, the garbage can 15 is first pushed onto the support plate 41, and then when the second n-shaped frame 23 moves up, the support plate 41 is driven to move up, thereby driving the garbage can 15 to move up. In this process, it can be prevented that when the edge of some garbage cans 15 is damaged, the card plate 24 cannot be used to get stuck on the edge of the garbage can 15, so that the garbage can 15 with damaged edge cannot be pulled up, and therefore the garbage can 15 cannot be dumped; Furthermore, when it is necessary to empty trash cans 15 of different heights, first adjust the height of the support plate 41 to the card plate 24 according to the height from the bottom of the trash can 15 to the edge of the trash can. When adjusting, first control the extension rod 4 to slide in the block 25. When the extension rod 4 reaches the appropriate position, rotate the limit nut 401 to make the limit nut 401 contact with the top of the block 25, and then the trash can 15 can be dumped.

[0022] Embodiment 4: The support plate 41 includes a left half plate 42 and a right half plate 43; the extension rod 4 is fixedly connected to the right half plate 43; The left half plate 42 is fixedly connected to a connecting rod 44 on one side facing the right half plate 43, and the other side of the connecting rod 44 slides in the right half plate 43, and the connecting rod 44 cannot slide out of the right half plate 43; In this embodiment, a notch 45 is formed on a side of the left half plate 42 away from the right half plate 43; A baffle 46 is rotated in the notch 45 by a torsion spring, and in the initial state, the baffle 46 partially extends above the left half plate 42; the baffle 46 can be rotated into the notch 45; The left side of the blocking piece 46 is located in the notch 45 and is fixedly connected with a blocking plate 47, and the blocking plate 47 is located at the upper left position of the center of the blocking piece 46; Specifically, since the support plate 41 is composed of a left half plate 42 and a right half plate 43, when the trash can 15 is dumped, the overall length of the support plate 41 can be adjusted according to the length of the trash can 15. By pulling the left half plate 42, the left half plate 42 will drive the connecting rod 44 to slide in the right half plate 43, so that the length of the support plate 41 can be adjusted according to the length of the trash can 15, thereby avoiding a large deviation between the length of the support plate 41 and the length of the trash can 15, which will affect the process of lifting the trash can 15. More specifically, when the trash can 15 needs to be dumped, the support plate 41 is first controlled to move down and fit the ground. During the process of the support plate 41 fitting the ground, the ground will push the blocking piece 46 to rotate, and the blocking piece 46 will turn into the notch 45. Then the trash can 15 is pushed onto the support plate 41 until the trash can 15 completely passes through the notch 45. When the support plate 41 drives the trash can 15 off the ground, the blocking piece 46 will return to its initial state under the action of the torsion spring, thereby blocking the trash can 15. If the trash can 15 slides on the support plate 41, the blocking piece 46 will be pushed to rotate toward the position of the baffle plate 47. When the blocking piece 46 contacts the baffle plate 47, the blocking piece 46 will no longer rotate, thereby blocking the trash can 15 and preventing the trash can 15 from sliding off the support plate 41.
