Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a device for unclogging the rear door of a garbage bin. Background Technology
[0002] Garbage trucks typically unload using either a push-pump or a tilting mechanism. Tilting unloading is generally divided into two types: a moving unloading door and a hydraulically operated fully open door. With a moving unloading door, the rear door latch is opened, the garbage container is tilted, and the rear door opens under gravity. With a hydraulically operated fully open door, the latch is opened, the rear door opens, and the garbage is dumped from the fully open rear door position.
[0003] The push-shovel unloading method uses power unloading, so there is no need to worry about garbage blockage. However, the design of the push-shovel and the multi-stage hydraulic cylinder that drives it also has other shortcomings: 1. The push-shovel, hydraulic cylinder and other connecting accessories increase manufacturing costs; 2. It occupies the internal space of the garbage bin, thereby reducing the space for garbage loading; 3. It reduces the overall vehicle load factor, thereby increasing the cost of garbage transfer and transportation.
[0004] The tipping method for unloading relies on the weight of the waste itself to exit the truck. However, if the compressed waste has high expansion potential but is relatively light (e.g., foam packaging, paper flowers, plastic bags), the downward force of the waste along the truck bed's floor when the truck is tipped over may be less than the frictional force exerted by the waste on the truck's inner walls and floor, leading to a blockage. In severe cases, manual removal is usually required to resolve this issue.
[0005] Therefore, how to provide a garbage bin rear door unblocking device with a simpler and more reasonable structural design that can automatically clear blockages at the rear of the garbage bin and better complete the unloading process has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content
[0006] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this utility model is how to provide a garbage bin rear door unblocking device with a simpler and more reasonable structural design that can automatically unblock garbage at the rear of the garbage bin and better complete the unloading process.
[0007] To achieve the above objectives, this utility model provides a garbage bin rear door unblocking device, including a bin door that is hinged to the upper rear end of the garbage bin and can be vertically rotated via a hinged installation structure; a bin door opening and closing control structure is provided between the bin door and the garbage bin for controlling the opening and closing of the bin door; characterized in that; an unblocking device is also provided on the bin door, the unblocking device including a garbage unblocking rod installed on the inner side of the upper end of the bin door and extending inward into the garbage bin.
[0008] In this way, when the aforementioned garbage bin rear door unblocking device is working, the door opening and closing control structure controls the opening of the bin, and at the same time, the garbage unblocking rod installed on the inner side of the upper part of the bin door also rotates with the bin door. This allows garbage that is prone to clogging at the upper part of the garbage bin's discharge port to be carried out, achieving the initial unblocking purpose. If the garbage inside the bin still cannot be discharged smoothly, the bin door can be repeatedly opened and closed to drive the garbage unblocking rod, shaking or digging out the garbage. The above structure can automatically unblock the garbage at the rear of the bin while the bin door is opening, enabling better unloading.
[0009] As an optimization, the garbage unblocking rods are arranged in pairs, with each of the two garbage unblocking rods located on the horizontal edges of the container door.
[0010] In this way, two garbage unblocking rods are designed, and each of the two garbage unblocking rods is placed on the horizontal edge of the door. This allows for the application of force to better unblock the garbage on both sides of the rear of the garbage bin, making the arrangement more reasonable.
[0011] As an optimization, the garbage unblocking rod includes a connecting plate with a long strip-shaped plate structure at the rear end, and the rear end of the connecting plate is fixed to the inner side of the box door; a working plate with a rectangular plate structure is connected to the front end of the connecting plate, and a force application notch is provided on the lower side of the working plate.
[0012] In this way, the structure of the garbage unblocking rod is simpler and more reasonable. By setting a force application notch at its front end, it can better drive the garbage at the rear of the garbage bin to move outward.
[0013] Furthermore, reinforcing blocks with a triangular structure are provided on both sides of the inner end of the connecting plate.
[0014] Furthermore, a vertically penetrating connection notch is provided at the front end of the connecting plate, and the rear end of the working plate is inserted and installed in the connection notch.
[0015] As an optimization, the hinged mounting structure includes hinge ear plates connected and fixed to the upper end face of the bin door, and a hinge seat is provided on the garbage bin for each corresponding hinge ear plate, and the hinge ear plates are hinged to the hinge seats through a hinge shaft.
[0016] In this way, the hinged installation structure design is simpler and more reasonable, making it easier to hinge the door onto the garbage bin.
[0017] Furthermore, there are three hinged lugs arranged at intervals along the transverse direction of the door.
[0018] Furthermore, a base plate is installed and fixed on the upper surface of the door, and the hinge ear plate is installed and fixed on the base plate.
[0019] Furthermore, a reinforcing plate with a triangular structure is provided on each side of the hinge ear plate and between it and the seat plate.
[0020] As an optimization, the door opening and closing control structure includes a door rotation limiting structure installed on the garbage bin to limit the rotation of the door, and the limiting connection end of the door rotation limiting structure can be detachably connected to the door; the door opening and closing control structure also includes a door rotation drive structure installed between the door and the garbage bin to control the vertical rotation of the door.
[0021] In this way, the design of the door opening and closing control structure is simpler and more reasonable, and both can better complete the opening and closing operation of the door.
[0022] As an optimization, the door rotation limiting structure includes upper locking plates mounted on both sides of the rear end of the garbage bin, each capable of vertical rotation via an mounting shaft. The rear end of the upper locking plate extends rearward to form a limiting hook with an opening facing downward, allowing the limiting hook to engage with a limiting post on the bin door to restrict the door from rotating and opening. A rotation limiting post is provided on the upper side of the mounting shaft on the garbage bin. A curved, arc-shaped elongated hole is provided on the upper locking plate corresponding to the rotation limiting post. The rotation limiting post is inserted into the elongated hole, allowing the upper locking plate to rotate vertically, and the rotation limiting post to abut against both ends of the elongated hole to restrict the locking plate from continuing to rotate. A hinged support plate extends upward from the upper side of the upper locking plate. The door rotation driving structure includes corresponding drive cylinders hinged to both sides of the upper end of the bin door, with the other end of the drive cylinder tilted downward and inward and hinged to the hinged support plate.
[0023] In this way, when the above structure is in operation, the drive cylinder rotates the upper locking plate, causing the limit hook to disengage from the limit post. It then continues to rotate the upper locking plate, allowing the limit post to engage with one end of the elongated hole, thus restricting further rotation of the upper locking plate. Afterward, the drive cylinder pushes the door to rotate and open. This allows the drive cylinder to sequentially operate the upper locking plate to unlock it. Once the upper locking plate is in a fixed position, the door can be rotated again to open it. The entire structure is simpler, with fewer components and a more streamlined and rational layout.
[0024] As an optimization, the door rotation limiting structure also includes lower locking plates installed on both sides of the rear end of the garbage bin, each of which can rotate vertically via an installation shaft. The rear end of the lower locking plate extends rearward to form a limiting hook with an opening facing downward, and the limiting hook can cooperate with the limiting post on the bin door to restrict the door from rotating and opening. The rear ends of the upper locking plate and the lower locking plate each extend rearward to form a protruding plate. A linkage rod is provided between the two protruding plates, and the two ends of the linkage rod are each hinged to the protruding plate via hinge joints.
[0025] In this way, by setting a lower locking plate, which is linked with the upper locking plate, the closing of the cabinet door can be made more stable and reliable.
[0026] As an optimization, a safety hook plate is hinged between the upper and lower locking plates on the trash can. The rear end of the safety hook plate forms a safety hook with an opening facing downwards, and the safety hook can cooperate with the safety post on the door to restrict the door from rotating and opening.
[0027] In this way, by setting a rear safety hook plate, when the cabinet door needs to be opened, the safety hook can be manually disengaged from the safety post, making the entire device more reliable.
[0028] In summary, the aforementioned garbage bin rear door unblocking device features a simpler and more reasonable structural design, can automatically unblock garbage at the rear of the garbage bin, and can better complete the unloading process. Attached Figure Description
