Abstract
Description
Technical Field
[0001] This invention relates to the field of waste treatment technology, and in particular to an auxiliary unloading device. Background Technology
[0002] Garbage collection and disposal typically involves transporting garbage bins via garbage trucks. However, the tops of these bins often protrude, causing garbage to easily fall during transport. Therefore, compression devices are needed to compact the garbage. Compressing garbage offers several advantages: firstly, it reduces the volume of garbage, saving space in bins or bags, extending their lifespan, reducing replacement frequency, and improving loading efficiency; secondly, it allows for more garbage to be loaded within the same capacity, increasing the loading efficiency of garbage trucks and reducing transportation costs; and thirdly, it facilitates processing: compressed garbage is easier to sort, process, and recycle, promoting resource reuse and recycling. However, with existing garbage trucks, residual garbage above the compression mechanism cannot be discharged through the rear of the bin. This residual garbage needs to be manually removed, increasing the workload of operators and being time-consuming, resulting in low unloading efficiency. Summary of the Invention

The feeding cylinder is disposed at the front end of the storage tank, and the feeding cylinder and the storage tank are connected through a feeding port disposed on the side wall of the feeding cylinder. The compression mechanism is disposed at the bottom of the feeding cylinder and is used to push the waste in the feeding cylinder into the storage tank for compression. The upper end of the movable partition is rotatably mounted on the upper end of the feeding port. When the movable partition rotates under gravity to be parallel to the side wall of the feeding cylinder, it can partially close the feeding port. A locking device is provided on the side wall of the feeding cylinder, and the locking device can fix the movable partition in a state parallel to the side wall of the feeding cylinder. The pushing device is installed inside the feeding cylinder and is convexly connected to the movable partition.

[0005] An auxiliary unloading device according to an embodiment of the present invention has at least the following beneficial effects: the compression mechanism pushes and compresses the waste in the feed cylinder into the storage tank. When tilting to pour out the waste, the locking device releases the fixation of the movable partition, and the movable partition rotates under the action of gravity to the open state, which can facilitate the discharge of residual waste in the feed cylinder through the upper opening. The function of the pushing device is to push the waste that is stuck or stuck in the feed cylinder into the feed inlet, thereby reducing the amount of residual waste in the feed cylinder.

[0035] Reference Figures 1 to 6As shown, an auxiliary unloading device according to an embodiment of the present invention includes: a storage tank 100, a feeding cylinder 200, a compression mechanism 300, a movable partition 400, and a pushing device 600. The storage tank 100 is a container installed on a garbage truck; its specific structure is prior art and will not be described in detail. The feeding cylinder 200 has an opening at its upper end to receive uncompressed garbage. The feeding cylinder 200 is located at the front end of the storage tank 100 and is fixed to the storage tank 100 by welding or bolts. The feeding cylinder 200 and the storage tank 100 are connected by a feeding port 210 located on the side wall of the feeding cylinder 200; the feeding port 210 is divided into an upper opening and a lower opening in the vertical direction. The compression mechanism 300 is located at the bottom of the feeding cylinder 200 and is used to push the garbage in the feeding cylinder 200 into the storage tank 100 for compression; the compression mechanism 300 is aligned with the lower opening, and pushes the garbage from the lower opening into the storage tank 100. The compression mechanism 300 compresses and stores waste in the storage box 100, effectively reducing the space occupied by waste and decreasing its volume, thus allowing more waste to be carried in a single transport and improving waste transportation efficiency. The upper end of the movable partition 400 is rotatably mounted on the upper end of the feed inlet 210. Under the action of gravity, the movable partition 400 rotates to a position parallel to the side wall of the feed cylinder 200, closing the upper opening. The movable partition 400 is used to close the upper opening when the compression mechanism 300 is working, leaving only the lower opening for feeding, preventing waste from flowing back into the feed cylinder 200 from the upper opening. A locking device 500 is provided on the side wall of the feed cylinder 200, which can fix the movable partition 400 in a position parallel to the side wall of the feed cylinder 200. When the storage box 100 tilts to dump waste, the locking device 500 releases the fixation of the movable partition 400, and the movable partition 400 rotates to an open position under the action of gravity, allowing residual waste in the feed cylinder 200 to be easily discharged through the upper opening. The pushing device 600 is installed inside the feed cylinder 200 and is connected to the movable partition 400 via a transmission mechanism. When the movable partition 400 rotates, it drives the pushing device 600 to push the waste in the feed cylinder 200 into the feed inlet 210. The function of the pushing device 600 is to push the waste that is stuck or stuck inside the feed cylinder 200 into the feed inlet 210, reducing the amount of waste remaining in the feed cylinder 200. The pushing device 600 is driven by the gravitational potential energy of the movable partition 400. It is foreseeable that the pushing device 600 is equipped with a manual crank, which can be used to operate the pushing device 600 when it is stuck by waste. During the garbage dumping process, the movable partition 400 rotates under its own weight and opens towards the side closer to the storage box 100. When dumping garbage, it pushes the garbage in the storage box 100 backward, which helps the garbage leave the storage box 100. The movable partition 400 opens the upper opening of the feed port 210, so that the residual garbage in the material cylinder can be discharged through the upper opening.
[0036] Reference Figures 1 to 2As shown, it can be understood that a discharge door 110 is provided on the side of the storage tank 100 away from the feed cylinder 200. The discharge door 110 is used to dump the waste in the storage tank 100. After the discharge door 110 is opened, the storage tank 100 is tilted backward by a hydraulic rod, and the waste will be discharged from the storage tank 100 under the action of gravity. The installation method and specific structure of the discharge door 110 are existing technologies, so they will not be described in detail.
[0037] Reference Figures 1 to 3 As shown, it can be understood that the compression mechanism 300 is a screw conveyor. Screw conveyors are highly adaptable and can be used for waste of various shapes and properties, including sticky and easily tangled waste such as kitchen waste and sludge. They can be fully automated, improving work efficiency. It is foreseeable that the compression mechanism 300 can also be selected from other devices capable of horizontally compressing waste.
[0038] Reference Figures 2 to 5 As shown, it can be understood that a counterweight 410 is provided at the lower end of the movable partition 400. The counterweight 410 is bolted to the lower end of the movable partition 400. Due to the obstruction of debris, the movable partition 400 will encounter resistance when opening. The greater the weight of the movable partition 400, the greater the gravitational force it experiences. Therefore, the counterweight 410 is provided to increase the gravitational force on the movable partition 400, thereby overcoming the resistance of the debris. Placing the counterweight 410 at the lower end of the movable partition 400, away from the axis of rotation of the movable partition 400, helps to increase the rotational torque of the movable partition 400.
[0039] Reference Figure 6 As shown, it can be understood that an insert plate 420 is provided on the side of the movable partition 400 near the feed cylinder 200, and the insert plate 420 is welded to the lower end of the movable partition 400. An insertion hole 421 is provided on the insert plate 420, and the insertion hole 421 is perpendicular to the direction of movement of the insert plate 420. The locking device 500 is a hydraulic push rod or an electric push rod, and the locking device 500 has a telescopic end. When compressing waste, the telescopic end extends into the insertion hole 421 to fix the movable partition 400, preventing waste from flowing back into the feed cylinder 200. When dumping waste, the telescopic end retracts, allowing the movable partition 400 to rotate freely and open its upper opening, allowing residual waste in the feed cylinder 200 to be discharged.
[0040] It is foreseeable that two sets of insert plates 420 and locking devices 500 are symmetrically arranged to more stably fix the movable partition 400.
[0041] Reference Figures 1 to 6As shown, both the telescopic end and the socket 421 are chamfered to guide the telescopic end during insertion into the socket 421. To ensure smooth and accurate insertion of the telescopic end into the socket 421, chamfers are designed on the edges of both the telescopic end and the socket 421. These chamfers play a crucial guiding role during insertion, helping to guide the telescopic end along the correct path, thereby reducing the possibility of friction and jamming, and ensuring the smoothness and stability of the entire telescopic process.
[0042] Reference Figures 1 to 6 As shown, it can be understood that the lowest point of the lower end of the movable partition 400 is equal to the upper end of the compression mechanism 300. This design ensures that the movable partition 400, when fixed, will not affect the compression mechanism 300's conveying of waste from the feed cylinder 200 to the storage bin 100. The entire waste conveying process will not be negatively affected by the presence of the movable partition 400.
[0043] Reference Figures 3 to 6 As shown, it can be understood that the pushing device 600 includes a transmission part 610 and a pushing plate 620. The lower end of the pushing plate 620 is mounted on the side wall of the feed cylinder 200 by rotation. Pushing shafts are provided on both sides of the lower end of the pushing plate 620. The pushing shafts pass through the bearing seats on the feed cylinder 200 to achieve rotational installation. The rotation axis of the pushing plate 620 is designed to be parallel to the rotation axis of the movable partition 400. Moreover, the height of the rotation axis of the pushing plate 620 is set to be higher than the rotation axis of the movable partition 400. The movable partition 400 has partition shafts on both sides at its lower end. The pusher shaft is rotatably mounted by passing through the bearing seat on the feed cylinder 200. When the movable partition 400 rotates, it can drive the pusher plate 620 to rotate together through the transmission part 610. Since the movement path of the pusher plate 620 passes through the upper area inside the feed cylinder 200, the rotation of the pusher plate 620 can push the garbage in the feed cylinder 200 towards the feed inlet 210, thereby achieving smooth garbage transportation.
[0044] Reference Figures 1 to 6 As shown, the transmission unit 610 is a gearbox, and a low-cost, easy-to-maintain gearbox is selected for the transmission unit 610. The partition shaft and the pusher shaft are connected to the input shaft and output shaft of the transmission unit 610 respectively via couplings. The rotational speed of the pusher plate 620 is greater than that of the movable partition 400. Since the tilt angle of the storage box 100 during unloading will not exceed 90 degrees, while the pusher plate 620 needs to rotate 180 degrees, the gearbox changes the transmission ratio to increase the rotation angle of the pusher plate 620. The rotation direction of the pusher plate 620 is the same as that of the movable partition 400.
[0045] Reference Figures 3 to 6As shown, it can be understood that an arc-shaped plate 621 is provided on the side of the pusher plate 620 away from the feed cylinder 200. When garbage is put into the feed cylinder 200, the arc-shaped plate 621 is located above the pusher plate 620 and tilted outward to guide the garbage entering the feed cylinder 200.
[0046] Reference Figures 1 to 6 As shown, a scraper 700 is rotatably mounted on the inner front wall of the feed cylinder 200. The axis of rotation of the scraper 700 is horizontal and parallel to the axis of rotation of the movable partition 400. When the compression mechanism 300 compresses the waste, the scraper 700 remains vertical under the action of gravity and will not affect the entry of the waste in the feed cylinder 200 into the storage tank 100. When dumping the waste, the scraper 700 rotates backward under the action of gravity, pushing the waste located in the lower half of the feed cylinder 200 into the storage tank 100.
[0047] Usage steps: The movable partition 400 is used to close the upper opening of the feed inlet 210 when the compression mechanism 300 is working. When the telescopic end extends into the insertion hole 421, it can fix the movable partition 400, leaving only the lower opening of the feed inlet 210 for feeding, preventing garbage from flowing back into the feed cylinder 200 from the upper opening. When the storage box 100 tilts to pour out garbage, the telescopic end of the locking device 500 retracts, releasing the fixation of the movable partition 400. Under the action of gravity, the movable partition 400 rotates to the state of opening the upper opening, which can conveniently discharge the residual garbage in the feed cylinder 200 through the upper opening. When the movable partition 400 rotates, it drives the pusher plate 620 to rotate together through the transmission part 610. Since the movement path of the pusher plate 620 passes through the upper area inside the feed cylinder 200, the pusher plate 620 can push the garbage in the upper part of the feed cylinder 200 towards the feed inlet 210 when it rotates. Under the action of gravity, the scraper 700 rotates backward to push the garbage in the lower part inside the feed cylinder 200 into the storage box 100.
[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
