Description

Technical Field

[0001] The invention relates to the technical field of garbage disposal, and in particular to an auxiliary unloading device. Background Art

[0002] Garbage collection and treatment generally involves the use of garbage transfer trucks to transport garbage cans loaded with garbage. However, there is often a phenomenon of accumulation and protrusion on the top of the garbage can, which makes it easy for the garbage to fall during the transportation process. Therefore, a compression device is needed to compress the garbage. By compressing the garbage, on the one hand, the volume of the garbage can can be reduced, thereby saving the use space of the garbage can or garbage bag, extending the service life, reducing the frequency of replacement, and improving the loading efficiency. On the other hand, after compressing the garbage, more garbage can be loaded under the same capacity, which improves the loading efficiency of the garbage transfer truck and reduces the transportation cost. On the third hand, it is convenient to handle: the compressed garbage is easier to classify, process and recycle, which is conducive to the reuse and recycling of resources. However, when the existing garbage trucks dump garbage, the residual garbage above the compression mechanism cannot be discharged through the back of the garbage bin. This part of the garbage needs to be manually cleaned out, which increases the workload of the user, and manual cleaning takes a long time, resulting in low efficiency of garbage unloading.

[0022] Reference Figures 1 to 6As shown, an auxiliary unloading device of an embodiment of the present invention comprises: a storage box 100, a feed barrel 200, a compression mechanism 300, a movable partition 400, and a pushing device 600. The storage box 100 is a box body installed on a garbage truck, and its specific structure is the prior art, so it is not described in detail. The upper end of the feed barrel 200 is open to receive uncompressed garbage. The feed barrel 200 is arranged at the front end of the storage box 100, and the feed barrel 200 and the storage box 100 are fixed by welding or bolting. The feed barrel 200 and the storage box 100 are connected through a feed port 210 arranged on the side wall of the feed barrel 200; the feed port 210 is divided into an upper port and a lower port in the up and down direction, and the compression mechanism 300 is arranged at the bottom of the feed barrel 200, which is used to push the garbage in the feed barrel 200 into the storage box 100 for compression; the position of the compression mechanism 300 is aligned with the position of the lower port, and the compression mechanism 300 pushes the garbage from the lower port into the storage box 100. The compression mechanism 300 compresses and stores the garbage in the storage box 100, which can effectively reduce the space occupied by the garbage and reduce the volume, so that more garbage can be carried in one transportation, thereby improving the efficiency of garbage transportation. The upper end of the movable partition 400 is rotatably installed on the upper end of the feed port 210. The movable partition 400 can close the upper port when it rotates to be parallel to the side wall of the feed barrel 200 under the action of gravity. The movable partition 400 is used to close the upper port when the compression mechanism 300 is working, leaving only the lower port for feeding, to prevent the garbage from flowing back to the feed barrel 200 from the upper port. The side wall of the feed barrel 200 is provided with a locking device 500, which can fix the movable partition 400 in a state parallel to the side wall of the feed barrel 200; when the storage box 100 is tilted to pour out the garbage, the locking device 500 releases the fixation of the movable partition 400, and the movable partition 400 rotates to the state of opening the upper port under the action of gravity, so that the residual garbage in the feed barrel 200 can be easily discharged through the upper port. The pushing device 600 is installed in the feed barrel 200. The pushing device 600 is connected to the movable partition 400 by transmission. When the movable partition 400 rotates, it can drive the pushing device 600 to push the garbage in the feed barrel 200 into the feed port 210. The function of the pushing device 600 is to push the garbage adhered or stuck in the feed barrel 200 into the feed port 210 to reduce the garbage remaining in the feed barrel 200. The pushing device 600 is driven by the gravitational potential energy of the movable partition 400. It is foreseeable that a manual rocker is provided on the pushing device 600, and the pushing device 600 can be operated by the manual rocker when the pushing device 600 is stuck by garbage. During the process of dumping garbage, the movable partition 400 rotates by its own weight and opens toward the side close to the storage box 100, pushing the garbage in the storage box 100 backwards when dumping garbage, which is beneficial for the garbage to leave the storage box 100. The movable partition 400 opens the upper opening of the feed port 210, so that the remaining garbage in the barrel can be discharged through the upper opening.

[0023] Reference Figure 1 to Figure 2As shown, it can be understood that a discharge door 110 is provided on one side of the storage box 100 away from the feed cylinder 200, and the discharge door 110 is used to dump the garbage in the storage box 100. After the discharge door 110 is opened, the storage box 100 is driven to tilt backward by a hydraulic rod, and the garbage will be discharged from the storage box 100 under the action of gravity. The installation method and specific structure of the discharge door 110 are prior art, so they are not described in detail.

[0024] Reference Figures 1 to 3 As shown, it can be understood that the compression mechanism 300 is a screw conveyor. The screw conveyor has strong adaptability and can be used for garbage of various shapes and properties, including sticky and easily entangled garbage, such as kitchen waste, sludge, etc., and can be fully automated to improve work efficiency. It is foreseeable that the compression mechanism 300 can also use other devices that can compress garbage horizontally.

[0025] Reference Figures 2 to 5 As shown, it can be understood that a counterweight block 410 is provided at the lower end of the movable partition 400. The counterweight block 410 is bolted to the lower end of the movable partition 400. Due to the obstruction of garbage, the movable partition 400 will encounter resistance when it is opened, and the greater the weight of the movable partition 400, the greater the gravity it receives. Therefore, the counterweight block is provided to increase the gravity received by the movable partition 400, thereby overcoming the resistance of the garbage. The counterweight block is provided at the lower end of the movable partition 400, away from the rotation axis of the movable partition 400, which is conducive to increasing the rotation torque of the movable partition 400.

[0026] Reference Figure 6 As shown, it can be understood that a plug plate 420 is provided on one side of the movable partition 400 close to the feed barrel 200, and the plug plate 420 is welded to the lower end of the movable partition 400. A plug hole 421 is provided on the plug plate 420, and the plug hole 421 is perpendicular to the movement direction of the plug plate 420. The locking device 500 uses a hydraulic push rod or an electric push rod, and the locking device 500 has a telescopic end. When compressing garbage, the telescopic end can fix the movable partition 400 when it extends into the plug hole 421 to prevent the garbage from flowing back into the feed barrel 200. When dumping garbage, the telescopic end retracts, the movable partition 400 can rotate freely, and the movable partition 400 opens the upper mouth to discharge the residual garbage in the feed barrel 200.

[0027] It is foreseeable that two groups of the plug plates 420 and the locking devices 500 are symmetrically arranged to more stably fix the movable partition 400.

[0028] Reference Figures 1 to 6As shown, it can be understood that both the telescopic end and the plug hole 421 are provided with chamfers to play a guiding role in the process of inserting the telescopic end into the plug hole 421. In order to ensure that the telescopic end can be smoothly and accurately inserted into the plug hole 421, chamfers are designed on the edges of the telescopic end and the plug hole 421. These chamfers play an important guiding role in the process of the telescopic end inserting into the plug hole 421, helping to guide the telescopic end to move along the correct path, thereby reducing the possibility of friction and jamming, and ensuring the smoothness and stability of the entire telescopic process of the telescopic end.

[0029] Reference Figures 1 to 6 As shown, it can be understood that the height of the lowest point of the lower end of the movable partition 400 is equal to the height of the upper end of the compression mechanism 300. Such a design ensures that the movable partition 400 will not affect the compression mechanism 300 in conveying the garbage in the feed barrel 200 to the storage box 100 when it is fixed. The entire garbage conveying process will not be negatively affected by the existence of the movable partition 400.

[0030] 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 barrel 200 in a rotatable manner. Pushing shafts are arranged on both sides of the lower end of the pushing plate 620. The pushing shafts pass through the bearing seat on the feed barrel 200 to realize rotatable installation. The rotation axis of the pushing plate 620 is designed to remain parallel to the rotation axis of the movable partition 400. Not only that, the height of the rotation axis of the pushing plate 620 is also set to be higher than the rotation axis of the movable partition 400. The movable partition 400 is provided with partition shafts on both sides of the lower end, and the push shaft passes through the bearing seat on the feed barrel 200 to realize rotational installation. When the movable partition 400 is rotating, it can drive the push plate 620 to rotate together through the transmission effect of the transmission part 610. Since the movement path of the push plate 620 passes through the upper area in the feed barrel 200, the push plate 620 can push the garbage in the feed barrel 200 to the feed port 210 when it rotates, so as to realize the smooth transportation of garbage.

[0031] Reference Figures 1 to 6 As shown, it can be understood that the transmission part 610 is a gearbox, and the transmission part 610 uses a gearbox with low cost and easy maintenance. The partition shaft and the pusher shaft are respectively connected to the input shaft and the output shaft of the transmission part 610 through a coupling, and the rotation speed of the pusher plate 620 is greater than the rotation speed of the movable partition 400. Since the inclination angle of the storage box 100 will not exceed 90 degrees during unloading, and the pusher plate 620 needs to rotate 180 degrees. Therefore, the transmission ratio is changed through the gearbox to increase the rotation angle of the pusher plate 620. The rotation direction of the pusher plate 620 is the same as the rotation direction of the movable partition 400.

[0032] Reference Figures 3 to 6As shown, it can be understood that a curved plate 621 is provided on one side of the push plate 620 away from the feed barrel 200. When garbage is thrown into the feed barrel 200, the curved plate 621 is located above the push plate 620 and tilted outwards to guide the garbage entering the feed barrel 200.

[0033] Reference Figures 1 to 6 As shown, it can be understood that a scraper 700 is rotatably mounted on the inner wall of the front side of the feed barrel 200, and the rotation axis of the scraper 700 is horizontally arranged and parallel to the rotation axis of the movable partition 400. When the compression mechanism 300 compresses the garbage, the scraper 700 remains in a vertical state under the action of gravity, and will not affect the garbage in the feed barrel 200 from entering the storage box 100. When dumping the garbage, the scraper 700 rotates backward under the action of gravity to push the garbage located in the lower half of the feed barrel 200 into the storage box 100.

[0034] Usage steps: The movable baffle 400 is used to close the upper opening of the feed port 210 when the compression mechanism 300 is working. When the telescopic end is extended into the insertion hole 421, the movable baffle 400 can be fixed, leaving only the lower opening of the feed port 210 for feeding, preventing garbage from flowing back into the feed barrel 200 from the upper opening. When the storage box 100 is tilted to pour out the garbage, the telescopic end of the locking device 500 retracts to release the fixation of the movable baffle 400. The movable baffle 400 rotates to the state of opening the upper opening under the action of gravity, and the residual garbage in the feed barrel 200 can be conveniently discharged through the upper opening. When the movable baffle 400 rotates, the movable baffle 400 drives the push plate 620 to rotate together through the transmission part 610. Since the movement path of the push plate 620 passes through the upper area inside the feed barrel 200, the push plate 620 can push the garbage in the upper half of the feed barrel 200 toward the feed port 210 when it rotates. The scraper 700 rotates backward under the action of gravity to push the garbage in the lower half of the feed barrel 200 into the storage box 100.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
