Description
Technical Field
[0001] The utility model relates to the technical field of garbage collection and transfer, in particular to a garbage bin capable of compressing garbage. Background Art
[0002] Garbage transfer stations are usually set up at designated locations in each block and community to temporarily collect and store domestic waste, which is then regularly transferred to large-scale waste treatment stations or landfills for recycling or treatment through transfer equipment such as garbage transfer trucks. Existing garbage stations usually have multiple large garbage bins to collect garbage. Residents discard their domestic waste into the large garbage bins, and when the transfer truck arrives, the garbage in the large garbage bins is transferred to the transfer truck for transportation. In the above process, since the garbage is placed in a messy manner in the large garbage bins or transfer trucks, and the domestic garbage contains a large amount of fluffy materials, it will occupy a large space in the large garbage bins or transfer trucks, which to a certain extent affects the transfer collection capacity of the garbage station or the transportation capacity of the transfer truck, resulting in a shorter transfer cycle and a higher frequency of vehicle dispatch.
[0003] Furthermore, when designing and planning a garbage station, factors such as population size, per capita garbage generation, the station's transfer capacity, the traffic environment for garbage trucks, and the distance residents must travel to transport their garbage to the station must be fully considered. Existing large garbage stations use specialized, grippable, flip-top bins. When a transfer truck arrives, the bins can be gripped and the contents dumped into the truck, making operation more convenient. However, numerous small garbage stations (particularly those within residential communities where large transfer trucks cannot access) use conventional large garbage bins. To use the bins, a large garbage bag is placed inside. Upon arrival, the bag is removed and lifted up, then transferred to the truck for transport. This removal process is manual, and due to the large size and height of the bins, the bag contains a large amount of garbage, making removal extremely laborious. Due to this laborious operation, the bins should be kept small and low in height, which limits their collection capacity. Utility Model Content

DETAILED DESCRIPTION
[0027] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.
[0028] like Figures 1 to 7 As shown, a trash can for compressing garbage includes a barrel body 1, a rectangular cavity is provided in the barrel body 1, a feed port 2 is provided at the top of the barrel body 1, the feed port 2 is communicated with the top of the rectangular cavity, and a discharge port 3 is provided at one end of the lower part of the barrel body 1, the discharge port 3 is communicated with the rectangular cavity. It also includes a vertical pressure component and a horizontal pressure component. The vertical pressure component includes a feed bin 4, which is slidably adapted to be arranged in the upper part of the rectangular cavity, and the sliding direction of the feed bin 4 is along the vertical direction. A through hole with a gradually decreasing aperture from top to bottom is provided in the feed bin 4 along the vertical direction, and the through hole is arranged directly below the feed port 2; the horizontal pressure component includes a horizontal pressure plate 5, which is slidably adapted to be arranged in the lower part of the rectangular cavity, and the sliding direction of the horizontal pressure plate 5 is along the horizontal direction. The horizontal pressure plate 5 is arranged directly opposite the discharge port 3.
[0029] When the trash can with compressible garbage is in use, the initial position of the feed bin 4 is located in the middle of the upper area of the rectangular cavity, and the initial position of the horizontal pressure plate is located at the end of the lower area of the rectangular cavity away from the discharge port 3. When in use, it is divided into four action processes: bagging, collecting garbage, compressing garbage and taking out garbage.
[0030] When bagging, the bottom of the large garbage bag is passed through the through hole of the feed bin 4 from top to bottom, so that the bottom end of the large garbage bag extends out of the bottom end of the through hole, and the bag opening of the large garbage bag is opened and the edge is placed on the top edge of the through hole. Figures 2 to 5 As shown, the vertical cross-section of the through hole is trapezoidal, and the inclined surfaces on both sides are used to guide the garbage to fall. A surrounding edge 6 is provided at the top of the through hole for setting up the opening of the large garbage bag when bagging.
[0031] When collecting garbage, the garbage is thrown into the feed port 2, passes through the through hole of the feed bin 4, and then falls to the bottom of the rectangular cavity under its own weight. Since the garbage bag is put on according to the above process, the garbage falls into the large garbage bag. As the garbage falls, the bottom of the garbage bag can be driven to fall to the bottom of the barrel 1 (rectangular cavity) together with the garbage bag. The overall length of the large garbage bag is compatible with the garbage bin, and there is no pulling during the process of throwing garbage, causing the bag mouth to fall out. As the garbage is continuously thrown in, the large garbage bag below the feed bin 4 is gradually expanded until it is full and the collection is completed.
[0032] When compressing the garbage, the feed bin 4 is first raised. Since the bottom of the large garbage bag is full of garbage, it pulls the large garbage bag. During the rising process of the feed bin 4, the bag opening of the large garbage bag breaks away from the top edge of the through hole and gradually passes through the through hole downward (in this process, since the aperture of the through hole gradually decreases from top to bottom, the bag opening of the large garbage bag is also closed in the process. At the same time, the garbage located in the area near the bottom of the feed bin 4 lacks the constraint of the garbage bag and will spread to the surroundings to a certain extent, further stretching the bag body of the garbage bag in this area), until the bag opening of the large garbage bag passes through the bottom end of the through hole, the feed bin 4 stops rising, and the bag unloading process is completed at this time; thereafter, the feed bin 4 is lowered. During the lowering process, the bottom surface of the feed bin 4 can compress the large garbage bag filled with garbage below together with the garbage inside it, reducing its volume, until the feed bin 4 drops to the set height (near the top of the horizontal pressure plate 5).
[0033] When taking out the garbage, the horizontal pressing plate 5 is slid toward the discharge port 3. The compressed garbage together with the large garbage bag can be pushed out of the discharge port 3 under the push of the horizontal pressing plate 5, thereby completing the process of taking out the garbage.
[0034] As can be seen from the above, the compressible garbage bin has the function of compressing garbage and is convenient for removing garbage. During compression, the garbage is wrapped in a large garbage bag and compressed together. The compressed garbage becomes smaller in volume and can be easily transferred to the transfer vehicle, reducing the space occupied by the transfer vehicle and improving the transfer capacity of the transfer vehicle. After the garbage bin is full, the garbage can be easily removed, and the compressed garbage can be conveniently temporarily stacked outside the garbage bin. The garbage bin can be re-bagged and used, which can improve the transfer and collection capacity of the garbage station.
[0035] As mentioned above, the feed bin 4 is mainly used for bagging and compressing garbage. During the process of compressing garbage, as the feed bin 4 descends, the garbage is compressed by the bottom surface of the feed bin 4. The bottom end of the through hole is located at the bottom surface of the feed bin 4 and is hollow. In order to allow the input garbage to fall smoothly, the diameter of the through hole needs to be set larger. This means that the garbage at this position is not subjected to direct downward pressure during the compression process, which will affect the compression effect and even cause the large garbage bag to tear at this position during compression. To solve this problem, further, as Figures 3 to 5 As shown, the vertical pressure assembly also includes two vertical pressure plates 7, with a rectangular hole machined on the bottom surface of the feed bin 4, and a boss 8 is formed at the junction of the rectangular hole and the bottom end of the through hole. The two vertical pressure plates 7 are symmetrically arranged in the rectangular hole, and the symmetry lines of the two vertical pressure plates 7 are parallel and arranged directly above the center line of the sliding path of the horizontal pressure plate 5. The ends of the two vertical pressure plates 7 that are away from each other are rotatably connected to the feed bin 4. A torsion spring 10 is provided between the vertical pressure plates 7 and the feed bin 4. The torsion spring 10 is used to provide elastic force to press the vertical pressure plates 7 toward the boss 8. A gap 9 is left between the ends of the two vertical pressure plates 7 that are close to each other. The above-mentioned two vertical pressure plates 7 are similar to a double-door structure. Due to the provision of the boss 8, they can only be opened toward the bottom of the feed bin 4 and are naturally closed under the action of the torsion spring 10; the two vertical pressure plates 7 are arranged in the rectangular hole, and in the closed state, the lower side surfaces of the two vertical pressure plates 7 are flush with the bottom end of the feed bin 4. The above specific design has the following effects according to the four processes of bagging, collecting garbage, compressing garbage and taking out garbage:
[0036] During the bagging process, the bottom end of the large garbage bag extends through the gap 9 to the bottom of the feed bin 4. In actual operation, the vertical pressure plate 7 can be pushed downward to extend the bottom end of the large garbage bag to the set position below the feed bin 4. After the vertical pressure plate 7 rebounds under the action of the torsion spring 10, the bottom end of the large garbage bag is naturally located in the gap 9 between the two vertical pressure plates 7. The size of the gap 9 does not make the bagging operation difficult.
[0037] During the garbage collection process, the garbage thrown in can drive the vertical pressure plate 7 to flip open to the bottom of the feed bin 4 under the action of its own weight, and the thrown garbage can smoothly fall into the bottom of the garbage bag and drive the bottom of the garbage bag to move to the bottom of the barrel body 1.
[0038] During the garbage compression process, in the bag-removing stage when the feed bin 4 rises, the vertical pressure plate 7 is gradually closed under the action of the torsion spring 10, and the gap 9 between the two vertical pressure plates is gradually reduced, so that the bag opening of the large garbage bag can be gradually combed until the bag opening of the large garbage bag falls off from the smallest gap 9 when the vertical pressure plate 7 is in the closed state. At this time, the bag opening of the large garbage bag is close to a closed state; in the compression stage when the feed bin 4 descends, the vertical pressure plate 7 is in a closed state. At the bottom end of the through hole, the downward pressure when the feed bin 4 descends is transmitted to the vertical pressure plate 7 by the boss 8 to compress the garbage below, thereby avoiding the influence of the existing large-sized hollow area on the compression process, which is conducive to ensuring the compression effect.
[0039] During the process of removing the garbage, the vertical pressing plate 7 is in a closed state and its bottom side surface is flush with the lower bottom surface of the feed bin 4, which can avoid the horizontal pressing plate 5 from getting stuck when pushing out the garbage.
[0040] Furthermore, the vertical pressure assembly also includes a downward pressure drive device, which can be a hydraulic cylinder, an electric push rod, etc., to drive the feed bin 4 to rise and fall in the barrel 1 to complete the above-mentioned garbage compression process. In this embodiment, the downward pressure drive device uses a screw nut mechanism, such as Figure 6 As shown, the downward pressure driving device includes a screw rod 11, which is arranged in a vertical direction. The screw rod 11 is rotatably connected to the barrel body 1, and the screw rod 11 is threadedly connected to the feed bin 4. When the screw rod 11 is rotated, the feed bin 4 can be driven to rise and fall and slide; in the specific implementation, a lifting motor is also provided, and the lifting motor is used to drive the screw rod 11 to rotate to realize automatic control of the compression process.
[0041] Furthermore, the transverse pressure assembly also includes a transverse pressure driving device, which can also be selected from a variety of structural forms, such as a hydraulic cylinder, an electric push rod, etc., which is used to drive the transverse pressure plate 5 to slide horizontally in the barrel body 1. In this embodiment, Figure 2 、 Figure 6 As shown, the transverse pressure driving device includes a transmission shaft 12 and two chain transmission mechanisms, and the chain transmission mechanism includes a first sprocket 13, a second sprocket 14 and a chain 15, and the first sprocket 13 and the second sprocket 14 are connected by a chain 15; the transmission shaft 12 is rotatably arranged at one end of the lower part of the barrel body 1 away from the discharge port 3, and the transmission shaft 12 is perpendicular to the sliding path of the transverse pressure plate 5, and the two first sprockets 13 are fixedly connected to the two ends of the transmission shaft 12 respectively, and the two second sprockets 14 are rotatably connected to the barrel body 1, and the two ends of the transverse pressure plate 5 are fixedly connected to the two chains 15 respectively. When the transmission shaft 12 rotates, it can drive the two first sprockets 13 to rotate synchronously. Under the action of the chain transmission mechanism, the two chains 15 can drive the two ends of the transverse pressure plate 5 to move synchronously, thereby realizing the driving of the transverse pressure plate 5 to slide horizontally; in specific implementation, a transverse pressure motor can also be provided, which is used to drive the transmission shaft 12 to rotate, so as to realize automatic control of the garbage removal process.
[0042] Furthermore, a flap 16 is provided on the side of the discharge port 3 away from the rectangular cavity. The top of the flap 16 is rotatably connected to the barrel body 1. In its natural state, the flap 16 swings vertically under its own weight, closing the discharge port 3. The flap 16 can be designed to be heavy to shield the discharge port 3 and reduce the possibility of the lower area of large garbage bags being squeezed out of the discharge port 3 during the aforementioned garbage collection and compression process. During the aforementioned garbage removal process, the garbage can be pushed open by the horizontal pressure plate 5 to facilitate removal.
[0043] In this embodiment, a clamping assembly is also provided, which is used to provide elastic force to press the flap plate 16 toward the discharge port 3, so that the flap plate 16 remains in a compressed and closed state in a natural state, so as to further prevent the part located at the lower part of the large garbage bag from being squeezed out of the discharge port 3 during the aforementioned garbage collection and compression process. At the same time, in the process of taking out the garbage, the horizontal pressure plate 5 pushes the garbage to slide and can also achieve further horizontal compression of the garbage to a certain extent, until the clamping force of the compression assembly is overcome and the flap plate 16 is pushed open.
[0044] When implementing it specifically, Figure 7 As shown, the clamping assembly includes a sleeve 17, a telescopic rod 18 and a spring 19. One end of the sleeve 17 is rotatably connected to the barrel body 1, one end of the telescopic rod 18 is slidably arranged in the other end of the sleeve 17, and the other end of the telescopic rod 18 is rotatably connected to the flap plate 16. The two ends of the spring 19 are respectively connected to the sleeve 17 and the telescopic rod 18, thereby providing a clamping elastic force to the flap plate 16 through the spring 19, and the flipping and swinging of the flap plate 16 does not affect its use.
[0045] It should also be noted that, as previously mentioned, the installation of a lifting motor in the compressible trash bin enables automatic control of the compression process, and the installation of a horizontal pressing motor enables automatic control of the trash removal process. In subsequent research and development, a bag feeding and bag supporting mechanism can be installed above the trash bin in the garbage station to achieve automatic bagging. A conveyor belt can be installed outside the discharge port 3 in the garbage station to automatically transport the compressed and pushed-out garbage (bags), thus achieving automatic control of the entire process. Therefore, this compressible trash bin can also be used to realize the construction of intelligent and automated garbage stations.

It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant fields.
