Description

Technical Field

[0001] This invention relates to the field of waste compression bin technology, and in particular to a lifting structure for the gate of a horizontally docking, split-type direct-pressure waste compression bin and the waste compression bin itself. Background Technology

[0002] The compression process of the existing horizontal docking split direct-pressure waste compactor is as follows: Figure 1 , 2 As shown, the garbage is fed into the garbage hopper 1', the lifting mechanism 3' of the garbage compression host 2' lifts the gate at the rear of the garbage compression box, and the horizontal compression pusher 4' pushes the garbage into the garbage compression box and compresses it. The garbage is compressed multiple times until the garbage compression box is full. Then the lifting mechanism lowers the gate, and other pushing, pulling or transporting equipment moves the garbage compression box away.

[0003] Depending on the specific waste compression mode, direct-pressure waste compression containers are typically mounted on a positioner (horizontal movement, vertical lifting, fixed ground rail, etc.). After waste compression is complete and the container gate closes, a push-pull mechanism (the main unit) is needed to push the container (full container) a distance away from the main unit to avoid obstructing main unit components and facilitate the flow to the next process. At this point, the waste mixed in at the rear of the container will be exposed. Usually, a small amount of easily separable waste is manually removed and then placed back into the main unit's inlet.

[0004] In actual operation, due to the complexity of waste composition, a large amount of clump-like and rope-like waste, as well as waste that is difficult to separate, such as leather products, densely woven textiles, and advertising banners, can get stuck on the outside of the waste bin gate, and cannot be easily separated manually. When waste gets stuck or hangs at the rear of the bin, it prevents the rear gate from closing, and the waste still does not easily detach automatically when the transport vehicle unloads at the terminal waste treatment plant. More importantly, waste stuck at the lower end of the gate can create gaps, leading to secondary spillage and leakage during waste compression during transport, causing environmental pollution. Summary of the Invention

[0005] This application provides a lifting structure for a horizontally docking direct-pressure waste compression container gate and a waste compression container, which solves the problem that existing horizontally docking direct-pressure waste compression container gate structures cause waste to get stuck between the gate and the waste compression container door frame, making it difficult to handle.

[0006] The first aspect of this application provides a lifting structure for a horizontally docking direct-pressure waste compression container gate, comprising:

[0007] A gate is slidably inserted into the rear of the waste compression container, and the gate has a protrusion facing outward.

[0008] The drive unit is connected to the waste compression box;

[0009] A mounting base is connected to the driving component, which drives the mounting base to move vertically.

[0010] The lower support plate is connected to the mounting base and is located below the protrusion. The lower support plate is used to push the protrusion upward under the drive of the driving member.

[0011] An upper pressure plate is connected to the mounting base and is located above the protrusion. The upper pressure plate is used to push the protrusion downward under the drive of the driving member.

[0012] The beneficial effects of the above embodiments are as follows: by improving the gate and adding a lower support plate and an upper pressure plate to the improved gate to drive the gate to move up and down, the staff can independently open and close the gate after the garbage compression box is separated from the garbage compression host, which makes it easier for the staff to clean up the garbage stuck between the gate and the garbage compression box frame.

[0013] Based on the above embodiments, the embodiments of this application can be further improved as follows:

[0014] In one embodiment of this application: there are two protrusions symmetrically arranged on both sides of the top of the gate, and the gate is slidably embedded in the door frame of the waste compression container unloading door. The beneficial effect of this step is that by providing protrusions on both sides of the gate, the gate can be evenly stressed on both sides, which helps to improve the stability of the gate's movement.

[0015] In one embodiment of this application: a connecting block is provided on the side of the gate away from the body of the garbage compression box, and the connecting block has a mating interface for cooperating with the gate lifting mechanism of the garbage compression host.

[0016] In one embodiment of this application, the system further includes: a guide seat connected to the waste compression container; and a guide rod slidably inserted into the guide seat, the sliding direction of which is consistent with the sliding direction of the gate. The guide rod is connected to both the driving component and the mounting base, and is used to drive the mounting base to move vertically under the drive of the driving component. The beneficial effect of this step is that the cooperation between the guide rod and the guide seat improves the stability of the mounting base's movement.

[0017] In one embodiment of this application, the system further includes: an elastic element disposed between the mounting base and the upper pressure plate, the elastic element driving the upper pressure plate to move upward toward the protrusion; a guide reset seat connected to the waste compression box and located directly below the upper pressure plate, the guide reset seat extending a protruding section toward the upper pressure plate, the upper end of the protruding section having a guide surface A; the upper pressure plate includes: a sliding portion slidably connected to the mounting base, the lower end of the sliding portion having a guide surface B in the direction toward the guide surface A, the guide surface B being an inclined surface, the guide surface B gradually tilting downward in the direction away from the lower support plate; and an upper pressing portion located above the sliding portion and relative to the sliding portion toward the protrusion. The sliding part extends a certain distance in the direction of the upper pressure plate. The sliding part has a positioning surface A in the direction of the lower support plate. The lower support plate is provided with a positioning surface B corresponding to the positioning surface A. The positioning surface A is used to cooperate with the positioning surface B so that the upper pressure plate is positioned at position A. At position A, the end of the upper pressure part is located directly above the lower support plate and forms a gap with the lower support plate. The protrusion is located in the gap. At this time, the upper pressure plate or the lower support plate can drive the protrusion to move up and down. When the gate descends to the point where the guide surface A contacts the guide surface B, the upper pressure part moves away from the protrusion until the upper pressure part moves away from directly above the protrusion. At this time, the upper pressure plate enters position B. The beneficial effects of this step are as follows: By setting up an elastic element, the upper pressure plate can be positioned at the lower support plate when the guide surface A and the guide surface B are not in contact. This allows the upper pressure plate to press down on the protrusion, causing the gate to move downwards until the gate closes. During this process, due to the cooperation between the guide surface B and the guide surface A, the upper pressure plate moves away from the protrusion, so that the upper pressure plate will not affect the opening and closing action of the gate in normal working condition.

[0018] In one embodiment of this application: the guide surface A is an arc surface, the guide surface B is a plane, and a transition surface, which is an arc surface, is provided between the guide surface B and the positioning surface A. The beneficial effect of this step is that the transition from the arc surface to the plane, and then to the contact between two arc surfaces, makes the movement of the upper pressure plate more stable.

[0019] In one embodiment of this application, it further includes: a limiting member connected to the side of the sliding part, the sliding part being slidably inserted into a corresponding groove in the mounting base, the side of the mounting base having a limiting hole communicating with the groove, and the limiting member being intermittently inserted into the limiting hole. The beneficial effect of this step is that when the protrusion applies pressure upwards to the upper pressure plate, the pressure direction is perpendicular to the elastic force generated by the elastic element. Therefore, the upper pressure plate will not move in the direction of compressing the elastic element. The rotation tendency of the upper pressure plate is limited by the cooperation of positioning surface A and positioning surface B, and the cooperation of the limiting member and the limiting hole, preventing the upper pressure plate from rotating under pressure. That is, the upper pressure plate cannot rotate or displace, so the positioning of the upper pressure plate is very stable. The stable positioning of the upper pressure plate can not only stably drive the gate to close, but also, due to the surface contact structure of positioning surface A and positioning surface B, the pressure at the contact point is small during the limiting process, thus protecting the components and improving their service life.

[0020] In one embodiment of this application, it further includes: a connecting seat A, connected to the garbage compression box, the connecting seat A also being connected to the driving component; and a connecting seat B, connected to the guide rod and disposed above the connecting seat A, the connecting seat B also being connected to the driving component.

[0021] In one embodiment of this application: the driving component is a hydraulic cylinder; the hydraulic cylinder is connected to a hydraulic quick connector A via a hydraulic pipeline; or the hydraulic cylinder is connected to the oil circuit of the garbage compression box unloading door locking cylinder via a three-way valve.

[0022] A second aspect of this application provides a waste compression container, including a lifting structure for the gate of the horizontally docked direct-pressure waste compression container. Attached Figure Description

[0051] Example 1

[0052] like Figure 3 , 4 As shown in Figure 5, a lifting structure for a horizontally docking direct-pressure garbage compression container gate 1 includes: a gate 1, a drive component 2, a mounting base 3, a lower support plate 4, and an upper pressure plate 5. The gate 1 is slidably inserted into the tail of the garbage compression container 6. The gate 1 has a protrusion 101 facing outward. The drive component 2 is connected to the garbage compression container 6. The mounting base 3 is connected to the drive component 2. The drive component 2 is used to drive the mounting base 3 to move vertically. The lower support plate 4 is connected to the mounting base 3 and is located below the protrusion 101. The lower support plate 4 is used to push the protrusion 101 upward under the drive of the drive component 2. The upper pressure plate 5 is connected to the mounting base 3 and is located above the protrusion 101. The upper pressure plate 5 is used to drive the protrusion 101 downward under the drive of the drive component 2.

[0053] like Figure 3 As shown, there are two protrusions 101 symmetrically arranged on both sides of the top of the gate 1, and the gate 1 is slidably embedded in the door frame 7 of the unloading door of the garbage compression box 6.

[0054] like Figure 3 As shown, specifically, the unloading gate is composed of a door frame 7 and a gate 1. One side of the door frame 7 is hinged to the rear of the garbage compression box 6, and the other side is locked by a locking mechanism 8. The door frame 7 is equipped with an opening that communicates with the inside of the box. Guide grooves 701 are symmetrically arranged on both sides of the opening. The gate 1 is slidably inserted into the guide grooves 701. The gate 1 is used to control the opening and closing of the opening.

[0055] like Figure 3 As shown, a connecting block 102 is provided on the side of the gate 1 away from the garbage compression box 6. The connecting block 102 has a mating interface 103, which is used to cooperate with the lifting mechanism of the garbage compression host. The lifting mechanism is used to drive the gate 1 to open or close.

[0056] like Figure 3 As shown, specifically, a baffle 702 is provided in the middle of the door frame 7 along the horizontal direction. The connecting block 102 is located above the baffle 702. When the lower end of the connecting block 102 contacts the baffle 702, the gate 1 is in the lowest position. At this time, the lower edge of the gate 1 is completely blocked by the cover plate 703 at the lower opening of the door frame 7, so that the opening is closed by the gate 1.

[0057] like Figure 3 As shown, this lifting structure also includes: a guide seat 9 and a guide rod 10. The guide seat 9 is connected to the garbage compression box 6, and the guide rod 10 is slidably inserted in the guide seat 9. The sliding direction of the guide rod 10 is consistent with the sliding direction of the gate 1. The guide rod 10 is connected to the driving component 2 and the mounting seat 3 respectively. The guide rod 10 is used to drive the mounting seat 3 to move vertically under the drive of the driving component 2.

[0058] like Figure 3 As shown, specifically, guide seats 9 and guide rods 10 are connected to the outer surfaces of both sides of the door frame 7. Taking one side of the door frame 7 as an example, two guide seats 9 are connected vertically and spaced apart from each other. The guide seats 9 have guide holes opened vertically. The guide holes are through holes. The two guide holes are concentric and the center is parallel to the sliding direction of the gate 1. The guide rod 10 is slidably inserted into the guide hole. The upper end of the guide rod 10 is connected to the mounting base 3. The power of the driving component 2 is transmitted by the guide rod 10, thereby driving the lower support plate 4 and the upper pressure plate 5 to move vertically.

[0059] like Figure 4 , 5As shown in Figure 6, this lifting structure further includes: an elastic element 11 and a guide reset seat 12. The elastic element 11 is disposed between the mounting base 3 and the upper pressure plate 5. The elastic element 11 is used to drive the upper pressure plate 5 to move upward toward the protrusion 101. The guide reset seat 12 is connected to the garbage compression box 6 and is located directly below the upper pressure plate 5. The guide reset seat 12 extends a protrusion 1201 toward the upper pressure plate 5. The upper end of the protrusion 1201 has a guide surface A1202. The upper pressure plate 5 includes: a sliding part 501 and an upper pressing part 502. The sliding part 501 is slidably connected to the mounting base 3. The lower end of the sliding part 501 is provided with a guide surface B503 toward the guide surface A1202. The guide surface B503 is an inclined surface. The guide surface B503 gradually slopes downward in the direction away from the lower support plate 4. The upper pressing part 502 is located above the sliding part 501 and relative to the sliding part 501. The sliding part 501 extends a certain distance towards the protrusion 101 and has a positioning surface A504 in the direction of the lower support plate 4. The lower support plate 4 is provided with a positioning surface B401 corresponding to the positioning surface A504. The positioning surface A504 is used to cooperate with the positioning surface B401 so that the upper pressure plate 5 is positioned at position A. At position A, the end of the upper pressure part 502 is located directly above the lower support plate 4 and forms a gap with the lower support plate 4. The protrusion 101 is located in the gap. At this time, the upper pressure plate 5 or the lower support plate 4 can drive the protrusion 101 to move up and down. When the gate 1 descends to the point where the guide surface B503 contacts the guide surface A1202 and the guide surface B503 is guided to move by the guide surface A1202, the upper pressure part 502 moves away from the protrusion 101 until the upper pressure part 502 moves away from the protrusion 101. At this time, the upper pressure plate 5 enters position B.

[0060] like Figure 6 As shown, specifically, the lower support plate 4 has an L-shaped structure. The lower support plate 4 includes a vertical side and a horizontal side located at the lower end of the vertical side and arranged in a horizontal direction. The horizontal side extends in a direction away from the mounting base 3. The vertical side is connected to the end of the mounting base 3 facing the corresponding protrusion 101. The surface of the vertical side facing the positioning surface A504 is the positioning surface B401. The horizontal side is used to push the protrusion 101 to move upward. A gap is formed between the horizontal side and the upper pressing part 502 to insert the protrusion 101. The thickness of the protrusion 101 is less than the gap spacing.

[0061] like Figure 4 As shown, the lifting structure also includes a limiting member 13, which is connected to the side of the sliding part 501. The sliding part 501 is slidably inserted into the corresponding groove 301 of the mounting base 3. The side of the mounting base 3 is provided with a limiting hole 302 that communicates with the groove 301. The limiting member 13 is intermittently inserted into the limiting hole 302.

[0062] like Figure 4As shown, specifically, the slide groove 301 is symmetrically provided on both sides of the mounting base 3. The slide groove 301 is arranged in the horizontal direction. There are two limiting members 13, which are arranged in the horizontal direction at intervals and connected to the sliding part 501. The end of the limiting member 13 extends into the slide groove 301. The sliding part 501 is limited by the limiting member 13, so that the upper pressure plate 5 slides in the horizontal direction.

[0063] like Figure 6 As shown, guide surface A1202 is an arc surface, guide surface B503 is a plane, and a transition surface, which is an arc surface, is provided between guide surface B503 and positioning surface A504.

[0064] Specifically, when the planar guide surface B503 moves along the arc-shaped guide surface A1202, there is no contact with the angular structure. Until the transition surface contacts the guide surface A1202, the contact is still between the arc surfaces. On the one hand, this can improve the stability of the movement of the upper pressure plate 5, and on the other hand, it can reduce the wear between the contact surfaces.

[0065] like Figure 4 As shown, the mounting base 3 includes: a base body 303 and an end cap 304. The end cap 304 is connected to the end of the base body 303 away from the protrusion 101. The end cap 304 is provided with a boss A305 facing the slide groove 301. The sliding part 501 is provided with a boss B505 facing the boss A305. The elastic element 11 is a cylindrical compression spring. The two ends of the cylindrical compression spring are respectively sleeved on the outside of the corresponding boss A305 and boss B505, thereby stably positioning the elastic element 11 between the mounting base 3 and the upper pressure plate 5, and finally realizing the function of controlling the position of the upper pressure plate 5 by the elastic element 11 in conjunction with the protrusion 1201.

[0066] Specifically, by bonding the positioning surface A504 and the positioning surface B401 to form a surface contact positioning structure, the upper pressure plate 5 can be initially positioned on the lower support plate 4. The surface contact structure can reduce the pressure at the contact point. At the same time, the limiting member 13 in the slide groove 301 provides a common limiting effect on the upper pressure plate 5, which can stably position the upper pressure plate 5 above the lower support plate 4. This allows the upper pressure plate 5 to stably drive the gate 1 to move downward. Since the gate 1 will be resisted by the garbage during the downward movement, the positioning stability of the upper pressure plate 5 is very important. Stable positioning can determine the stability of the gate 1's movement. In addition, the surface contact structure can improve the service life of the structure by reducing the pressure.

[0067] Specifically, when guide surface A1202 and guide surface B503 are not in contact, the upper pressure plate 5 will remain in position A. During this process, when the mounting base 3 is driven to rise by the drive component 2, the lower support plate 4 will hold the lower end of the protrusion 101 and drive the gate 1 to move upward, thus realizing the opening action of the gate 1. When the mounting base 3 is driven to fall by the drive component 2, the upper pressure plate 5 will press the upper end of the protrusion 101 and drive the gate 1 to move downward, thus realizing the closing action of the gate 1. When guide surface B503 begins to contact guide surface A1202, the upper pressure plate 5 will move away from the protrusion 101 until the upper pressure plate 5 is no longer in contact with the protrusion 101. At this time, the upper pressure plate 5 enters position B, and the gate 1 is also closed at the same time. After the upper pressure plate 5 moves away from the protrusion 101, the gate 1 can be opened and closed normally by the lifting mechanism of the garbage compactor.

[0068] like Figure 3 As shown, the lifting structure also includes: a connecting seat A14 and a connecting seat B15. The connecting seat A14 is connected to the garbage compression box 6 and is also connected to the driving component 2. The connecting seat B15 is connected to the guide rod 10 and is located above the connecting seat A14. The connecting seat B15 is also connected to the driving component 2.

[0069] like Figure 3 As shown, specifically, the driving component 2 is a hydraulic cylinder, the connecting seat A14 is connected to the outside of the door frame 7, the cylinder body of the driving component 2 is connected to the connecting seat A14, the connecting seat B15 is located between the two guide seats 9 and connected to the outside of the guide rod 10, and the upper end of the piston rod of the hydraulic cylinder is connected to the connecting seat.

[0070] When a large amount of difficult-to-separate garbage is trapped at the lower end of gate 1, the mounting base 3 is driven to rise by the drive component 2. At this time, the lower support plate 4 moves upward and pushes gate 1 upward a distance K (20-200mm) on both sides of gate 1 before stopping. Because household garbage is sticky, the rise of gate 1 by K distance is insufficient to cause the garbage in garbage compression box 1 to bounce out. At this time, the staff can push the garbage protruding from below the gate into the garbage box, or pull it out, cut it, etc., until it is ensured that no garbage leaks out through the gap between gate 1 and the lower stop of door frame 7. At this time, since the guide reset seat 12 has separated from the upper pressure plate 5, the upper pressure plate 5 has moved to position A under the action of elastic component 11. Then, the mounting base 3 is driven down by the drive component 2, and the upper pressure plate 5 presses down on the gate 1, driving the gate 1 to close. When the guide surface B503 contacts the guide surface A1202, the upper pressure plate 5 continues to move away from the protrusion 101 until the upper pressure plate 5 separates from the protrusion 101. At this time, the upper pressure plate 5 moves to position B, and at the same time, the gap between the lower end of the gate 1 and the lower opening of the door frame 7 is eliminated, the gate 1 is closed, and the upper pressure plate 5 moves away from the protrusion 101. This lifting structure can adopt multiple lifting measures according to the actual situation on site until the mixed garbage is completely cleaned up. Even if the gate 1 cannot be completely pressed down, the gate 1 can be reset by the lifting mechanism when the gate 1 is connected to the garbage compression host.

[0071] The lifting structure of the gate 1 of this horizontal docking direct pressure garbage compression box allows the garbage mixed between the gate 1 and the door frame 7 to be processed at the source. That is, after the garbage compression box 6 is separated from the garbage compression host and before it is transferred (not transferred), the gate 1 can be opened by the drive component 2, which makes it easier for staff to handle the mixed garbage, avoids the garbage from being spilled during the transfer, and also avoids the trouble of cleaning the back door of the vehicle when unloading at the terminal garbage treatment plant.

[0072] Example 2

[0073] like Figure 7 As shown, the hydraulic cylinder is connected to the hydraulic quick connector A16 via a hydraulic pipeline.

[0074] This embodiment further discloses the hydraulic principle scheme of the lifting structure based on Embodiment 1. That is, a set of hydraulic quick connectors A16 is configured separately for use only by the drive component. The hydraulic power unit of the garbage compactor can be directly utilized, or a small mobile hydraulic power unit can be configured separately. In use, the quick connector of the hydraulic power hose on the external hydraulic power unit can be directly connected to the hydraulic quick connector A16 of the drive component.

[0075] Example 3

[0076] like Figure 8As shown, the hydraulic cylinder is connected to the oil circuit of the garbage compression box unloading door locking cylinder through a three-way valve 17. The three-way valve 17 is a manual three-way hydraulic ball valve.

[0077] This embodiment further discloses the hydraulic principle scheme of the lifting structure based on the first embodiment. That is, it shares a set of hydraulic quick connectors with the locking cylinder of the locking mechanism of the unloading gate. The flow direction of hydraulic oil in the hydraulic circuit is controlled by a manual three-way hydraulic ball valve. There are two working states: state one: the unloading gate and the gate open and close at the same time; state two: only the gate opens and closes.
