Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to a combined feeding system. Background Technology

[0002] Currently, the two main feeding methods are commonly known for horizontal pre-compression garbage compactors.

[0003] The first type is the "high-platform feeding" system. This system mounts the compressor body on a ground foundation, but requires a two-story station building. Garbage collection vehicles must travel via a dedicated ramp to the second-floor platform, dumping garbage from above into the compressor's feeding inlet on the first floor. While this structure achieves a match between the feeding inlet and the truck hopper height, it also has significant drawbacks: First, the two-story station involves a large amount of civil engineering work, resulting in high construction costs and a long construction period; second, the ramp occupies a significant amount of valuable land, imposing stringent requirements on the transfer station's site selection and planning.

[0004] The second type is the "pit type." This method involves lowering the compressor body into an underground pit, making the feed inlet level with the ground. Collection vehicles can unload directly at ground level without needing to go uphill. However, this solution also has inherent drawbacks: First, the excavation and waterproofing of the deep pit are complex, resulting in extremely high civil engineering costs and difficulties. Furthermore, in areas with abundant rainfall or high groundwater levels, there is a risk of water accumulation in the pit and equipment submersion. Second, during unloading, an additional large lifting device is needed to raise the heavy machine or compressed waste blocks to ground level before handing them over to the transport vehicle. This leads to complex equipment structure, significantly increased energy consumption, and challenges to reliability. Therefore, a combined feeding system is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a combined feeding system, which aims to improve the complex excavation and waterproofing and seepage prevention engineering of deep foundation pits, which has extremely high civil engineering costs and difficulties, and in areas with abundant rainfall or high groundwater levels, there is a risk of water accumulation in the foundation pit and equipment submersion.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a combined feeding system, including a frame, a feeding mechanism at the front end of the frame, a pushing mechanism fixedly connected inside the frame, and a receiving bin inside the frame;

[0007] The feeding mechanism includes two boom shafts, both of which are rotatably connected to the outside of the frame. A hopper is rotatably connected to the end of each boom shaft away from the frame. A connecting rod shaft is rotatably connected to the outside of the hopper. The end of the connecting rod shaft away from the hopper is rotatably connected to the outside of the frame. A tilting shaft is fixedly connected between the two boom shafts. A tilting frame is fixedly connected between the two connecting rod shafts. A tilting cylinder is rotatably connected to the outside of the connecting rod shaft.

[0008] As a further description of the above technical solution:

[0009] A connecting rod is rotatably connected to the outside of the connecting rod shaft, and a boom cylinder is rotatably connected to the outside of the boom connecting shaft.

[0010] As a further description of the above technical solution:

[0011] The pushing mechanism includes a pushing box, which is fixedly connected to the inner wall of the pushing mechanism. Two nylon guide rails are fixedly connected inside the pushing box, and a telescopic hydraulic cylinder is fixedly connected to the inner wall of the pushing box. A pusher block is fixedly connected to the output end of the telescopic hydraulic cylinder.

[0012] As a further description of the above technical solution:

[0013] The top of the pusher block is rotatably connected to a first pusher cover plate, the top of the pusher block is rotatably connected to a second pusher cover plate, and the pusher block is slidably connected to the outer wall of the nylon guide rail.

[0014] As a further description of the above technical solution:

[0015] The frame has a receiving bin inside.

[0016] As a further description of the above technical solution:

[0017] The hopper and receiving bin are compatible.

[0018] As a further description of the above technical solution:

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, the solution does not require the construction of a double-layer station or a deep foundation pit. The feeding mechanism, the pushing mechanism and the receiving bin are supported by a frame. After the feeding mechanism receives the material on the ground, it lifts and flips the waste into the receiving bin. The pushing mechanism then pushes the waste into the compression box, which greatly reduces the civil engineering cost and construction difficulty, reduces the land occupation, and is suitable for urban areas with scarce land resources.

[0021] 2. In this utility model, the system relies on the cooperation of the feeding mechanism and the pushing mechanism to achieve automated feeding. The pusher cover can prevent garbage from falling behind the pusher and causing malfunctions. The garbage is transported in a closed space. There is no need for a high-power lifting device, which reduces energy consumption and equipment failure rate. It also reduces garbage scattering, improves the working environment, and improves the overall feeding efficiency. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 An embodiment of this utility model is provided: a combined feeding system, including a frame 1, a feeding mechanism 3 is provided at the front end of the frame 1, a pushing mechanism 2 is fixedly connected inside the frame 1, and a receiving bin 17 is opened inside the frame 1.

[0034] Frame 1 serves as the basic support structure for the entire combined feeding system, providing a stable mounting platform for the feeding mechanism 3, the pushing mechanism 2, and the receiving bin 17, ensuring that each component maintains a stable relative position during operation. The feeding mechanism 3 is located at the front end of frame 1 and can transport waste to the receiving bin 17 inside frame 1 after the waste is received on the ground. The pushing mechanism 2 is located inside frame 1 and is used to push the waste temporarily stored in the receiving bin 17 to the compression box of the subsequent compressor. The receiving bin 17 serves as a transition space between the feeding mechanism 3 and the pushing mechanism 2, realizing the temporary storage and transfer of waste.

[0035] Reference Figures 5-7 The feeding mechanism 3 includes two large arm connecting shafts 4, both of which are rotatably connected to the outside of the frame 1. A hopper 7 is rotatably connected to the end of the large arm connecting shaft 4 away from the frame 1. A connecting rod shaft 5 is rotatably connected to the outside of the hopper 7. The end of the connecting rod shaft 5 away from the hopper 7 is rotatably connected to the outside of the frame 1. A tilting shaft 10 is fixedly connected between the two large arm connecting shafts 4. A tilting frame 9 is fixedly connected between the two connecting rod shafts 5. A tilting cylinder 8 is rotatably connected to the outside of the connecting rod shaft 5.

[0036] The two boom shafts 4 are rotatably connected to the frame 1 and the hopper 7 to form a linkage structure, providing the main support for the lifting and lowering movement of the hopper 7. The connecting shaft 5 is rotatably connected to the frame 1 and the hopper 7, which can help stabilize the movement posture of the hopper 7 and prevent the hopper 7 from tilting during the lifting and lowering process. The tilting shaft 10 fixes the two boom shafts 4 to ensure that the two boom shafts 4 rotate synchronously, so that the force on both sides of the hopper 7 is balanced and the lifting and lowering is more stable. The tilting frame 9 fixes the two connecting shafts 5 to ensure that the movement of the connecting shafts 5 is synchronous, further improving the stability of the movement of the hopper 7. The tilting cylinder 8 can drive the hopper 7 to tilt around the relevant rotation point of the tilting frame 9 through its own extension and retraction action. When the hopper 7 rises to the corresponding height of the receiving bin 17, the tilting cylinder 8 extends and pushes the hopper 7 to tilt, dumping the internal garbage into the receiving bin 17.

[0037] Reference Figures 5-7The connecting rod shaft 5 is externally rotatably connected to the connecting rod 6, and the boom connecting shaft 4 is externally rotatably connected to the boom cylinder 18.

[0038] The connecting rod 6 connects between the two connecting rod shafts 5, which can enhance the synchronization of the movement of the two connecting rod shafts 5 and avoid the tilting of the hopper 7 due to the lag in the movement of the connecting rod shaft 5 on one side, ensuring that the hopper 7 always maintains a horizontal or preset posture during the lifting process; the boom cylinder 18, as the main power source of the feeding mechanism 3, drives the boom connecting shaft 4 to rotate around the rotation point with the frame 1 through the extension and retraction of its own piston rod, thereby driving the hopper 7 to rise from the ground receiving station to the unloading station corresponding to the receiving bin 17, or to descend from the unloading station back to the ground receiving station, realizing the lifting and lowering action control of the hopper 7.

[0039] Reference Figure 1 and Figure 8 The pushing mechanism 2 includes a pushing box 12, which is fixedly connected to the inner wall of the pushing mechanism 2. Two nylon guide rails 11 are fixedly connected inside the pushing box 12. A telescopic cylinder 13 is fixedly connected to the inner wall of the pushing box 12. A pusher block 16 is fixedly connected to the output end of the telescopic cylinder 13.

[0040] The pusher box 12 provides installation space and movement boundaries for the internal components of the pusher mechanism 2, limiting the range of movement of waste during the pushing process and preventing waste from scattering outside the pusher mechanism 2. Two nylon guide rails 11 are arranged parallel inside the pusher box 12 to guide the sliding of the pusher block 16, reduce the frictional resistance of the pusher block 16 during movement, and ensure that the pusher block 16 can move smoothly along the preset trajectory. The telescopic cylinder 13 serves as the power source of the pusher mechanism 2. When its piston rod extends or retracts, it can drive the pusher block 16 to slide along the nylon guide rail 11. When a certain amount of waste is stored in the receiving bin 17, the telescopic cylinder 13 extends and pushes the pusher block 16 forward, pushing the waste in the receiving bin 17 towards the compressor's compression box, completing the waste pushing action.

[0041] Reference Figure 8 The top of the pusher block 16 is rotatably connected to the first pusher cover plate 14, and the top of the pusher block 16 is rotatably connected to the second pusher cover plate 15. The pusher block 16 is slidably connected to the outer wall of the nylon guide rail 11.

[0042] The pusher block 16 can move stably under the drive of the telescopic cylinder 13 through a sliding connection with the nylon guide rail 11. The first pusher cover plate 14 and the second pusher cover plate 15 are rotatably connected and installed on the top of the pusher block 16. When the pusher block 16 pushes the garbage forward along the nylon guide rail 11, the garbage exerts a forward force on the two cover plates, causing the cover plates to unfold around the rotation point and cover the exposed area behind the pusher block 16, preventing the garbage from falling behind the pusher block 16 during the pushing process. When the pusher block 16 returns to its original position after pushing, the two cover plates fold and retract around the rotation point under the obstruction of the inner wall of the pusher box 12 or under their own gravity, and fit against the top of the pusher block 16. This avoids interference between the cover plates and the internal structure of the pusher box 12 when the cover plates are reset, ensuring that the pusher block 16 can return to its initial position smoothly, and fundamentally eliminating malfunctions such as mechanism jamming and cylinder overload caused by garbage accumulation behind the pusher block 16.

[0043] Reference Figure 1 The frame 1 has a receiving bin 17 inside.

[0044] The receiving bin 17 is located inside the frame 1, and its position corresponds to the hopper 7 of the feeding mechanism 3. It is used to receive the garbage dumped by the tipping of the hopper 7. During the entire feeding process, the receiving bin 17 can temporarily store garbage and wait for the pushing mechanism 2 to complete the previous pushing action before receiving new garbage, so as to avoid the conflict between the actions of the feeding mechanism 3 and the pushing mechanism 2 and ensure the continuous and orderly operation of the feeding system. At the same time, the spatial structure of the receiving bin 17 can play a certain role in organizing the garbage, so that the subsequent pusher block 16 can push the garbage to the compression box more efficiently.

[0045] Reference Figures 6-8 The hopper 7 and the receiving bin 17 are compatible.

[0046] The compatibility between hopper 7 and receiving bin 17 is mainly reflected in their size, position, and tilting trajectory. The opening size and shape of hopper 7 match the inlet size of receiving bin 17. Furthermore, the tilting angle and trajectory of hopper 7 driven by tilting cylinder 8 ensure that all the waste in hopper 7 falls into receiving bin 17 during the tilting process, preventing waste from spilling outside receiving bin 17 due to poor compatibility. This compatibility design avoids waste loss and scattering, reducing pollution to the surrounding environment, while ensuring that receiving bin 17 can fully receive the waste conveyed by hopper 7, providing a guarantee for the efficient pushing of subsequent pushing mechanism 2 and ensuring the material transfer efficiency of the entire feeding process.

[0047] Working principle: With frame 1 as the overall basic support structure, the garbage truck first dumps garbage into the hopper 7 of the feeding mechanism 3 at the front of frame 1. Then, the boom cylinder 18, which is the core power source of the feeding mechanism 3, actuates. Its piston rod extends and retracts, driving the boom connecting shaft 4, which is rotatably connected to the outside of frame 1, to rotate around the rotation point. This, in turn, causes the hopper 7, which is rotatably connected to the end of the boom connecting shaft 4 away from frame 1, to rise. During this process, the connecting rod shaft 5, which is rotatably connected to the outside of hopper 7, assists the boom connecting shaft 4 in stabilizing the movement posture of hopper 7 and preventing hopper 7 from tilting. The externally rotating connecting rod 6 further enhances the synchronicity of the movement of the two connecting rod shafts 5. Meanwhile, the tilting shaft 10, fixedly connected between the two boom connecting shafts 4, ensures the synchronous rotation of the two boom connecting shafts 4, and the tilting frame 9, fixedly connected between the two connecting rod shafts 5, ensures the synchronous movement of the two connecting rod shafts 5, jointly guaranteeing the smooth lifting and lowering of the hopper 7. When the hopper 7 rises to the height corresponding to the receiving bin 17 opened inside the frame 1, the externally rotating tilting cylinder 8 of the connecting rod shaft 5 actuates, driving the hopper 7 to tilt around the relevant rotation point of the tilting frame 9, emptying the contents of the hopper 7. All the waste is poured into the receiving hopper 17. Then, the tilting cylinder 8 retracts, causing the hopper 7 to return to its original position, and the boom cylinder 18 retracts, causing the hopper 7 to descend and reset to the ground receiving position. At the same time or shortly thereafter, the pushing mechanism 2, which is fixedly connected inside the frame 1, starts to work. The pushing box 12 inside the pushing mechanism 2 provides installation and movement space for each component. The telescopic cylinder 13, which is fixed to the inner wall of the pushing box 12, moves. Its output end drives the pusher block 16, which is fixedly connected to it, to slide along the two nylon guide rails 11 fixed inside the pushing box 12. The top of the pusher block 16 rotates. The first pusher cover plate 14 and the second pusher cover plate 15 are connected and unfold as the pusher block 16 moves forward, covering the exposed area behind the pusher block 16 to prevent garbage from falling in. Then, the garbage temporarily stored in the receiving bin 17 is pushed to the compression box of the subsequent compressor. After the pushing is completed, the telescopic cylinder 13 retracts and drives the pusher block 16 to reset along the nylon guide rail 11. The first pusher cover plate 14 and the second pusher cover plate 15 are folded and attached to the top of the pusher block 16 under the obstruction of the inner wall of the pusher box 12 or under their own gravity. This cycle realizes the automated feeding operation of the entire system.
