Description

Technical Field

[0001] This utility model relates to the technical field of waste treatment equipment, and in particular to a dual-compression-chamber pressure head sliding waste compressor. Background Technology

[0002] In the process of transferring waste, waste transfer stations need to compress and reduce the volume of collected loose waste to improve transfer efficiency. Existing waste compressors have only one compression chamber for both feeding and compression. Feeding cannot occur during the compression process; the compression head must retract after the compression is complete before subsequent feeding can begin. This excessively long waiting time significantly reduces the efficiency of waste collection, compression, and transfer, hindering the large-scale implementation of pre-compression waste compression stations and making it difficult to accurately control the volume and weight of each waste block. Utility Model Content

[0003] The purpose of this invention is to provide a dual-compression-chamber sliding-head garbage compressor, thereby overcoming the shortcomings of existing compressors that only have one compression chamber, resulting in excessively long material waiting time and significantly reduced efficiency in garbage collection, compression, and transfer.

[0004] To achieve the above objectives, this utility model provides a dual-compression-chamber sliding-head garbage compactor, comprising: a compression chamber containing two compression chambers distributed along a front-to-back direction, each compression chamber having an opening at its top, and the two compression chambers being separated by a first gate, which is opened and closed by a first gate drive mechanism; wherein, the compression chamber located at the front is the first compression chamber, and the compression chamber located at the rear is the second compression chamber; the rear side of the second compression chamber has an opening, and a second gate is provided on the rear side of the second compression chamber, through which... A drive mechanism drives the opening and closing; a pusher plate, the front side of the first compression chamber is open, the pusher plate is installed in the compression box in a way that allows it to move back and forth, and the pusher plate is driven to move back and forth by a first moving mechanism; a compression bracket, which is installed on the top surface of the compression box in a way that allows it to move back and forth, and the compression bracket is driven to move back and forth by a second moving mechanism; and a compression head, which is installed on the compression bracket, and the compression head is used to compress the waste in the first compression chamber or the waste in the second compression chamber.

[0005] Preferably, in the above technical solution, the first gate can move up and down, and the first gate driving mechanism includes two first hydraulic cylinders. The two first hydraulic cylinders are respectively installed on the left and right outer side walls of the compression box, and the upper end of each first hydraulic cylinder is connected to the upper end of the first gate.

[0006] Preferably, in the above technical solution, the second gate can move up and down, and the second gate driving mechanism includes two second hydraulic cylinders. The two second hydraulic cylinders are installed on the left and right outer walls of the compression box, and the upper end of each second hydraulic cylinder is connected to the upper end of the second gate.

[0007] Preferably, in the above technical solution, the first moving mechanism includes a pushing hydraulic cylinder, which is installed inside the compression box, and the rear end of the pushing hydraulic cylinder is connected to the front side of the pushing plate.

[0008] Preferably, in the above technical solution, the second moving mechanism includes: at least two guide rails, both of which are installed on the top surface of the compression box and are distributed parallel to each other; rollers, the compression bracket is provided with at least two rollers that cooperate with each guide rail at positions corresponding to each guide rail; and a driving device, which is installed on the compression bracket and is used to drive the rollers to move back and forth along the guide rails.

[0009] Preferably, in the above technical solution, each of the compression chambers is provided with a material sensor at the top to obtain the height of the waste in the compression chamber.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The garbage compressor of this utility model has two compression chambers inside the compression box. By moving the compression support, the compression head can select one compression chamber for compression while the other compression chamber continues to feed. After the garbage compression is completed, the compression head can move to the other compression chamber for further compression, while the first compression chamber can continue to feed, waiting for subsequent compression, until the garbage in both compression chambers is completed. After the compressed garbage block reaches the specified height, the first and second gates are opened to push the two garbage blocks out from the rear. The structure is simple. During the garbage compression process, feeding can continue without waiting time, which can improve the efficiency of garbage collection, compression and transportation.

[0012] 2. The garbage compressor of this utility model can set the height of the garbage block after compression as needed, thereby accurately controlling the volume and weight of each garbage block; for example, after compressing one garbage block in each compression chamber, more than 15% of the volume can be left as a reserve. After compressing all two garbage blocks, in the dual compression chamber mode, the compressor can reserve more than 30% of the total volume to prevent the garbage from accumulating and overflowing the compression chamber after the user continues to pour in a small amount of garbage.

Detailed Implementation

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0023] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0024] Figures 1 to 7 The diagram shows a structural schematic of a dual-compression chamber sliding garbage compressor according to a preferred embodiment of the present invention. The garbage compressor includes a compression chamber 1, a pusher plate 7, a compression bracket 4, and a compression head 3.

[0025] refer to Figures 1 to 7The compression chamber 1 has two compression chambers distributed along the front-to-back direction. Each compression chamber has an opening at the top to facilitate the compression of waste by the subsequent compression head 3. The two compression chambers are separated by a first gate 11, which is opened and closed by a first gate drive mechanism. This gate opens and closes the connecting channel between the two compression chambers, facilitating waste compression and the pushing of the compressed waste blocks. The compression chamber located at the front is the first compression chamber 8, and the compression chamber located at the rear is the second compression chamber 9. The rear side of the second compression chamber 9 has an opening, and a second gate 6 is located at the rear side of the second compression chamber 9. The second gate 6 is opened and closed by a second gate drive mechanism to facilitate the discharge of the waste blocks. The front of the first compression chamber 8 is open, and a pusher plate 7 is provided on the front of the first compression chamber 8. The pusher plate 7 is installed in the compression box 1 in a way that allows it to move back and forth, and is driven to move back and forth by a first moving mechanism to push the garbage blocks in the two compression chambers to the rear, facilitating the discharge operation. The compression bracket 4 is installed on the top surface of the compression box 1 in a way that allows it to move back and forth, and is driven to move back and forth by a second moving mechanism. The compression head 3 is installed on the compression bracket 4. The compression head 3 is used to compress the garbage in the first compression chamber 8 or the garbage in the second compression chamber 9. By moving the compression bracket 4, the compression head 3 can be moved above either compression chamber as needed to perform garbage compression; or, the compression head 3 can be moved above the pusher plate 7 to fully open the top openings of the two compression chambers, facilitating the feeding operation. The garbage compressor of this invention has two compression chambers in the compression box 1. By moving the compression bracket 4, the compression head 3 can select one compression chamber for compression while the other compression chamber continues to feed. After the garbage is compressed, the compression head 3 can move to the other compression chamber for further compression, while the first compression chamber continues to feed, waiting for subsequent compression, until the garbage in both compression chambers is compressed. After the compressed garbage block reaches the specified height, the first gate 11 and the second gate 6 are opened to push the two garbage blocks out from the rear. The structure is simple. During the garbage compression process, feeding can continue without waiting time, which can improve the efficiency of garbage collection, compression and transportation. At the same time, the height of the garbage block after compression can be set as needed, so as to accurately control the volume and weight of each garbage block. For example, after compressing one garbage block in each compression chamber, more than 15% of the volume can be left as a reserve. After compressing both garbage blocks, in the dual compression chamber mode, the compressor can reserve more than 30% of the total volume to prevent garbage from accumulating and overflowing the compression chamber after the user continues to pour in a small amount of garbage.

[0026] refer to Figures 1 to 4 , Figure 7The first gate 11 can be opened and closed by moving up and down or by moving left and right. Preferably, the first gate 11 can move up and down. The first gate driving mechanism includes two first hydraulic cylinders 5, which are respectively installed on the left and right outer walls of the compression chamber 1. The upper end of each first hydraulic cylinder 5 is connected to the upper end of the first gate 11. By extending and retracting the two first hydraulic cylinders 5, the opening and closing of the first gate 11 can be driven, thereby facilitating the discharge of waste blocks from the first compression chamber 8.

[0027] refer to Figures 1 to 4 , Figure 7 The second gate 6 can be opened and closed by moving up and down, moving left and right, or rotating up and down. Preferably, the second gate 6 can move up and down, and the second gate driving mechanism includes two second hydraulic cylinders (not shown in the figure). The two second hydraulic cylinders are installed on the outer walls of the left and right sides of the compression chamber 1, and the upper end of each second hydraulic cylinder is connected to the upper end of the second gate 6. By extending and retracting the second hydraulic cylinders, the second gate 6 can be driven to open and close, thereby facilitating the discharge of waste blocks from the two compression chambers.

[0028] refer to Figures 5 to 7 Preferably, the first moving mechanism includes a pushing hydraulic cylinder 14, which is installed inside the compression chamber 1. The length of the pushing hydraulic cylinder 14 is distributed along the front-to-back direction, and the rear end of the pushing hydraulic cylinder 14 is connected to the front side of the pushing plate 7, while the front end of the pushing hydraulic cylinder 14 is connected to the compression chamber. By extending and retracting the pushing hydraulic cylinder 14, the pushing plate 7 can be driven to move back and forth. When moving backward, it can push the garbage blocks in the two compression chambers outward to the rear opening, completing the discharge operation. After the discharge operation is completed, the pushing hydraulic cylinder 14 retracts, and the pushing plate 7 returns to its original position.

[0029] refer to Figures 1 to 4Preferably, the second moving mechanism includes at least two guide rails 2, rollers, and a driving device. Both guide rails 2 are mounted on the top surface of the compression box 1 and are distributed parallel to each other horizontally. The compression bracket 4 has at least two rollers at positions corresponding to each guide rail 2, which cooperate with the guide rail 2 to allow the compression bracket 4 to move back and forth along the guide rail 2. The driving device is mounted on the compression bracket 4 and is used to drive the rollers to move back and forth along the guide rail 2. The structure is simple and the movement is convenient. The driving device is a hydraulic cylinder structure; the front end of the hydraulic cylinder is connected to the compression box 1 via a bracket, and the rear end of the hydraulic cylinder is connected to the compression bracket 4. The extension and retraction of the hydraulic cylinder drives the compression bracket 4 to move back and forth along the guide rail 2. Alternatively, the driving device is a motor or hydraulic motor mounted on the compression bracket 4, used to drive the rollers to rotate forward or backward, thereby driving the compression bracket 4 to move back and forth along the guide rail 2. To prevent the movement of the first gate 11 from interfering with the movement of the compression bracket 4, the two guide rails 2 can be located on the left and right sides of the first gate 11, that is, the first gate 11 and the two first hydraulic cylinders 5 are located between the two guide rails 2. When the first gate 11 is closed, the height of the first gate 11 and the height of each first hydraulic cylinder 5 do not exceed the height of the first guide rail 2, so as to facilitate the movement of the compression bracket 4; or, the two first hydraulic cylinders 5 are located on the outside of the two guide rails 2, and each first hydraulic cylinder 5 is connected to the top of the first gate 11 through a connecting plate 12. Each guide rail 2 has a channel 13 at the position corresponding to the connecting plate 12 for the connecting plate 12 to move up and down, so as to avoid interfering with the up and down movement of the first gate 11; when the first gate 11 is closed, the height of the first gate 11, the height of each first hydraulic cylinder 5 and the height of each connecting plate 12 do not exceed the height of the first guide rail 2, so as to facilitate the movement of the compression bracket 4.

[0030] refer to Figure 1 Preferably, each compression chamber is equipped with a material sensor 10 at its top to obtain the height of the waste inside the compression chamber, thereby controlling the feeding operation. When the waste height reaches a specified height, feeding stops, and the compression head 3 is moved to the top of the corresponding compression chamber to perform waste compression. The material sensor 10 is either a distance sensor or a photoelectric sensor.

[0031] refer to Figures 1 to 7During use, both the first gate 11 and the second gate 6 are closed. The compression bracket 4 is moved above the pusher plate 7, making the tops of both compression chambers open for easy feeding. At this time, material can be fed from the rear end or from either the left or right ends of the compression chamber, offering diverse feeding methods. Material from the rear end can be poured into one compression chamber alone or at the center line of both chambers. If too much waste is poured into one compression chamber, it can be manually moved to the other chamber. Compared to the existing method of moving excess waste to the transfer station, this avoids contaminating the transfer station and improves work efficiency. When the material sensor 10 detects that the waste height in the compression chamber has reached the specified height, the compression bracket 4 moves along the guide rail 2 above that chamber, controlling the compression head 3 to perform compression. At this time, the other compression chamber can continue to feed. Subsequently, the compression head 3 moves above the other compression chamber for compression, and the first compression chamber can then resume feeding. This cycle repeats, allowing for faster compression of two waste blocks, thus improving the efficiency of waste collection, compression, and transfer. After the garbage compression in both compression chambers is completed, the compression bracket 4 moves forward to the initial position, opens the first gate 11 and the second gate 6, extends the pushing hydraulic cylinder 14, drives the pushing plate 7 to move backward, pushes the two garbage blocks backward, and completes the discharge operation.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
