Bidirectional telescopic garbage compression equipment for garbage transfer station

Abstract

The utility model discloses bidirectional telescopic garbage compression equipment for a garbage transfer station, and relates to the technical field of garbage compression equipment. The box comprises a box body. If the top end does not reach the scale mark after garbage is poured, a worker operates the controller at the moment, the controller controls the second compression mechanism to move towards the garbage in the compression bin, and when the second compression mechanism just enters the compression bin, the worker operates the controller again at the moment, so that the second compression mechanism is compressed. The controller controls the first compression mechanism to work, then the first compression mechanism gets close to the direction of the garbage, namely the first compression mechanism and the second compression mechanism get close to each other to move, and the garbage is extruded and compressed on the two sides through the first compression mechanism and the second compression mechanism; therefore, the situation that the other side of the garbage is loose and fluffy due to the fact that one side of the garbage is stressed in the compression bin is prevented, the garbage compression density is greatly improved, the occupied transportation space is reduced, and the transportation cost is reduced.

Description

Technical Field

[0001] This utility model belongs to the technical field of waste compression equipment, and specifically relates to a bidirectional telescopic waste compression device for waste transfer stations. Background Technology

[0002] With the acceleration of urbanization, the amount of urban waste generated is increasing daily, making waste transfer stations increasingly crucial in urban waste management systems. As a vital link connecting front-end waste collection and end-stage waste treatment, the performance of waste transfer station equipment directly affects the efficiency and quality of waste disposal.

[0003] Due to the unidirectional compression characteristic, during the compression process, the side of the garbage subjected to force is compacted and tightly packed due to direct compression, while the other side remains loose and fluffy. This makes it difficult to achieve sufficient compression of the garbage, resulting in a low density of the compressed garbage, which occupies a large amount of transportation space and significantly increases the frequency and cost of transportation. At the same time, based on the principle of force interaction, the garbage on the compressed side is prone to sticking to the surface of the compression device when subjected to strong compression, making it dirty and messy.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a bidirectional telescopic garbage compression device for garbage transfer stations to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a bidirectional telescopic garbage compression device for a garbage transfer station, comprising a housing, an ejection mechanism inside the housing, a connecting shell fixedly installed at the bottom of the housing, a first compression mechanism inside the connecting shell, a lifting gate mechanism inside the housing, and a compression chamber formed by the ejection mechanism, the first compression mechanism, and the lifting gate mechanism. A support frame is fixedly installed outside the housing, a second compression mechanism is installed at one end of the support frame, the first compression mechanism is located directly below the second compression mechanism, a discharge port sealing mechanism is installed at the top of the housing, a controller is installed at one end of the support frame, and graduation lines are provided on the housing and inside the compression chamber.

[0008] Furthermore, the ejection mechanism includes a pusher head, which is slidably mounted in the inner cavity of the housing. Two first hydraulic cylinders are symmetrically mounted on one end of the pusher head, and the two first hydraulic cylinders are mounted on the housing.

[0009] Furthermore, the first compression mechanism includes a first pressure head, with guide rods fixedly installed at the four corners of the bottom of the first pressure head, and the four guide rods are slidably installed on the connecting shell. Two second hydraulic cylinders are symmetrically fixedly installed at the bottom of the first pressure head, and the two second hydraulic cylinders are installed on the connecting shell.

[0010] Furthermore, the lifting center door mechanism includes a lifting center door, which is slidably mounted on the housing. A third hydraulic cylinder is fixedly mounted at both ends of the lifting center door, and two of the third hydraulic cylinders are mounted on both sides of the housing.

[0011] Furthermore, the second compression mechanism includes a second pressure head, on the top of which a fourth hydraulic cylinder is symmetrically mounted, and two of the fourth hydraulic cylinders are mounted on the support frame.

[0012] Furthermore, the unloading port sealing mechanism includes a fifth hydraulic cylinder, which is mounted on the housing. A sealing plate is installed on the telescopic end of the fifth hydraulic cylinder, and the sealing plate is slidably mounted on the housing.

[0013] Furthermore, a cleaning blade is mounted on the end of the sealing plate away from the fifth hydraulic cylinder, with the cutting edge of the cleaning blade located at its top.

[0014] This utility model has the following beneficial effects:

[0015] If the top of the garbage after being poured in does not reach the scale line, the operator will then operate the controller to move the second compression mechanism towards the garbage in the compression chamber. Once the second compression mechanism has just entered the chamber, the operator will operate the controller again to control the first compression mechanism. The first compression mechanism will then move closer to the garbage. This mutual compression of the garbage by both mechanisms prevents it from becoming loose and fluffy due to unilateral force within the compression chamber, significantly increasing the garbage compression density, reducing transportation space requirements, and lowering transportation costs.

[0016] After the garbage is compressed, the operator uses a controller to restore the first and second compression mechanisms to their initial positions. When the second compression mechanism rises to the top of the discharge port sealing mechanism, it stops working. At this time, the controller moves the discharge port sealing mechanism towards the compression chamber, gradually sealing it. As the discharge port sealing mechanism moves, it also moves along the bottom of the second compression mechanism where the garbage is compressed. As the discharge port sealing mechanism moves, its edge structure scrapes off the garbage attached to the second compression mechanism. When the discharge port sealing mechanism covers the top of the compression chamber, all the garbage on it will be scraped off, thus reducing the amount of manual cleaning work.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] This embodiment provides a bidirectional telescopic waste compression device for a waste transfer station. Please refer to [link / reference]. Figures 1-7 As shown, the device includes a housing 1, an ejection mechanism 2 inside the housing 1, a connecting shell 3 fixedly installed at the bottom of the housing 1, a first compression mechanism 4 inside the connecting shell 3, a lifting middle door mechanism 5 inside the housing 1, and a compression chamber 6 formed by the ejection mechanism 2, the first compression mechanism 4, and the lifting middle door mechanism 5. A support frame 7 is fixedly installed outside the housing 1, a second compression mechanism 8 is installed at one end of the support frame 7, the first compression mechanism 4 is located directly below the second compression mechanism 8, a discharge port sealing mechanism 9 is installed at the top of the housing 1, a controller 10 is installed at one end of the support frame 7, and a scale line 11 is provided on the housing 1 and inside the compression chamber 6.

[0031] The controller 10 is electrically connected to the ejection mechanism 2, the first compression mechanism 4, the lifting gate mechanism 5, the second compression mechanism 8, and the unloading port sealing mechanism 9. The controller 10 serves as the core control hub of the equipment and has a built-in programmable logic controller (PLC) system to control the operation of the ejection mechanism 2, the first compression mechanism 4, the lifting gate mechanism 5, the second compression mechanism 8, and the unloading port sealing mechanism 9. This is existing technology and is not considered an innovation in this solution, but rather a means to better understand this solution.

[0032] The container 1 and connecting shell 3 are buried underground, while the support frame 7 is installed on the ground at the garbage transfer station. After the garbage truck pours the collected garbage into the compression chamber 6, the staff observes the distance between the top of the poured garbage and the scale line 11. The scale line 11 is set at three-quarters of the height of the compression chamber 6 from bottom to top, depending on the requirements. If the top of the poured garbage does not reach the scale line 11, the staff operates the controller 10. The controller 10 controls the second compression mechanism 8 to move towards the garbage in the compression chamber 6, etc. When the second compression mechanism 8 enters the compression chamber 6, the staff will operate the controller 10 to control the first compression mechanism 4 to work. Then the first compression mechanism 4 will move closer to the garbage, that is, the first compression mechanism 4 and the second compression mechanism 8 move closer to each other. The first compression mechanism 4 and the second compression mechanism 8 squeeze and compress the garbage on both sides, thereby preventing the garbage from being loose and fluffy on the other side due to force on one side in the compression chamber 6. This greatly increases the garbage compression density, reduces the space occupied in transportation, and reduces transportation costs.

[0033] After the garbage is compressed, the staff operates the controller 10 to control the first compression mechanism 4 and the second compression mechanism 8 to return to their initial positions. When the second compression mechanism 8 rises to the top of the discharge port sealing mechanism 9, the second compression mechanism 8 stops working. At this time, the controller 10 controls the discharge port sealing mechanism 9 to move closer to the compression chamber 6 and gradually seal the compression chamber 6. During the movement of the discharge port sealing mechanism 9, the discharge port sealing mechanism 9 will also move along the part of the second compression mechanism 8 that is compressing garbage. As the discharge port sealing mechanism 9 moves, the edge structure of the discharge port sealing mechanism 9 can scrape off the garbage attached to the second compression mechanism 8. When the discharge port sealing mechanism 9 covers the top of the compression chamber 6, all the garbage on the discharge port sealing mechanism 9 will also be scraped off, thereby reducing the amount of manual cleaning work. When the collection vehicle needs to dump garbage into the compression chamber 6, the staff will operate the controller 10 again to control the discharge port sealing mechanism 9 to work, so that the compression chamber 6 opens and the garbage is dumped into it.

[0034] If the garbage dumped by the collection truck is at or above the 11 mark, the staff will operate the controller 10 to control the second compression mechanism 8 to compress the garbage. The garbage dumping and compression process will be repeated until the compression chamber 6 is full. Then, the staff will operate the controller 10 to control the lifting door mechanism 5 to rise. The storage chamber is located inside the container 1, so the storage chamber inside the container 1 will be opened. Then, the staff will operate the controller 10 to control the push mechanism 2 to start. The push mechanism 2 will push the compressed garbage into the storage chamber. Then, the staff will control the lifting door mechanism 5 and the push mechanism 2 to return to their initial positions, waiting for subsequent transfer.

[0035] In another embodiment, the ejection mechanism 2 includes a push head 201, which is slidably mounted in the inner cavity of the housing 1. Two first hydraulic cylinders 202 are symmetrically mounted on one end of the push head 201, and the two first hydraulic cylinders 202 are mounted on the housing 1.

[0036] The lifting middle door mechanism 5 includes a lifting middle door 501, which is slidably mounted on the housing 1. A third hydraulic cylinder 502 is fixedly mounted at both ends of the lifting middle door 501, and the two third hydraulic cylinders 502 are mounted on both sides of the housing 1.

[0037] When the waste in the compression chamber 6 is compressed to full capacity, the controller 10 sends a command to the lifting gate mechanism 5 to activate the third hydraulic cylinders 502 installed on both sides of the container 1. The hydraulic oil in the third hydraulic cylinders 502 is pressurized, pushing its piston rod upward. Since the two ends of the lifting gate 501 are fixedly connected to the piston rods of the third hydraulic cylinders 502, under the synchronous upward force of the third hydraulic cylinders 502 on both sides, the lifting gate 501 moves upward along the guide rail of the container 1, gradually opening the storage chamber entrance. When the lifting gate 501 rises to the preset height, the controller... The controller 10 stops the third hydraulic cylinder 502 from working, and sends a working command to the push-out mechanism 2 to start the two first hydraulic cylinders 202 installed on the box 1. The hydraulic oil in the first hydraulic cylinder 202 generates high pressure thrust under the action of the hydraulic pump, pushing the piston rod to extend. Since the push head 201 is connected to one end of the piston rod of the first hydraulic cylinder 202, under the synchronous force of the two first hydraulic cylinders 202, the push head 201 slides smoothly along the slide rail inside the box 1, and pushes the compressed garbage into the storage compartment inside the box 1 with a constant thrust.

[0038] In another embodiment, the first compression mechanism 4 includes a first pressure head 401, with guide rods 402 fixedly installed at the four corners of the bottom of the first pressure head 401. The four guide rods 402 are slidably installed on the connecting shell 3. Two second hydraulic cylinders 403 are symmetrically fixedly installed at the bottom of the first pressure head 401, and the two second hydraulic cylinders 403 are installed on the connecting shell 3.

[0039] The second compression mechanism 8 includes a second pressure head 801, and a fourth hydraulic cylinder 802 is symmetrically mounted on the top of the second pressure head 801. The two fourth hydraulic cylinders 802 are mounted on the support frame 7.

[0040] The unloading port sealing mechanism 9 includes a fifth hydraulic cylinder 901, which is mounted on the housing 1. A sealing plate 902 is installed on the telescopic end of the fifth hydraulic cylinder 901, and the sealing plate 902 is slidably mounted on the housing 1.

[0041] A cleaning blade 903 is installed on the end of the sealing plate 902 away from the fifth hydraulic cylinder 901, and the blade of the cleaning blade 903 is located at its top.

[0042] After the garbage truck dumps the garbage into the compression chamber 6, and the staff observes the distance between the top of the dumped garbage and the scale line 11, if the top of the dumped garbage does not reach the scale line 11, the staff operates the controller 10 to send a start command to the first compression mechanism 4. At this time, the two second hydraulic cylinders 403 installed on the housing 1 start working. The hydraulic pump pressurizes hydraulic oil into the second hydraulic cylinders 403, pushing the piston rods upward. Since the piston rods of the second hydraulic cylinders 403 are symmetrically fixed at the bottom of the first pressure head 401, under the synchronous force of the two second hydraulic cylinders 403, the first pressure head 401 will move along the connecting shell 3 with four guide rods 402. The guide rods 402 play a guiding role to ensure that the first pressure head 401 moves vertically and avoids deviation during compression. 01 moves upward continuously, applying pressure to the waste in the compression chamber 6. At the same time, the controller 10 also issues a command to the second compression mechanism 8, and the two fourth hydraulic cylinders 802 installed on the support frame 7 are activated. Hydraulic oil enters the fourth hydraulic cylinders 802 under the action of the hydraulic pump, pushing the piston rod to extend downward. Since the piston rods of the fourth hydraulic cylinders 802 are symmetrically installed on the top of the second pressure head 801, the four fourth hydraulic cylinders 802 on both sides synchronously push the second pressure head 801 to move downward, squeezing the waste in the compression chamber 6. During the compression process, the second pressure head 801 and the first pressure head 401 apply pressure to the waste from both the top and bottom directions, so that the waste is subjected to uniform force, effectively avoiding the problem of loose waste caused by unilateral compression. Then, the controller 10 is operated to control the first compression mechanism 4 and the second compression mechanism 8 to return to the initial position.

[0043] If the garbage dumped by the collection vehicle is at or above the 11 mark, the operator can operate the second compression mechanism 8 alone to compress the garbage. This operation is repeated until the compression chamber 6 is full. Each time the second compression mechanism 8 finishes compressing the garbage, when the second pressure head 801 of the second compression mechanism 8 rises to the same level as the blade of the cleaning knife 903, the controller 10 sends a command to the unloading port sealing mechanism 9 to activate the fifth hydraulic cylinder 901 installed on the box 1. The piston rod of the fifth hydraulic cylinder 901 extends, pushing the sealing plate 902 connected to it to slide along the slide rail on the box 1 towards the compression chamber 6. The sealing plate 902 moves and gradually seals the discharge port of the compression chamber 6. Since the blade of the cleaning blade 903 is located at the top, it can contact the bottom of the second pressure head 801 during the movement of the sealing plate 902, scraping off the garbage attached to the second pressure head 801. When the sealing plate 902 completely covers the top of the compression chamber 6, the discharge port is sealed. At this time, the cleaning blade 903 also cleans all the garbage on the surface of the second pressure head 801. When it is necessary to dump garbage into the compression chamber 6 again, the controller 10 controls the piston rod of the fifth hydraulic cylinder 901 to retract, driving the sealing plate 902 back to its original position, opening the discharge port of the compression chamber 6, and preparing for the next round of garbage compression operation.
