Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically a horizontal waste compressor. Background Technology

[0002] Horizontal garbage compactors are high-efficiency solid waste treatment equipment used in garbage transfer stations. They employ horizontal compression technology to significantly reduce garbage volume and improve transportation efficiency. They are suitable for scenarios involving municipal solid waste and industrial waste. Normally, the compactor box is located below ground level. After garbage is dumped in, the hydraulic system horizontally compresses it to reduce its volume. After compression, the lifting system pushes the compactor box above ground, thus pushing the garbage out for transfer. The structure is simple and the operating cost is low. However, it is generally impossible to detect the height of the compactor box. Users often need to adjust the height visually and dock it with the garbage truck. There is also a lack of detection of the overlap between the compactor box and the truck bed, making the operation process relatively cumbersome. The end of the compactor box often has a gap with the garbage truck bed, failing to form a connection. As a result, the compactor box itself has poor stability when the garbage is pushed out and is easily damaged, leading to poor performance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a horizontal garbage compressor that can detect the height of its own compression box and the overlap status between the compression box and the garbage transfer vehicle. This facilitates the control of the lifting system and allows for dynamic overlap, improving the stability when garbage is pushed out and providing good performance. This effectively solves the problems in the background technology.

[0007] Furthermore, the right ends of both the front and rear sides of the compression box are provided with protective shells. The proximity switch, baffle, slide, slide column and spring are all located inside the vertically corresponding protective shells. The lower ends of the two protective shells are slidably connected to the upper end of the U-shaped frame to protect the internal components.

The piston chamber of hydraulic cylinder two is connected to the second output port of the hydraulic station through the second oil inlet pipe, and the piston rod chamber of hydraulic cylinder two is connected to the second return oil port of the hydraulic station through the second return oil pipe, which facilitates the compression of waste.

[0010] Furthermore, the lifting assembly includes two cross scissor arms. The lower right ends of both cross scissor arms are rotatably connected to the base plate, and the lower left ends of both cross scissor arms are slidably connected to the base plate. The upper right ends of both cross scissor arms are rotatably connected to the compression box, and the upper left ends of both cross scissor arms are slidably connected to the compression box.

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.

The base plate 1 is fixed to the inside of a pit in the ground, and the upper surface of the compression box 3 is flush with the ground. The cover door at the top of the compression box 3 is opened, and garbage is poured into the inside of the compression box 3. Then the cover door is closed and locked with a pin. A distance sensor 18 is provided at the left end inside the compression box 3, and a circular hole corresponding to the distance sensor 18 is opened on the bottom wall of the compression box 3. The compression box 3 moves the distance sensor 18 upwards simultaneously. A vertically movable U-shaped frame 6 is slidably connected below the discharge port at the right end of the compression box 3, and a corresponding U-shaped frame 6 is opened on the lower surface of the compression box 3. The compression box 3 has two proximity switches 7 on its left and right sides, each of which is configured to cooperate with the U-shaped frame 6. The U-shaped frame 6 has sliding pillars 8 at both its front and rear ends, and sliding blocks 9 on the right ends of both its front and rear sides. The sliding pillars 8 are slidably connected to the vertically corresponding sliding blocks 9. Each sliding pillar 8 has a baffle 10 at its upper end, located above the sliding blocks 9. Springs 11 are movably sleeved on the outside of each sliding pillar 8, located between the U-shaped frame 6 and the sliding blocks 9. The springs 11 facilitate the downward movement of the U-shaped frame 6. The proximity switches 7 are located above the baffles 10. When the compression box 3 moves the U-shaped frame 6 downwards, and the U-shaped frame 6 contacts the carriage, it stops moving downwards and will move relative to the continuing downward-moving compression box 3, thereby causing the sliding pillars 8 and... The slide block 9 is in a relative sliding connection. Protective shells 12 are provided on the right ends of both the front and rear sides of the compression box 3. Proximity switch 7, baffle 10, slide block 9, slide column 8, and spring 11 are all located inside the vertically corresponding protective shells 12. The lower ends of both protective shells 12 are slidably connected to the upper ends of the U-shaped frame 6. The protective shells 12 provide protection for the internal components. A hydraulic station 15 is provided at the lower end of the control box 4. The input end of the hydraulic station 15 is electrically connected to the output end of the PLC controller 5. A baffle 13 is movably inserted into the right end of the compression box 3. Hydraulic cylinder 14 is provided on the right ends of both the front and rear sides of the compression box 3. The extension and retraction ends of hydraulic cylinder 14 are fixedly connected to the upper ends of the baffle 13. A hydraulic cylinder 2 16 is provided at the left end of the compression box 3. A sliding connection is provided in the middle of the compression box 3. The pressure plate 17 and the telescopic end of hydraulic cylinder 16 are fixedly connected to the left side of the pressure plate 17. Hydraulic cylinder 202 is a multi-stage hydraulic cylinder with a multi-stage sleeve-shaped piston rod having a long telescopic length. The piston chamber of hydraulic cylinder 14 is connected to the first output port of hydraulic station 15 through the first oil inlet pipe, and the piston rod chamber of hydraulic cylinder 14 is connected to the first return port of hydraulic station 15 through the first return oil pipe. The piston chamber of hydraulic cylinder 16 is connected to the second output port of hydraulic station 15 through the second oil inlet pipe, and the piston rod chamber of hydraulic cylinder 16 is connected to the second return port of hydraulic station 15 through the second return oil pipe. When hydraulic station 15 operates, it controls hydraulic cylinder 16 to extend. The telescopic end of hydraulic cylinder 16 drives the pressure plate 17 to slide to the right along the inner wall of the compression box 3.Baffle 13 blocks the waste inside the compression box 3, and pressure plate 17 squeezes the waste. Then, hydraulic station 15 controls the extension end of hydraulic cylinder 16 to retract, driving pressure plate 17 to reset. The waste can then be repeatedly compressed until it is full. The extension end of hydraulic cylinder 14 drives baffle 13 to pull upward, opening the right end of compression box 3. Lifting assembly 2 includes cross scissor arms 201 and hydraulic cylinder 202. There are two cross scissor arms 201. The lower right end of both cross scissor arms 201 is rotatably connected to the base plate 1, the lower left end of both cross scissor arms 201 is slidably connected to the base plate 1, the upper right end of both cross scissor arms 201 is rotatably connected to the compression box 3, and the upper left end of both cross scissor arms 201 is slidably connected to the compression box 3. The two hydraulic cylinders 202 are rotatably connected to the middle of the base plate 1, and the extension ends of both hydraulic cylinders 202 are rotatably connected to the longitudinally adjacent cross scissor arms 201. The piston chamber of hydraulic cylinder 3 202 is connected to the third output port of hydraulic station 15 via the third inlet oil pipe. The piston rod chamber of hydraulic cylinder 3 202 is connected to the third return oil port of hydraulic station 15 via the third return oil pipe. Hydraulic station 15 controls the extension of the telescopic end of hydraulic cylinder 3 202. The cross scissor arm 201 consists of two sets of cross linkages, forming a diamond-shaped linkage structure through the central hinge point. When hydraulic cylinder 3 202 pushes the cross scissor arm 201, the cross scissor arm 201 deforms to lift the compression box 3. The left end of the upper surface of the base plate 1 is equipped with a proximity switch 20 via a bracket. The left end of the front side of the compression box 3 is equipped with a metal block 19, which is made of stainless steel. The metal block 19 is configured to cooperate with proximity switch 20. The output end of proximity switch 20 is electrically connected to the input end of PLC controller 5. After the compression box 3 moves down and resets, the metal block 19 corresponds to proximity switch 20, and proximity switch 20 generates an electrical signal.

[0021] The system also includes a control box 4, located behind the compression box 3. The control box 4 provides protection for the internal components. A PLC controller 5 is located at the upper part of the control box 4. The output terminals of the distance sensor 18 and proximity switch 7 are electrically connected to the input terminal of the PLC controller 5. The compression box 3 moves the distance sensor 18 upwards simultaneously. The distance sensor 18 detects the upward height of the compression box 3 and transmits the detection result to the PLC controller 5. The PLC controller 5 controls the hydraulic station 15 according to the height set by the user. The baffle 10 approaches the proximity switch 7, and the proximity switch 7 sends an electrical signal to the PLC controller 5. The PLC controller 5 controls the solenoid valve on the hydraulic station 15. The proximity switch 20 sends an electrical signal to the PLC controller 5 to confirm the reset of the compression box 3 and to verify the distance sensor 18.

[0022] The working principle of the horizontal garbage compactor provided by this utility model is as follows: Before use, the base plate 1 is fixed to the pit in the ground, and the upper surface of the compression box 3 is flush with the ground. When using, open the cover door at the top of the compression box 3, then pour the garbage into the inside of the compression box 3, then close the cover door and lock it with the latch. Then, control the PLC controller 5, and the hydraulic station 15 works. The hydraulic station 15 controls the extension of the second hydraulic cylinder 16. The extension end of the second hydraulic cylinder 16 drives the pressure plate 17 to slide to the right along the inner wall of the compression box 3. The baffle 13 blocks the garbage inside the compression box 3, and the pressure plate 17 squeezes the garbage. Then, the hydraulic station 15 controls the extension end of the second hydraulic cylinder 16 to retract, driving... The pressure plate 17 resets, and then the garbage can be repeatedly compressed until it is full. When the garbage is transferred, the hydraulic station 15 controls the extension end of the hydraulic cylinder 202 to extend. The cross scissor arm 201 is composed of two sets of cross linkages, forming a diamond linkage structure through the central hinge point. When the hydraulic cylinder 202 pushes the cross scissor arm 201, the cross scissor arm 201 deforms and lifts the compression box 3. The compression box 3 drives the distance sensor 18 to move upward at the same time. The distance sensor 18 detects the upward height of the compression box 3 and transmits the detection result to the PLC controller 5. The PLC controller 5 controls the hydraulic station 15 according to the height set by the user. The hydraulic station 15 controls the hydraulic... When cylinder 3 (202) stops extending, compression box 3 stops moving upwards, allowing it to be lifted to different heights above the ground for easier docking with different garbage trucks. During docking, the garbage truck reverses to the left, inserting the right end of compression box 3 slightly. The U-shaped frame 6 is inside the truck bed, while the baffle 13 is not. Then, the telescopic end of hydraulic cylinder 14 pulls the baffle 13 upwards, opening the right end of compression box 3. Next, the telescopic end of hydraulic cylinder 3 (202) retracts, causing compression box 3 to move the U-shaped frame 6 downwards. After the U-shaped frame 6 contacts the truck bed, it stops moving downwards and relative to the continuing downward-moving compression box 3, resulting in a relative sliding connection between the sliding column 8 and the sliding seat 9. When the baffle 10 approaches the proximity switch 7, the proximity switch 7 sends an electrical signal to the PLC controller 5. The PLC controller 5 controls the solenoid valve on the hydraulic station 15, and the hydraulic cylinder 202 stops retracting. The compression box 3 will connect with the truck body. Then, the extension end of the hydraulic cylinder 16 drives the pressure plate 17 to push the garbage to the right into the truck body. After the truck body moves down under gravity, the U-shaped frame 6 moves down synchronously under the action of the spring 11. The baffle 10 moves away from the proximity switch 7. The proximity switch 7 sends an electrical signal to the PLC controller 5, thereby controlling the compression box 3 to move down synchronously, which can maintain dynamic connection. After being pushed in, the baffle 13 closes, the compression box 3 is lifted and the vehicle is moved away, and the compression box 3 moves down to reset.

[0023] It is worth noting that the PLC controller 5, proximity switch 7, ranging sensor 18, hydraulic station 15, and proximity switch 20 disclosed in the above embodiments can all be freely configured according to the actual application scenario. The PLC controller 5 can be a PLC controller of model S7-1500T, and both proximity switches 7 and 20 can be proximity switches of model E2E-X10ME1-Z. The PLC controller 5 controls the operation of proximity switch 7, ranging sensor 18, hydraulic station 15, and proximity switch 20 using methods commonly used in the prior art. The hydraulic station 15 controls the operation of hydraulic cylinder 14, hydraulic cylinder 26, and hydraulic cylinder 3202 using methods commonly used in the prior art.
