Description

Technical Field

[0001] The present invention relates to the technical field of garbage recycling, and in particular to a garbage compression device for a garbage truck. Background Art

[0002] Garbage collection trucks are motor vehicles designed specifically for collecting, transporting, and processing garbage. They are widely used in urban sanitation, industrial waste disposal, and community waste collection. With the acceleration of urbanization and rising environmental awareness, the demand for garbage collection trucks is increasing, and their types and functions are constantly expanding and optimizing. Garbage collection trucks include compression trucks, swing-arm trucks, sealed trucks, electric three-wheeled trucks, and unmanned trucks. Compression trucks use a hydraulic system to compress garbage into blocks, increasing loading capacity and transportation efficiency while reducing secondary pollution. Swing-arm trucks use a hydraulic lift mechanism to lift the garbage hopper, making them suitable for municipal sanitation and large factories and mines. Sealed trucks feature a fully sealed structure to prevent garbage leakage. Electric three-wheeled trucks are compact and maneuverable, suitable for confined areas such as residential communities and schools. Unmanned trucks utilize sensors and intelligent control systems for automated garbage collection, improving efficiency and reducing labor costs.

[0003] In China, due to the imperfect implementation of the garbage classification system, garbage collection trucks are often roughly divided into two types: one is the garbage collection truck used to recycle kitchen waste generated by the catering industry, and the other is the ordinary compression collection truck used to recycle general garbage.

[0004] When recycling ordinary garbage, since there is less garbage in the recyclable garbage bin, in practice, the general garbage bin and the recyclable garbage bin are often placed together for recycling. This makes it difficult to sort and recycle the subsequent garbage, and also makes the garbage sorting at the source lose its meaning. For this reason, a garbage compression device for a garbage truck is proposed. Summary of the Invention

[0012] Preferably, the lifting device includes a recovery port, which is opened on the top of the compression compartment body and located above the auxiliary plate. A recovery cover is fixedly installed on the recovery port, a rotating shaft is fixedly installed on one side of the recovery cover, and a cover plate is rotatably installed on the rotating shaft.

[0013] Preferably, a second connecting shaft is fixedly installed on one side of the cover plate, a third hydraulic push rod is installed on the side of the recovery cover close to the second connecting shaft, the second connecting shaft is rotatably installed on the recovery cover away from one end of the output shaft, and the output shaft of the second connecting shaft is rotatably installed on the second connecting shaft.

[0014] Preferably, two guide rail frames are fixedly installed on one side of the compression compartment body, a guide rail groove is opened in the guide rail frame, a guide column is slidably installed in the guide rail groove, an inner mounting frame is fixedly installed between the two guide columns, and a clamping plate is fixedly installed on the inner mounting frame.

[0015] Preferably, an outer mounting frame is slidably mounted inside the inner mounting frame, a clamping claw is fixedly mounted on one side of the outer mounting frame, a second connecting rod is fixedly mounted on one side of the outer mounting frame, a first connecting rod is fixedly mounted on one side of the cover plate, and the first connecting rod is rotatably connected to the second connecting rod.

[0016] Preferably, the partitioning and compressing device includes two pairs of main rails, which are respectively installed on the top two and bottom two sides of the compression carriage main body. The length of the main rails on the top two sides of the compression carriage main body is smaller than the main rails on the bottom two sides of the compression carriage main body.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) By clamping the edge of the recyclable trash can between the card plate and the claw, when the third hydraulic push rod pushes the cover to open, the rotation of the cover will drive the outer mounting frame and the inner mounting frame to rise through the first connecting rod and the second connecting rod. The inner mounting frame will move along the guide rail groove through the guide column to lift the trash can and turn it upside down into the recycling port. At this time, the garbage in the bin will be shaken out by the auxiliary compression device and will enter the compression compartment body near the metal recovery device. By energizing the electromagnet, the electromagnet will generate magnetism, which will attract the metal garbage in the falling garbage to the side of the electromagnet, and the non-metallic garbage will fall directly. The magnetism usually generated by the electromagnet can separate the metal garbage and non-metallic garbage in the recyclable garbage, which is convenient for subsequent recycling.

[0021] (2) The partition plate is installed on the push plate by fixing bolts. The partition plate can be used to divide the main body of the compression compartment into two spaces. The side close to the garbage compression and recovery mechanism is used for normal recycling of general garbage, and the other side of the partition plate is used for recycling recyclable garbage. Similar to the existing compression recycling vehicle, the garbage compression and recovery mechanism is used to compress general garbage and send it into the main body of the compression compartment during recycling. When sending it into the main body of the compression compartment, the partition plate will gradually move backward as the amount of garbage increases. When the partition plate moves backward, the recyclable garbage on the other side will also be appropriately compressed.

[0022] (3) Through the cooperation of the protective slide plate and the spring, when the partition plate is driven to the side of the metal recovery device by the retracted push plate, the push plate will press against the protective slide plate and slide into the protective base plate. The protective slide plate compresses the spring when it moves. When the push plate retracts and drives the partition plate to move to the side of the garbage compression and recovery mechanism, the spring pushes the protective slide plate under the elastic action. At this time, the protective slide plate will always press against the push plate, and the protective slide plate will be used to block the first multi-stage telescopic rod to prevent garbage from scratching the first multi-stage telescopic rod.

[0038] Example 1: Reference Figures 1-9 A garbage compression device for a garbage truck includes a compression compartment body 1 and a garbage compression and recovery mechanism 8.

The output end of the second multi-stage telescopic rod 306 is rotatably connected to the first connecting shaft 303. A small vibration motor 304 is fixedly installed at the bottom of the auxiliary plate 302. A hole is opened on the second hydraulic cylinder 305. The first connecting shaft 303 passes through and is rotatably installed in the hole. The first connecting shaft 303 and the hole gap on the second hydraulic cylinder 305 are matched. The lifting device 4 includes a recovery port 400. The recovery port 400 is opened at the top of the compression compartment body 1. The recovery port 400 is located above the auxiliary plate 302. A recovery cover 401 is fixedly installed on the recovery port 400. A rotating shaft 402 is fixedly installed on one side of the recovery cover 401. A cover plate 403 is rotatably mounted on the rotating shaft 402, a second connecting shaft 405 is fixedly mounted on one side of the cover plate 403, a third hydraulic push rod 406 is mounted on the side of the recovery cover 401 close to the second connecting shaft 405, the second connecting shaft 405 is rotatably mounted on the recovery cover 401 away from one end of the output shaft, the output shaft of the second connecting shaft 405 is rotatably mounted on the second connecting shaft 405, two guide rail frames 407 are fixedly mounted on one side of the compression compartment body 1, a guide rail groove 408 is opened in the guide rail frame 407, a guide column 409 is slidably mounted in the guide rail groove 408, an inner mounting frame 410 is fixedly mounted between the two guide columns 409, a clamping plate 411 is fixedly mounted on the inner mounting frame 410, an outer mounting frame 412 is slidably mounted in the inner mounting frame 410, and an outer mounting frame 412 is fixedly mounted on the inner mounting frame 410. A clamping claw 413 is fixedly installed on one side of the mounting frame 412, a second connecting rod 414 is fixedly installed on one side of the outer mounting frame 412, a first connecting rod 404 is fixedly installed on one side of the cover plate 403, the first connecting rod 404 is rotatably connected to the second connecting rod 414, the mounting block 200 is installed between the two main guide rails 500 at the top and bottom, the fixing seat 300 is installed at the bottom of the main guide rail 500 on the top side of the compression carriage body 1, and the compression carriage body 1 needs to be installed on the frame when in use. During installation, the compression carriage body 1 is rotatably connected to the frame on the side close to the garbage compression and recycling mechanism 8, and each hydraulic cylinder is connected to the hydraulic system, the electrical device is connected to the battery for power supply, and the bottom of the compression carriage body 1 is connected to the hydraulic push rod on the frame.So that the hydraulic cylinder on the frame can be used to rotate and lift the compression compartment body 1, thereby dumping all the garbage in the compression compartment body 1. When in use, the garbage compression and recovery mechanism 8 is the same as the compression and recovery structure and working principle of the existing compression type garbage recovery vehicle on the market. During recycling, the electromagnet 202 is energized to clamp the edge of the recyclable garbage bin on the claw 413. When the output shaft of the third hydraulic push rod 406 is extended, the output shaft of the third hydraulic push rod 406 drives the cover plate 403 to rotate based on the rotating shaft 402. When the cover plate 403 rotates, the recovery port 400 is exposed and the garbage is collected through the first connecting rod 413. The connecting rod 404 and the second connecting rod 414 drive the outer mounting frame 412 to rise. The outer mounting frame 412 rises and drives the trash can to rise and abut against the card plate 411. The card plate 411 and the claw 413 cooperate to clamp the edge of the trash can at this time. As the outer mounting frame 412 rises, the inner mounting frame 410 will also rise in the guide rail groove 408 through the guide column 409. Since the cover plate 403 is rotating and the outer mounting frame 412 needs to move upward, the first connecting rod 404 and the second connecting rod 414 are connected in a rotating manner, so that when the first connecting rod 404 rises, the inner mounting frame 410 will rise in the guide rail groove 408 through the guide column 409. The connecting rod 414 rotates to adapt to its movement trajectory. When the trash can is lifted to the top, it will be inverted on the recycling port 400, and the trash in the trash can will fall into the compression compartment body 1. During the falling process, due to the strong magnetism generated by the electromagnet 202 being energized, the metal trash in the falling trash will be attracted to the electromagnet 202, thereby separating the metal trash from the non-metal trash. At the beginning of the collection, since the compression compartment body 1 is relatively empty, the second multi-stage telescopic rod 306 can be extended by the second hydraulic cylinder 305, and the second multi-stage telescopic rod 306 pushes the auxiliary plate 30 2 rotates, bringing one end of the auxiliary plate 302 closer to the electromagnet 202. This allows the garbage to fall closer to the side of the electromagnet 202, making it easier for the electromagnet 202 to attract the metal garbage. By cooperating with the small vibration motor 304, the auxiliary plate 302 vibrates, making it easier to use the auxiliary plate 302 to shake out the garbage. It is worth noting that the first connecting rod 404 is a two-section connecting rod, which is rotatably connected by a rotating shaft. The rotating shaft is located at the arc angle where the two sections of the connecting rod are connected. The connection point can rotate freely to accommodate the misalignment when the cover plate 403 flips upward and drives the outer mounting frame 412 to rise linearly.

[0040] Example 2: Reference Figure 4 and Figure 8In order to realize the function of compressing garbage, the separation and compression device 5 includes two pairs of main rails 500, which are respectively installed on the top two and bottom sides of the compression compartment main body 1. The main rails 500 on the top two sides of the compression compartment main body 1 are shorter than the main rails 500 on the bottom two sides of the compression compartment main body 1. A first hydraulic cylinder 501 is fixedly installed in the main rails 500, and a first multi-stage telescopic rod 502 is provided on the first hydraulic cylinder 501. A hydraulic synchronization valve 503 is fixedly installed on one side of the compression compartment main body 1. The hydraulic synchronization valve 503 is connected to the main rail 500 through a hydraulic oil pipe. The same push plate 504 is fixedly installed between the first multi-stage telescopic rods 502 on the top two sides of the compression compartment main body 1 and between the first multi-stage telescopic rods 502 on the bottom two sides of the compression compartment main body 1. A partition plate 505 is installed on the push plate 504. The partition plate 505 and the push plate 504 are fixedly installed. A fixing bolt 506 is installed on the thread. When in use, the garbage compression and recovery mechanism 8 has the same compression and recovery structure and working principle as the existing compression-type garbage recovery vehicles on the market. When in use, the partition plate 505 is fixed to the push plate 504 through 206, and the first multi-stage telescopic rod 502 is pushed out to the maximum distance through the first hydraulic cylinder 501. At this time, the partition plate 505 should be located on the side close to the garbage compression and recovery mechanism 8. During recycling, the garbage in the ordinary garbage bin is compressed and recovered into the compression carriage body 1 through the garbage compression and recovery mechanism 8. As the garbage on one side of the garbage compression and recovery mechanism 8 is recovered, the partition plate 505 will be pushed toward the side of the metal recovery device 2 under the squeezing of the garbage compression and recovery mechanism 8. As the partition plate 505 moves toward the side of the metal recovery device 2, the cavity on the side of the recyclable garbage will also be slightly compressed to a certain extent. The remaining features are the same as those in Example 1.

[0041] Example 3: Reference Figure 9, In order to protect the telescopic shaft in the box, the optical axis protection device 6 includes a protective base plate 600, which is fixedly installed in the main guide rail 500, and a spring 602 is fixedly installed in the protective base plate 600. A protective slide plate 601 is slidably installed in the protective base plate 600, and one end of the protective slide plate 601 is fixedly connected to the spring 602. Through the cooperation of the protective slide plate 601 and the spring 602, when the partition plate 505 is pushed toward the side of the metal recovery device 2 by the push plate 504, the push plate 504 will resist the protective slide plate 601 and slide into the protective base plate 600. When the protective slide plate 601 moves, the spring 602 is compressed. When the push plate 504 retracts and drives the partition plate 505 to move toward the side of the garbage compression and recovery mechanism 8, the spring 602 pushes the protective slide plate 601 under the elastic action. At this time, the protective slide plate 601 will always resist the push plate 504. The first multi-stage telescopic rod 502 is shielded by the protective slide plate 601 to prevent the garbage from scratching the first multi-stage telescopic rod 502. After the recycling is completed, when the recycled garbage needs to be released for cleaning, the garbage compression and recovery mechanism 8 is opened, and the partition plate 505 is pushed out by the first hydraulic cylinder 501 and the first multi-stage telescopic rod 502. As the partition plate 505 moves, the recycled general garbage can be pushed out, and the fixing bolts 506 and the partition plate 505 are removed. The compression carriage body 1 is pushed up by the hydraulic cylinder and hydraulic rod on the frame, and the compression carriage body 1 is rotated on the frame on the side close to the garbage compression and recovery mechanism 8. The compression carriage body 1 is lifted on the side close to the metal recovery device 2, which can make the compression carriage body 1 tilt, thereby pouring out the recyclable garbage, thereby realizing complete classified recycling and classified dumping functions. The remaining features are the same as those in Example 1.

[0042] Working principle: When in use, the compression compartment body 1 needs to be installed on the frame. When installing, the compression compartment body 1 is connected to the frame rotationally on the side close to the garbage compression and recovery mechanism 8, and each hydraulic cylinder is connected to the hydraulic system, and the electrical device is connected to the battery for power supply, and the bottom of the compression compartment body 1 is connected to the hydraulic push rod on the frame, so that the hydraulic cylinder on the frame can be used to rotate and lift the compression compartment body 1, thereby dumping all the garbage in the compression compartment body 1. When in use, the garbage compression and recovery mechanism 8 is the same as the compression and recovery structure and working principle of the existing compression-type garbage recycling vehicles on the market. When in use, the partition plate 505 is fixed to the push plate 504 through 206, and the first multi-stage telescopic rod 50 is moved by the first hydraulic cylinder 501. 2 is pushed out to the maximum distance. At this time, the partition plate 505 should be located near the side of the garbage compression and recycling mechanism 8. During recycling, the garbage in the ordinary garbage bin is compressed and recycled into the compression compartment body 1 through the garbage compression and recycling mechanism 8. The electromagnet 202 is energized to clamp the edge of the recyclable garbage bin on the claw 413. When the output shaft of the third hydraulic push rod 406 is extended, the output shaft of the third hydraulic push rod 406 drives the cover plate 403 to rotate based on the rotating shaft 402. When the cover plate 403 rotates, the recycling port 400 is exposed and the outer mounting frame 412 is driven to rise through the first connecting rod 404 and the second connecting rod 414. The rising of the outer mounting frame 412 drives the garbage bin to rise and resist against the card plate 411. The card plate 411 and the claw 413 cooperate to compress the garbage bin. The inner mounting frame 410 is clamped on the side of the trash can, and as the outer mounting frame 412 rises, the inner mounting frame 410 will also rise in the guide rail groove 408 through the guide column 409. Since the cover plate 403 is rotating and the outer mounting frame 412 needs to do an upward movement, the first connecting rod 404 and the second connecting rod 414 are connected in a rotating manner, so that the first connecting rod 404 rotates on the second connecting rod 414 when it rises to adapt to its movement trajectory. When the trash can is lifted to the top, it will be upside down on the recycling port 400, and the garbage in the trash can will fall into the compression compartment body 1. When falling in, since the electromagnet 202 is energized to generate strong magnetism, the metal garbage in the falling garbage will be attracted by the electromagnet 202 to the electromagnet 202, thereby separating the metal garbage and non-metal garbage. To separate the garbage, at the beginning of storage, since the compression compartment body 1 is relatively empty, the second multi-stage telescopic rod 306 can be extended by the second hydraulic cylinder 305, and the second multi-stage telescopic rod 306 pushes the auxiliary plate 302 to rotate, so that one end of the auxiliary plate 302 is close to the electromagnet 202, which can make the garbage closer to the side of the electromagnet 202 when falling, making it easier for the electromagnet 202 to attract metal garbage. The auxiliary plate 302 can be vibrated by cooperating with the small vibration motor 304, so that the auxiliary plate 302 can be used to shake the garbage apart. As the garbage on one side of the garbage compression and recovery mechanism 8 is recycled, the partition plate 505 will be pushed toward the side of the metal recovery device 2 under the squeezing of the garbage compression and recovery mechanism 8. As the partition plate 505 moves toward the side of the metal recovery device 2,It will also slightly compress the cavity on the side of the recyclable garbage to a certain extent. Through the cooperation of the protective slide plate 601 and the spring 602, when the partition plate 505 is pushed to the side of the metal recovery device 2 by the push plate 504, the push plate 504 will press against the protective slide plate 601 and slide into the protective base plate 600. When the protective slide plate 601 moves, it compresses the spring 602. When the push plate 504 retracts and drives the partition plate 505 to move to the side of the garbage compression and recovery mechanism 8, the spring 602 pushes the protective slide plate 601 under the elastic action. At this time, the protective slide plate 601 will always press against the push plate 504, and the protective slide plate 601 is used to block the first multi-stage telescopic rod 502 to prevent garbage from scratching the first multi-stage telescopic rod. After recycling is complete, when it is time to release and clean the recycled garbage, the garbage compression and recycling mechanism 8 is opened. The first hydraulic cylinder 501 and the first multi-stage telescopic rod 502 push out the partition plate 505. As the partition plate 505 moves, the recycled general garbage is pushed out. The fixing bolts 506 and the partition plate 505 are removed. The compression carriage body 1 is pushed up by the hydraulic cylinder and hydraulic rod on the frame. The side of the compression carriage body 1 near the garbage compression and recycling mechanism 8 rotates on the frame.
