Description

Technical Field

[0001] This invention relates to a composite device of a garbage truck's bin-lifting mechanism and rear cover, belonging to the field of special vehicle technology. Background Technology

[0002] Food waste trucks are primarily used for the collection, storage, and transportation of food waste. The bin-lifting mechanism is one of the most frequently used components in the operation of food waste trucks. With increasingly stringent emission and noise requirements, the demand for new energy chassis is growing. However, most new energy chassis on the market place the battery behind the front of the vehicle or on the sides. In existing technology, food waste trucks typically place the garbage inlet on the roof near the front of the vehicle. This necessitates placing the bin-lifting mechanism on the side behind the front of the vehicle. To ensure the vehicle doesn't exceed the width limit, this structure requires a recessed design. Since the batteries in existing new energy chassis are also located in the same position—behind the front or on the side—this creates a conflict, limiting the use of fewer batteries and reducing the battery capacity of special vehicles. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned technology and provide a device that places the bucket lifting mechanism at the rear and combines the bucket lifting mechanism with the rear cover, thereby avoiding occupying battery space.

[0004] To solve the above-mentioned technical problems, the technical solution proposed by this invention is: a composite device for a garbage truck's bin-lifting mechanism and rear cover, comprising: a rear cover, a guide rail, a baffle, and a bin-lifting mechanism; the rear cover covers the rear opening of the garbage truck with its top hinged to the top of the garbage truck, and is capable of closing the rear opening of the garbage truck; the guide rail is arranged on the outer surface of the rear cover and extends to the roof of the truck; the baffle and the bin-lifting mechanism have sliders that cooperate with the locking guide rail, allowing both to move along the guide rail; the roof has a lifting cylinder; the lifting cylinder drives a rotating frame; one end of the rotating frame is hinged to the roof, and the other end is connected to the bin-lifting mechanism via a connecting arm; the bottom of the rotating frame has a top cover capable of closing the garbage opening on the roof; the portion of the guide rail on the roof has branch tracks; the side of the portion of the guide rail outside the rear cover has a first locking mechanism; the first locking mechanism is capable of moving back and forth between two positions: one that blocks the baffle and the bin-lifting mechanism, and another that does not block the movement of the baffle and the bin-lifting mechanism along the guide rail.

[0005] A further improvement to the above solution is that when the lifting cylinder drives the rotating frame to open the top cover, if the first locking mechanism is in a position that does not obstruct the movement of the baffle and the bucket lifting mechanism along the guide rail, the rotating frame drives the bucket lifting mechanism to move along the guide rail toward the roof of the vehicle through the connecting arm, and the bucket lifting mechanism pushes the baffle to move synchronously; when the baffle reaches the end of the guide rail located on the roof of the vehicle, the bucket lifting mechanism reaches the branch rail, and as the lifting cylinder continues to move, the bucket lifting mechanism continues to move along the branch guide rail; the branch guide rail is an arc that curves toward the garbage opening on the roof of the vehicle, and with the end of the guide rail located on the roof of the vehicle as the center, the bucket lifting mechanism moves along the branch guide rail, causing the bucket lifting mechanism to perform a flipping action.

[0006] A further improvement to the above solution is that when the lifting cylinder drives the rotating frame to open the top cover, if the first locking mechanism is in a position that blocks the baffle and the bucket lifting mechanism from moving along the guide rail, the rotating frame drives the bucket lifting mechanism to move along the guide rail toward the roof of the vehicle through the connecting arm, and the bucket lifting mechanism pushes the baffle to move synchronously; when the baffle reaches the first locking mechanism, as the lifting cylinder continues to move, the bucket lifting mechanism transmits power to the guide rail in sequence through the baffle and the first locking mechanism, and the guide rail drives the rear cover to rotate along its hinge point, thereby opening the rear opening of the garbage truck.

[0007] A further improvement to the above solution is that the rear cover and the vehicle body can be locked or unlocked by the action of the second locking mechanism.

[0008] A further improvement to the above solution is that the garbage truck has a ramp inside, with the high position of the ramp located below the garbage opening on the roof and the low position located at the front end of the garbage truck.

[0009] A further improvement to the above solution is that the front end of the garbage truck has a push plate that can push the garbage inside the truck toward the parking space.

[0010] The present invention provides a composite device for a garbage truck's bin lifting mechanism and rear cover, which solves the problem of traditional bin lifting mechanisms occupying the side space of the vehicle. In particular, it solves the problem of reduced battery capacity caused by the bin lifting mechanism occupying the side space of the chassis when using a new energy chassis with side-mounted batteries. By placing the bin lifting mechanism at the rear and forming a composite device with the rear cover, sharing the same hydraulic system, it can realize both lifting of the garbage bin and opening and closing of the rear cover, reducing the complexity of the hydraulic system.

Detailed Implementation

[0017] Example: The combined device of the garbage truck's bin-lifting mechanism and rear cover in this example, such as... Figure 1 and Figure 2 As shown, the system includes: a rear cover 1, a guide rail 2, a baffle 11, and a bucket-lifting mechanism 6. The rear cover 1 covers the rear opening of the garbage truck body 21 with its top hinged to the top of the garbage truck, and is capable of closing the rear opening of the garbage truck body 21. The guide rail 2 is arranged on the outer surface of the rear cover 1 and extends to the roof of the truck. The guide rail is arranged in the form of two symmetrical tracks. The baffle 11 and the bucket-lifting mechanism 6 have sliders that cooperate with the locking guide rail 2, allowing both to move along the guide rail 2. The roof has a lifting cylinder 17; the lifting cylinder 17 drives a rotating frame 14; one end of the rotating frame 14 is hinged to the roof of the truck, and the other end is connected to the bucket-lifting mechanism 6 via a bucket-lifting rod 12. The bottom of the rotating frame 14 has a top cover capable of closing the garbage opening on the roof of the truck. The portion of the guide rail 2 on the roof has branch tracks; the side of the portion of the guide rail 2 outside the rear cover 1 has a first locking cylinder 4; the guide rail 2 has corresponding holes to accommodate the piston rod 3 of the first locking cylinder 4, so that as the first locking cylinder 4 moves, the piston rod 3 can pass through the guide rail, thereby blocking the baffle 11 and the bucket lifting mechanism 6 from moving along the guide rail 2; or, the piston rod 3 of the first locking cylinder retracts, without blocking the baffle 11 and the bucket lifting mechanism from moving along the guide rail 2; the first locking cylinder 4 is arranged at a position slightly above the middle in the height direction of the rear cover 1, and the first locking cylinder 4 is arranged symmetrically in groups of two, located outside the guide rail 2 and fixed to the rear cover 1.

[0018] The rear cover 1 and the garbage truck body 21 have symmetrical locking ears. The piston rod of the second locking cylinder 22 can pass through the locking ears. In this way, the rear cover 1 and the garbage truck body 21 can be locked or unlocked by the action of the second locking cylinder 22.

[0019] The bin-lifting mechanism 6 includes a hanging rack for hanging the trash can and a flip plate 8 for abutting the trash can. The hanging rack is the main moving part of the bin-lifting mechanism 6, which slides with the guide rail 2 and is connected to the bin-lifting rod 12. The flip plate 8 is rigidly connected to the hanging rack.

[0020] The combined device of the garbage truck's bin-lifting mechanism and rear cover in this embodiment has two working modes. The first mode is garbage collection. Specifically: the garbage bin 9 is hung on the bin-lifting mechanism 6, then the lifting cylinder 17 is activated, the piston rod 16 of the lifting cylinder extends, driving the rotating frame 14 to rotate, thereby opening the top cover. At this time, the piston rod 3 of the first locking cylinder 4 retracts, not obstructing the movement of the baffle 11 and the bin-lifting mechanism along the guide rail 2. The rotating frame 14 drives the bin-lifting mechanism 6 to move along the guide rail 2 towards the top of the truck through the bin-lifting pull rod 12. The bin-lifting mechanism 6 pushes the baffle 11 to move synchronously. When the baffle 11 reaches the position of the guide rail 2 on the truck... When the garbage bin 9 reaches the top end, the lifting mechanism 6 reaches the branch track. As the lifting cylinder 17 continues to move, the lifting mechanism 6 continues to move along the branch guide rail 2. The branch guide rail 2 is an arc-shaped structure curving towards the garbage opening on the roof, with the end of the guide rail 2 located on the roof as its center. Thus, the baffle 11 and the lifting mechanism 6 begin to rotate, and the lifting mechanism 6 moves along the branch guide rail 2. The lifting mechanism 6 performs a flipping action, emptying the contents of the garbage bin 9 from the garbage opening on the roof into the garbage truck body 21. Figure 3 As shown; then, the lifting cylinder 17 reverses its movement, the lifting cylinder piston rod 16 retracts, and the other components return along the guide rail 2, completing the garbage collection.

[0021] During this process, in order to ensure that the rear cover is tightly sealed, the piston rod of the second locking cylinder 22 extends to lock the rear cover 1 to the garbage truck body 21.

[0022] The second method involves opening the rear cover. Specifically: the piston rod of the second locking cylinder 22 retracts, unlocking the rear cover 1 from the garbage truck body 21; the piston rod 3 of the first locking cylinder 4 extends, positioning the baffle 11 and the bucket lifting mechanism along the guide rail 2; the lifting cylinder 17 actuates, extending its piston rod 16 and driving the rotating frame 14 to rotate. The rotating frame 14, through the bucket lifting rod 12, drives the bucket lifting mechanism 6 to move along the guide rail 2 towards the roof of the truck. The bucket lifting mechanism 6 pushes the baffle 11 to move synchronously; when the baffle 11 reaches the position of the first locking cylinder 4, as the lifting cylinder 17 continues to actuate, the bucket lifting mechanism 6 transmits power to the guide rail 2 sequentially through the baffle 11 and the piston rod 3 of the first locking cylinder. The guide rail 2 is then fixed to the rear cover 1, causing the rear cover 2 to rotate along its hinge point, thereby opening the rear opening of the garbage truck; thus, the action of opening the rear cover is completed. Figure 4 As shown, the garbage can be unloaded from the garbage truck body 21. After that, the lifting cylinder 17 moves in the opposite direction, the lifting cylinder piston rod 16 retracts, and the other components move in the opposite direction to close the rear cover 1 again.

[0023] The garbage truck body 21 has a ramp 18 inside. The higher part of the ramp 18 is located below the garbage opening on the roof, and the lower part is located at the front end of the garbage truck body 21. In this way, the garbage poured in through the garbage opening on the roof will slide down to the front end of the garbage truck body 21. Then, a pusher plate 19 located at the front end of the garbage truck body 21 pushes it towards the rear end of the garbage truck body 21. This not only prevents garbage from piling up in one place, but also compresses it to a certain extent, thereby saving space. The pusher plate 19 can also directly push the garbage out during garbage unloading operations. The pusher plate 19 is driven by a pusher plate cylinder 20.

[0024] The functions of the first and second locking cylinders in the composite device of the garbage truck's bucket lifting mechanism and rear cover in this embodiment can be fully realized by other similar functional components, such as electromagnetic actuators, pneumatic mechanisms, or even manual latches.

[0025] This invention is not limited to the specific technical solutions described in the above embodiments. Besides the above embodiments, this invention may have other implementation methods. All technical solutions formed by equivalent substitutions are within the scope of protection claimed by this invention.
