Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of garbage trucks, in particular to a garbage truck box with compression function and a garbage truck. BACKGROUND

[0002] Most of the garbage collection and transportation vehicles with garbage compression function on the market are compression garbage trucks that use tail loading and filler compression. A few are self-loading and unloading garbage trucks with only mild compression function.

[0003] In order to improve the loading capacity of the garbage box, the existing compression garbage truck needs to improve the compression ratio of the garbage in the garbage box. Therefore, a large filler device is arranged at the tail of the garbage box to squeeze and fill the collected bulk garbage into the garbage box for storage. Due to the large size and complex structure of the filler, it almost occupies half of the mass of the vehicle, which usually causes the center of gravity of the whole vehicle to be biased to the rear, the load of the rear axle to be biased to be large, and the risk of tilting to be high when the filler is lifted for unloading. At the same time, the large filler also greatly lengthens the rear suspension of the vehicle, reduces the ground clearance of the rear of the vehicle, and results in low passing performance of the vehicle. The self-loading and unloading garbage truck with side loading uses a way of loading on the front side of the garbage box. However, the push shovel arranged in the garbage box can only push the garbage accumulated at the front end of the garbage box backward to ensure that the garbage box is filled with garbage as much as possible, and cannot continuously provide squeezing force to the garbage. Therefore, the loading capacity of the garbage box is weak, and the garbage in the box can only be lightly compressed.

[0004] As disclosed in patent CN116216126A, a garbage compression compartment for hook arm garbage truck and garbage transfer truck, the compartment body cavity includes a device cavity arranged near the front end, and a garbage compression cavity near the rear end. A push shovel that can move longitudinally and reciprocally is arranged between the device cavity and the garbage compression cavity. The garbage compression cavity is in communication with the garbage inlet and the discharge door. An oil cylinder assembly for pushing forward or returning to the garbage compression cavity is arranged in the device cavity to push the push shovel to compress the garbage in the garbage compression cavity or push the garbage out of the discharge door and return after completion. The garbage enters the box and is directly pushed to the garbage compression cavity, which is the garbage storage cavity, and the garbage cannot be fully compressed, and the loading capacity of the garbage box is relatively weak. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a garbage truck box with compression function and a garbage truck, which can effectively improve the loading capacity of the garbage box.

[0006] In order to solve the above technical problems, the technical scheme adopted by the present application is: A garbage truck box with compression function, comprising a garbage box body, a feeding port is arranged on the garbage box body, a tail door is arranged at the tail of the garbage box body, a compression bin and a garbage storage bin are arranged in the garbage box body, a compression and pushing structure for compressing the incoming garbage and pushing the compressed garbage into the garbage storage bin is arranged corresponding to the compression bin, a movable unloading push shovel is arranged in the garbage storage bin corresponding to the compression bin, and an openable and closable window is arranged on the unloading push shovel corresponding to the compression bin.

[0007] Further or preferably: A material guiding structure is arranged in the garbage box body corresponding to the feeding port, the material guiding structure is located above the compression bin, and a push shovel driving device bin is arranged below the compression bin.

[0008] The compression and pushing structure is arranged corresponding to the front part of the compression bin, the compression push head of the compression and pushing structure is located in the compression bin, and the compression push head and the window are aligned to form a compression cavity with both ends sealed.

[0009] The compression bin and the garbage storage bin are arranged in a longitudinal staggered manner along the garbage truck.

[0010] The front end of the garbage box body is provided with an inspection cabin door corresponding to the compression and pushing structure and the push shovel driving device bin.

[0011] The compression bin is a channel structure arranged in a longitudinal direction along the garbage truck; in the initial state, the unloading push shovel is arranged in close contact with the outlet end of the channel structure.

[0012] A door hole is arranged on the unloading push shovel corresponding to the outlet end of the compression bin, a movable door is arranged on the unloading push shovel and can move to the door hole position, and a driving structure is arranged for driving the movable door.

[0013] A pair of slide rail structures are arranged vertically on the unloading push shovel, the door hole is located between the pair of slide rail structures, a sliding groove is arranged on the inner side of the slide rail structure, and the edge of the movable door is located in the corresponding sliding groove.

[0014] The lower part of the unloading push shovel is an inclined structure, the driving structure is a hydraulic oil cylinder, the hydraulic oil cylinder is arranged in the inclined structure or outside the slide rail structure, and the piston rod of the hydraulic oil cylinder extends into the sliding groove and is connected to the bottom side of the movable door edge.

[0015] A garbage truck, comprising a chassis and a garbage truck box with compression function arranged on the chassis.

[0016] Compared with the prior art, the present application has the following advantages: The garbage truck box with compression function and the garbage truck structure are reasonable in design. The garbage is first introduced into the compression bin in the box through the inlet on the box, and then is compressed. After compression, the window on the unloading push shovel is opened, and the garbage behind the push shovel is pushed into the space in the garbage box through the window. When the garbage box is filled with loose garbage, the huge pushing force of the compression push head continues to squeeze the collected garbage into the garbage box, forcing the garbage in the garbage box to be further compacted until the garbage box is full, and then the compression push head stops working. Then the window on the unloading push shovel is closed, and the unloading push shovel pushes the garbage in the garbage box backward during unloading. The loading capacity of the garbage box can be effectively improved. BRIEF DESCRIPTION OF DRAWINGS

[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0027] Although the invention has been shown and described herein with reference to specific embodiments, it is not intended to be limited to the details shown. Rather, various modifications in detail may be made within the equivalent scope and scope of the claims without departing from the invention. In the drawings, the same item numbers refer to the same elements.

[0028] Throughout this disclosure, various terms are used to describe the physical shape or arrangement of features. Many of these terms are used to describe features conforming to a cylindrical or generally cylindrical geometry with the feature as its radius and a central axis perpendicular to that radius. Unless otherwise specified, the terms are given the following meanings: The terms “longitudinal,” “longitudinal,” “axial,” and “axial” refer to a direction, dimension, or orientation parallel to the central axis. The terms “radial” and “radially” refer to a direction, dimension, or orientation perpendicular to the central axis. The terms “inward” and “inner” refer to a direction, dimension, or orientation extending radially toward the central axis. The terms “outward” and “outer” refer to a direction, dimension, or orientation extending radially away from the central axis.

[0029] In this specification, relative terms such as “horizontal,” “vertical,” “upward,” “downward,” “top,” and “bottom,” and their derivatives (e.g., “horizontal,” “downward,” “upward,” etc.) should be interpreted as referring to the direction described or the direction shown in the accompanying drawings. These relative terms are for ease of description and are not generally intended to require a specific direction.

[0030] like Figures 1 to 8 As shown, the garbage truck container with compression function includes a garbage container body, a feeding port on the garbage container body, a feeding port cover corresponding to the feeding port, a tail door at the rear of the garbage container body, the top of the tail door being hinged to the top of the rear port of the garbage container body, and a driving hydraulic cylinder for driving the tail door to flip open on the top of the garbage container body.

[0031] The main body of the garbage bin has a compression chamber and a garbage storage chamber. The compression chamber is equipped with a compression pushing structure for compressing the garbage and pushing the compressed garbage into the garbage storage chamber. The garbage storage chamber is equipped with a movable unloading pusher next to the compression chamber, and the unloading pusher is equipped with an openable and closable window corresponding to the compression chamber.

[0032] This invention features a rational structural design. Garbage enters the compression chamber inside the container through the inlet on the container body for compression. After compression, the window on the unloading pusher opens, and the garbage is pushed into the garbage bin space behind the pusher through the window. When the garbage bin is filled with loose garbage, the huge thrust of the compression pusher continues to squeeze the collected garbage into the garbage bin, forcing the garbage inside the garbage bin to be further compacted until the garbage bin is full. Only then does the compression pusher stop working, and the window on the unloading pusher closes. During unloading, the unloading pusher pushes the garbage out of the garbage bin backward. This effectively improves the loading capacity of the garbage bin.

[0033] The feed inlet is located at the front top of the garbage bin body. Inside the garbage bin body, corresponding to the feed inlet, there is a material guiding structure. The material guiding structure is located above the compression chamber. The material guiding structure is a hopper structure that is larger at the top and smaller at the bottom. The hopper structure is equipped with an inclined guide plate to facilitate the smooth entry of garbage into the compression chamber. Below the compression chamber is the pusher drive equipment chamber, with the compression push structure located in front of the compression chamber and above the pusher drive equipment chamber. The compression chamber and the garbage storage chamber are staggered along the longitudinal direction of the garbage truck. That is, the main body of the garbage container is divided into two areas along the longitudinal direction: the front area and the rear area. The material guiding structure, compression chamber, compression push structure, and pusher drive equipment chamber are all located in the front area, while the rear area forms the garbage storage chamber, which is reasonably arranged. The material guiding structure, compression chamber, compression push structure, and pusher drive equipment chamber are all integrated in the front area, resulting in a compact structure.

[0034] The compression push structure is set at the front of the compression chamber. The compression push head of the compression push structure is located inside the compression chamber. When the compression push head and the window are aligned, a compression cavity with sealed ends is formed. The garbage entering the compression chamber can be compressed by the compression push head. After the window is opened, the compressed garbage is pushed into the garbage storage chamber by the compression push head.

[0035] The front of the main body of the garbage bin is equipped with maintenance doors for the compression and push structure and the pusher drive equipment compartment, which facilitates the maintenance of the drive equipment inside the main body of the garbage bin.

[0036] The compression chamber is a channel structure arranged longitudinally along the garbage truck; in the initial state, the unloading pusher is fitted against the outlet end of the channel structure. The unloading pusher has a door opening corresponding to the outlet end of the compression chamber, and the unloading pusher has a movable door that can be moved to the door opening position and a drive structure for driving the movable door.

[0037] like Figures 6 to 8 As shown, the unloading pusher is equipped with a pair of vertically arranged sliding rail structures. The door opening is located between the pair of sliding rail structures. The inner side of the sliding rail structure is provided with a sliding groove, and the edge of the sliding door is located in the corresponding sliding groove. Preferably, the sliding rail structure is a vertically arranged channel steel, and the edge of the sliding door is provided with rollers or sliders. The rollers or sliders are located in the rail groove of the channel steel, which can bear a large longitudinal pressure and ensure stable and reliable operation.

[0038] The lower part of the unloading pusher is an inclined structure, and the driving structure is a hydraulic cylinder. The hydraulic cylinder is located inside the inclined structure or outside the slide rail structure. The piston rod of the hydraulic cylinder extends into the slide groove and is connected to the bottom of the side of the moving door. The moving door is driven up and down by the hydraulic cylinder, and the opening and closing of the window on the unloading pusher is easy to control.

[0039] The present invention provides a garbage truck, comprising a chassis and a garbage container with a compression function, the main body of the garbage container being mounted on the chassis; the garbage truck has a strong loading capacity.

[0040] This invention relates to a compression garbage truck body with a compression function, mainly comprising a garbage container body, a pusher compression structure, an unloading pusher, and a sealed tail door. The front top of the garbage container body has a feed inlet with a covered door, below which is the garbage compression chamber, and the front of the garbage compression chamber is equipped with a compression pusher structure. The unloading pusher is positioned inside the garbage container, behind the tail outlet of the compression chamber. A sealed sliding door that can be slid open upwards is located in the middle of the unloading pusher, the size and shape of which correspond one-to-one with the tail outlet of the compression chamber. A sealed tail door that can be rotated upwards and opened is located at the rear of the garbage container.

[0041] After the inlet cover at the front of the waste bin is opened, the feeding mechanism can dump the waste from the bin into the compression chamber at the bottom of the inlet. Then, the compression pusher head installed at the front of the compression chamber moves backward, pushing the waste in the compression chamber backward. The sliding door on the unloading pusher is in the upward sliding open position, with the pusher door opening close to the compression chamber. The waste pushed by the compression pusher head enters the waste bin space behind the pusher through the door opening. When the waste bin is full of loose waste, the huge thrust of the compression pusher head continues to squeeze the collected waste into the waste bin, forcing the waste in the waste bin to be further compacted until the waste bin is full. Only then does the compression pusher head stop working, and then the door opening on the unloading pusher head closes downward under the pusher's hydraulic cylinder, sealing the door opening on the pusher head. Next, after the vehicle arrives at the waste treatment plant, the vehicle's sealed tailgate first rotates upward to open, then the unloading pusher head pushes backward to push the waste in the waste bin out. After the pushing is completed, the pusher head returns to its original position, the tailgate rotates downward to close and lock, completing the unloading operation.

[0042] This invention eliminates the rear stuffer and installs a compression pusher at the front of the garbage bin to achieve powerful compression of the garbage inside, optimizing the axle load distribution and effectively preventing the risk of the vehicle nose-up during unloading. It also reduces the overall length of the vehicle, increases the departure angle, and optimizes its passability. The width of the garbage bin's inlet is much smaller than that of a conventional stuffer, and the sealed cover effectively prevents odors from escaping from the garbage inside the bin and prevents garbage from flying at the inlet.

[0043] A preferred embodiment of the present invention is as follows: This invention provides a compressed garbage truck body with compression function, mainly including a garbage container body 1.1, an inspection hatch 1.2, an inlet cover 1.3, a tailgate structure 1.4, a pusher cylinder 1.5, a compression pusher 1.6, a pusher cylinder 1.7, and an unloading pusher 1.8, etc.

[0044] The main body of the garbage bin 1.1 is mainly composed of the garbage bin shell 1.1.1, the feed inlet 1.1.2, the guide plate 1.1.3, the compression chamber 1.1.4, the pusher cylinder seat 1.1.5, the garbage bin base frame 1.1.6, the front compartment partition 1.1.7, the maintenance window 1.1.8, the front wall panel 1.1.9, and the rear frame 1.1.10. The garbage bin shell 1.1.1 is mainly composed of a bottom plate and side plates, and its overall cross-section is rounded and rectangular. A front wall panel 1.1.9 is located at the front end of the garbage bin shell 1.1.1, and the front wall panel 1.1.9 has maintenance windows 1.1.8 arranged in a triangular pattern for installing and maintaining the components inside the garbage bin. At the bottom of the garbage bin shell 1.1.1, there is a garbage bin base frame 1.1.6 for supporting and fixing the garbage bin shell 1.1.1. The base frame consists of two longitudinal beams and multiple transverse beams. At the top front end of the garbage bin shell 1.1.1, there is a feed inlet 1.1.2. The feed inlet 1.1.2 is a four-sided enclosed, top-to-bottom open structure, with the right side lower and the other three sides higher, to prevent garbage from scattering when it is disposed of. At the lower rear side of the feed inlet 1.1.2, there is a front compartment partition 1.1.7, and the other three sides are equipped with guide plates 1.1.3. The front compartment partition and the guide plates together form a four-sided enclosed material guiding structure, which is used to guide the garbage disposed of from the feed inlet 1.1.2 into the compression chamber 1.1.4 below the guide plates 1.1.3. The compression chamber 1.1.4 is used to compress the garbage poured in from the feed inlet 1.1.2 into the space at the rear of the garbage bin for storage. Its main body is a rectangular structure with openings at the front and rear, welded from thick steel plates. One side of the top of the cuboid has a material discharge window, while the other three sides are closed. A pusher cylinder seat for mounting the pusher cylinder 1.5 is located at the front of the compression chamber. A pusher cylinder seat 1.1.5 is located inside the front wall panel 1.1.9, below the compression chamber 1.1.4. The space below the compression chamber 1.1.4 serves as the installation space for the pusher cylinder 1.7 and a wastewater storage space. A rear frame 1.1.10 is located at the rear of the garbage bin shell 1.1.1 for mounting the sealing tailgate mechanism 1.4.

[0045] The upper part of the feed inlet 1.1.2 is equipped with an automatically opening and closing feed inlet cover 1.3, and a sealing strip is installed around the feed inlet cover 1.3. After the feed inlet cover 1.3 is opened, garbage can be dumped into the feed inlet 1.1.2; after the feed inlet cover 1.3 is closed, the feed inlet 1.1.2 can be completely sealed, preventing loose lightweight garbage in the feed inlet 1.1.2 from being blown away by the wind and preventing odors from the garbage bin from drifting outward.

[0046] A removable maintenance hatch 1.2 is installed on the maintenance window 1.1.8 for installing and maintaining components inside the trash can and preventing wastewater from overflowing from the maintenance window 1.1.8.

[0047] The unloading pusher includes a vertically set vertical frame structure and a vertical steel plate. The edge of the vertical steel plate is equipped with a rubber plate 1.8.3, which makes the structure stable and reliable. The frame structure is connected to the pusher cylinder. The side of the garbage bin is equipped with a longitudinal guide rail structure that cooperates with the unloading pusher. The unloading pusher pushes the garbage unloading stably and reliably.

[0048] The unloading pusher 1.8 is equipped with a pair of vertically arranged sliding rail structures. The doorway and the sliding door 1.8.1 are both located between the pair of sliding rail structures. The inner side of the sliding rail structure is provided with a sliding groove, and the edge of the sliding door is located in the corresponding sliding groove. Preferably, the sliding rail structure is a vertically arranged channel steel, and the edge of the sliding door is provided with rollers or sliders. The rollers or sliders are located in the rail groove of the channel steel, which can bear a large longitudinal pressure and ensure stable and reliable operation.

[0049] The lower part of the unloading pusher is an inclined structure, and the driving structure is a hydraulic cylinder 1.8.2. The hydraulic cylinder is located on the outside of the slide rail structure, and the side of the channel steel has an opening. The lower end of the piston rod of the hydraulic cylinder is connected to the slider in the slide rail structure through the opening, which makes the structure compact. The moving door is driven up and down by the hydraulic cylinder, and the opening and closing of the window on the unloading pusher is easy to control.

[0050] The back of the unloading pusher is a frame structure. The frame structure has a step corresponding to the port of the compression chamber. There is a rubber strip 1.8.4 inside the step. By cooperating with the port of the compression chamber, the unloading pusher and the port of the compression chamber can be kept close together, preventing garbage from entering the back of the pusher.

[0051] A compression pusher 1.6 is installed at the front end of the compression chamber 1.1.4. The compression pusher 1.6 is connected to the pusher cylinder seat by two vertically arranged pusher cylinders 1.5. The compression pusher 1.6 is initially located at the front of the compression chamber 1.1.4. When garbage is poured into the feed inlet 1.1.2, the piston rod of the pusher cylinder 1.5 extends, driving the compression pusher 1.6 to slide backward and squeeze the garbage backward. Then, the piston rod of the pusher cylinder 1.5 retracts, pulling the compression pusher 1.6 back to its initial position. This action is repeated continuously, continuously compressing the collected garbage into the space at the rear of the garbage bin body 1.1. When the loose garbage fills the space at the rear of the bin body 1.1, the compression pusher 1.6 continues to compress the garbage inward, further compacting the garbage in the rear space until the garbage in the garbage bin reaches the set compression ratio. Only then will the vehicle stop feeding garbage, stop compression, and the compression pusher 1.6 retract to the front of the compression chamber 1.1.4.

[0052] The unloading pusher 1.8 is installed in the garbage bin space at the rear of the compression chamber 1.1.4 and is connected to the pusher cylinder seat 1.1.5 via the pusher cylinder 1.7. A small door is located in the middle of the unloading pusher 1.8 to allow garbage from the compression chamber 1.1.4 to pass through. When the pusher cylinder 1.7 is not in operation, the door opening of the unloading pusher 1.8 is flush against the rear end of the compression chamber 1.1.4, and the small door slides upwards to open, allowing the garbage to be smoothly compressed into the space behind the pusher. When the garbage in the bin reaches the set compression ratio, the garbage truck stops loading, and the small door on the unloading pusher 1.8 slides downwards under the push of the hydraulic cylinder, squeezing out the garbage until the pusher door opening closes. After the garbage truck arrives at the waste treatment plant, the sealing tailgate mechanism 1.4 first rotates upwards to open, then the piston rod of the pusher cylinder 1.7 extends to push the unloading pusher 1.8 backwards, pushing the garbage stored in the bin out. Then, the sealing tailgate mechanism 1.4 closes and locks, completing the unloading operation.

[0053] The sealed tailgate mechanism 1.4 consists of a tailgate body, sealing strip, flipping mechanism, locking mechanism, etc., and is installed on the rear frame 1.1.10. It is used to cooperate with the compression pusher 1.6 to squeeze the garbage in the garbage bin, while preventing the garbage and sewage in the garbage from leaking from the rear of the garbage bin body 1.1. It also opens actively during unloading without obstructing the garbage from being pushed out.

[0054] The above description is merely an illustration of preferred embodiments of the present invention, and the above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0055] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
