Description

Technical Field

[0001] This utility model relates to the technical field of garbage transport vehicles, specifically a garbage truck with a detachable compartment. Background Technology

[0002] Garbage trucks are specialized vehicles used by municipal sanitation departments to transport various types of garbage. They are mainly used for transporting various types of garbage in municipal sanitation departments and large factories and mines, and are especially suitable for transporting household garbage in residential areas. Urban populations are concentrated, and the amount of garbage generated every day is very large. However, urban land is limited, and timely garbage disposal is a major problem. The emergence of garbage trucks can help sanitation workers to clean up garbage in a timely manner, greatly reducing the workload of sanitation workers and alleviating the problem of urban garbage accumulation.

[0003] The existing Chinese utility model patent with publication number CN214123335U discloses a detachable garbage truck, belonging to the field of garbage truck technology. It includes a cab, chassis, and energy storage components. The chassis is connected to the cab; the energy storage components are connected to the chassis and are adjacent to the cab; the hook assembly is connected to the chassis and electrically connected to the energy storage components. The hook assembly is configured to be detachably connected to an external garbage compartment. This utility model provides a detachable garbage truck solution. This solution, through the pure electrification of the detachable garbage truck, eliminates many components of the original hydraulic system, resulting in a simplified structure and reduced malfunctions. Electric vehicles have lower operating costs than fuel-powered vehicles, significantly reduce noise and eliminate emissions pollution, and are energy-saving and environmentally friendly.

[0004] When loading and unloading garbage containers, the aforementioned detachable garbage trucks require adjusting the position of the containers using a pull arm. Since the pull arm is connected to the chassis and its rotation axis coincides with the chassis, the length of the garbage container cannot exceed the rotation axis of the pull arm. Otherwise, the rear of the garbage container will damage the chassis during the dumping process. Therefore, an electric push rod is needed to move the pull arm to the rear of the truck, and dumping takes a relatively long time. At the same time, during transportation, the weight of the garbage inside the container directly affects the garbage truck, and the vehicle's load-bearing capacity directly affects the weight of garbage that can be loaded and unloaded. Furthermore, the length of the front and rear wheelbase of the tractor affects its turning radius. To prevent the tractor's turning radius from being too large and to maintain the overall center of gravity, the container generally does not extend too far beyond the rear wheels of the tractor. This results in a limitation on the volume of the existing garbage truck container and a low single-trip transport capacity. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a detachable garbage truck, which solves the problems of low single-trip transport capacity and time-consuming garbage dumping.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: A detachable garbage truck includes a tractor unit, characterized in that: a connecting base is fixedly installed on the top of the tractor unit, a lifting piston is movably installed on the top of the connecting base, a transmission frame is movably installed on the rear side of the lifting piston, a limiting electric push rod is fitted at the rear end of the transmission frame, a limiting shaft is fixedly installed at the movable end of the limiting electric push rod, a connecting electric push rod is fixedly installed inside the transmission frame, a positioning tooth is fixedly installed at the movable end of the connecting electric push rod, a storage mechanism is installed on the top of the transmission frame for storing garbage, and a support mechanism is installed on the rear side of the tractor unit;

Beneficial effects

[0014] This utility model provides a garbage truck with a detachable compartment. Compared with the prior art, it has the following advantages:

[0015] (1) The detachable garbage truck, through the setting of the limiting electric push rod, when the limiting electric push rod drives the limiting shaft to move, so that the limiting shaft is inserted into the opening structure at the rear end of the tractor chassis, the rotation axis of the transmission frame coincides with the axis of the limiting shaft, and can push the tooth structure of the positioning tooth into the interior of the positioning rod through the connecting electric push rod, restricting the position between the container and the transmission frame, thereby restricting the position of the container during transportation. When dumping garbage, the supporting electric push rod at the rear end of the container supports the rear end of the container, so that the supporting wheel is lifted off the ground, and the limiting electric push rod retracts to unlock the transmission frame. Then, the lifting piston drives the transmission frame and the container to rotate around the contact point between the bottom end of the supporting electric push rod at the rear end of the container and the ground to dump garbage. This method can restrict the position of the container during transportation while reducing the operation of moving the transmission frame through the electric push rod, thereby saving the time required for dumping garbage.

The connecting column is rotatably connected to the limiting base through a bearing. The upper front and rear sides of the connecting column have protruding structures. The protruding structures of the connecting column are located between the protruding structures on both sides of the upper top of the limiting base. The limiting base can limit the rotation angle of the connecting column so that the support wheel can generate an angle opposite to the front wheel of the tractor when turning, thereby reducing the turning radius. The support wheel can support the rear end of the container, share the weight of the garbage carried by the tractor, and reduce the turning radius to increase the single load capacity.

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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a detachable garbage truck includes a tractor 1, a connecting base 11 fixedly installed above the tractor 1, a lifting piston 12 movably installed above the connecting base 11, a transmission frame 13 movably installed on the rear side of the lifting piston 12, a limiting electric push rod 14 fitted at the rear end of the transmission frame 13, a limiting shaft 15 fixedly installed at the movable end of the limiting electric push rod 14, a connecting electric push rod 16 fixedly installed inside the transmission frame 13, a positioning tooth 17 fixedly installed at the movable end of the connecting electric push rod 16, and a bottom of the lifting piston 12... The transmission frame 13 is rotatably connected to the tractor 1 via the connecting base 11. The transmission frame 13 has raised structures on the upper left and right sides. The top of the transmission frame 13 is rotatably connected to the top of the lifting piston 12. The transmission frame 13 is fitted onto the chassis of the tractor 1. The rear end of the chassis of the tractor 1 has a cylindrical opening that fits into the limiting shaft 15. The limiting shaft 15 is mirror-symmetrically installed on the left and right sides of the rear end of the transmission frame 13 via the limiting electric push rod 14. The positioning teeth 17 are mirror-symmetrically installed inside the raised structures on the left and right sides of the front of the transmission frame 13 via the connecting electric push rod 16.

[0024] Specifically, the tractor 1 can move the housing 21. The connecting base 11 can restrict the position of the bottom end of the lifting piston 12. The top end of the transmission frame 13 is rotatably connected to the top end of the lifting piston 12. The elevation angle of the transmission frame 13 can be adjusted by the extension and retraction of the lifting piston 12. When the limiting electric push rod 14 drives the limiting shaft 15 to move, so that the limiting shaft 15 is inserted into the opening structure at the rear end of the chassis of the tractor 1, the rotation axis of the transmission frame 13 coincides with the axis of the limiting shaft 15. The connecting electric push rod 16 drives the positioning tooth 17 to move, pushing the tooth structure of the positioning tooth 17 into the interior of the positioning rod 22, thereby restricting the position of the housing 21.

[0025] A storage mechanism 2 is installed above the transmission frame 13 for storing waste. The storage mechanism 2 includes a box 21 fitted and installed above the transmission frame 13. A positioning rod 22 is provided at the bottom of the box 21. Connecting frames 23 are fixedly installed on both sides of the front end of the box 21. A supporting electric push rod 24 is fixedly installed below the connecting frame 23. The length of the box 21 is greater than the chassis of the tractor 1. The front end of the positioning rod 22 is tapered, and the width of the positioning rod 22 matches the left and right spacing of the protruding structure above the transmission frame 13. Openings that engage with the toothed structure of the positioning teeth 17 are provided on both sides of the positioning rod 22.

[0026] Specifically, the container 21 can store garbage, the tapered structure at the front end of the positioning rod 22 facilitates the docking of the container 21 with the transmission frame 13, the connecting frame 23 can limit the position of the supporting electric push rod 24, the front supporting electric push rod 24 can support the container 21 after it is removed, and the rear supporting electric push rod 24 can prevent the container 21 from moving during the garbage dumping process.

[0027] A support mechanism 3 is installed on the rear side of the tractor 1. The support mechanism 3 includes a limiting base 31 fixedly installed on the rear side of the bottom of the box 21. A bearing 32 is fitted inside the limiting base 31. A transition column 33 is inserted inside the bearing 32. A spring 34 is fixedly installed at the bottom of the transition column 33. A transition block 35 is fixedly installed at the bottom of the spring 34. A support wheel 36 is movably installed inside the transition block 35. The upper inner wall of the limiting base 31 has protruding structures on both sides. The transition column 33 is rotatably connected to the limiting base 31 through the bearing 32. The upper front and rear sides of the transition column 33 have protruding structures. The protruding structures of the transition column 33 are located between the protruding structures on both sides of the upper top of the limiting base 31. The spring 34 is symmetrically installed at the bottom of the transition column 33. The central shaft of the support wheel 36 meshes with the transition block 35.

[0028] Specifically, the limiting base 31 can limit the rotation angle of the adapter column 33, the bearing 32 can facilitate the rotation of the adapter column 33, the adapter column 33 can make the support wheel 36 rotate a certain angle based on its own center of gravity, so that when turning, the support wheel 36 can generate an angle opposite to that of the front wheel of the tractor 1 to reduce the turning radius, the spring 34 can play a shock absorption role, the adapter block 35 can facilitate the connection between the support wheel 36 and the adapter column 33, and the support wheel 36 can support the rear end of the box 21. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0029] During operation, when the limiting electric push rod 14 drives the limiting shaft 15 to move, causing the limiting shaft 15 to insert into the opening structure at the rear end of the chassis of the tractor 1, the rotation axis of the transmission frame 13 coincides with the axis of the limiting shaft 15. Furthermore, the connecting electric push rod 16 pushes the toothed structure of the positioning tooth 17 into the positioning rod 22, restricting the position between the container 21 and the transmission frame 13. This restricts the position of the container 21 during transportation. When dumping garbage, the supporting electric push rod 24 at the rear end of the container 21 supports the rear end of the container 21, causing the support wheel 36 to lift off the ground. The limiting electric push rod 14 then retracts to unlock the transmission frame 13. The lifting piston 12 then drives the transmission frame 13 and the container 21 to rotate around the contact point between the bottom end of the supporting electric push rod 24 at the rear end of the container 21 and the ground to dump the garbage. This method... While restricting the position of the container 21 during transportation, it reduces the operation of moving the transmission frame 13 via the electric push rod, thereby saving the time required for dumping garbage. The upper inner wall of the limiting base 31 is provided with protruding structures on both sides. The adapter column 33 is rotatably connected to the limiting base 31 through the bearing 32. The upper front and rear sides of the top of the adapter column 33 are provided with protruding structures. The protruding structures of the adapter column 33 are located between the protruding structures on both sides of the top of the limiting base 31. The limiting base 31 can limit the rotation angle of the adapter column 33 so that when turning, the support wheel 36 can generate an angle opposite to that of the front wheel of the tractor 1 to reduce the turning radius. In addition, the support wheel 36 can support the rear end of the container 21, share the weight of the garbage borne by the tractor 1, and reduce the turning radius to increase the single load capacity.
