Description

Technical Field

[0001] The utility model specifically relates to a compression garbage truck, belonging to the technical field of vehicles specially applicable to garbage collection (B65F3 / 00). Background Art

[0002] The compression garbage truck is composed of a chassis, a garbage bin, a loader, a scraper and a slide plate inside the loader, a bucket lifting mechanism, a hydraulic system and a control system. When collecting and transporting garbage, the combined movement of the scraper and the slide plate inside the loader forms a compression force on the garbage and presses the garbage into the garbage bin. When unloading, the loader is lifted for unloading. To prevent sewage leakage at the joint between the loader and the garbage bin, existing garbage trucks generally are provided with a sewage tank for accommodating sewage seeping out of the garbage during driving. The garbage truck provided with a sewage tank generally needs to be provided with a large number of sealing strips at the joint between the sewage tank and the garbage bin for sealing, but there are still problems of water seepage and dripping. A solution is disclosed in the Chinese utility model patent application with the application number 202320523232.X, which adopts an integrated box structure and a flat bottom plate, reducing the sealing range of the box body, thereby reducing the risk of sewage leakage. However, the above solution changes the bottom plate of the garbage bin from a tail part with a concave section to a flat plate, resulting in a gap between the scraper inside the loader and the bottom plate when the scraper rotates, weakening the loading capacity of the loader. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is: how to improve the loading capacity of the loader in the garbage truck with a garbage bin having a flat bottom plate.

[0004] To solve the above technical problem, the technical solution proposed by the utility model is: a compression garbage truck, including a chassis and a garbage bin arranged on the chassis. One end of the garbage bin close to the head of the garbage truck is the head end, and one end close to the tail of the garbage truck is the tail end. The bottom surface of the garbage bin is flat, and the tail end of the garbage bin is inclined and open; a bucket lifting mechanism is installed at the bottom of the garbage bin near the tail end; a push plate mechanism for pushing the compressed garbage out of the garbage bin for unloading is arranged inside the garbage bin; a loader is hinged to the top of the garbage bin. The loader includes a frame structure. One end of the frame structure is hinged to the top of the garbage bin, and the other end extends obliquely into the garbage bin; a compression mechanism for loading and compressing garbage is arranged on the frame structure. The frame structure includes a frame main body, and a silo and a tail plate are connected to the frame main body; the silo is composed of a straight plate, an arc plate and side plates on both sides; a sealing ring is arranged on the tail plate;

[0005] When the garbage bin needs to be sealed and closed, the tail plate is perpendicular to the bottom surface of the garbage bin, and the sealing ring is attached to the tail of the garbage bin;

[0006] When the dustbin does not need to be sealed and closed, the loader is lifted to drive the sealing ring on the tail plate to separate from the tail of the dustbin.

[0007] Furthermore, a first guide rail parallel to the bottom surface of the dustbin is arranged inside the dustbin, and the push plate mechanism moves on the first guide rail.

[0008] Furthermore, the compression mechanism includes a slide plate oil cylinder, a slide plate, a scraper oil cylinder and a scraper; the scraper is hinged to the slide plate.

[0009] Furthermore, the frame structure further includes a second guide rail, and the slide plate oil cylinder drives the slide plate to drive the scraper to reciprocate on the second guide rail; the scraper oil cylinder drives the scraper to rotate.

[0010] Furthermore, a locking mechanism is arranged at the bottom of the dustbin near the tail end, and the locking mechanism locks the tail plate when the sealing ring on the tail plate is in contact with the tail of the dustbin.

[0011] Furthermore, a pneumatic door is arranged at the rear end of the loader to cover the loader.

[0012] Furthermore, an adjusting device is arranged at the connection between the loader and the dustbin to adjust the connection position between the loader and the dustbin.

[0013] Advantages of the present invention: 1. The bottom plate of the dustbin is a planar structure, and the push plate can directly push out the tail of the dustbin, and the garbage and sewage can be directly unloaded cleanly; 2. The loader is provided with a bin formed by an arc plate, a straight plate and two side plates on both sides. This bin forms a garbage compression space, which is higher than the bottom plate of the dustbin and can provide the same compression force as a compression truck. 3. A tail plate is arranged at the rear of the loader. When the loader is not lifted, the tail plate presses the sealing ring to fit with the tail of the dustbin to form the seal of the dustbin; it replaces the form of using a tail door seal in a conventional garbage truck, and uses the self-gravity of the loader and the locking hook to jointly achieve the seal, simplifying the mechanical mechanism.

[0022] Embodiment

[0023] As Figures 1 to 5 shown, the compression garbage truck in this embodiment includes a chassis 1 and a garbage bin 2 provided on the chassis 1. One end of the garbage bin 2 close to the front of the garbage truck is the head end, and one end close to the rear of the garbage truck is the tail end. The bottom surface of the garbage bin 2 is a plane, and the tail end of the garbage bin 2 is inclined and open; a bucket lifting mechanism 4 is installed near the tail end at the bottom of the garbage bin 2.

[0024] A first guide rail 21 parallel to the bottom surface of the garbage bin 2 is provided inside the garbage bin 2. A push plate mechanism 5 for pushing the compressed garbage out of the garbage bin for unloading is also provided inside the garbage bin 2, and the push plate mechanism 5 moves on the first guide rail 21.

[0025] A loader 3 is hinged to the top of the garbage bin 2, and a pneumatic door 6 is provided at the rear end of the loader 3 to cover the loader 3. The loader 3 includes a frame structure 34. One end of the frame structure 34 is hinged to the top of the garbage bin 2, and the other end extends obliquely into the garbage bin 2; the frame structure 34 includes a frame main body 342 and a second guide rail 341; a compression mechanism 32 for loading and compressing garbage is provided on the frame structure 34. The compression mechanism 32 includes a slide plate oil cylinder 321, a slide plate 322, a scraper oil cylinder 323 and a scraper 324; the scraper 324 is hinged to the slide plate 322; the slide plate oil cylinder 321 drives the slide plate 322 to drive the scraper 324 to reciprocate on the second guide rail 341; the scraper oil cylinder 323 drives the scraper 324 to rotate.

[0026] A silo 31 and a tail plate 33 are connected to the frame main body 342; the silo 31 is composed of a straight plate, an arc plate and side plates on both sides; a sealing ring 35 is provided on the tail plate 33;

[0027] At the bottom of the garbage bin 2 near the tail end, a locking mechanism 23 is also provided. The locking mechanism 23 locks the tail plate 33 when the sealing ring 35 on the tail plate 33 fits against the bottom surface and both side surfaces of the tail of the garbage bin 2. An adjusting device 7 is provided at the connection between the loader 3 and the garbage bin 2 for adjusting the connection position between the loader 3 and the garbage bin 2.

[0028] When the garbage bin 2 needs to be sealed and closed, the tail plate 33 is perpendicular to the bottom surface of the garbage bin 2, and the sealing ring 35 fits against the bottom surface and both side surfaces of the tail of the garbage bin 2;

[0029] When the garbage bin 2 does not need to be sealed and closed, the loader 3 is lifted, driving the sealing ring 35 on the tail plate 33 to separate from the bottom surface and both side surfaces of the tail of the garbage bin 2.

[0030] The working process of the compression garbage truck in this embodiment is as Figures 6 to 7 shown. When the garbage truck needs to be loaded, the pneumatic door 6 performs an action to open, and the bucket lifting mechanism 4 performs an action to load the garbage in the trash can into the bin 31 in the loader 3. When the garbage in the bin 31 reaches a certain amount, the loader 3 performs a loading and compressing action. Among them, the scraper oil cylinder 323 performs an action, and the end of the scraper 324 rotates clockwise along the arc plate section of the bin 31. The slide plate oil cylinder 321 performs an action, and the slide plate 322 is lifted along the slide plate guide rail 341. The end of the scraper 324 moves linearly along the straight plate section of the bin 31 to press the garbage into the garbage bin 2. This part of the garbage is then compressed by the relative extrusion of the push plate mechanism 5 at the same time. During the garbage compression process, as the amount of compressed garbage increases, the push plate mechanism 5 gradually moves backward to the front end position of the garbage bin 2 under the action of the compressed garbage and the loader 3 and stops when it can no longer move backward, completing the loading and compressing work of the garbage.

[0031] When the garbage truck needs to unload, the loader 3 starts to lift, and the push plate mechanism 5 performs an action to push the compressed garbage and sewage out from the rear end of the garbage bin 2. The loader 3 starts to fall back to the original position, and the locking mechanism 23 locks the loader 3 to achieve sealing. Thus, a collection and transfer of garbage is completed.
