Description

Technical Field

[0001] This utility model relates to the field of garbage collection and transportation technology, and in particular to a loading and unloading device for a compressed garbage collection vehicle. Background Technology

[0002] As a key component of compressed garbage trucks, the loading and unloading device directly affects the overall effect of garbage collection and transportation due to its operating efficiency, sealing performance, and ease of operation.

[0003] The existing loading and unloading device includes components for compressing garbage and components for pushing and unloading the fully loaded garbage after compression. The drive structure of these two components and the protective structure for protecting the drive structure to reduce the impact of garbage on the drive structure are not well optimized. They occupy too much of the internal space of the garbage bin, and the protective structure is difficult to clean after it becomes blocked. Utility Model Content

[0004] In view of this, the present invention provides a loading and unloading device for a compressed garbage truck to solve the problem that the protective structure is difficult to clear after it becomes blocked.

[0005] The technical solution proposed by this utility model is as follows: a loading and unloading device for a compressed garbage truck, specifically including a garbage bin, the garbage bin having a structure with a sealed front end and an open rear end, and a compression plate and a discharge plate slidably installed inside the garbage bin; two U-shaped protective tubes are symmetrically welded to the inner sides of the two long side walls of the garbage bin, and U-shaped grooves are opened through both sides of the compression plate and the discharge plate, with a slider and a U-shaped slider integrally formed inside the U-shaped groove, the U-shaped groove slidingly engaging with the U-shaped protective tube; a long strip groove is opened through the bottom wall of the U-shaped protective tube, the slider slidingly engaging with the long strip groove, the U-shaped slider slidingly engaging with the internal space of the U-shaped protective tube, and a threaded drive shaft and a threaded propulsion shaft are rotatably installed at intervals inside the U-shaped protective tube, the threaded drive shaft and the threaded propulsion shaft engaging with the slider through threads, for respectively propelling and driving the compression plate and the discharge plate; detachable U-shaped end caps are installed on the openings at both ends of the U-shaped protective tube, and the ends of the threaded drive shaft and the threaded propulsion shaft are rotatably engaged with the U-shaped end caps.

[0006] Furthermore, in the initial state, the unloading plate is in contact with the front end blocking plate of the garbage bin, and the compression plate is positioned near the rear end opening of the garbage bin.

[0007] Furthermore, the U-shaped slider is provided with closely spaced threaded holes and through holes, and the threaded holes and through holes of the sliders on the compression plate and the unloading plate are arranged alternately and inverted.

[0008] Furthermore, the threaded hole of the U-shaped slider on the compression plate is screwed into the thread of the threaded propulsion shaft, and the threaded hole of the U-shaped slider on the unloading plate is screwed into the thread of the threaded drive shaft.

[0009] Furthermore, a gap is maintained between the through hole and both the threaded feed shaft and the threaded drive shaft.

[0010] Furthermore, two drive assemblies are fixedly installed symmetrically on the outer side of the front end of the garbage bin. The upper drive assembly is driven by two threaded drive shafts through a drive chain arranged in a triangle, and the lower drive assembly is driven by two threaded drive shafts through a transmission chain arranged in a triangle.

[0011] Furthermore, a feed chute is welded to the top of the trash can, and an openable and closable cover is installed on the feed inlet of the feed chute. An electrical control box is fixedly installed on the outer side of one long side wall of the garbage bin, and an electrical control unit for controlling the start and stop of the drive assembly is installed inside the electrical control box.

[0012] The present invention provides a loading and unloading device for a compressed garbage truck, which has the following beneficial effects: 1. The threaded drive shaft and threaded propulsion shaft, serving as the propulsion drive components for the compression plate and unloading plate, are concealed within the U-shaped protective tube. The U-shaped protective tube effectively blocks and shields the garbage in the bin, significantly reducing the likelihood of the garbage coming into contact with the threaded drive shaft and threaded propulsion shaft, causing them to be squeezed and jammed. This helps ensure their long-term effective rotational operation. The threaded drive shaft and threaded propulsion shaft are integrated inside the U-shaped protective tube, which is slender in diameter and has a small overall volume. This allows the threaded drive shaft, threaded propulsion shaft, and U-shaped protective tube to be assembled with a high degree of integration. The overall size of the three components is small, reducing the space occupied inside the garbage bin and indirectly expanding the effective capacity of the garbage bin.

[0013] Second, the U-shaped end cap is detachable. By removing the U-shaped end cap, the openings at both ends of the U-shaped protective tube can be opened. The U-shaped slider can be used to slide back and forth inside the U-shaped protective tube to push out the debris blocking the U-shaped protective tube through the openings at both ends, thus clearing the blockage. This eliminates the trouble of manually using hand tools to remove the blockage inside the U-shaped protective tube, and helps to improve the convenience of cleaning the U-shaped protective tube.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please refer to Figures 1 to 7 Example 1: This embodiment proposes a loading and unloading device for a compressed garbage truck, including a garbage bin 1. The garbage bin 1 has a structure with a sealed front end and an open rear end. A compression plate 2 and a discharge plate 3, adapted to the shape of the compression plate 2 and discharge plate 3, are slidably installed inside the garbage bin 1. Two U-shaped protective tubes 4 are symmetrically welded to the inner sides of the two long side walls of the garbage bin 1. A U-shaped groove 11 is opened through the middle of both sides of the compression plate 2 and discharge plate 3. A slider 10 and a U-shaped slider 9 are integrally formed inside the U-shaped groove 11. The U-shaped groove 11 slides in cooperation with the U-shaped protective tube 4. A long strip groove is opened through the bottom wall of the U-shaped protective tube 4. 404, the slider 10 slides through the long slide groove 404, the U-shaped slider 9 slides through the internal space of the U-shaped protective tube 4, and the threaded drive shaft 402 and threaded propulsion shaft 403 are rotatably installed inside the U-shaped protective tube 4. The threaded drive shaft 402 and threaded propulsion shaft 403 are threadedly engaged with the slider 10 and are used to push and drive the compression plate 2 and the unloading plate 3 respectively. The openings at both ends of the U-shaped protective tube 4 are equipped with detachable U-shaped end caps 401, and the ends of the threaded drive shaft 402 and threaded propulsion shaft 403 are rotatably engaged with the U-shaped end caps 401.

[0020] Preferably, in the initial state, the unloading plate 3 abuts against the first end blocking plate of the garbage bin 1, and the compression plate 2 is set near the tail end opening of the garbage bin 1 to cover the tail end opening.

[0021] Preferably, the U-shaped slider 9 has threaded holes 901 and through holes 902 that are closely spaced apart, and the threaded holes 901 and through holes 902 on the slider 9 of the compression plate 2 and the unloading plate 3 are arranged alternately and inverted.

[0022] Preferably, the threaded hole 901 of the U-shaped slider 9 on the compression plate 2 is screwed into the threaded push shaft 403, and the threaded hole 901 of the U-shaped slider 9 on the unloading plate 3 is screwed into the threaded drive shaft 402.

[0023] Preferably, there is a gap between the through hole 902 and the threaded push shaft 403 and the threaded drive shaft 402.

[0024] Implementation 2: This embodiment is based on Implementation 1, but with the following additions: Two drive assemblies 6 are fixedly installed symmetrically on the outer side of the front end of the garbage bin 1. The upper drive assembly 6 is driven by two threaded drive shafts 403 through a drive chain 8 arranged in a triangle, and the lower drive assembly 6 is driven by two threaded drive shafts 402 through a transmission chain 7 arranged in a triangle.

[0025] Preferably, a feed trough 101 is welded to the top of the garbage bin 1, and an openable and closable cover plate 102 is installed on the feed inlet of the feed trough 101; an electrical control box 5 is fixedly installed on the outer side of a long side wall of the garbage bin 1, and an electrical control unit for controlling the start and stop of the drive assembly 6 is provided inside the electrical control box 5.

[0026] The following provides a detailed explanation of the specific details, implementation steps, functions and interrelationships of the features in the above embodiments, and the roles these features play in implementing this technical solution: Garbage bin 1 is fixedly installed on the load-bearing pallet of the garbage truck. In use, the cover 102 is opened, and garbage is fed into garbage bin 1 through the feed chute 101. Driven by the drive chain 8, the upper drive assembly 6 drives two threaded push shafts 403 to rotate synchronously forward, pushing the two U-shaped sliders 9 on the compression plate 2 and the compression plate 2 towards the unloading plate 3. This compresses the garbage placed inside garbage bin 1 and located between the compression plate 2 and the unloading plate 3, reducing its volume and indirectly expanding the holding capacity of garbage bin 1. The drive chain 7 and the lower drive assembly 6 can drive the two threaded drive shafts 402 to rotate synchronously in the forward direction, pushing the unloading plate 3 to slide towards the compression plate 2. When the compacted garbage is full, the lower drive assembly 6 drives the unloading plate 3 to slide towards the tail end of the garbage bin 1, so that the compacted garbage is pushed out through the tail end opening of the garbage bin 1. Note that during this process, the upper drive assembly 6 should also drive the compression plate 2 and the unloading plate 3 to slide in the same direction to avoid the compression plate 2 being stationary and blocking the normal pushing and unloading of the unloading plate 3.

[0027] The threaded drive shaft 402 and the threaded propulsion shaft 403, serving as the propulsion drive components for the compression plate 2 and the unloading plate 3, are concealed within the U-shaped protective tube 4. The U-shaped protective tube 4 can block and shield the garbage in the garbage bin 1, greatly reducing the chance of the garbage in the garbage bin 1 coming into contact with the threaded drive shaft 402 and the threaded propulsion shaft 403 and squeezing and jamming them, thus helping to ensure their long-term effective rotational operation. The threaded drive shaft 402 and the threaded propulsion shaft 403 are integrated inside the U-shaped protective tube 4, and the overall U-shaped protective tube 4 is slender with a small diameter and volume. This allows the threaded drive shaft 402, the threaded propulsion shaft 403, and the U-shaped protective tube 4 to be assembled with a high degree of integration. The overall volume of the three is small, which can reduce the space occupied inside the garbage bin 1 and indirectly expand the effective capacity of the garbage bin 1.

[0028] Due to the design of the elongated chute 404, during prolonged use, garbage in the garbage bin 1 may still enter the U-shaped protective tube 4 through the elongated chute 404, causing jamming of the threaded drive shaft 402 and the threaded push shaft 403. Consequently, the U-shaped protective tube 4 needs to be cleaned periodically at longer intervals. The U-shaped end cap 401 is detachable. By removing the U-shaped end cap 401, the openings at both ends of the U-shaped protective tube 4 can be opened. The reciprocating sliding of the U-shaped slider 9 inside the U-shaped protective tube 4 can push and discharge the garbage blocking the U-shaped protective tube 4 through the openings at both ends of the U-shaped protective tube 4, thus clearing and unblocking the U-shaped protective tube 4. This eliminates the trouble of manually using hand tools to remove the garbage blocking the U-shaped protective tube 4, and helps to improve the ease of cleaning the U-shaped protective tube 4.

[0029] It is worth noting that the composition of the electronic control unit, its connection and wiring method with the drive assembly 6, and its control principle for the drive assembly 6 are existing technologies for those skilled in the art engaged in equipment electrification design, and therefore will not be elaborated here.

[0030] The following points should be noted in this article: 1. The accompanying drawings of this utility model embodiment only involve the structure involved in this utility model embodiment; other structures can refer to general designs.

[0031] 2. Where there is no conflict, the embodiments of this utility model and the features in the embodiments can be combined with each other to obtain new embodiments.

[0032] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
