Description

Technical Field

[0001] The utility model relates to the technical field of garbage recycling and processing, in particular to a garbage compression device used for an electric classified garbage truck. Background Art

[0002] Garbage trucks, also known as sanitation trucks or waste collection trucks, are special vehicles used to collect, transport and dump urban domestic garbage and other waste. Garbage trucks play an important role in modern urban sanitation systems and help keep the urban environment clean and sanitary. Among them, compression garbage trucks are equipped with hydraulic compression devices that can compress garbage, thereby increasing the amount of garbage transported in a single trip and reducing the number of trips.

[0003] For some current compression garbage trucks, the power mechanisms such as air cylinders and hydraulic cylinders required for compression are mostly installed on the car body near the front of the car. In order to ensure that the output rod has sufficient range of movement, the cylinder body itself also needs to have a certain length, which will take up a lot of installation space in the car body, thereby compressing the actual space in the car body and suppressing the garbage holding capacity of the car body. Utility Model Content

[0004] The purpose of the utility model is to provide a garbage compression device for an electric garbage classification truck to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. After the garbage is collected into the garbage truck, the lower pressure plate is lowered to compress the garbage in the garbage truck in the up and down directions. After the compression is completed, the drive motor is started to use the bevel gear set to rotate the bidirectional screw, and the drive slider is rubbed to move synchronously in the drive slide, driving the two sets of cross pressure plates to clamp the lower surface of the lower pressure plate in the front and back directions to achieve garbage compression in the front and back directions.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 6 In an embodiment of the utility model, a garbage compression device for an electric sorting garbage truck includes a garbage compartment 1, a compression structure 2 is movably installed inside the garbage compartment 1, a guide structure 3 is slidably installed at the bottom of the garbage compartment 1, the compression structure 2 includes a lower pressure plate 201, a driving motor 202 is fixedly installed in the middle of the upper surface of the lower pressure plate 201, a bidirectional screw rod 203 is buried in the middle of the lower pressure plate 201 for rotation in the front and rear directions, the output end of the driving motor 202 and the middle of the bidirectional screw rod 203 are meshed with each other through bevel gears, the threaded sections at both ends of the bidirectional screw rod 203 are rotatably installed in a driving slide groove 204, a driving slider 205 that is screwed with the bidirectional screw rod 203 is slidably installed inside the driving slide groove 204, and the driving slider 205 is fixedly installed in the middle of the upper surface of the horizontal pressure plate 206.

[0026] Specifically, after the garbage is collected into the garbage compartment 1, the lower pressure plate 201 is lowered to compress the garbage in the garbage compartment 1 in the up and down directions. After the compression is completed, the drive motor 202 is started to use the bevel gear group to rotate the bidirectional screw 203, and the drive slider 205 is rubbed to move synchronously in the drive slide groove 204, driving the two sets of horizontal pressure plates 206 to clamp in the front and back directions of the lower surface of the lower pressure plate 201, thereby realizing the compression of the garbage in the front and back directions. A secondary compression structure is added to the lower pressure plate 201 used for the main compression work, which improves the compression effect while reducing the space occupied by the compression structure in the garbage compartment 1 to maintain sufficient garbage storage space. Embodiment 1

[0027] like Figure 1-3 As shown, in this embodiment, a multi-stage hydraulic push rod 104 is fixedly installed at the four corners of the top of the garbage bin 102, and a motor storage groove 105 is opened in the middle of the upper surface of the garbage bin 102; the four corners of the upper surface of the lower pressure plate 201 are fixedly connected to the output end of the multi-stage hydraulic push rod 104.

[0028] In this embodiment, a multi-stage hydraulic push rod 104 is used to provide downward pressure to the lower pressure plate 201, and the pressure structure is set above the box body 101 to avoid occupying the garbage compartment 1 placement space on the vehicle. At the same time, a multi-stage hydraulic push rod 104 that can be folded multiple times is used to provide pressure, limiting the external height of the multi-stage hydraulic push rod 104, thereby compressing the actual height of the box body 101, avoiding some roads with height restrictions that prevent garbage trucks from passing.

[0029] like Figure 1-2 As shown, in this embodiment, the garbage truck compartment 1 includes a box body 101 , a garbage bin 102 is provided inside the box body 101 , and an entrance 103 is provided at the front side of the garbage bin 102 .

[0030] In specific implementation, when in use, the box body 101 is loaded on a garbage truck, and a garbage bin lifting structure is loaded at the inlet and outlet 103 to assist the garbage to enter the garbage bin 102 . Embodiment 2

[0031] On the basis of Example 1, in order to compensate for the fact that the driving groove 204 mentioned in Example 1 is in a through-structure in the up and down directions, when actually pressing down, the garbage will enter the driving groove 204, affecting the compression effect, and after the garbage enters the driving groove 204, it will hinder the rotation of the bidirectional screw rod 203 and the sliding of the guide slider 302.

[0032] like Figure 4-6As shown, in this embodiment, a storage sleeve 207 is fixedly connected to the middle part of the bottom side of the lower pressure plate 201, and a closed end piece 208 is fixedly connected to the middle part of the inner surface of the two transverse pressure plates 206. A multi-stage folding sleeve 209 is slidably sleeved between the two ends of the storage sleeve 207 and the two closed end pieces 208, and the multi-stage folding sleeve 209 slides against the bottom opening of the driving slide groove 204; the guide structure 3 includes a guide slide groove 301, and the guide slide groove 301 is slidably installed inside the guide slide groove 302, and a discharge port 303 is opened on the bottom side of one end of the guide slide groove 301; the guide slide groove 301 is opened on both side edges of the lower surface of the lower pressure plate 201, and the guide slide block 302 is fixedly installed on both side edges of the upper surface of the transverse pressure plate 206.

[0033] During specific implementation, when the cross pressure plate 206 moves, the multi-stage folding sleeve 209 contracts and stretches following the movement of the cross pressure plate 206, and always blocks the lower opening of the driving chute 204 to prevent garbage from entering the driving chute 204 during compression, affecting the compression effect, and hindering the rotation of the bidirectional screw rod 203; when the cross pressure plate 206 moves, the guide slider 302 slides in the guide chute 301 to assist in the restricted guiding work and ensure the smooth movement of the cross pressure plate 206. At the same time, one end of the guide slider 302 is set to an inclined wedge structure, which is convenient for the guide slider 302 to cut into the garbage stuck in the guide chute 301 when sliding, and push the garbage to the discharge port 303, and use the inclined surface to push the garbage out to prevent the garbage from being blocked in the guide chute 301.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
