Description

Technical Field

[0001] This utility model relates to the field of waste treatment equipment technology, and more specifically, to a waste compression device and a garbage truck. Background Technology

[0002] Currently, waste compression devices generally include horizontal direct pressure type and scraper plate type, among which the horizontal direct pressure type is widely used due to its simple structure. After the waste enters the feeding chamber and compression chamber through the feeding hopper, the drive cylinder is activated, which drives the compression pusher to reciprocate in the compression chamber, forcing the waste into the storage chamber. Through the mutual squeezing of the waste in the storage chamber, the purpose of compression and volume reduction is ultimately achieved.

[0003] The inventors discovered that current horizontal direct-pressure garbage compactors have gaps between the bottom of the compression chamber and the pusher head, which allows small pieces of garbage and wastewater to enter the rear of the pusher head during compression, making cleaning difficult. Utility Model Content

[0004] The purpose of this utility model is to provide a garbage compression device and a garbage truck that can improve the problem that fine garbage and sewage can enter the rear of the pusher through gaps during the compression process, making cleaning difficult.

[0005] The embodiments of this utility model can be implemented as follows:

[0006] In a first aspect, this utility model provides a waste compression device, comprising:

[0007] The room includes a storage chamber, a compression chamber, and a feeding chamber, wherein the feeding port of the compression chamber is connected to the feeding port of the feeding chamber, and the feeding port of the compression chamber is connected to the feeding port of the storage chamber.

[0008] A compression pusher is configured to reciprocate within the compression chamber to push waste in the feed chamber into the storage chamber;

[0009] The compression push head includes a push head body, an upper push plate, and a lower push plate. The upper push plate is fixedly disposed on one side of the push head body, and the lower push plate is rotatably disposed on the lower end of the upper push plate.

[0010] The waste compression device has a horizontal compression state and a lifting and unloading state. In the horizontal compression state, the upper push plate and the lower push plate together form a compression surface for compressing waste, and the center of the compression surface is recessed towards the push head body. In the lifting and unloading state, the lower push plate rotates away from the push head body under the action of gravity to discharge the waste between the lower push plate and the push head body.

[0011] In an optional embodiment, the cross-section of the compression surface is one of a cone shape, a wedge shape, or an arc shape.

[0012] In an optional embodiment, a movable hinge is provided between the lower push plate and the upper push plate.

[0013] In an optional embodiment, the waste compression device further includes a limiting member disposed on the upper push plate and used to prevent the lower push plate from rotating toward the push head body in the horizontal compression state.

[0014] In an optional embodiment, the limiting member includes a limiting block disposed on the upper push plate and extending toward the lower push plate to abut against the lower push plate in the horizontal compression state and to prevent the lower push plate from rotating toward the push head body.

[0015] In an optional embodiment, the waste compression device further includes a drive unit disposed in the compression chamber and connected to the pusher body, the drive unit being used to drive the compression pusher to reciprocate within the compression chamber.

[0016] In an optional embodiment, the driving component includes driving cylinders, and two driving cylinders are arranged in a scissor-like manner in the compression chamber and connected to the pusher body.

[0017] In an optional embodiment, the driving component includes driving cylinders, and two driving cylinders are arranged in a scissor-like manner in the compression chamber and connected to the pusher body.

[0018] In an optional embodiment, the driving component further includes a pusher arm and a slider. The sliders are provided on both sides of the pusher body. The pusher arm is fixedly connected to the pusher body through the sliders. One end of the driving cylinder is connected to the side wall of the compression chamber, and the other end is connected to the pusher arm.

[0019] Secondly, this utility model provides a garbage truck, including the garbage compression device described in any of the foregoing embodiments.

[0020] In an optional embodiment, the garbage truck further includes a lifting mechanism connected to the garbage compression device and used to drive the garbage compression device to switch between the horizontal compression state and the lifting and unloading state.

[0021] The beneficial effects of the garbage compression device and garbage truck provided in this embodiment of the utility model include:

[0022] By configuring the compression pusher head as a pusher head body, an upper pusher plate, and a lower pusher plate, when the garbage compactor compresses the garbage, the upper and lower pusher plates together form a compression surface to compress the garbage. When the garbage compactor is in the lifting and unloading state, the lower pusher plate rotates under gravity, and the garbage that has entered behind the lower pusher plate is automatically discharged under gravity. This improves the problem of garbage entering the rear of the pusher head and causing cleaning difficulties in traditional garbage compactors. Attached Figure Description

[0037] Currently, garbage compression devices generally include horizontal direct pressure type and scraper plate type, among which the horizontal direct pressure type is widely used due to its simple structure. The principle of the horizontal direct pressure garbage compressor is as follows: after the garbage enters the feeding chamber and compression chamber through the feeding hopper, the drive cylinder is activated, which drives the compression pusher to reciprocate in the compression chamber, forcing the garbage into the storage chamber. Through the mutual squeezing of the garbage in the storage chamber 110, the purpose of compression and volume reduction is ultimately achieved.

[0038] However, in actual operation, due to the gap between the pusher head and the bottom of the compression chamber, small debris and sewage can enter the rear of the pusher head during the compression process, making cleaning difficult.

[0039] To address the problem that fine waste and wastewater can enter the rear of the compactor head during garbage compression, making cleaning difficult, this utility model provides a garbage compression device and a garbage truck. The overall structure, working principle, and technical effects of the garbage compression device and garbage truck provided by this utility model are described in detail below through embodiments and accompanying drawings.

[0040] Please refer to Figure 1 and Figure 2 On the one hand, this utility model provides a garbage truck for the collection, transfer, and treatment of garbage. The garbage truck provided by this utility model includes a garbage compression device 100 and a lifting mechanism 200. The garbage compression device 100 is installed in the garbage truck's cargo compartment, and the lifting mechanism 200 is installed on the garbage truck and connected to the garbage compression device 100. The lifting mechanism 200 is used to drive the garbage compression device 100 from a horizontal compression state to a lifting and unloading state. In the horizontal compression state, the garbage compression device 100 is placed horizontally on the garbage truck. In the lifting and unloading state, the end of the garbage compression device 100 near the front of the truck is lifted by the lifting mechanism 200, and the garbage in the garbage compression device 100 is discharged from the end away from the front of the truck.

[0041] Please refer to Figure 2 On the other hand, this utility model provides a garbage compression device 100, which is applied to the aforementioned garbage truck to compress garbage, thereby increasing the loading capacity of the garbage truck, reducing the frequency of transportation, and optimizing the storage and treatment of garbage.

[0042] The waste compression device 100 provided by this utility model includes a storage chamber 110, a compression chamber 120, and a feeding chamber 130. The feeding chamber 130 is located at one end of the storage chamber 110, and the compression chamber 120 is located at the bottom of the feeding chamber 130. The inlet of the compression chamber 120 is connected to the outlet of the feeding chamber 130, and the outlet of the compression chamber 120 is connected to the inlet of the storage chamber 110. The waste compression device 100 also includes a compression pusher 140, which is slidably installed in the compression chamber 120. Waste fed into the feeding chamber 130 falls into the compression chamber 120 from the lower outlet, and the compression pusher 140 pushes the waste falling into the compression chamber 120 into the storage chamber 110. As the waste is continuously pushed into the storage chamber 110, the compression pusher 140 causes the waste to squeeze against each other in the storage chamber 110, thereby fully squeezing and compressing the waste in the storage chamber 110 to achieve the purpose of compression and volume reduction.

[0043] Please refer to Figure 2 and Figure 3In this embodiment, the compression pusher 140 includes a pusher body 141, an upper pusher plate 142, and a lower pusher plate 143. The upper pusher plate 142 is mounted on one side of the pusher body 141, and the lower pusher plate 143 is rotatably mounted on the lower end of the upper pusher plate 142. The waste compression device 100 has a horizontal compression state ( Figure 2 The states shown are the same as the lifting and unloading states. Figure 1 (As shown in the diagram), in the horizontal compression state, the upper push plate 142 and the lower push plate 143 together form a compression surface. When the waste compression device 100 moves within the compression chamber 120, the compression surface contacts the waste and is used to compress it. To improve the compression effect of the compression surface on the waste, the middle part of the compression surface is recessed towards the pusher body 141. Please refer to... Figure 4 In the lifting and unloading state, one end of the feeding chamber 130 of the garbage compression device 100 is lifted by the lifting mechanism 200 on the garbage truck, and the compressed garbage in the storage chamber 110 is discharged. At this time, the lower push plate 143 rotates away from the push head body 141 under the action of gravity to discharge the garbage between the lower push plate 143 and the push head body 141.

[0044] By configuring the compression pusher 140 as a pusher body 141, an upper pusher plate 142, and a lower pusher plate 143, when the garbage compression device 100 compresses garbage, the upper pusher plate 142 and the lower pusher plate 143 together form a compression surface to compress the garbage; and when the garbage compression device 100 unloads in the lifting and unloading state, the lower pusher plate 143 rotates under gravity, and the garbage that enters behind the lower pusher plate 143 is automatically discharged under gravity. This improves the problem of garbage entering the rear of the pusher head and causing cleaning difficulties when traditional garbage compressors are working.

[0045] Please refer to Figure 2 and Figure 3 To concentrate pressure during waste compression, reduce energy loss, and prevent lateral dispersion of waste, the center of the compression surface is recessed towards the pusher body 141. In this embodiment, the cross-sectional shape of the compression surface is a concave arc shape; in other embodiments, the cross-sectional shape of the compression surface can also be a concave cone shape or a concave wedge shape. This directs the compressive force towards the center of the compression surface during waste compression, thereby guiding the waste towards the center of the compression surface and improving the compression effect.

[0046] Please refer to Figure 3To facilitate the rotatable mounting of the lower push plate 143 on the upper push plate 142, a movable hinge 144 is provided between the lower push plate 143 and the upper push plate 142 to achieve a rotatable connection between them. Furthermore, to ensure that the lower push plate 143 can only rotate away from the pusher head body 141 when the waste compression device 100 is in the lifting and unloading state, and to guarantee that the lower push plate 143 and the upper push plate 142 form a compression surface to compress the waste during horizontal compression, the waste compression device 100 also includes a limiting member 150 in this embodiment. The limiting member 150 is disposed on the upper push plate 142. During horizontal compression, when the compression pusher head 140 compresses the waste, the limiting member 150 abuts against and prevents the lower push plate 143 from rotating towards the pusher head body 141.

[0047] Please refer to Figure 3 In some optional embodiments, the limiting member 150 includes a limiting block, which is disposed on the upper push plate 142 and extends toward the lower push plate 143. When the waste compression device 100 is in a horizontal compression state, the limiting block abuts against the lower push plate 143. At this time, the compression push head 140 compresses the waste, and the lower push plate 143 is subjected to the pressure of the waste. Under the action of the limiting block, the lower push plate 143 cannot rotate toward the push head body 141, so that the compression surface always maintains structural and functional integrity during the waste compression process, ensuring the compression effect.

[0048] It is understandable that when the waste compression device 100 is in a horizontal compression state and the compression pusher 140 moves away from the storage chamber 110, the lower pusher plate 143 can rotate away from the pusher body 141 under the action of external force. For example, when there is a lot of sewage remaining in the compression chamber 120, the pressure between the lower pusher plate 143 and the pusher body 141 will increase during the movement of the compression pusher 140 away from the storage chamber 110. As a result, the lower pusher plate 143 can open under the action of sewage pressure, discharging some sewage. Thus, after a certain amount of waste and sewage accumulates behind the lower pusher plate 143, some waste and sewage can be discharged without the waste compression device 100 switching to the lifting and unloading state, so as to avoid excessive waste or sewage clogging behind the lower pusher plate 143 and affecting the normal operation of the compression pusher 140.

[0049] Please refer to Figure 5 and Figure 6 The garbage compression device 100 also includes a drive unit 160, which is disposed in the compression chamber 120 and connected to the pusher body 141. The drive unit 160 is used to drive the compression pusher 140 to reciprocate within the compression chamber 120 to push the garbage falling from the feed chamber 130 into the compression chamber 120 for compression.

[0050] In some alternative embodiments, the drive unit 160 includes two drive cylinders 161, which are mounted in a scissor-like configuration within the compression chamber 120. The output ends of both drive cylinders 161 are connected to the pusher body 141. By simultaneously driving the two drive cylinders 161 to extend or retract, the two drive cylinders 161 jointly drive the compression pusher 140 to reciprocate within the compression chamber 120, thereby achieving the movement and compression of waste.

[0051] In some alternative embodiments, the drive component 160 includes drive cylinders 161. Two drive cylinders 161 are arranged parallel to each other on the side walls of the compression chamber 120. Both drive cylinders 161 are connected to the pusher body 141 to jointly drive the pusher body 141 to move. Further, the drive component 160 also includes pusher arms 162 and sliders. Pusher arms 162 are fixedly connected to both sides of the pusher body 141, and sliders are also fixedly connected to both sides of the pusher body 141. The sliders are fixedly connected to the pusher arms 162, thereby improving the connection stability between the pusher arms 162 and the pusher body 141. The drive cylinders 161 are installed along the length of the compression chamber 120 on the side walls of the compression chamber 120, and the output end of the drive cylinders 161 is connected to the pusher arms 162. By extending or retracting the drive cylinders 161, the compression pusher 140 is driven to move. When the drive cylinders 161 are arranged in a scissor configuration, the force on the compression pusher 140 is the resultant force of the output components of the two cross-arranged drive cylinders 161, which leads to a reduction in the compression capacity of the waste. However, by arranging the two drive cylinders 161 in parallel, the force on the compression pusher 140 is the sum of the output forces of the two drive cylinders 161, thereby increasing the compression force.

[0052] In summary, the implementation principle of the garbage compression device 100 and garbage truck provided by this utility model is as follows: by configuring the compression pusher 140 as a pusher body 141, an upper pusher plate 142, and a lower pusher plate 143, when the garbage compression device 100 compresses the garbage, the upper pusher plate 142 and the lower pusher plate 143 together form a compression surface to compress the garbage; and when the garbage compression device 100 unloads in the lifting and unloading state, the lower pusher plate 143 rotates under the action of gravity, and the garbage that enters behind the lower pusher plate 143 is automatically discharged under the action of gravity. This improves the problem that garbage enters the rear of the pusher head and causes cleaning difficulties when traditional garbage compressors are working.

[0053] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes 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.
