Description

Technical Field

[0001] This utility model relates to the field of waste treatment equipment technology, and in particular, to a waste compression device. Background Technology

[0002] Waste compression equipment is one of the main pieces of equipment for compressing and reducing the volume of waste. It mainly uses a hydraulic system to compress the collected waste to reduce its volume. Waste compression equipment is a key piece of equipment in waste transfer stations.

[0003] Waste compression equipment mainly uses physical compression. Through the action of external pressure, the gaps between various substances in the waste are reduced, thereby reducing the space in which various substances exist in the waste and increasing the waste density.

[0004] Existing waste compression equipment typically includes a collection box and hydraulic cylinders. During operation, waste is fed into the collection box, and then the hydraulic cylinders are activated to compress the waste. To improve compression quality, manufacturers generally use a sequential feeding and compression method. That is, a portion of waste is first fed into the collection box, then compressed once, then another portion is fed in, and compressed again, and so on, until the collection box is full. This compression method requires the pressure plate to extend to the bottom of the collection box during the initial compression stage. This necessitates a relatively long extension shaft design for the hydraulic cylinder, which can lead to various problems. For example, an excessively long extension shaft can cause stress to concentrate at both ends of the shaft, increasing the risk of bending and deformation. Long-term use may lead to fatigue damage or even breakage of the shaft, resulting in poor operational reliability. Another example is that an excessively long extension shaft requires a sufficiently large stroke, increasing the length of the hydraulic cylinder, which makes installation more difficult in production sites with limited space. Furthermore, long-stroke hydraulic cylinders have relatively poor response speeds, making it impossible to achieve rapid operation and slowing down the waste compression process. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned defects in the prior art, a waste compression device with good working reliability, easy installation and fast response speed is provided.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a garbage compression device, including a base, a collection box, a support plate, a lifting drive mechanism, and a compression mechanism. The collection box is connected at both ends and is disposed on the base. The lifting drive mechanism drives the support plate to move longitudinally within the collection box. The compression mechanism includes a pressure plate for compressing garbage and a hydraulic cylinder for driving the pressure plate to move. The lifting drive mechanism includes two intersecting and hinged connecting rods, an upper slider hinged to the upper end of the connecting rods, and a lower slider hinged to the lower end of the connecting rods. The upper slider is slidably engaged with the lower surface of the support plate, and the lower slider is slidably disposed on the upper surface of the base. The lifting drive mechanism also includes a drive structure for driving the lower slider to move in the horizontal direction.

[0007] Furthermore, the collection box has a first box wall and a second box wall opposite to each other, and both the first box wall and the second box wall are provided with discharge ports. The two discharge ports are arranged opposite to each other. A baffle for blocking the discharge ports is installed on the collection box. A feeding port is provided on the side wall of the collection box, and the feeding port is located above one of the discharge ports.

[0008] Furthermore, the baffle is fixedly connected to the central box by bolts, or the baffle is hinged to the central box, or the baffle is slidably connected to the central box.

[0009] Furthermore, a groove is provided on the lower surface of the support plate, and the upper slider is slidably engaged in the groove.

[0010] Furthermore, the groove is a T-shaped groove, and the upper slider is a T-shaped block that cooperates with the T-shaped groove.

[0011] Furthermore, a guide groove is provided on the upper surface of the base, and the lower slider is slidably disposed in the guide groove. The driving structure can drive the lower slider to slide along the length direction of the guide groove.

[0012] Furthermore, the drive structure includes a drive motor mounted on the base and a lead screw connected to the output shaft of the drive motor. The lead screw extends into the guide groove and has two threaded segments with opposite directions of thread. The two threaded segments are respectively threadedly connected to the two lower sliders.

[0013] The beneficial effects of this utility model are as follows: The garbage compression equipment of this utility model adopts a method of sequential feeding and sequential compression to compress garbage, which improves the garbage compression quality. During the operation, the support plate used to support the garbage is lifted, so that the extension shaft of the hydraulic cylinder does not need to drive the pressure plate to the bottom of the collection box to realize the garbage compression operation. When designing the hydraulic cylinder, it is not necessary to design the extension shaft on the hydraulic cylinder used to connect the pressure plate to be too long, which effectively prevents breakage, ensures the response speed of the hydraulic cylinder, and does not affect the installation of the hydraulic cylinder due to excessive stroke.

[0019] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] Please see Figures 1-3 This utility model provides a waste compression device, including a base 1, a collection box 2, a support plate 3, a lifting drive mechanism 4, and a compression mechanism 5. The collection box 2 is fixedly installed on the upper surface of the base 1. The support plate 3 is installed inside the collection box 2 and can move longitudinally. The lifting drive mechanism 4 is located below the support plate 3 and is used to drive the support plate 3 to move. The compression mechanism 5 is located above the support plate 3. During operation, the waste to be compressed is put into the support plate 3 inside the collection box 2, and then the compression mechanism 5 compresses the waste put into the collection box 2.

[0021] To facilitate the feeding of garbage into the centralized container 2, a feeding port 201 is provided on the side wall of the centralized container 2. In specific implementation, a belt conveyor mechanism can be set on the side of the centralized container 2 located at the feeding port 201. The garbage to be compressed is conveyed to the feeding port 201 by the belt and put into the centralized container 2.

[0022] The collection box 2 is a hollow cuboid structure with both ends open. The support plate 3 is a flat plate structure, horizontally positioned inside the collection box 2 and cooperating with it. The collection box 2 has a first box wall 21 and a second box wall 22, each with a discharge port 202. The two discharge ports 202 are positioned opposite each other, and the feeding port 201 is located above one of the discharge ports 202. A baffle 23 is installed on the collection box 2 to block the discharge ports 202. During normal garbage compression, the baffle 23 closes the discharge ports 202. After compression, the user removes the baffle 23, which opens the discharge ports 202 on both sides. At this time, the user can drive the push plate horizontally through the cylinder to push the compacted garbage block to the outside of the collection box 2 through the discharge ports 202. In this embodiment, the baffle 23 is fixedly connected to the collection box 2 by bolts. In other embodiments, the baffle 23 can also be installed on the collection box 2 by means of hinge or sliding connection. In this case, the user can flip the baffle 23 outward or slide the baffle 23 to one side to open the discharge port 202. This is not limited here.

[0023] The lifting drive mechanism 4 includes two intersecting and hinged connecting rods 41, an upper slider 42 hinged to the upper end of the connecting rods 41, and a lower slider 43 hinged to the lower end of the connecting rods 41. The connecting rods 41, upper slider 42, and lower slider 43 are all located within the space below the support plate 3 within the central box 2. There are two upper sliders 42, one hinged to the upper end of one connecting rod 41, and the upper slider 42 is slidably engaged with the lower surface of the support plate 3. There are also two lower sliders 43, one hinged to the lower end of one connecting rod 41, and the lower slider 43 is slidably disposed on the upper surface of the base 1. Furthermore, the lifting drive mechanism 4 also includes a drive structure for driving the lower slider 43 to move horizontally.

[0024] During operation, the drive structure drives the two lower sliders 43 to move synchronously in directions away from or close to each other, thereby driving the two connecting rods 41 to rotate around the hinge center, which in turn causes the upper slider 42 to slide relative to the support plate 3. During the above process, under the drive of the connecting rods 41, the support plate 3 will move downward or upward in the longitudinal direction, thereby moving the support plate 3 away from or close to the compression mechanism 5.

[0025] At the start of operation, the drive structure drives the support plate 3 upward, placing it in a high position. At this point, the support plate 3 is close to the compression mechanism 5. Then, some waste is fed onto the support plate 3 of the collection box 2 through the feeding port 201. The compression mechanism 5 then performs a downward compression. Next, the support plate 3 is moved downward a certain distance to free up the space occupied by the compacted waste below the compression mechanism 5, and the compression mechanism 5 is reset. This allows waste to be fed into the collection box 2 through the feeding port 201, and then some more waste is fed onto the support plate 3. The compression mechanism 5 then performs a second downward compression, and this cycle repeats, with the support plate 3 descending and the compression mechanism 5 compressing successively, ultimately completing one cycle of compression.

[0026] In this embodiment, the compression mechanism 5 includes a pressure plate 51 for compressing waste and a hydraulic cylinder 52 for driving the pressure plate 51 to move longitudinally upward or downward. Specifically, a fixed bracket (not shown in the figure) is fixedly connected to the base 1, and the cylinder body of the hydraulic cylinder 52 is fixedly mounted on the fixed bracket. Therefore, during the aforementioned use, the pressure plate 51 will not extend into the bottom space of the collection box 2. Thus, when designing the hydraulic cylinder 52, it is not necessary to design the protruding shaft of the hydraulic cylinder 52 for connecting the pressure plate 51 to be too long, thereby preventing breakage, ensuring the response speed of the hydraulic cylinder, and at the same time, not affecting the installation of the hydraulic cylinder 52 due to excessive stroke.

[0027] In this embodiment, a groove 31 is provided on the lower surface of the support plate 3, and the upper slider 42 is slidably engaged in the groove 31. The slidable engagement means that the upper slider 42 can slide along the groove 31 but cannot disengage from the groove 31. Specifically, the groove 31 is a T-shaped groove, and the upper slider 42 is a T-shaped block that cooperates with the T-shaped groove.

[0028] In addition, a guide groove 11 is provided on the upper surface of the base 1, and the lower slider 43 is slidably disposed in the guide groove 11. During operation, the lower slider 43 slides along the length direction of the guide groove 11 under the drive of the drive structure. In this embodiment, the drive structure is a screw transmission mechanism, which includes a drive motor 44 mounted on the base 1 and a screw 45 connected to the output shaft of the drive motor 44. The screw 45 extends into the guide groove 11 and has two threaded sections with opposite directions of thread. The two threaded sections are respectively threadedly connected to the two lower sliders 43. Therefore, when the drive motor 44 is started to drive the screw 45 to rotate, the two lower sliders 43 can move along the guide groove 11 in a direction away from or close to each other under the drive of the screw 45, thereby changing the angle between the two connecting rods 41 to adjust the height of the support plate 3. The threaded connection between the screw 45 and the lower slider 43 gives the screw 45 a certain self-locking function, which can effectively prevent the lower slider 43 from sliding easily and improve the reliability of operation.

[0029] The waste compression equipment of this utility model adopts a method of sequential feeding and sequential compression to compress waste, which improves the quality of waste compression. During operation, the support plate 3 used to support the waste is lifted, so that the extension shaft of the hydraulic cylinder 52 does not need to drive the pressure plate 51 to the bottom of the collection box 2 to realize the waste compression operation. When designing the hydraulic cylinder 52, it is not necessary to design the extension shaft of the hydraulic cylinder 52 used to connect the pressure plate 51 to be too long, which effectively prevents breakage, ensures the response speed of the hydraulic cylinder, and does not affect the installation of the hydraulic cylinder 52 due to excessive stroke.

[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
