[0040] Waste compactors are one of the main pieces of equipment for compressing and reducing the volume of waste, and are also a key processing device in waste transfer stations. A waste compactor is a hydraulically controlled machine that compresses collected waste to reduce its volume.

[0041] There are two main types of garbage compactors: one is an underground garbage compactor, in which the garbage container is placed in a pit, with the garbage inlet exposed on the ground, and a garbage bin or similar disposal facility is provided; the other is a ground-mounted garbage compactor, in which the garbage container is placed on the ground, with a tipping mechanism at the front of the container to transfer the garbage to the inlet at the top of the container for disposal.

[0042] In existing technologies, waste bins are either buried in pits or laid flat on the ground, making it difficult to treat the wastewater seeping out. If the waste bins are to be installed in an elevated position to facilitate wastewater treatment, the first step is to solve the problem of connecting the waste to the elevated placement.

[0043] Therefore, this utility model provides a material turning mechanism that can solve the problem of turning over waste materials from the ground to overhead placement.

[0044] Reference Figures 1 to 5 This utility model discloses a material-turning mechanism comprising a support frame 100, a swing mechanism 300, and a garbage bin 200. Specifically, the upper end of the support frame 100 is provided with an mounting position for installing the garbage bin, which can support the garbage bin in practical applications, enabling the garbage bin to be installed in an elevated position. The specific shape and size of the mounting position can be set according to the garbage bin that needs to be supported. The swing mechanism 300 is disposed between the support frame 100 and the garbage bin 200. Two swing mechanisms 300 are provided, one end of each swing mechanism 300 is connected to the upper ends of the left and right sides of the support frame 100, and the other end of each swing mechanism 300 extends downward to the front of the support frame 100 to form a mounting end. The garbage bin 200 is disposed between the mounting ends of the two swing mechanisms 300.

[0045] The swing mechanism 300 has a first state and a second state: when the swing mechanism 300 is in the first state, the mounting end is located in front of the support frame 100 and the opening of the garbage bin 200 is upward; when the swing mechanism 300 is in the second state, the mounting end is located above the mounting position and the opening of the garbage bin 200 is downward.

[0046] Understandably, when the swing mechanism 300 is in the first state, the garbage bin 200 can be used to hold garbage daily, while when it is switched to the second state, the garbage bin 200 can be controlled to flip and dump the garbage out.

[0047] Therefore, in this embodiment, the tipping mechanism uses a support frame 100 and a swing mechanism 300 to mount the garbage hopper 200. In the first state, the garbage hopper 200 is in a garbage receiving state and can be used to collect garbage. When the garbage storage reaches a set amount or after receiving garbage for a certain period of time, the swing mechanism 300 can lift the garbage hopper 200 upward and turn the opening of the garbage hopper 200 to dump the garbage out. Since the support frame 100 can be used to support the garbage container, it can realize the overhead setting of the garbage container and the docking of garbage from the ground to the overhead tipping, providing a basis for the overhead setting of the garbage container.

[0048] Reference Figure 2 In some embodiments of this utility model, the swing mechanism 300 includes a first mounting arm 301, a second mounting arm 302, a first connecting rod 303, a second connecting rod 304, and a drive unit 305. Specifically, the first end of the first mounting arm 301 is rotatably connected to the support frame 100, and the second end of the first mounting arm 301 is rotatably connected to the garbage hopper 200. The first end of the second mounting arm 302 is rotatably connected to the support frame 100, and the second end of the second mounting arm 302 is rotatably connected to the garbage hopper 200, thereby jointly controlling the lifting and tilting of the garbage hopper 200 by the rotation of the first mounting arm 301 and the second mounting arm 302. The first end of the second mounting arm 302 is located behind the first end of the first mounting arm 301, and the second end of the second mounting arm 302 is located behind the second end of the first mounting arm 301, so that the two are staggered to ensure the stability of the support for the garbage hopper 200. The first end of the first link 303 is rotatably connected to the support frame 100. Along the front-rear direction, the first end of the first link 303 is located between the first end of the first mounting arm 301 and the first end of the second mounting arm 302. The first end of the second link 304 is rotatably connected to the second end of the first link 303, and the second end of the second link 304 is rotatably connected to the first mounting arm 301. The drive unit 305 is connected to the first link 303 and is used to control the rotation of the first link 303 around its own first end.

[0049] With the structural configuration of this embodiment, when the drive unit 305 drives the first connecting rod 303 to rotate upward, the second connecting rod 304 will lift the first mounting arm 301, thereby causing the garbage bin 200 to flip upward. The garbage bin 200 will also drive the second mounting arm 302 to flip. As the flipping angle increases, the garbage bin 200 rotates relative to the first mounting arm 301 and the second mounting arm 302, gradually causing the opening to rotate from an upward angle to a downward angle, thereby realizing the switch from the first state to the second state.

[0050] With the structural configuration of this embodiment, the drive unit 305 can be a hydraulic cylinder, a pneumatic cylinder or other telescopic structure, or it can be a rotary drive structure, as long as it can drive the first connecting rod 303 to rotate around its first end.

[0051] In some embodiments of this utility model, the first mounting arm 301, the second mounting arm 302, the garbage hopper 200, and the support frame 100 form a parallelogram mechanism. This ensures the stability of the support for the garbage hopper 200 and the stability of the lifting process.

[0052] Combination Figure 2 The first mounting arm 301 includes an upper arm segment 3011 and a lower arm segment 3012. The upper arm segment 3011 and the lower arm segment 3012 are distributed at an obtuse angle, and the distance from the upper arm segment 3011 to the second mounting arm 302 is inclined away from the second mounting arm 302 relative to the axis connecting the first end and the second end of the first mounting arm 301. With the structural configuration of this embodiment, the axis connecting the first mounting arm 301 and the second mounting arm 302 form a parallelogram mechanism, but the actual structural form of the first mounting arm 301 is a bent structure away from the second mounting arm 302. This helps to control the angle between the second connecting rod 304 and the first mounting arm 301, thereby increasing the initial force on the first mounting arm 301. This reduces the difficulty of lifting the garbage bin 200 from the first state and improves the driving stability.

[0053] In some embodiments of this utility model, when the swing mechanism 300 is in the first state and the second state, the first mounting arm 301 is symmetrical about its first end by 180°. That is, when the swing mechanism 300 switches from the first state to the second state, the first mounting arm 301 rotates 180°. Figure 3 As shown, in this state, the garbage bin 200 will flip up and down under the traction of the second mounting arm 302, causing the opening to face downwards. In addition, other flipping angles can also be set, which are not limited here.

[0054] Combination Figure 2 In some embodiments of this utility model, when the swing mechanism 300 is in the first state, the first link 303 and the second link 304 form an acute angle. Furthermore, the first link 303 is a bent rod with an arc extending away from the first mounting arm 301. The drive unit 305 is connected at the midpoint of the length direction of the first link 303. When the drive unit 305 controls the first link 303 to flip upwards, the second link 304 controls the first mounting arm 301 to flip upwards, increasing the angle between the first link 303 and the second link 304. By controlling the initial angle between them to be an acute angle, transmission efficiency can be improved; a smaller opening angle between them is sufficient to drive the first mounting arm 301 to flip a larger angle.

[0055] Based on this, the drive unit 305 is configured as a hydraulic cylinder, with its lower end connected to the bottom of the support frame 100 and its upper end inclinedly connected to the first connecting rod 303. In the first state, the second connecting rod 304 is nearly parallel to the hydraulic cylinder, allowing the hydraulic cylinder to quickly transmit driving force to the second connecting rod 304, thereby pushing the first mounting arm 301 to tilt. This helps reduce the driving force requirement when the garbage bin 200 tilts, thus reducing the driving power of the hydraulic cylinder and improving the smoothness of the driving process.

[0056] Combination Figure 1 and Figure 2 In some embodiments of this utility model, the swing mechanism 300 further includes a limiting seat, which is disposed on the outside of the support frame 100 and located above the first end of the first connecting rod 303. Along the left-right direction, the limiting seat, the first mounting arm 301, the first connecting rod 303, and the second connecting rod 304 are located on the same vertical plane. The second mounting arm 302 is rotatably connected to the side of the limiting seat away from the support frame 100 and is offset from the first mounting arm 301 along the left-right direction.

[0057] It is understandable that the garbage bin 200 flips up and down when switching from the first state to the second state. The first mounting arm 301 and the second mounting arm 302 may intersect during the flipping process. In this embodiment, the first mounting arm 301 and the second mounting arm 302 are misaligned left and right by setting a limit seat, which can avoid interference during the flipping process.

[0058] In some embodiments of this utility model, when the swing mechanism 300 is in the second state, the first connecting rod 303 is close to the limiting seat. The swing mechanism 300 also includes a positioning sensor, which is disposed at the bottom of the limiting seat and is used to detect whether the first connecting rod 303 has swung to the correct position. By adopting the structural configuration of this embodiment and placing the positioning sensor below the limiting seat, the limiting seat can be prevented from being affected by dust, sewage, or overflowing garbage during the garbage dumping process, which helps to ensure the lifespan and stability of the working mechanism.

[0059] With the structural configuration of this embodiment, the limiting seat is used to maintain the non-interference movement of the first mounting arm 301 and the second mounting arm 302, and also for the installation of position detection. It has a high degree of integration, and the structure is simple and ingeniously designed.

[0060] Based on this, the first link 303 can be further stopped by the limiting seat to achieve the limiting of the first link 303's flipping.

[0061] Reference Figure 4In some embodiments of this utility model, along the front-to-back direction, the garbage bin 200 includes a first side wall 201, a bottom wall 202, and a second side wall 203 connected in sequence. The first side wall 201 is provided with a plurality of protrusions 2011, and the second side wall 203 is provided with a plurality of recesses 2031. Figure 3 As shown, in the first state, the first sidewall 201 is the front sidewall of the garbage hopper 200, while in the second state, the second sidewall 203 is the receiving wall for dumping garbage. In this embodiment, by providing a protrusion 2011 on the first sidewall 201, it helps guide the garbage towards the rear of the garbage hopper 200 when it is dumped, preventing garbage from accumulating at the front and affecting the holding capacity. By providing a recess 2031 on the second sidewall 203, the step formed by the recess 2031 can block the tendency for garbage to spill out during the process of the garbage hopper 200 flipping to the second state, preventing uncontrolled dumping and ensuring that the garbage only spills out when the garbage hopper 200 is fully flipped to the second state. In particular, it can prevent wastewater in the garbage from overflowing along the second sidewall 203 during the flipping process.

[0062] Furthermore, the structural strength of the garbage bin 200 can be effectively improved by the design of the protrusions 2011 and the recesses 2031. Figure 4 As shown, both the protrusion 2011 and the recess 2031 are structures that extend to the left and right. They can be formed by bending the plate or by welding.

[0063] In some embodiments of this utility model, drainage grooves are provided on the left and right sides of the second sidewall 203, extending from the bottom wall 202 to the upper end of the second sidewall 203. By adopting the structural configuration of this embodiment and providing drainage grooves on both sides of the second sidewall 203, the discharge speed of wastewater when the garbage hopper 200 is dumped can be improved. Combined with the recess 2031, it balances the obstruction of wastewater during the tipping process and the efficiency of wastewater discharge when tilting the garbage.

[0064] Combination Figure 1 In some embodiments of this utility model, a longitudinal beam 101 is provided on each of the left and right sides of the support frame 100 at the installation position, and multiple cross beams 102 are provided between the two longitudinal beams 101. The longitudinal beams 101 extend in the front-back direction, and the cross beams 102 extend in the left-right direction. The upper end face of the longitudinal beam 101 is provided with a mounting hole for bolts to be inserted to connect the garbage bin body. The upper end face of the cross beam 102 is provided with a positioning wedge, which is used to position the garbage bin body in the front-back direction.

[0065] Specifically, in the two staggered crossbeams 102, one crossbeam 102 has a forward-facing sloping wedge, and the other crossbeam 102 has a backward-facing sloping wedge. Typically, the bottom of a garbage bin is supported and reinforced by crisscrossing beams. In this embodiment, the crossbeams 102 and longitudinal beams 101 are positioned to match the beams at the bottom of the garbage bin. During the process of lowering the garbage bin into its installation position, the positioning wedges can automatically position it in the front-back direction, ensuring that the mounting holes on the longitudinal beams 101 automatically align with the garbage bin, thus improving installation convenience.

[0066] Reference Figure 6 In some embodiments of this utility model, a rubber sheet 204 is rotatably provided at the front end of the garbage bin 200. In the first state, the rubber sheet 204 hangs freely from the front end of the garbage bin 200. In the second state, the rubber sheet 204 flips towards the garbage container under the action of gravity, covering the upper gap between the garbage bin 200 and the garbage container, reducing odor leakage. In the first state, it also prevents pedestrians or other objects from colliding with the front end of the garbage bin 200 and being injured.

[0067] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
