Description

Technical Field

[0001] This invention belongs to the field of waste unloading technology, specifically a device for unloading solid waste. Background Technology

[0002] Solid waste refers to solid, semi-solid, gaseous, or containerized substances that are generated during production, daily life, and other activities and have lost their original utilization value, or that have been discarded or abandoned even if they have not lost their utilization value. It also includes items and substances that are subject to waste management as stipulated by laws and administrative regulations. In the treatment of solid waste, it is necessary to first crush and sort it, then collect the different types of solid waste separately, and finally recycle them uniformly. When recycling solid waste, it needs to be unloaded at a recycling facility.

[0003] Existing systems combine unloading and collection functions into a single device (such as a conveyor truck). This device collects sorted solid waste and transports it to a recycling system, where it directly dumps the waste into the system's inlet for reuse. However, waste typically accumulates inside the conveyor truck, and its weight causes it to compress against each other. During dumping, some solid waste can easily become stuck, requiring manual cleaning and resulting in a long unloading time. Furthermore, because one end of the truck needs to be raised during unloading, if solid waste becomes stuck, the excessive height of the truck can cause it to tilt, creating a safety hazard. Therefore, improvements are needed. Summary of the Invention

[0004] To address the issues raised in the background art, such as the need for manual cleaning when solid waste gets stuck in the truck bed, which is time-consuming, and the potential safety hazard of the truck bed being tilted if unloading is not smooth, the present invention provides a solid waste unloading device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a solid waste unloading device, comprising a carriage, and further comprising: A pushing mechanism, which is installed on the inner wall of the carriage, is used to push the solid waste in the carriage out. A material plate pushing mechanism is located at the bottom of the carriage and is used to push the material pushing mechanism to move for unloading. A rotating mechanism is provided at the unloading end of the carriage; A blocking mechanism is mounted on a rotating mechanism and blocks the unloading end of the car body. The second hydraulic cylinder is located on both sides of the carriage, and the second hydraulic cylinder drives the sealing mechanism to rotate through the rotating mechanism; The material pushing mechanism includes a first material pushing plate and a second material pushing plate. One end of the first material pushing plate is hinged to the second material pushing plate, and the other end is hinged to the carriage. The material pushing mechanism is placed inside the carriage.

[0006] Preferably, the material plate pushing mechanism includes a push plate, rollers and a first hydraulic cylinder. The push plate is hinged to the carriage, the rollers are installed at both ends of the push plate, and the fixed end of the first hydraulic cylinder is hinged to the bottom of the carriage and the movable end is hinged to the push plate.

[0007] Preferably, the pusher plate is in the shape of a right angle, and when the pusher plate rotates, it can squeeze the first pusher plate to flip over. The surface of the carriage is provided with a channel that allows the pusher plate to enter.

[0008] Preferably, the rotating mechanism includes a connecting plate and a one-way rotating assembly. The connecting plate is fixedly connected to the sealing mechanism, fixed to the surface of the one-way rotating assembly, and located inside the carriage.

[0009] Preferably, the unidirectional rotation assembly includes a connecting shaft, a sleeve, a ratchet, a pawl, and a connecting plate. The connecting shaft is rotatably connected to the carriage and fixedly connected to the connecting plate. The ratchet, sleeve, and connecting plate are symmetrically arranged along the surface of the connecting shaft from the middle to both ends. The ratchet and the connecting plate are both fixedly connected to the connecting shaft. The sleeve is fixedly installed on the outside of the carriage and rotatably connected to the connecting shaft. The pawl is hinged inside the sleeve and can restrict the unidirectional rotation of the ratchet by its own weight. The connecting plate is eccentrically hinged to the movable end of the second hydraulic cylinder.

[0010] Preferably, the sealing mechanism includes a sealing door plate, a spring damper, and a third pusher plate. The sealing door plate and the third pusher plate are slidably connected. One end of the spring damper is fixedly connected to the sealing door plate, and the other end is fixedly connected to the third pusher plate.

[0011] Preferably, the third pusher plate is in contact with the bottom surface of the inner cavity of the carriage in a vertical state, and the spring damper is in a compressed state at this time.

[0012] Preferably, the blocking door panel includes a plate body, an elastic element, and a locking block. The plate body is fixedly connected to the rotating mechanism, and the locking block slides elastically at both ends of the plate body through the elastic element. A locking groove adapted to the locking block is provided on the inner side wall of the unloading end of the carriage.

[0013] Preferably, the first pusher plate is provided with a magnet that can attract the first pusher plate to the inner wall of the carriage, and the first pusher plate and the second pusher plate can block the passage opened on the carriage at any time.

[0014] Preferably, both the first pusher plate and the second pusher plate are clearance-fitted with the two side walls of the inner cavity.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention drives the push plate to rotate through the first hydraulic cylinder. One end of the push plate can push the first push plate to flip. The first push plate and the second push plate work together to push the solid waste stuck in the carriage. At the same time, the other end of the push plate can lift one end of the carriage, apply a weight to the solid waste inside the carriage, and promote the discharge effect.

[0016] During the rotation of the sealing mechanism driven by the second hydraulic cylinder, the third pusher plate slides sequentially along the first pusher plate, the second pusher plate and the bottom surface of the inner cavity of the carriage, pushing out the remaining solid waste in the carriage that cannot be discharged by its own weight, thus achieving complete discharge of solid waste and saving labor costs and time.

[0017] This invention first uses a first and a second pusher plate to discharge some of the solid waste inside the carriage, and then raises one end of the carriage, reducing the total weight of the remaining solid waste inside the carriage. This makes raising one end of the carriage safer and prevents the support end from leaving the ground, making it safer to use. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 8 As shown, the present invention provides an unloading device for solid waste, including a carriage 100, and further comprising: The material pushing mechanism 200 is installed on the inner wall of the carriage 100 and is used to push the solid waste inside the carriage 100 out. The material plate pushing mechanism 300 is located at the bottom of the carriage 100 and is used to push the material pushing mechanism 200 to move for unloading. Rotating mechanism 400 is located at the unloading end of the carriage 100; The sealing mechanism 500 is mounted on the rotating mechanism 400 and seals the unloading end of the carriage 100. The second hydraulic cylinder 600 is located on both sides of the carriage 100. The second hydraulic cylinder 600 drives the sealing mechanism 500 to rotate through the rotating mechanism 400. The material pushing mechanism 200 includes a first material pushing plate 210 and a second material pushing plate 220. One end of the first material pushing plate 210 is hinged to the second material pushing plate 220 and the other end is hinged to the carriage 100. The material pushing mechanism 200 is placed inside the carriage 100. The first material pushing plate 210 and the second material pushing plate 220 are both clearance-fitted with the two side walls of the inner cavity of the 100.

[0022] The above scheme is adopted: the second hydraulic cylinder 600 drives the sealing mechanism 500 to flip upward through the rotating mechanism 400, thereby opening the unloading end of the carriage 100. The material plate pushing mechanism 300 pushes the first pushing plate 210 to flip, so that the solid waste located inside the carriage 100 is pushed by the first pushing plate 210 and the second pushing plate 220, and thus discharged through the unloading end of the carriage 100, realizing the function of active discharge and preventing some solid waste from getting stuck inside the carriage 100.

[0023] like Figure 3As shown, the material plate pushing mechanism 300 includes a push plate 310, a roller 320, and a first hydraulic cylinder 330. The push plate 310 is hinged to the carriage 100, and the roller 320 is installed at both ends of the push plate 310. The fixed end of the first hydraulic cylinder 330 is hinged to the bottom of the carriage 100, and the movable end is hinged to the push plate 310. The push plate 310 is generally right-angled. When the push plate 310 rotates, it can squeeze the first push plate 210 to flip. The surface of the carriage 100 is provided with a channel that allows the push plate 310 to enter. The first push plate 210 is provided with a magnet that can attract the first push plate 210 to the inner wall of the carriage 100. The first push plate 210 and the second push plate 220 can block the channel opened on the carriage 100 at any time.

[0024] The above scheme employs the following: the first hydraulic cylinder 330 drives the pusher plate 310 to rotate, which can both push the first pusher plate 210 to flip and lift one end of the carriage 100. The flipping of the first pusher plate 210 pushes the solid waste inside the carriage 100. When the carriage 100 is lifted, it applies a self-weight to the solid waste, promoting its discharge. The first pusher plate 210 and the second pusher plate 220 always cover the channel opened on the carriage 100, preventing solid waste from falling in. The magnets installed on the first pusher plate 210 can ensure contact between the first pusher plate 210 and the inner wall of the carriage 100 without additional pressure, facilitating reloading after unloading. Reinforcing ribs can be added to the first pusher plate 210 and the second pusher plate 220 to increase their strength according to the specific load-bearing capacity required.

[0025] like Figure 5 and Figure 6 As shown, the rotating mechanism 400 includes a connecting plate 410 and a one-way rotating assembly 420. The connecting plate 410 is fixedly connected to the sealing mechanism 500 and is fixed to the surface of the one-way rotating assembly 420. The connecting plate 410 is located inside the carriage 100. The one-way rotating assembly 420 includes a connecting shaft 421, a sleeve 422, a ratchet 423, a pawl 424, and a connecting disc 425. The connecting shaft 421 is rotatably connected to the carriage 100 and fixed to the connecting plate 410. The ratchet 423, the sleeve 422, and the connecting plate 425 are symmetrically arranged from the middle to both ends along the surface of the connecting shaft 421. The ratchet 423 and the connecting plate 425 are both fixedly connected to the connecting shaft 421. The sleeve 422 is fixedly installed on the outside of the carriage 100 and is rotatably connected to the connecting shaft 421. The pawl 424 is hinged inside the sleeve 422 and can restrict the ratchet 423 from rotating in one direction by its own weight. The connecting plate 425 is eccentrically hinged to the movable end of the second hydraulic cylinder 600.

[0026] The above scheme is adopted: the second hydraulic cylinder 600 can drive the connecting plate 425 to rotate, thereby driving the connecting plate 410 and ratchet 423 to rotate through the connecting shaft 421, thereby realizing the flipping of the sealing mechanism 500. The ratchet 424 can limit the ratchet 423 to rotate only in one direction. With the cooperation of the second hydraulic cylinder 600, the sealing mechanism 500 as a whole can achieve unidirectional rotation.

[0027] like Figure 4 As shown, the sealing mechanism 500 includes a sealing door plate 510, a spring damper 520, and a third pusher plate 530. The sealing door plate 510 and the third pusher plate 530 are slidably connected. One end of the spring damper 520 is fixedly connected to the sealing door plate 510, and the other end is fixedly connected to the third pusher plate 530. In the vertical state, the third pusher plate 530 abuts against the bottom surface of the inner cavity of the carriage 100, and at this time the spring damper 520 is in a compressed state.

[0028] Using the above scheme: After the sealing mechanism 500 is flipped over, under the action of the spring damper 520, the third pusher plate 530 slowly slides out of the surface of the sealing door plate 510. As the sealing mechanism 500 rotates as a whole, the sealing door plate 510 and the third pusher plate 530 can cover the top of the carriage 100, playing a certain role in dust prevention. Furthermore, when the solid waste inside the carriage 100 can no longer be discharged by its own weight, the pusher plate 310 rotates back to the position shown in the image. Figure 8 As shown in the diagram, as the sealing mechanism 500 continues to rotate, the third pusher plate 530 slides along the first pusher plate 210, the second pusher plate 220, and the bottom surface of the inner cavity of the carriage 100, pushing out the remaining solid waste in the carriage 100, achieving complete discharge of solid waste, and saving labor costs and time; during the sliding process of the third pusher plate 530 along the first pusher plate 210, the second pusher plate 220, and the bottom surface of the inner cavity of the carriage 100, the spring damper 520 slowly shortens, and the third pusher plate 530 slides again to cover the surface of the sealing door panel 510.

[0029] like Figure 5 As shown, the blocking door panel 510 includes a plate body 511, an elastic element 512, and a locking block 513. The plate body 511 is fixedly connected to the rotating mechanism 400. The locking block 513 slides elastically at both ends of the plate body 511 through the elastic element 512. A locking groove adapted to the locking block 513 is provided on the inner side wall of the unloading end of the carriage 100.

[0030] The above scheme is adopted: when the third pusher plate 530 pushes out the remaining fixed waste in the carriage 100 and is in a vertical state, the locking block 513 engages with the slot opened on the inner side wall of the unloading end of the carriage 100, thereby fixing the overall position of the sealing mechanism 500 and preventing the leakage of solid waste during loading.

[0031] Working principle and usage process of this invention: Initially, the carriage 100, the pushing mechanism 200, and the sealing mechanism 500 work together to form a top-opening chamber, into which solid waste is filled. During unloading, the second hydraulic cylinder 600 is first driven to rotate the connecting shaft 421, ratchet 423, and connecting plate 410 via the connecting plate 425. The rotation of the connecting plate 410 causes the sealing mechanism 500 to flip upwards, thus removing the sealing of the unloading end of the carriage 100. Subsequently, the first hydraulic cylinder 330 drives the push plate 310 to rotate. The upper end of the push plate 310 presses the first push plate 210 through the roller 320. The first push plate 210 is flipped by the pressure, simultaneously causing the second push plate 220 to move. The movement of the first pusher plate 210 and the second pusher plate 220 can push the solid waste inside the carriage 100 toward the unloading end, thereby realizing the discharge of materials. It can also push some of the stuck solid waste. As the pusher plate 310 continues to rotate, the upper end of the pusher plate 310 can no longer push the solid waste inside the carriage 100 through the first pusher plate 210. At this time, the lower end of the pusher plate 310 contacts the ground through the roller 320 and raises one end of the carriage 100. At this time, the solid waste inside the carriage 100 is discharged by its own weight. When the solid waste in the carriage 100 is completely discharged or cannot be discharged by its own weight, the first hydraulic cylinder 330 pulls the push plate 310 back to the position shown. Figure 8 As shown, the second hydraulic cylinder 600 drives the sealing mechanism 500 to continue rotating in one direction. The third pusher plate 530 slides sequentially along the bottom surface of the first pusher plate 210, the second pusher plate 220 and the inner cavity of the carriage 100, pushing out the remaining solid waste in the carriage 100, thus achieving complete discharge of solid waste. When the third pusher plate 530 is in a vertical state, the locking block 513 engages with the slot opened on the inner side wall of the unloading end of the carriage 100, and the second hydraulic cylinder 600 stops driving. At this time, the relative position between the sealing mechanism 500 and the carriage 100 is fixed. Then, the first hydraulic cylinder 330 pulls the pusher plate 310 back to its original position. Under the attraction of the magnet on the first pusher plate 210 and its own weight, the first pusher plate 210 and the second pusher plate 220 can also return to their original positions.
