Description

Technical Field

[0001] The invention relates to the field of waste recycling and treatment, and in particular to a lifting and conveying structure for waste recycling and treatment. Background Art

[0002] Waste refers to garbage generated by human beings in production, consumption, life and other activities. Its shape, strength and other properties vary greatly. For example, among the waste generated in industrial production, there are plastic wastes with relatively low strength, which are granular and blocky in shape, and metal wastes with relatively high strength, most of which are irregular in shape. In the process of recycling and processing, these wastes inevitably require the use of lifting and conveying machinery to pull these wastes to the preset height.

[0003] Based on the lifting and transportation of waste, the applicant has found some prior arts through searching, which are introduced one by one:

[0004] The Chinese invention patent with application publication number CN115159022A discloses a lifting and conveying structure for hazardous waste treatment, which uses a screw conveyor to pull the waste to a preset height, and adjusts the height of the discharge port of the screw conveyor through an adjustment mechanism. There are some shortcomings: the essence of a screw conveyor is to pull objects to move through an auger or a push screw. For wastes with small volume and low strength such as plastic particles, they can be easily pulled and moved, but for metal wastes with irregular shapes and large volumes, it is difficult to pull and move them through a screw conveyor, which can easily cause damage to the auger.

[0005] The Chinese invention patent with authorization announcement number CN116022527B discloses an automated lifting conveyor for solid waste, and the Chinese utility model patent with authorization announcement number CN217866522U discloses a conveying height adjustment device for a belt conveyor. Both of these existing documents use a conveyor belt to pull the waste to move. Although there are no problems in the above-mentioned screw conveyor technology, there are still some shortcomings: the conveyor belt is arranged inclined as a whole. If the final pulling height of the waste is high, then the slope of the conveyor belt needs to be adjusted to be steeper, which can easily cause the waste to slip on the conveyor belt. In order to avoid the slipping problem, the slope of the conveyor belt needs to be set to be gentler and the length to be set to be longer, which has the problem of occupying too much floor space.

[0006] Based on the above, the present invention proposes a lifting and conveying structure for waste recycling and processing, which has a simplified structure and occupies a small area and can be applied to different types of waste. Summary of the invention

[0007] In order to solve the problems mentioned in the above background, the present invention provides a lifting and conveying structure for waste recycling and processing.

[0008] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows.

[0009] A lifting and conveying structure for waste recycling and processing comprises a frame and a transfer box. Two conveyor belts are installed on the frame. The conveying directions of the two conveyor belts are both arranged horizontally and perpendicular to each other. The two conveyor belts are respectively a first conveyor belt and a second conveyor belt. The discharge end of the first conveyor belt is located above the opening of the transfer box on the second conveyor belt.

[0010] Two sets of vertical traction components are installed on the frame, and the two sets of vertical traction components are respectively located at the two ends of the second conveyor belt. A connecting bridge plate is arranged between the two sets of vertical traction components, and a notch is opened on the connecting bridge plate. A guide nozzle arranged in an inclined manner extends from the lower opening of the notch. The vertical traction component can receive the transfer box and make the transfer box move in the vertical direction in a state where the lower opening is blocked;

[0011] A telescopic rod is also installed on the frame, and the telescopic rod is used to push the transfer box on the vertical traction assembly to the connecting bridge plate. When the transfer box is located at the position of the notch, the lower opening of the transfer box is opened.

[0012] Furthermore, the vertical traction assembly includes traction components, which are provided in two groups and are respectively located on both sides of the second conveyor belt along the conveying direction. Each group of traction components includes two synchronous belts distributed along the conveying direction of the second conveyor belt. The traction direction of the synchronous belt is arranged vertically, and the bandwidth direction of the synchronous belt is parallel to the conveying direction of the second conveyor belt. A support is provided on the outer surface of the synchronous belt and a number of support are arranged in an array along the extension direction of the synchronous belt.

[0013] Furthermore, the upper and lower ends of the transfer box are open, and the lower open end of the transfer box is provided with an annular groove, a bottom plate is hingedly installed in the annular groove, and a hinge axis formed at the hinged installation position is parallel to the conveying direction of the second conveyor belt, and two bottom plates are provided and are respectively located on both sides of the lower opening of the transfer box along the conveying direction of the second conveyor belt. Initially, the bottom plate is supported, the upper end surface of the bottom plate is in contact with the bottom of the annular groove, and the lower end surface of the bottom plate is flush with the lower open end of the transfer box, and the free ends of the two bottom plates are in contact to block the lower opening of the transfer box;

[0014] Side seats are extended from both sides of the transfer box along the width direction of the second conveyor belt, and the lower end surfaces of the side seats are flush with the lower opening end of the transfer box.

[0015] Furthermore, when each of the four synchronous belts of the vertical traction assembly has a support seat that is flush with the upper surface of the second conveyor belt, the second conveyor belt can pull the transfer box onto the four supports. At this time, the bottom plate is in contact with the support seats, the support seats support the transfer box and the bottom plate keeps the lower opening of the transfer box blocked.

[0016] Furthermore, a slot is provided on the side of the bracket facing the second conveyor belt. When the lower slot wall of the slot of a bracket on each of the four synchronous belts of the vertical traction assembly is flush with the upper surface of the second conveyor belt, the second conveyor belt can pull the transfer box onto the four brackets. At this time, the bottom plate contacts the lower slot wall of the slot, the bracket supports the transfer box and the bottom plate keeps the lower opening of the transfer box blocked.

[0017] Furthermore, the two sets of vertical traction assemblies are respectively a right vertical traction assembly located at the feeding end of the second conveyor belt and a left vertical traction assembly located at the discharging end of the second conveyor belt;

[0018] The connecting bridge plate includes a supporting plate, and the two sides of the supporting plate along the width direction of the second conveyor belt are provided with side plates extending vertically upward, the distance between the two side plates is equal to the size of the transfer box along the width direction of the second conveyor belt, and a bracket is provided at the connection between the side plate and the supporting plate, and the bracket is used to avoid the side seat;

[0019] The distance between the two hole walls of the notch along the width direction of the second conveyor belt is equal to the distance between the two groove walls of the annular groove along the width direction of the second conveyor belt. The hole wall of the notch along the conveying direction of the second conveyor belt and close to the right vertical traction component is composed of two inclined walls. The distance between the two inclined walls decreases along the conveying direction of the second conveyor belt and from the left vertical traction component to the right vertical traction component. The inclined wall itself is in the shape of an inclined surface. The distance between the inclined surface and the hole opening of the notch decreases along the horizontal direction, which is perpendicular to the length direction of the inclined wall and from the left vertical traction component to the right vertical traction component.

[0020] Furthermore, when the lower opening of the transfer box on the left vertical traction assembly is flush with the upper end surface of the connecting bridge plate, the transfer box can be pushed onto the connecting bridge plate through the telescopic rod, the transfer box fits against the side plate and the side seat is inserted into the bracket.

[0021] Furthermore, the outer surface of the second conveyor belt is provided with ribs, the extension direction of the ribs is parallel to the bandwidth direction of the second conveyor belt, and a plurality of ribs are arranged in an array along the extension direction of the second conveyor belt. When the second conveyor belt is running, the transfer box is pushed to move by the ribs.

[0022] Furthermore, a support roller is arranged in the second conveyor belt, the support roller is movably connected to the frame, the support roller is parallel to the bandwidth direction of the second conveyor belt, the support roller contacts the inner surface of the second conveyor belt, and a plurality of support rollers are arranged in an array along the extension direction of the second conveyor belt.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] In this solution, the waste can be lifted and transported and the final height of the waste can be adjusted. On this basis:

[0025] 1. This solution uses a transfer box as a loading tool for waste during the lifting and transportation process. Therefore, during the lifting and transportation process, it can be applied to different types of waste. In addition, in this solution, the transfer box loaded with waste is directly lifted from the vertical direction, so the floor space is small, thus solving the problem of the limitation of the types of waste that can be lifted and transported by the screw conveyor and the problem of the large floor space occupied by the conveyor belt lifting and transportation mentioned in the background technology;

[0026] 2. In this solution, the lower opening of the transfer box is blocked by the bottom plate. During the lifting process of the transfer box, the bottom plate is supported by the cooperation of the second conveyor belt and the bracket, so that the bottom plate can keep blocking the transfer box. When the transfer box moves to the gap connecting the bridge plate, the bottom plate automatically deflects under the action of gravity, and the lower opening of the transfer box is opened to dump the waste into the guide nozzle. After that, under the lifting action of the inclined wall of the gap, the bottom plate is reset and the lower opening of the transfer box is blocked again. Therefore, this solution simplifies the structure of opening or closing the lower opening of the transfer box, making the structure of this solution simpler and more convenient to operate.

[0027] It is easy for a person skilled in the art to think of using a motor or other technology to drive the bottom plate to open or close the lower opening of the transfer box, or using a series of mechanical linkage structures to drive the bottom plate to open or close the lower opening of the transfer box. The former is difficult to power because the transfer box is constantly moving, and the latter requires a series of additional mechanical structures, which is relatively complicated.

[0028] On the other hand, in the present solution, during the movement of the transfer box, the support, the connecting bridge plate and the second conveyor belt are indispensable structures for realizing the movement of the transfer box. On this basis, the shape and structure of the support, the connecting bridge plate, the transfer box and the bottom plate are improved, so that the state switching of the transfer box at different positions can be realized without the need for additional mechanical or electrical structures, thereby simplifying the structure.

DETAILED DESCRIPTION

[0044] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0045] Reference Figure 1-Figure 13 , a lifting and conveying structure for waste recycling and processing, including a frame and a transfer box 700.

[0046] Two conveyor belts are installed on the frame: a first conveyor belt 100 and a second conveyor belt 200. The conveying directions of the two conveyor belts are arranged horizontally and perpendicular to each other. When the transfer box 700 is located on the second conveyor belt 200, the discharge end of the first conveyor belt 100 is located above the opening of the transfer box 700. The outer surface of the second conveyor belt 200 is provided with ribs 201. The extension direction of the ribs 201 is parallel to the bandwidth direction of the second conveyor belt 200. A number of ribs 201 are arranged in an array along the extension direction of the second conveyor belt 200. When the second conveyor belt 200 is running, the transfer box 700 can be pushed to move by the ribs 201.

[0047] Two groups of vertical traction components are installed on the frame, and the two groups of vertical traction components are respectively located at the two ends of the second conveyor belt 200. A connecting bridge plate 500 is arranged between the two groups of vertical traction components. A notch 501 is opened on the connecting bridge plate 500, and an inclined material guide nozzle 600 extends from the lower hole of the notch 501.

[0048] Among the two groups of vertical traction components, for the convenience of description, the one located at the feeding end of the second conveyor belt 200 is named as the right vertical traction component, and the one located at the discharging end of the second conveyor belt 200 is named as the left vertical traction component, wherein the left vertical traction component is used to receive and pull the transfer box 700 on the second conveyor belt 200 to move upward in the vertical direction, and the right vertical traction component is used to receive and pull the transfer box 700 on the connecting bridge plate 500 to move downward in the vertical direction. In addition, when the second conveyor belt 200 is running, the transfer box 700 can be pushed to the left vertical traction component through the rib 201, but the connecting bridge plate 500 cannot. Therefore, a telescopic rod 400 is also installed on the frame, which is used to push the transfer box 700 on the left vertical traction component to the connecting bridge plate 500 and to push the transfer box 700 on the connecting bridge plate 500 to the right vertical traction component. The telescopic rod 400 can be an existing electric telescopic rod technology or an existing linear screw stepper motor technology, etc., which will not be elaborated.

[0049] It should be noted that when the transfer box 700 is located at the notch 501, the material inside will fall downward into the material guide nozzle 600 and be guided to the next process through the material guide nozzle 600. That is, the material guide nozzle 600 is the lifting and conveying height of the waste in this solution. In addition, the core of this solution is the lifting and conveying of the waste. As for the next process, it is not the core of this solution and will not be elaborated. In addition, the connecting bridge plate 500 is installed on the frame by existing bolt technology, and the position height of the connecting bridge plate 500 can be adjusted, and the lifting and conveying height of the waste can be adjusted.

[0050] Further, see Figure 3 and Figure 4The vertical traction assembly includes traction components. There are two groups of traction components and they are respectively located on both sides of the second conveyor belt 200 along the conveying direction. Each group of traction components includes two synchronous belts 300 distributed along the conveying direction of the second conveyor belt 200. The traction direction of the synchronous belt 300 is vertically arranged, and the bandwidth direction of the synchronous belt 300 is parallel to the conveying direction of the second conveyor belt 200. In this way, the vertical traction assembly is composed of four synchronous belts 300, which are distributed in pairs on both sides of the second conveyor belt 200.

[0051] In addition, a support 301 is provided on the outer surface of the synchronous belt 300 and a plurality of support 301 are arranged in an array along the extension direction of the synchronous belt 300. When the support 301 is flush with the upper surface of the second conveyor belt 200, the second conveyor belt 200 runs, and the transfer box 700 on the second conveyor belt 200 can be pulled onto the support 301 of the four synchronous belts 300. Then, the four synchronous belts 300 run synchronously, that is, the transfer box 700 is pulled to move, or the transfer box 700 supported by the support 301 on the four synchronous belts 300 is pulled to the second conveyor belt 200.

[0052] Further, see Figure 5-Figure 7 The upper and lower ends of the transfer box 700 are open, and an annular groove 702 is provided at the lower open end of the transfer box 700. A bottom plate 701 is hingedly installed in the annular groove 702. The hinge axis formed at the hinged installation is parallel to the conveying direction of the second conveyor belt 200. Two bottom plates 701 are provided and are respectively located on both sides of the lower opening of the transfer box 700 along the conveying direction of the second conveyor belt 200. Initially, the upper end surface of the bottom plate 701 is in contact with the bottom of the annular groove 702, and the lower end surface of the bottom plate 701 is flush with the lower open end of the transfer box 700. The free ends of the two bottom plates 701 are in contact to block the lower opening of the transfer box 700.

[0053] Side seats 703 are extended from both sides of the transfer box 700 along the width direction of the second conveyor belt 200 , and the lower end surface of the side seat 703 is flush with the lower opening end of the transfer box 700 .

[0054] When the transfer box 700 is located on the second conveyor belt 200 , the hinge shaft is located outside the second conveyor belt 200 .

[0055] There are two ways for the bracket 301 to support the transfer box 700: first, the bracket 301 is rectangular in shape. When the transfer box 700 is located at the discharge end of the second conveyor belt 200, in the left vertical traction assembly, the upper end faces of four brackets 301 are flush with the upper surface of the second conveyor belt 200, that is, flush with the lower opening end of the transfer box 700, and the bottom plate 701 is in contact with the bracket 301, that is, the bracket 301 can support the transfer box 700 by supporting the side seat 703. The bracket 301 supports the bottom plate 701, thereby limiting the downward deflection of the bottom plate 701, so that the bottom of the transfer box 700 remains blocked by the bottom plate 701; second, referring to Figure 8 A slot is provided on the side of the bracket 301 facing the second conveyor belt 200. Similarly, when the transfer box 700 is located at the discharge end of the second conveyor belt 200, in the left vertical traction assembly, the lower slot walls of the slots on four brackets 301 are flush with the upper surface of the second conveyor belt 200, and the bottom plate 701 is in contact with the lower slot walls of the slots.

[0056] Reference Figure 10-13 The connecting bridge plate 500 includes a pallet, and side panels extend vertically upward on both sides of the pallet along the bandwidth direction of the second conveyor belt 200. The distance between the two side panels is equal to the size of the transfer box 700 along the bandwidth direction of the second conveyor belt 200. A bracket 502 is provided at the connection between the side panel and the pallet, and the bracket 502 is used to avoid the side seat 703.

[0057] The distance between the two hole walls of the notch 501 along the bandwidth direction of the second conveyor belt 200 is equal to the distance between the two groove walls of the annular groove 702 along the bandwidth direction of the second conveyor belt 200. The hole wall of the notch 501 along the conveying direction of the second conveyor belt 200 and close to the right vertical traction component is composed of two inclined walls. The distance between the two inclined walls decreases along the conveying direction of the second conveyor belt 200 and from the left vertical traction component to the right vertical traction component. The inclined wall itself is in the shape of an inclined surface. The distance between the inclined surface and the hole opening of the notch 501 decreases along the horizontal direction, and the horizontal direction is perpendicular to the length direction of the inclined wall and points from the left vertical traction component to the right vertical traction component.

[0058] When the lower opening of the transfer box 700 on the left vertical traction assembly is flush with the upper end surface of the connecting bridge plate 500, the transfer box 700 can be pushed onto the connecting bridge plate 500 through the telescopic rod 400, the transfer box 700 is fitted with the side plate and the side seat 703 is inserted into the bracket 502. At the beginning, since the upper end of the connecting bridge plate 500 supports the lower opening of the transfer box 700 and the bottom plate 701, the transfer box 700 is smoothly pushed to the connecting bridge plate 500 and the lower opening remains blocked. When the transfer box 700 comes to the position of the notch 501, refer to Fig.12 and Fig.13At this time, since the distance between the two hole walls of the notch 501 along the bandwidth direction of the second conveyor belt 200 is equal to the distance between the two groove walls of the annular groove 702 along the bandwidth direction of the second conveyor belt 200, the connecting bridge plate 500 withdraws its support for the bottom plate 701, and the bracket 502 maintains its support for the side seat 703. Therefore, under the action of gravity, the bottom plate 701 deflects downward around the hinge axis, thereby opening the lower opening of the transfer box 700, and the waste in the transfer box 700 falls into the guide nozzle 600. Then, the telescopic rod 400 continues to push the transfer box 700 to move. During this process, the inclined wall of the notch 501 moves relative to the transfer box 700. During the relative movement, the bottom plate 701 can be lifted upward by the inclined wall of the notch 501, so that the bottom plate 701 re-blocks the lower opening of the transfer box 700. Finally, the transfer box 700 will be pushed to the four brackets 301 of the right vertical traction assembly.

[0059] Working principle of the present invention:

[0060] First, the first conveyor belt 100 pulls the waste to fall into the transfer box 700 on the second conveyor belt 200. At the same time, the synchronous belts 300 in the two sets of vertical traction assemblies are running. Each of the four synchronous belts 300 in each set of vertical traction assemblies has a bracket 301 flush with the upper surface of the second conveyor belt 200.

[0061] Then, the transfer box 700 loaded with waste is pulled by the second conveyor belt 200 to the location of the four brackets 301 of the left vertical pulling assembly, and the empty transfer box 700 on the right vertical pulling assembly is pulled to below the discharge end of the first conveyor belt 100;

[0062] Then, the synchronous belt 300 of the left vertical traction assembly pulls the transfer box 700 loaded with waste to move upward until the lower opening of the transfer box 700 loaded with waste is flush with the upper end surface of the connecting bridge plate 500;

[0063] Then, the transfer box 700 is pushed onto the connecting bridge plate 500 through the telescopic rod 400. When the transfer box 700 is located at the position of the notch 501, under the action of gravity, the bottom plate 701 deflects downward, and the waste in the transfer box 700 falls into the guide nozzle 600. The telescopic rod 400 continues to push the transfer box 700 to move. During this process, the inclined wall of the notch 501 moves relative to the transfer box 700. During the relative movement, the bottom plate 701 can be lifted upward by the inclined wall of the notch 501, so that the bottom plate 701 re-blocks the lower opening of the transfer box 700. Finally, the transfer box 700 will be pushed onto the four brackets 301 of the right vertical traction assembly, and the transfer box 700 will be towed downward by the right vertical traction assembly to wait for the next use.

[0064] Preferably, in order to prevent gravity from causing the second conveyor belt 200 to sag and affect its operation after the waste enters the transfer box 700, a support roller can be provided in the second conveyor belt 200. The support roller is movably connected to the frame, and the support roller is parallel to the bandwidth direction of the second conveyor belt 200. The support roller contacts the inner surface of the second conveyor belt 200. A number of support rollers are arranged in an array along the extension direction of the second conveyor belt 200, and the second conveyor belt 200 is supported by the support roller to prevent the transfer box 700 from pressing the second conveyor belt 200.

[0065] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
