[0023] In some scenarios, for example, inside a material sorting machine in scenarios such as ore sorting, during the process of the belt transporting materials, situations such as material spillage and material jamming may occur. When the materials are large, there may be a situation where large materials strike. In some related technologies, a retaining edge structure composed of sheet metal parts, rubber sheets, and brushes is used to prevent material spillage. However, the brushes are prone to wear, causing the dust and particulate matter on the belt to spill, and the rubber sheets standing upright may also cause material jamming, resulting in material loss, low conveying efficiency, and the baffle being easily damaged by large materials striking, shortening the service life.

[0024] To overcome the problems existing in the related technologies, an exemplary embodiment of the present disclosure provides a belt retaining edge mechanism 100, as Figure 1 , Figure 4 , Figure 5 shown, which is applied to a belt transmission mechanism. The belt transmission mechanism may include: a belt 300 and frames 200 located on both sides of the belt. Among them, there may be two or more rollers mounted on the frames 200; the belt 300 is sleeved on the rollers, and the rotation of the rollers realizes the conveyance of the belt 300. The belt retaining edge mechanism 100 may include: a bracket 110, a rubber sheet 120, and a support rib plate 130.

[0025] The bracket 110 may be in a plate-like structure, may extend along the belt conveying direction, and may be provided above the outer edge of the belt 300. The bracket 110 may include an inclined portion 111, and the upper side of the inclined portion 111 may be inclined outwardly with respect to the belt 300. The material of the bracket 110 may have relatively high strength and hardness, and can withstand the strike of large pieces of materials, and may be a sheet metal part, etc. The bracket 110 may be a long strip-shaped plate extending along the belt conveying direction and may be provided on both sides of the belt 300 along the belt conveying direction. The brackets 110 on both sides of the belt 300 may be provided with inclined portions 111. The upper side of the inclined portion 111 deviates from the belt 300, and the lower side of the inclined portion 111 is close to the belt 300. The inclined portions 111 of the frame 110 are integrally inclined above the outer edge of the belt 300. The back side of the bracket 110 is close to the frame 200 and is fixedly connected to the frame 200. The fixed connection method may be bolt connection, etc.

[0026] The rubber sheet 120 can be in a sheet structure and can extend along the belt conveying direction. The upper part of the rubber sheet 120 can be fixed to the surface of the inclined part 111 of the support 110 facing the inner side of the belt. The lower end of the rubber sheet 120 can be used to abut against the belt 300 and can be used to prevent the materials conveyed on the belt 300 from moving outward of the belt 300. The rubber sheet 120 can be in a sheet structure with a thickness of 5-10 millimeters, and can have good wear resistance, elasticity and load-bearing capacity. The length of the rubber sheet 120 can be set to be the same as the length of the support 110. A plurality of rubber sheets 120 can be provided. The plurality of rubber sheets 120 can be connected and arranged along the belt conveying direction. The plurality of rubber sheets 120 can overlap each other to ensure that the plurality of rubber sheets 120 can form a sealed structure to prevent the overflow of materials during the transmission of materials. The rubber sheet 120 can be arranged on the side of the support 110 facing the belt 300 and can be fixed to the surface of the inclined part 111 of the support 110. The fixing method can be bolt connection or the like.

[0027] The support rib plate 130 can be fixedly arranged on the back side of the inclined part 111 of the support 110 and can be used to be fixedly connected to the machine frame 200 to support the support 110. There can be one support rib plate 130 or there can be a plurality of support rib plates 130. The plurality of support rib plates 130 can support the support 110 more firmly. The support rib plate 130 can be in the shape of a triangular plate, a column, etc. One end of the support rib plate 130 is fixedly connected to the back side of the inclined part 111 of the support 110, and one end is fixedly connected to the machine frame 200 and can be used to support the support 110, which can improve the stability of the belt edge retaining mechanism 100. The material of the support rib plate 130 can be stainless steel or the like, which can enhance the support strength, make the belt edge retaining mechanism 100 more stable and can withstand the impact of large pieces of materials.

[0028] In the embodiments of the present disclosure, a belt edge retaining mechanism 100 is provided, and the brush is cancelled, which can avoid the overflow of materials from the belt 300 during transportation after the brush is damaged and can reduce the material cost. By placing the support 110 obliquely, the gap between the belt edge retaining mechanism 100 and the belt 300 can be reduced, effectively avoiding the situation of material jamming. The rubber sheet 120 is abutted against the belt 300, and can still be abutted against the belt 300 after the rubber sheet 120 is worn, preventing the overflow of materials. The support rib plate 130 supports the support 110, which can withstand the impact of large-size and heavy materials, improving the overall stability of the belt edge retaining mechanism 100. The belt edge retaining mechanism 100 can effectively prevent the overflow of dust and particulate matter during the transmission of materials by the belt 300, avoid the situation of material jamming, reduce the probability of faults, improve the strength of the whole belt edge retaining mechanism 100, can withstand the impact of large materials, improve the transmission efficiency, increase the material sorting output, increase the stability of the whole belt edge retaining mechanism 100 and extend the service life.

[0029] In some embodiments, such asFigure 1 , Figure 3 , Figure 4 As shown in Figure 1 , Figure 3 , and Figure 4 , the support rib plate 130 can be in the shape of a triangular plate and can be arranged vertically. The first side of the support rib plate 130 facing the bracket 110 is fixedly connected to the back side of the inclined portion 111 of the bracket 110. The second side of the support rib plate 130 facing away from the bracket 110 and the third side at the bottom are respectively used for fixedly connecting to the frame 110. The support rib plate 130 can be vertically arranged on the back side of the bracket 110 and can be in the shape of a triangular plate. The first side of the support rib plate 130 is fixedly connected to the back side of the bracket 110, and the fixed connection method can be welding or the like, which can ensure that the bracket 110 will not lose strength due to carrying materials, friction, or long-term fatigue, and plays a role in supporting the bracket 110. The second side of the support rib plate 130 facing away from the bracket 110 is fixedly connected to the vertical beam of the frame 200, which can provide horizontal support for the bracket 110. The third side of the support rib plate 130 facing away from the bracket 110 is fixedly connected to the horizontal cross beam extending from the frame 200, which can provide vertical support for the bracket 110. The support rib plate 130 can withstand the impact of materials from different directions, and the overall shape is a triangular plate, with a relatively stable structure, not easily deformed or broken, and can withstand a large impact force. The fixed connection method can be welding, bolt connection, etc., and the frame 200 can provide a reliable fixed fulcrum for the support rib plate 130. In the embodiments of the present disclosure, by setting the support rib plate 130, one end is fixedly connected to the bracket 110, and the other end is fixedly connected to the frame 200, which can support the bracket 110, improve the strength of the entire belt side guard mechanism 100, be resistant to large material impacts, prevent the bracket 110 from displacing or deforming due to belt load or vibration, ensure the long-term operation of the belt side guard mechanism 100, and improve the conveying efficiency.

[0030] In some embodiments, such as Figure 1 , Figure 2 , Figure 4As shown, the belt edge retaining mechanism 100 may further include: a mounting member 140, which can pass through the rubber sheet 120 and be fixedly connected to the inclined portion 111 of the bracket 110, and can press and fix the rubber sheet 120 on the surface of the inclined portion 111 facing the inner side of the belt 300. The mounting member 140 can be a flat iron sheet metal. Such materials have high strength and are impact-resistant. It is arranged on the side of the belt edge retaining mechanism 100 facing the belt 300. For the impact of large-weight materials that may be received, it can avoid damage and ensure the stable and reliable installation of the rubber sheet 120. The mounting member 140 can be connected to the bracket 110 through the rubber sheet 120 by bolts, clamps or other mechanical fasteners, playing a role in fixing the rubber sheet 120. Through the mounting member 140, it can be ensured that the rubber sheet 120 can be firmly fixed on the inclined portion 111 of the bracket 110, ensuring that the rubber sheet 120 will not shift or loosen. The mounting member 140 can press and fix the rubber sheet 120 on the surface of the inclined portion 111 facing the inner side of the belt 300, and can be used to prevent materials from scattering from the edge of the belt 300. In the embodiments of the present disclosure, by setting the mounting member 140 to pass through the rubber sheet 120 and be fixedly connected to the bracket 110, it is convenient to fix the rubber sheet 120, which can effectively prevent material overflow and provide edge protection.

[0031] In some embodiments, as Figure 1 , Figure 4 shown, the bracket 110 may further include a mounting portion 112, which can be arranged at the upper end of the inclined portion 111. The mounting portion 112 can be provided with a frame mounting hole; the belt edge retaining mechanism 100 may further include a mounting bolt, which can be used to pass through the mounting hole and be fixedly connected to the frame 200. In the embodiments of the present disclosure, a mounting portion 112 can be provided at the upper end of the inclined portion 111. The mounting portion 112 can be fixedly connected to the inclined portion 111 or integrally formed with the inclined portion 111. In some embodiments, the mounting portion 112 and the inclined portion 111 can be sheet metal parts, and the mounting portion 112 and the inclined portion 111 with a certain included angle are formed by bending. In the actual scenario, the mounting portion 112 can be arranged substantially vertically and fixedly connected to the frames 200 on both sides of the belt 300; at the same time, the inclined portion 111 at a certain angle with the mounting portion 112 is inclined with respect to the vertical direction and extends from the lower end of the mounting portion 112 towards the lower side and the center of the belt 300 for supporting the rubber sheet 120. One or more mounting holes can be provided on the mounting portion 112, and the bracket 110 and the frame 200 can be fixed by passing the mounting bolt through the mounting hole. The installation is convenient and facilitates later maintenance and adjustment. In the embodiments of the present disclosure, by providing mounting holes on the mounting portion 112 and fixing the bracket 110 and the frame 200 together by means of bolt connection, the structural stability can be improved. When the position of the belt edge retaining mechanism 100 needs to be adjusted, the design of the mounting holes is also adapted to more application scenarios, enhancing the flexibility of the belt edge retaining mechanism 100.

[0032] In some embodiments, asFigure 1 , Figure 2 As shown in Figure 2 , the belt edge retaining mechanism 100 may include a plurality of rubber sheets 120, which may be arranged in sequence along the belt conveying direction; the belt edge retaining mechanism 100 may further include: a connecting member 150, which may be disposed between two adjacent rubber sheets 120 and fix the two adjacent rubber sheets 120. In the embodiments of the present disclosure, to meet the length of the belt 300, especially in the case of a relatively long conveying distance, the belt edge retaining mechanism 100 may be provided with a plurality of rubber sheets 120, and each rubber sheet 120 is arranged in sequence along the belt conveying direction, and they may be overlapped or in clearance fit with each other. For example, in an ore separator, the identification mechanism needs to identify the ore on the belt 300, so a certain conveying distance is required. The length of the belt 300 is relatively long. By arranging a plurality of rubber sheets 120 in sequence, the cost can be reduced and it is convenient for replacement. The plurality of rubber sheets 120 may be arranged in sequence along the belt conveying direction, and two adjacent rubber sheets 120 may be connected to each other, and the two adjacent rubber sheets 120 may be fixed together by the connecting member 150. The connecting member 150 may be a belt screw buckle or the like, which can ensure the strength and durability of the connecting member 150. The connection method may be bolts, nuts or buckles, which is convenient for installation and subsequent maintenance. The connecting member 150 may extend towards the belt direction, completely cover or partially cover the connection area of the adjacent rubber sheets 120, improve the connection strength, and prevent materials from overflowing between the adjacent rubber sheets 120. In the embodiments of the present disclosure, by connecting a plurality of rubber sheets 120 together through the connecting member 150, it can effectively prevent the conveyed materials from falling during transportation. By designing the detachable rubber sheets and the connecting member 150, it can be regularly inspected and replaced, which is convenient for maintenance. Selecting wear-resistant materials for the connecting member 150 can extend the service life and reduce the maintenance cost.

[0033] In some embodiments, as Figure 1 , Figure 2 shown, the ends of two adjacent rubber sheets 120 overlap, and may be fixed by the connecting member 150. The ends of the adjacent rubber sheets 120 may be designed to overlap, which can ensure the formation of a continuous edge when conveying materials, and can effectively prevent the conveyed materials from falling during transportation. The overlapping length may be 2-5 cm, which can ensure stability and will not generate friction due to being too long. Moreover, through overlapping, there is an overlapping part between the adjacent rubber sheets 120, which is convenient for the fixation of the connecting member 150 and makes the installation of the adjacent rubber sheets 120 more stable. In the embodiments of the present disclosure, by designing the ends of the two rubber sheets 120 to overlap, it can ensure that the materials will not overflow during transportation, enhance the firmness of the overall structure, help improve the service life of the system, and reduce the maintenance cost.

[0034] In some embodiments, the lower end of the rubber 120 may be provided with an extension portion, which can be used for running-in and wear with the belt 300. The lower end of the rubber 120 can be extended to an additional length to form an extension portion for running-in and wear with the belt 300. After installation, the extension portion gradually wears out through running-in with the belt 300, ensuring that the lower end of the rubber is in close contact with the belt 300. In the embodiment of the present disclosure, by providing an extension portion at the lower end of the rubber 120 for running-in and wear with the belt, the rubber 120 can fit tightly with the belt to prevent material from overflowing during transportation. Regularly checking the wear of the extension portion and replacing it when necessary can ensure that the rubber maintains an effective side guard function.

[0035] In some embodiments, the acute angle between the rubber 120 and the belt 300 can be 45-70 degrees. The rubber 120 and the belt 300 are set at a certain tilt angle, which can maintain the contact between the lower end of the rubber 120 and the belt 300 to avoid gaps, and can effectively prevent material from overflowing when the material moves toward the outside. The upper end of the rubber 120 of the present disclosure extends outward, and the entire body is tilted. The angle formed by the back side of the rubber 120 (the side away from the center of the belt 300) and the plane of the surface of the belt 300 can be an acute angle, that is, the side of the rubber 120 facing the center of the belt 300 (that is, the side used to block the material) forms an obtuse angle with the surface of the belt 300. If the acute angle between the rubber 120 and the belt 300 is too small, the blocking effect of the rubber 120 is reduced, and the material is easily moved upward and outward along the surface of the rubber 120, resulting in the possibility of material overflow during transportation. If the acute angle between the rubber 120 and the belt is too large, the rubber 120 will tend to be placed vertically, which can easily create gaps at the bottom and cause large pieces of material to become stuck. In the disclosed embodiment, the acute angle between the rubber 120 and the belt 300 can be 45-70 degrees, and can specifically be set to 50 degrees, 60 degrees, etc. In the disclosed embodiment, the appropriate angle between the rubber 120 and the belt can effectively prevent material overflow and jams, and can also effectively adjust the belt's load-bearing strength, reducing impact on the equipment.

[0036] Based on the same inventive concept, Figure 5 As shown, the embodiment of the present disclosure also provides a belt transmission mechanism, wherein the belt transmission mechanism may include: a frame 200, a roller, a belt 300 and the belt dam mechanism 100 of any one of the aforementioned embodiments. The frame 200 can play a supporting role. The two ends of the roller are supported on the frame 200, and there can be one or more rollers. The belt 300 is sleeved on the outside of the roller, and the belt 300 can be driven by the rotational movement of the roller to transmit materials. The belt dam mechanism 100 can be arranged on both sides of the belt 300, and can be used to prevent material from overflowing; wherein, the bracket 110 of the belt dam mechanism 100 can be fixedly arranged on the frame 200 on both sides of the belt 300, and the lower end of the rubber 120 can be in contact with the belt 300.

[0038] Based on the same inventive concept, an exemplary embodiment of the present disclosure further provides a sorting machine that can be used for material sorting, including: a belt transmission mechanism, an identification mechanism, and a sorting mechanism as described in any one of the foregoing embodiments.

[0039] The belt transmission mechanism can be used to convey materials. The belt transmission mechanism can be a conveyor belt or the like, and materials can be placed on the belt transmission mechanism, and the materials are conveyed to the identification mechanism through the belt transmission mechanism.

[0040] The identification mechanism can be used to identify the materials conveyed by the belt transmission mechanism.

The sorting mechanism can be arranged downstream of the belt transmission mechanism, and the sorting mechanism can sort materials according to the categories of the materials, so that different categories of materials are separated from each other.

[0042] Through the sorting machine of the embodiments of the present disclosure, materials can be conveyed through the belt transmission mechanism, which is convenient for the identification and classification of the identification mechanism. Based on the identification and classification of the materials by the identification mechanism, and finally, different types of materials are sorted according to the sorting mechanism, which can accurately and quickly classify and sort the materials to be tested, and has high identification accuracy and sorting accuracy.
