Description

Technical Field

[0001] The invention relates to the technical field of conveying devices, and in particular to a conveying device for crushed magnetite. Background Art

[0002] Magnetite ore, as an indispensable raw material for the production of magnets, is crushed into small pieces in the post-mining processing flow. These small pieces need to be transported to the designated location through efficient and stable conveying devices in the subsequent processing to ensure the smooth operation of the production line. However, in actual operation, especially when the small pieces need to be transported across a height difference, the traditional method is often to dump the small pieces directly from a high place onto the conveying device. Since the magnetite ore small pieces themselves have a certain weight and hardness, this direct drop method will produce a huge impact force on the conveying device, which will not only damage the conveying device, but also may affect the stability of the entire production line.

[0003] In summary, the magnetite ore crushing material conveying device of the present invention effectively solves the problems of large impact force and easy damage to equipment in the traditional conveying method, and provides an efficient, stable and reliable crushing material conveying solution for the magnetite ore processing industry. Summary of the invention

[0004] In view of the above-mentioned technical deficiencies, the object of the present invention is to provide a magnetite ore crushing material conveying device, which can play a buffering effect during the falling process of the magnetite ore crushing materials.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a magnetite crushed material conveying device, comprising:

[0006] A feeding unit, the feeding unit comprising a feeding barrel;

[0007] A conveying unit, the conveying unit comprising a bracket and a conveying belt installed inside the bracket and arranged along a conveying direction, the conveying unit comprising a buffer section and a conveying section, the buffer section being installed inside a feeding barrel, and the conveying section being a section structure capable of conveying magnetite ore crushed materials;

[0008] Among them, the connection between the buffer section and the conveying section is a bending part, and an energy absorbing device is provided inside the bending part. The energy absorbing device includes a plurality of energy absorbers arranged along the bending direction of the bending part, and each of the energy absorbers includes two buffer columns with buffering function. One end of the buffer column is rotatably mounted on the bracket. When the middle part of the energy absorber is subjected to pressure, the two buffer columns rotate in the direction away from the pressure source, thereby absorbing and dispersing the pressure.

[0009] Preferably, the energy absorbing device also includes a support column rotatably mounted on the bracket and a support plate fixed inside the bracket, the support column is installed at the outer bend of the bending part, the buffer column is installed at the inner bend of the bending part, and a guide plate is rotatably mounted inside the bracket in the middle of the bending part, and the guide plate simultaneously rests against the inner bend of the bending part and the conveyor belt.

[0010] Preferably, the energy absorbing device also includes a center roller, which includes a supporting roller and a rotating roller, the rotating roller is sleeved on the outside of the supporting roller, the center roller is located in the middle of the two buffer columns, and is hinged to the buffer columns through a connecting rod structure, the center roller is rotatably installed on a slide, and the slide is slidably inserted into the support plate along a vertical direction.

[0011] Preferably, the buffer column includes an inner rod, an outer roller and a sliding rod, one end of the inner rod is rotatably mounted on the bracket, one end of the sliding rod is slidably mounted inside the inner rod through an elastic body, and the other end of the sliding rod extends to the outside of the inner rod and is connected to the buffer column through the connecting rod structure.

[0014] Preferably, the conveying unit further comprises two driving rollers, which are respectively arranged at two ends of the conveying unit, and the two driving rollers are rotatably mounted on a bracket, and a motor for driving the driving rollers to rotate is fixed on the bracket.

[0015] Preferably, the conveying section and the buffer section are both located inside the conveyor belt and are rotatably mounted with rollers.

[0016] Preferably, a support body is fixed to the upper end of the feed barrel, and an inlet communicating with the feed barrel is provided on the support body.

DETAILED DESCRIPTION

[0028] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0029] Embodiment 1

[0030] like Figure 1 and Figure 2As shown, in this embodiment, a magnetite ore crushing material conveying device is provided, including a feeding unit and a conveying unit. The feeding unit includes a feeding barrel 1, which is firmly mounted on the upper part of the feeding unit, and its main function is to serve as an inlet passage for the ore crushing materials. The ore crushing materials are introduced into its internal space through the top of the feeding barrel 1. The design flexibility of the feeding barrel 1 is reflected in that its top can be coordinated with different environments or facilities: on the one hand, it can be flush with the ground, in which case the matching conveying device will extend underground accordingly to receive the ore crushing materials from below the surface; on the other hand, if the top of the feeding barrel 1 is kept at the same horizontal height as the storage device for the ore crushing materials, it means that the storage device is set at a higher position, and the workers only need to simply pour the ore crushing materials from the storage device into the entrance of the feeding barrel 1 to efficiently complete the feeding process. Such a design not only takes into account the terrain restrictions in practical applications, but also optimizes the convenience of operation. A support body is fixed to the upper end of the feed barrel 1, and an inlet connected to the feed barrel 1 is provided on the support body, and ore fragments can enter the feed barrel 1 from the inlet.

[0031] The conveying unit includes a bracket 6 and a conveyor belt 2 installed inside the bracket 6 and arranged along the conveying direction. The bracket 6 is a supporting component of the conveying unit. The bracket 6 includes two symmetrically arranged side plates that can support other components of the conveying unit. The conveyor belt 2 surrounds the entire conveying unit in a closed loop form to form a continuous conveying path. During operation, the conveyor belt 2 can continuously and efficiently convey the ore crushed materials from one end to the other end, thereby realizing the stable and continuous conveying function of the ore crushed materials. This design ensures the smoothness and efficiency of the ore crushed materials during the conveying process. The conveying unit includes a buffer section 3 and a conveying section 4. The conveying section 4 and the buffer section 3 are located inside the conveyor belt 2 and are both rotatably installed with rollers. The rollers play a key supporting role in the conveying unit, ensuring that the conveyor belt 2 maintains a stable shape during operation and avoids unnecessary deformation. The buffer section 3 is installed inside the feeding barrel 1. The buffer section 3 is designed as a vertical structure with an inclined angle to reduce the impact force when the ore crushed materials fall. When the ore waste slides down the inclined surface of the buffer section 3, due to its inclination angle, most of the waste will first contact and stay on the inclined surface. This design cleverly utilizes the unloading effect of the inclined surface, effectively disperses and reduces the impact force generated by the direct fall of the ore waste, thereby realizing the protection of the subsequent processing equipment and the stability of the waste transmission process. The conveying section 4 is a section structure that can convey magnetite ore fragments. After the ore waste falls into one end of the conveying section 4, it is immediately received by the equipment in this section and transmitted to the next process. This process design is intended to efficiently connect the previous and next processes, ensuring that the ore waste can be smoothly and orderly transferred to the subsequent processing links, thereby facilitating the use and processing of the subsequent processes.

[0032] The conveying unit also includes two driving rollers, which are respectively arranged at both ends of the conveying unit, and the two driving rollers are rotatably installed on the bracket 6. A motor for driving the driving rollers to rotate is fixed on the bracket 6. The motor can drive the driving rollers to rotate, and the rotational movement of the driving rollers further promotes the conveyor belt 2 to convey.

[0033] Among them, the connection between the buffer section 3 and the conveying section 4 is a bending part, and an energy absorbing device is arranged inside the bending part. When the ore waste falls downward from the buffer section 3, there is a part of the ore waste that does not contact the surface of the buffer section 3 and falls directly downward. Moreover, the ore waste in contact with the buffer section 3 will also have a certain impact force. Although this impact force is reduced, it will also exert an impact force on the conveying unit. After working for a long time, this impact force will also cause damage to the rigid conveyor belt 2. The energy absorbing device includes a plurality of energy absorbers arranged along the bending direction of the bending part. The energy absorber includes two buffer columns 5 with a buffering function. One end of the buffer column 5 is rotatably mounted on the bracket 6. When the middle part of the energy absorber is subjected to pressure, the two buffer columns 5 are rotated in the direction away from the pressure source, thereby absorbing and dispersing the pressure. The two buffer columns 5 are located on opposite sides of the middle part of the conveyor belt 2. Since most of the ore fragments are concentrated in the middle area of ​​the conveyor belt 2 during the falling process, the impact force generated also mainly acts on this position. At this time, the opposite ends of the two buffer columns 5 just bear this part of the impact force. By rotating in the direction away from the impact source, the impact force is effectively unloaded, thereby protecting the conveyor belt 2 and its supporting structure from damage caused by direct impact.

[0034] Embodiment 2

[0035] like Figure 1-Figure 6 As shown, based on the first embodiment, this embodiment provides a structure of an energy absorbing device, which is as follows:

[0036] The energy absorption device includes a support column rotatably mounted on the bracket 6 and a support plate 8 fixed inside the bracket 6. The support column is installed at the outer bend of the bending part, and the buffer column 5 is installed at the inner bend of the bending part. The bracket 6 is located in the middle of the bending part and is rotatably mounted with a guide plate 7. The guide plate 7 is against the inner bend of the bending part and the conveyor belt 2 at the same time. Due to the physical characteristics and the requirements of the running trajectory, the conveyor belt 2 will form an inner bend angle. If there is a lack of appropriate support structure in this inner bend angle area, the conveyor belt 2 may become loose due to uneven tension, thereby affecting the transmission efficiency and stability. To solve this problem, the guide plates 7 are applied to the conveyor belt 2. They can effectively support the part of the conveyor belt 2 at the inner bend angle, ensuring that even when the conveyor belt 2 is kept properly tensioned, the conveyor belt 2 can be allowed to form the necessary bending position inside. In this way, the guide plate 7 not only maintains the stability of the conveyor belt 2, but also ensures the smooth transmission of materials.

[0037] The energy absorption device also includes a center roller 13, which includes a support roller 16 and a rotating roller. A bearing is connected between the support roller 16 and the rotating roller to ensure that the rotating roller can rotate freely. The rotating roller is sleeved on the outside of the support roller 16, and the rotating roller can rotate freely. The center roller 13 is located in the middle of the two buffer columns 5. The center roller 13 is placed in the middle of the conveyor belt 2. This position ensures that the center roller 13 can effectively provide support for the conveyor belt 2. At the same time, the support roller 16 works in conjunction with the buffer columns 5 distributed on both sides of the conveyor belt 2 to jointly maintain the stable operation of the conveyor belt 2. When the middle of the conveyor belt 2 encounters external pressure, one end of the buffer column 5 on both sides will rotate accordingly after being compressed, which serves as a buffer mechanism to reduce the impact on the conveyor belt 2 and the central roller 13 in the middle, thereby protecting the stability of the entire conveying system, and is hinged with the buffer column 5 through the connecting rod structure 9. The central roller 13 is rotatably mounted on the slide 14. The slide 14 includes a sliding block and a side rod. The number of the side rods is two. The two side rods are supported at both ends of the central roller 13 respectively, and are used to support the central roller 13. The slide 14 is slidably inserted into the support plate 8 along the vertical direction. The slide 14 is designed as a support structure for the central roller 13, and the support roller 16 slides freely in the internal space of the support plate 8. During the sliding adjustment process of the central roller 13, the connection with the buffer columns 5 on both sides is continuously maintained through the connecting rod structure 9.

[0038] The end of the slide 14 extending into the support plate 8 is a conical surface, and the support plate 8 has a support column 15 slidably installed on both sides of the slide 14. The support column 15 is slidably installed on the support plate 8 through an elastic body, and the end of the support column 15 connected to the slide 14 is adapted through a wedge structure. Under the action of the elastic body, the support column 15 applies a force to the slide 14, and this force gives the slide 14 an upward potential energy. This potential energy not only enhances the stability of the slide 14, but also provides a key support for the buffer column 5, thereby achieving an effective buffering effect.

[0039] Embodiment 3

[0040] like Figure 1-Figure 6 As shown, based on the first and second embodiments, this embodiment provides a buffering method for the buffer column 5, which is as follows:

[0041] The buffer column 5 includes an inner rod 10, an outer roller 11 and a slide bar 12. One end of the inner rod 10 is rotatably mounted on the bracket 6. The buffer column 5 achieves a buffering effect by rotating the inner rod 10. This design enables the rotation of the inner rod 10 to be directly converted into a corresponding rotation of the buffer column 5 when subjected to external pressure or adjustment is required, thereby playing a role in buffering and adjustment. The outer roller 11 is rotatably sleeved on the outside of the inner rod 10, and the inner rod 10 cannot rotate by itself. The outer roller 11 sleeved on the inner rod 10 is in contact with the conveyor belt 2, and the conveyor belt 2 is in contact with the conveyor belt 2. During the process, the outer roller 11 will rotate following the transmission of the conveyor belt 2. A bearing is connected between the outer roller 11 and the inner rod 10. One end of the slide rod 12 is slidably installed inside the inner rod 10 through an elastic body, and the other end of the slide rod 12 extends to the outside of the inner rod 10 and is connected to the buffer column 5 through a connecting rod structure 9. After the buffer column 5 is compressed, the buffer column 5 is deformed. When the center roller 13 is displaced, the slide rod 12 is pulled to move through the connecting rod structure 9. The slide rod 12 overcomes the tension of the spring and slides outward for a distance, thereby achieving a buffering effect.

[0042] The connecting rod structure 9 includes a connecting rod, one end of which is hinged to the end of the sliding rod 12, and the other end is hinged to the support roller 16. The function of the connecting rod is to allow the angle between the inner rod 10 and the support roller 16 to be adjusted. A conical clearance groove is provided at one end of the inner rod 10 close to the support roller 16 to prevent the connecting rod from contacting and getting stuck with the support roller 16.

[0043] Working principle:

[0044] The magnetite ore fragments enter from the top of the feed barrel 1 and first slide naturally along the inclined buffer section 3. This design allows most of the fragments to smoothly reach the conveyor belt 2 below. The conveyor belt 2 serves as the first buffer layer, effectively reducing the impact of the fragments falling. Subsequently, the fragments continue to move along the conveyor belt 2 to the bending part of the conveying unit.

[0045] When the broken materials reach the bending part, they will produce a small impact force on the built-in buffer column 5 and the center roller 13. This impact force causes the slide 14 connected to the center roller 13 to move inside the support plate 8, forming a dynamic response mechanism. In this process, the center roller 13 drives the buffer column 5 to rotate through its unique connecting rod structure 9, and at the same time drives the slide rod 12 to slide smoothly inside the inner rod 10. This action is not only smooth and efficient, but more importantly, they cause the deformation of the elastic body in a linked manner, thereby producing a significant buffering effect.

[0046] This buffering force generated by the deformation of the elastic body forms an effective protective barrier at the bend, significantly reducing the direct impact of the magnetite ore fragments on the equipment structure. Finally, after this series of buffering treatments, the fragments can smoothly pass through the bend and continue to be transported forward along the conveying section 4, ensuring the smoothness and safety of the entire transmission process.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
