Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belt buffering, and particularly relates to a buffering device for ore conveyor belts. Background Technique

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain exploitable properties. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in ore is called the ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are commonly expressed in percentages. The subsequent processing after ore mining requires the use of conveyor belts for transportation. However, due to the heavy weight of the ore, a large impact force will be generated when it falls onto the conveyor belt. In order to avoid damage or tearing of the conveyor belt and prevent material scattering, a buffer bed is used.

[0003] However, in actual use, since the buffer bed relies on the buffer strips on its surface for buffering and does not have its own buffering ability, the supporting plate structure at the bottom is prone to deformation and damage after long-term impact, reducing the service life of the buffer bed. Moreover, the anti-overflow plates on both sides do not have the ability to adjust the angle, which brings inconvenience during use. Therefore, there is room for improvement. Content of the Utility Model

[0004] The utility model provides a buffering device for ore conveyor belts to solve the problems raised in the background technique.

[0005] To solve the above problems, the present utility model provides a buffer device for a mineral material conveyor belt, which includes a base, a first buffer plate, and a second buffer plate. Two symmetrically arranged limiting grooves are respectively formed at the left and right ends of the base. A first fixed seat is fixedly installed at the left end of the base, and a second fixed seat symmetric to the first fixed seat is fixedly installed at the right end. A bidirectional threaded lead screw is rotatably connected between the first fixed seat and the second fixed seat, and one end of the bidirectional threaded lead screw threadedly penetrates through the second fixed seat, and a driving handle is installed at the end. The first buffer plate is arranged in the middle of the base above the bidirectional threaded lead screw, and the bottom of the first buffer plate is connected to the base through a plurality of spring shock absorbers. Two symmetrically arranged hinge seats are respectively installed on both sides of the first buffer plate in the base. The second buffer plate is composed of two plates arranged on the base and located on both sides of the first buffer plate. Two connecting plates corresponding to the hinge seats are symmetrically arranged on the bottom surface of the second buffer plate, and the connecting plates are hinged to the hinge seats. Two sliding grooves are symmetrically installed above the connecting plates on the bottom surface of the second buffer plate. A shock-absorbing plate is slidably connected to the bottom surface of the second buffer plate through the two sliding grooves. A plurality of shock-absorbing rods are equidistantly fixedly connected to the bottom surface of the shock-absorbing plate. One end of the shock-absorbing rod away from the shock-absorbing plate slidably penetrates through a positioning plate. A spring is sleeved in the shock-absorbing rod, and the spring is located between the shock-absorbing plate and the positioning plate. A support column is respectively connected below both ends of the positioning plate. The support column is slidably connected to the base. A driving plate is installed below between the two support columns. The driving plate is threadedly connected to the bidirectional threaded lead screw.

[0006] Preferably: T-shaped connection blocks are arranged on the upper surfaces of the first buffer plate and the second buffer plate, and buffer strips are connected in the T-shaped connection blocks.

[0007] Preferably: Two guide rods are fixedly arranged between the first fixed seat and the second fixed seat and are located on both sides of the bidirectional threaded lead screw. The driving plate is slidably connected to the two guide rods.

[0008] Preferably: On both side surfaces of each limiting groove in the base, two semi-circular guide sliding strips with the same length as the limiting groove are respectively arranged. A connecting seat is arranged at the bottom of the support column. The connecting seat is in an inverted U shape and is slidably sleeved on the base, and the connecting seat is slidably connected to the guide sliding strips on both side surfaces in the base. A limiting block connected to the limiting groove is arranged in the connecting seat.

[0009] The beneficial effects of adopting the above technical solutions are:

[0010] 1. Rotate the bidirectional threaded lead screw in the first fixed seat and the second fixed seat by driving the driving handle. Then, drive the support column to move and slide in the base through the driving plate. The support column drives the positioning plate to move. The positioning plate cooperates with the shock-absorbing column and the spring to drive the shock-absorbing plate to move in the chute of the second buffer plate, so as to adjust the angle of the second buffer plate. And through the cooperation of the bidirectional threaded lead screw and the driving plate, the two second buffer plates move synchronously, making the adjusted angle more convenient and stable.

[0011] 2. Support the first buffer plate through a number of spring shock absorbers. At the same time, when the pressure is too high, the spring shock absorbers will reduce the impact force of the first buffer plate, thereby avoiding deformation or damage of the first buffer plate caused by impact and extending its service life.

[0012] 3. The shock-absorbing rod cooperates with the spring to absorb the shock when the second buffer plate is impacted, avoiding deformation or damage of the second buffer plate caused by impact and extending the service life of the second buffer plate. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0019] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a movable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] Such as Figures 1-3, in this embodiment, a buffer device for a mineral conveyor belt includes a base 1, a first buffer plate 2, and a second buffer plate 3. Two symmetrically arranged limit grooves 13 are respectively formed at the left and right ends of the base 1. A first fixed seat 11 is fixedly installed at the left end of the base 1, and a second fixed seat 12 symmetric to the first fixed seat 11 is fixedly installed at the right end. A bidirectional threaded lead screw 4 is rotatably connected between the first fixed seat 11 and the second fixed seat 12, and one end of the bidirectional threaded lead screw 4 is threadedly passed through the second fixed seat 12, and a driving handle 41 is installed at the end. The first buffer plate 2 is arranged in the middle of the base 1 above the bidirectional threaded lead screw 4, and the bottom of the first buffer plate 2 is connected to the base 1 through a plurality of spring shock absorbers 21. Two symmetrically arranged hinge seats 14 are respectively installed on both sides of the first buffer plate 2 in the base 1. The second buffer plate 3 is composed of two parts arranged on the base 1 and located on both sides of the first buffer plate 2. Two connecting plates 31 corresponding to the hinge seats 14 are symmetrically arranged on the bottom surface of the second buffer plate 3, and the connecting plates 31 are hinged to the hinge seats 14. Two sliding grooves 32 are symmetrically installed above the connecting plates 31 on the bottom surface of the second buffer plate 3. A shock-absorbing plate 5 is slidably connected to the bottom surface of the second buffer plate 3 through the two sliding grooves 32. A plurality of shock-absorbing rods 51 are equidistantly fixedly connected to the bottom surface of the shock-absorbing plate 5. One end of the shock-absorbing rod 51 away from the second buffer plate 3 is slidably passed through a positioning plate 52. A spring 53 is sleeved on the shock-absorbing rod 51, and the spring 53 is located between the shock-absorbing plate 5 and the positioning plate 52. A support column 54 is fixedly connected to the lower parts of both ends of the positioning plate 52. The support column 54 is slidably connected to the base 1. A driving plate 55 is installed between the lower parts of the two support columns 54. The driving plate 55 is threadedly connected to the bidirectional threaded lead screw 4.

[0021] Through the above technical solution, when in use, the device is installed in the conveyor belt through the base 1. The bidirectional threaded lead screw 4 is driven by the driving handle 41 to rotate, thereby driving the driving plate 55 to move in the bidirectional threaded lead screw 4. The movement of the driving plate 55 drives the support column 54 to slide in the base 1, thereby driving the positioning plate 52 to move. The positioning plate 52 drives the shock-absorbing plate 5 to slide in the sliding groove 32 on the bottom surface of the second buffer plate 3 through the cooperation of the shock-absorbing rod 51 and the spring 53. The angle of the second buffer plate 3 in the base 1 is adjusted by sliding the adjustment hinge, and the two second buffer plates 3 are adjusted synchronously, making the adjustment more stable and convenient. When buffering the conveyor belt, the spring shock absorber 21 with greater resistance is used to replace the original support frame, so that the first buffer plate 2 has a certain elasticity. When the impact force is too large, the spring shock absorber 21 provides shock absorption for the first buffer plate 2, thereby preventing the first buffer plate 2 from being impacted and deformed or damaged, and extending the service life of the first buffer plate 2. When the second buffer plates 3 on both sides of the first buffer plate 2 are impacted, when the impact force is too large, it is transmitted to the shock-absorbing plate 5. The shock-absorbing plate 5 can provide shock absorption for the second buffer plate 3 through the cooperation of the shock-absorbing rod 51, the spring 53 and the positioning plate 52, thereby preventing the second buffer plate 3 from being impacted and deformed or damaged, and extending the service life.

[0022] Preferably: T-shaped connecting blocks 61 are provided on the upper surfaces of the first buffer plate 2 and the second buffer plate 3, and buffer strips 6 are connected in the T-shaped connecting blocks 61.

[0023] Preferably: Two guide rods 42 are fixedly provided between the first fixed seat 11 and the second fixed seat 12, and are located on both sides of the bidirectional threaded lead screw 4. The driving plate 55 is slidably connected to the two guide rods 42.

[0024] Through the above technical solution, the arrangement of the guide rod 42 is used to ensure the stability of the movement of the driving plate 55.

[0025] Preferably: On both side surfaces of each limiting groove 13 in the base 1, two semi-circular guide sliding strips 15 with the same length as the limiting groove 13 are respectively provided. A connecting seat 56 is provided at the bottom of the support column 54. The connecting seat 56 is a reverse U-shaped sliding sleeve on the base 1, and the connecting seat 56 is slidably connected to the guide sliding strips 15 on both sides in the base 1. A limiting block connected to the limiting groove 13 is provided in the connecting seat 56.

[0026] Through the above technical solution, the arrangement of the semi-circular guide sliding strip 15 facilitates the sliding connection between the connecting seat 56 and the base 1, ensures the stability of the sliding, and at the same time performs limiting to prevent the connecting seat 56 from falling off. The cooperation of the limiting groove 11 and the limiting block of the connecting seat 56 limits the movement range of the support column 53, prevents the connecting seat 56 from falling off the guide sliding strip 15, and ensures the stability of the angle adjustment.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model, rather than limiting the technical solutions described in the present utility model; therefore, although this specification has described the present utility model in detail with reference to the above respective embodiments, however, those of ordinary skill in the art should understand that the present utility model can still be modified or equivalently replaced, and all technical solutions and their improvements that do not depart from the spirit and scope of the present utility model should be covered within the scope of the claims of the present utility model; the technologies not described in detail in the present utility model are implemented with the existing technologies.
