Description

Technical Field

[0001] The present invention relates to the field of ore transportation, and more specifically, to a crushed stone conveyor belt with a shock absorption structure. Background Art

[0002] A conveyor belt, also known as a transport belt, is a rubber, fiber, and metal composite product or a plastic and fabric composite product used to carry and transport materials in a belt conveyor. After the ore is crushed, a conveyor belt is usually used to transport the crushed ore outwards.

[0003] In the prior art, the conveyor belt for transporting crushed stones is usually composed of a support member and a transport belt arranged on the support member. For example, a crushed stone conveyor disclosed in a Chinese invention patent application with the publication number CN111634612A and a crushed stone conveying device for mining disclosed in a Chinese invention patent with the publication number CN107458820B both adopt this structure. This kind of crushed stone conveyor belt composed of a support member and a transport belt arranged on the support member can realize the function of transporting crushed stones. However, crushed stones usually have a large mass and a high falling speed. When they fall onto the conveyor belt, a strong impact force will be generated. When the conveyor belt is subjected to a large impact, the surface material may deform, and cracks, wear, or tearing may occur in the parts that are continuously impacted for a long time. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a crushed stone conveyor belt with a shock absorption structure.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] A crushed stone conveyor belt with a shock absorption structure includes a bracket, a plurality of roller groups fixedly connected to one side of the bracket, two driving rollers rotatably connected inside the bracket, a belt sleeved outside the plurality of roller groups and the two driving rollers, a driving part one fixedly connected to one side of the bracket for driving one of the driving rollers to rotate, and further includes a plurality of buffer seats one fixedly connected to one side of the bracket and located between the roller groups and the bracket;

[0007] A slow feeding part is further connected to one side of the bracket, and the slow feeding part includes two support parts fixedly connected to one side of the bracket and a feeding part fixedly connected to one side of the two support parts;

[0008] The feeding part includes a hollow seat one fixedly connected to one side of two support frames, an opening formed at the lower end of the hollow seat one, and a material supporting and buffering assembly connected to the inner wall of the opening.

The outside of the hollow seat two is connected to the inner wall of the hollow seat one through a buffer structure.

[0012] Furthermore, the buffer structure includes multiple groups of connecting seats one fixedly connected to the inner wall of the hollow seat one, multiple connecting seats two fixedly connected to the outside of the hollow seat two and respectively connected to the multiple groups of connecting seats one, and buffer pads arranged at the connection between the connecting seats two and the connecting seats one.

[0013] Furthermore, two driving parts two are symmetrically fixedly connected to the outer surface of one side of the hollow seat two, and two stirring rollers are symmetrically rotatably connected to the inner wall of the material cavity. The output shafts of the two driving parts two both penetrate through the hollow seat two and extend into the material cavity and are respectively fixedly connected to one end of the two stirring rollers.

[0014] Further, a wetting component is also connected inside the first hollow seat, and the wetting component is located below the second hollow seat. The wetting component includes an inclined plate fixedly connected to the inner wall of the first hollow seat and below the discharge port, two material limiting plates fixedly connected to the upper end of the inclined plate, a first cross plate fixedly connected to the inner wall of the first hollow seat, and a plurality of second atomizing nozzles fixedly connected to one side of the first cross plate. The output ends of the plurality of second atomizing nozzles all face the inclined plate.

[0015] Further, the wetting component further includes a second cross plate fixedly connected to the inner wall of the first hollow seat, a plurality of connecting rods fixedly connected to one side of the second cross plate, slots opened on the left and right sides and the lower end of the plurality of connecting rods, first atomizing nozzles fixedly connected in the slots, and a plurality of liquid supply connectors fixedly connected to the second cross plate and respectively connected to the first atomizing nozzles inside each connecting rod. The other end of the connecting rod is fixedly connected to one side of the inclined plate.

[0016] Further, an air flow deceleration part is also connected to the lower end of the first hollow seat. The air flow deceleration part includes two extension frames symmetrically and fixedly connected to the lower end of the first hollow seat, an adjustment seat rotatably connected to one side of each of the two extension frames at both ends, a jet head and a drainage cover fixedly connected to one side of the adjustment seat, and a second motor fixedly connected to one side of one of the extension frames.

[0017] Further, the plurality of roller groups include a roller frame fixedly connected to one side of the support, two side rollers symmetrically and rotatably connected to both sides of the roller frame, two movable grooves one symmetrically opened on the inner wall of the roller frame, two guide rods respectively fixedly connected to the inner walls of the two movable grooves one, two springs respectively sleeved outside the two guide rods, two sliding seats respectively slidably connected in the two movable grooves one and movably sleeved outside the guide rods, and a middle roller rotatably connected to one side of each of the two sliding seats at both ends. The two ends of the two springs are respectively connected to the sliding seat and the inner wall of the movable groove one.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) In this solution, a material supporting and buffering component is provided. The falling crushed stones can be guided by the supporting plate, so that the crushed stones first contact the surface of the supporting plate before falling onto the conveyor belt. The supporting plate can reduce the falling height of the crushed stones from a high place to a certain extent, reduce the kinetic energy of the material, and prevent excessive impact when contacting the conveyor belt. At the same time, by adjusting the angle of the plate, the falling speed and angle of the crushed stones can be effectively controlled, reducing the impact force of the crushed stones on the conveyor belt. In this way, the impact force generated by the direct fall of the crushed stones onto the conveyor belt can be greatly reduced, reducing the wear and damage of the conveyor belt, and helping to extend the service life of the conveyor belt. Moreover, if the edge of the crushed stone is very sharp, directly contacting the conveyor belt may scratch the surface of the conveyor belt, and through the buffering of the material supporting plate, this risk can be reduced.

[0020] (2) This solution is provided with an edge passivation component. The crushed stones can first fall into the second hollow seat, and the vibration part can drive the second hollow seat to vibrate. During the vibration process, when the crushed stones collide with each other, their edges and surfaces will experience continuous impacts and frictions. These forces can gradually remove the sharp parts on the surface of the crushed stones, grind the sharp edges smooth, and thus become more rounded or passivated. This process can optimize the shape of the crushed stones, reduce the sharp corners or irregularities of the crushed stones, and avoid damage to the conveyor belt caused by the direct contact of the sharp edges of the crushed stones with the conveyor belt.

[0021] (3) This solution is provided with a wetting component. The crushed stones on the inclined plate can be subjected to atomized wetting treatment through the second atomizing nozzle, and the outer surface of the falling crushed stones can be wetted through the first atomizing nozzle. After the crushed stones are uniformly wetted, a thin film of water is formed to cover the surface of the crushed stones, affecting the mutual friction force between the crushed stones. When there is water on the surface of the crushed stones, the water will increase the resistance between the crushed stones and the air. Compared with dry crushed stones, the sliding speed of wet crushed stones will decrease due to the increased friction with the air. This means that the acceleration of the crushed stones during falling will be reduced, thereby reducing the impact force on the conveyor belt. Description of the Drawings

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 to 11, a gravel conveyor belt with a shock-absorbing structure, comprising a bracket 1, a plurality of roller groups 2 fixedly connected to one side of the bracket 1, two driving rollers 4 rotatably connected inside the bracket 1, a belt 3 sleeved outside the plurality of roller groups 2 and the two driving rollers 4, and a first driving part 5 fixedly connected to one side of the bracket 1 for driving one of the driving rollers 4 to rotate. It further includes a plurality of first buffer seats 11 fixedly connected to one side of the bracket 1 and located between the roller groups 2 and the bracket 1; the plurality of roller groups 2 include a roller frame 21 fixedly connected to one side of the bracket 1, two side rollers 22 symmetrically rotatably connected to both sides of the roller frame 21, two first movable grooves 23 symmetrically formed on the inner wall of the roller frame 21, two guide rods 25 respectively fixedly connected to the inner walls of the two first movable grooves 23, two springs 26 respectively sleeved outside the two guide rods 25, two sliding seats 24 respectively slidably connected in the two first movable grooves 23 and movably sleeved outside the guide rods 25, and a middle roller 27 with both ends rotatably connected to one side of the two sliding seats 24, and both ends of the two springs 26 are respectively connected to the sliding seats 24 and the inner walls of the first movable grooves 23.

[0037] A slow-feeding part 6 is further connected to one side of the bracket 1, and the slow-feeding part 6 includes two supporting parts fixedly connected to one side of the bracket 1 and a feeding part 61 fixedly connected to one side of the two supporting parts;

[0038] The feeding part 61 includes a first hollow seat 611 fixedly connected to one side of two support frames 65, an opening 63 formed at the lower end of the first hollow seat 611, and a material-supporting buffer assembly 7 connected to the inner wall of the opening 63. The material-supporting buffer assembly 7 includes a support plate 71 with one end rotatably connected to the inner wall of the opening 63, two second movable grooves 72 symmetrically formed on the inner wall of the opening 63, two lead screws 73 respectively rotatably connected inside the two second movable grooves 72, two screw seats 74 respectively slidably connected to the inner walls of the two second movable grooves 72 and screwed outside the lead screws 73, and two connecting rods 75 respectively rotatably connected to one side of the two screw seats 74, and the other ends of the two connecting rods 75 are respectively rotatably connected to both sides of the support plate 71.

[0039] The supporting part includes two third buffer seats 66 symmetrically fixedly connected to one side of the bracket 1, two support frames 65 respectively fixedly connected to one side of the two third buffer seats 66, and two second buffer seats 64 respectively fixedly connected to one side of the two support frames 65. The two second buffer seats 64 are symmetrically fixedly connected to the lower end of the first hollow seat 611.

[0040] On one side of the hollow seat 611, two first gears 76 are symmetrically and rotatably connected, and two second gears 77 respectively meshing with the two first gears 76 are provided. On one side of each of the two second gears 77, a synchronous pulley 78 is fixedly connected, and the two synchronous pulleys 78 are drivingly connected by a synchronous belt 79. On one side of the hollow seat 611, a protective cover 8 is also fixedly connected, and on one side of the protective cover 8, a first motor 81 is fixedly connected. The output shaft of the first motor 81 penetrates through the protective cover 8 and is fixedly connected to one side of one of the synchronous pulleys 78. One ends of the two lead screws 73 penetrate through the hollow seat 611 and are respectively fixedly connected to the two first gears 76.

[0041] By adopting the above technical solution, crushed stones enter the hollow seat 611 from above the hollow seat 611, are discharged from the opening 63 at the bottom of the hollow seat 611 and fall on the support plate 71. Before the crushed stones fall on the belt 3, they first come into contact with the surface of the support plate 71. The support plate 71 can, to a certain extent, reduce the drop height of the crushed stones falling from a high place, reduce the kinetic energy of the material, so that when it comes into contact with the belt 3, it will not generate too large an impact. Driving the first motor 81 to work can drive one of the synchronous pulleys 78 to rotate. The rotating synchronous pulley 78 drives the other synchronous pulley 78 to rotate through the synchronous belt 79. The two synchronous pulleys 78 drive the two second gears 77 to rotate. The two second gears 77 drive the two first gears 76 and the two lead screws 73 to rotate. When the lead screws 73 rotate, they can drive the lead screw seats 74 to move in the second movable grooves 72. The movement of the lead screw seats 74 can drive the support plate 71 to rotate in the second movable grooves 72 through the connecting rods 75, so as to adjust the angle of the support plate 71. By adjusting the angle of the support plate 71, the falling speed and angle of the crushed stones can be effectively controlled, and the impact force of the crushed stones on the belt 3 can be reduced. In this way, the impact force generated by the crushed stones directly falling on the belt 3 can be greatly reduced, the wear and damage of the belt 3 can be reduced, and it helps to extend the service life of the belt 3. Moreover, if the edges of the crushed stones are very sharp, directly contacting the belt 3 may scratch the surface of the conveyor belt, and through the buffering of the support plate 71, this risk can be reduced.

[0042] As Figures 5 - 7 shown, the feeding part 61 further includes an edge passivation assembly 62 connected to the inside of the hollow seat 611. The edge passivation assembly 62 includes a hollow seat 621 located inside the hollow seat 611, a material cavity 622 opened inside the hollow seat 621, two inclined surfaces 629 opened on the inner wall of the material cavity 622, a material dividing plate 628 fixedly connected to the inner wall of the material cavity 622, a discharge port 623 opened at the lower end of the hollow seat 621 and communicating with the material cavity 622, and two vibration parts 624 symmetrically and fixedly connected to the lower end of the hollow seat 621. The outside of the hollow seat 621 is connected to the inner wall of the hollow seat 611 through a buffer structure.

[0043] The buffer structure includes multiple sets of connecting seats 612 fixedly connected to the inner wall of the hollow seat 611, multiple connecting seats 625 fixedly connected to the outside of the hollow seat 621 and respectively connected to the multiple sets of connecting seats 612, and buffer pads 613 provided at the connection between the connecting seats 625 and the connecting seats 612.

[0044] On one side of the outer surface of the hollow seat 621, two driving parts 626 are symmetrically and fixedly connected, and two stirring rollers 627 are symmetrically and rotatably connected to the inner wall of the material cavity 622. The output shafts of the two driving parts 626 both penetrate through the hollow seat 621 and extend into the material cavity 622 and are respectively fixedly connected to one end of the two stirring rollers 627.

[0045] By adopting the above technical solution, when the crushed stones fall into the hollow seat 611, they will directly fall into the hollow seat 621 inside the hollow seat 611. After being distributed by the material distribution plate 628, the crushed stones respectively fall into both sides inside the hollow seat 621 and slide along the inclined surface 629 towards the direction of the discharge port 623. When the crushed stones are inside the hollow seat 621, the vibration part 624 (a vibration motor can be selected, which belongs to the prior art and will not be elaborated here) works to drive the hollow seat 621 to vibrate, causing the crushed stones inside the hollow seat 621 to vibrate. During the vibration process, when the crushed stones collide with each other, their edges and surfaces will experience continuous impact and friction. These forces can gradually remove the sharp parts on the surface of the crushed stones, grind the sharp edges flat, and thus become smoother or blunter. This process can optimize the shape of the crushed stones, reduce the sharp corners or irregularities of the crushed stones, and avoid damage to the belt 3 caused by the sharp edges of the crushed stones directly contacting the belt 3. The buffer pads 613 can buffer and damp the vibration of the hollow seat 621, reducing the impact of the vibration on the hollow seat 611. During the vibration process, the driving part 626 (composed of components such as a motor and a reducer, used to drive the structure to rotate, which belongs to the commonly used prior art and will not be elaborated here) can also drive the two stirring rollers 627 to rotate. On the one hand, the rotation of the stirring rollers 627 can drive the crushed stones to move and cause contact between multiple crushed stones, and on the other hand, it can convey the crushed stones towards the direction of the discharge port 623, avoiding the situation of material accumulation inside the hollow seat 621.

[0046] As Figure 8 and Figure 9 shown, a wetting component 9 is further connected inside the hollow seat 611, and the wetting component 9 is located below the hollow seat 621. The wetting component 9 includes an inclined plate 91 fixedly connected to the inner wall of the hollow seat 611 and located below the discharge port 623, two limiting plates 92 fixedly connected to the upper end of the inclined plate 91, a cross plate 93 fixedly connected to the inner wall of the hollow seat 611, and multiple atomizing nozzles 99 fixedly connected to one side of the cross plate 93. The output ends of the multiple atomizing nozzles 99 all face the inclined plate 91.

[0047] The wetting component 9 further includes a second cross plate 94 fixedly connected to the inner wall of the first hollow seat 611, a plurality of connecting rods 95 fixedly connected to one side of the second cross plate 94, slots 96 formed in the left and right sides and the lower end of the plurality of connecting rods 95, a first atomizing nozzle 97 fixedly connected in the slots 96, and a plurality of liquid supply connectors 98 fixedly connected to the second cross plate 94 and respectively connected to the first atomizing nozzle 97 inside each connecting rod 95. The other end of the connecting rod 95 is fixedly connected to one side of the inclined plate 91.

[0048] By adopting the above technical solution, after the crushed stones inside the second hollow seat 621 are discharged from the discharge port 623, the crushed stones can fall on the inclined plate 91. When the crushed stones slide down on the inclined plate 91, the second atomizing nozzle 99 (which belongs to a mature prior art, its input end can be connected to a pump body through a pipeline, which is a conventional matching method in the prior art, so the pipeline and the pump body are not shown in this application and will not be elaborated here) sprays atomized water droplets to perform atomizing and wetting treatment on the crushed stones. When the crushed stones slide down from the inclined plate 91, they will first contact the plurality of connecting rods 95 or pass through the gaps between the plurality of connecting rods 95. The liquid supply connector 98 can be externally connected to a liquid supply pipe, and the liquid enters the first atomizing nozzle 97 through the liquid supply connector 98. The first atomizing nozzle 97 sprays atomized water droplets to wet the outer surface side of the crushed stones passing through the gaps between the plurality of connecting rods 95. The crushed stones passing through the gaps between the plurality of connecting rods 95 will fall on the support plate 71. After uniformly wetting the crushed stones, the moisture forms a thin film covering the surface of the crushed stones, affecting the mutual friction force between the crushed stones. When there is moisture on the surface of the crushed stones, the moisture will increase the resistance between the crushed stones and the air. Compared with the dry crushed stones, the wet crushed stones have a reduced sliding speed due to the increased friction with the air, which means that the acceleration of the crushed stones when sliding on the support plate 71 will be reduced, thereby reducing the impact force on the conveyor belt. Moreover, the moisture forms a lubricating effect between the crushed stone particles, reducing the friction force between the particles. When the crushed stones freely fall from a higher position, the wet surface can reduce the relative friction between the particles, making them slide more smoothly. At the same time, it can adsorb the tiny dust on the surface and between the particles of the crushed stones to prevent it from flying. Under the action of moisture, the dust particles on the surface of the crushed stones will adhere to the wet surface and are not easily carried away by the air, thereby reducing the risk of dust flying. This has a positive effect on improving the working environment and reducing air pollution.

[0049] Such as Figure 4 And Figure 10As shown, an air flow deceleration part 10 is further connected to the lower end of the hollow seat 611. The air flow deceleration part 10 includes two extension frames 101 symmetrically fixed to the lower end of the hollow seat 611, an adjustment seat 102 with both ends rotatably connected to one side of the two extension frames 101 respectively, a jet head 105 and a drainage cover 104 fixed to one side of the adjustment seat 102, and a second motor 103 fixed to one side of one of the extension frames 101. The output shaft of the second motor 103 penetrates through the extension frame 101 and is fixed to one side of the adjustment seat 102.

[0050] By adopting the above technical solution, the jet head 105 is a nozzle for ejecting air flow. Its input end can be externally connected to an air pipe. The gas in the air pipe enters the jet head 105 and is ejected from the jet head 105. The air flow can blow towards the crushed stones on the pallet 71. When the air flow passes through the gap between the pallet 71 and the crushed stones, the air flow will generate a buoyancy force on the crushed stones. This buoyancy force will partially offset the gravity of the crushed stones, thereby slowing down the falling speed of the crushed stones. When the second motor 103 works, it can drive the adjustment seat 102 and the jet head 105 to rotate. By adjusting the intensity and direction of the air flow, the falling speed of the crushed stones can be precisely controlled, so that the crushed stones will not fall too fast when falling on the pallet 71, reducing the impact force when contacting the conveyor belt.

[0051] Usage method: The crushed stones directly fall from above the hollow seat 611 into the hollow seat 621 located inside the hollow seat 611. After being distributed by the material distribution plate 628, the crushed stones respectively fall into both sides inside the hollow seat 621 and slide towards the discharge port 623 along the inclined surface 629. The vibration part 624 works to drive the hollow seat 621 to vibrate, causing the crushed stones inside the hollow seat 621 to vibrate, making the edges of the crushed stones blunt. The second driving part 626 drives the stirring roller 627 to rotate, conveying the crushed stones towards the discharge port 623. The crushed stones discharged from the discharge port 623 can fall on the inclined plate 91. The atomizing nozzle 99 ejects atomized water droplets to perform atomizing and wetting treatment on the crushed stones. When the crushed stones slide down from the inclined plate 91, they will first contact the multiple connecting rods 95 or pass through the gaps between the multiple connecting rods 95. The liquid supply joint 98 can be externally connected to a liquid supply pipe. The liquid enters the atomizing nozzle 97 through the liquid supply joint 98. The atomizing nozzle 97 ejects atomized water droplets to wet the outer surface side of the crushed stones passing through the gaps between the multiple connecting rods 95. The crushed stones passing through the gaps between the multiple connecting rods 95 will fall on the pallet 71. The air flow ejected by the jet head 105 can blow towards the crushed stones on the pallet 71, slowing down the falling speed of the crushed stones. The crushed stones first contact the surface of the pallet 71 before falling onto the belt 3. The pallet 71 can reduce the drop height of the crushed stones falling from a high place to a certain extent, reducing the kinetic energy of the material, so that it will not generate too large an impact when contacting the belt 3.

[0052] As described above, it is only the preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
