Description

Technical Field

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

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

[0003] In the prior art, the conveyor belt used for conveying gravel is usually composed of a support member and a transport belt arranged on the support member. For example, a gravel conveyor disclosed in the Chinese invention application patent with publication number CN111634612A and a gravel conveying device for mining disclosed in the Chinese invention patent with publication number CN107458820B both adopt this structure. Although the gravel conveyor belt composed of a support member and a transport belt arranged on the support member can realize the function of transporting gravel, the gravel usually has a large mass and a high falling speed. When they fall on the conveyor belt, they will generate a strong impact force. When the conveyor belt is subjected to a large impact, the surface material may be deformed, and the parts subjected to long-term impact will cause cracks, wear or tear. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present scheme is provided with a support buffer assembly, which can guide the crushed stone falling from a height through the support plate, so that the crushed stone contacts the surface of the support plate before falling onto the conveyor belt. The support plate can reduce the drop of the crushed stone falling from a height to a certain extent, reduce the kinetic energy of the material, and prevent it from generating 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 stone can be effectively controlled, reducing the impact force of the crushed stone on the conveyor belt. This can greatly reduce the impact force caused by the crushed stone falling directly onto the conveyor belt, reduce the wear and damage of the conveyor belt, and help extend the service life of the conveyor belt. In addition, if the edge of the crushed stone is very sharp, direct contact with the conveyor belt may scratch the surface of the conveyor belt, and this risk can be mitigated by the buffering of the support plate.

[0020] (2) The present solution is provided with an edge passivation component. The crushed stones can first fall into the hollow seat 2, and the vibrating part can drive the hollow seat 2 to vibrate. During the vibration process, when the crushed stones collide with each other, the edges and surfaces will experience continuous impact and friction. These forces can gradually remove the sharp parts of the surface of the crushed stones and smoothen the sharp edges, making them smoother or blunt. This process can optimize the shape of the crushed stones, reduce the sharp corners or irregularities of the crushed stones, and avoid the sharp edges of the crushed stones directly contacting the conveyor belt and causing damage to the conveyor belt.

[0021] (3) This scheme is provided with a wetting component, which can perform atomization wetting treatment on the gravel on the inclined plate through atomizing nozzle 2, and can perform wetting treatment on the outer surface of the falling gravel through atomizing nozzle 1. After the gravel is uniformly wetted, the water forms a thin film covering the surface of the gravel, affecting the mutual friction between the gravel. When there is water on the surface of the gravel, the water will increase the resistance between the gravel and the air. Compared with dry gravel, the sliding speed of wet gravel will decrease due to the increased friction with the air, which means that the acceleration of the gravel when falling will be reduced, thereby reducing its impact on the conveyor belt.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 11A gravel conveyor belt with a shock-absorbing structure comprises a support 1, a plurality of roller groups 2 fixed to one side of the support 1, two driving rollers 4 rotatably connected to the inside of the support 1, a belt 3 sleeved on the outside of the plurality of roller groups 2 and the two driving rollers 4, a driving part 5 fixed to one side of the support 1 for driving one of the driving rollers 4 to rotate, and also comprises a plurality of buffer seats 11 fixed to one side of the support 1 and located between the roller group 2 and the support 1; the plurality of roller groups 2 comprise roller frames 21 fixed to one side of the support 1, symmetrically rotating links 3, and a plurality of buffer seats 11 fixed to one side of the support 1 and located between the roller group 2 and the support 1; the plurality of roller groups 2 comprise roller frames 21 fixed to one side of the support 1, a belt 3 sleeved on the outside of the plurality of roller groups 2 and the two driving rollers 4, and a driving part 5 fixed to one side of the support 1 for driving one of the driving rollers 4 to rotate. Two side rollers 22 connected to the two sides of the roller frame 21, two movable grooves 23 symmetrically opened on the inner wall of the roller frame 21, two guide rods 25 respectively fixed to the inner walls of the two movable grooves 23, two springs 26 respectively sleeved on the outside of the two guide rods 25, two slide seats 24 respectively slidably connected in the two movable grooves 23 and movably sleeved on the outside of the guide rods 25, a middle roller 27 whose two ends are rotatably connected to one side of the two slide seats 24, and the two ends of the two springs 26 are respectively connected to the slide seat 24 and the inner wall of the movable groove 23.

[0037] The bracket 1 is also connected to a material buffer portion 6 on one side, and the material buffer portion 6 includes two support portions fixedly connected to one side of the bracket 1 and a feed portion 61 fixedly connected to one side of the two support portions;

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

[0039] The support portion includes two buffer seats three 66 symmetrically fixed to one side of the bracket 1, two support frames 65 respectively fixed to one side of the two buffer seats three 66, and two buffer seats two 64 respectively fixed to one side of the two support frames 65. The two buffer seats two 64 are symmetrically fixed to the lower end of the hollow seat one 611.

[0040] One side of the hollow seat 611 is symmetrically rotatably connected to two gears 1 76 and two gears 2 77 respectively meshing with the two gears 1 76. One side of the two gears 2 77 is fixedly connected to a synchronous wheel 78, and the two synchronous wheels 78 are connected through a synchronous belt 79. One side of the hollow seat 611 is also fixedly connected to a protective cover 8, and one side of the protective cover 8 is fixedly connected to a motor 1 81. The output shaft of the motor 81 passes through the protective cover 8 and is fixedly connected to one side of one of the synchronous wheels 78. One end of the two screw rods 73 passes through the hollow seat 611 and is respectively fixedly connected to the two gears 1 76.

[0041] By adopting the above technical solution, the crushed stone enters the hollow seat 1 611 from above the hollow seat 1 611, is discharged from the opening 63 at the bottom of the hollow seat 1 611 and falls on the support plate 71. The crushed stone first contacts the surface of the support plate 71 before falling onto the belt 3. The support plate 71 can reduce the drop of the crushed stone from a height to a certain extent, reduce the kinetic energy of the material, and prevent it from generating excessive impact when contacting the belt 3. The driving motor 1 81 can drive one of the synchronous wheels 78 to rotate, and the rotating synchronous wheel 78 drives the other synchronous wheel 78 to rotate through the synchronous belt 79. The two synchronous wheels 78 rotate to drive the two gears 2 77 to rotate, and the two gears 2 77 rotate to drive the two gears 1 76 and the two gears 1 77 to rotate. The screw rod 73 rotates, and when the screw rod 73 rotates, it can drive the wire seat 74 to move in the movable groove 2 72. The movement of the wire seat 74 can drive the support plate 71 to rotate in the movable groove 2 72 through the connecting rod 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 stone can be effectively controlled, and the impact force of the crushed stone on the belt 3 can be reduced. This can greatly reduce the impact force caused by the crushed stone falling directly on the belt 3, reduce the wear and damage of the belt 3, and help to extend the service life of the belt 3. Not only that, if the edge of the crushed stone is very sharp, direct contact with the belt 3 may scratch the surface of the conveyor belt, and this risk can be reduced through the buffering of the support plate 71.

[0042] like Figure 5-Figure 7 As shown, the feed part 61 also includes an edge passivation component 62 connected to the inside of the hollow seat 1 611, and the edge passivation component 62 includes a hollow seat 2 621 located inside the hollow seat 1 611, a material cavity 622 opened inside the hollow seat 2 621, two inclined surfaces 629 opened on the inner wall of the material cavity 622, a dividing plate 628 fixed on the inner wall of the material cavity 622, a discharge port 623 opened at the lower end of the hollow seat 2 621 and connected to the material cavity 622, and two vibration parts 624 symmetrically fixed to the lower end of the hollow seat 2 621, and the outside of the hollow seat 2 621 is connected to the inner wall of the hollow seat 1 611 through a buffer structure.

[0043] The buffer structure includes multiple groups of connecting seats 1 612 fixedly connected to the inner wall of the hollow seat 1 611, multiple connecting seats 2 625 fixedly connected to the outside of the hollow seat 2 621 and respectively connected to the multiple groups of connecting seats 1 612, and a buffer pad 613 arranged at the connection between the connecting seat 2 625 and the connecting seat 1 612.

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

[0045] By adopting the above technical solution, when the crushed stones fall into the hollow seat 1 611, they will directly fall into the hollow seat 2 621 located inside the hollow seat 1 611. After being divided by the dividing plate 628, the crushed stones fall into the two sides of the hollow seat 2 621 respectively, and slide from the inclined surface 629 toward the discharge port 623. When the crushed stones are inside the hollow seat 2 621, the vibrating part 624 (a vibration motor can be used, which belongs to the prior art and will not be described here) works to drive the hollow seat 2 621 to vibrate, so that the crushed stones inside the hollow seat 2 621 vibrate. During the vibration process, when the crushed stones collide with each other, the edges and surfaces will experience continuous impact and friction. These forces can gradually remove the sharp parts of the surface of the crushed stones, smooth the sharp edges, and thus become more The process of rounding or blunting can optimize the shape of the gravel, reduce the sharp corners or irregularities of the gravel, and avoid the sharp edges of the gravel directly contacting the belt 3 to cause damage to the belt 3. The buffer pad 613 can buffer and reduce the vibration of the hollow seat 2 621, and reduce the impact of the vibration on the hollow seat 1 611. During the vibration process, the driving part 2 626 (composed of components such as a motor and a reducer, used to drive the structure to rotate, which belongs to the commonly used existing technology and will not be repeated here) can also drive the two stirring rollers 627 to rotate. The rotation of the stirring roller 627 can, on the one hand, drive the gravel to move and make multiple gravel contact each other, and on the other hand, can transport the gravel to the direction of the discharge port 623, to avoid the accumulation of materials inside the hollow seat 2 621.

[0046] like Figure 8 and Fig. 9 As shown, the inside of the hollow seat 611 is also connected to a wetting component 9, 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 horizontal plate 93 fixedly connected to the inner wall of the hollow seat 611, and a plurality of atomizing nozzles 99 fixedly connected to one side of the horizontal plate 93, and the output ends of the plurality of atomizing nozzles 99 are all facing the inclined plate 91.

[0047] The wetting component 9 also includes a horizontal plate 94 fixedly connected to the inner wall of the hollow seat 611, a plurality of connecting rods 95 fixedly connected to one side of the horizontal plate 94, slots 96 opened on the left and right sides and the lower ends of the plurality of connecting rods 95, an atomizing nozzle 97 fixedly connected in the slot 96, a plurality of liquid supply connectors 98 fixedly connected to the horizontal plate 94 and respectively connected to the atomizing nozzle 97 inside each connecting rod 95, and 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 gravel inside the hollow seat 621 is discharged from the discharge port 623, the gravel can fall on the inclined plate 91. When the gravel slides down on the inclined plate 91, the atomizing nozzle 99 (which belongs to the mature existing technology, and its input end can be connected to the pump body through a pipeline, which belongs to the conventional matching mode in the existing technology. Therefore, the pipeline and the pump body are not shown in this application and are not repeated here) sprays atomized water droplets to perform atomization and wetting treatment on the gravel. When the gravel slides down the inclined plate 91, it will first contact with multiple connecting rods 95 or pass through the gaps between the multiple connecting rods 95. The liquid supply connector 98 can be externally connected to the liquid supply pipe. The liquid enters the atomizing nozzle 97 through the liquid supply connector 98, and the atomizing nozzle 97 sprays The atomized water droplets are used 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 support plate 71. After the crushed stones are evenly wetted, the water forms a thin film covering the surface of the crushed stones, affecting the mutual friction 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 wet crushed stones will have a lower 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 its impact on the conveyor belt, and the water forms a lubricating effect between the crushed stone particles, reducing the friction between the particles. When the crushed stones fall freely from a higher position, the wet surface can reduce the relative friction between the particles, making them slide more smoothly, and at the same time, it can absorb the tiny dust between the surface of the crushed stones and the particles to prevent them from flying. Under the action of moisture, the dust particles on the surface of the gravel will adhere to the wet surface and are not easily carried away by the air, thus reducing the risk of dust flying. This has a positive effect on improving the working environment and reducing air pollution.

[0049] like Figure 4 and Fig.10As shown, the lower end of the hollow seat 611 is also connected to an airflow deceleration part 10, and the airflow deceleration part 10 includes two extension frames 101 symmetrically fixed to the lower end of the hollow seat 611, an adjustment seat 102 whose two ends are rotatably connected to one side of the two extension frames 101, a nozzle 105 and a drainage cover 104 fixed to one side of the adjustment seat 102, and a motor 103 fixed to one side of one of the extension frames 101, and the output shaft of the motor 103 passes through the extension frame 101 and is fixed to one side of the adjustment seat 102.

[0050] By adopting the above technical solution, the nozzle 105 is a nozzle that ejects airflow, and its input end can be connected to an air pipe. After the gas in the air pipe enters the nozzle 105, it is ejected from the nozzle 105. The airflow can blow toward the gravel on the support plate 71. When the airflow passes through the gap between the support plate 71 and the gravel, the airflow will generate buoyancy on the gravel, and this buoyancy will partially offset the gravity of the gravel, thereby slowing down the falling speed of the gravel. The operation of the motor 2 103 can drive the adjustment seat 102 and the nozzle 105 to rotate. By adjusting the intensity and direction of the airflow, the descending speed of the gravel can be accurately controlled, so that the gravel will not fall too fast on the support plate 71, reducing the impact force when it contacts the conveyor belt.

[0051] Method of use: The crushed stones fall directly from the top of the hollow seat 1 611 into the hollow seat 2 621 located inside the hollow seat 1 611. The crushed stones fall into the two sides of the hollow seat 2 621 after being divided by the dividing plate 628, and slide from the inclined surface 629 toward the discharge port 623. The vibration part 624 drives the hollow seat 2 621 to vibrate, so that the crushed stones inside the hollow seat 2 621 vibrate, and the edges of the crushed stones are blunted. The driving part 2 626 drives the stirring roller 627 to rotate, and transports the crushed stones toward the discharge port 623. The crushed stones discharged from the discharge port 623 can fall on the inclined plate 91. The atomizing nozzle 2 99 sprays atomized water droplets to atomize and wet the crushed stones. When the crushed stones slide down the inclined plate 91, they will first contact with multiple connected The rod 95 contacts or passes through the gaps between the multiple connecting rods 95. The liquid supply connector 98 can be externally connected to a liquid supply pipe. The liquid enters the atomizing nozzle 97 through the liquid supply connector 98. The atomizing nozzle 97 sprays atomized water droplets to wet the outer surface side edges 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 support plate 71. The airflow sprayed by the nozzle 105 can blow to the crushed stones on the support plate 71 to slow down the falling speed of the crushed stones. The crushed stones first contact the surface of the support plate 71 before falling onto the belt 3. The support plate 71 can reduce the drop of the crushed stones from a high place to a certain extent, reduce the kinetic energy of the materials, and prevent them from generating excessive impact when contacting the belt 3.

[0052] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
