Description

Technical Field

[0001] The present invention relates to the technical field of crusher feeders, and particularly to an efficient feeding mechanism for a crusher used in mines. Background Art

[0002] A crusher is a crushing machine that crushes the mined raw ore into small particles through extrusion and bending actions, etc. Also known as a stone crusher, it is a device used in the processing of metal and non-metal ores. Since the amount of ore crushing is large, in order to meet the continuous operation of the crusher, it is necessary to cooperate with a feeder to continuously and evenly convey the ore to the crusher.

[0003] A feeder, also known as a feeding machine, is an important part of a crushing production line. Its main function is to evenly and continuously convey lumpy and granular materials from a storage bin or other sources into the crusher to ensure that the crusher can work continuously and stably.

[0004] In the existing feeder mechanism, the feeding port is usually fixedly set, making it difficult to adapt to ore raw materials of different particle sizes. It is impossible to scale the opening according to the size of the ore type to adjust the conveying speed, resulting in low adaptability. At the same time, when the feeder continuously conveys ore raw materials to the crusher, the feeding port of the feeder is prone to having too many scratches and dust due to long-term friction with the ore, lacking lubrication, which will directly affect the smoothness of the ore, and there will be a large resistance during transportation. Moreover, the feeding port continuously rubs against the ore, leading to increased wear, shortening the service life of the equipment, and it is difficult to screen ore materials of different sizes, easily causing the phenomenon of small materials protecting large materials, which are difficult to be crushed in the crusher, increasing the crushing load. Therefore, the present application provides an efficient feeding mechanism for a crusher used in mines to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an efficient feeding mechanism for a crusher used in mines to solve the problems of the existing feeder mechanism, which is difficult to adapt to ore raw materials of different particle sizes for scaling the opening to adjust the conveying speed. At the same time, the feeder lacks lubrication, directly affecting the smoothness of the ore, having a large resistance during transportation, and the feeding port continuously rubs, resulting in increased wear, shortening the service life of the equipment, and it is difficult to screen ore materials of different sizes, easily causing the problem of small materials protecting large materials.

[0012] Optionally, a liquid guide pipe is installed at the bottom of the oil chamber, one end of the liquid guide pipe is equipped with a sleeve, and an inner pipe is slidably connected inside the sleeve. The bottom of the inner pipe is provided with small holes.

[0013] Optionally, a second spring is sleeved on the surface of the inner pipe, a resistance chamber is installed inside the inner pipe, a honeycomb plate is installed inside the resistance chamber, and a fixing plate is installed on the top of the resistance chamber.

[0014] Optionally, the jitter screening component includes a recycling bin, which is installed at one end of the operation chamber. A vibration plate is installed on the inner wall of the operation chamber, and a material guiding bin is arranged below the vibration plate.

[0015] Optionally, a housing is installed inside the vibration plate. A rotating head is installed at one end of the operation chamber. One end of the rotating head is threadedly connected to a second threaded column, and a push rod is installed at one end of the second threaded column.

[0016] Optionally, a push tube is inserted on the surface of the push rod. One end of the push tube is installed with a slider, a conical plate is installed on the top of the slider, and the bottom of the slider is slidably connected to a chute frame.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above solution, by setting the opening adjusting component, the feed inlet of the feeding mechanism can easily adapt to ores of different types and sizes, ensuring that the feeder can effectively feed ores into the crusher regardless of their hardness, shape or size, reducing the downtime for adjustment caused by changes in ore types, improving production efficiency. At the same time, the adjustable feed inlet can adjust the conveying speed of the material according to the actual demand and the size of the material, ensuring that the crusher is always in the best working state, reducing energy consumption. And the adjustable opening helps to protect the feeding mechanism from damage caused by oversized or irregular ores. By precisely controlling the size of the opening, the quality of the ores is ensured, thus avoiding blockage and wear and causing damage to the equipment.

[0019] By setting the lubricating spraying component, lubricating liquid is sprayed on the feed inlet of the feeding mechanism to reduce the frictional resistance of the material when passing through the feed inlet, enabling the material to enter more smoothly, avoiding material blockage or jamming caused by excessive friction. This not only improves the conveying speed of the feeder but also reduces the downtime caused by blockage. At the same time, the spraying of the lubricating liquid can reduce the wear degree of the feed inlet and surrounding components, extend the service life of the feeder and surrounding components, reduce maintenance costs, and the lubricating liquid can also play a certain cooling role to prevent damage to the equipment caused by heat generated by friction and extend the service life of the equipment.

[0020] By setting up a jitter screening component, the ore materials entering the feeding mechanism are screened, and the ore materials that do not meet the crushing size are effectively separated, ensuring that only the ore materials meeting the requirements enter the crusher, avoiding equipment wear and blockage caused by too small ore material size. And when the ore materials enter the crusher, through jitter screening, the ore materials that do not meet the size requirements can be reduced, and precise screening can be carried out to ensure that the ore materials entering the crusher have uniform sizes, reduce the entry of smaller particles, avoid the occurrence of the phenomenon of small materials protecting large materials, improve the crushing quality, reduce the crushing load, and the ore materials that do not meet the current crushing requirements collected can be used for other purposes, improving the utilization rate of the ore.

According to specific needs, those of ordinary skill in the art can adjust or modify these devices and environments. Detailed implementation manners

[0036] The following will describe in detail a high-efficiency feeding mechanism for a mine crusher provided by the present invention with reference to the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0037] It should be noted that in the specification, references to "one embodiment", "embodiment", "exemplary embodiment", "some embodiments", etc. indicate that the described embodiments may include specific features, structures, or characteristics, but not necessarily every embodiment includes such specific features, structures, or characteristics. Additionally, when combining embodiments to describe specific features, structures, or characteristics, implementing such features, structures, or characteristics in combination with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the relevant art.

[0038] As Figures 1 to 11As shown in the figure, an embodiment of the present invention provides an efficient feeding mechanism for a crusher used in a mine, which includes a frame 1. An operation chamber 2 is installed at the top of the frame 1. A conveyor belt 4 is also installed at the top of the frame 1. A crusher 3 is arranged in front of the frame 1. A baffle 5 is installed at one end of the operation chamber 2. A vibration motor 10 is installed at one end of the operation chamber 2. A pressure roller 9 is installed inside the operation chamber 2; an opening adjustment assembly 6, which is installed at the top end of the operation chamber 2 and is used to adjust the opening size of the feeding port of the operation chamber 2; a lubrication spraying assembly 7, which is installed on the inner wall of the operation chamber 2 and is used to lubricate the opening adjustment assembly 6; a vibrating screening assembly 8, which is installed at one end of the operation chamber 2 and is used to screen the ore; the opening adjustment assembly 6 is installed at one end of the lubrication spraying assembly 7, and the lubrication spraying assembly 7 is installed above the vibrating screening assembly 8.

[0039] As an implementation manner in this embodiment, as Figures 4 to 7As shown, the opening adjustment assembly 6 includes a sleeve 61. The surface of the sleeve 61 is rotatably connected to the inner wall of the operation chamber 2. One end of the sleeve 61 is provided with a disc 62. One end of the disc 62 is rotatably connected to a round shaft 63. One end of the round shaft 63 is rotatably connected to a connecting rod 64. The top of the connecting rod 64 is rotatably connected to a connecting arm 65. One end of the connecting arm 65 is provided with an opening and closing plate 67. There are two groups of opening and closing plates 67, which are symmetrical about the axis of the disc 62 and are distributed on both sides of the connecting rod 64. One end of the connecting arm 65 is rotatably connected to a fixed rotating shaft 66. The fixed rotating shaft 66 passes through the connecting arm 65. One end of the sleeve 61 is provided with a first threaded column 68. One end of the first threaded column 68 is provided with a turntable 69. The first threaded column 68 is fixedly connected to one end of the turntable 69. After the type and size of the ore are determined, the opening adjustment assembly 6 inside the operation chamber 2 is adjusted. By the worker rotating the turntable 69 provided at one end of the operation chamber 2, according to the size of the ore, the turntable 69 is rotated. When the turntable 69 rotates, the first threaded column 68 installed at one end of the turntable 69 rotates synchronously. When the first threaded column 68 rotates, the sleeve 61 installed on the surface of the first threaded column 68 rotates together. When the sleeve 61 rotates, the disc 62 installed at one end of the sleeve 61 starts to rotate together with the sleeve 61. When the disc 62 rotates, the disc 62 drives the round shaft 63 installed at one end to move together. When the round shaft 63 moves in the rotation direction of the disc 62, the round shaft 63 drives the connecting rod 64 rotatably connected at one end to move. The movement of the connecting rod 64 drives the connecting arm 65 installed at the top of the connecting rod 64 to rotate. At this time, the connecting arm 65 is subjected to the pulling force of the connecting rod 64 and starts to move in the moving direction of the connecting rod 64. At this time, while the connecting arm 65 follows the movement of the connecting rod 64, under the action of the fixed rotating shaft 66, the connecting arm 65 can only rotate around the fixed rotating shaft 66. When the connecting arm 65 rotates around the fixed rotating shaft 66, one end of the connecting arm 65 tilts up. At this time, the opening and closing plate 67 installed at one end of the connecting arm 65 flips. When the connecting arm 65 flips, the two groups of symmetrical opening and closing plates 67 flip synchronously. At this time, the flipping angle of the opening and closing plate 67 is controlled by the turntable 69. The opening between the two groups of opening and closing plates 67.

[0040] As an implementation method in this embodiment, as Figures 5 to 8As shown, the lubricating spraying assembly 7 includes an oil cavity 71. The oil cavity 71 is installed on the inner wall of the operation cavity 2. A pressing rod 72 is installed at the top of the oil cavity 71. The bottom of the pressing rod 72 is slidably connected to the inner wall of the oil cavity 71 and is installed inside the oil cavity 71. A first spring 73 is sleeved on the surface of the pressing rod 72. The first spring 73 is arranged between the bottom of the pressing rod 72 and the top of the oil cavity. A liquid guide pipe 74 is installed at the bottom of the oil cavity 71. One end of the liquid guide pipe 74 is installed with a sleeve 75. An inner pipe 76 is slidably connected inside the sleeve 75. The bottom of the inner pipe 76 is provided with small holes. A second spring 77 is sleeved on the surface of the inner pipe 76. A resistance chamber 78 is installed inside the inner pipe 76. A honeycomb plate 79 is installed inside the resistance chamber 78. A fixing plate 710 is installed at the top of the resistance chamber 78. When the connecting rod 64 rotates following the disc 62, the lubricating spraying assembly 7 is squeezed by the connecting rod 64 and starts to operate. When the connecting rod 64 flips, the pressing rod 72 is squeezed by one end of the connecting rod 64 and starts to move downward. When the pressing rod 72 moves downward, the first spring 73 sleeved on the surface of the pressing rod 72 starts to contract. At the same time, the downward movement of the pressing rod 72 causes the lubricating oil inside the oil cavity 71 to be input into the inside of the sleeve 75 through the liquid guide pipe 74. When the oil in the oil cavity 71 enters the inside of the sleeve 75, it starts to impact upward and push the inner pipe 76 upward. When the inner pipe 76 is pushed up, the second spring 77 sleeved on the surface of the inner pipe 76 is between the sleeve 75 and the inner pipe 76 and is squeezed and contracts. The oil continues to move upward through the small opening at the bottom of the inner pipe 76, passes through the resistance chamber 78 and then through the honeycomb plate 79, and then passes through the fixing plate 710 and is sprayed out through the opening at the top of the inner pipe 76. When the lubricating liquid spraying is completed, it is stretched through the elasticity of the second spring 77. When the second spring 77 resets, the inner pipe 76 starts to contract into the inside of the sleeve 75 until it completely enters the inside of the sleeve 75, protecting the nozzle at the top of the inner pipe 76 from being contaminated.

[0041] As an implementation method in this embodiment, as Figures 9 to 11As shown in the figure, the jitter screening component 8 includes a recycling bin 81, which is installed at one end of the operation chamber 2. A vibration plate 83 is installed on the inner wall of the operation chamber 2. A material guiding bin 82 is arranged below the vibration plate 83. A housing 84 is installed inside the vibration plate 83. A rotating head 85 is installed at one end of the operation chamber 2. One end of the rotating head 85 is threadedly connected to a second threaded column 86. One end of the second threaded column 86 is installed with a push rod 87. A push tube 88 is inserted on the surface of the push rod 87. One end of the push tube 88 is installed with a slider 89. A conical plate 810 is installed on the top of the slider 89. The bottom of the slider 89 is slidably connected to a chute frame 811. When the vibration motor 10 is started, the jitter screening component 8 is adjusted. The rotating head 85 rotatably connected to one end of the operation chamber 2 is rotated. When the rotating head 85 rotates, the second threaded column 86 threadedly connected inside the rotating head 85 moves. When the second threaded column 86 moves, the push rod 87 installed at one end of the second threaded column 86 is pushed to move. At this time, the movement of the push rod 87 drives the push tube 88 installed on the surface of the push rod 87 to move together. The movement of the push tube 88 drives the slider 89 installed at one end of the push tube 88 to start moving. At this time, the slider 89 starts to slide inside the chute frame 811. When the slider 89 slides, the conical plate 810 installed on the top of the slider 89 starts to move. At this time, the conical plate 810 opens inside the housing 84 according to the rotation force of the rotating head 85 to adjust the distance between multiple conical plates 810, so as to screen out small ore materials that do not meet the crushing conditions. At this time, the supply of ore materials starts. The ore materials enter through the opening of the operation chamber 2 and then pass through the surface of the vibration plate 83. At this time, the opening angle of the conical plate 810 filters out relatively small ore materials. The smaller ore materials fall into the material guiding bin 82 through the openings between the conical plates 810 and are continuously collected into the recycling bin 81 through the material guiding bin 82. Then the suitable ore materials pass through the vibration plate 83 and are transported to the conveyor belt 4, and then the conveyor belt 4 transports the ore materials into the crusher 3 for crushing.

[0042] The working principle of the technical solution provided by the present invention is as follows:

[0043] When using this device, first check whether all components of the crusher 3 and the feeding structure are in good condition to ensure the stability of the frame 1. Then check whether there are impurities in the operation chamber 2, whether there are foreign objects on the conveyor belt 4, and whether the enclosure 5 is cracked. Then adjust the height of the pressure roller 9 according to the type and size specifications of the ore. At the same time, add lubricating oil to the lubricating spraying component 7, and then set the opening size under the current ore material specifications by the opening adjusting component 6.

[0044] After the type and size of the mineral materials are determined, start to adjust the opening adjustment component 6 inside the operation chamber 2. By the worker rotating the turntable 69 provided at one end of the operation chamber 2, according to the size of the mineral materials, start to rotate the turntable 69. When the turntable 69 rotates, the first threaded column 68 installed at one end of the turntable 69 rotates synchronously. When the first threaded column 68 rotates, the sleeve 61 installed on the surface of the first threaded column 68 rotates together. When the sleeve 61 rotates, the disc 62 installed at one end of the sleeve 61 starts to rotate together with the sleeve 61. When the disc 62 rotates, the disc 62 drives the round shaft 63 installed at one end to move together. When the round shaft 63 moves in the rotation direction of the disc 62, the round shaft 63 drives the connecting rod 64 rotatably connected at one end to move. The movement of the connecting rod 64 drives the connecting arm 65 installed at the top of the connecting rod 64 to rotate. At this time, the connecting arm 65 is subjected to the pulling force of the connecting rod 64 and starts to move in the moving direction of the connecting rod 64. At this time, while the connecting arm 65 follows the movement of the connecting rod 64, under the action of the fixed rotating shaft 66, the connecting arm 65 can only rotate around the fixed rotating shaft 66. When the connecting arm 65 rotates around the fixed rotating shaft 66, one end of the connecting arm 65 warps up. At this time, the opening and closing plate 67 installed at one end of the connecting arm 65 flips. When the connecting arm 65 flips, the two symmetric opening and closing plates 67 flip synchronously. At this time, the flipping angle of the opening and closing plate 67 is controlled by the turntable 69. The opening between the two opening and closing plates 67 is the opening opened according to the current size of the mineral materials. At the same time, when the connecting rod 64 flips, the lubricating spraying component 7 starts to operate.

[0045] When the connecting rod 64 rotates following the disc 62, the lubricating spraying assembly 7 starts to operate under the extrusion of the connecting rod 64. When the connecting rod 64 flips, the pressing rod 72 is extruded by one end of the connecting rod 64 and starts to move downward. When the pressing rod 72 moves downward, the first spring 73 sleeved on the surface of the pressing rod 72 starts to contract. At the same time, the downward movement of the pressing rod 72 causes the lubricating oil in the oil cavity 71 to be input into the inside of the sleeve 75 through the liquid guide pipe 74. When the oil in the oil cavity 71 enters the inside of the sleeve 75, it starts to impact upward and push the inner pipe 76 upward. When the inner pipe 76 is pushed up, the second spring 77 sleeved on the surface of the inner pipe 76 is between the sleeve 75 and the inner pipe 76 and is squeezed to contract. The oil continues to move upward through the small opening at the bottom of the inner pipe 76, passes through the resistance chamber 78, then passes through the honeycomb plate 79, and then passes through the fixed plate 710 and is sprayed out through the opening at the top of the inner pipe 76. When the lubricating liquid spraying is completed, it stretches through the elasticity of the second spring 77. When the second spring 77 resets, the inner pipe 76 starts to contract into the inside of the sleeve 75 until it completely enters the inside of the sleeve 75, protecting the nozzle at the top of the inner pipe 76 from being contaminated. Then, start the machine and start feeding the ore into the feeding mechanism. Then start the vibration motor 10. When the vibration motor 10 starts, the vibrating screening assembly 8 starts to operate.

[0046] Before the vibration motor 10 starts, start to adjust the vibrating screening assembly 8. Rotate the rotating head 85 rotatably connected to one end of the operation cavity 2. When the rotating head 85 rotates, the second threaded column 86 threadedly connected inside the rotating head 85 moves. When the second threaded column 86 moves, the push rod 87 installed at one end of the second threaded column 86 is pushed to move. At this time, the movement of the push rod 87 drives the push tube 88 installed on the surface of the push rod 87 to move together. The movement of the push tube 88 drives the slider 89 installed at one end of the push tube 88 to start moving. At this time, the slider 89 starts to slide inside the chute frame 811. When the slider 89 slides, the cone plate 810 installed on the top of the slider 89 starts to move. At this time, the cone plate 810 opens inside the housing 84 according to the rotation force of the rotating head 85 to adjust the distance between multiple cone plates 810, so as to screen out small ore materials that do not meet the crushing conditions. At this time, start the supply of ore materials. The ore materials enter through the opening of the operation cavity 2 and then pass through the surface of the vibration plate 83. At this time, the opening angle of the cone plate 810 filters out relatively small ore materials, and the smaller ore materials fall into the guide bin 82 through the opening between the cone plates 810 and are continuously collected into the recycling bin 81 through the guide bin 82. Then the suitable ore materials pass through the vibration plate 83 and are conveyed to the conveyor belt 4, and then the conveyor belt 4 conveys the ore materials into the crusher 3 for crushing.
