Description

Technical Field

[0001] The invention belongs to the technical field of mineral production and processing, and in particular relates to a vibrating feeding device of an X-ray separator. Background Art

[0002] X-ray sorting machines are generally used in the coal field. X-ray sorting machines use X-ray transmission recognition technology and visual recognition technology to identify mineral materials. X-ray transmission recognition technology measures the X-ray energy penetrating the object to be identified through dual-source recognition of X-ray + CCD imaging technology based on the inconsistent absorption rate of radiation by different substances, with an accuracy rate of over 99%; visual recognition technology continuously scans the conveyor belt with a 3D camera to measure the shape and volume of the object in real time, and then scans the object to be measured with a high-resolution line scan camera to automatically generate a high-definition picture of the object. Finally, the intelligent algorithm module is used to deeply learn the material characteristics, accurately extract the material characteristics, and establish an analysis and prediction model, thereby improving the accuracy of material identification.

[0003] In actual use, the screened mineral raw materials are conveyed to the belt in the X-ray sorting machine cavity through the feeding system. The feeding system generally pours the mineral materials onto the belt in an inclined conveying manner. This method is very easy to cause the accumulation of mineral materials on the belt in actual operation. If the mineral materials are close to each other or even stacked together, it is very easy to cause inaccurate subsequent screening and identification problems. Secondly, if they are stacked together, it is also easy to cause inaccurate spraying execution during the subsequent mineral screening; secondly, when the mineral materials in the prior art are poured onto the belt through the feeding system, it is also easy to generate a large amount of dust. Although the prior art generally sets a dust removal system in the X-ray sorting machine cavity, the dust removal is also carried out after the dust occurs, which will also cause a large amount of dust in the X-ray sorting machine cavity and even affect the subsequent sorting operations.

[0012] As a preferred embodiment of the present invention, the lengths of the plurality of groups of discharge pipes are different in size, and there is a length difference between two adjacent discharge pipes.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This technical solution utilizes a feeding device, a feeding device, a dispersing device, and a discharging assembly. The feeding device can achieve quantitative addition of ore, preventing large amounts of ore from falling onto the belt and causing ore accumulation, which affects subsequent sorting efficiency. The feeding device can disperse the ore after unloading and then rotate it for feeding. Combined with a negative pressure vacuum cleaner, it can effectively reduce dust generation. The dispersing device can randomly disperse the ore after dust removal, and the discharging assembly can then disperse the dispersed ore onto the belt in a staggered manner, effectively avoiding ore accumulation and achieving orderly dispersion, which can improve subsequent sorting efficiency.

[0014] 2. This technical solution uses the dust removal pipe, suction cylinder and suction hole to set up. When the ore falls vertically into the feeding box cavity, a large amount of dust will be generated. The negative pressure vacuum cleaner performs negative pressure suction on the feeding box cavity through the first exhaust pipe and the dust removal pipe to suck away the generated dust, thereby achieving the first dust removal of the ore. When the ore enters the feeding purification bin, the rotation of the dispersion cylinder can make the ore in the feeding purification bin rotate and roll, accelerating the separation and dispersion of the dust on the ore. The dust generated in each feeding purification bin is sucked away by the suction. The holes are sucked away by negative pressure, thereby realizing secondary dust removal of the mineral material. Through two dust removals, the dust on the mineral material is effectively removed. When the dust-removed mineral material falls onto the belt, the problem of dust in the cavity of the sorting machine body can be reduced. By reducing the problem of dust in the cavity of the sorting machine body, not only the recognition efficiency of the depth camera and line scan camera can be improved, and the problem of their line of sight being blocked by dust can be avoided; and after the dust on the mineral material is removed, the recognition efficiency of the depth camera and line scan camera for the mineral material can be improved. This technical solution improves the sorting efficiency of the mineral material as a whole.

[0015] 3. This technical solution uses the conveyor belt, active rod, second driven rod, third driven rod and first driven rod provided, and the mineral material is located in the V-groove of the conveyor belt. When the active rod rotates, the active rod drives the conveyor belt to move, so that the mineral material in the V-groove of the conveyor belt moves continuously. In conjunction with the rotation of the dispersion barrel, the mineral material can tumble in each feeding purification bin. The conveyor belt in motion can perform a certain wiping action on the mineral material. Secondly, the conveyor belt in motion can make the mineral material move, so that the mineral material rubs against each other. In conjunction with the rotation of the dispersion barrel, the rolling and friction between the mineral materials can be accelerated, thereby improving the dispersion efficiency of the dust on the mineral material, thereby improving the efficiency of the dust collection work.

[0016] 4. This technical solution is controlled by the bulk material channel, the first cylinder, the second cylinder, the sealing plate and the pressure sensor. After the pressure sensor generates a signal, the corresponding discharge port is opened through the control system. When the first cylinder works again, it will slowly push the push plate forward. At this time, the mineral material in the bulk material channel is in the process of being pushed for discharge first, so that a time difference is generated between the bulk material channel and other bulk material channels. By generating a time difference in discharge, the mineral material in all the bulk material channels is prevented from being pushed together for discharge. This can reduce the probability of accumulation of the mineral material after discharge, and can effectively ensure the dispersion of the mineral material for the efficiency of subsequent sorting.

[0017] 5. This technical solution is based on the set discharge pipe, the third servo motor, the drive rod and the eccentric wheel. When the ore is pushed into the discharge pipe, the eccentric wheel intermittently lifts and shakes the individual discharge pipe, which not only accelerates the discharge of the ore, but also avoids the problem of easy blockage of the ore when there is a lot of ore; secondly, through the continuous slight swinging action of the discharge pipe, when the ore is discharged through the discharge pipe, the problem of the distance between two adjacent ore materials falling on the belt after discharge is too close can be avoided. Because the slight swing of the discharge end of the discharge pipe may cause one of the ore materials to swing slightly to the other side, and the next ore material may be thrown to the other side or fall directly through the discharge pipe. Therefore, when this situation occurs, the distance between the two adjacent ore materials can be slightly increased, thereby avoiding the accumulation of ore materials, thereby improving the subsequent sorting efficiency.

[0018] 6. This technical solution sets the discharge pipes to different lengths, and sets a certain length difference between two adjacent discharge pipes. This setting is to allow the ore to be discharged onto the belt in a staggered manner, and the ore is transported by the previous time difference. Then, through the staggered discharge, the position of the ore on the belt is in a certain order. After being guided by each discharge pipe, the ore will fall through the discharge pipe to the corresponding belt surface. There is a certain distance between the two adjacent discharge pipes, so the ore falling on the belt will also have a similar distance. In this way, the ore is dispersed on the belt in a certain order as much as possible, avoiding the accumulation of ore, causing inaccurate subsequent sorting, and improving the sorting efficiency of the ore.

The following embodiments are used to illustrate the present invention.

[0023] A vibrating feeding device for an X-ray sorting machine, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, it includes a sorting machine body 10, a feeding channel is opened on the upper side wall of the sorting machine body 10, a feeding pipe 11 is fixedly installed in the feeding channel, and the feeding pipe 11 is inclined toward the cavity of the sorting machine body 10. A belt is installed below the cavity of the sorting machine body 10, and the feeding pipe 11 is located at the bottom of one side of the cavity of the sorting machine body 10 and is fixedly connected to a downward first feeding pipe 12. A feeding device for quantitative feeding is provided below the first feeding pipe 12, and the feeding device includes a feeding box 20. The first feeding pipe 12 is vertically aligned with the feeding box 20 up and down, and a feeding device for rotary feeding and dust removal of mineral materials is provided below the feeding box 20. The material device includes a dispersion cylinder 30, on which a plurality of second material pipes 36 are fixedly installed. The dispersion cylinder 30 rotates to drive the second material pipes 36 to correspond to the output end position of the feeding box 20. A dispersion device for dispersing and conveying the mineral material to the belt is provided below the dispersion cylinder 30. The dispersion device includes a bottom plate 50. A plurality of equally spaced dividing plates 56 are provided on the bottom plate 50. The mineral material falls into the adjacent dividing plates 56 for dispersion and conveying. A discharge assembly for vibrating the dispersed material is also provided on one side of the bottom plate 50. The discharge assembly includes a plurality of discharge pipes 67. The dispersed material vibrates through the discharge pipes 67 and falls down onto the belt.

[0024] An X-ray sorting system is provided in the sorting body 10, and the X-ray sorting system includes a feeding system, an identification system, a rejection system, an air source system, a dust removal system, a control system, and a remote management system. The identification system includes a depth camera, a line scan camera, an X-ray source, an X-ray detector, etc. provided in the sorting body 10. The ore is conveyed on the belt. After the ore passes through the depth camera, the line scan camera, the X-ray source, and the X-ray detector at a uniform speed, the data is collected by the identification system, and is identified through density and neural network algorithms. The position and judgment information are given, and the rejection system and the air source system are notified to separate the materials. The above-mentioned X-ray sorting system, feeding system, identification system, rejection system, air source system, dust removal system, control system, remote management system, depth camera, line scan camera, X-ray source, X-ray detector, etc. are all existing technologies and are not repeated here. The model of the sorting body 10 is the SN-XRT1200 X-ray intelligent sorting machine.

[0025] During use, the outer end of the feed pipe 11 is connected to an external feeder, and the mineral material is transported into the feed pipe 11 after passing through the feeder, and the mineral material slides down along the inclined inner wall of the feed pipe 11, and is finally discharged into the cavity of the feeding box 20 through the first material pipe 12, and is weighed in the feeding box 20. After reaching a certain amount of mineral material, it is discharged into the second material pipe 36, and the mineral material enters the dispersion cylinder 30 through the second material pipe 36, and is rotated and transported in the dispersion cylinder 30. When the second material pipe 36 rotates to align with the discharge assembly, it is discharged into the discharge assembly, and finally discharged to the belt through multiple groups of discharge pipes 67, and is transported in a staggered distribution on the belt. This can avoid large-scale accumulation of mineral material and improve the sorting efficiency of the sorting machine 10. At the same time, by distributing the mineral material in a staggered manner on the belt, blockage during mineral material discharge can also be avoided, thereby improving the overall quality of mineral material discharge.

[0026] like Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 As shown, a connecting frame 14 is fixedly installed on one side wall of the cavity of the sorting machine body 10, and a connecting plate 15 is fixedly connected to the end of the connecting frame 14 close to the first material pipe 12. The first material pipe 12 is trumpet-shaped, and the bottom of the first material pipe 12 is cylindrical. A first butterfly valve 13 is installed on the inner wall of the cylindrical bottom of the first material pipe 12. The cylindrical bottom end of the first material pipe 12 extends into the feeding box 20, and a sealing bellows is also provided between the outer wall of the cylindrical bottom of the first material pipe 12 and the upper inner wall of the cavity of the feeding box 20; a limiting groove 17 is provided on the side wall of the connecting plate 15 close to the feeding box 20, and a limiting plate 16 is movably installed in the vertical direction in the limiting groove 17. The limiting plate 1 6 and the feeding box 20. A fixing plate 19 is fixedly installed between the limiting plate 16 and the feeding box 20. A weighing sensor 18 is installed on the bottom wall of the limiting plate 16 located in the cavity of the limiting groove 17. A plurality of dust removal pipes 21 are fixed on the outer wall of the feeding box 20. A through hole is provided on the wall of the feeding box 20 where the dust removal pipes 21 are connected to the feeding box 20. A first exhaust pipe 26 is fixedly connected to the outer wall of the dust removal pipe 21, and the first exhaust pipe 26 is connected to a negative pressure vacuum cleaner; a second butterfly valve 23 is installed on the inner wall of the bottom of the cavity of the feeding box 20, and a first mounting plate 24 is fixedly installed on the lower outer wall of the feeding box 20. An inductive proximity switch 25 facing vertically downward is fixedly installed on the bottom of the first mounting plate 24.

[0027] During use, when the mineral material is discharged into the cavity of the feeding box 20 through the feed pipe 11 and the first material pipe 12, the second butterfly valve 23 is in a closed state at this time, and the mineral material falls into the feeding box 20. As the mineral material in the feeding box 20 is added, when the set amount of mineral material is reached, the weighing sensor 18 completes the weighing. A control system is also provided in the sorting machine body 10. The weighing sensor 18 sends the model to the control system. The control system controls the first butterfly valve 13 to close, and then the second butterfly valve 23 to open. The second butterfly valve 23 opens first, and then the third butterfly valve 38 in the second material pipe 36 corresponding to the position of the second butterfly valve 23 opens. The mineral material is discharged into the second material pipe 36 through the feeding box 20, and finally enters the dispersion cylinder 30.

[0028] When the mineral material is discharged into the feeding box 20 through the first material pipe 12, the falling mineral material may generate dust. The control system controls the operation of the negative pressure vacuum cleaner. The negative pressure vacuum cleaner performs negative pressure suction on the cavity of the feeding box 20 through the first exhaust pipe 26 and the dust removal pipe 21 to suck away the generated dust. The dust enters the negative pressure vacuum cleaner and is then filtered. By setting a sealing bellows, the problem of a large amount of dust entering the cavity of the sorting body 10 can be avoided, and the sealing bellows has a certain degree of elasticity and can move up and down to a certain extent with the feeding box 20.

[0029] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12As shown, the second material pipe 36 is trumpet-shaped, and the end of the second material pipe 36 away from the dispersion cylinder 30 is cylindrical, and a third butterfly valve 38 is installed on the inner wall of the cylinder of the second material pipe 36; the dispersion cylinder 30 is a hollow cylinder, and side plates 31 are rotatably installed on the outer walls of both ends of the dispersion cylinder 30, and multiple groups of connecting frames 32 are fixedly installed on the outer walls of the two side plates 31, and the connecting frames 32 are fixedly connected to the wall surface of the cavity of the sorting machine body 10 through flanges; a suction cylinder 39 is fixedly installed at the center position of the cavity of the dispersion cylinder 30, and multiple groups of partitions 41 are fixedly installed between the outer wall of the suction cylinder 39 and the inner wall of the dispersion cylinder 30, and a material purification bin is formed between two adjacent partitions 41, and the second material pipe 36 corresponds to the position of each material purification bin, and the suction cylinder 39 is located at each material purification bin. Multiple groups of suction holes 40 are provided on the outer wall of the chamber; a first servo motor 34 is fixedly installed at the center position of the outer wall of one of the side panels 31 through a bracket, and the output end of the first servo motor 34 passes through the center position of the circle of the side panel 31, and one end of the suction cylinder 39 is sealed. The sealed end of the suction cylinder 39 passes through the side wall of the dispersion cylinder 30, and the output end of the first servo motor 34 is fixedly connected to the sealed end of the suction cylinder 39. A plurality of second servo motors 35 are fixedly installed in a circular array on the outer wall of the side panel 31, and a sensing block 37 is installed on the cylindrical outer wall of each of the second material pipes 36 through an L-shaped bracket. When the positions of the third butterfly valve 38 and the second butterfly valve 23 correspond to each other up and down, the sensing block 37 is aligned up and down with the position of the inductive proximity switch 25.

[0030] During use, the control system controls the directional rotation of the first servo motor 34. When the second material pipe 36 rotates to the top, the second material pipe 36 is close to the bottom of the feeding box 20, and the second butterfly valve 23 is aligned with the third butterfly valve 38. At this time, the sensing block 37 and the inductive proximity switch 25 are aligned up and down and closest to each other. The sensing block 37 sends a signal to the control system. At this time, the control system controls the first servo motor 34 to stop rotating and stop working. At this time, the dispersion cylinder 30 is in a stationary state, which facilitates the smooth discharge of the mineral material in the feeding box 20 into the dispersion cylinder 30. An encoder can also be installed on the output shaft of the first servo motor 34 to monitor the rotation angle of the dispersion cylinder 30. When the encoder detects that the cumulative rotation angle reaches the set angle, the encoder outputs a signal to the control system and then shuts down the first servo motor 34. It is worth noting that an electromagnetic brake can also be installed on the output shaft of the first servo motor 34. When the control system gives a model to control the first servo motor 34 to be turned off, in order to prevent the dispersion cylinder 30 from continuing to rotate under the action of inertia, the control system controls the electromagnetic brake to lock the output end of the first servo motor 34, so that the output shaft of the first servo motor 34 is urgently stopped. In this way, the dispersion cylinder 30 can completely stop working. The encoder and the electromagnetic brake can be used according to actual selection. The encoder and the electromagnetic brake are both existing technologies and will not be elaborated here.

[0031] like Figure 4 、 Figure 12 、 Figure 10 As shown, an active rod 42, a third driven rod 45, a second driven rod 44 and a first driven rod 43 are also provided in the cavity of each of the feeding purification bins. The active rod 42, the third driven rod 45, the second driven rod 44 and the first driven rod 43 are all rotatably mounted on the inner walls on both sides of the cavity of the dispersion cylinder 30. The active rod 42 and the third driven rod 45 are respectively located in the feeding purification bin cavity away from the side of the suction cylinder 39, the second driven rod 44 is located in the feeding purification bin cavity close to the suction cylinder 39, and the first driven rod 43 is located on the side of the second driven rod 44 away from the suction cylinder 39. One end of the active rod 42 movably penetrates one side wall of the dispersion cylinder 30, and the output end of the second servo motor 35 movably penetrates the side wall of the side plate 31. The second servo motor The output end of 35 is fixedly connected to the corresponding active rod 42, and a transmission belt 46 is movably installed between the active rod 42, the second driven rod 44, the third driven rod 45 and the first driven rod 43 in each feeding purification chamber. The transmission belt 46 is V-shaped after passing around the active rod 42, the second driven rod 44, the third driven rod 45 and the first driven rod 43; a second suction pipe 33 is fixedly installed at the center position of the side wall of the other side plate 31, and the second suction pipe 33 passes through the side plate 31 on this side. The other end of the suction cylinder 39 is hollow, and the other end of the suction cylinder 39 movably passes through the side wall of the dispersion cylinder 30. The other end of the suction cylinder 39 is sealed and rotatably connected to one end of the second suction pipe 33, and the second suction pipe 33 is connected to a negative pressure vacuum cleaner.

[0032] Furthermore, when the ore has completely passed through the second material pipe 36 and entered the dispersion cylinder 30 cavity, the second butterfly valve 23 is closed again, and the third butterfly valve 38 after the ore is completely loaded is closed. The control system controls the dispersion cylinder 30 to rotate slowly in a directional manner. At this time, the ore has completely entered the material feeding purification bin and fallen onto the conveyor belt 46. The conveyor belt 46 is guided by the active rod 42, the second driven rod 44, the third driven rod 45, and the first driven rod 43 to form a V-shaped whole. The ore is located in the V-shaped groove of the conveyor belt 46. The control system controls the second servo motor 35 to rotate. When the second servo motor 35 is working, it drives the active rod 42 to rotate. When the active rod 42 rotates, the active rod 42 drives the The motion of the dynamic conveyor belt 46 causes the ore in the V-shaped groove of the conveyor belt 46 to continuously move. In conjunction with the rotation of the dispersion cylinder 30, the ore can be tumbled in each feeding and purification bin, dispersing the dust on the ore. The control system controls the negative pressure vacuum cleaner to operate, creating a negative pressure in the suction cylinder 39 cavity. The dust generated in each feeding and purification bin is sucked away by the negative pressure through the suction holes 40. When the ore tumbles, the conveyor belt 46 may also be contaminated with a lot of dust. Under the continuous motion of the conveyor belt 46, the outer wall of the conveyor belt 46 contaminated with dust will approach the suction holes 40. When passing through the suction holes 40, the dust can be sucked away, reducing the degree of dirt on the conveyor belt 46. By tumbling the ore in each feeding and purification bin, the ore can be effectively dusted and the dust generated by the ore falling on the belt is reduced.

[0033] like Figure 2 、 Figure 4 、 Figure 5 、 Figure 9 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 16As shown, the bottom plate 50 is located just above the belt, and the bottom plate 50 is fixedly connected to the wall surfaces on both sides of the cavity of the sorting body 10 with fixed rods 51, and the fixed rods 51 are fixedly connected to the inner wall of the sorting body 10. The bottom plate 50 is in a horizontal state, and the first baffle 52 and the second baffle 53 are fixedly installed on the top and side walls of the bottom plate 50 respectively. The dividing plate 56 is located between the first baffle 52 and the second baffle 53, and the top of the dividing plate 56 is conical. The third baffle 54 for blocking the material is also installed on the two side walls between the first baffle 52 and the second baffle 53. A plurality of first cylinders 55 are fixedly installed on the outer wall of the first baffle 52, and a bulk material passage is formed between the two adjacent dividing plates 56. A push plate 57 is movably installed in each bulk material channel, the first cylinder 55 corresponds to the push plate 57 in position, the piston rod of the first cylinder 55 movably passes through the first baffle 52 and the piston rod of the first cylinder 55 is fixedly connected to the corresponding push plate 57, the second baffle 53 is provided with a discharge port 58 corresponding to the position of the bulk material channel, and multiple groups of second mounting plates 59 are fixedly installed on the outer wall of the second baffle 53, and a second cylinder 60 is fixedly installed on the bottom of each second mounting plate 59, and the piston rod of the second cylinder 60 is fixedly connected to a blocking plate 61, which corresponds to the position of the discharge port 58, and a mounting groove is provided on the lower side wall of the blocking plate 61, in which a pressure sensor 62 is installed.

[0034] Specifically, when the second material pipe 36 at the bottom of the dispersion cylinder 30 is aligned with the dividing plate 56 on the bottom plate 50, the third butterfly valve 38 on the second material pipe 36 can be controlled by the control system to open. At this time, the third butterfly valve 38 in the second material pipe 36 at the top of the dispersion cylinder 30 can also be in an open state, and the mineral material in the feeding box 20 enters the second material pipe 36 at the top. At this time, the third butterfly valve 38 in the second material pipe 36 at the bottom is opened, so that the mineral material after the tumbling process is discharged into the bulk material channel through the third butterfly valve 38, and the randomly falling mineral material will be randomly The ore falls randomly into the bulk material channel, and the control system controls multiple groups of first cylinders 55 to work synchronously. The piston rod of the first cylinder 55 pushes the push plate 57 to move in the bulk material channel. When the push plate 57 pushes, the ore moves toward the side of the discharge port 58. At this time, the bottom end of the blocking plate 61 is in contact with the top wall of the bottom plate 50. When the push plate 57 pushes the ore close to the pressure sensor 62 and produces a certain squeezing effect, the pressure sensor 62 transmits a signal to the control system. At this time, the ore in the bulk material channel is close to or in contact with each other, and Close to the discharge port 58 on this side, the control system controls the first cylinder 55 to stop working, and the other first cylinders 55 continue to push the work. When the pressure sensor 62 corresponding to the first cylinder 55 generates a signal, it indicates that the mineral materials in the corresponding bulk material channel are already in contact with each other. Only when the mineral materials are in contact with each other, the push plate 57 pushes all the mineral materials to generate an extrusion force on the pressure sensor 62. When the pressure sensor 62 generates a signal and transmits it to the control system, the control system first controls the first cylinder 55 to stop working, and then controls the corresponding second cylinder 55 to stop working. When the air cylinder 60 is working, the second air cylinder 60 drives the blocking plate 61 upward through the piston rod. After the blocking plate 61 moves upward, the blocking plate 61 removes the obstruction of the discharge port 58. After the second air cylinder 60 completes its work, the control system controls the first air cylinder 55, which had previously stopped working, to resume working. When the first air cylinder 55 works again, it slowly pushes the push plate 57 forward. At this time, the ore in the bulk material channel should be in a state of being slowly pushed forward. After passing through the discharge port 58, the ore is directly pushed into the corresponding discharge pipe 67, and finally discharged onto the belt through the discharge pipe 67. After completing the pushing of all the ore in each bulk material channel, the control system controls the first air cylinder 55 and the second air cylinder 60 to reset.

[0035] The mineral materials in each bulk material channel fall randomly, so the amount of mineral materials in each bulk material channel may be different. By randomly dispersing the mineral materials, the dispersed mineral materials enter the bulk material channel and are pushed by the push plate 57. After the mineral materials are pushed to contact each other, it is convenient for the subsequent unloading. The mineral materials that complete the pushing first are pushed and transported first, so as to avoid being transported together with other mineral materials, and a certain time difference in transportation can be achieved. After the transportation is completed, the mineral materials are transported to the belt and then transported and sorted.

[0036] like Figure 13 、 Figure 14 、 Figure 16 、 Figure 17 As shown, the discharge assembly also includes a first limiting rod 63 and a second limiting rod 64. The positions of the discharge pipe 67, the pressure sensor 62 and the discharge port 58 correspond to each other. The second limiting rod 64 is rotatably mounted between two adjacent discharge pipes 67. The first limiting rod 63 is rotatably mounted on the outer walls of the two discharge pipes 67. The other end of the first limiting rod 63 is rotatably mounted on the inner wall of the sorting body 10. The positions of the first limiting rod 63 and the second limiting rod 64 are aligned. The end of the discharge pipe 67 away from the pressure sensor 62 is tilted downward, and the upper end of the discharge pipe 67 is close to the pressure sensor 62. Figure 17 、 Figure 16 As shown, an eccentric wheel 68 is provided below each discharge pipe 67. A drive rod 66 is fixedly mounted on multiple sets of eccentric wheels 68. A third servo motor 65 is fixedly mounted on the inner wall of one side of the cavity of the sorting machine body 10 via a bracket. The output end of the third servo motor 65 is fixedly connected to one end of the drive rod 66 via a shaft coupling. The other end of the drive rod 66 is rotatably mounted on the inner wall of the sorting machine body 10. A tension spring 69 is also fixedly mounted between the upper bottom wall of the discharge pipe 67 and the outer wall of the end of the bottom plate 50. The lengths of the multiple sets of discharge pipes 67 vary, and there is a length difference between adjacent discharge pipes 67.

[0037] Furthermore, when the control system controls the second cylinder 60 to work, the control system synchronously controls the third servo motor 65 to work. When the third servo motor 65 is working, the third servo motor 65 drives the driving rod 66 to rotate. When the driving rod 66 rotates, the driving rod 66 drives multiple sets of eccentric wheels 68 to rotate. When the eccentric wheel 68 rotates, the eccentric wheel 68 can intermittently drive the discharge pipe 67 to shake slightly in an eccentric state. A tension spring 69 is installed between the discharge pipe 67 and the base plate 50. Under normal circumstances, under the elastic force of the tension spring 69, the upper end of the discharge pipe 67 is close to the top wall of the base plate 50. When the eccentric wheel 68 intermittently lifts and shakes the individual discharge pipe 67, after the ore is pushed into the discharge pipe 67, the ore will also shake with the discharge pipe 67. This not only accelerates the discharge of the ore, but also avoids the problem of clogging of the ore when there is a lot of ore. It is worth noting that, because the upper end walls of two adjacent discharge pipes 67 are rotatably connected by the second limit rod 64, and the discharge pipes 67 on both sides are rotatably installed by the first limit rod 63, each discharge pipe 67 can be shaken to discharge materials individually, and when the discharge pipe 67 is shaken, the discharge pipe 67 is shaken significantly on the side away from the discharge port 58, so the upper end of the discharge pipe 67 will not shake significantly, but will only swing slightly, which will not affect the entry of the mineral material into the discharge pipe 67 through the discharge port 58.

[0038] Because the length of the discharge pipe 67 is different, specifically as Figure 18 As shown, two adjacent discharge pipes 67 can be set to have a certain length difference. This setting is to allow the mineral materials to be discharged onto the belt in a staggered manner, and the mineral materials are transported through the previous time difference. Then, through the staggered discharge, the positions of the mineral materials on the belt are placed in a certain order. After being guided by each discharge pipe 67, the mineral materials will fall onto the corresponding belt surface through the discharge pipe 67. There is a certain distance between the two adjacent discharge pipes 67, so the mineral materials falling on the belt will also have a similar distance. In this way, the mineral materials are dispersed on the belt in a certain order as much as possible, avoiding the accumulation of mineral materials, causing inaccurate subsequent sorting problems, and improving the sorting efficiency of the mineral materials.
