[0075] The present invention provides a beneficiation device 1000.

[0076] Please refer to Figure 1 and Figure 2 , a beneficiation device 1000, the beneficiation device 1000 comprising: a frame 100; a transmission assembly 200 disposed on the frame 100; a feeding assembly 300 disposed on the frame 100, the feeding assembly 300 being located at the head end in the transmission direction of the transmission assembly 200 for providing ore to the transmission assembly 200; an ore imaging assembly 400 disposed on the frame 100 for photographing and identifying the ore on the transmission assembly 200; and a screening assembly 500 disposed on the frame 100 and electrically connected to the ore imaging assembly 400, the screening assembly 500 being located at the end in the transmission direction of the transmission assembly 200 for classifying and screening the ore at the end in the transmission direction of the transmission assembly 200 according to the identification result of the ore imaging assembly 400.

[0077] In this embodiment, the feeding assembly 300, the feeding assembly 300, the ore imaging assembly 400 and the screening assembly 500 are sequentially disposed on the frame 100. Among them, the feeding assembly 300 is located at the head end in the transmission direction of the transmission assembly 200 for providing ore on the transmission assembly 200. For example, the feeding assembly 300 may be a vibrating feeder or a conveyor feeder to automatically convey ore onto the transmission assembly 200. The transmission assembly 200 may be a belt 210 mechanism or a crawler mechanism, etc. Using the belt 210 mechanism and the crawler mechanism, the ore is conveyed to the screening assembly 500. The ore imaging assembly 400 is disposed between the feeding assembly 300 and the screening assembly 500 and is used for photographing and identifying the ore on the transmission assembly 200 to identify minerals and waste rocks in the ore. The ore imaging assembly 400 may be an X-ray component or an industrial imaging device, etc. The screening assembly 500 is disposed at the end in the transmission direction of the transmission assembly 200. After the ore imaging assembly 400 photographs and identifies the ore on the transmission assembly 200, the identification data is transmitted to the central control module of the beneficiation device 1000, and the ore imaging assembly 400 can be electrically connected to the screening assembly 500 through the central control module. The screening assembly 500 classifies and screens the ore at the end in the transmission direction of the transmission assembly 200 according to the identification result of the ore imaging assembly 400. The screening assembly 500 may include a sieve mesh to facilitate screening of ores of different sizes. It can be understood that the screening assembly 500 may also be a manipulator to grasp ores of different sizes using the manipulator. Through the above structure, the ore can be efficiently conveyed and screened, improving the beneficiation efficiency.

[0078] Specifically, the transmission component 200 includes: a belt 210, the belt 210 is drivingly arranged on the frame 100, the feeding component 300 is located at the head end of the transmission direction of the belt 210, and the screening component 500 is located at the tail end of the transmission direction of the belt 210; two sets of edge retaining mechanisms 220, both sets of the edge retaining mechanisms 220 are arranged on the frame 100, both sets of the edge retaining mechanisms 220 are located above the belt 210, both sets of the edge retaining mechanisms 220 are arranged along the transmission direction of the belt 210, and both sets of the edge retaining mechanisms 220 are respectively located on both sides of the transmission direction of the belt 210 to enclose both sides of the transmission direction of the belt 210; a cover plate 230, the cover plate 230 is arranged on the frame 100, the cover plate 230 is located above the belt 210, both sets of the edge retaining mechanisms 220 are connected to the cover plate 230, and the belt 210, both sets of the edge retaining mechanisms 220 and the cover plate 230 form a sealed material conveying cavity A. Please refer to Figure 1 and Figure 8 , in this embodiment, the belt 210 is drivingly arranged on the frame 100, and ore is placed on the belt 210. Since the transmission device itself will vibrate, as the belt 210 transports, after the ore is vibrated, it is easy to fall from both sides of the transmission direction of the belt 210. In order to prevent the above-mentioned phenomenon of the ore falling, two sets of edge retaining mechanisms 220 are arranged on the frame 100. The edge retaining mechanisms 220 can be baffle mechanisms, etc. Both sets of the edge retaining mechanisms 220 are located above the belt 210, both sets of the edge retaining mechanisms 220 are arranged along the transmission direction of the belt 210, and both sets of the edge retaining mechanisms 220 are respectively located on both sides of the transmission direction of the belt 210 to enclose both sides of the transmission direction of the belt 210. When the belt 210 vibrates, the ore on the belt 210 vibrates continuously, and the ore located on both sides of the transmission direction of the belt 210 is blocked on the belt 210 by the edge retaining mechanisms 220, and the gap between the side of the edge retaining mechanism 220 facing the belt 210 and the surface of the belt 210 is smaller than the size of the ore, preventing the ore from falling below the belt 210 along the above gap. At the same time, a cover plate 230 is arranged on the frame 100, the cover plate 230 is located above the belt 210, both sets of the edge retaining mechanisms 220 are connected to the cover plate 230, and the belt 210, both sets of the edge retaining mechanisms 220 and the cover plate 230 form a sealed material conveying cavity A, which can effectively prevent the ore on the belt 210 from falling and reduce the waste of ore.

[0079] In order to further prevent the ore from falling from the belt 210, the belt 210 and the two sets of edge retaining mechanisms 220 form a U-shaped structure. The ore can vibrate continuously between the two sets of edge retaining mechanisms 220 without falling outside the belt 210. At the same time, the concave structure can better gather the ore on the belt 210.

[0080] Specifically, in order to better prevent the ore from falling off the belt 210, the two sets of edge retaining mechanisms 220 are arranged obliquely with respect to the belt 210, and the two sets of edge retaining mechanisms 220 are symmetrically arranged about the central axis of the belt 210, and the central axis is parallel to the transmission direction. In this embodiment, the two sets of edge retaining mechanisms 220 are obliquely arranged and symmetric with each other, and form a concave structure with the belt 210. When the ore vibrates and rebounds onto the edge retaining mechanism 220, the inclined edge retaining mechanism 220 can make the ore fall back onto the belt 210 along the inclined direction.

[0081] Specifically, the edge retaining mechanism 220 includes: a fixing member 221, the fixing member 221 is arranged on the frame 100; a retaining bar 222, the retaining bar 222 is detachably arranged on the fixing member 221, wherein, after the retaining bar 222 is stressed, the retaining bar 222 abuts against the upper surface of the belt 210. As an optional embodiment, the edge retaining mechanism 220 may include a fixing member 221 and a retaining bar 222. Among them, the fixing member 221 is fixed on the frame 100, and the retaining bar 222 is detachably fixed at a fixed point. In order to prevent the ore from falling from both sides of the belt 210 in the transmission direction, after the retaining bar 222 is stressed, the retaining bar 222 can be made to abut against the belt 210 to prevent the ore from falling through the gap between the retaining bar 222 and the surface of the belt 210. The edge retaining mechanism 220 further includes: a second connecting member 223, a connecting hole is provided on the second connecting member 223, the second connecting member 223 is arranged on the retaining bar 222; a fastening member, the fastening member is arranged in the connecting hole, the fastening member sequentially passes through the second connecting member 223, the retaining bar 222 and the fixing member 221, and the second connecting member 223, the retaining bar 222 and the fixing member 221 are fixedly connected through the fastening member.

The second connecting member 223 is arranged on the retaining bar 222, and a plurality of fixing members 221 are provided. The fastening member can be in threaded cooperation with the connecting hole. The fastening member sequentially passes through the second connecting member 223, the retaining bar 222 and the fixing member 221, and the second connecting member 223, the retaining bar 222 and the fixing member 221 are fixedly connected through the fastening member. When the retaining bar 222 needs to be replaced, only the second connecting member 223 and the fastening member need to be disassembled. The retaining bar 222 is made of an elastic material. In this embodiment, in order to further prevent the ore from falling off the belt 210, the retaining bar 222 is made of an elastic material. After the retaining bar 222 is stressed, the retaining bar 222 can be made to abut against the belt 210, and the ore rebounds from the retaining bar 222 onto the belt 210 to prevent the ore from falling through the gap between the retaining bar 222 and the surface of the belt 210.

[0082] Specifically, the fixing member 221 includes: a fixing portion (not labeled in the figure), which is fixedly connected to the frame 100; an extending portion (not labeled in the figure), which is integrally formed with the fixing portion. The extending portion is inclined towards the belt 210. The baffle 222 is disposed on the extending portion. A first reinforcing rib 224 is provided between the extending portion and the fixing portion. In this embodiment, the fixing member 221 includes a fixing portion and an extending portion. The fixing portion is fixed to the frame 100, and the extending portion is integrally formed with the fixing portion. To improve the strength of the fixing member 221, a first reinforcing rib 224 can be provided between the fixing portion and the extending portion. The inclination angle between the fixing portion and the extending portion is greater than 90°.

The baffle 222 is attached to the extending portion, and the inclination angle of the baffle 222 is the same as that of the extending portion. After the baffle 222 is stressed, the baffle 222 rotates and displaces towards the belt 210, generating a resilience force. The greater the inclination angle between the fixing portion and the extending portion, the greater the resilience force, which can make the baffle 222 abut against the belt 210, and the ore rebounds from the baffle 222 to the belt 210. A first mounting hole (not shown in the figure) is provided on the fixing portion. In this embodiment, to facilitate fixing the fixing portion to the frame 100, a plurality of first mounting holes can be provided on the fixing portion.

When the ore is transported from the feeding component 300 to the chute plate 262, the ore can be accelerated through the chute plate 262, so that the ore has a certain speed after passing through the chute plate 262. Thus, when the ore is transported to the transmission component 200, the speed of the ore matches the speed of the transmission component 200. Among them, the adapter is a sheet metal connecting plate, that is, one end of the sheet metal connecting plate is fixed on the mounting frame 261, and the chute plate 262 is fixed at the other end of the sheet metal connecting plate to stabilize the chute plate 262 in sequence.

[0087] Specifically, as Figure 13 shown, each of the chute plates 262 is installed on the mounting frame 261, and the chute plates 262 are arranged side by side. Among them, the chute plate 262 is arranged at an acute angle or an obtuse angle with the horizontal plane. In this embodiment, the chute plates 262 are arranged side by side on the mounting frame 261, and the chute plate 262 forms an acute angle α with the horizontal plane, or the chute plate 262 forms an obtuse angle β with the horizontal plane. Among them, the sum of the above acute angle α and the above obtuse angle β is 180°.

[0088] Furthermore, since the ore directly falls on the plane of the chute plate 262, that is, the chute plate 262 in this embodiment is made of a material with a relatively high hardness to improve the service life of the chute plate 262, such as: stainless steel, etc., there is no limitation here. The split chute mechanism 260 includes a mounting frame 261 and a plurality of chute plates 262. Each of the chute plates 262 is installed on the mounting frame 261, and the chute plates 262 are arranged side by side. Among them, the chute plate 262 is arranged at an acute angle or an obtuse angle with the horizontal plane. By replacing the existing large-size chute plate 262 with three smaller-size chute plates 262, the weight of each chute plate 262 can be reduced, which is convenient for replacement.

[0089] Furthermore, as Figures 11 to 12 shown, in this embodiment, the positional relationships and the achieved effects of all the chute plates 262 are the same. Among them, taking one of the plurality of chute plates 262 as an example, the description is as follows:

[0090] The cross slide 262 includes a first part 2621, a second part 2622 and a third part 2633, and the first part 2621, the second part 2622 and the third part 2633 can be of a split structure, or the first part 2621, the second part 2622 and the third part 2633 can be of an integral structure. For example, when the first part 2621, the second part 2622 and the third part 2633 can be of a split structure, the second part 2622 is connected to one end of the first part 2621, and the third part 2633 is connected to the other end of the first part 2621; when the first part 2621, the second part 2622 and the third part 2633 can be of an integral structure, the first part 2621, the second part 2622 and the third part 2633 are integrally formed and the first part 2621 is located between the second part 2622 and the third part 2633. The first part 2621 is a square plate, and the above square plate is inclined, that is, the square plate is arranged at an acute angle or an obtuse angle with the horizontal plane. In this embodiment, in order to enable the speed of the ore material to reach a preset speed after passing through the first part 2621, the angle range of the acute angle α formed between the first part 2621 and the horizontal plane is 30° to 70°; or, the angle range of the obtuse angle β formed between the first part 2621 and the horizontal plane is 110° to 150°. The angle range of the acute angle α formed between the first part 2621 and the horizontal plane is 50°; or, the angle range of the obtuse angle β formed between the first part 2621 and the horizontal plane is 130°. Of course, in other embodiments, the acute angle α or the obtuse angle β can also be set to other values, and there is no limitation here.

[0091] Specifically, the outer surfaces of the second part 2622 and the third part 2633 are both arc-shaped surfaces. Among them, the first part 2621 has a contact surface, and in this embodiment, the contact surface is the surface in contact with the ore material, that is, the arc-shaped part of the arc-shaped surface of the second part 2622 protrudes relative to the contact surface, so that after the ore material passes through the protruding arc-shaped part of the second part 2622, the ore material has a tendency to be thrown downward, and under the gravity of the ore material, it falls on the contact surface of the first part 2621 and rolls.

[0092] Specifically, the arc-shaped part of the arc-shaped surface of the third part 2633 is recessed relative to the contact surface, that is, when the ore material rolls from the contact surface of the first part 2621 to the arc-shaped part of the arc-shaped surface of the third part 2633, the ore material is thrown out from the recessed arc-shaped part, and it has a power parallel to the transmission direction of the transmission assembly 200, so that the ore material smoothly falls on the transmission assembly 200 and is conveyed through the transmission assembly 200.

[0093] Specifically, the split chute mechanism 260 further includes a baffle 264, and a material inlet I is formed on the baffle 264. The material inlet I is disposed at the position of the second part 2622. The size of the material inlet I can be set to limit the quantity of the ore material transmitted to the chute plate 262, so that the ore material transmitted to the chute plate 262 can meet the maximum bearing weight of the chute plate 262, thereby improving the service life of the chute plate 262.

[0094] Specifically, the ore imaging assembly 400 includes: a ray receiving mechanism 410; a ray emitting mechanism 420, the ray emitting mechanism 420 is disposed on the frame 100, and the transmission assembly 200 is located on the path of the rays emitted by the ray emitting mechanism 420; a first protective housing 430, the first protective housing 430 is disposed on the frame 100, a first storage cavity F is provided in the first protective housing 430, the ray receiving mechanism 410 is located in the first storage cavity F, the first protective housing 430 is made of a lead plate, and a first opening (not marked in the figure) is formed on the first protective housing 430; wherein, the rays emitted by the ray emitting mechanism 420 sequentially pass through the transmission assembly 200 and the first opening and are received by the ray receiving mechanism 410. As Figures 1 to 10 shown, in this embodiment, the ore imaging assembly 400 mainly includes a ray receiving mechanism 410, a ray emitting mechanism 420 and a first protective housing 430. The ray receiving mechanism 410 may be an X-ray mechanism. When the transmission assembly 200 continuously transports the ore material, the X-ray mechanism takes an X-ray photo of the ore material on the transmission assembly 200. The rays sequentially penetrate through the ore material and the transmission assembly 200, and enter the first protective housing 430 through the first opening. The ray receiving mechanism 410 is located in the first storage cavity F of the first protective housing 430 to receive the rays and generate photographing parameters. The ray receiving mechanism 410 can be electrically connected to the central control module to transmit the photographing parameters to the central control module.

[0095] Specifically, the ore imaging assembly 400 includes: a light transmissive member 440, and the light transmissive member 440 covers the first opening. In this embodiment, the light transmissive member 440 can be covered at the first opening. If a steel plate is directly used to replace the light transmissive member 440, it is difficult for the rays to enter the ray receiving assembly. Therefore, using the light transmissive member 440 can enable the rays to enter the ray receiving assembly with as little loss as possible. The light transmissive member 440 can be made of an epoxy board, a fiberglass board, a carbon fiber board, etc., to prevent the ray receiving assembly from being unable to accurately obtain the above rays, resulting in inaccurate acquisition results.

[0096] Specifically, the ray emission mechanism 420 includes: a ray emitter 421, which is disposed on the frame 100; a protective cover 450, within which a channel penetrating the protective cover 450 is defined, and the channel extends from the ray emitter 421 towards the position of the first opening; a sealing cover 460, which is provided with a light-transmitting slit G, and the sealing cover 460 covers one end of the protective cover 450 away from the ray emitter 421, and the light-transmitting slit G is oriented towards the first opening. In this embodiment, the ray emitter 421 can be selectively disposed at the end of the transmission direction of the transmission assembly 200. The transmission assembly 200 can be a belt 210, which is drivingly disposed on the frame 100. The belt 210 can be an annular structure or a single-layer belt 210 structure, etc. The single-layer belt 210 is located between the ray emitter 421 and the ray receiving mechanism 410. To prevent the rays from irradiating other positions, a protective cover 450 can be added to the ray emitter 421. A channel is defined within the protective cover 450, and the channel has two channel openings. One of them is disposed at the emission opening position of the ray emitter 421, such that the channel extends from the ray emitter 421 towards the position of the first opening. As the transmission assembly 200 transmits, the ore continuously passes below the ray emitter 421. The rays emitted by the ray emitter 421 are covered by the protective cover 450, and the rays cannot scatter to other positions. Moreover, the rays are concentrated and emitted towards the first opening through the light-transmitting slit G on the sealing cover 460, so as to accurately transmit the ore.

[0097] Specifically, in order to attenuate the rays, a second protective housing 470 may be provided. The second protective housing 470 is provided with a storage groove, and the first protective housing 430 is disposed in the storage groove. The notch of the storage groove abuts and seals against the upper end of the first protective housing 430, and an attenuation gap is formed between the first protective housing 430 and the second protective housing 470. After the ray receiving mechanism 410 receives the rays of the ray emitting mechanism 420 through the first opening, since there are still heat-dissipating rays between the first protective housing 430 and the second protective housing 470, both the first protective housing 430 and the second protective housing 470 are made of lead plates. The second protective housing 470 can effectively block the rays between the first protective housing 430 and the second protective housing 470, and both the first protective housing 430 and the second protective housing 470 are made of lead plates, which can effectively attenuate the intensity of the rays and prevent the rays from damaging other components. The cross-section of the second protective housing 470 is U-shaped. The first protective housing 430 includes: a lower housing 431, on which the ray receiving mechanism 410 is disposed, and the lower housing 431 is disposed on the bottom of the storage groove; an upper housing 432, on which the first opening is formed, and the upper housing 432 is detachably disposed on the lower housing 431, and the upper housing 432 seals the storage groove, and the second protective housing 470 and the lower housing 431 form an attenuation gap. In this embodiment, in order to facilitate the disassembly of the second protective housing 470, the second protective housing 470 may adopt a split structure. Among them, the first protective housing 430 mainly includes a lower housing 431 and an upper housing 432. The lower housing 431 is disposed on the bottom of the storage groove, the first opening is formed on the upper housing 432, the upper housing 432 is detachably disposed on the lower housing 431, and the upper housing 432 seals the storage groove. The second protective housing 470 and the lower housing 431 form an attenuation gap, effectively attenuating the intensity of the rays and preventing the rays from damaging other components. Secondly, the first opening is formed on the upper housing 432, so that the part of the ray receiving mechanism 410 that receives light is located directly below the first opening.

[0098] As another alternative embodiment, the upper housing 432 is disposed on the frame 100, and the lower housing 431 can be slidably disposed on the upper housing 432 through a guide rail or the like, so as to facilitate the staff to quickly pull the lower housing 431 away from the upper housing 432. The second protective housing 470 is slidably connected to the upper housing 432. The housing further includes: a handle (not labeled in the figure), and the handle is disposed on the second protective housing 470. In this embodiment, in order to facilitate the staff to replace the radiation receiving mechanism 410, a guide rail can be provided between the second protective housing 470 and the upper housing 432 to slidably connect the second protective housing 470 to the upper housing 432, and a handle is provided on the second protective housing 470. When it is necessary to replace the radiation receiving mechanism 410, the staff can pull the second protective housing 470 away from the upper housing 432 through the handle, so as to facilitate the staff to take the radiation receiving mechanism 410.

[0099] Specifically, the screening assembly 500 includes: an air jet valve 510, the air jet valve 510 is disposed on the frame 100, a first slope is provided at the upper end of the air jet valve 510, the air jet nozzle 515 of the air jet valve 510 is cylindrical, and the axis of the air jet nozzle 515 is perpendicular to the first slope, and the air jet nozzle 515 gives an upward jet force to the ore ejected from the end of the conveying direction of the belt 210; a third receiving hopper 520, the third receiving hopper 520 is disposed on the frame 100, a receiving groove H is formed in the third receiving hopper 520, a third inlet P and at least one third outlet Q are formed in the third receiving hopper 520 for the receiving groove H, a partition plate 522 is provided on the third receiving hopper 520, and the partition plate 522 divides the receiving groove H into two partition grooves, each partition groove is communicated with the third inlet P, and each partition groove is provided with the third outlet Q. As Figures 1 to 10 , Figures 14 to 16As shown in the figure, in this embodiment, a jet valve 510 can be provided on the rack 100. The jet valve 510 is located at the end of the conveying direction of the belt 210. A first slope is provided at the upper end of the jet valve 510. When the ore is continuously ejected from the end of the belt 210, the jet nozzle 515 of the jet valve 510 faces upward. As the ore dressing equipment 1000 operates, the fine dust on the ore will fall onto the first slope where the jet nozzle 515 is located. Since the first slope is inclined itself, the dust will fall along the inclined surface of the first slope and will not accumulate on the first slope. Moreover, setting the first slope on the housing also facilitates the cleaning of the dust on the jet valve 510. At the same time, after the ore receives the jet force, its ejection trajectory changes. Since a partition plate 522 is provided in the middle of the receiving chute H, the partition plate 522 divides the receiving chute H into two partition chutes. The two partition chutes of the second receiving hopper 250 are arranged side by side, for example, distributed left and right. The left side is connected to the belt 210. The ore trajectory of the ore receiving the jet force is ejected upward and finally falls into the right partition chute, while the ore not receiving the jet force is naturally ejected into the left partition chute. The ore particles pass through the corresponding third feed inlet P and are uniformly collected through the corresponding third discharge outlet Q. The third receiving hopper 520 includes: a third receiving hopper body 521, a receiving chute H is formed in the third receiving hopper body 521, and a third receiving port and at least one third discharge outlet Q are formed on the third receiving hopper body 521 for the receiving chute H; at least one joint mechanism 530, the joint mechanism 530 is communicated with the third discharge outlet Q, and in the housing forming the third discharge outlet Q, a first annular protrusion 523 is provided on one of them, and an annular groove R is provided on the other. The first annular protrusion 523 is rotatably arranged in the annular groove R. Based on the above structure, the third receiving hopper 520 mainly includes a third receiving hopper body 521 and at least one joint mechanism 530. Among them, a receiving chute H is formed in the third receiving hopper body 521, and a third receiving port and at least one third discharge outlet Q are opened on the third receiving hopper body 521. The third receiving port is communicated with the receiving chute H. The third receiving port is used to receive the ore conveyed by the belt 210, and the number of the joint mechanisms 530 corresponds to that of the third discharge outlets Q one by one. Therefore, the joint mechanism 530 is arranged on the edge of the third discharge outlet Q. Specifically, on the outer edge of the joint mechanism 530 and the third discharge outlet Q, a first annular protrusion 523 is provided on one of them, and an annular groove R is provided on the other. The annular protrusion is rotatably arranged in the annular groove R, so that the joint mechanism 530 can rotate at different angles relative to the third receiving hopper body 521, so as to facilitate draining the ore in the receiving chute H to different workstations and bringing convenience to the aggregate operation.

[0100] Specifically, the first annular protrusion 523 is disposed on the outer edge of the third discharge port Q and is provided on the joint mechanism 530. As an alternative embodiment, the first annular protrusion 523 may be protruded outwardly on the edge of the third discharge port Q, and the first annular protrusion 523 is formed on the joint mechanism 530. After the first annular protrusion 523 is disposed in the annular groove R, the joint mechanism 530 can rotate at different angles relative to the third hopper body 521. The joint mechanism 530 includes: a joint body 531, on which a second annular protrusion 532 is provided, and the joint body 531 is in communication with the third discharge port Q; a first fixed ring 533, which is disposed on the second annular protrusion 532; a second fixed ring 534, which is sleeved on the peripheral wall of the housing forming the third discharge port Q; wherein the first annular protrusion 523 and the first fixed ring 533 are clamped between the second annular protrusion 532 and the second fixed ring 534, and the second annular protrusion 532, the first fixed ring 533 and the second fixed ring 534 together form the annular groove R. In this embodiment, the joint body 531 of the joint mechanism 530 can protrude outwardly to form the second annular protrusion 532 and make the joint body 531 communicate with the third discharge port Q. For example, a through hole penetrating the joint body 531 may be formed on the joint body 531, and the through hole is in communication with the third discharge port Q. In addition, a first fixed ring 533 and a second fixed ring 534 are provided. The first fixed ring 533 is disposed on the second annular protrusion 532, the second fixed ring 534 is sleeved on the peripheral wall of the third discharge port Q and can rotate relative to the discharge port.

When the annular protrusion is rotatably disposed in the annular groove R, the joint structure can rotate at different angles relative to the axis of the annular groove R, so as to facilitate the joint mechanism 530 to drain the ore in the receiving trough H to different workstations, which brings convenience to the aggregate operation.

[0101] Specifically, the second annular protrusion 532, the first fixing ring 533 and the second fixing ring 534 are fixedly connected by screws. As an alternative embodiment, threaded holes communicating with each other may be formed in the second annular protrusion 532, the first fixing ring 533 and the second fixing ring 534. There may be multiple groups of the mutually communicating threaded holes, and multiple fasteners may be used. The fasteners may be screws or the like. The fasteners are in threaded fit with the threaded holes, so as to fixedly connect the second annular protrusion 532, the first fixing ring 533 and the second fixing ring 534 by screws, ensuring the stability of the joint mechanism 530 and the third hopper body 521. The first fixing ring 533 and the second annular protrusion 532 are fixedly connected by welding. In this embodiment, in order to improve the stability between the first fixing ring 533 and the second annular protrusion 532, the first fixing ring 533 and the second annular protrusion 532 may be fixedly connected by welding. The second fixing ring 534 is formed by splicing two half rings, and the two half rings are fixedly connected by screws. In this embodiment, in order to facilitate sleeving the second fixing ring 534 on the peripheral wall of the third discharge port Q, the second fixing ring 534 may be provided with a split structure, that is, two half rings are spliced with each other to form a complete second fixing ring 534. After the two half rings are arranged on the peripheral wall of the third discharge port Q, the two half rings may be fixedly connected by screws, or fixedly connected by welding or the like. The second annular protrusion 532 is provided with fastening holes, and the joint mechanism 530 further includes: a fastener, the fastener is arranged in the fastening holes and is in threaded connection with the fastening holes, and one end of the fastener facing the third hopper body 521 abuts against the first annular protrusion 523.

The fasteners may be screws or bolts or the like. The fasteners are in threaded fit with the fastening holes. After the joint body 531 rotates a certain angle, the first annular protrusion 523 can be fastened in the annular groove R by the fasteners. At this time, one end of the fastener facing the third hopper body 521 abuts against the first annular protrusion 523.

In this embodiment, a plurality of air outlet interfaces H are provided on the valve body 513, and each air outlet interface H is connected to each of the air nozzles 515 through the U-shaped air pipe 516, so as to store foreign matter at the bottom of the U-shaped air pipe 516, and blow the foreign matter at the bottom of the U-shaped air pipe 516 out from the air nozzle 515 when the valve body 513 blows air next time. The U-shaped air pipe 516 includes a first port 5161, a second port 5162, and a storage portion 5163 provided between the first port 5161 and the second port 5162, the first port 5161 is connected to the air nozzle 515, the second port 5162 is connected to the air outlet interface H, and the storage portion 5163 is the bottom of the U-shaped air pipe 516, and is configured to store foreign matter such as muddy water, fine sand, etc., which flows into the U-shaped air pipe 516 from the air nozzle 515 and the first port 5161. The number of the air nozzles 515 is plural, the number of the air outlet interfaces H corresponds to the number of the air nozzles 515, and each of the air nozzles 515 is connected to the corresponding air outlet interface H through a U-shaped air pipe 516, so that each of the air nozzles 515 can be connected to the valve body 513, so that the gas can be ejected from the air nozzle 515 through the valve body 513. In this embodiment, when the gas is ejected from the air nozzle 515 through the valve body 513, the gas blows away the foreign matter stored in the storage part 5163 and is discharged from the air nozzle 515.

[0103] Optionally, the U-shaped air pipe 516 is a PU hose. However, in other embodiments, the U-shaped air pipe 516 may also be made of other types of hoses, which is not limited herein. In an embodiment of the present invention, the jet valve 510 includes a bottom plate 511, a side plate assembly 512, a plurality of valve bodies 513, and a mounting member 514. The side plate assembly 512 is mounted on the bottom plate 511, and the side plate assembly 512 and the bottom plate 511 enclose a receiving cavity. Each of the valve bodies 513 is mounted on the side plate assembly 512 and is located within the receiving cavity. The mounting member 514 is provided at one end of the side plate assembly 512 facing away from the bottom plate 511, and a plurality of jet nozzles 515 are provided on the mounting member 514. A plurality of air outlet interfaces H are provided on the valve body 513, and each of the air outlet interfaces H is connected to each of the jet nozzles 515 through the U-shaped air pipe 516 to store foreign objects at the bottom of the U-shaped air pipe 516, and when the valve body 513 blows air next time, the foreign objects at the bottom of the U-shaped air pipe 516 are blown out from the jet nozzles 515. That is, in the present invention, by providing the U-shaped air pipe 516 and storing foreign objects such as muddy water and fine sand at the bottom of the U-shaped air pipe 516, foreign objects are prevented from directly entering the interior of the valve body 513, causing blockage of the valve body 513. The air outlet direction of the air outlet interface H is set towards the direction of the bottom plate 511, that is, the air outlet interface H is set downward, so that dust in the receiving cavity can enter the valve body 513 from the air outlet interface H, causing blockage of the valve body 513, thereby damaging the valve body 513.

[0104] Further, in order to enable the storage portion 5163 of the U-shaped air pipe 516 to store a sufficient amount of foreign objects and prevent the foreign objects from flowing back into the valve body 513, the distance range between the lowest point of the storage portion 5163 and the second port 5162 is 30 mm to 80 mm, and the distance d between the bottom of the U-shaped air pipe 516 and the air outlet interface H ranges from 30 mm to 80 mm. In this embodiment, the distance d between the lowest point of the storage portion 5163 and the second port 5162 is set to 50 mm, so that the storage portion 5163 has sufficient storage space for storing foreign objects. Of course, in other embodiments, the distance between the lowest point of the storage portion 5163 and the second port 5162 may also be set to other values, as long as the foreign objects stored in the storage portion 5163 do not flow back into the valve body 513, which is not limited herein.

[0105] Further, the jet valve 510 further includes a gas storage chamber 517 disposed in the accommodation cavity. An air inlet K is provided on the gas storage chamber 517, and the air inlet K is connected to an external air pump (not shown in the figure) through a first air pipe to deliver gas into the gas storage chamber 517. The gas storage chamber 517 is configured to store the gas input by the external air pump. A plurality of air outlets are further provided on the gas storage chamber 517, and a plurality of air inlet interfaces (not marked in the figure) are further provided on the valve body 513. Each of the air inlet interfaces is correspondingly connected to the air outlet through a second air pipe, so that the gas in the gas storage chamber 517 is delivered into the valve body 513. Of course, it can be understood that each air outlet corresponds to one air inlet interface. That is, when one of the jet nozzles 515 needs to jet air, it is necessary to locate to the air outlet interface H corresponding to the jet nozzle 515, and through the air outlet interface H, locate to the air inlet interface and the air outlet corresponding to the air inlet interface, so as to transmit the gas stored in the gas storage chamber 517 through the air outlet to the corresponding air outlet interface H and the jet nozzle 515 to achieve precise positioning. In order to enable the jet nozzle 515 to jet air, the valve body 513 includes a valve core 518 and a control board 519, and the valve core 518 is electrically connected to the control board 519.
