[0032] Combination Figure 1 It is the overall structure diagram of the present invention;

[0033] The present embodiment provides a coal gangue sorting device, including a transport device 100 for transporting coal gangue flow and a sorting execution component 200 mounted above the transport device in a transversely rotatable manner, the sorting execution component having at least one claw, and when the sorting execution component rotates, the claw is driven to move the gangue on the transport device transversely to the outside of the transport device.

[0034] Transverse rotation means rotation around the longitudinally extending central axis, wherein the longitudinal direction is the length direction of the transport device, and the transverse direction is the width direction of the transport device. In this embodiment, the transport device adopts belt transport, and the belt is driven by a motor and a roller. The belt is installed on a belt frame 101, and a roller is provided on the belt frame for supporting and transporting the belt. Belt transport is a prior art, and the details are not repeated here. Figure 1As shown, a vibrating screen 700 is installed at the head position of the transport device, and the coal gangue flow is supplied to the right end of the transport device through the vibrating screen. The transport device transports the coal gangue flow to the left, wherein the sorting execution component is arranged at the left end position of the transport system. This coal gangue sorting device is used in conjunction with the gangue identification system. When the gangue is identified, the instruction is sent to the existing execution structure. When the gangue runs to the top of the sorting execution component, the sorting execution component rotates so that the claws laterally push the corresponding gangue to the outside of the transport device. The lateral sides of the transport device are provided with the sorting execution components. The gangue chute 800 is matched with the traveling component, and the gangue chute is connected to the gangue storage system. The claw moves the corresponding gangue to the gangue chute 800. The sorting execution component 200 of this structure has a fast execution speed, a high execution frequency, and fewer execution actions, which improves the gangue sorting efficiency. It only needs to control the rotation of the sorting execution component, and its control is simple. In addition, the matching sorting execution component can increase the upper limit of the transportation speed of the transportation device, and can improve the transportation and sorting capacity of the entire coal gangue sorting system. The sorting execution component of this structure removes a large weight of gangue and has a wide range of applications.

[0035] The sorting device also includes a shaping system mounted above the transport device, the shaping system is located in front of the sorting execution component, the shaping system includes a diversion component 300 mounted above the transport device for dividing the coal gangue flow on the transport device into two columns, and a shaping component 400 mounted above the transport device, the shaping component cooperates with the diversion component to control the maximum passing particle size of the two columns of coal gangue flow. The front side is the side opposite to the transportation direction, and the rear side is the side along the transportation direction. The width direction of the gangue flow column is consistent with the width direction of the transportation device. The diverter component is used to arrange the gangue particles into two regular columns. The diverter component is arranged in the middle of the belt, and the shaping component is arranged on both sides of the crossbeam of the diverter component to control the maximum passing particle size of the gangue flow. The width of the gangue flow is controlled by controlling the maximum passing particle size of the gangue flow column. The overall particle size of the gangue flow is controlled by this structure so that it is within the power range of the sorting execution component, and it is divided into two columns of gangue flow. When removing gangue, the gangue in each column of gangue flow is directly pushed out of the transportation device, and the gangue running trajectory does not interfere with the other column of gangue flow.

[0036] Combination Figures 2 to 4 , which are related views of the sorting execution components;

[0037] There are at least two groups of sorting execution components arranged longitudinally, each group includes two sorting execution components arranged in parallel transversely and staggered longitudinally, and the corresponding two sorting execution components in each group respectively correspond to two columns of coal gangue flow to perform sorting operations. The longitudinal staggered setting means that the lateral projections of the claws of the two sorting execution components do not interfere with each other, so that the rotation process of the two sorting execution components does not affect each other, so as to reduce the lateral installation space. The two sorting execution components in each group respectively correspond to two columns of coal gangue flow. When performing the sorting operation, the claws of the sorting execution components rotate to directly push the gangue out of the transport device, and the running trajectory of the moved gangue does not interfere with another coal gangue flow column. In addition, by arranging multiple groups of sorting execution components in parallel longitudinally, it is beneficial to improve the removal efficiency of the sorting execution components and avoid gangue residue.

[0038] The sorting execution assembly includes a sorting drive 201 and a claw body 202 driven by the sorting drive, and the claw body is connected to a plurality of pusher claws 203. The sorting drive is a drive motor, the output shaft of which extends vertically, and the drive motor outputs power through a reducer, and the reducer adopts a right-angle shaft reducer 206, so that the output shaft of the reducer extends longitudinally, and the output shaft of the reducer cooperates with the claw body through a coupling, and the number of pusher claws is adjusted according to the actual use conditions, and the details are not repeated;

[0039] The claw body obliquely extends outward to form two centrally symmetrical connecting parts 204, where central symmetry refers to the symmetry around the claw body's rotation axis. Two approximately parallel claws are respectively connected to the two connecting parts, and approximately parallel means that the two are parallel and allow for certain manufacturing and installation errors. The sorting execution assembly also includes a transmission sleeve 205, and the connecting part is sleeved on the transmission sleeve and cooperates with the transmission sleeve. The claw body includes two support plates 202a sleeved on the transmission sleeve, and the two ends of the support plate extend outward to form two groups of connecting parts corresponding to the two claws one by one, and the claws are fixedly connected to the corresponding connecting parts. Combined with Figure 4 As shown, one end of the support plate extends outward to form a connecting plate 204a, and two axially adjacent parallel connecting plates form a connecting portion. The claw is a plate-shaped structure, and the claw is welded to the two connecting plates. The end of the connecting plate is a chamfered or rounded structure to improve the interference with the coal gangue flow during the rotation process. Figure 2 and Figure 3 As shown, the connecting portion extends obliquely relative to the claw body and the two claw bodies are arranged in parallel, so that when one of the claws rotates to the bottom, the lower claw is located close to the center line of the transportation device, leaving a larger space for the passage of the outer coal gangue flow, which is conducive to the installation of the claw toward the center of the transportation device, facilitates the overall arrangement of the lateral space, and can reduce the lateral installation space.

[0040] The sorting execution component also includes an actuator mounting bracket, which includes an actuator support frame 207 and an actuator mounting frame 208 connected to the actuator support frame. The actuator mounting frame includes a plurality of mounting beams 208a connected to the actuator support frame. Each sorting execution component and the mounting beams are arranged alternately, and the sorting drive is installed on the mounting beams. The actuator support frame 207 has four legs, and the four legs can be installed on the frame of the transport device or on the ground foundation. The actuator mounting frame 208 is a rectangular frame connected to the four legs and a plurality of mounting beams connected to the rectangular frame. The relatively independent mounting space 209 formed between adjacent mounting beams is conducive to the independent installation of each sorting execution component, and the claws of each sorting execution component operate in their own relatively independent spaces, and the sorting execution components do not affect each other.

[0041] The sorting drive member and the corresponding pusher claw are located on both sides of the longitudinal direction of one of the mounting beams. Here, the corresponding pusher claw represents the pusher claw driven by the sorting drive assembly. Based on the fact that the sorting drive member and the corresponding pusher claw are used for power transmission through the reducer, if the entire sorting execution assembly is installed between two adjacent beams, the spacing between the adjacent beams needs to be too large, resulting in a loose structure and insufficient strength of the entire actuator mounting bracket. Therefore, the sorting execution assembly is installed in two adjacent installation spaces, wherein the sorting drive member is installed on one side of the mounting beam, the orthogonal axis reducer 206 is installed at the bottom of the beam, and the pusher claw and the output shaft of the orthogonal axis reducer are matched and located on the other side of the mounting beam. This structure can reduce the distance between adjacent beams, improve the compactness of the structure, and improve the structural strength and rigidity of the actuator mounting bracket. This installation method also maintains the relative independence of the installation space of each component, and each sorting execution assembly does not affect each other.

[0042] Combination Figures 5 to 9 As shown, it is a related structural view of the diversion component, the shaping component and the large-scale dial;

[0043] A shaping bracket is overheadly arranged above the transport device, and the shaping bracket has shaping legs 306 located on both sides of the transport device in the transverse direction, and there are two shaping legs on each side of the transport device in the transverse direction, for a total of four shaping legs, and a shaping mounting frame is fixedly connected to the four shaping legs, and the shaping mounting frame includes a rectangular frame connected to the shaping legs and a longitudinal stereoscopic frame 308 mounted on the rectangular frame 307, and the longitudinal stereoscopic frame 308 is a rectangular parallelepiped frame structure;

[0044] The diverter assembly includes two diverter plates 301 connected to each other and arranged transversely and tilted. The two diverter plates form a triangular structure, and the tip of the diverter assembly is arranged facing the transport direction of the transport device. The transport direction of the transport device is the longitudinal direction. The setting facing the transport direction means that the tip of the diverter assembly is in the opposite direction to the transport direction, so that the coal gangue flow is diverted into two transversely arranged columns facing the tip of the diverter assembly.

[0045] The flow splitter assembly also includes two triangular plates 302 located at the tip of the flow splitter assembly and arranged up and down, and a connecting member 303 fixedly connected between the two triangular plates, the connecting member being a connecting vertical beam, and the heads of the two flow splitters are respectively connected to the oblique sides of the two triangular plates on both sides of the horizontal direction to form a triangular structure. This structure is conducive to strengthening the head of the flow splitter assembly.

[0046] The diverter plate 301 is connected to the shaping mounting frame so as to be installed overhead on the transport device; the shaping frame is connected with an approximately horizontal diverter assembly support beam 304, and the approximately horizontal meaning is that the diverter assembly support beam extends horizontally and allows certain installation and manufacturing errors; the diverter assembly is connected to the diverter assembly support beam, and the diverter assembly support beam is connected to the shaping mounting frame through a diagonal brace 305. One end of the diverter assembly support beam 304 is connected to the longitudinal stereo frame 308, and the other end is connected to the connecting piece 303. One end of the diagonal brace 305 is connected to the diverter assembly support beam 304, and the other end is obliquely connected to the top of the longitudinal stereo frame 308; the tail of the diverter plate 301 is connected to the longitudinal stereo frame 308, and this structure improves the installation stability of the diverter assembly, and strengthens the structural strength and rigidity of the diverter assembly;

[0047] The shaping assembly 400 includes a shaping push plate 401 mounted on a transport device and arranged in a lateral swinging manner, and a shaping drive member that drives the shaping push plate to swing. The two shaping push plates are respectively located on the lateral sides of the diversion assembly. The shaping push plate and the diversion plate are longitudinally staggered. The longitudinal stagger means that the projections of the two in the longitudinal direction do not overlap, which is conducive to the installation of large-scale levers between the two. The shaping push plate 401 and the shaping drive member are installed on the shaping legs. One end of the shaping push plate 401 is hinged to the shaping leg, and the shaping drive member is connected to the other shaping leg on the same side. The output end of the shaping drive member is connected to the outer side of the shaping push plate to push the shaping push plate to swing inward;

[0048] The outer side of the shaping push plate is connected to two angle steels 403 arranged up and down, and the horizontal edges of the two angle steels are arranged back to back. The shaping drive member includes a linear drive member 402 and a U-shaped clamp 404 connected to the end of the linear drive member. A rotating shaft is installed on the U-shaped clamp, and the rotating shaft passes through the horizontal edges of the two angle steels and rotates with the right angle steel. A hole is opened on the right angle steel, and the hole is a waist-shaped hole extending longitudinally to adapt to the position change of the shaping push plate when it swings. The shaping drive member is a cylinder structure, and the shaping push plate is pushed to swing by the extension and contraction of the cylinder output shaft to adjust the coal gangue flow channel between the shaping push plate and the diverter plate;

[0049] The upper and lower edges of the shaping push plate are bent outward to form a protective edge 401a. The protective edge can improve the phenomenon of coal gangue splashing outward and protect the linear drive member 402;

[0050] A large-piece hand 500 is installed above the transport device. The shaping component and the diversion component are staggered longitudinally. The large-piece hand is located in front of the shaping component and behind the diversion component. The large-piece hand is used to move large-particle gangue or coal horizontally out of the transport device. That is, it is ensured that large-particle coal gangue is removed before running to the shaping component. The large-particle gangue here refers to the particle size that exceeds the passing capacity between the diversion component and the shaping component. Gangue or coal gangue of this particle size is pushed out of the transport device to prevent large pieces of gangue and coal from blocking the flow channel between the diversion component and the shaping component, which is conducive to improving the operating stability and reliability of the coal gangue sorting device.

[0051] To make the illustration clear, Figure 8Some parts are hidden in the figure, among which the large-piece shifter 500 includes two large-piece shifting plates 501 which are arranged horizontally and parallelly above the transport device and can swing horizontally, and a large-piece driving component which drives the two large-piece shifting plates to swing, the hinge point of the large-piece shifting plates is located between the two columns of coal gangue flow, and the large-piece shifting plates are located between the shaping component and the diversion component in the longitudinal direction; the large-piece driving component includes a large-piece linear driving component 502 and a middle connecting rod assembly, the middle connecting rod assembly includes a sliding seat 503 and a connecting rod 504 hinged to the sliding seat and the large-piece shifting plates, the large-piece linear driving component 502 drives the sliding seat to slide longitudinally and then drives the large-piece shifting plates to swing horizontally through the connecting rod. The large-piece shifting plate 501 is rotatably mounted on the longitudinal stereoscopic frame 308, wherein a large-piece driving guide rail 505 is also mounted at the bottom of the longitudinal stereoscopic frame 308, and a large-piece linear driving member 502 is a cylinder, which is mounted at the bottom of the longitudinal stereoscopic frame 308. The output end of the longitudinal stereoscopic frame 308 is connected to a sliding seat 503, which is slidably mounted on the large-piece driving guide rail 505. The large-piece driving guide rail 505 is a channel steel or I-beam structure, and the web of the large-piece driving guide rail 505 is horizontally arranged to form a track groove, and a guide wheel 505 is connected to the sliding seat 503. 06, the guide wheel rolls along the web of the large-piece driving guide rail 505, and two connecting rods 504 are hinged on the sliding seat 503, and the other ends of the two connecting rods are respectively hinged with the two large-piece shifting plates 501, that is, the two large-piece shifting plates 501 are synchronously driven to swing outward or inward through the large-piece linear driving member 502. When large particles of coal gangue are found, the two large-piece shifting plates are driven to move simultaneously to push the two columns of coal gangue flow at this position out of the conveying device. Of course, each large-piece shifting plate 501 can be independently provided with a large-piece driving member to realize the independent driving of the two large-piece shifting plates 501, and the details are not repeated here;

[0052] Combination Figure 10 to Figure 11 As shown, it is a related structural view of the small part lever; for the view to be clear, Fig.10 Some of the components in the middle are hidden;

[0053] A small piece shifter 600 is also installed at the tail end of the transport device, and the small piece shifter includes two small piece shifting plates 601 installed above the transport device and arranged in parallel and can swing laterally, and a small piece driving member that drives the two small piece shifting plates to swing. The small piece driving member includes a small piece linear driving member 602 and a middle connecting rod device. The middle connecting rod device includes a sliding seat 603 and a push rod 604 hinged to the sliding seat and the small piece shifting plates. The small piece linear driving member 602 drives the sliding seat to slide longitudinally and then drives the small piece shifting plates to swing laterally through the push rod. The small piece shifting plate 601 is hinged on the actuator mounting bracket, and the small piece linear driving component 602 adopts a cylinder. The small piece linear driving component 602 is connected to the actuator mounting bracket. A guide rail is arranged at the bottom of the actuator mounting bracket, and a roller is connected to the sliding seat 603. The roller rolls along the guide rail. The structure of the small piece shifting hand is similar to that of the large piece shifting hand, and the details are not repeated here. The small pieces of gangue remaining in the coal gangue flow are pushed out of the transportation device through the small piece shifting hand to improve the sorting quality.

[0054] In addition, a guide plate 900 is installed at the tail of the transport device. The guide plate is located behind the small piece pick 600 and is fixed to the actuator mounting bracket. The guide plate is used to guide the sorted coal flow to the corresponding coal storage structure.
