DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figures 1 to 4 As shown, the utility model provides a coal gangue sorting device, including a device body 1, a first conveyor belt 2, a second conveyor belt 3 and a spreading assembly 10, and also includes a first image recognition device located on the first conveyor belt 2, a second image recognition device located on the second conveyor belt 3, a sorting mechanism and a control system. The first image recognition device, the second image recognition device, the sorting mechanism and the control system adopt conventional means of the prior art (such as the structure disclosed in the publication number CN114833091B), which are not shown in the figure;

[0033] In the above embodiment, the purpose of setting the spreading component 10 is to spread and flatten the coal gangue mixture accumulated after feeding, so that the stacked coal gangue mixture can be quickly separated, avoiding the difficulty of identifying the gangue due to the accumulation or agglomeration of the coal gangue mixture, thereby affecting the sorting effect.

[0034] The evenly spreading assembly 10 is movably connected to the top of the first conveyor belt 2 through a three-axis operating mechanism. Specifically, Figure 4 and Figure 6 As shown, the device body 1 located on both sides of the conveyor belt supports two longitudinal slide rails 4 along the traveling direction of the coal gangue mixture, and a transverse slide rail 5 is horizontally placed above the two longitudinal slide rails 4. The two ends of the transverse slide rail 5 are slidingly connected to the two longitudinal slide rails 4 through an adapter seat 51 and a first slider 52, and are driven by a longitudinal travel motor 7 located at one end of any one of the longitudinal slide rails 4; a second slider 61 is slidingly connected to the transverse slide rail 5 along its track direction (transversely), and one side of the second slider 61 is fixedly connected to an upper and lower slide rail 6, and one side of the upper and lower slide rails 6 is slidingly connected to a sliding connection seat 62, and the evenly spreading component 10 is fixedly connected below the sliding connection seat 62.

[0035] In the above embodiment, if Figures 7 to 10 As shown, the spreading component 10 at least includes a stirring motor 101 and a stirring rod 105 which is transmission-connected to the output shaft of the stirring motor 101, and the stirring rod 105 is staggeredly connected to the output shaft of the stirring motor 101, that is, the two are not on the same spatial axis. When the stirring motor 101 is running, the stirring rod 105 performs circumferential stirring motion around the output shaft of the stirring motor 101; the stirring motor 101 is fixedly connected under the sliding connection seat 62, and its output shaft is vertically facing the first conveyor belt 2.

[0036] The evenly spreading component 10 is movably connected to the top of the first conveyor belt 2 through a three-axis operating mechanism. Specifically, the evenly spreading component 10 drives the sliding connection seat 62 to reciprocate on the upper and lower slide rails 6 through the lifting motor 9 to achieve moving away from or approaching the first conveyor belt 2, drives the second slider 61 to reciprocate along the transverse slide rail 5 through the transverse travel motor 8 to achieve lateral displacement above the first conveyor belt 2, and drives the transverse slide rail 5 to reciprocate on the longitudinal slide rail 4 through the longitudinal travel motor 7 to achieve longitudinal displacement above the first conveyor belt 2; through the above-mentioned longitudinal slide rail 4, transverse slide rail 5 and upper and lower slide rails 6, the evenly spreading component 10 can perform three-axis motion above the first conveyor belt 2 and realize flexible motion in six directions.

[0037] A further optimization scheme is that a turntable 104 is fixedly connected to the output shaft of the stirring motor 101, and the center of the turntable 104 is fixedly connected to the end of the output shaft. At least one stirring rod 105 is fixedly connected to the side of the turntable 104 away from the stirring motor 101, and the fixing position of the stirring rod 105 and the turntable 104 is away from the center of the turntable 104, or in other words, the stirring rod 105 is fixedly connected to a position close to the edge of the turntable 104, so that the stirring rod 105 and the output shaft of the stirring motor 101 are not on the same axis. When the stirring motor 101 is running, the turntable 104 rotates, driving the stirring rod 105 to perform a circular stirring motion.

[0038] In some embodiments, the spreading assembly 10 includes a stirring motor 101, a wiper plate connection seat 102, a wiper plate 103, a rotating disk 104, and a stirring rod 105. The stirring motor 101 is fixedly connected to the wiper plate connection seat 102 below, and the wiper plate 103 is connected to the wiper plate 103 below the wiper plate connection seat 102 through a plurality of elastic connectors. The wiper plate 103 elastically squeezes the coal gangue mixture on the first conveyor belt 2. While the stirring rod 105 is stirring, the spreading assembly 10 is displaced in the horizontal / vertical direction, and the coal gangue mixture is squeezed by the wiper plate 103 and spreads to the surroundings, thereby being able to push away the piled or agglomerated coal gangue mixture.

[0039] It should be understood that the wiper plate connecting seat 102 and the wiper plate 103 have inner holes in their centers for accommodating the stirring rod 105 to pass through, and when the stirring rod 105 performs stirring motion, it will not interfere with the wiper plate connecting seat 102 and the wiper plate 103 .

[0040] According to a further optimized solution, the wiper plate 103 is connected to the wiper plate connecting seat 102 via a plurality of gas springs 106 below.

[0041] According to a further optimized solution, one end of the gas spring 106 is fixedly connected to the wiper plate 103 , and the other end is detachably connected to the bottom of the wiper plate connecting seat 102 .

[0042] A further optimized solution is that a vibrator is provided at the bottom of the first conveyor belt 2, and the vibrator is connected to a vibration motor. The vibrator abuts against the bottom of the first conveyor belt 2 and is driven by the vibration motor to generate vibration. In conjunction with the spreading component 10, the coal gangue mixture on the first conveyor belt 2 can be quickly spread on the first conveyor belt 2.

[0043] In the above embodiment, the purpose of setting the first conveyor belt 2 and the second conveyor belt 3 is to realize the turning of the coal gangue mixture. Therefore, the second conveyor belt 3 is located in front of the first conveyor belt 2 in the direction of travel and is lower than the first conveyor belt 2. Figure 5 As shown, when the coal-gangue mixture falls from the first conveyor belt 2 to the second conveyor belt 3, it rolls and realizes the reverse side, which is convenient for the second image recognition device to perform secondary image recognition on the coal-gangue mixture, so as to more accurately locate each gangue in the coal-gangue mixture, so as to improve the sorting efficiency and sorting accuracy.

[0044] In some embodiments, the running speed of the first conveyor belt 2 is slower, and the running speed of the second conveyor belt 3 is faster than the first conveyor belt 2. The running speed of the first conveyor belt 2 needs to cooperate with the operation of the spreading component 10, so it should not be set too fast; the running speed of the second conveyor belt 3 is set faster than that of the first conveyor belt 2 in order to better spread the coal gangue mixture and facilitate the second image recognition device located above the second conveyor belt 3 to accurately identify the gangue.

[0045] In the above embodiment, if Figure 4 As shown, the first driving shaft 23 and the first driven shaft 24 are rotatably connected at intervals on the device body 1, and the first driving shaft 23 and the first driven shaft 24 drive the first conveyor belt 2 for transmission, and the first driving shaft 23 is connected to the output shaft of the first drive motor 21 through the first belt 22; similarly, the second driving shaft 33 and the second driven shaft 34 are rotatably connected to the device body 1 at intervals, and the second driving shaft 33 and the second driven shaft 34 drive the second conveyor belt 3 for transmission, and the second driving shaft 33 is connected to the output shaft of the second drive motor 31 through the second belt 32.

[0046] It should be understood that, in practical applications, each drive motor may also be other drive structures or mechanical devices capable of realizing linear motion functions / rotational motion / telescopic motion, for example, a servo motor, a hydraulic cylinder, an electric cylinder, and the like.

[0047] The parts not described in detail in the present invention are all conventional technical means known to those skilled in the art.

[0048] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
