Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a mineral sorting device includes a machine body 1. The inner surface of the machine body 1 is fixedly connected with a first screening frame 2. The inner surface of the machine body 1 is fixedly connected with a second screening frame 3 below the first screening frame 2. Three crushing assemblies 5 are rotatably connected inside the machine body 1. The crushing assembly 5 includes a mounting disc 6, a mounting seat 7, an extrusion disc 8 and an outer cylinder 9. The inner surface of the machine body 1 is fixedly connected with a mounting disc 6. The side surface of the mounting disc 6 is embedded and rotatably connected with a rotating cylinder 601. The outer surface of the rotating cylinder 601 is fixedly connected with a limiting sleeve 603. The inner surface of the rotating cylinder 601 is rotatably connected with a threaded column 602.

A plurality of extrusion discs 8 are slidably connected to the outer surface of the limiting sleeve 603. The outer surface of the mounting seat 7 is detachably connected with an outer cylinder 9.

[0023] Specifically, when in use, minerals are put into the opening position above the machine body 1. The three crushing assemblies 5 crush the minerals. The crushed minerals fall onto the arc board 103 and fall into the first screening frame 2 through the through groove 104. After being screened by the first screening frame 2, they fall onto the second screening frame 3, thus completing the classification and screening operation.

[0024] Embodiment 1

[0025] As Figures 1 - 4 shown, the front surface of the machine body 1 is rotatably connected with a maintenance door 101. The inner surface of the machine body 1 is fixedly connected with a slope rack board 102. The inner surface of the machine body 1 is fixedly connected with an arc board 103. The upper surface of the arc board 103 is provided with a through groove 104. The upper surface of the arc board 103 is fixedly connected with a second crushing knife 105.

[0026] In this embodiment, by opening the maintenance door 101, the crushing assembly 5 can be maintained from the front side of the device. The arc plate 103 is used to carry the pre-crushed minerals, and the second crushing knife 105 cooperates with the crushing assembly 5 to perform secondary crushing on the minerals.

[0027] As Figures 1 - 4 shown, a speed reducer 4 is fixedly connected to the outer surface of the machine body 1. A stepping motor 401 is fixedly connected to the upper surface of the speed reducer 4. The output end of the stepping motor 401 is fixedly connected to the output end of the speed reducer 4, and the output end of the speed reducer 4 is fixedly connected to the rotating cylinder 601.

[0028] In this embodiment, when the stepping motor 401 is started, the stepping motor 401 cooperates with the speed reducer 4 to drive the rotating cylinder 601 to rotate. The rotating cylinder 601 drives the limit sleeve 603 to rotate, further driving the mounting seat 7, the extrusion disc 8, the outer cylinder 9, and the first crushing knife 901 to rotate, so as to crush the minerals by the first crushing knife 901 moving in a circular motion.

[0029] Embodiment Two

[0030] On the basis of Embodiment One, in order to make up for the problem that it is inconvenient to disassemble a single first crushing knife 901 in Embodiment One.

[0031] As Figures 1 - 4 shown, a mounting frame 701 is fixedly connected to the side surface of the mounting seat 7, and a fixing bolt 702 is threadedly connected to the outer surface of the mounting seat 7.

[0032] In this embodiment, the outer cylinder 9, the mounting seat 7, and the mounting disc 6 are fixedly connected by the fixing bolt 702.

[0033] As Figures 1 - 4 shown, a sleeve 801 is fixedly connected to the side surface of the extrusion disc 8. A spring 802 is placed inside the sleeve 801. A push rod 803 is movably connected inside the sleeve 801. The end of the push rod 803 is fixedly connected to a limit block 804. The limit block 804 is inserted into the mounting frame 701. The first crushing knife 901 is embedded and connected to the outer surface of the outer cylinder 9. The first crushing knife 901 is slidably connected to the mounting frame 701. The extrusion disc 8 is threadedly connected to the threaded column 602.

[0034] In this embodiment, when disassembling the first crushing knife 901, an external tool is used to rotate the threaded column 602 inside the rotating cylinder 601 alone. At this time, under the push of the thread, the pressing disc 8 moves away from the mounting seat 7. At this time, under the push of the spring 802, the pressing rod 803 presses the limiting block 804, so that the limiting block 804 pushes the first crushing knife 901 into contact with the mounting frame 701. At this time, manually slide the first crushing knife 901 along the mounting frame 701 to separate the first crushing knife 901 from the mounting frame 701, and then the first crushing knife 901 can be taken out. The other first crushing knives 901 are assisted and limited by the limiting block 804, which is convenient for later maintenance of the first crushing knife 901.
