Therefore, the following specific implementation methods and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction on the technical solution of the utility model.

[0033] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different positions and different usage conditions.

[0034] The material sorting mechanism provided by the utility model is mainly used in a coal gangue sorting system. The material sorting mechanism is arranged at the end of a material conveying belt of the coal gangue sorting system and is used to sort identified target materials. The target material referred to in the utility model is coal gangue.

[0035] like Figure 1-Figure 3 As shown, a material sorting mechanism 10 provided by an embodiment of the utility model includes a fixed frame 11, a striking assembly 12 for ejecting target materials, and a material collecting device 13. The striking assembly 12 is arranged on the top of the fixed frame 11, and the material collecting device 13 is arranged on the bottom of the fixed frame 11 and covers the ejection range of the striking assembly 12.

[0036] The material sorting mechanism 10 provided in this embodiment mainly includes a fixing frame 11 , a striking assembly 12 and a material collecting device 13 .

[0037] The fixing frame 11 is used to fix the striking assembly 12 and the material collecting device 13 .

[0038] The impact assembly 12 is arranged on the top of the fixing frame 11. The impact assembly 12 is used to eject the target material. When installed and used, the impact assembly 12 ejects the target material toward the discharge port of the material conveyor belt. When the material sorting system identifies the gangue, the impact assembly 12 ejects the gangue, changes the movement trajectory of the gangue, thereby sorting out the gangue and improving the quality of the coal block.

[0039] The material collecting device 13 is arranged at the bottom of the fixed frame 11, and the material collecting device 13 covers the ejection range of the impact component 12. The material collecting device 13 is used to collect the target material ejected by the impact component 12. When it is necessary to collect fine material (such as fine coal), the material collecting device 13 can be divided into a target material collection area and a fine material collection area in a partitioned form.

[0040] Among them, the material sorting system can use existing technology to identify the coal gangue on the material conveyor belt. The specific identification method does not belong to the improvement point of this application and will not be described here.

[0041] The top and bottom referred to in this embodiment are relative to the ground. During installation, the side away from the ground is the top, and the side close to the ground is the bottom.

[0042] In this embodiment, a fixed frame, a striking assembly and a material collecting device are set, and the striking assembly is set on the top of the fixed frame, and the material collecting device is set at the bottom of the fixed frame. When the target material is identified, the striking assembly ejects the target material to the material collecting device, and changes the movement trajectory of the target material, thereby quickly sorting out the target material. It can be suitable for target materials of different sizes, will not generate noise and pollution, and will not cause safety accidents such as coal dust explosions, and has high safety.

[0043] In one embodiment, if Figure 2 As shown, the impact assembly 12 includes a plurality of impactors 121, each of which includes an electromagnet 1211, a impact rod 1212 and an elastic member 1213. The electromagnet 1211 is provided with a through hole penetrating the electromagnet 1211 and a terminal 1214 electrically connected to a power source;

[0044] One end of the impact rod 1212 is connected to the elastic member 1213, and the other end of the impact rod 1212 passes through the through hole, so that the impact rod 1212 and the electromagnet 1211 are in clearance fit;

[0045] The electromagnet 1211 includes a power-on state and a power-off state. When the electromagnet 1211 is in the power-on state, the other end of the impact rod 1212 moves in a direction away from the elastic member 1213; when the electromagnet 1211 is in the power-off state, the other end of the impact rod 1212 moves in a direction toward the elastic member 1213.

[0046] The impact assembly 12 includes a plurality of impactors 121. When installed, the plurality of impactors 121 are evenly distributed along the width direction of the material discharge port of the material conveyor belt and cover the material discharge port.

[0047] Each ejector 121 includes an electromagnet 1211, an ejection rod 1212 and an elastic member 1213. A terminal 1214 is provided on the electromagnet 1211. When a target material is identified, the terminal 1214 is energized to cause the electromagnet 1211 to generate a magnetic force. When the magnetic force is greater than the elastic force of the elastic member 1213, the ejection rod 1212 is driven to eject in a direction away from the elastic member 1213, changing the movement trajectory of the target material, thereby ejecting the target material. When the target material is ejected, the terminal 1214 is de-energized, the electromagnet 1211 loses its magnetic force, and the elastic force of the elastic member 1213 drives the ejection rod 1212 to retract in a direction close to the elastic member 1213, thereby resetting the ejection member 1212.

[0048] Preferably, the number of the ejectors 121 is 96. Figure 3 As shown, 96 ejectors 121 form a first layer ejector group and a second layer ejector group which are arranged in sequence from top to bottom, and the first layer ejector group and the second layer ejector group are alternately distributed.

[0053] The impact assembly 12 also includes a relay and a relay card. The relay is used to control the connection or disconnection between the terminal 1214 and the power supply. The number of relays corresponds to the number of impactors 121. Each relay corresponds to a impactor 121. Each relay is provided with an identification code. When the target material is identified, the identification code is used to automatically control the opening or closing of the relay. When in use, the identification code of the relay and the impactor number can be stored in the controller in the following table:

[0054] Tap number Relay identification code i <![CDATA[A i ]]>

[0055] The number of the ejector is the sequence number of ejector 121, such as Figure 3 As shown, they are numbered 1-96 from top to bottom.

[0056] Preferably, the number of relays is 96.

[0057] The relay board is used to control the opening or closing of the relay. Each relay board can control 32 relays, so the number of relay boards is 3. The relay board can be built into the controller. When in use, the relay board receives the control command of the controller and controls the opening or closing of the relay according to the control command. It should be noted that the specific structure and working principle of the relay and the relay board can be implemented using existing technologies and will not be described in detail here.

[0060] In one embodiment, a partition plate 133 is disposed between the target material conveyor belt 131 and the fine material conveyor belt 132 to prevent the target material from being mixed with the fine material.
