[0032] Refer to Figure 2 Figure 3 The bottom end of feed casing 3 is fixedly connected with the discharge hopper 6, the material can slide down and fall on conveyer belt 2 to transport along the inclined surface of discharge hopper 6 after passing through feed casing 3, the inside of feed casing 3 is fixedly connected with the rotating rod 7, the outside of rotating rod 7 is rotatably connected with the buffer plate 8, the buffer plate 8 can rotate around rotating rod 7, the bottom of buffer plate 8 is provided with a buffer unit, the buffer unit comprises a fixed plate 81, the fixed plate 81 is fixedly connected to the right side surface of feed casing 3, the upper surface of fixed plate 81 is fixedly connected with an elastic member 82, the elastic member 82 comprises a spring and a telescopic rod, the telescopic rod and the spring are fixedly connected to the upper surface of fixed plate 81, the spring is sleeved outside the telescopic rod, can support and limit the spring, avoid the spring to appear to influence the resilience of lateral distortion, the upper end of elastic member 82 and the bottom surface of buffer plate 8 are mutually attached, when buffer plate 8 rotates downward, the elastic member 82 is extruded, so that the elastic member 82 is compressed to generate elastic potential energy.

[0033] The coal mine falls on the buffer plate 8 after passing through the buffer rod 5 and impacts the buffer plate 8, so that the buffer plate 8 rotates downward, at this time, the buffer plate 8 extrudes the elastic member 82 in the rotating process, so that the elastic member 82 is compressed to generate elastic potential energy, buffers and offsets the impact force of the buffer plate 8, thereby reducing the kinetic energy of the part of the material falling on the buffer plate 8, and further reducing the falling speed of the part of the material, then the material will slide down to the discharge hopper 6 on the inclined surface of the buffer plate 8 to discharge, and the other part of the material will directly fall on the discharge hopper 6 to discharge, which can avoid the coal mine material directly falling and impacting on the conveyer belt 2 to affect the structural stability and service life of the conveyer belt 2, the rotating rod 7, the buffer plate 8 and the buffer unit and other structures described above can be staggered and arranged in multiple groups in the inside of feed casing 3, to realize complete buffering of the falling material.

[0034] ​The inner lower side of the feeding shell 3 is fixedly connected with a fixed rod 9, which is located directly below the buffer plate 8. The fixed rod 9 can limit the downward overturning angle of the buffer plate 8, avoid excessive overturning of the buffer plate 8, and cause the compression limit of the elastic element 82 to be exceeded, thereby affecting the use of the elastic element 82. The outer side of the fixed rod 9 is fixedly connected with a rubber sleeve 10, which can avoid hard contact between the buffer plate 8 and the fixed rod 9, thereby avoiding impact and affecting the service life of both.

[0035] The right side surface of the feeding shell 3 is fixedly connected with a baffle 11, the bottom surface of which is in contact with the upper surface of the buffer plate 8. The baffle 11 can shield and protect the upper part of the connection between the buffer plate 8 and the rotating rod 7, avoiding the coal falling directly to the connection, which may cause small particles to be stuck in the connection, affecting the use effect of the buffer plate 8. At the same time, the baffle 11 is inclined as a whole. When the material reaches the baffle 11, it can directly slide down the inclined surface of the baffle 11 to the buffer plate 8, avoiding accumulation on the baffle 11.

[0036] Referring to Figure 1 and Figure 4 , the right side of the feeding shell 3 is provided with a limiting bolt 12, and the right side surface of the feeding shell 3 is fixedly connected with an L-shaped limiting frame 13. The left end of the limiting bolt 12 penetrates the feeding shell 3, and the limiting bolt 12 is threadedly connected with the feeding shell 3. When the limiting bolt 12 is twisted, it can move left and right relative to the feeding shell 3. The inclination of the limiting bolt 12 is the same as that of the buffer plate 8. When the limiting bolt 12 moves to the left, it can move below the buffer plate 8 to limit the buffer plate 8, so that the buffer plate 8 remains stable during cleaning.

The L-shaped limiting frame 13 can limit the rightward movement of the limiting bolt 12 to avoid excessive rightward movement of the limiting bolt 12, causing the limiting bolt 12 to be lost from the feeding shell 3. At the same time, when the limiting bolt 12 comes into contact with the L-shaped limiting frame 13, the limiting bolt 12 is completely away from the buffer plate 8, releasing the limiting of the buffer plate 8, and avoiding the effect of the buffer plate 8 caused by the improper tightening of the limiting bolt 12.

[0038] Working principle: when the coal material is put into the inside of the feeding shell 3, it will first pass through the preliminary shunt of the buffer rod 5 and slow down, then enter the feeding shell 3 downward, and then part of the coal material will fall on the buffer plate 8, extruding the buffer plate 8, so that the buffer plate 8 turns downward around the rotating rod 7, at this time, the buffer plate 8 will extrude the elastic member 82, so that the elastic member 82 is compressed to generate elastic potential energy, buffer and offset the impact force, weaken the kinetic energy of the material, reduce the falling speed of the material, prolong the service life of the discharge hopper 6, finally the material will fall on the discharge hopper 6 and slide along the inclined surface of the discharge hopper 6 to the right side of the conveying belt 2 to complete the transportation, which can avoid the direct falling of the coal mine to the conveying belt 2 to affect the service life of the conveying belt 2, when a large amount of wet coal powder adheres to the buffer plate 8, affecting the use effect, the staff can move the limiting bolt 12 left to the lower side of the buffer plate 8 to limit the buffer plate 8, avoid the downward turning of the buffer plate 8 during cleaning to affect the cleaning efficiency, after cleaning, move the limiting bolt 12 right to remove the limiting, which is simple in operation and simple in structure.
