[0037] In one embodiment, the transfer chute 100 also includes a second buffer mechanism 3, the second buffer mechanism 3 includes a third buffer plate 31 and a fourth buffer plate 32, the third buffer plate 31 and the fourth buffer plate 32 are both connected to the inner wall of the chute 1, and the third buffer plate 31 is arranged toward the first diversion channel 26, and the fourth buffer plate 32 is arranged toward the second diversion channel 27, the third buffer plate 31 and the fourth buffer plate 32 are both inclined, the third buffer plate 31, the fourth buffer plate 32 and the inner wall of the chute 1 are surrounded to form a third channel 33, the third channel 33 is located above the first discharge port 13 and is arranged close to the first discharge port 13, the two ends of the third channel 33 are respectively connected to the second channel 112 and the first discharge port 13, and the inner diameter of the third channel 33 is gradually reduced in the direction close to the first discharge port 13; specifically, in order to better alleviate the impact force of the lump coal material flow during the transfer process and reduce the crushing rate of the lump coal, in this embodiment In the transfer chute 100, the transfer chute 100 also includes a second buffer mechanism 3. By setting a third buffer plate 31 and a fourth buffer plate 32, the lump coal material flow in the first diversion channel 26 passes through the second channel 112 and then hits the third buffer plate 31, and the lump coal material flow in the second diversion channel 27 passes through the second channel 112 and then hits the fourth buffer plate 32. Since the third buffer plate 31 and the fourth buffer plate 32 are both inclined, the two sections of lump coal material flow are respectively combined into a lump coal material flow along the third channel 33 under the action of the third buffer plate 31 and the fourth buffer plate 32, and flow out from the first discharge port 13, so that the lump coal material flow can again achieve the effect of reducing the falling speed and alleviating the falling impact, which can further reduce the breakage rate of the lump coal, improve the quality of the lump coal, and enhance the economy of the lump coal; and by setting the second buffer mechanism 3, the impact force on the discharge material conveyor can also be reduced, effectively extending the service life of the discharge material conveyor.
[0038] In one embodiment, the third buffer plate 31 includes a third plate body 311 and a third elastic reset member 312, and the fourth buffer plate 32 includes a fourth plate body 321 and a fourth elastic reset member 322.

The third plate body 311, the fourth plate body 321 and the inner wall of the chute 1 are enclosed to form a third channel 33. Specifically, in order to enable the second buffer mechanism 3 to have a better buffering effect on the lump coal material flow, in this embodiment, the third elastic reset member 312 is used to assist the third plate body 311 in resetting when it rotates after being impacted by the lump coal material flow in the first diversion channel 26. The elastic reset member 322 is used to assist the fourth plate body 321 in resetting after being impacted by the coal block flow in the second diversion channel 27 and rotating. The potential energy of the two coal block flows is used to impact the third plate body 311 and the fourth plate body 321 respectively, so that the third plate body 311 and the fourth plate body 321 rotate relative to the chute 1. However, due to the action of the third elastic reset member 312 and the fourth elastic reset member 322, the third plate body 311 and the fourth plate body 321 are reset, thereby having a better buffering effect on the coal block flow, so as to reduce the falling speed and impact force of the coal blocks, and better reduce the breakage rate of the coal blocks; and the third plate body 311 and the fourth plate body 321 will continue to vibrate as the coal block flow continues to fall, so that the coal block flow falls evenly, and when sliding downward through the third channel 33, a uniformly distributed impact force is generated on the material conveyor below, thereby avoiding fatigue damage to the material conveyor.
