However, after the coal baffle 100 is used for a long time, materials adhere to the coal baffle 100, resulting in an increase in the weight of the coal baffle 100, which causes the problem that the coal baffle 100 is inconvenient to push and pull; in addition, the gap between the clamping groove 140 of the coal baffle 100 and the blanking trough body 300 becomes larger, resulting in the problems of coal scattering or coal leakage.
[0049] In view of this, refer to Figures 2 to 6 , the flip-type coal baffle mechanism provided by the embodiment of the present utility model includes a coal baffle 100 and a connection assembly 200; the connection assembly 200 includes a connection sleeve 210 and a connection shaft 220, the connection sleeve 210 is sleeved on the connection shaft 220, and the connection sleeve 210 is rotationally matched with the connection shaft 220; the coal baffle 100 is connected to the connection shaft 220, and the connection sleeve 210 is used for being installed on the groove side 310 of the blanking trough body 300; or, the coal baffle 100 is connected to the connection sleeve 210, and the connection shaft 220 is used for being connected to the groove side 310 of the blanking trough body 300.

[0051] When the coal baffle 100 is connected to the connecting shaft 220, the connecting sleeve 210 is connected to the chute side 310. During normal use, the bottom of the coal baffle 100 extends into the blanking chute body 300 to achieve the function of blocking coal.
