[0019] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a fully enclosed device of a transfer machine of the present utility model with reference to the accompanying drawings.

[0020] Such as Figures 1 to 3As shown in the figure, a fully enclosed device for a transfer machine is provided at the tail of the transfer machine 1. The transfer machine 1 is a scraper transfer machine for the gate road. The tail of the transfer machine 1 is lapped with a side-discharge scraper conveyor 2. The fully enclosed device for the transfer machine includes a back baffle 3, a side baffle 4 and a cover plate 5 which are connected to each other and arranged on the back side, end side and above of the transfer machine 1. The back baffle 3 and the side baffle 4 are fixed on the transfer machine 1. A strip-shaped support steel beam 6 is arranged on the unloading end side of the transfer machine 1 to support and fix the cantilever angle of the cover plate 5. One end of the cover plate 5 facing the unloading end side is suspended with vertical chains 7 at intervals. One end of a horizontal chain 8 is fixed to the end side of the side baffle 4 facing the unloading end side and the side end of the support steel beam 6. The vertical chains 7 and the horizontal chain 8 form a chain net to enclose the unloading end side of the transfer machine. Strip-shaped holes are arranged at intervals on the side baffle 4 and the cover plate 5. The strip-shaped holes arranged on the side baffle 4 are observation holes, through which the internal situation of the transfer machine can be observed at the tail of the machine. The strip-shaped holes on the cover plate 5 can receive the coal falling from above and directly convey it away along the transfer machine. A spraying mechanism 9 is arranged on the cover plate 5. The nozzles arranged by the spraying mechanism 9 extend into the fully enclosed device through the strip-shaped holes to achieve the purpose of dust reduction at the head of the working face.

[0021] Discharge section baffles 11 are arranged on both the unloading end side and the back side of the transfer machine 1. The upper side end of the discharge section baffle 11 is higher than the conveying trough of the transfer machine. One side end of the discharge section baffle 11 is connected to the side baffle 4.
