For example, when the elevator 1 is used for excavating coal, the feeder 4 can be used as a coal feeder to uniformly transfer the coal to a belt conveyor, other screening equipment or a storage warehouse.

The dust removing device 5 is used for removing dust in the air inside the vertical lifting machine 1, and is connected with the vertical lifting machine 1 through an air suction channel 28000 arranged on the frame 1000 and/or the housing 10000 and used for removing the dust inside the frame. Suction channel 28000 includes suction tube 28100 and suction inlet 28200.

The discharging chute 11000 and the feeding chute 12000 can be provided with a blocking limit 26000 and a bin wall vibration motor 27000, so that the material feeding and discharging speed is improved.

The working principle of the vertical elevator 1 in this embodiment includes:

according to the principle of tensioning the chain 4000, the chain bucket 5000 vertically moves downwards along with the chain 4000 to the guide chain wheel 8000 and bypasses the tensioning chain wheel 6200; an adjustment driving force is applied to the tensioning adjustment structure 6100, and under the action of the adjustment driving force, the driving end of the tensioning adjustment structure 6100 drives the tensioning sprocket 6200 to move, and further the chain 4000 is tensioned by the tensioning sprocket 6200.

The principle of lifting materials, materials enter a vertical lifting machine 1 from a feeding chute 12000; the opening of the chain bucket 5000 is downward, the chain 4000 starts to wind around the second chain wheel 3000, and in the process that the chain bucket 5000 winds around the second chain wheel 3000, the chain bucket 5000 digs materials into the chain bucket 5000 from the bottom of the rack 1000; after bypassing the second chain wheel 3000, the opening of the chain bucket 5000 is upward, and the loaded materials are lifted to the first chain wheel 2000 along with the chain 4000; after the chain bucket 5000 winds around the first chain wheel 2000 along with the chain 4000, the position and the direction of the chain bucket 5000 are adjusted under the action of the transition chain wheel 9000, so that the opening of the chain bucket 5000 faces the discharging chute 13000, and then materials in the chain bucket 5000 are discharged into the discharging chute 13000 under the action of gravity, and feeding and discharging of the vertical elevator are completed.

The tensioning device 6000 is arranged in the middle of the frame 1000 of the vertical elevator 1, so that tensioning operation of the chain 4000 is achieved, and the problems that the tensioning device of the ultrahigh vertical elevator 1 is difficult to arrange, large in occupied space and difficult in equipment maintenance are solved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present application shall be subject to the appended claims.
