Description

Technical Field

[0001] The invention belongs to the field of ore bin unloading, and in particular relates to a unloading device. Background Art

[0002] When the open-pit mine bin is unloaded by the swing-type mining machine, dust is easily raised, and the floating mineral dust does not meet environmental protection requirements. For this reason, the mine bin dust removal sprayer is used for dust removal. The dust removal water mist will penetrate into the swing-type mining machine along with the mine bin. Over time, the swing-type mining machine will be severely corroded, and the machine will frequently get stuck, resulting in a high failure rate. Once the machine gets stuck, the top of the machine body, i.e., the discharge port of the mine bin, is easily blocked, resulting in uneven unloading of the mine. In addition, the overhaul and maintenance of the swing-type mining machine after rusting is large, and transportation is difficult. Summary of the invention

[0054] Working principle of the feeding device:

[0055] Reducing the distance between the feeding device and the skirt belt 3 can avoid a large amount of dust, and the skirt of the skirt belt 3 can also avoid a small amount of dust. Therefore, there is no need for a sprayer to remove dust, and the swing-type mining machine will not be mechanically stuck due to rust, resulting in blockage of the ore bin discharge port and uneven material discharge.

[0056] Among them, the driver 741 is started, and the gear transmission 742, the driving roller 73 and the tail roller 71 are driven to rotate in sequence, and the skirt belt 3 also operates accordingly. After being beaten by the beating device, the material in the feeder body 1 enters the skirt belt 3 along the feeding funnel 2 and the unloading channel 31. The operating skirt belt 3 transports the material to the dust cover 5. After reaching the discharge funnel 6, the material falls into the discharge funnel 6. In the process of transporting materials, the deviation adjustment device 8 can correct the transportation direction of the skirt belt 3 in time, that is, the skirt of the skirt belt 3 is in contact with the outer ring of the bearing 83 of the deviation adjustment device 8, and the position of the bearing 83 is fixed. In the process of running the skirt belt 3, the outer ring of the bearing 83 will correct the position of the skirt belt 3 in time.

[0057] If the skirt belt 3 is loose, adjust the tightness of the skirt belt 3 through the tightening device 9. The skirt belt 3 stops operating, removes the screw rod 91 and the support frame 7, and pulls the screw rod 91 outward, so that the slider 93 drives the connecting cover 92 to move, thereby driving the tail roller 71 to move. When the skirt belt 3 is in a taut state, the screw rod 91 and the support frame 7 are connected by a nut to complete the tightness adjustment of the skirt belt 3.

[0058] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
