According to the feeding device 100 of the embodiment of the application, materials are received through the pressure reduction guide cone 2, the angle of repose of the receiving bin 1 is reduced, the height of the bin is reduced, the impact of the materials on the receiving bin 1 is dispersed, and the materials are dispersed and equalized in pressure; the stirring component is matched with the decompression guide cone 2, the stirring component is driven to rotate by the driving mechanism, so that the materials are loose and easy to flow, and the materials are discharged from the discharge hole 12 under the driving of the driving mechanism.

A material handling system according to an embodiment of the second aspect of the present application comprises a charging device 100 according to an embodiment of the first aspect of the present application.

In material conveying system, feeding device 100 is located the discharge end of feed bin, connects feed bin 1 to be connected with feed bin detachably, and feed bin exhaust material gets into the feed inlet 11 that connects feed bin 1 to connect the inside flow of feed bin 1, improved the mobility of material, improved the feed bin and for the reinforced efficiency of next process.

It should be noted that the features of the embodiments in the present application may be combined with each other without conflict.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
