Problems solved by technology

[0003] But the existing feeding device usually adopts the setting of the feeding tube, so that the material on one group of belt conveyors enters the feeding tube and directly falls on another group of belt conveyors. In the process, the material will directly hit the belt conveyor. Therefore, the long-term impact will accelerate the wear of the belt, thereby reducing the service life of the belt, increasing the maintenance cost of the equipment, and the dust caused by the impact of the falling material will cause environmental pollution. Therefore, the present invention proposes a screw-type air-lock feeding device To solve the problems existing in the prior art

Abstract

The invention provides a spiral air locking type feeding device. The device comprises a bearing frame body and a belt conveyor, the belt conveyor is arranged below the bearing frame body, an opening is formed in the bearing frame body, a concentric-square-shaped bearing plate is arranged below the opening, the outer side of the concentric-square-shaped bearing plate is connected with the bearing frame body, a material guiding barrel is arranged in the concentric-square-shaped bearing plate, the lower end of the material guiding barrel is provided with a material conveying auger, the material conveying auger is provided with a first feeding port, the first feeding port is connected with the material guiding barrel, the output end of the material conveying auger is provided with a material guiding groove, and the outer side of the material guiding barrel is provided with an annular limiting plate. According to the spiral air locking type feeding device, the material conveying auger is arranged below the material guiding barrel, the material guiding barrel is slidably connected with a bearing suspender through a spring, and when materials are conveyed, the buffering effect is achieved through cooperation of the material conveying auger and the spring, so that damage to a belt is reduced, the service life of the belt is prolonged, and the equipment maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of conveying and feeding equipment, in particular to a screw air-locking feeding device. Background technique [0002] The screw air-lock feeding device belongs to a kind of screw feeding device, which is usually applied to various industrial equipment to complete material conveying operations. For example, in mine operations, it is often necessary to carry out ore and steel in the mine. Conveying, and in the process of conveying, due to the long conveying distance, it needs to be transferred, and during the transfer, it is necessary to complete the transfer operation through the drop hopper for subsequent conveying; [0003] But the existing feeding device usually adopts the setting of the feeding tube, so that the material on one group of belt conveyors enters the feeding tube and directly falls on another group of belt conveyors. In the process, the material will directly hit the belt conveyor. Therefore...
