Unloading structure of belt conveyor

Abstract

The invention discloses an unloading structure of a belt conveyor. The unloading structure comprises a rack, a conveying belt, an unloading belt and a mounting bracket; the conveying belt is arrangedon the rack; the mounting bracket comprises a mounting part and a connecting rod group; the unloading belt is movably arranged on the periphery of the mounting part in a sleeving manner, the lower endof the unloading belt is matched with the upper surface of the conveying belt, the mounting part is connected with one end of the connecting rod group, and the other end of the connecting rod group is arranged on the rack; and the unloading plane of the unloading belt is inclined to the conveying plane of the conveying belt, and the unloading direction of the unloading belt is inclined to the conveying direction of the conveying belt. The unloading plane and the unloading direction of the unloading belt are respectively inclined to the conveying plane and the conveying direction of the conveying belt, so that stress decomposition of the unloading belt is achieved to generate the line speed, the impact force of materials is decomposed, so that flying dust and spillage are reduced, the rigid friction between the unloading belt and the conveying belt is avoided, the abrasion is reduced, and the service life is prolonged; and the moving speed of the materials in the unloading direction isensured, and the unloading efficiency is improved.

Description

technical field [0001] The invention relates to the field of transmission machinery, in particular to a discharge structure of a belt conveyor. Background technique [0002] Plow unloaders are widely used in belt conveyor systems. The plow unloader adopts the coulter and the belt to achieve rigid pressing contact, and changes the moving direction of the material through the coulter guide, so that the material is plowed into the hopper. Since the coulter is fixed, but the belt and the material are moving, this working mechanism will lead to the following problems: 1. The flow of material has a great impact on the coulter, and the working part of the plow unloader is fully open 2. The coulters wear out quickly and are easy to scratch the belt, which affects the service life; 3. Bring extra load to the rotation of the belt and increase energy consumption; 4. Due to the flow of materials Blocked by coulters, the loss of kinetic energy is relatively large, and when the material...

Since the coulter is fixed, but the belt and the material are moving, this working mechanism will lead to the following problems: 1. The flow of material has a great impact on the coulter, and the working part of the plow unloader is fully open 2. The coulters wear out quickly and are easy to scratch the belt, which affects the service life; 3. Bring extra load to the rotation of the belt and increase energy consumption; 4. Due to the flow of materials Blocked by the coulter, the kinetic energy loss is relatively large, and when the material is wet, it will cause a blockage at the mouth of the hopper
