Bottom-top throwing multi-point discharging belt conveyor

Abstract

The invention discloses a lifting parabola type multipoint discharging belt type conveyor composed of a transportation section, a lifting discharging section with a front part which can rise and fall, a driving section and a back section sequentially connected into a closed loop. A lifter is installed below the lifting discharging section; when the lifting discharging section rises, a parabola discharging angle is formed with a return pulley, and transported materials are discharged in parabolic path; a parabola feed channel is arranged above the front of a parabola roller; a bidirectional gate valve is installed at the lower part inside the parabola feed channel for switching and controlling two elephant trunks; materials reach different positions through different discharging elephant trunks. A plurality of lifting discharging sections and parabola feed channels can be installed on the belt type conveyor so as to realize multipoint discharging. The device avoids the accidents, such as mixed material, and the like, has simple structure, low error rate, less maintenance cost and small occupied space, can adopt a sealing mechanism to be suitably applied to outdoor work; the device can be designed to be wholly combined with other belt conveyors to adapted to different work environments and work conditions.

Description

technical field [0001] The invention belongs to the field of belt conveying equipment, in particular to an elevation parabolic multi-point unloading belt conveyer. Background technique [0002] At present, the common multi-point unloading devices are mainly fixed plow unloaders and mobile unloading trolleys. The advantages of the plow unloader are compact structure, simple operation, and convenient transportation of the same material. The disadvantage is that the unloading plow is easy to wear, and a small amount of fine-grained material can sometimes fall from the contact gap between the unloading plow and the conveyor belt to the head unloading point for discharge, which is prone to mixing accidents; the unloading plow has a negative impact on the life of the conveyor belt. Great impact, the coulter often scratches the conveyor belt; the contact gap between the unloading plow and the conveyor belt is difficult to control, and the coulter needs to be replaced regularly, an...

Problems solved by technology

The disadvantage is that due to the control of the baffle valve, once the baffle valve fails, it is easy to cause a mixing accident; in addition, when the conveyor head is unloading, the material must pass through all the unloading devices, and the material must pass through the chute and valve many times. It is easy to cause material damage and wear; the material passes through the unloading device for many times, and it is easy to generate a large amount of dust, so the requirements for the dust removal system are relatively high; due to multiple unloading, it will inevitably cause wear and tear on the discharge chute, baffle valve and other components, increasing Maintenance workload
