Automatic material receiving and discharging device of belt conveyor

Abstract

The device is applied to belt conveyor lifting and transporting equipment of industrial and mining enterprises, can automatically receive scattered materials when the materials are scattered, and can semi-automatically pour the scattered materials onto a belt conveyor. According to the design, an advanced hydraulic operating system technology is adopted, a plurality of groups of hydraulic jacks are designed on the structure to control the left-right and up-down movement of the material receiving groove, the position of the material receiving groove can be accurately controlled, and when materials are scattered from the conveying belt due to deviation or other reasons, the scattered materials are automatically received; and after the materials are fully received, the received materials are put on the conveying belt again to be conveyed, so that the materials scattered on the ground from the conveying belt are reduced, and the labor intensity of manually cleaning the scattered materials is reduced. At present, no similar device for cleaning the scattered materials for the belt conveyor exists on the market, so that the design creates the technical precedent in the field.

Description

1. Technical Field

[0001] The patent of this invention is applied to the field of belt conveyor transportation technology in industrial and mining enterprises. 2. Background Technology

[0002] At present, belt conveyors are widely used in coal mines or other industrial and mining enterprises. Belt conveyors are mainly composed of three parts: the head unloading drive part, the middle part and the tail part. A closed loop conveyor belt from the head to the tail is used to transport materials from the tail to the head. When the belt conveyor transports materials, materials often fall due to the deviation of the conveyor belt. When the materials fall seriously, the belt conveyor line is often filled with materials and needs to be cleaned manually with a shovel, which puts a great burden on the workload of the belt conveyor operation and maintenance personnel. III. Summary of the invention

[0003] In order to reduce the labor intensity of personnel manually cleaning up materials when materials are spilled on a belt conveyor during material transportation, the present invention designs an automatic material receiving and unloading device, which automatically receives the spilled materials when materials are spilled from the conveyor belt due to deviation of the conveyor belt or other reasons, and puts the received materials back onto the conveyor belt for transportation, thereby reducing the materials spilled from the conveyor belt to the ground, thereby reducing the labor intensity of personnel manually cleaning up the spilled materials.

[0004] 4. Technical issues to be solved

[0005] Currently, there is no automatic material receiving and unloading device of this type on the market. The present invention pioneers the transformation of manual material receiving and unloading into a mechanical and automated material receiving and unloading method. A set of material receiving troughs are installed on both sides of the belt conveyor and fixed to a support frame. The material receiving troughs are driven by the hydraulic system to move up, down, left, and right to the top of the conveyor belt to realize the function of automatic unloading.

[0006] V. Technical Solution

[0007] The present invention designs a set of automatic material receiving and unloading device, 2 12# channel steels are laid on the bottom floor of one side of the belt conveyor, a group of support frames of the 12# channel steel are inserted into the upper part of the channel steel, a hydraulic jack is installed between the support frames, and the support frame is moved forward and pushed backward on the track by operating the jack (hereinafter referred to as the horizontal jack) to extend and retract, and a hydraulic jack (hereinafter referred to as the vertical jack) is added between the horizontal braces on the upper part of the 12# channel steel, and the other end of the jack is fixed to the material receiving trough welded with the steel plate, and the up and down lifting of the material receiving trough is controlled by operating the hydraulic jack. Under normal circumstances, the material receiving trough is located below the conveyor belt of the belt conveyor. When the conveyor belt is scattered with materials, the material receiving trough receives the scattered materials. After the materials are filled, the personnel operate the vertical jack to raise the material receiving trough to the top of the conveyor belt, and then operate the jack fixed with the steel plate of the material receiving trough (hereinafter referred to as the push jack) to push the materials onto the conveyor belt to realize the automatic completion function of material receiving and unloading. The device also needs to be equipped with a hydraulic pump station to support a multi-way hydraulic control valve group for controlling the opening and closing of each hydraulic jack.

[0008] VI. Beneficial Effects

[0009] The present invention utilizes the existing advanced hydraulic system technology to achieve semi-automatic control of the reception and unloading of materials scattered from the conveyor belt, avoiding the time-consuming and laborious operation of manually using a shovel to clean up the scattered materials. Personnel only need to operate the hydraulic control valve group to control the opening and closing of each hydraulic jack to control the forward movement and backward push of the material receiving chute to rise and fall, thereby achieving precise position control of the material receiving chute and completing automatic material receiving and unloading operations, avoiding the traditional operation method of manually using a shovel to clean up the scattered materials from the belt conveyor, and greatly reducing the labor intensity of operation and maintenance personnel. VII. Description of the Figures

[0010] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0011] Figure 1 It is a schematic diagram of the overall equipment installation of the patent of this invention. Channel steel support frames are installed on both sides of the belt conveyor. The support frames are located on channel steel slide rails. Two horizontal jacks are installed on the channel steel slide rails and connected to the support frames. Vertical jacks and springs are installed on the support frames and welded and fixed to the material receiving trough. A push jack and spring are installed on the material receiving trough made of steel plates.

[0012] Figure 2 This is the patented channel steel slide rail base diagram of the present invention. A set of channel steel slide rail bases are installed on both sides of the belt conveyor. The channel steel slide rail base is composed of a channel steel slide rail, a horizontal jack and a channel steel support frame.
