Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyors, in particular to a scraper conveyor for uniform feeding. Background Art

[0002] Scraper conveyor uses an open chute as a bearing for coal, gangue or materials, and fixes the scraper on a chain (forming a scraper chain) as a traction component. The existing scraper conveyor still has certain defects when in use, such as;

[0003] When a large amount of material is fed into an existing scraper conveyor, the material will basically fill the gap between each two sets of scrapers. When a small amount of material is fed into the conveyor, the amount of material between each two sets of scrapers cannot be controlled, resulting in uneven feeding. In addition, when the scraper of some scraper conveyors is damaged, the disassembly and assembly efficiency is slow, and it is inconvenient to replace the scraper, thus affecting the conveying problem. Utility Model Content

[0004] The utility model aims to provide a scraper conveyor with uniform feeding, so as to solve the problems of uneven feeding and inconvenience in replacing the scrapers of the scraper conveyors currently on the market mentioned in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a scraper conveyor for uniform feeding, comprising: a body, a feeding mechanism, a driving machine and a sprocket;

[0016] Compared with the prior art, the utility model has the following beneficial effects: the controller is operated to set the length of the two-way cylinder activation and the dwell time. When the scraper triggers the proximity sensor, the controller activates the two-way cylinder to drive the sealing plate to move to one side, so that the material in the lower hopper falls into the machine body. Then the two-way cylinder is shortened, driving the sealing plate to reset and block the lower hopper, thereby evenly feeding the material. The inspection door is opened, and then the push rod in the inverted U groove is pushed to the other end of the inverted U groove, the scraper is pushed forward and pulled out, the T-shaped slide plate of the scraper to be replaced is inserted into the T-shaped slide groove, and then the push rod is pushed to reset, and finally the inspection door is closed, so as to facilitate the replacement of the scraper. The specific contents are as follows:

[0017] 1. Operate the controller to set the length of the two-way cylinder start-up and the dwell time to control the amount of material discharged. When the scraper passes the bottom of the proximity sensor, the proximity sensor is triggered. The controller starts the two-way cylinder sealing plate to move to one side, and the material in the hopper falls into the machine body. Then the two-way cylinder drives the sealing plate to reset and block the hopper. Repeat the discharge process. By controlling the discharge amount of the scraper conveyor hopper, the material is quantitatively dropped between the two sets of scrapers in the machine body, and the material is evenly fed.

[0018] 2.

There is no need to use tools such as wrenches, which makes it convenient to replace the scraper conveyor. BRIEF DESCRIPTION OF THE DRAWINGS
