As a kind of transport equipment which works in the closed casing, the trough chain conveyor uses the moving scraper chain to transport the bulk materials continuously. In the closed trough of the trough drag conveyor, the material is transported in the form of continuous material flow that fills the whole section or most sections of the machine groove, and the scraper is completely buried in the material. It is characterized by simple structure, small volume, light quality, good sealing, can be multi - point feeding, multi - point unloading. Trough chain conveyor is one of the important equipment for continuous conveying of bulk materials, but it also has some questions. The problem of grain leakage analysis
The traditional trough chain conveyor does not install the cleaning hopper, it commonly has the seriously problem of material leakage. On the one hand, it is easy to cause scraper and chute surplus mixed grain, bad grain, increase the workload of surplus grain cleaning and waste. Therefore, for a long time, a relatively primitive method has been adopted to isolate and store the surplus grain near the trough chain conveyor with PVC tarp and other materials, and arrange personnel to clean up in time. Some grain enterprises adopt the method of manual cleaning by adding the surplus grain funnel at the tail of the scraper, but personnel need to track and clean the surplus grain at any time.
Solution
In order to solve above questions completely, according to the successful experience of drag chain conveyor surplus grain, a trough type cleaning hopper is added to the chain scraper of the drag chain conveyor to realize the automatic cleaning of surplus grain and completely solve the problem of surplus grain accumulation at the end of the drag chain conveyor. Specific scheme: on both sides of the scraper of drag chain conveyor, the triangular hopper is made by shearing and bending 2.5 ~ 3mm steel plates, which welded on both sides of the scraper to form a cleaning hopper, and the surplus grain is automatically returned to the process or silo in time.
Trough chain conveyor field test to achieve the desired effect, surplus through the trough type cleaning the hopper plate scraping board will be, the head near the tail of surplus automatically and timely pickup to downstream chute flow or silo, completely solve the blow to the rear of the machine head surplus accumulation problem, reduce the surplus grain cleaning work, reduced the dust pollution, made a positive contribution to safety production.
To reform the trough chain conveyor, not only solved the drag chain conveyor without cleaning the hopper of a machine and surplus grain in the slip phenomenon of mixed food, bad food, eliminates the safety hidden trouble, and the next time the warehousing operation is no longer needed someone to clean up of surplus grain, reducing the workload of production operators, all the year round can save costs 1.4 million yuan.
