Technical Field

The invention relates to the field of constructional engineering, in particular to an automatic discharging system of a finished product bin of plant mixing equipment and a control method.

Background

The existing finished product mixing equipment or material storage bin discharging system adopts a manual button switch mode, and the finished product material door is manually controlled to be opened or closed to discharge materials, so that the existing discharging method has the following defects:

1. the material bin has a single material discharging mode, and when the continuous production is carried out, an operator needs to continuously click the control button by hands, so that the labor intensity of the operator is high. Taking a certain 500 type water stable station as an example: the rated production capacity is 500 tons/hour, if a 50-ton truck is continuously used for loading, 10 trucks are loaded per hour, and one truck is loaded in 6 minutes on average. The finished product bin discharges 3 tons each time, an operator needs to manually click the button switch for 15 times within load minutes, and the manual ringing operation after the car is filled each time is not included, so that the fatigue is easy.

2. Frequent inching of the push-button switch also results in a shortened service life of the switch, increased failure rate and increased maintenance costs. In the aspect of integral use, the working efficiency is reduced, so that workers are tired, and the continuity of construction production is influenced.

3. The device is lack of necessary protection function, easy to operate by mistake and has larger potential safety hazard. Such as: in the continuous production process, the storage bin can overflow due to misoperation, so that a transport vehicle receiving materials is damaged; or operation errors (including errors of drivers of transport vehicles and operators of mixing stations) cause that the transport vehicles entering the station and receiving materials are broken by discharged materials, even hurt people and the like, and dangerous conditions occur.
