Preferably, be provided with the jet-propelled pipeline on directly linking three storehouse bodies, the jet-propelled pipeline passes through solenoid valve intercommunication air supply, and is used for blowing out high-speed air current and blows in directly linking three conveyer pipes with stubborn material and carry out directly linking three storehouse bodies.

Preferably, the bottom side of the cover plate is provided with a circle of backing plate matched with the top opening of the directly-connected three-outlet bin body.

Preferably, a material guide channel is arranged at the material inlet, and a circle of silica gel flange pad is arranged at the top end of the material guide channel.

The invention has the beneficial effects that:

1. the three outlets directly connected with the auger conveying equipment are combined with the gate valve into a whole, so that the installation and processing cost is reduced.

2. The gate valve is obliquely arranged to form a large-angle valve for opening and closing, so that the blanking is facilitated.

3. The former push-pull valve cylinder cavity is directly connected with the three-outlet bin body of the auger conveying equipment for the material brought out by the inserting plate can slide into the three-outlet bin body of the auger conveying equipment, so that the material residue, accumulation and waste are reduced, the convenience of equipment installation is improved, the labor and the time are saved, and the material waste is reduced.
