摘要： PURPOSE:To prevent any stagnation of a conveyed work in a gate part from occurring by making a gate body gp up and a mass through pass through the gate part at a time when the mass body being larger than the specified size mixed in conveyed granular particles comes into contact with a lower end curved part of the gate body. CONSTITUTION:A gate body 2 is set up according to the owing conformed to the position of a hole 2A inserted into an opening adjusting pin 7. Granular particles of petroleum coke and suchlike mounted on a conveyor 1 from the outlet of a hopper H are conveyed downstream through a flow rate regulated by a void in space between a lower end of the gate body 2 and a top face of the conveyor 1 in general. On the other hand, when a large mass body is mixed in the granular particles and it comes into contact with a lower part, this part is curved in the downstream direction. In this case, since a downstream surface is pressed by a presser roller 5, partial pressing force of the mass body works as an upward force of the gate body 2, while the assist force of a balance weight 9 is also added thereto, so that the gate body 2 is pushed upward up to a position where the mass body is passable through. Subsequently, the mass body passes through, the gate body is lowered up to the setting opening again.
