Abstract

PURPOSE:To control securely discharge of concrete by means of a simple operation by drawing or opening a chute constituted of an elastic tough material connected with a lower section discharge outlet of a concrete bucket. CONSTITUTION:A concrete introducing hole is opened on the side face of a rigid concrete bucket 1 constituted of a metal plate or the like and a closed cap 2 is mounted thereon to be opened and closed freely, closing the inside of the bucket 1 when the same is closed. The lower section of the bucket 1 is inclined in the form of a funnel to flow down the concrete easily, and the same can be equipped with a vibrator or the like appropriately to give vibration to accelerate and help the flowing down and discharging of said concrete. When the chute 3 is closed, the chute 3 is crushed from both sides by revolving a screwed shaft 6, moving the same in the arrow direction and deforming a four- way expanding links device 4 from the solid line state into a flat shape to close the discharge of concrete shown in an imaginary line. The discharge of concrete can be controlled securely and quickly by said process.
