Raw concrete lowering and transporting apparatus
专利汇可以提供Raw concrete lowering and transporting apparatus专利检索，专利查询，专利分析的服务。并且PURPOSE: To prevent separation of concrete and blockade of pipe due to water leak, by making the communication part of a sending-out pipe and the receiving pipe connected with hopper, in free opening and closing, and arranging a water shielding device in the sending-out pipe and continuously feeding necessary amount of proper raw concrete.
CONSTITUTION: A receiving pipe 2 equipped with a hopper 1 at the upper end and a sending-out pipe 4 equipped with a sending-out amount adjuster 3 at the lower end are connected through a communication pipe 6, and the opening 5 of the communication part is made capable of free opening and closing through the head 8 of a cylinder 7, and a water shielding device 9 which blocks the sending-out pipe 4 through fastening the head 8 is arranged. After the opening 5 is blocked by the head 8, and mortar and raw concrete are supplied into the hopper 1, the opening 5 is opened, and raw concrete is sent-out in a prescribed flow rate from the feeding-out amount adjuster 3. When the opening is closed and the head 8 is fastened by the water shielding device 9, and the sending-out pipe 4 is blocked then residual concrete can be prevented from hardening due to dehydration.
