Claims

[Scope of Utility Model Registration Request] (1) A mechanism for assuring the quality of concrete during transportation, which consists of a concrete mixer truck, in which the input port of the input hopper and the opening of the drum blade are shielded so as to be openable and closable. (2) Concrete quality assurance mechanism during transportation, which controls the input hopper's input port to open and close according to commands from the driver's seat. (3) Concrete quality assurance mechanism during transportation, in which commands to open and close the input port are transmitted by the operator's seat and an external switch mechanism. (4) Claims (1), (2), and (3) in which the input port can be opened and closed by rotating a cover covering the input port in forward and reverse directions about a rotation axis that is a horizontal axis. )
Concrete Quality Assurance Organization during transportation as described. (5) Claims (1), (2), and (3) in which the input port can be opened and closed by rotating the cover that covers the input port in forward and reverse directions about a vertical axis. )
Concrete Quality Assurance Organization during transportation as described. (6) The concrete quality assurance mechanism during transportation according to claim (4), wherein the cover is made of a bellows. (7) The concrete quality assurance mechanism during transportation according to claim (4), wherein the cover is made of cloth. (8) A concrete quality assurance mechanism during transportation as set forth in claims (1), (2), and (3), in which the input port can be opened and closed by an air curtain.
