Concrete mixing car
专利汇可以提供Concrete mixing car专利检索，专利查询，专利分析的服务。并且PURPOSE:To correct a slump value to an adequate value by providing an information processor which detects the number of revolutions of a mixer drum and discriminates the decrease in the number of revolutions when said number decreases as well as a feed means for a fluidizing agent which is driven by the output signal of said processor. CONSTITUTION:A concrete mixing car 1 consists essentially of a mixer drum 2 which is supported rotatably on the body frame of a traveling vehicle, a hydraulically driving device 3 which drives the drum 2, a control device 4, and an information processor 6 which operates selectively a feed means 5 for a fluidizing agent. The processor 6 compares the signal for the number of revolutions from a sensor 26 for measuring the number of revolutions of the drum 2 and the set number of revolutions of the drum 2 set with the device 4, and operates the means 5 when the number of revolutions of the drum 2 decreases lower than the set number of revolutions. The number of revolutions of the drum 2 is made proportional to the discharge quantity from the pump 12.，下面是Concrete mixing car专利的具体信息内容。
