Abstract: - 44 The controller of the mixer drum washing apparatus controls the driving device so that the rotational speed of the mixer drum changes according to the target washing pattern in which the target rotational speed of the mixer drum at the time of washing is set. The target rotational speed of the mixer drum of the target washing pattern is set so as to increase to the charging-side washing rotational speed DN1 and the discharging-side washing rotational speed DN2 at a predetermined time change rate, or to decrease from the charging-side washing rotational speed DN1 and the discharging-side washing rotational speed DN2 at a predetermined time change rate. 0o C%4 C'%D

Abstract: Provided is a manufacturing apparatus or a transporting apparatus capable of satisfactorily manufacturing ready-mixed concrete. A concrete mixer truck (1) includes a mixing drum (20), a hydraulic motor (40), a hydraulic pump (50), an engine (60), a pressure sensor (70), and a control device (80). The hydraulic motor (40) is a two-speed type and rotates the mixing drum (20). The pressure sensor (70) detects a driving pressure of the hydraulic motor (40). When the pressure sensor (70) detects a pressure value less than or equal to a first pressure value, the control device (80) performs a first rotation step of driving the engine (60) at a first rotational speed while putting the hydraulic motor (40) into a second speed to rotate the mixing drum. In addition, when the pressure sensor (70) detects a pressure value greater than the first pressure value, the control device (80) performs a second rotation step of driving the engine (60) at a second rotational speed higher than the first rotational speed while putting the hydraulic motor (40) into a first speed to rotate the mixing drum.

Abstract: Provided is a mixer vehicle capable of preventing ready-mixed concrete from spilling out from an opening of a mixer drum when driving up an ascending slope. A vehicle body (10) includes a mount (13). A mixer drum (20) has an opening (27) that opens to the rear end, and is rotatably mounted on the mount (13) in a forward-tilted orientation. The mixer drum (20) includes a helical drum blade (25) fixed to the inner wall surface thereof, and when the mixer drum (20) is subjected to positive rotation, ready-mixed concrete introduced therein is moved forward by the drum blade (25). A rotating device (40) causes the mixer drum (20) to rotate. An angle acquisition device (50) acquires the inclination angle of the mount (13) in the front-to-rear direction. When the inclination angle acquired by the angle acquisition device (50) becomes greater than or equal to a predetermined angle in a state where the mount (13) is in a downwardly inclined state from the front end toward the rear, a control device (70) executes a sloping road control by which the rotating device (40) increases the rotation speed of the positive rotation of the mixer drum (20).

Abstract: Providing a ready-mixed concrete manufacturing apparatus or transporting apparatus which can successfully manufacture ready-mixed concrete by adjusting rotational velocity to compensate for changes in viscosity etc of the concrete mixture as it is being mixed, thereby evening the load on the mixing motor. A mixer vehicle (1) includes a mixing drum (20), a hydraulic motor (40), a hydraulic pump (50), an engine (60), a pressure sensor (70), and a control device (80). The hydraulic motor (40) is of a two-speed type and rotates the mixing drum (20). The pressure sensor (70) detects driving pressure of the hydraulic motor (40). When the pressure sensor (70) detects a pressure value of not more than a first pressure value, the control device (80) executes a first rotation process in which the engine (60) is driven at a first rotational speed while the hydraulic motor (40) is put in a second gear to rotate the mixing drum (20). When the pressure sensor (70) detects a pressure value larger than the first pressure value, the control device executes a second rotation process in which the engine (60) is driven at a second rotational speed higher than the first rotational speed while the hydraulic motor (40) is put in a first gear to rotate the mixing drum (20).
