A high-speed fluidic device has a friction roller type speed-increasing mechanism, an electric motor, and a high-speed fluidic machine, wherein: the friction roller type speed-increasing mechanism includes a housing, a low-speed side member having an outer ring provided at one end portion thereof, a high-speed side shaft rotatably supported by the housing so as to be eccentric to the low-speed side member and the outer ring, at least one guide roller rotatably supported between the outer ring and the high-speed side shaft, and at least one movable roller rotatably supported between the outer ring and the high-speed side shaft; the electric motor drives the friction roller type speed-increasing mechanism; and the high-speed fluidic machine is connected to the high-speed side shaft so as to be driven by the high-speed side shaft.

The invention relates to a garlic combined harvester, which comprises a garlic shoveling system, a garlic pull-out system, a transfer and shear system, a lifting system and a traveling system. The garlic shoveling system includes a main shovel frame, the main shovel frame and an auxiliary shovel blade and a sensor both at the back of the main shovel frame are positioned via a positioning shaft at the front end of the main shovel frame, the rear end of the main shovel frame is connected with an eccentric wheel on the machine frame via a link rod, and an auxiliary shovel blade adjusting device is installed on the main shovel frame. The garlic pull-out system includes a garlic supporting frame located at the front end, the front end of a garlic pull-out frame is located above a shovel blade edge, and the rear end of the garlic pull-out frame is fixed at the upper part of the machine frame. The transfer and shear system includes a garlic bulb push frame fixed on a conveyor chain, a garlic root shear located at the middle part of the conveyor chain, and a garlic stem shear located at the tail part of the conveyor chain. The lifting system adopts hydraulic lifting. The traveling system adopts back driving and steering. The inventive harvester is high in automation degree, time-saving and labor-saving, can cut off garlic roots and stems at one time to complete all garlic harvesting procedures, and is suitable for interplanting land blocks.

A hydraulic controller of a power transmission device is equipped with a transmission for changing a rotation speed of motor power input from a motor and outputting the motor power; a forward / backward change-over mechanism provided between an input shaft, where the motor power of the motor is input and the transmission; and a torque converter having a direct coupling mechanism for transmitting the motor power between an output shaft and the input shaft of the motor; a solenoid valve for adjusting an original pressure and generating a control pressure; and a change-over element for changing over a hydraulic pressure supplied to the forward / backward change-over mechanism so as to become a low pressure during deceleration driving when the direct coupling mechanism is controlled by the solenoid valve, wherein any one of engagement states of the forward / backward change-over mechanism and the direct coupling mechanism is controlled by the control pressure.
