Basin tillage dimming machine control mechanism

The utility model provides a basin tillage dimming machine control mechanism, comprising a long arm (9) of special arrangement and special shape, a short arm (10), a short arm abrasion-proof blocking slice (11), a shifting yoke (5), a tension spring (6), an electromagnetic switch shell (3) and an electromagnetic iron core (4), wherein all the parts are mounted in a closed and detachable box body. The short arm extends outside the box body by a sealing device to control the dimming machine. An electromagnet is used as the power element of the control mechanism and the basin tillage dimming machine is controlled by an electric controller. During the operation process, the control mechanism does not need adjustment and maintenance, the relative position is automatically kept and the drive resistance is small. Only a power supply of a tractor is used to control and drive the control mechanisms on up to 12 dimming units, thus the whole control system is simple and reliable and simultaneously the working frequency
