This invention discloses a magnetorheological damper for reducing the piston rod push-out force, relating to the field of magnetorheological damping technology. It includes an outer cylinder and an oil reservoir coaxially sleeved inside the outer cylinder, forming an annular flow channel between the outer cylinder and the oil reservoir. Inside the oil reservoir, from top to bottom, are arranged an upper guide assembly, a piston rod assembly, a shut-off valve assembly, and a floating piston assembly. This invention solves the problem of excessive piston rod push-out force in traditional single-cylinder magnetorheological dampers by placing a shut-off valve assembly in the lower section of the oil reservoir, thus dividing the single working chamber of the traditional single-cylinder magnetorheological damper into three independent chambers: an upper chamber, a lower chamber, and a lower-lower chamber. During compression and extension strokes, the maximum damping force is mainly borne by the shut-off valve assembly, rather than directly acting on the floating piston. This allows the floating piston assembly to only compensate for piston rod volume changes without providing high-pressure support.

This invention relates to the field of conveyor technology and discloses a belt conveyor belt storage bin alignment device, including a mobile trolley. A first mobile support roller is mounted on the mobile trolley, and a first rotating shaft is fixedly connected to the inner surface of the first mobile support roller.

This invention allows for convenient cleaning of dust from the probe surface of the photoelectric sensor without manual operation. It also allows for easy opening and closing of the fan. Furthermore, while the adjusting component controls the fan to stop rotating, it simultaneously drives a protective baffle to move to one side of the fan for shielding, thereby preventing small particles scattered on the conveyor belt from directly impacting or entering the fan when the fan is not in use, thus protecting the fan.
