The present application relates to a kind of damping mechanism and grinding polishing machine tool, damping mechanism includes fixed seat, connecting disc and at least two piston cylinders, piston cylinder includes piston rod, fixed seat is used to connect, at least two piston cylinders are arranged in pairs on connecting disc, closed fluid circuit is arranged between each pair of piston cylinders, fixed seat is movably connected with connecting disc by piston cylinder, piston cylinder is arranged to damp the movement of fixed seat.Grounding, grinding disc will be lifted by the part of workpiece thickness, will produce floating and drive fixed seat floating in rotation process, piston cylinder is provided with throttle orifice at the connection of the side of fluid circuit away from fixed seat, due to the throttle effect of small hole, pressure difference can be generated on both sides of throttle orifice, and then pressure difference is generated between each pair of piston cylinders, so that the part of workpiece thickness bears larger pressure from grinding disc.Each two piston cylinders are arranged in pairs on connecting disc, and pressure is applied to each part of workpiece, so as to improve grinding efficiency.

The utility model discloses a geological sample grinding and screening integrated equipment relates to geological sample detection technical field. Including work table, the work table top central part is provided with grinding mechanism, and grinding mechanism contains jar body, and the connection between jar body and work table, the jar body bottom central rotation is connected with rotating shaft, and rotating shaft outer wall fixedly connected with a plurality of equidistance connecting plates, and the one side of connecting plate rotatable connection has a plurality of equidistance grinding block, and the one side of connecting plate rotatable connection has first filter plate. The utility model discloses through the setting of grinding mechanism and filter mechanism, in the use process, first geological sample passes into the jar body through the feed pipe, then motor drive rotating shaft rotation drives connecting plate and grinding block rotation, and the sample on first filter plate is ground, and the particle size is smaller and enters the next layer and continues to grind, and the device can effectively reduce the grinding length, and improve the work efficiency through multistage grinding.

The application discloses a preparation device and method of tea stock solution, and relates to the technical field of tea stock solution production. The device comprises a grinding mechanism, an upper grinding disc and a lower grinding disc are arranged in a grinding box body of the grinding mechanism, the lower grinding disc is driven by a driving mechanism to rotate oppositely with the upper grinding disc, an adjusting mechanism for adjusting the distance between the upper grinding disc and the lower grinding disc is further arranged on the grinding box body, and the device further comprises an extension part, which comprises an upper extension body for extending the radial dimension of the upper grinding disc and a lower extension body for extending the radial dimension of the lower grinding disc; a pushing piece for controlling the extension of the upper extension body and the lower extension body is further arranged; a monitoring mechanism is arranged for monitoring the granularity of tea leaves; the adjusting mechanism adjusts the distance between the upper grinding disc and the lower grinding disc in real time based on the monitoring signal of the monitoring mechanism; and the pushing piece controls the extension dimension of the upper extension body and the lower extension body based on the power of the adjusting mechanism.
