This utility model discloses a trimming and cutting device for particleboard production, including a U-shaped bottom hollow frame, sponge rollers rotatably mounted at the front and rear positions inside the U-shaped bottom hollow frame via bearing seats, a drive shaft rotatably mounted on one inner wall of the U-shaped bottom hollow frame, and an external spline shaft rotatably mounted on the inner wall of the U-shaped bottom hollow frame below the drive shaft. A left cutting disc is fixed to one end of the external spline shaft near the inner wall of the U-shaped bottom hollow frame. A three-gear speed-increasing transmission structure is installed between the drive shaft and the external spline shaft. This utility model controls the positions of the L-shaped shaft carrier, T-shaped hollow bushing, internal spline shaft, and right cutting disc via a control panel and an X-axis lead screw electric module. After adjustment, the motor transmits power to the external spline shaft and internal spline shaft, causing the left and right cutting discs to rotate synchronously. The operator manually pushes the particleboard until the left and right cutting discs synchronously trim the edges of the particleboard.

The application relates to a roadbed reinforcing structure for municipal roads, which comprises a geogrid for laying on the surface of the roadbed, the geogrid is provided with a gap slot arranged in sequence and at intervals; and a blocking seat arranged on one side of the geogrid, the side of the blocking seat away from the geogrid is provided with a lifting plate arranged in the lifting direction of the lifting plate, the blocking seat is screw-connected with an adjusting rod arranged along the lifting direction of the lifting plate, and the adjusting rod is used for driving the lifting plate to lift; the blocking seat is provided with a slot for the geogrid to pass through, the lifting plate is provided with a plurality of plug-in columns arranged in sequence and at intervals, and the plug-in columns are used for respectively penetrating into the corresponding gap slots. The application has the effects of reducing the additional workload during the laying of the geogrid, improving the laying efficiency of the geogrid, and ensuring the stability of the geogrid.
