The invention belongs to the technical field of agricultural water and fertilizer machines, and particularly relates to a movable water and fertilizer all-in-one machine which comprises an agricultural water and fertilizer machine assembly and a moving mechanism, the moving mechanism comprises a base and four driving shafts, the four driving shafts are connected to the front side and the rear side of the base through shafts, and driving wheels are integrally formed at the outer ends of the driving shafts; the agricultural water and fertilizer machine assembly is fixedly installed above the base through bolts, cams and a plurality of ground gripping shafts are arranged in the four driving wheels, a plurality of sliding grooves are evenly formed in the driving wheels, the ground gripping shafts are slidably connected into the sliding grooves, the cams are arranged in the middles of the driving wheels, and the ground gripping shafts are arranged in the sliding grooves. A counter bore is formed in the driving shaft, a shaft rod is slidably connected into the counter bore, a limiting part is arranged at the sliding connection position, and one end of the shaft rod and the cam are integrally formed. The outer end of the ground gripping shaft is sharp, the inner end of the ground gripping shaft is arc-shaped, and the device solves the problems that an existing agricultural water and fertilizer machine is difficult to move and low in efficiency in actual farmland application.

This application relates to the field of hot molding processing technology, specifically a hot molding pre-assembly fixture and a hot molding pre-forming method. The hot molding pre-assembly fixture includes a central mold and side molds; a first anti-slip portion is provided on the first clamping surface of the central mold to increase the frictional force on the material layer in the web region; a second anti-slip portion is provided on the second clamping surface of the side molds to increase the frictional force on the material layer in the flange region; and the groove depth of the first anti-slip portion is greater than the groove depth of the second anti-slip portion. In this embodiment of the hot molding pre-assembly fixture, the first anti-slip portion can apply an effective dragging force to the material layer in the web region, causing the material layer to follow the mold movement and fully extend. The second anti-slip portion allows for a differentiated matching relationship between the frictional resistance of the side mold to the material layer in the flange region and the frictional driving force of the central mold to the material layer in the web region. This depth difference helps to limit unintended slippage of the material layer in the flange region during the molding process.
