[0033] Guide rods 13 are fixedly installed at the four corners of the bottom of the bottom template 2, and the guide rods 13 are telescopically connected to the telescopic sleeve 14, and the telescopic sleeve 14 is fixedly installed at the bottom of the prefabricated box body 1.

[0034] The top of both front and rear sides of the prefabricated box body 1 is penetrated with a guide groove 15, and the middle end of the bottom of the guide groove 15 is provided with a limited sliding groove 16. The inner side of the guide groove 15 is slidably connected with a sliding plate 17, and the inside of both sides of the sliding plate 17 is slidably connected with a limited rod 18, and the middle part of the sliding plate 17 is connected with an adjusting screw 19 through a threaded fit, and the limiting rod 18 and the bottom of the adjusting screw 19 are connected with a screed plate 20, and a sliding hole is provided inside the sliding plate 17 corresponding to the limiting rod 18, and the limiting rod 18 slides in the sliding hole, and the limiting rod 18 is fixedly connected to the screed plate 20, and the bottom of the adjusting screw 19 is connected to the screed plate 20 through a limited rotation seat.

[0036] Working principle and use process of the utility model: In the actual application process of the concrete prefabricated panel manufacturing equipment, the bottom template 2 is first placed in the initial position, so that the bottom template 2 is placed on the support frame 3 at the edge of the prefabricated box body 1, and the bottom template 2 is in close contact with the sealing gasket 4, so as to ensure the stability of the installation position of the bottom template 2, so that the bottom template 2 and the prefabricated box body 1 are more tightly connected after the fitting connection, and the concrete slurry is prevented from overflowing during the subsequent prefabricated panel manufacturing;

[0037] When making a prefabricated panel, the concrete slurry in the mixing equipment is poured into the prefabricated box 1 according to the size of the prefabricated panel, and the concrete is vibrated by an external vibrating rod to ensure that the concrete is more compact. Then, the surface of the concrete needs to be leveled. In the specific processing process, the position of the leveling plate 20 needs to be adjusted according to the thickness of the concrete prefabricated panel. When adjusting, the distance between the leveling plate 20 and the sliding plate 17 is mainly adjusted by the limit rod 18 and the adjusting screw 19 to adjust the position height of the leveling plate 20, so as to flexibly adjust the position of the leveling plate 20 according to the thickness production requirements of different prefabricated panels.
