Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

As shown in fig. 1 to 4, a geotechnical molding device comprises a base 1, a sliding groove 1.1 is formed in the base 1, fixing structures 2 matched with the sliding groove 1.1 to slide are arranged in the sliding groove 1.1, a mold 3 is fixed between the two fixing structures 2, the mold 3 is matched with a ram 4, the mold 3 and the ram 4 are in different sizes, screw holes are formed in the top of the ram 4, the ram 4 is in threaded fit connection with the bottom of a connecting rod piece 5 through the screw holes, the fixing structures 2 can fix and loosen the molds 3 in different sizes, and the rams 4 in different sizes can also be connected with the connecting rod piece 5 through the screw holes.

Be equipped with the sawtooth on connecting member 5 one side, sawtooth and gear 6 intermeshing, gear 6 links to each other with motor 7 output, and motor 7 is fixed in protecting sheathing 8, and gear 6 also locates in protecting sheathing 8 with connecting member 5, and is equipped with the through-hole that supplies connecting member 5 to pass on protecting sheathing 8, and protecting sheathing 8 is fixed on base 1.

Preferably, fixed knot constructs 2 and includes that two joints are connected with first screw rod 2.2 in the gliding slider 2.1 of mutually supporting with spout 1.1 in spout 1.1, overlap on first screw rod 2.2 and be equipped with stationary blade 2.3 and first nut 2.4. Two first screw rods 2.2 that slide cooperate and tightly lean on mould 3, press from both sides mould 3 tightly, hug closely mould 3 with stationary blade 2.3 through rotating stationary blade 2.3, cooperate first nut 2.4 again to screw up fixedly, play the fixed action to mould 3.

Preferably, a plurality of sliding grooves 1.1 are further formed in the base 1, two sliding blocks 2.1 are also arranged in the sliding grooves 1.1, second screw rods 2.5 are arranged on the sliding blocks 2.1, and second nuts 2.6 matched with the second screw rods 2.5 are arranged on the second screw rods 2.5.
