In order to achieve the above purpose, the technical scheme of the utility model is that: a seabed pipe body stone falling and fixing mechanism comprises a mechanism body, wherein the mechanism body comprises a rack, movable supporting legs, a sliding frame, pulleys, a blanking bin, a blanking pipe and a high-pressure water gun installed on the blanking pipe, more than one movable supporting legs are respectively arranged at two ends of the rack, the blanking bin is arranged on the sliding frame, the pulleys are installed on the sliding frame through bearings, the pulleys are arranged on the rack in a sliding manner, the blanking pipe is respectively arranged at two sides of the blanking bin, one end of the blanking pipe is hinged with the blanking bin through a hinged shaft, the other end of the blanking pipe is arranged below the rack, and the high-pressure water gun is fixedly connected at one end, away from the blanking bin, of the blanking pipe; a swing adjusting hydraulic cylinder is hinged between the blanking bin and the blanking pipe.

According to the arrangement, when the mechanism body is used for blanking, the broken stones in the blanking bin are discharged through the blanking pipes on the two sides, the high-pressure water gun on the blanking pipes pushes the discharged broken stones to move towards the direction of the pipe body, and the broken stones are laid on the two sides of the pipe body, so that compared with the conventional mode of directly dropping the materials on the pipe body to form material pile locking, the locking is firmer, and the blanking efficiency on the two sides is higher; in addition, the angle of the discharging pipe can be adjusted by swinging the adjusting hydraulic cylinder so as to be suitable for locking pipes of different sizes.

Furthermore, the movable supporting legs comprise telescopic hydraulic cylinders and more than two sections of telescopic legs, adjacent telescopic legs are mutually inserted, the telescopic hydraulic cylinders are arranged between the adjacent telescopic legs, and the uppermost telescopic leg is arranged on the rack. Thus, the length of the movable supporting leg can be adjusted according to the requirement.

Furthermore, the frame is composed of two longitudinal beams which are parallel to each other.

Furthermore, the number of the movable supporting legs is four, and the four movable supporting legs are respectively arranged at the connecting positions between the frame cross beams. Thus, the mechanism body is stably supported.

Further, the blanking pipe is equipped with two, and the symmetry sets up in the below of blanking storehouse.

Furthermore, one end of the blanking pipe, which is far away from the blanking bin, is bent towards the direction close to the other blanking pipe. Above setting up, unloading pipe exhaust rubble relies on inertial effect, is close to the body, with the cooperation of high-pressure squirt for unloading pipe exhaust rubble removes to the both sides of body, like this, improves the utilization ratio of building stones, has both improved efficiency, has also reduced the quantity of building stones, thereby the cost is reduced.

Furthermore, the feed bin include body and guide portion, this internal cavity that has, be located the middle part in this body and be ascending and be triangular guide portion. Thus, the stone is divided into two paths by the material guide part and is discharged from the discharging pipe.
