The invention discloses a sand suction and mud suction circulation launching device, and relates to the technical field of sand suction and mud suction devices. The sand suction and mud suction circulation launching device comprises a
chassis, a suction mechanism, an auxiliary mechanism, a
water jet scalpel mechanism and mud
discharge mechanisms, wherein telescopic rods are fixed to the edge of the upper surface of the
chassis at equal intervals, the suction mechanism is arranged in the center between the
chassis and a supporting disc, the auxiliary mechanism is installed on the edge of the upper portion of the supporting disc and composed of a unit ladder block, a through
pipe, a through net, a ring
pipe and an injection
pipe, the
water jet scalpel mechanism is arranged in the center of the upper portion of the supporting disc, and the mud
discharge mechanisms penetrate through positioning sleeves. According to the sand suction and mud suction circulation launching device, the
water jet scalpel mechanism is assisted through the auxiliary mechanism, so that mud and sand can be quickly scattered after passing through a mud passing net, on one hand, the operation pressure of the water jet scalpel mechanism is reduced, and on the other hand, a large amount of mud and sand cannot be left at dead corners around the water jet scalpel mechanism, complete output of the mud and sand canbe guaranteed, and the mud and sand conveying efficiency is improved.
