Claims

[Scope of utility model registration request]

A water stop plate 2 for soil adjustment is fixed to the front part of the tip auger shaft 1, and a target 3 is fixed to the front part of the inside of the tip auger shaft 1 with a hollow space, so that the center can be measured from the rear with a transit 27, A tip blade 4 for direction correction with the cutting edge 31 of a steel pipe facing downward is fixed to a bowl-shaped tip blade mounting pedestal with a tip blade mounting bolt 12 to form one unit, and a hump tube is installed in the rear groove. The adapter 6 is interlocked so that it can rotate freely, and the lead pipe rubber ring 8 is inserted between the hume pipe 10 and the lead pipe 9 as a support tool for the lead pipe 9, and the lead pipe 9 and the tip blade mounting base 5 are connected to the lead pipe joint. The auger shaft 11, whose center is hollow, and the auger blade 7 are connected by bolts 30, and an excavation blade is attached to the front of the auger shaft 1 at the tip so that the excavated earth and sand can move backward. Propulsion machine body 26
An excavating auger device connected to an auger drive unit 16 that moves back and forth by a hydraulic cylinder 25 and rotates left and right by a prime mover 15 is inserted as one unit, and the lead pipe 9 inside the humid pipe 10 is inserted. The lead pipe joint clutch 19 is connected and supported by the front part of the lead pipe bearing ring 22 and the propulsion plate 18. By supporting the hume tube 10 with the hume tube adapter 24 and moving the auger drive section 16 forward, the lead tube clutch teeth 17 fixed to the outside of the auger drive section 16 are attached to the rear of the lead tube joint clutch 19. If the lead tube rotation stopper 23 of the lead tube receiving ring 22 and the lead tube rotation tooth 20 were engaged with each other by moving forward while still engaged with a certain lead tube rotation boss 21 and moving the propulsion unit body 26 backward. When the object comes off, the auger drive unit 16 and lead pipe joint clutch 19 freely rotate as one unit to correct the direction during excavation. If the structure is such that it can be confirmed by the installation position of the Into bolt 30', the vertical and horizontal direction corrections can be made using the water stop plate 2 for soil adjustment.
By moving the blade forward, a dirt intake port is created on the lower side of the slope of the direction correction tip blade 4, and it is possible to take in the earth and sand from there. 31 is facing downward, earth pressure is applied to the upper part of the outer side of the tip blade 4 for direction correction, and the blade moves in the opposite direction to the direction of movement of the blade 31, and more earth than necessary flows in due to the pressure of groundwater, etc. In this case, the structure is such that the front part of the tip blade mounting pedestal 5 is sealed when the earth and sand adjustment waterstop 2 is retreated, so this adjustment makes it possible to achieve consolidation or reduction propulsion. Propulsion device for caliber pipe consolidation cutting.
