Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model is as shown in Figure 1 anti-collapse to resistance to wear and drags for sand drilling tool and enclose form by boring wall 1, base plate 8 and top board 9, and a circular top plate 9 is fixed on bores wall 1 upper surface, and described brill wall 1 be column type, and base plate 8 is hinged with brill wall 1 by bindiny mechanism 5.
Described top board 9 upper surface center is provided with square toes Connection Block 11, the upper surface of square toes Connection Block 11 arranges a supporting mechanism, this supporting mechanism side has the flange extended towards horizontal direction, and flange has a circular hole, described top board 9 has extravasating hole 10, and reinforcing rib 2 is symmetricly set between square toes Connection Block 11 and top board 9.
Shown in Fig. 3, described drilling tool also comprises backplane switch device connecting rod 3 and backplane switch device 4, and backplane switch device 4 is arranged on the bottom of boring wall 1 inwall; Described backplane switch device connecting rod 3 top, through the circular hole on braced structures flange, runs through top board 9 downwards, and extend along the inwall boring wall 1 towards base plate 8 direction, its lower end is connected with backplane switch device 4; Backplane switch device connecting rod 3 can move axially along brill wall 1 inwall, when drilling tool needs to unload clearly inner mud, by pressing backplane switch device connecting rod 3, realize the function that base plate is opened, then base plate is under the spring action on backplane switch device connecting rod 3 top, realizes automatically closing.
