The many employings of long-spiral drilling machine ground connection bracing or strutting arrangement of the prior art structure shown in Figure 1; Comprise ball seat, have the connection gland 1 and the bolt 2 of ball-and-socket; On comprising the supporter 3 that has ball-and-socket and be connected in supporter 3, said ball seat is used for the dish 4 that contacts with ground; Said connection gland 1 is provided with the hole that supplies bolt to pass; On the supporter 3 with connect gland 1 on corresponding position, hole be provided with the blind hole that is used for bolt 2 secure fit, said blind hole is a silk hole, said connection gland 1 is fixed together through turnbuckle 2 with ball seat.But in actual use, because the ground out-of-flatness, the situation that turnbuckle is fractureed often appears, still since bolt in lean on thread segment down to fracture in the blind hole of ball seat, take out very difficulty, give on-the-spot installation and keep in repair and bring a lot of inconvenience.

Summary of the invention

The purpose of the utility model is to provide a kind of long-spiral drilling machine ground connection bracing or strutting arrangement, to solve the problem that is difficult for changing the bolt that fractures in the prior art.

In order to address the above problem; A kind of long-spiral drilling machine ground connection of the utility model bracing or strutting arrangement; Comprise ball seat, have the connection gland and the bolt of ball-and-socket; Said ball seat comprises the supporter that has ball-and-socket, and said bolt is a turnbuckle, supplies said turnbuckle to pass the back bolt penetration hole fastening with corresponding nut at said supporter with connecting to be equipped with on the gland; Said supporter bottom is provided with seal face down, and correspondence position is provided with the opening that supplies turnbuckle to pass on this seal face and turnbuckle or nut compression fit and this seal face.

Said ball seat also comprises and is used for the deep bid that contacts with ground; Set firmly a shallow bid in the bottom of said supporter; The soffit of this shallow bid is described seal face; The column that between said shallow bid and said deep bid, is connected, said shallow bid are provided with and supply said turnbuckle to pass back and the fastening bolt penetration hole of corresponding said nut.

On said connection gland, be provided with boss, on the correspondence position of ball seat, be provided with groove with said boss complementary fit.

Said boss is an annular boss, and described groove is a cannelure.

In the ball-and-socket of said supporter, be provided with the oil storage tank that is used to place lubrication oil.

Said oil storage tank be arranged in the bottom of said supporter ball-and-socket and along the ball-and-socket radial direction to extending below.

The utility model changes the blind hole of supporter on the ball seat in the prior art into bolt penetration hole; Connect pressing plate and supporter through being located in being connected of turnbuckle and corresponding nut in connection pressing plate and the supporter; When turnbuckle ruptures; The replacement of only need releasing gets final product, and is very convenient, solved the problem of turnbuckle replacing difficulty in the prior art.
