Description

Multitool dish rectangular top pipe machine

Technical field

The utility model relates to the push-bench that a kind of jacking construction is used, the especially a kind of People's Bank of China that trenchless technology lays underground rectangular cross section, push-bench of garage's passage of being used for.

Background technology

At present, the most employing excavation construction of constructing of street passage method is crossed by underground People's Bank of China, and not only occupied ground is big for this, influence basin wide, long construction period, but also will suspend traffic, and brings inconvenience to citizen.And underground People's Bank of China crosses the section of street passage and mostly is rectangle, again can not be with common circular construction by pipeline jacking method.Therefore, under this background condition, we have researched and developed " multitool dish rectangular top pipe machine ", and successfully apply in the practice of multinomial engineering, all obtain the satisfied effect of other people.

Summary of the invention

The utility model is that a kind of multitool dish rectangular top pipe machine will be provided.

For achieving the above object, the technical solution of the utility model is: a kind of multitool dish rectangular top pipe machine, comprise housing, clay bin, be characterized in: housing centre, clay bin front are provided with a big cutterhead, on four angles of housing a little cutterhead is set respectively, and little cutterhead is positioned at big cutterhead back.

Big cutterhead is by big bite, big blade row, and big center cutter, big blade row seat constitutes, wherein, the machete arrange seats is in the centre of big cutterhead, and front end is provided with big injected hole, and fixedly connected big center cutter, be evenly equipped with five big blade rows on the excircle, be installed with big bite above the big blade row.

Little cutterhead is by pocket knife row seat, little center cutter, little blade row, little bite, wherein, the pocket knife arrange seats is in the centre of little cutterhead, and front end is provided with little injected hole, and fixedly connected little center cutter, be evenly equipped with four little blade rows on the excircle, be installed with little bite above the little blade row.

The clay bin front center is provided with bracing piece, and the lower end is provided with into Tu Kou and conveying worm is installed.

Big blade row back is provided with big stirring rod; Pocket knife row back is provided with little stirring rod.

The beneficial effects of the utility model are: in the housing centre, the clay bin front is provided with a big cutterhead, on four angles of housing a little cutterhead is set respectively, and little cutterhead is positioned at big cutterhead back.The area of cut of five cutterheads can reach more than 90% of push-bench rectangular cross section.When big cutterhead and four pocket knife dishes rotate simultaneously the soil body is cut, stirs, the soil in the clay bin is become have good plasticity and mobile the time, it had have certain impermeability.

Description of drawings

Fig. 1 is a structural front view of the present utility model;

Fig. 2 is along the sectional view of A-A among Fig. 1;

Fig. 3 is along the sectional view of B-B among Fig. 1;

Fig. 4 is a work effect schematic diagram of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1 to Figure 3, multitool dish rectangular top pipe machine of the present utility model comprises big bite 1, big blade row 2, big center cutter 3, big injected hole 4, big stirring rod 5, clay bin 6, big blade row seat 7, conveying worm 8, pocket knife row 9, housing 10, bracing piece 11, big cutterhead 12, advances soil mouthfuls 13, pocket knife row seat 14, little injected hole 15, little center cutter 16, little stirring rod 17, pocket knife row 18, little bite 19.

Housing 10 centres, clay bin 6 fronts are provided with a big cutterhead, on four angles of housing 10 a little cutterhead is set respectively, and little cutterhead are positioned at big cutterhead back.

Big cutterhead is by big bite 1, big blade row 2, big center cutter 3, big blade row seat 7 constitutes, and wherein, big blade row seat 7 is positioned at the centre of big cutterhead, front end is provided with big injected hole 4, and fixedly connected big center cutter 3, be evenly equipped with five big blade rows 2 on the excircle, be installed with big bite 1 above the big blade row 2.

Little cutterhead is by pocket knife row seat 14, little center cutter 16, pocket knife row 18, little bite 19, wherein, pocket knife row seat 14 is positioned at the centre of little cutterhead, front end is provided with little injected hole 15, and fixedly connected little center cutter 16, be evenly equipped with four pocket knife rows 18 on the excircle, be installed with little bite 19 above the pocket knife row 18.

Clay bin 6 front center are provided with bracing piece, be equipped with into native mouth 13 about the lower end and conveying worm 8 is installed.

Big blade row 2 back are provided with big stirring rod 5; Pocket knife is arranged 18 back and is provided with little stirring rod 17.

Because the section configuration after cutterhead rotation, the cutting is circular, and the section configuration of push-bench is a rectangle, so a cutterhead can not be accomplished hundred-percent cutting, stirring to the rectangular cross section of push-bench.But for the expansion of trying one's best cutting, the area that stirs, the utility model is provided with a big cutterhead in the centre of push-bench, its cutting diameter can be slightly than the height of push-bench more greatly.On four angles of push-bench, a little cutterhead is set respectively.Big cutterhead stretches out forward, the indentation backward of little cutterhead some, the cutting scope of large and small cutterhead has certain lap.Through arranging that so as shown in Figure 4, the area of cut of five cutterheads can reach more than 90% of push-bench rectangular cross section.

Multitool dish rectangular top pipe machine adopts the earth pressure balance mode to work: when big cutterhead and four pocket knife dishes rotate simultaneously the soil body is cut, stirs, soil in the clay bin become have good plasticity and mobile the time, it had have certain impermeability.If run into the big soil of sand content, then can improve the soil body by a certain proportion of clay slip of the injection of large and small cutterhead injected hole in clay bin, make it also reach impermeability.
