Description

A kind of small-sized mixing pile machine

Technical field

The utility model relates to a kind of small pile machine, particularly a kind of small-sized mixing pile machine.

Background technology

Cement mixing pile is to utilize the host of cement as curing compound; Mixing Machine is forced weak soil and curing compound to stir in the ground depths on the spot; Utilize the series reaction that is produced between curing compound and the weak soil, weak soil is hardened become to have the high-quality ground of globality, water stability and certain intensity.Cement mixing pile has been widely used in the foundation treatment engineering of building as a kind of method commonly used in the foundation treatment technology.Cement mixing pile body in the market is long-pending generally bigger, and the required scope of operation is bigger, just is difficult to use for the narrow condition of some working face.The magnitude relationship of body is to the size of the power source power that carries in addition, how under less size, realizes cutting soil and the ability that stirs the soil body preferably, and also being needs the problem that solves.

The utility model content

For solving the deficiency of prior art, the utility model provides a kind of small-sized mixing pile machine.

The utility model technical scheme that adopts of dealing with problems is:

A kind of small-sized mixing pile machine comprises support, and said support upper surface is installed with the frame that control cabinet and lifting motor and vertical fixing are installed; Said lifting motor output is connected with chain along the setting of bracket height direction; Said chain is fixedly connected with motor, and said motor is slidingly mounted on the guide rail of frame, and said motor is connected with control cabinet respectively with lifting motor; Said motor output end fixedly mounts with an end of the drilling rod that is provided with cavity; The said drilling rod other end is fixedly connected with the drill bit that is provided with cavity, and said cavity is connected with the cavity of drilling rod, and the main shaft surface of said drill bit is provided with at least 1 spray orifice that penetrates into cavity; The main shaft of said drill bit is provided with the steel ring that the center is aimed at main-shaft axis; Evenly be welded with at least 3 length of a film wings on the said steel ring, the said long wing other end is fixedly welded on the main shaft of steel ring below, is welded with the front wing that equates with long wing quantity on the external surface of said main shaft lower end; Said front wing is distributed on the angular bisector between the adjacent long wing, is respectively arranged with sawtooth on the outline of the said long wing and front wing.

Further, also be welded with on the said steel ring external surface and equate with long wing quantity and be distributed in the short limb on the angular bisector between the adjacent long wing that said short limb outline is provided with sawtooth.

Further, said drilling rod adopts with drill bit and is threaded.

The beneficial effect of the utility model: the utility model is arranged on each building block on the support, and structure is compact, can be implemented in work in the less space through adopting the suitably frame of height; Drill bit adopts the multi-disc length wing to mix alternate design and at outline sawtooth is set, and improves the ability of machine cutting soil, reaches the purpose of abundant stirring weak soil.

Description of drawings

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

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the vertical view of the utility model drill bit;

Fig. 3 is the sectional view of Fig. 2 A-A direction.

The specific embodiment

With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of small-sized mixing pile machine comprises support 1; Said support 1 upper surface is installed with the frame 5 of control cabinet 2 and lifting motor 3 and vertical fixing installation; Said lifting motor 3 outputs are connected with chain 4 along frame 5 short transverse settings, and said chain 4 is fixedly connected with motor 6, and said motor 6 is slidingly mounted on the guide rail of frame 5; Motor 6 is connected with control cabinet 2 respectively with lifting motor 3; Said motor 6 outputs fixedly mount with an end of the drilling rod 7 that is provided with cavity, and drilling rod 7 other ends are fixedly connected with the drill bit that is provided with cavity 98, and said cavity 9 is connected with the cavity of drilling rod 7; The main shaft surface of said drill bit 8 is provided with at least 1 spray orifice 10 that penetrates into cavity 9; The main shaft of said drill bit 8 is provided with the steel ring of aiming at main-shaft axis at the center 13, in the present embodiment, evenly is welded with the 3 length of a film wings 11 on the steel ring 13; The said long wing 11 other ends are fixedly welded on the main shaft of steel ring 13 belows; Be welded with the front wing 12 that equates with the long wing 11 quantity on the external surface of said main shaft lower end, said front wing 12 is distributed on the angular bisector between the adjacent long wing 11, is respectively arranged with sawtooth on the outline of the said long wing 11 and front wing 12.

Also be welded with on steel ring 13 external surfaces and equate with the long wing 11 quantity and be distributed in the short limb 14 on the angular bisector between the adjacent long wing 11 that short limb 14 outlines are provided with sawtooth.Drilling rod 7 adopts with drill bit 8 and is threaded in addition.
