On the soil that the soil of the dead-soft earth of large quantity of moisture (as contain) constitutes, carry out soil melioration work, curing agent is preferably powder, owing to be stirred blade 7a, 7b, the soil that 7c digs out needs bigger shearing than the soil in the upright opening, the soil that is dug out by traditional stirring structure is bonded on the stirring rod and forms a spherical native ball, stirs and the work of mixed soil becomes and hardly may.

In the present invention, because stirring

vane

7a, 7b, 7c have avoided producing stirring and the hybrid working that spherical native ball also can very be finished soil effectively fully each other with opposite direction rotation.

Describe the dusty material injection device B that dusty material is infeeded rotating shaft 4 now, as shown in Figure 2, it is positioned at the top of rotating shaft 4, and its installation as shown in Figures 2 and 3.

Numeral 35 shows that is used to measure a powder measurements device that infeeds rotating shaft 4.Below measurement mechanism, a hopper 14 is installed in the upper end of outer shaft 9, and the inside of hopper 14 communicates with the inside of outer shaft 9.

In being installed in, the screw rod 15 that is made of an elongated helical blade is on the axle 10 on the external peripheral surface at place, hopper 14 belows.The lower end of screw rod 15 is surrounded by feed cylinder in the taper 16, and this upper end is fixedly attached on the inwall of outer shaft 9.

The lower end of interior feed cylinder 16 is obliquely cut, and locates to pile up above interior feed cylinder 16 open end top edges to prevent dusty material, and dusty material is fallen and is deposited on the dusty material injection valve 36, and this valve is positioned at the below of feed cylinder 16.

Dusty material injection valve 36 has a valve plate 36a, and it is positioned at cylindrical sleeves 37.One group of valve opening 36b and 36c process respectively on valve plate 36a and cylindrical sleeves 37.

In addition, below valve plate 36a, there is a cylindric valve casing 36d to be fixedly mounted on the outer wall of interior axle 10.Valve opening 36e and 36f process respectively on the upper wall and perisporium of cylindric valve casing 36d, thus when switch clockwise or counterclockwise rotate in spools 10 and during outer shaft 9, might open and close above-mentioned valve opening 36b, 36c, 36c and 36f.

Adopt above-mentioned handover operation, can select dusty material device for filling B or dusty material is entered near the little stirring vane 7c, or stop to discharge dusty material.

Below dusty material injection valve 36, end injection valve 27 and the side injection valve 32 of a soil conditioner feeding mechanism C arranged.

Side valve 32 is a cylinder-like structure, and the diameter of its substrate is identical with the diameter of tubular outer shaft 9, and the last open end of side valve 32 engages with the lower end of outer shaft 9 slidably, and its lower end then engages with the outer wall of interior axle 10 loosely.

On the sidewall of side valve 32, be processed with a side valve hole 32b, this Kong Youyi arc valve 32a closes or opens, and this valve is slidably mounted on the inner circumferential surface of sidewall of side valve 32, and can move along this surperficial circumferencial direction.The interior end of arc valve 32a is fixedly mounted on the external peripheral surface of interior axle 10.

In Fig. 4 and Fig. 5, digital 32c represents block, and they are used for controlling the slewing area of valve 32a with respect to side valve 32, and this rotation is caused by the earth resistance that acts on the side valve 32.That is, block 32c matches with the rotation of valve 32a and can make side valve hole 32b or be shown in an open position or in the closed position.At open position, the earth that excavates is injected through side valve hole 32b then in the annulus of soil hardening agent by limiting between tubular outer shaft 9 and the tubular interior axle 10.

End injection valve 27 with a cylindrical wall and a circular bottom plate is rotatably installed in the interior axle 10, and its height and position is identical with the lower end of outer shaft 9.Below injection valve 27, in disk 12 is fixedly mounted on the inner periphery of axle 10 to support end injection valve 27.

As shown in Figure 4 and Figure 5, one group of flaabellum shape fixed valve hole 27a and one group of rotatable valve opening 27b processing are on the base plate of disk 12 and end injection valve 27.

The engagement of a pillar on the lug boss 27c that stretches out from the cylindrical sidewall of end injection valve 27 and the inner panel that is installed in side valve 32 makes end injection valve 27 and side valve 32 can be used as an integral body and rotates together.

When valve opening 27a and 27b alignd, the soil hardening agent of axle 10 can enter the inside of upright opening H through rising pouring hand-hole 27e in injecting, and the rising pouring hand-hole is positioned near the drill bit 6 of 10 lower end.

In addition, inject valve opening 27e on the sidewall of end injection valve 27 and interior axle 10, respectively being processed with, adopt roughly as the aforementioned the same manner of side valve 32 to close and open interior hand-hole 27e.

In Fig. 2, numeral 40 expressions are used to inject the hand-hole of paste curing agent (as floating shape cement), and hand-hole 40 communicates with pulverulent material injection valve 36 and end injection valve 27, thereby the paste curing agent is injected the earth that stirs.

So, because the resistance of earth and soil hardening agent, when interior axle 10 during along a direction rotation, side valve 32 is opened near the earth that is stirred that curing agent can be entered the little stirring vane 7c lower end thereby end injection valve 27 is closed, and when axle 10 when rotating in opposite direction, end injection valve 27 is opened curing agent is entered near the drill bit 6 the earth that is stirred thereby side valve 32 is closed.

Just as explained above, by switching the rotation direction of tubular interior axle 10, can open the supply of beginning or stopping dusty material, and the injection phase of soil hardening agent can be changed into or upper position or lower position.

So, in order to improve the earth of dead-soft, at first dusty material such as the sand with good fluidity injects the soil that excavates, then, when the soil hardening agent injection phase being changed into or when upper position or lower position, soil hardening agent such as cement can inject the earth that excavates.

In this mode, the earth that is excavated, dusty material and curing agent can effectively be stirred and be mixed fully equably, thereby make the soil after the improvement that enough intensity be arranged.The efficient and the reliability of soil melioration work have been improved so widely.
