Abstract

The invention relates to a device for mixing soil materials, especially for mixing a blend component directly into the soil materials in the ground. The device comprises at least two mixing drums (2) rotatable about their axes of rotation, which are at a short distance from one another. Between the drums (2) a fixing frame (14) to which is fixed a plunging arm (1). At the upper end of plunging arm (1) are attachment means (10) for attaching to a power machine extension arm. The axes of rotation of the mixing drums (2) are inclined in comparison to the plane perpendicular to the vertical axis of the device in such a way that when the plunging arm (1) is in the vertical direction, the axes of rotation of the mixing drums (2) slant downwards towards the outer ends of the drums. In this case the ends of the mixing drums closest to one another are essentially closer to one another at their lower edges than at their upper edges. Due to this, the body of the device does not form a dead zone which would resist the working motion.

From open source literature US4133397A1 and the known a kind of equipment that is used for mixing soil materials of JP2007262819, wherein, main body branch also is fixed to bulging those ends away from each other.Extend to outside the drum or extend to the outer peripheral main body in Mixed Zone at least and hindered operation and mixed process.

Summary of the invention

Purpose of the present invention promptly is to solve this problem by improving this equipment, makes framework can upwards not form the dead band the operator again, also can not hinder in treating stable material or the action of the operation earthward.

This purpose realizes by the present invention based on disclosed feature in the claim 1.

Preferred implementation of the present invention openly in the dependent claims.

Description of drawings

Hereinafter with reference to description of drawings one embodiment of the present invention, wherein:

Fig. 1 shown along the intercepting of the A-A line of Fig. 2 according to equipment of the present invention;

Fig. 2 shown see from the side according to equipment of the present invention;

Fig. 3 has shown the stereogram that identical device is seen sideling from the top; With

Fig. 4 has shown from the identical device of seeing previously.

The specific embodiment

Equipment according to this embodiment comprises two mixing drums 2 that can rotate around their rotation, and these two mixing drums are each other at a distance of very short distance.The fixed frame 14 that is made of the bigger short tube of diameter is between the drum 2.The lower end of inserting arm 1 is fixed on the fixed frame, and the upper end of insertion arm 1 is the link 10 that is used to be connected to the power tool adjutage.

The rotation that novel aspect of the present invention is mixing drum 2 is compared with the plane perpendicular to the vertical axis of this equipment, and the mode of inclination is that the rotation of mixing drum 2 tilts towards the outer end of drum downwards when inserting arm 1 and be in vertical direction.In this case, the mutual hithermost end of mixing drum 2 is in fact close more mutually than their top edge at their lower limb.Distance between the lower limb of the described end of drum 2 is preferably less than the minimum thickness that inserts arm.

Mixing drum 2 be shaped as truncated cone shape, and the cone angle that preferably rouses of the rotation angle of inclination with respect to the horizontal plane of drum is only about half of.In this case, the bottom of drum 2 is levels, is favourable under the situation of this mixed material in Flat bottom container.On the external surface of drum 2 hybrid blade with desirable shape or the fin 11 of desired number.Preferably inserting blade or the level of fin 11 or the fixedly prodger 12 below them that extends to mixing drum when arm 1 is in vertical direction between the lower limb of mixing drum 2.In this case, blade or fin 11 will be not in container mixes can contacting container the bottom.

By hydraulic motor 3 being set, mixing drum being installed in preferably carrying out suspending and rotating of mixing drum 2 on the bearing of motor in mixing drum inside.In this case, do not need to utilize chain, cogwheel or axle to carry out independent transmission of power.Also do not need independent motor cover in the framework, motor cover can be driven in the ground and can hinder the motion of equipment for it in operating process.Reference marker 8 has been pointed out hydraulic tube or pipeline, and it leads to each motor 3 that inserts arm 1 inside respectively.

In a kind of preferred implementation of the present invention, the required volume flow of the hydraulic motor of two or more drums 23 is by being connected to the little of same axle but hydraulic pump at a high speed distributes substantially equally.Therefore, each mixing drum 2 can not rotate slowly than other drums substantially, even it has higher load.Pump can be in actuator (being power machine) or in mixing apparatus according to the present invention.With the pump mechanical connection so that its can also carry out by other means with the rotation of essentially identical speed, rather than by pump being connected on the same axle.

According to another kind of preferred implementation of the present invention, the distribution of volume flow does not utilize assignment of traffic pump or flow divider valve to realize, but the drum motor is a variable displacement motor, regulate rotation amount by change, keep the rotary speed of variable displacement motor basic identical along with the volume flow of introducing.

Also may use variable displacement motor and assignment of traffic.Drum will rotate with identical speed, but regulate the rotation volume (rotational volume) of all drums, make to obtain bigger torque.In this case, rotary speed will significantly reduce, because the power of configuration is fixed.When having high shear strength, soil needs high torque (HT).

In a kind of preferred implementation of the present invention, the transitional region between the main body of hydraulic motor 3 and the rotary shaft 5 is utilized removable washer sealing, and the open belt 7 of removable packing ring utilization is held in place.Mixing drum 2 utilizes flange joint to be fixed to the flange of the rotary shaft 5 of hydraulic motor 3.Hydraulic motor 3 utilizes flange joint to be fixed to the mounting flange 4 of main body 14 again.

On the outside of inserting arm 1, the top of each mixing drum 2 is stabilizing agent carrier pipes 9 of fixing, and its direct opening is above mixing drum 2.

Clearly, the present invention is not limited to top embodiment.Plural mixing drum 2 can be arranged.For example, in the structure with three drums, from mixing drum 2 tops, their rotation is relative to each other 120 ° angle.A kind of structural selection can also be the bulging structure with two continuous initial introductions.This selection can be implemented when the needs high power capacity.Simple structure according to equipment of the present invention makes its very light in weight, and this means only need be from enough hydraulic powers of excavator.
