Description

[Detailed description of the invention] (Field of industrial application) This plan is suitable for use when stirring and mixing straw, hay, bran, corn, beet lees, etc. to make feed. This invention relates to a stirring and mixing device for fertilizers, etc.

(Prior art) In conventional devices for stirring and mixing feed, fertilizer, etc., the stirring mixing tank is horizontal or gently inclined, and the gap between the periphery of the spiral blade and the inner bottom surface of the stirring mixing tank is uniform. There are those that are equipped with one screw conveyor or two parallel screw conveyors with spiral blades whose edges are straight in the radial direction, and those that are stirred by the rotation of stirring blades or drums.

(Problem to be solved by the invention) Straw with a length of about 5 cm,
Entanglement, entrapment, or clumping of hay etc. may cause a clogging phenomenon and render the machine inoperable.
Further, after the stirred mixture was discharged downward, it was transported upward by an elevator conveyor or the like and charged into a transport vehicle, which caused problems such as increased equipment size and inconvenience in handling.

(Means for solving the problem) This invention prevents straw, hay, etc. from becoming entangled, entangled, etc.
In addition to preventing clogging due to solidification, the angle of inclination of the stirring mixing tank is set at a relatively steep angle of 25 degrees to 35 degrees, and the circulation flow is repeated, starting from an upward flow at the bottom and then reversing to a downward flow at the top. The upward flow at the top during stirring and mixing is assisted by gravity, and after sufficient stirring and mixing, it is possible to discharge smoothly, and the spiral shape has a curved edge. A rotating body is provided in which a blade-shaped part, a stirring rod part, and a return blade part are sequentially formed from one end of the rotating shaft toward the other end, and the rotating body is formed in the longitudinal direction of the inner bottom of the inclined trough-like stirring tank. The rotating body is arranged along the axial direction of the rotating shaft, and the gap between the lower half peripheral edge of the spiral blade portion and the inner bottom surface is gradually expanded in the rotational direction of the rotating body. Furthermore, there is provided an agitation/combination device for feed, fertilizer, etc., which has a discharge port that can be opened and closed at the inner bottom near the return blade.

(Function) The curved edge of the spiral blade prevents entanglement and entrapment during the transition from downward flow at the top to upward flow at the bottom, and the rotation of the spiral blade prevents contact with the inner bottom surface. The stirring/mixing section that has entered the space between the parts gradually increases the gap to prevent clogging, and the return blades make it easy to reverse the upward flow in the lower part to the downward flow in the upper part, and the stirring rod part Further, it promotes stirring and mixing and facilitates discharge of the stirred mixture from the discharge port.

(Example) Embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the stirring and mixing device 1 for feed, fertilizer, etc. is arranged with the axial direction of the rotating shaft 4 of the rotating body 3 along the length direction of the inner bottom 2a of the inclined gutter-like stirring tank 2. The inclined gutter-like stirring tank 2 has a relatively steep slope with an inclination angle of 25 degrees to 35 degrees.

The rotating body 3 includes a spiral blade portion 5 and a stirring rod portion 6 sequentially from one end 4a of the rotating shaft 4 toward the other end 4b.
and a return blade part 7, and both ends of the rotating shaft 4 pass through the end walls 2b, 2c of the inclined trough-like stirring tank 2 and are supported by bearings 8, 9.

As shown in FIG. 2, the inner bottom portion 2a and the spiral blade portion 5 of the rotating body 3 extend from the connecting portion 2e between the side wall 2d of the inclined gutter-like stirring tank 2 and the inner bottom portion 2a to the other side wall 2f.
A gap 10 between the circumferential edge 5a of the spiral blade portion 5 and the connecting portion 2g between the inner bottom portion 2a and the inner bottom portion 2a is formed so as to gradually become larger as the rotating body 3 advances in the rotational direction A.

Further, as shown in FIG. 2, the end edge of the spiral blade portion 5, that is, the end 4a side of the rotating shaft 4 is a curved portion 5b, and in this case, the curved portion 5b has a crescent-shaped convexity. It has a rim shape, and a curved portion 5b is located at the lower end of the inclined gutter-like stirring tank 2.

Further, the stirring rod part 6 has a base fixed to the rotating shaft 3 in a radially projecting shape and spaced apart in the axial direction, and the return blade part 7 is fixed in the conveying direction of the spiral blade part 5, that is, in the direction of the arrow RO. The blades are twisted to push the conveyed object back in the opposite direction.

A discharge port 11 that can be opened and closed is formed in the inner bottom portion 2a near the return blade portion 7, and this discharge port 11
As shown in FIG. 3, the opening/closing mechanism includes a shutter guide portion 12 fixed to the outer bottom of the inclined gutter-shaped stirring tank 2;
Guide grooves 12a, 12a of this shutter guide portion 12
The shutter 13 is slidably attached to the shutter guide 12 on both sides, and the support pieces 14 and 1 have their upper ends fixed to the shutter guide 12.
4, a rack member 16 fixed to the outer surface of the shutter 13, and a pinion 17 engaged with the rack member 16 and fixed to the handle 15.
The shutter 13 is moved forward or backward through a pinion 17 and a rack member 16, and the discharge port 11 can be opened and closed by the shutter 13.

In the figure, 18 is a drive mechanism, 19 is a column, and 20 is a base.

Since the present invention is constructed as described above, the drive mechanism 18 is operated to rotate the rotating body 3, and straw, hay, bran, etc.
Corn, beet dregs, etc. are successively introduced, and these straw, hay, etc. are stirred and mixed and conveyed along the lower part of the inclined trough-like stirring tank 2 by the spiral blade part 5 as an upward flow at the lower part, and then by the stirring rod. The stirred mixture is further stirred and mixed by the stirring section 6, and the stirred mixture that is successively pushed is eventually pushed back by the return blade section 7, forming a bulge at the upper end of the inclined gutter-like stirring tank 2, and forming a bulge on both sides. With the help of the spreading gravity, the flow becomes downward at the top as shown by arrow C, reaches the lower end of the slope, and due to the rotation of the spiral blade part 5, the flow becomes upward again at the bottom as shown by arrow D. Repeat stirring and mixing while circulating through the channels indicated by arrows B, C, and D.

In particular, the curved portion 5b at the edge of the spiral blade portion 5 prevents straw, hay, etc. from becoming entangled and entrained, and allows the stirred mixture to flow smoothly in the direction of the arrow 2, and gradually as the rotation direction A progresses. The large gap 10 prevents agglomeration and allows sufficient stirring and mixing to be achieved without causing a clogging phenomenon.

After completing sufficient stirring and mixing in this way, the handle 1 is rotated while the rotating body 3 is rotating.
Turn 5 to operate the shutter 13 and open the discharge port 11.
is opened, the stirred mixture is discharged from the inclined upper end side of the inclined gutter-like stirring tank 2, and the stirred mixture can be immediately loaded into a waiting transport vehicle or the like.

(Effects of the invention) This invention uses straw, hay, etc. that are shredded into pieces of about 5 cm by the curved part of the spiral blade part and the gap that gradually becomes larger between the periphery of the spiral blade part and the inner bottom surface. Entanglement when stirring and mixing roughage and concentrate feed,
It is possible to prevent clogging caused by entrainment and agglomeration, and the stirred mixture can be sufficiently circulated and then discharged and immediately loaded into a transport vehicle, etc., which, together with the assistance of gravity, has an energy-saving effect. and the device can be made smaller.
