Description

[Detailed description of the invention] (Industrial application field) This invention 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 use in other applications.

(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 of the stirring mixing tank is uniform. There are also systems that are equipped with one screw conveyor or two screw conveyors in parallel with spiral blades whose edges are straight in the radial direction, or systems that stir by the rotation of stirring blades or drums.

(Problem to be solved by the invention) Straw, hay, etc. about 5 cm in length become entangled, trapped, and hardened in the uniform gap between the inner bottom of the stirring mixing tank and the lower periphery of the spiral blade. This can cause clogging and make it impossible to operate, and the equipment is large because the stirred mixture is discharged downward and then transported upwards by an elevator conveyor and charged into a transport vehicle. There were problems such as it was difficult to handle and it was difficult to handle.

(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 made possible by the assistance of gravity, and after sufficient stirring and mixing, the discharge can be smoothly carried out toward the upper part of the slope, and the edge is curved. A rotating body is provided in which a spiral blade portion, a stirring rod portion, and a return blade portion are sequentially formed from one end of the rotating shaft toward the other end, and the mountain of the inclined trough-like stirring tank is The rotating bodies are arranged parallel to each other with the axial direction of the rotating shaft extending in the length direction of the left bottom and right bottom of the shaped bottom, and the lower half periphery of the helical blade of these rotating bodies and the For feed, fertilizer, etc., the gaps between the left bottom surface and the right bottom surface are gradually expanded in the direction of rotation of the rotating body, and a discharge port that can be freely opened and closed is formed in the inner bottom near the return blade. Provide a stirring and mixing device.

(Function) The curved portion of the end edge of the spiral blade portion of each rotating body prevents entanglement and entrapment during the transition from the upper downward flow to the lower upward flow.
In addition, the stirred mixture that enters between the left bottom surface and the right bottom surface due to the rotation of the spiral blade does not cause clogging as the gap gradually increases.
The return blade portion facilitates reversing the upward flow in the lower portion to the downward flow in the upper portion, and the stirring rod portion further promotes stirring and mixing and facilitates discharge of the stirred mixture from the discharge port.

As shown in FIG. 2, the helical blade portion 8 of the rotating body 4 and the left bottom portion 3A of the mountain-shaped inner bottom surface 3 are connected to a line connecting the centers of the rotating shafts 6 and 7, that is, the helical blade portion 8. . The gap 18 between the peripheral edge 8a of the lower half of the spiral blade part 8 and the left bottom part 3A is gradually enlarged in the direction of rotation of the rotating body 4 so as to increase the gap.

The related structure between the helical blade part 13 of the rotary body 5 and the right bottom part 3B of the chevron-shaped bottom surface 3 is similar to that of the rotary body 4, and the lower half of the helical blade part 13 increases in the rotational direction of the rotary body 5. A gap 19 between the peripheral edge 13a and the right bottom portion 3B is gradually enlarged.

Further, as shown in FIG. 2, the edges of the spiral blade portions 8 and 13 are curved portions 8b and 13b that are convex with respect to the rotation direction, and in this case, the curved portions 8b and 13b are It has a crescent-shaped convex edge shape, and curved portions 8b, 13 are provided at the lower end of the inclined gutter-like stirring tank 2.

Since the present invention is configured as described above, the drive mechanism 27 is operated to rotate the rotating bodies 4 and 5, and straw, hay, bran, corn, and beets are placed on the lower end of the inclined gutter-like stirring tank 2. The lees, etc. are successively introduced, and while the straw, hay, etc. are stirred and mixed, the spiral blades 8, 13 are moved along the lower part of the inclined gutter-like stirring tank 2.
The stirred mixture is conveyed as an upward flow at the bottom by the stirrer, and then stirred and mixed by the stirrer rods 9 and 14, and the stirred mixture that is successively pushed is eventually pushed back by the return blades 10 and 15, resulting in inclined trough-like stirring. It forms a bulge at the upper end of the slope of the tank 2, spreads to both sides, becomes a downward flow at the top as shown by arrow D with the help of gravity, reaches the lower end of the slope, and rotates the spiral blades 8, 13. As a result, the flow returns to the bottom upward direction as shown by the arrow E, and in this way, stirring and mixing are repeated while circulating through the channels shown by the arrows C, D, and E.

In particular, the curved portions 8b and 13b of the edges of the spiral blade portions 8 and 13 cause entanglement of straw, hay, etc.
The stirring mixture is prevented from being trapped and flows smoothly in the direction of the arrow E, and the gaps 18 and 19 are gradually enlarged as the rotation direction A and B progress, thereby preventing clumping and clogging. Sufficient stirring and mixing can be achieved.

After sufficient stirring and mixing is completed in this way, the handle 24 is turned while the rotors 4 and 5 are kept rotating, the shutter 22 is operated, the discharge port 20 is opened, and the stirred mixture is transferred to the inclined gutter-shaped stirring tank. It can be discharged from the upper end of the slope of No. 2 and immediately loaded into a waiting transport vehicle or the like.
