Rice husk is reused as an important supplement fertilizer for the silica of rice cultivation, but even if the rice husks are laid on the rice field as they are, they are composed of strong husks containing a lot of silica, so the rot in the soil is very slow. Only progress.
In recent years, rice husks have been re-used as silica supplement fertilizer in the same shape because of the utilization efficiency of rice fields.
In order to proceed with the rot of rice husk, a process that slightly changes the state of the rice husk, such as scratching or folding the surface of the rice husk, is sufficient. The conventional rice husk pulverizer, such as No. 2 rice husk grinder, is a method of pulverizing and pulverizing, and the rice husk is refined more than necessary, and handling of the rice husk that has become fine powder is inconvenient.
In other words, if the grain size of the rice husk pulverized product becomes too fine than necessary, when it is sprayed on the rice field, it is handled for reuse, such as being scattered outside the target location, re-aggregated in a powder state, and becoming a lump. Was cumbersome.
If the rice husk remains as it is, the rot hardly progresses in the soil, but if the rice husk is cracked or broken and processed so that a textured surface different from the original husk epidermis appears, the rot will progress and the powder will fall. It has been known for a long time among agricultural personnel that soil rot progresses without processing into a fine size until it is shaped.
In addition, the rice husk pulverizer of Patent Document 1 and the rice husk pulverizer of Patent Document 2 are systems in which the rotary blade is directly collided with the rice husk to crush, shred, and grind the rice husk. The husks contained in a lot contained the blades, and the blades had to be replaced frequently.
Therefore, the present invention is not a method of directly colliding, crushing, chopping, and pulverizing the rice husk with a cutter blade that rotates at high speed, but generates a wind speed of 80 m / second or more in the casing with a large propeller type blade. A rice husk breaking treatment device that reduces the size of the rice husk by the wind force of the rotating blades and scatters to the cylindrical body of the outer casing and passes through the through hole provided in the casing to break the rice husk at the edge of the through hole. The purpose is to provide.
Another object of the present invention is to provide a rice husk breakage treatment apparatus that does not affect the particle diameter and processing amount of the broken rice husk even if the rotary blade and the through hole are worn.

(1) The rice husk breaking processing apparatus of the present invention includes a rice husk processing unit that scatters the rice husk supplied from the sample supply port radially outward. The rice husk processing unit has a zigzag shape on the cylindrical wall in the casing. A cylindrical screen in which a plurality of through-holes having a hole diameter of 10 to 25 mm are formed, and a trapezoidal plate in which an upper side is arranged inside and a lower side larger than the upper side is arranged outside And a rotating body that is rotatably mounted on a rotating plate that is configured to support the rotation of the rotating plate, and the wind pressure of the rotating plate that rotates at a peripheral speed of 40 to 120 m / sec. The longitudinal direction is aligned along the wind flow so that the rice husks are scattered and scattered on the cylindrical wall of the screen, and the radially outermost peripheral portion of the rotating rotating body is not in contact with the inner wall of the screen. Near So as to face with the chaff that the scattered passed into the through hole wherein the radial outermost portion and the by Oridan action and fluid shear in cooperation with the through hole to Oridan the chaff and small-sized while in the casing and discharged to the discharge path, characterized in that the said ejected chaff from the discharge port to be transmitted to the outside of the casing.

<Embodiment>
DESCRIPTION OF EMBODIMENTS A rice husk breaking processing device according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a rice husk breaker, FIG. 2 is a plan view, FIG. 3 is a left side view, and FIG. 4 is a right side view.

  As shown in FIGS. 1 to 4, a rice husk breaking processing apparatus 10 includes a gantry 11 on which the husk breaking processing device 10 is installed, a sample insertion port 12 on the front surface, a broken product discharge port 13 on the upper side, and a casing 14 constituting a rice husk breaking processing unit. And a drive mechanism 15 such as an electric motor provided on a side surface of the casing 14 and connected via a belt or the like.

FIG. 5 is a schematic view of a screen constituting the rice husk smashing processing unit of the embodiment, where (a) is a left side view, (b) is a front view, and (b) is a right side view.
6A and 6B are schematic views of a rotating body constituting the rice husk breaking processing unit, where FIG. 6A is a left side view, FIG. 6B is a front view, and FIG. 6B is a right side view.
As shown in FIG. 5, the screen 17 is, for example, a stainless steel cylinder having an open bottom and a lid portion. A through hole 16 having a hole diameter of about 10 to 25 mm maintains a gap in the cylindrical wall. Many are formed.
If the hole diameter of the through hole is less than 10 mm, the cutting process proceeds excessively, the size of the processed product becomes too small, and the processing efficiency deteriorates. Moreover, when the rice husk contains moisture, the through hole 16 is easily clogged. If the hole diameter exceeds 25 mm, a large number of rice husks that pass without being treated may be generated.
In FIG. 5, in order to increase the area of the through-hole, the arrangement is staggered, but in the drawing, a part thereof is omitted.

The cylindrical wall of the screen 17 can be formed as a pipe by winding a stainless steel plate or the like and connecting the peripheral ends. A mounting ring 17a is provided around one of the openings of the screen 17 and is fixed to the casing 14 with bolts.
Note that the shape of the through hole 16 may be a square or a triangle other than the round hole.

In addition, a cylindrical screen 17 in which a plurality of through holes 16 are formed around the cylindrical wall is disposed in the casing 14 of the rice husk breaker 10.
Further, in the screen 17, a rotating body 20 is rotatably provided with a plurality of rotating plates 22 attached to the rotating shaft 21 and extending radially in the radial direction.
FIG. 6 shows a case where the number of the trapezoidal plate-like rotating plates 22 is eight, but the shape and number of the rotating plates 22 are not limited, and the amount of rice husk processing and the size of the rice husk breaking processing device are not limited. An appropriate shape and number are arranged depending on the size and the like.
Further, in FIG. 6, the shape of the outermost peripheral portion 23 in the radial direction of the rotating plate 22 is formed linearly in accordance with the shape of the cylindrical wall of the screen 17, but an appropriate distance from the cylindrical wall of the screen 17 is maintained. Is determined as appropriate. In the embodiment, the interval is 4 to 5 mm.

  The rotational speed of the rotator 20 in the screen 17 varies depending on the type of rice husk, the amount of moisture, the amount of processing, etc., but is, for example, a peripheral speed of 40 to 120 m / second, and more preferably 70 to 100 m / second. This is because if the peripheral speed is less than 40 m / sec, the rice husk cannot be sufficiently processed, and if the peripheral speed exceeds 120 m / sec, a special motor or a speed increasing mechanism is required, leading to an increase in cost.

In the rice husk breaking processing device 10, a discharge path 14a is formed on the outer peripheral side (between the casing) of the screen, and a rice husk processing portion 17b is formed on the inner peripheral side of the screen.
As shown in FIG. 7, the rice husk M0 introduced from the sample inlet 12 is subjected to an instantaneous wind pressure action by a large number of rotating plates 22 of the rotating body 20 rotating at high speed in the rice husk processing unit 17b.
It is scattered on the cylindrical wall of the surrounding screen 17. The rice husk passes through the through-hole 16 in the cylindrical wall.
At this time, as shown in FIG. 8, the hole diameter L0 of the through hole 16 is designed to be larger than the long diameter L1 of the rice husk, so that it can pass through.
By the wind pressure action of the rotating body 20 rotating at high speed, the rice husk M0 has its longitudinal direction aligned along the wind flow and scattered, and its tip part (in the case of FIG. 7B) or intermediate part (see FIG. 7 (c)) collides with the edge (edge) of the through-hole 16, breaks in the direction perpendicular to the longitudinal direction of the rice husk M0, and is reduced in size by the fluid shearing action when passing through the through-hole 16 At the same time as M1, the folded cross section S of the chaff M1 is exposed.
Thereby, the size of the rice husk which passed through the through-hole 16 and was discharged | emitted by the casing can be made into a size required for decay when it embed | buries in soil, From the exposed rice husk M1 folding cross section S Moisture is easily absorbed and decay in the soil is promoted.

Further, the radially outermost circumferential portion 23 of the rotating plate 21 of the rotating body 20 has an outermost circumferential raceway surface having an interval of about 4 to 5 mm with respect to the inner wall of the screen 17.
The rice husk M0 scattered by the wind pressure action accumulates in a space of about 4 to 5 mm, and the radial direction of the rotating plate 22 arranged radially from the center of rotation so as to face the inner wall of the screen 17 is faced. The material is broken and discharged from the through hole 16 by the breaking action when colliding with the outer peripheral portion 23 and the edge of the through hole 16 and the fluid shearing action when passing through the through hole.

<Effect of the apparatus according to the embodiment>
In the rice hull breaking processing apparatus according to the embodiment of the present invention, a cylindrical screen 17 having a large number of through holes 16 formed in a cylindrical wall is disposed in a casing 14, and a predetermined circumferentially direction is provided in the screen 17. By the cooperation of the rice husk breaking processing device including the rotating body 20 provided with a plurality of rotating plates 22 radially from the center of rotation at intervals, and the rotating plate 22 and the through-hole 16 of the screen 17, the casing 14. By configuring the inner rice husk M0 to be cut and discharged to the discharge passage 14a, the rice husk M1 having a size smaller than the size of the original rice husk M0 can be obtained.

That is, the rice husk breaking processing apparatus 10 of the present embodiment has the following effects.
(A) Collision at the edge of the through-hole 16 when the rice husk M0 passes through the through-hole 16 by the cooperation of the radially outermost peripheral portion 23 of the rotating plate 22 of the rotating body 20 and the through-hole 16 of the screen 17; Since the breaking process is performed by the fluid shearing action, the size of the rice husk can be reduced in a short time.
(B) Since the rotating plate 22 is not in contact with the screen 17, when the rotating plate 22 rotates, the rotating plate 22 and the screen 17 are not worn in a short time due to friction, and the rotating plate 22 and the screen 17 are not worn. Can extend the lifetime of

<Entire system>
In addition, as shown in FIG. 8, in addition to the rice husk breaking processing device of the embodiment, the rice husk breaking processing device temporarily accumulates the raw rice husk M0 from the rice huller, and the effect of the air blow from the rice huller is broken.
