DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a litter for a livestock breeding animal, particularly cattle and pigs, a feed additive for promoting the intestinal action of cattle, and a soil base for artificial culture for horticultural rearing. The present invention relates to an apparatus for efficiently processing “crushed rice husk” used for materials and the like.

[0002]

2. Description of the Related Art Rice straw, sawdust and the like are used as litter on the floor of a stall where cattle and pigs are bred in order to reduce contamination by livestock excrement. Accordingly, it has become difficult to obtain these litters. Rice husks are used as a substitute for the effects of these litters, but rice husks that have been threshed are inferior in water retention and hygroscopicity. As a means for achieving this, the inventors have provided a rice husk crusher having one crushing rotary blade.
(Japanese Patent Application No. 10-265592)

[0003]

The rice husk crusher provided has one crushing case and one crushing rotary blade, and each step of raw husk input → closing shutter closing → crushing → discharge shutter opening → discharge. Although automatic repetition is continued, labor-saving automatic operation is possible, but it is insufficient to obtain a larger amount of pulverization capacity because the pulverization process is interrupted.

[0004]

In order to solve the above-mentioned problems, in the present invention, a supply device for continuously feeding a fixed amount of raw rice hulls into a primary grinding chamber is provided for the purpose of completely continuous grinding. Connect to the input port.

In the primary grinding chamber, a primary grinding blade which is rotated at a high speed by a drive source such as a motor is provided, and a secondary grinding chamber sharing the same space as the primary grinding chamber is arranged in a stepwise manner.
The secondary crushing blade is also rotated at the same rotation speed as the primary crushing blade in the secondary crushing chamber.

[0006] An outlet for discharging the crushed fine rice hulls is provided at the bottom of the secondary crushing chamber, and the outlet is provided with an outlet adjusting shutter.

[0007] While the raw rice hulls are quantitatively and continuously supplied from the input port of the rice hull crusher having the above-mentioned configuration and passed through the primary crushing chamber and the secondary crushing chamber, the rice hulls are crushed by the primary crushing blade and the secondary crushing blade. The crushed and crushed rice hulls in the crushing chamber are adjusted by adjusting the opening degree of the discharge control shutter to adjust the residence time of the crushed rice hulls in the crushing chamber.

[0008]

In the rice husk crusher according to the present invention having the above-described structure, the raw rice hull continuously supplied from the input port is crushed and crushed by rotation of the primary crushing blade in the primary crushing chamber. It moves in the same space and moves into the secondary crushing chamber, where it is further crushed and crushed by the secondary crushing blade.

The migration of the rice hulls during the crushing from the primary crushing chamber to the secondary crushing chamber located in a stepwise lower stage is performed by the high speed of the primary crushing blade in the primary crushing chamber and the secondary crushing blade in the secondary crushing chamber. The fine rice hulls, which are realized by the centrifugal force due to rotation and the eddy current of the air in the space and are crushed to increase the specific gravity, are discharged from the discharge port, and maintain a state of a low specific gravity because they are not yet crushed. The rice husks are returned to the primary crushing chamber on the air vortex and merge with the uncrushed rice hulls passing through the primary crushing blade and the secondary crushing blade.

[0010] The finely hulled rice hulls are discharged from the discharge port, and when the opening area of the discharge port is reduced by operating the discharge control shutter provided adjacent to the discharge port, the discharge amount is suppressed. Therefore, the time during which rice hulls stay in the primary and secondary crushing chambers is lengthened, and the number of circulations is increased, so that the fine particle size can be further reduced.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described below in detail with reference to the drawings. Referring to FIG. 1, the rice husk crusher according to the present invention is configured such that raw material hulls C are supplied to the input port 1 quantitatively and continuously by a screw transfer device or another appropriate supply device 11. Reference numeral 1 denotes an opening and communicates with the primary pulverizing chamber 5 below the inlet 1.

The bottom plate 51 of the primary crushing chamber 5 is
On the way, the secondary crushing chamber bottom plate 61 of the secondary crushing chamber 6 is bent in the vertical direction and extended again in the horizontal direction to form a step-like structure.
And a cylindrical outer periphery that maintains an appropriate gap on the outer peripheral edges of the primary crushing chamber bottom plate 51 and the secondary crushing chamber bottom plate 61 so as not to hinder the rotation of the primary crushing blade 3 and the secondary crushing blade 4. The plates 52 and 62 are fixed, so that the primary crushing chamber 5 and the secondary crushing chamber 6 share a common space 53.

The bottom plate 51 of the primary crushing chamber and the bottom plate 6 of the secondary crushing chamber serving as the bottom surfaces of the primary crushing chamber 5 and the secondary crushing chamber 6, respectively.
1, the primary grinding blade 3 and the secondary grinding blade 4 rotating in the same direction at a high speed are supported by the common drive motor 8 via the V-belt 81 or an appropriate conductive means instead of the V-belt 81. The primary crushing blades 3 and the secondary crushing blades 4 are arranged in a stepwise manner with their turning radii overlapping.

In the present embodiment, the shapes of the primary crushing blade 3 and the secondary crushing blade 4 and the outer peripheral speed during rotation are set to a straight single blade, and the outer peripheral speed is set to 90 m / sec. However, as long as the function of the present invention is not impaired, it is possible to arbitrarily change various conditions such as a shape, an outer peripheral speed, and a method of rotational driving, and any of these changes is included in the rights of the present invention. The implications are obvious.

The raw rice hulls C charged into the primary grinding chamber 5 are:
Impacted by the rotation of the primary crushing blade 3 rotating at high speed,
Cut, crushed and crushed.

The crushed rice hulls C ′ are mixed with the primary crushing blade 3.
After moving to the secondary crushing chamber 6 along the centrifugal force accompanying the rotation of the air and the flow of the air vortex generated in the space 53 due to the rotation of the primary crushing blade 3 and the secondary crushing blade 4, The crushing and crushing are further repeated by the secondary crushing blade 4 rotating at a high speed in the crushing chamber 6.

The fine rice hulls C ″ thus crushed and pulverized into fine particles have a higher specific gravity than the crushed rice husks C ′, and thus accumulate below the secondary crushing chamber 6. The rice husk crusher is discharged from the discharge port 2 provided in the bottom plate 61.

In the secondary crushing chamber 6, the fine hulls C ″ of the transferred crushed rice husks C ′ have an increased specific gravity and are discharged from the outlet 2 to the outside of the secondary crushing chamber 6, that is, the rice husk crusher. The crushed rice hulls C ′ which are discharged to the outside but not yet crushed ride in the air vortex formed by the rotation of the primary crushing blade 3 and the secondary crushing blade 4 in the space 53, and It starts to circulate and recirculates into the primary crushing chamber 5, merges with the newly added raw rice hulls C, and reaches the secondary crushing chamber 6 again via the primary crushing blade 3 and the same route as described above. The rice hulls are again pulverized by the secondary crushing blade 4 to become fine rice hulls C ″, and are discharged from the discharge port 2 to the outside of the rice husk crusher.

In the present invention, the outlet 2 is provided with an outlet adjusting shutter 7. The outlet adjustment shutter 7
Has a structure in which the opening area of the discharge port 2 can be arbitrarily adjusted. Therefore, when the opening area of the discharge port 2 is increased, the discharge amount from the secondary grinding chamber 6 increases, and As a result of mixing of the crushed rice husks C ′ in the part, the overall particle size composition of the product husks discharged from the rice husk crusher becomes large, whereas if the opening area of the outlet 2 is reduced, the secondary crushing chamber 6
Is reduced, and the crushed rice hulls C ′ stay in the primary crushing chamber 5 and the secondary crushing chamber 6 for a long time, during which the number of times of crushing by the primary crushing blade 3 and the secondary crushing blade 4 increases. Thereby, the particle size composition of the product chaff becomes fine.

In the description of the preceding paragraph, the amount of fine rice hulls C ″ discharged from the discharge port 2 and the amount of raw rice hulls C newly introduced into the primary grinding chamber 5 from the input port 1 are naturally determined. Meanwhile, the total volume of the space 53 constituted by the primary crushing chamber 5 and the secondary crushing chamber 6 and the total volume of the raw rice hulls C, the crushed rice hulls C ′ and the fine rice husks C ″ that have been charged and continue to perform the crushing operation The amount of discharge from the discharge port 2 and the amount of charge to the input port 1 must be appropriately maintained so that the ratio of (1) maintains an appropriate volume ratio that can continue the crushing operation normally.

In the above-mentioned series of crushing operations, the continuous crushing operation is continuously performed by continuing the quantitative and continuous input of the raw rice husks, so that a large amount of rice husks that could not be realized by the conventional technology can be processed. It became.

In addition, the product chaff having a large grain composition obtained by enlarging the opening area of the discharge port is used as a litter for the floor of the livestock barn, and the medium grain composition or fine grain obtained by adjusting the opening degree of the opening area is used. Product rice hulls with a grain composition are used as a base material for artificial cultivation soil for horticultural rearing and as a feed additive that is effective in promoting intestinal regulation in cattle breeding. The size can be easily selected by adjusting the outlet adjusting shutter.

[0023]

According to the recent changes in the rice production style, it has become difficult to easily obtain rice straw, so that it has become difficult to use rice straw as a litter for livestock floors and to use it as a high quality litter. The use of rice husks has also been emphasized, along with the effect of reusing resources, in response to the situation in which sawdust made of domestic timber, which had been used, becomes difficult to obtain due to the surge in imported timber.

However, rice hulls are difficult to use as a litter in a threshed state, but have poor water retention and moisture absorption properties. For use as a litter, feed additive, base material for artificial cultivation soil, etc. It is necessary to grind the rice husk.

According to the present invention, rice husks which could not be reused can be continuously processed in a large amount at an arbitrary particle size. Contribute across a very wide area, such as by promoting the effect and enabling the effective use of rice crop production by-products such as the creation of value as an additive to livestock feed, the base material for artificial cultivation soil for horticultural seedlings, etc. Is big.
