Description

  The present invention is a pulverizing apparatus in which rice husks dehulled by a hulling machine are charged automatically or manually and cut into sawdust.

  Until now, rice husks have been sprinkled in fields and rice fields, but they are difficult to rot and are difficult to process. However, at present, crushing rice husks makes it easy to contain moisture, enables fermentative decomposition in an aerobic environment, and has opened a field of use that can be used in place of livestock litter. Moreover, since the capacity | capacitance of a rice husk can be reduced by grind | pulverizing, the place to store can be reduced and it has become easy to carry.

  In response, various rice husk grinders have been developed. For example, a large rice husk grinder that can directly grind in cooperation with the hulling machine needs to be ground, so it can be used for motor power. The cost is high and the machine body is very expensive. In addition, the rice husk pulverizer using a high-speed rotating pulverizing blade developed for downsizing has a risk that the blade is worn out and easily damaged.

Some conventional rice husk pulverizers pulverize while crushing while being pressurized by a screw-type pulverizer (for example, Patent Document 1). In addition, there is a type in which rice husk pulverization is performed by a pulverization blade that rotates at high speed in a pulverization chamber (for example, Patent Document 2).

  In the crushing of rice husks, ideally, it is desirable to cut the longitudinal fibers of the rice husks, and for this purpose, it is necessary to cut the rice husks while supplying them in tandem. That said, it is impossible to rearrange and cut 100% of the myriad overlapping rice husks vertically, but the inventor can approach the ideal in one or two steps. I decided to do the development.

  In order to achieve the above object, the present invention firstly rotates the cutting tool provided on the rotor 3 close to the receiving tool provided on the rice husk pulverizer body, and closes to the upper surface cutting edge of the receiving tool. Further, the gist is provided with a rice husk cascade supply plate having a number of longitudinal grooves.

  Secondly, a main body cover with a slightly wide upper part of the rice husk crusher is provided, and a plurality of wind pressure adjusting partition plates are attached to the upper part of the inside so that the angle can be adjusted from the outside, and the rice husk is supplied to the upper part of the cover. The gist is that the machine 17 is provided.

  Thirdly, the gist is that the stirring plate 6 is provided upright on the cutting edge provided in the rotor 3 that rotates at high speed close to the receiving edge provided in the main body.

  The rice husk supplied from the separator 17 can be adjusted at a preferable supply speed by adjusting the angles of the plurality of wind pressure adjusting partition plates. In response to this, the rice husk is sequentially sent to the rice husk cutting portion adjacent to the cutting blade and the receiving blade. In the final phase, the rice husk tandem supply plate is constituted by a large number of vertical grooves. Since the vertical grooves provided in the rice husk vertical supply plate are configured to be shorter than the vertical diameter of the rice husks and longer than the horizontal diameter, the rice husks passing through the grooves are arranged in tandem with the tip of the receiving blade. It is led to the rice husk cutting point.

  Even if the rice husks cut in a row are not cut in half, they cut at least across the rice husks, so naturally the fibers are shorter than jumping randomly into the husk cutting points. Will be disconnected.

  Therefore, since the pulverized rice husk can be finely pulverized, the bulk is reduced to 1/2 to 1/3 compared with before pulverization. In addition, since the pulverization is a method of cutting with a thick blade, the blade is less consumed and hardly damaged, and re-polishing is simple and economical.

  The stirring plate 6 attached to the rotor 3 causes a vortex air flow by the rapid rotation of the rotor 3, and increases the discharge power of the fine rice husks from the screen metal mesh 13, while repeatedly stirring the uncut rice husks. Demonstrates the ability to circulate to the cutting point.

  The best mode of the present invention will be described below.

  FIG. 1 is an explanatory view showing an embodiment of the rice husk pulverizer of the present invention, and FIGS. 2 and 3 are mainly explanatory views of the main part of the invention. The rice husk crushing device installed on the pedestal 1 is attached to the center of the main body support base 2 with a space that allows the rotor 3 to rotate, and is rapidly rotated by the motor 4. The rotor 3 is provided with a plurality of cutting tools 5 and an agitating plate 6 slightly upright behind the cutting tools 5, and the main body support 2 is provided with a receiving tool 7 adjacent to the rotating cutting tool 5. Are provided in two places.

  A rice husk cascade supply plate 8 having a large number of longitudinal grooves is provided in a slightly inclined manner near the upper surface cutting edge of the receiving blade 7. As shown in FIG. 3, the rice husk tandem supply plate 8 has a plurality of thin partition plates 9 projecting in parallel to form a rice husk guide groove 10, the interval of which is shorter than the vertical diameter of the elongated rice husk. The width is longer than the diameter, and the width of the groove is such that the chaff can pass easily vertically but not horizontally. It is ideal that the rice husk tandem supply plate 8 is made of a hard resin having good sliding properties and is a groove having a slightly round shape.

  The tip 11 position of the rice husk tandem supply plate 8 is attached so as to cover a part of the tip, and a rice husk guide plate 12 is provided so as to be curved so as not to contact the rotating blade. Both the rice husk guide plate 12 and the rice husk column supply plate 8 function as if guiding fine grains with a funnel, and the rice husk once contained is always provided by the rice husk guide groove 10 provided in the rice husk column supply plate 8. Then, it is guided substantially to a rice husk cutting portion where the receiving blade 7 and the cutting blade 5 are close to each other in a column.

  In addition, a screen wire mesh 13 is provided inside the main body support 2 along a curved surface that is several centimeters away from the rotational surface of the cutting edge 5 of the cutting blade 5 provided on the rotor 3 so that the crushed rice husks can be screened. Like that.

The main body support 2 is provided with a main body cover 14 having an upper portion of the rice husk pulverizer that is slightly wide. A plurality of wind pressure adjusting partition plates 15 are attached to the upper portion of the main body support base 2 so that the angle can be adjusted from the outside. Above the main body cover 14, a rice husk inlet 16 is provided, and a separator 17 for supplying rice husk is provided.

By crushing rice husks, it becomes water-containing and can be used in place of sawdust. It can also be used to adjust the moisture in livestock litter and compost.
