The present invention relates to a chaff crushing device that can be used to crush the chaff generated during rice grain processing as a padding material of the barn, or to use as feed and fertilizer raw materials, more specifically, free from the inside of the rotating wheel rotating at low speed The present invention relates to a rice husk crushing apparatus which has a low noise, vibration, dust and power consumption as well as excellent production cost by causing the chaff to be crushed at a low speed by using a rotating grinding roller.

Generally, chaff has poor absorption in natural state without grinding, and fermentation does not progress well, so it is not suitable to be used as raw material of barn material or fertilizer and must be pulverized and used. It is composed of hard shell (fiber and silicon) and is classified as very difficult to grind.

Like raw materials, feedstock can not be used as it is in coarse rice husk, so it can be easily used only by grinding the fiber and silicon components that make up the hard shell by grinding finely.

Such chaff is difficult to grind, so it is conventionally burned to a fire and used as a fertilizer, or it is "swelled" by applying a high pressure and heat with a expander, followed by grinding or using a natural chaff "hamma-mill". High speed grinding machines such as "or" pin-mill "are used to grind finely by rotating them at high speeds of 2,000 to 3000 revolutions per minute.

However, the pulverization methods generate vibration, noise, and dust due to high speed rotation, and electric power of the motor is used a lot, and wear of accessories such as pins or hammers is severe, and thus, motors required for mechanical devices are used. Compared to the power, the output per unit time is small, so the grinding cost is high, and the price of the product (rice flour) is increased, which has the disadvantage of low economic efficiency.

In addition, the chaff swelling method of the chaff is superior in quality than the crushing method, but requires high power for high pressure and high heat, and it is difficult to mass-produce. It was not in.

In addition, a utility model registration application No. 2003-28227 and a patent application No. 2002-20486 have been proposed as a conventional rice husk grinding device for this purpose.

According to the former utility model registration application No. 2003-28227 of the conventional rice husk grinding device, the first hopper 110 that sucks the rice husk through the supply pipe 111, the overall configuration is shown in Figure 1a ); A second hopper communicating with the first hopper 110 by a transfer tube 115 and receiving a rice hull in the first hopper 110 through the transfer tube 115; An impeller 113 for sucking the internal air of the first hopper 110 through the suction pipe 112 and selectively supplying air to the transfer pipe 115; A rotary cutter member 117 mounted to a lower portion of the second hopper 116 to crush the rice hull conveyed from the second hopper 116 by a rotary cutter; Hose-shaped discharge pipe 118 for discharging the chaff powder pulverized in the rotary cutter member 117; consists of the suction chaff through the supply pipe to grind, the chaff to be transferred through the discharge pipe, through the rotary cutter It is designed to crush the chaff.

However, according to the conventional rice husk grinder, the chaff is ground by a rotary cutter, and in order to grind more finely, the chaff is ground while being ground while remaining in the rotary cutter for a predetermined time. Not only does it take a long time, but the supply and discharge pipes for suctioning the chaff into the grinder and the transfer of the crushed rice husk powder are installed together with the grinder, so that the entire grinder volume becomes too large and takes up a lot of working space. Of course, the noise and vibration caused by this had a severe disadvantage.

In addition, according to the latter patent application No. 2002-20486, as shown in Figure 1b, the upper grinding roller connected to the power generating unit consisting of a drive motor and a reducer through a belt and having a rice hull inlet 121 on one side of the upper surface The rotary shaft 123 penetrates 120, the lower grinding roller 122 which is coaxially spaced apart from the upper grinding roller 120, and the center of the upper and lower grinding rollers 120 and 122. It consists of a fixing means for rotatably holding the upper grinding roller 120 with respect to the lower grinding roller 122, between the mill-shaped lower grinding roller 122 and the upper grinding roller 120 which is rotated at a low speed by the drive of the motor The chaff supplied through the hopper is crushed continuously by the mutual friction of the upper and lower grinding rollers (120, 122).

However, according to the conventional chaff crusher, the upper grinding roller 120 to be rotated with respect to the lower grinding roller 122 at a predetermined interval (maintaining a 0.5 ~ 1 mm interval), but it is appropriate to maintain this Because there is no means, the gap of the upper roller 120 can not always maintain the same interval so only chaff around the inlet 121 is pulverized chaff far away from the inlet 121 is difficult to crush This occurred, which also made it difficult to discharge crushed rice husk powder. In addition, when this phenomenon is severe, not only its operation is impossible, but also a problem arises that the friction force due to the mutual compression of the upper and lower rollers (120, 122) can not be expected.

Therefore, the present invention has been made in order to solve the conventional problems as described above, the main object of the present invention is the low speed by using a grinding rotation roller freely rotated in the inside of the rotating wheel of the rice husk generated during rice processing Noise as it is crushed. vibration. In addition to minimizing dust and power consumption, the chaff crushing device to provide a good production cost through this.
