Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an improvement in a massaging roller for a massaging machine.

[Prior Art] Conventionally, a rice milling machine that separates rice into brown rice and chaff has a cylindrical shape that rotates at different rotational speeds in opposite directions and is installed below the rice outlet of a hopper that stores the rice. It is well known that rubbing rubber rollers are arranged horizontally and in parallel with a predetermined gap. A predetermined amount of milled rice is fed from a hopper between these rubber milling rollers, and the milled rice is separated into brown rice and chaff by rotation of the rubber milling rollers.

An example of such a scrubbing machine is shown in FIGS. 3 and 4. The rice milling machine, generally designated by the reference numeral 1, includes a hopper 2 for storing rice, a rubber milling rollers 3, 3' disposed horizontally and parallelly below the hopper, and a stream located below these rubber rollers. an outlet 4 and an outlet 6 connected to the outlet 4
and a blower 7 that blows air into the discharge port 6. The brown rice and rice hulls separated by the rice scrubbing rollers 3 and 3' pass through the outlet 4, and then are sent to the blower 7.
The rice husks are discharged outside from the rice husks discharge port 6 by the wind blown by the machine, and the brown rice falls into the brown rice drop port 8 and is collected.

The rubbing rubber rollers 3, 3' are spaced apart from each other by a predetermined gap and are rotatably mounted.
The ends of the rotating shafts of the rubbing rubber rollers 3, 3' are drivingly connected to each other by gears 5, 5', and the rotating shaft of one rubbing rubber roller 3 is connected to a drive device 9. Therefore, when the rubbing rubber roller 3 is rotated by the drive device 9, the other rubbing rubber roller 3' is rotated in the opposite direction. Further, the numbers of teeth of the gears 5, 5' are different, and the rotational speeds of the rubbing rubber rollers 3, 3' are different. Therefore, the milled rice placed on the scrubbing rubber rollers 3, 3' is subjected to a scrubbing action and is separated into brown rice and chaff. In addition to the rice scrubbing machine having the drive device 9 as described above, for example, there is also a small main drive type rice scrubbing machine for sample testing described in Utility Model Publication No. 35-7348, but it uses rubber rollers and has a different gear ratio. The details are the same as those described above.

[Problems to be solved by the invention] The above-mentioned conventional rice husks require a wind selection mechanism including a blower if they are equipped with a drive device, and if they are hand-cranked, the rice husks and brown rice are separated. Since the particles fall in one place without being separated, they must be separated manually.

[Means for Solving the Problems] The present invention provides a massaging machine having a massaging roller mechanism that can simultaneously perform massaging and sorting operations.

Therefore, the massaging machine according to the present invention is a massaging machine including a pair of massaging rollers arranged horizontally and in parallel, and the pair of massaging rollers have a corrugated surface, and one of the massaging rollers has a corrugated surface. The surface of one scrubbing roller has a right-handed thread, and the surface of the other scrubbing roller has a left-handed thread. A pair of massaging rollers are connected by a transmission mechanism and rotate in opposite directions at a rotation ratio of 1:1.

[Operations and Effects] In the structure of the present invention, the rice is separated into brown rice and chaff, and at the same time the brown rice is moved in the length direction of the rollers, and the rice chaff is caused to fall between the rollers.
Therefore, the brown rice can be collected at the end of the roller mechanism, and the rice husks can be accumulated below the roller mechanism or stored in a container placed there, which eliminates the need for an extensive sorting mechanism and makes it possible to use hand-cranked rice husks. This eliminates the need for manual separation work. Therefore, the overall structure of the graining machine can be made smaller.

[Example] The present invention will be described below with reference to FIGS. 1 and 2 of the accompanying drawings.

Referring to FIG. 1, the massaging roller mechanism according to the present invention has a pair of massaging rollers 10 arranged horizontally and in parallel, and each massaging roller 10 has a metal core (not shown) and A resilient but relatively hard material covering the core, such as hard rubber,
A surface 11 of polyurethane rubber or the like is included. This surface 11 is formed in a corrugated helical shape, with the surface of one of the scrubbing rollers having a right-handed helical shape and the other surface having a left-handed helical shape. The spacing between the paired rice scrubbing rollers 10 is such that rice husks pass through, but brown rice does not pass through, and they are arranged so that their peaks and valleys interlock with each other.

Each of the scrubbing rollers 10 has a gear 12 at its end.
and these gears mesh with each other,
Its gear ratio is 1:1. Therefore,
When one massaging roller 10 is rotated by a drive device or a manual handle (not shown),
These massaging rollers 10 rotate in mutually opposite directions at the same rotational speed as shown by arrow B.

Such a rice husking roller 10 is placed under the hopper 2 as shown in FIG.
When the rice is fed in near one end, the rice graining roller 10 has a screw-like shape, so that the grained rice is transferred to the graining rollers as shown by arrow C in Figures 1 and 2 by an action similar to a screw conveyor. 10 gears 1
2 toward the opposite end. On the way, the rice is subjected to the massaging action of the massaging rollers 10, and the rice husks are drawn in the direction of arrow D by the friction of the rollers, and the rice is removed and becomes brown rice. Only the brown rice remains on the rice scrubbing rollers 10, and the rice husks fall to the bottom of the rollers. Thereafter, the brown rice remaining on the massaging roller 10 is moved to arrow E by the feeding action of the massaging roller 10.
carried in the direction of Here you can collect brown rice appropriately.

In this embodiment, the transmission mechanism is explained as a gear, but a belt hook pulley mechanism or the like can also be applied. Moreover, the corrugated screw-shaped massage rollers are (1) covered with an elastic body as in the embodiment, (2) made entirely of metal, and (3) one roller coated with an elastic body.
It is conceivable that the other one be entirely made of metal. In practical tests conducted by the present inventors, particularly in cases (1) and (3), it is possible to remove the immature grains contained by selecting the hardness of the elastic body and the gap between the rollers.
