Description

Rice polishing machine

More particularly, the present invention relates to a grinding machine for grinding a grain in a grain such as rice, barley, trowel and the like, more specifically, The present invention relates to a polishing machine capable of suppressing a decrease in the moisture content of the grain caused by heat generated in the process of peeling off the grain, and performing repetitive grinding operations according to the kind of grain.

Generally, 搗精 refers to the work of peeling the bran layer of ungerminated grain from grain such as rice, barley, etc., and grinding rice and barley which are used for rice grain largely Can be categorized as a venom machine.

That is, since the rice husk is easy to separate the husk, it is used to obtain the rice after peeling off the rice husk through the brown rice machine. In the venous machine, as compared with the rice, the cheek layer of the barley Are combined to form a thick steel layer, so they are used to obtain a vein without going through a microscope.

However, in recent years, the increase in rice production, which is the main source of food, has led to the establishment of rice mills and rice paddies, which have relatively low production yields compared to rice. Mostly.

As a method for grinding the grain, there are a horizontal type cylindrical friction type in which the grains are caused to friction and charge action by the resistance of the weight, a vertical type grinding type in which the gold steel abrasive rollers are rotated at a high speed in the rolling part, The weight of the grains in the grains and the resistance of the rising sphere are used to induce a charring action and a friction action, and an automatic circulation type stirrer of a steel grinding wheel installed to be able to rotate around a fixed shaft on a steel plate A rotating electric type in which rice is grinded and grinded by a steel grinding wheel by rotating a grinding wheel, a mortar-type grinding machine in which a mortise ball is stepped on by hand or by grasping with a hand, and a spiral made of iron is rotated at the center of the mortar to circulate the grains There is a stomach cutting and an eel.

Among them, in Korea, there are a horizontal type cylindrical frictional type in which a sugar roll having a stirring streak is rotated on a surface in a jar, and the sugar layer on the surface of the rice is removed by frictional force acting between the grains, There are many types of vertical grinding equipments which are used mainly for processing solid grains such as barley or the like.

Particularly, the conventional vertical type grinding type polishing machine has a main shaft which is vertically long and rotated about the axial direction to remove the steel layer of the grain fed from the upper side, and a main shaft which is coupled to the outer surface of the main shaft and rotated together with the main shaft A clearance adjusting member for adjusting a clearance in a cylindrical plain room provided at a predetermined interval around the periphery of the grinding roll, a screen provided between the gap adjusting member and discharged through a grinding roll, And an outlet through which grains with the steel layer removed are discharged.

At this time, a large amount of grains put on the upper side are fed to the upper side by the conventionally known Japanese Laid-Open Patent Application No. 2015-44140 (grinding type vertical squeezing machine) and Korean Patent Laid-open No. 10-2015-0059832 (vertical and friction type squeezing machine) A plurality of grinding rolls are stacked on the outer surface of the main shaft in a stacked manner so as to increase the production amount by removing the steel layer by grinding work.

However, in the above-mentioned prior art techniques, the grinding roll is smoothly grinded by the load of the grain fed from the upper side of the grinding roll coupled to the main shaft, but the space between the grinding roll and the gap regulating member removes the grain layer The grains on the upper side stay in a stagnant state until the steel layer is removed and the grains are moved to the outlet on the lower side and the work speed is slowed down. In order to increase the work speed, When the pressure is increased, there is a problem that the grain is crushed or damaged by the grinding roll on the upper side, and the product value is lowered.

In addition, when the barley is sown through one rinse machine, at least three or more squeezing operations must be performed in comparison with the rice. However, as the operation speed slows down as described above, there is a problem that the production efficiency is lowered further.

In order to allow the support table 300 to repeat the drawing process depending on the type of grain fed into the hopper 10 or to be transported to a subsequent process, The first distribution port 321 and the second distribution port 322 formed on both sides of the distribution pipe 320 are formed so as to be opened to one another and to be closed Adjustment means 330 are provided.

At this time, the end of the first branching port 321 is provided so as to feed the grain fed to the first feeding means 510 for feeding the grain to the hopper 10, and the end of the second branching port 322 And is supplied to the second conveying means 520 which feeds the rolled corn grain to a subsequent process, that is, a stirrer.

The reason that the distribution pipe 320 and the position adjusting means 330 are provided is that the grain is removed by one or two grinding processes in the case of a grain having a thin layer of grain such as rice, In case of the grain constituting the steel layer, since the steel layer is removed by the rolling process of 3 to 4 times, it is intended to allow the repetitive rolling process to be performed through one polishing machine.

On the other hand, in order to perform the repetitive grinding process through the polishing machine, the grinding tube 320 and the position adjusting means 330 are provided. In order to transfer the grinded grain discharged from the discharge port 270 to a predetermined position, The feed pipe 340 is connected to one side of the feed pipe 300 and fed to the elevating means 530 which is disposed between the rice pan and the rice pan and is fed to a subsequent process, A first supply pipe 531 for supplying the grain to the inside of the hopper 10 coupled with the polishing machine on the upper side of the elevating means 530 and a second supply pipe 532 for supplying the grain to the sinker side, Closing means 533 for opening one of the first supply pipe 531 or the second supply pipe 532 and closing the other may be provided.

It is necessary to generate a rotational force large enough to rotate the rotating body 210 to which the plurality of grinding members 230 coupled to the rotating body 210 are coupled so that a pulley is provided at the lower end portion of the rotating body 210 as in the first embodiment And a motor is installed on one side of the support table 300 so that the drive shaft and the pulley of the motor are connected by a plurality of belts to be driven.

Hereinafter, the operation of the rinse machine constructed as above will be described.

When the grains of the grain fed into the hopper 10 are fed to the inlet 110 or before the grain is fed into the hopper 10 and the feed is controlled through the feed rate control lever 140 in the open region of the slide groove 113 The supply amount regulating plate 130 coupled to the rotation protrusion 112 is moved to regulate the open region of the charging port 110. The grains supplied to the division supplying portion through the opened region are distributed to the distribution plate 121, Lt; / RTI >

The kernels that have passed through the divided feed section are supplied from the upper side to the supply guide screw 220 through the guide hole 150 having a predetermined curvature toward the supply guide screw 220. In this state, The grinding member 230 coupled to the rotating body 210 is rotated and the surface of the grain is ground while the grinding member 230 is rotated to remove the steel layer.

Particularly, since the grinding member 230 provided adjacent to the lower side of the supply guide screw 220 coupled to the rotating body 210 is formed such that the upper outer circumferential surface thereof is inclined at a predetermined angle, it is possible to easily insert the grain, The rotating body 210 is detachably coupled to the outer circumferential surface of the rotating body 210 through the connecting means 233 and separated by the plurality of grinding wheels 231. However, As the rotor rotates, the frictional heat generated during the removal of the steel layer of the grain can be cooled through the wind that is discharged to the space between the separators.

In addition, since the supply guide screws 220 are provided on the upper side of the grinding member 230, which are respectively disposed on the upper and lower sides of the rotating body 210, the grains through the supply guide screw 220 are ground So that the grain of the grain can be easily removed and the grain can be easily moved toward the outlet 270 while the steel layer is removed.

At this time, it is possible to control the degree of removal of the steel layer of the grain by adjusting the distance between the moving frame 243 and the grinding member 230 through the gap adjusting lever 241, This is because the grain moving downward will be shattered as much as it can pass through this separation distance.

After the movement distance of the movable frame 243 is adjusted by the operation of the gap adjusting lever 241, the fixed lever 245 is operated so that the end of the fixed lever 245 presses the movable frame 243 The movable frame 243 can be maintained in a fixed state while the steel layer of the grain is removed by the lower surface grinding member 230, so that more efficient grinding can be performed.

External air flows into the space between the discharge screen 250 and the upper body 280 through the air supply hole 281 and a plurality of suction units 261 And a discharge unit 310 capable of sucking air between the discharge screen 250 and the upper body 280 is coupled to one side of the support table 300 so that suction force Can be discharged through the discharge screen 250 between the discharge screen 250 and the upper body 280 and the discharged steel layer can be discharged to the outside through the discharge means 310 or discharged It can be.

When the air supply hole 281 is fully closed by operating the air supply adjusting lever 283 provided in the upper body 280, the area between the discharge screen 250 and the upper body 280 becomes a vacuum state, The steel strip removed from the grain is not sucked efficiently, and if the feed hole 281 is operated to be completely opened, the steel strip that has been excessively inflowed from the outside can not be efficiently sucked out of the grain, .

The grain removed while the steel layer removed from the grain is discharged by the discharge means 310 through the discharge screen 250 is collected into the discharge port 270 and the discharge pipe 320 is connected to the support table 300, And the position adjusting means 330 may be provided to control the position of the position adjusting means 330 according to the kind of the grain and the state of the grain so that the position adjusting means 330 is supplied to the first feeding means 510, The conveyance pipe 340 may be provided on the supporting table 300 and the opening and closing control means 533 provided on the elevating means 530 may be provided By supplying the first supply pipe 531 and the second supply pipe 532 selectively, the drawing process can be repeated or a subsequent process can be performed.

In this case, when the weight is coupled to the opening / closing part of the discharge port 270, the weight can be discharged downward when the weight is set, so that the desired weight can be sent to the subsequent process or repeatedly transmitted. It can be determined whether or not the steel layer has been properly removed from the rolled grain of the state, and it is possible to obtain a time for repeating the drawing process or judging whether to proceed to a subsequent process.

As described above, according to the present invention, it is possible to smoothly feed the grains fed from the upper side downward, to easily peel only the steel layer without damage such as crumbling or crushing, to efficiently separate the peeled steel layer and the ground grain And a grinding member 230 in which a plurality of grinding wheels 231 are coupled to the lower side of the supply guide screw 220 are provided, It is possible to obtain the same effect as that obtained by performing the two rounding process through

It is also possible to easily perform the installation and maintenance by detachably attaching the grinding member 230 to the outer surface of the rotating body 210. By rotating the rotating body 210, By allowing the wind to be discharged from the spaced space, frictional heat generated during the removal of the steel layer of the grain introduced from the upper side by the grinding member 230 can be cooled, so that the inherent moisture content of the grain can be reduced or deformation of the outer shape can be prevented Thus, there is an effect that the merchantability can be preserved and the product reliability to the customer can be increased.

In addition, according to the kind of grain, the grain which is grinded through the grinding machine can be supplied to the subsequent process or controlled again through the grinding machine, so that the efficiency of the work is increased, and even if the grinding machine is not enlarged, There is an effect to be saved.

Hereinafter, a polishing machine according to a second embodiment of the present invention will be described with reference to FIG.

The grinding member 230 according to the second embodiment is provided with two grinding members 230 on the lower side of the supply guide screw 220 and is coupled to the outer surface of the rotating body 210 in a stacked shape. .

The grinding member 230 is formed such that the rim portion of the upper portion adjacent to the grinding member 230 located on the upper side of the rotating body 210, that is, the supply guide screw 220 is formed to be inclined downward, 230 may not have separate inclined portions.

The reason for this is that, in the case of the grinding member 230 positioned on the upper side, the grain supplied from the supply guide screw 220 can be easily drawn through the inclined portion, but when the grain is supplied through the grinding member 230 on the upper side The same effect as that of the inclined portion of the grinding member 230 located on the upper side can be expected even if the inclined portion is formed on the grinding member 230 located on the lower side since the grinding member 230 has already been moved to the outer peripheral side of the grinding member 230 It is preferable to form an inclined portion only on the upper side of the grinding member 230 in order to suppress an increase in cost due to additional processing.

The grinding member 230 having the plurality of grinding wheels 231 radially coupled to the lower side of the supply guide screw 220 is stacked up and down so that the grinding member 230 is more By further widening the range to be ground, the steel layer of the grain can be removed more effectively, and an advantage such that two or more grinding processes are carried out through one polishing machine can be obtained.

Further, even if the number of the grinding members 230 is increased, the frictional heat generated during removal of the steel layer of the grain by the wind provided through the spacing space between the grinding grindstones 231 is effectively lowered, And the deformation of the outer shape does not occur.

The scope of the present invention is not limited to the above-described embodiments, but may be embodied in various forms of embodiments within the scope of the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
