The present invention relates to a debris screening removal apparatus for collecting only delicacies by completely screening and removing debris (, 米), rice bran, sesa, etc. from polished rice.

White rice, which has been removed from brown rice, is sorted and removed from stone, royal sand, etc. before being quantitatively packaged, and then black, yellow, brown, red, chalk, dark color change through a color sorter. Only the white rice is quantitatively packaged after the rice is screened out.

The white rice packaged through the above process is mixed with crushed rice (strawberry), but the crushed rice cannot be selectively removed by the mason or color sorter.

Recently, in the field of pottery, an attempt has been made to promote the high quality of rice by selecting and packaging only pure white rice, which is mainly left after completely removing and removing the polished rice produced in the rice milling process.

In order to obtain the above perfect rice, it is necessary to remove and remove the chain rice mixed in the white rice before the quantitative packaging, and conventionally, a grain grade sorter as known in the Republic of Korea Utility Model No. 353139 is used.

The grain grading machine supplies and accommodates grain inside the rotating drum, and in the center of the drum, a hopper with a screw conveyor disposed inside is placed in a floating state so that the inlet is always opened upward, The inner circumferential surface has a grooved surface on which a chain can be pinched having a particle size smaller than that of grain, and a screw conveyor for discharging grain is provided in the lower space inside the drum.

The grain grading machine of this configuration is fitted with a debris into the groove of the inner circumferential surface of the drum during rotation of the drum, and separated from the grain by piggybacking on the rotation of the drum. Separation of the tailings is carried out by being separated and accommodated, and the screened tailings are discharged to the outside by the screw conveyor inside the hopper, and the debris removed is discharged by the screw conveyor provided in the inner lower space of the drum. In order to completely remove the debris from the grains, the grains must be held for a considerable time so that the grains contact the inner circumferential surface of the rotating drum. Therefore, the grains cannot be continuously processed, so the throughput per unit time is small.

In addition, the drum is divided into a central part and a lower part, and a screw conveyor, a hopper, and the like are provided so that a complicated structure is formed, which is difficult to assemble.

In addition, there is a problem in that the grain is broken while being in contact with the groove of the inner peripheral surface of the rotating drum to promote the generation of debris.

The problem of the above-described grain grading machine can be solved by screening the grains continuously to remove the debris.

As an example, the shipbuilding machine of the Republic of Korea Utility Model Registration No. 198391 proposed by the present applicant is to screen the sand is added to the grain above the horizontal vibrating screen body, the screen filter, and aspirated to remove black fire, rice husk, etc. by the wind It can be used as a device for sorting and removing debris from cereals.

Accordingly, the present applicant changed the structure of some of the shipbuilding machine, and tried to remove and remove the debris from the grain, and as a result encountered an unexpected difficulty.

The new problem is that as the grain sorting progresses, the screen's eye gets stuck and the eye fills up, so the throughput of grain gradually decreases. Therefore, it is necessary to regularly shut down the device and perform screen cleaning. there was.

In order to solve the above-mentioned problems, the present invention can increase the throughput per unit time by selectively removing the debris through the continuous treatment of the grain through screen filtration, while preventing the debris from being caught on the screen. It is an object of the present invention to provide a new structure for removing the destructive screening device which can accelerate the diffusion and rapidly deconstruct the screening.

The present invention that implements the above object can be implemented to pass through the white rice to the screen body having a mesh scale of the size capable of selecting the chain rice from the white rice so that only the chain rice can be selected.

At this time, if the screen body is rocked in the horizontal direction, as the white rice is widely spread, the chains mixed therein can pass through the screen body, so that efficient screening can be expected.

In addition, when the vibration in the vertical direction is applied to the screen at the same time, the bounding of the white rice is generated, it is possible to screen the tailings more efficiently without clogging the chain tailings into the net scale.

According to the present invention for realizing the above object, a screen frame for accommodating the screen body is disposed on the inner side of the base so as to be suspended on the wire rope so as to vibrate in the horizontal and vertical directions, and the bottom surface of the screen frame is in the horizontal direction. The vibrating wheel causing the vibration and the vibrating motor generating the vertical vibration are respectively disposed at predetermined positions to apply the vibration in the horizontal and vertical directions to the screen frame, so that the white rice supplied through the inlet is diffused to the upper surface of the screen body. At the same time it is bounded and characterized by the configuration so that the chains mixed in the white rice is screened through the screen body.

In addition, the upper end of the steel wire rope is integrally extended with the stopper is supported on the upper side, the lower end extends integrally with the rod having a screw, and the rod has an upper spring seat and a spring and a lower spring It is further provided with a configuration in which a suspension made of a sheet is penetrated so as to suspend the bottom surface of the support plate provided near the four corners of the screen frame, so that the bounding of the white rice performed on the upper surface of the screen body is high and regular. .

Hereinafter, the present invention will be described in detail with reference to preferred embodiments according to the accompanying drawings.

1 is a side cross-sectional view showing the configuration of the apparatus of the present invention, in which the screen frame 4 is inclined inside the base 2, and an inlet 6 for supplying white rice is installed at the upper end side thereof, and the opposite side thereof. At the lower side, the white rice discharge passage 8 and the tail rice discharge passage 10 for separating and recovering the white rice and the stranded rice are attached to the base 2, respectively.

A screen body 12 having a predetermined sieve scale is accommodated in the screen frame 4 so that the white rice can be filtered out and the tailings can be dropped and sorted.

One or two or more of these screen bodies 12 can be arranged in an overlapping phase, and the illustrated embodiment shows a structure in which two are arranged in an overlapping phase.

In the structure in which the two screen bodies 12 are superposed, it is not necessary to interpose the diaphragm 14 between the upper screen body 12 and the lower screen body 12.

The diaphragm 14 collects the drop off by passing through the upper screen body 12 so as not to fall to the lower screen body 12, and guides it to the drop off discharge passage 10.

In addition, the debris which has passed through the lower screen body 12 is guided to the debris discharge passage 10 through the drop opening 16 opened at the bottom of the screen frame 4.

The inlet 6 arranged to supply white rice to the screen body 12 is preferably formed of a branch passage 18 divided into two outlets so that white rice can be supplied to the two screen bodies 12, respectively. Each branch passage 18 is preferably provided with a gate 20 to control the supply of white rice.

By such a configuration, the white rice can be supplied to only one of the upper screen body 12, the lower screen body 12, or simultaneously to both of them.

A vibrating wheel 24 with an eccentric weight 22 attached to the bottom of the screen frame 4 is rotatably arranged via a bracket 26, and driven following the concentric wheel with the vibrating ring 24. The pulley 28 is configured to rotate the vibration wheel 24 by receiving the rotational force of the motor 30 via the belt.

Due to the rotation of the vibrating wheel 24 described above, the screen frame 4 swings in the horizontal direction so that the white rice supplied through the discharge port 6 is widely spread on the upper surface of the screen body 12.

The vibration motor 32 is attached to the bottom of the screen frame 4 in addition to the vibration wheel 24. The vibration motor 32 is to apply the vibration in the vertical direction to the screen frame 4, it is attached by using a suitable bracket 34 so as not to interfere with the vibration wheel 24.

The vibration motor 32 is a motor having an eccentric weight on the motor shaft, and causes vibration by changing the center of gravity by rotation of the eccentric weight.

The vibrating motor 32 allows the screen frame 4 to simultaneously receive the vibrations acting in the horizontal and vertical directions, and the white rice supplied through the inlet 6 is evenly spread on the upper surface of the screen body 12. Bounding caused by

In the device of the present invention, the four edges are suspended with a steel wire rope 36 for smooth and regular vibration of the screen frame 4.

While the screen frame 4 is suspended by the steel wire rope 36, the structure in which the horizontal rocking action due to the rotation of the vibrating wheel 24 appears is not different from that employed in some known shipbuilding machines. When the vertical vibration of the screen frame 4 is applied to such a configuration, the bounding of the white rice diffused to the upper surface of the screen body 12 occurs at a low height, so that the constitution action by the screen body 12 appears smoothly. Will not.

The device of the present invention was able to improve the bounding of the white rice by providing the suspension 36 at the lower end of the steel wire rope 36.

In other words, the steel wire rope 36, as shown in Figure 2, the upper end is integrally extended to the stopper 42 to be supported by a predetermined position on the upper surface of the base (2), the lower end is a rod formed with a screw at the end Since the structure extends integrally with the 44, the rod 44 passes through the support plate 40, and then the upper spring seat 46 and the spring 48 are sequentially extended to the rod 44 extending downward. The lower spring seat 50 is sandwiched and fixed with a nut 52 to form a suspension 38.

As shown in FIG. 3, the suspension 38 having such a configuration supports the bottom surface of the support plate 40 with a spring 48 at four corners of the screen frame 4 to suspend the screen frame 4. Since the screen frame 4 vibrates in the horizontal and vertical directions, in particular, the spring 48 reserves the elasticity while cushioning the vibration force generated in the vertical direction indicated by the arrow direction in the drawing. The white rice bound on the upper surface of the screen body 12 appears to be high and regular, so that no debris is caught in the mesh scale of the screen body 12 so that it is not blocked. Destructive screening will be implemented.

The apparatus of the present invention is not limited to the above-described embodiment, and may be implemented by modifying some structures as shown in FIG.

4 basically has a configuration substantially similar to that of the embodiment shown in FIG. 1, but instead of the vibration motor 32, a belt is connected to a conventional motor 54, and the center is eccentrically supported to vibrate. The only difference is that the vibrating cam 56, which is causing the vibration, is attached to the bottom surface of the screen frame 4.

As described above, the device of the present invention is to simultaneously remove horizontal and vertical vibrations on the screen body having a mesh scale capable of screening the strands, and to remove the strands mixed in the white rice. Since is selected by the constitution effect flowing down while bounding up and down on the upper surface of the screen body, there is an advantage that the screen is screened without being blocked by a declination on the grid.

In addition, since the white rice and the stranded rice to be sorted have a structure which flows down and discharges continuously on the screen body, the continuous white rice sorting process of the white rice is possible, and there is an advantage that the processing capacity per unit time is large.

In addition, since it is based on the structure of a conventionally known shipbuilding machine and has a simple structure in which a vibration motor and a suspension are added thereto, there is also an advantage in that it is easy to design and manufacture.
