The rock portion 200 is located at a lower portion of the rocker 10, that is, below the rock portion 100. The rock portion 200 is formed by removing a raw material from a raw material, stone, and residual foreign matter falling from a wind- It removes the remaining stones and foreign bodies.

Hereinafter, each configuration will be described in detail.

The straight line portion will be described with reference to Figs. 2 and 3. Fig. FIG. 2 is a schematic view for explaining a mechanical operation method of a straight line portion according to an embodiment, and FIG. 3 is a schematic view for explaining a connection relation of related components and inner spaces in the straight line portion according to FIG.

The straight line section (100) includes a straight line section (120). The fixed-line housing 120 has a predetermined space formed therein and is inclined in the longitudinal direction. In particular, it is preferable that the bottom surface 125 of the right-angle housing 120 is formed in an inclined shape.

The primary housing 120 forms a space into which the main raw materials including foreign matter to be introduced through the input unit 110 can be input. The lowest portion of the inclined bottom portion 125 of the right selection housing 120 is formed with a first outlet 126 penetrating downward.

The supporting part 104 is formed in a downwardly extending shape at the lower end of the right part housing 120 and is connected to the frames 101 and 102 extending from the upper part of the staking part to be described later. At this time, an elastic support portion 105 is provided between the support portion 104 and the frames 101 and 102. The resilient supporting portion 105 functions to support the right-angled housing 120 so that it can vibrate itself, and minimizes the transmission of vibration of the right-angled housing 120 to the seating portion.

A vibration motor (103) is provided on one side of the straight line housing (120). The vibration motor 103 vibrates the right-angled housing 120 so that the selection process can be performed more easily.

A belt portion 122 and a first porous plate 124 are provided in the proper-part housing 102.

The first porous plate 124 is provided at a predetermined height from the bottom surface 125 of the right part housing, and a plurality of eyes having a predetermined size penetrating in the vertical direction are formed. The raw material, stone (various sizes) and foreign substances inputted through the inlet 110 are first placed on the first porous plate 124, and then the raw material, the stones and the foreign substances smaller than the above-mentioned eye size are introduced into the first porous plate 124 to fall down. The dropped main material, stones, and foreign matter are moved to the first discharge port 126 along the slope of the bottom surface 125.

The second porous plate 1251 has a smaller eye size than the first porous plate 124 and is formed to have a larger eye size than the main raw material. That is, in consideration of the distribution of the diameters of the raw materials, those having larger diameters are removed through the first porous plate 124, and those having a smaller diameter are removed through the second porous plate 1251. The lower part of the second porous plate 1251 may be connected to the second separation pipe 143.

The belt portion 122 is provided inside the straight portion housing 102. The belt portion 122 rotates via two parallel line rollers. At this time, it is preferable that the longitudinal direction of the belt portion 122 is parallel to the first porous plate 124 described above.

And a plurality of cut-off portions 123 are formed on the outer side of the belt portion 122 so as to protrude. The attracting portion 123 sweeps the upper surface of the first porous plate 124 through the belt portion 122 via the straight rollers 121 during one week.

 A wind power selector 141 is provided below the first outlet 126. The wind force sorting unit 141 forms a space in which stones and residual foreign matter falling from the first discharge port 126 of the right selection unit 100 are temporarily housed. At the lower end of the wind force discriminating part 141, a second outlet 142 communicating with the contents temporarily stored in the wind force discriminating part 141 is provided so as to be able to drop gravity. In addition, a second separation pipe 143 is provided on one side of the wind power sorting unit 141 so that relatively light foreign matter can be moved and discharged according to low pressure suction of the suction unit, which will be described later.

On the other hand, the large stones and foreign matter that have not been passed through the first porous plate 124 and swept down by the attractor 123 are discharged from the lowermost portion of the first porous plate 124 through the first separator 130 to the outside .

The seat portion will be described with reference to Figs. 4 and 5. Fig. FIG. 4 is a schematic view for explaining a mechanical operation method of a stave portion according to an embodiment, and FIG. 5 is a schematic view for explaining a connection relationship between the structural portions and the inner spaces of the stave portion of FIG.

The seat portion includes a porous separating plate 220 and a suction portion 213. The porous sorting plate 220 is provided in an inclined plate shape and is pivoted by the sorting cam portion 263 operated by the first motor 261. The sorting cam unit 263 may be implemented using at least one cam and camshaft or the like so that the porous sorter plate 220 is swung up and down and left and right according to the rotation of the first motor 261, It is possible to select the specific gravity of the main raw material and the foreign materials which are seated on the upper part. At the same time, the suction unit 213 is sucked so that a low pressure state, that is, a vacuum specific gravity can be selected. In this case, scattering of foreign matter is minimized, and removal of such foreign matter is easier than the conventional method in which low specific gravity is levitated by applying wind force. In addition, by performing the composition of the non-specific gravity environment and removing the foreign objects simultaneously, it is possible to perform an efficient operation and to improve the removal efficiency of stones and foreign bodies.

At this time, the residual stones having a relatively large specific gravity are moved upward along the inclined surfaces, temporarily stopped at the upper part of the porous sorting plate 220 by the opening and closing part 222, and then discharged through the residual collecting part 230. The raw material, that is, the grains from which the foreign substances are removed, is moved downward along the slope of the porous sorting plate 220, and then recovered through the grain grainy outlet 240.

Scattering of dust or the like may occur from the main raw material and foreign matter falling through the second outlet 142 of the wind power selector 141. In order to prevent such scattering, a scattering preventing portion 211 covering the periphery of the second outlet 142 may be provided.

On the other hand, the suction unit 213 is sucked by the fan 262 operated by the first motor 261 in a low pressure suction manner. At this time, the suction unit 213 sucks and removes relatively light foreign substances or dust from the side surface of the wind power sorting unit 141, and is connected to the side surface of the scattering prevention unit 211 to create an environment for each non-specific gravity Inhale and remove any light foreign objects or debris.

In addition, the porous sorter plate 220 may further include a hopper 250 for receiving dust falling down to the lower portion of the porous sorter plate 220.

Referring to FIG. 6, a general operation method of the stoner according to the embodiment will be described. FIG. 6 is a schematic view for explaining an overall operation method of a stoner according to an embodiment.

Foreign matters such as main raw materials, stones (large stones, common stones and stones) and straws inputted through the inlet 110 are first deposited on the first porous plate 124, The common stones, residues, and foreign matter fall down through the first porous plate 124 and then move to the first outlet 126 along the slope of the bottom surface 125. The large foreign matter A2 such as large stones and straws that have not been able to pass through the first porous plate 124 and swept down by the attracting unit 123 are discharged from the lowest portion of the first porous plate 124 to the first separating pipe 130 to the outside. Meanwhile, in the process of moving to the first outlet 126 along the inclination of the bottom surface 125, the second perforated plate 1251 having a smaller eye size than the first perforated plate 124, Those having a small particle size are separated into the second separation pipe 143.

The raw materials and the residues stuck in the porous sorting plate 220 via the wind power sorting unit 141 are separated by specific gravity sorting. At this time, the regular stones A4 having a relatively large specific gravity are moved upward along the inclined surface, and then discharged through the residual collecting portion 230. The raw material, that is, the grains from which the foreign substances have been removed, is moved downward along the slope of the porous sorting plate 220, and is recovered through the grain grainy outlet 240.

The suction portion 213 is connected to the side surface of the wind power selector 141 and the side surface of the scattering prevention portion 211 to suck and remove light foreign matter or shedding portions A3. On the side of the wind force discriminating portion 141, dust, light foreign matter, etc. are removed by sucking in the suction portion 213. In the case of the second suction pipe 212, it is a main object to provide an environment for specific gravity selection, but it is also possible to remove floating matters such as dust in the shatterproof portion 211, which are light in weight.

Dust falling down to the lower portion of the porous separating plate 221 and small-sized stones (concretely, clay-like and small-sized intermediate stones) A6 and the like can be collected and discharged through the hopper 250 .
