DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

As shown in Figs. 1 to 3, the grain sorting apparatus 10 for sifting with horizontal and vertical vibrations is provided with a sorter frame 12. The selector frame 12 is stably installed with a plurality of support legs 121 and a pair of swing support plates 122 at the upper portion. In this embodiment, the number of the support legs 121 is four, but the number of the support legs 121 is not limited. The support legs 121 may be interconnected through cross bars or the like, which are not shown but are installed in a horizontal or diagonal direction.

A vibrating bar (14) is supported in the vertical direction on the side of the selector frame (12). In this embodiment, the vibrating bar 14 is made of a long steel having a circular cross section. The vibrating bar 14 may be disposed in at least four places at one or more positions with the upper end inserted into the pair of bar supporting plates 122 and the lower end positioned near the bottom of the selector frame 12. [ In the present embodiment, the vibration rods 14 are provided in one pair for each place. Therefore, a total of eight swinging rods 14 are installed.

The mesh box lower pedestal 16 is suspended at the lower end of the vibrating rod 14. The mesh box lower pedestal 16 is hung horizontally to the vibrating rod 14. The mesh box lower pedestal 16 has a box-like structure.

The mesh box upper pedestal 20 is fixedly arranged via a connecting bar 18 at a predetermined height from the mesh box lower pedestal 14. Therefore, the mesh box lower pedestal 14 is connected to the lower side of the connecting bar 18, and the mesh box upper pedestal 20 is connected to the upper side of the mesh pedestal.

Between the mesh box lower pedestal 16 and the mesh box upper pedestal 20, a plurality of mesh boxes 30 for constituting grains are housed so as to be taken out so as to be layered. The mesh box 30 for constituting a plurality of grains will be described later.

A horizontal vibration motor 40 is fixed to one side of the mesh box lower pedestal 16. At this time, the rotation axis of the horizontal vibration motor 40 is vertically installed. A horizontal vibration eccentric rotation body 42 is rotatably provided at the center of the lower bottom surface of the mesh box lower pedestal 16 and is rotated by receiving the rotation force of the horizontal vibration motor 40. The rotating shaft of the motor 40 for horizontal vibration and the eccentric rotating body 42 are connected via a belt 41. [ The center of gravity of the eccentric rotation body 42 for horizontal vibration is placed at a position eccentric from the center of gravity (center of gravity) of the rotation shaft of the mesh box lower pedestal 16.

Therefore, when the horizontal vibration motor 40 is rotationally driven, the eccentric rotation body 42 rotates away from the center of the rotation axis of the mesh box lower pedestal 16, so that the mesh box lower pedestal 16 makes a horizontal vibration (H direction) do. This causes the mesh box 30 for constituting a plurality of layers to be layered between the mesh box lower pedestal 16 and the mesh box upper pedestal 20 to horizontally vibrate in a plane.

A vertical vibration motor 44 is fixedly disposed at the center of the upper surface of the mesh box upper pedestal 20. An up-and-down oscillation eccentric rotation body 46 is eccentrically coupled to the rotary shaft of the up-and-down vibration motor 44. At this time, the rotary shaft of the vertical vibration motor 44 is installed horizontally.

Upper and lower vibration springs 52 and 54 are installed to be respectively inserted into upper and lower portions of the vibration bar 14 to allow the vertical vibration of the mesh box 30 for constituting the grain to be a certain displacement and to support the mesh box 30 with elastic force .

Therefore, the center of gravity of the up-and-down-vibration eccentric rotation body 46 is repeatedly moved up and down when the up-and-down vibration motor 44 is driven to rotate so that the mesh box lower pedestal 16 is vertically vibrated, A plurality of mesh boxes 30 for layering the grain constituting between the mesh box upper pedestal 16 and the mesh box upper pedestal 20 are vertically horizontally vibrated.

As described above, according to the present invention, when the horizontal vibration motor 40 and the vertical vibration motor 44 are driven to rotate at the same time, a plurality of layered layered mesh boxes 30 are vibrated horizontally and vertically . As a result, the pulverized raw material fed into the mesh box 30 for constituting the uppermost grain is sifted downward sequentially in the mesh box 30 for constituting a grain, and sorting is performed.

Here, when the horizontal vibration motor 40 is rotated and driven, the eccentric rotation body 42 rotates away from the center of the rotation axis of the mesh box lower pedestal 16, so that the mesh box lower pedestal 16 is horizontally vibrated. This causes the mesh box 30 for constituting a plurality of layers to be layered between the mesh box lower pedestal 16 and the mesh box upper pedestal 20 to horizontally vibrate in a plane. At this time, the vibrating rod 14 serves to support the mesh box 30 for constituting a plurality of grains, including the mesh box lower pedestal 16 and the mesh box upper pedestal 20, in the selector frame 12 when vibrating .

When the vertical vibration motor 44 rotates, the center of gravity of the up-and-down vibration eccentric rotation body 46 repeats up and down so that the upper and lower vibration springs 52 and 54 expand and contract. The vertical vibration of the lower pedestal 16 is induced and a plurality of mesh boxes 30 for constituting the grains layered between the mesh box lower pedestal 16 and the mesh pedestal upper pedestal 20 are horizontally vibrated .

The mesh box 30 for constituting the grain comprises a lower netting 32 and an upper netting 34 disposed on the lower side of the lower netting 32 as shown in Fig. The lower mesh body 32 includes a lower mesh reinforcement frame 321 having a rectangular cross section and a rectangular band shape, a split partition plate 322 for dividing the inner area of the lower mesh reinforcement frame 321 into a plurality of areas, And a lower net 333 provided on an inner bottom surface of the lower net 331. The upper net 34 includes an upper mesh reinforcement frame 341 having a rectangular cross section and a rectangular band shape and an upper net 342 provided on the inner bottom surface of the upper mesh reinforcement frame 341.

Therefore, the raw material of the grain is sieved in the upper net 342 of the upper netting 34 from the mesh box 30 for constituting the grain, and then the secondary netting is secondarily formed in the lower net 333 of the lower enclosure 32.

Preferably, the lower net member 32 is provided with a plurality of vibration balls 36 positioned in respective divided regions divided by the partitioning partition 322 and performing free rolling and vertical vibration motion in the corresponding regions. For example, two or three vibration balls 36 may be installed in one divided area. The vibration ball 36 may be made of rigid metal material or metal or hard plastic that does not break well into a spherical shape.

Therefore, when the vibrating ball 36 is installed, the vibrating ball 36 vibrates together with the vibrating ball 36 vertically (in the V direction) by the vertical vibration of the mesh box 30 for constituting the grain as shown in Figs. 5A and 5B, It is possible to increase the constitutional effect by eliminating clogging of the mesh eye by repeatedly hitting it.

In another embodiment, as shown in FIG. 6, a vibration brush 38 may be installed in each of the divided regions divided by the partitioning plate 322 in the lower net 32 to perform a horizontal movement and a vertical vibration have. The vibration brush 38 is provided with a brush body 381 having a cross shape as shown in FIG. 7A and a brush 382 protruding upward from the upper surface of the brush body 381. Or the brush body 381 may be configured in a Y-shape other than the illustrated form. The vibrating brush 38 may further include a tilting projection 383 so that the vibration brush 38 is inclined on the lower surface of the brush body 381 as shown in FIG. 7B. The tilting protrusion 383 is located at a position deviated from the center of gravity of the brush body 381.
