It comprises a coupling pipe 32b. Holes 34c penetrating the upper support rod 34 are formed at both edges of the upper support rod 34, and bolts 33 are fitted into the holes 34c. The bolt 33 is inserted into the coupling pipe 32b through the hole 34c, and the nut 35 is fastened to the bolt 33 protruding toward the rear of the coupling pipe 32b, so that the upper support rod 34 and Fix the connecting member 32 integrally.

As described above, the vibrator 31 is coupled to the upper support bar 34 through the connecting member 32, and the vibrator 31 is installed in the rotatable structure with respect to the connecting member 32. It can be in close contact and rotate freely.

On the other hand, the upper support bar 34 includes a plurality of connecting projections 34a arranged along the longitudinal direction, the connecting projections 34a are formed in a threaded structure to fit the screen bar 36 do. In addition, the lower support bar 38 also includes a plurality of connecting protrusions 38a arranged in the longitudinal direction, and the connecting protrusions 38a are also formed in a threaded structure to fit the screen bar 36. . The screen rod 36 has a fastening end 36a with an inner circumferential surface threaded at both ends thereof so as to be engaged with the connecting protrusions 34a and 38a.

Therefore, the fastening end 36a of the screen rod 36 and the connecting protrusions 34a and 38a may be coupled to stably support the screen rod 36 on both sides, and the screen rod 36 and the supporting rods 34 ) 38 can be easily assembled and easily installed.

As shown in FIGS. 1 and 2, the screen portion 30 is installed between the upper support rod 34 and the bottom to support the upper support rod 60 and the lower support rod 38 and the bottom that support the upper support rod 34. It is further provided with a lower support 70 is installed in the support for the lower support (38). The upper support 60 is between the upper connector 61 screwed with the support protrusion 34b formed on the upper support rod 34 and the lower connector 63 installed at the bottom, and the upper connector 61 and the lower connector 63. It includes an elastic member 65 installed in.

On the other hand, the lower support 70 is also connected to the support protrusion 38b formed on the lower support rod 38, the upper connector 71 and the lower connector 73 and the upper connector 71 and the lower connector 73 is installed on the bottom 73 It includes an elastic member 75 is installed between).

Referring to Figure 4 in more detail the configuration of the lower support 70 as follows. Since the upper support 60 and the lower support 70 is made of the same structure, the description of the upper support 60 will be replaced with the description of the lower support 70 below.

The upper connector 71 is protruded to the upper portion of the disk-shaped support plate 71a and the support plate 71a for supporting the elastic member 75 is screwed with the support protrusion 38b formed on the lower support bar 38 A coupling tube 71b and a guide tube 71c formed below the support plate 71a and fitted to the elastic member 75.

On the other hand, the lower connector 73 includes a bottom plate (73a) that is supported on the bottom, and the bottom projection (73b) is formed to protrude to the upper portion of the bottom plate (73a) fitted to the elastic member (75). The bottom protrusion 73b is preferably inserted into the guide tube 71c to move along the guide tube 71c, whereby the upper connector 71 is moved up and down by the elastic member 75 at the correct position. You can exercise.

The elastic member according to the present embodiment is made of a compression spring vibrating by an external force. However, the present invention is not limited thereto, and the elastic member may be formed of various types of elastic bodies such as silicone and rubber.

That is, the vibration unit 31 connected to the upper support rod 34 transmits a constant vibration to the screen unit 30 while being in close contact with the pulley 23, and when the vibration is transmitted to the screen unit 30, the supporter ( The screen unit 30 is moved up and down by the elastic force of the 60 (70).

When the screen unit 30 vibrates up and down, the raw coal transported to the screen unit 30 can pass through the screen unit 30 more easily while moving by vibration, and gangue, etc., which have not passed through the screen unit 30. The foreign matter 14 is gradually moved down by the vibration is discharged to the outside.

As shown in FIG. 1 and FIG. 2, the scattering prevention part 50 is installed on the screen part 30, and the scattering prevention part 50 is installed adjacent to the lower supporting rod so that the raw coal 12 is moved outward. It prevents leakage.

The scattering prevention unit 50 includes a support 58, a rod 52 rotatably installed on the support 58, and a blocking plate 54 fixed to the rod 52. The blocking plate 54 is fixed to the rod 52 to be installed to extend to the screen portion 30 and is preferably made of a flexible material such as rubber.

As such, the scattering prevention unit 50 may be installed to prevent the raw coal 12 from leaking to the outside, and the rod 52 may be rotatably installed so that foreign matters 14 such as gangue are blocked by the blocking plate 54. If the transfer is carried out to press only the cut off, the rod 52 can be rotated to easily discharge the foreign matter 14 such as gangue.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications and changes can be made within the scope of the claims and the detailed description of the invention and the accompanying drawings. Naturally, it belongs to the range of.

As described above, according to the present invention, a screen portion is installed between the upper transfer portion and the lower transfer portion to easily remove foreign substances from the raw coal.

In addition, the vibrating unit is fixed to the screen unit, so that the raw material coal can easily exit the screen unit by vibrating the screen unit, foreign matters can be easily discharged to the outside blocked by the screen unit.

In addition, the elastic member is installed on the support of the screen portion, the screen portion can be more easily vibrated.

In addition, the scattering prevention portion is installed on the upper portion of the screen portion can be stably prevented the leakage of the raw coal.
