Description

Vibrating screen {

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration screen, and more particularly, to a vibration screen for sorting input aggregate by size.

Aggregates are used as raw materials for construction work in rivers, forests, shared waters and other ground or underground rocks (for crushing), sand or gravel.

The aggregate is screened by particle size in an aggregate sorting apparatus equipped with a vibration screen.

Aggregates smaller than the mesh size of the vibration screen pass through the vibration screen and pass downward. Aggregates larger than the mesh size proceed without passing through the vibration screen, and the aggregate is classified according to the mesh size.

However, in the process of wetting the aggregate or crushing the aggregate in the rain, the powder may be hydrated with water and the mesh of the vibration screen of the aggregate sorting apparatus may be clogged or may be discharged together with the aggregate while being attached to the aggregate by surface tension or the like.

In addition, one side of the side surface of the frame 10, which is inclined and positioned on the lower side, is opened so that the aggregate contained in the accommodation space S can be moved in an inclined downward direction and collected.

The vibrating unit can vibrate the frame 10 through an external power source. The vibration by the vibration unit can cause the frame 10 to vibrate up and down.

The filter net portion 30 may be installed in the receiving space S of the frame 10 to filter the inputted aggregate material. Specifically, the filter net portion 30 is a kind of net having a plurality of through holes. Aggregates larger than the through holes are moved downward along the frame 10 inclined from the upper side of the filter net portion 30, Aggregate smaller than the size of the filter net 30 can be separately collected while being accommodated in the receiving space S of the frame 10 while passing through the filter net 30. [

The striking position of the striking part 23 means a position disposed on the upper side of the filter net part 30 while the striking part 23 is located in the accommodation space S of the frame 10. [ When the striking part 23 is located at the striking position, there are many aggregates interposed in the filter net part 30, and the filtering by the filter net part 30 is not smooth.

Since it is possible to move the receiving position of the striking part 23 and the striking position of the striking part 23 when the aggregate interposed in the filter net part 30 does not need to be removed, So that filtering of the aggregate introduced by the filter net portion 30 is not disturbed by the hitting portion 23 and the filter net portion 30 is moved to the receiving position accommodated in the space portion 21, If it is necessary to drop the intervening aggregate, the striking portion 23 is moved from the receiving position to the striking position, so that the aggregate interposed in the filter net portion 30 can be removed.

Further, the striking part 23 can be vibrated through the provided vibration device separately from the vibration part that vibrates the frame 10 in a state of being located at the striking position. In this case, So that only the striking portion 23 is vibrated by a separate vibrating device so that the filter net portion 30 can be priced.

The elastic portion 2333 may be moved in a direction away from the rotary portion 231 of the hammer portion 233b along the longitudinal direction of the rotary portion 231 in accordance with the vibration of the rotary portion 231 The lengths of the extending portions 233a can be varied according to the degree of elastic deformation so that the lengths of the plurality of striking rods 233 can be swung in different states.

The plurality of striking rods 233 may be swung in a state in which the height of each of the striking rods 233 is different from each other in accordance with the vibration of the swinging portion 231. [

The plurality of striking rods 233 are moved in accordance with the up-down movement of the frame 10 and the up-down movement of the swinging part 231 and the external force applied according to the positional relationship with the frame 10 And it is possible to vary the up and down movement period and length variable period of each of the plurality of striking rods 233 to charge the filter net portion 30 with various intensities and periods.

This makes it possible to irregularly strike the aggregate material strongly fixed in the through hole of the filter net part 30 to the outside.

If the plurality of striking rods 233 are pricked with the filter net portion 30 only at a constant force and with a constant period, it may be insufficient to drop the aggregate intervening in the filter net portion 30 in various forms and intensities.
