Further, the top of the motion bar offers slide opening, and slide bar, the slide bar are slidably connected in the slide opening Top be equipped with limit plate.

By using above-mentioned technical proposal, slidably slide bar, so that limit plate is connected to material screen by the gravity of itself On, so as to carry out the limitation of vertical direction to material screen, this case is further improved to the restriction effect of material screen.

Further, the bottom end of the limit plate is equipped with rubber pad two.

By using above-mentioned technical proposal, can avoid limit plate and material screen carry out hard collision, alleviate material screen surface by The abrasion arrived improves the service life of limit plate and material screen.

Further, the bottom of the slide bar is equipped with magnet one, is equipped in the slide opening and the magnetic attracting magnetic of magnet one Iron two.

By using above-mentioned technical proposal, when leaving unused, the magnet one of slide bar bottom be can be adsorbed on magnet two, to limit Slide bar under state is more stable, in addition, magnet two may make magnet one to have to become towards what magnet two moved in the course of work Gesture, so that limit plate can provide material screen bigger pressure, so that it is square vertically to material screen further to promote this case limit plate To restriction effect.

Further, be arranged with spring on the magnet two, the both ends of the spring be connected to slide opening inner wall and On slide bar.

By using above-mentioned technical proposal, spring may make slide bar to have the trend moved towards slide opening bottom, to make Bigger pressure can be provided material screen by obtaining limit plate, further promote this case limit plate to the restriction effect of material screen vertical direction.

In conclusion the utility model has the following beneficial effects:

1, using being set on pedestal there are three sliding bar set, two of them sliding bar set forms material screen entrance, on pedestal It offers limit hole, gag lever post is equipped in limit hole, gag lever post is located at material screen entrance, in use, first by material screen from material screen Entrance is placed on pedestal, and then, gag lever post is placed in limit hole, so that gag lever post is located at vertical state, to limit Bar can carry out the limitation of horizontal direction to material screen, even if can also be limited to vibration sieve box after there is clamping element to loosen, so as to Improve the advantage of experiment success rate；

It 2, include fixed link and motion bar using gag lever post, fixed link is threaded in limit hole, the top of fixed link Portion is rotatablely connected the bottom end of motion bar, and the bottom end of motion bar can be plugged in limit hole, and when installation, motion bar and fixed link are turned Move to concentric and vertical state, fixed link be directed at limit hole, rotation motion bar so that fixed link screw thread effect Lower precession limit hole, from rear, the bottom end of motion bar is plugged in limit hole, so that motion bar can be under the action of limit hole Stable is in a vertical state, closes material screen entrance, to realize the limit for carrying out horizontal direction to vibration sieve box.When movement is completed Afterwards, motion bar can be rotated backward, so that limit hole is produced in the bottom end of motion bar, the screw thread for being kept fixed bar and limit hole connects It connects, i.e. rotatable motion bar, opens material screen entrance, so that material screen can take out from material screen entrance, therefore open and closing Material screen entrance is easy to operate, improves the convenience of operation.
