Technical effect: limiting the glide direction of gag lever post by guide cylinder, to limit the direction of vibration of vibration rod, reduces
The swing of vibration rod.
The technical solution that the utility model further limits is: the mounting hole passed through for spring, spring are provided on sieve compartment
One end is equipped with the end cap of closing mounting hole.
The utility model is further arranged to, and the oil filler point of connection guiding tube inner chamber is provided on end cap, and oil filler point passes through close
Blocking closing.
The utility model is further arranged to, and sealing-plug end is equipped with the pull ring for pulling sealing-plug.
The utility model is further arranged to, and end cap is removably mounted on mounting hole by bolt.
The utility model is further arranged to, and guide cylinder is removably mounted on the inner wall of sieve compartment by bolt.
The utility model is further arranged to, and seal washer is equipped between channel and gag lever post.
The utility model is further arranged to, gag lever post be located between one end of guide cylinder and the inner wall of guide cylinder there are
Gap.
The beneficial effects of the utility model are:
(1) existing sieve compartment is usually to be wholely set, and internal spring influences to be easily damaged due to receiving to swing, because
The maintenance and replacement of this spring are inconvenient, and the spring in this programme protrudes into guide cylinder by mounting hole, and is fixed on by end cap
On sieve compartment, to facilitate the maintenance and replacement of spring；
(2) pass through oil lubrication in the utility model between gag lever post and guide cylinder, reduce the resistance of gag lever post vibration,
To increase the displacement that gag lever post shakes every time, i.e. vibration amplitude, keep the shaking-sieving effect of coal dust more preferable.
