Through the above technical solutions, since propulsion arm, the blanking pair of related aggregate is arranged in the exit of top layer screening frame
Smaller, another aspect is influenced in the collision of propulsion arm, when aggregate has just fallen in top layer screening frame, aggregate amount is big, and screening is relatively easy to,
Subsequent screening is gradually difficult, and propulsion arm can finally push again aggregate to carry out larger model in the exit setting of top layer screening frame
That encloses stirs, to improve screen rate.
The utility model is further arranged to: the top layer screening frame is equipped with restrained beam, and the restrained beam, which is equipped with, to be supplied
The confinement ring that propulsion arm passes through, the confinement ring are limited for propulsion arm horizontal hunting.
Through the above technical solutions, the confinement ring on restrained beam passes through for propulsion arm, so that propulsion arm is protected, propulsion arm
Opposite oscillating quantity reduce.
The utility model is further arranged to: the side of the top layer screening frame is connected with dust-proof sheet, the dustcloth
It covers the side far from its tie point and is provided with link, top layer sieves frame and is equipped with the extension mounted for link far from the side of dust-proof sheet
Hook.
Through the above technical solutions, dust-proof sheet can cover aggregate after aggregate pours into top layer screening frame, and pass through link
Complete covering is realized in cooperation with hook, to reduce dusty bring plant area pollution.
The utility model is further arranged to: reduction gearbox is equipped between the synchronous motor and synchronizing shaft.
Through the above technical solutions, the setting of reduction gearbox is capable of increasing the torque of synchronous motor, power is promoted.
In conclusion the advantageous effects of the utility model are as follows:
