Compressive plate drives structure of the present invention, top cover by the middle part of upper cover top, upper cover bottom and upper cover three layers form, be support portion in the middle part of upper cover, arrange driving gear and driven gear in the middle part of upper cover, upper cover top is arranged on outside the upper surface in the middle part of upper cover; Upper cover bottom is arranged on the outside of upper cover middle lower surface; Supplemental support and position-limiting action are mainly played in upper cover bottom, and spacing preiection is subject to upper cover lower constraint, make active sliding block to depart from upper cover; Upper cover top is ornamental portion, is enclosed in by rotatable parts wherein, mainly plays effect attractive in appearance.
Dust catcher compressive plate drives structure of the prior art, the drive unit of axle side compression plate is arranged on dust-collecting cylinder and covers, the prerequisite that axle side compression plate rotates is when closing control of dust cover, the driving slide block pointed cone of drive unit must first normally enter in the groove of the pivot tube of axle side compression plate side, and pointed cone and groove proper engagement, intensity and transmission power in order to improve groove in groove are more effectively provided with projection; And due to pointed cone limited length, due to when original design, the connected mode of the groove of the driving slide block pointed cone of drive unit and the pivot tube of axle side compression plate side is for being rigidly connected; Therefore, when closing control of dust cover, easily cause and drive slide block pointed cone normally to enter in groove, in order to driving slide block pointed cone is normally entered groove, need repeatedly to close, it is very inconvenient therefore to use.
And the invention solves this technical barrier, by existing be rigidly connected to change into flexibly connect; Operator is when closing dust collector upper cover, slide block pointed cone is not needed to enter groove, like this when closing dust collector upper cover, only need to close conveniently, once-through operation, there will not be upper cover cannot close this phenomenon, it is more convenient that operator uses, and also prevent the damage that closedown associated components is artificially unnecessary by force.
The operator of dust catcher is after the dust cleared up in dust-collecting cylinder and rubbish, and operating procedure is as follows:
First, close the upper cover of dust-collecting cylinder, the groove being arranged on the pivot tube of the driven sliding block pointed cone aligning compressive plate side of the driven sliding block bottom in upper cover inserts downwards, skid to prevent when transmitting power, improve the validity transmitting power, the gap of groove and driven sliding block pointed cone proper engagement is very little, and therefore under normal circumstances, pointed cone cannot enter groove and form transmission cooperation; But because the driven sliding block being arranged on dust-collecting cylinder upper cover is vertically disposed with activity space in the pilot hole of dust-collecting cylinder, even if driven sliding block end cannot enter groove by pointed cone like this, driven sliding block is by upwards jack-up, and driven sliding block pointed cone can move up vertically and not affect the normal closedown of control of dust cover.
Secondly, close dust collector upper cover, the driven sliding block groove of active sliding block pointed cone to driven sliding block top being arranged on the active sliding block bottom in dust collector upper cover driven gear inserts downwards, equally, in order to when transmitting power, prevent from skidding, improve the validity transmitting power, the gap of driven sliding block groove and active sliding block pointed cone proper engagement is very little, and therefore under normal circumstances, active sliding block pointed cone cannot enter driven sliding block groove and form transmission cooperation; But because the active sliding block be arranged in the hollow shaft of dust collector upper cover location is vertically disposed with activity space in the hollow shaft of location, even if active sliding block end pointed cone cannot enter groove like this, active sliding block is by upwards jack-up, active sliding block pointed cone can move up vertically, the spring be arranged in the hollow shaft of location produces compression, thus ensures that dust collector upper cover can normally be closed.
When the motor being arranged on dust collector upper cover drives driving gear to rotate, power transmission is rotated to driven gear by driving gear, the active sliding block be arranged in driven gear hollow shaft is rotated with driven gear, when active sliding block turns an angle, the pointed cone of active sliding block and driven sliding block groove are to timing, active sliding block, under the effect of the axial force of spring, moves down vertically, and the pointed cone of active sliding block is formed with driven sliding block groove and coordinates; Active sliding block drives driven sliding block to rotate together.
When driven sliding block turns an angle, the pointed cone of driven sliding block and the pivot tube groove of compressive plate side are to timing, driven sliding block, under the effect of the axial force of active sliding block spring, moves down vertically, and the pointed cone of driven sliding block is formed with the pivot tube groove of compressive plate side and coordinates; Driven sliding block drives compressive plate to rotate, and compressive plate carries out squeeze operation to dust in dust-collecting cylinder.
Compressive plate drives structure of the present invention, the actuating unit driving compressive plate to rotate is made up of Elastic Sliding device, flexibly connecting of being made up of spring, active sliding block and driven sliding block is changed into by being rigidly connected, control of dust cover and dust collector upper cover can once be closed, simple operation, power transmission is reliable.
