13---main shaft tapered end 14---elasticity card 15---protection joint 16---rotation set lower body
17---upper limit bolt
Come enumeration design feature of the present utility model below in conjunction with drawings and Examples:
In actual design with in making, designer of the present utility model then will be connected on the main shaft by special guiding duplicate invoice by the rotation body that rotation set upper body and rotation set lower body are formed, and be provided with the special protection cover, this protective sleeve not only can stretch vertically but also can rotate with motor and main shaft, also seal the top of axis body simultaneously, to prevent entering of foreign material; The protection joint is then used the lower end of thread connection at the rotation set lower body, for making the downward movement location of rotation body, then is provided with rotation body locating piece on the top of main shaft tapered end, also has been disposed radially the upper limit bolt on the steel ball top of rotation set upper body simultaneously; For the rotary sleeve body can being moved up and down vertically reduce, then on main shaft, offered axially directed groove relative to the rotating of main shaft; In order to improve the service life of steel ball, the designer also locates to have added oil filler point in the steel ball position of rotation set upper body and the radial position of rotation set lower body etc.Like this, when normal use, drive main axis rotation by shaft coupling, and main shaft by the helicla flute on it promote steel ball along the rotation set upper body a descending segment distance, because the special construction of rotation body then no longer moves down after causing steel ball to move a segment distance, and the moment of torsion of main shaft is passed to the rotation body, rotate body and just move down similar helical structure pattern vertically this moment.Again since the downward thrust that the rotation body obtains from axle greater than the clamping force of protection joint elastic card, so the rotation body moves downward with the protection joint, during rotation body locating piece on dropping down onto main shaft, the rotation body no longer moves down, at this moment, the blade that is fixed on the external wall of rotary sleeve also is submerged in the mud just, and at the bottom of jar certain altitude is arranged; With the continuous rotation of motor, main shaft will rotatablely move by steel ball and pass to the rotation body, and drive blade rotation, stirred slurry by the rotation body.And when needs stop agitator work; only need Push switch to make the motor counter-rotating; steel ball in the rotation body of this moment is under the effect of main shaft thrust; a segment distance vertically slightly moves up; when moving on to the upper limit bolt; then no longer mobile; main shaft gives the rotation body thrust that makes progress by steel ball; driven rotary body and protection joint move up together; when moving the rotation set locating piece that contacts main shaft on the protection joint; the thrust that makes progress that is produced by motor continues to move on traction rotation body and the protection joint; make locating piece strut the protection joint and enter assigned address; although motor still rotates, the protection joint touches mutually and moves no longer with main shaft rotation set locating piece, the rotation body; protective sleeve and protection joint and main shaft rotate synchronously.After the outage, the motor stall, because the effect of protection joint makes the blade that is contained on the rotation body no longer because of deadweight drops in the slurry tank, thereby protected agitator to avoid burying in mud, the accident of also having avoided burning motor takes place.
