Detailed description of the invention
The specific embodiment of flat slurry mixer of the present utility model is as shown in Fig. 2-Fig. 8, between the motor shaft 2 of stirring motor 1 and stirring main shaft 7, adopt box coupling 13 coaxial transmissions to connect, one end of this box coupling 13 offers the motor axis hole 130 that inserts of power supply arbor 2, correspondingly on the motor axis hole 130 of motor shaft 2 and box coupling 13 offers keyway and is only screwed and close by the connecting key realization being provided with in keyway.Be provided with the stirring axis hole 131 inserting for stirring main shaft 7 at the other end of box coupling 13, offer in the upper end of stirring in main shaft 7 insertion stirring axis holes 131 dowel hole 70 that radially runs through stirring main shaft 7 central axis, on box coupling 13, being positioned on the sidewall in shaft hole 131 corresponding dowel hole 70 offers and runs through the screwed hole 132 that stirs axis hole 131 inside and outside walls, in this screwed hole 132, be installed with the overload protection pin 14 that stirs main shaft 7 for connecting, this overload protection pin 14 comprise for insert stir the inserting section 142 of dowel hole 70 on main shaft 7 and for the thread segment 141 of box coupling 13 upper screwed hole 132 threaded engagement, the external diameter of the inserting section 142 on this overload protection pin 14 is less than or equal to the path of thread segment 141, so that the installation of this overload protection pin 14, on overload protection pin 14, between inserting section 142 and thread segment 141, be also provided with the groove 143 that a loop diameter is less, the end that is positioned at thread segment 142 on overload protection pin 14 is also provided with is convenient to the bolt head 140 that spanner snaps in, stirring main shaft 7 is only screwed and closes with box coupling 13 by this overload protection pin 14.
When use; be subject to larger resistance and cause equipment to occur when overload when stirring main shaft 7; stirring the active force producing between main shaft 7 and box coupling 13 cuts off overload protection pin 14 from groove 143; make the power of stirring motor 1 pass to and to stir main shaft 7 by box coupling 13; thereby cut off stirring motor 1 and stirred the power transmission between main shaft 7; protect stirring motor 1, stirred the parts such as main shaft 7 and box coupling 13, solved the problem that existing equipment easily damages because of overload.
Further, in the bearing block 5 that stirs main shaft 7, be also separately installed with radial ball bearing 8, thrust ball bearing with flat seat 10 and bearing washer 9 ', radial ball bearing 8 is installed on the bottom of bearing block 5, thrust ball bearing with flat seat 10 is arranged on the top of bearing block 5, bearing washer 9 ' pad is located between radial ball bearing 8 and thrust ball bearing with flat seat 10, stir that upper end outer surface that main shaft 7 exceeds thrust ball bearing with flat seat 10 is also provided with external screw thread 71 and by spinning the clamp nut 12 on this external screw thread 71 by radial ball bearing 8, thrust ball bearing with flat seat 10 and bearing washer 9 ' are pressed abd fixed in bearing block.In addition, for ease of installing, also offer and be parallel to together the draw-in groove 72 that stirs main shaft 7 axis stirring external screw thread 71 places of main shaft 7, and establish one at clamp nut 12 underlays and only screw with this draw-in groove the stop washer closing.Radial ball bearing 8 is arranged on to bearing block 5 bottoms near the lower end of stirring main shaft 7, thereby can increases the aligning ability of radial ball bearing, while avoiding stirring main shaft work, occur the significantly phenomenon of swing.Fix each bearing by clamp nut and can, easily for bearing adds lubricating oil, improve dependability and the service life of bearing.Above also offer some oil-through holes 90 that run through its upper and lower surface around stirring main shaft 7 at bearing washer 9 ', can make the lubricating oil of filling flow to bearing block bottom by oil-through hole 90 and make the radial ball bearing that is positioned at bearing block bottom obtain good lubricating.When avoiding equipment to work under the poor environment of operating mode, the magazines such as dust enter bearing block and reduce bearing service life, and it is also covered with dust cover 15 on bearing block.
