the embodiment provides a fertilizer mixer 200 for mixing the raw materials of the compound fertilizer to obtain more uniform ingredients for further granulation. The fertilizer stirring machine 200 comprises a reaction kettle 210, a driving motor 220 and a stirring device 100, wherein the reaction kettle 210 is of a vertical cylindrical structure, the driving motor 220 is arranged above the reaction kettle 210, and the stirring device 100 is vertically arranged in the reaction kettle 210 and is in transmission connection with the driving motor 220 above.

Specifically, the stirring device 100 includes a driving shaft 110 and a stirrer 120, wherein the driving shaft 110 includes a shaft body and a fitting section 112, the shaft body is cylindrical, and the fitting section 112 is in a quadrangular frustum shape. The driving shaft 110 is sleeved with a circular first flange 114, and the first flange 114 is provided with a plurality of bolt holes. In addition, a conical tapered platform 116 is disposed on the drive shaft 110, and the tapered platform 116 is disposed adjacent to the first flange 114 and between the first flange 114 and the mating segment 112. Also, the large end of the tapered land 116 is closer to the first flange 114 than the small end; i.e., the large end of the tapered land 116 is above the small end.

The agitator 120 includes a sleeve 122, an agitating blade 124, and an end connector 126, and the sleeve 122 has a circular cylindrical structure having an inner diameter larger than an outer diameter of the shaft body of the driving shaft 110. Also, the sleeve 122 is provided with a circular second flange 128 at one end and is connected to the end connector barrel 126 at the other end. The end connector barrel 126 includes a mounting bore 1261, the large end of the mounting bore 1261 being disposed proximate the sleeve 122; the mounting hole 1261 has the same shape as the mating segment 112. The end connector barrel 126 is primarily intended for connection with the mating section 112 of the drive shaft 110 and can serve, on the one hand, to limit the free end of the connector barrel in the radial direction thereof and, on the other hand, to transmit torque.

In addition, the flange surface of the second flange 128 is welded and fixed to the end surface of the sleeve 122, and a conical tapered hole is provided in the middle of the second flange 128, and the large end of the tapered hole is provided on the upper end surface of the second flange 128.

The stirring blade 124 is a plate-like structure spirally extending along the outer circumferential surface of the sleeve 122, and is welded and fixed to the sleeve 122. Also, the edge of the agitating blade 124 is provided with a plurality of serrations; in order to improve the wear resistance, the stirring blade 124 is made of wear-resistant steel.

The assembly method and the working principle of the stirrer 120 and the driving shaft 110 are as follows:

when the agitator 120 is assembled with the drive shaft 110, the sleeve 122 is sleeved on the drive shaft 110 until the fitting section 112 of the drive shaft 110 is fitted with the mounting hole 1261 of the end connecting cylinder 126; that is, the outer surface of the mating segment 112 mates with the inner surface of the mounting hole 1261. At this time, the outer circumferential surface of the shaft body is disposed in a gap with the inner wall of the sleeve 122; the clearance between the conical hole and the outer conical surface of the conical platform 116 is arranged, and a rubber pad is arranged in the clearance between the conical hole and the conical platform. And a gap is also left between the first flange 114 and the second flange 128. Finally, the first flange 114 and the second flange 128 are connected and fixed by bolts. Also, the first flange 114 is smaller in diameter than the second flange 128, thereby facilitating removal of the agitator 120 by tapping the second flange 128 after the bolts have been removed.

The design ensures that the matching section 112 can be reliably matched with the mounting hole 1261, and the conical table 116 is reliably matched with the conical hole, so that both ends of the sleeve 122 can be effectively fixed in the circumferential direction, and the additional force applied to the bolt by the swinging of the sleeve 122 when the driving shaft 110 rotates is reduced; the good fit of the mating segment 112 with the mounting hole 1261 also facilitates torque transmission.

In order to further improve the connection reliability of the mating segment 112 to the end connector barrel 126 and to facilitate assembly, in the present embodiment, the outer surface contour of the mating segment 112 in the longitudinal section of the drive shaft 110 is at an angle of 100 ° to the end face of the mating segment 112.

In order to facilitate the machining of the mounting hole 1261, in the present embodiment, the end connecting tube 126 and the sleeve 122 are provided separately, that is, after the end connecting tube 126 is machined, the end connecting tube 126 and the sleeve 122 are welded and fixed.

In order to further fix the stirrer 120 and the driving shaft 110, an end cover 130 is further provided on the end of the connecting cylinder, a through hole is provided in the middle of the end cover 130, and correspondingly, a screw hole is provided on the fitting section 112 of the driving shaft 110; the screw passes through the through hole and then is connected with the screw hole.

Referring to fig. 1, the reaction kettle 210 is a circular cylindrical structure, and a support is disposed below the reaction kettle and is connected and fixed to the foundation through the support below the reaction kettle; an installation rack is arranged above the reaction kettle 210 and used for installing the driving motor 220, the coupler and the like. Two bearing blocks (not shown) are also provided on the mounting bracket for connection to the drive shaft 110 of the stirring device 100. One of the bearing blocks is provided with a ball bearing, and the other bearing block is provided with a thrust ball bearing. When the drive shaft 110 is vertically mounted on the mounting bracket, the thrust ball bearing can be used to withstand axial forces and the roller ball bearing can withstand circumferential forces. Since the reaction vessel 210 may directly adopt a structure of the related art, it will not be described in detail.

It should be noted that in other embodiments, the end connector 126 and the sleeve 122 may be removably connected, such as by a threaded connection; the end cap 130 and the end connector barrel 126 may be integrally formed. Alternatively, the mating segment 112 and the mounting hole 1261 may have a truncated cone shape. Alternatively, the mating segment 112 and the mounting hole 1261 may be cylindrical, in which case the mating segment 112 may be chamfered for ease of assembly.

Example 2:

the present embodiment provides another fertilizer mixer 200, whose basic structure is the same as that of embodiment 1; the difference is that the end cap 130 is connected to the end connector barrel 126, and the center portion of the end cap 130 is not provided with a through hole, but is modified into a blind hole. In addition, a vertical support rod is arranged at the bottom of the reaction kettle 210, the bottom of the support rod is connected with the bottom of the reaction kettle 210, a conical tip is arranged at the upper part of the support rod, and the conical tip is matched with the blind hole.

The fertilizer mixer 200 is mainly suitable for occasions with longer driving shafts 110 and higher rotating speed; at this time, the support rod can restrict the circumferential free end of the driving shaft 110, thereby reducing the amount of deformation when the driving shaft 110 rotates.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
