The stirring shaft horizontally arranged in the massecuite distribution groove is long and can reach 40 meters at maximum, in order to facilitate manufacturing and installation, the stirring shaft is generally divided into a plurality of stirring shaft sections, each stirring shaft section is butted in pairs to form the whole stirring shaft through a middle short shaft, the middle short shaft has a transmission function, on the one hand, a bearing seat is required to be arranged on the periphery of the middle short shaft to rotatably support the stirring shaft, the weight of the whole stirring shaft is supported through a plurality of rotation supporting points, and the stirring shaft is prevented from flexible bending deformation under the gravity.
Syrup is filled in the massecuite distribution groove during operation, the whole stirring shaft is soaked in the syrup, lubricating oil cannot be provided for lubricating the inner bearing part, and therefore dry friction is generated between the middle short shaft and the bearing bush of the bearing seat, abrasion is easy to occur, and the middle short shaft and the bearing bush are required to be disassembled and assembled regularly for overhauling and maintenance. The connection coaxiality is ensured by commonly using flange connection with concave-convex surface matched between the middle short shaft and the stirring shaft section of the existing structure, and if the requirement on coaxiality is not too high, spline connection can be adopted, no matter the flange connection with concave-convex surface or the spline connection is adopted, when the middle short shaft of a certain section is to be disassembled for overhauling and maintenance, the stirring shafts on two sides of the middle short shaft of the section are required to be axially moved, so that the flange connection with concave-convex surface or the spline connection are thoroughly separated, and the middle short shaft of the section can be disassembled. But the work of axially moving the two sides of the axial direction of the stirring shaft on the two sides of the middle short shaft is very troublesome in the actual operation process, and especially for the current novel full-sealed O-shaped massecuite distribution groove, the whole disassembly and assembly process is time-consuming and labor-consuming and is excessively complicated because a plurality of parts such as a driving gear motor and a bearing seat of the head part are required to be disassembled.
Disclosure of Invention

Furthermore, the cylindrical shaft body of the mandrel is connected with the shaft sleeve in an interference fit manner. Preferably, the shaft sleeve is made of wear-resistant alloy materials.
Further, when the middle short shaft is connected with the stirring shaft sections at the left end and the right end, the plane flange of the middle short shaft is in plane butt joint with the butt flange of the stirring shaft section, and the connecting coaxiality is ensured by locking through nuts after the bolt with the reaming holes passes through the mounting holes of the plane flange and the corresponding mounting holes of the butt flange.
The advantage of the intermediate minor axis of the massecuite distributing groove (mixing) shaft of this novel structure is: the middle short shaft is sleeved with the shaft sleeve outside the cylindrical shaft body of the mandrel, and only the shaft sleeve is worn during wear, so that the shaft sleeve is only required to be replaced each time, and the method is simple and economical; the two ends of the mandrel of the middle short shaft are connected with the plane flange through the square shaft heads, so that the transmitted moment is large, and the worn shaft sleeve is easy to detach and replace; the outer side end surface of the plane flange of the middle short shaft is provided with the counter bore to install the locking pressing disc, so that the locking component does not exceed the outer side end surface of the plane flange, interference caused when the middle short shaft is taken out is avoided, and the middle short shaft can be pulled out without axially moving stirring shafts on two sides of the middle short shaft; the plane flange of the middle short shaft is connected with the butt flange of the stirring shaft section by adopting a reaming hole bolt, so that the connection coaxiality can be ensured, and the transmitted torque is larger. Therefore, compared with the middle short shaft of the existing structure, after the middle short shaft of the novel structure is used, when overhauling and maintaining are carried out, the workload can be greatly reduced, and the working efficiency is improved.
