[0030] The stirring shaft is connected and fixed to the rotating sleeve by fasteners, one end of the transmission shaft 1 extends out of the upper end of the rotating sleeve and is connected to the shaft head clamp, and the other end extends toward the stirring shaft but does not contact the stirring shaft;

[0031] The rotating sleeve is also provided with a connecting portion 5, and a pulley is fixedly arranged outside the connecting portion, and the motor drives the rotating sleeve to rotate via the pulley.

[0032] A spherical roller bearing 21 is embedded in the inner side of one end of the rotating sleeve 2 close to the shaft head clamping plate 4, and an elastic retaining ring 211 is embedded on the transmission shaft to limit the spherical roller bearing.

[0033] An annular receiving groove is provided at the end of the rotating sleeve 2 close to the shaft head clamping plate, in which an annular inner frame 23 sleeved outside the transmission shaft is installed. The inner frame is an elastic member and is in line contact with the transmission shaft 1.

[0034] A sealing ring cover plate 11 is provided at one end of the rotating sleeve 2 close to the shaft head clamping plate.

[0035] A tapered roller bearing 22 is provided on the inner side of one end of the rotating sleeve 2 away from the shaft head clamping plate. The tapered roller bearings are a pair and are arranged opposite to each other. Steps matching the tapered roller bearings are provided on the rotating sleeve and the transmission shaft to form a mounting portion for mounting the tapered roller bearings.

[0036] A round nut 24 is provided at one end of the transmission shaft 1 close to the stirring shaft 3 . The round nut is located outside the tapered roller bearing 22 and abuts against the tapered roller bearing.

[0037] The round nuts 24 are two mutually matched ones to lock the tapered roller bearing.
