Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 to 4, the utility model comprises a barrel body 1 with an upward opening, wherein a plurality of vertical support rods 2 are arranged on the right side of the barrel body 1, a first support plate 3 and a second support plate 4 which are arranged in parallel up and down are arranged on the support rods 2, a rotating shaft 5 is arranged in the middle of the first support plate 3, a plurality of vertical side rods 6 are evenly distributed on the upper circumference of the first support plate 3, and the lower ends of the side rods 6 are arranged in the barrel body 1; the rotation of the rotating shaft 5 can drive a plurality of side rods 6 to rotate simultaneously; a blind hole with a square cross section is formed in the rotating shaft 5, an intermediate rod 7 is inserted in the blind hole, a square block 8 is arranged at the upper end of the intermediate rod 7, and the square block 8 can move up and down along the blind hole; the middle part of the middle rod 7 is provided with a bidirectional screw thread 9; a nut 10 matched with the thread 9 is fixed on the second support plate 4; the middle rod 7 and the side rod 6 are arranged in the barrel body 1, and the stirring blades 11 are arranged on the parts.

In order to realize the rotation of the rotating shaft 5, the upper end of the supporting rod 2 is provided with a supporting arm 12, the left end of the supporting arm 12 is fixed with a motor 13, and the right end is fixed with a balancing weight 14; the output shaft of the motor 13 is linked with the upper end of the rotating shaft 5 through a coupler.

In order to realize the simultaneous rotation of the rotating shaft 5 and the side rods 6, a large gear 15 is arranged in the center of the rotating shaft 5, and a small gear 16 meshed with the large gear 15 is arranged on each side rod 6.

For more stability, a sleeve 17 is installed at the center of the bottom of the barrel body 1, and the lower end of the middle rod 7 is arranged in the sleeve 17 and can move up and down along the sleeve 17.
