moreover, in order to make the stirring driven gear 41 have a space for moving, a movable groove 61a for horizontally moving the stirring shaft 42 towards the center of the turntable 61 is arranged on the turntable 61, a sliding seat 67 is arranged in the movable groove 61a in a sliding way through a sliding rail, the stirring shaft 42 is fixedly arranged in the sliding seat 67 to enable the stirring shaft 42 to move on the movable groove 61a after the transmission gear 64 rotates along with the rotating frame 63, in order to shift the transmission gear 64 and further drive the stirring driven gear 41 to move, a linkage arm 65 is arranged between the transmission gear 64 and the stirring driven gear 41 to enable the transmission gear 64 and the stirring driven gear 41 to be meshed, a worm gear tooth surface is arranged on the rotating frame 63, a shifting motor 66 is arranged in the turntable 61 to drive the rotating frame 63 to rotate on the basis of position self-locking through a worm, so that after the rotating frame 63 drives the transmission gear 64 to swing and shift along with the reference gear 5, the stirring driven gear 41 moves in the movable groove 61a straight line through the swinging of the linkage arm 65 along with the transmission gear 64, and the distance between the two stirring frames 4 is shortened, and the stirring diameter area of the two middle stirring frames 4 is greatly enlarged.
After the stirring frame 4 approaches, the stirring frame 4 has a space for vertically moving on the stirring shaft 42, the bottom end of the turntable 61 is provided with a guide frame 7 for guiding the horizontally moving stirring frame 4 downwards so that the bottom end of the stirring frame 4 enters the range of the center of the curved part 1b, specifically, the stirring shaft 42 is in two nested shapes so that the stirring frame 4 at the bottom end has the freedom degree of moving up and down, the stirring shaft 42 connected with the stirring frame 4 is provided with a positioning disc wheel 46 which abuts against the guide frame 7 so that the up-down movement of the stirring frame 4 is guided by the guide frame 7, the positioning disc wheel 46 comprises a disc base 461 fixed on the stirring shaft 42, a plurality of guide wheels 462 which are arranged at the bottom end of the disc base 461 in an eccentric array through an eccentric shaft 463, the guide frame 7 is provided with two at one stirring shaft 42 and is respectively arranged at two sides of the stirring shaft 42, and the disc base 461 rotates on the guide wheels 462 so as to drive the stirring frame 4 to be supported on the guide frame 7, so that the stirring frame 4 approaching each other can also contact the range of the center part 1b downwards on the basis of the expanded stirring flow which crosses the middle part, thereby increasing the stirring effect;
it is known that the guiding frame 7 may have two horizontal sections, the two horizontal sections are connected by a section of inclined section, when the rotating frame 63 drives the driving gear 64 to pull the stirring driven gear 41 to move horizontally to a proper position, the positioning disc wheel 46 is moved from the high horizontal section to the low horizontal section, and then the stirring frame 4 is stably lowered to the central area of the curved portion 1b for stable stirring, the plurality of guiding wheels 462 arranged around the positioning disc wheel 46 can ensure that the stirring frame 4 can move while rotating, in implementation, the inner side and outer side of the guiding wheels 462 are provided with elastic reset rings 464 which are abutted against the guiding wheels 462, when the positioning disc wheel 46 moves obliquely on the guiding frame 7, the guiding wheels 462 tilt through the eccentric shafts 463, and the reset rings 464 provide elastic force for resetting the guiding wheels 462, so that the guiding wheels 462 can perform certain offset to adapt to the inclined section when climbing or descending on the inclined section.
In order to prevent the situation that after the positions of meshing points of the stirring driven gears 41 and the transmission gears 64 change, the two stirring frames 4 have interference dead points, namely, after the transmission gears 64 rotate, the stirring driven gears 41 only move in one straight line direction, which is equivalent to the situation that the stirring driven gears 41 climb on the transmission gears 64 for a certain distance, so that the meshing points of the stirring driven gears 41 and the transmission gears 64 change, the meshing point change can lead the stirring driven gears 41 to drive the stirring shafts 42 to twist at a certain angle, so that the twisting of the two stirring frames 4 in the same direction can lead to the shortening of the minimum distance between the two stirring frames 4, and therefore, after the two stirring frames 4 are pulled close, the situation that the independent rotation of the two stirring frames 4 can interfere with each other exists can be caused, because the stirring range and the overlapping range of stirring areas of the stirring frames 4 are considered, on the basis, the stirring driven gears 41 and the stirring shafts 42 are in nested connection, the relative rotation between the stirring driven gears 41 and the stirring shafts 42 enables the included angles between the stirring frames 4 on the two stirring shafts 42 to be 87 DEG-93 deg;
