DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0023] according to Figure 1-8 As shown, a stirring shaft structure of a high-power mixer comprises a shaft body 1, on which a plurality of groups of connecting sleeves 2 are movably mounted, the connecting sleeves 2 are arranged in an array on the shaft body 1, two groups of mounting holes 21 are provided on the inner side wall of the connecting sleeve 2, the two groups of mounting holes 21 are symmetrically arranged on the connecting sleeve 2, a blade seat 3 is movably mounted in the mounting hole 21, a plurality of groups of limiting protrusions 31 are provided on the circumferential side wall of the blade seat 3, a limiting groove 22 matching the limiting protrusion 31 is provided in the mounting hole 21, a boss 32 is provided at one end of the blade seat 3 close to the shaft body 1, a groove 11 matching the boss 32 is provided on the side wall of the shaft body 1, a blade 8 is fixedly mounted on one end of the blade seat 3 away from the shaft body 1 by bolts, and a fixing plate 6 is detachably mounted on the bottom end of the shaft body 1.

[0024] In this embodiment, a first slide groove 12 and a second slide groove 13 are provided on the side wall of the shaft body 1, and the first slide groove 12 and the second slide groove 13 are both T-shaped grooves. The first slide groove 12 and the second slide groove 13 are distributed perpendicular to each other on the shaft body 1, and a slider 23 is provided on the inner side wall of the connecting sleeve 2. The connecting sleeve 2 is sequentially installed on the shaft body 1 through the slider 23, and the connecting sleeve 2 is staggered from top to bottom in the first slide groove 12 and the second slide groove 13, so that the blades 8 on each group of connecting sleeves 2 are staggered at 90 degrees.

[0025] In this embodiment, a guide groove 14 is laterally arranged on the side of the first slide groove 12 and the second slide groove 13. The position of the guide groove 14 corresponds to the slider 23. The slider 23 can slide into the guide groove 14, so that the connecting sleeve 2 can rotate 45 degrees on the shaft body 1, so that the boss 32 can be aligned with the groove 11. When the boss 32 is pushed into the groove 11, the limiting protrusion 31 on the blade seat 3 disengages from the limiting groove 22, so that the blade seat 3 can be rotated.

[0026] In this embodiment, the boss 32 is a cylindrical structure, and a spring 4 is sleeved on the boss 32. The end of the mounting hole 21 away from the limiting protrusion 31 is fixed with a cover plate 5 by bolts, and a through hole 51 corresponding to the boss 32 is opened on the cover plate 5. When it is necessary to adjust the angle of the blade 8, the operator pushes the blade seat 3 inward so that the boss 32 passes through the through hole 51 and enters the groove 11. After the angle of the blade 8 is adjusted, the operator releases the blade seat 3, and the blade seat 3 is pushed outward under the action of the spring 4, so that the limiting protrusion 31 is re-engaged in the limiting groove 22.

[0027] In this embodiment, a plurality of positioning holes 15 are provided at the bottom of the shaft body 1, and positioning columns 61 corresponding to the positioning holes 15 are welded on the fixing plate 6. The fixing plate 6 is inserted into the shaft body 1 through the positioning columns 61. A threaded hole 16 is provided at the bottom axis of the shaft body 1, and a fastening bolt 7 is installed on the fixing plate 6. The fixing plate 6 is fixedly installed at the bottom of the shaft body 1 through the fastening bolt 7, and the connecting sleeve 2 is pressed and fixed on the shaft body 1 through the fixing plate 6.

[0028] When the utility model is in use, first slide the slider 23 of the first group of connecting sleeves 2 into the first slide groove 12, then slide the slider 23 of the second group of connecting sleeves 2 into the second slide groove 13, and then install the subsequent connecting sleeves 2 on the shaft body 1 in a staggered manner, and finally align the positioning column 61 of the fixing plate 6 with the positioning hole 15, and firmly install the fixing plate 6 by the fastening bolt 7, and at the same time, each group of connecting sleeves 2 is pressed and fixed by the fixing plate 6. When it is necessary to adjust the blade angle, the operator loosens the fastening bolt 7 by a wrench. At this time, a gap is generated between the connecting sleeves 2, so that the connecting sleeves 2 can be rotated along the corresponding guide groove 14. When the slider 23 moves to the extreme position of the guide groove 14, the boss 32 of the blade seat 3 is aligned with the groove 11. At this time, the operator can push the blade seat 3 inwardly to disengage the limiting protrusion 31 from the limiting groove 22, thereby being able to rotate the blade seat 3. After adjusting to a suitable angle, the blade seat 3 is released, and the blade seat 3 is pushed outward under the action of the spring 4, so that the limiting protrusion 31 is re-engaged in the limiting groove 22 to limit the blade seat 3. After repeating the above steps to adjust the blades 8 on the other side, the connecting sleeve 2 is rotated in the opposite direction to reset it, and the boss 32 abuts against the side wall of the shaft body 1 to radially position the blade seat 3. After the angle adjustment of all the blades 8 is completed, the operator retightens the fastening bolts 7, and the connecting sleeve 2 is pressed and fixed by the fixing plate 6 to complete the angle adjustment of the blade 8 to meet the experimental requirements.
