Detailed Description

The present invention will be described in further detail below by way of specific embodiments:

reference numerals in the drawings of the specification include: the device comprises a case 1, a stop lever 2, an arc-shaped block 3, a driving device 4, a connecting block 5, a stirring rod 6, a swing rod 7, a rotating rod 8, a maintenance cover 9, a limiting hole 10, a connecting cylinder 11, a hemispherical shell 12, a rotating ball 13, a balancing weight 14, a liquid pushing plate 15, a first return spring 16, a second return spring 17, a fixing ring 18 and a sliding ring 19.

Example 1: the small concrete powder mixer in the scheme is shown in figure 1 and comprises a case 1, wherein a driving device 4 consisting of a motor and a gear reducer is fixedly connected to the top of the case 1. The output end of the driving device 4, namely the output shaft of the gear reducer, extends into the case 1 and is rotationally connected with the case 1 through a bearing. The gear-speed-reducing output shaft is fixedly connected with a connecting block 5, and the lower part of the connecting block 5 is provided with a sliding groove.

The bottom of the case 1 is fixedly connected with a maintenance cover 9 through threads, and one side of the maintenance cover 9 close to the inside of the case 1 is fixedly connected with a hemispherical shell 12. As shown in fig. 2 and 3, the maintenance cover 9 is formed with a hemispherical hole, and the rotating ball 13 is placed in the hemispherical hole so that the rotating ball 13 can rotate in the hemispherical hole. The rotary ball 13 is fixedly connected with a connecting cylinder 11, and the connecting cylinder 11 is positioned in the hemispherical shell 12. The outer edge of the top of the connecting cylinder 11 is fixedly connected with an arc-shaped baffle which is connected with the inner wall of the hemispherical shell 12 in a sliding manner. A rotating rod 8 is inserted into the connecting cylinder 11, so that the rotating rod 8 can rotate in the connecting cylinder 11. The top of the hemispherical shell 12 is provided with a limiting hole 10, and a swing gap is formed between the inner wall of the limiting hole 10 and the rotating rod 8. The limiting holes 10 are elliptical holes, the ellipticity is 0-0.45, and the limiting holes 10 are eccentrically arranged. Dwang 8 passes restriction hole 10, and the one end fixedly connected with arc piece 3 of connecting cylinder 11 is kept away from to dwang 8. The arc block 3 is inserted into the sliding groove and can slide in the sliding groove.

A stirring rod 6 is fixed on the rotating rod 8, a tail end pin shaft of the stirring rod 6 is rotatably connected with a swing rod 7, and a stop lever 2 for limiting the swing angle of the swing rod 7 is fixedly connected on the stirring rod 6 so as to avoid collision between the swing rod 7 and the inner wall of the case 1 during swing.

When the device is used, the driving device 4 is started, the connecting block 5 starts to rotate, and the connecting block 5 drives the rotating rod 8 to rotate. When the rotating lever 8 rotates, the restricting hole 10 restricts the swing clearance from the rotating lever 8. The rotating lever 8 starts to swing while rotating by the centrifugal force, but the rotating lever 8 can only swing along the inner wall of the restriction hole 10 due to the restriction of the restriction hole 10. When the machine box swings, solid particles are stirred, the rotating rod 8 sometimes separates from the inner wall of the limiting hole 10 to form irregular stirring, and the stirring is close to the inner wall of the machine box 1 and can act on powder at the edge, so that the stirring is more sufficient. Meanwhile, the limiting hole 10 is an eccentric hole and is matched with the swing rod 7 on the stirring rod 6 and the stop lever 2, so that powder in the corner of the case 1 can be stirred, further stirring is more sufficient, and the collision between the swing rod 7 and the inner wall of the case 1 is avoided.

When in maintenance, the rotating rod 8, the stirring rod 6, the swing rod 7 and the hemispherical shell 12 can be taken out for maintenance or replacement only by taking out the maintenance cover 9 downwards, and the maintenance is simple and easy. When the maintenance cover 9 is taken out, the arc-shaped block is separated from the chute, and the rotating rod 8 is positioned in the connecting cylinder 11 under the action of gravity. After the whole body is taken out, the rotating rod 8 can be directly pulled out from the connecting cylinder 11 for maintenance and replacement.

Example 2: in addition to embodiment 1, as shown in fig. 4, a vertical liquid pushing plate 15 is slidably connected to the side of the casing 1 away from the limiting hole 10. One side of the liquid pushing plate 15 close to the rotating rod 8 is fixedly connected with a fixing ring 18, and a first return spring 16 is rotatably connected to the fixing ring 18. The cover is equipped with sliding ring 19 on the dwang 8, sliding ring 19 and dwang 8 clearance fit, and fixed ring 18 one end fixed connection is kept away from on sliding ring 19 to first reset spring 16. One side of the liquid pushing plate 15, which is far away from the rotating rod 8, is fixedly connected with a second return spring 17, one end of the second return spring 17, which is far away from the liquid pushing plate 15, is fixedly connected to the inner wall of the box body, and the rotating rod 8 is fixedly connected with a balancing weight 14.

The arrangement of the liquid pushing plate 15 avoids the situation that the rotating rod 8 which eccentrically swings can not stir the powder far away from the eccentric side by the stirring rod 6. And the centrifugal force when the rotating rod 8 rotates is used for providing the power for the liquid pushing plate 15, so that the arrangement of other power is avoided.
