The inside of the limiting seat 57 is provided with a rod-shaped structure in a vertical state, the central line of the rod-shaped structure coincides with the central line of the limiting seat 57, and the rod-shaped structure and the sliding seat 56 are in a sliding connection state.

Wherein:

e. The limiting seat 57 is fixedly connected with the mounting plate 4, and the central line of the limiting seat is on the same straight line with the middle point of the mounting seat 51; the front surface of the sliding seat 56 is movably hinged with the two connecting rods 55, the hinged point is positioned at the center of the front surface of the sliding seat 56, the sliding seat 56 is mainly made of magnetic materials, and the magnetic pole is S pole; the size of the limit seat 57 is larger than the maximum movement stroke of the slide seat 56. The bottom of the return spring 58 is connected with the bottom of the limiting seat 57, and the top is connected with the sliding seat 56.

f. The electromagnetic devices 59 are provided with five sliding seats 56 respectively corresponding to the five sliding seats, and the positions of the sliding seats 56 and the electromagnetic devices 59 in the same group are on the same straight line; the electromagnetic devices 59 are respectively and electrically connected with the conductor 8 and the coil 9, and the five electromagnetic devices 59 are electrically connected in series; the electromagnetic device 59 does not exhibit a magnetic pole and does not generate magnetism in a non-energized state, and generates magnetism and the magnetic pole is an S-pole in an energized state. The coil 9 is sleeved on the outer side of the driving shaft 6, and the coil 9 is positioned above the front face of the positioning seat 1 and is not in contact with the positioning seat 1 and the driving shaft 6; the coil 9 is concentric with the drive shaft 6. A material conveying plate is arranged between the fixed support rod 52 and the two movable support rods 54, the material conveying plate is of a plate-shaped structure, the middle of the material conveying plate is hinged through a hinge, and the material conveying plate is foldable.

When the material stirring device is used, in an initial state, the driving shaft 6 is connected with an output shaft of the external motor and the motor is started, the output shaft of the motor is connected with an output shaft of the material stirring device, namely the driving shaft 6 is coaxially connected with the output shaft of the stirring device; the discharge port of the storage bin corresponds to a material transfer plate arranged between the fixed support rod 52 and the two movable support rods 54. Because five fixing bases 7 all pass through screw swing joint with mounting panel 4, spacing seat 57 and mounting panel 4 fixed connection to adjustment mechanism 5 is provided with five altogether, the specification is the same and corresponds with five cavitys 3 respectively, so drive shaft 6 can drive mounting panel 4 and adjustment mechanism 5 synchronous syntropy rotation rather than being connected when rotating, and mounting panel 4 can drive positioning seat 1 and the synchronous syntropy rotation of other structures rather than being connected simultaneously.

Because the coil 9 is sleeved on the outer side of the driving shaft 6, the coil 9 is positioned above the front face of the positioning seat 1 and is not contacted with the positioning seat 1 and the driving shaft 6; the coil 9 is concentric with the driving shaft 6, and the conductor 8 is perpendicular to the magnetic induction line of the coil 9, so that when the driving shaft 6 rotates, the conductor 8 is driven to cut the magnetic induction line of the coil 9 and generate an induced current. At normal speed, the induced current generated is not sufficient to make the electromagnetic device 59 generate enough magnetism, so that the sliding seat 56 is at the initial position under the pulling force of the return spring 58, and the two movable seats 53 and the two movable struts 54 are pulled by the two connecting rods 55 to be at the initial position. That is, the two movable struts 54 are close to the mount 51 and the fixed strut 52 at this time, and the distance between the two movable struts 54 and the one fixed strut 52 is small. The spreading angle of the material conveying plate arranged between the fixed support rod 52 and the two movable support rods 54 is small, and the material falling amount is relatively small.

When the rotating speed of the driving shaft 6 is increased, the speed and the frequency of the magnetic induction line of the cutting coil 9 of the conductor 8 are driven to be synchronously increased, the generated induction current value is increased, the magnetic repulsion force generated by the electromagnetic device 59 electrically connected with the induction current value is increased, the pushing force to the sliding seat 56 is increased, and the electromagnetic device 59 pushes the sliding seat 56 to move upwards at the moment by utilizing the principle that like poles repel.

Through the above process, when the sliding seat 56 moves upward, the two connecting rods 55 can be pushed to move upward synchronously, and then the two connecting rods 55 can push the two movable seats 53 and the two movable struts 54 to move away from each other, i.e., move back and forth synchronously, and at this time, the distance between the two movable struts 54 and the one fixed strut 52 increases. The spreading angle of the material transfer plate arranged between the fixed support rod 52 and the two movable support rods 54 is increased, and the corresponding material blanking amount is increased

When the rotational speed of the drive shaft 6 is restored to the normal state, the two movable struts 54 and the one fixed strut 52 are restored to the initial positions in the reverse, away-from-the-same manner as the above-described process.

The above structure and process are shown in FIGS. 1-7.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
