[0030] The action mechanism includes a support ring 4, which is concentrically suspended below the tank cover 2. A cylinder 5 is concentrically inserted on the inner circumference of the support ring 4. The cylinder 5 can reciprocate axially relative to the support ring 4. The bottom of the rotating shaft 3 is inserted into the top of the cylinder 5. A connecting block 10 is provided at the bottom of the cylinder 5. The bottom of the connecting block 10 is connected to the paddle rod 6. A closed-loop track groove 21 with an eight-shaped structure is axially opened on the inner side wall of the cylinder 5. A track block 22 that slides and engages with the track groove 21 is provided on the outer wall of the rotating shaft 3.

[0031] The top of the support ring 4 is connected to the bottom of the tank cover 2 through a plurality of suspension rods.

[0032] A sliding block 24 is arranged on the inner circumference of the support ring 4 , and a sliding groove 23 cooperating with the sliding block 24 is axially opened on the outer wall of the support ring 4 .

[0033] A second limiting rod 13 is provided centripetally and inclined at the bottom of the support ring 4, and a first limiting rod 12 perpendicular to the paddle rod 6 is slidably inserted on the connecting block 10. One end of the first limiting rod 12 is slidably sleeved on the outside of the second limiting rod 13. The paddle rod 6 is rotatably inserted at the bottom of the connecting block 10, and a roller 15 is provided on the top of the paddle rod 6 to roll and frictionally cooperate with the first limiting rod 12.

[0034] The connection block 10 is provided with a limiting hole 11 which is slidably engaged with the first limiting rod 12 .

[0035] A limiting sleeve 14 is slidably sleeved outside the second limiting rod 13 , and an outer wall of the limiting sleeve 14 is fixedly connected to a corresponding end of the first limiting rod 12 .

[0036] A limiting groove 18 is vertically fixed on the top of the outer wall of the feed pipe 8 near the input end, and a limiting block 17 is slidably provided in the limiting groove 18. The end of the first limiting rod 12 away from the second limiting rod 13 is concentrically inserted on the limiting block 17, and the first limiting rod 12 can move axially relative to the limiting block 17; a pressure rod 19 is provided at the bottom of the outer wall of the limiting block 17, and a valve plate 20 is vertically elastically inserted on the outer wall of the feed pipe 8 near the output end, and the top of the valve plate 20 is pressed into contact with the bottom of the pressure rod 19.

[0037] A pad is installed on the top of the valve plate 20, and a spring is arranged between the bottom of the pad and the outer wall of the feed pipe 8. When the pressure rod 19 does not touch the pad, the valve plate 20 protrudes to the outside of the feed pipe 8. At this time, the feed pipe 8 is in a non-closed state, and the raw material can be put into the material tank 1 through the feed pipe 8.

[0038] A bracket is installed on the outside of the material tank 1.

[0039] The working principle of this embodiment:

[0040] When in use, the phosphogypsum raw material is fed into the material tank 1 through the feed pipe 8, and the motor 9 is started so that its output shaft drives the rotating shaft 3 to rotate, so that the track block 22 on the outer wall of the rotating shaft 3 rubs and squeezes the track groove 21 with an axial closed loop eight-shaped structure, and under the limiting action of the slider 24 and the slide groove 23, the cylinder 5 makes a vertical reciprocating movement on the support ring 4, thereby driving the paddle rod 6 and the paddle blades to synchronously reciprocate vertically through the connecting block 10, thereby expanding the stirring area of ​​the raw materials in the material tank 1.

[0041] When the cylinder 5 moves vertically downward, the connecting block 10 drives the first limiting rod 12 to move downward synchronously through the limiting hole 11, and under the synchronous limiting action of the limiting sleeve 14 and the second limiting rod 13, the first limiting rod 12 moves synchronously toward the inside of the limiting block 17, thereby driving the roller 15, the paddle rod 6 and the paddle blade 7 to rotate. When the cylinder 5 moves vertically upward, the connecting block 10 drives the first limiting rod 12 to move upward synchronously through the limiting hole 11, and under the synchronous limiting action of the limiting sleeve 14 and the second limiting rod 13, the first limiting rod 12 moves synchronously toward the outside of the limiting block 17, thereby driving the roller 15, the paddle rod 6 and the paddle blade 7 to rotate in the opposite direction. As the cylinder 5 moves back and forth up and down, the paddle rod 6 and the paddle blade 7 can be reciprocated to achieve the reciprocating rotation of the paddle rod 6 and the paddle blade 7, thereby fully stirring the raw materials in the material tank 1.

[0042] The limit block 17 moves back and forth in the vertical direction under the driving of the first limit rod 12 and the limiting action of the limit groove 18. When the limit block 17 moves downward, it will contact the pad (spring compression deformation) through the pressure rod 19 to realize the valve plate 20 moving downward into the feed pipe 8, completing the closure of the feed pipe 8. Then, the limit block 17 moves upward to make the bottom of the pressure rod 19 separate from the pad, and the spring elastic force is released, driving the valve plate 20 to move upward and return to the initial position, releasing the closure of the feed pipe 8. In this way, intermittent feeding in the material tank 1 can be realized to avoid excessive feeding, ensure sufficient mixing of raw materials and the quality of the prepared products.

[0043] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
