Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. It should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "setting" should be understood in a broad sense. For those of ordinary skill in the art, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0021] Refer to Figures 1-3 , a stirring device for silt solid waste raw materials, including a cylinder body 1. A support plate 8 is fixed at the top position of the cylinder body 1 by bolts. A sliding seat 15 is slidably connected through the middle position of the support plate 8. A stirring assembly is provided at the bottom of the sliding seat 15. A lifting assembly for controlling the up and down movement of the sliding seat 15 is provided on the inner wall of the bottom of the cylinder body 1, so that the stirring assembly can move up and down during the stirring process to stir the solid waste at different liquid levels in the cylinder body 1. Rotating shafts 6 are rotatably connected to the outer walls on both sides of the cylinder body 1. Rotating plates 4 are fixed on both rotating shafts 6 by bolts. The rotating plates 4 are arranged obliquely. A hitting ball 3 is fixed at the bottom of the rotating plate 4 by bolts. An extrusion assembly for controlling the swinging of the rotating plate 4 is provided on the sliding seat 15, so that the hitting ball 3 rotates to knock on the outer wall of the cylinder body 1.

[0022] In the present invention, the stirring assembly is a plurality of stirring bars 12. A motor 14 is fixed at the bottom of the sliding seat 15 by bolts. One end of the output shaft of the motor 14 is key-connected to a transmission shaft 10. A connecting disc 13 is fixed on the circumferential outer wall of the transmission shaft 10 by bolts. A plurality of stirring bars 12 are respectively fixed on the outer walls of multiple sides of the connecting disc 13. The rotation of the motor 14 causes the transmission shaft 10 to rotate. The rotation of the transmission shaft 10 causes the connecting disc 13 to drive a plurality of stirring bars 12 to rotate to stir the raw materials. The plurality of stirring bars 12 are S-shaped. The S-shaped stirring bars 12 can increase the stirring range.

[0023] In the present utility model, the lifting assembly includes a connecting rod 11 and an annular frame 16. The connecting rod 11 is fixed to the bottom end of the transmission shaft 10 by bolts, and the annular frame 16 is fixed to the inner bottom wall of the cylinder body 1 by bolts. Moreover, the connecting rod 11 is in contact with the surface of the annular frame 16. The annular frame 16 is inclined as a whole. Both ends of the sliding seat 15 are penetrated and slidably connected with positioning rods 18, and the bottom ends of the positioning rods 18 are fixed to the support plate 8. Spring 17 is sleeved on the circumferential outer walls of the two positioning rods 18, and both ends of the spring 17 are fixed to the positioning rod 18 and the sliding seat 15 respectively. When the transmission shaft 10 rotates, the connecting rod 11 rotates, and the connecting rod 11 moves along the surface of the annular frame 16. Due to the different heights of the annular frame 16, during the rotation of the connecting rod 11, the transmission shaft 10 moves upward as a whole. The sliding seat 15 can move upward along the positioning rod 18, and the spring 17 is stressed and stretched. When the connecting rod 11 rotates and rotates to the bottom end of the annular frame 16, the spring 17 rebounds and resets, and the sliding seat 15 moves downward as a whole. Thus, during the rotation of the stirring bar 12, it can fluctuate up and down to stir the raw materials at different liquid levels, making the stirring more thorough.

[0024] In the present utility model, the extrusion assembly is the top plate 7. Top plates 7 are fixed to both sides of the sliding seat 15 by bolts, and the top plates 7 are in contact with the rotating plate 4. Torsion springs 5 are sleeved on the circumferential outer walls of the two rotating shafts 6, and both ends of the torsion springs 5 are fixed to the rotating shafts 6 and the cylinder body 1 respectively. During the upward movement of the sliding seat 15, the top plate 7 moves upward. The movement of the top plate 7 squeezes the rotating plate 4, and after being squeezed, the rotating plate 4 rotates inward, and the torsion spring 5 generates torsion. When the rotating plate 4 rotates inward, the hitting ball 3 rotates inward to hit the outer wall of the cylinder body 1, and the cylinder body 1 generates vibration under the hitting, which can shake off the raw materials adhering to the inner wall of the cylinder body 1 in time. When the top plate 7 moves downward, the torsion spring 5 can slowly reset to make the rotating plate 4 rotate outward, and the hitting ball 3 disengages from the outer wall of the cylinder body 1.

[0025] In the present utility model, a discharge opening is formed at the bottom of the cylinder body 1, and a bottom cover 9 is rotatably connected in the discharge opening. Rotating the bottom cover 9 can open the discharge opening, and the stirred raw materials can be discharged through the discharge opening.

[0026] In the present utility model, a plurality of support legs 2 are fixed to the outer bottom wall of the cylinder body 1 by bolts.

[0027] Working principle: When it is necessary to stir the solid waste raw materials, pour the raw materials into the cylinder body 1, start the motor 14, the rotation of the motor 14 causes the transmission shaft 10 to rotate, the rotation of the transmission shaft 10 causes the connecting disk 13 to drive a plurality of stirring bars 12 to rotate to stir the raw materials, and the rotation of the transmission shaft 10 causes the connecting rod 11 to rotate. The connecting rod 11 moves along the surface of the annular frame 16. Since the height of the annular frame 16 is different, during the rotation of the connecting rod 11, the transmission shaft 10 moves upward as a whole. The sliding seat 15 can move upward along the positioning rod 18, and the spring 17 is stressed and telescoped. When the connecting rod 11 rotates and rotates to the bottom end of the annular frame 16, the spring 17 rebounds and resets, and the sliding seat 15 moves downward as a whole. Therefore, during the rotation of the stirring bar 12, it can fluctuate up and down to stir the raw materials at different liquid levels, making the stirring more thorough;

[0028] During the upward movement of the sliding seat 15, the top plate 7 moves upward. The movement of the top plate 7 squeezes the rotating plate 4. After being squeezed, the rotating plate 4 rotates inward, and the torsion spring 5 generates torsion. The inward rotation of the rotating plate 4 causes the hitting ball 3 to rotate inward to hit the outer wall of the cylinder body 1. The cylinder body 1 generates vibration when hit, and the raw materials adhered to the inner wall of the cylinder body 1 can be shaken off in time. When the top plate 7 moves downward, the torsion spring 5 can slowly reset to make the rotating plate 4 rotate outward, and the hitting ball 3 is separated from the outer wall of the cylinder body 1.

[0029] In this application, the structures and connection relationships not described in detail are all prior arts, and their structures and principles are well-known technologies, so they will not be elaborated here.

[0030] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
