DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0020] As Figures 1-3The utility model provides a kind of conical mixer, as shown in Figure 5, the utility model provides a kind of conical mixer, including conical bin body 1, the bottom end of bin body 1 is provided with stirring hole, first spherical sliding bearing 2 is equipped in stirring hole, first spherical sliding bearing 2 is fixed with stirring rod 3, one end of stirring rod 3 placed in bin body 1 is fixed with screw rod 4, stirring rod 3 placed in one end of bin body 1 is connected with driving motor 5, the lateral wall of stirring rod 3 is connected with conical driving disc 6, driving disc 6 makes stirring rod 3 do conical swing movement with first spherical sliding bearing 2 as center.
[0021] In use, the material to be stirred is added to bin body 1, driving motor 5 drives screw rod 4 to rotate through stirring rod 3, screw rod 4 drives the local material in bin body 1 to move to the large end of bin body 1, and the remaining material will move to the small end of bin body 1 under the influence of gravity, so that the unevenly mixed material is always close to driving motor 5, and then driving motor 5 can be efficiently used to drive stirring rod 3 and screw rod 4 to stir, thereby reducing energy consumption to a certain extent. While screw rod 4 stirs the material, driving disc 6 drives stirring rod 3 to do conical swing movement with first spherical sliding bearing 2 as center, at this time, stirring rod 3 in bin body 1 will also drive screw rod 4 to do conical swing movement, and rotate along the inner wall of bin body 1, so that screw shaft fully drives the material in bin body 1 to stir, because stirring rod 3 and screw rod 4 can constantly change the contact point with the material and the stirring direction in the process of conical swing movement, it is helpful to break the agglomeration phenomenon between materials, reduce stirring dead angle, so that the material is more fully and uniformly mixed.
[0022] As Figures 1-3The driving disc 6 is conical, and the small end of the driving disc 6 is close to the bin body 1. The bottom end of the stirring rod 3 is connected with a second spherical sliding bearing 7. The outer side wall of the second spherical sliding bearing 7 is provided with a T-shaped sliding block 8. The inclined surface of the driving disc 6 is provided with a T-shaped sliding groove 9. The T-shaped sliding block 8 slides along the T-shaped sliding groove 9. The bottom end of the driving disc 6 is connected with an adjusting motor 10. The bottom end of the adjusting motor 10 is connected with a lifting rod 11. The lifting rod 11 can be an existing hydraulic lifting rod 11. The driving motor 5 can be fixedly connected with the outer side of the second spherical sliding bearing 7 through a connecting sleeve. In the use process, the adjusting motor 10 and the driving disc 6 are lifted by the lifting rod 11. When the driving disc 6 rises, the T-shaped sliding block 8 slides along the T-shaped sliding groove 9. The T-shaped sliding block 8 will be under the support of the driving disc 6, so that the included angle between the stirring rod 3 and the axis of the bin body 1 relatively increases. When the driving disc 6 descends, the included angle between the stirring rod 3 and the axis of the bin body 1 relatively decreases. Through the connection of the T-shaped sliding block 8 and the T-shaped sliding groove 9 and the connection of the second spherical sliding bearing 7 and the stirring rod 3, the rotation angle of the spiral shaft in the bin body 1 can be adjusted, so that the spiral shaft can more fully cover the internal space of the bin body 1, which helps to reduce the dead zone in the stirring process and further improves the mixing uniformity and mixing efficiency of the material. By adjusting the stirring angle, the material flow and mixing mode in the stirring process can be optimized, which is more conducive to the fine mixing of the material.
[0023] As shown in Figures 1-4 The top end of the bin body 1 is provided with an annular groove 12. A supporting rod 13 slides on the annular groove 12.

A long circular hole 16 is arranged on the limiting plate 15. A connecting rod 17 is fixed on the top end of the spiral rod 4. The connecting rod 17 slides in the long circular hole 16. The rotary damper is a prior art. In the use process, the annular groove 12 and the supporting rod 13 provide stable support for the supporting shaft 14 and the limiting plate 15, which ensures the stability and reliability of the whole stirring system in the running process. The long circular hole 16 on the limiting plate 15 accurately limits the connecting rod 17, which ensures that the movement track of the spiral rod 4 in the stirring process is controllable. Not only the stirring accuracy is improved, but also the collision between the spiral rod 4 and the wall of the bin body 1 due to excessive swing is prevented, thereby prolonging the service life of the equipment. The rotary damper can absorb and slow down the impact and vibration in the rotation process, so that the stirring process is more stable and continuous.
[0024] As shown in Figures 2-4As shown, the side wall of the top end of the connecting rod 17 is connected with a third spherical sliding bearing 18, the outer side wall of the third spherical sliding bearing 18 is fixed with a sliding ring 19, the side wall of the long circular hole 16 is provided with a sliding groove 20, the sliding ring 19 moves in the sliding groove 20, and the third spherical sliding bearing 18 is connected with the support shaft 14 through a hydraulic damper 21. The hydraulic damper 21 is prior art. In use, the sliding ring 19 fixed on the outer side of the third spherical sliding bearing 18 cooperates with the sliding groove 20 in the side wall of the long circular hole 16, forming double limiting of the connecting rod 17, which not only improves the accuracy of limiting, but also enhances the stability of the connecting rod 17 in the stirring process, preventing deviation caused by vibration or external force. The third spherical sliding bearing 18 is connected with the support shaft 14 through the hydraulic damper 21, which provides sufficient support for the connecting rod 17 and can withstand the large load generated in the stirring process, thereby prolonging the service life of the equipment, and the hydraulic damper 21 can make the movement of the connecting rod 17 more stable when changing the rotation range, thereby improving the continuity and stability of the stirring process.
[0025] As shown in the drawings, Figures 1-4 The top end of the connecting rod 17 is provided with a cleaning channel 22, the axis of the cleaning channel 22 coincides with the axis of the connecting rod 17, the cleaning channel 22 is communicated with a plurality of drainage openings 23, the drainage openings 23 all penetrate the side wall of the connecting rod 17, the top end of the connecting rod 17 is fixed with a clamping pipe, and the cleaning channel 22 is rotationally connected with a water inlet hose 24 through the clamping pipe. In use, cleaning water is injected into the cleaning channel 22 through the water inlet hose 24 and the clamping pipe, and the cleaning water is discharged through the drainage openings 23, and the driving motor 5 can provide centrifugal force for the cleaning water through the spiral shaft and the connecting rod 17 during cleaning, so that the cleaning water is uniformly sprayed to the inner side wall of the bin body 1 through the drainage openings 23 under the action of the centrifugal force, thereby achieving comprehensive and efficient cleaning of the bin body 1. When the driving motor 5 stops rotating, the cleaning water flows along the blades of the spiral shaft under the influence of gravity, which helps to clean the residues and stains on the spiral shaft.
[0026] As shown in the drawings, Figure 5 The first spherical sliding bearing 2 comprises a ball and a shell, and the ball and the shell are sealingly connected through a sealing ring 25. The sealing ring 25 is prior art.
