The stirring rod 5 and the crushing block 6 on the mounting frame 4 perform multi-level stirring and crushing on the feed additives in the mixing tank 2 during rotation. This design achieves a three-dimensional mixing effect, effectively preventing the phenomenon of stratification and caking of additives. The design of the feed pipe 25 and the top cover 26 at the top of the mixing tank 2 facilitates the feeding of raw materials while ensuring the sealing of the stirring process. When different components of the raw materials appear to be caked or agglomerated during the mixing process, the central rod 3 will generate resistance. When the resistance is greater than the preset force of the plurality of pressure springs 16, the plurality of clamping blocks 10 cooperate with the arc-shaped clamping grooves 11, the clamping block 10 overcomes the pushing force of the sliding column 13 on the pressure transmission ball 14, the sliding column 13 drives the sliding sleeve 15 to slide and overcome the preset force of the pressure spring 16, the connecting rod 9 and the connecting sleeve 8 form an idle state, and then the central rod 3 stops rotating and the motor 7 is turned off, thereby avoiding overloading due to overloading of the motor 7. When it is necessary to adjust the preset force of the pressure spring 16, rotate the rotating sleeve 23 to drive a plurality of yielding grooves 24 to rotate to the top end of a plurality of limiting blocks 20, remove the abutment of the inner wall of the rotating sleeve 23 on the limiting block 20, and push the limiting block 20 outward and away from the limiting groove 22 through a plurality of push springs 21. The restriction on the adjusting sleeve is removed, the sliding adjusting sleeve pushes the sliding sleeve 15 through the push rod 18 and the abutting block 19 to press the pressure spring 16, thereby increasing the preset force of the pressure spring 16. Conversely, the pressure spring 16 extends to reduce the preset force. Then rotate the rotating sleeve 23 again, push the limiting block 20 to slide to the inner wall of the rotating sleeve 23 and apply pressure through the inclined surfaces at both ends of the yielding groove 24, and the limiting block 20 slides to the positioning groove and presses the plurality of push springs 21, thereby completing the positioning of the adjusting sleeve and the adjustment of the preset force of the pressure spring 16.

[0037] Please refer to Figure 5As an embodiment of the sealing mechanism: the shell 1 is provided with a sealing mechanism, which includes a limiting frame 29, a hydraulic cylinder 30, a push plate 31 and a sealing plate 32. The limiting frame 29 is installed on the outer wall of the shell 1, the hydraulic cylinder 30 is installed on the outer wall of the shell 1, the push rod 18 is installed on the telescopic end of the hydraulic cylinder 30, and the sealing plate 32 is installed at the bottom end of the push plate 31 and is in sliding connection with the limiting frame 29.

[0038] More specifically, the sealing mechanism adopts the mode of hydraulic cylinder 30 driving the push plate 31 to move, which drives the sealing plate 32 to accurately close under the guidance of the limiting frame 29. This design not only ensures the sealing of the mixing process, but also facilitates the feeding of raw materials and the taking out of finished products.

[0039] In summary, when the overall device is in use or operation: the over motor 7 drives the center rod 3 to rotate, driving multiple sets of mounting frames 4 to rotate. The stirring rods 5 and the breaking blocks 6 on the mounting frames 4 perform multi-level stirring and breaking of the feed additives in the mixing tank 2 during rotation. This design achieves a three-dimensional mixing effect, effectively preventing the stratification and caking of additives. The design of the feed pipe 25 and the top cover 26 at the top of the mixing tank 2 facilitates the feeding of raw materials while ensuring the sealing of the mixing process. When different components of raw materials appear to be caked or agglomerated during the mixing process, the center rod 3 will generate resistance. When the resistance is greater than the pre-set force of the multiple pressure springs 16, the multiple clamping blocks 10 cooperate with the arc-shaped clamping grooves 11, the clamping blocks 10 overcome the pushing force of the sliding column 13 on the transmission pressure ball 14, the sliding column 13 drives the sliding sleeve 15 to slide and overcome the pre-set force of the pressure spring 16, the connecting rod 9 and the connecting sleeve 8 form an idle state, and then the center rod 3 stops rotating and the motor 7 is turned off, which can avoid overloading caused by the motor 7. When it is necessary to adjust the pre-set force of the pressure spring 16, rotate the rotating sleeve 23 to drive the multiple let-in grooves 24 to rotate to the top end of the multiple limiting blocks 20, remove the abutment of the limiting blocks 20 on the inner wall of the rotating sleeve 23, and push the limiting blocks 20 outward and away from the limiting grooves 22 through the multiple push springs 21, which can remove the restriction on the adjusting sleeve. The sliding adjusting sleeve pushes the sliding sleeve 15 through the push rod 18 and the abutting block 19 to press the pressure spring 16, which can increase the pre-set force of the pressure spring 16. Conversely, the extension of the pressure spring 16 can reduce the pre-set force. Then rotate the rotating sleeve 23 again, push the limiting blocks 20 to slide to the inner wall of the rotating sleeve 23 and apply pressure through the inclined surfaces at both ends of the let-in grooves 24, slide the limiting blocks 20 to the positioning grooves and press the multiple push springs 21, complete the positioning of the adjusting sleeve, and then complete the adjustment of the pre-set force of the pressure spring 16.

[0040] The sealing mechanism adopts the mode of hydraulic cylinder 30 driving the push plate 31 to move, which drives the sealing plate 32 to accurately close under the guidance of the limiting frame 29. This design not only ensures the sealing of the mixing process, but also facilitates the feeding of raw materials and the taking out of finished products.

[0041] In all the above-mentioned solutions, the connection between the two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection or other known connection mode, which will not be described here. In the above, whenever there is a fixed connection, welding is preferred. Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
