When the discharge pipe 7 discharges materials, the through hole at the bottom of the screening frame 601 can be used for filtering and screening, and the agglomerated materials can be filtered out. In the process of discharging, the driving motor 602 can be started to drive the cam 603 to rotate, and then cooperate with the elastic force of the reset spring 610 to make the screening frame 601 slide back and forth to achieve vibration filtering and screening, thereby improving the screening effect of the material.

[0036] In this embodiment, through holes are opened at equal angles at the bottom of the screening frame 601, and the area of ​​the internal opening cross-section of the screening frame 601 is larger than the area of ​​the cross-section of the bottom end of the discharge pipe 7. The use of a larger area screening frame 601 facilitates centralized and comprehensive filtering and screening of materials discharged from the discharge pipe 7.

[0037] In this embodiment, a fixing bolt 607 extending into the interior of the slot 609 is movably connected to one side of the connecting seat 605, and a bolt hole 612 threadedly matched with the fixing bolt 607 is opened at the upper end of one side of the clamping block 611. The fixing bolt 607 is threadedly matched with the bolt hole 612 to achieve limited fixation of the clamping block 611 and the interior of the slot 609 after sliding engagement.

[0038] In this embodiment, an anti-slip ridge 608 is fixedly connected at an equal angle to one side of the surface of the fixing bolt 607. The cross-section of the anti-slip ridge 608 is arc-shaped. The arc-shaped anti-slip ridge 608 is used to increase the contact friction between the user's fingers and the nut of the fixing bolt 607, thereby facilitating the user to rotate the fixing bolt 607.

[0039] In this embodiment, a locking structure is formed between the card block 611 and the inside of the card slot 609. The cross-sections of the card slot 609 and the card block 611 are inverted convex. The sliding of the inverted convex card block 611 and the inside of the card slot 609 is utilized to improve the firmness and stability of the sliding installation between the screening frame 601 and the connecting seat 605.

[0040] In addition, a material guiding platform 5 is fixedly connected to the inner bottom wall of the shell 10 . The material guiding platform 5 is funnel-shaped. By using the funnel-shaped material guiding platform 5 , the materials can be discharged from the discharge pipe 7 in a more concentrated manner.

[0041] The working principle and use process of the utility model are as follows: first, raw materials are added into the shell 10 through the feed hopper 1, and then the servo motor 11 is started to rotate the spiral return rod 8, which can then drive the scraper 2 to rotate, so that the stirring rod 3 stirs the materials inside the shell 10 as it rotates, and the rotation of the scraper 2 can reduce the adhesion residue of the materials on the inner wall of the shell 10, thereby improving the utilization rate of the materials. At the same time, the spiral return rod 8 rotates to cooperate with the return barrel 9 to transport the materials at the lower end of the shell 10 upward, and discharge them from the opening at the top of the return barrel 9, thereby realizing the up and down stirring of the materials inside the shell 10, and then the materials can be quickly stirred by stirring the materials up and down and rotating, thereby avoiding the inconvenience caused by the inconvenience of stirring the materials at the lower end of the traditional shell 10, and improving the material stirring rate;

[0042] After the material is stirred evenly, the valve on the discharge pipe 7 is opened, and the funnel-shaped material guide table 5 is used to allow the material to be discharged from the discharge pipe 7 in a more concentrated manner. At the same time, the servo motor 11 is continued to be started to drive the spiral return rod 8 to work in the reverse direction, so that the material inside the return barrel 9 can be discharged quickly, and the spiral return rod 8 protruding from the lower end of the return barrel 9 can also exert a downward force on the material at the lower end of the shell 10, so as to facilitate the discharge of the material into the discharge pipe 7 for discharge;

[0043] At the same time, when the material is discharged from the discharge pipe 7, the through hole at the bottom of the screening frame 601 can be used for filtering and screening, so that the agglomerated materials can be filtered out, thereby improving the quality of the final discharged materials. In addition, during the discharge process, the driving motor 602 can be started to drive the cam 603 to rotate, and periodically contact the screening frame 601, so that the screening frame 601 slides and drives the slider 606 to slide inside the slide groove 604 to compress or stretch the reset spring 610. After the cam 603 rotates away, the elastic force of the reset spring 610 can be used to make the screening frame 601 slide back to its original position, and then the screening frame 601 slides back and forth to achieve vibration filtering and screening, thereby improving the screening effect of the material.

[0044] In addition, the sliding back and forth of the screening frame 601 will cause the connecting seat 605 to slide and collide with the surface of the discharge pipe 7, thereby realizing the vibration discharge of the discharge pipe 7. At the same time, after the mixing process is completed, the anti-slip convex strip 608 can be rotated until it is completely disengaged from the inside of the bolt hole 612, and then the screening frame 601 can be pulled hard to make the block 611 completely slide and disengage from the inside of the slot 609, so that the screening frame 601 can be disassembled and the agglomerated materials inside it can be processed centrally.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
