[0015] The present invention has the following beneficial effects:

[0016] (1) According to the present invention, the material is poured into the interior of the mixing barrel, and the motor is started. The motor drives the rotating shaft to rotate, the rotating shaft drives the fixed frame to rotate, the fixed frame drives the inclined shell to rotate, the inclined shell drives the elastic stirring rod to rotate, and the elastic stirring rod stirs the material during the rotation process. At the same time, the rotating shaft drives the reciprocating screw to rotate. The reciprocating screw drives the threaded ring to reciprocate up and down along the outer wall of the limiting rod under the limit position. The threaded ring drives the mixing frame to descend, the mixing frame drives the sliding rod to descend, and the sliding rod drives the special-shaped frame to descend. During the descent process of the special-shaped frame, it will contact one end of the elastic stirring rod, so that the elastic stirring rod is elastically pressed down. When the special-shaped frame is no longer in contact with the elastic stirring rod, the elastic stirring rod is subjected to its own elastic deformation to swing up and down, thereby accelerating the stirring effect of the elastic stirring rod on the material, reducing the accumulation of the material inside the mixing barrel, and reducing the probability of material leakage.

[0017] (2) According to the present invention, when the stirring frame is raised or lowered, the flexible rod will be driven to move up or down because the flexible rod slides inside the inclined shell, thereby driving the flexible rod to rotate during the rotation of the inclined shell, and the flexible rod drives the stirring frame to rotate, and the stirring frame drives the round tube to rotate. During the rotation of the round tube, the material inside the stirring barrel can be stirred, further reducing the squeezing of the material. At the same time, when the special-shaped frame is raised, the special-shaped frame no longer contacts the elastic stirring rod and is elastically squeezed by the spring. The spring drives the special-shaped frame to gradually move away from the stirring frame, and the special-shaped frame drives the sliding rod to move, and the sliding rod drives the fixed rod to move, and the fixed rod drives the conical piston rod to move toward the inside of the round tube. During the movement of the conical piston rod, the airflow inside the round tube enters into the inside of the stirring barrel through the leak plate, thereby causing the material to move downward, further reducing the accumulation of the material and preventing the occurrence of material channeling.

[0018] (3) In the present invention, when the tapered piston rod moves toward the inside of the circular tube, due to the tapered setting of the tapered piston rod, the tapered piston rod will contact the side wall of the tapered slider, so that the tapered slider slides inside the horizontal tube, and the tapered slider drives the stirring plate to move, and the stirring plate moves toward the inside of the stirring barrel. When the stirring plate enters the inside of the stirring barrel, as the stirring frame rotates, the stirring plate and the stirring frame stir together inside the stirring barrel, thereby improving the stirring efficiency of the material inside the stirring barrel and reducing the occurrence of material accumulation. Through the setting of the leakage plate, the material can be prevented from entering the inside of the circular tube, thereby improving the protective effect of the device.

[0019] (4) In the present invention, when the tapered piston rod moves toward the inside of the circular tube, the tapered piston rod drives the rotating bar to move. Due to the setting of the square groove, the rotating bar drives the sliding frame to move along the inner wall of the square groove, the sliding frame drives the circular frame to move, and the circular frame drives the impact arc plate to move. During the movement of the impact arc plate, it collides with the inner wall of the mixing barrel, causing the inner wall of the mixing barrel to vibrate slightly, thereby preventing the residual material from adhering to the dead corners of the mixing barrel, so that the material maintains fluidity and further prevents the accumulation of the material. In addition, during the process of the fixed frame driving the inclined shell to rotate, the inclined shell contacts around the inner wall of the mixing barrel, further preventing the material from adhering to the dead corners of the inner wall of the mixing barrel.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The elastic stirring rod 553 stirs the material during its rotation.

[0039] An auxiliary component 56 is provided on the outer wall of the reciprocating screw rod 54, and the auxiliary component 56 includes a threaded ring 561 threadedly connected to the outer wall of the top end of the reciprocating screw rod 54, and four limit rods 562 are fixedly connected to the bottom of the cross 53 around, one end of the limit rod 562 passes through the threaded ring 561 and extends to the outside of the threaded ring 561, and the outer wall of the limit rod 562 is rotatably connected to a stirring frame 563.

[0040] Four vertical rods 564 are fixedly connected to the top of the limiting rod 562, one end of the vertical rod 564 passes through the cross 53 and extends to the outside of the cross 53, and a protective shell 565 is fixedly connected to the top of the vertical rod 564. The protective shell 565 is provided to prevent external impurities from falling into the inside of the mixing barrel 3. Four flexible rods 566 are fixedly connected to the bottom of the mixing frame 563. The material of the flexible rods 566 is flexible and can be slightly bent. The outer wall of the bottom end of the flexible rod 566 is slidably connected to the inner wall of the inclined shell 552.

[0041] The top of the stirring frame 563 is provided with an anti-material-slipping assembly 57, which includes a sliding rod 571 that penetrates and is slidably connected to the top of the stirring frame 563. The bottom of the sliding rod 571 is fixedly connected to a special-shaped frame 572. The rotating shaft 52 drives the reciprocating screw rod 54 to rotate. The reciprocating screw rod 54 is limited by the limiting rod 562, and the reciprocating screw rod 54 drives the threaded ring 561 to reciprocate up and down along the outer wall of the limiting rod 562. The threaded ring 561 drives the stirring frame 563 to descend, and the stirring frame 563 drives the sliding rod 571 to descend, and the sliding rod 571 drives the special-shaped frame 572 to descend. The shaped frame 572 is in descending motion. During the descending process, the shaped frame 572 will come into contact with one end of the elastic stirring rod 553, causing the elastic stirring rod 553 to be elastically pressed downward. When the shaped frame 572 is no longer in contact with the elastic stirring rod 553, the elastic stirring rod 553 swings up and down due to its own elastic deformation, thereby accelerating the stirring effect of the elastic stirring rod 553 on the material, reducing the accumulation of materials inside the stirring barrel 3, and reducing the probability of material leakage on the side. The shaped frame 572 is fixedly connected to a spring 573 on one side close to the sliding rod 571, and the top of the spring 573 is fixedly connected to the bottom of the stirring frame 563.

[0042] A fixed rod 574 is fixedly connected to one side of the top of the sliding rod 571, and one end of the fixed rod 574 is fixedly connected to a tapered piston rod 576. A circular tube 575 is connected to the top of the stirring frame 563 near the sliding rod 571. When the stirring frame 563 is lifted or lowered, the flexible rod 566 is driven to lift or lower. Because the flexible rod 566 slides inside the inclined shell 552, the flexible rod 566 is driven to rotate during the rotation of the inclined shell 552. The flexible rod 566 drives the stirring frame 563 to rotate, and the stirring frame 563 drives the circular tube 575 to rotate. During the rotation of the circular tube 575, the material inside the stirring barrel 3 can be stirred, further reducing the pushing of the material. The outer wall of the tapered piston rod 576 is slidably connected to the inner wall of the circular tube 575. One side of the outer wall of the circular tube 575 is respectively connected to three horizontal tubes 577, and the inner wall of the horizontal tube 577 is slidably connected to a tapered sliding block 578.

[0043] One end of the conical slider 578 is fixedly connected to a squeezing spring 579, and one end of the squeezing spring 579 is fixedly connected to one side of the inner wall of the transverse tube 577. One end of the conical slider 578 close to the squeezing spring 579 is fixedly connected to a stirring plate 5710. When the conical piston rod 576 moves toward the inside of the circular tube 575, the conical piston rod 576 contacts the side wall of the conical slider 578 due to the conical setting of the conical piston rod 576, so that the conical slider 578 slides inside the transverse tube 577, and the conical slider 578 drives the stirring plate 5710 to move, and the stirring plate 5710 moves toward the inside of the stirring barrel 3. When the stirring plate 5710 enters the inside of the stirring barrel 3, as the stirring frame 563 rotates, the stirring plate 5710 and the stirring frame 563 stir together inside the stirring barrel 3, thereby improving the material The stirring efficiency of the material inside the mixing barrel 3 is improved, and the accumulation of the material is reduced on the side. The bottom of the circular tube 575 is fixedly connected with a leak plate 5711. When the special-shaped frame 572 rises, the special-shaped frame 572 no longer contacts the elastic stirring rod 553, and is elastically squeezed by the spring 573. The spring 573 drives the special-shaped frame 572 to gradually move away from the stirring frame 563, and the special-shaped frame 572 drives the sliding rod 571 to move, and the sliding rod 571 drives the fixed rod 574 to move, and the fixed rod 574 drives the tapered piston rod 576 to move toward the inside of the circular tube 575. During the movement of the tapered piston rod 576, the airflow inside the circular tube 575 enters the inside of the mixing barrel 3 through the leak plate 5711, so that the material moves downward, further reducing the accumulation of the material and preventing the occurrence of material channeling.

[0044] In embodiment 2, an impact assembly 58 is provided on the top of the stirring frame 563, and the impact assembly 58 includes four square grooves 581 opened around the top of the stirring frame 563, and the two ends of one side of the conical piston rod 576 are rotatably connected with a rotating bar 582 respectively, and the end of the rotating bar 582 away from the conical piston rod 576 is rotatably connected with a sliding frame 583, and the outer wall of the bottom end of the sliding frame 583 is slidably connected to the inner wall of the square groove 581.

[0045] A round frame 584 is penetrated and slidably connected at the center of one side of the sliding frame 583, and a return spring 585 is fixedly connected to the side wall of one end of the round frame 584. One end of the return spring 585 is fixedly connected to the side wall of the sliding frame 583, and one end of the round frame 584 is fixedly connected to the impact arc plate 586. The side wall of the impact arc plate 586 is contacted with one side of the inner wall of the bracket shell 1. When the tapered piston rod 576 moves into the circular tube 575, the tapered piston rod 576 drives the rotating bar 582 to move. Due to the setting of the square groove 581, the rotating bar 582 drives the sliding frame 583 along the square groove 58 1 moves, the sliding frame 583 drives the round frame 584 to move, the round frame 584 drives the impact arc plate 586 to move, and the impact arc plate 586 collides with the inner wall of the mixing barrel 3 during the movement, causing the inner wall of the mixing barrel 3 to vibrate slightly, thereby preventing the material residue from adhering to the dead corner of the mixing barrel 3, so that the material maintains fluidity and further prevents the material from piling up. In addition, when the fixed frame 551 drives the inclined shell 552 to rotate, the inclined shell 552 contacts around the inner wall of the mixing barrel 3, further preventing the material from adhering to the dead corner of the inner wall of the mixing barrel 3.

[0046] When in use, pour the material into the mixing barrel 3, start the motor 51, the motor 51 drives the rotating shaft 52 to rotate, the rotating shaft 52 drives the fixing frame 551 to rotate, the fixing frame 551 drives the inclined shell 552 to rotate, the inclined shell 552 drives the elastic stirring rod 553 to rotate, and the elastic stirring rod 553 stirs the material during its rotation. At the same time, the rotating shaft 52 drives the reciprocating screw rod 54 to rotate, which is limited by the limiting rod 562, and the reciprocating screw rod 54 drives the threaded ring 561 to reciprocate up and down along the outer wall of the limiting rod 562. The threaded ring 561 drives The movable stirring frame 563 descends, and the stirring frame 563 drives the sliding rod 571 to descend, and the sliding rod 571 drives the special-shaped frame 572 to descend. During the descending process, the special-shaped frame 572 will contact one end of the elastic stirring rod 553, so that the elastic stirring rod 553 is elastically pressed down. When the special-shaped frame 572 is no longer in contact with the elastic stirring rod 553, the elastic stirring rod 553 swings up and down due to its own elastic deformation, thereby accelerating the stirring effect of the elastic stirring rod 553 on the material, reducing the accumulation of materials inside the stirring barrel 3, and reducing the probability of material leakage.

[0047] When the stirring frame 563 is raised or lowered, the flexible rod 566 is driven to rise or fall, because the flexible rod 566 slides inside the inclined shell 552, so that the inclined shell 552 drives the flexible rod 566 to rotate during its rotation, and the flexible rod 566 drives the stirring frame 563 to rotate, and the stirring frame 563 drives the round tube 575 to rotate. During the rotation of the round tube 575, the material inside the stirring barrel 3 can be stirred, which further reduces the crowding of the material. At the same time, when the special-shaped frame 572 is raised, the special-shaped frame 572 no longer contacts the elastic stirring rod 553. Under the elastic compression of spring 573, spring 573 drives the special-shaped frame 572 to gradually move away from the stirring frame 563, the special-shaped frame 572 drives the sliding rod 571 to move, the sliding rod 571 drives the fixed rod 574 to move, and the fixed rod 574 drives the conical piston rod 576 to move toward the inside of the circular tube 575. During the movement of the conical piston rod 576, the air flow inside the circular tube 575 passes through the leakage plate 5711 and enters the interior of the stirring barrel 3, so that the material moves downward, further reducing the accumulation of the material and preventing the occurrence of material channeling.

[0048] When the conical piston rod 576 moves toward the inside of the circular tube 575, due to the conical setting of the conical piston rod 576, the conical piston rod 576 will contact the side wall of the conical slider 578, so that the conical slider 578 slides inside the cross tube 577, and the conical slider 578 drives the stirring plate 5710 to move, and the stirring plate 5710 moves toward the inside of the stirring barrel 3. When the stirring plate 5710 enters the inside of the stirring barrel 3, as the stirring frame 563 rotates, the stirring plate 5710 and the stirring frame 563 stir the inside of the stirring barrel 3 together, thereby improving the stirring efficiency of the material inside the stirring barrel 3 and reducing the occurrence of material accumulation. Through the setting of the leakage plate 5711, the material can be prevented from entering the inside of the circular tube 575, thereby improving the protection effect of the device.

[0049] When the tapered piston rod 576 moves toward the inside of the circular tube 575, the tapered piston rod 576 drives the rotating bar 582 to move. Due to the setting of the square groove 581, the rotating bar 582 drives the sliding frame 583 to move along the inner wall of the square groove 581, and the sliding frame 583 drives the round frame 584 to move. The round frame 584 drives the impact arc plate 586 to move. During the movement of the impact arc plate 586, it will collide with the inner wall of the mixing barrel 3, causing the inner wall of the mixing barrel 3 to vibrate slightly, thereby preventing the residual material from adhering to the dead corner of the mixing barrel 3, so that the material maintains fluidity and further prevents the accumulation of the material. In addition, during the process of the fixed frame 551 driving the inclined shell 552 to rotate, the inclined shell 552 contacts around the inner wall of the mixing barrel 3, further preventing the material from adhering to the dead corner of the inner wall of the mixing barrel 3.
