A mounting plate 2 is provided between the left and right sides of the upper part of the mixing frame 1 by bolts, a cylinder 3 is installed on the top of the mounting plate 2, a connecting plate 4 is connected to the telescopic rod of the cylinder 3, lifting rods 5 are welded on the left and right sides of the connecting plate 4, a first agitator 6 is rotatably provided between the bottom ends of the two lifting rods 5, a shielding door 9 is rotatably provided on the front right side of the mixing frame 1, and the shielding door 9 can be stuck in the mixing frame 1, and also includes a first screw 7 and a second agitator 8. The left and right sides of the bottom of the first agitator 6 are connected to the second agitator 8, the middle side of the bottom of the mounting plate 2 is connected to the first screw 7, and the first agitator 6 rotates on the first screw 7.

[0024] When the staff needs to use the device, the staff places the device in a suitable position, and then the staff pours the raw materials to be mixed into the mixing frame 1. After pouring, the staff starts the cylinder 3, and the telescopic rod of the cylinder 3 drives the connecting plate 4 to move up and down, and the connecting plate 4 drives the lifting rod 5 to move up and down, and the lifting rod 5 drives the first agitator 6 to move up and down. At the same time, the first agitator 6 rotates on the first screw 7, and the first agitator 6 drives the second agitator 8 to move up and down and rotate, so that the first agitator 6 and the second agitator 8 simultaneously stir the mixture in the mixing frame 1, so as to achieve the purpose of more uniform mixing of the mixture and faster mixing speed. After the mixing is completed, the staff closes the cylinder 3, and then the staff opens the shielding door 9 to take out the mixture in the mixing frame 1.

[0025] Example 2

[0026] Based on Example 1, see Figure 1 and Figure 3 As shown, it also includes a bottom plate 10, a fixed block 11, a connecting rotating plate 12, a slider 13, a fixing plate 14 and a first elastic member 15. The bottom of the mixing frame 1 is provided with the bottom plate 10 by bolts, and the front and rear sides of the bottom of the bottom plate 10 are symmetrically provided with fixing blocks 11 by bolts, and a connecting rotating plate 12 is welded between the front and rear fixing blocks 11. The front and rear sides of the upper part of the fixing plate 14 are symmetrically provided with sliders 13 in a sliding manner, and the connecting rotating plate 12 rotates between the front and rear sliders 13. The first elastic member 15 is connected between the slider 13 and the fixing plate 14.

[0027] See also Figure 5 As shown, a guide pipe 24 is also included, and the bottom of the blanking frame 18 is connected and communicated with the guide pipe 24.

[0028] When the staff needs to mix the raw materials, the staff starts the motor 16, and the output shaft of the motor 16 rotates to drive the second screw 17 to rotate, and the second screw 17 drives the discharge frame 18 to move left and right. Then the staff pours the two raw materials that need to be mixed and stirred into the discharge frame 18 respectively, and the raw materials in the discharge frame 18 flow into the mixing frame 1 through the guide tube 24. The guide tube 24 guides the raw materials to prevent the raw materials from falling out of the mixing frame 1. At the same time, the discharge frame 18 drives the raw materials to move left and right, and then the discharge frame 18 falls evenly into the mixing frame 1, so as to facilitate the agitator to stir the raw materials. When the raw materials are stirred, the staff turns off the motor 16 and takes out the mixed materials.

[0029] See also Figure 1 As shown, it also includes a motor 16, a second screw 17 and a blanking frame 18. The motor 16 is installed on both the front and rear sides of the upper left part of the mounting plate 2. The output shaft of the motor 16 is connected to the second screw 17 through a coupling. The blanking frame 18 is threadedly arranged on the second screw 17.

[0030] When the agitator stirs the raw materials, the mixing frame 1 vibrates and drives the bottom plate 10 to move up and down, the bottom plate 10 drives the fixed block 11 to move up and down, the fixed block 11 drives the connecting rotating plate 12 to rotate downward, the connecting rotating plate 12 rotates downward between the two sliders 13, and at the same time the connecting rotating plate 12 squeezes the slider 13 backward, the first elastic member 15 is deformed accordingly, and then the first elastic member 15 buffers the mixing frame 1, thereby preventing the mixing frame 1 from vibrating continuously and affecting the mixing; when the mixing frame 1 no longer vibrates, the first elastic member 15 drives the slider 13 to move inward and reset, the slider 13 drives the connecting rotating plate 12 to rotate upward, the connecting rotating plate 12 drives the fixed block 11 to move upward, the fixed block 11 drives the bottom plate 10 to move upward, and the bottom plate 10 drives the mixing frame 1 to move upward and reset.

[0031] See also Figure 4 As shown, it also includes a support plate 19, a pressing plate 20, a scraper 21 and a second elastic member 22. The support plate 19 is welded between the left and right sides of the upper rear part of the mixing frame 1, and a scraper 21 is slidably arranged between the left and right sides of the support plate 19. The scraper 21 is located in the mixing frame 1, and the pressing plate 20 is welded between the left and right sides of the upper part of the scraper 21. The second elastic member 22 is sleeved on both sides of the scraper 21, and the upper and lower ends of the second elastic member 22 are respectively connected to the support plate 19 and the pressing plate 20.

[0032] When the raw materials are stirred, the staff squeezes the pressing plate 20 downward, and the pressing plate 20 drives the scraper 21 to move downward in the support plate 19, and the second elastic member 22 is deformed accordingly, so that the scraper 21 contacts the mixing frame 1 and scrapes off the raw materials on the surface of the mixing frame 1, thereby facilitating the cleaning of the mixing frame 1. After cleaning, the staff releases the pressing plate 20, and the second elastic member 22 drives the pressing plate 20 to move upward and reset, and the pressing plate 20 drives the scraper 21 to move upward and reset.

[0033] See also Figure 2 As shown, cones 23 are also included, and multiple cones 23 are evenly spaced and connected on both sides of the mixing frame 1.

[0034] The cone 23 is used to stir the raw material, and when the stirrer stirs the raw material, the cone 23 repeatedly contacts the raw material, and the cone 23 mixes the raw material.
