[0033] In this embodiment, support feet 10 are installed at the four corners of the bottom of the machine body 1, and the support feet 10 are fixedly connected to the machine body 1 through bolts. The support feet 10 play a stable supporting role for the machine body 1, ensuring the stability of the machine body 1.

[0034] In this embodiment, a discharge pipe 11 is installed at the bottom center of the machine body 1, and a valve is installed on the discharge pipe 11. The arrangement of the discharge pipe 11 facilitates the discharge of the machine body 1, and the arrangement of the valve facilitates the control of the discharge.

[0035] In this embodiment, the mounting plate 12 is provided with connecting bolts 14, and the connecting bolts 14 are threadedly connected to the ends of the cross beams 22. This connection method facilitates the disassembly and assembly of the cross beams 22, and further facilitates the disassembly and assembly of the agitator 2.

[0036] In this embodiment, the overall shape of the bracket 13 is U-shaped, and the bracket 13 and the mounting plate 12 are an integrally formed structure. The U-shaped design facilitates the bracket 13 to carry the beam 22, and the integrally formed design increases the structural strength of the bracket 13 and the mounting plate 12.

[0037] In this embodiment, guide rails 222 are fixedly connected to both side walls of the strip groove 221 by bolts, and both side outer walls of the connecting block 23 are provided with slide grooves slidably connected to the guide rails 222.

[0038] In this embodiment, the cross beams 22 are distributed in a circular shape with equal spacing, and the number of cross beams 22 is 2-4. The preferred number of cross beams 22 is 3, which is convenient for installing multiple first stirring shafts 25 around the first and second stirring shafts 26, thereby better stirring the various raw materials in the machine body 1.

[0040] It should be supplemented that both ends of the guide rail 222 in this embodiment are fixedly connected with limit pins 223 by bolts. The setting of the limit pins 223 limits the horizontal movement of the connecting block 23, thereby limiting the movement range of the first stirring blade 251, thereby preventing the first stirring blade 251 from being released to the machine body 1 or the second stirring blade 261.

[0041] It is worth noting that the first motor 21 and the second motor 27 involved in this embodiment are existing conventional technologies and will not be described in detail here.

[0042] During specific use, the user first turns on the power of the first motor 21 and the second motor 27, and the first motor 21 and the second motor 27 start working. The output shaft of the second motor 27 rotates to drive the first stirring shaft 25 and the first stirring blade 251 to stir the various raw materials in the machine body 1. At the same time, the output shaft of the first motor 21 continues to rotate forward and reverse and drives the main bevel gear 211 to rotate forward and reverse. The main bevel gear 211 also drives the second stirring shaft 26 and multiple second stirring blades 261 to rotate forward and reverse. At the same time, the main bevel gear 211 drives multiple secondary bevel gears 241 to rotate, and multiple screw rods 24 continue to rotate forward and reverse. At the same time, the connecting block 23 reciprocates horizontally along the strip groove 221, and drives the first stirring shaft 25 and the first stirring blade 251 to reciprocate horizontally. Under the continuous stirring of the first stirring blade 251 and the second stirring blade 261, the various raw materials of the molten iron casting release agent can be stirred and mixed.
