Secondly, when the gear 241 is meshed with the tooth height 232, the plurality of stirring cylinders 21 are in a low-level state at this time, and the pushing plate 265 is positioned in the upper cavity 251, so that raw materials in the upper cavity 251 enter the lower cavity 253 through the middle cavity 252, and the pushing plate 265 entering the upper cavity 251 can dredge the middle cavity 252, and move to a position with a larger table-shaped bottom surface of the upper cavity 251 along with the unfolding of the opening and closing plate 266, so that the unfolded opening and closing plate 266 dials away raw materials accumulated in the upper cavity 251 to avoid accumulation of raw materials; when the gear 241 is meshed from the high tooth position 232 to the low tooth position 233, the stirring cylinder 21 moves to the high position at this time so that the pushing plate 265 moves to the lower cavity 253 and pushes and conveys the raw materials when the pushing plate 265 passes through the middle cavity 252, so that the raw materials in the upper cavity 251 can be quickly conveyed to the lower cavity 253 under the action of the pushing plate 265, the spiral stirring blade 22 is convenient for discharging the raw materials, and meanwhile, the two plate ends push and scrape the side wall of the upper cavity 251 along with the opening and closing plate 266 in the upper cavity 251, so that the raw materials below the opening and closing plate 266 are reduced; when the gear 241 is meshed with the tooth lower portion 233, the plurality of stirring cylinders 21 are in a high-level state, the pushing plate 265 is positioned in the lower cavity 253, and raw materials conveyed in the middle cavity 252 completely enter the lower cavity 253 under the action of the pushing plate 265, so that pushing of the raw materials in the conveying cavity 25 is completed, meanwhile, the unfolded folding plate 266 in the lower cavity 253 is unfolded, the unfolded folding plate 266 extrudes and pushes the raw materials in the lower cavity 253 downwards, the raw materials accumulated in the lower cavity 253 can be rapidly discharged into the discharge holes 225 on the spiral stirring blades 22, otherwise, in the combining process of the folding plate 266 in the lower cavity 253, the two plate ends can scrape the inner walls of the lower cavity 253.

Moreover, when the gear 241 is meshed from the tooth high position 232 to the tooth low position 233, the stirring cylinder 21 moves to the high position to enable the pushing plate 265 to move downwards to the cavity 253, at the moment, the pushing rod 26 moves downwards under the action of the plug rod 271 to enable the first plug plate 272 to be pressed by the gas originally in the vertical cavity 27, simultaneously the pushing plate 265 is accompanied with the pushing plate 3 to pry the pulling plate 3, the end part of the pulling plate 3 in the material conveying cavity 25 moves downwards, the end part of the pulling plate 3 in the vertical cavity 27 moves upwards to enable the pulling plate 3 to push the second plug plate 31 upwards to enable the first plug plate 272 and the second plug plate 31 to be mutually close and compress the gas in the vertical cavity 27, simultaneously the pulling plate 3 pushes the second plug plate 31 to move upwards to enable the first plug plate 272 and the second plug plate 31 to be mutually close and compress the gas in the vertical cavity 27, and the second elastic member 311 is compressed and deformed during the upward movement of the second plug plate 31, and when the pushing plate 265 continues to move downward, the pulling plate 3 continues to move upward and separate from the second plug plate 31, at this time, the second plug plate 31 suddenly moves downward under the action of the restoring deformation of the second elastic member 311 and makes the second plug plate 31 suddenly strike the touch plate 33, so that the touch plate 33 suddenly moves downward and deforms with the fourth elastic member 331, and the pushing plate 265 also moves downward to the lowest position and enters into the lower cavity 253, and makes the pushing plate 265 abut against the touch plate 33, so that the shake generated by the impact of the second plug plate 31 on the touch plate 33 is transferred to the pushing plate 265, the vibration received by the pushing plate 265 is transferred to the symmetrically arranged opening and closing plates 266 through the pushing rod 26, the opening and closing plates 266 with vibration effects shake the raw materials in the upper cavity 251 and the lower cavity 253, the situation that raw materials in the material conveying cavity 25 are accumulated and agglomerated is reduced, and the perforation is opened by the fourth elastic piece 331 along with deformation, so that air compressed by the first plug plate 272 and the second plug plate 31 can quickly pass through the position of the fourth elastic piece 331 in the perforation, compressed gas enters the middle cavity 252 and is divided into two parts to be diffused, and the first part of gas enters the upper cavity 251 through the middle cavity 252, so that raw materials originally positioned in the upper cavity 251 are blown by airflow to be kept loose, and the material pushing plate 265 is convenient for conveying raw materials; the second part of gas enters the lower cavity 253 through the middle cavity 252, so that the lower cavity 253 can spray out mixed gas of raw materials in the discharge hole 225 in the process of conveying the raw materials to the discharge hole 225, the spiral stirring blade 22 can conveniently and rapidly discharge the raw materials into the tank body 1, and the situation that the port of the discharge table hole 226 is blocked is reduced.

Finally, in the process of continuing to move downwards through the pushing plate 265, the poking plate 3 is further moved upwards and separated from the second plug plate 31, at the moment, the second plug plate 31 is suddenly moved downwards under the action of the recovery deformation of the second elastic piece 311, and the second plug plate 31 is made to suddenly impact the contacted plate 33, so that the contacted plate 33 suddenly moves downwards and is accompanied with the deformation of the fourth elastic piece 331, and the second plug plate 31 reaches the position of the vent hole 332, so that the vertical air cavity 27 can keep open upwards and downwards, thereby enabling the air compressed by the first plug plate 272 and the second plug plate 31 to have a third part to be used, and the air of the third part enters into the air flow hole 361 through the winding hole 36 and is sprayed out of the front surface 223 and the back surface 224 of the blade 221 through the action of the symmetrically arranged table ring hole 362; when the gear 241 is meshed with the teeth lower position 233, the stirring cylinders 21 are in a high position state, the blades 221 on the spiral stirring blades 22 are in a high position state, the air flow holes 361 at the moment enable the annular ring holes 362 to be communicated close to the front surfaces 223 on the blades 221, so that smaller bubbles are ejected from the annular ring holes 362 and enter the stock solution under a stronger stock solution head-on state of the blades 221 when the blades 221 rotate, the extrusion effect of the small bubbles on the stock solution is improved, and the mixing efficiency of the stock solution and the raw materials in the tank body 1 is improved; when the gear 241 is engaged with the tooth high position 232, the plurality of stirring cylinders 21 are in a low position state, the impeller 221 on the spiral stirring blade 22 is in a low position state, the air flow holes 361 at the moment enable the annular ring holes 362 to be communicated with the back 224 on the impeller 221, so that the cavity formed by the back 224 of the impeller 221 is larger under the weaker primary liquid head-on state of the impeller 221 when the impeller 221 rotates, larger bubbles are ejected out of the annular ring holes 362 and mixed with the cavity at the moment, and then the bigger bubbles enter the primary liquid, so that the larger bubbles increase the additional extrusion effect on the primary liquid, the mixing efficiency of the primary liquid and raw materials in the tank body 1 is increased, the larger bubbles and the small bubbles are mutually mixed, the primary liquid is extruded additionally, and the mixing effect of the primary liquid and the raw materials is greatly improved.
