[0024] The shifting mechanism is used to drive the agitator to move. The agitator has various stations on its moving stroke for stirring the materials in various material containers. Two material containers correspond to two stations of the agitator, forming a double-station stirring device, such as Figure 2 As shown, the shifting mechanism switches the working position of the agitator by driving the agitator to move, so that the agitator can be stirred in different material containers. When one material container is stirring materials, the other material container can be unloading and adding materials, which is beneficial to the continuous use of the agitator. The two material containers can alternately perform stirring, adding and unloading operations, which is beneficial to continuous production. The shifting mechanism includes a lifting mechanism and a rotating mechanism. The lifting mechanism is used to drive the agitator to lift and lower so that the agitator enters and exits the material container. The rotating mechanism is used to drive the agitator to rotate so that the agitator moves from one material container to another. The lifting mechanism and the rotating mechanism cooperate to switch the working position of the agitator. The shifting mechanism also includes a rotating limiting structure for limiting the agitator when the agitator rotates to the corresponding working position and a lifting limiting structure for limiting the lifting range of the agitator.

The rotating mechanism, the rotating limiting structure, and the lifting limiting structure are combined in the following text. Figure 3 Provide explanation.

[0025] The lifting mechanism includes a hydraulic support 301, which is a hydraulic cylinder equipped with a hydraulic station 307. Each material container is arranged around the hydraulic support 301, and each material container is at the same distance from the hydraulic support 301. The cylinder body of the hydraulic support 301 constitutes a fixed part fixed to the support frame 100, and the telescopic rod constitutes a movable part that can be lifted and lowered relative to the fixed part.

[0026] The rotating mechanism includes a rotating mounting structure for rotating the agitator, the rotating mounting structure is arranged at the upper end of the telescopic rod of the hydraulic support 301, the rotating mounting structure is a bearing, a rotating sleeve is fixedly arranged at the bottom of the top frame 406 of the agitator, and the rotating sleeve is installed at the upper end of the telescopic rod through a bearing so that the agitator can rotate with the telescopic rod as the axis. In order to facilitate the rotation of the agitator, the rotating mechanism also includes a transmission rod 303 and a transmission gear set 302, the transmission gear set 302 includes a large gear 3021 and a small gear 3022, the large gear 3021 is fixedly installed at the bottom of the top frame 406 of the agitator and is coaxially arranged with the rotating sleeve. The telescopic rod of the hydraulic prop 301 is also fixed with a mounting plate 308, which is located below the large gear 3021. A transmission rod support 309 is fixed on the mounting plate 308. The transmission rod support 309 is provided with a through hole for the transmission rod 303 to pass through, and the transmission rod 303 can rotate in the through hole of the transmission rod support 309. The mounting plate 308 and the transmission rod support 309 together constitute a support seat on the movable part. The transmission rod support 309 is provided with a limiting structure for limiting the transmission rod 303 in the up and down directions so that the transmission rod 303 can be lifted and lowered with the telescopic rod of the hydraulic prop 301. The limiting structure can be a retaining ring set on the transmission rod 303, which is matched with the transmission rod support 309 in the up and down directions to achieve limiting. The pinion 3022 is installed on the upper end of the transmission rod 303 that passes through the transmission rod support 309 upward.

[0027] A mounting seat 314 is also fixed to the upper part of the cylinder body of the hydraulic prop 301. The mounting seat 314 has an inner cavity. A bevel gear set is installed in the inner cavity of the mounting seat 314. The bevel gear set includes a driving gear and a driven gear.

The inner portion of the rotation-stopping mounting hole is provided with a rotation-stopping mounting hole. A guide key is provided on the wall, and a guide groove 3031 is provided on the transmission rod to cooperate with the guide key. The guide groove 3031 extending up and down can guide the transmission rod 303 relative to the driven gear in the up and down direction. When the hand wheel 310 is rotated, the driving gear of the bevel gear set is driven to rotate, the driving gear drives the driven gear to rotate, and the driven gear drives the transmission rod 303 to rotate. When the transmission rod 303 rotates, the agitator is driven to rotate through the transmission gear set 302 to move the agitator from one kettle body 201 to another kettle body 201. When the hydraulic support 301 is extended and the telescopic rod drives the agitator to rise and fall, the mounting plate 308 and the transmission rod 303 can be lifted and lowered together. The transmission rod 303 can move up and down relative to the drive sleeve, and can also be driven to rotate by the drive sleeve to adapt to the lifting and rotating process of the agitator.

[0028] A sealing installation hole for the stirring main shaft 405 to pass through is provided at the center of the kettle cover 202. The stirring main shaft 405 can rotate relative to the kettle cover 202, and when the stirrer is raised or lowered, the kettle cover 202 is raised or lowered along with the stirrer. The stirring frame 407 is used to extend into the kettle body 201 to stir the materials in the kettle body 201. The kettle cover 202 constitutes a cover body, and a kettle cover 202 that moves and changes position along with the stirrer can meet the requirements of sealing the openings of different kettle bodies 201, which is conducive to cost saving.

[0029] The mounting plate 308 is provided with a first rotation limit rod 304 and a second rotation limit rod 305 extending upward, and the downward end surface of the large gear 3021 is provided with two limit grooves for the first rotation limit rod 304 and the second rotation limit rod 305 to extend into respectively, and the rotation limit rod cooperates with the limit groove to limit the rotation range of the top frame 406 of the agitator, and the first rotation limit rod 304 and the second rotation limit rod 305 constitute a rotation limit structure for limiting the agitator when the agitator rotates to the corresponding working position, and when the agitator frame 407 of the agitator moves from above one kettle body 201 to above another kettle body 201, the rotation limit rod cooperates with the corresponding groove wall of the limit groove to facilitate the agitator to move into place.

[0030] The lifting limit structure includes a lifting limit rod 306 and a travel switch 311 extending up and down. A limit rod support is provided on the cylinder body of the hydraulic support 301. The limit rod support is provided with a through hole for the lifting limit rod 306 to pass through. The upper end of the lifting limit rod 306 is fixed to the mounting plate 308 by a fixing rod. Travel switches 311 are respectively provided at the through holes on the upper and lower sides of the limit rod support. The lifting limit rod 306 is provided with an upper limit sleeve 312 and a lower limit sleeve 313 spaced apart from each other. The upper limit sleeve 312 and the lower limit sleeve 313 are respectively located on the upper and lower sides of the limit rod support. When the upper limit sleeve 312 hits the upper travel switch, the agitator drops into place. When the lower limit sleeve 313 hits the lower travel switch, the agitator rises into place. After the agitator finishes stirring the material in one of the kettle bodies 201, the agitator is first raised to separate from the kettle body 201, and then the agitator is rotated to move the agitator above the other kettle body 201, and then the agitator is lowered to allow the agitator's stirring frame 407 to enter the corresponding kettle body 201, thereby completing the workstation switching.

[0031] Four weighing sensors 500 are arranged on the support frame 100 at the periphery of the kettle body 201. The weighing sensors 500 are evenly distributed. The weighing sensors 500 are connected to the kettle body 201 to measure the weight of the kettle body 201 and the material inside. The weighing sensors 500 constitute a weight detector. Since the weight of the kettle body 201 is constant, the weight of the kettle body 201 can be removed during measurement. When adding materials, the weight of the materials can be monitored in real time through the weighing sensors 500, and the addition of materials is stopped when the weight required for production is reached. A control cabinet 600 is also arranged on the support frame 100. The control cabinet 600 is used to control the corresponding motors and the hydraulic station 307 to control the action of the entire stirring device.

[0032] In other embodiments, there may be three material containers, each of which is arranged around the hydraulic support. To avoid interference between the rotation limit rod and the top frame of the agitator, the rotation limit rod may be eliminated, and the rotation range of the agitator may be controlled by controlling the rotation angle of the output shaft of the rotating motor.
