[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) The driven stirring shaft revolves around the rotating disc, so that the driven stirring rod on the driven stirring shaft can preliminarily stir the raw materials while revolving in the kettle body, thereby tearing and displacing the raw materials that are stuck together, and can drive these raw materials to move, so as to avoid long-term accumulation in one place and sticking to each other, which makes it difficult to break them up; at the same time, the reciprocating movement of the reciprocating rack makes it continuously mesh with the rotating gear, so that the rotating gear reciprocates and drives the driven stirring shaft to rotate, so that the driven stirring rod on the driven stirring shaft is in a state of self-rotation while revolving, so as to further tear and pull the raw materials that are displaced by the tearing, thereby breaking up the clumping raw materials that are stuck together, and avoiding the raw materials sticking to each other in the kettle body to form clumps that are difficult to separate, thereby improving the stirring effect of the equipment, and making the raw materials in the kettle body uniform while making the ingredients in the drug preparation uniform, avoiding affecting the safety and effectiveness of the drugs, and at the same time reducing the time required for stirring and mixing the drugs, avoiding the raw materials sticking in the kettle body and increasing the stirring time, further improving the stirring efficiency and effect of the equipment, and reducing the limitations of the device when in use; (2) Both disassembly and assembly square plates move toward the direction of the stirring motor and contact it, and the vertical block of the disassembly and assembly L block on the disassembly and assembly square plate will also contact the stirring motor, thereby clamping the stirring motor at the current position, completing the installation operation of the stirring motor, so that it can provide a power source for the raw materials in the kettle body when stirring at the current position, avoiding the phenomenon of dislocation of the stirring motor during use, thereby improving the safety of the stirring motor during use; at the same time, through the continued movement of the guide block, the combined horizontal plate moves on the upper limit of the combined square column, so that the combined spring is in a buffering state, thereby strengthening the contact strength between the disassembly and assembly square plate and the vertical block of the disassembly and assembly L block and the stirring motor, and under the action of the buffer rubber pad, the friction force of the contact with the stirring motor can be further improved, thereby improving The installation effect of the stirring motor is improved; and the horizontal block on the disassembly L block is moved to the top of the stirring motor, so that the top of the stirring motor is limited to prevent it from moving during use; when the stirring motor needs to be disassembled, it is only necessary to reset and rotate the guide screw rod so that the disassembly square plate and the vertical block and the horizontal block of the disassembly L block are no longer in contact with the stirring motor, thereby releasing the limit setting of the stirring motor, and completing the disassembly operation of the stirring motor, making the installation and disassembly of the stirring motor convenient and quick, and can be completed without the aid of any tools, reducing the limitations of the equipment during use, and at the same time allowing the equipment to replace and use stirring motors of different models and powers according to different conditions such as stirring requirements, further improving the stirring effect of the equipment; (3) When the pressure cam rotates, it causes the pressure cross block to reciprocate, thereby driving the first scraper block to reciprocate under the action of the bent square rod, so that it can reciprocate on the driven stirring shaft, so that the raw materials adhered to the driven stirring shaft during stirring can be scraped off. At the same time, since a number of driven stirring rods are arranged on the driven stirring shaft, the side wall of the driven stirring shaft is not smooth. It is worth mentioning that the first scraper block is located on the driven stirring shaft between the two driven stirring rods, and there is a certain distance between each driven stirring rod. The first scraper block is located within this distance, so that the first scraper block can avoid being obstructed when scraping the raw materials adhered to the driven stirring shaft. At the same time, it can also scrape the raw materials adhered to the driven stirring shaft to the greatest extent, so that the reciprocating first scraper block can continuously scrape off the raw materials adhered to it during the stirring process of the driven stirring shaft, avoiding the defect of the configured raw materials. At the same time, these scraped raw materials will fall into the kettle for stirring again, thereby improving the use effect of the equipment; (4) Press the stirring motor so that the rubber elastic pad on the rectangular frame it contacts is in a buffering state, and at the same time, the positioning column on the rectangular frame moves within the positioning square tube, so that the positioning spring is in a buffering state. When the top of the stirring motor is limited by the vertical block on the disassembled L block, the positioning spring and the rubber elastic pad in the buffering state cannot be reset due to the premise of being limited, and the elastic force brought about will act on the stirring motor, thereby strengthening the contact strength between the stirring motor and the vertical block on the disassembled L block, so that the two are against each other, avoiding the existence of a gap that causes the stirring motor to shake during use; at the same time, the buffering force brought by the positioning spring and the rubber elastic pad and the limit spring and buffer rubber pad on the combined disassembly unit can reduce the impact force caused by the shaking of the stirring motor during use, thereby improving the stability of the stirring motor during use, and improving the stirring effect of the equipment, thereby reducing the limitations of the equipment during use; at the same time, the friction between the stirring motor and the rectangular frame can be increased by the rubber elastic pad, avoiding the phenomenon of dislocation and displacement of the stirring motor during use, which causes the power loss of the stirring motor during use, thereby improving the use effect of the equipment; (5) Pull the limit block upward to move it within the upper limit of the limit square column, so that the limit spring is in a buffer state, so that the limit lock column on the limit block is no longer connected to the limit lock groove, thereby releasing the limit setting of the guide round block and allowing the guide screw to rotate normally; but when the installation of the stirring motor is completed, the limit block is loosened, and the limit lock column is reset by the reset of the limit spring to move it back to the limit lock groove and set the guide round block to the limit position, thereby preventing the stirring motor on the equipment from being dislocated due to non-human factors during use, thereby improving the safety of the equipment during use, avoiding the loss of power source during mixing and causing the mixing failure of the equipment, and reducing the limitations of the equipment during use; (6) When the pressure cross block reciprocates, it will cause the displacement inclined block to reciprocate, thereby driving the second scraper block to reciprocate, making it constantly approach and move away from the driven stirring shaft, so that the second scraper block can reciprocate on the driven stirring rod, and can continuously scrape off the sticky raw materials adhered to the driven stirring rod, avoiding the sticky lumps of raw materials adhering to the driven stirring rod and causing changes in its shape and weight distribution, so that the driven stirring shaft can be balanced when rotating, thereby improving the stirring efficiency of the equipment, avoiding the sticky raw materials adhering to the driven stirring shaft and the driven stirring rod, causing excessive weight and causing damage to the driven stirring shaft and the driven stirring rod when rotating, thereby improving the service life of the equipment and improving the stirring effect and efficiency of the equipment; at the same time, the number of second scraper blocks set corresponds to the driven stirring rod.
