Technical Field

[0001] The utility model relates to the technical field of kudzu root processing, in particular to a kudzu root crushing and screening device. Background Art

[0002] Pueraria root has multiple pharmacological effects such as antipyretic, coronary artery dilation, anti-myocardial ischemia, improvement of cardiac function, improvement of cerebral circulation, lowering blood pressure, inhibition of platelet aggregation, and lowering blood sugar. During the production and processing process, it is usually produced and packaged in the form of pueraria root powder. Therefore, after the picked pueraria root is cleaned, it is usually necessary to use a crushing and screening device to crush and screen the pueraria root for subsequent processing steps. As shown in the pueraria root crushing and screening mechanism disclosed on the China Patent Network (public announcement number CN220328885U), this type of device, when performing the crushing and screening process on the pueraria root, drives the first crushing blade to rotate based on the first crushing shaft and drives the second crushing blade to rotate based on the second crushing shaft, thereby realizing secondary crushing of the pueraria root, and then the sieve plate screens the pueraria root that has been crushed to complete its crushing and screening process.

[0003] However, the aforementioned patents and the existing kudzu root crushing and screening mechanisms used in the market still have some shortcomings: the existing method of using a crushing knife to directly rotate and crush the kudzu root has poor stability in the crushing of the kudzu root, and is prone to incomplete crushing and direct material falling, resulting in a relatively low efficiency in the crushing of the kudzu root. A comprehensive crushing process requires recycling of the material. To this end, those skilled in the art have provided a kudzu root crushing and screening device to address the problems raised in the above-mentioned background technology. Utility Model Content
