Food raw material pretreatment device capable of being automatically adjusted

The invention discloses a food raw material pretreatment device capable of being automatically adjusted, and relates to the technical field of food raw material pretreatment, the food raw material pretreatment device comprises a pretreatment tank, a support frame is fixed on the pretreatment tank, a discharge pipe is mounted at the bottom of the pretreatment tank, and sliding racks are connected to two sides of a central gear II in an engaged manner; a connecting rod is hinged between the connecting sleeve block and the connecting block, and the transmission sleeve is rotationally connected with the connecting sleeve block. A central gear I can rotate forwards and backwards, so that a central gear II drives two sliding racks to move oppositely or oppositely alternately, a guide frame drives push plates to move oppositely or oppositely alternately, food raw materials in the pretreatment tank are effectively promoted to be gathered and dispersed alternately, and the fluidity of the food raw materials is effecti
