The invention belongs to the technical field of agricultural processing, particularly relates to a mashing device for agricultural processing, and aims to solve the problems that a conventional mashing device for agricultural processing is generally simple in structural design, and materials are not crushed, so that when mashing treatment is directly performed, the processing efficiency is low, and the processing period is long. The invention provides the following scheme that the mashing device comprises a fixed frame, wherein a feeding hopper is fixedly mounted on one side close to the top end, of the fixed frame, and a driving mechanism is mounted on one side of the feeding hopper. In the vertical movement process of a clamping ring, an L-shaped vertical rod can be used for driving a mashing block to do reciprocating motion, and therefore, mashing treatment on materials is achieved through cooperation with a mashing basin. Through the arrangement of a refrigerator, the mashing basincan be subjected to temperature lowering and cooling treatment, so that bottom temperature can be utilized to cool materials to prevent the condition that the materials are overheated, and nutrient substances of the materials are influenced; and low temperature can be utilized to harder the texture of the materials, so that the mashing effect is conveniently improved.
