The invention relates to a longan pitting machine. The longan pitting machine comprises a rack, a pitting assembly and a laying-off assembly, wherein the pitting assembly is positioned in front of therack, and the laying-off assembly is positioned at the upper rear part of the rack; the pitting assembly comprises a sliding block, a linear guide rail, a linear guide rail sliding block, a roller, aplurality of arc-shaped fruit guiding blocks, a plurality of core pushing rubber parts and a plurality of core pushing rods; the linear guide rail is vertically installed on the rack, the linear guide rail sliding block is installed on the linear guide rail, the linear guide rail sliding block is connected with a horizontally arranged sliding block, and a plurality of push rods are arranged on the sliding block in a vertical distribution mode; the outer wall of the roller is axially provided with the plurality of rows of core pushing rubber parts distributed at equal intervals, and provided with the plurality of core pushing rubber parts in the circumferential direction, and the arc-shaped fruit guiding blocks are connected with two adjacent core pushing rubber parts which are circumferentially distributed; the plurality of push rods are positioned above the plurality of axially distributed core pushing rubber parts. The longan pitting machine is used for pitting shell-removed core-containing longan fruit, loses less juice, the production efficiency is high, and the quality is stable. The longan pitting machine belongs to the technical field of food machinery manufacturing.
