A cutting and cutting threshing device suitable for treating a fruit having at least one portion to be removed. The cutting and threshing threshing device comprises a base frame, two nip rollers spaced apart from each other and rotatably disposed on the base frame, and a power source. The nip rolls define a gap that is smaller than the fruit and that is accessible for the at least one portion to be removed. The outer peripheral surface of each nip roller is formed with at least one spiral blade, and the power source can drive the nip rollers to rotate in different directions along their own axes. The spiral knives can be used to cut the at least one portion to be removed to facilitate the threshing operation. Since the present invention only needs to provide the nip rolls and does not need to provide a conventional conveying screw, the configuration is simple, the disassembly and assembly is easy, and the maintenance cost can be reduced.一種裁枝切鬚脫粒裝置，適用於處理一具有至少一待拔除部位的果實。該裁枝切鬚脫粒裝置包含一基架、二上下相間隔且可旋轉地設置於該基架上的夾輥，及一動力源。該等夾輥界定出一小於該果實且可供該至少一待拔除部位伸入的縫隙。每一夾輥的外周面形成有至少一螺旋刀紋，該動力源可帶動該等夾輥沿自身軸線分別朝不同方向旋轉。該等螺旋刀紋可用來切斷該至少一待拔除部位，以利於脫粒作業。由於本新型僅需設置該等夾輥且不需設置習知的輸送螺形件，因此配置簡單且拆裝容易，並可降低維修成本。
