The present invention discloses a garlic clove washing device for agricultural product processing. The garlic clove washing device comprises an operation chamber; the right side of the operation chamber is fixedly mounted with a driving motor through a bracket; the operation chamber is provided with a mesh barrel; the output shaft of the driving motor is coaxially fixed with a driving shaft horizontally penetrating the left side wall of the operation chamber; second guide rods horizontally passes limit frames; the left ends of the second guide rods are fixedly provided with rectangular-ambulatory-plane frames. The rotation of the mesh barrel drives inside garlic cloves to rotate to promote full contact between the garlic cloves and washing water; the rotation of the driving shaft realizesrotations of a first driven shaft and a second driven shaft through gear transmissions and drives soft hair brushes to rotate and wash the garlic cloves; the garlic clove washing device promotes flipping of the garlic cloves and is high in washing efficiency; air brush plates conducting reciprocating left and right conduct repeated scraping of the mesh barrel and promote un-obstruction of mesh holes in surfaces of the mesh barrel; and washing water in the washing process can be recycled to effectively save water resources.
