Abstract

The utility model relates to the technical field of cyperus esculentus planting, in particular to a soil crushing device for cyperus esculentus planting, which comprises a base, a vibration component, a sweeping component, a conveying component and a loading component, and is provided with a limiting shell, a banister brush, a conveying belt, a mounting block, a mounting shaft, a rotating seat and a loading plate. According to the device, the anti-falling shell and the rotating shaft can be driven to vibrate synchronously through the vibratable limiting shell, the multiple pairs of mounting blocks are driven to move through the movable conveying belt, then the carrying plate drives cyperus esculentus grains to move while vibrating, meanwhile, the carrying plate can rotate randomly through cooperation of the rotating base and the mounting shaft, and therefore the cyperus esculentus grains can be prevented from falling off. According to the cyperus esculentus seed screening device, the cyperus esculentus seeds are vibrated to be broken rapidly, then the cyperus esculentus seeds are swept through the banister brush, the soil and the rhizomes on the cyperus esculentus seeds can be thoroughly removed, and therefore the cyperus esculentus seed screening device has the better screening effect and the higher screening efficiency.
