The invention relates to a multi-spindle mechanized machine for harvesting caragana korshinskii seeds. The multi-spindle caragana korshinskii seed collecting and harvesting machine comprises a rack, a plurality of spindles rotatably supported on the rack, collection devices fixed to the spindles, a drive mechanism for driving the spindle to rotate and fruit pod and seed conveying devices. The spindles located on the left half portion of the rack is symmetrical to the spindle located on the right half portion of the rack, the collection devices are the same as the spindles in number, the conveying devices are arranged in a left-right mode, and the collection devices are in left-right symmetry to the conveying devices. The power is from a traction machine or an independent engine, the walking mode can be either a traction mode or a self-walking mode, the machine can ride on a caragana korshinskii plant when working, collecting and harvesting of one line of caragana korshinskii seeds/fruit pods can be completed one time at a minimum, and thus collecting and harvesting efficiency can be doubled; meanwhile, mechanized collecting and harvesting work of seeds of high-plant type caragana korshinskii such as white caragana korshinskii can be further conducted, and the problems that the collecting and harvesting link of caragana korshinskii seeds is low in efficiency and high in cost are solved.
