The invention discloses a tractor suspension type thinning device. The tractor suspension type thinning device comprises a machine frame, a supporting adjusting wheel and thinning units; each thinning unit comprises a four-rod floating mechanism, a mounting frame, a gearbox, a horizontal rotating cutter head, a thinning shovel, a driving land wheel and a driving wheel shaft; the mounting frames are fixedly connected with the four-rod floating mechanisms, and the four-rod floating mechanisms are connected with the machine frame; gearbox mounting seats, horizontal bearing seats and vertical bearing seats are correspondingly mounted at corresponding positions of the mounting frames; the gearboxes are mounted on the gearbox mounting seats; first chain wheels are mounted on input shafts of the gearboxes; connecting shaft sleeves are mounted on output shafts of the gearboxes, and horizontal rotating cutter heads are mounted on the horizontal bearing seats through mounting shafts on the horizontal rotating cutter heads and are connected with the connecting shaft sleeves; the thinning shovels are mounted on the horizontal rotating cutter heads in pairs; the driving wheel shafts are mounted on the vertical bearing seats; the driving land wheels are fixedly mounted at two ends of the driving wheel shafts; second chain wheels are mounted on the driving wheel shafts; the first chain wheels are connected with the second chain wheels through chains; and the power of the horizontal rotating cutter heads is provided by the driving land wheels.
Description
technical field [0001] The invention belongs to the field of crop thinning, in particular to a tractor-mounted thinning device. Background technique [0002] When some crops such as miscellaneous grains and vegetables are planted, in order to ensure the emergence rate and improve the sowing efficiency, dense sowing will be adopted for intensive sowing. Due to agronomic requirements, thinning and planting should be carried out at the seedling stage after crop emergence. Thinning and planting are mostly done manually, which is labor-intensive and inefficient, and the spacing of seedlings varies greatly. Contents of the invention [0003] In order to solve the technical problems existing in the prior art, the present invention provides a tractor-hung type seedling thinning device, which adopts the tractor-hung type operation mode and can realize equidistant uniform thinning. The tractor-mounted seedling thinning device of the present invention can realize multi-row operation...
