Abstract

The invention discloses a seeding rate adjusting device for a seed metering device. The seeding rate adjusting device comprises a spindle, an outer perforated wheel, an inner perforated wheel, a rotating drive mechanism and a locking mechanism, and the outer perforated wheel, the inner perforated wheel, the rotating drive mechanism and the locking mechanism are rotatably mounted on the spindle. The outer periphery of the outer perforated wheel is provided with through holes, the outer periphery of the inner perforated wheel is provided with grooves corresponding to the through holes, and the inner perforated wheel sleeves the outer perforated wheel rotatably, slidably and internally. The rotating drive mechanism is fixedly connected with the inner perforated wheel, and an output end of the locking mechanism slidably presses the inner perforated wheel to realize fixed connection between the inner perforated wheel and the outer perforated wheel. The inner perforated wheel is capable of rotating relative to the outer perforated wheel to realize a staggered, intersected or overlapped positional relation between the grooves and the through holes, and accordingly size adjustment of seed holding spaces between the through holes and the grooves is realized. The seeding rate adjusting device has the advantages of electrical regulation control, convenience in operation, high seeding efficiency, safety and reliability.

Description

technical field [0001] The invention belongs to the field of agricultural seeding equipment, and relates to a regulating device, in particular to a sowing rate regulating device of a seed metering device. Background technique [0002] The seed meter is one of the important parts of the planter. Its function is to guide the seeds in the seed box of the planter into a uniform seed flow or a single seed to control the seeding rate and achieve uniform sowing. Seed metering device is of a great variety, and at present, the combination hole wheel type seed metering device is the main seed metering device of existing rice direct seeding. The existing combined hole seed metering device can sow various seeds of different sizes to adjust the sowing amount by adjusting the positioning mechanism, but this adjustment method is all manually performed. Every time the positioning mechanism needs to be adjusted, it needs to Stopping the work at hand increases the labor intensity of farmers,...
