Description

technical field [0001] The invention relates to an agricultural machine part, in particular to an electric adjustable air suction precision metering device for sowing crops. Background technique [0002] The structure of the existing electric air-suction precision metering device is composed of a sowing body, an electric suction fan and a generator. The generator is driven by a diesel engine on a tractor. , resulting in a reduction in the voltage of the generator, which reduces the speed of the electric suction fan directly driven by the generator, and then causes the negative pressure generated by the sowing body to be insufficient, resulting in a low seeding rate, with the highest seeding rate only reaching 85%. [0003] In addition, the electric suction fan used in the existing electric air-suction precision metering device is a DC carbon brush motor, which cannot be adjusted in speed, and the negative pressure of the sowing body cannot be adjusted according to the size a...
