The invention provides an air-suction-type seed metering device, and belongs to the technical field of seed metering devices. The air-suction-type seed metering device can control a motor to adjust the rotating speed, thus the sowing plant spacing is controlled, and the sowing area and the sowing amount are mastered. A seed chamber shell of a seed chamber shell assembly and an air suction chambershell of an air suction chamber shell assembly are detachably and fixedly connected through a bottom locking device and a top shell fixing spring, outer teeth are formed in the outer circumferential surface of a seed discharge plate of the air suction chamber shell assembly, a speed-regulating motor drives the seed discharge plate to rotate through a pair of engaged gears, a seed shaving device ofthe seed chamber shell is a six-blade type seed shaving device, a feeding baffle with the regulable height is arranged in a feeding inlet of the seed chamber shell, a seed pushing wheel is arranged in the air suction chamber shell, and the seed pushing wheel makes contact with the seed discharge plate. The air-suction-type seed metering device can achieve high-quality precision sowing and has theadvantages of high single seed rate, even seed down, high speed, consistent plant spacing, low crushing and the like.
Description
technical field [0001] The invention belongs to the technical field of seed metering devices, in particular to an air suction seed metering device. Background technique [0002] As the country's urbanization progresses rapidly, land, water and other natural resources will become more scarce. Therefore, increasing the output per unit area has become an urgent problem that countries need to solve. Precision agriculture has great advantages in this regard. Using information technology platforms, combining big data and mechanical equipment, optimize crop management, increase yield per mu, and finally achieve precise planting of crops. As the largest food crop, the intelligent sowing of corn is particularly important. At present, the seed metering devices of domestic corn planters are all mechanically driven by ground wheels, which cannot meet the requirements of information control. Contents of the invention [0003] Aiming at the problems in the above-mentioned prior art, th...
