Double-disc integrated seed metering device

Abstract

The invention relates to the technical field of agricultural equipment, and discloses a double-disc integrated seed metering device which comprises a first seed metering mechanism, a second seed metering mechanism, a transmission assembly and a hollow shaft motor, the first seed metering mechanism comprises a first outer shell, a first bottom shell and a first seed suction disc; the second seed metering mechanism comprises a second outer shell, a second bottom shell and a second seed suction disc; the first bottom shell and the second bottom shell are connected, a motor installation position is formed between the first bottom shell and the second bottom shell, the hollow shaft motor is installed at the motor installation position, the first seed suction disc is connected with the output end of the hollow shaft motor, the transmission assembly is installed in a hollow shaft inner ring of the hollow shaft motor, and one end of the transmission assembly is connected with the first seed suction disc. The other end of the transmission assembly is rotatably mounted on the second bottom shell and connected with the second seed suction disc, the first outer shell is connected with the first bottom shell, and the second outer shell is connected with the second bottom shell. The double-disc integrated seed metering device has the advantages that the hollow shaft motor is integrated in the seed-metering device, the size is small, and close planting and sowing can be achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a double-disk integrated seed metering device. Background technique [0002] Sowing is a basic link in vegetable planting, and the quality of sowing will affect the rate of emergence in the future. With the development of modern technology, the technical level of seeders has also been further improved. Especially the present precision hole-sowing seed metering device has the advantages of saving good seeds, no need for thinning, uniform distribution of plants in the field, and being beneficial to the growth of seedlings. At the same time, there are time-saving, labor-saving and production-increasing effects. Therefore, the precision hole sowing seed meter has become an important part of the present vegetable precision operation equipment. In the growing process of the vegetable industry, the pneumatic precision hole sowing seed meter has good working effect, sta...

Problems solved by technology

[0003] In the process of vegetable planting, some vegetable varieties such as coriander, shallot, etc., require high planting density for agronomy, and the distance between rows and holes is about 5*5cm. It is difficult to meet such requirements

For example: China's invention patent application, publication number CN109496504A, discloses a double-disk high-speed pneumatic type sprout seed metering device, which makes it more suitable for sprout seeds through the improvement of the seed suction plate, but the overall volume is larger , cannot meet the needs of dense planting
