Problems solved by technology

Pneumatic seed metering device has strong adaptability to seeds and light damage, but its structure is complicated, and its cost and technical requirements are high
The mechanical precision seed metering device is simple in structure, easy to manufacture and low in price, but it often causes damage to the seeds during use, which not only wastes the seeds, but also directly affects the emergence rate in the field and leads to a decrease in yield

Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing:

[0016] Inclined disk disc seeding device for corn seeder, including seed box 1, seeding spoon 2, seeding disc 3, housing 4, fixed bracket 5, seeding hole 6, partition 7, drive shaft 8 and guide Seed tube9.

[0017] as attached figure 1 As shown, wherein the drive shaft 8 transmits power to the sorting disc 3 through the bevel gear, and the sorting disc 3 rotates thereupon; the seeds located in the seed filling area at the bottom of the seed box 1 slide into the seed box 2 and the dividing plate 7. In the seed holding space formed by oblique crossing, the sorting disc 3 rotates, and the seeds are lifted up by the sorting spoon 2; The stable seeds fall back to the seed filling area at the bottom of the seed box 1 under the action of gravity; the stable seeds in the described sorting spoon 2 continue to move upwards with the rotation of the sorting disc 3 until the seed disc...

Abstract

The invention belongs to the technical field of seed metering devices, and particularly relates to an inclined disk-type seed metering device for a corn planter. The inclined disk-type seed metering device comprises a seed box (1), a metering scoop (2), a metering disk (3), a shell (4), a fixing support (5), a feed outlet (6), a partition plate (7), a driving shaft (8) and a seed guide pipe (9). The driving shaft (8) transmits power to the metering disk (3) through a bevel gear, the metering disk (3) rotates along with the driving shaft (8), seeds positioned in a lower seed filling area of theseed box (1) slide into a seed holding space formed by obliquely crossing the metering scoop (2) and the partition plate (7), the metering disk (3) rotatably moves, the seeds are lifted upwards by the metering scoop (2), and unstable seeds lifted by the metering scoop (2) fall back to the lower seed filling area of the seed box (1) under the action of gravity when the metering scoop (2) lifts theseeds to rise to a certain height. The device is simple in structure, small and flexible, seed damage rate caused by the seed metering device is reduced, and field seedling emergence rate is increased.

Description

technical field [0001] The invention belongs to the technical field of seed metering devices, and in particular relates to an inclined disc seed metering device for a corn planter. Background technique [0002] Corn is China's largest food crop, and its main production area is located in the third largest corn belt in the world - China's Songliao Plain Corn Belt. The total planting area of ​​corn is about 1249.35 square kilometers, also known as maize, corn, corn, and cob. Cantonese is called corn, and Hokkien is called fanmai. It is an annual grass herb, an important food crop and an important source of feed, and it is also the food crop with the highest total output in the world. [0003] Due to the high economic value of corn, it is planted as an important economic crop in rural areas. Now that corn is the main source of biodiesel, the price of corn has risen again. Among the main economic crops in rural areas, the price of corn is Planting already occupies a considera...
