Problems solved by technology
Among them, the grid plate is driven by the ground wheel, and the sowing length is changed by manually adjusting the diameter of the transmission belt. Every time the length of the plot is changed, the mechanical structure needs to be manually adjusted, which is time-consuming and laborious.
In addition, belt aging and slippage will also affect the sowing accuracy
When sowing in multiple rows, the rotation speed of the centrifugal distributor is controlled by a speed proportional to the speed of the ground wheel, which cannot take into account the change in the speed requirements of different seeds.

The invention belongs to the technical field of an agricultural seed discharging device and relates to a seed discharging device for a subregion seeder. The seed discharging device comprises a lifting rod (1), a seed storage device (2), a seed feeding device (3), a seed transportation device (4), a support fixing device (5) and an electromagnetic device (6). The seed discharging device is characterized in that the lower end of the seed storage device (2) is provided with the seed feeding device (3) and the seed transportation device (4), one side of the seed storage device (2) is provided with the lifting rod (1) and the electromagnetic device (6) connected to the lifting rod (1) arranged on the support fixing device (5), the seed feeding device (3) is tapered, the small end opening of the seed feeding device (3) is connected to the lower end of the seed storage device (2) and the large end opening of the seed feeding device (3) is connected to the seed transportation device (4). The seed discharging device has a simple structure and good practicality, ensures small angle errors of a seed discharging grid disc rotating a round at different rotation rates and has a high control precision and good line space consistency.
Description
technical field [0001] The invention belongs to the technical field of seeding equipment for agricultural equipment, and in particular relates to a seeding device for a small-area seeder. Background technique [0002] In the whole process of crop breeding experiment area management from sowing to harvesting, there are common problems such as cumbersome working procedures, many links of manual participation, high labor intensity, labor-intensive and time-consuming, and easy to cause human errors. The realization of mechanized management of crop breeding test areas and computerization of data acquisition, processing, and evaluation can not only ensure the accuracy and scientificity of breeding experiments, but also help reduce test costs and improve work efficiency in crop breeding test areas. [0003] Manual seeding tends to cause large experimental errors, while mechanical seeding helps to reduce experimental errors. Among them, the grid plate is driven by the ground wheel,...
