Precision seeding device for particle seeds

Abstract

The invention provides a precision seeding device for particle seeds. The precision seeding device comprises a rack, a first press wheel, a second press wheel, electric walking wheels, a third resistance switch, a storage battery, a switching power supply, a fan, a first direction lever, a second direction lever and a sowing assembly are arranged on the rack, the storage battery is electrically connected with the switching power supply, and an electric walking wheel is electrically connected with the switching power supply. The third resistance switch is used for controlling on and off of the electric walking wheels, a first resistance switch is arranged on the first direction lever, is arranged on a circuit for connecting the switching power supply and the fan and controls on and off of the fan, and the fan communicates with the sowing assembly through an air suction pipe. Current passing through the fan can be adjusted through the first resistance switch, so that the seed discharging speed in the sowing assembly is changed, and the electric walking wheel can be adjusted to the required running speed by turning on the third resistance switch. According to the precision seeding device for the particle seeds, precise sowing can be achieved by changing the seed discharging speed and the walking speed of the electric walking wheels, and the sowing efficiency can be improved.

Description

technical field [0001] The invention belongs to the field of seeding machines, and in particular relates to a precision seeding device for particulate seeds. Background technique [0002] With the development of agricultural science and technology, mechanical equipment has been widely used in agriculture. In many large farms, the seeder has been replaced by a mechanical seeder. However, due to the special geography of our country, in the central and western regions More land, less flat land, and less land per capita, it is difficult to meet the sowing conditions of large seeders. In many areas, most of the plant seeds are small, and many of them are particulate seeds. There are problems of uneven seeding, low efficiency, and time-consuming and labor-intensive problems during artificial seeding. [0003] Chinese utility model patent CN211297648U discloses a rolling seeder that can be automatically avoided by reversing, including the seeder, including a roller, a rotating sha...

Problems solved by technology

With this device, the seeder can sow seeds when it is rotating forward, and when it is reversed, it can automatically avoid the lever to make the seeder idling, avoiding damage to the machine caused by reverse rotation. The processing process is simple and the processing cost is low, and it is more suitable for farmers to target corn. Sowing, although the sower can achieve precision sowing, but the distance between the duckbills remains unchanged, so the distance between the seeds cannot be adjusted, and the opening of the duckbills may not change due to the different sizes of the seeds during sowing. In the case of multiple sowing, and because the soil is often wet during sowing, it is easy to block the duckbill, and then there will be missed sowing, resulting in low sowing efficiency
