Row-spacing-adjustable type agricultural seeder capable of synchronously sowing in multiple rows

Abstract

The invention discloses a row-spacing-adjustable type agricultural seeder capable of synchronously sowing in multiple rows. According to the row-spacing-adjustable type agricultural seeder capable ofsynchronously sowing in the multiple rows, when space between two adjacent seed falling tubes is adjusted, the lower end discharging end of a discharging assembly is synchronously adjusted with the seed falling tubes, so that the adjustment of row spacing can be realized conveniently; and the lower end discharging end of the discharging assembly and the seed falling tubes are synchronously adjusted to ensure that the lower end discharging end and the seed falling tubes can be vertically and coaxially arranged all the time, so that the occurring of the uneven or blocking phenomenon when seeds fall is avoided; through the combined use of a fixed sieve plate, a groove, a sliding sieve plate and a fixing bolt, the discharging speed can be adjusted and controlled, and thus the sowing density iscontrolled, so that the agricultural seeder is suitable for sowing with different seed density; and by installing a vibration motor at the bottom end of the fixed sieve plate, the fixed sieve plate and the sliding sieve plate can vibrate, and thus the seeds are enabled to fall off from gaps between the fixed sieve plate and the sliding sieve plate.

Description

technical field [0001] The invention relates to the technical field of agricultural seeders, in particular to a multi-row synchronous row-spacing adjustable agricultural seeder. Background technique [0002] Seeder is a planting machine that takes crop seeds as the sowing object. The seeder used for a certain type or a certain crop is often named after the type of crop, such as grain drill, corn hole seeder, cotton seeder, pasture spreader, etc. [0003] At present, it is difficult for the existing agricultural seeders on the market to control the density of sowing, so that it is difficult to make the agricultural seeder suitable for sowing seeds with different densities, and it is difficult to adjust the distance between the seed drop tubes, so it is difficult to realize the difference between different row spacings. of sowing. Therefore, those skilled in the art have provided an agricultural seeder capable of multi-row synchronization and adjustable row spacing, in order...
