Description

Technical Field

[0001] The utility model relates to the technical field of multi-channel seed metering devices, in particular to a material discharging control mechanism of a multi-channel seed metering device. Background Art

[0002] A multi-channel seed meter can simultaneously supply seed to multiple rows, completing the sowing task for multiple rows in a single operation. This significantly reduces the number of times the seeder must make repeated field trips, significantly improving overall sowing efficiency compared to a single-channel seed meter. For large farmland, a multi-channel seed meter can be paired with large seeding machinery. It fully utilizes the seeder's operating width, covering a larger area without increasing operating time. This is crucial for meeting the demand for large-scale, rapid sowing in modern agricultural production.

[0003] After searching, the prior art, Chinese patent application number: CN202110406114.6, discloses a discharge control mechanism and a seed meter for a multi-channel seed meter. The invention: includes a plurality of arc-shaped plates arranged in a linear array, and also includes a control assembly; the arc-shaped plates can slide along a first arc-shaped trajectory relative to the frame of the multi-channel seed meter; the arc-shaped plates have a control portion; the control assembly includes a drive shaft, on which a plurality of control rods are mounted, the control rods are arranged in a linear array, and the array spacing of the control rods is greater than the array spacing of the arc-shaped plates; when the drive shaft acts on the control portion, it can drive the arc-shaped plates to move; the drive shaft is driven by the drive assembly to translate along a second arc-shaped trajectory; the central axis of the first arc-shaped trajectory, the central axis of the second arc-shaped trajectory and the central axis of the arc-shaped plate itself coincide with each other; the drive shaft can move axially so that the control rod acts on the control portion or disengages from the control portion. By manipulating the drive shaft to translate, the invention can adjust the number of pairs of control rods and the control portion, thereby realizing control of the seed discharge channel of the multi-channel seed meter, and is easy to use.

[0004] However, the device still has the following defects:

[0005] When controlling seed discharge, existing discharge control mechanisms are prone to seed blockage near the discharge port. Due to the physical properties of seeds (such as irregular shape and rough surface) and factors such as humidity, seeds may accumulate at the discharge port and block the channel, resulting in large-scale missed seeding and reduced efficiency.
