Precision seeding device

Abstract

The invention discloses a precision seeding device. Air is injected into a seed storage box so that seeds in the seed storage box are sprayed up in boiling state; inconvenience of seed discharging dueto seed heaping in the seed storage box is prevented; a toothed ring of a suction seeding device is engaged with a half-gear, so that a suction seeding tube can be intermittently rotated to the lowerend of a seed storage tube; since a spindle of the suction seeding tube is provided with a cam, when the suction seeding tube is rotated to the lower end of the seed storage tube, the cam may raise aseed introduction device to move up so as to eject a seed discharge hole to open; seeds are sucked to a suction nozzle along a seed conveying pipe; when a seeding roller is engaged again with the half-gear and is rotated to the lower end, the seeds are sowed under control, so that precision seeding is achieved; the seeding roller may be stopped during suction and sowing, and no suction missing orsowing missing occurs.

Description

technical field [0001] The invention relates to the technical field of sowing, in particular to a precision sowing device. Background technique [0002] The existing sowing methods are mostly sowing, drill and on-demand; the sowing device generally uses a sowing disc to spread the seeds, and generally does not need to organize the land before sowing, which is suitable for large-scale sowing land, while the drill device is set A plurality of sowing strips sow the seeds into the sowing ditch through the sowing strips; while the on-demand sowing device performs on-demand sowing of seeds in the ditch, but the existing sowing device cannot precisely sow the seeds at the same time as the ditch is opened , and the existing pneumatic seeding device also does not stop the movement of the seeding device when the seed is sucked and sowed, so no matter whether it is seed suction or sowing, it will be unstable, resulting in the problems of missing seeding and missing suction.
