Corn seed orientation method and device

Abstract

The invention relates to a corn seed orientation method and device. The method comprises the following steps of: setting an electromagnetic vibration device and a spiral ascending channel at the top of the electromagnetic vibration device; starting the electromagnetic vibration device, and successively pouring corn seeds in a cavity surrounded by the spiral ascending channel, wherein the corn seeds move ahead along the spiral ascending channel in a vibration manner; sieving and removing the corn seeds with small diameters under the action of a sieving gap, and intercepting and sieving the over-thick and over-large corn seeds under the action of an adjusting damper; changing the corn seeds which continuously move ahead from being at a flat pose to be at an upright pose due to the orientation change of the spiral ascending channel; making the corn seeds pass three levels of footsteps jumping downward on the spiral ascending channel under the comprehensive action of the gravity, the vibration inertia force and the friction of the corn seeds, thus arranging the radicles tips of the corn seeds forward consistently; and outputting the corn seeds with the forward radicles tips and vibrating advancement, wherein the upright pose of the corn seeds is gradually changed to be in an almost horizontal pose with an angle of inclination due to the orientation change of the spiral ascending channel. The corn seed orientation method and device can be widely applied to following treatment and orientated seeding of agricultural seeds.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a corn seed orientation method and an orientation device. Background technique [0002] Corn is an important food crop in my country. The directional planting method of corn can not only effectively control the directionality of the growth and arrangement of the leaves of corn plants, but also improve the disorder of the extension of corn leaves, thereby enhancing the photosynthetic ability of corn leaves per unit area to increase yield. ; Corn realizes mechanized directional sowing, and its key technology is to realize the directional arrangement of corn seeds, but at present, there is no special directional sowing equipment for mechanized corn directional sowing, so that mechanized and automatic corn directional sowing cannot be carried out; in the patent document No. 200810146659.2 discloses a corn directional sowing method, directional seed block manufacturing equipment, and a sowing ...

[0002] Corn is an important food crop in my country. The directional planting method of corn can not only effectively control the directionality of the growth and arrangement of the leaves of corn plants, but also improve the disorder of the extension of corn leaves, thereby enhancing the photosynthetic ability of corn leaves per unit area to increase yield. ; Corn realizes mechanized directional sowing, and its key technology is to realize the directional arrangement of corn seeds, but at present, there is no special directional sowing equipment for mechanized corn directional sowing, so that mechanized and automatic corn directional sowing cannot be carried out; in the patent document No. 200810146659.2 discloses a corn directional sowing method, directional seed block manufacturing equipment, and a sowing block device. The method of the invention is to remove the seed strips or use Cut the seed strips with the shovel knife. Although the seed strips cut by the shovel can maintain the order of the biological characteristics of corn to a certain extent, the damage to the corn kernels is serious, and the corn seeds have not been pre-processed, so it is difficult to adapt for direct sowing
