A side vertical spoon type directional and fixed distance output device for corn seeds

Abstract

The invention relates to a corn seed edge-on scoop orientation fixed-distance output apparatus. The corn seed edge-on scoop orientation fixed-distance output apparatus comprises a fixed rack, a whole-column edge-on mechanism and an orienteering and distance fixing mechanism, wherein the whole-column edge-on mechanism comprises a circular electromagnetic vibrator and a hopper, the orienteering and distance fixing mechanism comprises an edge-on feeding unit, an orienteering and distance fixing unit and an edge-on output unit. The whole-column edge-on mechanism utilizes a sorting track to sort corn seeds and utilizes an edge-on attitude change track to change an edge-on attitude of the corn seeds at a flat-on attitude; and the orienteering and distance fixing mechanism utilizes the mass center eccentricity characteristic of the corn seeds to enable the corn seeds at the edge-on attitude to successively enter a scoop-type orienteering and fixed-distance hole in a state that a sharp end of the corn seed faces upwards through the combined action of frictional force, exciting force and the like, then the corn seeds are brought to an outlet of the orienteering and distance fixing unit and slide out of the scoop-type orienteering and fixed-distance hole in a state that the sharp end of the seed faces forwards, so that the corn at the edge-on attitude can be simultaneously orientated and distanced, the corn seeds are finally outputted in an edge-on state that the sharp end of a root consistently faces forwards, and the distance of two adjacent seeds is consistent.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a corn seed side vertical spoon type directional and fixed-distance output device. Background technique [0002] Corn is an important food crop in my country. Directional sowing of corn can control the orientation of corn seeds into the soil, make the direction of corn plant leaf expansion consistent with the direction of ear growth, and effectively improve the light and ventilation of crops in the field. On this basis, it can reasonably improve planting. Density, in order to achieve the purpose of increasing the yield of corn, and improve the level of mechanized harvesting. [0003] The directional and fixed distance output of corn seeds is one of the key technologies to realize the directional sowing of mechanized corn, but there are few related researches so far. Chinese patent CN102893723A discloses a corn seed orientation method and an orientation device. The ...

Problems solved by technology

Chinese patent CN102893723A discloses a corn seed orientation method and an orientation device. The device uses the three-level steps of the orientation chute to orient the corn seeds so that the radicle tips of the corn seeds are aligned forward, and finally lie flat in a nearly horizontal shape. Attitude output, but the structure of the device is complex, the success rate of orientation is low, and it is impossible to operate the corn seeds at a fixed distance; Chinese patent CN102918963A discloses a corn seed directional separation and fixed distance seeding device and its operation method. The electromagnetic vibrating device orients the radicle tip of the corn seeds forward and outputs them in a flat posture, and then the separation and spacing device separates and distances the corn seeds in the flat posture, but the structure of the device is complex, and the corn seeds Orientation and distance determination are carried out separately. When the distance operation is performed on corn seeds that have been oriented and lie flat, it is easy to destroy the original orientation results, that is, the direction of the radicle tip is no longer aligned forward.
