Seed metering device of cuttage type ligusticum wallichii seed planter and control method of seed metering device

Abstract

The invention relates to a seed metering device of a cutting type ligusticum wallichii and poria cocos seed planter and a control method thereof, the seed metering device comprises two conveying belts which are arranged in parallel at an interval, ligusticum wallichii and poria cocos seeds are placed at the interval between the two conveying belts, and the two conveying belts clamp and lift section discs of the ligusticum wallichii and poria cocos seeds from two sides; the seed throwing box is arranged at the rear end of the conveying belt and is in a V-shaped groove shape, and a throwing gap is formed in the groove bottom of the seed throwing box; ligusticum wallichii seeds fall between the intervals of the conveying belts through throwing gaps of the seed throwing boxes. The conveying belt moves ligusticum wallichii seeds from the rear end to the front end; a control system and a seed guide component are further arranged, and arrangement of ligusticum wallichii seeds is achieved. The device has the beneficial effects that seeds are convenient to put, the poria cocos seeds can be automatically in a vertical state, seed arrangement can be realized, and the automation degree is high.

Description

technical field [0001] The invention relates to the technical field of medicinal herb planting equipment, in particular to a seeding device and a control method of a cuttage-type chuanxiongling seed planter. Background technique [0002] Ligusticum chuanxiong is an authentic medicinal material in Sichuan, which belongs to the rhizome class of traditional Chinese medicinal materials. It has a wide planting area and high yield. Ligusticum chuanxiong adopts vegetative propagation. At present, the cultivation of Ligusticum chuanxiong is almost all artificial planting. The stem knots with bud openings on the stalks are cut to 30-50mm as Ling seeds for planting. Lingzhong has a node plate in the middle, and there is a bud opening on the node plate. A certain length of stem is reserved at both ends. The length of the stem at the upper end of the bud opening is slightly shorter than the length of the other end. The Ling seed is planted with the bud opening facing upward. The long e...

AI Technical Summary

Problems solved by technology

Artificial planting of Ling seeds is inefficient and labor-intensive, which increases the planting cost of growers

[0003] Ling seeds have a special shape and are planted with buds facing upwards. It is necessary to arrange the seeds in an orderly and directional manner to meet the needs of mechanized sowing. At present, no seed metering device and seed delivery device suitable for planting Ling seeds have been found. The existing The seeding technology is suitable for common corn, peanuts and other seeds with relatively regular shapes. This kind of seeding technology is used for seeding of Chuanxiong Ling seeds. It is difficult to achieve orderly and directional seeding and transportation of Ling seeds, resulting in The problems of missed sowing, re-seeding and damage to Ling seeds affect the yield and quality of Rhizoma Chuanxiong, and do not meet the agronomic requirements for planting Rhizoma Chuanxiong.
