Rolling type precision seeding device for small and medium-sized seeds

Abstract

A rolling type precision seeding device for small and medium-sized seeds comprises a push rod and a seed box; a spindle is mounted at the front end of the push rod; the seed box is rotationally connected onto the push rod with the spindle used as the axis; multiple seeding devices are mounted on the circumference of the seed box; and each seeding device comprises an arc-shaped plate, a seed bin, a seed receiving groove and a duck mouth, the arc-shaped plate is movably connected with the seed box, a seed taking spoon is mounted on the inner arc surface of the arc-shaped plate and is movably connected with the arc-shaped plate, a through hole is formed in the arc-shaped plate, one end, located on the outer arc surface of the arc-shaped plate, of the through hole communicates with the inside of the duck mouth, a fixed piece in the duck mouth is fixedly connected with the arc-shaped plate, the other end of the through hole communicates with a seed outlet in one end of the seed bin, a seed inlet is formed in the side surface of the other end of the seed bin and communicates with one end of the seed receiving groove, the groove opening of the seed receiving groove is opposite to the seed taking spoon, and gaps are formed between the groove opening of the seed receiving groove and the seed taking spoon and between groove opening of the seed receiving groove and the arc-shaped plate. The precision seeding device is high in mechanical seeding accuracy, good in quality and uniform in spacing, seeds, manpower and time can be saved, and the emergence rate can be guaranteed.

Description

technical field [0001] The invention relates to a hand-push rolling seeder, in particular to a rolling precision sower for medium and small seeds. Background technique [0002] Small and medium-sized plant seeds, due to their small size and light weight, when using the traditional structure of the hand-push seeder for sowing, the small and medium-sized seeds in the seed pit around the seed wheel are often swept out by the brush or stuck in the brush , the phenomenon of seed leakage is prone to occur, resulting in missed sowing, resulting in reduced production. Moreover, there are many moving parts in the hand-push seeder with transmission structure, and the electrostatic adsorption phenomenon generated by the body is more obvious, which will adsorb small seeds on the structural parts. The reciprocating movement of the components is easy to crush small seeds, and seeds with defects are not easy to emerge when they are sown into the ground, which will cause a reduction in yiel...

[0002] Small and medium-sized plant seeds, due to their small size and light weight, when using the traditional structure of the hand-push seeder for sowing, the small and medium-sized seeds in the seed pit around the seed wheel are often swept out by the brush or stuck in the brush , the phenomenon of seed leakage is prone to occur, resulting in missed sowing, resulting in reduced production. Moreover, there are many moving parts in the hand-push seeder with transmission structure, and the electrostatic adsorption phenomenon generated by the body is more obvious, which will adsorb small seeds on the structural parts. The reciprocating movement of the components is easy to crush small seeds, and seeds with defects are not easy to emerge when they are sown into the ground, which will cause a reduction in yield. Continuous and uninterrupted sowing to the pre-marked pits on the ridge platform can ensure the integrity of the seeds and high emergence rate. The disadvantage is that the distance between adjacent seedlings is dense and uneven after sowing, and it needs to be separated in the later stage. The seedlings that are too close or redundant are removed, and the seedlings that are too far apart need to be replenished, which not only wastes seeds and land nutrients, but also increases manpower and working hours. Affected by the natural wind, partial sowing occurs, resulting in insufficient sowing depth or bare sowing; in small plots, sloping fields and other areas where large-scale machinery is inconvenient, manual sowing is mostly used. The disadvantage is that the work intensity is high and the sowing efficiency is low.
