Seedling-supporting seedling planting device for dry land vegetable transplanter

Abstract

The invention discloses a seedling-supporting seedling planting device for a dry land vegetable transplanter. The inner wall of the duckbilled part of a duckbilled seedling planting mechanism is likely to carry soil, the seedling planting effect is unsatisfactory, and the duckbilled part is likely to hit stones and get damaged. A seedling guiding square tube is fixed to the rear portion of a furrow opener of the seedling-supporting seedling planting device. A front baffle is hinged to a rack mechanism. The rear end of a front baffle square beam is fixed to the front baffle, and the middle of the front baffle square beam is connected with a pressing wheel sleeve through a tension spring. A pressing wheel short pin is fixed to a boss of a rotor and sleeved with the pressing wheel sleeve. The top end of a seedling pushing plate square beam is hinged to the pressing wheel short pin, and the bottom end of the seedling pushing plate square beam is fixed to a seedling pushing plate. The seedling pushing plate is hinged to the bottom of the front baffle. One side of a U-shaped round tube is hinged to the furrow opener and fixed to the rear end of a lever pin shaft square beam. The front end of the lever pin shaft square beam and a U-shaped groove of the front baffle square beam form a sliding pair. The top of a rear baffle and the other side of the U-shaped round tube form a rotating pair and are connected through a torsion spring. A seedling pushing mechanism of the seedling-supporting seedling planting device pushes pot seedlings into furrows at the zero speed, and thus the planting effect is good; the device is high in strength and capable of adapting to various soil conditions.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a transplanting machine, in particular to a seedling-supporting seedling planting device for a dry-land vegetable transplanting machine. Background technique [0002] At present, most dryland vegetable transplanting machines in my country use duckbill seedling planting mechanism, but this kind of seedling planting mechanism is prone to clay and cannot cope with sticky soil. For example, in the process of planting rapeseed, the inner wall of the duckbill is easy to carry soil, resulting in unsatisfactory planting effect. On the other hand, the duckbill type seedling planting mechanism has a complex structure, and the whole mechanism is not easy to produce and process, and the cost is high. And in the case of some poor soil conditions, the duckbill is easy to touch the stones inside the soil and cause damage, which causes unnecessary troubles for farmers and makes the effect of ...

Problems solved by technology

[0002] At present, most dryland vegetable transplanting machines in my country use duckbill seedling planting mechanism, but this kind of seedling planting mechanism is prone to clay and cannot cope with sticky soil. For example, in the process of planting rapeseed, the inner wall of the duckbill is easy to carry soil, resulting in unsatisfactory planting effect

On the other hand, the structure of the duckbill type seedling planting mechanism is complex, the whole mechanism is not easy to produce and process, and the cost is high.

And in some cases of poor soil conditions, the duckbill is easy to touch the stones inside the soil and cause damage, which causes unnecessary troubles for farmers and makes the soil covering effect unsatisfactory
