Precision drill for easy exchange of seeding devices

Abstract

The invention discloses a precision dibbler with an easily-replaced planting mechanism. The precision dibbler comprises planting fixed duck beaks, planting movable duck beaks, a planting ring, planting boxes and beak fixing hinges, wherein a plurality of mounting holes are arranged on the planting ring, and the planting fixed duck beaks, the planting boxes, the beak fixing hinges and the planting fixed duck beaks have several groups and are arranged on the outer surface of the planting ring through the planting ring; the planting boxes are arranged on the inner surface of the planting ring, the planting fixed duck beaks and the planting movable duck beaks coordinately form a seed outlet, and the planting boxes are used for storing seeds; the beak fixing hinges are connected with the planting ring by using bolts; and the planting movable duck beaks are connected with the beak fixing hinges through a spring and a manner of hinged connection by using the lever principle. The dibbler has a reasonable structure and design, the planting mechanism and the planting ring are detachably connected and can be mounted and dismounted freely, the replacement and maintenance are convenient, labor-saving and time-saving, and simultaneously the planting reliability of the duck beaks of the dibbler is improved; and in addition, based on the precision dibbler, plant distance can be conveniently changed according to site conditions, and the purpose of saving cost is achieved.

Description

technical field [0001] The invention relates to a precision hole seeder which is easy to replace a seeding device, and belongs to the technical field of agricultural machinery. Background technique [0002] At present, most of the hole sowers of the seeder are wheeled structures, and the position distribution of the seeds in the soil after seeding is directly related to the shape and structure of the seeding duckbill. But at present, the seeding device of the hole sower, because of its structural design, causes the hinges to be fixed on the hole sower, and they have been connected with the seeding ring into an inseparable whole, and the seeding device of the hole sower is a vulnerable part. Once the seeding mouth is deformed, damaged, etc., it is very difficult to repair it, and it takes a lot of time and cost to repair, the maintenance is cumbersome, and the reliability is not strong. Because of this design structure, the plant distance of the hole seeder is fixed and infle...

Problems solved by technology

But at present, the seeding device of the hole sower, because of its structural design, causes the hinges to be fixed on the hole sower, and they have been connected with the seeding ring into an inseparable whole, and the seeding device of the hole sower is a vulnerable part. Once the seeding mouth is deformed, damaged, etc., it is very difficult to repair it, and it takes a lot of time and cost to repair, the maintenance is cumbersome, and the reliability is not strong. Because of this design structure, the plant distance of the hole seeder is fixed and inflexible. Not widely applicable
