Abstract

The utility model relates to a seed taking device for mechanical hill seeders, comprising a seed box, a swing wheel and a swing rod, wherein a capsule seed pit is arranged on the swing wheel; and the front end of the swing rod is provided with a roller wheel. The seed taking device is characterized in that: a fixed disc is arranged in the hill seeder; a curve track is arranged below the fixed disc; a retainer ring is arranged above the fixed disc; the roller wheel and the curve track are adapted to each other; when the roller wheel enters the curve track, the capsule seed pit is exposed outside the seed box; the back end of the swing rod is provided with a return inclined plane; the return inclined plane and the retainer ring are adapted to each other; and when the return inclined plane is in contact with the retainer ring, the capsule seed pit enters the seed box. The seed taking device does not need to be provided with a reset spring, can finish the swing of the swing rod; moreover, the device is long in the life span of working components for taking seeds, high in working reliability and strong in adaptability.

Description

A kind of seed taking device of mechanical type dibbler

One, technical field

The utility model relates to the crop hole sowing device, is specifically related to a kind of seed taking device of mechanical type dibbler.

Two, background technology

Because the mechanical type dibbler is lower than air-sucking type seeder cost, and realizes easily precision drilling having obtained significant progress in recent years.The technological difficulties of mechanical type dibbler are kind of the problems of getting, and therefore seed taking device rational in infrastructure is the key that improves the dibbler performance.At present, more advanced dibbler can only be got a seed, reaches the purpose of precision drilling.The seed taking device of this dibbler is made up of escapement, fork and fan-shaped dial, the end of fork has roller, escapement is provided with return spring, escapement and fork are fixed together, fan-shaped dial maintains static, roller and fan-shaped dial contact, escapement part part in kind of box is exposed at outside kind of the box, escapement is provided with capsule kind nest eye, along with the rolling of dibbler, fork is subjected to the effect of fan-shaped dial and swings, and escapement is swing thereupon also, capsule kind nest eye goes out, goes into kind of a box, finish get again and again kind, the seeding action.The patent No. be ZL200420008021.X's " a kind of drum-type precision drill " disclosed be exactly be similar to above-mentioned dibbler a kind of.In the production application process, there is defective in above-described dibbler seed taking device, is exactly that return spring on the escapement surpasses fatigue limit easily and ruptures, and the poor reliability of work can not continuous operation in a sowing time, delays the time in busy farming season easily.

Three, summary of the invention

The purpose of this utility model is the deficiency that overcomes prior art, and a kind of not fragile, dibbler seed taking device that functional reliability is strong is provided.

The seed taking device of a kind of mechanical type dibbler of the utility model, comprise kind of a box, escapement and fork, escapement is provided with capsule kind nest eye, the fork front end is provided with roller, be characterized in: a price fixing is set in dibbler, below described price fixing, curve track is set, above described price fixing, back-up ring is set, described roller and described curve track are suitable, and when described roller entered described curve track, described capsule kind nest eye was exposed at outside kind of the box, the rear end of described fork is provided with the return inclined-plane, described return inclined-plane and described back-up ring are suitable, and when described return inclined-plane contacted described back-up ring, described capsule kind nest eye entered within kind of the box.

The utility model is owing to adopt curve track and the action of back-up ring control fork, the escapement swing finished get kind, the seeding action, do not need to be provided with back-moving spring, greatly improved the service life of each workpiece, improved the functional reliability of dibbler.On the other hand, the fork roller is in the curve track running, and escapement does not stop to rock, and it is kind more abundant that capsule kind nest eye is got, and reduces the hole.The utility model has the advantages that: each parts of seed-taking device are not fragile, functional reliability is high, adaptability is strong.
