Description

Spoon amount ratchet seeding Device

Technical field

The present invention relates to a kind of family property seeding machinery, especially for little granule, such as Brassica campestris L, the spoon amount ratchet feed mechanism for seed of the crop-planting such as Semen Sesami, millet, Sorghum vulgare Pers., Semen phaseoli radiati.

Background technology

The feed mechanism for seed that existing agricultural seeding machine uses, mostly be drilling, hole roller and use hairbrush and rubber brush brush kind, both made be bunch planting be also pull-up formula, it is impossible to definitely grain seed quantity, charge seed many, seed fraction has damage, and kind brush is easy to wear, and fault is more, Seedling input cylinder spoon of picking up heavy after broadcasting scoops seeder, large area can not work continuously a difficult problem, make peasant planting cost up, income reduce.

Summary of the invention

Present invention aim to the deficiency overcoming prior art to exist, there is provided a kind of for the spoon amount controllable including little grain seed crop without hairbrush and glue brush, the most sternly, do not jump, do not alter, do not squeeze, novel (specially essence is special new) feed mechanism for seed of injuring-free seed, can use by supporting multiple seeder, there is simple in construction, installation and debugging convenience, dependable performance, operation function entirely, adapt to the spoon amount ratchet feed mechanism for seed of the feature that large area is worked continuously..

The present invention is realized in, connected by feed mechanism for seed shell and bonnet and form seeder unit shell, seed entrance, adjustable kind amount plate it is provided with in the back upper place of housing, install in seed entrance and put kind of a mouth, in housing, leak-proof device composition is arranged below closes kind of a chamber, spoon amount ratchet is installed by six side's seed shafts in middle part, is provided with seed-pretecter and funnel, is externally provided with connector, pilot hole at housing in housing；

The outer rim of above-mentioned described spoon amount ratchet is provided with and scoops kind of a spoon, scoops kind of spoon and is made up of convergence arc after spoon scarp slope, spoon outslope, left slope, right slope, hill, hill.

Spoon amount ratchet feed mechanism for seed of the present invention has following construction features compared with existing common feed mechanism for seed:

1. at kind of chamber, seed is scooped kind of a spoon in free state and is scooped in spoon, ladder type spoon cave, does not squeeze seed and easy to fall off, injuring-free seed；

2. seed can be protected by seed-pretecter in entering and scooping kind of spoon, does not jumps, does not alters, the most sternly, does not rubs；

3. the regulation of feed mechanism for seed kind amount is simple and convenient, the plate being located at seed inlet control, and is adjusted up plate flow rate and increases (seed grain is many), otherwise flow rate diminishes；

4. changing different seed wheels according to the seed of different-diameter size kind with sowing spacing in the rows, can broadcast the seed within diameter one millimeter to 10 millimeters, can broadcast multiple seed, function is complete；

5. seed inlet is arranged over big seed-box, can the continuous seeding operation of large area；

The seeder that my company produces the most not only is installed, it is possible to support the use to the upper ridge tectorial seeder of same industry production and full-film covering machine；

7. simple in construction, installation and debugging are convenient, and dependable performance, operation function is complete；Reducing production cost, selling price is cheap.

Detailed description of the invention

Describe in detail below in conjunction with the accompanying drawings: as shown in the figure, connected by feed mechanism for seed shell 3 and bonnet 4 and form seeder unit shell, seed entrance 1, adjustable kind amount plate 2 it is provided with in the back upper place of housing, install in seed entrance 1 and put kind of mouth 11, in housing, leak-proof device 8 composition is arranged below closes kind of a chamber, spoon amount ratchet 6 is installed by six side's seed shafts 9 in middle part, is provided with seed-pretecter 5 and funnel 7, is externally provided with connector 10, pilot hole 12 at housing in housing；

The outer rim of above-mentioned described spoon amount ratchet 6 is provided with and scoops kind of a spoon 6-0, scoops kind of spoon 6-0 and is made up of convergence arc 6-6 after spoon scarp slope 6-1, spoon outslope 6-2, left slope 6-3, right slope 6-4, hill 6-5, hill.

It act as:

Scoop kind of spoon 6-0 seeding wheel to rotate, scoop kind of spoon depression mouth upward, scoop kind of rate 100%；

Spoon scarp slope 6-1, when scoop kind of spoon has seed run to upper top turn to descending time, stop seed alter, slip；

Spoon outslope 6-2, one is the seed height controlling to scoop in spoon, certain less than bucket wheel outer unit face, two be spoonful outward flange to bucket wheel outer unit week away from determination, be the 1/3 of the seed diameter that need to broadcast；

Left slope 6-3, right slope 6-4, scoop kind of spoon when seed free state, and seed is easily scooped in spoon, and through sowing port, seed easily departs from and scoops kind of a spoon；

Hill 6-5, one is to scoop after kind of a spoon scooped one spoonful, protruding position, though without departing from wheel outer rim also can seed in disturbance seeds chamber fluffy, two is non-return leakage small-sized seed；

Restraining arc 6-6 after hill, the seed of disturbance starts return, and along with wheel camber streamline convergence inertia, seed is easily scooped in spoon.

During use, by pilot hole 12 connection frame；Seed drives spoon amount ratchet 6 to rotate through adjustable kind amount plate 2 by six side's seed shafts 9; seed is scooped in spoon by kind of the spoon that scoops on spoon amount ratchet 6; protection through seed-pretecter 5; from sowing port 7(funnel) discharge; broadcasting a cave according to agriculture requirement one spoonful, after fulfiling assignment, remaining seed can be released by putting kind of mouth 11.
