Abstract

The utility model discloses a seeding rate adjustable cell wheel seeding apparatus, which is composed of a seed box (1), a casing (2), a cell wheel (4), a seed receiving cup (5), a regulating plate (3), etc. Seeds in the seed box (1) enter the cell wheel (4) through the casing (2), and the cell wheel (4) is provided with a small groove (11). The seeds are transported into the seed receiving cup (5) quantificationally and seeded in the ground uniformly through the rotation of the cell wheel (4). The position of the regulating plate (3) can be regulated to adjust the amount of the seeds which enter into the cell wheel (4). Thereby, the utility model reaches the goal of regulating the seeding quantity and saves labor force greatly. The utility model has the advantages of simple structure, low manufacture cost, reliable operation, high seeding precision and better economic and social benefits.

Description

Nest eye Type Seed Metering Device that the amount of broadcasting is adjustable

Technical field

The utility model relates to a kind of seeding unit, particularly relates to the adjustable nest eye of a kind of amount of broadcasting Type Seed Metering Device.

Background technology

At present, rapeseed cultivation mainly adopts method for culturing and transplanting seedlings, and this method labour intensity is very big.Show according to data: if grasp the cultivation time, the method for culturing and transplanting seedlings of rape and no-tillage drilling or broadcast sowing on output very nearly the samely, and labour's input is saved greatly.In order to alleviate peasant's labour intensity, labor savings realizes the mechanization process to agricultural production, actively realizes the agriculture requirement reform to crops when developing suitable farm machinery.

The utility model content

Technical problem to be solved in the utility model provides a kind of adjustable nest eye of the amount of broadcasting Type Seed Metering Device that is applicable to drilling of granule seed or bunch planting.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: nest eye Type Seed Metering Device that a kind of amount of broadcasting is adjustable, it is characterized in that: above housing, be provided with seed-box, the below is provided with an inoculation cup at least, at least being provided with a seed flow inlet that connects with described seed-box and at least one on described housing exports with the seed flow that described inoculation cup connects, in described housing, be provided with one can with its adjustable plate in relative rotation, on described adjustable plate, be provided with and described seed flow inlet and corresponding seed inlet and the seed export of seed flow outlet, in described adjustable plate, be provided with one can with its nest eye wheel in relative rotation, at least be provided with a sulculus on described nest eye wheel, described sulculus can enter the mouth and the corresponding perforation of seed export with described seed respectively in different phase places.

Adopt the adjustable nest eye of the amount of the broadcasting Type Seed Metering Device of technique scheme, seed in the seed-box enters the mouth by the seed flow on the housing, enter the sulculus in the nest eye wheel, rotation by nest eye wheel, seed in the sulculus exports by seed flow, quantitatively be transported in the inoculation cup, seed is broadcast in the ground equably by the inoculation cup.

The utility model has the advantages that significantly it has realized that by the rotation of nest eye wheel seed flows equably, and can regulate seeding quantity as long as change the position of adjustable plate, has saved the labour greatly.The utility model is simple in structure, low cost of manufacture, and reliable operation, the seeding accuracy height has favorable economic benefit and social benefit.

In sum, the utility model is a kind of adjustable nest eye of the amount of broadcasting Type Seed Metering Device that is applicable to the drilling of granule seed or bunch planting and simple in structure, low cost of manufacture, reliable operation, seeding accuracy height, has favorable economic benefit and social benefit.

Embodiment

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, above housing 2, be provided with seed-box 1, the below is provided with three inoculation cups 5, on housing 2, be provided with three 9 and three seed flow outlets 10 that connect with inoculation cup 5 of seed flow inlet that connect with seed-box 1, in housing 2, be provided with one can with its adjustable plate 3 in relative rotation, on adjustable plate 3, be provided with seed flow inlet 9 and seed flow and export 10 corresponding seed inlet 7 and seed exports 8, in adjustable plate 3, be provided with one can with its nest eye wheel 4 in relative rotation, being axially arranged with eight row sulculuses, 11, eight row sulculuses 11 on nest eye wheel 4 can be respectively and seed inlet 7 and seed export 8 corresponding perforations in different phase places.

During work, the power of sower is transferred to nest eye wheel 4 by axle 6, drives nest eye wheel 4 and rotates.Referring to Fig. 2 and Fig. 3, on nest eye wheel 4, have several rows of sulculus 11, in a certain moment, the sulculus 11 on the nest eye wheel 4 turns to seed-box 1 bottom, and the seed in the seed-box 1 enters in the nest eye wheel 4 by the inlet of the seed flow on the housing 29, and sulculus 11 is filled up.When nest eye wheel 4 turns an angle, when sulculus 11 turned to inoculation cup 5 tops, the seed in the sulculus 11 quantitatively fell into inoculation cup 5 by seed flow outlet 10, and seed is broadcast in the ground equably by inoculation cup 5, thereby has realized the drilling or the bunch planting of seed.

Referring to Fig. 1, Fig. 4, Fig. 5, Fig. 6, Fig. 7, in order to regulate seeding quantity, between housing 2 and nest eye wheel 4, arrange an adjustable plate 3, on adjustable plate 3, be provided with seed flow inlet 9 and seed flow and export 10 corresponding seed inlet 7 and seed exports 8, the quantity that seed enters sulculus 11 in the nest eye wheel 4 can be regulated in position by seed inlet 7 and seed export 8 on the adjustment adjustable plate 3, thereby reaches the purpose of regulating seeding quantity.

The utility model has the advantages that significantly it is real by the rotation of nest eye wheel Showed seed and flowed equably, and can regulate as long as change the position of adjustable plate Application rate has been saved the labour greatly. The utility model is simple in structure, makes Cost is low, reliable operation, the seeding accuracy height, have preferably economic benefit and Social benefit.
