Field of the Invention:

The present invention generally relates to One Pass Seeder Assembly, an improved agricultural implement which particularly comprises of novel one pass seeder tynes provisioned for uniform digging of deep furrow in field, simultaneous dropping of seed along with the Fertilizer/agrochemicals through drop-channels provided just behind the furrow opener and thereafter instantly putting soil-cover above the said seed and fertilizer dropped in the said furrow.
The operations performed by the instant One Pass Seeder is characterised by uniform dropping of seed and fertilizer in the deep furrow followed by soft-soil covering instantly above said seed and fertilizer, leading to effective protection of said seeds from birds and ensuring germination of said soil covered seeds in better manner.

Background of the present invention:

Crop seeder as an agricultural implement is well known amongst the farmer across the globe, which is generally applied for furrow opening and uniform crop/seed placement thereof. As far as Indian agricultural scenario is concerned, a well-known such equipment is Happy Seeder. The technology of such Happy Seeder was developed by Punjab agriculture University 10 Years back. Now a day it is being made by many of the agricultural implement manufacturing firms, wherein said happy seeder machine is made to solve the problem of biomass handlings and to stop paddy stubble burning.
Conventional happy seeder equipment has certain drawbacks in its construction and operation, leading to practical seeding issues, and therefore it is not yet popular amongst the farmers.
Drawbacks of conventionally known happy seeder:
• It’s seeder tynes are equipped to create furrow up to three inches, leading to harder seed bed;
• It’s seeder tynes are not equipped with device for performing the action of putting soil cover after dropping the seeds and fertilizer in the furrow, leading to complete exposure of seeds to birds and other insects of open weather. Such open furrow throughout the field, having seeds exposed to birds, insects and other weather-parameters, is main concern to farmers, due to following reasons:
? Loss of yield- Most of the farmers have doubt that yield will be lesser as compare to available traditional method with respect to application of happy seeder. Many of the farmers experienced low yield.
? Crop falls- This is biggest issue. In month of March, crop fall down because of grain development on top of the plant. As per our study this happens because we sow the wheat directly just after paddy harvesting. The field surface remains very hard because of standing water up to 100 days in paddy.
? Strength & growth of Root- Root strength becomes poor as compare to traditional method as seeds are placed on hard surface. The new invention resolved this major issue.
Conventional Happy Seeder Tyne Design and Working Principle:
Conventional Happy seeder consists of sharp tyne blade, made up of alloy steel and equipped with seed and fertilizer pore(s). This sharp profile of tyne makes 3 inches deep furrow in hard surface of paddy field and thereafter the drop-pore drops seed and fertilizer in said furrow over hard field surface. This leads to less germination and lesser root growth as shown in figure 1.
The seed and fertilizer remains in furrow open to the environment which is also the major issue in the conventional design of such seeder implement.
To overcome the above drawbacks of the conventional agricultural seeder implement like Happy Seeder, the prime object of the present invention is to provide an advanced One Pass Seeder with novel constructional and functional features thereof.
Another prime object of the present invention is to provide One Pass Seeder assembly, an improved agricultural implement which particularly comprises plurality of novel One Pass Seeder tynes equipped with devices for uniform digging of deep furrow in field, simultaneous dropping of seed and the Fertilizer/agrochemicals through drop-channels and thereafter instantly putting soil-cover above the said seed-fertilizer mixture dropped in the said furrow.
Another object of the present invention is to provide novel One Pass Seeder tynes, comprising of sharp tyne blade for creating a furrow of 3-4 inches, rigidly mounted drop-channels on said blade profile for dropping the seed and fertilizer/agrochemical(s) and
Another object of the present invention is to provide a preferred embodiment of the One Pass Seeder, wherein its operations performed are characterized in uniform dropping of seed and fertilizer in the deep furrow followed by putting soft-soil covering instantly above said seed and fertilizer, leading to effective protection of said seeds from birds and ensuring germination of said soil covered seeds in better manner.
Summary of the present invention:
The present invention generally discloses a novel construction of tyne assembly, capable of performing three functions simultaneously: digging the furrow, dropping the seed and fertilizer (and/or other agrochemicals like fungicides) and covering the said seed-fertilizer with soft soil, cutting from at least one side of the said furrow thereof. Accordingly, an array of such novel tyne assembly, preferably in 3 to 24 tynes in number and more preferably 5 to 12 tynes in number, is installed together in the form of an integrated agri-implement as One pass Seeder, suitable to be operated/driven by a tractor in the field.

Detailed Description of the Invention:
Constructional aspects of the one pass seeder tyne assembly (1) of the instant invention and its working principle:
Construction:
• Tyne consists of sharp edge blade made up of alloy steel.
• The drop-channel or the pore for releasing the seed and the fertilizer is made up of steel pipe.
• The dimension and shape of said pour is optionally so chosen that, the seed and the fertilizer (and other optional agrochemicals), coming from the hopper get dropped smoothly without any hindrance in the flow path.
• The outlet of said pour or drop-channel is positioned below the said main shaft of the tyne blade at appropriate height.
As shown in Figures 2 to 4, the main shaft (2) of said tyne blade (3) is provided with two discs, (5) and (6), at backside of the main shaft (2), one at the left side and other at right side, located with offset centres and having some defined angle in centre axis of shafts. The disks is to be mounted with the main shaft (2) of the tyne blade and the diameter of said disks (5) and (6) concaved inwardly, are optionally selected, mainly based on the amount of soil to be cut from the edges of the furrow created by the said tyne blade. As a matter of optional preference in one embodiment, one of the discs (5) which is positioned comparatively nearer to the blade (3) is kept steady/rigid at its mounting arm (4a) and another disc (6) is mounted hingedly at mounting arm (4b) at an angle or in a manner to allow it to rotate therein.
In one of the preferred embodiment of the One Pass Seeder assembly (1), the tyne blade (3) is mounted at lower edge of the main shaft (2). Using mounting arms (4a) and (4b), two discs (5) and (6) respectively are mounted with the main shaft (2), wherein the disc (6) is hingedly mounted thereof. Said main shaft (2) is installed with the vehicle/agri-implant body using nut-bolts at the mounting bracket (11). At the backside of the said main shaft (2), the pore or the drop-channel (7) for seed and fertilizer is positioned. At upper side of said pore or the drop-channel (7) for seed and fertilizer is preferably provided with two openings (8) and (9), wherein one of said two openings supply seed and the another one supply fertilizer into the upper region (7a) of the said drop-channel (7). Said upper region (7a), preferably a cone-shaped region therein with comparatively larger volume therewithin is created below openings (8) and (9), where seeds and fertilizers coming from openings (8) and (9) are received and intermixed and thereafter get released into the main pore pipe of said drop-channel (7). The lower pore-opening (10) of the said drop-channel (7) is positioned just at the backside of the blade (3) of the main shaft (2) so that the seed-fertilizer mix is correctly released at the deepest position in the furrow, exposed to said pore-opening (10).
One Pass Seeder, as provided in the instant invention comprises of an array of such novel tyne assembly (1), preferably in 3 to 24 tyne assemblies in number and more preferably 5 to 12 tyne assemblies in number, and further more preferably 10 tyne assemblies, installed to together in the form of an integrated agri-implement as One pass Seeder, suitable to be operated/driven by a tractor in the field.
Working:
• The sharp edge blade (3) of tyne will make 3-4 inches deep furrow.
• The pore pipe (7) will put seed and fertilizer in 3-4 inches deep furrow.
• The pore pipe is followed by first disc (5) at some defined cutting angle and this will shear side soil in furrow to provide soft soil base for seed and easy mixing of fertiliser.
• Second disc (6) will push the soil on edges of furrow above the seed and fertiliser to cover the seed and fertilizer thereby preventing it from bird and other harmful weather parameter.

Root comparison in maize crop, seeded with one pass seeder of the present invention and with the conventional tynes of Happy seeder:-
Jagatjit Tynes Modified Design (Prior art analysis):
• Maize plants were sown over a part of land with conventional happy seeder, wherein one tyne assembly of said agri-implement was replaced by the new tyne assembly of One Pass Seeder of the present invention (Figure 5 and 6 herein below).
• This happy seeder consists of 10 tynes, One of the conventional tyne of said happy seeder was removed and the new tyne assembly of the present invention, as proposed for the “One Pass Seeder” was installed thereof; primarily with the intension to operate the conventional and modified tyne assemblies at a time in the same field environment (ref. Figure 5 and 6 herein below).
• After one month of sowing, we picked some sample maize plants from field for root comparison (figure 7 and 8 hereinbelow).
• The results were very positive showing efficacy of new tyne assembly of the One Pass Seeder. The roots of maize plant seeded with modified Tyne were lengthier and more developed than the maize plant seeded with conventional Tyne.
Expert Reviews on Root comparison:
• Dr. Amrik Singh (Agriculture officer, Pathankot region) contact no. 9463071919.
• He advised the standard procedure to compare roots of two different plants of same crop in same field (Figures 5 to 9).
Expert inferences:
1. According to Dr. Amrik Singh the germinated maize plants sown with modified concept have more developed root than conventional Tyne (Figures 8 and 9 hereinbelow).
2. According to Dr. Amrik Singh the germinated maize plants sown with modified concept have more no. of hair roots (figure 9 hereinbelow) which are necessary for plant grip with soil.
3. Comparison of structural features of the Prior Art with the New One Pass Seeder of the instant invention is shown in Figures 10, 11 and 12 hereinbelow. Figure 10 shows the representative views of conventional happy seeder equipment as conventional arts and it also shows the main schematic view of the One Pass Seeder. Figure 11 shows the real working of the complete “One Pass Seeder” as agri-implement, which is preferably driven by a tractor in the field for performing three functions in its single trip.
