Description:MANUAL/TRACTOR DRIVEN MULTI CROP SEED SOWING MACHINE

Agriculture plays an important role in life. It is the backbone of our economic system. The Manual/Tractor driven Multi-Crop seed sowing machine is developed to solve the clustering problem faced by our farmers while broadcasting the seeds. The mechanism is simple, and it works on the principle of line sowing, seed injection mechanism, seed metering principles. This sowing machine is suitable for all types’ of seeds which vary in size. This machine which is operated manually or is tractor driven, the spacing and depth between the seeds can also be varied. This increases the planting efficiency and accuracy and reduces the efforts of farmers.
Background of the Invention:

Depth of the seed, distance between two seeds, soil moisture, Ph of the soil plays an important role in the germination of the seed. Various plant type tend to branch out creating more yield. These types of plants should be properly spaced out during the seeding process. Currently, seeds like sesame, mustard are sown using broadcasting method (random dispersal of seeds). This methodology leads to clustering of seeds, hence branching is not possible. Further even distribution of nutrition to all seeds cannot happen.

The invention can create a line sowing pattern. This helps the farmers to bring in various other farm machinery, because, in the broadcasting method, due to clustering, there will be a uneven plant distribution and farm machinery cannot adapt to that and may damage useful plant.

This invention can also inject encapsulated fertilizer into the soil.
Brief principle:
The invention uses a specialized seed cup that is mounted to exactly sow the desired number of seeds. A line sowing principle with seed injection technology is used by the present embodiment.
The present embodiment helps avoid wastage of seeds and uneven coverage of the land due to uneven distribution by its mechanized form. Through broadcasting, it is quite difficult to carry out further processes like weeding, spraying, thinning, and harvesting. Due to improper distribution of water and nutrients, poor performance of the crops is established when the seeds are not sown in right depth which also fails to give good seed-soil contact and results in uneven plant distribution or spacing when broadcasting. Further, manpower and time for sowing is high and is a premium in agricultural sector presently.
Detailed Description of the Invention:
In the invention, there is a seed cup inside which cup there is a seed disc. Seed Disc is a user replaceable part which has a varied number of holes radially depending on the seed, which rotates to pick the determined amount of seed and drop it to the seed pipe. The seed pipe is attached with the Bi-fulcrum cone, which plunges down at the determined depth inside the soil through crank mechanism. After plunging the soil Bi- fulcrum cone opens through spring actuation to drop the seed, after which the cone closes and the seed pipe returns to the original position.
Size of the seed and Number of seeds to be sown per plunging can be adjusted by changing seed disc holes size. This plunging mechanism is modular and can be increased as per the need of the user. The Row and column spacing between the seed can be adjusted by moving the plunger along the axis and changing the size of the sprockets. The depth of the plunging can be altered be adjusting Crank mechanism.
Seed cup (1)

Seed Cup is a conical structure, with grooves that carry the bulk material (Seed) from the hopper. It consists of a disc, rotating shaft, opening at the bottom to transfer the seed to the seed pipe.

Seed disc (2)

It is a circular shaft consisting of holes placed radial in direction. Number of holes differs based on the nature/ Type/Number of the material to be plunged. The size of holes will be changed according to the size & type of the material. The invention comes with a set of user interchangeable seed discs, based on the nature/ Type/Number of the material to be plunged. The disc in future shall be customizable according to the need of the user. The disk rotates to carry the material towards seed pipe.

Transfer tube (3)

Transfer tube is a smooth path connecting the seed cup and the seed pipe.

Seed pipe (4)

It is a tubular structure, connecting the crank mechanism to the Bi-fulcrum cone.

Bi-fulcrum cone (5)

Bi – Fulcrum cone is a special structure with two separate conical part which is connected to form a frustum. This part has direct contact with the ground. The material of frustum is an alloy that possess hardness to pierce the ground and at the same time malleable in nature bend when hitting a rock, coupled with good endurance. The function of the frustum to open and close when material reaches the end.

Crank mechanism (6)

It is considered as the heart of the system. It consist of a crank, crank shaft and connecting rod. The connecting rod is connect to the seed pipe. The crank shaft rotates by the drive wheel. The crank shaft is connected to the crank which rotate to reciprocate the seed pipe.

Spring actuator (7)
The spring actuator consist of spring and the steel wire. When the seed pipe plunges and touch the soil the wire connected to the Bi- fulcrum cone extend to opens the cone. After plunging the cone closes by spring actuation.

Drive system (8)
The system can be powered by chain and sprocket mechanism. There are two drive system, one to rotate the wheel - injection mechanism and other is to drive the injection mechanism - seed disc. The ratio of sprocket determined the depth and distance of sowing.
, Claims:1. An agriculture seed-sowing apparatus, comprising:

A seed cup (1), a tapered container for filling material such as Seed/crop or fertilizer, designed to dispense its contents onto a seed disc (2) which rotates along the drive, which is a circular component, with one or more holes depending on the type, size and/or the number of materials needed to be plunged at a single instance, to transfer the material at a defined quantity to the seed pipe (4) through the transfer tube (3) and the seed enters the Bi- fulcrumed cone (5) which plunges the Bi-fulcrumed cone (5) onto the soil and opens after the cone reaches a certain depth, where the depth of the plunging action can be configured through the crank mechanism (6) which also changes the motion of the seed pipe (4) and the Bi-fulcrumed cone (5) as per requirement and the Bi-fulcrumed cone (5) closes after the insertion of the seed where the opening and closing of the Bi-fulcrumed cone (5) is accomplished by the spring actuation (7)

2. The agriculture seed-sowing apparatus of claim 1, further comprising a bi-fulcrumed frustum (4) for opening and closing based on material reaching the end, comprising a structure with two separate triangular concave parts connected to form a frustum, having direct contact with the ground and possessing sufficient hardness, toughness, and durability.

3. The agriculture seed-sowing apparatus of claim 1, further comprising a drive system (7) for powering the sowing apparatus, comprising a chain and sprocket mechanism, where one drive system moves the wheel and flywheel, and another drive system drives the injection mechanism and seed disc.

4. The agriculture seed-sowing apparatus of claim 1 and 3, wherein the ratio of the sprocket determines the depth and distance of sowing.

5. The agriculture seed-sowing apparatus of claim 1, further due to its modular design, additional Bi-fulcrumated cones (5) along with the corresponding number of seed pipes (4), can be added which still has one seed cup (1) with the corresponding number of transfer pipes (3) and seed pipes (4) where the materials from the seed cup (1) will pass through the seed pipes (4) in equal quantity to each of the Bi-fulcrumated cones (5), where the horizontal spacing between each of the Bi-fulcrumated cones (5) can be changed according to the requirement.
