Full Text Field of Invention
The present invention relates to a seed cum fertilizer sowing machine for sowing seeds and applying fertilizer at different depths of soil.
Background of Invention
In traditional agriculture the farmer uses the one box seed drill to sow seeds as well as to spread fertilizer with the result that both the fertilizer and the seeds are deposited at the same spot and at the same depth. When the seeds sprout, the weaker seedlings are unable to withstand the heat generated by the fertilizer and wilt and the stronger seedlings that survive soon grow roots beyond the layer in which the fertilizer exits. In this way the crop does not get the full benefit of the fertilizer. The farmer seeing his weakening crop, disregards scientific counsel and applies more fertilizer to the field, incurring more expenses, but benefits little from it. Excess fertilizer contributes to the degradation of the land.
To counter this problem agricultural scientists advise farmers to first plough the field thoroughly and apply fertilizer and then sow the seeds over the layer of the fertilizer. However, even this has disadvantages. It is seen that even after doing this, the seeds are not uniformly broadcasted, with some falling well below the layer of fertilizer, some far above and some at the level of the fertilizer. Also this method requires the farmer to work his field twice, with additional costs and labour involved. Although this method produces better yield, the farmer incurred extra costs.
In view of all these problems, first a two box seed cum fertilizer was devised which was initially pulled by bullocks and later attached to a tractor. This contraption applies the fertilizer and the seeds to the stipulated depth simultaneously. This invention thus has a potential to benefit the farmers immensely and increase their yields substantially at the same time saving them time, labour and money.
Accordingly this machine can bring about a substantial reduction in the wastage of fertilizer. It can also considerably reduce the damage caused to the
soil by the excessive use of chemical fertilizers. Using this machine farmer can sow and fertilize different types of crops of both rabi and kharif cycle as per the scientific requirement of each crop and by reducing the amount of fertilizer needed, can bring about a major gain to farmers in terms of input costs. At the same time, by getting bumper crops from their fields farmers stand to gain economically, The reduced use of fertilizers also keeps their soil healthy for the next crop. Since there are separate containers for the seeds and the fertilizer, the left over seeds and fertilizer do not mix and can be removed and stored separately for future use. Since the crop uses the full amount of the fertilizer applied, phosphatic layers do not form over the fields. This keeps the soil porous and absorbs all the rainwater, thus increasing the ground water storage. Therefore, this machine also makes a significant contribution to water conservation.
Detailed description of the invention
The present invention can be pulled by both bullocks and tractor, as it has been developed in two different sizes. This machine can apply fertilizer and seeds simultaneously. The front legs of the machine inject fertilizer into the soil and the rear legs sow the seeds. The distance between the front and rear legs can be adjusted to a minimum of 10 cms and the upper limit is as per the requirements of the crop. The machine requires atleast one type of seed and one type of fertilizer to function. The main claim of this invention is its adjustable legs, which is a feature that is the not found in any other such machine. All other machines have only one leg, which ejects both seeds and fertilizer, and therefore it is not possible to vary the depths at which both are applied. In this machine the fertilizer is applied deeper in the root zone of the crop as recommended by agricultural scientists, while the seeds are sowed at a slightly less depth.
The machine has three units:
Box
Cultivator
3. Arm wheel Box:
The box has a separator in the middle, which divides the inner space into two. In the front potion fertilizer is kept and in the rear portion the seeds are kept. Both these compartments have outlet holes through which the seeds and the fertilizer come out. In front of each of these holes are rotating shafts that are controlled by the arm wheel of the cultivator. These shafts have a rubber washer attached to their ends, which pushes the seeds and fertilizer into the funnels fitted below the holes. Near the exit holes locks have been placed to keep the washer in place. By manipulating the washer, the amount of fertilizer or seeds ejected can be controlled. The noses of the funnels are connected to PVC pipes which guide the fertilizer and the seeds to the front and rear legs respectively. The outlets have a lever, which is activated when the machine is activated when the machine is touching the ground and is deactivated when the machine is lifted above the ground. In this way the sowing and fertilizing operation is automated. The farmer can also manually operate the lever. The box containing the seeds and the fertilizer has been specially designed. The same chain moves the shafts connected to both portions of the box, which is also the novelty of this machine.
The cultivator:
The cultivator has a central importance in this invention. It has been designed differently from the cultivators of other machines. In the present design, different sets of legs distribute the seeds and the fertilizer. These legs are aligned one behind the other in a line. The cultivator has atleast one leg for fertilizer and one for the seeds. The minimum distance between the front and rear legs can be reduced to 10 cms and can be increased to any limit depending on the requirement of the crop. The front legs broadcast the fertilizer to the desired depth and the rear sow the seeds. The seeds can be distributed so that there is a specified distance between each set of seeds grown. The seeds are sown after covering the fertilizer broadcasted by the front legs with a layer of soil. Because of this there is a difference in the depths at which the fertilizer and the seeds are
applied. After the seeds have been sown, a plank levels the ground and covers the seeds with soil. The number of legs in the cultivator can be increased as per requirement. Bullocks as well as tractor can pull the cultivator. Separate designs are available for both.
Arm Wheel:
When the machine touches the ground, the friction with the ground forces the arm wheel to rotate and move a chain, which in turn rotates the shafts that release the fertilizer and the seeds from the box.
