Tilling is the process in which one is required to remove weeds or unwanted crops from the field, so that it may not obstruct the growth of the crop which is being intended to grow on the field. As there are weeds and unwanted crops on the field then it may consume the nutritious elements which are intended for the crop that is to be grown. So, here we have designed a machine which would uproot the weeds and unwanted crops from the field completely. In order to perform this operation in efficient and less time consumption manner we have implemented a system which obtain driver from the engine so the working of system is highly compact. In the working model tiller blades are attached with the wheel shaft and the sprocket which gets coupled with the shaft is attached with the engine flywheel by means of chain drive or belt drive based upon user convenience. According to our survey, to nearby fields we came to conclusion that the tilling process which is traditionally done by use of animals or employing labor according the size of the field is very time consuming and the cost of tilling the field traditionally is quite high. So, our machine fulfills the promise of helping out our farmers with the help of technology.
Soil preparation is the first and most important operation in agriculture. Destruction of weeds and to cut up crop residues is called as Secondary tillage in agriculture field. Secondary tillage is performed after some time interval of plant growing and is undertaken for
1) Weed control and uproot unwanted crops
2) Incorporation of fertilizers
3) Leveling soil surface.
The main objectives of soil preparation are, to improve the physical conditions of soil, to destroy weeds and to prepare a suitable seedbed. Rotary tiller is advantageous over the conventional implements (i.e. moldboard plow and disk plow) due to two main effects of the direct application of power to the soil engaging tool rotating around a horizontal-transverse axis. From decades, farmers use animal and human efforts for destruction of weeds and to uproot the crop residues. The basic idea of soil scratching for weed control is ancient and was done with hoes or mattocks for millennia before cultivators were developed. Cultivators were originally drawn by draft animals (such as horses, mules, or oxen) or were pushed or drawn by people. But it is very time consuming and also animals have limited range of working conditions and limited daily working hours. Also unavailability of workers and their high wages makes it more a headache. There is a need to design machines and tools relating the operations with minimum power required and maximum efficiency possible. On design aspects there are different factors to be considered such as tool profile, tool position, and flexibility to adjust with varying characteristics of regional soil, etc. These above technical aspects are needed to be considered for the features of machine to increase efficiency and effectiveness. There is a particular need to improve the farming methods and create method more efficient by providing new technologies and fabricating new equipment.
Two benefits of the direct application are
(i) rotary tiller achieves both plowing and harrowing in a pass of machine on the field and
(ii) the traction demanded of driving wheel is reduced due to the rotary blade provide some forward thrust as operating. Hence, the design of Weed Uprooting Machine with Grass Cutter is done.
The working model consists of engine which is mounted to the frame. The overall frame setup consists of wheel arrangement which is helpful for transporting this setup from one place to another. The roto tiller blades are mounted at the front portion of the frame and these blades are activated by means of coupling it with the engine output shaft with the help of chain or belt drives. When the engine gets started it tends to rotate the output shaft and this rotation is transferred to roto tiller by means of chain drive so it gets activated and by moving this setup over a field it performs the cutting operations. Due to the engine drive the power obtained is maximum and efficiency of work is maximum when compared to the existing models.
- It is one of the great saver of time and expenses on field operations.
- Because of smaller size, two wheels and limited constructional arrangements, the soil tiller becomes one of the lightest yet most effective farm power sources.
- Its operations are controlled by an operator through its extended handles by walking behind it.
- It makes the soil tiller move forward through traction of its wheel with the ground and at the same time change the direction as operator desires.
- For agricultural purposes.
