FIELD OF INVENTION

This invention relates to a semi automatic cow dung cleaning machine in cow shed.

BACKGROUND OF THE PRESENT INVENTION

Catties are considered to have been one of the first animals domesticated by man for agricultural purposes. They were tamed to provide milk, meat and hides and for draft purposes. Where and when exactly this domestication started is not clearly documented historically, but it is thought that cattle were probably first domesticated in Europe and Asia about 8500 years ago. India has a very rich reservoir of genetic diversity and possesses some of the best breeds of cattle and buffaloes in the world. The country's population of 218.8 cattle accounts for 17% of the total world population of cattle. Now a days the keeping and rearing of cows and buffaloes is largely limited to one to five dairy buffaloes or cows, depending on the availability of unemployed or casually employed members in the family and also the carrying capacity of the wasteland, fallow land, canal bunds and road sides, are kept for supplementing the income of the family. Dairy animals in most of the economically weaker families are limited to one or two, and dung for fuel is the main saving because almost entire milk produced is sold for the payment of debt and interest. On an average one cow produces 18kgs of dung each day. For a herd of 100 cows that's a massive 12.6 tonnes in just-one week. So some people starting cow farming in which there will be more cows or buffaloes which helps them in earning their bread.

This cow farming needs more workers for maintenance which in turn consumes a considerable part of the profit. Moreover manually cleaning involves lot of human effort as one has to bend down frequently to collect the dung and then dispose it. Again it needs another round of cleaning by swiping the floor completely. This necessity of human effort leads to back pain and back bone problems. The advancement of technology has led to few devices such as conveyors, small excavators being used to clean cow dung in large farms and industries. However in case of few middle and small farms people find it hard to invest on such provisions for cleaning, so it is done manually. Hence we came with an idea of semi automatic cow dung cleaning machine in cow shed. We have designed and fabricated a small trolley like arrangement at low cost that can be used to clean the floor of cow shed easily and effectively. It is a design which looks more or less like a trolley with four wheels, fork, and brush. Brush is made to rotate with help of gear motor using belt drive.

DETAILED DESCRIPTION OF THE INVENTION

Summary of the invention

The present invention is a semi automatic machine used to clean the cow dung in cow shed. It has a frame attached with wheels which houses a rechargeable battery, gear motor, rotating brush and a transmission system to transmit the motion from handle to the fork. The transmission system is attached to the frame with the help of plummer blocks.

When the handle is rotated in the clockwise direction with the help of hand, the worm gear arrangement along with the worm gear shaft converts the rotary motion into linear motion in the fork link rod. As a result the fork link rod will move the fork up and down and make it touch the ground.

The rechargeable battery housed in the frame supplies power to the gear motor. The gear motor drives the pulley attached to the brush by means of belt drive which rotates the brush in the direction opposite to the direction of rotation of the wheel. The brush is positioned at the back of the fork. A switch is provided in the frame to switch ON and switch OFF the gear motor.

The machine is brought into the cowshed and positioned appropriately. Then the handle is rotated and fork is made to touch the floor of the cowshed. Then the switch is switched ON, so that the brush rotates which is also partially in contact with the ground. Now the machine is made to move in the cow dung area, so that the fork which is partially in contact with the ground pushes the dung and the brush which rotates at the back of the fork swipes the floor simultaneously. The above process can be repeated twice or thrice in the same direction to clean the floor of the cowshed.

Operation

The semi automatic cow dung cleaning machine is brought into the cowshed and positioned accordingly. Then the handle is rotated in the clockwise direction and the fork is made touch the ground. Then the motor is switched ON and the brush rotates which is partially in contact with the ground. Now the machine is pushed forward by holding the frame towards the cow dung so that the fork which is partially in contact with the ground cleans and carries the dung forward.

Simultaneously the brush which rotates at the back of the fork swipes the floor of the cowshed. Once if the dung is brought to the rear end of the cowshed, the handle is rotated in the anticlockwise direction and the fork lifts. Now the machine is pulled back by holding the handle. The above action is repeated twice or thrice in the same direction for better result.
