The following specification describes the invention.
þ COMPLETE

The following specification particularly describes the invention and the manner in which it is to be performed.

FIELD OF THE INVENTION

The present invention relates to an agricultural boom sprayer. More particularly it relates to a self propelled agriculture heighted boom sprayers for spraying pesticides or chemicals over crop fields.

BACKGROUND OF THE INVENTION

The term pesticide covers a wide range of compounds including insecticides, fungicides, herbicides, rodenticides, molluscicides, nematicides and plant growth regulators. Seed treatments are usually achieved by effective dose-transfer to a crop. Pesticides are applied to the seed prior to planting in the form of a seed treatment or coating to protect against soil-borne risks to the plant. Additionally, these coatings can provide supplemental chemicals and nutrients designed to encourage growth.
The manual spraying apparatus is available in which spraying is achieved by portable spray pump. But there are certain disadvantages associated with these sprayers such as it is highly time consuming which leads to infection in crop and affect the productivity of the crop.
CN 2422059 relates to a piston for a knapsack hand-operated sprayer. A piston for the sprayer comprises a fluid passageway, the piston, a piston barrel, a piston rod, a back flow hole and a piston cap. The problem associated with the manual knapsack sprayer is that it is time consuming and laborious work.
CN 2083851 relates to a knapsack high pressure sprayer, which is an agricultural machine and is mainly composed of a solution barrel and a high pressure assembly which is installed on the solution barrel, wherein, a spraying rod and a spraying head are connected with the high pressure assembly through a water outlet pipe. One disadvantage associated with this invention is that a high pressure sprayer is required to be operated by more than two persons. Also, it has the disadvantages of inconvenient operation and large labor intensity.
These sprayers further require manual efforts for pumping. Therefore user gets tired after a little use of the sprayer and does not cover full crop uniformly. Also, both the hands of the user remains engaged and therefore the user can not use the sprayer for a long time. When person spraying manually, he has a chance to got affected by pesticides or chemicals due to his position that of closer to field crops.
Hence, it is needed to have a self propelled agriculture heighted boom sprayer that solves aforesaid problems and to have quite efficient engines and simple electronics for carrying out spraying adjustments and repairs. Also fuel used is diesel which is economical and easily available.
OBJECT OF THE INVENTION

The principle object of the present invention is to provide a self propelled agriculture heighted boom sprayer.
Another object of the present invention is to provide improvement in efficiency, time and effectiveness of spraying against the manual spraying practices.
Another object of the present invention is to provide a sprayer which is readily modified to accommodate raw crops of different heights (from 550 mm to 1800 mm) or raw crop of different farm sizes.
Still another object of the present invention is to provide increased spraying accuracy and productivity.
Yet another object of the present invention is to provide better stability and balancing of machine by specially designed pesticides or chemicals tank dimensions and capacity.

SUMMARY OF THE INVENTION

The present invention relates to a self-propelled agriculture heighted boom sprayer for spraying chemicals or pesticides which consists of a height adjustable (from 550 mm to 1800 mm) pesticides or chemicals control unit being mounted on the front axle, a pesticides or chemicals holding spray tank being located behind the driver’s seat, a diesel engine being mounted on the fabricated chassis behind the tank, a hydraulic power steering mounted on front axle, a spray pump with electromagnetic clutch being mounted nearer to the tank and transmission unit. The transmission unit consists of a hydrostatic transmission system mounted nearer to the engine; a transmission gear box mounted nearer to the hydrostatic transmission system; and a differential drive corresponding to each of the wheels. The said agriculture heighted boom sprayer also consists of a left boom operating lever and right boom operating lever which is operated manually to swivel a pair of swivelling booms at 90° to align the direction as the fixed boom and after that spraying is formed by pumping the chemicals or pesticides from the tank through spray pump via boom nozzles.
