TITLE
MULTIPURPOSE BULLOCK OPERATED AGRICULTURAL EQUIPMENT
FILED OF THE INVENTION
The present invention relates to the Multipurpose Agricultural Equipment. More
particularly it is a tractor or bullock operated Multipurpose Agricultural Equipment, which can be utilize for ploughing, harrowing, sowing, interculturing, weeding, and harvesting. The frame mounted on a central shaft of wheels has an arrangement to attach different attachments. The device has the arrangement to vary the RPM of the metering system and thereby plant to plant distance. Push type mechanical linkage is provided to lift the attachment while turning. The arrangement is made to adjust the angle of penetration of the soil-working tool during the operation itself. The seed drilling attachment can be replaced with seating attachment while transportation.
BACKGROUND OF THE INVENTION
The present invention relates to a multipurpose agricultural machine. More specifically it
relates to a multi-function tilling implement for ploughing, harrowing, sowing, interculturing, weeding, and harvesting.
The prior art in the area of farm implements points out many devices that can be used to ease the difficulty of each individual step, improved plows and disks for plowing, automatic seed placing machines for planting, and agri-chemical spraying mechanisms. But, few of these implements provide a means for accomplishing more than a couple of tasks at a time. The many benefits of planting crops in raised beds or rows have long been recognized. These benefits include: accelerated warming of the soil, improved drainage of the plant row area and facilitation of furrow irrigation in the plant row area. Known methods and equipment used for incorporating chemicals into these raised rows have been unsatisfactory in their precision, as well as being time consuming multiple pass processes. These processes also require that agri-chemicals be applied in a broadcast manner rather than in a more efficient band or strip. The present invention results in not only more efficient use of agri-chemicals, farm equipment, and fuel to operate the equipment; it also provides a means to save time and thereby labor. But, possibly the greatest savings that the present invention provides it to the land itself.

U.S. Pat. No. 3,815,684 discloses a minimum tillage tool comprising a "U" shaped shaper with horizontally extending blades and a planter towed behind said shaper. U.S. Pat. No. 4,838,360 discloses a minimum tillage implement employing a shaper for topping rows and a reel for tiling the area of the row. The top shaper is substantially horizontal and forward projecting to prevent dirt from spilling over the top. The reel has a number of blades evenly spaced about a shaft with tabs between the blades to allow it to roll smoothly and not clog.
U.S. Pat. No. 4,817,732 discloses a spider wheel for a rotary incorporator adapted to be towed in a given direction.
U.S. Pat. No. 4,646,850 discloses a rotary incorporator and spider wheel therefore, which has two rows of spider wheels each wheel with an individual axis of rotation. The second set of axes set at an acute angle to the first set.
U.S. Pat. No. 5,020,604 discloses a dual tillage implement with two rows of spider wheels, each spider also having an individual axis of rotation. Once again the axes of the second row are at an acute angle to the axes of the first row. US Patent No. 5267517 discloses a multi function tillage or planting implement, which can be used for leveling, planting, compacting and chemical application in single pass. The implement can be deployed in multiple gang configurations. Each gang comprises a frame for coupling the implement to a tow vehicle, a blade depending downwardly from the front of the frame for initially contacting, shaping, and leveling a raised row or bed, means for applying agri-chemicals and seed to soil behind the blade, and multiple spider gangs for vigorously mixing and incorporating agri-chemical, seed, and soil. The spider gangs comprise a first gang of rotatable spiders disposed in a row beneath said frame and journaled for rotation about a first adjustable common axis of rotation, and a second gang of rotatable spiders disposed in a row beneath said frame means and journaled for rotation about a second adjustable common axis of rotation. The first and second axes of rotation preferably form equal and opposite acute angles with respect to the implement's longitudinal axis. Preferably the second gang is partially or entirely meshed with said first gang. A roller for compacting and sealing agri-chemical and moisture in the soil trails the apparatus. It is yieldably biased downwardly from the frame behind the spider gangs into soil contact for sealing and compacting the bed.

OBJECT OF THE INVENTION
One of the objects of the present invention is to accomplish multiple functions in a single
pass. It can be combined in arrays of one or more gangs to treat soil with a minimum of
passes.
Another object of the present invention is to improve the efficiency of agri-chemicals by
providing a precise means of double incorporation, instant activation and sealing in a
single pass.
A still further object is to reduce the amount of agri-chemicals used by confining the
application of these chemicals to a predetermined band width about the planted row.
Another object of this invention is to prepare a field with the least amount of labor
possible.
A further object of the present invention is to avoid the use of more farming implements
than is absolutely necessary.
Yet another object of the present invention is to conserve expensive agri-chemicals by
limiting their application to defined rows.
An indirect object of this invention is to prevent pollution caused by run-off and
evaporation of agri-chemicals by sealing these chemicals in the soil.
A primary object of this invention is to increase the productivity of the soil by thoroughly
incorporating agri-chemicals and seeds into the soil.
DETAILED DESCRIPTION OF THE INVENTION
The equipment consists of a rectangular frame made from MS channels. The frame
mounted on a central shaft of wheels has arrangement to attach different attachments. The wheels are made of MS flat and are covered with rubber. The outer diameter of the wheel is 25 inches (63.0 cm). Therefore, in one revolution of the wheel, it covers 78 inches (200 cm) linear distance. The seed drilling attachment can be replaced with seating attachment. The output is increased by 1.5 times as compared to conventional bullock drawn seed drills (Tifan). Specially invented tyne type plough can be attached to the equipment for ploughing operation which till the land up to the depth of 6 inches (15
3

cm) and working width is 14 inches (35 cm). Thus, three plough bottoms can be attached to the equipment at a time making the working width of 105 cm. Angular back support reduces the chances of bending the plough bottom while working. The depth of ploughing can be adjusted during the ploughing operation itself.
Specially designed steel tynes can be attached to the equipment for harrowing. The working width of each tyne is 5 inches (12 cm). Thus, eight tynes can be attached at a time with the equipment making the working width of 40 inches (101 cm). There are no chances of bending the tyne while working. A special self made attachment is fitted at the rear side of the equipment which has a hand lever and cultivator. When machine moves forward it collects the uprooted stalks, weeds and crop residues. When the lever is lifted, it drops the collected material in the form of heap which is either burned or carried away manually.
The seed drilling attachment has flexibility to attach two to five furrow openers depending upon the need. Seed drilling unit gets the drive from the central shaft of the driven wheels through belt and pulley mechanism. Arrangement to vary the RPM so as to maintain plant to plant distance is incorporated in the equipment. Plant to plant distance can be adjusted from 4 to 20 inches (10 to 50 cm). Row to row distance can also be adjusted. Field capacity of this equipment is 5 to 6 acres per day whereas that of conventional bullock drawn seed drills is 3 to 4 acres per day. Equipment saves 51% of the cost involved in conventional bullock drawn seed drills.
The groundnut digging blade enters 4 to 5 inches deep in the soil to dig the groundnut plant. It cuts the roots allowing the pods to be retained along with the whole plant. The working width of the groundnut digging blade is 8 inches. It covers single row in one run. Angle of penetration for the soil-working tool can be adjusted. Mechanical lifting lever is also provided to lift the equipment at turning.
