Multipurpose farming and gardening machine

A multipurpose agricultural machine, wherein said machine comprising:

• (a) an auger assembly positioned inside an outer housing comprising:
• at least three rotary soil excavating augers (7) configured to rotate to rake and remove soil;
• at least one deflector plate (6);
• (b) a composite flange assembly comprising:
• (i) at least one top flange mounted on a central axial shaft;
• and
• (ii) at least one bottom flange mounted on the central axial shaft;
• (iii) the axial shaft mounted on bearings on the top and bottom cover at either end of the machine housing, with such axial shaft also passing though a bush on the top and bottom cover end, beside the bearing block to permit axial movement of the shaft, capable of pushing the assembly downward or upward
• (iv) a rotary drive which engages to operate a piston type linear actuator or a screw rod with nut arrangement to which the central axial shaft with composite flange and auger drive assembly is coupled, so as to push the axial shaft and assemblies with the augers to dig into the soil or to reverse and retrieve it
• (v) plurality of auger shafts sliding within the flange assembly, in communication with the rotary soil excavating augers (7);
• (vi) at least three spring mounted outer blocks with spring loaded sliding bearing mounts to hold one end of the three outer auger shafts on the bottom surface of the top flange;
• (vii) at least three spring mounted outer blocks with spring loaded sliding bearing mounts to hold the other end of the three outer auger shafts on the bottom surface of the bottom flange;
• (viii) at least three inner blocks with radially sliding bearing mounts to hold one end of the three inner auger shafts on the top surface of the top flange;
• (ix) at least three inner blocks with radially sliding bearing mounts to hold the other end of the inner auger shafts on the top surface of the bottom flange;
• (x) radial guides and slots (12) for the auger shafts seated on bearings in their mounts, on all the inner and outer blocks, to enable them move inward or outward within such blocks
• (xi) spring loading of bearing mounts on the three outer blocks, for ease of retraction to reverse inward movement
• (xii) involute guideway slots (16) on the top and bottom flange, in which the auger shafts get guided with the operation of a lever, to enable bring the augers towards each other or move them outward
• (xiii) at least one lever configured to effect radial inward or radial outward movement of the auger shafts with respect to the central shaft axis;
• (xiv) a screw at the end of the lever for effecting transverse movement, with a fastening nut holding wheel to lock the flange assembly to the housing once adjustment of the distances between the augers are done or alternatively a ratchet and pawl mechanism for unidirectional movement, lock or release, as may be required to arrest and lock the transverse movement for changes to the distance between the augers
• wherein the rotary soil excavating augers (7) are connected with plurality of sleeves and plurality of bolts on to either, three pairs of inner blocks or three pairs of outer blocks and such inner and outer blocks are arranged along a radial direction on the two flanges with the lever;
• (c) an auger drive arrangement within the flange assembly as in (b) above positioned inside the machine housing comprising:
• (i) at least three chain driven sprocket wheel pinions, mounted on the inner three auger shafts held at either end, on the bearings within the three sliding bearing mounts, within the inner blocks, on the top surface of both the flanges and
• (ii) at least three chain driven sprocket wheel pinions, mounted on the outer three auger shafts held at either end on bearings within the three spring mounted sliding bearing mounts, within the outer blocks, on the bottom surface of both the flanges;
• (iii) a chain weaving on the outer surface of the sprocket wheels on the three outer auger shafts and along the inner surface of the sprocket wheels on the three inner auger shafts
• (iv) a motor positioned in the axial direction of the flange assembly, coupled and driving one of the auger shafts between the outer blocks;
• wherein the auger drive arrangement and flange assembly is mounted on a hand operated trolley and comprises a linear actuator (2) or screw rod/nut assembly arrangement is driven by a motor is coupled to drive the central axial shaft and is positioned in the axial direction of the flange assembly with the rotary soil excavating augers (7) configured to drive the augers (7) into the soil or retract them from out of the soil.
