Peanuts harvester and its harvesting method

A peanuts harvester comprising:

• a truck body;
• at least three plant row dividers, each formed as a tapered front portion and a rear portion with divergent arcuated shape and fixed on the front end of said truck body;
• at least two pairs of stalk straighteners, each including a plurality of straightening blades pivotedly mounted on a loop chain and each having a base extension to allow said blade to be horizontally backed against the chain so that two corresponding blades facing each other may straighten the stalk of peanut plant, said stalk straightener being driven by a driving unit coupled to the shaft of a peanut digger;
• at least two peanut diggers, each including a digger head operatively digging peanuts under the earth adapted for feeding peanuts into a feeder;
• a soil remover provided with soft brush coupled to the shaft of said digger to primarily remove the soil on the roots of peanut plant;
• a plant feeder including a vertical first spindle coupled to a driving motor, a right-side conveying loop having plurality of blades thereon and rotatably pushing the peanut stalks inwards in cooperation with a right-side follower spindle having plurality of blades thereon, a second spindle coupled to said first spindle and driving the right-side follower spindle, a left-side conveying loop having plurality of blades and rotatably pushing the peanut stalks inwards in cooperation with a left-side follower spindle having plurality of blades thereon, two feeding wheels rotatably engaged with each other and driven by said first spindle, and a convergent guide guiding the two-row stalks into the recess portions defined by said two feeding wheels each formed with plurality of recess portions along its perimeter;
• a tilted conveyer driven by said motor, including plurality of connecting links each having triangle-shaped side plate and every two neighboring side plates forming a recess portion, and clamping bar resiliently clamping the stalks between said bar and said recess portions between said side plates, and a stalk holder having plurality or holding blades on a conveying loop driven by said motor to quickly push the stalks forwards to be picked up by a horizontal conveyer;
• a horizontal conveyer, driven by said driving motor and adjacent to and cooperating with the upper end of said tilted conveyer, including plurality of triangle-shaped side plates on the connecting links of a chain and plurality of resilient clamps clamping the upper stalks to allow the lower peanuts to be pendant downwards;
• a peanut stripper including a casing, a driving motor, a pair of primary rakes, plural pairs of transversely-stripping rakes, and plural pairs of longitudinally-stripping rakes, all rakes resiliently held on the hubs disposed around two shafts driven by said driving motor and capable of combing and stripping the peanuts off the peanut plants when holding the upper stalks on said horizontal conveyer;
• and
• a peanut collector including a shaking screen positioned under said casing of said peanut stripper, a blower blowing air to remove the dust of peanuts when passing said screen, a collecting conveyer driven by said motor and lifting the peanuts to a collecting hopper to be finally collected in a bag.
