Summary of the invention
The purpose of this utility model provide a kind of can with low-power supporting, no straw root in low, the high efficiency of cost and the post-job field, do not gather around the stalk cutter of soil when plowing.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is that this stalk cutter comprises casing, is arranged on transmission device in the casing and the shredding mechanism that is connected with transmission device, it is characterized in that: described shredding mechanism comprises left-handed tool arm and the dextrorotation tool arm that position correspondence, rotation direction are opposite and is separately positioned on the left and right knife section that revolves on the tool arm, comprises also that cutting edge is arranged on downwards left and rightly to revolve between the tool arm and can form ledger-plate to cutting with knife section.
The shape of described left-handed tool arm and dextrorotation tool arm is a falcate, and its crooked direction is identical with the direction of its rotation, and the shape of knife section is corresponding with the left and right curved shape that revolves tool arm; The blade of knife section and ledger-plate is a zigzag.
The described counterrotating left and right tool arm that revolves is two groups, and described transmission device comprises driving wheel, reverse wheel and power output wheel, and the driving wheel reverse wheel by every group respectively is connected with its power output wheel.
Casing is provided with suspension holdfast, and suspension holdfast is provided with land wheel.
The left and right tool arm that revolves is connected by spline, bayonet lock and the nut outer end with the power output wheel axle, and with fixing on left and right revolving on the tool arm, ledger-plate is fixed on lower box and the left and right corresponding position of tool arm of revolving by screw to knife section by screw; Driving wheel is connected with wheel shaft by key with power output wheel, and its wheel shaft is connected with casing by bearing; The wheel shaft of reverse wheel is contained on the casing, and its axle head is provided with draw-in groove, and check plate is stuck in the draw-in groove and by screw and is fixed on the casing; Reverse wheel is connected with wheel shaft by bearing.
Casing is provided with case lid, is provided with end cap at the axle head of drive sprocket axle and power output wheel axle, and end cap is fixed on the casing by screw, also is provided with sealing gasket between case lid and casing, end cap and wheel shaft.
Because shredding mechanism is set to the left and right sides counterrotating tulwar shape cutting knife, and is provided with stationary knife between two tulwars, stalk can be blocked between two tool arms at an easy rate cuts off, during operation, tulwar screw in underground 3 centimeters dark, can be resected to root.The mode of this rotational shear needs power little, compares with the straw cutting apparatus that existing big-powered tractor drives, and processing crop of the same area in the identical time, required drive only is its half, therefore, can improve effect more than one times.Stalk after this machined is 6～8 a centimeters long circle section, can roll into ditch dug with a plow automatically when plowing, and can not cause and gather around soil.The utility model can be carried out straw-returning to multiple long-stalked crop such as corn, cotton, uses mating power little, is suitable at small size farmland operations such as mountain areas, and is beneficial to the existing peasant's machine of peasant household's utilization as mating power, for the peasant has saved great amount of investment.
