Abstract
The utility model relates to a kind of high-strength rotary blade, its structure comprises handle of a knife and blade, described blade comprises side tangent plane and Sidelong portion, described Sidelong portion is positioned at the front portion of described side tangent plane, and bend to the side arc of described side tangent plane, bottom the leading portion of described side tangent plane and the bottom welding of described Sidelong portion have continuous print diamond knife edge, the side cutting blade retained bottom one end of described diamond knife edge and described side tangent plane is connected smoothly.The utility model improves its rigidity of rotary blade cutting edge portion and the breaking strength to the hard object in soil, in the rotovator course of work, when encountering the hard object such as the stone in soil, fragment of brick when rotary blade, hard object can be smashed or open, thus avoid the generation of tipping phenomenon and the damage to rotary blade, rotovator can be made to keep normal rotary tillage process.Cutting edge strength of the present utility model is large, and long service life, is particularly suitable for installing and using on heavy horizontal shaft type rotovator.
Description
Technical field
The utility model relates to a kind of agricultural tool, the high-strength rotary blade of the one specifically installed and used on rotovator.
Background technology
Rotovator completes cultivated, to harrow operation cultivation machinery.Because of its have hack ability strong, plough after the features such as earth's surface is smooth, thus obtain and apply comparatively widely.Meanwhile, rotovator can also shred the crop root stubble being embedded in below earth's surface, is convenient to the subsequent job of sower, for later stage sowing provides good kind bed.In addition, rotovator also has stronger hack ability, and one-stop operation can make soil in small, broken bits, and evenly, Land leveling, reaches the requirement that nonirrigated farmland is sowed or paddy field is planted, be conducive to striving for farming season, improves work efficiency in clay fertilizer blending.
The workpiece of rotovator mainly comprises rotary tillage rotor and by some Rotary tillage blades that bull helical evenly configures, passes through actuator drives by tractor motive power output shaft.The direction of rotation of rotor is usually consistent with the direction that tractor wheels is rotated.Rotary tillage blade cuts soil layer by after forward direction, and is thrown rearwardly and upwardly on case and planker by soil block, makes it further fragmentation.Rotary tillage blade can be divided into scalpriform cutter, tulwar, right angle cutter and curved knife etc.Scalpriform cutter front end is narrower, and have ability of burying preferably, energy ezpenditure is little, but easily twines grass, is used for the few vegetable garden of weeds and garden.The curved cutting edge of tulwar has Sliding cutting action, easily cuts off grass roots and straw winding, is suitable for paddy field farming.Right angle cutter has vertical cutting blade and horizontal cutting blade, and blade is wider, good rigidly, easily manufactures, but penetration performance is poor.The intensity of curved knife is large, and good rigidly, Sliding cutting action is good, is generally used on heavy-duty rotary tillage machine.Heavy horizontal shaft type rotovator has stronger hack ability, is used for opening up wasteland shrub ground, marshland and ground, farmland running to weeds.
Existing rotary blade, according to the difference of its Sidelong portion along the bending direction of side tangent plane, is divided into left tulwar and right tulwar.In the course of work of rotovator, if when rotary blade encounters the hard object such as stone, fragment of brick in soil, because the rotating speed of rotary blade is very fast, very easily there is tipping phenomenon, cause the damage of rotary blade, and affect the rotary tillage process of rotovator.
Utility model content
The purpose of this utility model is just to provide a kind of high-strength rotary blade, easily occurs the problem that tipping damages to solve rotary blade after touching hard object.
The utility model is achieved in that a kind of high-strength rotary blade, comprise handle of a knife and blade, described blade comprises side tangent plane and Sidelong portion, described Sidelong portion is positioned at the front portion of described side tangent plane, and bend to the side arc of described side tangent plane, bottom the leading portion of described side tangent plane and the bottom welding of described Sidelong portion have continuous print diamond knife edge, the side cutting blade retained bottom one end of described diamond knife edge and described side tangent plane is connected smoothly.
Bending angle between described Sidelong portion and described side tangent plane is 125 °-135 °.
After described Sidelong portion bending, its knife back portion is towards overbending direction squint.
The utility model installs diamond knife edge additional by local on rotary blade, improve its rigidity of rotary blade cutting edge portion and the breaking strength to hard object, in the rotovator course of work, when encountering the hard object such as the stone in soil, fragment of brick when rotary blade, hard object can be smashed or open, avoid the generation of tipping phenomenon and the damage of rotary blade, rotovator can be made to keep normal rotary tillage process.
Cutting edge strength of the present utility model is large, and long service life, is particularly suitable for installing and using on heavy horizontal shaft type rotovator.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises handle of a knife 1 and blade, blade comprises straight side tangent plane 2 and bending Sidelong portion 3, Sidelong portion 3 is positioned at the front portion of side tangent plane 2, and bend (Fig. 2) to the side arc of side tangent plane 2, bottom the leading portion of side tangent plane 2 and the bottom welding of Sidelong portion 3 have continuous print diamond knife edge 5, the side cutting blade 4 retained bottom one end of diamond knife edge 5 and side tangent plane is connected smoothly.
In Fig. 2, the bending angle β between the Sidelong portion 3 of rotary blade and side tangent plane 2 is 125 °-135 °.After Sidelong portion 3 bends, can there be suitable squint in its knife back portion towards overbending direction, namely relative to the knife back at top, outside tulwar, (i.e. the convex surface of circular arc) can with suitable inclination along its width for Sidelong portion 3, its effect is when rotary blade screws in soil layer from space, along with rotation moves ahead, Sidelong portion 3 contacts in vertical state with upper soll layer, and this state is buried the most laborsaving, can reach the best to the crushing effect of hard object.
Claims (3)
1. a high-strength rotary blade, comprise handle of a knife and blade, described blade comprises side tangent plane and Sidelong portion, described Sidelong portion is positioned at the front portion of described side tangent plane, and bend to the side arc of described side tangent plane, it is characterized in that, bottom the leading portion of described side tangent plane and the bottom welding of described Sidelong portion have continuous print diamond knife edge, the side cutting blade retained bottom one end of described diamond knife edge and described side tangent plane is connected smoothly.
2. high-strength rotary blade according to claim 1, is characterized in that, the bending angle between described Sidelong portion and described side tangent plane is 125 °-135 °.
