Abstract
The invention relates to a drift-angle rotation transmission mechanism for a key groove and a planetary cylindrical pin. The drift-angle rotation transmission mechanism comprises a power transmission shaft, a spline cutter shaft, the planetary cylindrical pin and a rotary cutter head; the two ends of the power transmission shaft are connected with a central transmission box and the spline cutter shaft respectively; the spline groove is formed in the spline cutter shaft; one end of the planetary cylindrical pin can be arranged in the spline groove in a swinging mode, and can swing in the spline groove by an angle of 2a; the other end of the planetary cylindrical pin is fixedly arranged on the rotary cutter head; and a drift angle of a is provided in a perpendicular direction between the rotary cutter head and the spline cutter shaft. The drift-angle rotation transmission mechanism is labor-saving to operate, novel in design and simple and reliable in transmission; the planetary cylinder pin in the spline groove of the spline cutter shaft is driven to swing, so that drift-angle rotation of the rotary cutter head is realized, and therefore, a rotary-cutting coulter cuts off a soil layer below the central transmission box, and the problem of central balk of a central transmission type rotary cultivator is solved; and the drift-angle rotation transmission mechanism has an extremely high practical and popularization value, and promotes quick development of ecological agriculture very well.
Description
Technical field
The invention belongs to agricultural machinery technological field, particularly relate to a kind of keyway and planetary cylindrical pin drift angle rotating actuator.
Background technology
Side driving rotary cultivator, its drive path is long and tortuous, and complex structure, cutter shaft two ends moment of torsion differs greatly, the unfavorable operation of deviation of gravity center unit centre line and balance.The features such as and tiller with central gearing has structure simply, center is placed in the middle, and cutter shaft two ends moment of torsion is balanced, thus obtain a large amount of promoting the use of in China.But central transmission rotovator, intermediate drive gear case is positioned at farming central authorities, the existing cutter tooth of soil layer of the transverse width occupied by it cannot be ploughed and remove, in addition extensively straw-returning is promoted now, deeply revolve the ecological agriculture of burying stubble, central tooth roller box position harmony soil twines careless phenomenon more seriously, greatly have impact on operation quality, cause central transmission rotovator in the popularization of straw-returning technology, cannot a large amount of popularizations and utilization be carried out.
Summary of the invention
The present invention seeks to provide a kind of can solve tiller with central gearing central authorities' keyway of balking and planetary cylindrical pin drift angle rotating actuator to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution used in the present invention is: a kind of keyway and planetary cylindrical pin drift angle rotating actuator, comprise power transmission shaft, spline cutter shaft, planetary cylindrical pin and rotary head; Described power transmission shaft two ends are connected with spline cutter shaft with central gearing box respectively; Spline is provided with in described spline cutter shaft; Swingable being arranged in spline in described planetary cylindrical pin one end, and make 2a angular oscillatory motion within it; The described planetary cylindrical pin other end is installed on rotary head; There is between the vertical direction of described rotary head and spline cutter shaft a angle angle of eccentricity.
Preferably, the scope at described a angle is 3 °-15 °.
Preferably, described rotary head is symmetric about the central gearing box both sides of rotovator.
Preferably, also hermetic oil seal is provided with between described spline cutter shaft and rotary head.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages: the keyway of the present invention program and planetary cylindrical pin drift angle rotating actuator, its rapid operation, modern design and transmission is simple and reliable, swing by driving the planetary cylindrical pin in strong groove of spending of spline cutter shaft, thus the drift angle realizing rotary head rotates, soil layer under making rotary-cut colter excise central gearing box, solve the problem that tiller with central gearing central authorities balk, there is high practical and popularizing value, well promoted the fast development of the ecological agriculture.

Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Of the present invention a kind of keyway as shown in accompanying drawing 1-2 and planetary cylindrical pin drift angle rotating actuator, comprise power transmission shaft 1, spline cutter shaft 2, planetary cylindrical pin 3 and rotary head 4; Described power transmission shaft 1 two ends are connected with spline cutter shaft 2 with central gearing box (not shown) respectively; Spline 5 is provided with in described spline cutter shaft 2; Swingable being arranged in spline 5 in described planetary cylindrical pin 3 one end, and make 2a angular oscillatory motion within it; The other end of described planetary cylindrical pin 3 is installed on rotary head 4; There is between described rotary head 4 and the vertical direction of spline cutter shaft 2 a angle angle of eccentricity; Swingable being arranged in spline in described planetary cylindrical pin one end, and make 2a angular oscillatory motion within it; The scope at described a angle is 3 °-15 °; Described rotary head 4 is symmetric about the central gearing box both sides of rotovator; Hermetic oil seal 6 is also provided with between described spline cutter shaft 2 and rotary head 4.
Of the present invention a kind of keyway as shown in accompanying drawing 1-2 and planetary cylindrical pin drift angle rotating actuator, before actual use, attach it on tiller with central gearing, and power transmission shaft be connected with the central gearing box of tiller with central gearing, when tiller with central gearing works, power is passed to power transmission shaft by central gearing box by it, then power is sent to the spline cutter shaft be mated by power transmission shaft, then power drive carries out 2a angular oscillatory motion at the planetary cylindrical pin in strong groove of spending of spline cutter shaft, and planetary cylindrical pin is fixed on and has on the rotary head of a angle angle of eccentricity with the vertical direction of spline cutter shaft, thus the drift angle realizing rotary head rotates, and drive the rotary-cut colter be arranged on rotary head also to do drift angle rotation, achieve rotary-cut colter and get out of the way central driver gear case above spline cutter shaft, to the lower soil layer that can excise under central driver gear case, meet agricultural demand.
Further, have hermetic oil seal between spline cutter shaft and swivel knife shaft, its Main Function is the leakage preventing lubricating oil.
Further, when the scope at a angle is 3 °-15 °, it excises best results.
Keyway of the present invention and planetary cylindrical pin drift angle rotating actuator, its rapid operation, modern design and transmission is simple and reliable, swing by driving the planetary cylindrical pin in strong groove of spending on spline cutter shaft, thus the drift angle realizing rotary head rotates, soil layer under making rotary-cut colter excise central gearing box, solve the problem that tiller with central gearing central authorities balk, there is high practical and popularizing value, well promoted the fast development of the ecological agriculture.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
