Description
Technical field
This utility model belongs to agricultural machinery technological field, particularly relates to a kind of keyway and planetary cylindrical pin drift angle rotating actuator.
Background technology
Side driving rotary cultivator, its drive path length and tortuous, structure complexity, cutter shaft two ends moment of torsion differs greatly, the unfavorable operation of deviation of gravity center unit centre line and balance.And tiller with central gearing has simple in construction, the features such as center is placed in the middle, the moment of torsion equilibrium of cutter shaft two ends, thus obtained substantial amounts of promoting the use of in China.But central transmission rotary cultivator, intermediate drive gear case is positioned at farming central authorities, the existing cutter tooth of soil layer of the transverse width that it is occupied cannot be ploughed and remove, the most now it is widely popularized straw-returning, the ecological agriculture of stubble is buried in deep rotation, and central tooth roller box position harmony soil twines grass phenomenon more seriously, leverages operation quality, cause central transmission rotary cultivator in the popularization of straw-returning technology, it is impossible to carry out substantial amounts of popularization and utilization.
Utility model content
This utility model purpose is to provide a kind of to solve, in order to overcome the deficiencies in the prior art, keyway and the planetary cylindrical pin drift angle rotating actuator that tiller with central gearing central authorities balk.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of keyway and planetary cylindrical pin drift angle rotating actuator, including power transmission shaft, spline cutter shaft, planetary cylindrical pin and rotary head；Described power transmission shaft two ends are connected with central gearing box and spline cutter shaft respectively；It is provided with spline in described spline cutter shaft；Swingable being arranged in spline in described planetary cylindrical pin one end, and within it make 2a angular oscillatory motion；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, described a angle is in the range of 3 °-15 °.
Preferably, described rotary head is symmetric about the central gearing box both sides of rotary cultivator.
Preferably, it is additionally provided with hermetic oil seal between described spline cutter shaft and rotary head.
Utilization due to technique scheme, this utility model compared with prior art has the advantage that keyway and the planetary cylindrical pin drift angle rotating actuator of this utility model scheme, its rapid operation, modern design and transmission are simple and reliable, by driving the planetary cylindrical pin in strong groove of spending of spline cutter shaft to swing, thus the drift angle realizing rotary head rotates, make the soil layer under rotary-cut colter excision central gearing box, solve the problem that tiller with central gearing central authorities balk, there is high practical and popularizing value, well promote the fast development of the ecological agriculture.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solutions of the utility model are described further.
Accompanying drawing 1 is the structural representation of keyway of the present utility model and planetary cylindrical pin drift angle rotating actuator.
Accompanying drawing 2 is the partial enlarged drawing of accompanying drawing 1.
Wherein: 1, power transmission shaft；2, spline cutter shaft；3, planetary cylindrical pin；4, rotary head；5, spline；6, hermetic oil seal.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Described in the utility model a kind of keyway as shown in accompanying drawing 1-2 and planetary cylindrical pin drift angle rotating actuator, including 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 central gearing box (not shown) and spline cutter shaft 2 respectively；It is provided with spline 5 in described spline cutter shaft 2；Swingable being arranged in spline 5 in described planetary cylindrical pin 3 one end, and within it make 2a angular oscillatory motion；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 within it make 2a angular oscillatory motion；Described a angle is in the range of 3 °-15 °；Described rotary head 4 is symmetric about the central gearing box both sides of rotary cultivator；It is additionally provided with hermetic oil seal 6 between described spline cutter shaft 2 and rotary head 4.
Described in the utility model a kind of keyway as shown in accompanying drawing 1-2 and planetary cylindrical pin drift angle rotating actuator, actually used before, 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 coordinated with it 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 the vertical direction with spline cutter shaft and has on the rotary head of a angle angle of eccentricity, thus the drift angle realizing rotary head rotates, and drive the rotary-cut colter being arranged on rotary head also to make drift angle rotation, achieve rotary-cut colter above spline cutter shaft, get out of the way central driver gear case, to the lower soil layer that can excise under central driver gear case, meet agricultural demand.
Further, having hermetic oil seal between spline cutter shaft and swivel knife shaft, its Main Function is the leakage preventing lubricating oil.
Further, when a angle is in the range of 3 °-15 °, it excises best results.
Keyway of the present utility model and planetary cylindrical pin drift angle rotating actuator, its rapid operation, modern design and transmission are simple and reliable, by driving the planetary cylindrical pin in strong groove of spending on spline cutter shaft to swing, thus the drift angle realizing rotary head rotates, make the soil layer under rotary-cut colter excision 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 it is only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, within the scope of all falling within this utility model rights protection.
