Description
Technical field
The present invention relates to a kind of rotovator, particularly native stubble cleaning rotary tiller is thrown in the chain drive of balking of a kind of nothing.
Background technology
Present stubble cleaning rotary tiller, generally by two kinds of forms, a kind of forward double-shaft stubble cleaning rotary cultivator is exactly the rotary tillage of front axle stubble-cleaning rear axle, this type of stubble cleaning rotary tiller is not only made complexity, and cost is high, and power consumption is large, fragile, easy-maintaining not, many drawbacks such as stubble-cleaning weak effect and can't using by spread.Another kind is reverse stubble cleaning rotary tiller, although the stubble-cleaning effect is better, but because the facility direction of rotation is opposite antagonism power with the power traction direction, so during operation, at first be only effective function after must overcoming resistance, so not only cause huge power consumption penalty, more easily cause machinery to damage because of rough antagonism work, thereby increased operating cost and maintenance cost.
The tillage machinery of intermediate transmission because of the corresponding lower end of middle driving box, causes the wide rotary tillage stubble-cleaning blind area of 20cm because rotary cutter can't be installed, and all can't solve this difficult problem so far.Directly affect rotary tillage stubble-cleaning and seeding quality, thus the grain yield of having influence on.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides the chain drive of balking of the nothing of a kind of reasonable in design, highly versatile, long service life to throw native stubble cleaning rotary tiller.
Technical problem to be solved by this invention is to realize by following technical scheme.The present invention is that native stubble cleaning rotary tiller is thrown in the chain drive of balking of a kind of nothing, and it comprises the chain drive box assembly, is characterized in: this chain drive box assembly adopts the mode of intermediate transmission to arrange;
The chain drive box assembly comprises transmission case body, is provided with power input shaft and driving-chain wheel shaft in the upper end of transmission case body, and power input shaft and driving-chain wheel shaft are provided with the power input gear of engagement, also is provided with the power input sprocket on the driving-chain wheel shaft; Be provided with power take-off in the bottom of transmission case body, power take-off is arranged on transmission case body by bearing and bearing enclosure seat, and power take-off is provided with power output sprocket; Power input sprocket and power output sprocket are provided with driving chain; Be provided with the chain tensioning device that is fixed on transmission case body in the outside portion of driving chain;
The two ends of described power take-off are stretched out respectively transmission case body and are connected with the shaft coupling of flanged dish, and shaft coupling is connected with the coulter shaft assembly of flanged dish by flange, is provided with dig cutter and colter on shaft coupling; The other end of coulter shaft assembly is connected with the back shaft of flanged dish by flange, and back shaft is connected on support arm by bearing and bearing enclosure seat, and support arm is connected with transmission case body by support housing.
Coulter shaft assembly of the present invention can be disclosed any coulter shaft assembly in prior art, and it generally comprises coulter shaft, and is located at the parts such as colter storehouse on coulter shaft and colter and forms.
The present invention throws in native stubble cleaning rotary tiller without the chain drive of balking: be located at power input gear on the driving-chain wheel shaft and can change in use installation site to symmetry, can realize like this counter-rotating.
Technical problem to be solved by this invention can also further realize by following technical scheme.The chain drive of balking of above-described nothing is thrown in native stubble cleaning rotary tiller: be connected in bearing on support arm and bearing enclosure seat and be provided with lubricant reservoir, also be provided with the pouring orifice that is communicated with lubricant reservoir on bearing and bearing enclosure seat.Charging-up lubricant oil, increase service life so easily.
Technical problem to be solved by this invention can also further realize by following technical scheme.Above-described nothing is balked in the native stubble cleaning rotary tiller of chain drive throwing: be provided with the fence type cover plate above the coulter shaft assembly.The fence type cover plate can be contained on the support of rotovator when mounted, perhaps is fixed on support arm or intermediate transmission casing by support.The present invention passes through to throw cubic metre of earth fence type cover plate to the simple and easy setting of increase at rotary blade, utilizes the native inertia of throwing to complete and follows bad hack, gear grass, the series of complex farm works such as the native stubble-cleaning of throwing.
Technical problem to be solved by this invention can also further realize by following technical scheme.Above-described nothing is balked in the native stubble cleaning rotary tiller of chain drive throwing: described fence type cover plate is arcuation.
Technical problem to be solved by this invention can also further realize by following technical scheme.Above-described nothing is balked in the native stubble cleaning rotary tiller of chain drive throwing: described chain tensioning device comprises spring forked standard and the leaf spring that is fixed on transmission case body, be provided with adjusting bolt on the spring forked standard, adjusting bolt is provided with and cap, be fixed with spring on adjusting bolt in the spring forked standard, described leaf spring is between driving chain and spring.Chain tensioning device elasticity disclosed by the invention is high, and tensioner is effective.The present invention also can use disclose in prior art any applicable to chain tensioning device of the present invention.
The present invention easily causes chain breakage without the various tillage machineries that the native stubble cleaning rotary tiller of chain drive throwing of balking has thoroughly solved the large coordinated with agricultural machinery of large horse, damages bearing, and gear even breaks the seriously generations of mechanical breakdown problems such as transmission case assembly.The cutter of digging of setting of the present invention can first be dug the immature soil of aforementioned blind area, carry out fragmentation by colter set on shaft coupling again, solved especially the tillage machinery of intermediate transmission because of lower end corresponding to middle driving box, because of this insurmountable difficult problem so far of the 20cm rotary tillage stubble-cleaning blind area that can't install that rotary cutter causes.
The present invention is due to the high-test chain kind of drive that has adopted with the chain swelling device, thoroughly solved the not parallel rigid apical tooth that can't precise positioning causes because of the centre-to-centre spacing between the gear drive transmission of having a contest, thereby cause gear, bearing, the generation of the catastrophe failures such as the parts such as transmission case heating fatigue damage.
Compared with prior art, the present invention makes simply, produces easily, and cost is low, and highly versatile, and is easy to maintenance.Rotovator of the present invention is compared with traditional stubble cleaning rotary tiller, can be energy-conservation more than 50%, and the rotary tillage stubble-cleaning effect doubles the left and right.And, because adopting flange, the coulter shaft assembly connects, and not only easy to maintenance, and saved greatly the cost of maintenance.
