Description
Technical field
The utility model belongs to the technical field of agricultural machinery, specifically is meant a kind of deviator that is used for crops results back chopping and returning machinery.
Background technology
At present, to carry out the chopping and returning operation to cane, the root stubble of crops after the crops results, it is that one-directional rotation is carried out chopping and returning that the existing characteristics that are used for the field-returning machine of crushed stalk are pulverized rotating shaft, the main defective that exists is that crushed stalk is not thorough, stalk fibre can't cut, stalk winding cutter choking phenomenon is serious, thereby power is required high, inefficiency.Therefore, provide a kind of crops crushing and returning to field machine that is applicable to, become the industry technical issues that need to address with the deviator of increasing work efficiency.
The utility model content
The purpose of this utility model is to provide a kind of forward and reverse rotation operation of crushing shaft of controlled crops crushing and returning to field machine, thus the deviator of increasing work efficiency.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: crops crushing and returning to field machine deviator, comprise casing, casing is provided with power shaft and output shaft, power shaft is vertical with output shaft to be provided with, spacer sleeve is provided with two rotatable bevel gear wheels on the power shaft, the tooth of these two bevel gear wheels is relative, output shaft the inner is provided with the bevel pinion that is meshed with two bevel gear wheels respectively, power shaft is provided with combination gear in axial sliding on the shaft part between two bevel gear wheels, be provided with in the casing and can drive the shift fork that combination gear slides and engages with two bevel gear wheels with respectively on power shaft, casing is provided with the break-in control lever that is connected with shift fork outward.
Described casing is provided with lubricating oil inlet and oil drain out.
Be provided with bearing between described bevel gear wheel and the power shaft.
Owing to adopted above-mentioned structure, the utility model is by break-in control lever shift fork, shift fork drives combination gear and slides on power shaft to engage with two bevel gear wheels respectively, can switch separately and the power shaft interlock by two bevel gear wheels like this, bevel gear wheel rotates and can drive the bevel pinion rotation, rotate thereby drive output shaft, thereby realize the break-in operation.The utility model is simple in structure, compact, and is easy to operate, has very strong practicality and promotional value, can be widely used in to carry out the break-in operation on the crops crushing and returning to field machine.
Description of drawings
Fig. 1 is the structural representation of crops crushing and returning to field machine deviator.
Fig. 2 is the cutaway view along B-B line among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, crops crushing and returning to field machine deviator described in the utility model comprises casing 1, and described casing 1 is provided with lubricating oil inlet and oil drain out, is convenient to inject lubricating oil like this and is lubricated.Described casing 1 is provided with power shaft 2 and output shaft 3, power shaft 2 and output shaft 3 vertical settings, and power shaft 2 is connected with power set, and output shaft 3 is connected with the crushing shaft of field-returning machine.Spacer sleeve is provided with two rotatable bevel gear wheels 4 on the described power shaft 2, and the tooth of these two bevel gear wheels 4 is relative.Be provided with bearing 9 between described bevel gear wheel 4 and the power shaft 2.Described output shaft 3 the inners are provided with 5, two bevel gear wheels 4 of bevel pinion that are meshed with two bevel gear wheels 4 respectively and are meshed with bevel pinion 5, and bevel gear wheel 4 rotates and can drive bevel pinion 5 rotations, rotates thereby drive output shaft 3.Power shaft 2 is provided with combination gear 6 in axial sliding on the shaft part between two bevel gear wheels 4, combination gear 6 can be spline fitted with power shaft 2, and combination gear 6 can slide relatively with power shaft 2, but can not relatively rotate.Be provided with in the described casing 1 and can drive the shift fork 7 that combination gear 6 slides and engages with two bevel gear wheels 4 with respectively on power shaft 2, the casing 1 outer break-in control lever 8 that is connected with shift fork 7 that is provided with.By break-in control lever 8 shift forks 7, shift fork 7 drives combination gear 6 and slides on power shaft 2 to engage with two bevel gear wheels 4 respectively, can switch and power shaft 2 interlocks by two bevel gear wheels 4 like this, thereby realizes the break-in operation.
Farming industry crushing and returning to field machine described in the utility model is after the crops results, can but the crushing shaft both forward and reverse directions be changeed by manual break-in shelves at different crops break-in gearbox revolves, pulverize as banana class root stubble is long and fiber more than crops the time manual break-in shelves by deviator will pull out to bar steering power output shaft one end and make the crushing shaft forward rotation, being located at blade forward rotation on the crushing shaft directly smashs to pieces with ground surface and abandons and the field can thoroughly solve the traditional mechanical pulverized fiber like this and can't cut, twines the serious problem of cutter choking phenomenon.And be rotated in the forward the direction of advance unanimity of direction tractor, from actual state of cultivation as seen, crushing shaft is just being changed a job and can equably the bar stem of banana pulverized throwing backward when doing, and increases the onward impulse effect to tractor simultaneously, play and alleviate the tractor load, oppositely pulverize fuel-efficient.Pulverize as pineapple, corn rhizome during than crops such as short fibre content are less the manual break-in shelves by deviator will pull out to the bar steering power output shaft other end and make the crushing shaft backward rotation, the blade backward rotation that is located on the crushing shaft is interior with the crops chopping and returning by hood.
In a word; though the utility model has exemplified above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
