Abstract
The utility model discloses a changeover speed gear for walking agricultural equipments, which is provided with a power input end, wherein a drive gear on the power input end is firstly connected with a reversing apparatus, and on the reversing apparatus, two driven gears with the same specification respectively form rotating installment relatively to a plain shaft, the middle section of the plain shaft is a spline shaft, a shifting fork and the spline shaft are in axial moving installment, the extending end of the plain shaft is fixedly connected with a primary speed transforming gear, the drive gear and the two driven gears which can be meshed with the drive gear are bevel gears, the inner sides of the two driven gears are respectively fixed with a semi-jaw clutch, and two ends of the shifting fork are respectively provided with semi-jaw clutches. The changeover speed gear for walking agricultural equipments can realize serving bidirectional multipurpose and can be used in military machinery.
Description
Technical field
The utility model relates to the gearbox of agricultural machinery and implement, directly relates to the gearbox of the agricultural machinery and implement of the operation of can walking.
Background technique
Tractor and combine-harvester all belong to the agricultural machinery and implement of the class of walking, and all are in walking states during work, yet because the job specification difference, the direction of travel during the two work is opposite fully again.Steamboat is more convenient for handling preceding during tractor work; Bull wheel is more convenient for handling preceding during combine-harvester work.As farm machinery, the unification of function has limited the development of himself again, particularly, only can use tens days all the year round as these class agricultural machinery and implement of combine-harvester, even cross-regional operation, one month at most only.Though the more specialized design of agricultural machinery and implement can improve performance to a certain extent, yet too professional equipment also can influence the popularization of agricultural machinery and implement.Especially in the lower zone of intensive cropping degree, the peasant of unshared housing is difficult to bear and spends big price to buy the very high equipment of degree of specialization.
Summary of the invention
The purpose of this utility model will provide a kind of improved gear box for walking agricultural implement exactly, when it is installed in when using on the walking agricultural implement, can overcome the problem of existing walking agricultural implement function singleness effectively.
The purpose of this utility model is achieved in that gear box for walking agricultural implement, has power intake, driving gear on the described power intake at first inserts commutator, on described commutator, two each self-formings of driven gear of same specification are installed with respect to the rotation of optical axis, the intermediate section of optical axis is the key axle, shift fork and key axle form and can axially movablely install, the external part of optical axis connects firmly an elementary speed change gear, described driving gear and two driven gears that can mesh with it are bevel gear, the inboard of two driven gears is fixed half jaw clutch separately, and the two ends of shift fork also respectively are set to half jaw clutch.
As further scheme of the present utility model be: the number of teeth on the tooth indention of half jaw clutch, every half jaw clutch is 2-6.
As further scheme of the present utility model be: the number of teeth on every half jaw clutch is 2-3.
The utility model is owing at first inserted commutator at power intake, thereby when the utility model is installed on the walking agricultural implement, can obtain to advance and the speed that retreats same class, that is during the walking of this agricultural machinery and implement no matter steamboat at preceding still bull wheel preceding, can both adjust the high, medium and low shelves speed that needs easily.When steamboat can directly use as tractor when preceding; When bull wheel when preceding, after corresponding establishment is installed, can be used as combine-harvester and use.According to the difference of farmland seasonal variations or workplace, adopt the agricultural machinery and implement behind the utility model can select the headstock direction arbitrarily, and can advance, retreat or the three kinds of states that berth under finish the farm work of regulation, two-way use of the machine of realizing respectively more.The utility model also can be used for military machinery.
Description of drawings
Accompanying drawing is a structure principle chart of the present utility model, and the utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
Accompanying drawing shows the structure of the utility model gear box for walking agricultural implement, inserts commutator between power intake 1 and elementary speed change gear 7.Two driven gears 4 that are driving gear 2 and same specification on the power intake 1 mesh simultaneously, every driven gear 4 is installed with respect to the rotation of optical axis 5 by each self-forming of bearing, the intermediate section of optical axis 5 is a key axle 6, shift fork 3 forms and can axially movablely install with key axle 6, the external part of optical axis 5 connects firmly an elementary speed change gear 7, driving gear 2 and two driven gears 4 that can mesh with it are bevel gear, the inboard of two driven gears 4 is fixed half jaw clutch 8 separately, the two ends of shift fork 3 also respectively are set to half jaw clutch 8, the tooth of half jaw clutch 8 preferentially adopts zigzag fashion, the number of teeth on every half jaw clutch 8 is 2-6, preferred 2-3.
Working procedure of the present utility model is: when the driving gear on the power intake 12 and two driven gear 4 engagements, two driven gears 4 dally in position with respect to optical axis 5; When shift fork 3 moves to left, half jaw clutch 8 on the left end driven gear 4 meshes with half jaw clutch 8 of shift fork 3 left ends, drive elementary speed change gear 7 by key axle 6, optical axis 5, thereby the rotation of following stages gear in the drive gearbox, and power sends out the most at last, realizes the transmission of a direction; When shift fork 3 moves to right, can realize outside outputting power under another direction drive state.
After the utility model was installed on the walking agricultural implement, original facility that reverses gear no longer needed to be provided with.
Claims (3)
1, a kind of gear box for walking agricultural implement, has power intake (1), it is characterized in that: the driving gear (2) on the described power intake (1) at first inserts commutator, on described commutator, each self-forming of two driven gears (4) of same specification is installed with respect to the rotation of optical axis (5), the intermediate section of optical axis (5) is key axle (6), shift fork (3) forms and can axially movablely install with key axle (6), the external part of optical axis (5) connects firmly an elementary speed change gear (7), described driving gear (2) and two driven gears (4) that can mesh with it are bevel gear, the inboard of two driven gears (4) is fixed half jaw clutch (8) separately, and the two ends of shift fork (3) also respectively are set to half jaw clutch (8).
