Description
Technical field
The utility model belongs to agricultural machinery technological field, relates to the gearshift mechanism on a kind of microtilling machine.
Background technique
On agricultural operation, often need turn over to the soil, the operation to the soil mainly is to carry out in the mode of mechanical work now, for example rotary cultivator is exactly a kind of agricultural operation machinery that early grows up.To some coupling power less rotary cultivators, be referred to as microtilling machine traditionally, these microtilling machines generally are used for the soil operation of ploughing shallowly, or in booth to the soil operation of turning over.
Generally all need to be provided with gearshift mechanism and reverse gear mechanism on the existing microtilling machine, to adapt to the different work requirement of microtilling machine.Described gearshift mechanism and reverse gear mechanism are the branch settings of coming, promptly when microtilling machine being carried out the operation of gear shift or reverse gear, need operation respectively in the different mechanism of two covers, and troublesome poeration.And two cover mechanism be provided with respectively, also seem loosely organized, install and inconvenient maintenance, be unfavorable for saving the space on the microtilling machine.
The model utility content
The purpose of this utility model is at the existing above-mentioned defective of gearshift mechanism on the existing microtilling machine, and the gearshift mechanism on a kind of novel microtilling machine is provided, and it simple in structure, compact is easy for installation and maintenance, and helps saving the space on the microtilling machine.
The purpose of this utility model can realize by following technical proposal: a kind of gearshift mechanism of microtilling machine, between the power input mechanism and power take-off mechanism of microtilling machine, comprise driving lever, gear shift fork and reverse speed fork, gear shift fork and shifting gear link, reverse speed fork and reverse gear link, shifting gear is circumferentially fixing and be socketed on the transmission shaft with gap, described reverse gear is meshed with a driven gear, after handling driving lever, described shifting gear can be meshed with driven gear and reverse gear respectively.When driving lever is stirred the gear shift fork, and when shifting gear is meshed with driven gear, shifting gear and reverse gear are separated, the power of this moment is delivered on the driven gear by shifting gear from transmission shaft, and and then be output by other driving mechanism, the driven gear of this moment is a forward rotation.And when shifting gear and transmission shaft are separated, utilize driving lever to stir reverse speed fork, and reverse gear is meshed simultaneously with shifting gear and driven gear, power on the transmission shaft is transferred on the driven gear by shifting gear, reverse gear, because reverse gear participates in the transmittance process of power, this moment, the driven gear backward rotation finally made microtilling machine retreat, and realized the reverse gear operation.
In the gearshift mechanism of this microtilling machine, described shifting gear is " worker " font, has the gearwheel and the small gear of two coaxial settings on it.
In the gearshift mechanism of this microtilling machine structure, described gearwheel and small gear are connected as a single entity.
In the gearshift mechanism of this microtilling machine, the thickness of described reverse gear is greater than the thickness of described driven gear.
In the gearshift mechanism of this microtilling machine, be provided with spline structure between described shifting gear and the transmission shaft.
Plough in the gearshift mechanism of machine in this plan, described driving lever is provided with bulb, and bulb is located in the ball cup set on the microtilling machine versatilely.
Compared with prior art, the beneficial effects of the utility model are:
Can realize the gear shift and the reverse gear operation of microtilling machine owing to only utilize a driving lever, easy and simple to handle, and gearshift mechanism and reverse gear mechanism are set at together the gearshift mechanism compact structure of this microtilling machine, be easy for installation and maintenance, help saving the space on the microtilling machine.
Description of drawings
Fig. 1 is the internal structure schematic representation of the gearshift mechanism of this microtilling machine.
Fig. 2 is the longitudinal sectional view of the gearshift mechanism of this microtilling machine.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
See Fig. 1, Fig. 2, the gearshift mechanism of the utility model microtilling machine is between the power input and output mechanism on the microtilling machine, and it is located in the gear-box 12, and structure comprises driving lever 1, gear shift fork 4, shifting gear 6, reverse speed fork 7, reverse gear 8.Gear shift fork 4 links with shifting gear 6, and reverse speed fork 7 links with reverse gear 8.Driving lever 1 can be stirred gear shift fork 4 and reverse speed fork 7, and and then drive shifting gear 6 and reverse gear 8 actions.
Shifting gear 6 is socketed on the transmission shaft 5 of being located on the gear-box 12 with gap, and transmission shaft 5 is a spline structure, and correspondingly the inside of shifting gear 6 is provided with the structure that matches with transmission shaft 5.Power source on transmission shaft 5 and the microtilling machine links.
Shifting gear 6 is " worker " font, and it has gearwheel 62 and the small gear 61 that is connected as a single entity.Shifting gear 6 also is meshed with a driven gear 9 of being located in the gear-box 12, adapts with the structure of shifting gear 6, also has the gear that two diameter differ on the driven gear 9, and they can be meshed with described gearwheel 62 and small gear 61 respectively.The thickness that toilet is stated axial distance between the large and small gear and driven gear 9 should guarantee large and small gear simultaneously with driven gear 9 engagements, like this when shifting gear 6 slides on transmission shaft 5, be meshed with driven gear 9 respectively by large and small gear, can realize the gear-change operation of microtilling machine.
Above-mentioned reverse gear 8 and driven gear 9 engagements, in order to improve the structural compactness of this gearshift mechanism, the thickness of reverse gear 8 is greater than the thickness of the gear that is engaged with on the driven gear 9.When shifting gear 6 is in neutral position, be that two gears on the shifting gear 6 are not when all being meshed with driven gear 9, stir driving lever 1, reverse gear 8 is meshed with driven gear 9 and shifting gear 6 simultaneously, and (being reverse gear 8 generally speaking is meshed with small gear 61 on the shifting gear 6, can make microtilling machine like this when reverse gear, have less speed).
