Description
Technical field
The utility model relates to the preceding Biodge device of trac., especially a kind of preceding Biodge device of adjusting crack, trac. ground and wheelspan.
Background technology
Since wheel-tire tractor was born, the two-wheel drive trac. is the leading position in occupation of market basically, and is able to use widely; But, in recent years because greatly developing of four-wheel drive tractor progressively weakened the market leading position of two-wheel tractor.Though four-wheel drive tractor has multiple preceence, price is high, investment is big, makes the domestic consumer of various small scale-farms or single type be not easy to bear, accept, and is difficult to generally apply.And the two-wheel drive trac. has self more superior economy, and price is low, makes it under the less demanding situation of functions of use, still has certain market demand.
Yet the two-wheel drive trac. mainly is by trailing wheel propulsive effort to be provided, to reach walking, to pull, draw purposes such as transportation, farm work; The little trailing wheel of its front-wheel is big, and it is less that the front axle quality accounts for the ratio of complete machine quality, and the two-wheel drive trac. of producing with design voluntarily of China's import is the type of front axle lighter weight.With respect to the performance characteristics of four-wheel drive tractor, the two-wheel drive trac. mainly shows as: do not draw preferably that adhesion value, road-holding property and manoevreability are relatively poor, phenomenon such as hillside fields job stabilization and crossing ability difference, so its field of application is smaller.
At present, the propons ground Clearance of common two-wheel drive trac. generally has only about 0.4 meter, and the general maximum of the wheelspan of two front-wheels can only reach 1.8 meters, can not satisfy the agricultural tillage needs in zones such as Xinjiang far away; Although the trac. of crack, the highland propons of horsepower two-wheel drive in having successively in recent years; Even also has crack, the highland propons trac. of high-power (as 80 horsepowers); But its crack, mono-propons ground and maximum wheelspan are less; Caused the application market scope of the type trac. narrower and small, can not satisfy the diversified requirement of some regional agricultural tillage, can not change the ground Clearance of propons and widen propons spoke distance.
Deep from many aspects market study learns that the row spacing in the arable land in many zones has variation to require: the narrower wheelspan of the needs that have is as about 1.8 meters, and 2.05 meters the wheelspan that then needs that has could satisfy arable land row spacing requirement; In addition, the time of agricultural tillage is more concentrated, often in less than the time of two weeks, just accomplished plough, the operation in early stage of agriculturals such as plough, rake, sowing; The period of service that this has shortened the type trac. greatly, it is idle to make that common trac. occurs, and causes the wasting of resources; But can not to different arable land row spacing adjust wheelspan and realize farming needs like operations such as fertilising, spray medicines the mid-term that can not carry out agricultural tillage; In the time of can't treating that also the agricultural tillage harvest is accomplished, reduce the needs that the field transportation is accomplished in the crack, ground.This monistic trac. has not met the purchase intention of peasant household.
In view of the foregoing, the preceding Biodge device of existing two-wheel drive trac. needs to improve.
The utility model content
The purpose of the utility model is in order to overcome deficiency of the prior art; A kind of preceding Biodge device of adjusting crack, trac. ground and wheelspan is provided; Can adjust the ground Clearance of propons according to different agricultural tillage needs, the spoke that also can adjust propons according to different arable land row spacings is apart from the needs that reach the adjustment wheelspan; Dismounting is easy to adjust quick, thereby realizes a tractor serves several purposes, economizes on resources greatly, obviously improves resource utilization and work efficiency, effectively increases field of application, reduces production costs greatly and invests, and is convenient to promote.
The utility model adopts following technical scheme in order to realize above-mentioned purpose: a kind of preceding Biodge device of adjusting crack, trac. ground and wheelspan is by secondary sleeve pipe, crossbeam master sleeve pipe; Intermediate rod, stub, main pin casing, steering swivel semiaxis; The steering swivel adapter plate, wheel set, bolt, reinforced rib constitutes; Two ends in the crossbeam master sleeve pipe are coaxial to be provided with secondary sleeve pipe, and an end of secondary sleeve pipe is provided with main pin casing, the coaxial stub that is provided with in the main pin casing; One side horizontally set intermediate rod of stub upper end, the stub lower end is provided with the steering swivel adapter plate; One side correspondence of steering swivel adapter plate is provided with the steering swivel semiaxis, the coaxial wheel set that is provided with of a side of steering swivel semiaxis.
Axial corresponding at least three holes of reservation that are uniformly distributed with on secondary sleeve pipe and the crossbeam master sleeve pipe are provided with bolt in the hole.
Secondary sleeve pipe and the inboard angle of main pin casing are provided with leg-of-mutton reinforced rib.
At least two holes of corresponding reservation on steering swivel semiaxis and the steering swivel adapter plate are provided with bolt in the hole.
Intermediate rod and secondary sleeve pipe and crossbeam master sleeve pipe are arranged in parallel.
The principle of work of the utility model is: the utility model is through changing secondary casing length and bolt mounting holes position, making wheelspan be able to adjustment in order to the spoke distance of adjusting propons; Through lengthening stub, main pin casing length and change slewing journal structure,, the wheelspan of two-wheel drive farm tractor front axle and the adjustment of ground Clearance have been realized in order to the ground Clearance of adjustment propons.
Main pin casing has been realized the adjustment of crack, one-level ground, rotates to lower position through the steering swivel semiaxis again and realizes the adjustment of crack, secondary ground, if when need crack, common ground coming operation, can the steering swivel semiaxis be rotated to the high position and realize.
The beneficial effect of the utility model is: simple in structure, assembly and disassembly is convenient and swift, dependable performance, safety of operation; Convenient and practical, functional diversities; Can adjust the ground Clearance of propons according to different agricultural tillage needs, the spoke that also can adjust propons according to different arable land row spacings is apart from the needs that reach the adjustment wheelspan; Dismounting is easy to adjust quick, thereby realizes a tractor serves several purposes, has practiced thrift resource greatly, has obviously improved resource utilization and work efficiency, has effectively increased field of application, and productive costs is low with investment, is convenient to promote.
The utility model not only can be ploughed, plough, harrows, sows the early stage of agricultural tillage; And the mid-term of agricultural tillage can apply fertilizer, spray operations such as medicine; The terminal driving device of dismounting reduces the crack, ground when treating agricultural tillage harvest completion, accomplishes the needs of field transportation.Because can through the ground Clearance of adjustment trac. accomplish like operations such as fertilising, spray medicines the mid-term of agricultural tillage; To different arable land row spacings, can also realize the farming needs through the adjustment wheelspan; Reduce the needs that the field transportation is accomplished in the crack, ground when treating the agricultural tillage harvest again.The work adjustment needs of trac. alley width have been realized in the difference arable land.
The utility model has obviously improved traction adhesion value, road-holding property, hillside fields job stabilization, and manoevreability and crossing ability are good, so its field of application compares broad.The utility model can be widely used in can adapting to the needs of various agricultural tillages on 65～100 horsepowers of wheel-tire tractor propons, is applicable to the domestic consumer of various small scale-farms or single type; Alleviate its economical burden greatly, fully satisfy the demand in user and market.
