The utility model relates to a speed transform device for rotary tillers, comprising a shift fork assembly, a gear lever assembly, a change gear group, a guiding bar, and a disengagement preventing support, which is characterized in that: the integral shift fork assembly is composed of two shift forks, a sliding sleeve, and a connecting rod for the two shift forks; a connecting member is respectively arranged on the upper part of each shift fork; the two shift forks are fixedly connected as a whole by the connecting rod through the connecting members; the shift fork assembly is sleeved on the guiding bar through the sliding sleeve; the disengagement preventing support is composed of a middle top-pillar, a left and a right connecting plate; a fixed block is arranged on the middle top-pillar. The speed transform device for rotary tillers has the advantages that: since the sliding is control by the fixed block of the disengagement preventing support, the structure is more rational and the slippage is mall; the positions of sliding gears are easy to be adjusted, so as to realize complete meshing, prevent the incomplete meshing and extend the service life; since the length of the shift forks is shortened and the shift forks are connected as a whole, the rigidity of the shift fork assembly is improved without being easily deformed.
Description
Technical field
The utility model relates to a kind of speed change gear that is applicable to rotovator.
Background technology
Rotovator speed change gear of the prior art comprises shifting fork assembly, gear lever assembly and change-speed gearing group, and described shifting fork assembly comprises shift fork and guide post.Its defective is: shift fork is to be fixed on the guide post, relies on the guide post lock screw to fix the slippage of balladeur train, drives moving forward and backward of shift fork, and the shift fork position fixedly is to rely on the lock screw on the guide post to fix during work.Because the coupling mechanism force of lock screw is less, stressed bigger, loosening easily distortion displacement, service life is short, inconvenient operation; Distortion is bigger in the shift fork use, and the slippage of balladeur train is big during work, and is incomplete with the engagement of change-speed gearing, being easy to generate dislocation engagement, and phenomenon out of supply happens occasionally; And the guide post sealing is bad, easily oil impregnate.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, provides a kind of structure the more reasonable rotovator speed change gear that also can effectively prevent phenomenon generation out of supply.
Technical problem to be solved in the utility model is to realize by following technical scheme.The utility model is a kind of rotovator speed change gear, comprises shifting fork assembly, gear lever assembly and change-speed gearing group, is characterized in, it also is provided with guide post and anti-support out of supply;
Described shifting fork assembly is monolithic construction, it comprises 2 shift forks, sliding sleeves and is connected the connecting rod of shift fork, shift fork top respectively is provided with a contiguous block, connecting rod by contiguous block with 2 fixedly connected being integral of shift fork, described sliding sleeve fixedly is located on the lock sleeve of shift fork front end, and described shifting fork assembly is set on the guide post by sliding sleeve;
Described anti-support out of supply comprises middle fore-set, and the two ends of middle fore-set are fixed with left and right connecting plates, and the front portion of left and right connecting plates is through on the guide post, the rear portion is provided with set screw and locking pin, also is provided with fixed block on the middle fore-set;
Described sliding sleeve is enclosed within on the guide post between the left and right connecting plates.
During assembling, the left and right connecting plates front portion of anti-support out of supply is through on the guide post, thereby makes anti-support out of supply do the oscilaltion campaign around guide post, and it is axially located by set screw.During gear shift, mention locking pin, the push-and-pull control stick carries out gear shift, puts down locking pin after performing.
Anti-support out of supply and shifting fork assembly are installed on the guide post simultaneously, when support anti-out of supply rises, shifting fork assembly can move forward and backward, when anti-support out of supply puts down, contact with contiguous block on the shift fork by fixed block, the slippage of control shifting fork assembly realizes the fixedly effect of balladeur train when work, prevent effect out of supply thereby reach.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of rotovator speed change gear is characterized in that described gear lever assembly comprises control stick, and the front end of control stick is provided with little shift fork, and described little shift fork is stuck on the fork slot on the connecting rod.Like this, by the push-and-pull control stick, drive the shifting fork assembly front and back and slide.Control stick just drives the shifting fork assembly slip during work, and shifting fork assembly is located by anti-support out of supply during work, and itself does not stress control stick, so the service life of having improved control stick greatly, and easy to operate.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of rotovator speed change gear is characterized in, described connecting rod is " " font structure that is connected with vertical pole by cross bar, and described cross bar is shift fork fixedly, and fork slot is located on the vertical pole.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of rotovator speed change gear is characterized in, is fixed with steering ball on control stick.During assembling, the steering ball on the control stick is put in the steering ball groove of gearbox cover plate and be fixed up.Push-and-pull control stick in front and back turns to by steering ball, and little shift fork also can move forward and backward in gearbox during use.Like this, realize ball face sealing, be difficult for oil impregnate.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of rotovator speed change gear is characterized in that lock sleeve is provided with locking hole, fixes by the lock screw that is located on the locking hole between sliding sleeve and the lock sleeve.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of rotovator speed change gear is characterized in that the rear portion of connecting plate is provided with the locking pin-and-hole, and described locking pin is connected on the locking pin-and-hole by securing member, and locking pin is provided with locking spring and lock screw.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of rotovator speed change gear is characterized in that described change-speed gearing group is 2 groups.
Compared with prior art, the utlity model has more rational structure, it controls slippage by the fixed block of anti-support out of supply, and slippage is little; The balladeur train position is adjusted easily, can realize the effect that meshes fully, prevents the not exclusively generation of the phenomenon of engagement, prolongs its service life; Can shorten the length of shift fork, and the shift fork connection is in aggregates, has improved the rigidity of shifting fork assembly, not yielding.The utility model mainly is used on the rotovator, also is applicable to the occasion that other can be suitable for.
