Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of gear shifting structure of grain lifter gearbox, packet
The transmission short axle 1 being mounted on inside gear box and transmission gear 2 are included, 2 sets of transmission gear in transmission short axle 1, are driven short
Through-hole is radially offered on axis 1, elastic compression part 3 is placed with inside through-hole, and the end of elastic compression part 3 is equipped with locking ball
4,2 inner ring of transmission gear is equipped with shift locating groove 21, and transmission gear 2 is driven short axle 1 in the drive lower edge of shifting operating device
Shift positioning is realized in the cooperation for axially moving and passing through locking ball 4 and locating groove 21 of shifting gears, when carrying out gear shift operation,
Shifting operating device is pulled, shifting operating device directly drives transmission gear 2 to move axially in transmission short axle 1, works as positioning
When card slot 21 reaches the position of elastic compression part 3, locking ball 4 is pressed into 21 inside of locating groove to real by elastic compression part 3
Now shift positioning, the application directly drive transmission gear 2 mobile, reduce the setting of transmission mechanism by shifting operating device,
Reduce number of parts, greatly reduce processing cost and easy to maintenance, is not susceptible to when shift that clamping stagnation, shift be unsmooth or even card
Dead phenomenon improves the reliability of shift.
Preferably, elastic compression part 3 is compressed spring, and the both ends of compressed spring are respectively equipped with a locking ball 4, are changing
When gear, the locking ball 4 at compressed spring both ends is pressed into simultaneously in locating groove 21 and realizes shift positioning, improve positioning can
By property, the inaccurate phenomenon of gear engagement occurs when reducing slide piece and shift.
Further, 2 inner ring of transmission gear is equipped with 3 locating grooves 21 in the present embodiment, and 21 quantity of locating groove is
The gear number of gearbox, the gearbox of 6 gear in this way, then need 6 locating grooves 21 of required design.
Further, shifting operating device includes gear shift operating rod 5, gear lever soldering 6 and gear arm soldering 7, shift behaviour
Vertical pole 5 is connect by the first resilient key with one end of gear lever soldering 6, and the other end of gear lever soldering 6 passes through the second resilient key
It is connect with one end of gear arm soldering 7, the other end of gear arm soldering 7 is inserted between two gear rings of transmission gear 2, in this reality
It applies in example, gear arm soldering 7 directly drives transmission gear 2 to move, and shift is quick and easy, reduces the setting of transmission mechanism, subtracts
Number of parts is lacked.
Working principle: when shift, gear shift operating rod 5 is pulled, gear shift operating rod 5 finally drives gear lever soldering 6 to move, changes
Bar soldering 6 drives transmission gear 2 to axially move in transmission short axle 1, when locating groove 21 is moved to elastic compression part 3
When position, elastic compression part 3 discharges elastic force, and the locking ball 4 at both ends is pressed into locating groove 21, realizes shift positioning；Again
When secondary shift, gear shift operating rod 5 is pulled, transmission gear 2 is mobile, and locking ball 4 is pressed into transmission short axle by the inner wall of transmission gear 2
In 1 through-hole, locking ball 4 compresses elastic compression part 3, when another locating groove 21 reaches 3 position of elastic compression part,
Locking ball 4 is popped up again and is pressed into locating groove 21 by elastic compression part 3.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
