The first left rake teeth 311 and the first right rake teeth 312 move towards on first reverse-flighted screw 4 or backwards to shiftings
It is dynamic；Similarly, the described second left rake teeth 321 and the second right rake teeth 322 moved towards on second reverse-flighted screw 5 or
Backwards to movement, so as to adjust the spacing between adjacent two rake teeth as needed.Due to the rotating speed of the first stepping electricity 61
It is twice of the rotating speed of second stepper motor 62, so the step number that first rake teeth 31 moves in same time is institute
State the movement of the second cake tooth 32 twice of step number, displacement stroke is also twice of the second rake teeth 32, is ensured that when any
The equal in magnitude of adjacent two spacing is carved, 5 rake teeths is equally spaced all the time, and then helps uniformly to ted article, grain
Food, make to ted better.
Second embodiment：
Fig. 4 is refer to, the difference of second embodiment and above-mentioned first embodiment is：Described interval adjustable is semi-automatic
Cereal crops tedder only has a stepper motor 7, and the stepper motor 7 is provided with driving wheel, the He of the first reverse-flighted screw 4
Second reverse-flighted screw 5 is connected with the first rotation drive structure and the second rotation drive structure respectively, and described first rotates drive
Dynamic structure and second rotation drive structure are respectively the first driven pulley 71 and the second driven pulley 72, and first driven pulley
71 and second driven pulley 72 be connected respectively by belt with the driving wheel, the radius of second driven pulley 72 is described
Twice of the radius of first driven pulley 71, when being rotated so as to the stepper motor 7, the rotating speed of first driven pulley 71 is described
Twice of the rotating speed of second driven pulley 72.The handle 1 is provided with control module 11, the control module 11 and stepping electricity
Machine 7 electrically connects.
The beneficial effect that the technical scheme that embodiment of the present utility model provides is brought is：Spacing of the present utility model is adjustable
The semi-automatic cereal crops tedder of formula, by first rotation drive structure, (i.e. the first stepper motor 61 or first is driven
71) wheel, drives first reverse-flighted screw 4 to rotate, so that 2 first rake teeths coordinated with first reverse-flighted screw 4
31 occur move toward one another or backwards to moving, and pass through second rotation drive structure (i.e. the second stepper motor 62 or second
Driven pulley 72), drive second reverse-flighted screw 5 to rotate, so that coordinate with second reverse-flighted screw 5 two described second
Rake teeth 32 occurs move toward one another or backwards to motion, and then makes 2 first rake teeth, 31 and 2 second rake teeths 32 and institute
The spacing stated between fixed rake teeth 33 changes, so as to not only can according to it is specific need come to adjacent two rake teeths it
Between spacing size be adjusted, and adjust after adjacent two spacing it is equal in magnitude so that ted uniformly, it is better.
In the case where not conflicting, the feature in embodiment and embodiment herein-above set forth can be combined with each other.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
