Abstract
The invention discloses a rotary cultivator. A fan (3) which sleeves a cutter shaft (1) and rotates with the cutter shaft (1) is used for automatically measuring revolving speed of the cutter shaft (1). Along with rotation of the fan (3), generated wind power pushes the fan (3) to move and compress a return spring (2), and when the revolving speed reaches a rated value, the fan (3) moves to a limiting position to touch a switch so as to unlock a lifting device. After the cutter shaft (1) gradually stops running, the fan (3) returns to the original position under the effect of the return spring (2) and does not touch the switch (4) again, so that the lifting device returns to be in a locking state. Therefore, the circumstance that after being inserted into soil, a blade is combined with a power output shaft, and then is bent or broken to cause unnecessary loss can be avoided effectively.

Summary of the invention
In order to overcome above-mentioned defect and deficiency the invention provides following technical scheme: rotovator, comprise cutter shaft, described cutter shaft is provided with the guide pad protruding cutter shaft outer surface, the parallel cutter shaft axis direction of described guide pad bearing of trend, one fan is set in outside described cutter shaft, described fan comprises a retainer ring, described retainer ring outer surface is fixed with flabellum, described retainer ring center is provided with the circular hole run through, the diameter described Circularhole diameter and described cutter shaft being arranged the shaft part of described fan matches, described retainer ring also has the gathering sill in the direction that parallels to the axis, described gathering sill and described guide pad match, described fan not only with described cutter shaft synchronous rotary but also can have been slided along described guide pad, one end face of described retainer ring is provided with push rod, described cutter shaft is also provided with switch and spring, the telescopic direction of described spring is identical with the axis direction of described cutter shaft, and its one end withstands on described retainer ring is provided with on the end face of push rod
When operation starts, the lifting structure of rotovator is locked, after operator's power take-off combines, cutter shaft starts to rotate, simultaneously due to interaction fan and the cutter shaft synchronous rotary of guide pad and gathering sill, along with the rotating speed of cutter shaft is more and more faster, it is faster that fan also turns, its wind-force produced is also increasing, effect fan due to wind-force starts to slide along guide pad, Compress Spring simultaneously, when the rotating speed of cutter shaft reaches rated speed, the wind-force of fan reaches maximum, spring is compressed to the limit, push rod touch switch on fan makes elevating mechanism unlock, operator just can operate rotovator and decline, blade is buried gradually to desired depth, start normal operation.After fulfiling assignment, operator disconnects power take-off, and blade axis rotary speed reduces gradually, and the wind-force of fan also reduces thereupon, and because the effect fan of spring-return power is along sliding with aforementioned rightabout, push rod is not at contact-making switch, and elevating mechanism is from newly locked.
As preferably, the cross sectional shape of described guide pad and gathering sill is rectangle.Arrange like this and can play good transmitting torque and the effect of straight-line guidance on the one hand, process also very convenient simultaneously.
Compared with prior art, the present invention has following beneficial effect: the present invention measures the rotating speed of cutter shaft automatically by being set in the fan that cutter shaft rotates together.Along with the rotation of fan, the Wind power propelling fan of generation moves and compression reseting spring, and when rotating speed reaches rated value, fan moves to extreme position touch switch and unlocks elevator.After cutter shaft gradually stall, fan is homing under the effect of back-moving spring, no longer touch switch, thus makes elevator reply lockup state.So just effectively to avoid after blade buries again in conjunction with power take-off, cause blade to bend or the unnecessary loss such as to fracture.
