Abstract
The invention discloses a kind of startup structure of rotovator, belong to rotovator field, solve in prior art and start structure and lack the problem that safe limiting structure has potential safety hazard.A startup structure for rotovator, comprises handrail and handle, and handle rotation is connected on handrail, and also comprise the controlling organization that can limit and shake hands to rotate relative to handrail, controlling organization is arranged on handrail.The present invention is provided with for limiting the handle starting rotary blade at arm rest, handle can be prevented to be misused and cause rotary blade accidental activation, effectively prevent some accidents.
Description
Technical field
The present invention relates to rotovator field, particularly a kind of startup structure of rotovator.
Background technology
The rake a kind of farm tools that plows is one of master operation of agro-farming, and in Modern Agricultural, the general rotovator that uses is ploughed.The actuating mechanism of rotovator is generally arranged on armrest portion, and handled easily personnel carry out the rotary blade work that rotovator controls rotovator.
In prior art, if patent publication No. is the Chinese patent of 102027817A, actuating mechanism generally comprises handrail and handle, handle rotation is connected on handrail, when operating personnel operate rotovator, while needing to hold handrail, pull handle, thus start the rotary blade of rotovator.
Above-mentioned this prior art has defect, under certain situation, operating personnel do not wish to start rotary blade, but operating personnel maloperation may pull handle and cause rotary blade to start, this just likely causes some accidents, light then damage rotary blade or motor, heavy then likely cause personnel's injury accident.
Summary of the invention
The object that the present invention will reach is to provide a kind of startup structure of rotovator, with release mechanism, can prevent rotary blade due to operating personnel's maloperation accidental activation.
In order to achieve the above object, the present invention adopts following technical scheme: a kind of startup structure of rotovator, comprises handrail and handle, and handle rotation is connected on handrail, and also comprise the controlling organization that can limit and shake hands to rotate relative to handrail, controlling organization is arranged on handrail.
Further, described controlling organization comprises position-limited rack, and position-limited rack the rotary motion trace being moveable to handle can be kept out handle shake hands to rotate relative to handrail limit relative to handrail movement.Operating personnel need, before pulling handle startup rotary blade, first position-limited rack to be moved to open position, thus can avoid surprisingly opening rotary blade and cause the accident.
Further, described position-limited rack is connected by axis of rotation with described handrail, described controlling organization also comprises the torsion spring being set in rotating shaft, and one end of torsion spring connects position-limited rack, the other end connects handle, and torsion spring produces and makes position-limited rack forward elastic force in the rotary motion trace of handle to.Torsion spring can make position-limited rack self-return, prevents from operating personnel from forgetting reversing position-limited rack causing controlling organization ineffective.
Further, described handrail is provided with chute, described position-limited rack can relatively handrail along slide to handle rotary motion trace on, described controlling organization also comprises spring, one end of spring connects position-limited rack, the other end connects handrail, and spring produces and makes position-limited rack slide into elastic force in the rotary motion trace of handle.The another kind of position-limited rack mounting structure be suitable for.
Further, described handle is provided with positive stop key, positive stop key is fixedly connected with handle or is structure as a whole, positive stop key is with handle rotation, position-limited rack can handrail movement the rotary motion trace being moveable to the positive stop key of handle keeps out positive stop key to limit positive stop key with handle rotation relatively, thus restriction handle rotates relative to handrail.Increase positive stop key and can strengthen the control effects of position-limited rack to handle.
Further, described position-limited rack comprises location division, and when position-limited rack moves in the rotary motion trace of described positive stop key, location division and positive stop key offset to limit positive stop key with handle rotation, thus restriction handle rotates relative to handrail.
Further, described position-limited rack is provided with plectrum.Operating personnel's movement limiting frame can be made more convenient.
Further, described handrail comprises handle support, and handle support is fixedly connected with handrail or is structure as a whole, and described handle is articulated with on the handle support of handrail; Described position-limited rack is connected to the handle support of handrail.Reduce the complexity of part, thus manufacture difficulty and cost can be reduced.
After adopting technique scheme, tool of the present invention has the following advantages:
Being provided with for limiting the handle starting rotary blade at arm rest, handle can being prevented to be misused and cause rotary blade accidental activation, effectively prevent some accidents.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the schematic diagram that in an embodiment of the present invention, position-limited rack is in the closed position;
Fig. 2 is the schematic side view of middle position-limited rack embodiment illustrated in fig. 1;
Fig. 3 is middle position-limited rack embodiment illustrated in fig. 1 schematic diagram in an open position;
Fig. 4 is the schematic diagram that middle handle embodiment illustrated in fig. 1 starts rotary blade.
Embodiment
Fig. 1-Figure 4 shows that a kind of embodiment of the present invention.
Handrail 1 is provided with handle support 3, and handle support 3 is welded on handrail 1, and handle 5 is hinged on handle support 3, and the rotary blade that can control rotovator starts.By rotating shaft switching limited location frame 4 on handle support 3, position-limited rack 4 rotates on handle support 3, handle 5 is provided with positive stop key 2, positive stop key 2 rotates with handle 5, position-limited rack 4 can turn on the movement locus of positive stop key 2, namely reach closed position, now the limiting section 41 of position-limited rack 4 offsets with positive stop key 2 rotation limiting positive stop key 2, thus handle 5 cannot be pulled.Be provided with the torsion spring (not shown) be socketed in rotating shaft between position-limited rack 4 and handle support 3, torsion spring produces and makes position-limited rack turn to the elastic force of closed position, prevents from operating personnel from forgetting reversing position-limited rack causing controlling organization ineffective.Position-limited rack 4 is also provided with plectrum 6, makes operating personnel can stir plectrum 6 easily with movement limiting frame 4.
When operating personnel need to start the rotary blade of rotovator, need first position-limited rack 4 to be moved to open position, then just can pull handle 5 and start rotary blade, handle so just can be prevented to be misused and cause rotary blade accidental activation, effectively prevent some accidents.
In addition, with above-described embodiment unlike, also a chute can be set on handle support, in chute, arrange spring, and be slidably connected in the chute of handle support by position-limited rack, position-limited rack is slidably on the movement locus of positive stop key, i.e. closed position, keep out positive stop key to rotate to limit positive stop key, thus handle cannot be rotated, spring produces and makes positive stop key slide to the elastic force of closed position.
Except above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make various change and distortion according to the present invention, only otherwise depart from spirit of the present invention, all should belong to the scope that claims of the present invention define.
