Abstract
The invention discloses a starting structure of a rotary cultivator, and belongs to the field of rotary cultivators. The problem that a starting structure in the prior art lacks of a safety limiting structure and has potential risk is solved. The starting structure of the rotary cultivator comprises an armrest, a pull handle and a control mechanism, the pull handle is connected to the armrest rotationally, and the control mechanism which is arranged on the armrest is capable of limiting the pull handle to rotate relative to the armrest. The pull handle used for limiting and starting a rotary blade is arranged on the armrest, the pull handle can be prevented from misoperation to cause accidental starting of the rotary blade, and some accidents are avoided effectively.
Description
Technical field
The present invention relates to the startup structure in rotovator field, particularly a kind of rotovator.
Background technology
The rake a kind of farm tools that plows is one of master operation of agro-farming, and the general rotovator that uses is ploughed in the contemporary agricultural.The actuating mechanism operated by rotary motion of rotovator is in armrest portion, while the handled easily personnel carry out the rotary blade work that rotovator is controlled rotovator.
In the prior art, be the Chinese patent of 102027817A as patent publication No., actuating mechanism generally comprises handrail and handle, handle rotation is connected on the handrail, when operating personnel operate rotovator, pull handle when need hold handrail, thereby start the rotary blade of rotovator.
Above-mentioned this prior art has defective, under the certain situation, operating personnel do not wish to start rotary blade, but operating personnel may maloperation pull handle causes rotary blade to start, this just might cause some accidents, gently then damage rotary blade or motor, heavy then might cause personnel's injury accident.
Summary of the invention
The purpose that the present invention will reach provides a kind of startup structure of rotovator, has release mechanism, can prevent rotary blade owing to operating personnel's maloperation and accidental activation.
In order to achieve the above object, the present invention adopts following technical scheme: a kind of startup structure of rotovator, comprise handrail and handle, and handle rotation is connected on the handrail, but also comprises the controlling organization that limit handle is rotated relative to handrail, and controlling organization is arranged on the handrail.
Further, described controlling organization comprises position-limited rack, and position-limited rack can and be moveable to relative to handrail movement keeps out handle on the rotary motion trace of handle and rotate relative to handrail with limit handle.Operating personnel need at first move to open position with position-limited rack pulling before handle starts rotary blade, thereby can avoid accident to open rotary blade causing the accident.
Further, described position-limited rack and described handrail are rotationally connected by rotating shaft, described controlling organization also comprises the torsion spring that is set in rotating shaft, and an end of torsion spring connects position-limited rack, the other end connects handle, and torsion spring produces the elastic force on the rotary motion trace that makes position-limited rack forward handle to.Torsion spring can make the position-limited rack self-return, prevents that operating personnel from forgetting that dialling back position-limited rack causes controlling organization ineffective.
Further, described handrail is provided with chute, described position-limited rack handrail relatively slides on the rotary motion trace of handle along chute, described controlling organization also comprises spring, one end of spring connects position-limited rack, the other end connects handrail, and spring produces the elastic force on the rotary motion trace that makes position-limited rack slide into handle.The another kind of position-limited rack mounting structure that is suitable for.
Further, described handle is provided with positive stop key, positive stop key is fixedlyed connected with handle or is structure as a whole, positive stop key is with handle rotation, position-limited rack relatively handrail movement and being moveable to keep out on the rotary motion trace of positive stop key of handle positive stop key with the restriction positive stop key with handle rotation, thereby limit handle is rotated relative to handrail.Increase positive stop key and can strengthen position-limited rack to the control effect of handle.
Further, described position-limited rack comprises the location division, and when position-limited rack moved on the rotary motion trace of described positive stop key, location division and positive stop key offseted to limit positive stop key with handle rotation, thereby limit handle is rotated relative to handrail.
Further, described position-limited rack is provided with plectrum.It is more convenient to make operating personnel move position-limited rack.
Further, described handrail comprises the handle support, and the handle support is fixedlyed connected with handrail or is structure as a whole, and described handle is articulated on the handle support of handrail; Described position-limited rack is connected in the handle support of handrail.Reduce the complexity of part, thereby can reduce manufacture difficulty and cost.
After adopting technique scheme, the present invention has following advantage:
Be provided with the handle that starts rotary blade for restriction at arm rest, can prevent that handle from being caused the rotary blade accidental activation by maloperation, effectively avoided some accidents.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is position-limited rack schematic diagram in the closed position in an embodiment of the present invention;
Fig. 2 is the schematic side view of middle position-limited rack embodiment illustrated in fig. 1;
The schematic diagram that Fig. 3 is shown in an open position for position-limited rack in embodiment illustrated in fig. 1;
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.
When operating personnel need start the rotary blade of rotovator, need at first position-limited rack 4 to be moved to open position, just can pull handle 5 then and start rotary blade, so just can prevent that handle from being caused the rotary blade accidental activation by maloperation, effectively avoided some accidents.
In addition, different with above-described embodiment is, also can a chute be set at the handle support, spring is set in chute, and position-limited rack is slidingly connected in the chute of handle support, position-limited rack is slidably to the movement locus of positive stop key, it is the closed position, keep out positive stop key and rotate with the restriction positive stop key, thereby handle can't 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 changes and distortion according to the present invention, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
