Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of tillage knife of mini-tiller jockey of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
With reference to Fig. 1, tillage knife of mini-tiller jockey, comprise mini-size tillage machine joint 1, connecting rod 2 and cultivated cutter joint 3, plough cutter joint 3 and be provided with cultivated cutter installing hole 4, also comprise U-shaped pin rod 5, postive stop baffle 6, spring 7, spring stop 8, postive stop baffle 6 is provided with the first pin rod hole, plough cutter joint 3 and be provided with the second pin rod hole, U-shaped pin rod 5 is slidably arranged in the first pin rod hole and the second pin rod hole, spring stop 8 is arranged on U-shaped pin rod 5, spring 7 is enclosed within U-shaped pin rod 5 and between spring stop 8 and postive stop baffle 6, U-shaped pin rod 5 is provided with pull head 9.
In the present embodiment, plough outside cutter joint 3 and be also provided with the first chute 31, described spring stop 8 is provided with the slippery fellow 81 coordinated with the first chute 31.After first chute 31 and foxy 81 are set, make that U-shaped pin rod 5 is stressed in the process of sliding more to be balanced, firmly more economize, and slip is more also more smooth and easy.
In the present embodiment, described first chute 31 is dovetail groove, and described foxy 81 is swallow-tail form head.Dovetail groove and swallow-tail form header structure are simply, easy to process, producing raw originally low, in order to reach better sliding effect, also can install pulley additional on swallow-tail form head, and such first chute 31 and slippery fellow 81 coordinate the meeting of slip more smooth and easy.
In the present embodiment, described U-shaped pin rod 5 comprise connect successively slide bar portion 51, middle interconnecting piece 52 and pin rod portion 53, slide bar portion 51 is slidably arranged in the first pin rod hole, and pin rod portion 53 is arranged in the second pin rod hole, and described pull head 9 is arranged on described middle interconnecting piece 52.Pin rod portion 53 is because will be used for fixing cultivated cutter, so the diameter in pin rod portion 53 is larger than slide bar portion 51, certain slide bar portion 51 diameter also can be the same large with pin rod portion 53 diameter, is exactly that materials can be more; Middle interconnecting piece 52 can make linear, also can do in the arc-shaped.
In the present embodiment, described middle interconnecting piece 52 is provided with the second chute 54, described pull head 9 is connected with support bar 91, support bar 91 is through the second chute 54, support bar 91 is provided with fagging 92, described pull head 9 and fagging 92 are separately positioned on the second chute 54 both sides, and described cultivated cutter joint 3 is provided with the support bar duct 93 coordinated with support bar 91.The diameter of pull head 9 and the width of fagging 92 are greater than the width of the second chute 54.
In the present embodiment, described pull head 9 is stay column or draw ring.Stay column and draw ring are common pull heads 9, and structure is simple, and cost is low, and pull head 9 also can be made other forms by certain user as required, as long as reach the object of pull.
In the present embodiment, described postive stop baffle 6 quantity is 1 or 2.Postive stop baffle quantity is 1 can save cost, if adopt two the stressed balance more of U-shaped pin rod can be made with steady.
In the present embodiment, sliding sleeve 32 is provided with in described first pin rod hole and the second pin rod hole.Arranging of sliding sleeve 32 can make the frictional force of U-shaped pin rod 5 and the first pin rod hole and the second pin rod hole less, slides more smooth and easy, also reduces the wearing and tearing of U-shaped pin rod 5 simultaneously, increases the service life of U-shaped pin rod.
When the present invention installs, as long as hold pull head 9 with finger, be pulled outwardly, just U-shaped pin rod 5 can be pulled outwardly, then along the second chute 54 1 Slideslip pull head 9, pull head 9 with support bar 91 after a Slideslip, support bar 91 withstands on cultivated cutter joint 3 outer surface, at this moment just pull head 9 can be decontroled, cutter is ploughed in the placement of vacateing two hands wholwe-hearted, after placement, slide back pull head 9 again, support bar 91 is made to aim at support bar duct 93, then decontrol, U-shaped pin rod 5 sets back under the effect of spring 7, fix cultivated cutter, simple to operate, do not need professional tool, and can not loose or dislocation in the process used, safe and reliable.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
