Abstract
The utility model provides an FT-type rake tooth. The FT-type rake tooth comprises a tooth tip, a tooth body, a connecting part and a tooth root, wherein the tooth body and the tooth root are respectively connected to two ends of the connecting part, the top end of the tooth body is connected with the tooth tip, the tooth body is integrally in a cone shape, and the cross section of the tooth body is an arc transitional four-angled star-shaped cross section. The FT-type rake tooth is formed by forging alloy spring steel, and the cross section is designed to be the four-angled star-shaped cross section transitioned in an arc form, so that fewer materials are used, the elasticity modulus is large, the fiber direction of the material on a stressed part is reasonably distributed, the weight of the product is reduced, the fatigue strength is large, the service life is prolonged, the fatigue strength can be improved by 2 to 2.5 times after being tested and used, and the service life is prolonged by 15 to 20 times.
Description
Technical field
The utility model relates to farm equipment application, particularly a kind of FT type rake teeth.
Background technology
Existing target odontoid is four rib centrums, meeting native face because broken is a plane or curved surface slightly, so its reduction resistant force is large, percentage of damage is low, very easily tangle the things such as weeds, simultaneously because its surface lacks anti-corrosion processing, so target tooth is easy to corrosion, serious even cannot use, and service life is short.People remove foreign material and simple antirust processing for a long time, more then use, and bother and waste time and energy, weak effect.Almost few people expect doing a little improvement on target tooth.The applicant, through extensively retrieval, not yet finds desirable technical solution.
Utility model content
In order to overcome the defect of prior art, it is few that the utility model provides one to have materials, and elastic modelling quantity is large, the FT type rake teeth of the large and long service life of fatigue strength.
Technical solutions of the utility model are: a kind of FT type rake teeth, comprise crown, denticle, connecting portion and tooth root, described denticle and tooth root are connected to connecting portion two ends, and described denticle top connects crown, described denticle entirety is circular platform type, and its section four jiaos of star cross sections that are arc transition.
The utility model further improves and is: described connecting portion is cylinder shape or stepped round platform.
The utility model further improves and is: described crown is pyramid type.
The utility model further improves and is: described tooth root is cylinder shape, which is provided with screw thread or connecting hole.
The utility model further improves and is: described FT type rake teeth entirety adopts alloy spring steel to process through forging.
The beneficial effects of the utility model are: the utility model FT type rake teeth adopts alloy spring steel to process through forging, Section Design is four jiaos of star cross sections of arc transition, the advantage of this design is that materials are few, and elastic modelling quantity is large, through forging processing, force part material fiber direction is arranged rationally, product weight is alleviated, and fatigue strength becomes large and extends service life, after testing and apply, fatigue strength has improved 2-2.5 doubly, has extended 15-20 service life doubly.
Brief description of the drawings
Fig. 1 is the overall structure schematic diagram that the utility model is executed example one.
Fig. 2 is the overall structure schematic diagram that the utility model is executed example two.
Fig. 3 is the cross section that the utility model is executed example one and example two denticles.Number in the figure is:
1, crown; 2, denticle; 3, connecting portion; 4, tooth root; 5, connecting hole.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.Embodiment mono-:
As shown in Figure 1,3, the FT type rake teeth that the utility model provides, comprise crown 1, denticle 2, connecting portion 3 and tooth root 4, described denticle 2 and tooth root 4 are connected to connecting portion 3 two ends, described denticle 2 tops connect crown 1, described denticle 2 entirety are circular platform type, and its section four jiaos of star cross sections that are arc transition.
Described connecting portion 3 is cylinder shape.
Described crown 1 is pyramid type.
Described tooth root 4 is cylinder shape, which is provided with connecting hole 5.
Described FT type rake teeth entirety adopts alloy spring steel to process through forging.
Embodiment bis-:
As shown in Figure 2,3, the FT type rake teeth that the utility model provides, comprise crown 1, denticle 2, connecting portion 3 and tooth root 4, described denticle 2 and tooth root 4 are connected to connecting portion 3 two ends, described denticle 2 tops connect crown 1, described denticle 2 entirety are circular platform type, and its section four jiaos of star cross sections that are arc transition.
The stepped round platform of described connecting portion 3.
Described crown 1 is pyramid type.
Described tooth root 4 is cylinder shape, which is provided with screw thread.
Described FT type rake teeth entirety adopts alloy spring steel to process through forging.
The above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
