Abstract
The invention provides an RT type harrow tooth. The RT type harrow tooth comprises a tooth tip, a tooth body, a connecting portion and a tooth root, wherein the tooth body and the tooth root are connected with the two ends of the connecting portion respectively, the top of the tooth body is connected with the tooth tip, the whole tooth body is in a circular truncated cone shape, the section of the tooth body is a waist-drum-shaped section in an arc transition mode. The RT type harrow tooth is made of alloy spring steel through forging, and the section of the tooth body is in the waist-drum shape in the arc transition mode. By means of the design, the RT type harrow tooth has the advantages that materials which are used are less, the elasticity modulus is large, the direction of material fibers of the portion on which force is exerted is reasonably arranged, and therefore the weight of the product is reduced, the fatigue strength is enlarged, the service life is prolonged, and the detection and the application show that the fatigue strength is improved by 2 times to 2.5 times, and the service life is prolonged by 15 times to 20 times.
Description
Technical field
The present invention relates to farm equipment application, particularly a kind of RT type rake teeth.
Background technology
Existing target odontoid is four distracted centrums, because broken, meeting native face 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, because lacking anti-corrosion, its surface processes simultaneously, 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.
Summary of the invention
In order to overcome the defect of prior art, the invention provides that a kind of to have materials few, elastic modelling quantity is large, the RT type rake teeth of the large and long service life of fatigue strength.
Technical solution of the present invention is: a kind of RT 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 integral body is circular platform type, and its section waist-drum-shaped cross section that is arc transition.
The present invention further improves and is: described connecting portion is respectively connected with up and down cylinder by a round platform and forms.
The present invention further improves and is: described connecting portion both sides relative position also offers triangular groove.
The present invention further improves and is: described crown is pyramid type.
The present invention further improves and is: described tooth root is cylinder shape, which is provided with screw thread.
Further improvement of the present invention is: the whole alloy spring steel that adopts of described RT type rake teeth processes through forging.
The invention has the beneficial effects as follows: RT type rake teeth of the present invention adopts alloy spring steel to process through forging, Section Design is the waist-drum-shaped cross section 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.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram that the present invention executes example one.
Fig. 2 is the cross section that the present invention executes example one denticle.
Number in the figure is:
1, crown; 2, denticle; 3, connecting portion; 4, tooth root; 5, triangular groove.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
As shown in Figure 1, 2, RT type rake teeth provided by the invention, 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 integral body are circular platform type, and its section waist-drum-shaped cross section that is arc transition.
Described connecting portion 3 is respectively connected with up and down cylinder by a round platform and forms.
Described connecting portion 3 both sides relative positions also offer triangular groove 5.
Described crown 1 is pyramid type.
Described tooth root 4 is cylinder shape, which is provided with screw thread.
The whole alloy spring steel that adopts of described RT type rake teeth processes through forging.
The above; it is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
