Abstract
The invention provides an FT type rake tooth, which comprises a tooth top, a tooth body, a connecting part and a tooth root, wherein the tooth body and the tooth root are respectively connected with the two ends of the connecting part, the top end of the tooth body is connected with the tooth top, the whole body of the tooth body is in a circular truncated cone shape, and in addition, the cross section of the tooth body is a four-pointed-star-shaped cross section in circular arc transition. The FT type rake tooth is made of alloy spring steel through forging processing, the cross section is designed into the four-pointed-star-shaped cross section in the circular arc transition, and through the design, the FT type rake tooth has the advantages that the material consumption is low, the elasticity modulus is great, the forging processing is carried out, and the fiber direction distribution of the material fiber in the stress part is reasonable, so the weight of the product is reduced, the fatigue strength is increased, the service life is prolonged, through the detection and the application, the fatigue intensity is improved by 2 to 2.5 times, and the service life is prolonged by 15 to 20 times.
Description
Technical field
The present invention relates to farm equipment application, particularly a kind of FT type rake teeth.
Background technology
Existing target odontoid is four rib 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 FT type rake teeth of the large and long service life of fatigue strength.
Technical solution of the present invention is: 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 integral body is circular platform type, and its section four jiaos of star cross sections that are arc transition.
The present invention further improves and is: described connecting portion is cylinder shape or stepped round platform.
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 or connecting hole.
Further improvement of the present invention is: the whole alloy spring steel that adopts of described FT type rake teeth processes through forging.
The invention has the beneficial effects as follows: FT type rake teeth of the present invention 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.
