Abstract
The invention provides a crescent rake tooth. The crescent rack tooth comprises a tooth tip, a tooth body, a connecting portion and a tooth root, wherein the tooth body and the tooth root are respectively connected to two ends of the connecting portion; the top of the tooth body is connected with the tooth tip; the tooth tip, the tooth body and the connecting portion are subjected to plastic spraying treatment; the thickness of a plastic layer is not smaller than 120mm; the breaking force of the rake tooth is not smaller than 800 kilograms after the rake tooth is subjected to heat treatment HRC40-46; the whole rake tooth is crescent; and four equidistant grooves are formed in a surface of the tooth body along the length direction. A soil facing area of the crescent rake tooth is small; and the surface of the crescent rake tooth is subjected to plastic spraying treatment. The crescent rack tooth has the advantages that the resistance is small, sundries cannot be hung on the crescent rake tooth easily, the breakage rate is high, and the crescent rake tooth is rust-proof. Moreover, the crescent rake tooth is high in work efficiency and is durable.
Description
Technical field
The present invention relates to farm equipment application, particularly a kind of crescent rake teeth.
Background technology
Existing target odontoid is four distracted centrums, because it is a plane or curved surface slightly that native face is met in fragmentation, 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 process, so target tooth is easy to corrosion, serious even cannot use, and service life is short.Foreign material are removed and simple antirust treatment by people 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 a kind of crescent rake teeth with the high and anti-corrosion of little, the not easy to hang foreign material of resistance, percentage of damage.
Technical solution of the present invention is: a kind of crescent rake teeth, comprises crown, denticle, connecting portion and tooth root, and described denticle and tooth root are connected to connecting portion two ends, and described denticle top connects crown; Described crown, denticle and connecting portion all do plastic-blasting process, mould layer thickness and be not less than 120mm, described rake teeth passes through through Overheating Treatment, hardness is HRC40-46, rupture pull force is not less than 800 kilograms, described rake teeth entirety is in crescent shape, and the surface that described denticle is gone up along its length is provided with four equidistant grooves.
The present invention further improves and is: described denticle is circular platform type, and in arc surface between the adjacent grooves on connecting portion, described denticle, connecting portion two hold connection greatly.
The present invention further improves and is: described crown is pyramid type.
Further improvement of the present invention is: described tooth root is provided with screw thread, and is coated with oil processing through primary colors, and it is also rotary with nut.
The invention has the beneficial effects as follows: it is little that the present invention meets native area, surface is through plastic-blasting process, and have the advantages such as the high and anti-corrosion of little, the not easy to hang foreign material of resistance, percentage of damage, therefore its operating efficiency is high, durable in use.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Number in the figure is:
1, crown; 2, denticle; 3, connecting portion; 4, tooth root.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
As shown in Figure 1, crescent rake teeth provided by the invention, comprises crown 1, denticle 2, connecting portion 3 and tooth root 4, and described denticle 2 and tooth root 4 are connected to connecting portion 3 two ends, and described denticle 2 top connects crown 1; Described crown 1, denticle 2 and connecting portion 3 all do plastic-blasting process, mould layer thickness and be not less than 120mm, described rake teeth is through Overheating Treatment, hardness is HRC40-46, rupture pull force is not less than 800 kilograms, described rake teeth entirety is in crescent shape, and the surface that described denticle 2 is gone up along its length is provided with four equidistant grooves.
Described denticle 2 is in circular platform type, and in arc surface between the adjacent grooves on connecting portion 3, described denticle 2, connecting portion 3 two hold connection greatly.
Described crown 1 is in pyramid type.
Described tooth root 4 is provided with screw thread, and is coated with oil processing through primary colors, and it is also rotary with nut.
The above; be only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
