Description
Technical field
The utility model relates to a kind of chain, particularly relates to a kind of cropper feeding chain.
Background technology
In recent years, world's agricultural machinery industry develops rapidly, and our country is also in the development of vigorously supporting agricultural machinery industry, and this just needs a large amount of high-quality agricultural machinery chain. For the feeding chain of large-scale cropper, be mainly that grain, stalk etc. are transported in thresing machine, stressed large, the work under bad environment of chain, this just requires chain to have high strength and high-wearing feature. Meanwhile, because feeding chain and chain harrow collocation are used, require chain to want flexible operation on the one hand, require on the other hand attached plate and bearing pin cooperation place will have high-wearing feature.
The feeding chain that the technical problems to be solved in the utility model is to provide a kind of high strength, high-wearing feature and goes slick.
Application number is that 201210536417.0 Chinese patent discloses a kind of high abrasion carrier chain, carries out impewdance matching by the interior outer plate both sides after conventional heat treatment, has improved carrier bar both sides hardness, has increased chain wearability. This method has increased by a step heat treatment, and efficiency is low, and cost is high.
Application number is that 201220018354.5 Chinese patent discloses a kind of wear-resisting chain, by improve the wearability of chain at bearing pin plating hard chromium on surface. Bearing pin chromium plating can improve the wearability of chain, but can not solve the more serious problem of bearing pin wearing and tearing that feeding chain coordinates with attached plate.
Summary of the invention
The technical problems to be solved in the utility model is to overcome existing defect, feeding chain for the cropper that provide a kind of high abrasion, high strength, goes slick.
Technical solutions of the utility model are:
A kind of agricultural harvester feeding chain, comprise inner plate, outer plate, attached plate, the first bearing pin, the second bearing pin, sleeve, roller, described inner plate coordinates with sleeve for interior single-unit, described the first bearing pin coordinates with outer plate for outer single-unit, described the second bearing pin coordinates with attached plate for attached plate single-unit, described the first bearing pin and the second bearing pin are connected in series chain through sleeve, the length of described the second bearing pin is greater than the length of the first bearing pin, described attached plate and outer plate are arranged by rule, and chain attached plate thickness is greater than the thickness of inner plate and outer plate.
Feeding chain is used in combination by attached plate and chain harrow, and compared with interior outer plate, attached plate is except being subject to chain drive pulling force, the twisting resistance that brought by chain harrow, and stressed complexity when therefore attached plate place bearing pin is worked, weares and teares even more serious. Compared with prior art, the interior outer plate of attached plate described in the utility model is thicker, makes attached plate and lengthens the increase of bearing pin faying face, has alleviated attached plate hole pressure, thereby has improved the wearability of chain.
Preferably: the large 1mm of thickness of chain attached plate Thickness Ratio inner plate and outer plate.
Preferably: the large 5mm of thickness of chain attached plate Thickness Ratio inner plate and outer plate.
Preferably: the large 2mm of thickness of chain attached plate Thickness Ratio inner plate and outer plate.
Preferably: described attached plate be L shaped, L shaped one side with the chain plate hole identical with outer plate, another side, with the bolt hole being connected with chain harrow, is connected with chain harrow by bolt.
Interfere for preventing that bolt head and attached plate from producing, preferably: between two chain plate holes, be pressed with the groove that holds bolt head.
Preferably: the first bearing pin and the second bearing pin material are steel alloy, through thermo-chemical treatment, surface grinding rear surface hard chrome plating, chromium coating thickness 0.050mm-0.085mm. The utility model chain the first bearing pin and the second bearing pin, through thermo-chemical treatment and chrome-faced, have higher wearability.
Preferably: the first bearing pin, the second bearing pin and sleeve gap are 0.5-0.6mm.
Preferably: the first bearing pin and the second pin roll end face die.
Preferably: the total sideshake 1.8-2.1mm of chain.
Preferably: described sleeve is seamless steel tube, and material is mild steel, through thermo-chemical treatment.
The chain that adopts above technical scheme to do, has good wearability and operational flexibility.
