A kind of butterfly agricultural machinery gathers in chain

Technical field

This utility model is related to transmission field, and more particularly, to a kind of butterfly agricultural machinery gathers in chain.

Background technology

Agricultural modernization is said always as giving priority to object by country for many years, but because crops and arable land various Change it is more difficult to how with unified machinery realization, in agricultural machinery work, part work can be carried out using agricultural machinery chain, to receive crops Impact less because the agricultural product price of country is not high at present, the economic level of peasant is low, the modernization machinery being used Overriding concern is cost and service life, and the machinery being used for gathering in crops on harvester needs to use a kind of agricultural machinery harvesting Chain, not only needs to prevent back-flexing, and it also requires adding adnexa, it is therefore necessary to designing a kind of low cost, is hardly damaged, Not only can effectively prevent back-flexing, and can rationally add the agricultural machinery harvesting chain of adnexa.

Utility model content

In view of the above, this utility model is exactly directed to above technical problem, there is provided a kind of butterfly agricultural machinery gathers in chain.

A kind of butterfly agricultural machinery gathers in chain, includes inner plate, outer plate, bearing pin, sleeve, roller, composition the first chain link, second Chain link, until N chain link, merges into a butterfly carrier bar, described butterfly chain positioned at two described outer plates of same chain link Plate includes longitudinally disposed two dish wing plate and a connecting plate being obliquely installed, described dish wing plate is disposed with the apex of the wing, Pin shaft hole one, delthyrium, pin shaft hole two, screens groove, the described apex of the wing is located at sustained height, the described apex of the wing and institute with described screens groove State the length that the distance between screens groove is equal to shot of a cable section, described connecting plate is provided with a square hole and a face opening Open pore.

A kind of butterfly agricultural machinery harvesting chain that this utility model provides can be further arranged to described pin shaft hole one and pin shaft hole It is provided with projection, described raised height and described bearing pin maintain an equal level between two.

When a kind of butterfly agricultural machinery harvesting chain that this utility model provides can be further arranged to be in straight configuration, positioned at the The apex of the wing of one chain link can mutually be agreed with the screens groove positioned at the second chain link.

The length that a kind of butterfly agricultural machinery harvesting chain that this utility model provides can be further arranged to shot of a cable section is 70mm- 100mm, width is 30mm-50mm, highly for 60mm-80.

A kind of butterfly agricultural machinery harvesting chain that this utility model provides can be further arranged to described connecting plate and described dish wing Plate is vertical, and horizontal by 67.5 °.

Of the present utility model preferential and have the beneficial effect that：Described butterfly carrier bar expands into butterfly-like, by punch forming, so After bend, generation process is simple, and cost is relatively low, and delthyrium both can mitigate this utility model quality, reduce loss, and can save When material is in straight configuration, the apex of the wing positioned at the first chain link can mutually be agreed with the screens groove positioned at the second chain link, effectively Prevent back-flexing.One square hole 8 and the open pore of a face opening are provided with described connecting plate, attached for adding Part, simple and practical.Described raised height and described bearing pin maintain an equal level, and are punch forming, and operation is simple, being capable of effective protection Bearing pin, effectively prevent bearing pin and receives impact it may occur that chain disconnects, or cannot bend, often take off the phenomenons such as chain. The connecting plate being obliquely installed is prevented from being hooked into the rhizome of crops.

Brief description

Below in conjunction with the accompanying drawings preferred implementation of the present utility model is just preferably described, wherein,

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the structural representation of this utility model butterfly carrier bar.

Specific embodiment

Reference picture 1- Fig. 2 is described further to a kind of this utility model butterfly agricultural machinery harvesting chain embodiment.

A kind of butterfly agricultural machinery gathers in chain, includes inner plate, outer plate, bearing pin, sleeve, roller, composition the first chain link 1, the Two chain links 2, until N chain link, finally join end to end, and drive its rotation with sprocket wheel, complete to gather in work.

Merge into a butterfly carrier bar 3 positioned at two described outer plates of same chain link, described butterfly carrier bar 3 includes longitudinal direction Two dish wing plates 4 of setting and a connecting plate being obliquely installed 5, described butterfly carrier bar 3 expands into butterfly-like, by striking out Type, then bends, and generation process is simple, and cost is relatively low.

The apex of the wing 6, pin shaft hole one, delthyrium, pin shaft hole two, screens groove 7, delthyrium are disposed with described dish wing plate 4 Both this utility model quality, reduce loss, and energy material-saving can have been mitigated.

The described apex of the wing 6 and described screens groove 7 are located at sustained height, the distance between described apex of the wing 6 and described screens groove 7 etc. In the length of shot of a cable section, when being in straight configuration, positioned at the apex of the wing 6 and the screens groove 7 positioned at the second chain link 2 of the first chain link 1 Can mutually agree with, effectively prevent back-flexing.
