Abstract
The invention relates to a loop chain and a chain wheel for a loop chain pull type livestock excrement channel excrement-cleaning device. The loop chain is a power transmission loop chain; the geometrical shape, chain loop width and arc radius of the loop chain correspond to those of a short loop chain for craning; and a pitch diameter ratio and all the mechanical properties are more suitable for power transmission. The chain wheel is the chain wheel for the power transmission loop chain; the shape and size of the chain wheel correspond to those of a craning loop chain driving chain wheel; chain nests and chain teeth are provided with meshed arcs, so that the problems of chain shearing, chain biting, chain hanging, teeth collapsing, and the like, are avoided; the length of the chain nests is more than 7.6%-10% of the length of the chain loop and the chain is allowed to extend properly; and the pitch diameter ratio of the chain loop is more than 3.1 but less than 3.6, so that the chain wheel is thick in chain teeth, high in strength, durable and free from relay replacement.
Description
Technical field
The present invention relates to the chain and the sprocket wheel of livestock and poultry coprodaecum excrement cleaning device, especially the loop chain of the towed excrement cleaning device of loop chain and sprocket wheel.
Background technique
Existing towed scraper plate excrement cleaning device generally adopts the lifting loop chain, and the traction scraper plate is collected ight soil.Its driving sprocket wheel has rectangle sprocket and rectangle chain nest, and is as depicted in figs. 1 and 2.
The pitch diameters of lifting loop chain is smaller, so the sprocket of sprocket wheel is thin, and intensity is low, and is fragile.
The specific elongation of lifting loop chain is bigger, and therefore the chain link of the chain nest prolongation hard to tolerate of sprocket wheel causes floating chain, jumping chain, sprocket wheel relay to change.
The rectangle sprocket is cut chain, is stung chain, chaining, collapses problems such as tooth, is conspicuous, and practical problem is also given prominence to.
Summary of the invention
Technical problem to be solved by this invention is: a kind of power transmission loop chain is provided, and the pitch diameters that solves the lifting loop chain is than the little and big problem of specific elongation; A kind of power loop chain driving sprocket wheel is provided, solves lifting loop chain driving sprocket wheel problem.
The technical solution of said technical problem is:
A kind of power transmission loop chain, geometrical shape, chain ring width and radius of arc, corresponding rising reused pitch chain; Its pitch diameters ratio is greater than 3.1, less than 3.6.
Said power transmission loop chain, diameter equals 12-13mm, and pitch equals 37-47mn.
Said power transmission loop chain, diameter equals 13.1-14mm, and pitch equals 41-50mm.
Said power transmission loop chain, diameter equals 14.1-15mm, and pitch equals 44-54mm.
Said power transmission loop chain, minimum Breaking stress is greater than 600N/m m
2
Said power transmission loop chain, proof stress is greater than 500N/m m
2
Said power transmission loop chain, the maximum elongation rate is less than 1.4% under the test load.
Said power transmission loop chain, the minimum elongation rate is greater than 12% when disrumpent feelings.
A kind of power loop chain driving sprocket wheel, shape and size, corresponding lifting loop chain driving sprocket wheel; Chain nest and sprocket have the engagement circular arc; Chain nest length is greater than chain ring length 7.6%-10%; Chain link pitch diameters ratio is greater than 3.1, less than 3.6.
Structural feature of the present invention and beneficial effect are: the pitch diameters of power loop chain is bigger, and mechanical property is higher, is fit to power transmission.Because the pitch diameters of power loop chain is bigger, so the chain transverse tooth thickness of driving sprocket wheel, intensity is high, and is wear-resistant, need not relay replacement sprocket wheel.Chain nest and sprocket with engagement circular arc are not cut chain, are stung chain, chaining, collapse problem such as tooth.Chain nest length can allow that greater than chain ring length 7.6%-10% chain extends in right amount.
Description of drawings
Further specify the present invention below in conjunction with accompanying drawing.
Fig. 1 does not mesh the lifting loop chain driving sprocket wheel of circular arc, axonometric drawing
Fig. 2 has the lifting loop chain driving sprocket wheel that meshes circular arc, axonometric drawing
Fig. 3 has the power loop chain driving sprocket wheel that meshes circular arc, axonometric drawing
Mark among the figure: 1-sprocket; 2-chain nest; 3-meshes circular arc
Embodiment
The embodiment who is described with reference to the drawings below is exemplary; Only explain the present invention, can not limit the present invention.
Example 1. power transmission loop chains, geometrical shape, chain ring width and radius of arc, corresponding rising reused pitch chain; Its pitch diameters ratio is greater than 3.1, less than 3.6.Said diameter equals 13.1-14mm, and pitch equals 41-50mm.
Said power transmission loop chain, minimum Breaking stress is greater than 600N/m m
2, proof stress is greater than 500N/m m
2, the maximum elongation rate is less than 1.4% under the test load, and the minimum elongation rate is greater than 12% when disrumpent feelings.
Example 2. power loop chain driving sprocket wheels, as shown in Figure 3.Its shape and size, corresponding lifting loop chain driving sprocket wheel; Chain nest 2 has engagement circular arc 3 with sprocket 1; Chain nest 2 length are greater than chain ring length 7.6%-10%; Chain link pitch diameters ratio is greater than 3.1, less than 3.6.
Protection scope of the present invention is defined by claims, is not limited to above several practical implementation example.The those of ordinary skill of technical field need not to break away from technical conceive of the present invention and protection domain under the present invention, can obtain various increases, replacement and change.
