Rubber Wen Defend formula rubs threshing jaw arrangementtechnical field:
the utility model relates to a kind of rubber Wen Defend formula and rubs threshing jaw arrangement.
background technology:
current worldwide rasp bar formula rubs threshing pawl, be spheroidal graphite cast-iron or abrasion resistant cast steel is made, when the corn little to the just moisture height of results, hardness or corn seed carry out threshing, due to the rubbing effect of steel threshing pawl to corncob, to result in corn kernel impaired, broken, over the past thousands of years, because Green maize cannot threshing, be all wait for that corn carries out threshing after drying again
the problem of premier's Li Keqiang with repeatedly indicating solution grain of lying prone for this reason, country also provides various support to corn producing regions such as Heilungkiang, researchs and solves Green maize threshing problem.
utility model content:
the purpose of this utility model is to provide a kind of rubber Wen Defend formula and rubs threshing jaw arrangement.
above-mentioned object is realized by following technical scheme:
a kind of rubber Wen Defend formula rubs threshing jaw arrangement, its composition comprises: rubber rubs threshing pawl, it is steel skeleton that described rubber is rubbed in the middle of threshing pawl, outside described steel skeleton, cover has rubber to rub threshing cover, the root that described steel skeleton and rubber rub threshing cover has coaxial fixed installation hole, and the active section that described steel skeleton and rubber rub threshing cover has and takes chamber in.
described rubber Wen Defend formula rubs threshing jaw arrangement, and described fixed installation hole is shoulder hole, and steel skeleton described on central cross-section and rubber rub the root of threshing cover and active section curves 30-60 degree angle.
described rubber Wen Defend formula rubs threshing jaw arrangement, connects into steelframe between described steel skeleton, described steelframe is equipped with one group of rubber and rubs threshing cover.
beneficial effect:
1. the utility model provides a kind of rubber rasp bar formula to rub threshing pawl, is applicable to the threshing operations of corn under various state.Rubber rasp bar formula is rubbed threshing pawl and be it is characterized in that being formed by mould compacting by the soft attrition resistant materials of shape rubber-like.For improving intensity, increasing service life, interior Baogang skeleton.
when rubber rasp bar formula rub between threshing pawl and corncob, corncob and cylinder, between notch board rub threshing time; Rubber rasp bar formula rubs the Contact generation elastic deformation of threshing pawl and corncob, corn impaired little, loss less, consume energy low, efficiency is high, corn quality is good, and the corn dregs of rice are complete, are beneficial to recycling.
through autumn harvest Green maize threshing in 2014 inspection, will to receive the Green maize of returning from ground grain, timely threshing on the same day, iblet also can keep complete, and comprising plumule does not have breakage yet, solves in the world unsolved Green maize threshing problem always.
