Three, summary of the invention
Purpose of design of the present utility model, a kind of with regard to providing specially at the special use of the pulverizing size reduction machinery of chipping of chipping of the branch with toughness bark.In recent decades, mushroom industry development both at home and abroad is very rapid, China's edible mushroom total output in 2002 reaches 8,760,000 tons, and the output value 40,800,000,000 accounts for more than 60% of world's edible mushroom total output, earned foreign exchange in 2002 more than 500,000,000 dollar, account for 40% (China's mushroom industry status and prospects [J], guangdong agricultural science, 2005 of global edible mushroom general trade amount, 3:85～87), be the country that whole world edible mushroom is with fastest developing speed, output is maximum.Mushroom industry is the new industry that agricultural and industry, production and consumption, city and rural area, human health care and environmental protection are combined closely; progressively develop into the important component part of China's modern agriculture; same plant husbandry, aquaculture are run neck and neck; the three big pillar industries that become agricultural (are utilized ramulus mori bits development mushroom industry [J]; Jiangsu silkworm industry; 2002,24[03]: 25～26).China is that forest reserves are rare relatively; the country that timber lacks very much; be subjected to the influence of national forest conservation policy in addition; the raw material (wood chip) that is used for culture medium of edible fungus production can only adopt the branch fork; shrub; the branch bar is pulverized the back and is obtained, and therefore in vast plains region, mulberry branch is that culture medium of edible fungus is produced rare quality raw materials source.
The skin toughness of mulberry branch is very strong, cortex and wooden relative pine, the bark and wooden separately easy when chipping of cohering.Because when the cutting mulberry branch, fly cutter on the disk and charging aperture bed plate form shear action, when shearing is chipped, the bark of ramulus mori on the fly cutter one side is under the effect of fly cutting power, Ramulus Mori is cut off with the wooden of mulberry branch, and this is because the wooden part of ramulus mori plays the effect of liner Ramulus Mori; When fly cutter will cut off mulberry branch, when promptly being cut near bed plate, because there are gap (gap is generally more than 1mm) inevitably in the fly cutter on the disk and the bed plate at charging aperture place, and the thickness of Ramulus Mori is between 0.5mm～1mm, like this, just be difficult to be cut off owing to lacking to support near the Ramulus Mori on the bed plate face.Will produce a large amount of long section paper mulberry bark at the pulverizer running hours, part in these not cut paper mulberry bark may directly have been brought into pulverizing chamber, a part may be wrapped on the main shaft along the gap between fly cutter and the disk under the effect of the annular airflow that fan leaf produces in addition.When twining beginning, at first on the close axle journal at disk place, because the coefficient of friction between Ramulus Mori and the Ramulus Mori is bigger, every staggered being intertwined of bark, just be difficult to together throw away in case be staggered in, pulverizer is long more running time, will twine more and more, above-mentioned " wrapping phenomena " promptly occur.Purpose of design of the present utility model just provides a kind of special-purpose pulverizer of pulverizing at ramulus mori specially.
