Abstract
The utility model relates to a crude grinding device for straw, which is characterized in that the crude grinding device for straw is provided with a material storage cylinder with a feeding device; the middle part of the material storage cylinder is vertically provided with a rotating shaft; the rotating shaft is provided with a rotary drum; a shifting rod is fixed on the rotary drum; the lower surface of the material storage cylinder is provided with a discharge opening; a grinding chamber is arranged in the position just aligning the discharge opening; a rotary frame driven by a motor is arranged in the grinding chamber; the rotary frame is provided with a plurality of hammer sheets; the circumference and the bottom of the rotary frame are provided with screen meshes; a discharge scraper conveying device is arranged below the grinding chamber. Wheatgrass or the straw entering the material storage cylinder through a feeding belt conveyer is beaten into powder by the rotation of the rotary drum, and then is sent to the discharge opening under the action of the shifting rod; in the grinding chamber, the grass material is pulverized by rotating the hammer sheets and the pulverized grass which accords with the specification falls on the discharge scraper conveying device from holes of the screen meshes to be carried away and enters the next procedure. The utility model has the advantages of simple and reliable structure and continuous and uninterrupted work.
Description
Technical field
The utility model relates to a kind of stalk plate production equipment, particularly a kind of coarse crushing device that is used for wheat straw or straw processing.
Background technology
The forest coverage of China is about 16%, the whole nation can have only 14-15 hundred million m3 for felling the timber forest resource of utilizing at present, 2002 can be 8235m3 for industrial timber resources, and at present average annual timber total burn-off 2.5 hundred million m3 of China, wherein the industrial cut stock consumption figure is about 1.3 hundred million m3, timber year the breach amount very big.For needs that keep ecotope and lasting growth and the development of safeguarding the forest resources, must felling within quotas at a considerable time inner control timber.How to face timber resources shortage, environmental protection pressure etc. and become hot issue.
China is a large agricultural country, a large amount of grain and the economic crops of annual plantation.When gathering in the crops and processing these crops, can produce many harvesting residues (as straw, wheat straw, cotton stalk etc.) and industrial wood waste (as rice husk, peanut shell, bagasse etc.).Wherein the content of cellulose of most of residue approaches hardwood, and minority approaches coniferous wood.Utilize these crop residues to make raw material, can produce wood-based plate fully, the consumption of wood material in China's wood-based panel industry is reduced.Thereby effectively alleviating the imbalance between supply and demand of timber resources, also is pressing for and the important channel of high-quality and efficient agricultural of development and help farmer richness.The exploitation of stalk plate had both reduced the loss to the forest resources of the modern life and industry, had remedied the vacancy in modern environment-friendly type plank market again, the demand of having catered to market.
What use when the raw materials for production initial stage handles in the prior art is a kind of hay cutter, raw material is cut into the size of requirement with two choppers of asynchronous behavior, this equipment has two very big shortcomings: 1. production efficiency is low, the ability feeding was to equipment after the workman need break up the raw material stalk even tiling, maximum super only 1 ton/hour for the treatment of capacity, the treating capacity of unit interval does not satisfy the demand of back segment operation; 2. handle of low qualityly, because the characteristic of the grass of raw material stalk, measure greatly and fragmentaryly, the chopper chaffcutter is difficult to accomplish the length dimension unanimity, and difference is also very big, is difficult to satisfy the back segment operation in qualitative requirement.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of be used to be exclusively used in wheat straw or rice straw coarse crushing device.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of stalk coarse crushing device, be characterized in: it is provided with the material storage tube of a band feeding device, the material storage tube middle part vertically is provided with a rotating shaft, a revolving cylinder is housed in the rotating shaft, be fixed with on the revolving cylinder and pull out stalk, have feed opening below the material storage tube, be provided with a pulverizing chamber over against feed opening, be provided with the swivel mount of a driven by motor in the pulverizing chamber, some hammer leaves are housed on the swivel mount, around swivel mount and the bottom screen cloth is housed, be provided with the discharging scraping plate conveying device below the pulverizing chamber.Wheat straw or straw enter in the material storage tube by the charging belt conveyer, rotation by revolving cylinder, it is broken up, material is sent into feed opening pulling out under the stalk effect, in pulverizing chamber, to expect that by the rotation hammer leaf grass meal is broken, broken grass up to specification drops on the discharging drag conveyor and transports from the hole of screen cloth, enter next process.
The technical problems to be solved in the utility model can also come by the following technical programs further to realize that feed opening is opened the side in the material storage tube bottom.
The utility model compared with prior art structure is comparatively simple, its advantage is: 1. treatment effeciency height, because after the grass that will pack unpacks, just do not need manually to break up and transport directly in the material storage tube of Roughpulverizer by belt conveyor, break up through the rotation of revolving cylinder again and evenly distribution, entering feed opening continuously pulverizes by hammer leaf, can obtain the broken forage of different sizes with different screen clothes, very convenient quick, treating capacity can reach 3.5 tons/hour under the normal condition, can satisfy year requirement of production 1.5 ten thousand stere sheet materials; 2. handle the quality height, because grass is to carry out continual even mixing by mechanical rotating cylinder, enter feed opening with fixing speed, the speed of hammer leaf also is constant in the unit interval, the hammer leaf of high speed rotating can evenly be smashed grass completely, obtains whole satisfactory particles by screen cloth; 3. can also remove a part of impurity in smashing process, further improve the quality of forage, 4. device structure is simple and reliable, can continuous uninterrupted work.
