Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of stalk lapping device, particularly the refined structure in a kind of stalk lapping device.
Background technology
Stalk as feed applications in livestock breeding, be that stalk comprehensive utilization is with the longest history, one of most important mode.China's tissue improvement stalk is fed and is raised the research of value mainly since 20th century the mid-80.Subsequently, under the support of various places agricultural universities and colleges, scientific research institution, Technique Popularizing department, carry out small-scale pilot, demonstration.FAO (Food and Agriculture Organization of the United Nation) (FAO), United Nations Development Programme (UNDP) cooperated with the Ministry of Agriculture in 1987, beginning is implemented a collection of technological cooperation (TCP) project (Guo Tingshuan in China, 2003), wherein according to a collection of young expert of agreement China sent, go to Northern Europe education, the study stalk is processed and the stock keeping technology; Both sides also select the number county as stalk cowboying pilot in Hebei province and Henan Province two provinces.Through effort in 3 years, project obtained certain success.1991, animal and veterinary department of the Ministry of Agriculture just " stalk stock keeping " problem organized an academic great debate, and the status of " straw animal " tentatively is confirmed.1992, State Council determined to implement stalk stock keeping demonstrative project, and then, has arranged 10 stalk cowboying demonstration counties.From then on, China's cattle-raising is through with and develops situation comparatively slowly decades, enters the new period of high speed development.Subsequently, State Council determines, copies the way of stalk cowboying demonstrative project in the whole nation, to implement the stalk sheep raising, supports buffalo and foster milk cow demonstrative project.So far, " straw animal " starts to form, and becomes the policy of country and the practice of vast farmers, aspect economy, ecology and social benefit, obtaining huge achievement.Under the drive of stalk stock keeping demonstration project, by promoting the technology such as straw ensiling, ammonification, micro-storage, the feeding total amount of national stalk reached 200,000,000 t left and right in 2008, beef, mutton and milk crop rise to 6,100,000 t, 3,760,000 t and 3,651 ten thousand t by 1,800,000 t, 1,250,000 t and 5,030,000 t of 1992 respectively, increase respectively 2.39 times, 2.01 times and 6.26 times.16 large provinces of stalk stock keeping such as Anhui, Henan, Shandong, beef or mutton output accounted for respectively 83.5% and 85.7% of the whole nation in 2008.
Stalk, as the raw material of feed, need to grind, and the degree of refinement of its grinding is the key factor that determines feed quality; Because stalk comprises blade, root and stem, each position density and hardness difference, directly grind and certainly will cause the thickness inequality, and easily damage blade.
as in patent [application number: 201010197888.4], disclosed a kind of energy-efficient stalk crasher, mainly by electromotor, frame, the upper casing combination, the lower casing combination, hammer leaf rotor portions dress, intake mechanism, running gears etc. partly form, it is characterized in that being provided with at the feeding mouth place of cracker feeding unit and hammer leaf rotor portions dress is fixed on motor reel, thereby having solved stalk causes power to change the low disadvantage of generation rate greatly because feeding inequality, realized the hope that transmission efficiency simple in structure is high, reached energy-efficient purpose, but, by hammer leaf, ground, it is poor that it grinds the uniformity, the stalk thinning effect is poor.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for existing technology, and the refined structure in a kind of stalk lapping device is provided, and this refined structure has can be by the characteristics of stalk refinement more, good in refining effect.
the purpose of this utility model can realize by following technical proposal: the refined structure in a kind of stalk lapping device, described stalk lapping device, comprise support, be fixed on the housing on support, described housing upper end is provided with a spout, in described housing, has a corase grind chamber, in described corase grind chamber, be provided with a cutting-cylinder, on described cutting-cylinder, be fixedly installed some cutting knife, in described cutting-cylinder, has a fine grinding chamber, it is characterized in that, this refined structure is arranged in described fine grinding chamber, comprise a fine grinding cylinder that is arranged in the fine grinding chamber, described fine grinding cylinder is arranged on housing by the mode of axial restraint and circumferentially rotation, on described fine grinding cylinder, circumferentially evenly be provided with some fine grinding teeth, on described cutting-cylinder, be provided with fie screen, described fine grinding cylinder is driven by a drive motors.
In described fine grinding cylinder, wear and be fixed with a turning cylinder, described turning cylinder two ends all by bearing shaft to being positioned on described housing.
On the output shaft of described drive motors, be fixed with drive pulley, on described turning cylinder, be fixed with driven pulley, between described drive pulley and driven pulley, be provided with belt.
As another situation, on the output shaft of described drive motors, be fixed with driving gear, on described turning cylinder, be fixed with driven gear, described driving gear is meshed with driven gear.
The inwall in described fine grinding cylinder and fine grinding chamber is tangent.The fine grinding cylinder is positioned at the below in fine grinding chamber, and the stalk gravitate that rolls in the fine grinding chamber falls to fine grinding cylinder and the contacted position of fine grinding cavity wall, thereby completes cutting again and the grinding to stalk.
On described cutting-cylinder, be provided with the coarse strainer in UNICOM corase grind chamber and fine grinding chamber.
Compared with prior art, the utility model is by circumferentially evenly being provided with some fine grinding teeth on the fine grinding cylinder, and the fine grinding tooth is tangent with the inwall in fine grinding chamber, therefore, can be by stalk refinement more, good in refining effect, improved the availability of stalk.
