Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of stalk lapping device.
Background technology
Stalk as feed applications be in animal husbandry 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 go to Northern Europe education according to a collection of young expert of agreement China sent, 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 had arranged 10 stalk cowboying demonstration counties then.From then on, China's cattle-raising is through with and develops comparatively slowly situation decades, enters the new period of high speed development.Subsequently, State Council determines, copies the way of stalk cowboying demonstrative project to implement the stalk sheep raising in the whole nation, supports buffalo and foster milk cow demonstrative project.So far, " straw animal " begins to form, and becomes the policy of country and the practice of vast farmers, obtaining huge achievement aspect economy, ecology and the social benefit.Under the drive of stalk stock keeping demonstration project, by promoting the technology such as straw ensiling, ammonification, little storage, the feeding total amount of national stalk reached about 200,000,000 t 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 in 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 need to grind as the raw material of feed, 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 is different, directly grinds to cause thickness uneven, and easily damages blade.
As disclosing a kind of energy-efficient stalk crasher in the patent [application number: 201010197888.4], mainly by motor, frame, the upper casing combination, the lower casing combination, hammer leaf rotor portions dress, intake mechanism, walking mechanisms etc. partly form, it is characterized in that being provided with feeding unit and hammer leaf rotor portions dress at the feeding mouth place of pulverizer is fixed on the motor reel, thereby having solved stalk causes power to change the greatly low disadvantage of generation rate because feeding inequality, realized the hope that transmission efficiency simple in structure is high, reached energy-efficient purpose, but, ground by hammer leaf, it is relatively poor that it grinds the uniformity.
Summary of the invention
The objective of the invention is the problems referred to above for existing technology existence, a kind of stalk lapping device is provided, technical problem to be solved by this invention is how stalk to be ground to form uniform powder.
Purpose of the present invention can realize by following technical proposal: a kind of stalk lapping device, comprise support, it is characterized in that, be fixedly installed refined structure and the abrasive structure that is positioned at described refined structure lower end on the described support, described refined structure comprises a housing, described housing upper end is provided with a spout, has a corase grind chamber in the described housing, be provided with a cutting-cylinder in the described corase grind chamber, be fixedly installed some cutting knife on the described cutting-cylinder, has a fine grinding chamber in the described cutting-cylinder, be provided with a fine grinding cylinder in the described fine grinding chamber, evenly be provided with some fine grinding teeth on the described fine grinding cylinder, be provided with the coarse strainer in UNICOM corase grind chamber and fine grinding chamber on the described cutting-cylinder, be provided with fie screen on the described cutting-cylinder; Described abrasive structure comprises a funnel that connects material that is positioned at the fie screen lower end, and the described funnel that connects material communicates with the inner chamber of a sand cylinder, is provided with several abrasive rollers in the inner chamber of described sand cylinder, also is provided with the blanking filter screen on the described sand cylinder; Described cutting-cylinder is driven by a drive motors, is linked to each other by a transferring structure between described drive motors and the described abrasive roller.
Operation principle of the present invention is: stalk is added by spout, cutting knife cutting through rotating also has cutting knife drive stalk to move in the corase grind chamber, until move to the coarse strainer place, enter the fine grinding chamber, cut again and grind that (the fine grinding cylinder is fixed on the support by the fine grinding cylinder in the fine grinding chamber, its relative cutting-cylinder rotation, stalk is again cut and grinds), when the coarse strainer that screws on when cutting-cylinder moves to the cutting-cylinder lower end, stalk is fallen in the corase grind chamber between cutting-cylinder and the housing by coarse strainer, if the degree of refinement of stalk meets standard, then leached by the fie screen place, the stalk that can not leach is then again driven by cutting knife and enters the fine grinding chamber, and so circulation is until degree of refinement meets leaching till the condition of fie screen; Fall into from the broken end of stalk that fie screen leaches and to connect material funnel and to enter the inner chamber of sand cylinder, ground by abrasive roller, until after reaching the target degree of refinement, leach from the blanking filter screen.
In above-mentioned a kind of stalk lapping device, described abrasive roller have two and mutually against, described two abrasive rollers are connected with a planetary gear respectively, described two planetary gears are intermeshing; Described planetary gear links to each other with a rotating cylinder with ring gear; Described two planetary gears all with the engagement of the ring gear of rotating cylinder.Drive motors drives the rotating cylinder rotation, two planetary gears of drive and the engagement of rotating cylinder ring gear are in the intermeshing while, also rotate along ring gear, two planetary gears link to each other with two abrasive rollers respectively, two broken ends of the mutual straw extrusion of abrasive roller make it grind into powder, simultaneously two abrasive rollers also in sand cylinder along the center revolution of sand cylinder, stalk is stirred, make can't again be polished from the stalk that the blanking filter screen leaches cylinder and grind.
In above-mentioned a kind of stalk lapping device, described drive mechanism comprises a belt pulley that is installed on the drive motors output shaft, and described rotating cylinder outer rim is provided with belt grooves, links to each other by driving belt between described belt grooves and the belt pulley.Drive motors when driving cutting-cylinder and rotating, by driving belt with transmission of power to rotating cylinder, thereby be passed to two abrasive rollers; The external diameter of rotating cylinder is much larger than belt pulley, and rotating cylinder obtains to compare the much bigger rotating speed of cutting-cylinder.
