Description
Technical field
The utility model relates to the jet-air rice polisher design, especially makes things convenient for the jet-air rice polisher of tape swapping.
Background technology
Rice mill is the key equipment of paddy process equipment, in complete set of rice milling equipment brown rice is ground into rice, and at present the maximum of usefulness are the iron roll jet-air rice polishers.Brown rice is entered in the husk rice body by hopper, under the effect of spiral propeller, enter the husk rice chamber that rice milling roller, rice huller screen and pressure door are formed vertically, be subjected to the influence of outlet pressure door resistance, make between the brown rice grain and produce pressure, under the effect of rice milling roller muscle and rice huller screen surface configuration, grind mutually and wipe peeling.Simultaneously, the high-pressure blast of spray wind blower fan ejection is sprayed onto by the jet-air slot of rice milling roller through the main shaft endoporus and grinds the grain of rice of wiping peeling, has both strengthened the pearling of rice, has taken away the heat that part produces in the pearling process again, rice bran is discharged through rice huller screen with high-pressure blast, grinds good rice and flows out from pressure door.The quality of husk rice and output comprise degree of crushing (broken rice rate), the energy consumption (ton-grain power consumption) of rice, regulate relevant with the rice huller screen structure with the pressure of pressure door.And spray wind blower fan sprays into the effect that the air quantity of rice milling machine principal axis endoporus plays key.The form of main shaft air intake has two kinds: 1, enter from main shaft endoporus rear end and be air inlet through hollow shaft.2, the radial hole that communicates with the main shaft endoporus from rear-end of spindle enters and is air intake radially.In general, same spray wind blower fan air inlet through hollow shaft wants specific diameter much bigger to the air quantity of air intake.The jet-air rice polisher of Cun Zaiing mainly contains N, NPS, SN, MNMP and 6NF series in the market.Wherein N, NPS, SN, MNMP rice mill are air inlet through hollow shaft, but the air outlet and the main shaft endoporus that spray the wind blower fan have 90 ° of angles, and air intake efficiency is poor, and the belt pulley of transmitted power is installed in the centre of main shaft two bearings.As you know, in machine driving, bead apex is that consumable accessory will in time be changed.This structure will be dismantled main shaft when changing bead apex, has not only bothered but also influenced the precision of rice mill.Though 6NF series rice mill is changed into rear-end of spindle to belt pulley, is convenient for changing bead apex.But radially the structure of the air intake air quantity that makes spray wind blower fan spray into the main shaft endoporus also is subjected to very big the influence.
Summary of the invention
The purpose of this utility model provides a kind of jet-air rice polisher that makes things convenient for tape swapping, can obtain maximum intake, and it is convenient to change bead apex.
The technical scheme that its technical problem that solves the utility model adopts is: adopt the form of air inlet through hollow shaft, the air outlet of spray wind blower fan directly is connected with the rice milling machine principal axis endoporus through air guide structure.Belt pulley is installed in rear-end of spindle, and the air guide structure between spray wind blower fan and the main shaft is easy to loading and unloading.
Make things convenient for the main shaft of the jet-air rice polisher of tape swapping to be installed on the antero posterior axis bearing of casing, power imports into by the belt pulley that is installed on the main shaft, and high-pressure blast enters the husk rice chamber from the main shaft endoporus.The belt pulley of rice mill is installed in the outside of rear bearing block on the main shaft by key, be installed in bolt third on the belt pulley hub withstand on tightly key above, nut is with bolt third locking; Bent plate is installed on the side of rice mill box back, and spray wind blower fan is installed in above the bent plate by its bottom surface, and the air outlet of spray wind blower fan is coaxial with the endoporus of main shaft air intake; The endoporus of guide disc rear end is installed on the spray wind blower fan with on the coaxial external diameter of fan outlet and fixes with a plurality of bolt first and corresponding spring washer, the big endoporus of seal disc rear end is installed on the external diameter of guide disc front end and fixes with a plurality of bolt second and corresponding spring washer, the endoporus of guide disc rear end is coaxial with the external diameter of guide disc front end, the little endoporus of seal disc is installed on the cylindrical of rice milling machine principal axis upper belt pulley outside, two felt sealing rings and a rubber seal are installed between seal disc and the main shaft, and the length a of guide disc is less than the air outlet of spray wind blower fan and the distance b between the rice milling machine principal axis.
This makes things convenient for the advantage of the jet-air rice polisher of tape swapping to be: the high-pressure blast that spray wind blower fan produces directly is blown into the rice milling machine principal axis endoporus from air outlet through air guide structure, so the air intake efficiency height, air quantity is big.The air guide structure convenient disassembly helps the replacing of bead apex.
