Abstract

The utility model relates to a micro-rice-hulling machine, which is mainly used for rice processing for farmers. The utility model adopts a vertical structure. A rice roller is directly connected with a motor by a flange disk. The utility model has the advantage of convenient assembly and disassembly. Segment grinding ribs of different spiral angles are arranged on the rice roller to make the pressure in a whitening chamber be reasonably distributed. Besides, the broken rice rate and the phenomena of discharging blocking are reduced. The inner side of an upper cover plate of a machine casing is provided with a wear resistant sleeve. The wear resistant sleeve not only protect the machine casing, but also improve the reliability and stability of the utility model. The pressure regulation of a discharging door adopts a screw spring type. The regulation range is more flexible and proper.

Description

Micro-rice-hulling machine

The utility model relates to a kind of Micro-rice-hulling machine, is used for the processing of peasant household's rice.

November 1 nineteen sixty, fourth wood aimed at together on " test tube newspaper ", and in " discussion of China's rural area rice milling machinery selection issue " literary composition, meter machine of introducing has the branch of vertical rice machine, horizontal rice machine.Nineteen ninety, Hunan Ningxiang County metal forming machinery factory produced a kind of family expenses rice machine that adopts single-phase 220V power supply, the vertical layout of rice machine pearling device, because problem is more on the structure, bad use is promoted few.

China's patent 91212722.8 discloses a kind of name and has been called the vertical iron roll separator of family expenses, on the structure than previous crops bigger improvement, have load simple in structure gently, advantage such as vexed car not.But imperfection still on this rice machine structure, still there are some problems in the use, as everyone knows, the rice roller is the core component in meter machine, it is being undertaken paddy and is going chaff shell and brown rice to grind into the dual role of rice, and stone roller muscle on this product rice roller and the general the same helical angle that adopts single angle of rice machine, because (power is little for the particularity of this rice machine, rice roller little and vertical) thereby processing rice rice containing amount and broken rice rate not fully up to expectations, grind muscle and all adopt muscle, it is bigger than normal to go out meter resistance, go out Mi Buchang, the reliability that influence is used, rice roller lower end directly is sleeved on the motor shaft, and not supporting of upper end, thereby the length of socket should be grown as far as possible, and motor is also suitable tight with cooperating of rice roller hole, the rice roller may wear to a certain degree after work a period of time and promptly need change, and dismounting is got up very difficult, have in disassembly process in addition damage motor.In addition, the direct and processed paddy seed of casing upper cover plate contacts friction, wearing and tearing easily, and discharge door pressure is regulated and is adopted the weight Model type adjusting, and the scope of adjusting does not satisfy requirement sometimes.

The purpose of this utility model is to provide a kind of more reasonable structure at above-mentioned technical deficiency, and it is more reliable to work, more excellent performance, and dismounting, Micro-rice-hulling machine easy to adjust.

The utility model is achieved in that meter roller and motor adopt ring flange to connect, and the rice roller grinds muscle and adopts the different helical angle structures of segmentation, and the helical angle that hypomere grinds muscle is 0-6.5 °.The casing upper cover plate madial wall of the whitening chamber that constitutes at casing upper cover plate and rice huller screen, rice roller has wearing bush, discharge door pressure is regulated and is adopted screw spring device, the end and the adjustment screw seat that are spring are fixed on the casing, the other end of spring is pressed on the discharge door, and adjustment screw is contained on the adjustment screw seat.

Accompanying drawing is the front view of a kind of embodiment of the utility model.

Now illustrate in detail with regard to structure of the present utility model and operation principle in conjunction with the accompanying drawings:

The utility model mainly is made up of hopper 1, rice roller 2, wearing bush 3, casing 4, ring flange 8, sieve sheet 15, rice cutter 16, motor 9, separator 10, discharge door 11.The ring flange 8 of rice roller 2 through connecting with motor 9 with key connects by screw 7 and motor 9, so not only can reduce the total length of meter roller, and dismounting rice roller 2, only need screw off screw 7, can realize easily.On having at least on the rice roller 2, grind muscle 5 and grind respectively 2 in muscle 6 down, the spiral of last stone roller muscle 5 greater than under grind muscle 6 helical angles, during the work of rice roller, the pressure top that forms in the whitening chamber of formations such as rice roller 2 and rice huller screen 15 is bigger, the bottom is less, can reduce broken rice rate effectively and reduce rice and discharge the outer resistance of machine, improve the reliability of facility work, following helical angle of grinding muscle be 0-6.5 ° comparatively suitable.

With processed paddy seeds friction wear and tear directly in order to overcome casing upper cover plate 17 that (operating pressure is big herein, very easily wearing and tearing), influence the stability of facility serviceability, constitute whitening chamber between casing cover plate 17, rice huller screen 15, the rice roller 2, there is wearing bush 3 casing upper cover plate 17 inboards, after wearing bush 3 may wear to a certain degree, take off replacing.Wearing bush also can be made into inwardly protruded some semicircle salient points, and since the effect of salient point, the easier here broken shell of paddy, thus improve rice machine operating efficiency.

The utility model discharge door pressure adjusting changing weight Model type gravity is adjusted to the screw spring formula and regulates, enlarged adjustable range, the end and the adjustment screw seat 13 that are spring 12 are fixed on the casing 4, the other end of spring 12 is pressed on the discharge door 11, adjustment screw 14 is contained on the adjustment screw holder 13, rotation adjustment screw 14 can change the pressure of 12 pairs of discharge doors 11 of spring, and then reaches the pressure that regulate to change in the whitening chamber, goes out Mi Jingdu and go out the purpose of Mi Zhiliang.

The utility model can also be made the little taper of the big discharge end of feed end with sieve sheet 15, and the end of rice roller 2, is cylindrical through making, thereby distributions that hold water of operating pressure in the assurance whitening chamber reaches the purpose of pearling, also improved the processing technology of rice roller and meter roller die tool simultaneously.

The utility model is work like this, rice roller 2 rotates under the drive of motor 9, paddy pushes away under the effect of muscle in deadweight and rice roller top from hopper 1, enter in the whitening chamber equably, at the sieve sheet, the rice cutter, finish husk and pearling work under the acting in conjunction of rice roller, thin chaff is outside sieve film perforation discharge machine, rice, crack rice, chaff is discharged from different outlets after separator separates, because stone roller muscle segmentation setting on the rice roller and epimere grind the muscle helical angle is ground muscle greater than hypomere helical angle, ring flange is adopted in the connection of rice roller and motor, in casing upper cover plate installed inside wearing bush is arranged, discharge door pressure is regulated and is adopted the screw spring, thereby more general vertical rice facility have more reasonable structure, it is more reliable to work, performance is more stable, dismounting, regulate advantages such as more convenient.
