Abstract

The utility model proposes a mound pressing rice mill, which is characterized in that two bearing pedestals are respectively supported by the roller axises of rice milling rollers on both sides so as to improve the stress condition of rice milling roller at work. The inner wall of the machine cover is tooth like so as to upgrade milling and rinding effects, production efficiency and machining quality. The axis of the whitening chamber is to regulate lock gate through cardinal axis in discharge hole of end wall and connected with the screw with mound pressing nut for adjusting lock gate so as to assure fluent movement of material, and the mound pressing nut already preset automatically adjusts the opening degree of lock gate so as to assure rice quality.

Description

The ram rice mill

The utility model relates to the agricultural machinery that a kind of grain milling processing is handled, and specifically a kind of ram rice mill is specially adapted to vast rural area peasant family and uses.

In general, edible rice goes the chaff two procedures to be processed into through husk rice shelling and selection by winnowing paddy, at present, in vast agricultural district is to utilize waterpower or electric power earlier the paddy husk rice to be shelled, the rice that will make again, the chaff mixture concentrates selection by winnowing to remove the purpose that the chaff material is realized selected rice, this traditional operating type is time-consuming, labour intensity is big and production efficiency is low, recently the weight Model type rice function that adopts realizes that husk rice shelling simultaneously and selection by winnowing go the work continuously purpose of selected rice of chaff two procedures, but there are some technological deficiencies in this traditional weight Model type rice machine equipment: the support pattern of its husk rice roller is an end that bearing block is installed in the husk rice roller, cause husk rice roller rotary work under abominable cantilever position, the bearing working inclement condition, shortened the working life of bearing greatly, the less stable of rice machine work, increased the maintenance management expense, secondly, the rice output outlet of traditional weight Model type rice machine is the radially discharging along the husk rice roller, make material movement not smooth, particularly its discharging opening is to adopt a plate to adjust Mi Liuliang, thisly often need repeatable operation repeatedly just can mix up by manually-operated plate regulative mode, troublesome poeration not only, and have a strong impact on out Mi Zhiliang.

The purpose of this utility model be a kind of reasonable in design, simple to operate, good mechanical property is proposed on the basis of existing technology, the maintenance management expense is low, reliable working performance stable, goes out the ram rice mill that Mi Zhiliang is good, production efficiency is high.

The purpose of this utility model is achieved by the following technical solution:

A kind of ram rice mill, it mainly is made of the frame that motor is installed, the square chest that is installed on frame, the cover that feed hopper is installed, the roll shaft that rice milling roller is installed, bearing block, the thin chaff suction pipe that is installed on the negative pressure blade of roll shaft and is communicated in negative pressure chamber, the cover and the square chest that are connected in square chest constitute whitening chamber, be installed with big chaff sieve in the whitening chamber, big chaff sieve place is equipped with big bran outlet, it is characterized in that; The hinged regulating gate that is equipped with in the discharging opening place that the axial end wall of whitening chamber is done, the screw rod that is fixedly connected on regulating gate is fitted with the ram nut, can make the material movement smoothness, extent of opening by the automatic regulating gate of ram nut that configures, thereby control out Mi Liuliang, guarantee Mi Zhiliang, the polished rice discharging opening is installed below discharging opening, the other end connection of thin chaff suction pipe is installed on polished rice discharging opening sidewall, thin chaff suction pipe can be discharged the whole negative suctions of thin chaff chaff material chamber, the inwall of cover is made the groove shape, can improve the husk rice effect of peeling off, and enhances productivity and crudy.

The utility model also has following technical characterictic:

Two bearing blocks that are installed on square chest are supported on the roll shaft place of rice milling roller both sides respectively, and force-bearing situation in the time of can improving rice milling roller work improves mechanical performance, prolongs working life, reduces the maintenance management expense.

The hinged installation regulating gate in the discharging opening place that the axial end wall of whitening chamber of the present utility model is done, the screw rod that is fixedly connected on regulating gate is fitted with the ram nut, can make the material movement smoothness, extent of opening by the automatic regulating gate of ram nut that configures, thereby control out Mi Liuliang automatically, guarantee Mi Zhiliang; Be supported on the roll shaft place of rice milling roller both sides respectively by two bearing blocks, the force-bearing situation in the time of can improving rice milling roller work, the service life of improving machinery; The inwall of cover is made the groove shape, can strengthen the husk rice effect of peeling off, further improve the production efficiency and the crudy of machinery.

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is the A-A figure (amplification) of Fig. 1,

Fig. 3 is the B-B figure of Fig. 1.

Below in conjunction with accompanying drawing the utility model is further described:

A kind of ram rice mill, it is mainly by the frame 1 that motor 2 is installed, be installed on the square chest 6 of frame 1, the cover 14 of feed hopper 10 is installed, the roll shaft 26 of rice milling roller 15 is installed,
