Description

Combined type grain descaling machine

The utility model belongs to agricultrue sideline production processing machinery, relates to a kind of grain descaling machine.

At present, the vast rural area of China, before processing flour, to the cleaning of grain, many places are still picked up, are eluriated based on artificial sieve, and also useful rice mill replaces clear grain, can only remove light miscellaneous material, still needs artificial to removal and the profit water of sandstone.A kind of flour processing special manufacturer's matching used " grain descaling machine " that is is arranged on the market recently, and structure as shown in Figure 5.Storage bin(hopper) (10) is installed in above the three-deck vibrating screen (50), go stone device (40) to be positioned at central rack, drive by eccentric stiffener, blower fan (30) is arranged on the below of stone device, go the mouth of putting out cereal of stone device to join with the mechanism (20) of threshing wheat, threshing wheat has vibratory sieve (50) below the mechanism, and horizontal profit water device (60) is installed on the ground.This grain descaling machine takes off, goes stone, screen, profit water function though have to beat because complex structure, bulky, inconvenient operation, seriously polluted, power consumption is many, price is expensive, so is not suitable for the wide farmers use.

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of combined type grain descaling machine is provided, not only collection beats that to take off, go stone, screen, profit water function be one, and have rationally distributed, simple in structure, volume is little, easy to operate, advantage that cleaning effect is good, be more suitable for peasant household and use.

The utility model is achieved through the following technical solutions its purpose.A kind of combined type grain descaling machine comprises: storage bin(hopper), vibratory sieve, by the motor transmission thresh wheat arbor drive the braces rotation the mechanism of threshing wheat, by motor transmission stone remover axle drive the eccentric block rotation remove the stone device, by the blower fan and the spiral profit water device frame of motor transmission.Its thresh wheat mechanism bin stock with go between the stone device and be communicated with.Its blower fan is positioned at the top of stone device, is communicated with the outer cover that removes the stone device with air intake cover.It goes the eccentric block of stone device to make scale type sieve plate pitching by pull bar, and the fish scale sieve plate is hinged by strut and frame.Its vibratory sieve is positioned at the below of fish scale sieve plate, and is fixed together, and also drives vibratory sieve and move together when the sieve plate pitching.There is Selected Room in the place ahead of fish scale sieve plate, and the following horizontal direction of Selected Room is provided with plug-type air regulating board, and width adjustment plates is set in stone outlet hole.Its spiral profit water device vertically-arranged is in the outside of frame, and the spiral of helix tube central authorities is by the bevel gear transmission of stone remover axle head, and is communicated with water pipe at the helix tube middle part, the top of the helix tube mouth of putting out cereal.In order to make compact conformation, available sheet is connected between the outer cover of the air intake cover of blower fan and stone remover structure.

Compared with the prior art the utility model has the following advantages:

1, since the mechanism of will threshing wheat be arranged on storage bin(hopper) and go between the stone device, blower fan is arranged on the top of stone device, therefore, grain earlier through the mechanism of threshing wheat beat enter again after taking off ditch soil, clever shell, small ear, the awn of wheat be negative blast remove the stone device, light weight sundries is sucked out outdoor.Not only can save the vibratory sieve below the mechanism of threshing wheat, the three-deck vibrating screen that changes the top complexity is the bottom single-deck vibrating screen, thereby the complete machine height is reduced greatly, simplify the structure, and this elder generation beats the technology advanced person who takes off the back screen, can improve cleaning effect, improves flour quality.

2, because the rational deployment of blower fan makes the stone process be in negative pressure state, and wind enters from fish scale sieve plate bottom, the grain on the sieve plate is suspended, utilize the proportion difference that stone is winnowed with a dustpan out, this negative pressure goes stone effective.Below Selected Room, be provided with plug-type air regulating board in addition and in stone outlet hole, be provided with width adjustment plates, can regulate the air quantity size, go the stone effect thereby improved effectively according to various situations of change such as grain kind, inlet amount, sieve plate density.Simultaneously, the negative pressure operation is than the few air pollution of malleation operation.

3, owing to take vertical profit water device, can realize that not only the bevel gear transmission simplified transmission device, and grain is risen to certain altitude, greatly facilitate the operation that connects grain, alleviated labour intensity.

In a word, the utlity model has reasonable in design, simple in structure, machine volume is little, easy to operate, advantage that cleaning effect is good, can clear up grains such as wheat, corn, beans, is fit to the supporting use of small-sized cornmill.

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
