Specification

Description:TECHNICAL FIELD
The present disclosure relates generally to grain processing machines. More particularly, the present disclosure provides a screw shaft for a grain processing equipment.
BACKGROUND
Grain processing equipment are generally used to process grains i.e., by removing the husk/chaff from the grains. Removal of chaff from the grains is generally termed as shelling of grains. There are various grain mills that perform shelling for the grains. But conventional grain mills are not good at production rates of the processed grains. Conventional grain mills are able to receive adequate quantity of grains but the grains are not processed at the required rate. This reduces the production quantity of the processed grains.
Since, the conventional mills are not able to process the grains at faster rates, therefore, the input quantity of the grains is maintained as per the production capacity of the mill. Also, the conventional mills are not able to process large quantity of grains at a time. In case, larger production quantity of the processed grains is required, then larger sized grain mills are required. Larger sized grain mills consume a lot of floor space and are difficult to carry from one place to another. Furthermore, larger sized grains mills require more components for processing the grains, which makes the overall structure of the grain mill very complex.
Therefore, there exists a need for an efficient grain processing equipment that is capable of solving aforementioned problems of the conventional grain processing equipment.

FIG. 3 illustrates a zoomed perspective view of the second portion 204 of the screw shaft 112 of FIG. 2, in accordance with an embodiment herein. Specifically, FIG. 3 depicts double pitch of the protruded thread 212. The double pitch of the protruded thread 212 may define double pitches i.e., a first pitch and a second pitch. The term “pitch” as used herein the context of the present disclosure refers to distance between corresponding points on adjacent threads of the protruded thread 212. The double pitch of the protruded thread 212 may include a first start point 302 and a second start point 304. The first pitch of the double pitched protruded thread 212 may start from the first start point 302 and the second pitch of the double pitched protruded thread 212 may start from the second start point 304. The double pitches of the protruded thread 212 transmit larger quantity of the grains toward the first and second set of blades 208A and 208B without increasing the size and diameter of the screw shaft 112. Therefore, the double pitches of the protruded thread 212 increases the feed quantity of the grains and allows to feed the grains in a faster manner without increasing/altering dimensions of the grain processing equipment 100. The double-pitches of the protruded thread 212 further reduces the time required for processing the grains and thereby increasing the production of the processed grains.

In operation, the rotational device 116 may rotate the outgrowth part 216 in the counter-clockwise direction. Upon rotation of the outgrowth part 216, the screw shaft 112 rotates in the counter-clockwise direction. The protruded thread 212 may be adapted to receive the grains from the hopper 104 when the feed plate 108 is in the open position. The protruded thread 212 may be adapted to lead the grains from the second portion 204 towards the first and second set of blades 208A and 208B of the first portion 202. The first and second set of blades 208A and 208B may be adapted to perform shelling of the grains i.e., the first and second set of blades 208A and 208B may be adapted to remove the chaff of the grains to produce processed grains. While the first and second set of blades 208A and 208B removes the chaff of the grains, the screen 106 prevents outspread of the chaff from the grain processing equipment 100. The processed grains may be guided towards the chute 118. The chute 118 may direct the processed grains out from the grain processing equipment 100. The chaff that is removed from the grains may be guided towards the first end 120A of the passage 120. The blower 122 may be adapted to suck the chaff from the first end 120A to the second end 120B of the passage 120. Upon suction of the chaff up to the second end 120B, the blower 122 may be adapted to eject the chaff out from the grain processing equipment 100.
Embodiments of the present disclosure are intended to include and/or otherwise cover another dimensional range for various elements of the grain processing equipment 100 without deviating from the scope of the present disclosure.
