Rice husking machine core capable of replacing husking blades

Abstract

The invention discloses a rice husking machine core capable of replacing husking blades. The rice husking machine core comprises a machine core body, a work section, a feed thread, the husking blade I, the husking blade II and a blocking thread. The feed thread is integrally formed on the machine core body. The blocking thread is integrally formed at the top end of the machine core body. The feedthread and the blocking thread are reverse threads. The work section is arranged on the part, between the feed thread and the blocking thread, of the machine core body and is provided with the huskingblade I and the husking blade II. The rice husking machine core is simple in structure, easy to machine and low in manufacturing cost, the husking blades liable to abrasion can be independently manufactured with environment-friendly good-abrasion-resistance hard materials, replacement is convenient, service life of the whole machine core part is prolonged greatly, economic and environmental protection benefits are significant, the structure of the machine core is improved, machining is facilitated, mechanical properties are also improved effectively, manufacturing cost is low, and practicability is high.

Description

technical field [0001] The invention belongs to the field of food processing, in particular to a rice shelling core with replaceable shelling blades. Background technique [0002] Rice has a long history as the main food of people. For a long time, people have experienced a long history of invention in order to remove the husk of rice and obtain edible rice. In the Neolithic Age in China, rice was pounded with pestles and stone mortars. From pounding rice to rice hulling, Then the rice is hulled first, and then the rice is husked to remove the rice husk. Today's technology is to first hustle the rice, separate the rice from the husk, and then grind the brown rice into white rice. This basic process is still used by the rice milling industry today. From 1905 to 1908, the horizontal rice mill (friction type) and emery rice mill (grinding type) were invented successively, which improved the precision of rice. In 1956, the air jet rice mill came out. The above three rice mills...

AI Technical Summary

Problems solved by technology

The above-mentioned equipment has high power and complex process flow, and is suitable for industrial production

[0003] It is a small paddy rice milling machine suitable for family use after improvement of the above horizontal rice milling machine. The main component of the paddy shelling machine is reduced from the traditional horizontal rice milling machine shelling machine core. Its structure remains unchanged. The core is It is made of integral steel, and the working blade, rotary blade, and mandrel are of the same material with low hardness, high cost, and difficult processing. Especially, the working blade and rotary blade will be scrapped once the core is worn out, which does not meet the energy-saving requirements.

[0004] In the current machine structure of the above-mentioned paddy rice milling machine, there are problems of difficult processing, high cost and short life;

[0005] Shell movement of traditional structure, see attached Figure 4 As shown, the straight blade 41, the helical blade 42, and the inner cylindrical surface 43 must be processed on a four-axis machine tool. The processing technology is complicated, the working hours are long, the energy consumption is large, and the cost is high.
