When the connecting rotating ring 108 drives the connecting plate 1051 to rotate, the rotation control block 1052 rotates inside the rotation control groove 1053 to stably control the connecting plate 1051, and stably rotate and scrape for cleaning.

[0033] The working principle and usage process of the present utility model: For this kind of rice processing and grinding equipment, before use, first place the grinding equipment main body 100 stably at the rice processing production position by contacting the ground with the base 101. When the grinding equipment main body 100 is powered on for processing, pour an appropriate amount of rice into the grinding chamber 102. The main motor 107 operates to drive the connecting rotating ring 108 to rotate. When the connecting rotating ring 108 rotates, it drives the grinding roller 105 to rotate inside the grinding chamber 102. At the same time, the auxiliary motor 106 operates to drive the grinding roller 105 to rotate, so that the two grinding rollers 105 rotate relatively to grind the rice. Then, the grinding roller 105 rotates at different positions inside the grinding chamber 102 for grinding. Finally, after grinding, it falls through the screening holes into the inside of the blanking body 103, and then falls through the blanking body 103 into the inside of the collection box 104 to collect the rice flour;

[0034] Then, when the grinding equipment main body 100 is in processing and production, and the grinding roller 105 rotates for grinding treatment, when the grinding roller 105 grinds and extrudes rice, it is easy to cause a large amount of rice flour to adhere to the surface of the grinding roller 105. At this time, when the grinding roller 105 rotates for grinding, the surface of the scraping plate 1054 contacts the surface of the scraping plate 1054 to rotate and scrape off the rice flour adhering to the surface. At the same time, when the connecting rotating ring 108 drives the grinding roller 105 and the connecting plate 1051 to rotate, the connecting plate 1051 drives the rotating control block 1052 to rotate inside the rotating control groove 1053 when it rotates, making the connecting plate 1051 and the scraping plate 1054 rotate more stably to scrape and clean, facilitating the scraping and cleaning operation of the grinding roller 105 during the grinding treatment, effectively grinding the grinding roller 105, and improving the convenience and grinding effect of scraping and cleaning the grinding roller 105 when the grinding equipment main body 100 processes and grinds rice;

[0035] Finally, when the grinding equipment main body 100 processes and grinds rice, when the ground rice agglomerates and is at the inner bottom end of the grinding bin 102, when the grinding roller 105 rotates for grinding operation, it drives the mounting seat 1021 and the mounting plate 1022 to rotate. When the mounting plate 1022 rotates, it drives the crushing rod 1023 to rotate at the inner bottom end of the grinding bin 102, and the grinding roller 105 rotates at different positions inside the grinding bin 102, which is easy to rotate and crush the agglomerated rice flour at different positions inside, and discharge it smoothly through the screening holes, improving the convenience of crushing, screening and discharging during the rice processing and grinding of the grinding equipment main body 100, and effectively grinding and processing.

[0036] Although the embodiments of the present invention have been shown and described (see the above detailed description), for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
