Description

TECHNICAL FIELD

[0001] The utility model relates to rice processing technical field, specifically, a rice processing impurity and stone removing machine. BACKGROUND

[0002] Rice processing refers to the processing procedures such as cleaning, hulling, milling and product finishing of paddy, and one of the more important processes in the rice cleaning process is stone removal. Paddy contains a lot of impurities such as stones after harvesting. In order to improve the quality of rice and ensure the health of human consumption, a stone removing machine is needed to clean the stones and impurities contained in the rice.

[0003] There are many existing technologies for rice stone removing machines, for example:

[0004] Chinese patent publication No. CN218360635U discloses a rice processing impurity and stone removing machine, which comprises a screening box, a feed inlet is fixed on the upper side of the screening box, a discharge outlet is arranged on the right side of the screening box, and a foreign matter discharge port is arranged on the left side of the screening box. A pre-screening mechanism is arranged on the upper end of the feed inlet, the pre-screening mechanism comprises a screening unit, a rolling unit, an elastic unit, an electric telescopic rod and a knocking unit, the screening unit is inserted into the interior of the feed inlet at both ends, the rolling unit is arranged at both ends of the screening unit, the elastic unit is arranged at the lower side of both ends of the screening unit, the electric telescopic rod is arranged at the upper side of both ends of the feed inlet, and the knocking unit is arranged at the lower end of the electric telescopic rod. By arranging the pre-screening mechanism, the rice can be pre-screened when the stone removing machine processes the rice, which prevents large impurities from entering the stone removing machine and causing blockage, and effectively improves the screening efficiency.

[0005] The existing rice impurity and stone removing machine generally allows the rice to be screened when screening the stones in the rice, and the difference in weight and particle size between the stones and the rice is utilized to allow the rice with lighter weight and smaller particle size to pass through the screening mechanism, so that the stones with larger weight and particle size are intercepted by the screening mechanism. However, if the particle size of the stones is just able to be stuck in the screen hole, it will affect the subsequent screening of the rice. For example, the above-mentioned patent discloses a rice processing impurity and stone removing machine, which knocks the screen plate by the knocking unit. However, the stones shaken up may jump up and down in the screen hole, which still affects the subsequent screening.

[0006] Therefore, we propose a rice processing impurity and stone removing machine to improve the deficiencies of the existing technology. UTILITY MODEL CONTENTS
