Description

Technical Field

[0001] The utility model relates to the technical field of primary processing of rice, in particular to a stone removing device for primary processing of rice. Background Art

[0002] Rice is one of the most important food crops in the world today. More than half of the world's population relies on rice as their main food source. Rice is not only a staple food, but also has many economic functions that contribute to mankind after a long history of evolution. During the harvesting and processing of rice, stones will be mixed in, which will affect the processing of rice. Therefore, the stones in the rice need to be removed during the initial processing of rice.

[0003] A Chinese patent discloses a stone removal device for rice processing (Announcement No. CN219401126U). The patented technology can screen smaller stones and larger stones in rice to reduce the stone content in rice. It can also generate a wind field inside the base to blow the filtered rice so that an equal volume of rice is blown to the left side of the bending plate and the stones are located on the right side of the bending plate, thereby effectively removing the stones from the rice. The stone removal box can also be buffered to prevent the stone removal box from being too impacted and causing the stone removal box to deviate from its original motion trajectory.

[0004] However, there are still some shortcomings in this patent. Although this patent can remove stones from rice, it can be seen from the drawings of this patent that this patent cannot quickly discharge the rice after removing stones, resulting in a decrease in the subsequent stone removal efficiency, affecting the processing of rice. Therefore, those skilled in the art provide a stone removal device for primary processing of rice to solve the problems raised in the above background technology. Utility Model Content
