[0014] ① The present invention provides a linkage rice milling and crushing machine, which integrates a rice mill and a crushing machine, and can independently complete the rice milling and crushing functions, and also have a mutual dependence. After starting, the two machines are linked to achieve complementary functions and give full play to the maximum effect of their shared power;

[0015] ② Most of the machine casings are changed from cast iron to steel stamping die structure to reduce the weight of the machine body; the structure is reasonably set up, the machine structure is compact, the production cost is reduced, the processing efficiency is improved, the operation is simple, and it is easy to use.

[0016] ③Only one lower hopper for rice milling and crushing is installed on the upper end of the machine body, which reduces the weight of the whole machine and the difficulty of installation, saving the cost of raw materials;

[0017] ④ The crushing mechanism component can not only realize its own crusher function, but also realize the rice bran separation function for the rice mill through the cyclone generated by rotation, sucking the bran, broken rice, dust, impurities, etc. into the crusher cavity for secondary processing, thereby improving the working efficiency of the whole machine;

[0018] ⑤ The installation chamber of the crushing mechanism is connected to the lower end of the rice milling chamber through an inclined chute. The material passes through the outer chamber of the rice screen of the rice milling machine and enters the crusher chamber through the inclined chute. The suction air generated by the crushing mechanism sucks the bran and dust of the rice milling mechanism into the crusher chamber, effectively avoiding the accumulation of materials in the machine;

[0019] ⑥ The double bearing bodies of the rice mill and the crusher are both located outside the housing and correspond to one end of the pulley below the feed port. The rotating roller passes through the double bearing body and enters the rice milling component cavity and the crushing component cavity to work, which is convenient for overall assembly;

[0020] ⑦ The outer cavity of the rice mill component is changed to a steel stamping die structure, which effectively reduces the weight of the whole machine. At the same time, the rice screen fixing cavity fixes the rice screen more firmly, effectively preventing rice leakage due to loose rice screen;

[0021] ⑧The gear-type rice output regulator is very easy for users to operate. It not only effectively adjusts the working pressure of the rice machine and controls the rice output quality, but also makes the appearance of the whole machine more perfect. BRIEF DESCRIPTION OF THE DRAWINGS
