The toggle mechanism 9 comprises a toggle rotating shaft 91, a toggle plate 92, a toggle motor 93, a transmission belt pulley 94 and a transmission belt 95, the toggle rotating shaft 91 is uniformly installed on the inner wall of the transmission groove 5 through a bearing, the toggle plate 92 is uniformly installed on the outer side surface of the toggle rotating shaft 91 along the circumferential direction of the outer side surface, the toggle motor 93 is installed at the front end of the toggle rotating shaft positioned at the left side of the transmission groove 5, the toggle motor 93 is installed on the front side surface of the transmission groove 5 through a motor base, the transmission belt pulley 94 is installed at the rear end of the toggle shaft, and the transmission belt pulleys 94 are; when the transmission band 24 transmits the rice, the output shaft of the stirring motor 93 rotates to drive the transmission belt wheel 94, the transmission belt 95 and the stirring plate 92 to rotate rightwards by stirring the rotating shaft 91, and the rice on the transmission band 24 can be stirred when the rice is stirred to rotate rightwards, so that the rice flattening effect can be increased.

According to the rice cooling device, the cooling block 6 can be used for cooling the rice at the lower layer of the conveying belt 24, so that the rice at the lower layer of the conveying belt 24 can be effectively cooled, and the cooling block 6 can also be used for cooling the rice at the upper layer of the conveying belt 24, so that the situations of heating and the like caused by the fact that the lower layer of the rice is not effectively cooled can be avoided; according to the rice cooling device, the pushing mechanism 8 can be used for flattening the rice on the conveying belt 24, so that the rice can be prevented from being accumulated on the conveying belt 24, the phenomenon that the rice in the accumulation part cannot be effectively cooled due to the accumulation of the rice on the conveying belt 24 can be avoided, the efficiency of the cooling block 6 for cooling the rice is improved, the heating quality change of the rice due to effective cooling is avoided, and the waste of grains is avoided.

The rice milling processing method adopting the spreading cooling device specifically comprises the following steps:

s1, equipment docking and checking: butting the guide cylinder 7 with a rice outlet of the existing rice mill, and carrying out routine inspection on the spreading and cooling device before operation;

s2, cooling and conveying: the rice can be conveyed in a blanking mode and cooled at the same time;

s3, stacking and flattening: the rice stacked on the conveying belt 24 after being discharged is flattened by the pushing mechanism 8.
