②各部风量的调整 根据比重分离台面混合谷物的分离情况调整风扇泄风量调节

②Adjust the air volume of each part according to the separation of the mixed grains on the specific gravity separation table. Adjust the fan air discharge volume adjustment board (see Figure 2) and the fan air direction adjustment board (see Figure 2). The air volume of the fan should be adjusted based on the front half of the specific gravity separation platform. It can be seen that the mixed grain moves smoothly on the table, the impurities separate from the grain quickly and return quickly, and the output speed of the clean grain is fast, which is regarded as the best state. If the mixed grain is on the table, the movement is not stable, the separation of impurities and the backflow are not obvious, and the output speed of the net grain is slow. This indicates that the front air volume is large. The fan wind direction adjustment plate should be adjusted to make the excess air flow to the back of the specific gravity separation table, such as Although the movement of the mixture on the surface of the specific gravity separation table is stable, the separation of impurities is poor and the grain output speed is fast, which indicates that the front air volume is small. The fan wind direction adjustment plate should be adjusted to increase the air volume in front of the specific gravity separation table;

(2) The adjustment of the air volume of each department adjusts the fan air leakage adjustment board (see Figure II) and the fan wind direction adjustment board (see Figure 2) according to the separation of the proportion separation table mixed grain, and the fan air leakage volume should be adjusted according to the proportion separation table in front of the half, depending on the smooth movement of the mixed grain on the table, the impurities are separated from the grain quickly and reflux fast, and the clean grain output speed is fast, as the best state. Such as mixed grain in the table movement is not smooth, impurities separation and reflux is not obvious, the net grain output speed is slow, which indicates that the front air volume is larger, should adjust the fan wind direction adjustment plate, so that the excess air flow to the proportion of separation table surface rear, such as the proportion separation table mixed material although smooth movement, but poor impurities separation, grain output speed, which indicates that the front air volume is small, should adjust the fan wind direction adjustment board, so that the proportion of the separation table front wind volume increased;

② Air volume adjustment of each part According to the separation situation of the mixed grain on the specific gravity separation table, adjust the fan exhaust volume adjusting plate (see Figure 2) and the fan wind direction adjusting plate (see Figure 2). The fan exhaust volume should be adjusted according to the front half of the specific gravity separation table. It is considered that the mixed grain moves smoothly on the table, the impurities separate from the grain quickly and return quickly, and the clean grain output speed is fast, which is regarded as the best state. For example, the movement of mixed grain on the table is not stable, the impurity separation and reflux are not obvious, and the net grain output speed is slow, which indicates that the front air volume is large. The fan wind direction adjusting plate should be adjusted to make the excess air flow to the rear of the gravity separation table. For example, although the mixture on the gravity separation table moves smoothly, the impurity separation is poor, and the grain output speed is fast, which indicates that the front air volume is small, so it should be adjusted Adjust the fan wind direction adjusting plate to increase the air volume in front of the specific gravity separation table;<br>
