As shown in Figure 3 and Figure 4, the air selection channel 3 is separated into two independent air selection channels by a partition 7-1 in the middle: the primary air selection channel 3-1 and the secondary air selection channel 3-2 , and are respectively provided with primary winnowing slide plate 17 and secondary winnowing slide plate 18 inside, the primary winnowing slide plate 17 and the secondary winnowing slide plate 18 are evenly punched with a diameter of 2-3.5mm holes, its The positive pressure fan 15 in the lower part blows the materials through the holes to separate the materials with different suspension speeds. There is a bar hole K for the material to slide down from the primary air selection slide 17 to the secondary air selection slide 18 at the position near the lower end of the primary air selection slide 17 in the channel partition 7-1. The inclination angle of the horizontal plane is 30-45 degree, and the inclination angle of the secondary winnowing slide plate 18 and the horizontal plane is 30-50 degree.

The primary air selection adjusting plate 19 and the secondary air selection adjusting plate 20 of the air volume of independent adjustment are respectively provided with the primary air selection sliding plate 17 and the secondary air selection sliding plate 18 below. The top of the sliding plate 18 is provided with a digital display anemometer 23 for the primary winnowing channel and a digital display anemometer 24 for the secondary winnowing channel. According to the suspension speed of the material, by adjusting the primary winnowing adjustment plate 19 and the secondary winnowing adjusting plate 20 respectively, the primary winnowing flap knob pull wire adjusting device 21 and the secondary winnowing turning flap knob pull wire adjusting device 22 can realize no Level adjustment to change the opening area of each winnowing channel, thereby changing the air volume and wind speed.

The working process of the utility model is: the mixture of walnut shell broken and graded, seed compartment and kernel is fed from one end of the feed hopper 2 above the primary winnowing channel 3-1 through the electromagnetic vibrating feeder 1 . The positive pressure blower 15 blows air below the passage to form a positive pressure airflow, and the airflow produced in the air selection passage 3 will remove the materials with lighter specific gravity ( Walnut shells and seed compartments and dust) are blown into the settling box 5. Concrete air selection is carried out in two stages. First, the mixture of walnut broken shells, seed compartments and kernels is passed through the channel partition 7- by the air selection slide plate 17 to the lower left after the first air selection under the action of gravity. The bar hole K on 1 slides into the secondary winnowing channel, and then falls into the beneficiation hopper 8 after being winnowed again at different wind speeds in the secondary winnowing channel. Wind speed adjustment in the winnowing channel: According to the suspension speed and ratio of the shells and seed compartments in the material, observe the digital display wind speed tester 24 of the corresponding channel, and adjust the primary winnowing adjustment below the winnowing channel by adjusting the primary knob and pull wire adjustment device 21 Plate 19, select the appropriate wind speed. When the material passes through the primary winnowing slide 17 of the primary winnowing channel and enters the secondary winnowing slide 18, due to the decrease in the proportion of shells in the material, the secondary adjusting knob and pull wire adjusting device 22 are used to adjust the lower part of the secondary winnowing channel. The secondary winnowing regulating plate 20 further carries out winnowing to the material, and rejects the shell remaining in the kernel. When the material enters the settling box 5, due to the sudden expansion of the area of the settling box, the wind speed decreases rapidly. In addition, the upper part of the settling box partition 7-3 is arc-shaped, so that the air flow turns quickly, and the walnut shell depends on its own gravity and airflow. Separated, falling into the corresponding part of the respective settling box 5, and discharged out of the body through the secondary winnowing rejection material discharge hopper 9 and the primary winnowing rejection material outlet 10, the walnut kernels are slid by the kernel discharge hopper 8 along with the effect of gravity. out of the body.
