Detailed Description
As shown in fig. 1-4, a commutator unit for a dryer is a straight quadrangular prism with a hollow middle part and two through ends, and comprises a front side plate 13, a left side plate 10, a rear side plate 11 and a right side plate 12 which are fixed together, wherein the hollow part is divided into two independent grain changing channels by a partition plate: a first grain changing channel 51 and a second grain changing channel 52.
The first grain changing channel 51 and the second grain changing channel 52 are both divided into an upper part and a lower part through a horizontal space plane, and the horizontal space plane (plane HDCEP) is an equal division plane of a straight quadrangular prism.
For convenience of expression, the letters in the drawings are explained as follows: the middle point of the upper end of the rear side plate 11 is point A, the middle point of the upper end of the front side plate 13 is point B, the intersection point of the upper ends of the front side plate 13 and the left side plate 10 is point G, the intersection point of the upper ends of the rear side plate 11 and the right side plate 12 is point X, the center of the left side plate 10 is point D, the center of the right side plate 12 is point E, the center of the straight quadrangular prism is point C, the middle point of the intersection line of the left side plate 10 and the rear side plate 11 is point H, the middle point of the intersection line of the front side plate 13 and the right side plate 12 is point P, the center of the lower end surface of the straight quadrangular prism is point F, the middle point of the lower end of the front side plate 13 is point N, and.
The upper part of the first grain changing channel 51 is separated from the upper part of the second grain changing channel 52 by a left upper partition plate 31, an upper partition plate 20 and a right upper partition plate 41, wherein the left upper partition plate 31 is rectangular GBCD, the upper partition plate 20 is triangular ABC, and the right upper partition plate 41 is rectangular ACEX.
The lower part of the first changing channel 51 is separated from the lower part of the second changing channel 52 by a left lower dividing plate 32, a lower dividing plate 21 and a right lower dividing plate 42, wherein the left lower dividing plate 32 is rectangular HDFM, the lower dividing plate 21 is triangular DEF, and the right lower dividing plate 42 is rectangular PEFN.
All the contact positions among the side panels, the separation plates and the side panels and the separation plates are fixedly connected.
The side panels and the partition plates are all made of metal, and all the fixed connections among the side panels, among the partition plates and among the side panels and the partition plates are welded.
The working principle is as follows:
when the grain changing machine is used, grains from the upstream respectively enter the upper parts of the first grain changing channel 51 and the second grain changing channel 52, referring to fig. 4, the grains entering the upper part of the first grain changing channel 51 are positioned on the left side, and the grains entering the upper part of the second grain changing channel 52 are positioned on the right side.
Referring to fig. 5, as the grains fall, the sectional area of the upper portion of the first food exchange passage 51 on the left side of the whole diverter is gradually reduced, and the reduction is performed from the front to the rear, while the sectional area of the upper portion of the first food exchange passage 51 on the right side of the whole diverter is gradually increased, and the increase is performed from the rear to the front. Similarly, the cross-sectional area of the upper portion of the second refill passage 52 on the right side of the overall diverter decreases progressively and this decrease is from the rear to the front, while the cross-sectional area of the upper portion of the second refill passage 52 on the left side of the overall diverter increases progressively and this increase is from the rear to the front.
Referring to fig. 6, when the grains fall to the junction of the upper and lower parts, the first grain changing channel 51 is entirely behind, and the second grain changing channel 52 is entirely in front.
Referring to fig. 7, as the grains continue to fall, the sectional area of the lower portion of the first grain change passage 51 on the left side of the entire diverter is gradually reduced, and the reduction is performed from left to right, while the sectional area of the lower portion of the first grain change passage 51 on the right side of the entire diverter is gradually increased, and the increase is performed from right to left. Similarly, the cross-sectional area of the lower portion of the second transfer passage 52 decreases progressively from right to left across the diverter, while the cross-sectional area of the lower portion of the second transfer passage 52 increases progressively from left to right across the diverter.
Referring to fig. 8, when the grains fall to the lower end surface, the first grain changing channel 51 is on the right side, and the second grain changing channel 52 is on the left side, so that the direction change is realized.
In the whole process, the cross-sectional areas of the two grain changing channels are constant.
