because one end of each of the two driving guide rails 12 is in threaded fit with the transmission shaft 10, and the other end of each of the two driving guide rails 12 is located in the mounting groove 33 formed in the swinging plate 14, when the transmission shaft 10 rotates relative to the swinging plate 14, as shown in a in fig. 29, the two driving guide rails 12 move along the axis of the transmission shaft 10 under the action of the threads; the two driving rails 12 move along the axis of the transmission shaft 10 to respectively drive the two transmission rods 35 mounted thereon to move along the axis of the transmission shaft 10, and the two transmission rods 35 move to drive the two trigger rods 13 to move, as shown in b in fig. 29, so that the two trigger rods 13 leave the middle part and the articles pass through, and since the support plate 28 in the trigger screening plate 5 is not in contact with the support groove 7 on the screening pipe 2 in this case, the trigger screening plate 5 swings downwards under the gravity of the articles to filter the articles into the second collecting box 3, as shown in b in fig. 25; as shown in a in fig. 26, a in fig. 27, a in fig. 28, if the size of the article is such that the article first contacts with the two triggering rods 13 in the triggering and screening plate 5, the article pushes the two triggering rods 13 to move on the swinging plate 14, the two triggering rods 13 move to drive the two transmission rods 35 to move, the two transmission rods 35 move to drive the two guide rods 29 to move, the two guide rods 29 move to drive the supporting plate 28 to move, so that the front end of the supporting plate 28 moves out of the swinging plate 14, when the article contacts with the swinging plate 14 during rolling, the article pushes the swinging plate 14 to swing, as shown in b in fig. 29, the swinging plate 14 swings so that the two triggering rods 13 give way from the middle part, the article passes through, if the distance that the front end of the supporting plate 28 moves out is not enough to make the front end of the supporting plate 28 contact with the supporting groove 7 in the screening pipe 2, i.e. the diameter of the article is still smaller than that, as shown in fig. 26 b, the trigger sifting plate 5 swings downward by the gravity of the articles to filter the articles into the second collecting box 3; if the support plate 28 is moved out by a distance sufficient to make the front end of the support plate 28 contact the support groove 7 in the screening duct 2 and the front end of the support plate 28 is not matched with the escape groove 8 formed in the screening duct 2, i.e., the diameter of the article is within the range of the diameter of the standard article, as shown in c of fig. 27, the support plate 28 is supported by the support groove 7 in the screening duct 2 and the article is filtered into the first collecting box 1 along the screening duct 2 by gravity, as shown in b of fig. 27; if the support plate 28 is moved out a distance sufficient to allow the front end of the support plate 28 to engage with the escape slot 8 formed in the screening conduit 2, as shown in c of fig. 28, i.e. the diameter of the article is larger than that of the standard article, the triggered screening plate 5 will swing downward under the gravity of the article, as shown in b of fig. 28, to filter the article into the second collecting box 3; after the objects are screened by the trigger screening plate 5, the swing plate in the trigger screening plate 5 swings upwards under the action of the volute spiral spring 44, the swing plate 14 swings upwards to drive the two gear rings 9 to rotate, the two gear rings 9 rotate to enable the transmission shaft 10 to rotate, the transmission shaft 10 rotates to drive the two driving guide rails 12 to move along the axis of the transmission shaft 10, the two driving guide rails 12 move along the axis of the transmission shaft 10 to respectively drive the two transmission rods 35 arranged on the driving guide rails to move along the axis of the transmission shaft 10, and the two transmission rods 35 move to drive the two trigger rods 13 to move, so that the two trigger rods 13 reset; at the same time, the transmission shaft 10 rotates to rotate the winding wheel 22, the pull rope 16 is released, and the two driving blocks 17 are reset under the action of the two second springs 15.
In summary, the following steps:
according to the screening device, the screening trigger screening plate 5 in the screening device is modularized, and a traditional door structure and a swinging plate 14 are combined into a whole, so that the screening device which is divided into an upper side and a lower side compared with the door structure and the swinging plate 14 in the installation of the screening trigger screening plate 5 is convenient to install; according to the screening device designed by the invention, the upper part of the screening pipeline 2 is not required to be damaged, and the trigger screening plate 5 is directly arranged on the two shaft holes 11 formed in the screening pipeline 2, so that the installation cost is reduced; according to the screening device, the triggering and screening of the device are both positioned at the lower side of the screening pipeline 2, the space required for installing the triggering screening plate 5 is small, and the utilization rate of the screening pipeline 2 is high; according to the screening device designed by the invention, the front ends of the supporting plates 28 and the supporting grooves 7 in the screening pipeline 2 are designed, so that the size of the screened objects is within a certain range, and the screened objects can be screened if the size is too large or too small.
