[0023] The technical solutions in the embodiments of the present utility model will be apparently and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-6 As shown in the figure, a kind of fertilizer impurity screening device, shell 1, the top of shell 1 is fixed with feed pipe 101, one side of shell 1 is provided with discharge port 102, the surface of shell 1 is slidably connected with collection box 103, the inner cavity of shell 1 is fixed with filter plate 104, filter plate 104 side is rotatably connected with threaded rod 2, threaded rod 2 surface is threadedly connected with movable plate 201, the top of movable plate 201 is provided with multiple through holes 202, the top of movable plate 201 outside through hole 202 is provided with multiple mounting holes 203, the inner cavity of mounting hole 203 is fixed with mounting plate 204, the both ends of mounting plate 204 are fixed with spring 205, one end of spring 205 is fixed with top block 206.

[0025] When it is necessary to adjust the filter hole size on the filter plate 104, first, the handle is connected with the connecting head 6 through the reserved groove 601, and after ensuring firm connection, the handle is rotated, at this time, the rotation of the handle drives the threaded rod 2 to rotate, and along with the rotation of the threaded rod 2, the movable plate 201 connected with the threaded rod 2 is also subjected to the traction force, since the through hole 202 is arranged at the top of the movable plate 201, the through hole 202 will also move to the left along with the movable plate 201, and in the process of moving to the left, the relative position between the through hole 202 and the filter hole on the filter plate 104 changes, the through hole 202 intersects with the filter hole on the filter plate 104, and the overlapping part gradually decreases, since the overlapping part of the through hole 202 and the filter hole decreases, the actual flow area of the filter hole also decreases, so that the size of the filter hole is effectively adjusted, and the requirement of adjusting the filter hole size on the filter plate 104 is met, since the filter hole of the filter plate 104 is adjusted to be small, the screening precision of fertilizer particles can be improved, and finer impurities can be effectively removed, so that the quality and purity of the fertilizer are improved.

[0026] When it is necessary to restore the filter hole size of the filter plate 104 to the original size, the threaded rod 2 is counterclockwise rotated, the threaded rod 2 drives the movable plate 201 and the through hole 202 to move to the right, until the through hole 202 is completely aligned with the filter hole on the filter plate 104, and once the through hole 202 is aligned with the filter hole on the filter plate 104, the rotation of the threaded rod 2 is stopped, at this time, the size of the filter hole should have been restored to the original size, and finally, whether the size of the filter hole meets the requirement is checked, if further fine adjustment is needed, the above steps can be repeated until a satisfactory effect is achieved.

[0027] When it is necessary to clean the filter hole of the filter plate 104, the threaded rod 2 is counterclockwise rotated, the threaded rod 2 drives the movable plate 201 and the top block 206 to move to the right, until the top block 206 is completely aligned with the filter hole on the filter plate 104, at this time, the top block 206 is popped out under the action of the spring 205, and the impurities in the inner cavity of the filter hole of the filter plate 104 are pushed out, so that the filter hole of the filter plate 104 is cleaned, after cleaning, the threaded rod 2 is clockwise rotated, so that the movable plate 201 and the top block 206 move to the left, since the top block 206 is in the shape of a hemisphere, when the top block 206 is extruded by the filter hole of the filter plate 104, the top block 206 will automatically shrink until the top block 206 hides in the inner cavity of the mounting hole 203 and the through hole 202 is completely aligned with the filter hole on the filter plate 104.
