Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution:

a rotary screen for producing water-soluble fertilizer comprises an installation frame 1, a rotary screen body 2 arranged in the middle of the upper end of the installation frame 1 and a protection plate 3 arranged in the middle of the installation frame 1, wherein the protection plate 3 is positioned below the rotary screen body 2, and one side of the upper end of the installation frame 1 is provided with a cleaning assembly 4 for cleaning the rotary screen body 2;

cleaning assembly 4 includes that the symmetry locates two backup pads 401 of mounting bracket 1 upper end and locates the installation shell 402 between two backup pads 401, one of them backup pad 401 inboard is equipped with mounting panel 403, mounting panel 403 upper end is equipped with air pump 404, the air pump 404 output is linked together through connecting pipe and installation shell 402 are inside, installation shell 402 is close to 2 one side equipartitions of drum sieve body and is equipped with a plurality of brushes 406, installation shell 402 is close to 2 one side of drum sieve body and down the lateral wall all is equipped with a plurality of jet heads 405, a plurality of jet heads 405 are linked together with installation shell 402 is inside.

Further, the plurality of brushes 406 are all in contact with the outer surface of the trommel body 2, and the plurality of brushes 406 and the gas nozzles 405 are arranged in a staggered manner, so that the brushes 406 can shake by the gas blown by the gas nozzles 405.

Further, the cross section of installation shell 402 can be better for the arc make brush 406 and trommel body 2 contact each other, the lower extreme of installation shell 402 is less than the upper end of guard plate 3 and is located inside the guard plate 3 and prevents that fertilizer from throwing away from the guard plate 3 upper end of being less than.
