Los rodillos componentes (2, 3 y 4) que forman el conjunto de la criba en cada caso, se disponen acoplados a una transmisión común de accionamiento giratorio que es actuada por un moto-reductor (5), con lo cual resulta un conjunto sobre el que son susceptibles de transportarse los productos de aplicación conjuntamente con la suciedad recogida con los mismos en la recolección.The component rollers (2, 3 and 4) that form the whole screen in each case, are arranged coupled to a common rotary drive transmission that is operated by a moto-reducer (5), which results in a set on which products of application together with the dirt collected with them in The recollection.

Los rodillos (2, 3) de la primera parte se disponen con una separación entre ellos menor que el diámetro de los productos de aplicación, con lo cual durante el transporte por esa parte de la criba los productos son llevados hacia delante conjuntamente con las brozas y objetos extraños de mayor tamaño, cayendo por entre los rodillos (2, 3) la suciedad menor, como polvo, tierra, piedras pequeñas, etc.The rollers (2, 3) of the first part are they have a separation between them smaller than the diameter of the application products, which during transport by that part of the sieve the products are carried forward together with the larger brush and foreign objects, minor dirt falling between the rollers (2, 3), such as dust, earth, small stones, etc.

En relación con la función de transporte de los productos y objetos que deben ser llevados hacia delante, algunos rodillos (2) de esta parte de la criba se prevén con espiras helicoidales prominentes (6) en la periferia, las cuales favorecen el arrastre de desplazamiento de los productos y objetos, impidiendo que queden detenidos entre los rodillos (2, 3) componentes del transporte.In relation to the transport function of products and objects that must be carried forward, some rollers (2) of this part of the screen are provided with turns prominent helical (6) on the periphery, which favor the scrolling of products and objects, preventing them from being stopped between the rollers (2, 3) transport components.

A tal efecto, dicha parte de la criba puede formarse, según conveniencia de acuerdo con la aplicación, solo con rodillos (2) provistos de espiras (6), o con una combinación de rodillos (2) provistos de espiras (6) y rodillos (3) lisos, por ejemplo mediante una distribución alternada de unos y otros rodillos, sin que esto sea limitativo.To that end, said part of the screen may be formed, according to convenience according to the application, only with rollers (2) provided with turns (6), or with a combination of rollers (2) provided with turns (6) and smooth rollers (3), by example by an alternate distribution of each other rollers, without this being limiting.

La segunda parte del conjunto funcional de la criba se forma con rodillos (4) que poseen un diámetro central y sobresaliendo distribuidas en toda la longitud unas coronas (7) de mayor diámetro, disponiéndose estos rodillos (4) con sus coronas (7) enfrentadas, de modo que entre los tramos del diámetro central de los rodillos (4) consecutivos y las coronas (7) correspondientes, quedan unos huecos mayores que los productos de aplicación.The second part of the functional set of the sieve is formed with rollers (4) that have a central diameter and protruding crowns (7) of larger diameter, these rollers (4) being arranged with their crowns (7) facing each other, so that between the sections of the central diameter of consecutive rollers (4) and crowns (7) corresponding, there are some gaps larger than the products of application.

De este modo, cuando los productos y los objetos extraños de mayor tamaño que los acompañan llegan a esta zona de la criba, los productos caen por entre los rodillos (4), para recogerse por debajo sobre una cinta transportadora o en un contenedor, mientras que los objetos extraños son llevados hasta el final, en donde se descargan sobre un recogedor o transportador que los retira.In this way, when products and objects  larger strangers accompanying them arrive in this area of the sieve, the products fall between the rollers (4), to collected below on a conveyor belt or in a container, while foreign objects are carried to the final, where they are unloaded onto a pickup or conveyor that remove them.

Según la invención, tanto los tramos de diámetro interior de los rodillos (4), como la periferia de las coronas (7), van provistos con un estriado (8) en sentido longitudinal, de manera que dicho estriado (8) favorece el arrastre de los objetos extraños que deben ser llevados hasta el final del transporte.According to the invention, both the sections of diameter  inside the rollers (4), as the periphery of the crowns (7), are provided with a groove (8) longitudinally, of so that said striatum (8) favors the dragging of objects strangers that must be taken to the end of transport.

El estriado (8) de la periferia de las coronas (7) actúa además sobre los objetos extraños, orientando los objetos alargados, como tallos, ramas, etc., por entre las coronas (7) en el sentido del avance, lo cual evita que se produzcan atascos que puedan entorpecer el proceso.The striatum (8) of the periphery of the crowns (7) also acts on foreign objects, orienting elongated objects, such as stems, branches, etc., between the crowns (7) in the direction of progress, which prevents them from occurring traffic jams that can hinder the process.

En la realización práctica, el conjunto de la criba puede formar una unidad de funcionamiento y aplicación, yendo tanto los rodillos (2, 3) como los rodillos (4) incorporados en el montaje respecto de un mismos bastidor estructural (1); pero de igual modo, el conjunto de los rodillos (2, 3) separados a una distancia mayor que el diámetro de los productos de aplicación, y el conjunto de los rodillos (4) que determinan huecos intermedios mayores que los productos de aplicación, pueden formar unidades funcionales independientes, susceptibles de ser utilizadas conjuntamente o por separado.In the practical embodiment, the whole of the sieve can form an operation and application unit, going both the rollers (2, 3) and the rollers (4) incorporated in the assembly with respect to the same structural frame (1); but of similarly, the set of rollers (2, 3) separated to a distance greater than the diameter of the application products, and the set of rollers (4) that determine intermediate gaps larger than application products, they can form units independent functional, likely to be used jointly or separately.
