A soil breaking roller with a screening structure

Abstract

The utility model discloses a kind of soil crushing roller with screening structure belong to agricultural machinery technical field, it includes screening cylinder, inside rotatingly connected with inner cylinder in screening cylinder, and the inner cylinder inner wall is fixedly connected with multiple groups of convex ring, first discharge gate is established in the lower right side of screening cylinder, second discharge gate is established in the bottom of screening cylinder, and the convex grain on the outer side of soil roller and convex ring are all spiral;The utility model is through the reverse rotation of inner cylinder and soil roller and crushes soil, synchronously utilizes screen hole to realize soil particle classification, without the transfer link of traditional soil crushing and screening equipment, reduce equipment land occupation and energy consumption, make the soil after soil crushing directly complete screening especially suitable for large-scale farmland cultivation scene, utilize soil roller power and drive cam rotation through transmission belt, dynamically break screen hole blockage, avoid the decline of screening efficiency due to soil adhesion, without additional power source, knock frequency is automatically adjusted with soil crushing load, ensure that equipment continuous stable operation, reduce artificial shutdown cleaning cost.
