Sheep foot roller

Sheep foot roller

The sheep foot roller is generally towed, pulled by a crawler tractor, and several sheep foot rollers can be combined in series to be pulled by a high-power tractor to improve production capacity. The sheep's foot roller is composed of a roller wheel and a rectangular frame. The roller is a closed cylinder made of steel plate rolled and welded. Sand, iron sand or water can be loaded into the wheel through the sand loading port on the side to increase the roller weight. The shape and size of the protruding sheep foot have great influence on the compaction effect and compaction quality. There are many shapes of sheep's feet, which are selected mainly according to the maximum density of the rolling cushion material and the minimum influence on the surface layer.

Description

Working principle:

The sheep's foot mill is a static compacting machine with a uniform distribution and staggered arrangement of Angle protruding material welded on the surface of the roller. The horn roller is a kind of non-smooth roller, the horn shaped protruding object is higher than the convex roller, but its end area is smaller than the convex roller. The convex block has the shape of sheep foot, cylinder and square column, etc. The frame before and after the steel wheel is equipped with a comb scraper to remove the mud stuck between the convex block. sheep's foot mill is mainly used for soil embankment and subgrade compaction engineering.

 

Work efficiency:
The unit pressure of the sheep's foot mill is large, so that the packing is uniform, and the compaction effect is high. Due to the small area of the sheep's feet, the unit pressure is large, and when the sheep's feet are inserted into the soil layer, they will also have a lateral extrusion effect on the surrounding soil. The compaction process is from bottom to top, and the compaction is uniform and effective. Due to the formation of a large number of sheep foot pits on the soil surface, it is conducive to the combination of upper and lower soil layers, eliminating the planing process, and increasing the integrity and impermeability of the fill. It is worth noting that the sheep's foot mill is not suitable for compacting sandy soil, because when the sheep's foot is pulled out from behind the road, the newly compacted sand will loosen, so that the actual compaction effect cannot be obtained.
