Description

The surface of the drum 1 between the flaps 4. The tank 5 is set so that the upper permeable wall takes an inclined position. The drum 1 is rotated, which ensures that the soil penetrates the elevated end of the permeable wall 8. By changing the slope of the water permeable wall, the soil flow velocity along its plane is different, and the rotational speed of the drum 1 is evenly distributed and the soil flow is established. To examine the soil in a water-saturated state, the tank 5 is connected to the water circulation system with pre-filling it with water. The water coming from the circulation system to the nozzles 7, compartments (), the tank S goes through the permeable system 8 to the drum 1, weighing the soil under study. With a reverse flow of water from the drum through the soil, the compartments 6, the tank 5 and the nozzles 7 in the system, a load is created through the soil. Over the course of soil flow through the glass end wall of the drum. This measures the average flow rate and velocity distribution over the layer using a filmmaker. Hydrodynamic loads on the ground are determined by the pressure sensor system. The subject of the invention 1. A device for examining bulk materials, including a drum mounted on a support, blades and measuring devices, characterized in that, in order to make it possible to determine the kinematic characteristics of the moving bulk material, the drum is mounted on a support rotatably around a horizontal axis and provided with a container placed coaxially inside it, made with a segmental cross section and having an upper permeable wall, and the cavity of the container is divided and compartments, each of which is connected by a pipe with a water circulation system. 2. The device according to Clause 1, which is based on the fact that its support is made with support struts having rollers.
