A method for determining a density of a harvested material includes transmitting radar signals into the harvested material from a transmitting unit, receiving the radar signals reflected by the harvested material by a receiving unit, determining a permittivity of the harvested material as a function of the reflected radar signals via an evaluation unit, and determining the density of the harvested material as a function of the determined permittivity via a signal processing unit.

An intermediate sump warning system having a sensor associated with a gate of an intermediate sump. The sensor is connected to a controller that activates a warning signal when the sensor detects that the gate is in an open position.

This invention relates to a stand for supporting hay bales above the ground. The inventive hay stand The device is formed in the shape of an rectangular prism or cuboid from an inert plastic, closed-cell, polyurethane structural foam that will not allow water or air to move through it. The devices are constructed by pouring the structural foam material into forms that are constructed to yield the desired shape. The structural foam has two chemicals that are mixed and then poured into the form. The foam then heats and rises to take on the shape of the interior of the form. Once the foam is fully cured, the forms are removed, and the device is ready for use. Hay stands constructed in accordance with the present invention are useful for protecting hay bales from spoilage due to ground moisture.

Air handling system for a climate control system in a housing that includes at least a delimited space with controlled environment, CE space. The air handling system includes an air handling unit, AHU, a pipe system and a perforated plate assembly. The pipe system includes a branched tree-like structure of conduits, that branches in the direction from the air handling unit towards the perforated plate assembly for homogenous distribution of air over the perforated plate assembly such that the air flow through the perforated plate assembly into the CE space is an air flow under laminar flow conditions. Also, a climate system for climate control in such a delimited space, a modular unit including such a delimited space and such a climate system, and an assembly of modular units.

A grain management system includes a robot and a computer system located remotely from one another and configured to wirelessly communicate. The robot comprises an auger-based drive system, a memory, and a processor which controls movement of the robot, via the drive system, relative to grain in a bulk store. During a load-in the robot traverses a landing zone portion, where the grain lands during load-in, of a surface of a pile of the grain to disperse broken grain and foreign material away from the landing zone portion. The dispersal is effected in part by rotation of augers of the drive system. The robot additionally traverses a sloped portion of the pile of grain to incite sediment gravity flow by rotation of the augers. The sediment gravity flow reduces a slope of the sloped portion and further disperses the broken grain and foreign material away from the landing zone portion.

A robot comprises an auger-based drive system, a memory, and a processor coupled with the memory and configured to control movement of the robot, via the auger-based drive system, relative to grain in a grain bin. The processor is further configured to direct performance of a maintenance traversal, by the robot, of a surface of a pile of the grain during a storage period of the grain. The maintenance traversal disperses a layer of the grain on and near the surface and thus hinders crust formation on the surface during the storage period. The dispersal is effected by rotation of augers of the auger-based drive system during the maintenance traversal.

A robot comprises an auger-based drive system, a memory, and a processor coupled with the memory and configured to control movement of the robot, via the auger-based drive system, relative to grain in a flat storage bulk store. The processor is further configured to direct traversal, by the robot, of a portion of a pile of the grain in the flat storage bulk store. The traversal is performed to incite sediment gravity flow in the portion of pile of grain system to walk-down the grain in the portion. The sediment gravity flow is incited by disruption of viscosity of the portion of the pile of grain through agitation of the portion of the pile of grain by auger rotation of the auger-based drive.

An apparatus for controlling fermentation of natural material. The apparatus includes one or more sensors configured to measure at least one property of natural material, a container configured to contain a chemical reactive agent reducing or limiting a fermentation process of the natural material; a valve coupled with the container; and a controller configured to process the measured at least one property of the natural material, and, if the processing meets a predetermined condition, control the valve to open so that the chemical reactive agent is released into the natural material in order to limit the fermentation process of the natural material.
