Abstract: Disclosed are systems and apparatuses for processing agricultural and other grains. The systems and apparatuses include integrated units for cleaning, drying, weighing, classifying, packaging, labelling, tracking, and load monitoring of grains. In some embodiments, the systems and apparatuses include a cleaning unit for depositing and sifting grains, a drying unit for moving grains through a hot environment, a grain weighing and classification unit, and a packaging and labelling unit for vacuum sealing and labelling grains, all in one integrated unit.

Abstract: A riding vehicle may include a blower assembly, a mower deck, and a power source. The blower assembly may be configured to direct air from an air inlet to at least one air outlet to move surface debris. The mower deck may be configured to cut a lawn formed of grass or other vegetation. The blower assembly may be configured to direct air to an interior space of the mower deck for assisted discharge of cuttings.

Abstract: An automatic working system includes a self-moving device moving and working inside a defined working area and an energy module supplying power to the self-moving device. The self-moving device includes a body, a movement module, a task execution module, and a control module. The energy module is selectively configured to supply power to the self-moving device or another electric tool different from the self-moving device. The self-moving device includes an accommodating cavity provided with an inlet and configured to accommodate the energy module and a protective cover configured to operably block the inlet. The self-moving device further includes a drainage system configured to drain water to prevent water from entering the accommodating cavity.

Abstract: A field incinerator has a carriage with a frame. A fuel tank such as a propane tank is mounted to the frame. An outlet passage extends from the tank. An outlet valve is mounted to the outlet passage. The outlet valve controls the outlet passage. The first gauge has a first gauge tap. The first gauge tap is connected to the fuel tank or the outlet passage. The first gauge has a first gauge control parameter. The first gauge control parameter requires less than a first set pressure for activation. The second gauge is connected to the outlet passage downstream from the first gauge. The second gauge has a second gauge control parameter. The second gauge control parameter requires more than a set second pressure for activation. The first gauge control parameter and the second gauge control parameter must both be fulfilled for opening the outlet valve.

Abstract: A drying apparatus includes a body, a controller, a thermal sensor to sense an ambient temperature, a humidity sensor to sense an ambient humidity, an air outlet to vent an airflow, a flow generator to generate the airflow within the body, and a thermoelectric device including an inward surface and an outward surface, where the inward surface heats or cools the airflow generated by the flow generator. The controller is configured to control a temperature of the inward surface of the thermoelectric device based on the ambient temperature and the ambient humidity.

Abstract: A grass cutting mobile robot includes a body and a blade assembly connected to the body and rotatable about a drive axis. The blade assembly includes blades, a housing to hold the blades, and a spring that connects the blade to the housing. The housing includes a slot in which to mount a blade so that a portion of the blade is movable through the slot towards another blade in response to an impact. The slot slopes upwards in the housing towards the body, thereby enabling the blade to move upwards relative to a ground surface toward the body in response to the impact. The spring is for constraining movement of the blade relative to the housing.

Abstract: A seed cotton dryer comprises an array of electromagnetic wave energy generators in a cotton gin, a cotton picker/stripper. An appropriate amount of energy is used to evaporate a considerable amount of moisture in the seed cotton without producing enough energy to pop the cotton seeds. Seed cotton dried by wave energy is much easier to separate the cotton seeds and lint from leaves, stems and other plant parts. The seed cotton is preferably transported through the dryer in a conduit having flat sides which reflects the wave energy more efficiently than through a round conduit. Provisions are made to prevent arcing in the transport conduit when extraneous metal pieces are inadvertently mixed with the seed cotton. In some embodiments, heated air from a diesel engine is used to dry crops as they are being harvested.

Abstract: An exhaust conditioning system for use with a tractor towing an air seeding implement comprises an exhaust duct arranged to communicate exhaust emissions from the engine of the tractor to the seed fan of the air seeding implement. A condenser receives the exhaust emissions of the exhaust duct therethrough between the engine and the seed fan. A condenser fan cools a surface of the condenser. A computer controller controllably varies a rate of at least one of the condenser fan, the seed fan or revolutions per minute of the engine responsive to a sensed temperature of the exhaust emissions to maintain the temperature of the exhaust emissions within a selected temperature range and such that the exhaust emissions are arranged to influence germination of the seeds either by humidity, oxidised organic matter or bio-char.

Abstract: An exhaust circulation lawnmower is disclosed in which grass clippings are sent, along with carrier air, from a cutter housing to a grass bag; the grass clippings are held in the grass bag; and the carrier air is returned to the cutter housing as exhaust. A surface area A1 of a grass clippings discharge opening and a surface area A2 of a recirculation opening have a relationship of A2?{1/(1??N)0.5}A1, where A1 is the surface area of the grass clippings discharge opening through which the grass clippings and carrier air are discharged from the cutter housing to the grass bag, A2 is the surface area of the recirculation opening through which the carrier air is recirculated from the grass bag to the cutter housing, N is the number of bends having an angle of ? degrees in the space between the grass clippings discharge opening and the recirculation opening, and ? is a pressure loss coefficient for each of the bends.

Abstract: An attachment to replace existing landscaping trimmer heads and for mounting on new trimmers. The attachment includes specific structure for trimming grasses and weeds as well as structure for the removal of weeds unwanted grasses and unwanted shallow roots. The structure includes at least one pre-cut flexible trimming line that extends through the body member and a tapered bit member attached to the body member. The trimming line cuts and trims grasses and weeds and the tapered bit member has structure attached thereto for removal of weeds, unwanted grasses and unwanted shallow roots.
