A sensor system for counting elements of a flow of harvested material is disclosed. The sensor system comprises an oscillating circuit and a measuring device, wherein the oscillating circuit comprises at least one capacitive component with a capacitance and an inductive component with an inductance. The oscillating circuit has a resonance frequency which depends on the capacitance and the inductance. Further, the capacitive component is positioned in the region of the flow of harvested material, so that the capacitance is influenced by individual elements of the flow of harvested material. The measuring device is configured to determine the resonance frequency of the oscillating circuit. In this way, the sensor system is configured to deduce at least one property of the particular element of the flow of harvested material from the resonance frequency of the oscillating circuit.

A combine harvester is provided with a conveyance system for transporting crop material discharged by overhead grain separating apparatus to a grain cleaning shoe. The conveyance system comprises a series of oscillating pans which move the grain in a generally longitudinal direction. A return pan conveys the collected material forwardly to a front discharge edge from where the material falls onto a stratification pan below. The stratification pan conveys the collected material rearwardly to a rear discharge edge from where the material falls into the grain cleaning shoe. At least one of the return pan and the stratification pan is non-rectangular and has a non-transverse discharge edge.

The present invention refers to an automatic grain processing apparatus comprising, in an integrated manner, that is, in a single apparatus, the following units: a cleaning unit (2); a drying unit comprising a dryer (18), a grain weighing and classification unit; and a grain packaging and labelling unit. The present invention also refers to a grain integrity monitoring and tracking system, comprising one or a plurality of sensors arranged in a package and configured to measure the properties, such as temperature and/or moisture and/or pressure and/or vacuum of the packaged grains, together with the location of the load; and at least one communication module configured to receive the data from one or a plurality of sensors and configured to transmit and store the information from said one or a plurality of sensors in a cloud or any high-performance repository. Said sensors arranged in the package (34) can identify exactly how, when and where the load, that is, the packaged grains, is stored, the temperature, vacuum and pressure conditions of the grains, and also provide agile location responses for monitoring by the end client.

A hood assembly for a fan that has a base section, a discharge nozzle pivotally coupled to the base section, and a motor coupled between the base section and the discharge nozzle. Wherein, the discharge nozzle is repositionable with the motor to alter the orientation of the discharge nozzle relative to the base section.

A rotary cleaning system for a combine harvester that includes a hollow drum having a plurality of apertures along at least a portion of a length of an exterior surface of the drum, the drum having a feeding end configured to receive a harvested crop and a discharge end configured to expel chaff from the harvested crop and a guiding vane positioned in an interior of the drum, wherein one of the drum and the guiding vane is configured for rotation while the other one of the drum and the guiding vane is stationary to expel grain through the plurality of apertures in the drum. A feeding mechanism can be attached to supply the crop to the hollow drum. A fan can be attached to the rotary cleaning system to generate an air flow stream. A plurality of fingers can be positioned in the drum.

A handheld harvester apparatus may include a threshing assembly and a screening assembly within a housing. The threshing assembly may include a threshing drum with a plurality of blades coupled to a first axle. The plurality of blades may include a set of teeth configured to strip a plurality of seeds and plant material from a plant. The screening assembly may include a paddle assembly configured to receive the plurality of seeds and plant material from the threshing assembly, the paddle assembly including a plurality of paddles coupled to a second axle. The screening assembly may include a screen assembly positioned beneath the paddle assembly, the screen assembly including a plurality of pass-through apertures configured to define a threshold for the plurality of seeds. The screening assembly may include a collection chamber configured to receive any of the plurality of seeds that exit the plurality of pass-through apertures.

A combine and combine conversion for collecting agricultural plants in a manner that separates various parts of the plants for collection or disposal. A combine is provided with an improved system for collecting and cleaning seed of an agricultural material such as cannabis while collecting lightweight chaff, such as trichomes, and returning stalks back to the agricultural field. The system provides for rapid conversion of a combine to seed and chaff collection and back again.

A combine harvester includes a grain pan that is arranged to catch a crop stream. The grain pan is driven in a fore and aft oscillating manner to convey the crop stream rearwardly across a conveyance surface to a rear edge. The grain pan is provided with an upright panel extending in a fore and aft direction on the conveyance surface. A grain cleaning system is arranged to receive the crop stream from the grain pan. A crop stream analysis system is provided for analysing a vertical section of a crop material layer disposed on the grain pan. The analysis system includes a vertical array of photoelectric sensing devices mounted to the panel. Each photoelectric sensing device is configured to sense a reflectance of crop material disposed against the panel. A processor is configured to receive reflectance signals from the photoelectric sensing devices and determine a material stratification status from the reflectance signals.

A sugarcane harvester for harvesting sugarcane including a cutter configured to cut sugarcane into a sugarcane mat. An extractor is operatively connected to the cutter, and includes a fan housing having an inlet configured to receive the sugarcane mat and an outlet configured to discharge crop debris. A fan is located in the fan housing to move the sugarcane mat through the fan housing and includes a motor, blades rotatably coupled to the motor, and a blade angle of incidence mechanism operatively connected to the blades, wherein the blade angle of incidence mechanism adjusts the angle of incidence of the blades with respect to the motor. Sensors identify an air flow through the fan housing or a load placed on the motor during movement of the sugarcane mat through the fan housing. The angle of incidence of the blades is adjusted based on one or both of the air flow through the fan housing or the load placed on the motor.
