A grain management system includes a combine and a management server. The combine includes a grain measurer for outputting a measured value related to a component of harvested grains supplied to a grain tank, and a data transmitter for transmitting the measured value and field identification information for specifying the field to the management server via a communication line. The management server includes a receiver for receiving the field identification information and the measured value from the combine, a table manager for determining a measured value-grain component value table for deriving a grain component value using the measured value based on the field identification information, and a grain component value computer for obtaining the grain component value based on the measured value, using the measured value-grain component value table that is determined by the table manager.

In one aspect, a system for sensing harvested crop levels within an agricultural harvester may include a crop tank configured to receive harvested crop. The system may further include a sensor configured to emit a sensor beam into the crop tank for reflection off of the top surface of the harvested crop. Additionally, the system may include a reflection panel positioned at a minimum detectable crop level within the crop tank. The reflection panel may be configured to reflect the sensor beam when the current crop level is vertically below the minimum detectable crop level. A center of the reflection panel may be positioned closer to the sensor than an outer edge of the reflection panel such that the reflection panel diffuses the sensor beam as it reflects off of the reflection panel.

A combine including a frame, power unit and a crop gathering and processing device. A grain tank is mounted on the frame. An elongated closed end tube is vertically oriented within the grain tank and has a plurality of uniformly spaced openings along its length. A pneumatic pump pressurizes the interior of the tube. A pressure sensor senses the interior pressure of the elongated tube, so that grain building up therein selectively covers the plurality of openings to cause a proportionate increase in air pressure.

One or more techniques and/or systems are disclosed for automating the collection of product harvested from a site, such as grain from a field, and filling truck trailer for transport off site. These techniques can help operations that want to improve efficiency, while reducing field compaction and other issues related to weather or environmental conditions. A predetermined level of product can be identified for the target truck trailer, and an optimized fill method can be determined for filling the truck trailer efficiently using one or more mobile transport containers moving product from the field. A sensor array can detect an amount of the product disposed in the mobile transport container during transfer, and used to fill the mobile transport container to a predetermined level based at least on the optimized fill method. The mobile transport container is then used to fill the target truck-trailer container to its predetermined level.

A combine that can accurately measure the weight of grain retained in a grain tank is provided. When a weight measurement signal is output from a measurement switch 66, a weight measurement decision unit 75 instructs a working state determination unit 71 to perform working state determination. If it is determined that the combine is in the working state, the weight measurement decision unit 75 does not instruct a load cell 39 to perform weight measurement.

A grain harvesting articulated combine includes a forward crop processing power unit (PPU), a rear grain cart, and an articulation joint that connects the PPU with the rear grain cart. The articulation joint includes a grain auger assembly running from the PPU to the rear grain cart for transferring clean grain from the PPU to the rear grain cart and has a forward end at the PPU and a rear end adjacent to the rear grain cart. The grain auger assembly is housed within a tube with a rotating auger housed therein. A grain yield sensor is carried by the rear grain cart and is located adjacent and to and beside the grain auger assembly wherein the auger housed therewithin throws grain against the grain yield sensor. The auger is terminated by a rotating paddle assembly that throws the grain against the grain yield sensor.

An improved self-propelled grain harvester and threshing machine characterized by the sieves, cleaning fan and grain tank being beneath the grain harvester's threshing system which puts the center of gravity in the bottom of the machine and eliminates the need for conveying the grain throughout the machine for cleaning and to the top of the machine for storage. This configuration eliminates several clean grain conveying systems and reduces the length of the reprocess tailings elevator giving the machine a safe low profile and center of gravity when the machine is empty and the center of gravity lowers as the grain tank fills.

A combine for reaping culms in a field while traveling, and accumulating, in a grain tank 2, grains obtained by threshing reaped culms, includes: a yield calculator for calculating a yield per unit of travel, which is a yield per unit of travel distance; a work travel determiner 53 for determining non-harvest work travel that does not involve grain harvesting, and harvest work travel that involves grain harvesting; a harvest map data generator 66 for generating harvest map data in which the yield per unit of travel, a travel route on which the combine has traveled in a field, and a result of determination performed by the work travel determiner are associated with one another; and a harvest information recorder for recording the harvest map data.

A compression thrower for a sugarcane harvester having a receptacle for receiving sugarcane. The compression thrower includes a first belt configured to receive sugarcane from the receptacle. A compression device is configured to compress sugarcane into a mat of sugarcane against a second belt adjacent the compression device. The second belt is configured to propel the mat of sugarcane from the sugarcane harvester to a target location.

A seed level managing system includes a seed tank configured to contain seeds, a plurality of seed level sensors placed on a sidewall of the seed tank, a surface detecting sensor, and a controller. The controller includes one or more processors, one or more memory modules, and machine readable instructions stored in the one or more memory modules that, when executed by the one or more processors, cause the controller to receive first information from the plurality of seed level sensors; receive second information from the surface detecting sensor and determine a number of the seeds in the seed tank based on the first information and the second information.
