A conveyance system includes a conveyance device including a first conveyance mechanism configured to convey freight supplied from a loader, and a second conveyance mechanism configured to convey the freight supplied from the first conveyance mechanism, a weight detection device configured to detect weight of the freight loaded on the second conveyance mechanism, and a control apparatus. The control apparatus includes a first conveyance control unit configured to control the first conveyance mechanism. The first conveyance control unit controls the first conveyance mechanism based on a detection value of the weight detection device.

In one aspect, an agricultural harvester may include a harvesting implement having a belt support assembly configured to support a conveyor belt of the harvesting implement as the conveyor belt moves relative to the belt support assembly. The system may also include a sensor provided in operative association the belt support assembly, with the sensor being configured to detect a parameter indicative of a force exerted on the belt support assembly as the conveyor belt moves relative to the belt support assembly. Furthermore, the system may include a controller communicatively coupled to the sensor, with the controller being configured to monitor the amount of the plant materials entering the harvester based on measurement signals received from the sensor.

The disclosure relates to a feeder apparatus, system and method applied to the movement of bulk material and in particular for the movement of bulk run of mine material from a working site. In particular, a feeder (5) is disclosed comprising: a feed device having a material receiving end for receiving material; a material discharge end (11) distal of the material receiving end; an endless conveyor disposed to define a conveying surface (9) between the material receiving end and the discharge end (11) movable in use to cause material received at the material receiving end to be conveyed to the material discharge end (11), wherein the endless conveyor comprises a plurality of successively arrayed metal plates, pans or flights; a material flow monitoring device disposed in association with the feed device and adapted to obtain in use a measurement representative of a quantity of material passing along the conveying surface (9) of the endless conveyor; wherein the feed device is conformed as a surge conveyor; the feeder further comprises

A conveyor capacity control system includes a conveyor operative to receive granular material at a conveyor intake thereof and convey same to a conveyor discharge with a conveying device at a conveyor flow rate up to a maximum conveyor flow rate, and a granular material container with a container discharge opening oriented to discharge granular material from the granular material container into the conveyor intake, and a discharge gate movable to control a size of the container discharge opening. A flow rate control processor is operative to determine the maximum conveyor flow rate and detect when a discharge flow rate of granular material from the container discharge opening into the conveyor intake is greater than or less than the maximum conveyor flow rate, and increase or decrease the discharge flow rate to substantially coincide with the maximum conveyor flow rate. A hoist control is also provided for a truck box.

A discharge flow rate of a loss-in-weight scale is controlled by continuously changing control outputs to save the time necessary for data stabilization. A curve relating the discharge flow rate and the control output is obtained by using the functional relationship between the control output and time and the functional relationship between the material weight and time. The discharge flow rate can be precisely controlled by directly selecting or inputting a value of the control output, to achieve the objectives of direct controlling and of avoiding the time for data stabilization.
