摘要： A header for a combine harvester includes a conveyor belt for conveying crop material in a conveyance direction, and an adjusting device for adjusting a tension of the conveyor belt. The adjusting device includes a cable that is movable with respect to a frame member of the header. A portion of the cable that is either directly or indirectly attached to one end of a roller for the conveyor belt extends either parallel to or substantially parallel to a tensioning direction of the conveyor belt for adjusting the tension of the conveyor belt. The conveyor belt may be an infeed conveyor belt or a lateral conveyor belt of a draper header, for example.

摘要： A method for pre-tensioning a chain conveyor, the method relating to a chain strand which is deflected by at least one chain wheel, wherein at least one measurement module is integrated in the chain strand and transmits data wirelessly to a communication device arranged outside the chain strand. The pre-tensioning force is adjusted according to the data collected and transmitted wirelessly by the measurement module.

摘要： A belt cooking apparatus (10) includes a lower frame structure (12) and an upper frame structure (14) in registry with the lower frame structure. A lower cooking conveyor belt (16) is supported by the lower frame structure (12) and correspondingly an upper conveyor belt (18) is supported by the upper frame structure (14). Heating element assemblies (20) are mounted on the lower frame structure (12) just below the lower cooking belt (16) as well as on the upper frame structure (14) just above the upper cooking belt (18). Food products are cooked while positioned between the upper and lower moving cooking conveyor belts (16) and (18) by heat generated by the heating element assemblies (20) while being advanced by the conveyor belts.

摘要： The present invention discloses a drive system of a scraper conveyor and a control method. The drive system includes a nose sprocket, a tail sprocket, a nose sprocket drive mechanism, and a tail sprocket drive mechanism, where the nose sprocket drive mechanism is a hydraulic motor I, and the tail sprocket drive mechanism is a hydraulic motor II; and a hydraulic system that drives the hydraulic motor I and a hydraulic system that drives the hydraulic motor II include same hydraulic elements, and both include a three-position four-way solenoid directional valve, a two-position two-way solenoid directional valve, a two-position three-way solenoid directional valve, an accumulator, and an oil supplement valve group. The present invention is applicable to rapid starting and stopping of the scraper conveyor in a heavy load status while adjusting chain tension in real time, thereby resolving a power imbalance problem in a dual-drive system, and has a simple structure and a long service life.

摘要： A belt conveyor, particularly a weighing belt conveyor includes a frame constructed from at least one side member and at least one cross member or from a supporting plate. Two rollers are mounted on the frame, with an endless belt located around the two rollers whereby the two rollers are mounted in such a way that they can be moved relative to each other in the conveyance direction. At least one adjustment device is provided on the frame for adjusting the separation between the two rollers. The adjustment device includes a rotatable adjusting component, the axis of rotation S of which lies obliquely above or obliquely below the conveyor level at an angle greater than 0° and less than 90°, in order to make an adjustment to the belt tension possible even after the endless belt has been installed.

摘要： The belt conveyance device includes a plurality of rollers, a belt, a meandering correction part, and an adjustment part. The rollers are disposed at intervals each other and rotate around axes. The belt is disposed around the plurality of rollers and travels. The meandering correction part shifts one end portion in an axial direction of a tension roller included in the plurality of rollers in a radial direction within a predetermined range to correct a meandering of the belt. The adjustment part shifts the other end portion in the axial direction of the tension roller in the radial direction such that a position of the one end portion of the tension roller is variable under a state where the meandering of the belt is corrected.

摘要： A conveyor assembly includes a conveyor module including first and second roller bodies and a conveyor belt; a chassis; and a tensioning system. The tensioning system is operable to adjust the tension of the conveyor belt and includes a tensioning device selectively shiftably mounted to the chassis such that shifting of the tensioning system in the fore-aft direction along the chassis results in corresponding fore-aft shifting of the first roller body relative to the second roller body, thereby facilitating adjustment of the tension of the conveyor belt. The chassis includes a pair of side rails and a slider bed. A stiffening assembly includes a bracket spaced vertically below the slider bed such that a vertical gap is formed between the slider bed and the bracket. The stiffening assembly further includes an insert disposed on the bracket and extending upward across at least a portion of the gap.

摘要： A dynamic belt-tensioning apparatus for a treadmill includes a base having a first end and a second end spaced from the first end. A foot-striking platform is movably supported by the base so as to allow vertical movement of the platform during operation of the treadmill. A drive belt has a fixed circumference and is positioned above a top portion of the platform. A drive roller is pivotally mounted adjacent to the first end of the base and engages the drive belt. A tensioning roller is pivotally mounted to the base and is capable of a range of movement to provide substantially constant tension to the drive belt in response vertical movement of the platform.
