Also found in: Dictionary, Thesaurus, Medical, Financial, Wikipedia.
a modification of a passenger-car chassis with an open body for carrying passengers and loads. Load-carrying capacity is usually 200-500 kg. For transporting passengers, a pickup may be equipped with a removable canvas top and folding benches along the sides.
the working part of an agricultural machine for picking up mowed agricultural crops, grass, and hay from windrows; it may also be used to pick up fallen cotton. Some pickups are separate attachments that are mounted on various machines, most often on grain combines. Others are working parts built into a machine, such as a pickup-stacker, pickup-ricker, or cotton-picking machine. A pickup that is mounted on a grain combine is driven by the combine’s engine. A pickup built into a machine pulled by a tractor is driven by the tractor’s power takeoff shaft. A distinction is made between drum, belt-conveyor, and brush-conveyor pickups.
A drum pickup has retractable spring pins and is covered by a cylindrical housing of plates between which spaces have been left for the turning of the pins. The pins emerge from the lower part of the housing, picking up the stems from the windrows and throwing them onto the housing. They gradually retract, enabling the stems to move toward the conveyor. This type of pickup may be in the form of an attachment (on a grain combine) or may be built into the machine (pickup-stacker, pickup-ricker).
The belt-conveyor pickup is manufactured as an attachment for a grain combine. The pickup mechanism consists of two conveyors made of rubberized canvas with cross belts and pick-ing-up spring pins. During the movement of the canvas, the pins lift the stems from the windrows and throw them on the auger conveyor of the combine’s reaper. Similar pickups, differing somewhat in design, are used abroad.
The cotton picking machine is equipped with a brush-conveyor picker. As the cotton is picked up from the ground, the machine removes the impurities from it. For thorough picking, the picker has shields that deflect the cotton plants to the side. The brushes rake the cotton out from under the shrubs and sweep it into the space between the rows, under the conveyors of the pickup. The conveyor belts place the cotton onto the drum, from the surface of which the dirt and other large impurities are dropped onto the field. In this manner, the cotton undergoes preliminary cleaning. The belts of the concentrator located over the hopper deliver the cleaned cotton to a conveyor that drops it into the hopper.
