A square bale simulation elastic device

Abstract

The invention relates to a rectangular bale simulation elastic device, which comprises an elastic shell, a pressure regulation air bag, a control box and a scissors fork type supporting mechanism, wherein a cavity is arranged in the elastic shell; the cavity is supported by the scissors fork type supporting mechanism to support the elastic shell into the shape of the rectangular bale; the pressureregulation air bag is installed in the cavity; the scissors fork type supporting mechanism is driven by a servo motor, and the servo motor is controlled by a controller; and the pressure of the pressure regulation air bag is controlled by the controller. By use of the elastic shell, the scissors fork type supporting mechanism and the pressure regulation air bag, the mechanical property of the rectangular bale is simulated, and a whole test process is simplified.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a square bale simulation elastic device. Background technique [0002] The production efficiency of the square baler is high, and the density of the bales produced is relatively high. The square bales are also convenient for storage and transportation. In recent years, they have been widely used in the harvesting of forage and crop straw. As the core component of the square bale baler, the knotter is very complicated in its spatial structure and it is difficult to manufacture key parts. As a result, the knotters used in domestic balers generally rely on imports. The knotters imitated by domestic manufacturers have the problem of premature failure in the actual baling operation, which seriously restricts the harvesting efficiency of forage and straw, and increases the maintenance cost of the operation. [0003] In order to better study the working proce...
