Hydraulic hayrake with adjustable amplitude and width

Abstract

A hydraulic hay rake with an adjustable width belongs to the field of agricultural machinery, and comprises a middle hay raking mechanism and side hay raking mechanisms positioned on two sides of the middle hay raking mechanism, the middle hay raking mechanism is fixed on a rack and is provided with a first cross beam, and the side hay raking mechanisms are provided with second cross beams; second beams of the two side hay raking mechanisms are sleeved with the two ends of a first beam of the middle hay raking mechanism in a penetrating mode, telescopic oil cylinders are arranged between the first beam of the middle hay raking mechanism and the second beams of the two side hay raking mechanisms, and oil inlet pipes of the telescopic oil cylinders are communicated with a hydraulic synchronous flow dividing motor. The hydraulic synchronous shunting motor is communicated with a hydraulic system of the walking machine; and an oil outlet pipe of the telescopic oil cylinder is communicated with the hydraulic system of the walking machine. The hydraulic synchronous shunting motor can enable the two side raking mechanisms to stretch out and draw back synchronously, the adjusting amplitude is unified, and the adjusting precision is high. The two side raking mechanisms can contract inwards through the telescopic oil cylinders, so that the overall width is reduced, and movement and transportation are facilitated.
