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.

Description

TECHNICAL FIELD

[0001] The present application belongs to the field of agricultural machinery, in particular to a hydraulic adjustable width range of raking machine. BACKGROUND

[0002] The existing three-row raking machine is composed of a middle raking mechanism and side raking mechanisms on both sides of the middle raking mechanism. The distance between the side raking mechanisms and the middle raking mechanism can only be manually adjusted, that is, the raking width can only be manually adjusted, which is extremely inconvenient to operate, time-consuming and laborious during operation, and inconvenient to move and transport. SUMMARY

[0003] The purpose of the present application is to solve the problem of the existing three-row raking machine that the raking width can only be manually adjusted, which is extremely inconvenient to operate, time-consuming and laborious during operation, and inconvenient to transport.

[0004] In order to achieve the above purpose, the present application adopts the following technical scheme:

[0005] A hydraulic adjustable width raking machine is composed of a middle raking mechanism and side raking mechanisms on both sides of the middle raking mechanism. The middle raking mechanism is fixed on a frame, and the frame is connected with a walking machine. The middle raking mechanism has a first cross beam, and the side raking mechanisms have second cross beams.

[0006] The second cross beams of the two side raking mechanisms are sleeved on both ends of the first cross beam of the middle raking mechanism. A telescopic oil cylinder is arranged between the first cross beam of the middle raking mechanism and the second cross beams of the two side raking mechanisms. The oil inlet pipe of the telescopic oil cylinder is in communication with a hydraulic synchronous split-flow motor, the hydraulic synchronous split-flow motor is in communication with the hydraulic system of the walking machine, and the oil outlet pipe of the telescopic oil cylinder is in communication with the hydraulic system of the walking machine.

[0007] The second cross beams of the two side raking mechanisms are tubular cross beams, and the two ends of the first cross beam are sleeved in the second cross beams on both sides.

[0008] The first cross beam is a tubular cross beam, and the second cross beams of the two side raking mechanisms are sleeved in the two ends of the first cross beam.

[0009] The working process of the present application is as follows:

[0010] The telescopic oil cylinder works, which can make the two side raking mechanisms synchronously extend and retract, and further adjust the working width, so that the widths on both sides are consistent.

[0011] The present application has the following advantages:

[0012] The telescopic oil cylinder works, which can make the two side raking mechanisms synchronously extend and retract, and further adjust the working width, so that the widths on both sides are consistent.

[0013] The hydraulic synchronous split-flow motor can make the two side raking mechanisms synchronously extend and retract, adjust the range uniformly, and has high adjustment accuracy.

[0014] The two side raking mechanisms can be retracted inwards by the telescopic oil cylinders, so that the overall width is reduced, and the moving and transporting are facilitated. BRIEF DESCRIPTION OF DRAWINGS
