Description

Technical Field

[0001] The utility model relates to a control system for a cotton picker packaging mechanism. Background Art

[0002] As cotton pickers or cotton pickers or cotton harvesters or cotton pickers, agricultural equipment or vehicles are called for the mechanized harvesting of cotton. Cotton pickers with spindles are the most common today. These machines work with a number of wet-toothed spindles that run on a rotating shaft and turn around themselves again. The spindles wind the cotton out of the bolls and deliver it to counter-rotating comb rollers. On other cotton harvesters, the spindles are positioned eccentrically on the shaft to scrape the cotton inside the machine. The cotton is then delivered to baskets, mainly by air pressure, where it is compressed and pre-compacted.

[0003] Existing cotton picker control systems usually use a hydraulic system to control the cylinder to achieve the laminating function. However, due to the different types of rocker arms, different hydraulic systems are usually required for control. This requires customizing different hydraulic systems for different types of rocker arms, which increases the work, and most hydraulic systems have complex structures. However, the laminating work itself does not require complex functions. Utility Model Content

[0004] The purpose of the utility model is to solve the above deficiencies in the prior art and provide a control system for a cotton picker baling mechanism.

[0005] A control system for a cotton picker baling mechanism, comprising:

[0006] A rocker arm cylinder, whose piston rod is connected to the rocker arm, and the rocker arm is connected to the packing belt;

[0007] A first hydraulic oil circuit, which is connected to the rod chamber of the rocker cylinder and the control valve respectively, and a one-way valve is provided on the first hydraulic oil circuit;

[0008] A second hydraulic oil circuit, which is respectively connected to the rodless chamber of the rocker cylinder and the control valve;

[0009] Control valve: It is connected to the hydraulic source and the oil return tank respectively.

[0010] Working principle: When power is on, the hydraulic source is connected to the first hydraulic oil circuit, and the second hydraulic oil circuit is connected to the return oil tank; when power is off, the solenoid valve switches direction, and when the pressure is large enough, the one-way valve allows the oil to flow in the opposite direction, then the first hydraulic oil circuit is connected to the return oil tank, and the second hydraulic oil circuit is connected to the hydraulic source.

[0011] In order to better control the flow direction of the hydraulic oil circuit, the control valve is a two-position four-way solenoid valve.

[0012] In order to control the hydraulic oil circuit, the one-way valve is a hydraulically controlled one-way valve.

[0013] Beneficial effects: Compared with the prior art, the utility model is composed of a two-two-four-way reversing valve and a hydraulically controlled one-way valve, which can meet the cotton picker packaging film conveying function, has a simple structure and is easy to operate.
