  • 4mz-3a control: the control system is simple, intuitive and easy to maintain. Three stage adjustable direction machine, more comfortable operation. Cotton box: large capacity two-stage lifting cotton box, which can effectively reduce the number of cotton unloading and improve the operation efficiency; the cotton box door is equipped with a touch protection device, when the protection device is pressed up, the door will not be opened to avoid damage to the machine and auxiliary equipment. Cotton picking head: the nail picking head is arranged horizontally, and the secondary clutch mechanism and blockage alarm sensor are arranged inside to better protect the picking head from damage; at present, the cotton picker can be equipped with Pro 12 and pro 16 cotton picking heads.
    Pro12 cotton picking head: there are 12 spindles on the front and back rollers, and there are 18 rows of spindles on each spindle picking seat pole;
    Pro16 cotton picking head: front roller has 16 pick-up seat rods, and rear drum has 12 picking seat rods. Each spindle picking seat rod has 20 rows of spindles. It can be selected according to different operation conditions. The 4mz-3a cotton picking head is driven by hydraulic pressure. The rotation speed and walking speed of the cotton picking head are flexibly controlled by the electric control pump and quantitative motor to ensure the speed and walking flexible control of the cotton picking head and ensure the accurate and stable transmission of the speed and walking speed of the cotton picking head. 4mz-3a cab: seat, control box and monitor are integrated and optimized by human engineering, which makes the operation more convenient.
