Description

Technical Field

[0001] The utility model relates to the technical field of cotton picker manufacturing, in particular to a towed cotton picker with a master control structure. Background Art

[0002] The cotton planting area in China is quite extensive. In the past, cotton picking mainly relied on manual labor, with high labor intensity and low efficiency. With the continuous improvement of the level of agricultural mechanization in China, the development of large-scale machine-picked cotton has become an irresistible trend in the cotton industry in China. Therefore, cotton pickers have emerged on the market. By using a cotton picker, the cotton picking speed can be effectively increased, creating higher income for cotton pickers. When in use, cotton is first picked by the cotton picking head and then temporarily stored in the cotton collection bin. When it accumulates to a certain extent, it is taken out all at once. In the prior art, general cotton collection machines generally adopt multiple sets of transmission systems, which are respectively used to control the cotton collection box, the fan, and the wheel running. However, this structure requires multiple groups of driving mechanisms to achieve control, greatly increasing the volume and cost. Content of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to provide a driving mechanism for a towed cotton picker with a more concise structure, smaller volume and lower cost.

[0004] In order to solve the above technical problems, the technical scheme adopted by the utility model is as follows: A towed cotton picker with a master control structure, which has a towing head, a vehicle frame and a cotton collection bin. A master control structure is connected to the towing head. The master control structure includes a transfer case and a cotton picking pump, a fan pump and a system pump connected to the transfer case. An active gear, a first driven gear and a second driven gear are arranged in the transfer case. The active gear is in transmission connection with the main shaft of the towing head. The first driven gear and the second driven gear are meshed with the active gear. The first driven gear is in transmission connection with the cotton picking pump. The second driven gear is in transmission connection with the fan pump and the system pump. The fan pump controls the cotton suction fan on the cotton collection bin. The cotton picking pump controls the cotton picking head at the front end of the vehicle frame.

[0005] In the above technical scheme, a solenoid valve is arranged on the fan pump.

[0006] In the above technical scheme, the oil cylinders involved in the turning over of the cotton collection bin and the opening of the cover of the cotton collection bin on the cotton collection bin are controlled by the system pump.

[0007] In the above technical scheme, the steering oil cylinder involved in vehicle steering is controlled by the system pump.

[0008] In the above technical scheme, a cotton picking head lifting device is arranged on the vehicle frame. The lifting oil cylinder involved in the cotton picking head lifting device is controlled by the system pump.

[0009] In the above technical scheme, the fan pump and the system pump are connected in series, and a spline shaft is arranged between the fan pump and the system pump.

[0010] In the above technical solution, the driving gear is drivingly connected to the main shaft through a spline.

[0011] In summary, the beneficial effects of adopting the technical solution of the present utility model compared with the traditional technical means are as follows: The present utility model controls the cotton sucking fan, the cotton picking head, the steering, the lifting of the cotton picking head, and the opening and closing of the cotton collecting bin for discharging through the master control structure, which is realized by using a set of driving system in cooperation with a transfer case. The transfer case synchronously controls three pumps, namely the fan pump, the picking head pump, and the system pump, and then further controls the relevant structures. The structure is simpler and more compact, saving costs. Brief Description of the Drawings
