AI Technical Summary
The existing cotton harvester's fan system requires multiple independent hydraulic motors for drive, which takes up a lot of space and is not stable enough.
Multiple fan shafts are connected by a coupling device via splines and a floating frame. Multiple fans are driven by a single hydraulic motor. The fan shafts are flexibly connected by buffer components. The coupling device is added to achieve adaptive floating.
This achieves a simplified structure for the wind turbine system, resulting in a smaller footprint, better stability, and avoidance of rigid damage.

Description
TECHNICAL FIELD
[0001] The utility model relates to cotton picker technical field especially is related to a cotton picker linkage fan. BACKGROUND
[0002] The cotton planting range in China is quite extensive, and the cotton picking mainly relies on manpower before, which has great labor intensity and very low efficiency. With the continuous improvement of agricultural mechanization level in China, developing large-scale machine picking cotton has become the general trend of China's cotton industry, so the cotton picker appears in the market. Through the use of cotton picker, the cotton picking speed can be effectively improved, and higher income is created for cotton picker. The main structure of the cotton picker includes a frame, a picking head, a cotton collecting bin and a packing bin. The picking head collects cotton, the collected cotton is transported to the cotton collecting bin, and then the cotton is sent to the packing bin for packing.
[0003] In the prior art, the cotton picker needs to suck the cotton at the cotton picking head by the fan and transport it to the cotton box. Generally, one fan drives two to three cotton picking heads, and each fan is driven by an independent hydraulic motor, which occupies a large space. UTILITARIAN CONTENT
[0004] In view of the above problems, the utility model aims at providing a cotton picker linkage fan structure which is more compact, occupies less space and has better stability.
[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme: a cotton picker linkage fan has a driving mechanism and a fan. The driving mechanism is used to drive multiple fans. The fan shafts of the fans are connected in series through a shaft coupling device. The shaft coupling device includes a spline and a floating frame. The floating frame is provided with a buffer on both sides. The fan shaft is mounted on the shaft coupling device through the spline. The spline side protruding key is clamped in the slot on the buffer.
[0006] In the above technical scheme, the driving mechanism is a hydraulic motor, and the output shaft of the hydraulic motor is drivingly connected to the first fan.
[0007] In the above technical scheme, the floating frame is provided with a mounting slot on both sides, and the buffer is embedded in the mounting slot.
[0008] In the above technical scheme, the buffer is a ring formed by a plurality of cylindrical bodies connected in series, and the material is rubber.
[0009] In the above technical scheme, the protruding key on the spline side is clamped in the slot between the cylindrical bodies.
[0010] In the above technical scheme, the fan is provided with a shunt pipe on the air outlet.
[0011] In summary, the advantages of the technical solution of this utility model compared with traditional technical means are as follows: This utility model adds a coupling device between the fans, which can drive multiple fans through a single hydraulic motor. The structure is more streamlined and occupies less space. The coupling device adopts a floating structure, and the spline and the floating frame are flexibly connected by a buffer. The two adjacent fans can adaptively float up and down, avoiding rigid damage and improving stability. Attached Figure Description
