Description

Cotton picker fan assembly and cotton picker thereof Technical Field The utility model relates to the technical field of cotton pickers, in particular to a cotton picker fan assembly and a cotton picker thereof. Background The cotton planting range in China is quite wide, the picking of the cotton in the past mainly depends on hands, the labor intensity is high, and the efficiency is low. With the continuous improvement of the agricultural mechanical level in China, the development of large-scale cotton picking is a trend of cotton industry in China, so that cotton pickers appear on the market. By using the 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 comprises a frame, a cotton picking head, a cotton collecting bin and a packing bin, when the cotton picker is used, the cotton picking head is used for picking cotton, the picked cotton is conveyed into the cotton collecting bin, and then the cotton is conveyed into the packing bin for packing. In the prior art, cotton at cotton picking heads is required to be sucked by a fan and conveyed to a cotton box, two to three cotton picking heads are driven by one fan in general, each fan is driven by an independent hydraulic motor, the working environment of the cotton picking machine is a cotton field, a plurality of cotton rods and dust are arranged on a frame, sundries are prevented from entering the cotton box and the packing box in order to ensure the cleanliness of the frame, so that a cleaning impurity removing fan is also specially arranged on the frame, and the frame is blown to clean the upper part of the frame at regular intervals, but the structure is too complicated, and the structure occupies a larger space. Disclosure of utility model Aiming at the problems, the utility model aims to provide the cotton picker fan assembly and the cotton picker thereof, the fan assembly has more simplified structure and smaller occupied space, and the upper part of the frame is effectively cleaned. In order to solve the technical problems, the first technical scheme includes that the cotton picker fan assembly comprises a driving mechanism and fans, wherein the driving mechanism is used for driving a plurality of fans, fan shafts of the fans are connected in series through a coupling device, a shunt pipe is arranged on an air outlet of each fan, splines are arranged at the end parts of the fan shafts, the splines at the two ends of the coupling device are respectively connected with adjacent fan shafts, the coupling device comprises a retainer, buffer pieces are arranged at the two sides of the retainer, and convex keys at one side of each spline are clamped in grooves in the buffer pieces. In the above technical scheme, the driving mechanism is a hydraulic motor, and an output shaft of the hydraulic motor is connected to a fan shaft of the first fan in a transmission manner. In the above technical scheme, both sides of the retainer are provided with mounting grooves, and the buffer member is mounted in the mounting grooves. In the above technical scheme, the buffer member is annular that a plurality of cylinders link to each other, and the material is rubber. In order to solve the technical problems, the second technical scheme adopted by the utility model is that the cotton picker is provided with a frame, the front end of the frame is provided with a cotton picking head, the rear part of the frame is provided with a cotton box, the frame is provided with the fan assembly, the shunt pipe is used for being connected with a cleaning head and the cotton picking head, and the cleaning head faces to the upper part of the frame.
