[0035] The implementation principle of this application embodiment is as follows: When it is necessary to grab cotton bales, two cotton bales are placed at the bottom of the grabbing head 6. The grabbing machine body 5 is operated by the control panel 4 to move the grabbing head 6 horizontally back and forth in cooperation with the electric slide rail 2 and the electric slider 3. The two grabbing rollers at the bottom of the grabbing head 6 grab the cotton on the surface of the cotton bales back and forth. During the grabbing process, the grabbing head 6 lowers the two grabbing rollers through the lifting device 8 in the grabbing machine body 5, and the third motor 86 in the lifting device 8 is started. The output of the third motor 86 drives the double-headed worm gear 85 to rotate. The rotating double-headed worm gear 85 drives the two worm wheels 84 to rotate synchronously through the worm wheel grooves at both ends. The two rotating worm wheels 84 drive the two threaded rods 82 at the top to rotate. The two rotating threaded rods 82 drive the two lifting blocks 83 to slide up and down synchronously on the inner wall of the lifting column 81. The two sliding lifting blocks 83 together drive the cotton grabbing head 6 to move up and down. The two descending grabbing rollers grab the raw cotton into small cotton bundles in sequence, completing the cotton grabbing operation. When the multi-compartment cotton bin needs cotton, the grabbed cotton bundle is conveyed through the cotton conveying body 7 at the top of the cotton grabbing machine 5. The first motor 73 at one end of the cotton grabbing machine 5 is activated, and its output drives the impeller shaft 72 to rotate. This causes the impeller 70 to rotate inside the cotton conveying body 7, creating a circulating airflow. The airflow draws the cotton bundle and conveys it upwards through the hose 71 into the multi-compartment cotton bin. When the multi-compartment cotton bin is about to be full, a sensor inside the bin sends a signal to cut off the power to the first motor 73. While the impeller 70 in the cotton conveying body 7 is still rotating, a sensor inside the cotton conveying body 7 activates the second motor 88. The output of the second motor 88 drives the bidirectional threaded rod 87 to rotate. The rotating bidirectional threaded rod 87 drives two brake calipers 75 at different threads on the outer surface to perform opposing clamping movements, thereby causing the two friction plates 76 to jointly clamp and engage the rotating impeller shaft 72. One end of the two friction plates 76 continuously rubs the outer surface of the impeller shaft 72 to prevent the impeller shaft 72 from rotating or its tendency to rotate. The brake springs 78 at one end of the two connecting pins 77 are activated to ensure that the two friction plates 76 stably clamp the outer surface of the impeller shaft 72, increasing the braking torque, thereby achieving the purpose of braking the impeller shaft 72. The embodiments of this specific implementation are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. The same parts are indicated by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
