Specifically, a rotating motor 17 is arranged on the cotton feeding horizontal conveyor 2, and the rotating motor 17 is in transmission fit with the end part of the rotating roller 3 to drive the rotating roller 3 to rotate. Wherein:
when the rotating rollers 3 in the cotton loosening roller group are arranged into two rows which are distributed in the front-back mode, a rotating motor 17 is arranged corresponding to each row of the rotating rollers 3, and at the moment, the rotating motor 17 is in transmission fit with one of the rotating rollers 3 located at the outermost side through a belt pulley assembly. Above the rotating roller 3 is provided a drive shaft which extends in the axial direction of the rotating roller 3 to pass over the outer rotating roller 3 and connects the remaining rotating roller 3 with the drive shaft through a pulley assembly. The drive shaft is rotatably mounted on the central rod 8.
Further, the end of the rotor 3 is provided with a seal cap 18, the driving gear set 12 is located inside the seal cap 18, and the seal cap 18 contacts on the top surface of the rotor 3. Specifically, the seal cover 18 is slidably fitted to the roller 3. After such an arrangement is made, the boot seal 18 prevents a significant amount of cotton from being caught in the drive gear set 12.
Wherein, the through groove of the embodiment of the application is provided with a circular hole, and the inner diameter of the channel 7 is matched with the outer diameter of the rake teeth 4. The channel 7 is arranged on a slide 19, which slide 19 is arranged on the rotor 3 in an axial sliding manner. At this time, when the tine 4 is displaced into the roller 3, the slider 19 can fade cotton on the surface of the tine 4 upward from the root of the tine 4. When the rake teeth 4 axially displace, the sliding blocks 19 displace in the side walls of the rotary roller 3, and the rotary roller 3 is kept in a closed state by combining the rake teeth 4, so that cotton is prevented from entering the rotary roller 3.
The two rows of rotating rollers 3 are staggered and distributed in the width direction of the cotton feeding horizontal conveyor 2, and at the moment, the rake teeth 4 can cover cotton in the width direction.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the application.
