DETAILED DESCRIPTION

[0025] like Figure 1-Figure 4 As shown, this embodiment provides a new cotton picking machine cotton discharge mechanism, including a frame 1 and a driving motor providing power.

[0026] like Figure 1 As shown, the frame 1 includes a cotton discharge device and a conveyor belt 7 disposed at the bottom of the cotton discharge device. A cotton discharge roller 3 is disposed at the rear end of the conveyor belt 7 in the conveying direction. The cotton discharge device is composed of two side panels 4, a bottom panel 6, and a rear panel 5. The side panels 4 are perpendicular to the bottom panel 6 and the rear panel 5, respectively, and the angle formed by the connection between the rear panel 5 and the bottom panel 6 is an obtuse angle. The cross-section of the portion of the side panel 4 connecting to the cotton discharge roller 3 is a right-angled trapezoid. The bracket 2 is disposed at the end position where the lower base of the right-angled trapezoid connects to the right-angled side. A conveyor roller 8 is disposed on the inner side of the conveyor belt 7. The ends of the conveyor roller 8 are rotatably connected to the side panels 4 of the cotton discharge device via a second transmission shaft 13.

[0027] Specifically, such as Figure 2 As shown, a guide rail groove is provided on the outer circumference of the cotton discharge roller 3, and a cotton discharge tooth plate 9 is provided in the guide rail groove. A baffle is provided on the top of the guide rail groove to make the guide rail groove have a concave cross-section, and the cotton discharge tooth plates 9 are arranged at 30 degree intervals along the circumference of the cotton discharge roller 3; an axial telescopic spring 11 is provided between the cotton discharge tooth plate 9 and the cotton discharge roller 3, and the axial telescopic spring 11 limits the displacement distance through the baffle; the axial telescopic spring 11 is tightly connected to the cotton discharge tooth plate 9 and the roller body 10, and the height of the cotton discharge tooth plate 9 exposed to the roller body 10 is achieved by adjusting the axial telescopic spring 11, so that the accumulated and blocked cotton can be discharged in time, thereby ensuring the efficiency and uniformity of cotton discharge.

[0028] like Figure 1 and Figure 4 As shown, the cotton discharge roller 3 is arranged on the first transmission shaft 12 , and is arranged between the two side plates 4 of the cotton discharge device through the first transmission shaft 12 , and is rotationally connected to the side plates 4 through the first transmission shaft 12 .

[0029] Specifically, such as Figure 3 As shown, the discharge rollers 3 comprise a set of active rollers and six sets of passive rollers, which rotate synchronously. The bracket 2 is connected to the active rollers, which are arranged in a "U" shape, enabling more efficient combing. This "U"-shaped arrangement also reduces mechanical wear and extends the service life of the equipment.

[0030] Transmission gears are provided at both ends of the first transmission shaft 12, and an idler wheel is provided between two adjacent sets of transmission gears. The idler wheels are used to realize the common movement of the seven cotton discharge rollers 3, which is beneficial to breaking up the transported seed cotton and making the seed cotton more uniform during the cotton discharge process.

[0031] like Figure 3 As shown, the transmission gear of the active cotton roller is connected to the drive motor through a coupling. By controlling the rotation speed of the active cotton roller, the rotation speed of each cotton discharge roller 3 is adjusted, thereby changing the looseness of the seed cotton and reducing the probability of blockage during the seed cotton transportation process.

[0032] The utility model also provides a cotton picker, comprising a vehicle frame and a cotton discharge mechanism arranged on the vehicle frame. The cotton discharge mechanism of the cotton picker adopts the novel cotton discharge mechanism and vehicle frame of the cotton picker described in the first embodiment.

[0033] The working principle of the present invention is as follows: seed cotton falls into the cotton discharge device from the cotton collecting box located above the cotton discharge mechanism. Under the blocking effect of the cotton discharge roller 3, the seed cotton begins to be affected by the cotton discharge roller 3. In this process, the active cotton roller is driven to rotate by the driving motor, and the active cotton roller and the driven cotton roller and the seven groups of cotton discharge rollers 3 can be realized together by the idler wheel, which is conducive to breaking up the seed cotton falling from the cotton collecting box above, so that the fallen seed cotton becomes more uniform.

[0034] By controlling the speed of the active cotton roller through the drive motor, the speed of the other six groups of driven cotton rollers can be controlled, thereby changing the looseness of the seed cotton and reducing the probability of blockage during seed cotton transportation. The cotton discharge speed is also controlled by changing the height of the cotton discharge tooth plate 9 relative to the roller body 10. If the seed cotton accumulates at the outlet or the amount of seed cotton at the outlet is quite large, the seed cotton delivery rate can be reduced, that is, the height of the cotton discharge tooth plate 9 relative to the roller body 10 can be lowered.

[0035] Although the above describes the specific implementation methods of the present disclosure in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present disclosure. Those skilled in the art should understand that on the basis of the technical solution of the present disclosure, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present disclosure.
