[0027] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0028] like Figures 1-7As shown, a ground-level cotton picking machine includes a frame 1. A traction frame 25 is located at the front end of the frame 1, with depth-limiting wheels 27 installed at the bottom of the traction frame 25. Traveling wheels 26 are located at the bottom of the frame 1. A picking roller 2 is installed at the bottom front end of the frame 1. A cleaning filter 3 is obliquely installed on the frame 1 above and behind the picking roller 2. A spiral roller 4 and several toothed rollers 5 are installed from bottom to top on the frame 1 above the cleaning filter 3. Spiral blades 6 in opposite directions are located on both sides of the spiral roller 4, and several levers 7 are located in the middle. The toothed rollers 5 are located above and behind... A number of barbed rollers 8 are installed on the square frame. A number of brush rollers 9 are installed on the frame below the barbed rollers 8. A number of cotton-pulling rollers 10 are installed on the frame above the barbed rollers 8. A hopper 11 is installed on the frame behind the top cotton-pulling roller 10. A protective cover 12 is provided above the cotton-pulling rollers 10, barbed rollers 8, brush rollers 9, toothed rollers 5, spiral rollers 4, and pickup rollers 2. The ends of the cotton-pulling rollers 10, barbed rollers 8, brush rollers 9, toothed rollers 5, spiral rollers 4, and pickup rollers 2 are connected to the drive device through a transmission mechanism.

[0029] The pickup roller 2 includes a round shaft with several U-shaped grooves 13 evenly welded along the circumference. A brush seat 14 is installed in the U-shaped groove 13. The brush seat 14 is fixedly connected to the U-shaped groove 13 by several bolts on the side of the U-shaped groove 13, which facilitates disassembly and replacement after damage. The brush seat 14 is provided with several long brushes 15. The long brushes 15 have a certain degree of flexibility and will only pick up lighter objects such as cotton, cotton leaves, and weeds. They are not easy to pick up heavy objects such as cotton stalks, which facilitates the subsequent cotton separation.

[0030] The spiral blades 6 on both sides of the spiral roller 4 are used to gather the cotton towards the center and convey it backward through the lever 7, thus preventing the cotton from being squeezed into the gaps on both sides.

[0031] The toothed roller 5 includes a round shaft with several teeth evenly arranged along the circumference of the shaft, which can perform preliminary separation of impurities.

[0032] The barbed roller 8 includes a round shaft with several annular barbed toothed rings mounted on it. When the barbed toothed rings rotate, they can peel weeds and other vegetation downwards.

[0033] The cotton-dispensing roller 10 includes a round shaft, on which several fixed fins 16 are evenly installed along the circumference. Reinforcing ribs 17 are provided between adjacent fixed fins 16. Several elongated holes 18 are provided on the fixed fins 16. Brush seats 14 are installed at the elongated holes 18 by bolts. The installation position of the brush seats 14 can be adjusted within the elongated holes 18, thereby facilitating the adjustment of the assembly gap with the barbed roller 8 and reducing the assembly difficulty. Several short brushes 19 are provided on the brush seats 14.

[0034] The hopper 11 is a side-tipping hopper. The top of one side of the hopper 11 is connected to the frame 1 via a rotating shaft. Tilting cylinders 20 are respectively provided between the front and rear ends of the hopper 11 and the frame 1.

[0035] The drive device includes a gearbox 21 installed at the front end of the frame 1. A power shaft 22 is provided on the front side of the gearbox 21. A transmission shaft 23 is connected to both sides of the gearbox 21. One transmission shaft 23 is connected to the end of the pickup roller 2 via a transmission belt 24. The other transmission shaft 23 is connected to the end of the spiral roller 4 via a transmission belt 24. The end of the spiral roller 4 is then connected to the end of the toothed roller 5 via a transmission belt. The ends of several toothed rollers 5 are linked together via a transmission belt. One end of the uppermost toothed roller 5 drives several cotton-pulling rollers 10 in the same direction via a transmission belt, and drives several barbed rollers 8 in the opposite direction via a transmission belt. The other end of the uppermost toothed roller 5 drives several brush rollers 9 in the same direction via a transmission belt.

[0036] Working principle:

[0037] During operation, the device is connected to a tractor or other power unit via a traction frame 25. The power output shaft of the tractor is connected to the power shaft 22 on the front side of the gearbox 21. The tractor drives the entire device. When the power shaft 22 rotates, it drives the two transmission shafts 23 to rotate after being reversed by the gearbox 21. One transmission shaft 23 drives the pickup roller 2 to rotate via a transmission belt 24, and the other transmission shaft 23 drives the spiral roller 4 to rotate via a transmission belt 24. The pickup roller 2 picks up cotton from the ground and conveys it upwards to the spiral roller 4. When the spiral roller 4 rotates, the spiral blades 6 on both sides gather the cotton towards the center and convey it backwards to the toothed roller 5 via a lever 7. When roller 4 rotates, it simultaneously drives toothed roller 5 to rotate via a transmission belt. Toothed roller 5 conveys cotton backward and performs preliminary separation of impurities. When toothed roller 5 rotates, it drives several cotton-pulling rollers 10 and brush rollers 9 to rotate in the same direction, and drives several barbed rollers 8 to rotate in the opposite direction. The barbed rollers 8 rotate downward to peel weeds and other debris downward. The brush rollers 9 rotate below the barbed rollers 8 to peel weeds and other debris downward. The cotton-pulling rollers 10 rotate upward to convey cotton backward to hopper 11 for temporary storage. When hopper 11 is full, it can be moved to the unloading area. The hopper 11 is tilted 90 degrees by the tilting cylinder 20 to unload the cotton inside.

[0038] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.
