Abstract
Description
Technical Field
[0001] The utility model belongs to the field of agricultural machinery, and in particular relates to a lost cotton picking device. Background Art
[0002] In 2023, China's cotton planting area reached 41.8221 million mu (approximately 1.3 million hectares), of which 35.54 million mu (approximately 1.3 million hectares) were in Xinjiang, accounting for 84.98% of the country's total cotton planting area. Xinjiang also leads the nation in cotton production, reaching 5.112 million tons in 2023, accounting for 90.99% of the national total. The net cotton harvest rate of existing cotton pickers is generally around 90%-95%. This is primarily due to the influence of various factors during harvesting, such as operating speed, defoliation efficiency, plant growth posture, and weather. This results in a significant amount of cotton (hanging cotton, leftover cotton, naturally fallen cotton, and impact-dropped cotton, hereinafter referred to as "dropped cotton") being unable to be mechanically harvested. Consequently, 5%-10% of the cotton will remain in the fields after harvest. According to research, approximately 250,000 to 500,000 tons of cotton will be left in Xinjiang after mechanical harvesting in 2023, resulting in a significant waste of resources. The picking components in the existing lost cotton picking devices are mostly a combination of spring teeth and belts. Since the Xinjiang region has widely promoted the use of mulching technology and sub-film drip irrigation technology in cotton planting, the spring teeth are prone to pick up the mulch and drip irrigation belts during the rotation of the picking drum, which not only affects the quality and impurity content of the cotton, but may also be entangled in the machine and cause machine failure, and at the same time brings difficulties to the recovery of the mulch and drip irrigation belts.
[0003] Therefore, the applicant proposed a dropped cotton picking device with a simple structure, low failure rate, and the ability to efficiently pick up dropped cotton and reduce its impurity content. Summary of the Invention

The cotton pressing roller is provided at the front of the picking device to press down the cotton stalks during the movement of the picking device. The depth-limiting roller is provided below the picking device to adjust the height of the picking device.
[0006] As a further description of the above technical solution: the picking roller includes a fixed angle steel, a small disc, a picking belt and a large disc; the small disc is five parallel pieces, and the large disc is on both sides of the picking roller; the fixed angle steel is located between the large disc and the small disc, and is evenly spaced along the circumference; the ends of the fixed angle steel are fixedly connected to the large disc and the small disc on the corresponding side and the fixed angle steel passes through the large disc and the small disc; the picking belt is fixed to the fixed angle steel by bolts, and is evenly distributed along the axial direction of the fixed angle steel; the fixed angle steel rotates with the main shaft of the picking roller, thereby driving the picking belt on the fixed angle steel to rotate, thereby realizing the picking work.
[0007] As a further description of the above technical solution: there is an inclined cotton baffle on the upper right side of the thorn drum, the lower end of the cotton baffle faces the spiral auger, and the upper end is connected to the frame; there is another inclined cotton baffle on the left side of the thorn drum, the upper end of the cotton baffle faces the picking drum, and the lower end is connected to the debris removal screen; the debris removal screen is installed under the thorn drum.
[0008] As a further description of the above technical solution: the spiral auger is located at the rear end of the spike drum; an auger screen is provided below the spiral auger; and the left end of the auger screen is connected to the debris removal screen.
[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are: 1. The first innovation of the utility model is that all the picking components are replaced with a belt structure, which avoids the lifting of the ground film and drip irrigation belt during operation, and at the same time reduces the lint pulling phenomenon caused by the rotation of the rigid spring teeth, thereby improving the quality of the cotton; 2. The second innovation of the utility model is that the cleaning part of the picking device is optimized. Compared with the cleaning method of the existing picking device that combines a serrated roller, a cleaning brush and a cleaning rod, only the spiked roller is retained for rough cleaning, and the cotton is thrown into the subsequent cleaning mechanism for cleaning through a spiral auger, which reduces the machine failure rate and improves the working efficiency.
