Description

Technical Field

[0001] This utility model relates to a combined brush roller for a light cotton picker, belonging to the technical field of components for cotton pickers (A01D 46 / 14). Background Technology

[0002] Cotton is an important economic crop in China and a crucial raw material for the textile industry. Existing tracked lightweight cotton harvesters are highly adaptable, having revolutionized the traditional horizontal spindle-type harvesting method. They offer advantages such as simple structure and ease of operation, and can meet the harvesting needs under my country's complex production conditions.

[0003] The brush roller harvesting device is a core component of a light cotton harvester, and its performance has a significant impact on the quality of cotton harvesting. For example, if the brush rollers in the brush roller harvesting device are in long-term contact with cotton stalks, friction and heat will accelerate the wear of the brushes, leading to straw entanglement and seed breakage on the brush rollers, resulting in a decrease in harvesting efficiency and affecting the lifespan of the machine. Summary of the Invention

[0004] The technical problem this invention aims to solve is how to avoid the rapid wear and tear of brush rollers in existing lightweight cotton harvesters, as well as the resulting issues of brush roller entanglement with straw, short working life, and low efficiency.

[0005] The technical solution proposed by this utility model to solve the above-mentioned technical problems is: a combined brush roller body for a light cotton harvester, including a mandrel, and multiple base plates are evenly distributed on the outer circumferential surface of the mandrel. Steel plate brushes and nylon brushes are respectively arranged on the multiple base plates, and the steel plate brushes and nylon brushes are arranged at intervals on the base plates along the inner circumferential direction of the cross-section of the mandrel.

[0006] Furthermore, the end of the steel brush that contacts the cotton has a folded edge, and the folded edge has a 5°-10° upturn at a distance of 20-30mm from the end edge of the steel brush.

[0007] Furthermore, the extended length of the steel plate brush is 10-15mm shorter than that of the nylon brush.

[0008] Furthermore, the nylon brush and the steel plate brush are arranged circumferentially spaced from each other on the base plate in a ratio of 4:2, 5:1, 4:2, 3:1 or 3:3 within the cross-section of the mandrel.

[0009] Furthermore, a hexagonal prism is fixed to the outside of the mandrel, and the base plate is fixed to the prism surface of the hexagonal prism or inserted into a groove opened on the prism surface of the hexagonal prism.

[0010] Furthermore, the steel plate brush is fixed to the base plate by bolts.

[0011] Furthermore, the nylon brush is fixed to the base plate by a pressure plate.

[0012] The beneficial effects of this utility model are as follows: 1) Because steel plate brushes and nylon brushes are arranged at intervals along the inner circumferential direction of the cross-section of the mandrel on multiple base plates on the outer circumferential surface of the mandrel, the existing single brush roller structure and working mode of the cotton harvester are changed, forming a brush roller body with a "rigid and flexible" combination of steel plate brushes and nylon brushes. This effectively avoids the rapid wear of the brush roller brushes, ensuring cotton brushing while solving the problems of grass entanglement and seed breakage on the brush roller, reducing the impurity content of seed cotton, and extending the working life of the brush roller and improving working efficiency. 2) Because the end of the steel plate brush that contacts the cotton has a folded edge and a raised shape, it can increase the strength of the steel plate brush, make it easier for the cotton stalk to pass through and reduce breakage, thus improving cotton harvesting efficiency. 3) Because the extension length of the steel plate brush is shorter than that of the nylon brush, it can further increase the cotton stalk passage and reduce the scraping of the cotton stalk. 4) By adjusting the ratio of steel plate brushes to nylon brushes and changing the extension length, it can adapt to the harvesting of different types of cotton.

[0016] This embodiment describes a combined brush roller body for a lightweight cotton harvester, such as... Figure 1 and Figure 2 As shown, it includes a mandrel 1, and multiple base plates 2 are evenly distributed on the outer circumferential surface of the mandrel 1. Steel brushes 3 and nylon brushes 4 are respectively provided on the multiple base plates 2. The steel brushes 3 and nylon brushes 4 are arranged at intervals on the base plates 2 along the inner circumferential direction of the cross-section of the mandrel 1.

[0017] In this embodiment, a hexagonal prism 6, mainly composed of six steel plates, is fixedly mounted on the outside of the mandrel 1. The mandrel 1 and the six steel plates can be fixed by welding. A base plate 2 is provided on the hexagonal prism 6. There are six base plates 2. The six base plates 2 are fixed to the six prism surfaces of the hexagonal prism 6 fixed on the outside of the mandrel 1 by bolts, or the six base plates 2 are directly welded to the six prism surfaces of the hexagonal prism 6, or six slots are opened on the six prism surfaces of the hexagonal prism 6, and the six base plates 2 are respectively inserted into the six slots and fixed by bolts.

[0018] In this embodiment, two steel plate brushes 3 are fixed to two base plates 2 by bolts; four nylon brushes are fixed to four base plates 2 by pressure plates 5; a steel plate brush 3 is arranged between two pairs of nylon brushes, so that the nylon brushes 4 and steel plate brushes 3 are arranged on the base plates 2 in a circumferential arrangement of 4:2 within the cross-section of the mandrel.
