Abstract
Description
Technical Field
[0001] This utility model relates to the field of cotton harvester technology, and in particular to an oil-free bearing for the cotton harvester baling bin and the baling bin itself. Background Technology
[0002] Cotton cultivation is widespread in my country. Previously, cotton harvesting relied primarily on manual labor, which was labor-intensive and inefficient. With the continuous improvement of agricultural mechanization in my country, large-scale machine-harvested cotton has become an inevitable trend in the cotton industry, leading to the emergence of cotton harvesters on the market. Using cotton harvesters can effectively increase harvesting speed and generate higher incomes for cotton harvesters. The main structure of a cotton harvester includes a frame, a harvesting head, a cotton collection bin, and a baling bin. During operation, the harvesting head collects cotton, which is then transported to the cotton collection bin and finally to the baling bin for packing.
[0003] To ensure the normal rotation of the cotton guide roller, lubricating oil or grease needs to be added to the bearings regularly to ensure their proper operation. However, this method is rather cumbersome. Moreover, as the cotton harvester's baling bin is affected by its working environment, dust and cotton lint from the cotton field can easily get into the bearings, contaminating the lubricating oil and affecting their normal use. Utility Model Content
[0004] To address the aforementioned problems, the purpose of this utility model is to provide an oil-free bearing for the cotton harvester's baling bin and the baling bin itself, which eliminates the need for oiling, is easy to operate, and prevents the high levels of lubricating oil in the bearing from becoming contaminated.
[0005] To solve the above-mentioned technical problems, the first technical solution adopted by this utility model is as follows: an oil-free bearing for a cotton harvester baling bin, having an inner ring and an outer ring, a liquid storage block provided between the inner ring and the outer ring, a sealing cap provided on both sides of the liquid storage block, a limiting groove provided on the inner side of the outer ring, and the liquid storage block embedded in the limiting groove.
[0006] In the above technical solution, the liquid storage block is made of oil-saturated polymer.
[0007] In the above technical solution, the liquid storage block is made of sponge.
[0008] In the above technical solution, an insert groove is provided at the inner edge of the outer ring, and the edge of the sealing cap is fitted into the insert groove.
[0009] In the above technical solution, the oil storage block is annular and is arranged close to the inner wall surface of the inner and outer rings.
[0010] To achieve the above objectives, the second technical solution of this utility model is: a packing bin for a cotton harvester that does not require oiling, comprising a bin body, a cotton guide roller provided inside the bin body, a cotton guide belt mounted on the cotton guide roller, the aforementioned oil-free bearings provided at both ends of the cotton guide roller, and bearing frames provided on both sides of the bin body, with the oil-free bearings mounted on the bearing frames.
[0011] In the above technical solution, the outer side of the oil-free bearing is provided with a sealed dust cover.
[0012] In summary, the advantages of using the technical solution of this utility model compared to traditional technical means are as follows:
[0013] This invention employs an oil-free bearing. During operation, the temperature of the guide roller rises under the action of the guide belt, causing the lubricating liquid storage block to expand and be squeezed out to achieve lubrication. When the guide roller stops working, the temperature drops and the lubricating liquid storage block absorbs the lubricating liquid back in. Throughout the process, the lubricating liquid is not lost, and the lubricating liquid retention is very high. There is no need for regular maintenance to ensure the oil level. Moreover, the storage block occupies all the remaining space inside the bearing. In addition, the sealing caps on both sides of the bearing can effectively prevent contaminants from entering the bearing, even in dusty environments such as cotton mills, thus extending the service life of the bearing.
