Description
Technical Field
The utility model relates to the technical field of manufacturing of parts of harvesters, in particular to an anti-falling concave plate sieve device.
Background
The harvester is one of the agricultural machines which are mainly supported in China, and the technical level of the whole industry of the harvester is not high due to the late development of agricultural machines and the laggard technical level of developed countries in China and the laggard matching technology of the industry of the harvester in China. The basic technical requirement of the harvester is to ensure that the grains can be operated smoothly and efficiently under the condition of reaching the national specified technical indexes. The concave sieve plate is an important mechanism for threshing of the harvester, the existing concave sieve plate is mostly formed by splicing a plurality of left half concave sieve and right half concave sieve through bolts, and when the harvester works, the concave sieve plate is easy to shift abnormally and slip due to extrusion, so that the maintenance cost is increased.
