Roller for harvesting machinery

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a harvesting machinery roller which comprises a roller body, a threshing section is provided with a first plate tooth set and a second plate tooth set, the first plate tooth set comprises a plurality of first plate teeth evenly arranged in the circumferential direction of the roller body, and the second plate tooth set comprises a plurality of second plate teeth evenly arranged in the circumferential direction of the roller body. The first plate teeth are perpendicular to the axis of the roller body, and included angles are formed between the second plate teeth and the first plate teeth. A third plate tooth group and a fourth plate tooth group are arranged on the separation section, the third plate tooth group comprises a plurality of third plate teeth which are uniformly arranged in the circumferential direction of the roller main body, the fourth plate tooth group comprises fourth plate teeth which are uniformly arranged in the circumferential direction of the roller main body, the third plate teeth are parallel to the axis direction of the roller main body, and the fourth plate teeth and the third plate teeth are arranged at included angles. The corn thresher has the advantages that threshing is clean, power consumption is low, the material flowing speed is high, the harvesting efficiency is improved, and the roller is not blocked.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a drum for harvesting machinery. Background technique [0002] At present, domestic wheat harvesters are still based on the "tangential flow + horizontal axial flow" technical route, but due to the low operating efficiency and insufficient separation capacity of this technical route during harvesting, the development of products is restricted. Axial-flow rollers commonly used in the prior art include the following two types: (1) three-stage rollers of "grain rod + rod tooth + separation plate", that is, the groove rod, rod tooth and separation plate are arranged on the main body of the drum in sequence, and through three The segmented structure is used for threshing wheat. This kind of roller has the disadvantages of heavy roller load and easy damage. (2) Rod-tooth drum, which uses rod teeth for threshing and separation. After being treated by this type of drum, ...

Problems solved by technology

This type of roller has the disadvantages of large roller load and easy damage

(2) Rod-tooth drum, which uses rod teeth for threshing and separation. After being treated by this type of drum, the straw is relatively broken, and the drum has a strong separation ability, but the cleaning load is large and the loss is serious.
