Embodiment Construction
[0030] The present invention can be explained in more detail with reference to the following embodiments; however, the present invention is not limited to the combination of these embodiments.
[0031] The embodiments selected herein for the purpose of disclosing the present invention are currently considered suitable, but it should be understood that the present invention intends to include all changes and improvements of the embodiments within the scope of the present invention.
[0032] in figure 1 , 2 , 3, 4, and 5, the column-type flexible threshing method of the grain combine harvester;
[0033] This method is especially suitable for harvesting various grains such as wheat, rice, soybeans, etc.;
[0034] 1). When the crop is fed into the cut-flow drum 4 by the inclined conveyor, the drum 4 is grabbed by the column 3;
[0035] 2) After the column 3 grabs the crops, the contact head 1 and the ears of the grain are used for partial threshing; during threshing, the contact head 1 itse...

The invention relates to a grain combine column-typed flexible threshing method and a column-typed flexible threshing mechanism, belonging to the technical field of grain combines; the invention is particularly suitable for the harvest of various grains such as wheat, paddy rice, soybean and the like; when the crops are sent into a shear roller 4 by an inclined conveyor, the roller 4 captures thecrops by a cylinder 3; after the cylinder 3 captures the crops, partial threshing is carried out by the strike of a contact head 1 with the millet sprays; when in threshing, as the contact head 1 hassmooth size and shape, the impact strength of the material can be minimized; while the cylinder 3 is spirally arranged on the roller surface 5 of the roller 4, therefore, the cylinder 3 can effectively ensure the threshing separation effect of the grain and the millet sprays; through the method and the column-typed flexible threshing mechanism thereof, the excessive damage to the grain caused bydirect strike in the threshing process can be effectively avoided, the integrity of the grain is ensured to the most extent, thus being beneficial to reusing the grain as seed, and enhancing the storage life and the quality of the grain.
Description
Technical field [0001] The invention belongs to the technical field of grain combine harvesters, and particularly relates to a column-type flexible threshing method and a column-type flexible threshing mechanism of a grain combine harvester. Background technique [0002] The main function of the grain combine harvester is to complete the processes of harvesting, threshing, separating the stalks, and removing the surplus of cereal crops at one time, and directly obtain the grain from the field. Some grain combine harvesters can also harvest beans, sunflower and pasture seeds after partial modification and adjustment. Its advantages are high labor productivity, low labor intensity, and suitable for large-scale harvesting of crops when catching up with farmers. [0003] Existing grain combine harvesters can be divided into four types: self-propelled, tractor-drawn, suspended and semi-suspended according to different power configurations and coupling forms. According to the way the c...
