Full-feed type combine-harvester threshing cylinder

Abstract

The invention provides a full-feed type combine-harvester threshing cylinder. A plurality of independent cylinder teeth are evenly arranged on the circumferential surface of a cylinder body. Lengthened screw rods are arranged at the root of each cylinder tooth and are fixedly mounted by screwing nuts from the inside of the cylinder body. The cylinder teeth are formed by forging of 45# materials and are integrated with anti-twining pieces therein, and gaps are not formed between the anti-twining pieces and the cylinder teeth. The center of each cylinder tooth is tapered, the raised top end of each cylinder tooth is in the shape of a circular arc, and two sides of each cylinder tooth form a symmetrical shape structure. Adjustment cushion blocks are arranged between the roots of the cylinder teeth and the cylinder body. Every six cylinder teeth are evenly distrusted on the circumferential surface of the cylinder body circumferentially, and rows are formed by vertical arrayed cylinder teeth. The full-feed type combine-harvester threshing cylinder has the advantages that the cylinder teeth are independent teeth, the cylinder teeth are formed by forging of 45# materials, the lengthened screw rods are arranged at the roots of the teeth, the teeth can be mounted and demounted individually, and maintenance is facilitated; the integrally forged structure is adopted, production cost is lower, the overall strength of the cylinder teeth is higher, and the anti-twining pieces and the external teeth are integrated to prevent grass twining at the gaps among the cylinder teeth.

Description

technical field [0001] The invention relates to the field of full-feed combine harvesters, in particular to a full-feed combine harvester threshing drum. Background technique [0002] The threshing drum is the core part of the threshing part of the combine harvester. When harvesting, the rice straw is transported to the threshing chamber by the conveyor belt, and the rotation of the rice straw is driven by the roller and the impact of the filter screen is blocked to achieve the separation effect of rice straw and grain. At present, the threshing drum of the full-feed harvester is mainly a closed nail-tooth drum. This type of drum is welded side by side on the tooth plate by multiple pieces of nail teeth. The tooth plate is installed outside the drum. The drum teeth are vulnerable parts. When the tooth plate When the teeth are worn or damaged, the entire tooth plate needs to be replaced, and the maintenance cost for the user is high; the gap between the drum and the filter sc...

Problems solved by technology

[0003] In view of the large operating load of the threshing section drum of the existing full-feed combine harvester at home and abroad, and the fragile teeth of the drum, the present invention aims to provide a full-feed combine harvester threshing drum, so that the threshing section can meet the requirements of crop harvesting under different environmental conditions. Threshing needs, to achieve the best threshing effect
