Description

Technical Field

[0001] The invention relates to the technical field of soybean combine harvesters, in particular to an explosion-proof pod soybean combine harvester. Background Art

[0002] The soybean combine harvester is a modern agricultural machine that integrates the functions of cutting, conveying, threshing, separating and cleaning. It cuts off the soybean plants through the cutting table and conveys them to the threshing device for threshing, and then separates and cleans the beans and impurities to achieve mechanization of soybean harvesting. The soybean combine harvester greatly improves the efficiency of soybean harvesting and reduces the labor intensity of farmers. It has a far-reaching impact on the scale and mechanization of soybean production. In soybean combine harvesters, the reel plays a vital role. The main functions of the reel include: moving the crops in front of the harvesting platform to the cutter, supporting the crop stalks to prevent the cutter from tilting forward when cutting, and pushing the crop stalks to the conveyor in time after cutting. The reel has various structural types, including ordinary pressure plate type and eccentric type, and is usually composed of components such as a paddle, tie rods and bearings. By adjusting the position and speed of the reel, it can adapt to different harvesting conditions to ensure harvesting efficiency and effect. Although the soybean combine harvester in the prior art has improved the efficiency of soybean harvesting to a certain extent, it still has some disadvantages. Among them, the reel, while supporting and conveying the crop straw, will produce a certain impact force on the soybean plant due to its rotation and striking action, causing the stems and pods to vibrate strongly, especially in the late stage of soybean maturity, when the pods have become dry and brittle.
