[0002] Straw is a general term for the stems and leaves (ears) of mature crops, usually referring to the remaining parts of wheat straw, corn stalks, sorghum stalks, rice straw, bean stalks and other crops (usually coarse grains) after the seeds are harvested. More than half of the products of crop photosynthesis are stored in the straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. When the straw is processed, if the straw contains hard objects such as stones, it is easy to damage the processing equipment. For this reason, we need to screen the straw before processing to remove the stones and other debris contained in the straw to prevent the machine from being damaged when processing the straw. At present, the debris in a bundle of straw is removed by manual shaking, which will increase the labor intensity of workers. For this reason, we have proposed a crop straw remover.
