At present, due to the chaos in the rural business channels, products on the thresher market are difficult to divide. Nowadays, the wheat thresher is nearing the peak of wheat harvesting. Here is a reminder for farmers who purchase threshers. Points: 1. Whether the thresher is complete or not. The "three certificates" include: production licenses, agricultural machinery promotion licenses, and product certifications. The first two certificates were issued by the state's full-time inspection agency after passing the inspection of the threshing mill's products and production conditions. They are intended to recommend reliable products for users. The certificate of conformity is a sign that the manufacturer has passed the inspection of the product. The thresher with "three certificates" can be purchased with confidence. Second, whether the thresher has safety warnings and protective measures. There should be a turn sign on the thresher, a permanent safety warning sign at the dangerous location, and a transmission safety guard. Feed inlets should ensure that the hands cannot touch the threshing cylinder during normal operation. Third, the threshing drum rotation is normal. By turning the threshing drum by hand, the thresher with good performance should be flexible, no abnormal noise, no jamming phenomenon, and should not always stop at a certain position after each rotation. (Marks can be drawn on the rotating parts with chalk , Observed by observation). Fourth, whether the annex is complete. Check whether the threshing machine has instructions for use, “Three Guarantees†measures, random accessories, and wearing parts. If not, the sales department or the manufacturer should be required to complete the threshing machine. In the course of use, the following operating procedures shall be strictly observed: 1. The wheat thresher operator must undergo professional training and hold an agricultural machinery operation certificate. 2. The threshing machine used in the game must be inspected by the agricultural machinery safety supervision department before use, and the use of the eliminated product should be prohibited. Third, to start and stop the machine, a signal must be given in advance and it must be operated by the operator. Other personnel must not operate it at will. During operation, the operator must not leave the machine without permission. Fourth, the transmission parts should be installed guards, drive belt joints should be solid, it is strictly prohibited to hand and other objects into the transmission site, not allowed to pick up the belt during the operation of the machine or leap from the belt. When troubleshooting, power should be cut off. 5. It is forbidden to replace the pulley or increase the original design speed. The operation of the thresher feeding chain is not allowed to be carried out. 6. Feeding should be uniform. Do not push the wheat directly into the drum with rice dumplings, wooden poles, and other tools to prevent feeding of hard objects such as stones, iron pieces, and wooden utensils into the machine. Mechanical failures and casualties occur. 7. The failure of the thresher shall be immediately stopped and repaired, and no sick operation shall be allowed. Repairs, adjustments, and troubleshooting must be performed after the thresher has been stopped.
