The variety show of "Aspire to Life" is not unfamiliar to everyone. One of the links makes me remember that the ingredients must be exchanged with corn kernels. At that time, corn threshers became their " magic weapon . " I thought that in the past, all the corn was manually peeled off. If the corn is not much, it will be in a " semi-disabled " state even if the hand is " not disabled " . However, with the application and popularization of the thresher, not only is the operation simple, but also greatly improves people's work efficiency and reduces the work intensity. The author has learned that the thresher is a harvesting machine, which refers to a machine that can separate crop grains from stems, mainly refers to the harvesting machinery of grain crops. The type of thresher differs depending on the crop. For example, rice threshing generally uses a " rice machine " ; corn threshing uses a " corn thresher " and the like. The emergence of threshing machinery has greatly reduced the labor intensity of grain harvesting and also improved agricultural productivity. We know that in the past, we used handcuffs and used some simple tools. With the continuous expansion of the planting area of rice crops ( rice, corn, green beans ) and the continuous increase in production, the thresher was officially invented in this case, but at that time it was hand-fed ( corn cob ) , which was inefficient and Can core, granulated is not clean. With the advancement of agricultural modernization, the threshing machine is also developing continuously. From the original small and medium-sized development to the current large-scale, from the original single-tube development to the current double-tube, from the original manual feeding and semi-automatic feeding to the The current automatic feeding has grown from the original tens of kilograms per hour to the current 30 tons per hour . Compared with the traditional threshing method, mechanized threshing is favored by the market for its many advantages. According to the professional introduction, the basic mechanism of the thresher generally includes the transmission line, the continuously variable transmission, the second-speed shifting, the triangular pulley on the motor, the unique cutter, the cutter head, and the feeding and feeding device. The motor rotates clockwise to feed material, and the counterclockwise steering is mainly used to push out corn cobs, rice husks, green bean shells, etc., and the fans are used to blow off the chips and slag generated during threshing. The author has learned that a threshing machine designed for the design of a fully enclosed reverse-rotating rolling screen has appeared on the market. The mechanical grain separation effect is good, and the occurrence of grain entrainment in the crop core can be minimized. In addition, this type of machinery is also equipped with a screw feeding hopper for forklift feeding and a feeding mechanism for chain-type automatic feeding trough, which is convenient for farmers to feed crops, and the feeding amount is large, rapid and efficient, and Reliable performance. However, it is worth noting that although the thresher is simple and easy to operate as a whole, it does not rule out a safety accident caused by misoperation or unfamiliarity. Therefore, the majority of users need to pay attention to some problems before using. First, don't overload work. No matter whether it is powered by electric motor or diesel engine, it can't be overloaded during work, otherwise it is very unsafe. Second, the safety device is not complete. The safety device on the thresher and its power machine must be complete. For example, the transmission belt must have a safety shield, and the motor must be grounded to ensure personal safety. Third, the feeding is uneven. Should be evenly fed, the amount of feed is appropriate, such as rice and wheat threshing, can not be fed into the bundle, not to mix the foreign matter with the straw, not only damage to the machine parts, but also a certain safety Hidden dangers. More importantly, the human arm must not reach into the feeding port to prevent it from being injured by the high-speed rotating rod or even interrupting the arm. Fourth, do not move and install at will. Generally, the installation of the thresher must be performed by skilled professional technicians. Do not do it yourself. Experts suggest that if you want to move the machine, you must first turn off the power, the insulated wire can not be pulled on the ground to prevent the insulation layer from being worn, causing leakage and injury. The shutdown and start-up of the diesel engine should be checked by the professional and then operated. Fifth, avoid using homemade and eliminated threshers. In order to save costs, some people make homemade threshers or use old de-granulators that are eliminated. Compared with the thresher produced by regular manufacturers, such threshers have poor safety performance and cannot be used. Finally, before using the equipment, the thresher should be carefully inspected and repaired to see if the bolts are loose, the rods are intact, and the transmission parts are defective. Identify safety hazards and promptly be eliminated, must not bring the "disease" operation.
