This is a traditional grain extractor, which is used to take grains out of the granary； this extractor can not only extract grains, but also make grains lose weight at the same time, so that trucks can leave the already heavy fields. Therefore, on the extractor tube, which is responsible for transporting the cereal from the jar to the truck or the container of torva, whether one part, or two or more parts, are fixed, or can be divided between these parts by means of hinge or other connection, which is a developed gift, Changing the use of componentsTherefore, the workflow was changed to obtain the weight of the grain being extracted； then an extractor with two working stages was designed, the first stage was to collect the grain, the second stage was to fill up the grain, the second stage was to reload the grain and lift the grain onto the truck. Tolva, in this way, the tube is divided into two completely different parts, stage a, cereal collection and transportation of heavy objects, stage B,Push the cereal onto a truck or a torva The component of this document is the component that contains phase a, the task of which is to collect grains from the catheter. There is a grain lifting device with a corresponding motion command system inside, and there are phase B components, i.e. multiple weighing units, which constitute the constraints related to phase a, in order to transmit information to the balance of payments for demonstration,The cereal lifting device and its corresponding motion command system are the last part to control the cereal from Class A to class B. in class B control, the cereal lifting device must allow the cereal to pass or discharge temporarily, so that the cereal has a momentary weight, At another time, we can pour grains into torva or truck boxes.Destinada a sustituir a las extractoras convencionales de granos, empleadas para sacar el cereal de adentro de un silo bolsa； este tipo de extractora, permite a la vez de generar la extracción, poder pes
