Description

Bean screening device for bean products Technical Field The invention belongs to the technical field of related equipment of soybean screening devices, and particularly relates to a soybean screening device used for producing high-quality soybean products. Background Bean products are various in variety, delicious and rich in nutritive value, and are popular with people. To produce high quality soy products such as soybean paste, soymilk, fermented soybeans, etc., it is important to optimize the production equipment and process, and to obtain high quality food materials. Soybeans are collected in autumn and stored until processed, and usually take several months or even years. During this period, some adverse factors such as temperature and humidity changes in the environment during transportation, local humidity in the storage environment and the like may cause mildew or worm damage to part of soybeans. Even a very small number of bad soybeans can seriously affect the quality of food, and particularly mildewed soybeans are extremely harmful to human health, so that the bad soybeans need to be selected and removed. There are many devices for screening soybeans in the prior art. For example, application publication number CN113663903A, named soybean screening device for soybean products, which mainly solves the problems of automatically and intermittently adding soybeans into the device and screening soybeans in multiple stages, is generally used for removing impurities such as larger soil and stones mixed into the soybeans, and another example is authorized publication number CN111804586B, named a black soybean screening machine with multiple screening functions before fermented soybean production, and the screening machine distinguishes the flat soybeans by air flow blowing and utilizes the principle that the flat soybeans are light in weight and can be blown up farther. However, because the volume of the soybeans is not obviously changed after mildewing or worm-eating, only the colors are greatly different, the device cannot screen out bad soybeans and needs to rely on manual selection. If mildew or worm damage is in the early stage, the color and luster are difficult to distinguish. In fact, it is known that dried and intact soybeans have a high hardness, while mildewed or worm-eaten soybeans, even in the early stages, have a greatly changed internal structure and a greatly reduced hardness. Using this natural phenomenon, our skilled person has found a simple and easy solution. Disclosure of Invention Aiming at the defects in the prior art, the invention aims to provide the soybean screening device for the bean products, which can screen and remove soybeans which are mildewed or damaged by worms. The soybean screening device for soybean products is characterized in that the soybean screening device is used for carrying out grinding on soybeans with certain strength, so that the soybeans which are mildewed or damaged by worms are broken into two parts, then broken soybeans are screened out, the soybean screening device comprises a platform for mounting various components and mechanisms, a lifting mechanism which can be lifted and is used for containing the soybeans to be screened, a lifting mechanism which can be stably arranged on the platform and is used for lifting and descending the lifting bucket, a gate arranged at the lower outlet of the lifting bucket, a quantitative conveying mechanism which is arranged on the platform and is arranged below the gate, a negative pressure suction component which is arranged at the output end of the quantitative conveying mechanism and is used for sucking the soybeans conveyed in the quantitative conveying mechanism, a grinding separation bin which is arranged below the negative pressure suction component and is fixedly connected with the negative pressure suction component, a grinding component which is arranged in the grinding separation bin, and a supporting frame which is arranged below the grinding component, is arranged on the platform and is fixedly connected with the grinding separation bin; the quantitative conveying mechanism is in crawler circulating transmission, a plurality of conveying boxes are fixedly arranged on the crawler at intervals, the crawler runs, one conveying box runs below the gate, the crawler stops, the gate is opened, soybeans successively enter the conveying boxes until reaching a design component, the gate is closed, the crawler runs to continuously contain the next conveying box, the suction inlet of the negative pressure suction assembly has a telescopic function, when the conveying boxes containing the soybeans run below the suction inlet, the suction inlet is downwards detected to be identical with the conveying boxes containing the soybeans, the negative pressure suction assembly sucks all the soybeans into the rolling separation bin, the rolling assembly rolls the soybeans after tiling, and finally the rolled soybeans fall into
