Description

Rice cleaner

Technical field :

The utility model belongs to the technical field of grain milling pretreatment, and in particular relates to a rice impurity remover.

Background technology :

In the paddy, there are not only large impurities that are larger in volume and small impurities that are smaller than rice, such as stones, sand, and mud, but also light impurities that are smaller than rice, such as shriveled rice, chaff, rice straw, and leaf residue. The side-by-side mixes whose volume and specific gravity are almost equal to those of paddy rice can't be separated by common methods, such as winnowing and sieving. In addition, there are metal foreign objects in the rice, such as iron nails and small iron pieces. Impurities contained in rice, if not removed in time, will bring great harm to rice processing. During the processing of light impurities, it is easy to cause the blockage of the input pipeline and the feeding mechanism of the equipment, make the feeding uneven, and reduce the process effect and processing capacity of the equipment. Small impurities such as sediment and dust are likely to cause dust to fly during the process of feeding, lifting, and slide pipe transportation, polluting the environmental sanitation of the workshop, and endangering the physical and mental health of operators. Hard impurities such as stones and metal foreign objects are easy to damage the working surface and parts of mechanical equipment during processing, affect the process effect of the equipment, shorten the service life of the equipment, and even cause major equipment accidents. If impurities are not removed in time and mixed into the product, it will also reduce the purity of the product and affect the quality of finished rice and products.

Therefore, impurity removal is a very important link in the rice processing process. However, the removal of impurities in grains has always been a relatively big problem. For a long time, the laboratory has been using manual detection. Although it takes a lot of time and effort, the removal of impurities is relatively clean, the quality is good, and the detection results are relatively reliable, but the efficiency is low. very low. In production, a single impurity removal device is generally used for rice removal, and multiple combinations are combined into an assembly line. Although the efficiency is high, the quality of impurity removal is still not ideal.

Utility model content :

The purpose of the utility model is to overcome the above-mentioned existing problems and provide a rice cleaning machine with strong comprehensive performance, high efficiency and good quality.

In the rice remover of the utility model, after the motor is started, the rice to be removed is poured into the feeding device, and when passing through the feeding device, the metal foreign matter (such as small iron nails, small iron pieces, etc.) contained in the rice is removed A magnet attached to the magnet holder attracts and removes it from the rice. The rice with metal foreign matter removed enters the vibrating screening device, and the vibration is provided by the eccentric vibrating shaft. Rice is on the upper vibrating sieve of the vibrating screening device—the vibrating sieve plate with angled openings. The debris with a larger volume or area is pushed upwards from the large miscellaneous outlet into the large miscellaneous receiving bucket due to the parabolic motion of the sieve plate. Grains and impurities smaller than grains fall from the slots of the sieve plate into the lower sieve plate. The aperture of the lower sieve plate is small, allowing only impurities smaller than grains to leak down, and enter the small miscellaneous receiving hopper from the small miscellaneous outlet. The grains that have been screened and removed from the large and small impurities pass through the light-impurity wind separator, and the impurities (such as shriveled grains, empty shells, etc.) . The remaining grains and sideloads (such as wheat, mung beans, soybeans and pebbles, etc.) enter the sideloading device. The closed-loop grain-adhering conveyor belt of the side-by-side device is a fiber fabric that can adhere to grains (there are many micro-thorns on the surface of the rice), and the grains are hooked and entangled on the surface of the conveyor belt. , is "adhered" to the conveyor belt made of fiber fabric, and the grains are selected out. When the conveyor belt passes through the rice scraping device installed at the driven wheel, the grain scraper scrapes off the grains and collects them into the rice collection container. Just in. The remaining side-by-side objects open the side-by-side debris discharge door through the solenoid valve and enter into the side-by-side impurity collection box, and the whole cleaning process is completed.

The rice cleaning machine of the utility model has reasonable design, simple structure, convenient use and operation, strong comprehensive cleaning performance, higher efficiency than manual selection, and better cleaning quality than large combined cleaning machines.
