Automatic screening device

Abstract

The invention discloses an automatic screening device and relates to the technical field of machinery. The automatic screening device comprises a chassis, a bottom cover and a filter screen; the bottom of the chassis is connected with the bottom cover; the filter screen is placed inside the chassis; the middle of a fixed column is fixedly connected with a rotating shaft I; the right side of the rotating shaft I is fixedly connected with a conveying belt; the side, far away from the rotating shaft I, of the conveying belt is fixedly connected with a rotating shaft II; the left side of the rotating shaft II is fixedly connected with a motor; the rotating shaft II is driven to rotate by rotation of the motor to drive the conveying belt to move so that a material can be fed into the chassis along the conveying belt, thereby achieving the purpose of automatic feeding; a splint I is driven to rotate by following the rotation of the motor; a roller I and a roller II move leftwards and rightwards; a rolling wheel I on a splint IV moves back and forth on a clamping slot; a rolling wheel II behind the clamping groove can move up and down inside a sliding chute on the inner wall of a slidingdevice; therefore, the front end of the bottom cover can be continuously opened and closed with the rolling wheel; and thus the filtered material can be automatically discharged and collected.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to an automatic screening device. Background technique [0002] Corn is an annual monoecious cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop. It is also the crop with the highest total output in the world. Its planting area and total output are second only to rice and wheat. Corn has always been Both are known as longevity foods, rich in protein, fat, vitamins, trace elements, cellulose, etc., and have great potential for developing high-nutrition, high-biological function foods. Corn tastes sweet and can be used in various dishes, such as fried corn. , corn juice, etc. It is also the main raw material for industrial alcohol and shochu. After the corn is harvested, there are often stones, sand or broken corn in the corn, which affects the overall quality of the corn. Now people's life is getting better and better. There are m...

Problems solved by technology

[0003] In retail planting, after the corn is mature, the corn cobs are taken home and spread out for preliminary drying. During this process, the bag must be opened over and over again, and the corn kernels are poured out to dry in the ashram. After drying, the corn kernels are swept from the ground. Bagging again, so a lot of stones, soil particles and other impurities may be carried into the corn kernels during each bagging process, and it is necessary to carry out the screening and removal process again and again until the corn is 4-5% dry After drying, the corn kernels are packed in bags, placed in a ventilated and light place, dried in the sun and air-dried, and sold in the spring of the next year. In addition, corn kernels generally need two people to cooperate in bagging, one person supports the bag, and the other person packs the bag. If the quantity is larger, more people are required to cooperate, which greatly increases the labor cost. In addition, the bagging of corn kernels is basically realized by manual operation, which not only has low work efficiency, but also has high labor intensity and a high degree of automation. The production line is not matched, which urgently needs a new type of bagging machine with simple mechanism, less manual participation, high degree of automation, high stability, and low manufacturing cost to solve the current problem in order to improve work efficiency. Most of the bagging machines on the market The structure of the machine is simple, the function is single, and the degree of automation is not high. If integrated production is required, a variety of special equipment must be spliced ​​to form a production line. The improvement of production efficiency, based on the above, is in urgent need of a device that can do automatic feeding, automatic screening, automatic bagging and can be portable and mobile to meet people's needs in daily life
