Description

Technical Field

[0001] The utility model relates to the technical field of impurity screening, in particular to a screening machine for a grain impurity intelligent tester. Background Technique

[0002] Grain impurity screening refers to the process of screening and separating impurities in grains during grain processing to improve the quality and purity of grains. Grain impurities mainly include stones, metals, straws, soil clods, etc. Existing technologies include physical screening methods, gravity separation methods, and optical sorting methods. In addition, manual screening methods can also be used, which are only applicable to small-scale production lines or situations with high requirements for screening effects. Grain impurity screening is an indispensable link in grain processing. Through physical screening, gravity separation, optical sorting and other methods, impurities in grains can be effectively separated, the quality and purity of grains can be improved, and basic data for subsequent processing and quality control can also be provided.

[0003] The utility model of the authorized announcement number CN210098198U discloses a soybean impurity screening device. The utility model makes the sieve body vibrate regularly, and utilizes the different rolling speeds of soybeans and impurities on the sieve plate, so that the impurity screening device can effectively separate soybeans and impurities, and is convenient for processing the separated soybeans.

[0004] The above device can achieve the purpose of separating grains and impurities, but only relying on the different rolling speeds of soybeans and impurities on the sieve plate for screening, there will still be impurities that cannot be removed in time, resulting in insufficient separation of impurities and grains. Therefore, a device that can separate impurities and grains more fully is needed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a screening machine for a grain impurity intelligent tester to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An intelligent screening machine for grain impurities, comprising a box body, a impurity hopper is arranged below the box body, an air separator is arranged on the left side of the box body, and the lower end of the air separator penetrates through the side wall of the box body and extends into the box body. A partition is arranged inside the air separator, an impurity discharge port is arranged above the right side of the partition, an inner sieve barrel is arranged at the top inside the box body, ear pieces are oppositely arranged above the right side of the inner sieve barrel, a second fixing seat is arranged between the ear pieces and is fixedly connected with the inner sieve barrel, a vibrator is arranged above the second fixing seat, a movable shaft is rotatably installed through the upper part of the ear piece and the second fixing seat, a first fixing seat is fixedly arranged at the bottom of the right side of the box body, a cylinder is installed on the first fixing seat through a rotating shaft, and the end of the telescopic part of the cylinder is connected with the lower part of the ear piece through a rotating shaft. A grain hopper is arranged on the left side of the inner sieve barrel, and the grain hopper penetrates through the side wall of the box body and the inner sieve barrel and extends into the inner sieve barrel. An opening is arranged at the connection between the grain hopper and the inner sieve barrel.

[0008] As a further scheme of the present utility model: inner baffles are oppositely arranged at the top inside the air separator.

[0009] As a further scheme of the present utility model: the mesh holes on the inner sieve barrel are only distributed on the right side of the grain hopper.

[0010] As a further scheme of the present utility model: an outer sieve barrel is arranged below the inner sieve barrel, and the grain hopper penetrates through the outer sieve barrel and an opening is arranged at the connection between the grain hopper and the outer sieve barrel.

[0011] As a further scheme of the present utility model: the inner sieve barrel and the outer sieve barrel are made of metal materials.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The inner baffle is used to centrally feed the grains into the air separator. The air separator conducts a primary screening on the grains. The heavier grains naturally discharge from the lower discharge port of the air separator, and the lighter impurities are discharged outwards from the impurity discharge port on the right side of the partition under the action of the wind force in the air separator, thereby completing the preliminary screening of the grains and impurities and improving the screening efficiency.

[0014] 2. Through the cooperation of the vibrator and the second fixing seat, with the vibrator as the vibration source, the inner sieve barrel and the outer sieve barrel are vibrated. The grains after the primary screening are subjected to a secondary screening in the inner sieve barrel. The impurities and smaller grains fall into the outer sieve barrel, and the outer sieve barrel conducts a further screening on the grains after the secondary screening. The impurities fall into the impurity hopper and are then discharged outwards, achieving the purpose of purifying the grains. At the same time, after the screening is completed, the cylinder makes the ear piece move around the movable shaft, thereby tilting the inner sieve barrel and the outer sieve barrel, and the grains are discharged outwards from the grain hopper, saving a large amount of labor and improving the efficiency of screening the grains.

[0020] Embodiment

[0021] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, a screening machine for intelligent inspection of grain impurities includes a box body 1, an impurity hopper 3 is arranged below the box body 1, a winnower 9 is arranged on the left side of the box body 1, and the lower end of the winnower 9 penetrates through the side wall of the box body 1 and extends into the box body 1. Inner baffles 11 are oppositely arranged at the top inside the winnower 9. A partition board 12 is arranged on the right side of the inner baffle 11 and is fixedly connected to the inner wall of the winnower 9. An impurity discharge port 10 is arranged above the right side of the partition board 12. The grains are concentrated and fed into the winnower 9 through the inner baffle 11. After the winnower 9 conducts primary screening on the grains, the heavier grains naturally discharge from the lower discharge port of the winnower 9, and the lighter impurities are discharged outwards from the impurity discharge port 10 on the right side of the partition board 12 under the action of the wind force in the winnower 9, thereby completing the preliminary screening of grains and impurities and improving the screening efficiency.

[0022] On the inner top of the box body 1, an inner sieve barrel 14 is provided. Above the right side of the inner sieve barrel 14, lugs 6 are oppositely arranged. Between the lugs 6, a second fixing seat 13 is arranged and the second fixing seat 13 is fixedly connected with the inner sieve barrel 14. Above the second fixing seat 13, a vibrator 8 is provided. An activity shaft 7 is rotatably installed through the upper part of the lugs 6 and the second fixing seat 13. At the bottom right of the box body 1, a first fixing seat 4 is fixedly arranged. On the first fixing seat 4, a cylinder 5 is installed through a rotating shaft. The end of the telescopic part of the cylinder 5 is connected with the lower part of the lugs 6 through a rotating shaft. Below the inner sieve barrel 14, an outer sieve barrel 15 is provided. On the left side of the outer sieve barrel 15, a grain hopper 2 is provided and the grain hopper 2 penetrates through the side wall of the box body 1, the outer sieve barrel 15 and the inner sieve barrel 14 and extends into the inner sieve barrel 14. At the connection of the grain hopper 2 with the outer sieve barrel 15 and the inner sieve barrel 14, an opening is provided. Through the cooperation of the vibrator 8 and the second fixing seat 13, with the vibrator 8 as the vibration source, the inner sieve barrel 14 and the outer sieve barrel 15 can vibrate. The preliminarily screened grains are subjected to secondary screening in the inner sieve barrel 14. The impurities and smaller grains fall into the outer sieve barrel 15. The outer sieve barrel 15 screens the grains after secondary screening again. The impurities fall into the impurity hopper 3 and are then discharged externally, achieving the purpose of purifying the grains. At the same time, after the screening is completed, the cylinder 5 makes the lugs 6 move around the activity shaft 7, and then makes the inner sieve barrel 14 and the outer sieve barrel 15 tilt, and the grains are discharged externally from the grain hopper 2, saving a large amount of labor and improving the efficiency of grain screening.

[0023] When the device is running, start the vibrator 8 and the air separator 9. The untreated grains are fed downward from the inner baffle 11. Under the action of the wind force in the air separator 9, the impurities are discharged externally from the impurity discharge port 10 on the right side of the partition plate 12. The heavier grains are discharged into the middle of the inner sieve barrel 14 through the discharge port of the air separator 9. Under the vibration of the vibrator 8, the impurities and smaller grains fall into the outer sieve barrel 15 and are screened again. Then the impurities are directly discharged externally through the impurity hopper 3. After the vibration is completed, turn off the vibrator 8 and the air separator 9, start the cylinder 5, and the lugs 6 move around the activity shaft 7, making the inner sieve barrel 14 and the outer sieve barrel 15 tilt, and the grains are discharged externally from the grain hopper 2, thus completing the purpose of screening grains and impurities.
