[0002] After grain is harvested, impurities mixed in the grain are removed by screening, which is convenient for the storage or processing of the grain. In the existing grain screening equipment, impurities in the grain are often removed through a sieve mesh.
[0003] After the existing grain production, there will be more lighter impurities in the grain. The existing sorting machine cannot ensure the uniform rolling and winnowing of the grain, resulting in incomplete screening of the lighter impurities during grain winnowing. There will still be a small amount of light impurities in the grain, affecting the quality of the grain. Summary of the Utility Model
[0004] The main purpose of the utility model is to provide a winnowing machine for grain production, which can effectively solve the technical problem that the screening of lighter impurities in the background art is incomplete, and there will still be a small amount of light impurities in the grain, affecting the quality of the grain.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A winnowing machine for grain production includes a bracket, and a winnowing cylinder is fixedly installed at the upper end of the bracket. One side of the upper end of the winnowing cylinder is provided with a feeding hopper, and a feeding pipe is installed at the lower end of the feeding hopper. The feeding pipe enters one side inside the winnowing cylinder. A rolling structure is arranged inside the winnowing cylinder. The rolling structure includes two groups of rolling plates. At the front and rear ends of both sides of the lower ends of the two groups of rolling plates, placing seats are fixedly arranged. A blower is installed on one side between the two groups of rolling plates, and the front and rear ends of the blower are fixedly connected to the inner wall of the winnowing cylinder.
[0007] As a further scheme of the utility model, a disassembly structure is installed between the rolling plate and the placing seat. The disassembly structure includes vertical plates fixedly arranged at the front and rear ends of both sides of the rolling plate. A groove is opened at the upper end of the placing seat located at the lower end of the vertical plate. A screw rod is threadedly arranged inside the placing seat, and the output end of the screw rod passes through the vertical plate and enters the inside of the placing seat.
[0008] As a further scheme of the utility model, protruding plates are installed at the front and rear ends of the upper ends of the two groups of rolling plates.
[0009] As a further scheme of the utility model, a threaded cap is threadedly arranged on the outer wall of one side of the winnowing cylinder, and a non-woven fabric bag is fixedly arranged on one side of the threaded cap.
[0010] As a further scheme of the utility model, a fixed frame is fixedly arranged on the inner wall of the bracket, and a drawer box is arranged inside the fixed frame.
[0011] As a further solution of the present utility model, a control valve is fixedly arranged at the front end of the blanking pipe.
[0012] The beneficial effects of the present utility model are as follows:
[0013] By arranging the roller structure, the grains are rolled onto the upper ends of the two sets of rolling plates, increasing the falling route of the grains. At the same time, with the blowing of the fan, the light impurities in the grains can be better blown out from one side of the air separation cylinder, and the air separation of the grains can be better carried out;

Specific Embodiments
[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.
[0021] Such as Figures 1-4As shown in the figure, a winnowing machine for grain production includes a bracket 1. At the upper end of the bracket 1, a winnowing cylinder 2 is fixedly installed. On one side of the upper end of the winnowing cylinder 2, a feeding hopper 3 is installed. At the lower end of the feeding hopper 3, a feeding pipe 4 is installed. The feeding pipe 4 enters one side inside the winnowing cylinder 2. A rolling structure 6 is arranged inside the winnowing cylinder 2. The rolling structure 6 includes two groups of rolling plates 7. At the front and rear ends on both sides of the lower ends of the two groups of rolling plates 7, placing seats 8 are fixedly arranged. On one side between the two groups of rolling plates 7, a fan 5 is installed. The front and rear ends of the fan 5 are fixedly connected to the inner wall of the winnowing cylinder 2.
[0022] In this embodiment, a splitting structure 9 is installed between the rolling plate 7 and the placing seat 8. The splitting structure 9 includes vertical plates 10 fixedly arranged at the front and rear ends on both sides of the rolling plate 7. At the upper end of the placing seat 8 located at the lower end of the vertical plate 10, a groove 11 is opened. A screw rod 12 is threadedly arranged inside the placing seat 8. The output end of the screw rod 12 passes through the vertical plate 10 and enters the inside of the placing seat 8.
[0023] The vertical plate 10 enters the groove 11 at the upper end of the placing seat 8 to realize the placement of the rolling plate 7 and the placing seat 8. The screw rod 12 passes through the placing seat 8 and then through the vertical plate 10, which can realize the fastening installation of the rolling plate 7.
[0024] In this embodiment, protruding plates are installed at the front and rear ends of the upper ends of the two groups of rolling plates 7.
[0025] The protruding plates can limit the rolling grains to prevent the grains from falling from both sides of the rolling plate 7.
[0026] In this embodiment, a threaded cap 13 is threadedly arranged on the outer wall of one side of the winnowing cylinder 2. On one side of the threaded cap 13, a non-woven fabric bag 14 is fixedly arranged.
[0027] The threaded cap 13 is used for threaded installation with the winnowing cylinder 2 and is also used to set the non-woven fabric bag 14 for collecting light impurities.
[0028] In this embodiment, a fixed frame 15 is fixedly arranged on the inner wall of the bracket 1. Inside the fixed frame 15, a drawer box 16 is arranged.
[0029] The fixed frame 15 is used to set the fixed frame 15, and the fixed frame 15 is used to collect the grains screened on one side of the winnowing cylinder 2.
[0030] In this embodiment, a control valve 17 is fixedly arranged at the front end of the feeding pipe 4.
[0031] The control valve 17 is used to control the closing inside the feeding pipe 4.
[0032] It should be noted that the present utility model is a winnowing machine for grain production. When winnowing the grain to remove the lighter impurities in the grain, the control valve 17 is opened, and the grain is poured into the inside of the feed hopper 3. The grain falls onto the upper end of the rolling plate 7. The grain rolls to one side. At the same time, the blower 5 is started, so that the air source blows from the lower end of the upper rolling plate 7, and the light impurities in the grain are blown to one side of the winnowing cylinder 2. When the grain falls onto the lower rolling plate 7, the overall falling route of the grain is increased. At the same time, the grain on the upper end of the lower rolling plate 7 can be winnowed for the second time, which can improve the winnowing effect.
[0033] When winnowing the grain with smaller particles is required, the screw 12 is rotated, so that the screw 12 is taken out from the inside of the placing seat 8. After taking it out, the threaded cap 13 is removed, and the rolling plate 7 is pulled to take out and replace the rolling plate 7, which can be adapted to the winnowing of grains with different particle sizes.
[0034] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
