[0025] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following is combined with specific embodiments and drawings, and the utility model is further described in detail. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0026] As Figures 1-4 shown, a wheat seed resource stress resistance treatment equipment, including cold plasma seed treatment machine 1, cold plasma seed treatment machine 1 inside is equipped with belt conveyor 2, the upper and lower sides of the belt of belt conveyor 2 are provided with pole plate 3, the feeding end of cold plasma seed treatment machine 1 is connected with vacuum hopper 4, star feeder 5, the feeding end of vacuum hopper 4 is connected with temporary storage hopper 7 through plug-in valve 6, the discharge end flange of cold plasma seed treatment machine 1 is connected with lock gas unloader 8, the insulating shell of pole plate 3 is fixed with material blocking plate 9, cold plasma seed treatment machine 1, vacuum hopper 4, lock gas unloader 8 are communicated with vacuum valve 10, vacuum valve 10 is connected with vacuum pump 12 through pipeline 11 in parallel. In the feeding process, the seeds in temporary storage hopper 7 always maintain a certain material level, therefore, when vacuum hopper 4 is extracted negative pressure, due to the blocking effect of the seeds in temporary storage hopper 7, the negative pressure in vacuum hopper 4 is not influenced too much, and the power consumption of vacuum pump 12 is not increased too much.

[0027] The discharge end of the vacuum hopper 4 is tapered, and a baffle 13 is welded inside the feed end of the vacuum hopper 4.

[0028] The baffle 13 and the inner wall of the vacuum hopper 4 form a cavity which is closed at the top and sides and open at the bottom, and the communication between the vacuum valve 10 and the vacuum hopper 4 is located on the vacuum hopper 4 at the cavity. When controlling the material level, the material level should not be too high, preferably below the lower end of the baffle 13, so that the seeds will not be mistakenly sucked away when the negative pressure is drawn.

[0029] The communication between the vacuum valve 10 and the air-locked unloader 8 is located at the middle of the side of the air-locked unloader 8. After the belt conveyor 2 transports the wheat seeds to the discharge end, the air-locked unloader 8 is discharged, the discharge wheel in the air-locked unloader 8 is star-shaped, and during rotation, the wheat seeds are pushed to the discharge end and released after pressure balance at the discharge end, and then the negative pressure is released, the discharge wheel continues to rotate to the vacuum valve 10, and the negative pressure is drawn by the vacuum pump 12, and the discharge wheel continues to rotate to the feed end of the air-locked unloader 8, and since it has been drawn to negative pressure, the pressure inside the cold plasma seed treatment machine 1 is the same, and the wheat seeds smoothly enter the discharge wheel, thereby continuing to discharge.

[0030] The width of the belt of the belt conveyor 2 is greater than the width of the plate 3, and the material blocking plate 9 has four, which are respectively located on both sides of the insulating shell of the two plates 3. When the wheat seeds roll to both sides of the belt conveyor 2, the material blocking plate 9 can block, even if there are small wheat seeds rolling from the gap between the material blocking plate 9 and the belt, since the width of the belt is greater than the width of the plate 3, and the material blocking plate 9 below the belt blocks, the wheat seeds will not enter the plate 3 below the belt.

[0031] The material blocking plate 9 is a rubber plate.

[0032] The star-shaped feeder 5 is located above the feed end of the belt conveyor 2 inside the cold plasma seed treatment machine 1, and the feed end of the star-shaped feeder 5 penetrates the shell of the cold plasma seed treatment machine 1 and communicates with the vacuum hopper 4.

[0033] The vacuum hopper 4 and the temporary storage hopper 7 are both provided with observation windows 14, and the vacuum hopper 4 and the temporary storage hopper 7 are both hoppers with internal material level meters.

[0034] The working principle of the utility model is:

[0035] Before use, the wheat seeds are transported from the previous process of the assembly line to the temporary storage hopper 7, the plug valve 6 is opened, the wheat seeds fall into the vacuum hopper 4, when the material level in the vacuum hopper 4 reaches the set value, the plug valve 6 is closed, when the material level in the temporary storage hopper 7 reaches the set value, the vacuum pump 12 and the vacuum valve 10 are opened, the cold plasma seed treatment machine 1, the vacuum hopper 4 and the air-locked unloader 8 are drawn to the set vacuum degree, thereby completing the preparation work before use.

[0036] When the wheat seeds are continuously processed, the wheat seeds are transported from the previous process of the flow line to the temporary hopper 7, the flashboard valve 6 is opened, and the opening degree of the flashboard valve 6 is adjusted so that the wheat seeds fall to the vacuum hopper 4 at a certain speed, and the star feeder 5 and the belt conveyor 2 are opened at the same time, so that the wheat seeds fall from the vacuum hopper 4 to the belt conveyor 2 at the same speed. During the feeding process, the seeds in the temporary hopper 7 always maintain a certain material level, so when the negative pressure is drawn in the vacuum hopper 4, the negative pressure in the vacuum hopper 4 will not be greatly affected due to the blocking effect of the seeds in the temporary hopper 7, and the power consumption of the vacuum pump 12 will not be greatly increased. A cavity is formed between the baffle 13 and the inner wall of the vacuum hopper 4, and the material level is controlled so as not to be too high, preferably below the lower end of the baffle 13, so that the seeds are not mistakenly drawn away during the negative pressure drawing.

[0037] The star feeder 5 has a material distribution function, so that the wheat seeds are evenly and flatly laid on the belt conveyor 2. The two sides of the polar plate 3 are provided with material blocking plates 9, which can block the wheat seeds when the wheat seeds roll to the two sides of the belt conveyor 2. Even if the wheat seeds roll from the gap between the material blocking plate 9 and the belt, the wheat seeds will not enter the polar plate 3 below the belt due to the width of the belt being greater than the width of the polar plate 3 and the blocking of the material blocking plate 9 below the belt.

[0038] The belt conveyor 2 transports the wheat seeds to the discharge end and discharges from the air-locked discharger 8. The discharge wheel in the air-locked discharger 8 is in a star shape, and during rotation, the wheat seeds are pushed to the discharge end and discharged after pressure balance and release of negative pressure at the discharge end. The discharge wheel continues to rotate to the vacuum valve 10 position, and negative pressure is drawn by the vacuum pump 12. The discharge wheel continues to rotate to the feeding end of the air-locked discharger 8, and since it has been drawn to negative pressure, the pressure inside the cold plasma seed processing machine 1 is the same, so the wheat seeds smoothly enter the discharge wheel, thereby continuing to discharge.

[0039] The above-described embodiments are only used to describe the preferred embodiments of the present application, and are not used to limit the design concept and scope of the present application. Various modifications and improvements to the technical solutions of the present application made by those skilled in the art without departing from the design concept of the present application shall fall within the protection scope of the present application.
