[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] See also Figure 1-6 The present invention provides a technical solution: a drug soaking device for wheat breeding, comprising a soaking barrel 1 and a first piston cylinder 2 fixedly connected to the left side of the soaking barrel 1, an observation window 42 is provided on the front of the soaking barrel 1, and the soaking situation of the wheat seeds inside the soaking barrel 1 can be observed through the observation window 42, and the outer surface of the liquid outlet pipe 39 fixedly connected to the lower part of the back of the soaking barrel 1 is provided with a valve 40. The arrangement of the liquid outlet pipe 39 and the valve 40 facilitates the discharge of the medicinal liquid and wheat seeds inside the soaking barrel 1, and an electric telescopic rod 18 is fixedly connected to the upper surface of the first piston cylinder 2, and the output end of the electric telescopic rod 18 is fixedly connected to the piston bottom plate 19 that is slidably connected to the inside of the first piston cylinder 2, and the electric telescopic rod 18 is slidably connected to the through-point of the first piston cylinder 2, and a group of first check valves 20 are fixedly connected to the lower part of the left side of the first piston cylinder 2. The operation of the electric telescopic rod 18 can drive the piston bottom plate 19 to move up and down on the inner wall of the first piston cylinder 2.

[0034] The bottom surface of the soaking barrel 1 is provided with a first cavity 3, a second cavity 4 and a third cavity 7. The first cavity 3 is connected to the second cavity 4 through the first solenoid valve 5, and the first piston cylinder 2 is connected to the interior of the first cavity 3 through the first one-way valve 6. The lower part of the left side of the first piston cylinder 2 is fixedly connected with a groove plate 21, and the inner wall of the groove plate 21 is clamped with a filter screen 22. The air inlet end of the first check valve 20 is connected to the interior of the groove plate 21, and the air outlet end of the first check valve 20 and the air inlet end of the first one-way valve 6 are both connected to the interior of the first piston cylinder 2, and the air outlet end of the first one-way valve 6 is connected to the interior of the first cavity 3, ensuring that the first piston cylinder 2. The flow direction of the internal air, that is, when the electric telescopic rod 18 drives the piston bottom plate 19 to move up and down on the inner wall of the first piston cylinder 2, the external air flows into the first cavity 3 through the filter screen 22, the groove plate 21, the first check valve 20, the first piston cylinder 2 and the first one-way valve 6, and flows into the interior of the soaking barrel 1 through the first cavity 3, the second cavity 4, the second one-way valve 10, the third cavity 7 and the through hole 8. The bubbles formed clean the wheat seeds soaked in the soaking barrel 1, so that the outer surface of the wheat seeds is soaked more evenly, thereby increasing the soaking effect of the wheat seeds and reducing the damage to the wheat seed skin caused by mechanical stirring.

[0035] When the second solenoid valve 17 is closed and the first solenoid valve 5 is opened, the operation of the first piston cylinder 2 drives the piston base plate 19 to move up and down on the inner wall of the electric telescopic rod 18, and the external air enters the interior of the first piston cylinder 2 through the filtration of the filter screen 22. The air inside the first piston cylinder 2 enters the interior of the first cavity 3 and the second cavity 4 through the first one-way valve 6. Then the air inside the first cavity 3 and the second cavity 4 flows into the medicine liquid inside the soaking barrel 1 through the second one-way valve 10, the third cavity 7 and the through hole 8. The bubbles generated on the bottom wall of the soaking barrel 1 move upward, which has a stirring effect on the wheat seeds soaked in the soaking barrel 1, making the wheat seeds soaked more fully and reducing the damage to the seed epidermis caused by mechanical stirring.

[0036] A group of through holes 8 communicating with the interior of the third cavity 7 are provided on the inner bottom wall of the soaking bucket 1, a group of rubber rings 9 fixedly connected to the inner bottom wall of the third cavity 7 are fixedly connected to the inner top wall of the third cavity 7, and a group of second one-way valves 10 fixedly connected to the inner bottom wall of the third cavity 7 are both connected to the interiors of the first cavity 3 and the second cavity 4. A groove 35 communicating with the third cavity 7 is provided on the lower right side of the soaking bucket 1, and a rubber ring 36 is fixedly connected to the inner wall of the groove 35, so that the internal air pressure of the enclosed space formed by the groove 35 and the rubber ring 36 is equal to that of the third cavity 7. The internal air pressure of the cavity 7 is the same, and the rubber ring 36 and the rubber ring 9 have the same characteristics and specifications, so that when the internal air pressure of the groove 35 and the third cavity 7 changes, the rubber ring 36 and the rubber ring 9 expand to the same size, which is conducive to the user judging the expansion size of the rubber ring 9 inside the soaking bucket 1 by observing the rubber ring 36 outside the soaking bucket 1. The through hole 8, the rubber ring 9 and the second one-way valve 10 are on the same vertical line, ensuring that the air at the outlet end of the second one-way valve 10 can flow into the interior of the soaking bucket 1 through the rubber ring 9 and the through hole 8. The right side of the soaking bucket 1 is fixed The connected second piston cylinder 11 is connected to the interior of the third cavity 7, and the inner wall of the second piston cylinder 11 is slidably connected to the piston plate 12, and the threaded rod 13 threadedly connected to the right side of the second piston cylinder 11 is rotatably connected to the right side of the piston plate 12. The threaded rod 13 can be rotated to drive the piston plate 12 to move leftward on the inner wall of the second piston cylinder 11, so that the air inside the second piston cylinder 11 flows into the interior of the third cavity 7, thereby increasing the air pressure inside the third cavity 7 and causing the rubber ring 9 to expand toward the through hole 8, so that the air outlet hole connected to the through hole 8 and the second one-way valve 10 is smaller, and the size of the air outlet hole of the device is adjusted, thereby adjusting the size of the bubbles generated by the device. The bubble size directly affects its rising speed and distribution range in the liquid. Smaller bubbles rise slower and can stay in the liquid longer, thereby more fully contacting the wheat seeds. Larger bubbles rise faster, but have a greater impact on the seeds. By adjusting the bubble size, the distribution of bubbles in the liquid can be optimized, so that the bubbles stir the wheat seeds more evenly, thereby improving the stirring effect of the bubbles on the wheat seeds.

[0037] The interior of the fence frame 14 arranged on the upper part of the soaking barrel 1 is provided with a connected first cavity 15, and a second cavity 37 is provided on the left side of the interior of the fence frame 14. A group of oscillation motors 38 are fixedly connected to the inner bottom wall of the second cavity 37. The setting of the oscillation motor 38 enables the fence frame 14 to contact the surface of the liquid medicine inside the soaking barrel 1. The wheat seeds floating on the surface of the liquid medicine due to accumulation can be driven by the vibration of the oscillation motor 38 to be better broken up and sink into the liquid medicine. The inner bottom wall of each first cavity 15 is fixedly connected with a group of third one-way valves 16, and the first cavity 15 is connected to the interior of the first piston cylinder 2 through the second solenoid valve 17. A telescopic tube 41 is provided at the fixed connection between the second solenoid valve 17 and the first cavity 15. The air inlet end of the third one-way valve 16 is connected to the interior of the first cavity 15, and The air outlet end of the third one-way valve 16 is connected to the outside. The setting of the third one-way valve 16 ensures the flow direction of the air inside the first cavity 15. When the second solenoid valve 17 is opened and the first solenoid valve 5 is closed, on the one hand, the air inside the first piston cylinder 2 flows to the inside of the soaking barrel 1 through the first one-way valve 6, the first cavity 3, the third cavity 7 and the through hole 8. On the other hand, the air inside the first piston cylinder 2 flows to the inside of the soaking barrel 1 through the second solenoid valve 17, the telescopic tube 41, the first cavity 15 and the third one-way valve 16, forming bubbles in the medicinal liquid inside the soaking barrel 1 with the left side bubbles facing upward and the right side bubbles facing downward and then upward. Changing the direction of the generated bubbles is beneficial to the bubbles inside the soaking barrel 1 to form a tumbling effect on the wheat seeds soaked in the medicinal liquid, which is more conducive to the sufficient stirring and soaking of the wheat seeds in the medicinal liquid.

[0038] The inner walls of a group of circular grooves 23 opened on the upper surface of the soaking barrel 1 are fixedly connected to the motor 24, and the output end of each motor 24 is fixedly connected to the reciprocating screw 25. The outer surface of each reciprocating screw 25 is threadedly connected to a slider 26, and the slider 26 is slidably connected to the inner wall of the circular groove 23 to prevent the slider 26 from rubbing against the inner wall of the circular groove 23 when the slider 26 moves back and forth on the outer surface of the reciprocating screw 25. The U-shaped tube 27 fixedly connected to the upper surface of each slider 26 is fixedly connected to the upper surface of the fence frame 14. When the motor 24 is working, it can drive the reciprocating screw 25 to rotate, so that the slider 26 moves back and forth up and down on the outer surface of the reciprocating screw 25, and then the U-shaped tube 27 drives the fence frame 14 to move back and forth up and down, so that the fence frame 14 contacts the water surface of the medicine liquid inside the soaking barrel 1, and also allows the fence frame 14 to submerge into the medicine liquid in the soaking barrel 1.

[0039] The inner wall of the circular groove 23 is fixedly connected with an annular piston cylinder 28, and the inner wall of the annular piston cylinder 28 is slidably connected with an annular piston plate 29. A pair of straight rods 30 are fixedly connected to the upper surface of the annular piston plate 29. The straight rods 30 extend into the interior of the circular groove 23 and are fixedly connected to a retaining ring 31 provided inside the circular groove 23. The straight rods 30 are slidably connected to the penetration of the annular piston cylinder 28. The retaining ring 31 does not contact the reciprocating screw 25 and the inner wall of the circular groove 23, so as to prevent the retaining ring 31 from rubbing against the inner wall of the circular groove 23 and the outer surface of the reciprocating screw 25 when the slider 26 drives the retaining ring 31 to move. The inner bottom wall of the annular piston cylinder 28 is fixedly connected with a telescopic spring 32. Figure 5 The telescopic spring 32 is in a natural state. The telescopic spring 32 is set to provide a reset effect for the annular piston plate 29. The upper end of the telescopic spring 32 is fixedly connected to the bottom surface of the annular piston plate 29. The annular piston cylinder 28 is connected to the nozzle 33 fixedly connected to the inner wall of the groove plate 21. The air outlet end of the nozzle 33 is connected to the right side of the filter screen 22, that is, it is inclined to the right side of the filter screen 22, which is conducive to the subsequent air outlet of the nozzle 33 to blow to the right side of the filter screen 22, so as to clean the larger impurities on the outer surface of the filter screen 22. The bottom surface of the annular piston cylinder 28 is fixedly connected to a second check valve 34, the air inlet end of the second check valve 34 is connected to the outside, and the air outlet end of the second check valve 34 is connected to the inside of the annular piston cylinder 28, ensuring the flow direction of the air inside the annular piston cylinder 28, that is, the external air is blown to the right side of the filter screen 22 through the second check valve 34, the annular piston cylinder 28 and the nozzle 33, so that when the fence frame 14 moves downward, it automatically cleans the impurities on the outer surface of the filter screen 22, thereby extending the service life of the filter screen 22.

[0040] Working principle: When in use, connect the electric telescopic rod 18, the motor 24 and the oscillation motor 38 to the power supply, add an appropriate amount of breeding liquid to the inside of the soaking barrel 1, and pour the wheat seeds into the soaking barrel 1. When the second solenoid valve 17 is closed and the first solenoid valve 5 is opened, the operation of the first piston cylinder 2 drives the piston bottom plate 19 to move up and down on the inner wall of the electric telescopic rod 18, and the external air enters the interior of the first piston cylinder 2 through the filter 22. The air inside the first piston cylinder 2 enters the first cavity 3 and the second cavity 4 through the first one-way valve 6. Then the air inside the first cavity 3 and the second cavity 4 flows into the liquid inside the soaking barrel 1 through the second one-way valve 10, the third cavity 7 and the through hole 8. The bubbles generated on the inner bottom wall of the soaking barrel 1 move upward. When the second solenoid valve 17 is opened and the first solenoid valve 5 is closed, on the one hand, the air inside the first piston cylinder 2 flows into the interior of the soaking barrel 1 through the first one-way valve 6, the first cavity 3, the third cavity 7 and the through hole 8. The air inside the first piston cylinder 2 flows to the inside of the soaking barrel 1 through the second solenoid valve 17, the telescopic tube 41, the first cavity 15 and the third one-way valve 16, and bubbles are formed in the medicinal liquid inside the soaking barrel 1, with the bubbles on the left side facing upward and the bubbles on the right side facing downward and then upward. Changing the direction of the generated bubbles is beneficial to the bubbles inside the soaking barrel 1 to form a tumbling effect on the wheat seeds soaked in the medicinal liquid, which is more conducive to the full stirring and soaking of the wheat seeds in the medicinal liquid, and reduces the damage to the seed epidermis caused by mechanical stirring. The piston plate 12 can be driven to the left on the inner wall of the second piston cylinder 11 by rotating the threaded rod 13, so that the air inside the second piston cylinder 11 flows to the inside of the third cavity 7, thereby increasing the air pressure inside the third cavity 7 and causing the rubber ring 9 to expand toward the direction of the through hole 8, adjusting the size of the air outlet of the device, and thus adjusting the size of the bubbles generated by the device, which can optimize the distribution of bubbles in the liquid, make the bubbles stirring the wheat seeds more uniform, and improve the stirring effect of the bubbles on the wheat seeds.
