Description

Technical Field

[0001] This utility model relates to the field of seed soaking technology, and in particular to a seed soaking device for agricultural seed breeding. Background Technology

[0002] Saltwater seed selection involves placing seeds in a saltwater solution of a certain concentration and using buoyancy to separate good seeds from bad seeds. Saltwater has a greater buoyancy than fresh water, which can float some immature seeds, while plump seeds suitable for sowing sink to the bottom.

[0003] Existing seed selection devices mostly involve pouring brine into a basin or bucket, adding seeds, and then soaking and selecting the seeds. After separation, it is necessary to manually remove the floating bad seeds and then pour the qualified seeds from the bottom of the device back into the brine for separation. This is labor-intensive, time-consuming, and very inconvenient. In order to address this technical problem, this application proposes a seed soaking device for agricultural seed selection and breeding. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a seed soaking device for agricultural seed selection. After sorting, the bottom can be sealed to prevent seeds from passing through. Then, the pressure rod is pushed down to push the rubber stopper out of the discharge pipe, allowing qualified seeds at the bottom of the soaking tank to be discharged from the discharge pipe, while bad seeds are blocked by the baffle plate. Subsequently, the fixing frame can be removed from the soaking tank to collect and clean the bad seeds. The operation is convenient and does not require manual repeated retrieval of seeds.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A seed soaking device for agricultural seed breeding includes a soaking tank. An inlet pipe is inserted through the left end of the soaking tank, and a control valve is installed on the outer wall of the inlet pipe. A fixing frame is installed at the top of the soaking tank, and a support frame is fixedly connected to one inward end of each fixing frame. A fixing block is fixedly connected to one inward end of each support frame. A connecting rod is connected to the top of the fixing block via an elastic component. A baffle plate is fixedly connected to the bottom end of the connecting rod. Limiting rods are fixedly connected to both the left and right ends of the connecting rod. Slots are provided on both the front and rear sides of the top of the fixing block. A discharge component is installed at the right end of the soaking tank.

[0007] Furthermore, the elastic component includes a spring fixedly connected to the top of the second fixed block, the top of the spring being fixedly connected to the first fixed block, and the outer wall of the connecting rod being rotatably connected to the inner wall of the first fixed block.

[0008] Furthermore, both ends of the fixed block are fixedly connected to limit rods, and the outer walls of the limit rods are slidably connected to the inner wall of the support frame.

[0009] Furthermore, a handwheel is fixedly connected to the top of the connecting rod, the outer wall of the connecting rod is set on the inner wall of the second fixing block, and multiple through holes are opened at the top of the baffle plate.

[0010] Furthermore, the outer walls of the second limiting rod are all set on the inner wall of the second fixing block, and the size of the second limiting rod is adapted to the slot.

[0011] Furthermore, the discharge assembly includes a discharge pipe extending through the right end of the soaking tank, a pressure rod slidably connected to the inner wall of the discharge pipe, and a rubber stopper fixedly connected to the bottom end of the pressure rod.

[0012] Furthermore, the outer wall of the rubber plug is tightly attached to the inner wall of the discharge pipe, and a sealing plug is provided at the connection between the discharge pipe and the pressure rod.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, after sorting, the bottom can be sealed to prevent seeds from passing through. Then, the pressure rod is pushed down to push the rubber stopper out of the discharge pipe, so that the qualified seeds at the bottom of the soaking tank are discharged from the discharge pipe, while the bad seeds are blocked by the baffle. Afterwards, the fixing frame can be removed from the soaking tank to clean the bad seeds. The operation is convenient and does not require manual repeated retrieval of seeds.

[0015] 2. In this utility model, when the discharge pipe is blocked, the pressure rod can be pulled upward to allow the rubber stopper to enter the discharge pipe and compress the air inside. This allows the gas to push the blocked seeds back into the soaking tank. Then, the pressure rod can be pressed down again to push the rubber stopper out of the discharge pipe, thus resolving the blockage and allowing the seeds to be discharged again.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-3 An embodiment of this utility model provides a seed soaking device for agricultural seed breeding, including a soaking tank 1, an inlet pipe 2 passing through the left end of the soaking tank 1, a control valve 3 provided on the outer wall of the inlet pipe 2, a fixed frame 4 provided at the top of the soaking tank 1, a support frame 12 fixedly connected to one end of the fixed frame 4, a fixed block 13 fixedly connected to one end of the support frame 12, a connecting rod 8 connected to the top of the fixed block 13 through an elastic component, the elastic component including a spring 9 fixedly connected to the top of the fixed block 13, a fixed block 6 fixedly connected to the top of the spring 9, the outer wall of the connecting rod 8 rotatably connected to the inner wall of the fixed block 6, a limit rod 5 fixedly connected to both the left and right ends of the fixed block 6, the outer walls of the limit rod 5 slidably connected to the inner wall of the support frame 12, and a baffle plate 14 fixedly connected to the bottom end of the connecting rod 8.

[0023] Specifically, brine can be injected into the soaking tank 1 through the inlet pipe 2 to sort the seeds. During the sorting process, the handwheel 7 can be pushed to compress the spring 9 of the fixed block 6, which will generate elastic force and cause the connecting rod 8 to push the baffle 14 downward. Then, the handwheel 7 can be released to reset the fixed block 6 under the elastic force of the spring 9, which will cause the connecting rod 8 to drive the baffle 14 upward, thus accelerating the seed sorting and preventing the seeds from depositing on the surface of the baffle 14 during static sorting, which would affect subsequent operations.

[0024] A handwheel 7 is fixedly connected to the top of the connecting rod 8. The outer wall of the connecting rod 8 is set on the inner wall of the second fixed block 13. Multiple through holes are opened at the top of the baffle plate 14. Limiting rods 17 are fixedly connected to both the left and right ends of the connecting rod 8. The outer walls of the limiting rods 17 are set on the inner wall of the second fixed block 13. The size of the limiting rods 17 is adapted to the slots 16. Slots 16 are opened on both the front and rear sides of the top of the second fixed block 13. A discharge assembly is set at the right end of the soaking tank 1. The discharge assembly includes a discharge pipe 11 passing through the right end of the soaking tank 1. A pressure rod 10 is slidably connected to the inner wall of the discharge pipe 11. A rubber plug 15 is fixedly connected to the bottom end of the pressure rod 10. The outer wall of the rubber plug 15 is tightly attached to the inner wall of the discharge pipe 11. A sealing plug is set at the connection between the discharge pipe 11 and the pressure rod 10.

[0025] Specifically, after sorting, pull the handwheel 7 upwards to raise the connecting rod 8, causing the baffle plate 14 to rise. The top of the baffle plate 14 then presses against the bottom of the fixed frame 4, sealing the gap between the fixed frame 4 and the baffle plate 14. At this point, the limiting rod 17 will disengage from the fixed block 13. Then, rotate the handwheel 7 to align the limiting rod 17 with the slot 16. Next, release the handwheel 7 to allow the limiting rod 17 to engage with the slot 16, limiting the baffle plate 14. Although the baffle plate 14 descends a certain distance, the gap between it and the fixed frame 4 is still smaller than the seed size, preventing seeds from passing through. Then, push the pressure rod 10 downwards to push the rubber stopper 15 out of the discharge pipe 11. At this point, the qualified seeds deposited at the bottom of the soaking tank 1 will mix with the brine and flow out of the discharge pipe. The brine is discharged through pipe 11. During this process, the brine will pass normally through the hole at the top of the baffle plate 14. The bad seeds floating on the water surface are blocked by the baffle plate 14, thus separating them from the qualified seeds and preventing them from being discharged from the discharge pipe 11 together. Afterwards, the fixing frame 4 can be removed from the soaking tank 1 to clean the bad seeds directly. The operation is convenient and does not require manual repeated retrieval of seeds. When the discharge pipe 11 is blocked, the pressure rod 10 can be pulled upward to allow the rubber plug 15 to enter the discharge pipe 11 and compress the air inside. This allows the gas to push the blocked seeds back into the soaking tank 1. Then, the pressure rod 10 can be pressed again to push the rubber plug 15 out of the discharge pipe 11 to resolve the blockage and allow the seeds to be discharged again.

[0026] Working Principle: In actual use, firstly, control valve 3 is opened to inject brine into the soaking tank 1 through the inlet pipe 2. When the water level reaches the bottom of limit rod 5, control valve 3 is closed to stop the injection. Then, the seeds to be selected are poured into the soaking tank 1. Since the density of shriveled and insect-damaged seeds is much lower than that of plump seeds, the bad seeds will float on the surface of the salt, while the seeds suitable for planting will sink to the bottom of the soaking tank 1. During this process, the operator can repeatedly press and release handwheel 7 to move fixed block 6 downwards, compressing spring 9 and generating elastic force, which causes connecting rod 8 to push the baffle plate 14 down. Then, when the operator releases handwheel 7, fixed block 6 will return to its original position under the elastic force of spring 9, causing connecting rod 8 to drive the baffle plate 14 upwards, stirring the brine inside the soaking tank 1, accelerating the seed sorting, and at the same time, the baffle plate 14 moves continuously inside the brine to prevent qualified seeds from accumulating on top of the baffle plate 14 and failing to sink to the bottom. After sorting is completed, the operator can... Pulling the handwheel 7 upwards disengages the limiting rods 17 on both sides of the connecting rod 8 from the fixing block 13. Then, rotating the handwheel 7 causes the connecting rod 8 to rotate inside the fixing block 6, aligning the limiting rods 17 with the slot 16. Releasing the handwheel 7 causes the limiting rods 17 to engage with the slot 16. At this point, the top of the baffle 14 will be in contact with the bottom of the fixing frame 4, preventing the seeds from sinking through the gap between the fixing frame 4 and the baffle 14. Then, pressing the pressure rod 10 downwards pushes the rubber plug 15 out of the discharge pipe. Inside the 11, the seeds deposited at the bottom of the soaking tank 1 will be collected by being discharged from the outlet pipe 11 along with the brine. The bad seeds floating on the top of the brine will be blocked by the baffle plate 14. The fixing frame 4 can be directly removed from the soaking tank 1 for cleaning. If the outlet pipe 11 is blocked during the feeding process, the pressure rod 10 can be pulled upward to allow the rubber plug 15 to re-enter the outlet pipe 11 and compress the air inside the outlet pipe 11 to disperse the seeds blocked in the outlet pipe 11, ensuring normal feeding.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
