Description

Technical Field

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

[0002] Soaking corn seeds in water to promote germination is a common pretreatment method that can improve the germination rate.

[0003] In existing technologies, seeds often float on the surface of water during soaking because their density is lower than that of the liquid, with only one side in contact with the soaking solution. This reduces water absorption efficiency and makes it difficult to separate the seeds from the soaking solution after soaking. For example, a corn seed germination soaking device disclosed in CN220441243U improves soaking efficiency to some extent by adding a fixed frame, screw, and pressure screen inside the soaking tank, and using a servo motor to drive the screw to press the pressure screen downwards, thus pressing the seeds floating on the surface into the soaking solution. This type of device uses a fixed soaking method, relying on the pressure screen to fix the seeds in the liquid, solving the problem of seed floating. However, the above-mentioned fixed soaking device still has shortcomings in use:

[0004] On the one hand, the soaking solution remained basically still during the soaking process, without dynamic stirring or aeration, and the seeds could not obtain enough oxygen when submerged in static liquid for a long time.

[0005] On the other hand, the lifting of the screen box in existing soaking devices usually relies on manual operation or simple mechanical structures, lacking lifting control. This results in the inability to achieve alternating circulation of soaking liquid and oxygen exposure during the soaking and liquid exchange process, leading to insufficient oxygen supply and low liquid exchange efficiency in existing equipment, making it difficult to meet the requirements of high-efficiency germination. Utility Model Content

[0006] The purpose of this invention is to solve the problems of insufficient oxygen and uneven mixing of nutrient solution in the corn seed germination soaking process in the prior art, and to propose a corn seed germination soaking device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A corn seed germination soaking device includes a mounting base and a water tank with a rectangular groove. A support slide rail is fixedly mounted on the mounting base, and a slider is slidably mounted on the support slide rail. A lifting mechanism for lifting and lowering corn seeds is fixedly mounted on the slider. A seed soaking sieve box for placing corn seeds is movably mounted at the lower end of the lifting mechanism. An oscillation mechanism for oscillating the water tank is provided on the mounting base.

[0009] Preferably, the water tank is installed at the upper end of the mounting base, the mounting base is provided with a limiting rod for limiting the position of the water tank, and the outer wall of the water tank is provided with a limiting groove for sliding the limiting rod.

[0010] Preferably, the oscillation mechanism includes an assembly box welded to a mounting base. A sliding plate fixedly mounted on the bottom of the water tank is slidably fitted onto the upper end of the assembly box. A second drive motor is fixedly mounted on the right side of the assembly box. A transmission shaft is fixedly fitted onto the output end of the second drive motor. A first H-shaped grooved wheel is movably mounted on the transmission shaft. A hand-tightening screw is rotatably provided on the right wall of the assembly box. An adjusting flywheel is rotatably mounted at the bottom end of the hand-tightening screw. A rotating shaft is horizontally fixedly mounted on the other side of the transmission shaft where the H-shaped grooved wheel is mounted. Second H-shaped grooved wheels are rotatably mounted at both ends of the rotating shaft. The first H-shaped grooved wheel and the second H-shaped grooved wheel are respectively provided with a first base and a second base distributed in parallel. A traction rod for tilting the second H-shaped grooved wheel is connected between the first base and the second base by a pin.

[0011] Preferably, the second H-shaped grooved wheel has annular grooves on both sides of the protrusions, the slide plate has a circular through hole, a telescopic rod is fixedly installed in the circular through hole, the bottom of the telescopic rod is welded to the water tank, the top of the telescopic rod is rotatably connected to an oscillating ball that drives the slide plate to move left and right, and the annular groove limits the movement of the oscillating ball.

[0012] Preferably, the lifting mechanism includes a C-shaped frame fixedly mounted on the slider, a first drive motor fixedly mounted on the upper end of the C-shaped frame, a guide wheel welded to the C-shaped frame mounted on the output end of the drive motor, a steel wire rope rotatably mounted on the guide wheel, a concave hook fixedly mounted on the lower end of the steel wire rope, a hook movably mounted on the concave hook, and a traction rope for pulling the seed soaking screen box mounted on the lower end of the hook.

[0013] Preferably, the bottom of the soaking sieve box is provided with a seepage hole for water inlet and ventilation, and the top of the soaking sieve box is provided with a rectangular door.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This utility model utilizes a second drive motor to drive the transmission shaft to rotate, causing the second H-shaped grooved wheel to rotate. By adjusting the forward and backward displacement of the flywheel through a hand-tightening screw, the first H-shaped grooved wheel is pushed forward along the transmission rod, forcing the second H-shaped grooved wheel to produce an angular offset. The oscillating ball in the groove of the second H-shaped grooved wheel is squeezed by the groove wall and produces a left-right reciprocating motion, which drives the rigidly connected sliding plate to move horizontally, ultimately driving the water tank to oscillate left and right. This motion makes the nutrient solution evenly mixed, promotes the absorption of corn seeds, and helps to improve the germination speed.

[0016] 2. This utility model uses a first drive motor to rotate a guide wheel, which pulls a steel wire rope down along the wheel groove, driving the seed soaking screen box to move into the water tank, so that the corn seeds are fully immersed in the nutrient solution; then the motor rotates in the opposite direction, lifting the screen box above the liquid surface through the steel wire rope, promoting the seeds to absorb oxygen and avoiding necrosis due to lack of oxygen, thereby significantly improving the seed soaking efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-6A corn seed germination soaking device includes a mounting base 1 and a water tank 7 with a rectangular groove. The water tank 7 is mounted on the upper end of the mounting base 1. A limiting rod 9 is provided on the mounting base 1 to limit the movement of the water tank 7. A limiting groove 8 is provided on the outer wall of the water tank 7 to slide and fit the limiting rod 9. Two limiting grooves 8 and limiting rods 9 are provided to limit the movement of the water tank 7 during vibration. The limiting grooves 8 and limiting rods 9 are located on both sides of the outer wall of the water tank 7. The water tank 7 can be made of high-density polyethylene (HDPE). HDPE has excellent chemical inertness and is resistant to acids, alkalis, and salts. It is also non-toxic, odorless, food-grade HDPE, safe and reliable, and has the advantages of high strength, toughness, impact resistance, light weight, and moderate cost. It should be noted that the water tank 7 is filled with an unshaken nutrient solution.

[0026] A support rail 2 is fixedly mounted on the mounting base 1. A slider 3 is slidably mounted on the support rail 2. A lifting mechanism 4 for lifting and lowering corn seeds is fixedly mounted on the slider 3. The lifting mechanism 4 includes a U-shaped frame 41 fixedly mounted on the slider 3. A first drive motor 42 is fixedly mounted on the upper end of the U-shaped frame 41. A guide wheel 43 welded to the U-shaped frame 41 is mounted on the output end of the drive motor. A steel wire rope 44 is rotatably mounted on the guide wheel 43. It should be noted that the guide wheel 43 has a groove for guiding the steel wire rope 44. The lower end of the steel wire rope 44 is fixed... A concave hook 45 is fixedly installed. The concave hook 45 consists of a disc and a U-shaped block. A hook 46 is movably mounted on the concave hook 45. The hook 46 consists of a rod that fits into the U-shaped block and a circular plate that connects to the traction rope 47. The lower end of the hook 46 is equipped with a traction rope 47 for pulling the seed soaking screen box 5. The traction rope 47 is symmetrically distributed on the four sides of the seed soaking screen box 5, and the other end of the traction rope 47 is connected to the circular plate. The traction rope 47 can be made of ultra-high molecular weight polyethylene rope. Ultra-high molecular weight polyethylene rope has the advantage of hydrolysis resistance and can be soaked in nutrient solution for a long time.

[0027] The lower end of the lifting mechanism 4 is equipped with a seed soaking sieve box 5 for placing corn seeds. The bottom of the seed soaking sieve box 5 has a seepage hole 51 for water inlet and ventilation. The upper end of the seed soaking sieve box 5 has a rectangular door 52. The door frame of the rectangular door 52 is fitted with a food-grade silicone sealing strip.

[0028] The mounting base 1 is equipped with an oscillation mechanism 6 for oscillating the water tank 7. The oscillation mechanism 6 includes an assembly box 61 welded to the mounting base 1. The assembly box 61 is a concave box, and sliding grooves are provided at both ends of the assembly box 61. A sliding plate 62 fixedly installed at the bottom of the water tank 7 is slidably fitted on the upper end of the assembly box 61. A second drive motor 63 is fixedly installed on the right side of the assembly box 61. A transmission shaft 64 is fixedly fitted on the output end of the second drive motor 63. A first H-shaped grooved wheel 65 is movably installed on the transmission shaft 64. A hand-tightening screw 67 is rotatably provided on the right wall of the assembly box 61. Two through holes are provided on the right side of the assembly box 61 for installing the second drive motor 63 and the hand-tightening screw 67. An adjusting flywheel 66 is rotatably installed at the bottom end of the hand-tightening screw 67. A rotating shaft 612 is horizontally fixedly installed on the other side of the transmission shaft 64 where the first H-shaped grooved wheel 65 is installed. A through hole is provided for fixing and installing the rotating shaft 612. The two ends of the rotating shaft 612 are rotatably mounted with second H-shaped grooved wheels 611. Both sides of the second H-shaped grooved wheels 611 are provided with annular grooves 613. A circular through hole 616 is provided on the slide plate 62. A telescopic rod 615 is fixedly installed in the circular through hole 616. The bottom of the telescopic rod 615 is welded to the water tank 7. The top of the telescopic rod 615 is rotatably connected to an oscillating ball 614 that drives the slide plate 62 to move left and right. The annular groove 613 limits the oscillating ball 614 and partially encloses the oscillating ball 614, thereby preventing the oscillating ball 614 from falling off when the second H-shaped grooved wheel 611 is offset and rotated. The first H-shaped grooved wheel 65 and the second H-shaped grooved wheel 611 can be made of 42CrMo alloy structural steel. 42CrMo alloy structural steel has the advantages of wear resistance, fatigue fracture resistance and corrosion resistance.

[0029] The first H-shaped grooved wheel 65 and the second H-shaped grooved wheel 611 are respectively provided with a first base 68 and a second base 610 distributed in parallel. The first base 68 and the second base 610 are provided on the outer walls of the first H-shaped grooved wheel 65 and the second H-shaped grooved wheel 611 respectively. A traction rod 69 for tractioning the second H-shaped grooved wheel 611 to tilt is connected between the first base 68 and the second base 610 by a pin.

[0030] It should be noted that the specific models and specifications of the first drive motor 42 and the second drive motor 63 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation methods adopt existing technologies in this field, so they will not be elaborated here.

[0031] The functional principle of this utility model can be explained through the following operation methods:

[0032] Pour the corn seeds into the seed soaking sieve box 5;

[0033] The second drive motor 63 drives the transmission shaft 64 to rotate, which in turn causes the second H-shaped grooved wheel 611 to rotate. By rotating the hand screw 67, the adjusting flywheel 66 is pushed to move horizontally, causing the first H-shaped grooved wheel 65 to move to the left under the squeezing action of the adjusting flywheel 66. The first H-shaped grooved wheel 65 pushes the traction rod 69, forcing the second H-shaped grooved wheel 611 to deflect axially. The deflected second H-shaped grooved wheel 611 periodically collides with the oscillating ball 614 through the flange of its annular groove 613.

[0034] The sidewall of the annular groove 613 forms a three-dimensional motion constraint on the oscillating ball 614, which can only move horizontally back and forth along the direction of the groove. The oscillating ball 614 rigidly drives the telescopic rod 615, which drives the slide plate 62 to perform left and right translation. Under the limitation of the limiting slide groove 8 and the limiting rod 9, the nutrient solution in the water tank 7 is directionally oscillated and shaken evenly.

[0035] At this point, hook 46 is attached to the U-shaped slot of concave hook 45;

[0036] Subsequently, the first drive motor 42 is started to rotate forward, driving the guide wheel 43 to rotate and release the steel wire rope 44, so that the seed soaking screen box 5 is pulled down in the vertical direction at a uniform speed by the traction rope 47, thereby making the corn seeds completely submerged in the nutrient solution to complete the water absorption process.

[0037] After that, the first drive motor 42 is switched to the reverse drive guide wheel 43 to wind up the steel wire rope 44, and the traction rope 47 is lifted through the rigid connection between the concave hook 45 and the hook 46, which drives the seed soaking screen box 5 to rise above the liquid surface.

[0038] During this exposure phase, the corn seeds exchange gases through the permeation holes 51, effectively promoting aerobic respiration and preventing anaerobic necrosis, thereby significantly improving the soaking efficiency and germination activity of the corn seeds.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
