Description

Technical Field

[0001] The utility model relates to the technical field of industrial hemp breeding, in particular to a breeding device for industrial hemp seeds. Background Art

[0002] Industrial hemp flowers and leaves contain cannabidiol, which has the effects of relieving pain, reducing anxiety, protecting nerves, and inhibiting inflammation. In the process of growing industrial hemp, in order to cultivate excellent industrial hemp seeds and make the industrial hemp plants strong and easy to survive, and increase the yield of industrial hemp, it is necessary to breed industrial hemp.

[0003] The Chinese patent "An Industrial Hemp Breeding Device" authorization announcement number "CN219741362U" sets up a breeding mechanism. When the motor works clockwise, it drives the threaded rod to rotate, and the threaded rod drives the seedling tray in the fixed tray to move downward, so that the industrial hemp seeds remain moist, which is conducive to germination. When the seeds do not need culture solution, the motor drives the threaded rod to rotate counterclockwise, and the seedling tray will move upward to prevent the seeds from rotting due to excessive culture solution.

[0004] Although the upward movement of the seedling tray can prevent the cannabis seeds from absorbing too much culture solution, when the cannabis seeds are soaked in the nutrient solution in the fixed tray, the seeds will quickly absorb too much nutrient solution, causing the seeds to be too wet, thereby affecting the germination of the cannabis seeds.

[0005] Therefore, a breeding device for industrial hemp seeds is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an industrial hemp seed breeding device in order to solve the above-mentioned problem, thereby improving the problem that when the hemp seeds are soaked in the nutrient solution in the fixed plate, the seeds will quickly absorb too much nutrient solution, causing the seeds to be too wet, thereby affecting the germination of the hemp seeds.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme. A breeding device for industrial hemp seeds comprises: a seedling box, a fixed disk is installed inside the seedling box, the inner wall of the fixed disk is fixedly connected to the seedling disk, and a seedling mechanism is arranged on one side of the seedling box; wherein, the seedling mechanism comprises a motor fixedly connected to one side of the seedling box, one side of the seedling box is fixedly connected to a liquid storage tank, the output shaft of the motor is fixedly connected to a reciprocating screw rod, the other end of the reciprocating screw rod is rotatably connected to one side of the liquid storage tank, a circular disk is arranged on the surface of the reciprocating screw rod, one end of the circular disk is fixedly connected to a round rod, the inner wall of the liquid storage tank is slidably connected to a piston plate, the other end of the round rod passes through the liquid storage tank and is fixedly connected to one side of the piston plate, and a spraying assembly is arranged on the inner wall of the seedling box.

[0008] Preferably, the spray assembly includes a circular tube fixedly connected to the inner wall of the seedling box, a connecting tube is provided between the circular tube and the liquid storage tank, the surface of the circular tube is fixedly connected to liquid outlet pipes distributed in equal rows, and the surface of the liquid outlet pipes is fixedly connected to nozzles distributed in equal rows. When the hemp seeds are raised, the reciprocating screw rod in the seedling raising mechanism cooperates with the disc and the round rod, so that the round rod drives the piston plate to move back and forth, which is conducive to driving the spray assembly to operate intermittently, and is conducive to the nozzle in the spray assembly spraying the culture solution on the hemp seeds. The cooperation with the intermittent operation of the spray assembly is conducive to keeping the hemp seeds moist while avoiding soaking the seeds in the culture solution, avoiding the situation where the hemp seeds are too wet during the seedling raising, thereby improving the hemp seed raising effect.

[0009] Preferably, a drainage pipe is fixedly connected to the bottom end of the fixed plate, and the other end of the drainage pipe passes through the seedling box and the liquid storage tank in sequence to the inside of the liquid storage tank, and a one-way valve is arranged on the surface of the drainage pipe. This is conducive to allowing the culture solution in the fixed plate to flow back into the liquid storage tank, avoiding excessive culture solution from being retained in the fixed plate, and preventing the hemp seeds from being soaked in the culture solution.

[0010] Preferably, the interior of the fixed plate is filled with culture solution, and the level of the culture solution is lower than the level of the seedling tray, and the bottom end of the fixed plate is funnel-shaped. When the piston plate is reset, it is beneficial to replenish the culture solution in the liquid storage tank, so that after the piston plate is reset, the culture solution in the liquid storage tank returns to its initial state, ensuring the stability of the piston plate in squeezing the culture solution each time, thereby improving the stability of the device during operation.

[0011] Preferably, an angle is formed between the middle of the drainage pipe and the horizontal plane, and the drainage pipe is arranged as a whole at an angle, which is conducive to making the culture solution in the fixed plate flow into the liquid storage tank better.

[0012] Preferably, an angle is formed between the middle of the connecting tube and the vertical plane, which is conducive to allowing the culture solution to enter the circular tube better through the connecting tube.

[0013] Preferably, the ratio of the number of the liquid outlet pipes to the number of the circular pipes is 3: 1. This is conducive to allowing the culture solution to enter the circular pipes and then enter multiple liquid outlet pipes at the same time, and multiple liquid outlet pipes ensure that the hemp seeds on the seedling tray are fully sprayed.

[0014] Preferably, there are two round rods, and the two round rods are symmetrical about the center of the disk, so as to avoid deviation when the round rods push the piston plate to move, thereby ensuring the stability of the piston plate when moving.

[0015] The beneficial effects of the utility model are:

[0016] When the hemp seeds are raised for seedling cultivation, the reciprocating screw rod in the seedling raising mechanism cooperates with the disc and the round rod, so that the round rod drives the piston plate to move back and forth, which is conducive to driving the spraying component to run intermittently, and is conducive to the nozzle in the spraying component spraying the culture solution on the hemp seeds. The cooperation with the intermittent operation of the spraying component is conducive to keeping the hemp seeds moist, while avoiding soaking the seeds in the culture solution, avoiding the situation where the hemp seeds are too wet during seedling cultivation, thereby improving the seedling cultivation effect of the hemp seeds;

[0017] When the piston plate is reset, the drainage pipe and the one-way valve cooperate with each other to make the culture fluid in the fixed disk flow back into the liquid storage tank, which is beneficial to replenish the culture fluid in the liquid storage tank. After the piston plate is reset, the culture fluid in the liquid storage tank returns to its initial state, ensuring the stability of the piston plate in squeezing the culture fluid each time it runs, thereby improving the stability of the device during operation.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5As shown, a breeding device for industrial hemp seeds includes: a seedling box 1, a fixed plate 2 is installed inside the seedling box 1, a seedling plate 3 is fixedly connected to the inner wall of the fixed plate 2, and a seedling mechanism 4 is arranged on one side of the seedling box 1; wherein the seedling mechanism 4 includes a motor 401 fixedly connected to one side of the seedling box 1, a liquid storage tank 402 is fixedly connected to one side of the seedling box 1, a reciprocating screw rod 403 is fixedly connected to the output shaft of the motor 401, the other end of the reciprocating screw rod 403 is rotatably connected to one side of the liquid storage tank 402, a disc 404 is arranged on the surface of the reciprocating screw rod 403, one end of the disc 404 is fixedly connected to a round rod 405, a piston plate 406 is slidably connected to the inner wall of the liquid storage tank 402, the other end of the round rod 405 passes through the liquid storage tank 402 and is fixedly connected to one side of the piston plate 406, and a spraying assembly 407 is arranged on the inner wall of the seedling box 1.

[0026] A through hole is provided on the surface of the seedling tray 3, and the size of the through hole is smaller than the size of the hemp seeds. When it is necessary to grow seedlings of the hemp seeds, the hemp seeds are placed on the seedling tray 3 and evenly dispersed. The liquid storage tank 402 is filled with culture solution. After the hemp seeds are placed, the motor 401 is started, and the output shaft of the motor 401 rotates to drive the reciprocating screw 403 to rotate. The reciprocating screw 403 is in the form of two thread grooves with the same pitch and opposite rotation directions, and the two ends are connected by a transition curve. Through the rotation of the reciprocating screw, the side of the spiral groove pushes the slider placed in the spiral groove to make axial reciprocating motion. Therefore, when the reciprocating screw 403 rotates, it drives the disc 404 to move. When the disc 404 moves, it drives the round rod 405 to move synchronously. The surface of the round rod 405 is slidably connected to the inner wall of the liquid storage tank 402. When the round rod 405 moves, it will push the piston plate 406 to move synchronously and squeeze the culture solution in the liquid storage tank 402. At this time, the spraying component 407 is running.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the spray assembly 407 includes a circular tube 4071 fixedly connected to the inner wall of the seedling box 1, a connecting tube 4072 is arranged between the circular tube 4071 and the liquid storage tank 402, and the surface of the circular tube 4071 is fixedly connected with liquid outlet pipes 4073 distributed in equal rows, and the surface of the liquid outlet pipes 4073 is fixedly connected with nozzles 4074 distributed in equal rows. An angle is formed between the middle part of the connecting tube 4072 and the vertical plane. The number ratio of the liquid outlet pipes 4073 to the circular tube 4071 is 3:1. The number of round rods 405 is two, and the two round rods 405 are symmetrical with the center of the disk 404.

[0028] When the culture liquid in the liquid storage tank 402 is squeezed, it will enter the connecting pipe 4072, and enter the circular tube 4071 through the connecting pipe 4072, and enter the multiple liquid outlet pipes 4073 at the same time under the action of the circular tube 4071, and be sprayed out at the same time through the multiple nozzles 4074, so that the culture liquid is sprayed on the surface of the hemp seeds. When the reciprocating screw rod 403 rotates and the disc 404 cannot continue to move forward, under the action of the reciprocating screw rod 403, the disc 404 moves in the opposite direction to reset, and the circular rod 405 drives the piston plate 406 to reset. At this time, the culture liquid in the liquid storage tank 402 loses its squeezing, and the culture liquid in the liquid storage tank 402 cannot enter the connecting pipe 4072. Therefore, under the action of the reciprocating screw rod 403, the circular rod 405 drives the piston plate 406 to move back and forth, so that the spraying assembly 407 runs intermittently to spray the culture liquid on the hemp seeds.

[0029] like Figure 3 and Figure 4 As shown, a drain pipe 4075 is fixedly connected to the bottom end of the fixed plate 2, and the other end of the drain pipe 4075 sequentially passes through the seedling box 1 and the liquid storage tank 402 to the inside of the liquid storage tank 402, and a one-way valve 4076 is arranged on the surface of the drain pipe 4075. The inside of the fixed plate 2 is filled with culture fluid, and the level of the culture fluid is lower than the level of the seedling plate 3, and the bottom end of the fixed plate 2 is funnel-shaped. An angle is formed between the middle part of the drain pipe 4075 and the horizontal plane, and the drain pipe 4075 is arranged inclined as a whole.

[0030] After the culture solution sprayed by the nozzle 4074 comes into contact with the hemp seeds, a small amount of culture solution will remain on the surface of the seeds to keep the seeds moist, and a larger part will flow into the fixed plate 2 under the action of the through holes on the surface of the seedling tray 3, and will flow back to the liquid storage tank 402 under the action of the drain pipe 4075 and the one-way valve 4076.

[0031] When the utility model is used, when it is necessary to raise hemp seeds, the hemp seeds are evenly dispersed on the seedling tray 3, the motor 401 is started to drive the reciprocating screw rod 403 to rotate, so that the disc 404 drives the round rod 405 to move, and when the round rod 405 moves, it will push the piston plate 406 to move synchronously and squeeze the culture liquid in the liquid storage tank 402 to pass through the connecting pipe 4072 and the round pipe 4071 in sequence and enter into multiple liquid outlet pipes 4073 at the same time, and spray out through multiple nozzles 4074 at the same time, so that the culture liquid is sprayed on the surface of the hemp seeds, and part of the culture liquid will flow into the fixed plate 2 after contacting with the hemp seeds. When the reciprocating screw 403 rotates to drive the disc 404 to reset, the round rod 405 drives the piston plate 406 to reset. At this time, the culture solution in the liquid storage tank 402 loses its squeezing. At the same time, when the piston plate 406 is reset, the culture solution in the fixed disk 2 will flow back into the liquid storage tank 402 under the action of the drain pipe 4075 and the one-way valve 4076, so that the liquid storage tank 402 returns to its initial state. Therefore, under the action of the reciprocating screw 403, the round rod 405 drives the piston plate 406 to move back and forth, so that the spraying assembly 407 runs intermittently to spray the culture solution on the hemp seeds to prevent the hemp seeds from being over-wet.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
