Corn breeding germination device

Abstract

The invention relates to the technical field of breeding equipment, and particularly discloses a corn breeding germination device. The device comprises a box body and a top cover, wherein the interior of the box body is divided into an upper area and a lower area through a middle partition plate. A supporting structure used for placing the bearing frame is arranged on the middle partition plate, and corn seeds can be borne on the bearing frame. When the rotating piece ascends, the water body in the lower half area of the box body can be extruded, so that the air pressure in the area is increased. The solubility of oxygen in water can be remarkably improved by controlling the air pressure within the range of 1-3 atmospheric pressures. The oxygen environment with high solubility can enhance the respiration of the corn seeds and promote the physiological metabolic activity of the corn seeds. Meanwhile, the water absorption rate and the oxygen utilization rate of the seeds under the high-pressure condition are improved, and then the germination efficiency and the germination rate of the corn seeds are effectively improved. According to the design, through the synergistic effect of a mechanical structure and air pressure control, an optimized growth environment is provided for corn breeding and germination.

Description

Technical Field

[0001] The present invention relates to the technical field of agricultural breeding equipment, and specifically to a corn breeding germination device that integrates precise control of environmental parameters, seed pretreatment and germination process. The device is particularly suitable for large-scale seedling cultivation scenarios on large farms, and can significantly shorten the germination period of corn seeds and improve the germination rate.

Although the corn seed storage method disclosed in CN201711237091.0 improves the seed preservation quality through the steps of optimization, drying, sterilization, etc., it does not involve an optimization device for the germination process and cannot solve the problem of a long germination period.

[0003] 2. The oxygen-controlled germination equipment proposed in CN201920052905.1 can adjust the oxygen content, but the system structure is complex and the integrated control of seed soaking pretreatment and germination process is not achieved, which makes it difficult to meet the needs of efficient seedling cultivation in large farms.

[0004] 3.

It should be understood that the specific embodiments described herein are only used to explain the present invention and do not constitute a limitation on the scope of the invention. Embodiment 1

[0027] Reference Figure 1-5 A corn breeding and germination device comprises a box body 101 and a top cover 102. The interior of the box body 101 is divided into two upper and lower areas by a middle partition 108. The middle partition 108 is used to place a support frame 201 and corn seeds. The lower part of the middle partition 108 and the rotating member 501 are used to hold water. The water at least covers the support frame 201. The rotating member 501 is driven to rotate by a driving motor 107, and cooperates with a pull bolt 401 and a threaded groove 507 on the side wall of the rotating member 501 to realize rotation and simultaneous ascent, pressurizing the area, increasing the gas solubility, and reducing or dissolving the bubble volume.

[0028] Among them, a driving motor 107 is installed at the inner bottom end of the box body 101. The output shaft of the driving motor 107 is connected to the transmission rod 503, the cross-section of the transmission rod 503 is rectangular, and is inserted into the middle of the rotating member 501. The rotating member 501 moves along the axial direction of the transmission rod 503 and is driven to rotate by the transmission rod 503. A group of blades 502 are sleeved on the side wall located at the top of the rotating member 501, and a thread groove 507 is provided under the blade 502. The thread groove 507 cooperates with the end of the pull bolt 401 to ensure that the rotating member 501 can rise during the rotation process. In addition, the blades 502 are integrally connected to the top wall of the rotating member 501. The top of the transmission rod 503 is integrally connected to a top limit seal 504, and a sealing ring is bonded to the bottom end thereof for limiting and sealing after the rotating member 501 rises. The bottom of the transmission rod 503 is integrally connected with a bottom limit seal 505, and a sealing ring is bonded to the top thereof, which is used to limit and seal when the rotating member 501 reaches the lowest position. The outer side of the transmission rod 503 is sleeved with a plurality of convex edge sealing rings 506 to ensure that the rotating member 501 remains sealed during the upward movement.

[0029] A through hole 301 is formed on the middle partition plate 108 and passes through the middle partition plate 108 . The cross section of the through hole 301 is funnel-shaped, and the inner wall of the through hole 301 is covered with arc-shaped convex strips 302 .

[0030] A water inlet 105 and a water outlet 106 are provided on the outer side of the box body 101 , wherein the water inlet 105 is located between the sealing cover 111 and the middle partition 108 , and the water outlet 106 is located between the middle partition 108 and the rotating member 501 .

[0031] A bottom fixed annular plate 109 integrally formed with the box body 101 is disposed below the rotating member 501 , and a sealing ring is disposed on the bottom fixed annular plate 109 .

[0032] The axis of the pull bolt 401 is perpendicular to the axis of the box 101 . The pull bolt 401 is connected to the outer wall of the box 101 through a spring 402 . One end of the spring 402 is bonded to the surface of the box 101 , and the other end is bonded to the pull bolt 401 .

[0033] The inner wall of the upper end of the box body 101 is integrally connected with the top auxiliary sealing annular plate 110, and a sealing cover 111 is provided above the top auxiliary sealing annular plate 110. A sealing ring is embedded between the sealing cover 111 and the top auxiliary sealing annular plate 110. The top cover 102 is fixed to the box body 101 by a lock 104. The fixed top rod 103 in the middle of the top cover 102 is rotated so that the bottom end of the fixed top rod 103 presses the sealing cover 111 downward, thereby achieving the sealing of the port. A support bracket 201 is installed on the middle partition 108. The support bracket 201 is designed to support corn planting, and the support pillar 202 at the bottom thereof is precisely matched with the groove at the top of the middle partition 108. Embodiment 2

[0034] Reference Figure 1-5 A corn breeding germination device includes a box body 101 and a top cover 102. The interior of the box body 101 is divided into two upper and lower areas by a middle partition 108: 1. Middle partition 108: The plate surface is used to place the support frame 201 and corn seeds. The bottom is provided with a funnel-shaped through hole 301 which passes through from top to bottom. The inner wall of the through hole 301 is densely covered with arc-shaped convex strips 302, which can generate resistance when water flows through and reduce disturbance to the upper seeds.

[0035] A water storage space is formed between the bottom of the partition and the rotating member 501 , and the water level must at least be above the supporting frame 201 . The driving motor 107 is installed at the bottom of the box 101, and its output shaft is connected to the transmission rod 503 of rectangular cross section. The rotating member 501 is sleeved on the outside of the transmission rod 503, can move along the rod axial direction and is driven to rotate by the transmission rod 503.

[0036] The top periphery of the rotating member 501 has fixed blades 502 for stirring the water. The peripheral wall thereof is provided with threaded grooves 507 which cooperate with the ends of the horizontally arranged pull bolts 401 to enable the rotating member 501 to generate an upward motion when rotating.

[0037] The top of the transmission rod 503 is fixed to the top limit seal 504 and the bottom limit seal 505, and the sealing limit is achieved during the lifting and lowering of the rotating part 501 through the sealing ring; a convex edge sealing ring 506 is sleeved on the outside of the rod body to ensure the sealing when the rotating part 501 moves upward. A water inlet 105 (located between the sealing cover 111 and the middle partition 108 ) and a water outlet 106 (located between the middle partition 108 and the rotating member 501 ) are provided on the outside of the box body 101 .

[0038] The pull bolt 401 is elastically connected to the outer wall of the box 101 through the spring 402, and its axis is perpendicular to the axis of the box 101. When the rotating member 501 rises to a set height, the pull bolt 401 retracts under the action of the spring 402 and abuts against the lower end surface of the rotating member 501 to prevent it from falling back.

[0039] The top auxiliary sealing annular plate 110 is fixed to the inner wall of the upper end of the box body 101, and the sealing cover 111 cooperates with the plate through a sealing ring. The top cover 102 is fixed to the box body 101 through a lock 104. The fixed top rod 103 in the middle of the top cover 102 can be rotated to press the sealing cover 111 downward to achieve top sealing; A bottom fixed annular plate 109 integrally formed with the box body 101 is disposed below the rotating member 501 , and a sealing ring is disposed on the bottom fixed annular plate 109 . The corn seeds are placed on the support frame 201 and accurately positioned through the grooves of the support 202 and the middle partition 108.

[0040] Install the sealing cover 111 and close the top cover 102, and tighten the top rod 103 to ensure the top is sealed. The driving motor 107 is started, and the transmission rod 503 drives the rotating member 501 to rotate. Due to the cooperation between the thread groove 507 and the pull bolt 401, the rotating member 501 rises along the transmission rod 503 while rotating, forming a pressurized environment (the air pressure can reach 1-3 atmospheres) in the water storage area.

[0041] The blades 502 stir the water synchronously to accelerate the dissolution of oxygen. When the rotating member 501 rises above the pull bolt 401, the pull bolt 401 retracts under the action of the spring 402 and presses against the lower end surface of the rotating member 501. At this time, the rotating member 501 only rotates without falling back, and the high-pressure stirring state is continuously maintained. The funnel-shaped structure of the through hole 301 and the arc-shaped convex strip 302 on the middle partition 108 can generate resistance when water flows through, so that the upper water body remains relatively still, reducing the scouring interference to the seeds. When pressure relief is required, the pull bolt 401 is pulled outward, and the rotating member 501 is reset under the action of water pressure and gravity.

[0042] Open the water outlet 106 valve to drain the water, and then wait for the seeds to germinate. 1. The high-pressure environment increases the solubility of oxygen in water, promotes seed respiration, shortens the soaking time to 3-12 hours, and significantly improves germination efficiency.

[0043] 2. The rotating stirring and sealing design ensures that oxygen is evenly dissolved to prevent seeds from rotting due to lack of oxygen.

[0044] 3. Manual pressure relief and drainage does not require opening the box 101, reducing the risk of external pollution.

[0045] 4. The through-hole and convex strip structure can effectively stabilize the upper water body and optimize the seed growth environment while ensuring water circulation.

[0046] The above embodiments are merely exemplary of the present invention, and those skilled in the art may make various improvements or modifications without departing from the core principle of the invention, which should all be included in the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims and their equivalent technical solutions.
