Description

Technical Field

[0001] The present invention relates to a cultivation device and method for corn seeds, belonging to the technical field of seed cultivation. Background Art

[0002] Corn has strong drought tolerance, cold tolerance, barren tolerance and excellent environmental adaptability. As a high-yield food crop, corn is an important feed source for animal husbandry, aquaculture, etc. There are many varieties of corn seeds on the market. In order to breed excellent corn varieties, it is necessary to apply the incubators commonly used in breeding laboratories. The incubator can adjust indicators such as temperature, humidity, and light intensity according to needs, and these indicators will all affect the germination and growth of corn seeds in the culture dish. In addition, there is also an important indicator, which is the direction in which the corn seeds are initially placed in the culture medium. Usually, when the embryo is placed downward, the corn seeds have a faster germination speed, a higher germination index, a higher vigor index, and the seedlings grow faster and healthier.

[0003] Specifically, when breeding and cultivating different varieties of corn seeds and wanting to know the influence of a certain indicator on the germination and growth of different varieties of corn seeds, it is necessary to keep all other indicators as uniform as possible. Indicators such as temperature, humidity, and light intensity are relatively easy to control and adjust, but the placement position of corn seeds in the culture medium is not easy to control. It is necessary for operators to hold tweezers and place the corn seeds into the culture medium one by one according to the direction requirements. This method has a large labor intensity, low efficiency, and it is difficult to ensure the accuracy of the placement direction of corn seeds. There is no such device or equipment in the prior art for controlling the direction of seeds placed in the culture medium during the process of seed breeding and cultivation. Summary of the Invention

[0004] The purpose of the present invention is to solve the technical problem in the prior art that the direction of corn seeds placed in the culture medium can only be controlled by manual operation, which has a large labor intensity, low efficiency, and it is difficult to ensure the accuracy of the direction, and to provide a cultivation device and method for corn seeds.

[0005] The present invention is realized through the following technical solutions: That is, a cultivation device for corn seeds includes a screening mechanism for screening corn seeds and a culture dish, and also includes an incubator. The screening mechanism includes a base, on which a rotation motor and a circular vibrating tray are installed. A vibration motor is installed at the bottom of the circular vibrating tray. A plurality of annular grooves are formed on the upper surface of the circular vibrating tray, and at least one material removal hole and one discharge hole are formed in each annular groove; The width of the discharge hole is equal to that of the annular groove, the width of the material removal hole is smaller than that of the annular groove, a limiting slope is provided at the upper edge of the side of the discharge hole away from the material removal hole, two limiting bumps are fixedly arranged inside the discharge hole, and the two limiting bumps are arranged in a diagonal layout. A guide pipe is fixedly connected to the bottom of the discharge hole, and a pull-out pipe that can be pulled up and down is provided on the guide pipe; The main shaft of the rotating motor extends into the circular vibrating tray, and at least one rotating brush is installed on the main shaft.

[0006] Put the corn seeds into the circular vibrating tray. Under the vibration of the vibration motor, the corn seeds enter the annular groove. The rotating motor drives the rotating brush to rotate, and the rotating brush drives the corn seeds to continuously advance along the annular groove. The corn seeds first pass through the material removal hole. The width of the material removal hole is smaller than that of the annular groove. The corn seeds with smaller size will fall from the material removal hole, and the corn seeds with larger size cannot enter the annular groove. In this way, both the smaller and larger corn seeds can be removed, and only the medium-sized corn seeds are selected, so as to avoid the influence of inconsistent seed sizes on the germination and growth of seeds as much as possible. After the corn seeds pass through the material removal hole and approach the discharge hole, since the width of one end of the corn seed embryo is relatively smaller than that of the other end, when the corn seed embryo faces the side of the discharge hole, the corn seed can directly fall into the culture medium in the culture dish, and finally the culture dish is placed in the incubator for cultivation. In the process of selecting and cultivating corn seeds in the prior art, the cultivation device of the present invention can control the direction of the corn seeds placed in the culture medium of the culture dish. Compared with the current method of controlling the direction of corn seeds by pure manual operation, the labor intensity is greatly reduced, the efficiency is improved, and the direction control is more accurate.

[0007] Further preferably, the material removal hole is located at the middle position in the width direction of the annular groove. This can prevent some of the smaller-sized corn seeds that should have been eliminated from passing over the material removal hole.

[0008] Further preferably, the upper edge of the side of the material removal hole away from the discharge hole is in a rounded shape, which is convenient for the smaller-sized corn seeds that should be eliminated to smoothly slide into the material removal hole.

[0009] Further preferably, it further includes a tray, and culture dishes with a quantity adapted to the discharge holes are placed on the tray. After the corn seeds enter the culture medium, it is convenient for the operator to hold the tray and put multiple culture dishes into the incubator at one time.

[0010] Further preferably, a disc is installed on the main shaft of the rotating motor, the lower end surface of the disc is attached to the upper end surface of the circular vibrating tray, and the rotating brush includes a short rod and a long rod that are detachably connected together. The bottom of the long rod is covered with bristles, and the short rod is detachably installed on the disc. This is convenient for replacing and adjusting the rotating brush. For example, if it is found that the height of the bristles is not appropriate during use, the height can be adjusted.

[0011] The present invention also provides a method for cultivating corn seeds, comprising the following steps: S1: Disinfect corn seeds; S2: Put the sterilized corn seeds into a circular vibrating feed tray; S3: Turn on the vibration motor, which vibrates the corn seeds in the circular vibration tray. The rotating motor drives the rotating brush to rotate, and the corn seeds are screened, and the small and large corn seeds are eliminated; S4: Medium-sized corn seeds fall from the discharge hole. When falling, the seeds with the endosperm close to the discharge hole pass through the discharge hole and then approach the limiting slope. Under the action of gravity, the seeds slide along the limiting slope and fall from the discharge hole. S5: The corn seeds fall into the culture dish, and finally the culture dish is placed in an incubator for cultivation.

[0012] By using the cultivation method of the present invention, corn seeds can be placed in the culture medium in the culture dish with the embryo facing downward, and then placed in the culture box for cultivation, which can avoid the influence of the direction of the corn seeds on the germination and growth, so as to understand the influence of adjusting indicators such as temperature, humidity, and light intensity on the germination and growth of different varieties of corn seeds.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The corn seeds are placed in a circular vibrating feed tray. Under the vibration of the vibration motor, the corn seeds enter the annular groove. The rotating motor drives the rotating brush to rotate. The rotating brush drives the corn seeds to continuously advance along the annular groove. The corn seeds first pass through the picking hole. The width of the picking hole is smaller than the annular groove. The corn seeds with smaller head size will fall from the picking hole. The corn seeds with larger head size cannot enter the annular groove. The corn seeds with smaller and larger sizes can be removed. Only medium-sized corn seeds are selected to avoid the influence of different seed sizes on seed germination and growth. After the corn seeds pass through the picking hole, they are close to the discharge hole. Since the width of one end of the corn seed embryo is relatively smaller than the other end, when the corn seed embryo faces one side of the discharge hole, the corn seeds can directly fall into the culture medium in the culture dish. Finally, the culture dish is placed in the incubator for cultivation. In the selection and cultivation process of corn seeds in the prior art, the cultivation device of the present invention can control the direction in which the corn seeds are placed in the culture dish culture medium. Compared with the current control of the direction of the corn seeds by pure manual operation, the labor intensity is greatly reduced, the efficiency is improved, and the direction control is more accurate.

[0014] Using the cultivation method of the present invention, corn seeds can be placed in the culture medium in the culture dish with the seed embryos facing downwards, and then placed in an incubator for cultivation, which can avoid the influence of the direction of corn seeds on germination and growth, so as to learn about the influence of adjusting indicators such as temperature, humidity, and light intensity on the germination and growth of different varieties of corn seeds.

Detailed Embodiments

[0026] The following further describes the detailed embodiments of the present invention with reference to the accompanying drawings.

[0027] As Figures 1 to 9 shown, a cultivation device for corn seeds includes a screening mechanism for screening corn seeds and a culture dish 12, and further includes an incubator. The screening mechanism includes a base 1. A rotating motor 2 is installed at the center of the bottom of the base 1. The bottom of a circular vibrating tray 3 is installed on the base 1 through two support frames 9. The circular vibrating tray 3 is provided with a vibrating motor 8 at the bottom. A plurality of annular grooves 4 are formed on the upper surface of the circular vibrating tray 3. At least one material removal hole 5 and one discharge hole 6 are formed in each annular groove 4; The width of the discharge hole 6 is equal to the width of the annular groove 4. The width of the material removal hole 5 is smaller than the width of the annular groove 4. A limiting slope 16 is provided at the upper edge of the side of the discharge hole 6 away from the material removal hole 5. Two limiting convex blocks 15 are fixedly arranged inside the discharge hole 6. The two limiting convex blocks 15 are arranged in a diagonal layout. A guide pipe 13 is fixedly connected to the bottom of the discharge hole 6. A drawable pipe 14 that can be pulled up and down is provided on the guide pipe 13; The main shaft of the rotating motor 2 extends into the circular vibrating tray 3, and at least one rotating brush 7 is installed on the main shaft.

[0028] Put the corn seeds into the circular vibrating tray 3. Under the vibration of the vibrating motor 8, the corn seeds enter the annular groove 4. The rotating motor 2 drives the rotating brush 7 to rotate, and the rotating brush 7 drives the corn seeds to continuously move forward along the annular groove 4. The corn seeds first pass through the material removal hole 5. The width of the material removal hole 5 is smaller than that of the annular groove 4. The corn seeds with smaller size will fall from the material removal hole 5. The corn seeds with larger size cannot enter the annular groove 4. In this way, both the smaller and larger sized corn seeds can be removed, and only the medium-sized corn seeds are selected, thus minimizing the impact of inconsistent seed sizes on seed germination and growth. After the corn seeds pass through the material removal hole 5 and approach the discharge hole 6, since one end of the embryo of the corn seed is relatively narrower than the other end, when the embryo of the corn seed faces the side of the discharge hole 6, the corn seeds can directly fall into the culture medium in the culture dish 12. Finally, the culture dish 12 is placed into the incubator for cultivation. In the process of selecting and cultivating corn seeds in the prior art, the cultivation device of the present invention can control the direction of the corn seeds placed in the culture medium of the culture dish 12. Compared with the current method of controlling the direction of corn seeds through pure manual operation, the labor intensity is greatly reduced, the efficiency is improved, and the direction control is more accurate.

[0029] Among them, the material removal hole 5 is located at the middle position in the width direction of the annular groove 4, and the upper edge of the side of the material removal hole 5 away from the discharge hole 6 is in a rounded shape. This can prevent some relatively small-sized corn seeds that should have been eliminated from passing over the material removal hole 5, and at the same time facilitate the relatively small-sized corn seeds that should be eliminated to smoothly slide into the material removal hole 5.

[0030] Among them, it further includes a tray 11, and culture dishes 12 with a quantity adapted to the discharge holes 6 are placed on the tray 11. When the corn seeds enter the culture medium, it is convenient for the operator to hold the tray 11 and put multiple culture dishes 12 into the incubator at one time.

[0031] Among them, a disc is installed on the main shaft of the rotating motor 2, and the lower end surface of the disc is in contact with the upper end surface of the circular vibrating tray 3. The rotating brush 7 includes a short rod 17 and a long rod 18 that are detachably connected together. The bottom of the long rod 18 is covered with bristles 19, and the short rod 17 is detachably installed on the disc. This is convenient for replacing and adjusting the rotating brush 7. For example, if it is found that the height of the bristles 19 is not appropriate during use, the height can be adjusted.

[0032] The present invention also provides a cultivation method for corn seeds, including the following steps: S1: Disinfect the corn seeds; S2: Put the disinfected corn seeds into the circular vibrating tray 3; S3: Prepare a sufficient number of culture dishes 12, and place the culture medium in each culture dish 12; S4: Place the culture dishes 12 on the tray 11, bring the tray 11 with multiple culture dishes 12 under the pull-out tube 14, and then pull down the pull-out tube 14 to insert the lower part of the pull-out tube 14 into the culture medium; S5: Turn on the vibration motor 8, the vibration motor 8 vibrates the corn seeds in the circular vibrating tray 3, the rotating motor 2 drives the rotating brush 7 to rotate, and the corn seeds are screened, and the relatively small-sized and relatively large-sized corn seeds are both eliminated; S6: The medium-sized corn seeds fall from the discharge hole 6. When falling, the seeds on the side of the endosperm close to the discharge hole 6 pass through the discharge hole 6, and then are close to the limiting slope 16. The seeds slide down along the limiting slope 16 under the action of gravity and fall from the discharge hole 6; S7: The corn seeds fall into the culture dishes 12, and finally the culture dishes 12 are put into the incubator for cultivation.

[0033] S8: Change and adjust a certain index among the indexes such as temperature, humidity, and light intensity, while keeping other indexes unchanged, and then the influence of each index on the germination and growth of different varieties of corn seeds can be learned one by one.

[0034] Using the cultivation method of the present invention, corn seeds can be placed in the culture medium in the culture dish 12 with the seed embryos facing downwards, and then placed in an incubator for cultivation, which can avoid the influence of the direction of corn seeds on germination and growth, so as to be able to learn about the influence of adjusting indicators such as temperature, humidity, and light intensity on the germination and growth of different varieties of corn seeds.
