Description

Technical Field

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

[0002] Corn is highly tolerant to drought, cold, and infertility, and has excellent environmental adaptability. As a high-yield grain crop, corn is an important source of feed for animal husbandry, aquaculture, and other industries. Numerous varieties of corn seeds are commercially available, and to select superior varieties, incubators, commonly used in breeding laboratories, are required. These incubators can adjust temperature, humidity, light intensity, and other parameters as needed, all of which affect the germination and growth of corn seeds in the culture dish. Another important factor is the orientation of the corn seeds in the culture medium. Generally, when the embryo is placed downward, corn seeds germinate faster, have a higher germination index and vitality index, and the seedlings grow faster and healthier.

[0003] Specifically, when selecting and cultivating different varieties of corn seeds, if one wants to know the impact 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. However, the placement of the corn seeds in the culture medium is difficult to control, and operators need to use handheld tweezers to place the corn seeds one by one in the culture medium according to the required direction. This method is labor-intensive and inefficient, and the placement direction of the corn seeds is difficult to ensure accuracy. In the prior art, there is no such device or equipment for controlling the direction in which the seeds are placed in the culture medium during seed selection and cultivation. Summary of the Invention

[0004] The purpose of the present invention is to solve the technical problems in the prior art that the direction in which corn seeds are placed in the culture medium can only be controlled by purely manual operation, which is labor-intensive, inefficient, and difficult to ensure the accuracy of the direction, and to provide a corn seed cultivation device and method.

[0005] The present invention is achieved through the following technical solutions:

[0006] That is, a corn seed cultivation device, comprising a screening mechanism for screening corn seeds and a culture dish, and also comprising an incubator, wherein the screening mechanism comprises a base, a rotating motor and a circular vibrating material tray are mounted on the base, a vibrating motor is mounted on the bottom of the circular vibrating material tray, a plurality of annular grooves are formed on the upper surface of the circular vibrating material tray, and each annular groove has at least one material removal hole and one material discharge hole;

[0007] The width of the discharge hole is equal to the width of the annular groove, and the width of the pick hole is smaller than the width of the annular groove. A limiting slope is provided at the upper edge of the discharge hole away from the pick hole. Two limiting protrusions are fixedly provided inside the discharge hole. The two limiting protrusions are arranged diagonally. A material guide pipe is fixedly connected to the bottom of the discharge hole, and a pulling pipe that can be pulled up and down is provided on the material guide pipe.

[0008] The main shaft of the rotating motor extends into the circular vibrating material tray, and at least one rotating brush is installed on the main shaft.

[0009] The invention discloses a method for controlling the corn seed seeding process by a circular vibrating feed tray. The method comprises the following steps: placing corn seeds in a circular vibrating feed tray, and vibrating the feed tray to a vibrating motor, wherein the corn seeds enter the annular groove, and 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 picking hole, and the picking hole width is smaller than the annular groove. The corn seeds with smaller head size will fall from the picking hole, and the corn seeds with larger head size cannot enter the annular groove. Thus, both smaller and larger corn seeds are removed, and 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 smaller than that of the other end, when the corn seed embryo is toward the discharge hole side, the corn seed can directly fall into the culture medium in the culture dish, and finally the culture dish is placed in an incubator for cultivation. In the prior art corn seed selection and cultivation process, 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 method of controlling the direction of the corn seeds by purely manual operation, the labor intensity is greatly reduced, the efficiency is improved, and the direction control is more accurate.

[0010] More preferably, the material removal hole is located in the middle of the width direction of the annular groove, so as to prevent some smaller corn seeds that should have been eliminated from passing over the material removal hole.

[0011] Further preferably, the upper edge of the removal hole away from the discharge hole is rounded, so that the smaller corn seeds to be eliminated can slide smoothly into the removal hole.

[0012] More preferably, a tray is included, and culture dishes having the same number as the discharge hole 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.

[0013] Further preferably, a disc is mounted on the main shaft of the rotating motor, the lower end of the disc being in contact with the upper end of the circular vibrating material disc, and the rotating brush comprises a short rod and a long rod that are detachably connected together, the bottom of the long rod being covered with bristles, and the short rod being detachably mounted on the disc. This facilitates replacement and adjustment of the rotating brush, for example, if the height of the bristles is not suitable during use, the height can be adjusted.

[0014] The present invention also provides a method for cultivating corn seeds, comprising the following steps:

[0015] S1: Disinfect corn seeds;

[0016] S2: Place the sterilized corn seeds into a circular vibrating feed tray;

[0017] 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.

[0018] 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.

[0019] S5: The corn seeds fall into the culture dish, and finally the culture dish is placed in the incubator for cultivation.

[0020] 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 incubator for cultivation. This can avoid the influence of the direction of the corn seeds on germination and growth, so that the influence of adjusting indicators such as temperature, humidity, and light intensity on the germination and growth of different varieties of corn seeds can be understood.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The invention discloses a method for controlling the corn seed seeding process by a circular vibrating feed tray. The method comprises the following steps: placing corn seeds in a circular vibrating feed tray, and vibrating the feed tray to a vibrating motor, wherein the corn seeds enter the annular groove, and 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 picking hole, and the picking hole width is smaller than the annular groove. The corn seeds with smaller head size will fall from the picking hole, and the corn seeds with larger head size cannot enter the annular groove. Thus, both smaller and larger corn seeds are removed, and 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 smaller than that of the other end, when the corn seed embryo is toward the discharge hole side, the corn seed can directly fall into the culture medium in the culture dish, and finally the culture dish is placed in an incubator for cultivation. In the prior art corn seed selection and cultivation process, 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 method of controlling the direction of the corn seeds by purely manual operation, the labor intensity is greatly reduced, the efficiency is improved, and the direction control is more accurate.

DETAILED DESCRIPTION

[0035] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] like Figures 1 to 9 The corn seed cultivation device shown includes a screening mechanism for screening corn seeds and a culture dish 12, and also includes an incubator. The screening mechanism includes a base 1, a rotating motor 2 is installed at the bottom center of the base 1, and a circular vibrating feed tray 3 is installed on the base 1 through two support frames 9. The circular vibrating feed tray 3 has a vibration motor 8 installed at the bottom. The upper surface of the circular vibrating feed tray 3 is provided with a plurality of annular grooves 4, each of which has at least one material removal hole 5 and a material discharge hole 6.

[0037] The width of the discharge hole 6 is equal to the width of the annular groove 4, and the width of the pick hole 5 is smaller than the width of the annular groove 4. A limiting slope 16 is provided at the upper edge of the discharge hole 6 away from the pick hole 5. Two limiting protrusions 15 are fixedly provided inside the discharge hole 6. The two limiting protrusions 15 are arranged diagonally. A guide tube 13 is fixedly connected to the bottom of the discharge hole 6, and a pulling tube 14 that can be pulled up and down is provided on the guide tube 13;

[0038] The main shaft of the rotating motor 2 extends into the circular vibrating material tray 3, and at least one rotating brush 7 is installed on the main shaft.

[0039] The corn seeds are placed in the circular vibrating feed tray 3. Under the vibration action of the vibration 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 advance along the annular groove 4. The corn seeds first pass through the picking hole 5. The width of the picking hole 5 is smaller than the annular groove 4. The smaller corn seeds will fall from the picking hole 5, and the larger corn seeds cannot enter the annular groove 4. Both the smaller and larger corn seeds can be removed, and only medium-sized corn seeds are selected to avoid the influence of different seed sizes on seed germination and growth. After passing through the picking hole 5, the corn seeds are close to the discharge hole 6. Since the width of one end of the corn seed embryo is smaller than the other end, when the corn seed embryo is toward the side of the discharge hole 6, the corn seed can directly fall into the culture medium in the culture dish 12. Finally, the culture dish 12 is placed in the incubator for cultivation. In the prior art process of corn seed selection and cultivation, the cultivation device of the present invention can control the direction in which the corn seeds are placed in the culture medium of the culture dish 12. Compared with the current method of controlling the direction of the corn seeds by pure manual operation, it greatly reduces labor intensity, improves efficiency, and makes direction control more precise.

[0040] The removal hole 5 is located in the middle of the annular groove 4 in the width direction, and the upper edge of the removal hole 5 on the side away from the discharge hole 6 is rounded. This can prevent some small corn seeds that should be eliminated from passing over the removal hole 5, while also allowing the small corn seeds that should be eliminated to slide smoothly into the removal hole 5.

[0041] Among them, it also includes a tray 11, and culture dishes 12 of the same number as the discharge holes 6 are placed on the tray 11. After 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.

[0042] The main shaft of the rotating motor 2 is mounted with a disc, the lower end of which contacts the upper end of the circular vibrating material disc 3. The rotating brush 7 comprises a short rod 17 and a long rod 18 that are detachably connected. The bottom of the long rod 18 is covered with bristles 19, and the short rod 17 is detachably mounted on the disc. This facilitates replacement and adjustment of the rotating brush 7. For example, if the height of the bristles 19 is found to be unsuitable during use, the height can be adjusted.

[0043] The present invention also provides a method for cultivating corn seeds, comprising the following steps:

[0044] S1: Disinfect corn seeds;

[0045] S2: Place the sterilized corn seeds into the circular vibrating feed tray 3;

[0046] S3: Prepare enough culture dishes 12 and place culture medium in each culture dish 12;

[0047] S4: Place the culture dishes 12 on the tray 11, place the tray 11 with the multiple culture dishes 12 directly under the pull-out tube 14, and then pull the pull-out tube 14 downward to insert the lower part of the pull-out tube 14 into the culture medium;

[0048] S5: Turn on the vibration motor 8, which vibrates the corn seeds in the circular vibration tray 3. The rotation motor 2 drives the rotating brush 7 to rotate, and the corn seeds are screened, and the small and large corn seeds are eliminated;

[0049] S6: The medium-sized corn seeds fall from the discharge hole 6. When falling, the seeds on the side of the endosperm closer to the discharge hole 6 pass through the discharge hole 6 and then approach the limiting slope 16. Under the action of gravity, the seeds slide along the limiting slope 16 and fall from the discharge hole 6.

[0050] S7: The corn seeds fall into the culture dish 12, and finally the culture dish 12 is placed in an incubator for cultivation.

[0051] S8: By changing one of the indicators such as temperature, humidity, light intensity, etc., while keeping the other indicators unchanged, we can know the impact of each indicator on the germination and growth of different varieties of corn seeds.

[0052] Using the cultivation method of the present invention, corn seeds can be placed in the culture medium in the culture dish 12 with the embryo facing downward, and then placed in the incubator 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.
