Description

Technical Field

[0001] This utility model belongs to the field of crop disease control equipment, specifically a corn ear rot inoculator. Background Technology

[0002] Corn ear rot, also known as corn kernel rot, corn scab, or corn dry rot, is a disease caused by a variety of pathogens. It mainly affects the ears and kernels of corn. The top or middle of the affected ears will turn discolored and develop a pink, blue-green, blackish-gray, dark brown, or yellowish-brown mold layer. It is one of the important diseases in the later stages of corn growth.

[0003] Therefore, equipment is needed for inoculating corn ear rot pathogens. Inoculation devices for corn ear rot are mainly used in the following areas:

[0004] 1. Disease resistance breeding research: Researchers can use inoculation devices to inoculate different maize varieties with pathogens to assess their disease resistance, which helps to screen disease-resistant varieties and improve maize yield and quality.

[0005] 2. Disease control practices: Farmers and agricultural technicians can use inoculation devices to conduct disease control practices in the field. Through the inoculation device, they can evenly inoculate pathogen spores onto corn plants, thereby simulating the disease occurrence process and providing strong support for subsequent disease control.

[0006] 3. Teaching and Research: The inoculation device can also be used in teaching and research. Through demonstrations and hands-on practice, students and researchers can better understand the pathogenesis and control methods of corn ear rot.

[0007] While traditional injection inoculation methods can be used to inoculate corn, the inoculation results vary depending on the specific pathogen causing corn ear rot. In some cases, the inoculation is done on the silks, while in others it is done on the corn cob, and the amount of inoculation also varies. Therefore, poor inoculation results are often encountered. Utility Model Content

[0008] To address the aforementioned technical problems, this utility model provides a corn ear rot inoculator, thereby resolving the issue of poor inoculation effectiveness in the corn inoculation process using existing inoculators.

[0009] A corn ear rot inoculator includes an inoculation tray with a rotatably connected support column inside. The bottom of the support column has an inoculation cylinder containing a spore suspension. The inoculation tray has positioning holes arranged in a ring around the support column.

[0010] It also includes injection needles, which are connected to the positioning holes and the diameter of each injection needle is different. The support column has an extended infusion tube inside, which communicates with the inoculation tube. The other end of the infusion tube has an injection interface that is inserted into the positioning hole and communicates with the injection needle.

[0011] Preferably, the bottom of the support column is fixedly connected to the inoculation cylinder, the inoculation cylinder is provided with an injection solution receiving tank, the spore suspension is placed in the injection solution receiving tank, and the inoculation cylinder is provided with a movable push rod, the push rod pushes the spore suspension into the support column.

[0012] Preferably, the injection solution container is provided with a movable shaking ball, the annular wall of the inoculation tube is provided with an injection solution inlet, and the injection solution inlet is provided with a sealing plug.

[0013] Preferably, the number of positioning holes on the inoculation tray is not less than three, the bottom of the injection needle is provided with a locking ring that is fixedly connected, the outer wall of the locking ring has external threads, the locking ring is locked in the positioning hole by the threads, and the top of the locking ring is provided with a sealing ring that fits against the outer wall of the inoculation tray.

[0014] Preferably, the infusion tubing is flexible and retractable, the injection port is a component made of rigid material, and a second sealing ring is provided on the outer wall of the injection port. After the injection port is inserted into the positioning hole, the second sealing ring is also located in the positioning hole.

[0015] Preferably, the bottom wall of the inoculation tray is provided with a magnetic chuck one around each of the positioning holes, and the outer wall of the injection interface is provided with a magnetic chuck two below the sealing ring two, and the magnetic chuck one and the magnetic chuck two are attracted to each other.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model sets different numbers of injection needles on the inoculation tray, and the diameter of each injection needle is different. The injection interface is inserted into the positioning hole and communicates with the injection needle. The spore suspension can be transported into the injection needle through the inoculation tube through the inoculation tube, thereby transporting the spore suspension into the corn.

[0018] When it is necessary to change the injection needle, pull the injection port out of the positioning hole. The magnetic chuck one and magnetic chuck two will no longer be attracted. Rotate the inoculation tray to insert the injection port into the positioning hole at different positions. Smaller needles can produce more precise inoculation points and are suitable for situations requiring localized and precise inoculation. Larger needles can release the inoculation material more quickly and are suitable for situations with a larger inoculation area. Thus, different injection needles can be selected for inoculation according to the condition of the corn, optimizing the inoculation effect of the corn.

[0019] 2. This utility model designs multiple injection needles so that when different injection solutions are placed in the inoculation tube, rotating the inoculation tray allows different injection solutions to enter the corresponding injection needles, thus avoiding the injection needles from being contaminated with other injection solutions.

Detailed Implementation

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0028] As attached Figure 1 To be continued Figure 5 As shown:

[0029] Example 1: This utility model provides a corn ear rot inoculator, including an inoculation tray 1, a rotatably connected support column 2 inside the inoculation tray 1, an inoculation cylinder 3 at the bottom of the support column 2 containing a spore suspension, and positioning holes 4 arranged in a ring around the support column 2.

[0030] It also includes an injection needle 5, which is connected to the positioning hole 4 and the diameter of the hole in each injection needle 5 is different. The support column 2 has an extended infusion tube 6 inside, which is interconnected with the inoculation tube 3. The other end of the infusion tube 6 is provided with an injection interface 17 that is inserted into the positioning hole 4 and interconnected with the injection needle 5.

[0031] It should be noted that by setting different numbers of injection needles 5 on the inoculation tray 1, the diameter of each injection needle 5 is different, the injection interface 17 is inserted into the positioning hole 4 and communicates with the injection needle 5, and the spore suspension can be delivered to the injection needle 5 through the inoculation tube 6 through the inoculation tube 3, thereby delivering the spore suspension into the corn.

[0032] When it is necessary to replace the injection needle 5, pull the injection interface 17 out of the positioning hole 4. The magnetic chuck 15 and magnetic chuck 16 will no longer be attracted. Rotate the inoculation tray 1 so that the injection interface 17 is inserted into the injection needle 5 at different positions. Smaller needles can produce finer inoculation points, which is suitable for situations requiring precise local inoculation. Larger needles can release the inoculation material more quickly, which is suitable for situations with a larger inoculation area. Thus, different injection needles 5 can be selected for inoculation according to the condition of the corn, thereby optimizing the inoculation effect on the corn.

[0033] In this embodiment, the bottom of the support column 2 is fixedly connected to the inoculation cylinder 3. The inoculation cylinder 3 is provided with an injection liquid receiving tank 7, and the spore suspension is placed in the injection liquid receiving tank 7. The inoculation cylinder 3 is provided with a movable push rod 8, which pushes the spore suspension into the support column 2.

[0034] It should be noted that the injection solution receiving tank 7 is designed to store the spore suspension inside the injection solution receiving tank 7. The push rod 8 is movably sealed inside the injection solution receiving tank 7. Thus, when the push rod 8 is pushed forward, the spore suspension moves inside the injection solution receiving tank 7 into the support column 2, and the spore suspension is delivered into the infusion tube 6.

[0035] In this embodiment, the injection solution receiving tank 7 is provided with a movably connected shaking ball 9, and the annular wall of the inoculation cylinder 3 is provided with an injection solution inlet 10, and the injection solution inlet 10 is provided with a sealing plug 11.

[0036] It should be noted that the shaking ball 9 can roll in the injection solution container 7. After the spore suspension is placed in the injection solution container 7, the shaking ball 9 can be continuously rolled in the injection solution container 7 by shaking the inoculation cylinder 3, so as to avoid the spore suspension from settling in the injection solution container 7 and make the spore suspension enter the infusion tube 6 more easily.

[0037] The sealing plug 11 is movably connected inside the injection inlet 10. The injection inlet 10 can deliver the spore suspension back into the inoculation cylinder 3 when the amount of spore suspension is insufficient. The sealing plug 11 can seal it to ensure that the spore suspension does not flow out from the injection inlet 10.

[0038] In this embodiment, there are no fewer than three positioning holes 4 on the inoculation tray 1. The bottom of the injection needle 5 is provided with a locking ring 12 that is fixedly connected. The outer wall of the locking ring 12 has external threads. The locking ring 12 is locked in the positioning hole 4 by means of threads. The top of the locking ring 12 is provided with a sealing ring 13 that fits against the outer wall of the inoculation tray 1.

[0039] It should be noted that the locking ring 12 is fixedly connected to the tail end of the injection needle 5. The locking ring 12 is locked in the positioning hole 4 by means of threads. On the one hand, the injection needle 5 can be fixed in the positioning hole 4. On the other hand, the injection needle 5 is designed to be detachable, so that after the corn is inoculated, the injection needle 5 can be removed from the spore suspension plate, which facilitates the disinfection of the injection needle 5.

[0040] A sealing ring 13 is provided on the outer wall of the locking ring 12. After the injection needle 5 enters the positioning hole 4 and is fixed by the locking ring 12, the sealing ring 13 fits into the inoculation tray 1, thereby improving the sealing between the locking ring 12 and the inoculation tray 1, and preventing the spore suspension from leaking out of the locking ring 12.

[0041] In this embodiment, the infusion tube 6 is flexible and retractable, and the injection interface 17 is a component made of rigid material. A sealing ring 14 is provided on the outer wall of the injection interface 17. After the injection interface 17 is inserted into the positioning hole 4, the sealing ring 14 is also located in the positioning hole 4.

[0042] It should be noted that designing the infusion tube 6 as flexible allows the injection port 17 to be pulled out of the positioning hole 4, while designing the injection port 17 as rigid ensures the stability of the injection port 17 after it is inserted into the positioning hole 4, preventing it from easily coming out of the positioning hole 4.

[0043] In this embodiment, a magnetic chuck 15 is provided on the bottom wall of the inoculation tray 1 and around the hole of each positioning hole 4, and a magnetic chuck 16 is provided on the outer wall of the injection interface 17 and below the sealing ring 14. The magnetic chuck 15 and the magnetic chuck 16 attract each other.

[0044] In the above embodiment, magnetic chuck 15 is fixedly connected to the bottom wall of the inoculation tray 1, and magnetic chuck 2 16 is fixedly connected to the outer wall of the injection port 17. After the injection port 17 enters the positioning hole 4, magnetic chuck 15 and magnetic chuck 2 16 attract each other, so that under normal circumstances, the injection port 17 can be fixedly connected in the positioning hole 4 and connected to the injection needle 5.

[0045] The method of the above embodiment: When it is necessary to inoculate corn with pathogens, there are evenly spaced positioning holes 4 on the inoculation tray 1. The inoculation tray 1 and the injection needle 5 are separated. The locking ring 12 on the injection needle 5 is rotated and locked into the positioning hole 4. The sealing ring 13 is attached to the inoculation tray 1 to ensure the sealing. Multiple injection needles 5 with different diameters are placed in the inoculation tray 1.

[0046] The injection port 17 is rotated and inserted into the positioning hole 4 from below the inoculation tray 1. At this time, the sealing ring 14 on the injection port 17 will enter the positioning hole 4 to be fixed. The magnetic chuck 15 and the magnetic chuck 16 are attracted to each other, ensuring the stability of the injection port 17.

[0047] Push the push rod 8 forward to press the spore suspension in the injection container 7 into the support column 2. The support column 2 has an infusion tube 6 inside, which comes out from the injection needle 5 through the infusion interface. The injection needle 5 is inserted into the corn ear to achieve inoculation.

[0048] When it is necessary to change to a different injection needle 5, separate the magnetic chuck 15 from the magnetic chuck 2 16, and move the injection port 17 downwards to disengage it from the positioning hole 4. The inoculation tray 1 rotates and connects to the support column 2. After rotating to the appropriate injection needle 5, reinsert the injection port 17 into the positioning hole 4. The top of the injection port 17 fits against the bottom of the locking ring 12. Smaller needles can produce finer inoculation points, which is suitable for situations requiring precise local inoculation; while larger needles can release spore suspension material more quickly, thus being suitable for larger areas and optimizing the inoculation effect on corn.

[0049] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
