Description

Technical Field

[0001] This invention relates to the field of maize disease resistance research, and in particular to a tool for applying ointment to wounds after drilling holes in maize stalks. Background Technology

[0002] Research on maize disease resistance is a broad and in-depth field, mainly focusing on resistance mechanisms against major maize diseases, screening of resistant varieties, and genetic improvement. One research project in this field involves directly drilling holes in maize stalks and inoculating them with fungal colonies.

[0003] When drilling holes in corn stalks for inoculation, the holes are usually drilled at the lower end of the stalk, close to the ground. After inoculation, small wounds appear on the corn stalk, accelerating water evaporation and potentially causing further damage from small insects. Therefore, to protect the stalk and ensure successful observation and research of the inoculated corn, current techniques typically involve applying an ointment, such as petroleum jelly, to the wound. This is usually done using a cotton swab. However, since the experiment involves many plants, this method is inefficient and cumbersome due to prolonged bending. Summary of the Invention

[0004] To address the technical problems mentioned in the background art, the present invention provides a tool for applying ointment to wounds after drilling holes in corn stalks.

[0005] This invention is achieved using the following technical solution: a tool for applying ointment to wounds after drilling holes in corn stalks, comprising a housing, wherein the housing contains:

[0006] A connecting shaft is movably disposed inside the housing, with one end extending out of the housing, and an applicator is fixedly connected to one end of the connecting shaft;

[0007] A drive mechanism is disposed inside the housing and is used to drive the connecting shaft and the coating part to reciprocate.

[0008] The medicine box is connected inside the shell, and a lifting mechanism is connected to the outside of the medicine box. The lifting mechanism is connected to a drive mechanism to drive the medicine box to move up and down.

[0009] Through the above technical solution, the drive mechanism can, on the one hand, drive the connecting shaft and the application part to reciprocate, controlling the application part to extend or retract into the shell. The application part can be a sponge. When the application part moves outside the shell, it can transfer the ointment onto it into the holes of the corn stalk. On the other hand, the drive mechanism, in conjunction with the lifting connecting mechanism, can simultaneously drive the medicine box to move up and down. When the application part is retracted into the shell, the medicine box is facing upwards, and the application part contacts the ointment inside the medicine box, transferring the ointment onto the application part (sponge). When the application part extends out of the shell and contacts the holes of the corn stalk, it can transfer the ointment onto the corn stalk. This protects the corn stalk, prevents it from rotting, and prevents insects from causing further damage to the small holes.

[0010] As a further improvement to the above solution, the connecting shaft is a threaded shaft, and the outer side of the connecting shaft is threadedly connected to a fixing sleeve. The fixing sleeve has an internal thread, and the fixing sleeve is fixedly connected to the housing.

[0011] Through the above technical solution, and with the cooperation of the fixed sleeve, the connecting shaft can rotate around its own axis during horizontal movement. Combined with the drive mechanism, the connecting shaft can rotate and move forward simultaneously.

[0012] As a further improvement to the above solution, the coating part is made of sponge and is fixedly connected to one end of the connecting shaft, while a connecting ball is fixedly connected to the other end of the connecting shaft.

[0013] Using the above technical solution, the sponge can easily absorb the ointment.

[0014] As a further improvement to the above solution, the driving mechanism includes:

[0015] The upper connecting plate has a cavity inside the housing and is slidably connected to the cavity. At the same time, a limiting ridge is fixedly provided on the inner wall of the cavity of the housing, and a limiting slot is provided on the upper connecting plate, so that the upper connecting plate can move along the direction of the limiting ridge.

[0016] A connector is fixedly connected to one side of the upper connecting plate, and is also sleeved on the outside of the connecting ball;

[0017] The control shaft is a threaded shaft that is rotatably mounted inside the housing. One end of the control shaft is connected to a motor, and the entire control shaft extends through the upper connecting plate.

[0018] With the above technical solution, when the motor drives the control shaft to rotate, it can drive the upper connecting plate to move horizontally. The upper connecting plate will then drive the connecting shaft to move horizontally.

[0019] As a further improvement to the above solution, the upper connecting plate is also provided with an installation port, and a spring rod is fixedly installed in the installation port.

[0020] As a further improvement to the above solution, the bottom of the medicine box is provided with a tray, and limit sliders are fixedly provided on both sides of the tray. At the same time, a limit groove is fixedly connected to the inner wall of the shell, and the limit sliders are slidably connected in the limit groove, so that the tray can move along the limit groove.

[0021] The above technical solution, with its limiting slider and limiting groove, provides limiting and guiding functions for the movement of the tray and medicine box.

[0022] As a further improvement to the above solution, the lifting connection mechanism includes:

[0023] A sliding plate is provided in the bottom of the housing, a sliding groove is provided, a sliding plate is slidably installed in the sliding groove, and an arc-shaped frame is fixedly connected to the sliding plate;

[0024] A support rod is fixedly connected to a support plate at its upper end and rotatably connected to a mounting plate at its lower end. A pulley is rotatably mounted on the mounting plate, with two pulleys arranged in a group, each group located on one side of the arc-shaped frame.

[0025] With the above technical solution, when the sliding plate and the arc-shaped frame move together, the two pulleys will engage with the arc-shaped frame. The arc-shaped frame will then drive the mounting plate and support plate to move up or down via the pulleys. Additionally, in actual use, a guide frame is fitted around the outside of the support rod. The guide frame is fixedly connected to the housing, and the support rod passes through the guide frame, allowing it to move only up and down along the guide frame. The support rod then drives the pallet to move up and down.

[0026] As a further improvement to the above solution, the lifting connection mechanism also includes a lower connecting plate, the upper end of which is inserted into the mounting port of the upper connecting plate, and the spring rod passes through the lower connecting plate. The other end of the lower connecting plate is fixedly connected to the sliding plate. A limit block is also provided inside the housing and on one side of the lower connecting plate.

[0027] As a further improvement to the above solution, a baffle is rotatably connected to one end of the housing near the coating part, and a magnetic snap fastener is provided between the baffle and the housing.

[0028] With the above technical solution, when the upper connecting plate moves, it will drive the lower connecting plate to move together. When the lower connecting plate contacts the limit block, it is blocked, and the upper connecting plate can continue to move. The lower connecting plate is blocked. The spring on the spring rod is compressed.

[0029] As a further improvement to the above solution, a handle is fixedly connected to the lower end of the housing, and a control button is installed on the handle. The control button is electrically connected to the drive mechanism.

[0030] The above technical solution allows for the forward and reverse rotation of the motor in the drive mechanism via two control buttons, thereby causing the motor to drive the control shaft to rotate in both directions.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] 1. This invention first uses a drive mechanism and connecting shaft to rotate and move the coating unit, applying the ointment to the inner wall of the small holes. This protects the holes on the corn stalk, preventing moisture loss and insects from further enlarging the wounds. This reduces the possibility of rotting of the corn stalk wounds and ensures successful observation of the inoculated microorganisms and their development.

[0033] 2. The present invention, through the cooperation of the lifting connection mechanism and the driving mechanism, can drive the medicine box to move up and down, so that the application part will automatically pick up the ointment in the medicine box during the movement, thus facilitating continuous operation of the application part, improving efficiency, and eliminating the need for the user to directly contact the ointment.

[0043] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0044] Example 1:

[0045] Please refer to Figures 1-4 This embodiment provides a tool for applying ointment to wounds after drilling holes in corn stalks. The tool includes a housing 1, within which a connecting shaft 2 is disposed. The connecting shaft 2 is a threaded shaft, and a fixing sleeve 4 is fitted onto the outer side of the connecting shaft 2. The fixing sleeve 4 is fixedly connected to the housing 1, and an internal thread is provided inside the fixing sleeve 4, connecting the connecting shaft 2 and the fixing sleeve 4 in a threaded connection.

[0046] To facilitate the application of ointment to the drilled wound, an application part 3 is connected to one end of the connecting shaft 2. In this embodiment, the application part 3 is made of sponge material. In actual operation, the sponge can be wrapped around a thin rod (not shown in the figure), and the thin rod can be fixedly connected to one end of the connecting shaft 2. The sponge material of the application part 3 makes it easy to apply petroleum jelly and transfer the ointment to the corn stalk. In addition, a connecting ball 5 is fixedly connected to the other end of the connecting shaft 2.

[0047] To facilitate the control of the connecting shaft 2 and the application part 3 extending out of the housing 1 for applying ointment to wounds on corn stalks, a drive mechanism 6 is provided. Specifically, the drive mechanism 6 includes an upper connecting plate 61. Firstly, a cavity is formed inside the housing 1, and a limiting ridge 66 is provided on the cavity wall. Limiting slots 62 are provided on both sides of the upper connecting plate 61. The upper connecting plate 61 is engaged with the limiting ridge 66 through the limiting slots 62, thus the upper connecting plate 61 can only move along the direction of the limiting ridge 66. A connecting member 63 is inherently located on one side above the upper connecting plate 61, and the connecting member 63 is also sleeved on the outside of the aforementioned connecting ball 5.

[0048] The drive mechanism 6 also includes a control shaft 64 and a motor 65. The control shaft 64 is also a threaded shaft, which is rotatably mounted in the housing 1 via a bearing seat. One end of the control shaft 64 is connected to the motor 65. The control shaft 64 extends through the upper connecting plate 61. When the motor 65 drives the control shaft 64 to rotate, it controls the upper connecting plate 61 to move along the limiting ridge 66 (in the direction of the axis of the control shaft 64).

[0049] In summary, when the upper connecting plate 61 moves axially along the control shaft 64, it will drive the connecting shaft 2 to move together through the connecting piece 63 and the connecting ball 5. Since the connecting shaft 2 and the fixed sleeve 4 are connected by threads, rotation still occurs when the connecting shaft 2 moves. Because the connecting ball 5 rotates within the connecting piece 63, it will not affect the movement of the connecting piece 63 or the upper connecting plate 61.

[0050] In addition, for ease of operation, a handle 12 is fixedly connected to the bottom of the housing 1, allowing the user to hold it with one hand. Two control buttons 13 are installed on the handle 12, and the control buttons 13 are electrically connected to the motor 65 in the drive mechanism 6. The two control buttons 13 control the forward and reverse rotation of the motor 65, respectively.

[0051] The implementation process and principle of the tool for applying ointment to wounds after drilling holes in corn stalks in this application embodiment are as follows:

[0052] by Figure 2 For example, the forward and reverse rotation of motor 65 is controlled by control button 13. When motor 65 drives control shaft 64 to rotate forward and reverse, the upper connecting plate 61 in drive mechanism 6 can drive connecting shaft 2 to move back and forth. When connecting shaft 2 moves to the left, it is retracted into housing 1; when it moves to the right, it extends out of housing 1. With the cooperation of fixing sleeve 4, connecting shaft 2 will also rotate around its own axis when it moves.

[0053] If the coating part 3 has ointment adhering to it, align one end of the shell 1 with the hole on the stem. As the connecting shaft 2 drives the coating part 3 to rotate and move to the right along the hole on the corn stalk, the coating part 3 enters the stem and rotates, quickly transferring the ointment to the inner wall of the hole. This allows the ointment to be applied to the wound left after drilling, thus protecting the wound and preventing subsequent insects from contacting it, reducing the risk of ulceration.

[0054] Conversely, controlling the connecting shaft 2 (applying part 3) to the left can cause the applicating part 3 to be retracted into the housing 1.

[0055] Example 2:

[0056] Please refer to Figures 5-8This embodiment, based on Embodiment 1, further improves upon the previous one by the following: Since the ointment needs to be applied to the application part 3 beforehand to complete the work, and the ointment is mostly a viscous paste (such as petroleum jelly), a medicine box 7 is provided inside the housing 1 and below the connecting shaft 2. The medicine box 7 contains the ointment.

[0057] To facilitate the application unit 3's quick application of ointment when retracted into the housing 1, a tray 8 is provided at the bottom of the medicine box 7, on which the medicine box 7 slides. Additionally, a lifting mechanism 9 is provided inside the housing 1, connected to the aforementioned drive mechanism 6, which simultaneously moves the medicine box 7 up and down. When the drive mechanism 6 retracts the application unit 3 into the housing 1, the lifting mechanism 9 simultaneously pushes the medicine box 7 upwards, allowing the application unit 3 to easily pick up the ointment within.

[0058] The lifting connection mechanism 9 is used to drive the medicine box 7 and the tray 8 to move up and down. In order for the tray 8 and the medicine box 7 to move up and down stably, dovetail-shaped limiting sliders 81 are fixedly connected to both sides of the tray 8, and limiting grooves 82 are fixedly connected to the corresponding positions on the inner wall of the housing 1. Figure 3 (See Chinese annotation). The limiting slider 81 is slidably installed in the limiting groove 82. Therefore, the cooperation between the limiting groove 82 and the limiting slider 81 provides limiting and guiding functions for the movement of the pallet 8.

[0059] In addition, the lifting connection mechanism 9 includes a sliding plate 91 and an arc-shaped frame 92. First, a groove 98 is provided at a corresponding position inside the housing 1, and the sliding plate 91 is slidably installed in the groove 98. In addition, two arc-shaped frames 92 are provided, and the arc-shaped frames 92 are fixedly connected to the sliding plate 91.

[0060] Additionally, the lifting connection mechanism 9 includes a support rod 93. The upper end of the support rod 93 is fixedly connected to the support plate 8, and the lower end is rotatably connected to a mounting plate 94. Two pulleys 95 are rotatably connected to one side of the mounting plate 94, and the two pulleys 95 are located on the upper and lower sides of the arc-shaped frame 92, respectively. The two pulleys 95 clamp the arc-shaped frame 92 in the middle.

[0061] When the sliding plate 91 moves the arc-shaped frame 92 to the left, the pulley 95 rolls against the surface of the arc-shaped frame 92. Simultaneously, because the arc-shaped frame 92 tilts upwards from left to right, the pulley 95 also moves upwards. At the same time, the mounting plate 94 and the support rod 93 move upwards together. When the support rod 93 moves upwards, it drives the tray 8 and the medicine box 7 to move upwards as well.

[0062] To ensure the stable upward movement of the support rod 93, a guide frame 96 is fitted around the outside of the support rod 93, and the support rod 93 passes through the guide frame 96. The guide frame 96 is fixedly connected to the housing 1. The guide frame 96 serves to guide the support rod 93.

[0063] Because the medicine box 7 needs to move upward to pick up the ointment only after the application part 3 is retracted into the housing 1, the aforementioned lifting connection mechanism 9 is connected to the drive mechanism 6 in Embodiment 1, so that the drive mechanism 6 can synchronously control the application part 3 and the medicine box 7. That is, while the application part 3 is retracted into the housing 1, the medicine box 7 moves upward.

[0064] Based on this, a lower connecting plate 97 is also fixedly connected to the sliding plate 91. To facilitate the connection between the lower connecting plate 97 and the aforementioned drive mechanism 6, a mounting opening 611 is provided on the horizontal section of the L-shaped upper connecting plate 61. Two spring rods 612 are fixedly installed within the mounting opening 611. Simultaneously, the upper end of the lower connecting plate 97 is inserted into the mounting opening 611, and a corresponding hole is provided on the lower connecting plate 97, through which the two spring rods 612 pass. Therefore, the lower connecting plate 97 can move along the direction of the spring rods 612, compressing the springs.

[0065] Additionally, a limit block 99 is provided inside the housing 1 and on one side of the lower connecting plate 97. Figure 3 (See annotation). As the upper connecting plate 61 moves to the left, it will cause the lower connecting plate 97 to move together. When the lower connecting plate 97 contacts the limit block 99, it stops moving. At this time, the upper connecting plate 61 can continue to move, while the lower connecting plate 97 compresses the spring on the outside of the spring rod 612.

[0066] Please refer to Figure 8 After a period of use, the amount of ointment will decrease, making it insufficient to supply ointment to the application area 3. In this case, the ointment container 7 needs to be removed to add ointment or replaced with a new one. Also, when the device will not be used for an extended period, the ointment container 7 should be removed and stored.

[0067] To facilitate the replacement of the medicine box 7, a baffle 10 is rotatably connected to one end of the housing 1 near the application section 3, and a magnetic snap 11 is installed between the baffle 10 and the housing 1. When the magnetic snap 11 between the baffle 10 and the housing 1 is engaged, the baffle 10 blocks the medicine box 7 from one end. At this time, the medicine box 7 cannot be removed. When the magnetic snap 11 is opened, the medicine box 7 can be pulled directly to the right from the tray 8, making it convenient to replace the medicine box 7 or to remove the medicine box 7 for separate storage.

[0068] In summary, the implementation process and principle of this application for a tool to facilitate wound application after drilling holes in corn stalks are as follows:

[0069] (a) The user can operate this device by holding the handle 12 with one hand. Two control buttons 13 control the forward and reverse rotation of the motor 65 in the drive mechanism 6. When the motor 65 drives the control shaft 64 to rotate forward and reverse, it drives the upper connecting plate 61 to move left and right reciprocally. As the upper connecting plate 61 moves, it drives the connecting shaft 2 to move together through the connecting piece 63 and the connecting ball 5. Due to the threaded connection between the connecting shaft 2 and the fixed sleeve 4, the connecting shaft 2 also rotates around its own axis when it moves.

[0070] by Figure 2 For example, when the upper connecting plate 61 drives the connecting shaft 2 to move to the left:

[0071] 1) The connecting shaft 2 and the coating part 3 move together to the left, and the coating part 3 is gradually retracted into the housing 1.

[0072] 2) The upper connecting plate 61 drives the lower connecting plate 97 to move to the left together. The lower connecting plate 97 drives the sliding plate 91 and the arc frame 92 to move together. During the movement of the arc frame 92, the support rod 93 will be driven upward through the pulley 95 and the mounting plate 94. The support rod 93 drives the tray 8 and the medicine box 7 to move upward.

[0073] 3) After the medicine box 7 moves upward, the application part 3 can contact the ointment inside the medicine box 7. At the same time, with the cooperation of the fixing sleeve 4, the connecting shaft 2 rotates during the movement, that is, the application part 3 can move and rotate at the same time. Therefore, the ointment inside the medicine box 7 can be adhered to the sponge material application part 3 to complete the automatic medicine application process.

[0074] (II) The user can operate the device by holding the handle 12 with one hand and aligning the applicator 3 with the hole on the corn stalk. The motor 65 and control shaft 64 are rotated in opposite directions via the control button 13, causing the connecting shaft 2 and applicator 3 to move in the opposite direction. As the applicator 3 rotates to the right, it enters the hole on the corn stalk. Because the applicator 3 is coated with ointment and is constantly rotating, it transfers the ointment into the corn stalk. The ointment is applied to the inner wall of the hole, sealing the wound on the corn stalk and protecting it.

[0075] (III) When it is necessary to remove the medicine box 7 or add new ointment, open the magnetic snap 11 between the baffle 10 and the housing 1, and the medicine box 7 can be pulled out directly to the right from the tray 8. Remove the medicine box 7 to facilitate the addition of new ointment, or remove the medicine box 7 for separate storage when the device is not used for a long time.

[0076] In summary, applying the ointment to the small holes in the corn stalks firstly prevents moisture loss through these holes and also prevents insects from further enlarging the wounds, reducing the possibility of rotting. This ensures smooth observation and research of the corn after inoculation. Secondly, this device can be operated with one hand and does not require direct contact with the ointment. Furthermore, changing the ointment is very convenient. Compared to manually applying ointment with cotton swabs, this device is more efficient. Since drilling often targets the lower half of the corn stalk, the part in contact with the ground, this improved application efficiency reduces the time the user spends bending over and squatting.

[0077] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
