Description

Technical Field

[0001] The utility model belongs to the technical field of pruning devices, and in particular relates to a rice leaf pruning device. Background Art

[0002] Rice bacterial blight is caused by Xanthomonas oryzae pv. Xanthomonas oryzae pv. oryzae, Xoo ) is a bacterial disease caused by Bacterial Blight. Bacterial blight mainly occurs on plant leaves, causing leaf necrosis. The pathogen enters from the leaf tip and leaf edge, initially forming yellow-green or dark green spots, which then expand into short water-soaked stripes that extend downward along the leaf edge, and finally the leaves wither and turn white.

[0003] Therefore, in order to further study the pathogenicity of Xanthomonas oryzae pathogenic variants to rice, the leaf cutting inoculation method is usually used to prevent and control rice, which mainly involves dipping the bacterial solution with scissors, and then cutting the tip of the rice leaf with the scissors dipped in the bacterial solution, so that the bacterial solution can be attached to the cut surface of the rice through the blade during shearing to complete the inoculation. However, the disadvantage of this method is that when dipping the bacterial solution, the bacterial solution can only be attached to the surface of the blade of the scissors, and the amount of bacterial solution that can be attached is small. Therefore, it cannot be guaranteed that the already small amount of bacterial solution can be attached to the cut surface of the rice; and because the amount of bacterial solution that can be attached at a time is small, after inoculating a few leaves, it is often impossible to continue inoculating other leaves. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the utility model provides a rice leaf cutting device.

[0005] The technical effects to be achieved by the utility model are achieved through the following technical aspects:

[0006] A rice leaf cutting device comprises: a first holding arm, a second holding arm, a first blade, a second blade, a telescopic cover and an adsorption layer for being filled with bacterial liquid required for multiple inoculations;

[0007] The first holding arm and the second holding arm are hinged, the first blade body is connected to the first holding arm, the second blade body is connected to the second holding arm, the first blade body and the second blade body have blades, one end of the telescopic cover is fixed on a surface of the second blade body facing the first blade body, and the other end is slidably arranged on a surface of the second blade body facing the first blade body, and a liquid guide port is provided on the telescopic cover, the adsorption layer is arranged in the telescopic cover, and the blade of the first blade body presses against the other end of the telescopic cover to extrude the bacterial liquid in the adsorption layer into the shear gap between the two blades along the direction of the liquid guide port.

[0008] In some embodiments, a guide adsorption layer is disposed on the second blade body, one end of the guide adsorption layer passes through the liquid guide port and is connected to the adsorption layer, and the other end of the guide adsorption layer is disposed close to the blade of the second blade body.

[0009] In some embodiments, a midline of the length of the telescopic cover coincides with a midline of the length of the second blade body.

[0010] In some embodiments, the other end surface of the telescopic cover is tilted to fit the edge of the blade when the first blade is shearing.

[0011] In some embodiments, the length of the liquid guide port is at least half of the length of the telescopic cover.

[0012] In some embodiments, a retaining strip for limiting the telescopic cover from being separated from the second blade body is disposed on the second blade body.

[0013] In some embodiments, an elastic member is disposed between the first holding arm and the second holding arm so that the blade of the first blade body is disposed away from the telescopic cover in a normal state.

[0014] In some embodiments, protective elements are disposed on the first blade and the second blade.

[0015] In some embodiments, both the first holding arm and the second holding arm are connected to a handle, and the handle is provided with an anti-slip layer.

[0016] In some embodiments, an identification piece is provided on the handle.

[0017] In summary, the utility model has at least the following benefits:

[0018] The rice leaf shearing device provided by the utility model, before use, the bacterial liquid required for multiple inoculations is injected into the telescopic cover through the liquid guide port, so that a large amount of bacterial liquid is adsorbed in the adsorption layer. When it is necessary to shear the tip of the rice leaf, the bottom end of the first holding arm and the bottom end of the second holding arm are held and closed by hand, so that the blades of the first blade body and the second blade body are close to each other. At this time, the blade of the first blade body presses the other end of the telescopic cover and exerts a pressing effect on the adsorption layer inside the telescopic cover, so that the bacterial liquid in the adsorption layer overflows from the liquid guide port, and the direction of the device is slightly adjusted so that the bacterial liquid fully flows to and adheres to the shearing gap between the two blades, then the first holding arm and the second holding arm are opened, and the device is brought close to the leaf tip, and the first holding arm and the second holding arm are closed again, so that the two blades with the bacterial liquid shear the tip of the rice leaf, so that the leaf section with the sheared tip is fully in contact with the bacterial liquid; and after the rice leaf is inoculated, the above operation can be repeated to inoculate other rice leaves until the bacterial liquid is exhausted. From this, it can be seen that by setting the telescopic cover and the adsorption layer, and setting the capacity of the adsorption layer to be larger, the amount of bacterial liquid that can be loaded by the device itself can be effectively increased, thereby ensuring that the bacterial liquid is fully dipped onto the cut surface of the rice leaves during shearing, and facilitating continuous inoculation of more rice leaves at one time.

The described implementation is a part of the implementation of the utility model, not all of the implementations.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0026] In the following embodiments and drawings, reference is made to Figure 1 In the coordinate system, the direction indicated by the arrow of the X-axis is right, the direction indicated by the arrow of the Y-axis is forward, and the direction indicated by the arrow of the Z-axis is up.

[0027] Embodiment 1:

[0028] like Figures 1 to 3 As shown, in this embodiment, a rice leaf cutting device 10 is provided, comprising: a first holding arm 100, a second holding arm 200, a first blade 300, a second blade 400, a telescopic cover 600 and an adsorption layer 610 for filling with bacterial solution required for multiple inoculations; the first holding arm 100 and the second holding arm 200 are hinged, the first blade 300 is connected to the first holding arm 100, the second blade 400 is connected to the second holding arm 200, and the first blade 300 and the second blade 400 have blades 5 00, one end of the telescopic cover 600 is fixed on the surface of the second blade body 400 facing the first blade body 300, and the other end is slidably arranged on the surface of the second blade body 400 facing the first blade body 300, and a liquid guide port 620 is opened on the telescopic cover 600, and the adsorption layer 610 is arranged in the telescopic cover 600, and the blade 500 of the first blade body 300 presses against the other end of the telescopic cover 600 to squeeze the bacterial liquid in the adsorption layer 610 along the direction of the liquid guide port 620 into the shear gap between the two blades 500.

[0029] Specifically, the first blade 300 is integrated with the first holding arm 100, and the second blade 400 is integrated with the second holding arm 200. The bottom end of the first holding arm 100 and the bottom end of the second holding arm 200 are used for holding, and the top end of the first holding arm 100 and the top end of the second holding arm 200 can be optionally but not limited to pin-connected, so that the blade 500 of the first blade 300 and the blade 500 of the second blade 400 can be cross-cut, and the first blade 300 is arranged on the front side of the second blade 400, the tips of the two blades 500 are arranged in reverse, and the tip of the blade 500 of the second blade 400 is arranged on the rear side, wherein the manner in which the blade 500 of the first blade 300 and the blade 500 of the second blade 400 are close to each other for shearing is known to those skilled in the art and is achievable, and is not described in detail in this embodiment; the material of the telescopic cover 600 can be optionally but not limited to plastic, which can play a fixing and protective role on the internal adsorption layer 610 , and to a certain extent, it can prevent rainwater or dirt from the outside from infecting the internal adsorption layer 610. The right end of the telescopic cover 600 is tightly attached to the front surface of the second blade 400. The left end of the telescopic cover 600 is movably abutted against the blade 500 of the first blade 300. The end of the telescopic cover 600 close to the blade 500 of the first blade 300 is provided with a liquid guide port 620, that is, the left end of the telescopic cover 600 is provided with a liquid guide port 620, and the liquid guide port 620 is used to introduce and export bacterial liquid. The length of the liquid guide port 620 is smaller than that of the telescopic cover 600 to prevent the telescopic cover 600 from easily separating from the second blade 400 under the abutment of the blade 500, and the length of the liquid guide port 620 is at least half of the length of the telescopic cover 600 to facilitate rapid drainage of the bacterial liquid. The specific layout of the liquid guide port 620 is based on actual production needs and is not limited here. It only needs to ensure that the bacterial liquid can be introduced and drained to the designated position; the material of the adsorption layer 610 can be selected from but not limited to sterile cotton.

[0030] It is worth noting that, before use, the bacterial solution required for multiple inoculations is injected into the telescopic cover 600 through the liquid guide port 620, so that a large amount of bacterial solution is adsorbed in the adsorption layer 610. When it is necessary to cut the tip of the rice leaf, the bottom end of the first holding arm 100 and the bottom end of the second holding arm 200 are held and closed by hand, so that the blades 500 of the first blade body 300 and the second blade body 400 are close to each other. At this time, the blade 500 of the first blade body 300 presses against the other end of the telescopic cover 600 and presses against the adsorption layer 610 inside it, so that the bacteria in the adsorption layer 610 are adsorbed. The liquid overflows from the liquid guide port 620, and the direction of the device is slightly adjusted so that the bacterial liquid fully flows to and adheres to the shear gap between the two blades 500, then the first holding arm 100 and the second holding arm 200 are opened, and the device is brought close to the tip of the leaf, and the first holding arm 100 and the second holding arm 200 are closed again, so that the two blades 500 with the bacterial liquid cut off the tip of the rice leaf, so that the cut surface of the leaf with the cut tip can be fully in contact with the bacterial liquid; and after inoculating this rice leaf, the above operation can be repeated to inoculate other rice leaves until the bacterial liquid is exhausted. From this, it can be seen that by setting the telescopic cover 600 and the adsorption layer 610, and setting the capacity of the adsorption layer 610 larger, the amount of bacterial liquid that can be loaded by the device itself can be effectively increased, and then it can be ensured that the bacterial liquid is fully dipped onto the cut surface of the rice leaf during shearing, and it is convenient to continuously inoculate more rice leaves at one time. When the blade 500 can no longer squeeze out the bacterial liquid, the telescopic cover 600 can be manually pressed to squeeze out the remaining bacterial liquid.

[0031] Example 2

[0032] This embodiment is a further implementation of embodiment 1. Figure 2 and Figure 3 As shown, in this embodiment, a guiding adsorption layer 410 is provided on the second blade body 400 , one end of the guiding adsorption layer 410 passes through the liquid guide port 620 to connect with the adsorption layer 610 , and the other end of the guiding adsorption layer 410 is provided close to the blade 500 of the second blade body 400 .

[0033] Specifically, the guiding adsorption layer 410 may be selected but not limited to a thinner cotton layer, and the upper and lower ends of the guiding adsorption layer 410 are bonded to the second blade 400, and the bacterial liquid is drained through the unbonded part in the middle of the guiding adsorption layer 410. By providing the guiding adsorption layer 410, the bacterial liquid overflowing from the liquid guide port 620 can be diverted to the blade 500 of the second blade 400, so that it is convenient to quickly divert the bacterial liquid to the blade 500, and the waste caused by the outflow of the bacterial liquid can be avoided. It can be understood that the specific layout of the guiding adsorption layer 410 is not limited here, and it is only necessary to ensure that it can be diverted to the shear gap between the two blades 500. For example, the guiding adsorption layer 410 can be L-shaped, with one end connected to the adsorption layer 610 and the other end bonded to the edge of the blade 500 of the second blade 400.

[0034] It is understandable that when cutting objects with scissors, the general usage habit is to cut through the middle and lower parts of the blade 500. Therefore, in order to facilitate the cutting habit and increase the practicality of the device, Figure 1 As shown, in some embodiments, the length midline of the telescopic cover 600 is arranged to coincide with the length midline of the second blade body 400 .

[0035] Specifically, the upper and lower ends of the blade body and the upper and lower ends of the blade 500 are arranged flush with each other, the right end peripheral side of the telescopic cover 600 is bonded and fixed to the front side surface and the right end surface of the second blade body 400, and the telescopic cover 600 is arranged in the middle of the second blade body 400. In this way, when the researcher operates the middle part of the first blade body 300 and the middle part of the second blade body 400 to approach each other, the blade 500 of the first blade body 300 squeezes the telescopic cover 600, so that part of the bacterial liquid remains on the middle and lower blade 500 of the first blade body 300, and when the first blade body 300 leaves the telescopic cover 600 after squeezing, the bacterial liquid on the first blade body 300 can reach the middle and lower blade 500 of the second blade body 400 with the movement of its blade 500. At this time, the first blade body 300 and the second blade body 400 are closed again for shearing, so that shearing can be performed through the middle and lower blade 500 stained with the bacterial liquid. In this way, the bacterial liquid can be evenly attached to the two blades 500, and it is more in line with the shearing habits of the operator, so that the poor bacterial liquid dipping effect caused by the telescopic cover 600 being too far away from the gripping part can be effectively avoided, and the inconvenience of shearing caused by the telescopic cover 600 being too close to the gripping part can also be avoided.

[0036] In order to squeeze out the bacterial liquid in the telescopic cover 600 more quickly, in some embodiments, the other end surface of the telescopic cover 600 is tilted to fit the edge of the blade 500 when the first blade 300 is shearing.

[0037] Specifically, the left end surface of the telescopic cover 600 is tilted and matched with the inclination of the edge of the blade 500 when the first blade body 300 is shearing. In this way, during the shearing process, the left end surface of the telescopic cover 600 and the edge of the blade 500 of the first blade body 300 are completely in contact, so that the blade 500 of the first blade body 300 can completely press the left end surface of the telescopic cover 600 when they just come into contact, so that the effect of squeezing the bacterial liquid is better.

[0038] In order to prevent the telescopic cover 600 from being separated from the second blade 400, Figure 1 and Figure 3 As shown, in some embodiments, a retaining strip 420 is disposed on the second blade body 400 for limiting the telescopic cover 600 from being separated from the second blade body 400 .

[0039] Specifically, the number of the retaining strips 420 may be selected but not limited to two, and the retaining strips 420 may be selected but not limited to adhesive tapes, and the retaining strips 420 adhere and fix the right end of the telescopic cover 600 to the front surface of the second blade 400 to limit the displacement of the upper and lower ends of the telescopic cover 600, thereby preventing the telescopic cover 600 from easily detaching from the second blade 400 to a certain extent. It can be understood that the specific arrangement of the retaining strips 420 is not limited here, and it is only necessary to ensure that the telescopic cover 600 is prevented from easily detaching from the second blade 400. For example, two retaining strips 420 are fixed to the right end of the telescopic cover 600 in a V shape, the left ends of the two retaining strips 420 fix the upper and lower ends of the telescopic cover 600, and the right ends of the two retaining strips 420 fix the right end of the telescopic cover 600, so that the upper and lower ends and the right end of the telescopic cover 600 are supported by the adhesive tapes adhered to the second blade 400, so that the moving path of the left end of the telescopic cover 600 is more fixed.

[0040] Example 3

[0041] This embodiment is a further implementation of embodiment 1 or 2. In this embodiment, an elastic member is disposed between the first holding arm 100 and the second holding arm 200 so that the blade 500 of the first blade body 300 is disposed away from the telescopic cover 600 in a normal state.

[0042] Specifically, the elastic member may be selected from but not limited to a spring, and the elastic action of the spring allows the first blade 300 and the second blade 400 to remain in an open state under normal conditions, thereby effectively preventing waste caused by squeezing the bacterial solution when the rice leaves are not inoculated. The manner in which the spring is installed between the first holding arm 100 and the second holding arm 200 is known to those skilled in the art and is achievable, and is not described in detail in this embodiment.

[0043] In order to increase the practicality of the device, in some embodiments, protective members are provided on the first blade body 300 and the second blade body 400 .

[0044] Specifically, the protective member may be selected from but not limited to a silicone protective shell. By providing a silicone protective shell on the top of the first blade 300 and the top of the second blade 400, the two blades 500 can be prevented from accidentally injuring the operator when opened, making the rice leaf cutting device 10 more practical.

[0045] To facilitate the use of the device, Figure 1 and Figure 2 As shown, in some embodiments, the first holding arm 100 and the second holding arm 200 are both connected to a handle 700 , and the handle 700 is provided with an anti-slip layer.

[0046] Specifically, the handle 700 may be, but is not limited to, a ring handle, and the material of the handle 700 may be, but is not limited to, plastic. By plugging the first gripping arm 100 and the second gripping arm 200 into the corresponding handle 700, the first blade 300 and the second blade 400 may be driven to cut by the handle 700, making it more convenient to use. The anti-slip layer may be, but is not limited to, a plurality of rubber bumps. The anti-slip effect of the anti-slip layer may facilitate the operator to grip the device and prevent the device from slipping out of the hand easily.

[0047] In order to increase the practicality of the device, in some embodiments, an identification piece is provided on the handle 700 .

[0048] Specifically, an identification piece is hung on the handle 700 through a rope loop, and the identification piece may be selected from but not limited to a hard card, so that the function of the device can be marked on the hard card, so as to remind others and prevent misuse. Alternatively, the date of the bacterial solution can be marked on the hard card to facilitate inoculation.

[0049] Example 4

[0050] This embodiment is similar to Embodiment 1, 2 or 3, except that the telescopic cover 600 is detachably connected to the second blade body 400.

[0051] Specifically, the right end of the second blade body 400 is movablely clamped with a positioning clamp, the rear surface of the positioning clamp is in contact with one side of the second blade body 400, the front surface of the positioning clamp is provided with two elastic pressure strips, and the two elastic pressure strips press the upper and lower ends of the telescopic cover 600 on the front surface of the second blade body 400, and the upper and lower ends of the telescopic cover 600 are both protruding from the two elastic pressure strips.

[0052] Specifically, the elastic strip is set as a metal sheet, and the two elastic strips are set close to the rear surface of the clamp under normal conditions, so that the right end of the telescopic cover 600 is fixed. When the blade 500 of the first blade 300 squeezes the telescopic cover 600, the blade 500 passes over the elastic strip to squeeze the telescopic cover 600, driving the left end of the telescopic cover 600 to shrink toward the middle of the two elastic strips to squeeze the bacterial liquid. In this way, the telescopic cover 600 and the internal adsorption layer 610 can be replaced by removing the clamp, which effectively increases the practicality of the device. And the detachable connection method of the telescopic cover 600 and the second blade 400 shall be based on actual production needs, and is not limited here. It is only necessary to ensure the detachable connection between the two.
