Description

Technical Field

[0001] This application relates to the field of osmanthus grafting technology, and in particular to a grafting auxiliary device for osmanthus. Background Technology

[0002] Grafting is an artificial cultivation method that involves attaching a branch or bud of one plant to the stem or root of another plant, allowing the two parts to grow into a single, complete plant. To improve the adaptability and ornamental value of osmanthus, large-leaved privet, small-leaved privet, and fringe tree are commonly selected as rootstocks for grafting.

[0003] Currently, there are some grafting auxiliary devices for osmanthus on the market. For example, the utility model patent with authorization announcement number CN211671480U discloses a grafting auxiliary device for osmanthus, including a collar with a through hole inside. The through hole contains a rootstock. Two first threaded rods are symmetrically arranged through the side wall of the collar. Threaded holes corresponding to the first threaded rods are symmetrically arranged on the side wall of the collar. A clamping plate is rotatably set at the end of each of the two first threaded rods near the rootstock. The clamping plate is set tightly against the side wall of the rootstock. A rotating handle is fixedly connected to the end of the first threaded rod away from the rootstock. A cutting device is provided on the clamping plate.

[0004] The aforementioned patent enables the cutting of U-shaped grooves on the rootstock. However, the cutting device is mounted on a clamping plate, and once the clamping plate is fixed, the cutting position is fixed. If cutting is needed in other positions, the clamping plate must be disassembled and re-fixed, which is inconvenient. Furthermore, the cutting device requires manual cutting by the grafting personnel, resulting in low cutting efficiency. Based on this, this application proposes a grafting auxiliary device for osmanthus. Utility Model Content

[0005] This application provides a grafting auxiliary device for osmanthus. By rotating the blade holder, U-shaped grooves can be cut at multiple positions without disassembly and reinstallation, which is convenient and quick. Moreover, the U-shaped groove cutting process is driven by a motor, eliminating the need for manual operation by grafting personnel and improving cutting efficiency.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] A grafting aid for osmanthus, used to cut U-shaped grooves on rootstock, includes a mounting ring, two clamping plates, a blade holder, and a blade plate. The upper surface of the mounting ring is provided with an annular guide rail, and the ring wall of the mounting ring is provided with threaded holes. The clamping plates are provided with screws, and the end of the screws away from the clamping plates is provided with a handle. The two screws are rotatably connected to the two threaded holes, and the two clamping plates are located inside the mounting ring. One end of the blade holder is connected to the annular guide rail via a slider, and the other end of the blade holder is provided with a vertical support plate. The upper and lower ends of the vertical support plate are provided with ear plates, and the ear plates are rotatably connected to a lead screw. The upper end of the lead screw is driven by a motor. One end of the blade plate is provided with a mounting threaded hole that mates with the lead screw. The other end of the blade plate is provided with a U-shaped blade, and the U-shaped blade and the blade plate form an avoidance through hole.

[0008] In use, place the mounting ring on the rootstock, then turn the handle to firmly clamp the two clamps onto the rootstock, thus installing the entire device. Rotate the blade holder to the position where the grafting U-groove needs to be cut, then start the motor. The motor drives the lead screw to rotate, which in turn lowers the blade plate, allowing the U-shaped blade to cut into the rootstock. The cut portion enters the clearance hole, allowing the U-shaped blade to continue cutting downwards, thus creating the U-groove. Then, reverse the motor to raise the U-shaped blade and rotate the entire blade holder to the next position to cut the next U-groove.

[0009] Compared to existing technologies, the grafting auxiliary device used for this osmanthus can cut U-shaped grooves at multiple positions by rotating the blade holder, without the need for disassembly and reinstallation, which is convenient and quick. Moreover, the process of cutting the U-shaped grooves is driven by a motor, eliminating the need for manual operation by grafting personnel and improving cutting efficiency.

[0010] In one embodiment of this application, the tool holder is provided with a set screw, the lower end of which can abut against the upper surface of the mounting ring.

[0011] In one embodiment of this application, the vertical support plate is provided with a vertical guide groove, the blade is provided with a guide block, and the guide block cooperates with the vertical guide groove.

[0012] In one embodiment of this application, the blade includes an outer cylinder and an inner shaft. The mounting screw hole is disposed on the outer cylinder, and the inner shaft is slidably connected to the outer cylinder. The outer cylinder is provided with a locking screw hole, and a locking screw is fitted in the locking screw hole. The locking screw abuts against the inner shaft, and the U-shaped blade is mounted on the inner shaft.

[0013] In one embodiment of this application, the tool holder is provided with a mounting compartment, and a battery is installed in the mounting compartment. The battery is electrically connected to the motor.

[0014] In one embodiment of this application, the tool holder is provided with reinforcing ribs, and the reinforcing ribs are connected to the vertical support plate.

[0015] In one embodiment of this application, the lower end of the U-shaped blade forms a cutting edge.

[0016] In one embodiment of this application, the U-shaped blade is bolted to the blade plate.

[0017] In one embodiment of this application, the upper surface of the annular guide rail is provided with an angle scale. Attached Figure Description

[0032] An embodiment of this application provides a grafting auxiliary device for osmanthus, which can cut a U-shaped groove on the rootstock 010 to facilitate grafting of osmanthus by grafting personnel.

[0033] like Figure 1 As shown, the grafting auxiliary device for osmanthus includes a mounting ring 100, two clamps 200, a blade holder 300, and a blade 400. The mounting ring 100 is a structure for mounting and supporting other components, the clamps 200 are components for holding the rootstock 010, and the blade holder 300 and blade 400 are components for mounting the U-shaped blade 420.

[0034] like Figure 2 As shown, the upper surface of the mounting ring 100 is provided with an annular guide rail 110, which is coaxial with the mounting ring 100, providing a path for the circular motion of other components. The ring wall of the mounting ring 100 is provided with a threaded hole 120, which penetrates the mounting ring 100.

[0035] like Figure 3 As shown, the clamping plate 200 is provided with a screw 210, and the end of the screw 210 away from the clamping plate 200 is provided with a handle 220. The two screws 210 are rotatably connected to the two threaded holes 120 in a one-to-one correspondence, and the two clamping plates 200 are located inside the mounting ring 100. When the handle 220 is rotated, the clamping plate 200 can move closer to or away from the center of the mounting ring 100, thereby achieving clamping or loosening.

[0036] like Figure 1 and Figure 4 As shown, one end of the tool holder 300 is connected to the annular guide rail 110 via a slider 310, allowing it to perform circular motion. The other end of the tool holder 300 is provided with a vertical support plate 320. Both the upper and lower ends of the vertical support plate 320 are provided with ear plates 330. The ear plates 330 are rotatably connected to a lead screw 340. The upper end of the lead screw 340 is driven by a motor 350. When the motor 350 starts, it can drive the lead screw 340 to rotate.

[0037] like Figure 1 , Figure 4 and Figure 5As shown, one end of the blade plate 400 is provided with a mounting screw hole 410, which cooperates with the screw rod 340. When the screw rod 340 rotates, it can drive the blade plate 400 to rise and fall. The other end of the blade plate 400 is provided with a U-shaped blade 420. After the U-shaped blade 420 cuts the rootstock 010, it will cut out a small part of the rootstock 010 (roughly in the shape of a U-shaped block). The U-shaped blade 420 and the blade plate 400 form a clearance through hole 430. This small part of the rootstock 010 can be inserted into the clearance through hole 430, so that the U-shaped blade 420 can continue to cut downwards.

[0038] In use, the mounting ring 100 is placed on the rootstock 010, and then the handle 220 is turned to firmly clamp the two clamping plates 200 onto the rootstock 010, thus installing the entire device. The blade holder 300 is rotated to the position where the grafting U-shaped groove needs to be cut, and then the motor 350 is started. The motor 350 drives the lead screw 340 to rotate, which in turn drives the blade plate 400 to descend, so that the U-shaped blade 420 cuts into the rootstock 010. The cut part enters the clearance through hole 430, allowing the U-shaped blade 420 to continue cutting downwards, thereby achieving the cutting of the U-shaped groove. Then the motor 350 is reversed to raise the U-shaped blade 420, and the entire blade holder 300 is rotated to the next position to cut the next U-shaped groove.

[0039] Compared to existing technologies, the grafting auxiliary device used for this osmanthus can cut U-shaped grooves at multiple positions by rotating the blade holder 300, without the need for disassembly and reinstallation, which is convenient and quick. Moreover, the process of cutting the U-shaped grooves is driven by the motor 350, which does not require manual operation by the grafting personnel, thus improving cutting efficiency.

[0040] In some embodiments, such as Figure 4 As shown, the tool holder 300 is equipped with a set screw 360, the lower end of which can abut against the upper surface of the mounting ring 100. When the tool holder 300 is rotated to the position where the U-shaped groove needs to be cut, the set screw 360 can be screwed to make the set screw 360 tightly abut against the mounting ring 100, thereby limiting and fixing the tool holder 300 and ensuring the safety and reliability of the cutting process.

[0041] In some embodiments, such as Figure 4 As shown, the vertical support plate 320 is provided with a vertical guide groove 370, and the blade plate 400 is provided with a guide block 440. The guide block 440 cooperates with the vertical guide groove 370. When the motor 350 starts, the guide block 440 will rise and fall along the vertical guide groove 370, thereby preventing the blade plate 400 from tilting.

[0042] In some embodiments, such as Figure 6As shown, the blade 400 includes an outer cylinder 450 and an inner shaft 460. Both the outer cylinder 450 and the inner shaft 460 are generally rectangular in cross-section. A mounting screw hole 410 is provided on the outer cylinder 450. The inner shaft 460 is slidably connected to the outer cylinder 450. The outer cylinder 450 is provided with a locking screw hole, in which a locking screw 470 is fitted. The locking screw 470 abuts against the inner shaft 460. A U-shaped blade 420 is installed on the inner shaft 460, thereby adjusting the distance between the inner shaft 460 and the outer cylinder 450. By adjusting the position of the U-shaped blade 420, it is possible to cut anvils 010 of different diameters, thus improving the applicability of the entire device.

[0043] In some embodiments, such as Figure 4 As shown, the tool holder 300 is equipped with a mounting compartment 380, which contains a battery. The battery is electrically connected to the motor 350 and supplies power to the motor 350. In this structure, both the motor 350 and the battery are mounted on the tool holder 300 and rotate together with it, thus supplying power to the motor 350 without affecting the rotation of the tool holder 300.

[0044] In some embodiments, such as Figure 4 As shown, the tool holder 300 is provided with a reinforcing rib 390, which is connected to the vertical support plate 320, thereby improving the connection strength between the tool holder 300 and the vertical support plate 320 and improving the structural stability of the tool holder 300 and the vertical support plate 320.

[0045] In some embodiments, the lower end of the U-shaped blade 420 forms a cutting edge, facilitating cutting into the anvil 010.

[0046] In some embodiments, such as Figure 5 and Figure 6 As shown, the U-shaped blade 420 is connected to the blade plate 400 by bolts 480, realizing the detachable connection of the U-shaped blade 420. When the U-shaped blade 420 is damaged, it can be removed and replaced.

[0047] In some embodiments, the upper surface of the annular guide rail 110 is provided with an angle scale (not shown in the figure). When the blade holder 300 is rotated to a position, the angle of the blade holder 300 can be easily seen, making it convenient for the grafting personnel to move the blade holder 300 to a suitable position. For example, when four scions need to be grafted evenly onto a rootstock 010, the angle between two adjacent positions is 90 degrees. The blade holder 300 can be easily rotated into position using the angle scale.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
