Description

Technical Field

[0001] This utility model relates to the field of medicine application technology for forest tree incisions, and more specifically, it relates to a medicine application mechanism for forest tree incisions. Background Technology

[0002] In the field of forestry tree maintenance, existing pesticide application equipment suffers from serious technical defects and limitations in use. These problems not only affect work efficiency but may also lead to poor treatment results. Specifically, these technical challenges are mainly reflected in the following key aspects:

[0003] Firstly, in the daily maintenance of forest trees, the traditional method of applying medicine mainly relies on manual operation, which involves dripping medicine onto the surface of tree wounds and then spreading it evenly with a brush. As the core working component, the brush inevitably suffers from wear and deformation during long-term use and needs to be replaced regularly to ensure the effectiveness of the medicine application. However, the existing equipment has an unreasonable brush installation structure design, and the disassembly and assembly process is cumbersome and time-consuming, which not only reduces work efficiency but also increases the labor intensity of maintenance personnel. This inconvenient maintenance method seriously affects the practicality of the equipment and the continuity of work.

[0004] Secondly, although some improved equipment has emerged on the market, using a delivery pipeline system to deliver the medicine to the brush for application, these devices generally suffer from overly simplistic medicine delivery systems. Most employ a fixed delivery rate, which cannot adapt to the physiological characteristics of different tree species and the differences in wound size. It also cannot flexibly adjust the delivery speed according to seasonal changes, temperature, humidity, and other environmental factors. In practical applications, there are significant differences in bark thickness and absorption capacity among different tree species, and environmental factors can also affect the penetration effect of the medicine. A fixed delivery speed often leads to excessive use of medicine, resulting in waste, or insufficient use, affecting the treatment effect, which seriously restricts the accuracy and effectiveness of the application of medicine.

[0005] More importantly, although some improved equipment has emerged on the market, adding drug flow rate adjustment functions in an attempt to improve the adaptability of the equipment, these improved designs still have serious structural defects. The main problem is that these simple adjustment structures are prone to stability issues during actual use. Specifically, the impact force generated by the continuous flow of the liquid in the pipeline may cause the adjustment structure to loosen. This lack of structural stability directly affects the accuracy of drug delivery, causing the carefully adjusted flow rate parameters to deviate during use. This not only affects the application effect but may also lead to excessive waste or insufficient supply of the drug, seriously affecting the treatment effect of tree wounds. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a drug application mechanism for forestry tree incisions, which has the following beneficial effects:

[0019] 1. The assembly device achieves rapid assembly and disassembly of the brush through the scientific combination of a rotating shaft, screw, screw sleeve, clearance groove, brush, and fixing plate. The rotating plate drives the screw sleeve to rotate, which enables rapid tightening and loosening of the fixing plate. The cooperation between the clearance groove and the screw ensures the smoothness of the assembly and disassembly process, enabling rapid assembly and disassembly of the brush and thus rapid brush replacement. The design of the insert and slot provides a reliable positioning effect, and the setting of the flow groove and flow hole enables the uniform distribution of the medicine. This fundamentally solves the technical problem of cumbersome brush assembly and disassembly in traditional medicine application mechanisms.

[0020] 2. The control device adopts an innovative combination of components such as connecting pipe, control sleeve, connecting frame, conical block, mating rod, mating sleeve, fixed pipe, adapter frame, adapter rod, and adapter plate. The movement of the mating rod is controlled by the linkage mechanism of the control sleeve and the mating sleeve. The limiting effect of the movable frame and the movable block realizes the precise movement of the conical block. At the same time, the adapter spring pushes the adapter plate to slide with the mating rod to ensure a tight fit with the conical block, making the position of the adapter plate controllable. This enables precise adjustment of the liquid flow rate, which can adapt to different tree species and different environments, and completely overcomes the technical defects of fixed liquid delivery speed in traditional medicine application mechanisms.

[0021] 3. The self-locking mechanism achieves reliable locking of the adjustment structure through the ingenious cooperation of the release groove, release plate, locking plate, connecting plate, sliding sleeve, movable spring, locking rod, and locking groove. The rotational cooperation between the release plate and the release groove enables flexible restriction of the locking plate position, while the elastic cooperation between the movable spring and the locking rod ensures a stable locking effect. The rounded corner design of the locking groove ensures the smooth movement of the locking rod, fundamentally solving the technical problem of easy deviation after flow rate adjustment in traditional medicine application mechanisms.

[0031] Please see Figures 1-5 A medication application mechanism for forestry tree incisions includes a fixed frame 1. An assembly device is located on one side of the fixed frame 1, and a control device is connected to the other side of the fixed frame 1. The control device includes a connecting pipe 2, a control sleeve 3, a connecting frame 4, a conical block 5, a mating rod 6, a mating sleeve 7, a fixed pipe 8, an adapter frame 9, an adapter rod 10, and an adapter plate 11. The two ends of the control sleeve 3 are rotatably connected to the connecting pipe 2 and the fixed pipe 8, respectively. The inner wall of the control sleeve 3 is fixedly connected to the outer wall of the mating sleeve 7 via the connecting frame 4. The conical block 5 is fixedly connected to one end of the mating rod 6. The mating sleeve 7 is threadedly fitted onto the outside of the mating rod 6. The fixed pipe 8 is fixedly connected to one side of the fixed frame 1. The adapter frame 9 is fixedly installed in the connecting pipe 2. The adapter rod... 10 is slidably mounted on the adapter frame 9. The adapter plate 11 is movably connected to the inner wall of the connecting tube 2. A self-locking mechanism is provided on the outer side of the connecting tube 2. The self-locking mechanism includes a release groove 12, a release plate 13, a locking plate 14, a connecting plate 15, a sliding sleeve 16, a movable spring 17, a locking rod 18, and a locking slot 19. The release groove 12 is opened on the release plate 13. The release plate 13 is rotatably sleeved on the outer side of the connecting tube 2. The locking plate 14 is fixedly connected to one side of the connecting plate 15. The connecting plate 15 is connected to one side of the sliding sleeve 16. The sliding sleeve 16 is slidably sleeved on the outer side of the connecting sleeve. One end of the locking rod 18 is connected to the outer wall of the control sleeve 3 through the movable spring 17. The other end of the locking rod 18 is inserted into the locking slot 19. Multiple locking slots 19 are opened on the outer side of the connecting tube 2.

[0032] A movable frame 20 is connected to the outside of the connecting rod 6, and a movable block 21 is fixedly provided on the outside of the movable frame 20. A movable groove 22 is opened inside the connecting pipe 2, and the movable block 21 is slidably disposed in the movable groove 22.

[0033] The adapter plate 11 is provided with an adapter spring 23 on one side, and the adapter plate 11 is connected to the inner wall of the connecting tube 2 through the adapter spring 23.

[0034] In this embodiment, when it is necessary to adjust the delivery speed of the liquid medicine, the release plate 13 is rotated, causing the release plate 13 to move the release groove 12 to the position corresponding to the clamping plate 14. Then, the sliding sleeve 16 is pushed, causing the sliding sleeve 16 to gradually pass through the release groove 12 along with the connecting plate 15 and the clamping plate 14. When one of the clamping plates 14 passes through the release groove 12 and reaches the other side of the release plate 13, the release plate 13 is rotated again, causing the release plate 13 to move the release groove 12 to a position that does not correspond to the clamping plate 14. This allows the connecting plate 15 and the clamping plate 14 to cooperate in limiting the sliding sleeve 16 to one side of the release plate 13, thus preventing the sliding sleeve 16 from resetting. At this time, the sliding sleeve 16 no longer limits the clamping rod 18. Then, the control sleeve 3 is rotated, and the control sleeve 3 will drive... Multiple locking rods 18 on the side wall move, and then the side wall of the locking groove 19 presses against the end of the locking rod 18. Due to the rounded corner design at the end of the locking rod 18 and the edge of the locking groove 19, one end of the locking rod 18 slides out of the locking groove 19, and the other end of the locking rod 18 drives the movable spring 17 to stretch. At the same time, the control sleeve 3 drives the mating sleeve 7 to rotate through the connecting frame 4. Since the mating sleeve 7 and the mating rod 6 are connected by threads, and the movable block 21 and the movable groove 22 cooperate to limit the movable frame 20 and the mating rod 6, the movable frame 20 and the mating rod 6 cannot rotate. Then the mating rod 6 drives the movable frame 20 and the movable block 21 to slide along the movable groove 22, and the mating rod 6 drives the conical block 5 to slide, causing the conical block 5 to move downward. As the conical block 5 moves downward, the adapter spring 23 pushes the adapter plate 11 inward, and the other side of the adapter plate 11 pushes the adapter rod 10 to slide along the adapter frame 9, so that one end of the adapter rod 10 always abuts against the outer wall of the conical block 5. The movement of the adapter plate 11 changes the cross-sectional area of ​​the corresponding position in the connecting pipe 2, thereby changing the flow area of ​​the liquid and thus changing the flow speed of the liquid. When the appropriate flow rate is adjusted, the rotation of the control sleeve 3 is stopped, and the movable spring 17 drives the locking rod 18 to reset. Then, one end of the locking rod 18 will be inserted into the corresponding locking groove 19. Then, the release plate 13 is rotated again, so that the release plate 13 drives the release groove 12 to move again to the position corresponding to the locking plate 14, and then pushes the sliding sleeve 16 in the opposite direction. This causes the sliding sleeve 16 to slide and reset. At the same time, the sliding sleeve 16 will drive the connecting plate 15 and the clamping plate 14 to slide and reset. When the sliding sleeve 16 is fully reset, the other two clamping plates 14 will move to the two sides of the release plate 13 respectively. Then, the release plate 13 will be rotated again, causing the release plate 13 to drive the release groove 12 to a position that does not correspond to the clamping plate 14. At this time, the connecting plate 15 and the two clamping plates 14 cooperate to limit the sliding sleeve 16 to one side of the release plate 13, so that the sliding sleeve 16 cannot slide. Then, the inner wall of the sliding sleeve 16 will limit the outer end of the clamping rod 18 again, so that the clamping rod 18 will not move. Then, the clamping rod 18 and the clamping groove 19 cooperate to limit the control sleeve 3, preventing the control sleeve 3 from moving, thereby ensuring the structural stability after the flow rate adjustment.

[0035] Please see Figures 1-3 As one embodiment of the assembly device: the assembly device includes a rotating shaft 24, a screw 25, a screw sleeve 26, a relief groove 27, a brush 28, and a fixing plate 29. The brush 28 is fixedly connected to one side of the fixing plate 29. The fixing plate 29 is detachably installed inside the fixing frame 1. The rotating shaft 24 is rotatably installed inside the fixing frame 1. The screw 25 is connected to the outside of the rotating shaft 24. The screw sleeve 26 is movably sleeved on the outside of the screw 25 by thread. The relief groove 27 is formed on the fixing plate 29.

[0036] A rotating plate 30 is fixed on the outside of the threaded sleeve 26.

[0037] A plug 31 is fixedly provided on one side of the fixing plate 29, and a slot 32 is provided on one side of the fixing bracket 1, into which the plug 31 is inserted.

[0038] One end of the connecting pipe 2 is connected to a conveying pipe 33, and a flow groove 34 is opened on one side of the fixing plate 29. A flow hole 35 is opened in the flow groove 34 and passes through the fixing plate 29.

[0039] A fixing rod 36 is fixedly connected to one side of the fixing frame 1.

[0040] More specifically, when the device is needed, it is connected to a traditional medicine box via the delivery pipe 33. The user can carry the external medicine box on their back and then deliver the prepared medicine solution to the delivery pipe 33. The solution is then delivered through the delivery pipe 33 into the flow channel 34, and then flows through the flow channel 34 into various flow holes 35, thus penetrating the fixing plate 29 and seeping into the brush 28. The user can then directly apply the solution evenly through the cut of the tree using the brush 28. When the brush 28 needs to be replaced, first rotate the screw sleeve 26 using the rotating plate 30, causing the screw sleeve 26 to rotate along the thread on the outside of the screw 25. The fixing plate 29 is no longer pressed against one side of the fixing frame 1. Then, the screw 25 is turned so that it rotates out of the relief groove 27 along the pivot 24. The fixing plate 29 is then bent to one side so that the insert 31 slides out of the slot 32, allowing the brush 28 to be removed and replaced with a new brush 28. The insert 31 on one side of the fixing plate 29 is inserted into the slot 32 on one side of the fixing frame 1 for positioning. Then, the screw 25 is rotated back into the relief groove 27 along the pivot 24. Then, the screw sleeve 26 is reversed by the rotating plate 30 so that the screw sleeve 26 presses the fixing plate 29 back against one side of the fixing frame 1, thus achieving a quick replacement of the brush 28.

[0041] In summary, during the use or operation of the overall equipment: when it is necessary to adjust the delivery speed of the liquid medicine, rotate the release plate 13, causing the release plate 13 to move the release groove 12 to the position corresponding to the clamping plate 14. Then, push the sliding sleeve 16, causing the sliding sleeve 16 to gradually pass through the release groove 12 along with the connecting plate 15 and the clamping plate 14. When one of the clamping plates 14 passes through the release groove 12 and reaches the other side of the release plate 13, continue to rotate the release plate 13, causing the release plate 13 to move the release groove 12 to a position that does not correspond to the clamping plate 14. This allows the connecting plate 15 and the clamping plate 14 at this point to cooperate in limiting the sliding sleeve 16 to one side of the release plate 13, thus preventing the sliding sleeve 16 from resetting. At this point, the sliding sleeve 16 no longer limits the clamping rod 18. Then, rotate the control sleeve 3. The control sleeve 3 moves multiple locking rods 18 on its side wall. The side wall of the slot 19 then presses against the ends of the locking rods 18. Due to the rounded corners at the ends of the locking rods 18 and the edges of the slot 19, one end of the locking rod 18 slides out of the slot 19, and the other end of the locking rod 18 stretches the movable spring 17. Simultaneously, the control sleeve 3 rotates the mating sleeve 7 via the connecting frame 4. Since the mating sleeve 7 and the mating rod 6 are connected by threads, and the movable block 21 and the movable slot 22 limit the movement of the movable frame 20 and the mating rod 6, the movable frame 20 and the mating rod 6 cannot rotate. The mating rod 6 then drives the movable frame 20 and the movable block 21 to slide along the movable slot 22, and the mating rod 6 also drives the conical block 5 to slide, causing the conical block 5 to... As the cone-shaped block 5 moves downward, the adapter spring 23 pushes the adapter plate 11 inward, and the other side of the adapter plate 11 pushes the adapter rod 10 to slide along the adapter frame 9, so that one end of the adapter rod 10 always abuts against the outer wall of the cone-shaped block 5. The movement of the adapter plate 11 changes the cross-sectional area of ​​the corresponding position in the connecting pipe 2, thereby changing the flow area of ​​the liquid and thus changing the flow speed of the liquid. When the appropriate flow rate is adjusted, the control sleeve 3 is stopped from rotating, and the movable spring 17 drives the locking rod 18 to reset. Then, one end of the locking rod 18 is inserted into the corresponding slot 19. Then, the release plate 13 is rotated again, so that the release plate 13 drives the release groove 12 to move again to the position corresponding to the locking plate 14, and then pushes the sliding rod in the opposite direction. The sleeve 16 is slidably reset, causing the connecting plate 15 and the locking plate 14 to slide and reset. When the sleeve 16 is fully reset, the other two locking plates 14 move to the sides of the release plate 13 respectively. Then the release plate 13 is rotated again, causing the release groove 12 to move to a position that does not correspond to the locking plate 14. At this time, the connecting plate 15 and the two locking plates 14 cooperate to limit the sleeve 16 to one side of the release plate 13, so that the sleeve 16 cannot slide. Then the inner wall of the sleeve 16 limits the outer end of the locking rod 18 again, so that the locking rod 18 will not move. Then the locking rod 18 and the locking groove 19 cooperate to limit the control sleeve 3, preventing the control sleeve 3 from moving, thereby ensuring the structural stability after the flow rate adjustment.

[0042] When the device is needed, it is connected to a traditional medicine box via the delivery pipe 33. The user can carry the external medicine box on their back and then deliver the prepared medicine solution to the delivery pipe 33. The solution is then transported through the delivery pipe 33 to the flow channel 34, and then flows through the flow channel 34 to various flow holes 35, thus penetrating the fixing plate 29 and seeping into the brush 28. The user can then directly apply the solution evenly through the cut of the tree using the brush 28. When the brush 28 needs to be replaced, first rotate the screw sleeve 26 using the rotating plate 30, causing the screw sleeve 26 to rotate along the thread on the outside of the screw 25, so that the screw sleeve 26 no longer... The fixing plate 29 is pressed against one side of the fixing frame 1. Then, the screw 25 is turned so that it rotates out of the relief groove 27 along the pivot 24. The fixing plate 29 is then bent to one side so that the insert 31 slides out of the slot 32, allowing the brush 28 to be removed and replaced with a new brush 28. The insert 31 on one side of the fixing plate 29 is inserted into the slot 32 on one side of the fixing frame 1 for positioning. The screw 25 is then rotated back into the relief groove 27 along the pivot 24. The screw sleeve 26 is then reversed by the rotating plate 30 so that it presses the fixing plate 29 back against the fixing frame 1, thus enabling the quick replacement of the brush 28.
