Description

Technical Field

[0001] This invention belongs to the field of forest pest control, and in particular relates to a trunk drilling and injection device for controlling forest pests and diseases. Background Technology

[0002] With the arrival of spring and rising temperatures, various diseases also emerge. Common tree trunk diseases include rot, gummosis, and canker. Therefore, it is essential to prevent and control the spread of pathogens as early as possible and to carry out effective prevention and control measures for garden plant diseases.

[0003] Currently, when protecting against forest pests and diseases, sprayers are generally used to spray pesticides on trees. However, under certain conditions, it is necessary to drill holes in the tree trunks and then inject the pesticide solution into the holes in order to achieve the purpose of preventing and controlling pests and diseases and protecting trees.

[0004] The existing methods of drug injection mostly involve manually drilling holes in the tree trunk with a handheld electric drill and then injecting the drug solution into the holes. Since the holes are usually located 30-50 centimeters above the ground, workers often need to squat to work. In addition, the entire injection process usually takes 3-5 minutes, which often causes the workers' legs to become numb. This not only seriously depletes the workers' physical strength but also affects subsequent injection operations, greatly reducing the efficiency of drug injection. Summary of the Invention

[0005] The purpose of this invention is to provide a trunk drilling and injection device for the prevention and control of forest pests and diseases, which aims to solve the technical problem of low injection efficiency caused by manual injection in the prior art.

[0006] This invention is implemented as follows: a trunk drilling and injection device for controlling forest pests and diseases includes a vehicle body, which consists of a frame, handlebars, and casters. A circumferential mechanism is installed on the top of the vehicle body to fix the vehicle body relative to the tree trunk. An installation frame is fixedly installed on the vehicle body, and an adjustment mechanism is installed on the installation frame. An injection mechanism is installed at the output end of the adjustment mechanism. The adjustment mechanism is used to adjust the horizontal position, vertical position, and angle of the injection mechanism. The injection mechanism is used to drill holes and inject pesticide into the tree trunk.

[0007] Further technical solution: The embracing mechanism includes two ring arms. Two first linear modules are fixedly installed on the vehicle body. The two ring arms are respectively fixedly installed on the output ends of the two first linear modules. The ends of the ring arms away from the vehicle body are hinged to a retaining arm. A torsion spring is provided between the retaining arm and the ring arm, so that the retaining arm tends to open. The end of the ring arm is provided with a limiting baffle adapted to the retaining arm. The embracing mechanism also includes two closing mechanisms. The two closing mechanisms are respectively installed on the two ring arms. The output end of the closing mechanism is connected to the retaining arm. The closing mechanism is used to drive the retaining arm to rotate so that the retaining arm moves closer to the ring arm so that the tree trunk can pass through.

[0008] Further technical solution: The closing mechanism includes a second mounting slot and a first mounting slot formed on the ring arm. A take-up reel is rotatably mounted inside the second mounting slot, and a pull rope is wound on the take-up reel. A reversing pulley is rotatably mounted inside the first mounting slot. The pull rope passes through the ring arm and is fixedly connected to the arm after passing around the reversing pulley. A first servo motor is also fixedly mounted on the ring arm, and the output shaft of the first servo motor is fixedly connected to one end of the take-up reel.

[0009] Further technical solution: The adjustment mechanism includes a second linear module, which is fixedly mounted on a mounting frame. An electric telescopic rod is fixedly mounted on the output end of the second linear module. A second mounting plate is fixedly mounted on the movable end of the electric telescopic rod. A rail box is rotatably mounted on the second mounting plate. A slider is slidably mounted inside the rail box. A first lead screw is rotatably mounted inside the rail box. The first lead screw is threadedly connected to the slider. A third servo motor is fixedly mounted on the side of the rail box. The output shaft of the third servo motor is fixedly connected to one end of the first lead screw.

[0010] A fourth servo motor is also fixedly mounted on the second mounting plate, and a transmission pair is connected between the output shaft of the fourth servo motor and the pivot of the rail box.

[0011] A further technical solution: The drug injection mechanism includes a switching motor fixedly mounted on a slider. The output shaft of the switching motor is fixedly mounted on a first mounting plate. A drilling component and a drug injection component are mounted on the first mounting plate. The drilling component and the drug injection component are distributed around the axis of the output shaft of the switching motor.

[0012] A further technical solution: The drilling assembly includes a second servo motor, which is fixedly mounted on a first mounting plate, and a drill bit is fixedly mounted on the output shaft of the second servo motor.

[0013] Further technical solution: The injection assembly includes an injection cylinder, which is fixedly mounted on a first mounting plate. One end of the injection cylinder is connected to an injection needle, and the other end of the injection cylinder is provided with a plug for sealing the injection cylinder. A drug storage tank is fixedly mounted on the mounting bracket, and a drug pump is fixedly mounted on the top of the drug storage tank. The outlet of the drug pump is connected to a flexible tube, one end of which is connected to the injection cylinder. A flow meter and a solenoid valve are provided on the flexible tube, and the inlet of the drug pump extends into the interior of the drug storage tank through a pipe.

[0014] Further technical solution: A positioning mechanism is also installed on the vehicle body. The positioning mechanism includes a fixed cylinder fixedly installed on the vehicle body, a movable rod slidably installed at the bottom of the fixed cylinder, a cone head fixedly connected to the bottom end of the movable rod, a screw rotatably installed on the fixed cylinder, one end of the screw threadedly connected to the movable rod, a connecting plate fixedly connected to the side of the output end of the first linear module, a rack fixedly installed on the connecting plate, a gear fixedly installed at one end of the screw, and the gear and rack meshing together.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In this invention, the vehicle body is first fixed to the tree trunk using a wrapping mechanism. When drilling, the vehicle body is prevented from being pushed away by the tree trunk, thus improving drilling efficiency. Then, the tree trunk is drilled and injected with medicine through an injection mechanism. This avoids manual drilling and injection by workers, thus avoiding the need for workers to squat while working. Workers only need to push the vehicle body close to the tree trunk to achieve automatic drilling and injection, which greatly improves work efficiency.

[0017] 2. In this invention, by setting a positioning mechanism, when the first linear module drives the embracing mechanism to embrace the tree trunk, the first linear module will also drive the rack to move through the connecting plate. The rack drives the movable rod and the cone head to descend, thereby inserting the cone head into the ground to prevent the vehicle body from moving. This solves the problem that the drill bit may drive the vehicle body to rotate around the tree trunk, thereby expanding the drilling area and causing greater damage to the tree trunk, which is not conducive to the continued growth of the tree.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0026] like Figures 1-5 As shown, this invention provides a trunk drilling and injection device for controlling forest pests and diseases, comprising a vehicle body 1, which consists of a frame, handlebars, and casters. A circumferential mechanism 2 is installed on the top of the vehicle body 1, which is used to fix the vehicle body 1 relative to the tree trunk. A mounting frame 4 is fixedly installed on the vehicle body 1, and an adjustment mechanism 9 is installed on the mounting frame 4. An injection mechanism 8 is installed at the output end of the adjustment mechanism 9. The adjustment mechanism 9 is used to adjust the horizontal position, vertical position, and angle of the injection mechanism 8. The injection mechanism 8 is used to drill holes and inject pesticide into the tree trunk.

[0027] In this invention, the vehicle body 1 is first fixed to the tree trunk using the circling mechanism 2. This prevents the vehicle body 1 from being pushed away by the tree trunk during drilling, thus improving drilling efficiency. Then, the injection mechanism 8 is used to drill holes and inject medicine into the tree trunk, eliminating the need for manual drilling and injection by workers. This also eliminates the need for workers to squat while working. Workers only need to push the vehicle body close to the tree trunk to achieve automatic drilling and injection, greatly improving work efficiency.

[0028] This invention provides a trunk drilling and injection device for controlling forest pests and diseases. In this embodiment, the circling mechanism 2 includes two ring arms 26. Two first linear modules 3 are fixedly installed on the vehicle body 1. The two ring arms 26 are respectively fixedly installed on the output ends of the two first linear modules 3. The end of the ring arm 26 away from the vehicle body 1 is hinged to a clamping arm 22. A torsion spring is provided between the clamping arm 22 and the ring arm 26, so that the clamping arm 22 tends to open. The end of the ring arm 26 is provided with a limiting baffle 21 adapted to the clamping arm 22. The circling mechanism 2 also includes two closing mechanisms. The two closing mechanisms are respectively installed on the two ring arms 26. The output end of the closing mechanism is connected to the clamping arm 22. The closing mechanism is used to drive the clamping arm 22 to rotate so that the clamping arm 22 is close to the ring arm 26 for the trunk to pass through.

[0029] Specifically, the distance between the ends of the two ring arms 26 is less than the diameter of the trunk.

[0030] In use, the vehicle body 1 is first brought close to the tree trunk. Then, the two first linear modules 3 drive the two ring arms 26 to move synchronously, so the clamping arm 22 slowly approaches the tree trunk. When the clamping arm 22 touches the tree trunk, the tree trunk will push the clamping arm 22 to rotate towards the ring arm 26. After the clamping arm 22 passes the tree trunk, the torsion spring drives the clamping arm 22 to rebound. Then, the first linear module 3 drives the ring arm 26 to move in the opposite direction, so the clamping arm 22 moves towards the tree trunk again. When the clamping arm 22 touches the tree trunk again, due to the obstruction of the limit baffle 21, the clamping arm 22 cannot rotate outward, so the tree trunk is clamped between the clamping arm 22 and the vehicle body 1, thereby fixing the vehicle body 1 and the tree trunk relatively. When drilling, this prevents the vehicle body 1 from being pushed away by the tree trunk and improves drilling efficiency.

[0031] After the injection is completed, the first linear module 3 drives the ring arm 26 away from the tree trunk, and then the closing mechanism drives the clamping arm 22 to rotate, so that the angle between the clamping arm 22 and the ring arm 26 is reduced, so that the distance between the two clamping arms 22 is greater than the diameter of the tree trunk. Finally, the first linear module 3 drives the ring arm 26 to move towards the vehicle body 1, so that the clamping arm 22 passes over the tree trunk, and then the clamping arm 22 is released, so that the fixation between the vehicle body 1 and the tree trunk can be released.

[0032] The present invention provides a trunk drilling and injection device for the prevention and control of forest tree diseases and pests. In this embodiment, the closing mechanism includes a second mounting groove 27 and a first mounting groove 24 formed on the ring arm 26. A take-up reel 28 is rotatably mounted inside the second mounting groove 27, and a pull rope 23 is wound on the take-up reel 28. A deflector pulley 25 is rotatably mounted inside the first mounting groove 24. The pull rope 23 passes through the ring arm 26 and is fixedly connected to the arm 22 after passing around the deflector pulley 25. A first servo motor 29 is also fixedly mounted on the ring arm 26, and the output shaft of the first servo motor 29 is fixedly connected to one end of the take-up reel 28.

[0033] Specifically, when the clamp arm 22 is closed, the first servo motor 29 is started. The first servo motor 29 drives the take-up reel 28 to rotate. The take-up reel 28 winds the pull rope 23. The pull rope 23 pulls the clamp arm 22 to rotate, which can pull the clamp arm 22 toward the ring arm 26.

[0034] This invention provides a trunk drilling and injection device for controlling forest pests and diseases. In this embodiment, the adjustment mechanism 9 includes a second linear module 99, which is fixedly mounted on a mounting frame 4. An electric telescopic rod 98 is fixedly mounted on the output end of the second linear module 99. A second mounting plate 97 is fixedly mounted on the movable end of the electric telescopic rod 98. A rail box 93 is rotatably mounted on the second mounting plate 97. A slider 92 is slidably mounted inside the rail box 93. A first lead screw 91 is rotatably mounted inside the rail box 93. The first lead screw 91 is threadedly connected to the slider 92. A third servo motor 94 is fixedly mounted on the side of the rail box 93. The output shaft of the third servo motor 94 is fixedly connected to one end of the first lead screw 91.

[0035] A fourth servo motor 96 is also fixedly mounted on the second mounting plate 97. The output shaft of the fourth servo motor 96 is connected to the pivot of the rail box 93 by a transmission pair 95.

[0036] Specifically, the injection mechanism 8 is mounted on the slider 92.

[0037] In use, the second linear module 99 can adjust the horizontal position of the injection mechanism 8, the electric telescopic rod 98 can adjust the vertical position of the injection mechanism 8, and the fourth servo motor 96 drives the rail box 93 to rotate through the transmission pair 95, which can adjust the angle of the injection mechanism 8 to achieve the adjustment of different injection positions for different trees.

[0038] During injection, the second linear module 99 first drives the injection mechanism 8 closer to the tree trunk. Then, the electric telescopic rod 98 and the fourth servo motor 96 adjust the vertical height and angle of the injection mechanism 8. Finally, the third servo motor 94 drives the slider 92 to move, so that the slider 92 drives the injection mechanism 8 closer to the tree trunk to achieve drilling and injection.

[0039] The present invention provides a trunk drilling and injection device for the prevention and control of forest tree diseases and pests. In this embodiment, the injection mechanism 8 includes a switching motor 87 fixedly installed on a slider 92. The output shaft of the switching motor 87 is fixedly installed on a first mounting plate 83. A drilling component and an injection component are installed on the first mounting plate 83. The drilling component and the injection component are distributed around the axis of the output shaft of the switching motor 87.

[0040] Specifically, first, the output end of the drilling component is aligned with the tree trunk, and the drilling component is activated. Then, the third servo motor 94 drives the slider 92 to move. The slider 92 drives the switching motor 87 and the drilling component to approach the tree trunk. The drilling component will drill a hole in the tree trunk. Then, the third servo motor 94 drives the first lead screw 91 to reverse. The first lead screw 91 drives the drilling component to retract through the slider 92, so that the output end of the drilling component is pulled out of the hole. Then, the switching motor 87 drives the first mounting plate 83 to rotate so that the output end of the injection component is aligned with the tree hole. Then, the third servo motor 94 drives the injection component to move so that the output end of the injection component extends into the hole, completing the injection.

[0041] The present invention provides a trunk drilling and injection device for the prevention and control of forest tree diseases and pests. In this embodiment, the drilling component includes a second servo motor 82, which is fixedly installed on a first mounting plate 83, and a drill bit 81 is fixedly installed on the output shaft of the second servo motor 82.

[0042] This invention provides a trunk drilling and injection device for controlling forest pests and diseases. In this embodiment, the injection assembly includes an injection cylinder 85, which is fixedly mounted on a first mounting plate 83. One end of the injection cylinder 85 is connected to an injection needle 86, and the other end of the injection cylinder 85 is provided with a plug 84 for sealing the injection cylinder 85. A medicine storage tank 812 is fixedly mounted on the mounting frame 4, and a medicine pump 811 is fixedly mounted on the top of the medicine storage tank 812. The outlet of the medicine pump 811 is connected to a hose 88, one end of which is connected to the injection cylinder 85. A flow meter 89 and a solenoid valve 810 are provided on the hose 88, and the inlet of the medicine pump 811 extends into the interior of the medicine storage tank 812 through a pipe.

[0043] Specifically, the distance from the end of the drill bit 81 to the axis of the switching motor 87 is equal to the distance from the end of the injection needle 86 to the axis of the switching motor 87.

[0044] The medicine storage tank 812 is also equipped with a dosing pipe and a discharge pipe.

[0045] When in use, first insert the injection needle 86 into the drilled hole, then open the solenoid valve 810 and start the medicine pump 811. The medicine pump 811 draws the medicine liquid in the medicine storage tank 812 and delivers it to the injection cylinder 85, and injects it into the tree trunk through the injection needle 86. The flow meter 89 detects the flow rate of the medicine liquid. When the injection volume is sufficient, immediately close the solenoid valve 810 and stop the medicine pump 811.

[0046] It is worth noting that when using the device for the first time, the syringe 85 needs to be filled with medication until medication leaks from the tip of the injection needle 86, and then normal medication injection can begin.

[0047] This invention provides a trunk drilling and injection device for controlling forest pests and diseases. Since the trunk is circular, the contact between the arm 22 and the vehicle body 1 and the trunk is point contact. After the drill bit 81 interacts with the trunk, the drill bit 81 may cause the vehicle body 1 to rotate around the trunk, thereby increasing the drilling area and causing further damage to the trunk, which is detrimental to the continued growth of the tree. Therefore, in this embodiment, a positioning mechanism 7 is also installed on the vehicle body 1. The positioning mechanism 7 includes a fixed cylinder 74 fixedly installed on the vehicle body 1. A movable rod 75 is slidably installed at the bottom of the fixed cylinder 74. A cone head 76 is fixedly connected to the bottom end of the movable rod 75. A screw 73 is rotatably installed on the fixed cylinder 74. One end of the screw 73 is threadedly connected to the movable rod 75. A connecting plate 6 is fixedly connected to the side of the output end of the first linear module 3. A rack 71 is fixedly installed on the connecting plate 6. A gear 72 is fixedly installed at one end of the screw 73. The gear 72 and the rack 71 are meshed together.

[0048] Specifically, when the first linear module 3 drives the embracing mechanism 2 to embrace the tree trunk, the first linear module 3 will also drive the rack 71 to move through the connecting plate 6. The rack 71 drives the movable rod 75 and the cone 76 to descend, thereby inserting the cone 76 into the ground to prevent the vehicle body 1 from moving. This solves the problem that the drill bit 81 may drive the vehicle body 1 to rotate around the tree trunk, thereby expanding the drilling area and causing greater damage to the tree trunk, which is not conducive to the continued growth of the tree.

[0049] In addition, multiple positioning mechanisms 7 can be set up to make the vehicle body 1 more stable and minimize damage to the tree trunk.

[0050] The present invention provides a trunk drilling and injection device for the prevention and control of forest pests and diseases. In this embodiment, the first linear module 3 and the second linear module 99 have the same structure, both including a slide rail, a slide block, a second lead screw and a fifth servo motor. The slide block is slidably installed on the slide rail, and the second lead screw is fixedly installed on the fifth servo motor. The second lead screw and the slide block are threadedly connected.

[0051] The connecting plate 6 is fixedly connected to the slide of the first linear module 3, and the electric telescopic rod 98 is fixedly installed on the slide of the second linear module 99.

[0052] Working principle:

[0053] The vehicle body 1 is pushed close to the tree trunk to be injected with medicine. The first linear module 3 drives the two ring arms 26 to move synchronously, so that the clamping arm 22 slowly approaches the tree trunk. After the clamping arm 22 passes the tree trunk, the first linear module 3 drives the ring arms 26 to move in the opposite direction, so that the tree trunk is clamped between the clamping arm 22 and the vehicle body 1, thereby fixing the vehicle body 1 and the tree trunk relatively. At the same time, the first linear module 3 drives the connecting plate 6 to move, the connecting plate 6 drives the rack 71 to move, the rack 71 drives the movable rod 75 and the cone 76 to descend, so that the cone 76 is inserted into the ground, completing the fixation of the vehicle body 1.

[0054] During injection, the second linear module 99 first moves the drill bit 81 closer to the tree trunk. Then, the electric telescopic rod 98 and the fourth servo motor 96 adjust the height and angle of the drill bit 81 respectively. Finally, the third servo motor 94 moves the drill bit 81 so that its end abuts against the tree trunk. The second servo motor 82 is then activated, causing the drill bit 81 to rotate. Simultaneously, the third servo motor 94 is activated, causing the drill bit 81 to extend into the tree trunk. After drilling is completed, the third servo motor 94 is reversed, causing the drill bit 81 to rotate. 1. Reverse the flow. After the drill bit 81 exits the hole, start the switching motor 87. The switching motor 87 drives the first mounting plate 83 and the injection cylinder 85 to rotate until the axis of the injection needle 86 coincides with the axis of the hole. Then, start the third servo motor 94 again. The third servo motor 94 drives the injection needle 86 to insert into the hole. Then, start the medicine pump 811. The medicine pump 811 draws the medicine liquid in the medicine storage tank 812 and delivers it to the injection cylinder 85. It is then injected into the trunk through the injection needle 86. The flow meter 89 detects the flow rate of the medicine liquid. When the injection volume is sufficient, immediately close the solenoid valve 810 and stop the medicine pump 811.

[0055] After the injection is completed, the first linear module 3 moves the clamping arm 22 away from the tree trunk, and then the first servo motor 29 is started. The first servo motor 29 drives the take-up reel 28 to rotate, and the take-up reel 28 winds up the pull rope 23. The pull rope 23 drives the clamping arm 22 to rotate, reducing the angle between the clamping arm 22 and the ring arm 26. When the distance between the two clamping arms 22 is greater than the diameter of the tree trunk, the first linear module 3 drives the ring arm 26 to move towards the vehicle body 1, so that the clamping arm 22 passes over the tree trunk and is released. This releases the fixation between the vehicle body 1 and the tree trunk. At the same time, the cone head 76 is pulled out of the ground. Repeating the above operation allows for the injection of medicine onto subsequent tree trunks. With the help of the controller and sensors, automatic fixing, drilling, and injection can be achieved, making it more convenient to use.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
