Description

Technical Field

[0001] This utility model relates to the field of plant maintenance technology, and in particular to the maintenance of trees, specifically a device for treating tree diseases and pests. Background Technology

[0002] Due to environmental factors, large-scale insect infestations on trees occur frequently, resulting in low tree survival rates. Pests and diseases have become an important factor affecting tree survival rates.

[0003] Traditional methods for treating tree diseases and pests involve spraying or spreading pesticides on the trees. However, this method has many drawbacks, such as the inability of the pesticide solution to be fully absorbed by the plant and its susceptibility to weather conditions, which can lead to pesticide loss.

[0004] With the development of technology, injection methods are increasingly being used to treat tree diseases and pests. This involves injecting systemic drugs into specific parts of the tree trunk using syringes, allowing the tree to control diseases and pests through its own transpiration. This method is not affected by climate or environmental factors and is considered a relatively ideal drug application technique.

[0005] However, because the wood is relatively hard, the injection needle cannot be inserted directly. It is necessary to drill a hole at the injection site first, and then inject the medicine using a pressurized or gravity-flow method.

[0006] Currently, drilling and pesticide injection in trees are primarily done manually. First, a drilling tool is used to drill a hole, and then the pesticide injection device is operated to inject the pesticide. This process is time-consuming, labor-intensive, and physically demanding. Furthermore, because the drilling direction needs to be inclined and cannot be perpendicular to the tree, the difficulty of manual drilling is increased. Utility Model Content

[0007] This invention addresses the shortcomings of existing technologies by providing a device for treating tree diseases and pests. It can replace manual drilling and pesticide injection, reducing labor intensity and operational difficulty, and increasing the difficulty of treating diseases and pests.

[0008] This utility model is achieved through the following technical solution: a device for treating tree diseases and pests is provided, including a frame and an injection unit installed on the frame. The injection unit includes an inclined support rail, a first driving device for driving the support rail to rotate around its length axis, and an injection assembly and a drilling assembly installed on the support rail.

[0009] The drug injection assembly includes a drug injection needle connected to a drug storage tank, the drug injection needle being parallel to the axis of the support track along its length; the drilling assembly includes a drill bit, a drilling motor for driving the drill bit to rotate, and a first slide fixed to the drilling motor and movable along the length of the support track, the drill bit and the drug injection needle being circumferentially distributed around the axis of the support track along its length.

[0010] This design mounts the injection and drilling components on the same frame, improving stability during drilling and injection. The rotation of the support rail allows for position switching between the two components. The drill bit is fed and retracted by the movement of the first slide along the support rail, drilling injection holes in the trees. After the drill bit exits the injection hole, the rotation of the support rail moves the injection needle to the hole for injection. This not only achieves drilling and injection but also ensures the accuracy of the relative position of the injection needle and the injection hole.

[0011] As an optimization, the frame is further equipped with a support platform and a telescopic mechanism for driving the support platform to move toward the tree. A first support rod and a second support rod located in front of the first support rod are fixedly mounted on the support platform. An upper rotating shaft, rotatably connected to the first support rod, is fixedly connected to the upper end of the support track, and a lower rotating shaft, rotatably connected to the second support rod, is fixedly connected to the lower end of the support track. This optimized solution achieves support for the support track by setting the upper and lower rotating shafts, and facilitates the rotation of the support track, resulting in a simple structure. By setting a telescopic mechanism to drive the support platform to move back and forth, the support platform can be retracted when injection is not needed, reducing space occupation; when injection is needed, the support platform can be pushed forward toward the tree for drilling and injection operations.

[0012] As an optimization, the first support rod includes a lower rod body fixedly connected to the support platform, and an upper rod body extending upwardly at the upper end of the lower rod body. The upper end of the upper rod body has a U-shaped groove adapted to the upper rotating shaft. The first driving device includes a first motor fixedly mounted on the top of the upper rod body, and the output shaft of the first motor is coaxially fixedly connected to the upper rotating shaft. This optimized first support rod structure is simple. The U-shaped groove facilitates the installation of the support rail, and the upper rod body's inclination towards the side where the support rail is located improves the stability of the support for the first motor and also increases the strength of the first support rod.

[0013] As an optimization, a clamping unit is installed at the end of the support platform facing the tree. The clamping unit includes a first arc-shaped clamping member and a second arc-shaped clamping member arranged opposite each other, forming a clamping space adapted to the tree. The ends of the first and second arc-shaped clamping members away from the tree are rotatably connected to the support platform. A second driving device is installed on the support platform to drive the first and second arc-shaped clamping members to rotate and open / close. This optimized solution, by setting up the clamping unit, clamps the tree trunk with the first and second arc-shaped clamping members before drilling, keeping the entire device stationary during drilling and pesticide injection, thus improving the drilling and pesticide injection efficiency.

[0014] As an optimization, two of each of the first and second arc-shaped clamping components are used. The two first and two second arc-shaped clamping components are arranged vertically, with the upper first and second arc-shaped clamping components facing each other to form a clamping space, and the lower first and second arc-shaped clamping components also facing each other to form a clamping space. This optimized design increases the clamping length range for trees, improves the overall stability of the device, avoids significant vibrations during drilling operations, and ensures drilling efficiency.

[0015] As an optimization, two first arc-shaped clamping members are fixedly mounted on the first vertical shaft and rotatably connected to the support platform through the first vertical shaft. Two second arc-shaped clamping members are fixedly mounted on the second vertical shaft and rotatably connected to the support platform through the second vertical shaft. The second driving device includes a second motor and a drive gear fixedly mounted on the output shaft of the second motor. At least one first arc-shaped clamping member has a first gear tooth segment that meshes with the drive gear and is centered on the axis of the first vertical shaft. At least one second arc-shaped clamping member has a second gear tooth segment that meshes with the first gear tooth segment and is centered on the axis of the second vertical shaft. This optimization drives the drive gear to rotate through the second motor. The meshing of the drive gear with the first gear tooth segment drives the two first arc-shaped clamping members to rotate. The meshing of the first gear tooth segment and the second gear tooth segment on the first arc-shaped clamping member drives the second arc-shaped clamping member to rotate. This achieves simultaneous relative or opposite rotation of the first and second arc-shaped clamping members, i.e., the rotational opening and closing of the first and second arc-shaped clamping members.

[0016] As an optimization, a first wheel, a first gear, and a third motor driving the first gear to rotate are mounted on the first slide. A first rack meshing with the first gear and extending along its length, and a first concave track groove adapted to the first wheel are provided on the support rail. The first wheel and the first gear are arranged laterally. This optimized solution utilizes the first wheel and the first gear clamped on the support rail, with the first wheel engaged in the first concave track groove. The third motor drives the first gear to rotate, and the meshing action of the first gear and the first rack causes the first slide to drive the drilling motor to move along the length of the support rail, achieving drill bit feeding and retraction, forming an injection hole.

[0017] As an optimization, the support rail is provided with a second slide that moves along its length. The second slide is fixedly connected to the injection needle. A second wheel, a second gear, and a fourth motor that drives the second gear are also mounted on the second slide. The support rail is provided with a second rack that meshes with the second gear and extends along its length, and a second concave track groove adapted to the second wheel. The second wheel and the second gear are arranged laterally. This optimized solution utilizes the second wheel and the second gear clamped on the support rail, with the second wheel engaged in the second concave track groove. The fourth motor drives the second gear to rotate, and the meshing of the second gear and the second rack causes the second slide to move the injection needle along the length of the support rail, enabling the injection needle to enter and exit the injection hole drilled by the drill bit.

[0018] As an optimization, the cross-section of the support track is rectangular, and the injection assembly and drilling assembly are respectively set on two opposite sidewalls of the support track. This optimized solution sets the support track as a rectangular body, which facilitates the setting of the rack and the concave track groove. The relative positions of the injection assembly and the drilling assembly can be switched by rotating the support track 180 degrees, while improving the stability of the support track during rotation.

[0019] As an optimization, a tracked chassis is also included, on which a base plate is mounted and fixedly connected to the frame. The liquid medicine storage tank is supported and fixed on the base plate and located inside the frame. This optimized solution, by using a tracked chassis, facilitates the overall movement of the device and increases the friction with the ground, ensuring the stability of drilling; by placing the liquid medicine storage tank inside the frame, space is saved.

[0020] The beneficial effects of this utility model are as follows: by setting the injection component and the drilling component on an inclined support rail, the position switching of the drill bit and the injection needle can be completed by rotating the support rail, and inclined drilling can be achieved. Moreover, there is no need for manual holding of the drill and the injection needle to perform drilling and injection operations, which greatly reduces labor intensity. Furthermore, drilling and injection are quickly connected through the rotating support rail, which greatly improves the efficiency of drilling and injection. Attached Figure Description

[0028] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to describe the solution.

[0029] like Figure 1 The device for treating tree diseases and pests includes a tracked chassis 3, a frame 1, and an injection unit mounted on the frame. A top plate is fixed to the top of the frame. A base plate 2, fixed to the frame, is mounted on the tracked chassis. A main control box 35 and a pesticide storage tank 36 are supported and fixed on the base plate. A pesticide storage tank 36 is used to transfer the pesticide to the injection unit. Both the pesticide storage tank 36 and the main control box 35 are located inside the frame, which reduces the overall space occupied by the machine. The machine moves by moving the tracked chassis, and the structure of the tracked chassis can be achieved using existing technology. By using the tracked chassis, the overall stability of the machine is improved during drilling and pesticide injection.

[0030] The injection unit includes an inclined support rail 14, a first drive device 16 that drives the support rail to rotate about its length axis, and an injection assembly and a drilling assembly mounted on the support rail, which are distributed circumferentially along the support rail. The vertical projection of the upper end of the support rail is located behind the vertical projection of the lower end of the support rail. As the injection assembly and drilling assembly move down along the support rail, drilling and injection are completed.

[0031] The injection assembly includes an injection needle 26 connected to a liquid storage tank 36, and a water pump 28 located between the liquid storage tank 36 and the injection needle 26. The water pump inlet is connected to the liquid storage tank 36 via a second injection hose 29, and the water pump outlet is connected to the injection end of the injection needle 26 via a first injection hose 27. The injection needle 26 is parallel to the axis along the length of the support track, and the injection end of the injection needle faces the tree.

[0032] The drilling assembly includes a drill bit 19, a drilling motor 20 that drives the drill bit to rotate, and a first slide 22 fixed to the drilling motor and movable along the length direction of the support track. The drill bit 19 and the injection needle 26 are circumferentially distributed around the axis of the support track. The drill bit and the injection needle are parallel, and the distance from the drill bit to the axis of the support track is equal to the distance from the injection needle to the axis of the support track, ensuring the accuracy of the relative position between the injection hole drilled by the drill bit and the injection needle. In this embodiment, the drill bit is mounted on a drill bit connector, and the drill bit connector is mounted on the drilling motor.

[0033] The first slide 22 is equipped with a first wheel 25, a first gear 24, and a third motor 23 that drives the first gear to rotate. The third motor is a stepper motor. The support rail is provided with a first rack that meshes with the first gear and extends along its length, and a first concave track groove that matches the first wheel. The first wheel is engaged in the first concave track groove and moves along the first concave track groove. The first wheel and the first gear are arranged laterally, and the axes of the first wheel and the first gear are perpendicular to the length axis of the support rail. The drilling assembly is secured on the support rail by the first wheel and the first gear and moves along the support rail. To improve the stability of the drilling assembly's movement, two first wheels are provided, and the arrangement direction of the two first wheels is parallel to the drill bit axis. To facilitate the installation of the drilling motor 20, a right-angle bracket 21 is fixed to the first slide. One side of the right-angle bracket is fitted and fixed to the first slide, and the other side of the right-angle bracket has a through hole for the output shaft of the drilling motor to pass through. A bearing that matches the output shaft of the drilling motor is fixed in the through hole. By setting up right-angle brackets, the side of the right-angle brackets provides support for the output shaft of the drilling motor, reducing drill bit runout during drilling.

[0034] A second slide 31, which moves along the length of the support rail, is fixedly connected to the injection needle tube 26. A second wheel 34, a second gear 33, and a fourth motor 32 (a stepper motor) driving the second gear are also mounted on the second slide. The support rail has a second rack that meshes with the second gear and extends along its length, and a second concave track groove adapted to the second wheel. The second wheel is engaged in the second concave track groove and moves along it. The second wheel and the second gear are arranged laterally, and the axes of the second wheel 34 and the second gear 33 are perpendicular to the length axis of the support rail. The second wheel and the second gear secure the entire injection assembly to the support rail, allowing it to move along the rail. To improve the stability of the injection assembly's movement, two second wheels 34 are provided, and their arrangement is parallel to the axis of the injection needle tube. To facilitate the fixation of the injection needle, in this embodiment, a mounting plate 30 is fixed on the second slide. The mounting plate is perpendicular to the axis of the support track in the length direction, and the injection needle 26 is fixed on the mounting plate 30.

[0035] The cross-section of the support rail in this embodiment is square. The injection assembly and the drilling assembly are respectively set on two opposite side walls of the support rail. By rotating the support rail 180 degrees, the positions of the injection needle and the drill bit can be switched. Anti-detachment baffles 17 are fixed at the upper and lower ends of the support rail 14. An anti-detachment strip 18 is fixed on the side where the drilling assembly and the injection assembly are located. The two ends of the anti-detachment strip 18 are fixed to the upper and lower anti-detachment baffles 17 respectively. A limiting hole is formed between the anti-detachment strip and the support rail. The first slide and the second slide are both plate structures. The first slide and the second slide pass through the limiting hole on their respective sides and move along the limiting hole. The anti-detachment strip prevents the first slide and the second slide from falling off the support rail.

[0036] The frame is also equipped with a support platform 5 and a telescopic mechanism that drives the support platform 5 to move toward the tree. The support platform has slide rails 6 fixed to the top plate of the frame on its left and right sides, providing guidance for the movement of the support platform. In this embodiment, the telescopic mechanism is an electric push rod 4, which extends and retracts in the front-back direction. A first support rod 7 and a second support rod 8 located in front of the first support rod are fixed on the support platform. The height of the second support rod is less than the height of the first support rod. An upper rotating shaft, rotatably connected to the first support rod 7, is fixed to the upper end of the support rail, and a lower rotating shaft, rotatably connected to the second support rod 8, is fixed to the lower end of the support rail. The axes of both the upper and lower rotating shafts coincide with the axis of the length direction of the support rail. When the electric push rod extends and retracts, it drives the support platform to move back and forth, thereby driving the injection unit to move back and forth. When drilling and injecting medicine into trees, the tracked chassis moves forward until the distance between the front of the vehicle and the trunk is within 50 cm. The support rods of the two injection units form a certain height difference, and the tilt angle of the injection unit forms an angle of 40° to 45° with the trunk.

[0037] The first support rod 7 includes a lower rod body fixedly connected to the support platform, and an upper rod body extending upwardly at the upper end of the lower rod body. The upper end of the upper rod body has a U-shaped groove adapted to the upper rotating shaft. The first drive device 16 includes a first motor fixedly mounted on the top of the upper rod body. The first motor is a stepper motor, and its output shaft is coaxially fixedly connected to the upper rotating shaft. The second support rod has a groove adapted to the lower rotating shaft. In this embodiment, to facilitate the installation of the first motor, a connecting block 15 is provided between the first motor and the upper rod body. The connecting block has a through hole for the output shaft of the first motor and the upper rotating shaft to pass through. The bottom surface of the connecting block is fixedly connected to the upper rod body, and the first motor is fixed to the top surface of the connecting block.

[0038] A clamping unit is installed at the end of the support platform facing the tree. This clamping unit holds the tree trunk, improving the overall stability of the machine. The clamping unit is located in front of the injection unit in the front-to-back direction and below the injection unit in the vertical direction. When the clamping unit holds the tree trunk, the injection unit is in the working position.

[0039] Specifically, the clamping unit includes a first arc-shaped clamping member 12 and a second arc-shaped clamping member 13 arranged opposite to each other. A clamping space adapted to the tree is formed between the first arc-shaped clamping member 12 and the second arc-shaped clamping member 13. The ends of the first arc-shaped clamping member and the second arc-shaped clamping member away from the tree are respectively rotatably connected to the support platform through a vertical shaft. A second driving device 10 is installed on the support platform to drive the first arc-shaped clamping member and the second arc-shaped clamping member to rotate and open and close.

[0040] To increase the clamping length range of the tree trunk and further improve stability, this embodiment uses two first arc-shaped clamping members 12 and 13. The two first arc-shaped clamping members and the two second arc-shaped clamping members are arranged vertically. The upper first arc-shaped clamping member and the upper second arc-shaped clamping member are positioned opposite each other to form a clamping space, and the lower first arc-shaped clamping member and the lower second arc-shaped clamping member are also positioned opposite each other to form a clamping space. The vertical projections of the two first arc-shaped clamping members coincide, and the vertical projections of the two second arc-shaped clamping members coincide.

[0041] To better achieve the drive opening and closing, two first arc-shaped clamping members 12 are fixedly mounted on the first vertical shaft and rotatably connected to the support platform 5 through the first vertical shaft. Two second arc-shaped clamping members are fixedly mounted on the second vertical shaft and rotatably connected to the support platform through the second vertical shaft. The second drive device 10 includes a second motor and a drive gear 11 fixedly mounted on the output shaft of the second motor. The second motor is a stepper motor. At least one first arc-shaped clamping member has a first gear segment that meshes with the drive gear and is centered on the axis of the first vertical shaft. At least one second arc-shaped clamping member has a second gear segment that meshes with the first gear segment and is centered on the axis of the second vertical shaft. In this embodiment, the first gear segment of the upper first arc-shaped clamping member meshes with the drive gear and simultaneously meshes with the second gear segment of the upper second arc-shaped clamping member. The first gear segment of the lower first arc-shaped clamping member meshes with the second gear segment of the lower second arc-shaped clamping member, ensuring the stability of the clamping unit's opening and closing. When the second motor rotates, it drives the drive gear to rotate, which in turn drives the first arc-shaped clamping member to rotate. Simultaneously, the first arc-shaped clamping member drives the second arc-shaped clamping member to rotate, thus enabling the first and second arc-shaped clamping members to rotate relative to or opposite to each other. This allows the clamping unit to open and close, and can clamp tree trunks of different diameters.

[0042] To facilitate the installation of the second drive device 10, in this embodiment, a hollow connecting frame 9 is fixed at the front end of the support platform. The second drive device, the first vertical shaft, and the second vertical shaft are all installed on the connecting frame 9. The second motor is located inside the connecting frame, the drive gear 11 is located above the connecting frame, and the connecting frame is located between the upper first arc-shaped clamping member and the lower first arc-shaped clamping member.

[0043] In this embodiment, the first motor 16 can drive the support rail 14 to rotate forward and backward, and the rotation angle can be fixed. The drilling motor can drive the drill bit to rotate. The third motor 23 can drive the drilling assembly to reciprocate. The water pump can deliver the medicine. The fourth motor 32 can drive the injection assembly to reciprocate. The height of the drill bit to the support rail is the same as the height of the injection needle to the support rail.

[0044] The working process of this embodiment is as follows: When not in operation, both the drilling assembly and the injection assembly are in their original positions. When in operation, the third motor 23 and the drilling motor 20 start simultaneously. The drilling assembly moves towards the tree trunk until it contacts the trunk and drills to a certain depth, forming an injection hole. The depth of the injection hole is determined according to the diameter of the tree trunk, generally 3-8 cm. When drilling is completed, the drilling assembly moves away from the tree trunk. When the drilling assembly reaches its initial position, the third motor and the drilling motor stop. At this time, the first motor starts, driving the support rail to rotate 180° clockwise. The position of the injection component is consistent with the initial position of the drilling component. At this time, the fourth motor 32 starts, and the injection component moves towards the trunk. When the injection needle head contacts the injection hole and penetrates a certain distance, the fourth motor stops, and the water pump starts to work. The water pump transports a metered amount of medicine into the injection needle through the hose, and the medicine flows into the trunk hole. After the medicine is transported, the water pump stops working, the fourth motor starts, and the injection component moves away from the trunk. When the injection component moves to the initial position, the fourth motor stops. At this time, the first stepper motor starts, driving the support track to rotate 180°.

[0045] This invention utilizes a main control box to control the operation of each motor, automating the drilling and injection of pesticides into trees, significantly reducing the labor intensity of workers. The injection unit employs a controllable motor-driven water pump for quantitative injection and is equipped with a controllable motor and drill bit for automatic drilling with adjustable depth, resulting in high efficiency.
