Description

Technical Field

[0001] The invention relates to the technical field of forestry pest control, in particular to a perforating and injecting device for forestry pest control. Background Art

[0002] The use of pesticides is suitable for the prevention and control of forest pests. Forests are important economic resources. Pests and diseases will lead to a decrease in timber production and affect the forestry economy. Through pesticide control, the economic losses caused by pests and diseases can be reduced. Forest pests and diseases may also destroy the biodiversity of the forest and affect the stability of the ecosystem. Some forest pests and diseases may trigger chain reactions, such as causing natural disasters such as landslides and mud-rock flows. Through pesticide control, these disasters can be prevented.

[0003] Chinese patent CN202411221128.0 discloses a drilling and injection device for forestry pest control, including an arc frame, a positioning block is fixedly connected to the end of the arc frame, a fixing component is arranged on the surface of the positioning block, a support plate is fixedly connected to the surface of the arc frame, a cylindrical rod is fixedly connected to the inner wall of the support plate, a drilling component is arranged on the surface of the support plate, an injection component is arranged on the top of the drilling component, and a stabilizing component is arranged on the top of the arc frame.

The side brackets 102 are fixedly arranged on both sides of the tank shell 101, and the side guide grooves 103 are arranged in the side brackets 102. The main shaft rod 104 is rotatably arranged on the tank shell 101 and two sets of driving screw rods are arranged at both ends of the main shaft rod 104. Rod 105; clamp arm assembly 2, the clamp arm assembly 2 includes a sliding base 201, a clamping arm 202, a limiting guide rod 203 and a clamping shell 204, the sliding base 201 is limited and slidably assembled on the side guide groove 103, and one end of the sliding base 201 is fixedly connected to the clamping arm 202, and a plurality of limiting guide rods 203 are arranged on the clamping arm 202, one end of the clamping shell 204 is elastically slidably assembled on the limiting guide rod 203, and the other end of the clamping shell 204 is slidably inserted in The clamping arm 202; the injection assembly 4, the injection assembly 4 includes an injection shell 401, an inner guide rod 402, a drill base plate 403 and a drill 404, the injection shell 401 is slidably assembled in the tank housing 101, the injection shell 401 is fixedly provided with an inner guide rod 402, the two groups of drill base plates 403 are limitedly slidably assembled on the inner guide rod 402 and the two groups of drill base plates 403 are fixedly connected, and one end of the drill 404 is rotatably assembled on the drill base plate 40 3, the other end of the drill bit 404 is arranged toward one side of the two groups of clamping shells 204; the perforating and injecting device for forestry pest control has a relative first direction x, a second direction y and a third direction z, the two groups of sliding bases 201 are slidably assembled on the side guide groove 103 along the first direction x, the two groups of clamping shells 204 are slidably assembled on the limiting guide rod 203 along the first direction x, and the injection shell box 401 is slidably assembled in the groove shell 101 along the second direction y.

[0034] In actual application of this embodiment, the device has two states during actual use: an open state and a locked state. In the open state, the two groups of sliding bases 201 are respectively located at the farthest positions of the two groups of side guide grooves 103. At this time, the spacing between the two groups of clamping arms 202 in the first direction x reaches a maximum value. At this time, the tree trunk to be injected with medicine is moved between the two groups of clamping arms 202 through an external traction setting and / or manual operation. At this time, the main shaft 104 is driven to rotate by an external driving source, which synchronously drives the driving screws 105 at both ends of the main shaft 104 to rotate, and the screws of the two groups of driving screws 105 are rotated. The two driving screw rods 105 are respectively meshed with the two sliding bases 201 to make the two sliding bases 201 move in opposite directions in the first direction x. When the two sliding bases 201 approach each other in the first direction x, the device changes from the open state to the locked state. Since the clamping shell 204 elastically extends in a non-contact state, when the two clamping arms 202 approach each other, the two clamping shells 204 preferably abut against the surface of the trunk. In addition, during the continuous movement, the clamping shell 204 continuously slides relative to the clamping arm 202, so that the elastic sleeve on the limit guide rod 203 The spring is in a state of continuous energy storage, so that the clamping shell 204 can continuously clamp the trunk during the movement, and the clamping shell 204 is linked to the injection shell box 401. When the two sets of sliding bases 201 approach each other so that the distance between the two sets of clamping arms 202 in the first direction x reaches a minimum, the injection device switches from an open state to a locked state, and the clamping shells 204 on the clamping arms 202 stop moving at the same time. At this time, the distance between the two sets of clamping shells 204 is the trunk diameter, so that the injection shell box 401 linked to the clamping shell 204 moves synchronously in the second direction y, and The movement distance of the injection shell box 401 in the second direction y is linearly related to the sliding distance of the clamping shell 204 relative to the clamping arm 202. The displacement of the injection shell box 401 in the second direction y can be adaptively adjusted according to the diameter of the trunk, and the distance between the drill bit 404 and the trunk can be further adjusted, thereby adjusting the drilling depth, so that the medicine to be injected can penetrate the bark and be accurately delivered to the trunk, which is convenient for injecting medicine into trunks of different diameters. At the same time, it can also be automatically locked on the trunk, eliminating the tedious steps of manual positioning and clamping. After the injection of the preventive and control agent, it can also be automatically unlocked and reset, which is convenient for repeated injection of the agent.

[0035] See also Figure 2 and Figure 4In a preferred embodiment of the present invention, the clamping arm assembly 2 also includes a serrated surface 205, a side tooth plate 206, a first transmission gear 207, a transmission shaft 208, a second transmission gear 209 and a third transmission wheel 210. The serrated surface 205 is arranged on the side of the clamping shell 204 facing the trunk. The side tooth plate 206 is fixedly assembled at one end of the clamping shell 204. The first transmission gear 207 and the transmission shaft 208 are both axially arranged at one end of the clamping arm 202. One end of the first transmission gear 207 is meshed with the side tooth plate 206, and the other end of the first transmission gear 207 is transmission-connected with the transmission shaft 208. The transmission shaft 208 is also coaxially fixedly assembled with a second transmission gear 209 and a third transmission wheel 210.

[0036] In actual application of this embodiment, the end of the clamping shell 204 is provided with a serrated surface 205, and the serrated surface 205 is used to abut the surface of the tree trunk. The serrated layer increases the friction between the device and the tree trunk, thereby preventing the device from axially rotating relative to the tree trunk during the drilling process, thereby avoiding damage to the drill bit 404. The first transmission gear 207 and the transmission shaft 208 are fixedly arranged on one side of the clamping arm 202. When the clamping shell 204 slides along the first direction x, the side tooth plate 206 at one end of the clamping shell 204 is synchronously engaged with the first transmission gear 207, thereby driving the first transmission gear 207 to rotate on a fixed axis. The first transmission gear 207 rotates during the rotation process. , further driving the transmission shaft 208 to rotate, so that the second transmission gear 209 can engage and drive the auxiliary clamping arm 301 to slide during the rotation, so that when the device is adjusted from the open state to the locked state, the two groups of clamping arms 202 approach each other to clamp the trunk, and the auxiliary clamping arms 301 at the ends of the two groups of clamping arms 202 can push the trunk to the side of the trough shell 101 during the movement, so that when the device is switched to the locked state, the trough shell 101, the clamping shell 204 and the auxiliary clamping arm 301 are simultaneously in contact with the surface of the trunk to achieve the locking action, eliminating the tedious steps of manual positioning and clamping, and after the injection is completed, it can also be automatically unlocked and reset.

[0037] Furthermore, the transmission ratio between the first transmission gear 207 and the second transmission gear 209 can be freely adjusted by adjusting the diameter of the transmission wheel.

[0038] See also Figure 3 and Figure 4In a preferred embodiment of the present invention, the perforating and injecting device for forestry pest control also includes an auxiliary clamping arm assembly 3, the auxiliary clamping arm assembly 3 includes an auxiliary clamping arm 301, an auxiliary tooth surface 302, a limiting surface 303 and a limiting groove 304, the auxiliary clamping arm 301 is slidably assembled on the clamping arm 202, and one end of the auxiliary clamping arm 301 is provided with an auxiliary tooth surface 302, the auxiliary tooth surface 302 is meshed with the second transmission gear 209, and the other end of the auxiliary clamping arm 301 is provided with a limiting surface 303, one end of the limiting groove 304 is fixedly assembled on the clamping arm 202, and the other end of the limiting groove 304 is limitedly slidably connected with the limiting surface 303.

[0039] In actual application of this embodiment, the auxiliary clamping arm 301 is slidably assembled on the limiting groove 304 through the limiting surface 303, and the limiting groove 304 is fixedly set on the clamping arm 202. Therefore, when the second transmission gear 209 rotates counterclockwise along the xoy plane in the driving state, the auxiliary clamping arm 301 slides toward the trunk side under the meshing action, so that the end of the auxiliary clamping arm 301 abuts against the trunk end. Since the force is mutual, the trunk continues to approach one side of the trough shell 101, and the surface of the trunk is attached to the hollow groove on one side of the trough shell 101, and the drill bit 404 is aimed at the trunk to be injected.

[0040] Furthermore, when the device is in an open state, the two groups of auxiliary clamping arms 301 slide and retract to one side of the clamping arm 202, and when in a retracted state, there is no mechanical interference between the auxiliary clamping arms 301 and the tree trunk, so that the tree trunk can be moved out from between the two groups of clamping arms 202, and then disengaged from the locked state. When the device is in a locked state, the two groups of auxiliary clamping arms 301 continuously squeeze the tree trunk during the sliding process, so that the resultant force on the tree trunk in the circumferential direction is zero, so that the device can automatically lock on the surface of the tree trunk.

[0041] Furthermore, the auxiliary clamping arm assembly 3 also includes a movable splint 305, which is slidably arranged at the end of the auxiliary clamping arm 301 along the second direction y, and the movable splint 305 and the auxiliary clamping arm 301 are elastically connected. When the auxiliary clamping arm 301 slides toward one side of the trunk, the movable splint 305 at the end of the auxiliary clamping arm 301 preferentially contacts the surface of the trunk, and under the action of pressure, the spring mounted on one side of the movable splint 305 continuously stores energy, so that the movable splint 305 is tightly pressed against the surface of the trunk, thereby increasing the friction force to prevent the device from loosening during the injection process.

[0042] Furthermore, the auxiliary clamp arm 301 is arranged to be inclined relative to the clamping shell 204 in the xoy plane, and the auxiliary clamp arm 301 is offset from the clamping shell 204 in the third direction z, so that the auxiliary clamp arm 301 is obliquely pressed against the surface side of the trunk, so that the two groups of auxiliary clamp arms 301 do not interfere with each other during movement. At the same time, the auxiliary clamp arm 301 and the clamping shell 204 are offset in the third direction z, so that the clamping shell 204 and the movable clamp plate 305 do not interfere with each other when they abut against the surface of the trunk.

[0043] See also Figure 7 In a preferred embodiment of the present invention, the injection assembly 4 further includes an injection hole 405, and a plurality of the injection holes 405 are arranged on one side of the end of the drill bit 404 for outputting the medicine to be injected.

[0044] In actual application of this embodiment, the surface of the drill bit 404 is further provided with a plurality of injection holes 405, and the injection holes 405 are arranged in sections on the surface of the drill bit 404 along the second direction y, and the interior of the drill bit 404 adopts a hollow structure, one end of the injection cavity is connected to the plurality of injection holes 405, and the other end of the cavity can be connected to a rotating sealing ring and connected to a pump flow pipe of the liquid medicine, so that the liquid medicine can pass through the cavity along the plurality of injection holes 405 and be injected into the tree trunk, and the plurality of injection holes 405 arranged on the drill bit 404 can inject the systemic liquid medicine into the xylem and phloem of the tree trunk in sections, the liquid medicine injected into the xylem is transmitted to the stem and leaves through its own ducts, and the liquid medicine injected into the phloem can be transported to the roots through the sieve tubes, thereby preventing and controlling pests.

[0045] See also Figure 6 In a preferred embodiment of the present invention, the injection assembly 4 also includes a drill driver 406 and a drill rod collar 407. The drill driver 406 is fixedly assembled at one end of the injection shell box 401 and slidably assembled at one side of the tank shell 101. The movable shaft of the drill driver 406 is connected to the drill rod collar 407 through a synchronous belt. The drill rod collar 407 is rotatably assembled between the two sets of drill base plates 403 and fixedly connected to the drill bit 404.

[0046] In actual application of this embodiment, the drill driver 406 is fixedly arranged at one end of the injection shell box 401 and slidably assembled on one side of the trough shell body 101. When the injection shell box 401 moves along the second direction y, the drill driver 406 moves synchronously with the injection shell box 401. When the device is in a non-locked state, the drill driver 406 is in a closed state. When the device enters a locked state, the drill driver 406 switches to an open state and drives the drill rod collar 407 to rotate through a synchronous belt, so that the drill rod collar 407 synchronously drives the drill bit 404 to rotate.

[0047] Furthermore, the open state and locked state of the device can be determined by a contact switch. By setting a contact switch at both ends of the side guide groove 103, it is possible to detect the current working state of the device and use the on and off state of the contact switch as an on and off signal of the control circuit.

[0048] See also Figure 5 In a preferred embodiment of the present invention, the injection assembly 4 also includes an axis support 408, a hydraulic pump 409 and a front push frame 410. The axis support 408 is fixedly arranged at one end of the injection shell box 401. The hydraulic pump 409 is arranged in the axis support 408. The front push frame 410 is assembled on the movable shaft of the hydraulic pump 409. The front push frame 410 is fixedly connected to the drill base plate 403.

[0049] In actual application of this embodiment, the shaft bracket 408 is fixedly arranged at one end of the injection shell box 401, the hydraulic pump 409 is fixedly assembled in the shaft bracket 408, and the movable shaft at one end of the hydraulic pump 409 is fixedly connected to the drill bit base plate 403 through the front push frame 410. Therefore, when the device is switched from the open state to the locked state, the hydraulic pump 409 starts to start under the drive of the control circuit, and uses the movable shaft to push the front push frame 410 to move along the second direction y, so that the drill bit base plate 403 moves synchronously along the second direction y, and at this time, the drill bit driver 406 is started synchronously, thereby driving the drill rod collar 407 and the drill bit 404 to rotate, thereby realizing drilling on the surface of the tree trunk.

[0050] See also Figure 6 In a preferred embodiment of the present invention, the perforating and injecting device for forestry pest control also includes an adjusting mechanism 5, which includes an adjusting rod 501, a first adjusting wheel 502, an adjusting tooth plate 503, a second adjusting wheel 504 and a linkage arm 505. The adjusting rod 501 is fixedly axially arranged on one side of the sliding base 201, and the first adjusting wheel 502 and the second adjusting wheel 504 are coaxially fixedly assembled on the adjusting rod 501. One end of the adjusting tooth plate 503 is slidably assembled on the sliding base 201, and the other end of the adjusting tooth plate 503 is meshed and connected with the first adjusting wheel 502. The second adjusting wheel 504 is transmission-connected with the third transmission wheel 210. One end of the linkage arm 505 is rotationally connected with the adjusting tooth plate 503, and the other end of the adjusting tooth plate 503 is movably connected with the injection shell box 401.

[0051] When the present embodiment is actually applied, the adjusting rod 501 is fixedly mounted on one side of the sliding base 201, and the adjusting rod 501 is coaxially fixedly mounted with a first adjusting wheel 502 and a second adjusting wheel 504. Since the second adjusting wheel 504 and the third transmission wheel 210 are connected in transmission, when the clamping shell 204 slides relative to the clamping arm 202, the side tooth plate 206 on one side of the clamping shell 204 can synchronously drive the transmission shaft 208 and the third transmission wheel 210 to rotate when meshing and driving the first transmission gear 207 to rotate, and further drive the second adjusting wheel 504 and the adjusting rod 501 to rotate. The adjusting rod 501 can drive the first adjusting wheel 502 to rotate in the driving state, and the first adjusting wheel 502 is meshed and connected with the adjusting tooth plate 503, and can then mesh and drive the adjusting tooth plate 503 to reciprocate in the first direction x. When the device is switched from the open state to the locked state, the clamping shell 204 is relative to the clamping arm The sliding distance of 202 is linearly related to the number of rotations of the first transmission gear 207, and further, is linearly related to the sliding distance of the adjusting tooth plate 503.
