In the agricultural disease and pest prevention and control, a tree trunk punching and medicine injecting method is often used. Compared with other prevention and control methods, the tree trunk punching and medicine injecting method can precisely and efficiently deliver medicine to each part (branches and leaves, roots) of a tree body, especially to a hiding place of a pest that is difficult to contact through external spraying, and avoids waste of medicine. In the tree trunk punching and medicine injecting process, medicine liquid is prepared first, a punching point is selected, punching is performed, and then the medicine is injected into the tree trunk.

[0013] The beneficial effects of the present application are:

[0014] 1. First, when the punching and medicine injection operation is needed, the device is moved to the appropriate punching position, the motor is started, and the punching operation is started. After the punching operation is completed, the medicine injection operation can be automatically performed without moving the threaded drill bit. The whole operation is automatic, and the work efficiency is high.

[0015] 2. Secondly, when the medicine injection operation is performed, the liquid medicine is sprayed in the tree trunk through the rotating injection hole, and is not limited to one place. The damage of the injected liquid medicine to the inside of the tree trunk is small. Under the blocking action of the rhombic plate, the injection direction of the liquid medicine changes, and the liquid medicine is not directly sprayed to the tree trunk. This not only reduces the possibility of damage caused by direct injection of the liquid medicine to the tree trunk, but also makes the liquid medicine spray more uniform.

[0016] 3. At the same time, when the position of the rhombic plate relative to the injection hole changes during the medicine injection operation, the injection angle of the liquid medicine also changes, which can make the liquid medicine more uniformly sprayed in the tree trunk and improve the medicine injection effect.

[0017] 4. Furthermore, when the distance between the rhombic plate and the injection hole changes during the medicine injection operation, the speed of the liquid medicine flowing out of the injection hole will be affected, preventing the impact force of the liquid medicine from being too large due to the excessive flow rate, which can cause irreversible damage to the tree trunk.

[0018] 5. Finally, during the rotation of the rotating circular rod, the moving frame moves back and forth relative to the injection hole under the action of the annular groove and the sliding rod, which further changes the injection direction of the liquid medicine from both sides of the rhombic plate, so that the liquid medicine can be sprayed in most of the space of the tree trunk, improving the uniformity of the liquid medicine spray.

DETAILED DESCRIPTION

[0032] Reference is made to Figures 1-12The utility model provides a kind of insect disease prevention and control tree trunk punching medicine injection tool, including body 1 and fixed block 2, fixed block 2 rotationally penetrates and is connected with fixed tube 4, one end of fixed tube 4 is rotationally connected with transmission hose 3, transmission hose 3 and body 1 are rotationally connected, and multiple medicine injection holes 37 are opened on the outer side wall of fixed tube 4, and body 1 includes shell, water tank is fixedly connected in shell, water pump is fixedly connected on the outer side of water tank, water pump and transmission hose 3 are fixedly connected, before punching medicine injection operation is carried out, appropriate amount of liquid medicine is added to water tank first, when needing to carry out medicine injection operation, start water pump, and water pump will make the liquid medicine in water tank discharge along the mode of water tank-transmission hose 3-fixed tube 4-medicine injection hole 37, and then flow into tree trunk, finally complete medicine injection operation;

[0033] The outer side of the fixed block 2 is provided with a clamping assembly, and the clamping assembly comprises fixed frames 8 fixedly installed on both sides of the fixed block 2.

[0034] Before punching medicine injection operation is carried out, the punching medicine injection position is determined first, the fixed block 2 is manually lifted, the fixed block 2 is placed in front of the punching medicine injection position, and the hydraulic clamping jaw 6 is started to make the hydraulic clamping jaw 6 abut against the tree trunk, so as to complete the limiting operation of the position of the fixed block 2.

[0035] One end of the fixed tube 4 is rotationally connected with a fixed rod 9, the outer side of the fixed rod 9 is fixedly connected with a threaded drill bit 5, the outer side of the fixed block 2 is fixedly connected with a motor 15, the output end of the motor 15 is fixedly connected with a first gear 16, the outer side of the fixed tube 4 is fixedly connected with a second gear 17, and the first gear 16 and the second gear 17 are engaged.

[0036] When punching medicine injection operation is needed, the motor 15 is started first, the motor 15 drives the fixed tube 4 to rotate through the first gear 16 and the second gear 17, the fixed tube 4 drives the threaded drill bit 5 to rotate through the fixed rod 9 (the structure and principle that the fixed rod 9 can drive the threaded drill bit 5 to rotate are described below), the threaded drill bit 5 drills into the tree trunk, and the drilling operation starts, after drilling is completed, the body 1 is started, and the medicine injection operation starts.

[0037] The outer side of the fixed pipe 4 is provided with a control assembly, which comprises a threaded cylinder 14 sleeved on the outer side of the fixed pipe 4, a control plate 7 threadedly connected to the outer side of the threaded cylinder 14, a rotating circular rod 24 rotatably connected to the threaded cylinder 14, a protective circular ring 13 rotatably connected to the outer side of the rotating circular rod 24, the protective circular ring 13 being located on the outer side of the medicine injection hole 37 and opposite to the medicine injection hole 37, an arc-shaped groove 32 being formed in the threaded cylinder 14, a fixed plate 23 fixedly connected to the outer side of the fixed pipe 4, annular extension rods 33 fixedly connected to the both sides of the fixed plate 23, a sliding plate 35 fixedly connected to the side of the annular extension rods 33 away from the fixed plate 23, the sliding plate 35 being slidably connected to the inner wall of the arc-shaped groove 32, a first spring 34 fixedly connected between the sliding plate 35 and the fixed plate 23, a moving frame 40 slidably mounted on the outer side of the protective circular ring 13, a rhombic plate 41 fixedly connected in the moving frame 40, a differential assembly for controlling the movement of the threaded cylinder 14 relative to the fixed pipe 4 being mounted on the outer side of the fixed block 2, a rotating circular plate 12 rotatably connected to the outer side of the rotating circular rod 24, a second spring 36 fixedly connected between the rotating circular plate 12 and the fixed pipe 4, two recesses 11 being symmetrically formed in the inner side of the rotating circular plate 12, and protrusions 10 slidably connected in the two recesses 11, the protrusions 10 being fixedly connected with the fixed rod 9.

[0038] Before the punching and medicine injection operation is performed, the actual drilling depth of the threaded drill bit 5 is selected according to the actual situation of the tree trunk, the control plate 7 is rotated, the position of the control plate 7 on the threaded cylinder 14 is adjusted, and the threaded drill bit 5 is fixed on the fixed pipe 4. Figure 2For example, the distance between the control plate 7 and the end of the threaded drill bit 5 is the actual drilling depth. In the initial state, the protrusion 10 is located in the groove 11. When the fixed tube 4 starts to rotate, the fixed tube 4 drives the fixed plate 23 to rotate. The fixed plate 23 drives the threaded cylinder 14 to rotate through the first spring 34. The threaded cylinder 14 drives the rotating circular plate 12 to rotate through the rotating circular rod 24 and the fixed circular rod 28. The rotating circular plate 12 drives the fixed rod 9 to rotate through the groove 11 and the protrusion 10. The fixed rod 9 drives the threaded drill bit 5 to rotate. The threaded drill bit 5 enters the trunk. At this time, under the resistance of the trunk, the first spring 34 is deformed until the fixed plate 23 abuts against the inner wall of the arc-shaped groove 32. At this time, the fixed plate 23 abuts against the inner wall of the arc-shaped groove 32, which also drives the threaded cylinder 14 to rotate until the trunk abuts against the control plate 7. At this time, under the resistance of the trunk, the control plate 7 moves to the right relative to the fixed tube 4 in the drilling direction to the left. The control plate 7 drives the threaded cylinder 14 to move to the right. Since the rotating circular rod 24 is rotationally connected with the threaded cylinder 14, the rotating circular plate 12, and the protective circular ring 13, the threaded cylinder 14 moving to the right drives the protective circular ring 13 and the rotating circular plate 12 to move to the right as a whole through the rotating circular rod 24, so that the protrusion 10 moves out of the groove 11. At this time, the rotating rotating circular plate 12 does not drive the threaded drill bit 5 to move, and the threaded drill bit 5 stops rotating. In the initial state, the protective circular ring 13 is located outside the medicine injection hole 37. When the threaded cylinder 14 moves relative to the fixed tube 4, the protective circular ring 13 moves with the rotating circular rod 24, so that the medicine injection hole 37 is opened. The moving frame 40 and the rhombus plate 41 move to the outside of the medicine injection hole 37. At this time, the body 1 is started, and the medicine injection operation is started. The medicine liquid is sprayed in the trunk through the medicine injection hole 37. After the medicine injection is completed, the threaded drill bit 5 is pulled out, and the punching and medicine injection operation is finally completed.

[0039] It should be noted that the diameter of the right end of the threaded drill bit 5 is greater than the diameter of the rotating circular plate 12, the protective circular ring 13, and the threaded cylinder 14. That is, during the drilling process, the rotating circular plate 12, the protective circular ring 13, and the threaded cylinder 14 do not abut against the trunk, and do not hinder the drilling work.

[0040] The differential assembly comprises a mounting plate 18 fixedly mounted on the side wall of the fixed block 2, a rotating shaft 30 rotatably connected to the side wall of the mounting plate 18, a third gear 20 fixedly connected to the outer side of the rotating shaft 30, a fourth gear 27 fixedly connected to the outer side of the fixed tube 4, the third gear 20 and the fourth gear 27 being engaged with each other, a control circular plate 21 fixedly connected to the outer side of the rotating shaft 30, a connecting plate 22 rotatably connected to the outer side of the control circular plate 21 through a mounting rod, the mounting rod and the control circular plate 21 being eccentrically arranged, the outer side of the connecting plate 22 being rotatably connected to an extrusion plate 29, the extrusion plate 29 being slidably connected to the mounting plate 18 through a limiting rod 19, and a plurality of fixed circular rods 28 fixedly penetrating through the threaded cylinder 14, the plurality of fixed circular rods 28 being fixedly connected to the protective circular ring 13 and the rotating circular plate 12;

[0041] When the punching operation is performed, the moving extrusion plate 29 will not abut against the fixed circular rod 28 or the rotating circular rod 24, and when the medicine injection operation is performed, the moving extrusion plate 29 will abut against the fixed circular rod 28 or the rotating circular rod 24. In addition, when the medicine injection operation is performed, the motor 15 is always in an open state, so that the fixed tube 4 is always in a rotating state, that is, the liquid medicine is sprayed in the tree trunk in a rotating manner through the medicine injection hole 37, and is not limited to a certain position. The damage of the injected liquid medicine to the inside of the tree trunk is small. In this process, the rotating fixed tube 4 drives the rotating shaft 30 to rotate through the third gear 20 and the fourth gear 27. Since the diameter of the third gear 20 is smaller than that of the fourth gear 27, the rotating speed of the third gear 20 is greater than that of the fourth gear 27. The rotating shaft 30 drives the control circular plate 21 to rotate. Since the mounting rod at the end of the control circular plate 21 and the connecting plate 22 is eccentrically arranged, the rotating rotating circular rod 24 drives the extrusion plate 29 to move back and forth through the connecting plate 22. In this process, there are two different situations, as shown in Figure 12 Fig. 1. The first situation (i.e. the situation on the left side in Figure 12 Fig. 1): when the extrusion plate 29 moves to the right, one of the rotating circular rod 24 or the fixed circular rod 28 is located on the right side of the extrusion plate 29, and the distance between the extrusion plate 29 and the rotating circular rod 24 or the fixed circular rod 28 is small. Since the moving speed of the extrusion plate 29 is fast, the extrusion plate 29 will abut against the rotating circular rod 24 or the fixed circular rod 28, so that the rotating circular rod 24 or the fixed circular rod 28 drives the threaded cylinder 14 to rotate relative to the fixed tube 4 until the extrusion plate 29 and the rotating circular rod 24 or the fixed circular rod 28 are disconnected. At this time, the threaded cylinder 14 returns to the original position relative to the fixed tube 4,

[0042] The second situation (i.e. the situation on the right side in Figure 12The right side of the case): when the extrusion plate 29 moves to the right, one of the rotating round rod 24 or the fixed round rod 28 is located at the lower right side of the extrusion plate 29, and the spacing between the rotating round rod 24 or the fixed round rod 28 and the extrusion plate 29 is small. During the rotation of the rotating round rod 24 and the fixed round rod 28 following the threaded barrel 14, when the rotating round rod 24 or the fixed round rod 28 abuts against the extrusion plate 29, the extrusion plate 29 will form an obstacle to the rotating round rod 24 or the fixed round rod 28, that is, the extrusion plate 29 will hinder the threaded barrel 14 from rotating following the fixed tube 4 until the extrusion plate 29 and the rotating round rod 24 or the fixed round rod 28 are disconnected. In the above two cases, the threaded barrel 14 will be deflected relative to the fixed tube 4, but the deflection directions are different, and when the deflection occurs, the position of the diamond plate 41 relative to the medicine injection hole 37 will be deflected. Due to the special shape of the diamond plate 41, as shown in Figure 10 It can be seen that when the liquid medicine is sprayed into the tree trunk through the medicine injection hole 37, the injection direction of the liquid medicine will change under the obstruction of the diamond plate 41. The liquid medicine is not directly sprayed into the tree trunk, which not only can reduce the possibility of damage to the tree trunk caused by direct injection of the liquid medicine, but also can make the liquid medicine spray more uniformly. When the position of the diamond plate 41 relative to the medicine injection hole 37 changes, the injection angle of the liquid medicine will also change, which can make the liquid medicine spray more uniformly in the tree trunk and improve the medicine injection effect.

[0043] The offset assembly is installed outside the fixed tube 4, the offset assembly comprises a fifth gear 25 slidably installed outside the rotating round rod 24, the fixed tube 4 is fixedly connected with a sixth gear 26 outside, the rotating round rod 24 is further fixedly connected with a cam 38 outside, the side wall of the protective circular ring 13 is slidably connected with a moving rod 39, the moving rod 39 and the protective circular ring 13 are fixedly connected with a third spring 43, the moving rod 39 slidably penetrates through a moving frame 40, two annular grooves 31 are formed in the outer side of the rotating round rod 24, the upper side of the moving frame 40 is fixedly connected with two slide rods 42, one end of each of the two slide rods 42 extends into the annular groove 31 and is slidably connected with the annular groove 31;

[0044] First, the fifth gear 25 and the sixth gear 26 are always in meshing state, when the rotating round rod 24 and the threaded cylinder 14 as a whole relative to the fixed tube 4 occurs rotation, because the sixth gear 26 and the fifth gear 25 are always in meshing state, thus will cause the fifth gear 25 rotation, the fifth gear 25 drives the rotating round rod 24 to rotate, the rotating round rod 24 drives the cam 38 to rotate, under the action of the third spring 43, the moving rod 39 is always and the cam 38 resistance, thus the rotating cam 38 will drive the moving rod 39 and the moving frame 40 up and down, the moving frame 40 drives the diamond plate 41 up and down, the diamond plate 41 and the injection hole 37 between the interval changes, because the diamond plate 41 and the injection hole 37 between the interval is small, thus the moving diamond plate 41 will affect the speed of the liquid medicine from the injection hole 37 out, prevent the liquid medicine flow rate too fast to the impact force of the tree trunk is too large, cause irreversible damage to the tree trunk, at the same time, in the rotating round rod 24 rotates in the process, under the action of the annular groove 31 and the slide rod 42, will cause the moving frame 40 relative to the injection hole 37 transverse back and forth movement, cause the liquid medicine from the diamond plate 41 both sides of the injection direction further change, can make the liquid medicine is sprayed in the tree trunk of most space, improve the uniformity of liquid medicine spraying.

[0045] In the application, before the punching and medicine injection operation is performed, the actual drilling depth of the threaded drill bit 5 is selected according to the actual situation of the tree trunk, the position of the control plate 7 on the threaded cylinder 14 is adjusted, the motor 15 is started first, the motor 15 drives the fixed pipe 4 to rotate through the first gear 16 and the second gear 17, the fixed pipe 4 drives the threaded cylinder 14 to rotate through the fixed plate 23 and the first spring 34, the threaded cylinder 14 drives the rotating circular plate 12 to rotate through the rotating circular rod 24 and the fixed circular rod 28, the rotating circular plate 12 drives the fixed rod 9 to rotate through the groove 11 and the protrusion 10, the fixed rod 9 drives the threaded drill bit 5 to rotate, the threaded drill bit 5 enters the tree trunk, at this time, under the resistance of the tree trunk, the first spring 34 is deformed until the fixed plate 23 abuts against the inner wall of the arc-shaped groove 32, at this time, the fixed plate 23 abuts against the inner wall of the arc-shaped groove 32, and the threaded cylinder 14 is also driven to rotate until the tree trunk abuts against the control plate 7, at this time, under the resistance of the tree trunk, the control plate 7 moves to the right relative to the fixed pipe 4, the control plate 7 drives the threaded cylinder 14 to move to the right, the threaded cylinder 14 drives the protective circular ring 13 and the rotating circular plate 12 as a whole to move to the right through the rotating circular rod 24, so that the protrusion 10 moves out of the groove 11, at this time, the rotating rotating circular plate 12 does not drive the threaded drill bit 5 to move, and the threaded drill bit 5 stops rotating, when the threaded cylinder 14 moves relative to the fixed pipe 4, the protective circular ring 13 moves with the rotating circular rod 24, so that the medicine injection hole 37 is opened, the moving frame 40 and the diamond plate 41 move to the outside of the medicine injection hole 37, at this time, the body 1 is started, and the medicine injection operation is started, the liquid medicine is sprayed into the tree trunk through the medicine injection hole 37, after the liquid medicine injection is completed, the threaded drill bit 5 is pulled out, and the punching and medicine injection operation is finally completed.

[0046] When the punching operation is performed, the fixed pipe 4 is always in a rotating state, that is, the liquid medicine is sprayed into the tree trunk in a rotating manner through the medicine injection hole 37, and the rotating fixed pipe 4 drives the rotating shaft 30 to rotate through the third gear 20 and the fourth gear 27, and the rotating speed of the third gear 20 is greater than that of the fourth gear 27, the rotating shaft 30 drives the control circular plate 21 to rotate, the rotating circular rod 24 drives the extrusion plate 29 to move back and forth through the connecting plate 22, in this process, the threaded cylinder 14 is deflected relative to the fixed pipe 4, and the diamond plate 41 is deflected relative to the position of the medicine injection hole 37, when the liquid medicine is sprayed into the tree trunk through the medicine injection hole 37, under the resistance of the diamond plate 41, the liquid medicine injection direction is changed, the liquid medicine is not directly sprayed to the tree trunk, which not only can reduce the possibility of damage to the tree trunk caused by direct injection of the liquid medicine, but also can make the liquid medicine spray more uniform, and when the position of the diamond plate 41 relative to the medicine injection hole 37 changes, the injection angle of the liquid medicine also changes, which can make the liquid medicine spray more uniformly in the tree trunk, and improve the medicine injection effect.

[0047] When the rotating round rod 24 and the threaded cylinder 14 rotate as a whole relative to the fixed tube 4, under the action of the sixth gear 26 and the fifth gear 25, the fifth gear 25 drives the rotating round rod 24 and the cam 38 to rotate, under the action of the third spring 43, the moving rod 39 is always in contact with the cam 38, so the rotating cam 38 drives the moving rod 39 and the moving frame 40 to move up and down, the moving frame 40 drives the diamond plate 41 to move up and down, the distance between the diamond plate 41 and the medicine injection hole 37 changes, because the distance between the diamond plate 41 and the medicine injection hole 37 is small, so the moving diamond plate 41 can affect the speed of the medicine flowing out of the medicine injection hole 37, prevent the impact force of the medicine flowing too fast on the tree trunk, prevent the irreversible damage to the tree trunk, at the same time, in the process of rotating the rotating round rod 24, under the action of the annular groove 31 and the sliding rod 42, the moving frame 40 moves back and forth transversely relative to the medicine injection hole 37, so that the spraying direction of the medicine from the two sides of the diamond plate 41 changes further, so that the medicine can be sprayed in most of the space of the tree trunk, improve the uniformity of the medicine spraying.
