Description

Technical Field

[0001] The utility model relates to the technical field of electric drills, in particular to an electric drill for injection drilling of forest trees. Background Art

[0002] Drilling and injecting medicine is a short-time, fast-acting, long-term and stable method of preventing and controlling pine wood nematode disease. It involves drilling holes at the base of the trunk to allow the medicine to enter the tree, and relying on the tree's own transpiration to transport the medicine to various parts of the tree.

[0003] At present, when drilling holes for tree injection, an electric drill is generally used to drill holes in the tree trunk first, and then the injection mechanism carried by the electric drill is used for injection. However, when drilling holes, the existing electric drill will produce wood chips, and when the drill bit is removed from the hole, some wood chips will remain in the hole. In this way, during the subsequent injection, the wood chips will hinder the flow of the liquid medicine, resulting in poor use effect. In addition, since the existing electric drill has no positioning mechanism, the drilling direction of the drill bit will be offset during drilling, resulting in the drilling depth not reaching the preset value, which in turn affects the therapeutic effect of the liquid medicine. To this end, we propose an electric drill for tree injection drilling. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-Figure 5 , a forest injection drilling electric drill, comprising a second shell 12, a handle 2 is installed at one end of the bottom of the second shell 12, a battery 1 is installed at the bottom of the handle 2, a first shell 4 is arranged inside the second shell 12, one end of the first shell 4 is connected to a drill bit 5 through a chuck 25, and the other end of the chuck 25 is connected to a second motor 13, the second motor 13 is fixed inside the first shell 4, the second motor 13 is connected to a first switch 34 and the battery 1 through a wire, and the battery 1 can provide power to the second motor 13, so that during the drilling process, the staff holds the handle 2 and then applies force toward the tree trunk, and at the same time controls the second motor 13 through the first switch 34 to drive the drill bit 5 to rotate, and the drill bit 5 can drill holes at a preset position on the tree trunk, which is convenient for subsequent injection of medicine or fertilizer;

[0027] It should be noted that the surface of the drill bit 5 is provided with a spiral groove, so that during the drilling process, some debris will be discharged from the drill hole along the spiral groove;

[0028] like Figure 3 or Figure 5As shown, an injection mechanism is provided at the bottom of the second housing 12, and the injection mechanism includes a liquid medicine tank 26 fixed on the grip 2, a delivery pump 27 is installed on one side of the liquid medicine tank 26 through a mounting seat 37, the delivery pump 27 is connected to the third switch 36 and the battery 1 through a wire, and the third switch 36 is installed on the mounting seat 37, the liquid inlet of the delivery pump 27 is connected to the liquid medicine tank 26 through a pipeline, and the liquid outlet of the delivery pump 27 is connected to the injection needle 29 through an infusion tube 28, and the injection needle 29 is located in a storage tube 31, and the storage tube 31 is fixed to the bottom of the second housing 12, and the storage tube 31 is fixed to the bottom of the second housing 12. A through slot 33 is provided at the bottom of the receiving tube 31, and a paddle 30 is installed at one end of the bottom of the injection needle 29, and the bottom of the paddle 30 extends below the through slot 33. After the drilling is completed, the staff removes the drill bit 5, and then removes the rubber plug 32 from the end of the receiving tube 31, and then pushes the paddle 30 to extend one end of the injection needle 29 from the receiving tube 31, so that the end of the injection needle 29 extends to the inside of the drilled hole in the tree trunk, and then controls the delivery pump 27 to work, and delivers the liquid medicine in the liquid medicine tank 26 to the injection needle 29 through the infusion tube 28, and finally injects it into the drilled hole.

[0029] It should be noted that the rubber plug 32 can be connected to the storage tube 31 via a connecting rope, which can prevent the rubber plug 32 from being lost.

[0030] like Figure 3 As shown, a rotating shaft 16 is rotatably connected to one end of the second housing 12, the top of the rotating shaft 16 passes through the second housing 12 and is connected to the first motor 11, the first motor 11 is fixed on the second housing 12, the end of the rotating shaft 16 is connected to the cam 15, a push rod 20 is installed at the end of the first housing 4, the push rod 20 is connected to the cam 15 through the ball 21, the first motor 11 is connected to the battery 1 through the second switch 35 of the wire, and the battery 1 can provide electric energy to the first motor 11, so that the first motor 11 drives the cam 15 to rotate, and then drives the push rod 20 to move, so that the drill bit 5 can reciprocate linearly after the drilling is completed, and the debris remaining in the hole is taken out through the spiral groove on the surface of the drill bit 5, and the inner wall of the hole is made smooth;

[0031] like Figure 2 As shown, a first limiting ring 17 is installed on the inner wall of the second housing 12, and a second limiting ring 19 is installed on the outer surface of the first housing 4. The second limiting ring 19 is connected to the first limiting ring 17 through a spring 18, and the adjacent surfaces of the first limiting ring 17 and the second limiting ring 19 are both against the end of the spring 18. Under the action of the spring 18, the ball 21 at the end of the push rod 20 can be in close contact with the cam 15, so that the rotation of the cam 15 can drive the drill bit 5 to perform linear reciprocating motion;

[0032] It should be noted that in order to prevent the rotating shaft 16 and the cam 15 from being subjected to excessive force during the drilling process, a threaded through hole 24 is opened on one side of the second shell 12, and a locking bolt 3 is rotatably connected inside the threaded through hole 24, and one end of the locking bolt 3 is in contact with the side of the first shell 4. During the drilling process, by tightening the locking bolt 3, under the action of the threaded through hole 24, one end of the locking bolt 3 is tightly pressed against the side of the first shell 4, thereby fixing the first shell 4. In this way, during the drilling process, the force applied to the first shell 4 will not be transmitted to the rotating shaft 16 and the cam 15.

[0033] like Figure 1 As shown, a guide rail 10 is installed on one side of the top of the second housing 12, a slider 9 is slidably connected to the guide rail 10, a connecting rod 8 is rotatably connected to the top of the slider 9, a connecting block 7 is rotatably connected to the end of the connecting rod 8, and a positioning plate 6 is installed on the other side of the connecting block 7. The positioning plate 6 is set to a "V" shape structure, so that when drilling, the positioning plate 6 can be against the tree trunk, such as Figure 4 As shown, the drilling direction of the drill bit 5 will be toward the tree core, preventing the drilling direction from deflecting and improving the stability of the drilling during drilling.

[0034] Specifically, when the utility model is in use, the staff installs the slider 9 on the guide rail 10, then puts the positioning plate 6 against the tree trunk, and holds the positioning plate 6 with one hand, so that the drill bit 5 is aligned with the core of the tree trunk, and the angle between the drill bit 5 and the tree trunk is maintained at a preset value, and then the staff holds the handle 2, and controls the second motor 13 to work through the first switch 34, and the second motor 13 drives the drill bit 5 to rotate, and the staff applies a force toward the trunk direction to the handle 2, and the drill bit 5 drills a hole in the trunk, and at the same time, the slider 9 moves along the guide rail 10, so that the drill bit 5 remains stable during drilling, and when the drilling is completed, the staff rotates the locking bolt 3, so that the end of the locking bolt 3 is separated from the outer wall of the first housing 4 under the action of the threaded through hole 24, and then pulls the drill bit 5 out of the drill hole, and while pulling out the drill bit 5, the staff controls the first motor 11 to work through the second switch 35, The first motor 11 drives the cam 15 to rotate. Under the action of the spring 18, the ball 21 at the end of the push rod 20 is in tight contact with the side of the cam 15, so that the drill bit 5 performs reciprocating linear motion during the rotation of the cam 15, so that the drill bit 5 can polish the inner wall of the borehole smooth and also take out the debris generated by the borehole. When the drill bit 5 is removed from the borehole, the staff turns off the first motor 11 and the second motor 13, and removes the drill bit 5, and then pulls the rubber plug 32 out of the storage tube 31, and then the staff pushes the paddle 30 to move one end of the injection needle 29 out of the storage tube 31, and the staff inserts the end of the injection needle 29 into the borehole, and then controls the delivery pump 27 to work through the third switch 36, and the delivery pump 27 delivers the liquid medicine in the liquid medicine tank 26 to the injection needle 29 through the infusion tube 28, and injects it into the borehole along the injection needle 29 to complete the injection.

[0035] Furthermore, Figure 3 As shown, a plurality of limit blocks 23 are equidistantly installed on one end of the inner surface of the second shell 12, and a plurality of limit grooves 22 are correspondingly opened on the outer surface of the first shell 4. One end of each limit block 23 extends into the corresponding limit groove 22. With the cooperation of the limit groove 22 and the limit block 23, the first shell 4 and the second shell 12 can be limited to prevent the first shell 4 from rotating relative to the second shell 12 when drilling.

[0036] Furthermore, Figure 2 As shown, a stopper 14 is installed at one end of the guide rail 10 away from the drill bit 5, and the edges of the stopper 14 extend to the outside of the guide rail 10. The stopper 14 can limit the slider 9 to prevent the slider 9 from falling off the guide rail 10 when drilling.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
