Description

Technical Field

[0001] This utility model relates to the field of tree maintenance technology, and in particular to a tree rejuvenation device. Background Technology

[0002] Rejuvenation is the process of restoring or essentially restoring the original robustness and productivity of a variety that has already degenerated or begun to degenerate. For example, if a seedling is infested with a large number of pests, causing it to become weak and emaciated, then rejuvenation is necessary. Currently, a common rejuvenation method is to use a syringe to inject a treatment solution into the seedling to drive away the pests and achieve the rejuvenation effect.

[0003] The current method of injecting seedlings for rejuvenation mostly involves staff using a syringe to draw the liquid and insert it into a micro-hole to complete the injection. Because the syringe is small, after each injection, the syringe needs to be pulled out, the liquid drawn out, and then inserted back into the micro-hole on the trunk for injection, which reduces the injection efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tree rejuvenation device.

An injection needle is fixedly connected to the left side of the injection cylinder, a liquid supply assembly is fixedly connected to the lower surface of the injection cylinder, stabilizing assemblies are fixedly connected to the front and back of the injection cylinder, and an injection assembly is fixedly connected to the inner bottom wall of the injection cylinder. The injection assembly includes a fixing plate with an inlet and an outlet hole on its side. A piston is slidably connected to the inner wall of the injection cylinder, a push rod is fixedly connected to the right side of the piston, a circular hole is formed on the side of the piston, a sleeve is slidably connected to the inner wall of the circular hole, the right end of the sleeve is fixedly connected to the right inner wall of the injection cylinder, through holes are formed on both sides of the sleeve, a circular rod is slidably connected to the inner wall of the through hole, a limit block is fixedly connected to the surface of the circular rod, a first spring is sleeved on the surface of the circular rod, and a baffle is fixedly connected to the left end of the circular rod.

[0007] Preferably, the left end of the first spring overlaps with the right side of the limiting block, the right end of the first spring overlaps with the right inner wall of the sleeve, and the position of the circular rod corresponds to the position of the liquid outlet, and the size of the baffle is larger than the size of the liquid outlet.

[0008] Preferably, a strip frame is fixedly connected to the right inner wall of the syringe, and a strip hole adapted to the strip frame is opened on the side of the piston. A through hole is opened on both the left and right sides of the strip frame. A push rod is slidably connected to the inner wall of the through hole. The right end of the push rod extends to the right side of the syringe, and a squeezing plate is fixedly connected to the left end of the push rod. A second spring is sleeved on the surface of the push rod, and a bent tube is fixedly connected to the left side of the fixed plate at a position corresponding to the liquid inlet.

[0009] Preferably, the position of the extrusion plate corresponds to the position of the liquid inlet, and the size of the extrusion plate is larger than the size of the liquid inlet. The left end of the second spring overlaps with the right side of the extrusion plate, and the right end of the second spring overlaps with the left side of the strip frame.

[0012] The beneficial effects of this utility model are as follows:

[0013] By designing the injection assembly, the circular rod and push rod can alternately block and expose the outlet and inlet holes during use, thereby improving the efficiency of drug extraction and injection from the syringe. During extraction, the baffle blocks the outlet hole while the squeeze plate disengages from the inlet hole, concentrating the negative pressure effect entirely at the inlet hole. During injection, the squeeze plate blocks the inlet hole while the baffle disengages from the outlet hole, allowing the drug to enter the tree entirely through the outlet hole and the injection needle. This eliminates the need for staff to repeatedly pull out and reinsert the syringe, significantly improving the injection efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0020] Reference Figure 1-4 A tree rejuvenation device includes an injection cylinder 1, an injection needle tube 2 fixedly connected to the left side of the injection cylinder 1, a liquid supply component fixedly connected to the lower surface of the injection cylinder 1, stabilizing components fixedly connected to the front and back of the injection cylinder 1, an injection component fixedly connected to the inner bottom wall of the injection cylinder 1, the injection component including a fixing plate 3, an inlet hole and an outlet hole opened on the side of the fixing plate 3, a piston 4 slidably connected to the inner wall of the injection cylinder 1, a push rod 5 fixedly connected to the right side of the piston 4, a round hole opened on the side of the piston 4, a sleeve 6 slidably connected to the inner wall of the round hole, the right end of the sleeve 6 fixedly connected to the right inner wall of the injection cylinder 1, through holes opened on both the left and right sides of the sleeve 6, a circular rod 7 slidably connected to the inner wall of the through hole, a limit block 8 fixedly connected to the surface of the circular rod 7, a first spring 9 sleeved on the surface of the circular rod 7, and a baffle 10 fixedly connected to the left end of the circular rod 7.

[0021] The left end of the first spring 9 overlaps with the right side of the limiting block 8, and the right end of the first spring 9 overlaps with the right inner wall of the sleeve 6. The position of the circular rod 7 corresponds to the position of the liquid outlet. The size of the baffle 10 is larger than the size of the liquid outlet. A strip frame 11 is fixedly connected to the right inner wall of the syringe 1. A strip hole adapted to the strip frame 11 is opened on the side of the piston 4. Round through holes are opened on both the left and right sides of the strip frame 11. A push rod 12 is slidably connected to the inner wall of the round through hole. The right end of the push rod 12 extends to the right side of the syringe 1, and a squeeze plate 13 is fixedly connected to the left end of the push rod 12. A second spring 14 is fitted on the surface of the top rod 12. A bent pipe 15 is fixedly connected to the left side of the fixing plate 3 at a position corresponding to the liquid inlet hole. The position of the squeezing plate 13 corresponds to the position of the liquid inlet hole, and the size of the squeezing plate 13 is larger than the size of the liquid inlet hole. The left end of the second spring 14 overlaps with the right side of the squeezing plate 13, and the right end of the second spring 14 overlaps with the left side of the strip frame 11. The liquid supply assembly includes a connecting pipe 16, which is connected to the bent pipe 15. A liquid supply tank 17 is fixedly connected to the bottom end of the connecting pipe 16, and an adding pipe 18 is connected to the front of the liquid supply tank 17.

[0022] When drawing the liquid from the supply tank 17, the push rod 5 is pulled to the right, causing the piston 4 to move to the right inside the syringe 1. At the same time, the operator pulls the circular rod 7 and the push rod 12 to the right. The circular rod 7 moves the baffle 10 to block the outlet and squeezes the first spring 9 through the limit block 8. Simultaneously, the push rod 12 moves the squeeze plate 13 away from the inlet and causes the second spring 14 to deform. At this time, the negative pressure suction effect generated by the piston 4 acts entirely on the inlet, and the liquid from the supply tank 17 is drawn into the syringe 1 through the bent pipe 15 and the connecting pipe 16, without passing through... The outlet hole generates negative pressure. When the liquid in the syringe 1 is full, the circular rod 7 and the top rod 12 are released. At this time, the first spring 9 generates a reaction force and drives the baffle 10 to disengage from the outlet hole. The second spring 14 generates a reaction force and drives the squeezing plate 13 to block the inlet hole. At this time, pushing the push rod 5 to the left will drive the piston 4 to squeeze the liquid in the syringe 1, so that the liquid enters the tree through the outlet hole and the injection needle tube 2, completing the liquid injection operation. There is no need for the staff to repeatedly pull the injection needle tube 2 out of the tree trunk, extract the liquid and then insert it again, which greatly improves the efficiency of liquid injection.

[0023] The stabilizing component includes positioning blocks 19. The first strap 20 and the second strap 21 are fixedly connected to the side of the two positioning blocks 19 away from the syringe 1, and the front sides of the first strap 20 and the second strap 21 are fixedly connected to the Velcro tab 22 and the Velcro tab 23, respectively.

[0024] The syringe 1 can be fixed to the tree trunk by using the first strap 20, the second strap 21, the Velcro 22 and the Velcro 23 together, freeing up the staff's arms to support the syringe 1, increasing stability and reducing the difficulty of operation.

[0025] Working principle: First, the injection needle 2 is inserted into the micro-injection hole of the tree. The injection cylinder 1 is then bound to the tree trunk using the first strap 20 and the second strap 21, and then secured with Velcro fasteners 22 and 23. After completion, the push rod 5 is pulled to the right, causing the piston 4 to move to the right. At the same time, the operator pulls the circular rod 7 and the top rod 12 to the right. The circular rod 7 can move the baffle 10 to block the liquid outlet and cause the limiting block 8 to squeeze the first spring 9. Meanwhile, the top rod 12 can move the squeezing plate 13 away from the liquid inlet and squeeze the second spring 14, so that the liquid outlet on the fixing plate 3 is blocked and the liquid inlet is exposed. At this time, the negative pressure generated by the piston 4 passes through the liquid inlet and the bent tube 15. The liquid medicine in the supply tank 17 is drawn into the syringe 1 by the connecting tube 16. After the drawing is completed, the circular rod 7 and the top rod 12 are released. At this time, the first spring 9 and the second spring 14 generate a reaction force and drive the baffle 10 to disengage from the liquid outlet. The squeezing plate 13 blocks the liquid inlet. At this time, the push rod 5 is pushed to the left, which drives the piston 4 to move to the left. The piston 4 can squeeze the liquid medicine in the syringe 1 and pass the liquid medicine through the liquid outlet and enter the tree through the injection needle tube 2. There is no need for the staff to repeatedly pull out the syringe 1 to draw and inject the liquid medicine, which greatly improves the injection efficiency. In addition, the first binding strap 20 and the second binding strap 21 can fix the syringe 1 to the tree trunk, which makes it more stable.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
