Description

Technical Field

[0001] This utility model relates to the technical field of pressurized drug injection devices, specifically a pressurized drug injection device. Background Technology

[0002] In the process of cultivating trees, in order to ensure that the trees can grow healthily and stay away from insects, pests and diseases, it is usually necessary to use a pressurized injection device to inject drugs into the inside of diseased trees so that the trees can be treated with drugs.

[0003] In existing technologies, when treating trees using pressure injection devices, the needle is usually inserted directly into the trunk, and the medication is injected into the trunk using pressure. However, in actual use, because the trunk is hard, the needle is subjected to a lot of pressure when inserted directly into the trunk. After repeated insertions, the needle is prone to bending, making it impossible to insert the needle properly into the trunk. Therefore, it is necessary to improve the pressure injection device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a pressurized drug injection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pressure injection device, including a handle one, a handle two fixedly installed on the right side of the handle one, a drilling injection mechanism provided on the top of the handle one, and pressure injection mechanisms provided both outside and inside the drilling injection mechanism.

[0006] The drilling and injection mechanism includes a drilling assembly and a pin assembly, with the pin assembly located on the right side of the drilling assembly.

[0007] Preferably, the drilling assembly includes a first mounting shell, which is fixedly mounted on the top of a first handle. A second mounting shell is fixedly mounted on the outside of the first mounting shell. A hollow shaft is rotatably mounted inside the first mounting shell. A hollow drill rod is fixedly mounted on the left side of the hollow shaft. A gear ring is fixedly mounted on the outside of the hollow shaft. A motor is fixedly mounted on the top of the first mounting shell. A gear is fixedly mounted on the left side of the motor's drive shaft, facilitating drilling into the tree trunk through the drilling assembly.

[0008] Preferably, the motor is located inside the second mounting housing, and the gear meshes with the gear ring to facilitate the normal rotation of the hollow drill rod.

[0009] Preferably, the needle insertion assembly includes an injection needle tube body, which is slidably installed inside the mounting housing. An injection needle is fixedly installed on the left side of the injection needle tube body. A sliding lug and a threaded lug are fixedly installed on the outside of the injection needle tube body. A limiting rod is slidably installed inside the sliding lug. A short-threaded extension rod is threaded inside the threaded lug. A rotation limiting block is rotatably installed outside the short-threaded extension rod. An injection hopper is provided at the top of the injection needle tube body to facilitate the insertion of the injection needle into the trunk through the needle insertion assembly.

[0010] Preferably, the injection needle is slidably installed inside the hollow drill rod, the back of the limiting rod is fixedly installed to the front of the mounting shell, and the front of the rotating limiting block is fixedly installed to the back of the mounting shell, thereby improving stability.

[0011] Preferably, the pressurized injection mechanism includes a mounting block, which is fixedly installed at the bottom of the injection needle body. A cylinder is fixedly installed on the right side of the mounting block, a connecting plate is fixedly installed on the right side of the cylinder, a push rod is fixedly installed on the left side of the connecting plate, and a piston is fixedly installed on the left side of the push rod, so as to facilitate pressurized injection of medicine into the tree trunk through the pressurized injection mechanism.

[0012] Preferably, the diameter of the piston corresponds to the inner diameter of the injection needle body, and the piston is slidably installed inside the injection needle body to facilitate drug injection under normal conditions.

[0013] Compared with the prior art, the present invention provides a pressurized drug injection device, which has the following beneficial effects: 1. This pressurized injection device, through its drilling and injection mechanism, enables the hollow drill rod to rotate during use via the transmission between gears and a gear ring. This allows the hollow drill rod to drill a hole inside the tree trunk, inserting the injection needle into the trunk. The short-threaded extension rod then drives the injection needle body towards the tree trunk, allowing the injection needle to leave the hollow drill rod and insert into the trunk. Protected and restrained by the hollow drill rod, the injection needle body can be easily inserted into the trunk without bearing excessive pressure, preventing bending and improving the stability of pressurized injection.

[0014] 2. This pressurized injection device, through its pressurized injection mechanism, uses a cylinder to move a connecting plate during use, causing a push rod to drive a piston to slide inside the injection needle body, allowing the liquid medicine inside the injection needle body to be injected into the trunk, thus realizing the function of pressurized injection of medicine into the trunk.

[0020] The drilling and injection mechanism 2 includes a drilling assembly 21 and a needle assembly 22, with the needle assembly 22 located on the right side of the drilling assembly 21.

[0021] Furthermore, the drilling assembly 21 includes a mounting shell 211, which is fixedly mounted on the top of the handle 1. A mounting shell 212 is fixedly mounted on the outside of the mounting shell 211. A hollow shaft 213 is rotatably mounted inside the mounting shell 211. A hollow drill rod 214 is fixedly mounted on the left side of the hollow shaft 213. A gear ring 215 is fixedly mounted on the outside of the hollow shaft 213. A motor 216 is fixedly mounted on the top of the mounting shell 211. A gear 217 is fixedly mounted on the left side of the drive shaft of the motor 216, which facilitates drilling holes in the tree trunk through the drilling assembly 21.

[0022] Furthermore, the motor 216 is located inside the mounting housing 212, and the gear 217 meshes with the gear ring 215 to facilitate the normal rotation of the hollow drill rod 214.

[0023] Furthermore, the needle insertion assembly 22 includes an injection needle body 221, which is slidably installed inside the mounting shell 211. An injection needle 222 is fixedly installed on the left side of the injection needle body 221. A sliding lug 223 and a threaded lug 225 are fixedly installed on the outside of the injection needle body 221. A limiting rod 224 is slidably installed inside the sliding lug 223. A short-threaded extension rod 226 is installed inside the threaded lug 225. A rotation limiting block 227 is rotatably installed on the outside of the short-threaded extension rod 226. An injection hopper 228 is provided at the top of the injection needle body 221 to facilitate the insertion of the injection needle 222 into the trunk through the needle insertion assembly 22.

[0024] Furthermore, the injection needle 222 is slidably installed inside the hollow drill rod 214, the back of the limiting rod 224 is fixedly installed with the front of the mounting shell 211, and the front of the rotating limiting block 227 is fixedly installed with the back of the mounting shell 211, which improves stability.

[0025] Example 2: Please see Figure 5Furthermore, in conjunction with Embodiment 1, it is further found that the pressurized injection mechanism 3 includes a mounting block 31, which is fixedly installed at the bottom of the injection needle body 221. A cylinder 32 is fixedly installed on the right side of the mounting block 31, a connecting plate 33 is fixedly installed on the right side of the cylinder 32, a push rod 34 is fixedly installed on the left side of the connecting plate 33, and a piston 35 is fixedly installed on the left side of the push rod 34, so as to facilitate pressurized injection of medicine into the tree trunk through the pressurized injection mechanism 3.

[0026] Furthermore, the diameter of the piston 35 corresponds to the inner diameter of the injection needle body 221, and the piston 35 is slidably installed inside the injection needle body 221 to facilitate drug injection under normal conditions.

[0027] In actual operation, when using this device, hold handle 1 and handle 4, and press the hollow drill rod 214 firmly against the tree trunk. Then, drive motor 216, causing its transmission shaft to rotate gear 217. Gear 217 then rotates gear ring 215, allowing the hollow shaft 213 to rotate. As the hollow shaft 213 rotates, the hollow drill rod 214 also rotates, applying pressure to the tree trunk. The hollow drill rod 214 enters the interior of the tree trunk and begins drilling. After drilling is complete, without removing the hollow drill rod 214, rotate the short-cut threaded extension rod 226, and drill along the threaded lug 225. With the threaded connection and the limiting of the sliding lug 223 and the limiting rod 224, the injection needle body 221 moves towards the tree trunk and drives the injection needle 222 to move. The injection needle 222 protrudes from the inside of the hollow drill rod 214 and is inserted into the inside of the tree trunk. At this time, the driving cylinder 32 drives the connecting plate 33 to move, and the connecting plate 33 drives the push rod 34 to move. At this time, the push rod 34 pushes the piston 35 to slide inside the injection needle body 221, so that the medicine can pass through the injection needle 222 and be injected into the inside of the tree trunk. After the pressurized injection is completed, the hollow drill rod 214 can be pulled out.
