Description

Technical Field

[0001] This invention relates to the field of tree pest control technology, specifically to a pest control device for tea tree cultivation. Background Technology

[0002] Arbor tea trees and some small arbor tea trees are susceptible to pest infestation during the planting process. These pests generally hide in the soil during the day, lay eggs at the base of the trunk and in weeds, and emerge at night after hatching. They climb up the trunk and eat the leaves of the tea trees, thus affecting the growth rate of the tea trees and, in severe cases, causing the trees to die.

[0003] According to a public notice (Announcement No.: CN220986908U) of a pest control device for tea tree planting, the above application describes a method of fixing a drip pipe to a tree by inserting a locking pin into a suitable lock hole on a fixing belt and inserting two locking pins on the locking pin into two grooves in the lock hole. The insecticide overflowing from the leak hole on the drip pipe is then used to kill pests on the tea tree.

[0004] However, in actual use, the aforementioned devices rely on gravity or dripping to discharge the insecticide downwards along the tea tree trunk. But due to considerations of dripping time and waste, the number of openings for dripping is generally limited. This means the insecticide dripping from these openings may not be able to completely cover the bark near the roots during gravity-fed descent, leaving gaps for pests to climb upwards in some areas, thus reducing the overall insect-control effect. Therefore, we propose an insect-control device for tea tree cultivation. Summary of the Invention

[0005] The purpose of this invention is to provide a pest control device for tea tree cultivation to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tea tree planting insect control device, comprising an installation ring, wherein an annular drip tube is fixedly connected to the lower surface of the installation ring by a rubber rod, a connecting sleeve is fitted on the outer wall of the annular drip tube, a receiving cavity is opened inside the annular drip tube, a drip nozzle is fixedly installed through the bottom inner wall of the receiving cavity, and a diffusion component is provided inside the annular drip nozzle to control the intermittent discharge of the drip nozzle and maintain the discharge distribution range; The diffusion component includes a small motor, which is fixedly mounted on the upper surface of the annular drip nozzle. A small gear is fixedly mounted on the output end of the small motor. An annular baffle is rotatably mounted on the inner surface of the annular drip tube. A through hole is opened on the inner wall of the annular baffle. A bent rod is rotatably mounted on the upper surface of the annular baffle.

[0007] Preferably, the mounting ring also includes a detachable elastic connecting buckle, allowing the mounting ring to be completely fitted over the outside of the tea tree trunk for easy installation. The elastic connecting buckle's stretchability ensures it fits tightly against the trunk surface, preventing it from falling off or shifting. Similarly, the connecting sleeve is used for sealing the two ends of the annular drip tube and can also be fitted over the outside of the trunk for annular protection. The connecting sleeve is connected to the inner cavity of the annular drip tube, forming a complete passage.

[0008] Preferably, the number of drip nozzles is set to multiple sets, which are evenly distributed in a circumferential array at the bottom of the annular drip tube. The insect repellent drips downward through the drip nozzles under the action of gravity, thereby forming a protective ring of the agent on the outer surface of the tea tree trunk.

[0009] Preferably, the number of through holes is provided in multiple sets, and the multiple sets of through holes are arranged in a circumferential array on the inner surface of the annular baffle. Furthermore, the inner diameter of the through holes is larger than the inner diameter of the drip nozzle, so that the insect repellent in the cavity can be discharged outward through the through holes and the drip nozzle.

[0010] Preferably, the drip nozzle is provided with a horizontally diffused insect repellent spraying component inside. The spraying component includes an annular groove, which is formed on the bottom inner surface of the receiving cavity. A protrusion is fixedly installed on the bottom surface of the annular baffle. A rotating rod is rotatably installed on the inner wall of the drip nozzle. A U-shaped lever is fixedly installed through the rotating rod. A coil spring is sleeved on the outer wall of the rotating rod. A silicone sheet is fixedly installed on the inner surface of the U-shaped lever.

[0011] Preferably, the bottom surface of the protrusion is arc-shaped, and the width of the protrusion is less than the width of the annular groove. The top end of the U-shaped lever is also arc-shaped to prevent the protrusion from getting stuck or interfering with the movement of the annular baffle.

[0012] Preferably, the inner walls on both sides of the drip nozzle are provided with circular holes with a diameter larger than the outer diameter of the coil spring, and the end of the rotating rod is rotatably mounted on the bottom inner wall of the circular hole. The two ends of the coil spring are respectively fixedly connected to the inner wall of the circular hole and the arc-shaped outer wall of the rotating rod. The outer wall of the rotating rod is provided with a circular baffle, and the diameter of the circular baffle is larger than the inner diameter of the circular hole, thereby providing a certain sealing effect for the circular hole.

[0013] Preferably, the bottom outer surface of the annular drip tube is provided with a blocking component, the blocking component including an annular cover, the annular cover being fixedly installed on the bottom outer surface of the annular drip tube, the inner surface of the annular cover having an arc-shaped groove, the bottom inner surface of the annular cover being fixedly installed with an annular mesh cover, the inner surface of the arc-shaped groove having an inclined groove, and the inner surface of the arc-shaped groove having an annular opening.

[0014] Preferably, the outer surface of the annular cover is arc-shaped and smooth, thereby physically preventing pests from climbing directly up the device and providing good protection for the tea trees.

[0015] Compared with the prior art, the present invention provides a pest control device for tea tree cultivation, which has the following beneficial effects: 1. This insect control device for tea tree planting, equipped with a diffusion component, uses a small motor to drive a small gear, which in turn drives an annular baffle to rotate continuously within the receiving cavity. The annular baffle has multiple sets of through holes with an inner diameter larger than the drip nozzle's inner diameter, facilitating even distribution of the pesticide. Simultaneously, multiple sets of curved rods with U-shaped protrusions are installed on the annular baffle, continuously stirring the insect control pesticide within the receiving cavity during rotation. This effectively prevents pesticide sedimentation, ensures uniform pesticide concentration, and avoids the problem of insects climbing through gaps in the trunk due to uneven pesticide distribution. It solves the problem of reduced insect control effectiveness in existing devices due to the limited number of drip holes and incomplete pesticide coverage.

[0016] 2. This tea tree planting pest control device, through the setting of a spreading component, when the protrusion at the bottom of the annular baffle intermittently pushes the U-shaped lever as it rotates, it rotates around the rotating rod and quickly resets under the action of the coil spring. The silicone sheet on the inner side of the U-shaped lever swings in a fan shape due to inertia, throwing out the accumulated pesticide over a wider range, significantly expanding the horizontal diffusion area of ​​the pesticide on the trunk surface, ensuring that the bark near the roots is fully covered, solving the problem in existing equipment where the pesticide relies solely on gravity to flow down, has a limited coverage area, and is difficult to effectively block all pest climbing paths.

[0017] 3. This insect control device for tea tree planting incorporates a barrier component. An inclined groove allows the pesticide to flow tangentially, expanding its distribution range on the annular mesh cover. The annular opening temporarily retains some of the pesticide, allowing it to slowly evaporate within the cover, creating a continuous insect-controlling atomized space. Simultaneously, the smooth, curved outer surface of the annular cover physically prevents pests from directly climbing. These multiple measures work together to enhance the sustainability and reliability of the overall insect control, solving the problem of existing devices relying solely on pesticide dripping and lacking physical barriers and continuous pesticide evaporation protection, resulting in unsustainable and incomplete insect control.

[0020] like Figures 1-7 As shown, the present invention provides a technical solution: a tea tree planting insect control device, including an installation ring 1, an annular drip tube 2 fixedly connected to the lower surface of the installation ring 1 by a rubber rod, a connecting sleeve 3 sleeved on the outer wall of the annular drip tube 2, a receiving cavity 4 opened inside the annular drip tube 2, a drip nozzle 5 through and fixedly installed on the bottom inner wall of the receiving cavity 4, and a diffusion component 6 inside the annular drip nozzle 5 to control the intermittent discharge of the drip nozzle 5 and maintain the discharge distribution range, the diffusion component 6 including a small motor 601, a small gear 602, an annular baffle 603, a through hole 604 and a bent rod 605.

[0021] In one embodiment of the present invention, a small motor 601 is fixedly installed on the upper surface of the annular drip nozzle 5, a small gear 602 is fixedly installed at the output end of the small motor 601, an annular baffle 603 is rotatably installed on the inner surface of the annular drip tube 2, a through hole 604 is opened on the inner wall of the annular baffle 603, and a bent rod 605 is rotatably installed on the upper surface of the annular baffle 603.

[0022] Furthermore, the installation ring 1 also includes a detachable elastic connecting buckle, allowing the installation ring 1 to be completely fitted onto the outside of the tea tree trunk for easy overall installation. The elastic connecting buckle's stretchability ensures it fits tightly to the trunk surface, preventing it from falling off or shifting. Similarly, the connecting sleeve 3 seals both ends of the annular drip tube 2 and can also be fitted onto the outside of the trunk for annular protection. Specifically, the connecting sleeve 3 is connected to the inner cavity of the annular drip tube 2, forming a complete passageway, thus providing storage space for the tea tree insecticide in conjunction with the receiving cavity 4. Additionally, multiple sets of drip nozzles 5 are arranged in a circumferential array at the bottom of the annular drip tube 2. Under gravity, the insecticide drips downwards through the drip nozzles 5, forming a protective ring on the outer surface of the tea tree trunk to prevent pests at the roots from climbing upwards along the trunk surface and damaging the tea tree.

[0023] In addition, an annular toothed ring is provided on one side of the annular baffle 603, and the annular toothed ring meshes with the pinion 602 to achieve transmission. By starting the small motor 601, the pinion 602 is controlled to drive the annular baffle 603 to rotate continuously on the inner surface of the receiving cavity 4. At the same time, the width of the annular baffle 603 is adapted to the width of the receiving cavity 4. Furthermore, multiple sets of through holes 604 are provided, and the multiple sets of through holes 604 are arranged in a circumferential array on the inner surface of the annular baffle 603. The inner diameter of the through holes 604 is larger than the inner diameter of the drip nozzle 5, so that the insect repellent in the receiving cavity 4 can be discharged outward through the through holes 604 and the drip nozzle 5, thereby achieving the effect of insect prevention for tea trees.

[0024] Specifically, the middle section of the bent rod 605 is provided with a U-shaped protrusion, and there are multiple sets of bent rods 605 arranged in a circumferential array. The multiple sets of bent rods 605 are spaced apart from the through hole 604. Thus, during the continuous rotation of the annular baffle 603, the bent rod 605 with the U-shaped protrusion will not remain stationary, but will rotate continuously with the connection between it and the annular baffle 603 as the center of rotation. This stirs the insect repellent in the receiving cavity 4, prevents it from settling, ensures the uniformity of the agent distribution, and avoids sedimentation.

[0025] Please see Figures 4-6 The drip nozzle 5 is equipped with a horizontally diffused insect repellent spraying component 7. The spraying component 7 includes an annular groove 701, which is formed on the bottom inner surface of the receiving cavity 4. A protrusion 702 is fixedly installed on the bottom surface of the annular baffle 603. A rotating rod 703 is rotatably installed on the inner wall of the drip nozzle 5. A U-shaped lever 704 is fixedly installed through the rotating rod 703. A coil spring 705 is sleeved on the outer wall of the rotating rod 703. A silicone sheet 706 is fixedly installed on the inner surface of the U-shaped lever 704.

[0026] In an embodiment of the present invention, the bottom surface of the protrusion 702 is arc-shaped, and the width of the protrusion 702 is smaller than the width of the annular groove 701. The top end of the U-shaped lever 704 is arc-shaped to prevent the protrusion 702 from getting stuck or interfering with the movement of the annular baffle 603. Furthermore, circular holes with a diameter larger than the outer diameter of the coil spring 705 are provided on the inner walls of both sides of the drip nozzle 5. The end of the rotating rod 703 is rotatably mounted on the inner wall of the bottom of the circular hole. The two ends of the coil spring 705 are fixedly connected to the inner wall of the circular hole and the arc-shaped outer wall of the rotating rod 703, respectively. Specifically, a circular baffle is provided on the outer wall of the rotating rod 703, and the diameter of the circular baffle is larger than the inner diameter of the circular hole, thereby providing a certain sealing effect on the circular hole and preventing insect repellent from entering the circular hole and adversely affecting the normal use of the coil spring 705.

[0027] Furthermore, the silicone sheet 706 is U-shaped. When the protrusion 702 moves, it touches the top of the U-shaped lever 704, causing it to rotate around the rotating rod 703. Then, under the elastic force of the coil spring 705, it rotates in the opposite direction. Due to inertia, the silicone sheet 706 will make a relatively delayed fan-shaped oscillation during the rotation of the U-shaped lever 704. The insect repellent accumulated in the U-shaped cavity of the silicone sheet 706 will have a wider diffusion range due to inertia. This allows the silicone sheet 706 in the several drip nozzles 5 arranged around the bottom of the annular drip tube 2 to expand the spraying range of the agent, covering the bark of the tea tree trunk near the roots, effectively preventing pests from climbing up the bark of the trunk and damaging the tea tree.

[0028] Please see Figure 3 as well as Figure 7 The bottom outer surface of the annular drip tube 2 is provided with a blocking component 8. The blocking component 8 includes an annular cover 801, which is fixedly installed on the bottom outer surface of the annular drip tube 2. An arc-shaped groove 802 is opened on the inner surface of the annular cover 801. An annular mesh cover 804 is fixedly installed on the bottom inner surface of the annular cover 801. An inclined groove 803 is opened on the inner surface of the arc-shaped groove 802. An annular opening 805 is opened on the inner surface of the arc-shaped groove 802.

[0029] In an embodiment of the present invention, the top surface of the annular cover 801 is in contact with the bottom surface of the annular drip tube 2, while the annular mesh cover 804 is disposed between the annular cover 801 and the tree trunk bark. The inner walls of the upper and lower sides of the annular mesh cover 804 are provided with several small mesh holes to allow the dripping insect repellent to pass smoothly and protect the tree trunk bark. Furthermore, multiple sets of inclined grooves 803 are provided, evenly distributed in a circumferential array on the inner surface of the arc-shaped groove 802. The inclined grooves 803 allow the dripping insect repellent to flow smoothly along the inner surface of the inclined grooves 803. The insecticide flows out in a direction tangential to the bottom of the ring cover 801, allowing it to have a wider diffusion range on the ring cover 804. The ring openings 805 are set in multiple sets, and the multiple sets of ring openings 805 are evenly distributed in the vertical direction on the inner surface of the arc groove 802. This allows the ring openings 805 to temporarily retain some of the downward-flowing insecticide. This part of the insecticide will not diffuse directly downwards, but will remain inside the ring cover 801 and eventually evaporate and be released. This will also have a continuous insect-repellent misting effect on the periphery of the ring cover 801, forming an insect-repellent space and protecting the tree trunk from pests.

[0030] It is worth noting that the outer surface of the annular cover 801 is arc-shaped and smooth, which physically prevents pests from climbing directly up the device, thus providing good protection for the tea trees.

[0031] In this invention, when in use, the installation ring 1 is first fitted onto the outside of the tea tree trunk through its detachable elastic connecting buckle, so that it fits tightly against the surface of the trunk to prevent the device from shifting or falling off. The annular drip tube 2 is connected to the installation ring 1 through the connecting sleeve 3. Its internal receiving cavity 4 is used to store insect repellent. Under the action of gravity, the insect repellent drips down through the drip nozzle 5, forming a protective layer of insect repellent on the surface of the trunk to prevent pests from climbing up from the roots. The diffusion component 6 is used to control the uniform distribution of the agent and prevent precipitation. The small motor 601 is started, which drives the pinion 602 to rotate, thereby driving the annular baffle 603 to rotate continuously in the receiving cavity 4. The annular baffle 603 is provided with multiple sets of through holes 604, the inner diameter of which is larger than the inner diameter of the drip nozzle 5, so as to facilitate the flow of the agent. At the same time, multiple sets of bent rods 605 are installed on the annular baffle 603. The U-shaped protrusions stir the agent in the receiving cavity 4 during rotation to prevent the agent from settling and ensure uniform agent concentration. The spraying component 7 is used to expand the horizontal diffusion range of the agent. When the protrusion 702 at the bottom of the annular baffle 603 rotates, it will intermittently push the U-shaped lever 704, causing it to rotate around the rotating rod 703. A coil spring 705 is sleeved on the rotating rod 703. After the protrusion 702 leaves, the coil spring 705 causes the U-shaped lever 704 to quickly return to its original position. A silicone sheet 706 is fixed inside the U-shaped lever 704. During the swinging process, due to inertia, it throws out the accumulated agent in a fan shape, expanding the agent coverage area and ensuring that the bark of the tree trunk is fully protected. The barrier component 8 further enhances the insect-proof effect. The annular cover 801 is fixed to the bottom of the annular drip tube 2, and an annular mesh cover 804 is provided on its inner side to facilitate the passage of the pesticide and its adhesion to the tree trunk surface. The arc-shaped groove 802 is provided with multiple sets of inclined grooves 803, which allow the pesticide to flow out in the tangential direction and expand the coverage area. The annular opening 805 temporarily retains part of the pesticide, allowing it to slowly evaporate in the annular cover 801, forming a continuous insect-proof atomized space. In addition, the outer surface of the annular cover 801 has a smooth arc design, which physically blocks pests from climbing directly, further improving the overall insect-proof effect.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
