Description

Technical Field

[0001] This utility model relates to the field of seedling planting technology, specifically a tree ring spraying device. Background Technology

[0002] During the cultivation of wolfberry, the trunk and base of the root system are high-risk areas for pests and diseases. For example, wolfberry aphids, wolfberry psyllids, and wolfberry gall mites often lay eggs or inhabit the branches and trunks. Root rot and other diseases also require pesticide application to the root system for prevention. Currently, pesticide application in wolfberry orchards generally uses large sprayers or manual backpack sprayers. Large sprayers are mainly used for spraying the canopy and leaves, but they have poor coverage of the base of the trunk close to the ground, and the pesticide solution is severely scattered. They also have insufficient penetration in densely planted wolfberry orchards.

[0003] The existing patent announcement number CN221729494U discloses a seedling spraying device for landscaping projects, which "includes a trolley, on which a storage tank and a water pump are installed. The top of the storage tank is equipped with a sealing cap. The water pump has a first hose at its inlet and a second hose at its outlet. The bottom of the sealing cap is equipped with a connecting mechanism. The top of the sealing cap is equipped with a forward and reverse motor. Above the forward and reverse motor is a turntable. The bottom of the turntable is equipped with a rotating rod. One end of the top of the turntable is equipped with a first guide plate and a second guide plate." The invention, by setting up a forward and reverse motor, a turntable, a first guide plate, a second guide plate, a guide hole, a controller, and a connecting mechanism, can further improve the ease of adjusting the spraying angle of the nozzle of the seedling spraying device for landscaping projects. However, it can only spray the trunk area with a single nozzle, and cannot achieve uniform coverage of the trunk circumference. It is easy to have missed areas, which affects the prevention and control effect. At the same time, the pesticide solution is seriously scattered during spraying, which not only causes waste, but also pollutes the surrounding environment and poses a threat to the health of operators.

[0004] Based on this, a tree ring spraying device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-5 As shown, a tree ring spraying device includes a spraying assembly. A drug inlet pipe 3 is provided on one side of the spraying assembly. A connector 4 is fixedly connected to the lower end of the drug inlet pipe 3 and is detachably connected to a drug storage tank.

[0027] The spraying assembly includes two annular seats 1 arranged symmetrically. Each annular seat 1 is semi-circular. Several atomizing nozzles 2 are arrayed on the inner side of each annular seat 1. An annular flow channel is formed inside each annular seat 1. The inlet pipe 3 is connected to the annular flow channel. Each atomizing nozzle 2 is connected to the annular flow channel to uniformly deliver the liquid medicine to each atomizing nozzle. A hinge seat 5 is provided at one adjacent end of each of the two annular seats 1 and they are hinged to each other through the hinge seat 5. A snap-fit ​​assembly is provided at the other adjacent end of each of the two annular seats 1. The snap-fit ​​assembly includes a fixing seat 11. One end of the fixing seat 11 is fixedly connected to one side of the adjacent annular seat 1. A snap-fit ​​seat 12 is provided on one side of the fixing seat 11 and is fixedly connected to one side of the adjacent annular seat 1. A limiting groove 13 is formed on one side of the snap-fit ​​seat 12. A limiting post 15 is fixedly connected to the side of the fixing seat 11 adjacent to the limiting groove 13 and is slidably connected to the inner side of the limiting groove 13.

[0028] In this embodiment, the operator unfolds the two annular seats 1 like opening a book using the hinge seat 5, covers the tree trunk, and then closes the other end through the buckle assembly. The limiting post 15 on the fixed seat 11 is inserted into the limiting groove 13 of the buckle seat 12 to achieve initial alignment and connection. After the medicine is introduced into the medicine tube 3, the medicine is distributed to the internal cavity of the two annular seats 1 and sprayed simultaneously towards the center of the tree trunk by multiple atomizing nozzles 2 evenly distributed on the inner side of the annular seats 1, thereby achieving uniform 360-degree coverage of the tree trunk with medicine and solving the problem of uneven spraying on one side.

[0029] In one embodiment, such as Figure 5 As shown, a through groove 20 is provided on one side of the limiting post 15, and a sliding groove 16 is provided on one side of the through groove 20. A pair of pressing plates 18 are slidably arranged on both sides of the sliding groove 16, and a pair of latching posts 17 are slidably arranged on both sides of the through groove 20. One side of each latching post 17 is fixedly connected to the adjacent pressing plate 18. A spring 19 is fixedly connected between the two latching posts 17. When the device needs to be closed, the operator pinches the two pressing plates 18 with their fingers, causing them to slide towards each other in the sliding groove 16. The pressing plates 18 drive the latching posts 17 fixed to them to move in the through groove 20 and compress the spring 19 located therebetween. At this time, the ends of the latching posts 17 retract, and the limiting post 15 can be inserted into the limiting groove 13 without obstruction. When the limiting post 15 is in place, the pressing plates 18 are released, and the compressed spring 19 releases its elasticity, pushing the two latching posts 17 to move in opposite directions, causing them to pop outward and completing the automatic locking.

[0030] In one embodiment, such as Figure 5As shown, a latching groove 14 is provided on both sides of the limiting groove 13. Each latching groove 14 is slidably connected to the adjacent latching post 17. When the latching post 17 is ejected outward under the action of the spring 19, its end will accurately engage in the latching groove 14 on the inner side wall of the limiting groove 13. The latching groove 14 forms circumferential and axial constraints on the latching post 17, just like a door bolt inserted into a door bolt hole, ensuring that the fixing seat 11 and the latching seat 12 will not easily separate due to external force, which greatly enhances the structural stability and reliability of the annular seat 1 in the closed state and ensures the sealing and uniformity of the spraying process.

[0031] In one embodiment, such as Figure 5 As shown, the end of each of the latching posts 17 adjacent to the latching groove 14 is set as an inclined side. The end of the latching post 17 that mates with the latching groove 14 is designed as an inclined side so that during the closing process, even without squeezing the pressing plate 18, the inclined side can generate a guiding force when it contacts the edge of the latching seat 12, which automatically guides the latching post 17 to retract inward until it slides into the position of the latching groove 14 and then quickly springs back and locks under the action of the spring 19.

[0032] In one embodiment, such as Figure 1 As shown, a collection component is provided below the annular seat 1. When the annular seat 1 sprays, some of the atomized liquid will drip down if it is not absorbed by the bark of the tree trunk in time. The collection component located directly below the annular seat 1 has a closed plate 6 that acts as a protective top plate. It first receives and guides the dripping liquid to prevent it from contaminating the device body or splashing everywhere, and then guides it to the collection chamber 7 below for centralized treatment, thus realizing the initial recovery of the liquid and environmental protection.

[0033] In one embodiment, such as Figure 3 As shown, the collection assembly includes two sealing plates 6, each fixedly connected to the lower surface of an adjacent annular seat 1. Each sealing plate 6 has a collection chamber 7 fixedly connected to its lower end, and a baffle plate 9 fixedly connected to one side of the upper surface of each collection chamber 7. Sealing strips are provided at adjacent ends of the two sealing plates 6; when closed, the sealing strips abut against each other to prevent leakage of the medicine. The two sealing plates 6 are fixed to the bottom of the two annular seats 1 and move with their opening and closing. After being blocked by the sealing plates 6, the dripping medicine flows into the fixed collection chamber 7 below them. The baffle plate 9 on the upper side of the collection chamber 7 further prevents horizontal splashing of the medicine, ensuring that all dripping medicine is confined within the semi-enclosed space formed by the sealing plates 6, collection chambers 7, and baffle plates 9, thus creating conditions for subsequent collection and recycling.

[0034] In one embodiment, such as Figure 3As shown, the upper surface of the collection chamber 7 is provided with a number of collection grooves 10. The multiple collection grooves 10 formed by these grooves constitute a flow guiding network, so that the medicine dripped into the collection chamber 7 will not flow randomly, but will quickly flow into these collection grooves 10 under the action of gravity.

[0035] In one embodiment, such as Figure 3 As shown, a medicine outlet pipe 8 is fixedly connected to one end of the collection chamber 7. The medicine outlet pipe 8, fixed to one end of the collection chamber 7, serves as the final outlet of the collection system. All remaining medicine liquid that flows through the collection tank 10 will be collected at the inlet of the medicine outlet pipe 8. Operators can connect hoses or containers to the outside of the medicine outlet pipe 8 to orderly export these medicine liquids for unified treatment or recycling, thus completely avoiding the direct discharge of medicine liquids into the environment and achieving the dual goals of energy conservation, environmental protection, and cost control.

[0036] The above embodiment discloses a tree ring spraying device. In use, the operator holds the device and applies outward force to move the two squeezing plates 18 towards each other. The squeezing plates 18 drive the locking posts 17 to compress the springs 19 and retract into the through grooves 20, allowing the limiting posts 15 to smoothly insert into or retract from the limiting grooves 13 on the locking seats 12, thus opening and closing the device. After the device is placed around the tree trunk to be sprayed, the squeezing plates 18 are released. The rebound force of the springs 19 pushes the locking posts 17 outward, causing them to engage with the sides of the limiting grooves 13. The locking mechanism is completed in the snap-fit ​​slot 14. Then, the connector 4 is connected to the external storage tank and pump group. The liquid medicine enters the internal flow channel of the two annular seats 1 through the inlet pipe 3. Finally, it is sprayed out by multiple atomizing nozzles 2 arrayed on the inner side of the annular seats 1, forming a uniform liquid mist around the tree trunk. During the application process, the liquid medicine that is not absorbed by the tree trunk and drips down is blocked and guided by the sealing plate 6 below. It flows through the collection groove 10 on the upper surface of the collection chamber 7 and falls into the collection chamber 7. Finally, it is discharged through the outlet pipe 8 and can be recycled. The baffle plate 9 can prevent the liquid medicine from splashing out from the front.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
