Description

Technical Field

[0001] This utility model belongs to the field of ginkgo planting technology, specifically relating to a spraying and insecticidal device for cultivating ginkgo seedlings. Background Technology

[0002] Cultivating ginkgo seedlings is for the large-scale, standardized production of ginkgo leaf raw materials used in pharmaceuticals and health products. Ginkgo leaf extracts (containing flavonoids and ginkgolides) are important raw materials for cardiovascular and cerebrovascular disease drugs, with huge market demand. However, the number of wild ginkgo trees is limited and scattered, unable to meet the needs of industrial production. Cultivating seedlings allows for the establishment of large-scale, standardized medicinal ginkgo plantations. Compared to mature trees, ginkgo seedlings are more fragile and less resistant, making them highly susceptible to pests and diseases. Therefore, regular spraying with pesticides is necessary for pest and disease control.

[0003] Ginkgo seedlings are short and have dense foliage, especially in the seedling stage where leaves grow in clusters. Traditional top-down spraying methods make it difficult for pesticides to penetrate evenly and cover the undersides and denser areas of the leaves. Pests (such as aphids, spider mites, and leafroller larvae) prefer to inhabit these hidden areas, resulting in "safe zones" after spraying. The pesticide cannot penetrate the canopy, creating many blind spots that require repeated manual spraying from multiple angles, leading to low efficiency and significantly reduced control effectiveness. Furthermore, nursery areas are typically large, and relying on manual backpack sprayers is labor-intensive and inefficient. Utility Model Content

[0004] To overcome the problem that traditional spraying methods for controlling pests and diseases in ginkgo seedlings often fail to evenly cover the undersides and hidden areas of the leaves with pesticides, this invention provides a spraying and insecticidal device for ginkgo seedling cultivation. This device, through its multi-angle and multi-layer spraying design, solves the technical difficulties of poor pesticide penetration and uneven coverage. Furthermore, the use of a trolley structure reduces manual labor intensity and improves operational efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A spraying and insecticidal device for cultivating ginkgo seedlings mainly includes a trolley, a protective railing, a medicine tank, a support plate, a support rod, a medicine extraction mechanism, a three-dimensional spraying unit, a battery, and a controller. The trolley is equipped with casters at the bottom and push-pull handles at the ends. The casters are equipped with brake devices for fixing their position during operation. The protective railing is installed around the top of the trolley with fastening bolts, forming a protective space for the medicine tank to prevent it from slipping off the top of the trolley during spraying. The medicine tank is installed on the top of the trolley, inside the protective railing, and is used to store the pesticide solution. A support plate is welded to the top of the protective railing, and the medicine extraction mechanism is installed on the support plate. The support rod is also installed on the support plate. The three-dimensional spraying unit is horizontally installed on the support rod via retaining rings. The medicine extraction mechanism and the three-dimensional spraying unit are connected through pipes, and the pesticide solution is transported to the three-dimensional spraying unit through the medicine extraction mechanism. The battery and controller are mounted on the support plate. The drug extraction mechanism is electrically connected to the controller. The push-pull handle is equipped with a control switch, which is electrically connected to the controller. The signal is transmitted to the controller, allowing the operator to control the start and stop of the drug extraction mechanism when pushing the cart. The described pesticide extraction mechanism includes a water pump, an inlet pipe, and an outlet pipe. The water pump is installed on the top of the support plate. One end of the inlet pipe is inserted into the inside of the pesticide tank, and the other end is connected to the inlet end of the water pump through a pipe joint. One end of the outlet pipe is connected to the outlet end of the water pump, and the other end is connected to the three-dimensional spraying unit. The three-dimensional spraying unit includes a water supply pipe, a retaining ring, a branch pipe, a top nozzle, and side nozzles. The water supply pipe is horizontally mounted on a support rod via the retaining ring, and both ends of the water supply pipe are equipped with detachable sealing heads. The outlet pipe is connected to the water supply pipe. Multiple branch pipes are installed vertically downwards at equal intervals along the length of the water supply pipe and are connected to the inside of the water supply pipe via threaded joints. The cross-section of each branch pipe is a semi-closed rectangular tubular structure. A top nozzle is installed at the bottom center of each branch pipe for conventional top-down spraying. Multiple side nozzles are staggered and threadedly installed on both sides of each branch pipe. The spray axis of the side nozzles forms an elevation or depression angle of 10° to 60° with the vertical direction to generate intersecting, bottom-up or horizontal jets of pesticide solution, covering the back and hidden areas of the seedling branches and leaves. The top nozzle is a conical atomizing nozzle with a wide and uniform spray range, while the side nozzles are either atomizing nozzles or fan-shaped nozzles, allowing the spraying mode to be adjusted according to actual needs.

[0006] The number of diversion pipes can be increased or decreased according to the width of the seedbed. The spacing between the diversion pipes matches the planting row spacing of the ginkgo seedlings to ensure that each seedling is fully covered. The medicine box has a transparent observation window on its side wall with volume markings to facilitate real-time monitoring of the remaining liquid. The top of the medicine box has a filling port equipped with a sealing cap to prevent liquid evaporation or contamination. The beneficial effects of this utility model are: This invention utilizes a three-dimensional spraying unit to cover the branches and leaves of ginkgo seedlings with pesticide from multiple angles, especially the undersides and hidden areas inside the leaves. The top nozzle handles conventional top-down spraying, while the side nozzles spray at specific angles, compensating for the shortcomings of traditional spraying methods. The trolley, combined with casters and push-pull handles, makes the entire device highly mobile and suitable for large-scale seedling nurseries, reducing manual labor intensity and improving spraying efficiency. At the same time, the multi-angle spraying solves the problem of uneven pesticide coverage, significantly improving the effectiveness of pest and disease control. Attached Figure Description

[0012] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0013] This utility model discloses a spraying and insecticidal device for cultivating ginkgo seedlings. The device mainly includes a cart 1, a protective railing 2, a pesticide tank 3, a support plate 4, a support rod 5, a pesticide extraction mechanism 6, a three-dimensional spraying unit 7, a battery 8, and a controller 9. The cart 1 has four casters 10 installed at its bottom, with two front wheels and two rear wheels located at the four corners of the bottom. The casters 10 are bolted to the base of the cart 1 and equipped with brakes to maintain the device's position during operation. A push-pull handle 11 is welded to the end of the cart 1, and a control switch 13 is installed on the top of the handle 13. The control switch 13 is electrically connected to the controller 9 via a wire. The protective railing 2 is installed around the top of the cart 1 with fastening bolts, forming a closed protective space to prevent the pesticide tank from slipping during spraying.

[0014] The medicine tank 3 is located at the top center of the cart 1, with a transparent observation window 22 on the side wall. The window is marked with volume scales to monitor the remaining medicine volume in real time. A filling port is located on the top of the medicine tank 3, and a sealing cap 23 is installed at the filling port. A rubber gasket is installed on the inside of the sealing cap 23 to enhance the sealing performance. A support plate 4 is welded to the top of the guardrail 2. The support plate 4 is a rectangular steel plate, and the support rod 5 is a cylindrical steel pipe. Its bottom is fixedly connected to the support plate 4. The three-dimensional spraying unit 7 is connected to the support rod 5 via a retaining ring 12.

[0015] like Figure 2 , Figure 3 As shown, the medicine extraction mechanism 6 is installed on the top of the support plate 4. The medicine extraction mechanism 6 includes a water pump 14, an inlet pipe 15, and an outlet pipe 16. The water pump 14 is installed on the top of the support plate 4. One end of the inlet pipe 15 is connected to the inlet end of the water pump 14 through a pipe joint, and the other end is inserted into the medicine tank 3. One end of the outlet pipe 16 is connected to the outlet end of the water pump 14 through a pipe joint, and the other end is connected to the water delivery pipe 17. The battery 8 and the controller 9 are installed on the top of the support plate 4. The battery 8 is electrically connected to the water pump 14 through wires. The controller 9 is electrically connected to the battery 8 and the control switch 13 through wires. The control switch 13 is used to control the start and stop of the water pump 14.

[0016] like Figure 2 , Figure 3 , Figure 4As shown, the three-dimensional spraying unit 7 is horizontally mounted on the support rod 5 via retaining rings 12. The three-dimensional spraying unit 7 includes a water supply pipe 17, a diversion pipe 18, a top nozzle 19, and side nozzles 20. The water supply pipe 17 is a cylindrical steel pipe with detachable sealing heads 21 at both ends. Multiple diversion pipes 18 are installed vertically downwards at equal intervals along the length of the water supply pipe 17. The diversion pipes 18 are connected to the interior of the water supply pipe 17 via threaded joints. The cross-section of the diversion pipe 18 is a semi-closed rectangular tubular structure. A top nozzle 19 is installed at the bottom center of each diversion pipe 18. The top nozzle 19 is a conical atomizing nozzle with a wide and uniform spray range. Multiple side nozzles 20 are staggered on the two side walls of each diversion pipe 18. The side nozzles 20 are atomizing nozzles or fan-shaped nozzles, and their spray axes are at an elevation angle of 10° to 60° with the vertical direction to generate intersecting bottom-up or horizontal liquid jets.

[0017] In practice, the operator first injects the liquid medicine into the medicine tank 3 through the filling port, observes the amount of medicine through the transparent observation window 22, and then tightens the sealing cap 23. The operator pushes the cart 1 to the ginkgo seedling planting area and starts the water pump 14 by pushing and pulling the control switch 13 on the handle 11. The water pump 14 draws the liquid medicine from the medicine tank 3 and delivers it through the inlet pipe 15 to the outlet pipe 16, and then through the outlet pipe 16 into the delivery pipe 17. The liquid medicine is distributed to the various distribution pipes 18 through the delivery pipe 17. The top nozzle 19 is responsible for regular spraying from top to bottom, while the side nozzles 20 spray at a specific angle to cover the back of the seedling branches and leaves and the hidden areas inside. The number of distribution pipes 18 can be increased or decreased according to the width of the seedbed, and the spacing between the distribution pipes 18 matches the planting row spacing of the ginkgo seedlings to ensure that each seedling is fully covered. After the spraying operation is completed, the operator can turn off the water pump 14 by controlling switch 13, and the trolley 1 can be moved to the next work area or storage location by using casters 10.

[0018] Work process: In the ginkgo seedling cultivation base, the operator first injects the liquid medicine into the medicine tank 3 through the liquid inlet. The transparent observation window 22 allows the operator to observe the amount of liquid medicine injected in real time and ensure that it meets the needs of the spraying operation. After the liquid medicine is added, the operator tightens the sealing cap 23. The rubber gasket on the inside of the sealing cap 23 enhances the sealing performance and prevents the liquid medicine from leaking or evaporating during transportation. The operator pushes the cart 1 to the ginkgo seedling planting area. The four universal wheels 10 installed at the bottom of the cart 1 make the device move flexibly, and the equipped braking device can fix the position of the device to ensure the stability during the spraying operation.

[0019] Once the device reaches the designated work area, the operator starts the water pump 14 via the control switch 13 on the push-pull handle 11. Upon receiving the signal, the controller 9 controls the battery 8 to supply power to the water pump 14, which then begins operation. The pesticide solution is drawn from the tank 3 through the inlet pipe 15 to the water pump 14, and then transported through the outlet pipe 16 to the delivery pipe 17. The sealing caps 21 at both ends of the delivery pipe 17 ensure that the pesticide solution does not leak. The solution is evenly distributed within the delivery pipe 17 to the various distribution pipes 18. The number of distribution pipes 18 can be adjusted according to the width of the seedbed, and the spacing between the distribution pipes 18 matches the planting row spacing of the ginkgo seedlings, ensuring that each seedling is fully sprayed. For example, in cases where the seedbed is wide, the number of distribution pipes 18 can be increased to expand the spraying range; conversely, in cases where the seedbed is narrow, the number of distribution pipes 18 can be reduced to conserve pesticide solution. This allows the device to adapt to planting areas of different sizes, improving its applicability. The top nozzle 19 is a conical atomizing nozzle, which allows the liquid to be sprayed from top to bottom in a wide and uniform manner, covering the top leaves of the ginkgo seedlings. At the same time, multiple side nozzles 20 are staggered on the two side walls of each diversion pipe 18. The side nozzles 20 are atomizing nozzles or fan-shaped nozzles, and their spray axis is at an elevation angle of 10° to 60° with the vertical direction. This allows the liquid to generate cross-shaped jets from bottom to top or horizontally, accurately covering the back of the seedling branches and leaves and the hidden areas inside. Through the synergistic effect of the top nozzle 19 and the side nozzles 20, the liquid can not only evenly cover the front of the leaves, but also effectively penetrate to the back of the leaves and dense areas of branches and leaves, solving the problem that traditional spraying methods are difficult to cover hidden areas.

[0020] After completing the spraying operation in the current area, the operator turns off the water pump 14 by controlling switch 13, and then uses the casters 10 at the bottom of the trolley 1 to move the device to the next work area. The flexibility of the casters 10 allows the device to be quickly moved within the seedling base, significantly reducing the intensity of manual operation and improving work efficiency.

[0021] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
