Description

Technical Field

[0001] This utility model relates to the technical field of pest and disease control equipment, and in particular to a pesticide application device for preventing potato pests and diseases. Background Technology

[0002] Potatoes are an important food crop widely cultivated globally. However, during their growth, potatoes are frequently attacked by various diseases and pests, such as late blight, early blight, scab, and bacterial wilt, as well as pests like grubs, wireworms, aphids, whiteflies, ladybugs, and beet armyworms. These diseases and pests not only affect potato yield but also reduce its quality, causing serious economic losses to agricultural production.

[0003] To effectively control these pests and diseases, farmers typically use chemical pesticides for spraying. Traditional application devices, such as manual sprayers, tractor-trailer sprayers, or push-type sprayers, while capable of controlling pests and diseases to some extent, have several problems in practical application. For example, during spraying, the atomized pesticide tends to spread in all directions, failing to accurately cover the target crop. This results in a large amount of pesticide falling into the soil, wasting pesticides and increasing the potential risk of environmental pollution. Utility Model Content

[0004] The purpose of this invention is to provide a pesticide application device for preventing potato diseases and pests. By using protective components on both sides, the device reduces the spread of pesticide solution and collects and recycles the solution, thus solving the problems of pesticide waste and potential environmental pollution risks.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A pesticide application device for preventing potato diseases and pests includes a support plate, a moving mechanism at the lower end of the support plate, protective components at both ends of the moving mechanism, the moving mechanism being able to drive the two protective components to move towards or in opposite directions, a spraying mechanism on the inner side of the protective components, a liquid storage tank at the upper end of the support plate, a first water pump inside the liquid storage tank, the spraying mechanism being connected to the first water pump, and a shielding cloth between the two protective components, the shielding cloth being located at the upper end of the spraying mechanism;

[0007] The protective assembly includes a vertical plate, a base plate, an inlet pipe, a second water pump, a filter screen, and a baffle. The upper end of the vertical plate is connected to the moving mechanism, and the base plate is connected to the inner side of the lower end of the vertical plate. The base plate is L-shaped. The baffle is located at both ends of the vertical plate and the base plate, extending to the inner side of the vertical plate and the base plate. The base plate, the baffle, and the vertical plate form a water collection cavity with an open upper end. A water collection trough is provided at the bottom of the water collection cavity. The lower end of the water collection trough is connected to one end of the inlet pipe. The filter screen is located at the open end of the water collection trough. The other end of the inlet pipe is connected to the second water pump, and the second water pump is connected to the storage tank.

[0008] By adopting the above technical solution, the protective components set on both sides restrict the liquid medicine to prevent it from spreading to both sides, and collect the liquid medicine that has spread to both sides for recycling.

[0009] A further feature of this invention is that the upper end of the upright plate is rotatably connected to the moving mechanism, a telescopic motor is rotatably connected to the inner side of the upright plate, and the other end of the telescopic motor is rotatably connected to the moving mechanism.

[0010] By adopting the above technical solution, the telescopic motor drives the upright plate to rotate, forming a trapezoid that is larger at the top and smaller at the bottom, making it fit the plant better and ensuring the effect of pesticide application.

[0011] A further configuration of this utility model is as follows: the moving mechanism includes a bidirectional lead screw, a first slider, a second slider, and a rotary motor; the lower end of the support plate has a left-right oriented groove with an open lower end; the bidirectional lead screw is disposed in the groove; one end of the bidirectional lead screw is rotatably connected to the support plate; the other end of the bidirectional lead screw is connected to the rotary motor; the rotary motor is disposed within the support plate; the first slider and the second slider are respectively connected to the left and right ends of the bidirectional lead screw; both the first slider and the second slider are threadedly connected to the bidirectional lead screw; the first slider and the second slider are slidably connected to the groove; and two telescopic motors are rotatably connected to the first slider and the second slider, respectively.

[0012] By adopting the above technical solution, the two upright plates can be moved towards or away from each other by rotating the motor to accommodate plants of different widths.

[0013] A further feature of this invention is that: a reinforcing rod oriented forward and backward is provided in the middle of the shielding cloth; a movable block is connected to the upper middle of the reinforcing rod; a sliding rod oriented left and right is provided in the sliding groove; the sliding rod is slidably engaged with the first slider and the second slider; the movable block is slidably engaged with the sliding rod; the movable block can slide left and right; a first spring and a second spring are respectively provided on the left and right sides of the movable block; the first spring and the second spring are both sleeved on the sliding rod; one end of the first spring is connected to the first slider; the other end of the first spring is connected to the movable block; one end of the second spring is connected to the second slider; the other end of the second spring is connected to the movable block; the first spring and the second spring are in a stretched state; the left and right ends of the shielding cloth are respectively connected to two upright plates; the two ends of the shielding cloth are lower than the middle.

[0014] By adopting the above technical solution, the middle part of the shielding cloth, with the help of the elasticity of the first and second springs, keeps the reinforcing rod always in the middle of the two protective components. Then, the shielding cloth can prevent the pesticide from spreading upward. The pesticide can flow into the water collection chamber along the shielding cloth, which can protect the moving mechanism and prevent the pesticide from spreading upward, thus protecting the workers.

[0015] A further feature of this invention is that the spraying mechanism includes a support pipe, a water outlet pipe, and nozzles. The support pipe is vertically disposed in the middle of the inner side of the upright plate. One end of the water outlet pipe is connected to the support pipe, and the other end of the water outlet pipe is connected to the first water pump. Multiple nozzles are provided and are evenly installed on the support pipe from top to bottom.

[0016] By adopting the above technical solution, the nozzle is supported by a support pipe to spray the plants evenly on both sides.

[0017] A further feature of this invention is that a water level sensor is provided in the water collection tank, and a control panel is provided on the support plate. The first water pump, the second water pump, the water level sensor, the rotating motor, and the telescopic motor are all electrically connected to the control panel.

[0018] By adopting the above technical solution, the control panel controls the various electronic components to work together.

[0019] In summary, this utility model has the following beneficial effects:

[0020] Firstly, the protective components in this utility model are placed on both sides of the plant, and the shielding cloth is placed on the top of the plant to prevent the pesticide from spreading to the sides and top. The pesticide on the protective components and the shielding cloth is collected in the water collection chamber and then recycled, thus avoiding the waste of pesticides and reducing environmental pollution.

[0021] Secondly, the protective component in this utility model can be adjusted in position by a telescopic motor, allowing the lower end of the protective component to rotate inward, forming a trapezoid that is larger at the top and smaller at the bottom, which can better fit the plant and further prevent the spread of the pesticide solution.

[0022] Thirdly, the shielding cloth in this utility model, through the elasticity of the first spring and the second spring, keeps the middle part of the shielding cloth between the two protective components at all times, ensuring that the shielding cloth can effectively block the light.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Example: A pesticide application device for preventing potato diseases and pests, such as... Figures 1 to 4 As shown, the system includes a support plate 1, a moving mechanism 2 at the lower end of the support plate 1, and protective components 3 at both ends of the moving mechanism 2. The moving mechanism 2 can drive the two protective components 3 to move towards or away from each other to accommodate plants of different widths. A spraying mechanism 4 is located inside the protective components 3. A liquid storage tank 5 is located at the upper end of the support plate 1, and a first water pump 6 is installed inside the liquid storage tank 5. The spraying mechanism 4 is connected to the first water pump 6. The liquid storage tank 5 is used to store the prepared pesticide, which is then drawn up by the first water pump 6 and sprayed onto the plants by the spraying mechanism 4. A shielding cloth 7 is provided between the two protective components 3. The shielding cloth 7 is located above the spraying mechanism 4. The shielding cloth 7 mainly prevents the pesticide from spreading upwards, while the protective components 3 prevent the pesticide from spreading to the sides.

[0033] Of course, this device needs to be moved along with each row of potatoes during use. It can be equipped with wheels and handles for manual pushing, or it can be installed on a tractor for automated operation.

[0034] The protective component 3 includes a vertical plate 31, a base plate 32, an inlet pipe 33, a second water pump 34, a filter screen 35, and a baffle 36. The upper end of the vertical plate 31 is connected to the moving mechanism 2, serving as a shield. When the liquid comes into contact with the vertical plate 31, it adheres to it, collects as droplets, and flows downwards. The base plate 32 is connected to the inner side of the lower end of the vertical plate 31 and is L-shaped. The baffle 36 is located at both the front and rear ends of the vertical plate 31 and the base plate 32, extending to the inner sides of the vertical plate 31 and the base plate 32. 32. The baffle 36 and the upright plate 31 form a water collection cavity 37 with an open top. The medicine flows into the water collection cavity 37. A water collection trough 38 is provided at the bottom of the water collection cavity 37. The lower end of the water collection trough 38 is connected to one end of the liquid inlet pipe 33. The filter screen 35 is provided at the open end of the water collection trough 38. The medicine is collected in the water collection trough 38 and filtered by the filter screen 35. The other end of the liquid inlet pipe 33 is connected to the second water pump 34. The second water pump 34 is connected to the storage tank 5. Finally, the medicine is pumped back into the storage tank 5 by the second water pump 34 for recycling.

[0035] To make the protective component 3 close to the plant, the upper end of the upright plate 31 is rotatably connected to the moving mechanism 2. The inner side of the upright plate 31 is rotatably connected to the telescopic motor 8, and the other end of the telescopic motor 8 is rotatably connected to the moving mechanism 2. The telescopic motor 8 pushes the upright plate 31 to rotate, so that the upright plate 31 rotates inward to form a shape that is larger at the top and smaller at the bottom, in order to adapt to the potato plant. Of course, it can also be the plant of other plants.

[0036] The moving mechanism 2 includes a bidirectional lead screw 21, a first slider 22, a second slider 23, and a rotary motor 24. The lower end of the support plate 1 has a left-right oriented, open-ended groove 11. The bidirectional lead screw 21 is located within the groove 11, with one end rotatably connected to the support plate 1 and the other end connected to the rotary motor 24, which is located within the support plate 1. The first slider 22 and the second slider 23 are respectively connected to the left and right ends of the bidirectional lead screw 21, both threadedly connected to the lead screw 21. The first slider 22 and the second slider 23 are slidably connected to the groove 11. Two telescopic motors 8 are rotatably connected to the first slider 22 and the second slider 23, respectively. By rotating the bidirectional lead screw 21 via the rotary motor 24, the first slider 22 and the second slider 23 slide towards or away from each other, adjusting the distance between the two protective components 3 to accommodate plants of different widths.

[0037] The shielding cloth 7 has a front-to-back reinforcing rod 71 in the middle, and a movable block 72 is connected to the upper middle of the reinforcing rod 71. The slide groove 11 has a left-to-right sliding rod 73. The sliding rod 73 is slidably engaged with the first slider 22 and the second slider 23. The movable block 72 is slidably engaged with the sliding rod 73 and can slide left and right. The left and right sides of the movable block 72 are respectively provided with a first spring 74 and a second spring 75. The first spring 74 and the second spring 75 are both sleeved on the sliding rod 73. One end of the first spring 74 is connected to the first slider 22 and the other end of the first spring 74 is connected to the movable block 72. One end of the second spring 75 is connected to the second slider 23 and the other end of the second spring 75 is connected to the movable block 72. The first spring 74 and the second spring 75 are in a stretched state. The left and right ends of the shielding cloth 7 are respectively connected to two upright plates 31. The two ends of the shielding cloth 7 are lower than the middle. Due to the elasticity of the first spring 74 and the second spring 75, the movable block 72 can always remain in the middle of the two protective components 3, regardless of the position of the protective components 3, and provides good support for the shielding cloth 7. Of course, when the two protective components 3 are too close, the sides of the shielding cloth 7 will droop. As long as it does not affect the shielding effect, the collection effect will be poor. If necessary, an elastic shielding cloth 7 can be used, which can deform with the movement of the protective components 3.

[0038] The spraying mechanism 4 includes a support pipe 41, a water outlet pipe 42, and nozzles 43. The support pipe 41 is vertically installed in the middle of the inner side of the upright plate 31. One end of the water outlet pipe 42 is connected to the support pipe 41, and the other end of the water outlet pipe 42 is connected to the first water pump 6. Multiple nozzles 43 are evenly installed on the support pipe 41 from top to bottom. During use, the nozzles 43 atomize the pesticide solution evenly, allowing it to adhere better to the plants.

[0039] A water level sensor 9 is installed in the water collection tank 38. The water level sensor 9 detects the amount of medicine in the water collection tank 38, and the second water pump 34 is activated when a certain amount is reached. A control panel 10 is installed on the support plate 1. The first water pump 6, the second water pump 34, the water level sensor 9, the rotary motor 24, and the telescopic motor 8 are all electrically connected to the control panel 10. The control panel 10 can control the coordinated operation of various electronic components.

[0040] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
