Description

Technical Field

[0001] This invention relates to the field of vegetable planting technology, specifically to a spraying device for the prevention and control of vegetable diseases and pests. Background Technology

[0002] If vegetable diseases and pests are not controlled in time, they can cause stunted growth, sharp reductions in yield, and even rot and deformities by eating leaves, sucking sap, and spreading pathogens, seriously affecting the quality of vegetables. Spraying pesticides, as a fast and effective control method, can kill or inhibit the spread of diseases and pests in a timely manner, reduce their continuous damage to vegetables, ensure normal growth and development of vegetables, and thus stabilize yield and improve quality.

[0003] The Chinese patent publication number is CN115500335B, which discloses an extended nozzle mechanism for a pesticide sprayer for pest and disease control. The invention relates to the field of vegetable planting technology. The connecting pipe is connected to the water outlet of the sprayer. The extension mechanism is located above the connecting pipe and connected to the connecting pipe. The spraying mechanism is located below the extension mechanism and connected to the extension mechanism. The support mechanism is connected to the extension mechanism. This invention solves the problem of repeatedly moving the extension spray bar, which is time-consuming and laborious, and the extension spray bar is not easily deformed or broken.

[0004] The existing technology essentially involves manually adjusting the position of the sprayer according to demand, but the work efficiency is low in actual operation. In addition, the spraying equipment not only needs to be adjusted in length, but also needs to be adjusted in height and angle according to the height of the vegetables and the layout of the planting area. The existing technology also requires workers to manually operate and align it, which is time-consuming and labor-intensive, cannot meet the needs of large-scale vegetable planting, and has poor economic benefits.

[0005] In summary, the present invention provides a spraying device for the prevention and control of vegetable diseases and pests to solve the above problems. Summary of the Invention

[0006] This invention provides a spraying device for the prevention and control of vegetable diseases and pests, which solves the problems of low work efficiency and poor economic benefits in the prior art through intelligent multi-directional adjustment design.

[0007] The specific technical solution of this invention is as follows:

[0008] A spraying device for controlling vegetable diseases and pests includes a base, a medicine tank on top of the base, a spray pump on the side of the medicine tank, a bracket on the side of the spray pump, a curved plate fixedly connected to the top of the bracket, a first servo motor on top of the curved plate, a steering column fixedly connected to the output end of the first servo motor, a sliding column sleeved on the outer side of the steering column, a mounting block fixedly connected to the top of the sliding column, a side plate fixedly connected above the mounting block, an outer adjusting cylinder fixedly connected to one side of the side plate, and an inner adjusting cylinder on the inner side of the outer adjusting cylinder. An arc-shaped guide rail is provided on the outer side, and a mounting base is fixedly connected to the bottom of the arc-shaped guide rail. A sprayer is provided at the bottom of the mounting base, and a second servo motor is provided at the top of the mounting base. A rotating plate is fixedly connected to the output end of the second servo motor. An adjusting column is fixedly connected to the side of the rotating plate away from the second servo motor. A sliding block is fixedly connected to the side of the adjusting column. The sliding block is slidably connected to the arc-shaped guide rail. An outer adjusting groove is provided on the side of the outer adjusting cylinder, and the adjusting column is slidably connected to the outer adjusting groove. An inner adjusting groove is provided on the side of the inner adjusting cylinder, and the adjusting column is slidably connected to the inner adjusting groove.

[0009] In this invention, the base supports the overall structure and can be installed on an unmanned vehicle for automatic spraying; the medicine tank stores pesticides for common pest and disease control; the spray pump can be an existing diaphragm spray pump, which uses a rubber diaphragm to isolate the liquid pesticide from the moving parts of the pump body, resulting in leak-free operation, strong corrosion resistance, good self-priming ability, stable pressure, and tolerance to small amounts of impurities in the liquid pesticide, making it less prone to clogging; the spray pump provides stable pressure to draw the pesticide from the medicine tank and deliver it to the sprayer; the bracket mounts the various components at a preset height to adapt to actual spraying needs; the first servo motor and steering column adjust the direction of the device; the sliding column adjusts the height of the device; and the mounting block limits and guides the liquid outlet pipe to prevent it from tangling.

[0010] In this invention, the outer and inner adjusting cylinders are a length adjustment structure that works in conjunction with each other, designed specifically for the patterns of vegetable planting. Generally, vegetables are planted at fixed intervals, while existing length adjustment structures often adjust in stages, i.e., the first section moves to the corresponding position first, and after confirmation, the second section moves, resulting in low work efficiency. However, the structural design of the outer and inner adjusting cylinders allows for simultaneous extension or contraction to both sides. With multiple sets of outer and inner adjusting cylinders working together, the interval between multiple sprayers can be quickly changed, and when multiple servo motors run synchronously, the interval between different sprayers can remain consistent, thereby quickly adapting to changes in vegetable planting intervals and improving work efficiency.

[0011] In this invention, an arc-shaped guide rail is used to limit the direction of movement of the sliding block; the mounting base is used to limit the inner adjusting cylinder and prevent it from rotating; the adjusting column passes through both the outer and inner adjusting grooves. When the second servo motor is started, power is transmitted to the adjusting column through the rotating plate, causing the sliding block to slide along the arc-shaped guide rail. The adjusting column simultaneously slides along both the outer and inner adjusting grooves. Since the outer and inner adjusting grooves have the same shape but opposite directions, and one side of the outer adjusting cylinder is fixed, the adjusting column essentially slides along the outer adjusting groove, driving the inner adjusting cylinder to move synchronously through the inner adjusting groove. The movement of the adjusting column also drives the mounting base to move, thereby moving the sprayer. Essentially, this allows the sprayer to move linearly along the direction of the outer adjusting cylinder, achieving length adjustment. Furthermore, for multiple sets of second servo motors, synchronous operation can simultaneously adjust the spacing of multiple sprayers, or they can operate separately according to actual needs, thus adapting to actual planting scenarios such as mixed vegetable planting, irregular spacing, and complex terrain, further expanding the applicability of the device.

[0012] In this invention, the sprayer can use nozzles commonly found in the prior art, which can be used individually or in combination with multiple nozzles.

[0013] In a preferred embodiment, a suction pipe is detachably connected between the medicine tank and the spray pump, a discharge pipe is detachably connected to the side of the spray pump away from the suction pipe, and one side of the sprayer is detachably connected to the discharge pipe.

[0014] In this invention, two or more medicine tanks can be installed simultaneously, and they can be connected to the spray pump through several T-joints and suction pipes; the discharge pipe can also be equipped with multiple branch pipes to further improve the density and efficiency of spraying.

[0015] In a preferred embodiment, a third servo motor is provided on the side of the bending plate, a forked plate is fixedly connected to the output end of the third servo motor, a roller is rotatably connected to one side of the forked plate, a transmission component is provided on the side of the roller, and the transmission component is fixedly connected to the sliding column.

[0016] In this invention, the transmission component is closely fitted to both sides of the roller. When the third servo motor is started, the forked plate rotates, the roller rolls along the transmission component and drives the transmission component to rise or fall, thereby driving the sliding column to slide along the steering column, and then using the mounting block to change the height of the device. The dimensions of the forked plate, roller and transmission component are designed according to actual needs. The greater the range of height adjustment, the larger the overall size.

[0017] In a preferred embodiment, a first limiting post is fixedly connected to one side of the mounting base, and a first sliding groove is provided on the side of the outer adjusting cylinder near the first limiting post, wherein the first limiting post is slidably connected to the first sliding groove.

[0018] In this invention, the first limiting post is used to restrict the direction of movement of the mounting base.

[0019] In a preferred embodiment, a second limiting post is fixedly connected to the side of the mounting base away from the first limiting post, and a second sliding groove is provided on the side of the inner adjusting cylinder near the second limiting post, with the second limiting post and the second sliding groove being slidably connected.

[0020] In this invention, the second limiting post is used to limit the direction of movement of the mounting base and prevent the inner adjusting cylinder from rotating.

[0021] In a preferred embodiment, an extension tube is detachably connected to the side of the sprayer away from the outlet pipe, and a fixing block is detachably connected to the side of the extension tube away from the sprayer.

[0022] In this invention, the extension tube and the fixing block are used to connect to the next set of sprayers, expanding the number of nozzles deployed simultaneously by the device.

[0023] In a preferred embodiment, an extension plate is fixedly connected above the fixing block, and one side of the extension plate is fixedly connected to the inner adjusting cylinder.

[0024] In this invention, the extension plate is used to connect to the next set of external adjustment cylinders, and the expansion device can adjust the number of nozzles.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. This invention achieves synchronous and rapid adjustment of the sprayer spacing and intelligent control of the device height and direction through the cooperation of the outer and inner adjusting cylinders. The outer and inner adjusting cylinders can extend and retract to both sides simultaneously, which can quickly adapt to the vegetable planting interval while ensuring that the spacing of multiple sprayers is consistent, reducing the cost of manual intervention, improving the efficiency of spraying, and fully meeting the operational needs of large-scale vegetable planting.

[0027] 2. This invention can adapt to a single vegetable planting mode with regular intervals, and can also cope with diverse scenarios such as mixed vegetable planting, irregular intervals, and complex terrain. It can also easily expand the number of nozzles deployed and increase the spraying density, and is easy to maintain and replace, making it practical and economical. Attached Figure Description

[0039] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0040] like Figure 1-10As shown, this invention provides a spraying device for controlling vegetable diseases and pests, including a base 1, a medicine tank 2 above the base 1, a spray pump 3 on the side of the medicine tank 2, a bracket 4 on the side of the spray pump 3, a curved plate 5 fixedly connected to the top of the bracket 4, a first servo motor 6 above the curved plate 5, a steering column 7 fixedly connected to the output end of the first servo motor 6, a sliding column 8 sleeved on the outer side of the steering column 7, a mounting block 9 fixedly connected to the top of the sliding column 8, a side plate 10 fixedly connected above the mounting block 9, an outer adjusting cylinder 11 fixedly connected to one side of the side plate 10, an inner adjusting cylinder 12 on the inner side of the outer adjusting cylinder 11, and an arc-shaped guide rail 1 on the outer side of the outer adjusting cylinder 11. 3. A mounting base 14 is fixedly connected to the bottom of the arc-shaped guide rail 13. A sprayer 15 is provided at the bottom of the mounting base 14. A second servo motor 16 is provided at the top of the mounting base 14. A rotating plate 17 is fixedly connected to the output end of the second servo motor 16. An adjusting column 18 is fixedly connected to the side of the rotating plate 17 away from the second servo motor 16. A sliding block 19 is fixedly connected to the side of the adjusting column 18. The sliding block 19 is slidably connected to the arc-shaped guide rail 13. An outer adjusting groove 1101 is provided on the side of the outer adjusting cylinder 11. The adjusting column 18 is slidably connected to the outer adjusting groove 1101. An inner adjusting groove 1201 is provided on the side of the inner adjusting cylinder 12. The adjusting column 18 is slidably connected to the inner adjusting groove 1201.

[0041] A suction pipe 301 is detachably connected between the medicine tank 2 and the spray pump 3. A discharge pipe 302 is detachably connected to the side of the spray pump 3 away from the suction pipe 301. One side of the sprayer 15 is detachably connected to the discharge pipe 302.

[0042] A third servo motor 20 is provided on the side of the bending plate 5. A forked plate 21 is fixedly connected to the output end of the third servo motor 20. A roller 2101 is rotatably connected to one side of the forked plate 21. A transmission component 22 is provided on the side of the roller 2101. The transmission component 22 is fixedly connected to the sliding column 8.

[0043] A first limiting post 1401 is fixedly connected to one side of the mounting base 14, and a first sliding groove 1102 is provided on the side of the outer adjusting cylinder 11 near the first limiting post 1401. The first limiting post 1401 is slidably connected to the first sliding groove 1102.

[0044] The mounting base 14 is fixedly connected to the second limiting post 1402 on the side away from the first limiting post 1401. The inner adjusting cylinder 12 is provided with a second sliding groove 1202 on the side close to the second limiting post 1402. The second limiting post 1402 is slidably connected to the second sliding groove 1202.

[0045] An extension tube 303 is detachably connected to the side of the sprayer 15 away from the outlet tube 302, and a fixing block 23 is detachably connected to the side of the extension tube 303 away from the sprayer 15.

[0046] An extension plate 24 is fixedly connected above the fixed block 23, and one side of the extension plate 24 is fixedly connected to the inner adjusting cylinder 12.

[0047] The working principle of this invention is as follows: When the device is started, the pest control agent stored in the medicine tank 2 is sucked into the spray pump 3 through the suction pipe 301. The spray pump 3 generates stable pressure, pressurizes the agent and delivers it through the outlet pipe 302 to the sprayer 15 which is detachably connected to the outlet pipe 302. Finally, the sprayer 15 atomizes and sprays the agent to complete the basic spraying action.

[0048] After the third servo motor 20 starts, its output end drives the fork plate 21 to rotate, and the roller 2101 moves accordingly. Since the roller 2101 is in close contact with the transmission component 22, when the roller 2101 rolls along the transmission component 22, it will drive the transmission component 22 to rise or fall synchronously, thereby driving the sliding column 8 to slide axially along the steering column 7. The mounting block 9 moves with the sliding column 8, driving the side plate 10 and the subsequently connected external adjusting cylinder 11, sprayer 15 and other components to rise and fall synchronously, realizing the adjustment of the spraying height to adapt to the needs of vegetable planting at different heights and with different seedling conditions.

[0049] After the first servo motor 6 starts, the steering column 7 fixedly connected to its output end will rotate accordingly. The rotation of the steering column 7 will directly drive the sliding column 8 to rotate synchronously. The sliding column 8 drives the upper structure, such as the outer adjusting cylinder 11 and the sprayer 15, to rotate as a whole through the mounting block 9 and the side plate 10, thereby adjusting the spraying direction of the sprayer 15. This can achieve full coverage of vegetable areas with different planting layouts, such as areas blocked by greenhouse pillars or irregular open-field planting areas, and quickly adjust the spraying direction to avoid blind spots.

[0050] After the second servo motor 16 starts, its output drives the rotating plate 17 to rotate, and the adjusting column 18 generates power accordingly. The arc-shaped guide rail 13 restricts the movement direction of the sliding block 19, so that the adjusting column 18 can only move along the trajectory of the arc-shaped guide rail 13. At the same time, the adjusting column 18 also slides in cooperation with the outer adjusting groove 1101 and the inner adjusting groove 1201 respectively. Since the outer adjusting cylinder 11 is fixed to the mounting block 9 through the side plate 10, its position remains unchanged. The outer adjusting groove 1101 and the inner adjusting groove 1201 have the same shape but opposite directions. When the adjusting column 18 slides along the outer adjusting groove 1101, it will pass through the inner adjusting groove 1201. 201 drives the inner adjusting cylinder 12 to move synchronously; during this process, the first limiting post 1401 slides along the first sliding groove 1102, and the second limiting post 1402 slides along the second sliding groove 1202. The double limiting ensures the stable movement of the mounting base 14, thereby driving the bottom sprayer 15 to move linearly along the direction of the outer adjusting cylinder 11, realizing the adjustment of the spacing of the sprayers 15; the present invention enables multiple sets of sprayers 15 to extend and retract to both sides at the same time. For example, when the vegetable planting interval becomes larger, the present invention can make the spacing of all sprayers adjust synchronously, greatly improving work efficiency and adjustment accuracy, and adapting to the standardized planting interval of most vegetables.

[0051] Throughout the entire operation, different servo motors can operate independently or synchronously. For example, for mixed-crop vegetables, the spacing and height of the corresponding area sprayers 15 can be adjusted individually; for vegetables planted in contiguous areas, all motors can be started simultaneously to achieve rapid adaptation.
