Description

Technical Field

[0001] The utility model relates to the technical field of agricultural greenhouses, and more specifically, to an agricultural greenhouse spraying device. Background Art

[0002] In the prior art, for example, Chinese utility model patent No. CN210275633U discloses a pesticide spraying device specifically for greenhouses. The device uses an electric motor to drive the base to move, thereby driving the movement of the spray pipe and water tank. Because the motor increases the driving force, the device moves at a uniform speed. Furthermore, the device sprays the pesticide evenly through the operation of a water pump, thereby improving both work efficiency and insecticide control effectiveness. However, the aforementioned technical solution still has the following drawbacks: Because the leaves of crop plants are generally large, during the spraying process, the vast majority of the pesticide solution lands on the leaf surface, leaving only a small portion of the solution on the plant stems or the back of the leaves. This, in turn, prevents the effective removal of pests on the plant stems or the back of the leaves. Utility Model Content

[0003] In order to overcome the defects of the existing technology, the utility model proposes an agricultural greenhouse spraying device. Through the provided toggle part, it can drive the plants to shake while spraying pesticides, thereby increasing the gaps between the leaves.

[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0019] like Figure 1-3As shown, an agricultural greenhouse spraying device is provided in the embodiment, including a greenhouse frame 1, a moving mechanism 2 and a spraying mechanism 3. The greenhouse frame 1 is slidably connected to the moving mechanism 2, and the spraying mechanism 3 is connected to the moving mechanism 2. The spraying mechanism 3 includes an electric push rod 31, a mounting seat 32, a retractable bracket 33, a retractable hose 34, an atomizing nozzle 35 and a toggle member 36. The fixed end of the electric push rod 31 is connected to the moving mechanism 2, and the output end of the electric push rod 31 is connected to the mounting seat 32. A retractable bracket 33 is provided at the bottom of the mounting seat 32, and the bottom of the retractable bracket 33 is provided. A retractable hose 34 is disposed transversely on the frame 1, and one end of the retractable hose 34 is connected to the medicine storage box. Two or more atomizing nozzles 35 are evenly arranged on the retractable hose 34. A toggle member 36 is also provided on the retractable bracket 33. The toggle member 36 includes a support plate 361, a motor 362, a rotating block 363, and a rubber rod 364. One end of the support plate 361 is rotatably connected to the retractable bracket 33. The support plate 361 is fixed with a motor 362. The power output shaft of the motor 362 is connected to a rotating block 363. The circumferential surface of the rotating block 363 is provided with a rubber rod 364. In this embodiment, the moving mechanism 2 can slide on the greenhouse frame 1, thereby driving the spraying mechanism 3 to move synchronously to achieve continuous and uniform spraying of crop plants in various locations within the greenhouse, which can not only improve the spraying efficiency and effect, but also reduce labor intensity. Among them, the electric push rod 31 is a retractable structure, which can drive the mounting seat 32 and the atomizing nozzle 35 to move up and down to adjust the height of the atomizing nozzle 35, thereby adapting to the spraying operation of plants at different heights, and the nozzle of the atomizing nozzle 35 is arranged downward; the mounting seat 32 is arranged horizontally, and is used to install and support the retractable bracket 33. The retractable bracket 33 is a retractable structure, which can be unfolded when in use and can adjust the distance between two adjacent atomizing nozzles 35, thereby adapting to different crop row spacing requirements, and can be retracted when not in use to reduce the occupied space; the retractable hose 34 is a retractable corrugated tube, which can be extended synchronously with the extension of the retractable bracket 33. And it shortens synchronously with the contraction of the retractable bracket 33; the set atomizing nozzle 35 can atomize the pesticide and spray it out to make the spraying more uniform; because the leaves of the plant are usually large, during the spraying process, most of the atomized droplets will fall on the leaves, and only a small part of the medicine can fall on the stems or the back of the leaves, which will lead to the inability to effectively remove the pests on the stems and the back of the leaves, and the pest control effect is poor. Through the set toggle member 36, the plant can be driven to shake during the spraying process, and the distance between the leaves becomes larger due to the shaking. At this time, more atomized droplets can pass through the gaps between the leaves to reach the stems and the back of the leaves, so as to achieve better and more efficient pest control operations.Among them, the support plate 361 is a long strip structure, and by rotating the support plate 361, the position of the rubber rod 364 can be adjusted, and then when the retractable bracket 33 is opened, the rotating block 363 and the rubber rod 364 are both located in the row gap of the crop plants; the power output shaft of the motor 362 is arranged downward, and the motor 362 can drive the rubber rod 364 to rotate to move the plant stems, so that the leaves shake synchronously; the rubber rod 364 is made of rubber material and has a certain elasticity. Since the rubber rod 364 will also be subjected to reverse load when moving the plant stems, when the load is too large, the rubber rod 364 will undergo adaptive bending and deformation, thereby preventing the plant from falling over or being broken.

[0020] Specifically, the retractable bracket 33 includes a scissor unit 331, a first slider 332, a connecting block 333, and a fixing ring 335. Two or more scissor units 331 are evenly arranged in the horizontal direction. Each end of the scissor unit 331 is connected to the first slider 332. A connecting block 333 is provided between adjacent scissor units 331. Slide grooves 334 are provided on both sides of the connecting block 333, and the first slider 332 is slidably connected to the slide grooves 334. A fixing ring 335 is provided at the bottom of the connecting block 333, and the retractable hose 34 is mounted on the fixing ring 335. In this embodiment, the scissor units 331 are composed of two connecting rods and form an X-shaped structure. The first slider 332 is hingedly connected to each of the four ends of the scissor unit 331. The connecting block 333 is an elongated structure, with a chute 334 running along its length. The two first sliders 332 on the side of the scissor unit 331 near the connecting block 333 slide into the same chute 334. There are an equal number of support plates 361 and a one-to-one correspondence between the connecting blocks 333. When the two connecting rods of the scissor unit 331 rotate relative to each other, they move the two connecting blocks 333 closer or further apart, thereby synchronously extending or contracting the telescopic hose 34. A fixing ring 335 buckles onto the telescopic hose 34, facilitating installation and removal.

[0021] Specifically, a pin 336 is fixed to the end of the connecting block 333, and the free end of the pin 336 is rotatably connected to the support plate 361. In this embodiment, the pin 336 allows the support plate 361 to rotate about the pin 336. When the retractable bracket 33 is in the retracted state, the support plate 361 rotates to a state where it coincides with the length of the connecting block 333. When the retractable bracket 33 is in the extended state, the support plate 361 rotates and positions the rotating block 363 to one side of the atomizing nozzle 35.

[0022] Specifically, an adjustment handle 337 is further provided on the connecting block 333. In this embodiment, the adjustment handle 337 is provided to facilitate pulling the connecting block 333 to adjust the spacing between adjacent connecting blocks 333.

[0023] Specifically, the mobile mechanism 2 includes a mobile base 21, a first motor 22, and a roller 23. The mobile base 21 is equipped with the first motor 22, which is a double-ended motor. The roller 23 is connected to the power output shaft of the first motor 22, and the roller 23 is configured to roll on the greenhouse frame 1. In this embodiment, the mobile base 21 is located in a gap within the greenhouse frame 1. The power output shaft of the first motor 22 is arranged horizontally, and the first motor 22 drives the roller 23 to move along the greenhouse frame 1, thereby driving the mobile base 21 to move synchronously. The roller 23 is provided with an annular groove on its circumferential surface.

[0024] Specifically, guide sleeves 24 are fixed on the front and rear sides of the movable seat 21, and the guide sleeves 24 are slidably connected to the greenhouse frame 1. In this embodiment, the guide sleeves 24 are used to auxiliary support the movable seat 21, and the guide sleeves 24 are sleeved on the greenhouse frame 1 to prevent the device from overturning.

[0025] Working principle: When in use, first open the retractable bracket 33, and control the distance between two adjacent atomizing nozzles 35 according to the row spacing of the crop plants, so that the nozzle of the atomizing nozzle 35 is aligned with the top of the plant, and at the same time rotate the support plate 361 so that the rotating block 363 is located between the rows of the plant and ensures that the end of the rubber rod 364 can hit the plant stem. Then start the first motor 22, the first motor 22 drives the roller 23 to roll on the greenhouse frame 1, thereby moving the movable seat 21, and the movement of the movable seat 21 drives the atomizing nozzle 35 to move synchronously, and the atomizing nozzle 35 sprays the liquid medicine onto the plant, and at the same time the motor 362 drives the rotating block 363 to rotate, and the rotation of the rotating block 363 drives the rubber rod 364 to rotate synchronously to move the plant stem, thereby causing the plant leaves to shake to expand the gap between the leaves, so that more drug droplets can pass through the gap and fall on the back of the stem and plant leaves, thereby improving the insecticide effect.
