Description

Technical Field

[0001] This utility model belongs to the technical field of spraying devices, and in particular relates to a track-type automatic spraying device for vegetable greenhouses. Background Technology

[0002] In modern facility agriculture, vegetable greenhouses create an excellent environment for improving crop yield and quality. However, the enclosed and humid interior of greenhouses makes them highly susceptible to pests and diseases. Therefore, regular and efficient pesticide spraying is crucial for ensuring the healthy growth of greenhouse vegetables. Currently, to replace inefficient, labor-intensive, and harmful manual spraying methods, various automated spraying devices have emerged on the market. Among them, track-mounted automatic spraying devices are widely used because they can move along a preset track within the greenhouse, enabling large-scale, automated spraying operations. These devices typically include a mobile trolley, a pesticide tank, a water pump, and a spray pipe mounted on the trolley, with multiple nozzles installed on the pipe.

[0003] According to publication number CN205040491U, the title is: "A Track-Type Automatic Sprayer for Greenhouse Pesticide Spraying," comprising a small air compressor, a stainless steel pesticide delivery pipe, an obstacle sensor, and a pesticide sorting and storage box. A housing is located below the small air compressor, and the pesticide sorting and storage box is located above the housing. The obstacle sensor is located on the side of the pesticide sorting and storage box. The stainless steel pesticide delivery pipe is located on the surface of the pesticide sorting and storage box, and a wireless electronic switch is located in the middle of the stainless steel pesticide delivery pipe. A central controller is located behind the small air compressor, and a signal processor is located above the central controller. A drive screw is located inside the housing, and a rotating nozzle is located below the housing.

[0004] The aforementioned patent describes a significant drawback of the track-mounted automatic spraying device: the height of its spray nozzle is typically fixed. In practical applications, the types of vegetables grown in greenhouses may differ, and even for the same type of vegetable, plant height varies significantly at different growth stages (e.g., seedling stage, growth stage, maturity stage). For example, the canopy height of low-growing leafy vegetables differs greatly from that of climbing fruiting crops. A fixed-height spray nozzle exhibits the following problems when dealing with crops of varying heights: poor spraying effect, and uneven spraying when the nozzle is positioned significantly higher than the low-growing crops. Utility Model Content

[0005] The purpose of this utility model is to provide a track-type automatic spraying device for vegetable greenhouses to solve the technical problem of the inability to adjust the spray nozzle mentioned in the background art.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: A track-type automatic spraying device for vegetable greenhouses includes a medicine tank, and multiple first spray pipes evenly distributed at the bottom of the medicine tank. The first spray pipes are hollow inside with openings at both ends. The top of the first spray pipes communicates with the inside of the medicine tank. A second spray pipe is coaxially arranged inside the first spray pipe, and a nozzle is fixed at the end of the second spray pipe. The second spray pipe can be extended and retracted by an adjustment mechanism between the first spray pipe and the second spray pipe.

[0007] Preferably, a drive box is provided above the medicine box, and a travel wheel is provided above the drive box. A support wheel is also fixed on the top of the drive box.

[0008] Preferably, a track is held between the two traveling wheels, and the track is fixedly connected to the steel frame of the inner roof of the greenhouse.

[0009] Preferably, the connecting plate and the top of the medicine tank are provided with a medicine inlet facing downwards, through which the medicine liquid can be added into the medicine tank. At the same time, a pressure pump is fixed on the top of the connecting plate, and the pressure pump continuously pressurizes the inside of the medicine tank during operation.

[0010] Preferably, a charging frame is fixed to one end of the bottom surface of the track, a charging base is fixed to one end of the charging frame, and a battery is fixed inside the drive box.

[0011] Preferably, a charging connector is also fixed at the bottom of the drive box, wherein the charging connector is electrically connected to the battery.

[0012] Preferably, the adjustment mechanism is composed of a hand-tightening screw, and a first threaded hole is provided inward on the outer circumferential surface of the first spray pipe, wherein the external thread of the hand-tightening screw can be threadedly connected to the internal thread of the first threaded hole.

[0013] Preferably, the adjustment mechanism consists of a brake motor and a threaded rod fixedly connected below the output end of the brake motor. A fixing rod is fixed on the bottom surface of the medicine box, and the end of the fixing rod is fixedly connected to the brake motor. The brake motor can be limited by the fixing rod.

[0016] The automatic track-type spraying device for vegetable greenhouses of this utility model has the following advantages: This is a track-mounted automatic pesticide spraying device for vegetable greenhouses. When pesticide spraying is needed inside the greenhouse, the traveling wheels rotate continuously, causing the pesticide tank to move along with them. A pressure pump on the tank continuously pressurizes the tank, forcing the pesticide to be sprayed from the nozzles. The stable movement of the traveling wheels improves the uniformity of the spraying. When the height of the second spray pipe needs adjustment, the hand screw can be turned until its end no longer contacts the second spray pipe, allowing for vertical adjustment. After height adjustment, the hand screw can be turned in the opposite direction to fix the second spray pipe in place, facilitating spraying in different areas inside the greenhouse.

[0020] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a track-type automatic spraying device for vegetable greenhouses.

[0021] like Figures 1-4 As shown, the first embodiment of this application is illustrated. Its main technical solution includes a track 1, which can be connected to the steel frame of the inner roof of the greenhouse, so that the track 1 can be suspended in the air. At the same time, the track 1 is clamped on both sides for walking. The drive box 12 is located below the walking wheel 11, and the rotation of the walking wheel 11 is driven by a motor fixed inside the drive box 12. The output shaft of the motor is fixedly connected to the center of the walking wheel 11.

[0022] A support wheel 16 is also fixed on the top of the drive box 12. The outer circumferential surface of the support wheel 16 abuts against the two sides of the bottom surface of the I-beam. There are four support wheels 16, which are symmetrically distributed in a rectangle to provide stability for travel.

[0023] A connecting plate 2 is fixed at the bottom of the drive box 12, and a medicine tank 21 is fixed on the bottom surface of the connecting plate 2. The medicine tank 21 has a hollow structure inside, and a medicine inlet 23 is opened downward at the top of the connecting plate 2 and the medicine tank 21. The medicine can be added into the medicine tank 21 through the medicine inlet 23. At the same time, a pressure pump 22 is fixed at the top of the connecting plate 2. The pressure pump 22 continuously pressurizes the inside of the medicine tank 21 during operation.

[0024] Multiple first spray pipes 211 are evenly distributed at the bottom of the medicine tank 21. The first spray pipes 211 are hollow inside with openings at both ends. The top of the first spray pipes 211 is connected to the inside of the medicine tank 21. A second spray pipe 212 is coaxially placed inside the first spray pipes 211, and a nozzle 213 is fixed at the end of the second spray pipe 212. Therefore, when the medicine needs to be sprayed inside the greenhouse, the traveling wheel 11 can rotate continuously. As the traveling wheel 11 rotates, the medicine tank 21 can move along with it. Since the pressure pump 22 on the medicine tank 21 continuously pressurizes the inside of the medicine tank 21, the pressure inside the medicine tank 21 can then spray the medicine from the nozzle 213. Furthermore, the uniformity of spraying is improved when the traveling wheel 11 moves forward steadily.

[0025] The second spray pipe 212 can be extended or retracted by an adjustment mechanism between the first spray pipe 211 and the second spray pipe 212.

[0026] The adjustment mechanism consists of a hand-tightening screw 215. A first threaded hole 214 is provided on the outer circumference of the first spray pipe 211. The external thread of the hand-tightening screw 215 can be threadedly connected to the internal thread of the first threaded hole 214. Therefore, when the height of the second spray pipe 212 needs to be adjusted, the hand-tightening screw 215 can be rotated so that the end of the hand-tightening screw 215 no longer touches the second spray pipe 212. Then, the second spray pipe 212 can be adjusted up and down. After the height adjustment is completed, the hand-tightening screw 215 can be rotated in the opposite direction to fix the second spray pipe 212, which is convenient for spraying different areas inside the greenhouse.

[0027] like Figure 5 As shown, a charging frame 13 is fixed at one end of the bottom surface of the track 1, and a charging base 131 is fixed at one end of the charging frame 13. A battery 15 is also fixed inside the drive box 12. The battery 15 can provide power to the drive box 12 and the spraying device. A charging connector 14 is also fixed at the bottom of the drive box 12. The charging connector 14 is electrically connected to the battery 15. Therefore, when the battery 15 is low on power and returns to the initial position, the charging connector 14 is connected to the charging base 131, and then the battery 15 is charged.

[0028] like Figures 6-8 As shown, the second embodiment of this application is illustrated. Although it maintains the same core design concept as the first embodiment, the adjustment mechanism has been improved. The adjustment mechanism consists of a brake motor 31 and a threaded rod 32 fixedly connected below the output end of the brake motor 31. A fixing rod 3 is fixed on the bottom surface of the medicine box 21, and the end of the fixing rod 3 is fixedly connected to the brake motor 31. The brake motor 31 can be limited by the fixing rod 3.

[0029] A limiting block 4 is fixed to the inner ring wall of the bottom opening of the first spray pipe 211, and a limiting groove 5 is opened on the outer circumferential surface of the second spray pipe 212, with one end of the limiting block 4 extending into the limiting groove 5.

[0030] An extension plate 51 is fixed to the outer circumference of the second spray pipe 212. The top surface of the extension plate 51 has a second threaded hole 52 extending downwards. The second threaded hole 52 is threadedly connected to the threaded rod 32. Therefore, when the height of the second spray pipe 212 needs to be adjusted, the brake motor 31 drives the threaded rod 32. The threaded rod 32 is threadedly connected to the second threaded hole 52, which can push the extension and retraction of the second spray pipe 212, thereby adjusting the height of the second spray pipe 212. Furthermore, the brake motor 31, the threaded rod 32, and the second threaded hole 52 have a certain self-locking property, which can prevent the second spray pipe 212 from loosening after the height is adjusted.

[0031] The working principle of a track-type automatic pesticide spraying device for vegetable greenhouses: When pesticide spraying is required inside the greenhouse, the traveling wheel 11 rotates continuously, causing the pesticide tank 21 to move along with it. The pressure pump 22 on the pesticide tank 21 continuously pressurizes the inside of the tank, which then forces the pesticide to be sprayed from the nozzle 213. The stable forward movement of the traveling wheel 11 improves the uniformity of spraying. When the height of the second spray pipe 212 needs adjustment, the hand screw 215 can be turned so that its end no longer contacts the second spray pipe 212, allowing for vertical adjustment. After height adjustment, the hand screw 215 is turned in the opposite direction to fix the second spray pipe 212, facilitating spraying in different areas inside the greenhouse.
