Description

Technical Field

[0001] This utility model relates to the field of agricultural automation equipment, specifically a track-based greenhouse inspection and spraying device. Background Technology

[0002] In the application of agricultural automation equipment, greenhouse inspection and spraying is an important part of greenhouse environmental management. When carrying out greenhouse agricultural production, the coordinated operation of greenhouse track inspection and precise variable-rate spraying can play an excellent role in protecting crops and promoting production in the greenhouse.

[0003] In existing technologies, when dealing with the two operations of inspection and spraying in greenhouses, inspection and spraying are usually separated. Inspection equipment is used to inspect the crops in the greenhouse and mark the corresponding locations on an electronic map. During spraying, there are normal spraying operations and targeted spraying operations. At this time, existing technologies use manual screening to perform different spraying operations on different areas.

[0004] Existing technologies can effectively monitor and spray crops in greenhouses, but they suffer from serious efficiency problems. Furthermore, because existing technologies rely too heavily on the positioning markers of electronic maps, when there are systematic errors in the electronic map markers, such as when there is a delay in the transmission signal, there will be problems with the targeted spraying location. This not only fails to solve the problem of precise variable application of pesticides, but also leads to over-application of pesticides to some crops, thereby causing damage.

[0005] Therefore, how to effectively balance crop inspection and spraying operations in greenhouses and reduce errors in the process has become an urgent problem to be solved in the field of agricultural automation equipment. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies that separate inspection and spraying during greenhouse inspections, leading to inconsistencies in spraying positions during greenhouse environmental maintenance. This invention provides a track-based greenhouse inspection and spraying device that uses inspection probes to screen locations requiring precise variable-rate pesticide application during inspections, records and verifies these locations using a label scanner, and then applies precise variable-rate pesticides to the designated locations via a spraying mechanism. This allows for simultaneous inspection and spraying of crops within the greenhouse while avoiding positional errors, thereby improving the efficiency of greenhouse environmental management.

[0007] The objective of this utility model is mainly achieved through the following technical solutions:

[0008] The track-based greenhouse inspection and spraying device includes a mounting track on which the main body of the device is slidably connected. Several spraying mechanisms are provided on the side of the main body of the device, and the spraying mechanisms are used to spray liquid.

[0009] A first set of rollers is fixed on the main body of the device. The first set of rollers is embedded in the mounting track and can slide back and forth along the mounting track.

[0010] The first roller assembly is equipped with a label scanner, and the mounting track is provided with a number of location labels. The label scanner is used to scan and record the location labels.

[0011] The device is equipped with an inspection probe at the bottom of its main body.

[0012] Currently, in the process of managing the internal environment of greenhouses, greenhouse track inspection and precision variable spraying are two important operations. When inspecting the greenhouse track, it is necessary to observe the crops and record the locations where precision variable spraying is required. Existing technology usually uses electronic map marking to record the location. First, the location of the inspection equipment is found on the electronic map and then marked. However, due to the data transmission process, there is a risk of delay, which may result in the wrong location being recorded. This will also lead to the problem of spraying the wrong location during subsequent spraying operations.

[0013] Existing technologies also use mechanical marking to mark the spraying location, such as spray painting or placing beacons. This method of operation may have a greater possibility of error, thus making the error of precise variable application even greater.

[0014] In this invention, the inspection probe performs the functions of inspecting crops and marking the location of problematic crops as in the prior art. At the same time, this invention also records the specific position of the main body of the device on the track by setting tags on the track and mounting a tag scanner on the first roller group. Thus, the location of the main body of the device can be identified according to the changes of the tags.

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0043] Example:

[0044] like Figures 1-6 As shown, this embodiment relates to a track-based greenhouse inspection and spraying device, including a mounting track 1, on which a device body 6 is slidably connected. The side of the device body 6 is provided with a plurality of spraying mechanisms 5, which are used to spray liquid.

[0045] A first roller assembly 2 is fixed on the main body 6 of the device. The first roller assembly 2 is embedded in the mounting track 1 and can slide back and forth along the mounting track 1.

[0046] The first roller group 2 is equipped with a label scanner 26, and the mounting track 1 is provided with a number of position labels. The label scanner 26 is used to scan and record the position labels.

[0047] The bottom of the main body 6 of the device is equipped with an inspection probe 41.

[0048] In practical application, the main body 6 of the device supports the spraying mechanism 5. When the first roller group 2 reciprocates within the mounting track 1, the main body 6, carrying the spraying mechanism 5, reciprocates along the mounting track 1. The inspection probe 41 at the bottom of the main body 6 inspects the crops according to existing technology and determines the location requiring precise variable-rate pesticide application. This location is recorded using an electronic map. The label scanner 26 continuously scans the location labels on the mounting track 1. When the inspection probe 41 records the precise variable-rate pesticide application location, the label scanner 26 immediately records the current location label. Thus, when the location record of the label scanner 26 matches the location record of the inspection probe 41, the exact location of the spraying liquid is determined.

[0049] Once the spraying location is determined, the spraying mechanism 5 is activated to spray the corresponding location, thereby completing the precise variable-rate application of pesticides to crops.

[0050] In this process, this embodiment improves the accuracy of location marking through the combined action of location tags and inspection probes 41, and completes real-time precise variable pesticide application through the spraying mechanism 5 set on the main body of the device 6. While ensuring the accuracy of precise variable pesticide application, it avoids the risk of location changes caused by device switching, such as the spread of pests and diseases, or relocation.

[0051] In this embodiment, the first roller group 2 is embedded in the mounting track 1 to mount the main body 6 of the device. By setting the spraying mechanism 5 on the side of the main body 6 of the device, a wider coverage of the spraying position is achieved, thereby ensuring the operation of precise variable drug application.

[0052] In this embodiment, the label scanner 26 adopts a model that is capable of continuous scanning and identification in the prior art.

[0053] Furthermore, a second roller group 7 is also fixed on the main body 6 of the device. The second roller group 7 is embedded in the mounting track 1 and can slide back and forth along the mounting track 1.

[0054] The second roller assembly 7 is equipped with a spare label scanner 26, which is used to scan and record the location label;

[0055] There is a gap between the second roller group 7 and the first roller group 2, and the structure of the second roller group 7 is the same as that of the first roller group 2.

[0056] In this embodiment, the mounting of the second roller group 7 effectively ensures the stability of the device body 6 during reciprocating sliding, thereby ensuring the stability of the device operation. The second roller group 7 is equipped with a backup label scanner 26, which can synchronously record the position of the label scanner 26, effectively increasing the security of position recording. Furthermore, by maintaining a gap with the first roller group 2, it can provide feedback on the intermediate position of the first roller group 2 and the second roller group 7. When the device body 6 is large, this method can obtain more accurate feedback on the device's position. The backup label scanner 26 also effectively avoids errors in position acquisition.

[0057] Furthermore, the first roller assembly 2 includes a stepper motor 25, which is fixed on the main body 6 of the device. The output shaft of the stepper motor 25 is fixedly connected to a drive shaft 24. The drive shaft 24 is connected to a differential drive assembly 21. The differential drive assembly 21 has a first rotating shaft 22 and a second rotating shaft 28 connected to opposite sides. The first rotating shaft 22 and the second rotating shaft 28 are symmetrical about the differential drive assembly 21. A first roller 23 is fixed on the first rotating shaft 22, and a second roller 27 is fixed on the second rotating shaft 28.

[0058] The first roller 23 and the second roller 27 are both embedded in the mounting track 1;

[0059] The differential drive assembly 21 is used to drive the first rotating shaft 22 and the second rotating shaft 28 to rotate or rotate at a differential speed.

[0060] The label scanner 26 is mounted and fixed on the stepper motor 25.

[0061] In this embodiment, the first rotating shaft 22 and the second rotating shaft 28 can drive the first roller 23 and the second roller 27 by rotating themselves. In this embodiment, since it is necessary to inspect as many locations as possible in the greenhouse, there are many bends in the track 1. When the first roller group 2 and the second roller group 7 enter the bend, since the inner diameter and outer diameter of the bend are different, both the first roller group 2 and the second roller group 7 need to cope with the sliding changes at the bend.

[0062] This embodiment achieves cornering by connecting a first rotating shaft 22 to a first roller 23 and a second rotating shaft 28 to a second roller 27, utilizing the differential rotation of the first roller 23 and the second roller 27. At this point, the rotational speed of either the first rotating shaft 22 or the second rotating shaft 28 is lower at the inner diameter, while the rotational speed of either the second rotating shaft 28 or the first rotating shaft 22 is higher at the outer diameter. The differential drive assembly 21 guides the power of the stepper motor 25 and provides rotational drive or differential adjustment for the rotation of the first rotating shaft 22 and the second rotating shaft 28, thus enabling smooth cornering.

[0063] Furthermore, the differential drive assembly 21 includes a horizontal gear 211, which is fixed on the drive shaft 24. A side bevel gear 212 that meshes with the horizontal gear 211 is provided on the side of the horizontal gear 211. A synchronization frame 213 that rotates circumferentially with the side bevel gear 212 is fixed on the side bevel gear 212. A first connecting shaft 214 and a second connecting shaft 219 are provided on the synchronization frame 213. Both the first connecting shaft 214 and the second connecting shaft 219 are rotatably connected to the synchronization frame 213. The first connecting shaft 214 and the second connecting shaft 219 are symmetrically distributed about the axis of the side bevel gear 212.

[0064] A first planetary gear 215 is fixed on the first connecting shaft 214, a second planetary gear 218 is fixed on the second connecting shaft 219, and a first sun gear 216 is fixed at the end of the first rotating shaft 22. The first sun gear 216 is located between the first planetary gear 215 and the second planetary gear 218, and the first sun gear 216 meshes with both the first planetary gear 215 and the second planetary gear 218.

[0065] The end of the second rotating shaft 28 is fixed with a second sun gear 217, which is located between the first planetary gear 215 and the second planetary gear 218. The second sun gear 217 meshes with both the first planetary gear 215 and the second planetary gear 218.

[0066] In this embodiment, the horizontal gear 211 in the differential drive assembly 21 is driven by the drive shaft 24, which is driven by the stepper motor 25. The side bevel gear 212 rotates vertically and circumferentially under the drive of the horizontal gear 211, thereby driving the synchronization frame 213 to rotate circumferentially. At this time, the first planetary gear 215 on the first connecting shaft 214 and the second planetary gear 218 on the second connecting shaft 219 can drive the first sun gear 216 and the second sun gear 217 to rotate without rotating, thereby transmitting the rotational drive of the first roller 23 and the second roller 27 to the first rotating shaft 22 and the second rotating shaft 28.

[0067] When the rotational speed of the first roller 23 or the second roller 27 changes, it restricts the rotational speed of the first rotating shaft 22 or the second rotating shaft 28 in the opposite direction, thereby generating resistance to the first sun gear 216 or the second sun gear 217. At this time, the first planetary gear 215 and the second planetary gear 218 consume and change the rotational speed of the first sun gear 216 and the second sun gear 217 through their own rotation under the action of external force, thereby forming a speed difference and realizing differential speed adjustment of the first roller 23 and the second roller 27.

[0068] This embodiment avoids the obstruction that occurs when the first roller group 2 and / or the second roller group 7 slides through bends on the mounting track 1 by adjusting the differential speed of the first roller group 23 and the second roller group 27, thus making the inspection process smoother. Furthermore, the mounting of the first roller group 2 and / or the second roller group 7 enables the effective transport of the device body 6. The inspection probe 41 and the label scanner 26 on the device body 6 are used to identify and record the specific location of the spraying. Under the action of the spraying mechanism 5, precise variable-rate application of pesticides is effectively completed.

[0069] In this embodiment, precise variable-rate application involves spraying a designated location and controlling the amount of spray.

[0070] Furthermore, the main body 6 of the device includes a main frame 61, the main frame 61 is circumferentially covered with a protective plate 63, a water tank 66 is provided inside the main frame 61, and a pump 64 is provided on the side of the water tank 66. The pump 64 is connected to the spraying mechanism 5 and the water tank 66 respectively.

[0071] In this embodiment, the main frame 61 supports the overall weight of the main body 6, the protective plate 63 protects the equipment inside the main frame 61, the water tank 66 supplies water for spraying, and can hold pesticide solution for spraying application. The pump 64 discharges liquid to the spraying mechanism 5. Multiple water tanks 66 can be configured in this embodiment to carry different types of pesticide solution, pumping out the corresponding solution when needed, thereby enhancing the operability of precise variable-rate pesticide application.

[0072] Furthermore, the water tank 66 is provided with an injection port 62 at the top and a drain port 4 at the bottom. The injection port 62 penetrates the protective plate 63 and extends upward to the outside of the protective plate 63, while the drain port 4 penetrates downward through the protective plate 63.

[0073] In this embodiment, the injection port 62 is located at the top of the water tank 66, and the drain port 4 is located at the bottom of the water tank 66, which facilitates liquid injection and liquid discharge without being obstructed by the protective plate 63.

[0074] Furthermore, the spraying mechanism 5 includes a connecting pipe 54, which is connected to the pump 64. A connecting end 52 is fixed on the connecting pipe 54. A spray nozzle 53 is provided on one side of the connecting end 52, and a fan 51 is fixed on the opposite side.

[0075] The spray nozzle 53, the connecting end 52, and the connecting pipe 54 are internally connected.

[0076] In this embodiment, the connecting pipe 54 in the spray mechanism 5 is used to connect to the pump 64 to pressurize the liquid and discharge it through the spray nozzle 53 at the connection end 52. The spray nozzle 53 can atomize or spray the liquid. The fan 51 is used to send the atomized liquid or sprayed liquid to a greater distance by wind.

[0077] In this embodiment, the spraying mechanism 5 increases the coverage area through the wind force of the fan 51, and increases the spraying volume through the setting of the water tank 66, while ensuring that the required medicine solution has room for preparation.

[0078] Furthermore, a charging port 8 is provided on one side of the main body 6 of the device, and a sliding cover plate 9 is provided on the outside of the charging port 8, which can slide to cover or slide to open the charging port 8.

[0079] The main body 6 of the device is provided with several lighting lamps 3 on its side.

[0080] In this embodiment, the charging port 8 is used to replenish the power of the device body 6. The device body 6 is provided with a control box 65, which controls the operation of the device body 6. The sliding cover 9 can cover the charging port 8 by sliding to protect the charging port 8 and prevent foreign objects or liquids from entering. It can also be slid open to realize the charging operation.

[0081] In this embodiment, the sliding cover 9 is raised and lowered by a scissor arm. The bottom of the scissor arm is fixed on the main frame 61. The scissor arm can be raised and lowered by pushing the center hinge position of the scissor arm. During this process, the scissor arm can be raised and lowered to push the sliding cover 9, thereby closing or opening the charging port 8.

[0082] This embodiment utilizes lighting lamp 3 to improve the visual environment, thereby avoiding misjudgment of the precise variable drug application location due to environmental factors.
