Description

Technical Field

[0001] The utility model relates to the technical field of plant protection vehicles, in particular to an adjusting device for an unmanned plant protection vehicle. Background Art

[0002] In the past, my country's airports had a large amount of exposed ground, overgrown with weeds, and frequent insect and bird activity. Airport maintenance was largely limited to mowing, a low-level approach. This resulted in unclear ground navigation signals in the airfield, becoming one of the main factors affecting aircraft navigation safety and causing significant soil erosion. Therefore, adopting rapid greening technology to plant lawns based on the climate and soil conditions of the area where the airport is located and the special vegetation requirements of the airfield is of great significance for ensuring flight safety, protecting the environment, and establishing a positive image for the airport. The seeding, fertilizing, and spraying of airport lawns primarily rely on manual labor or traditional agricultural machinery, which not only consumes a lot of manpower and time, but also makes it difficult to significantly improve efficiency. Furthermore, it poses pollution and health risks to practitioners. Therefore, unmanned plant protection equipment is crucial.

[0003] Existing unmanned plant protection vehicles are generally equipped with spraying devices that are the same width as the vehicle body, and the spraying range is very small, which in turn prolongs the working time. When encountering a larger working area, the battery life of the plant protection vehicle is also severely tested. Often, the work has not been completed yet and it has to be returned to charge, which is very inconvenient. Therefore, this application proposes a plant protection vehicle spraying device to solve the above problem. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides an adjustment device for an unmanned plant protection vehicle, which has the advantages of a large spraying range and saving time and effort. It solves the problem that unmanned plant protection vehicles in the existing technology are generally installed with a spraying device with the same width as the vehicle body, the spraying range is very small, and the working time is prolonged. When encountering a larger working area, the power of the plant protection vehicle is also severely tested. Often, the work has not been completed and it has to be returned for charging, which is very inconvenient.

[0005] In order to achieve the above-mentioned purpose of a large spraying range and saving time and effort, the utility model provides the following technical solutions: an adjustment device for an unmanned plant protection vehicle, comprising a tail frame fixedly connected to the rear of the vehicle, and the left and right ends of the tail frame are rotatably connected to two connecting rods, and a first cross bar is fixedly connected between the two upper connecting rods and the two lower connecting rods, and the ends of the four connecting rods away from the tail frame are rotatably connected to the mounting frame, and the front of the mounting frame is fixedly connected to a first spraying device, and the first spraying device includes a first support arm, and the bottom of the first arm is fixedly connected to a first nozzle.

[0006] Preferably, the top of the mounting frame is fixedly connected to two vertical rods, and the ends of the two connecting rods on the left and the two connecting rods on the right away from the tail rack respectively extend into the interior of the two vertical rods and are rotatably connected thereto.

[0007] Preferably, a support arm is fixedly connected to the top of the mounting frame, and the support arm is located between the two vertical rods.

[0008] Preferably, the top of the support arm is rotatably connected to a first electric push rod, and one end of the first electric push rod away from the support arm is rotatably connected to the first cross bar below.

[0009] Preferably, both ends of the mounting frame are rotatably connected to second supporting arms, and the opposite sides of the two second supporting arms are fixedly connected to second nozzles.

[0010] Preferably, the outsides of the first nozzle and the two second nozzles are connected to a plurality of nozzles, and the first nozzle and the two second nozzles are connected to a liquid storage tank inside the vehicle compartment.

[0011] Preferably, the front sides of the two vertical rods are rotatably connected to second electric push rods, and the ends of the two second electric push rods away from the vertical rods are rotatably connected to the two second arms respectively.

[0012] Preferably, the front faces of the two vertical rods are fixedly connected to limiting frames, the tops of the two second arms are fixedly connected to pins, and the two second electric push rods are rotationally connected to the vertical rod and the second arm on the adjacent side through two limiting frames and two pins respectively.

[0013] Compared with the existing technology, the present invention provides an adjustment device for an unmanned plant protection vehicle, which has the following beneficial effects:

[0014] The connecting device of the adjustment device of the unmanned plant protection vehicle is provided with a first electric push rod. When in use, the first electric push rod is extended to push the angle between the support arm and the lower cross bar to increase. Through the rotation connection between the connecting rod and the mounting frame, the angle between the upper end of the vertical rod and the upper connecting rod is increased, and the angle between the lower end of the vertical rod and the lower connecting rod is reduced, so that the distance between the upper connecting rod and the lower connecting rod is reduced. At this time, the support arm drives the mounting frame to extend outward, and then drives the first nozzle to extend forward through the first support arm. By providing a second electric push rod, the second electric push rod is extended to push the pin, and the pin movement drives the second arm to extend outward, which can drive the second nozzle to extend and make it parallel to the first nozzle, so that the spraying distance is longer. When the first electric push rod is retracted, the mounting frame can be raised, and then the distance between the first nozzle and the second nozzle and the ground is increased. By adjusting the distance between the nozzle and the ground, crops at different heights can be sprayed. When the work is completed, the second electric push rod retracts, pulling the pin to move toward the vehicle body, driving the second arm to fold inward, so that it is perpendicular to the mounting frame and parallel to the vehicle body. At this time, the first electric push rod retracts, the angle between the support arm and the lower cross bar becomes smaller, the angle between the upper end of the vertical rod and the upper connecting rod becomes smaller, and the angle between the lower end of the vertical rod and the lower connecting rod becomes larger, so that the distance between the upper connecting rod and the lower connecting rod becomes larger until they become parallel. At this time, the angle between the connecting rod and the tail frame becomes smaller, driving the mounting frame close to the vehicle body. At this time, the entire connecting device is in a folded state and can drive normally, thereby achieving the purpose of a large spraying range of the device and saving time and effort. It solves the problem that the unmanned plant protection vehicle in the prior art is generally installed with a spraying device of the same width as the vehicle body, the spraying range is very small, and then the working time becomes longer. When encountering a larger working area, there is also a severe test on the power of the plant protection vehicle. Often, the work has not been completed and it has to be returned to charge, which is very inconvenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] See also Figure 1-4 , an adjustment device for an unmanned plant protection vehicle, comprising a tail frame 1 fixedly connected to the rear of the vehicle, two connecting rods 2 being rotatably connected at both ends of the tail frame 1, a first cross bar 3 being fixedly connected between the two upper connecting rods 2 and the two lower connecting rods 2, the four connecting rods 2 being rotatably connected at one end away from the tail frame 1 to the mounting frame 4, a first spraying device 5 being fixedly connected at the front of the mounting frame 4, the first spraying device 5 comprising a first support arm 51, a first nozzle 52 being fixedly connected at the bottom of the first arm 51, two vertical rods 6 being fixedly connected at the top of the mounting frame 4, the two left connecting rods 2 and the two right connecting rods 2 being away from the tail frame 1 respectively extending into the inside of the two vertical rods 6 and being rotatably connected thereto, a support arm 7 being fixedly connected to the top of the mounting frame 4, the support arm 7 being located between the two vertical rods 6, and the top of the support arm 7 being rotatably connected to the first electric Push rod 8, the end of the first electric push rod 8 away from the support arm 7 is rotatably connected to the first cross bar 3 below, and both ends of the mounting frame 4 are rotatably connected to the second support arm 9. The opposite sides of the two second support arms 9 are fixedly connected to the second nozzle 10. The outsides of the first nozzle 52 and the two second nozzles 10 are connected to a plurality of nozzles, and the first nozzle 52 and the two second nozzles 10 are connected to the liquid storage tank inside the car. The fronts of the two vertical rods 6 are rotatably connected to the second electric push rods 11. The ends of the two second electric push rods 11 away from the vertical rod 6 are respectively rotatably connected to the two second support arms 9. The fronts of the two vertical rods 6 are fixedly connected to the limiting frame 12. The tops of the two second support arms 9 are fixedly connected to the pins 13. The two second electric push rods 11 are rotatably connected to the vertical rod 6 and the second support arm 9 on the adjacent side through two limiting frames 12 and two pins 13.

[0022] In summary, the connection device of the adjustment device of the unmanned plant protection vehicle is provided with a first electric push rod 8. When in use, the first electric push rod 8 is extended to push the angle between the support arm 7 and the first cross bar 3 below to increase. Through the rotation connection between the connecting rod 2 and the mounting frame 4, the angle between the upper end of the vertical rod 6 and the upper connecting rod 2 increases, and the angle between the lower end of the vertical rod 6 and the lower connecting rod 2 decreases, so that the distance between the upper connecting rod 2 and the lower connecting rod 2 becomes smaller. At this time, the support arm 7 drives the mounting frame 4 to extend outward, and then drives the first nozzle 52 to extend forward through the first support arm 51. By providing a second electric push rod 11, the second electric push rod 11 extends to push the pin 13, and the pin 13 moves to drive the second support arm 9 to extend outward, which can drive the second nozzle 10 to extend and make it parallel to the first nozzle 52, so that the spraying distance is longer. When the first electric push rod 8 is retracted, the mounting frame 4 can be lifted, thereby driving the distance between the first nozzle 52 and the second nozzle 10 and the ground to increase. By adjusting the distance between the nozzles and the ground, it is possible to achieve different heights. The angle between the upper end of the vertical rod 6 and the upper connecting rod 2 is smaller, and the angle between the lower end of the vertical rod 6 and the lower connecting rod 2 is larger, so that the distance between the upper connecting rod 2 and the lower connecting rod 2 is increased until it becomes parallel. At this time, the angle between the connecting rod 2 and the tail frame 1 is smaller, driving the mounting frame 4 close to the vehicle body. At this time, the entire connecting device is in a folded state and can be driven normally, thereby achieving the purpose of a large spraying range and saving time and effort of the device. It solves the problem that the unmanned plant protection vehicle in the prior art is generally installed with a spraying device of the same width as the vehicle body, the spraying range is very small, and then the working time is long. When encountering a large working area, there is also a severe test on the power of the plant protection vehicle. Often, the work has not been completed and it is necessary to return to charge, which is very inconvenient.
