Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a contour spraying device. Background Technology

[0002] With socio-economic development, people's demand for high-quality agricultural products is increasing, especially for fruits with high demand such as citrus and grapes. In agricultural production, plant protection is a crucial link in ensuring crop yield and quality. Traditional plant protection operations usually involve manual spraying with spraying equipment, which is labor-intensive and suffers from problems such as uneven spraying and pesticide waste.

[0003] Patent CN212519993U discloses a mobile fertilizer spraying device for grape cultivation. This device can perform mobile foliar fertilizer spraying. However, in actual use, because the angle of the spray pipe is fixed when spraying foliar fertilizer, it can only spray fertilizer vertically downwards. As a result, the angle of the spray pipe cannot be adjusted according to the growth status of the grapes and the trellis angle. In actual fertilizer spraying, some fertilizer is easily missed on the grapevines, resulting in fertilizer waste. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figures 1-4 As shown, a contour spraying device includes a base 1, a telescopic frame 2, a swing cylinder 3, a contour spraying arm 4, and a rotary drive mechanism. The telescopic frame 2 is installed at both ends of the base 1, and the swing cylinder 3, the contour spraying arm 4, and the rotary drive mechanism are installed on the telescopic frame 2. The contour spraying arm 4 is used to spray crops.

[0024] like Figure 1As shown, the telescopic frame 2 includes a vertical telescopic section 21 and a horizontal telescopic section 22. The vertical telescopic section 21 can extend and retract vertically, and the horizontal telescopic section 22 can extend and retract horizontally and swing within a vertical plane. Specifically, the fixed end of the vertical telescopic section 21 is fixed to the base 1, and the fixed end of the horizontal telescopic section 22 is located at the telescopic end of the vertical telescopic section 21. The two horizontal telescopic sections 22 are arranged opposite to each other. The swing cylinder 3 is installed on the vertical telescopic section 21 and can drive the horizontal telescopic section 22 to swing within a vertical plane.

[0025] like Figure 2 As shown, the vertical telescopic part 21 includes a vertical sleeve 211, a vertical telescopic rod 212, and a vertical drive cylinder 213. The vertical sleeve 211 (i.e., the fixed end of the vertical telescopic part 21) is fixed on the base 1. One end of the vertical telescopic rod 212 slides through the vertical sleeve 211. The horizontal telescopic part 22 is rotatably connected to the other end of the vertical telescopic rod 212, and the two horizontal telescopic parts 22 are arranged opposite to each other. The fixed end of the vertical drive cylinder 213 is installed on the base 1, and the telescopic end of the vertical drive cylinder 213 is fixedly connected to the vertical telescopic rod 212. The horizontal telescopic part 22 includes a horizontal sleeve 221, a horizontal telescopic rod 222, and a horizontal drive cylinder 223. The horizontal sleeve 221 (i.e., the fixed end of the vertical telescopic part 21) is fixed on the base 1, and the telescopic end of the vertical drive cylinder 213 is fixedly connected to the vertical telescopic rod 212. The fixed end of the horizontal telescopic part 22 is rotatably connected to the end of the vertical telescopic rod 212 (i.e., the telescopic end of the vertical telescopic part 21) by means of hinge or other means. One end of the horizontal telescopic rod 222 (i.e., the telescopic end of the horizontal telescopic part 22) slides through the horizontal sleeve 221. The other end of the horizontal telescopic rod 222 is equipped with a rotary drive mechanism and a contour spraying arm 4. The fixed end of the horizontal drive cylinder 223 is installed on the horizontal sleeve 221, and the telescopic end of the horizontal drive cylinder 223 is fixedly connected to the horizontal telescopic rod 222. The fixed end of the swing cylinder 3 is rotatably connected to the vertical telescopic rod 212 by means of hinge or other means, and the telescopic end of the swing cylinder 3 is rotatably connected to the horizontal sleeve 221 by means of hinge or other means.

[0026] The vertical drive cylinder 213 drives the vertical telescopic rod 212 to slide up and down inside the vertical sleeve 211, thereby adjusting the height of the telescopic frame 2 through vertical extension and retraction; the horizontal drive mechanism drives the horizontal telescopic rod 222 to slide back and forth inside the horizontal sleeve 221, thereby adjusting the extension distance of the telescopic frame 2 through horizontal extension and retraction; the swing cylinder 3 drives the horizontal sleeve 221 to rotate, thereby allowing the horizontal telescopic part 22 to unfold or fold through the swing of the horizontal sleeve 221.

[0027] like Figure 4As shown, the contour spraying arm 4 includes a rotating base 41, a contour spraying rod, a contour cylinder 42, and a nozzle 43. The top of the rotating base 41 is rotatably mounted on the end of the horizontal telescopic rod 222. The contour spraying rod is composed of multiple arc-shaped tubes 44 connected end to end in sequence. One end of the contour spraying rod is rotatably connected to the bottom of the rotating base 41 by means of hinge or other means. The nozzle 43 is installed on the outside of the arc-shaped tubes 44. Adjacent arc-shaped tubes 44 are connected to each other and to the rotating base 41 by contour cylinders 42. The contour cylinders 42 are located inside the arc-shaped tubes 44, so that the contour cylinders 42 can drive the arc-shaped tubes 44 to swing in the vertical plane. The overall shape of the contour spraying arm 4 can be adjusted by the swing of multiple arc-shaped tubes 44. The rotation drive mechanism can drive the rotating base 41 to rotate, which in turn can drive the contour spraying arm 4 to make horizontal circular motion.

[0028] like Figure 3 As shown, a mounting base 5 is fixed to the end of the horizontal telescopic rod 222, and a rotating shaft is fixed to the top of the rotating base 41. The rotating shaft is rotatably mounted on the mounting base 5 via a thrust bearing 6. The rotary drive mechanism includes a drive motor 7, a driving bevel gear 8, and a driven bevel gear 9. The drive motor 7 is mounted on the mounting base 5, the driving bevel gear 8 is fixed to the output shaft of the drive motor 7, and the driven bevel gear 9 is fixed to the rotating shaft and meshes with the driving bevel gear 8. Under the meshing transmission of the driven bevel gear 9 and the driving bevel gear 8, the drive motor 7 can drive the rotating base 41 to rotate via the rotating shaft, thereby enabling the contour spraying arm 4 to perform horizontal circular motion.

[0029] A medicine tank and a hydraulic pump can be installed on the base 1. The input end of the hydraulic pump is connected to the medicine tank, and then the nozzle 43 is connected to the output end of the hydraulic pump through the spray pipe. The medicine in the medicine tank can be transported to the nozzle 43 through the spray pipe by the hydraulic pump, and then the medicine is sprayed through the nozzle 43.

[0030] When spraying crops using the above-mentioned contour spraying device, this embodiment takes fruit trees as an example. First, the entire device is moved to a suitable working position. The horizontal sleeve 221 is swung by the swing cylinder 3, causing the horizontal telescopic part 22 to unfold to a state perpendicular to the vertical telescopic part 21. Then, according to the specific height and position of the fruit tree, the vertical telescopic rod 212 is extended and retracted by the vertical drive cylinder 213, and the horizontal telescopic rod 222 is extended and retracted by the horizontal drive cylinder 223, so that the rotation center of the contour spraying arm 4 is located at the center of the top of the fruit tree. Next, the contour cylinder 42 drives each arc tube 44 to swing, adjusting the shape of the contour spraying arm 4 and the spray angle of the nozzle, so that the nozzle can be aligned with the crown of the fruit tree and maintain a reasonable spraying range at the distance from the crown, completing the adjustment of spraying height, orientation and angle. Finally, the spray head 43 sprays the crown with medicine, and at the same time, the drive motor 7 drives the contour spraying arm 4 to make horizontal circular motion, thereby realizing the whole-circumference spraying operation of the crown. Two contour spraying arms can be used to spray two fruit trees simultaneously, further improving work efficiency.

[0031] The vertical drive cylinder (213), horizontal drive cylinder (223), swing cylinder (3), and contour cylinder (42) are all connected to the air pump via air pipes. Solenoid valves are connected to the air pipes. The ultrasonic sensor, solenoid valves, air pump, and drive motor (7) are all electrically connected to the controller.

[0032] To facilitate control of various operations during the spraying process, the contour spraying device of this utility model also includes a control system. Specifically, the control system includes a controller, an ultrasonic sensor, a solenoid valve, and an air pump. The controller and air pump are mounted on the base 1. The controller adopts PCL programming control, and the solenoid valve is a three-position five-way solenoid valve. An ultrasonic sensor is installed inside the arc-shaped tube 44. The vertical drive cylinder 213, the horizontal drive cylinder 223, the swing cylinder 3, and the contour cylinder 42 are connected to the air pump through an air pipe. The solenoid valve is connected to the air pipe. The ultrasonic sensor, the solenoid valve, the air pump, the drive motor 7, and the hydraulic pump are all electrically connected to the controller. During the spraying operation, the controller controls the vertical drive cylinder 213, the horizontal drive cylinder 223, and the swing cylinder 3 to extend the telescopic frame and adjust the spraying height and orientation. The ultrasonic sensor detects the distance between the nozzle 43 and the tree canopy and then feeds the detected distance vertically back to the controller. The controller then compares the received distance data with the set optimal distance range. If the detected distance value is not within the set optimal distance range, the controller controls the air pump and solenoid valve to provide power to the contour cylinder 42, causing the contour cylinder 42 to swing the arc tube 44 until the detected distance is within the optimal distance range, thus completing the shape adjustment of the contour spraying arm. Finally, the controller controls the hydraulic pump and drive motor 7 to carry out the full-circle spraying operation on the tree canopy.
