Description

Technical Field

[0001] The utility model relates to the technical field of pesticide sprayers, in particular to a pesticide sprayer for pomelo planting. Background Art

[0002] During the planting process, pomelo needs to be sprayed with pesticides for maintenance. At present, the spraying operation is mainly operated manually. For example, the traditional backpack sprayer requires workers to wear the sprayer and spray each pomelo tree one by one while walking. Although the backpack sprayer is highly portable, it is heavy, which brings greater workload to the workers. In addition, the amount of liquid medicine required for a single tree cannot be accurately controlled manually. Spraying too much or too little will affect tree maintenance. Utility Model Content

[0003] The utility model aims to solve the shortcomings in the prior art and provides a spraying machine for planting pomelo.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] A medicine liquid inlet is provided on the top of the medicine liquid box, and the medicine liquid inlet is located below the rotating disk.

[0011] In a preferred technical solution, the liquid medicine spraying cylinder is an electric piston cylinder, and a spray head is provided at the front end of the liquid medicine spraying cylinder.

[0012] In a preferred technical solution, synchronous motors for driving the rotating arms to rotate circumferentially are also provided on the outer surfaces of the mounting frames on both sides, so that the rotating arms on both sides maintain a synchronous rotating state.

[0013] In a preferred technical solution, the medicine liquid inlet is designed as an open structure, and the side of the medicine liquid inlet facing the swing arm is designed as a bevel.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In this embodiment, refer to Figure 1-3A spraying machine for planting pomelo includes a frame 1, and a movable wheel 15 is arranged at the bottom of the frame 1. A liquid medicine tank 2 is arranged on the frame 1, and mounting frames 3 are arranged along the edges of the top surface of the liquid medicine tank 2. The inner surfaces of the mounting frames 3 are arranged with rotating arms 4, fixed shafts 5 and rotating disks 6. The rotating arms 4, fixed shafts 5 and rotating disks 6 on both sides are located in corresponding positions. Specifically, as shown in the attached figure Figure 1 As shown,

[0024] The rotating arm 4 is located at the upper right corner of the mounting frame 3. The movable end of the rotating arm 4 is rotatably fixed with a connecting arm 7. The fixed shaft 5 is located at the bottom of the mounting frame 3. The swing arm 8 is rotatably mounted on the fixed shaft 5. The rotating disk 6 is located at the upper left corner of the mounting frame 3. A guide block 9 is arranged between the two opposite rotating disks 6. The sliding column 10 is inserted into the guide block 9. It should be noted that a through hole for the sliding column 10 to be inserted is provided in the center of the guide block 9. The column length of the sliding column 10 is more than twice the depth of the hole. The length of the sliding column 10 needs to be much longer than the depth of the hole. The purpose is to ensure that the sliding column 10 will not be separated from the guide block 9 during the back and forth sliding process.

[0025] A liquid medicine spraying cylinder 11 is disposed at the lower end of the sliding column 10. The liquid medicine spraying cylinder 11 is an electric piston cylinder, and a spray head 12 is disposed at the front end of the liquid medicine spraying cylinder 11. The liquid medicine spraying cylinder 11 can automatically extract liquid medicine, and can also automatically spray liquid medicine outward.

[0026] It should also be noted that the end of the connecting arm 7 on the same side is rotatably fixed to the middle position of the swing arm 8, and the ends of the swing arms 8 on both sides are rotatably mounted on the outer walls of the liquid spray cylinder 11 on both sides.

[0027] The outer surfaces of the mounting frames 3 on both sides are also provided with synchronous motors 13 for driving the rotating arms 4 to rotate in a circumferential direction. The rotating arms 4 on both sides are driven by the synchronous motors 13 to keep rotating synchronously.

[0028] A liquid medicine inlet 14 is provided at the top of the liquid medicine tank 2, and the liquid medicine inlet 14 is located below the rotating disk 6. Here, the liquid medicine inlet 14 is designed as an open structure, and the side of the liquid medicine inlet 14 facing the swing arm 8 is designed as a bevel. The right side of the liquid medicine inlet 14 is designed as a bevel, the purpose of which is to ensure that the liquid medicine can smoothly enter the liquid medicine tank 2 during the swinging process of the liquid medicine spraying cylinder 11, and also to ensure that the liquid medicine can smoothly rotate out of the liquid medicine tank 2 during the swinging process of the liquid medicine spraying cylinder 11.

[0029] Start the synchronous motor 13. During the circumferential rotation of the rotating arm 4, the connecting arm 7 periodically pulls or pushes the swing arm 8 to achieve flipping. The swing arms 8 on both sides are simultaneously rotated and fixed on the liquid medicine spraying cylinder 11. Therefore, the liquid medicine spraying cylinder 11 is driven by the swing arm 8 and swings synchronously. Because the guide block 9 provided at the upper end of the liquid medicine spraying cylinder 11 is fixedly installed on the rotating disk 6, the final effect that can be achieved is that the liquid medicine spraying cylinder 11 flips back and forth within a range of approximately 90°. Moreover, because the sliding column 10 fixedly provided at the upper end of the liquid medicine spraying cylinder 11 can slide in the guide block 9, the liquid medicine spraying cylinder 11 is in a downward state or a horizontal state, and it can be further extended forward. When the liquid medicine spraying cylinder 11 enters the liquid medicine tank 2 and further probes into the tank, the liquid medicine can be smoothly extracted. When the liquid medicine spraying cylinder 11 rotates out until it is in a horizontal state and further protrudes forward, it can be used to spray the liquid medicine. Since the capacity of the liquid medicine spraying cylinder 11 is fixed, the amount of liquid medicine sprayed at a time is also fixed, so that excessive or insufficient spraying of liquid medicine can be avoided, thereby ensuring the smooth growth of pomelo trees.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
