[0002] The short picking cycle of pepper, the difficulty of picking and the fact that it is mostly done manually have seriously restricted the development level of pepper agricultural machinery. It is impossible to ensure the picking efficiency while increasing the labor cost. The existing pepper picking device is based on reducing the burden on pepper farmers, and the size of the pepper picking machine is greatly reduced. The storage bag is installed at the lower end of the pepper picking device, resulting in a small amount of pepper storage. When the storage bag is full, the storage bag needs to be replaced frequently, resulting in reduced picking efficiency. There are also pepper picking devices that install the motor and battery on the same device, which makes the whole machine too heavy, and the pepper grows in different heights. The pepper pickers hold the pepper picking device in one hand to pick the pepper, and long-term operation causes arm fatigue, thereby reducing work efficiency. Other pepper picking devices use double rollers to move in the opposite direction to cut the pepper, which has the problems of many peppers being damaged, unable to be completely removed, and incomplete cutting.

[0017] like Figures 1 to 7As shown, the portable portable pepper picking machine includes a chassis 5, a storage box 1 and a handheld component. The chassis 5 is the basic component of the present invention. The bottom of the chassis 5 has a mobile component 4, and the mobile component 4 drives the entire picking machine to move. The mobile component 4 can be a wheeled structure or a crawler structure. The top of the chassis 5 has a battery 6 for providing power to the entire picking machine. The storage box 1 is located at the top of the chassis 5 and is arranged at the back. The storage box 1 is used to store the picked pepper. The handheld component includes a negative pressure chamber 10 and a connecting pipe 2. The first end of the negative pressure chamber 10 is fixed with a handle 13 for handholding. The second end of the negative pressure chamber 10 is rotatably installed with a paddle 9. The negative pressure chamber 10 has a driving mechanism for driving the paddle 9 to rotate. The negative pressure chamber 10 is connected to the storage cavity 27 on the storage box 1 through the connecting pipe 2. The storage box 1 has a negative pressure machine 29, and the negative pressure machine 29 is used to generate a negative pressure environment in the storage cavity 27. When the picking machine is working, the moving assembly 4 drives the entire picking machine to move. After the negative pressure machine 29 is started, negative pressure is generated in the storage box 1, and then the negative pressure chamber 10 generates suction, and the pepper is transported to the storage cavity 27 of the storage box 1 through the connecting pipe 2 through the airflow. After the driving mechanism is started, the paddle 9 rotates, and the blade at the active end of the paddle 9 cuts the pepper to achieve picking.

[0018] To facilitate the assembly of the connecting pipe 2, Figure 4 As shown, a negative pressure port 28 is provided on the side wall of the negative pressure chamber 10, a negative pressure tube 11 is fixed on the handle 13, a first end of the negative pressure tube 11 is buckled on the negative pressure port 28 and communicates with the negative pressure chamber 10, and a second end of the negative pressure tube 11 is connected to the first end of the connecting tube 2. Figure 5 As shown, a connection hole 23 is provided on the side wall of the storage box 1, and the second end of the connection pipe 2 is buckled on the connection hole 23 on the side wall of the storage box 1, or extends into the connection hole 23. The negative pressure pipe 11 is a hard pipe, which can ensure sufficient structural strength. The connection pipe 2 is a soft pipe, which can meet the needs of the picker holding the handle 13 to move the negative pressure chamber 10.

[0019] like Figure 3As shown, the driving mechanism includes a driving motor 20, a flexible shaft 22, a worm 24 and a worm wheel 19, and the driving motor 20 is fixed on the handle 13. For the convenience of assembly, the handle 13 is a hollow structure, and a motor support plate 21 is provided on the handle 13, and the driving motor 20 is fixed on the motor support plate 21 by bolts. The worm wheel 19 is coaxially arranged with the dial plate 9, the worm 24 is meshed with the worm wheel 19 and both are located outside the negative pressure chamber 10, the first end of the flexible shaft 22 is fixedly connected to the output shaft of the driving motor 20 through the first coupling 15, and the second end of the flexible shaft 22 is fixedly connected to the worm 24 through the second coupling 17. For the convenience of assembly, a first flange bearing 16 supporting the output shaft of the driving motor 20 is provided on the handle 13, and a worm support plate 25 is provided on the negative pressure chamber 10, and a second flange bearing 18 supporting the worm shaft of the worm 24 is provided on the worm support plate 25. After the driving motor 20 is started, the flexible shaft 22 rotates accordingly, thereby driving the rotation of the worm 24 , thereby driving the rotation of the worm wheel 19 , and thereby driving the rotation of the shifting plate 9 .

[0020] In order to facilitate the removal of the peppercorns in the storage box 1, the top of the storage box 1 is provided with a sliding door 26. After closing the sliding door 26, the top of the storage box 1 is in a closed state, and the storage box 1 is in a sealed state. After closing the sliding door 26, starting the negative pressure machine 29 can create a negative pressure environment in the storage box 1. After opening the sliding door 26, the peppercorns in the storage box 1 can be removed. Figure 5 As shown, partitions are arranged around the negative pressure machine 29 , and the partitions are located in the storage box 1 . One of the partitions has an air suction hole 30 , and the air suction hole 30 is connected to the storage cavity 27 .

[0021] In order to make the entire picker move automatically following the movement of the pickers, Figure 1 As shown, the storage box 1 is located at the rear end of the chassis 5, and the front end of the chassis 5 has a vision and motion control box 7 and a vision sensor 8, and the vision sensor 8 is used to detect the position of the picker.

When the picker moves to pick other peppercorns, the visual sensor 8 detects the position of the picker, and the vision and motion control box 7 controls the working state of the mobile component 4 so that the picker moves with the picker.

[0025] The present invention installs a storage box 1 on the chassis 5 to improve the storage capacity of pepper, which is more efficient than replacing the storage bag. The paddle 9 with a blade is used to cut the pepper rhizome at one time, so that the plucking is more thorough and the damage of the pepper caused by multiple cutting is avoided. The paddle 9 has a pushing effect on the cut pepper to avoid the blockage of the pepper. The pepper fruit is sucked by negative pressure, which fundamentally improves the efficiency of pepper picking, reduces the labor intensity of pepper pickers, and reduces the cost of pepper picking.
