[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0012] In this invention, by setting up a camera and electric shears, the condition of the fruit can be observed through the camera during harvesting. Based on the captured content, the causes of bad fruit can be comprehensively analyzed, and countermeasures can be derived to reduce the rate of bad fruit, ensure the harvest, and achieve the goal of increasing economic benefits. The electric shears directly cut the fruit stems to avoid damage to the fruit and ensure the good quality rate of the fruit. At the same time, this method can reduce the labor intensity of workers and make the subsequent screening of bad fruit easier. Attached Figure Description

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0020] Example: Figure 1 - Figure 4As shown, this utility model provides a multifunctional handheld device for detecting and harvesting damaged fruit, including a handheld rod 1 and a hinge 4. The handheld rod 1 has a two-section design, and the two sections of the handheld rod 1 are hinged together by an anti-slip sleeve 5. A telescopic rod 6 is installed inside the upper section of the handheld rod 1. The telescopic rod 6 has a three-section design and can be completely retracted into the upper section of the handheld rod 1 when stored. A metal platform 23 is fixedly connected to the upper end of the telescopic rod 6. A camera 31 is installed above the metal platform 23, and an electric scissors 32 is installed above the camera 31. An operation button 2, a display screen 3, and a push switch 7 are installed on the lower section of the handheld rod 1. The display screen 3 and the camera 31 are electrically connected. The push-button switch 7 is electrically connected to the electric scissors 32. An annular frame 41 is fixedly connected to the upper middle part of the outer surface of the telescopic rod 6. A hook is provided inside the annular frame 41, and the annular frame 41 is connected to the flexible net 42 via the hook. The flexible net 42 is installed on the outer surface of the annular frame 41. A metal platform 23 is fixedly connected to the upper end of the telescopic rod 6. A horizontal servo motor 21 is fixedly connected to the upper end of the metal platform 23. A vertical bracket 24 is fixedly connected to the upper end of the horizontal servo motor 21. A vertical servo motor 22 is fixedly connected to the upper end of the vertical bracket 24. The lower ends of the camera 31 and the electric scissors 32 are both fixedly connected to the vertical servo motor 22. The operation button 2 is connected to both the horizontal servo motor 21 and the vertical servo motor 22. The servo motor 22 is electrically connected. A non-slip sleeve 5 is fitted under the lower middle section of the handheld stick 1. A microcontroller, power supply, and WiFi transmission module are installed inside the lower section of the handheld stick 1. The power supply powers the device. The microcontroller is an STM32 microcontroller equipped with an ESP8266 WiFi module, which can upload images of spoiled fruit collected by OpenMV to the cloud. This provides important information for determining the cause of spoilage. Data collected from the cloud can be used to comprehensively analyze the causes of spoilage, thereby deriving countermeasures to reduce the spoilage rate, ensure harvest, and ultimately increase economic benefits. The display screen 3 is an OpenMV wired image transmission display screen connected to the camera. Camera 31 uses an OpenMV camera, which is compact, efficient, easy to use, and scalable. It uses the powerful image processing function built into OpenMV to preprocess the acquired images: image filtering removes noise interference from the image; image segmentation is used to obtain the image region containing the fruit and remove other interfering backgrounds from the image; binarization is used to highlight the fruit features, and the image preprocessing is completed; the preprocessed image data is sent to a trained BP neural network for judgment and the judgment result is obtained. The electric scissors 32 consists of two electrically controllable reciprocating curved blades, and the curved blades are within the field of view of camera 31.
[0021] The specific settings and functions of this embodiment will be described in detail below. With the camera 31 and the electric shears 32, the condition of the fruit can be observed during harvesting. Based on the captured content, the causes of the bad fruit can be comprehensively analyzed, and countermeasures can be taken to reduce the rate of bad fruit, ensure the harvest, and achieve the goal of increasing economic benefits. With the electric shears 32, the fruit stem is cut directly to avoid damage to the fruit and ensure the good quality rate of the fruit. At the same time, this method can reduce the labor intensity of workers and make the subsequent screening of bad fruit easier.
[0022] The usage and working principle of this device are as follows: unfold the handheld rod 1, adjust the telescopic rod 6 to the required length, observe the display screen 3, adjust the servo motor rotation device to a suitable angle to align with the target for detection and fruit collection by operating the button 2, press the push switch 7 to close the electric shears 32, cut the part connecting the target fruit stem and branch, and the target fruit falls into the flexible net 42. At this point, the detection and collection of fruit is completed.
