The transport rails on the arched supports at the loading point serve as weighing rails, and the arched supports themselves function as weighing supports. Multiple pulley assemblies are placed on the guide rail system, each pulley assembly having hooks for hanging fruit. The pulley assemblies are connected by detachable connectors. A drive assembly on the closed-loop guide rail system provides power to the pulley assemblies. The weighing rails are disconnected from the transport rails at both ends and connected by barbed supports on the weighing supports. Resistance strain gauge sensors are located at both ends of the weighing rails. An equipment box is mounted on the weighing supports. A display screen is embedded in the front of the equipment box, and a microcontroller is placed inside the equipment box. The microcontroller is connected to the display screen and the resistance strain gauge sensors. The microcontroller is also connected to a Bluetooth module and an RFID reader / writer.

[0007] Preferably, in order to ensure a safe distance between two bunches of bananas, the connector includes a U-shaped hook and a steel pipe. The U-shaped hook is connected to the hook, and the steel pipe has through holes at both ends. One side of the U-shaped hook passes through the through hole from bottom to top and is locked by a nut.

[0008] Preferably, the drive assembly includes two drive wheels mounted on the transport guide rail, with each end of the bracket connected to a traveling wheel, and the motor fixed on the bracket. The motor and the two drive wheels are transmitted via a belt. The bracket has splicing holes at both ends that can be fitted onto U-shaped hooks.

[0009] Preferably, in order to ensure the accuracy of the weighing data and the continuity of the pulley sliding, there is a 1mm gap between the transport guide rail and the weighing guide rail.

[0010] Preferably, the weighing guide rail has a grooved section, the length of which matches the length of the pulley assembly. The groove on the weighing guide rail increases the friction between the pulley and the guide rail, allowing the pulley to stabilize when it reaches the middle of the guide rail, thus improving the accuracy of the weighing data.

[0011] Preferably, RFID tags are used to store information such as the fruit variety, harvest time, location, and weight. By storing this information through RFID tags, fruit information is transmitted to consumers, increasing the transparency of agricultural product information and facilitating the establishment of an agricultural product traceability system.

This utility model uses an arched support, guide rail, and pulley assembly to form a cableway-type transport weighing device; resistance strain gauge sensors are installed inside the two bearing points of the weighing guide rail to weigh the banana bunches during transportation, reducing the time cost, labor cost, and mechanical damage caused by traditional weighing.

[0014] 2. The guide rail system of this utility model can be designed and spliced ​​according to the terrain of fruit planting, which is highly applicable and operable, and is more conducive to promotion.

[0015] 3. Utilizing Bluetooth to enable communication between the mobile phone and the intelligent management system, the system receives and stores data in real time and visualizes the data, allowing managers to view and monitor the fruit's condition in real time. Compared to traditional computer-based systems, the mobile app-based system is more portable, offers greater flexibility in application scenarios, and is more convenient to use.

[0016] 4. RFID tags store information such as the time, location, and weight of fruit picking, which is then transmitted to the next link in the industrial chain, gradually realizing full industrial chain traceability of products; moreover, RFID tags are simple to operate, making it easier for other links in the industrial chain to accept and use them, which is conducive to building a traceability system for agricultural products.

[0017] 5. Each set of pulley components is connected by steel pipes, which allows fruits such as banana bunches to maintain equal distances, avoiding mechanical damage caused by the banana bunches squeezing each other, while also enabling large-angle turns and arbitrary splicing.
