Description

Technical Field

[0001] This invention belongs to the field of coffee processing technology, specifically a solar-powered intelligent coffee sorting and drying integrated machine. Background Technology

[0002] Coffee is a beverage made from roasted and ground coffee beans. It contains caffeine and has effects such as refreshing the mind, promoting urination, and preventing gallstones.

[0003] Yunnan's small-bean coffee is one of the highlights of Yunnan's distinctive agriculture. Currently, Yunnan Province accounts for over 97% of the country's coffee planting area, making it my country's largest coffee bean production base and a very important coffee planting base. It has gradually formed an integrated development pattern encompassing planting, production, and processing. Traditional coffee sorting and drying processes rely primarily on manual labor. The drying process requires workers to turn the coffee beans regularly, and the sorting process involves workers manually picking out defective beans. This is labor-intensive, time-consuming, and energy-intensive, resulting in high labor costs. Furthermore, the sorting process depends on the worker's personal experience, leading to fluctuations in selection standards and inconsistent quality even within the same batch of coffee. Summary of the Invention

The moisture sensor is embedded on both sides of the inner wall of the drying platform. The double-layer rake is fixedly installed on the outer wall of the moving rod. The moving rod is located above the drying platform.

[0008] Furthermore, the drive assembly is provided in two sets, and each set of the drive assembly includes a limit sensor, a servo motor, a gearbox, a lead screw, a slider, and a limit block.

[0009] Furthermore, the limit sensor is fixedly mounted on the outer wall at both ends of the sliding guide rail.

The control box automatically analyzes the location of defective coffee using a vision system and automatically controls a vacuum pump to move above and remove the defective coffee. Sensors detect the moisture content of the coffee; when the moisture content reaches a certain level, the process automatically stops and an alert is issued. This achieves automatic turning and sorting of the coffee during the drying process, improving work efficiency, reducing labor intensity, and solving the problems of manual turning and manual selection of defective coffee during the drying process. Furthermore, this invention has a simple structure, low production cost, and is easy to maintain. It is suitable for Yunnan's long hours of sunshine and high light intensity, making it easy to widely promote. Attached Figure Description

This moisture detection device is existing technology, and suitable and mature moisture detection devices can be purchased from the market according to customer needs. The moving rod 2 is located above the drying platform 1. There are two sets of drive components. Each set of drive components includes a limit sensor 14, a servo motor 15, a gearbox 16, a lead screw 22, a slider 23, and a limit block 24. The limit sensor 14 is fixedly installed on both ends of the sliding guide rail 13. On the wall, the defective fruit screening camera 27 is fixedly installed on both sides of the vacuum pump body 25, symmetrically arranged, for capturing images of the target fruit and transmitting them to the visual recognition device inside the control box 8. This visual recognition device can be a suitable and mature visual recognition device purchased on the market according to customer needs. The specific model of the device will not be described here. The visual recognition device uses computer vision technology, such as image recognition algorithms, to analyze the color, shape, etc. of the fruit to distinguish between good and bad fruit. The defective fruit suction port 26 is used to suck up the defective fruit, the vacuum pump body 25 is used to generate the required vacuum suction, and the defective fruit spray port 28 is used to spray out the defective fruit.

[0032] Working principle:

[0033] First, the drying platform 1 is moved to the designated drying position using the casters 7 on the support legs 6. Solar panels 12 convert the energy into electricity, and the photovoltaic charging controller 10 completes the conversion, storing the energy in the battery 9. The battery 9 then powers the electrical equipment. Next, coffee berries are evenly spread inside the drying platform 1. One servo motor 15 is then activated, driving the slider 23 via the gearbox 16 and lead screw 22. The slider 23 drives the moving rod 2 and the double-layer rake 3, causing them to reciprocate inside the drying platform 1, ensuring the coffee berries are evenly distributed. During the drying process, the moisture detection device inside the control box 8 monitors the moisture content of the coffee berries in real time using the moisture sensor 4. Simultaneously, another servo motor 15, via the gearbox 16 and lead screw 22, drives the slider 23, causing the moving beam 17 to reciprocate on the drying platform 1. Then, the synchronous motor 18 drives the pulley 19 to rotate, and the transmission belt 20 drives the vacuum pump body 25 to reciprocate on the transverse slide rail 21. At this time, with the drying platform 1 as a reference, the vacuum pump body 25 and the defective fruit screening camera 27 move in a wave pattern above the drying platform 1. The defective fruit detection camera captures images of coffee cherries and transmits them to the visual recognition device inside the control box 8. The visual recognition device inside the control box 8 judges the quality of the cherries through image processing and analysis, controls the vacuum pump body 25 to move above the defective cherries and turn it on, sucks away the defective cherries through the defective fruit suction port 26, and quickly discharges the defective cherries through the defective fruit spray port 28. When the moving beam 17 moves to one end of the drying platform 1, the moving rod 2 and the double-layer rake 3 are activated, so that the coffee cherries are turned over. The defective fruit selection component is activated again to complete the visual recognition and selection of defective cherries again. When the moisture sensor 4 determines that the moisture content of the coffee cherries meets the requirements, the drying is stopped.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
