AI Technical Summary
Existing coffee bean harvesters are prone to tipping over or sinking into the ground when used in mountainous terrain, and have low harvesting efficiency, especially for coffee beans with small central areas and small contact surfaces, which are easily damaged.
The system employs a tracked walking mechanism, a vibrating beater, and a plant gathering device. The tracked walking mechanism enhances ground grip, the vibrating beater reduces damage, and the plant gathering device reduces obstruction, thereby improving harvesting efficiency.
It enables efficient coffee bean harvesting under diverse terrain conditions, reduces damage rates, improves harvesting efficiency, and minimizes the harvesting of unripe berries.

2. The small coffee berry harvester of claim 1, wherein, The left vibrating tapping unit (201) and the right vibrating tapping unit (202) have the same structure, both including a vibrating tapping rotating shaft (203) and multiple vibrating tapping rods (204). The top end of the vibration tapping rotating shaft (203) is rotatably mounted on the connecting frame unit (101) and connected to the vibration tapping drive device, which drives the shaft to rotate relative to the connecting frame unit (101). Multiple vibrating tapping rods (204) are distributed around the vibrating tapping rotating shaft (203) and are parallel to the vibrating tapping rotating shaft (203). Each vibrating tapping rod (204) is fixedly connected to the vibrating tapping rotating shaft (203) by multiple connecting rods (205). The vibrating tapping rods (204) rotate with the vibrating tapping rotating shaft (203) to poke and vibrate the coffee plant, causing the coffee beans to fall downwards to the lower part of the left frame unit (102) and the right frame unit (103).
3. The small coffee berry harvester of claim 2, wherein, The connecting rod (205) is bent into an L-shape at one end near the vibrating striking rod (204), and the connecting rod (205) connected to the same vibrating striking rotating shaft (203) has the same bending direction.
4. A small coffee berry harvester according to claim 2 or 3, characterised in that, Both the left vibrating tapping unit (201) and the right vibrating tapping unit (202) include one or more connecting rings (206). The vibrating tapping rotating shaft (203) passes through the connecting ring (206) vertically and is coaxial with the connecting ring (206). The connecting ring (206) has a number of first protrusions (207) equal to the number of vibrating tapping rods (204) along the circumferential direction. The first protrusion (207) has a first mounting groove that mates with the vibrating tapping rod (204). The vibrating tapping rod (204) extends into the first mounting groove and is fixedly connected to the first protrusion (207).
5.
