Description

Technical Field

[0001] This utility model relates to the field of coconut food processing technology, specifically a coconut shell crushing machine. Background Technology

[0002] Coconut is an important tropical fruit and a significant source of tropical woody oil. The coconut food processing industry primarily uses mature, old coconuts, which not only have sweet coconut water but also fragrant coconut meat. Coconut water is rich in electrolytes, making it a natural sports drink, while coconut meat contains up to 33% oil, a significant source of medium-chain fatty acids.

[0003] However, the shelling process in the processing of mature coconuts has always been a constraint on the industry's development. Currently, there are three methods for shelling coconuts in the coconut food processing industry. The first method involves manually sawing the mature coconut in half, scooping out the coconut meat with a knife, and then manually peeling off the husk to obtain the raw material. The second method involves workers holding the mature coconut and pressing it on a shell-breaking machine to promote the shell's cracking and removal, followed by manual peeling off the husk. These two methods are currently the most common, but they suffer from low production efficiency, high labor costs, and safety hazards. The third method involves manually taking the coconut to a shell-breaking station where a machine breaks the shell. This method is still in its initial stage, with no commercially available prototypes in industrial applications, and its production efficiency and shelling effectiveness are unknown. Utility Model Content

An air valve 302 is located on one side of the mechanical claw 301, which can drive the mechanical claw 301 to grasp the coconut according to its size. After grasping the coconut, a motor 6 is activated, driving the main drive wheel 8 to rotate.

The main conveyor belt 101 is installed on the worktable 1, and a fixed placement seat 13 is installed on the main conveyor belt 101. A rotating plate 1301 is rotatably installed at the bottom of the fixed placement seat 13, and a pusher is installed on one side of the rotating plate 1301. The sensor, when in contact with the drive rod 103, moves under the push, causing the rotating plate 1301 to rotate the fixed placement seat 13. A limit rod 16 is also provided at the bottom of the fixed placement seat 13, which limits the rotation angle of the rotating plate 1301 to approximately 45 degrees. Infrared sensing ends 1302 are provided on both sides of the rotating plate 1301. These infrared sensing ends 1302 transmit signals after the rotating plate 1301 has been rotated and positioned, temporarily pausing the transmission of the main conveyor belt 101 to facilitate the cutting and shelling of coconuts located on the fixed placement seat 13. A discharge slope 102 is provided at one end of the workbench 1, and a [missing information - likely a device or structure] is located directly below the discharge slope 102. A vibrating screen box 14 is provided, and a feeding slope 102 allows the coconuts that have been cracked to fall into the vibrating screen box 14. A screen plate is provided inside the vibrating screen box 14, which is shaped with the left side higher than the right side. One end of the screen plate is connected to the inner wall of the vibrating screen box 14 with a movable rotating shaft. An extension plate 17 is provided on the outer wall of the vibrating screen box 14, and an electric cam 1701 is provided on the extension plate 17. The electric cam 1701 can drive the push plates 18 connected to both ends of the screen plate to move upward on the sliding groove and the sliding groove 1401. After moving upward, the push plates 18 can pull the tension spring 1802, so that the screen plate can vibrate and screen the coconuts on the screen plate, so that the coconut fragments after cracking fall onto the waste conveyor belt 15, which facilitates the shell separation and the subsequent coconut meat removal.

[0026] Working Principle: In operation, a feeding ramp 102 is first installed at one end of the workbench 1 to feed coconuts from above the shell-crushing machine into the vibrating screen box 14. The vibrating screen box 14 contains a screen plate, which is oriented with the left side higher than the right. One end of the screen plate is connected to the inner wall of the vibrating screen box 14 with a movable rotating shaft, allowing the screen plate to vibrate up and down. A shell-crushing box 2 is located in the center of the workbench 1, and robotic arms 3 are installed on both sides of the shell-crushing box 2. The robotic arms 3 can extend under the drive of the second sensor 305, allowing them to contact the coconuts located on the fixed placement seat 13. A first telescopic rod 303 is slidably installed at one end of the robotic arm 3, and a robotic claw 301 is fixedly connected to one end of the first telescopic rod 303. A first hydraulic rod 304 is installed between the robotic claw 301 and the robotic arm 3. Through the extension and retraction of the first hydraulic rod 304, the robotic claw 301 can grip the coconuts according to their size. A pneumatic valve 302 is fixedly connected to one side of the mechanical gripper 301, and the pneumatic valve 302 can drive the opening and closing action of the mechanical gripper 301.

[0027] Next, the motor 6 is started, and the output end of the motor 6 is fixedly connected to the main drive wheel 8. The main drive wheel 8 is connected to the auxiliary drive wheel 9 via the belt 10. The auxiliary drive wheel 9 drives the cutting blade 19 to rotate via the shaft. Then, the third sensor 12 is started, which can drive the second hydraulic rod 11 to extend. One end of the second hydraulic rod 11 is provided with a push block 1101, which is located in the slide rail 401. When the push block 1101 moves, it can push the drive plate 5 to rotate via the connecting rod 20, so that the cutting blade 19 slides in the waist groove and moves towards the coconut after being clamped, thereby performing the coconut shell breaking work.

[0028] Finally, a fixed placement seat 13 is rotatably mounted on the top of the workbench 1, and a rotating plate 1301 is rotatably mounted on the bottom of the fixed placement seat 13. Infrared sensing terminals 1302 are located on both sides of the bottom of the rotating plate 1301. Push sensors are in contact with drive rods 103. When the push sensors are pushed by the drive rods 103, the rotating plate 1301 will cause the fixed placement seat 13 to rotate. A limit rod 16 is also provided at the bottom of the fixed placement seat 13, which can limit the rotation angle of the rotating plate 1301, restricting it to approximately 45 degrees. In this way, the coconut located on the fixed placement seat 13 can be tilted to facilitate gripping and cutting / cracking by the robotic claw 301.
