Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a portable banana fruit grabbing device used for cleaning and disinfecting bananas after harvest. Background Art

[0002] Bananas are a pillar industry for rural revitalization in southern my country's tropical and subtropical regions, particularly in hilly and mountainous areas. Post-harvest banana processing primarily involves picking, combing, cleaning and disinfection, packaging, and transportation. Cleaning and disinfection is essential, as the surface of bananas, after being picked and combed in the field, inevitably contains residues of pesticides, insect eggs, debris, and juice. Therefore, cleaning is necessary to remove these foreign matter. The cleaning water also contains a specific combination of chemicals to effectively disinfect the bananas while preserving the combed cuts. This helps extend the shelf life of the bananas during subsequent packaging, storage, and transportation, and prevents them from rotting and spoiling. While post-harvest banana processing has been mechanized to varying degrees, cleaning and disinfection still relies primarily on manual placement and handling of the bananas.

The transmission rack 241 and the push rod rack 231 are arranged opposite to each other and staggered along the width direction of the incomplete gear 22. The other end of the transmission rod 24 extends out from the other side of the elbow 21 and is connected to a number of jaws 12, which is used to drive the opening or closing of the plurality of jaws 12. A reset mechanism 4 for driving the closing and resetting of the plurality of jaws 12 is provided between the push rod 23 and the elbow 21.

[0027] The number of the clamping jaws 12 can be selected according to actual conditions. The number of the clamping jaws 12 can be 2-6. In this embodiment, the number of the clamping jaws 12 is 4.

[0028] like Figure 2 As shown, the elbow 21 is V-shaped, and the angle of the elbow 21 in this embodiment is 45°.

[0029] Externally threaded tubes 213 are provided at both ends of the elbow 21, and an incomplete wheel axle 214 is provided in the inner cavity of the elbow 21 near the inner bend. The axis of the incomplete wheel axle 214 is perpendicular to the plane where the axis of the elbow 21 is located. The incomplete gear 22 of this embodiment is an incomplete outer ring gear, which is coaxially sleeved on the incomplete wheel axle 214 and can rotate on the incomplete wheel axle 214.

[0030] like Figure 3 、 4 As shown, in order to facilitate assembly, the elbow 21 of this embodiment includes a first elbow portion 211 and a second elbow portion 212 that are matched. The first elbow portion 211 and the second elbow portion 212 are of the same size and shape. The external threaded tube 213 is fixedly connected to both ends of the first elbow portion 211. The inner cavity of the first elbow portion 211 is provided with a first incomplete axle 2141 near the inner bend. The inner cavity of the second elbow portion 212 is provided with a second incomplete axle 2142 near the inner bend.

The first incomplete axle 2141 and the second incomplete axle 2142 are matched to form an incomplete axle 214.

[0031] In this embodiment, the push rod 23 and the transmission rod 24 are both cylindrical rods and are adapted to the inner diameter of the external threaded tube 213 of the elbow 21 .

[0032] like Figure 2 、 3 As shown, the reset mechanism 4 includes a retaining ring 41 provided on one side of the push rod 23 close to the push rod rack 231, and a reset spring 42 is sleeved on the push rod 23, one end of the reset spring 42 abuts against the retaining ring 41, and the other end of the reset spring 42 abuts against the elbow 21.

[0033] like Figure 2 、 3 As shown, the fixing seat 11 of this embodiment is columnar, and the fixing seat 11 is provided with a columnar hollow cavity 111. A plurality of connecting blocks 112 are arranged around the outer side of the fixing seat 11. The connecting block 112 is provided with an embedding groove 1121 passing through the axis of the cavity 111. The embedding groove 1121 extends toward the cavity 111 and is connected to the cavity 111. One end of the clamping jaw 12 is embedded in the embedding groove 1121 and is hinged to the connecting block 112. The side of the clamping jaw 12 close to the connecting block 112 is provided with a sector gear 121 extending toward the cavity 111. The end of the transmission rod 24 away from the transmission rack 241 is provided with a cylindrical rack 242. The cylindrical rack 242 extends into the cavity 111 and engages with the plurality of sector gears 121.

[0034] like Figure 2 The figure shows a cross-sectional view of the jaws 12 in their natural state, closed and reset. Under the action of the reset spring 42, the push rod 23 moves away from the elbow 21. The push rod rack 231 on the push rod 23 drives the meshing incomplete gear 22 to rotate clockwise, and the side of the incomplete gear 22 eventually abuts against the inner wall of the elbow 21 and stops rotating. During the clockwise rotation of the incomplete gear 22, the incomplete gear 22 also synchronously drives the meshing transmission rack 241 to move linearly, thereby driving the cylindrical rack 242 on the transmission rod 24 toward the elbow 21. The meshing sector gears 121 drive the jaws 12 to rotate on the connecting block 112, closing and resetting the jaws 12.

[0035] like Figure 3 As shown, a push rod slot 232 is provided on the push rod 23 between the push rod rack 231 and the retaining ring 41. The push rod slot 232 extends along the axial direction of the push rod 23. A push rod pin 5 is threadedly connected to the elbow 21 and is embedded in the push rod slot 232. The cooperation between the push rod pin 5 and the push rod slot 232 prevents the push rod 23 from rotating in the circumferential direction, allowing the push rod rack 231 on the push rod 23 to be stably engaged with the incomplete gear 22, thereby ensuring the reliable operation of the drive mechanism 2.

[0036] like Figure 3As shown, a transmission slot 243 is provided on the side of the transmission rod 24 near the transmission rack 241. The transmission slot 243 extends along the axial direction of the transmission rod 24. The elbow 21 is threadedly engaged with the transmission rod pin 6 that is embedded in the transmission slot 243. The cooperation between the transmission rod pin 6 and the transmission slot 243 prevents the transmission rod 24 from rotating in the circumferential direction, allowing the transmission rack 241 on the transmission rod 24 to be stably engaged with the partial gear 22, thereby ensuring reliable operation of the drive mechanism 2.

[0037] like Figure 2 、 3 As shown, the connecting tube 3 of this embodiment includes a mounting tube 31, a sleeve 32 and a locking screw 33. One end of the connecting tube 3 is threadedly connected to the elbow 21, and the other end of the connecting tube 3 is provided with an external thread and is threadedly connected to the sleeve 32. The outer side of the other end of the sleeve 32 is fixedly connected to the handle 321, and the locking screw 33 is threadedly connected to the side of the mounting tube 31 close to the sleeve 32.

[0038] The locking screw 33 and sleeve 32 rotate on the external threads of the mounting tube 31. By rotating the sleeve 32 relative to the external threads of the mounting tube 31, the combined length of the mounting tube 31 and sleeve 32 can be adjusted to ensure that the end of the push rod 23 extends beyond the end of the sleeve 32 in its natural position. This allows the push rod 23 to be pressed during operation, allowing the jaws 12 to open and grasp the banana fruit. Furthermore, by rotating the sleeve 32 to adjust the handle 321 and elbow 21 to the appropriate angle and position, the locking screw 33 is then used to lock the handle. This adapts to different worker habits, facilitating better grasping of banana fruit and improving operational efficiency.

[0039] like Figure 2 、 3 As shown, in order to improve the stability when pressing the push rod 23, ensure the linear movement of the push rod 23, and realize the reliable engagement of the push rod rack 231 with the incomplete gear 22, a columnar pressing portion 233 is provided at one end of the push rod 23 away from the push rod rack 231, and the outer diameter of the pressing portion 233 is adapted to the inner diameter of the sleeve 32.

[0040] like Figure 1 As shown, in order to prevent the clamping claw 12 from causing mechanical damage to the banana fruit when clamping the banana fruit, in one embodiment, one end of the clamping claw 12 away from the fixing base 11 is fixedly connected to a flexible claw sleeve 122 .

[0041] like Figure 2As shown, the clamping jaws of the device are in the closed reset state in the initial state. Holding the handle 321, the thumb presses the pressing portion 233 of the push rod 23, and the push rod 23 drives the push rod rack 231 to move toward the elbow 21. The push rod rack 231 drives the incomplete gear 22 meshing with it to rotate counterclockwise. The incomplete gear 22 rotates counterclockwise and drives the transmission rack 241 meshing with it to move away from the elbow 21. The transmission rack 241 drives the cylindrical rack 242 on the transmission rod 24 to move away from the elbow 21, thereby driving the several sector gears 1 meshing with it. 21 rotates, eventually driving the plurality of clamping jaws 12 to open; after aligning the opened clamping jaws 12 with the banana fruit to be grasped, the pressure on the pressing portion 233 is released. Under the action of the reset spring 42, the push rod 23 moves away from the elbow 21. The driving mechanism 2 and the above-mentioned opening process of the clamping jaws 12 act in the opposite direction. Finally, the plurality of clamping jaws 12 clamp the banana fruit. After the worker places the clamped banana fruit into the disinfection tank, he presses the pressing portion 233 of the push rod 23 again to open the plurality of clamping jaws 12 again, thereby releasing the banana fruit, thereby completing the process of clamping and releasing the banana fruit.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
