Description

Technical Field

[0001] This utility model relates to the field of fruit picking equipment technology, and in particular to a portable and efficient dragon fruit picker. Background Technology

[0002] In modern agricultural production, dragon fruit, as a fruit with high economic value, is crucially harvested. Traditional dragon fruit harvesting mainly relies on manual labor, which not only consumes a lot of manpower and time, but also, with the continuous expansion of planting scale, the low efficiency of manual harvesting has become increasingly prominent. There is an urgent need for a portable and efficient harvesting device to improve harvesting efficiency, reduce labor intensity, and meet the needs of modern agricultural production.

[0003] Currently, most dragon fruit harvesting machines on the market employ simple scissor-type or clamp-type designs. Scissor-type harvesting machines use manually operated scissors to cut the dragon fruit stem; clamp-type harvesting machines use mechanical claws to grip the fruit, and then use a cutting device to complete the harvest. These machines primarily rely on manual operation or simple mechanical transmission to harvest dragon fruit.

[0004] However, existing dragon fruit harvesting machinery has significant drawbacks. During harvesting, it is difficult to stably hold dragon fruit of different sizes and shapes, easily causing fruit damage and reducing its commercial value. Furthermore, its cutting components are usually fixed in design, making replacement and maintenance difficult after wear, resulting in short equipment lifespan, high maintenance costs, and impacting harvesting efficiency and quality. This makes it difficult to meet the actual production needs for efficient and stable dragon fruit harvesting. Therefore, a portable, high-efficiency dragon fruit harvester is proposed to solve these problems. Utility Model Content

[0030] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a portable and efficient dragon fruit harvester, comprising an outer shell 1, a support cylinder 2 fixedly connected to one end of the outer shell 1, a clamping and cutting assembly provided above the support cylinder 2 for clamping and cutting dragon fruit, and a telescopic assembly provided on the inner wall of the outer shell 1 for increasing the length of the harvester.

[0031] The clamping assembly includes three fixed claws 4, which are disposed on the inner wall of the outer shell 1. A rotating shaft 13 is rotatably connected to the inner wall of the support cylinder 2. A fastening ring 14 is sleeved on one end of the fixed claw 4, and a cutting blade 5 is disposed on the other end of the fixed claw 4. A spring 16 is disposed on the inner wall of the fixed claw 4. A limit block 17 is fixedly connected to one end of the spring 16. A fixing post 15 is threadedly connected to the upper surface of the fixed claw 4. A connecting rope 11 is fixedly connected to the lower surface of the fastening ring 14, which can comfortably rest on the handle 10. A pulling block 12 is fixedly connected to one end of the connecting rope 11, and a tray 3 is fixedly connected to one end of the support cylinder 2.

[0032] Specifically, when using the harvester, align it with the dragon fruit. The three ring-shaped fixing claws 4 inside the support cylinder 2 grip the fruit. The spring 16 and the limiting block 17 inside the fixing claws 4 limit the cutting blade 5, ensuring its stable position. Pulling the connecting rope 11 and the pulling block 12 tightens the fastening ring 14, causing the fixing claws 4 to rotate around the pivot 13 and move towards the center, firmly clamping the dragon fruit. Subsequently, the cutting blade 5, fixed by the fixing post 15, cuts off the fruit stem. The tray 3 receives the harvested fruit. When replacing the cutting blade 5, simply rotate the fixing post 15 to detach it from the cutting blade 5 for disassembly.

[0033] Reference Figure 1 , Figure 4 and Figure 5 The telescopic assembly includes a telescopic rod 6, the outer wall of which is slidably connected to the inner wall of the outer casing 1. A fixed shaft 7 is fixedly connected to the outer wall of the outer casing 1. A rotating shaft 18 is rotatably connected to the inner wall of the fixed shaft 7. An eccentric wheel 19 is fixedly connected to the outer wall of the rotating shaft 18. A switch 8 is fixedly connected to one side of the outer wall of the eccentric wheel 19. A fixed rod 21 is attached to the other side of the outer wall of the eccentric wheel 19. A connecting plate 22 is fixedly connected to the outer wall of the fixed rod 21. A spring 20 is fixedly connected to one side of the outer wall of the connecting plate 22. A fixing groove 9 is provided on the outer wall of the telescopic rod 6. A handle 10 is fixedly connected to one end of the telescopic rod 6. One end of the spring 20 is fixedly connected to the fixed rod 10. The inner wall of the fixed axis 7 has a spring 20 for pushing the connecting plate 22 to move. The fixed rod 21 is slidably connected to the inner wall of the fixed groove 9 and is used to fix the telescopic rod 6. Three fixed claws 4 are arranged in a ring array inside the support cylinder 2 and are used to clamp the dragon fruit. The limiting block 17 is slidably connected to the inner wall of the cutting plate 5 and is used to limit the cutting plate 5. The outer wall of the fixed column 15 is threadedly connected to the inner wall of the cutting plate 5 and is used to fix the cutting plate 5. The outer wall of the connecting rope 11 is slidably connected to the inner wall of the outer shell 1 and is used to pull the fastening ring 14 to tighten.

[0034] Specifically, when the length of the harvester needs to be adjusted, turn the switch 8 outside the eccentric wheel 19 on the second shaft 18. The eccentric wheel 19 rotates and pushes the fixed rod 21 to disengage it from the fixed groove 9 on the telescopic rod 6. At this time, the telescopic rod 6 can slide freely inside the outer shell 1. After adjusting to the appropriate length, release the switch 8. The second spring 20 pushes the connecting plate 22 to drive the fixed rod 21 to re-engage into the fixed groove 9, fixing the telescopic rod 6. The operator can then hold the handle 10 to carry out the operation.

[0035] Working principle: When a portable and efficient dragon fruit harvester is needed, the harvester is aligned with the dragon fruit, and three fixing claws 4 arranged in a ring array inside the support cylinder 2 enclose the dragon fruit. At this time, the spring 16 and the limiting block 17 inside the fixing claw 4 can limit the cutting blade 5 to ensure its stable position. Pulling the connecting rope 11 and the pulling block 12 tightens the fastening ring 14, causing the fixing claws 4 to move towards the center. The fixing claws 4 rotate through the rotating shaft 13, thereby firmly clamping the dragon fruit. Subsequently, the cutting blade 5, which is fixed by the fixing post 15, can cut the dragon fruit stem. The tray 3 below receives the harvested dragon fruit. When the cutting blade 5 needs to be replaced, it can be disassembled by rotating the fixing post 15 to detach it from the cutting blade 5.

[0036] Furthermore, when the length of the harvester needs to be adjusted, the switch 8 on the outside of the eccentric wheel 19 on the second shaft 18 is turned, causing the eccentric wheel 19 to rotate. When the eccentric wheel 19 rotates, it pushes the fixing rod 21, causing the fixing rod 21 to disengage from the fixing groove 9 on the telescopic rod 6. At this time, the telescopic rod 6 can slide freely within the outer casing 1. After adjusting to the appropriate length, the switch 8 is released. Under the action of the second spring 20, the connecting plate 22 is pushed, causing the fixing rod 21 to re-engage into the fixing groove 9, fixing the telescopic rod 6, thus completing the length adjustment. The operator can then control the harvester by holding the handle 10.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
