Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural planting and harvesting equipment technology, specifically relating to a nut harvester. Background Technology
[0002] Nut harvesters are tools or equipment used to assist in harvesting nuts, designed to improve harvesting efficiency, reduce labor intensity, and minimize damage to fruit trees. They include manual and mechanical types. Manual tools include long poles, clamps, or tree shakers, while mechanical types may include handheld electric harvesters or large tractor-trailer-drawn equipment.
[0003] Among the current harvesting equipment, manual tools rely on manpower, resulting in slow harvesting speed and increased labor costs. Mechanized equipment depends on flat terrain and is difficult to use in hilly, mountainous, or terraced orchards. Moreover, mechanized equipment is expensive, automation technology is immature, and most equipment is designed for specific types of nuts. Different nuts have different physical characteristics, making the equipment incompatible. There is a type of mechanized vibrating harvesting head on the market that uses a robotic arm to grip and use high-frequency vibration to detach the nuts, which are then picked up and collected from the ground. However, the detached nuts are prone to shell damage, reducing their commercial value. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model designs a nut harvester, which uses a telescopic rod structure to cover different types of fruit trees. The nuts are dislodged by vibrating the harvesting head, and the dislodged nuts are directly transported from the conveying channel inside the rod to the collection device at the lower end. It is compatible with multiple types of nuts, improves harvesting and collection efficiency, reduces labor costs, and adds a tripod to adapt to different terrains, making operation more convenient.
[0005] The nut harvester of this utility model includes a first connecting rod, a second connecting rod sleeved on the top of the first connecting rod, and a locking mechanism provided at the sleeve interface. Conveying pipes are opened inside the first and second connecting rods, and a collection bag is connected to the end of the conveying pipes. A motor base is connected to the top of the second connecting rod through a conical slide. An electromagnetic vibrator is installed on one side of the motor base, and multiple sets of vibrating arms are also installed on the motor base. Elastic covers are connected between the vibrating arms.
[0006] The inner wall of the conveying pipe is covered with flexible rubber.
[0007] The locking mechanism consists of an upper limiting ring and a lower limiting ring connected to each other with an opening at the front end. The upper limiting ring is fitted onto the second connecting rod, and the lower limiting ring is fitted onto the first connecting rod.
[0008] The bottom of the first connecting rod is also connected to a universal ball, which is installed inside a spherical hinge seat. A fixed seat is connected to the outside of the spherical hinge seat, and a foot is connected downward on the fixed seat.
[0009] The top of the tripod is hinged to the connecting block on the outer wall of the fixed base.
[0010] The tripod is configured as a telescopic rod, and an adjusting bolt is provided at the telescopic point.
[0011] The first connecting rod is also equipped with a control button, which is electrically connected to the electromagnetic vibrator.
[0012] The bottom of the first connecting rod is also provided with a tapered buffer tube, and a hook is provided on the outer wall of the tapered buffer tube, on which a collection bag is hung.
[0013] The beneficial effects of this utility model are:
[0014] This utility model adopts a telescopic pole design, which is convenient to carry and transfer when retracted, and can cover different fruit trees when extended, making it widely applicable. An additional tripod structure is added, with adjustable position and length to adapt to complex terrains such as slopes, hills, and terraces. The connecting rod is connected to the tripod via a ball joint, allowing operators to directly hold the connecting rod to control direction and position during harvesting, reducing workload, improving efficiency, and maintaining flexibility. Alternatively, the tripod can be detached for handheld operation, meeting different scenarios. The harvesting head uses a semi-automatic clamping mechanism for branches, and the vibrating arm pulses to cause the fruit to fall, further improving harvesting efficiency. The fallen fruit directly enters the conveying pipe inside the connecting rod, and is output to the collection bag via a bottom buffer pipe. An elastic protective cover is formed between the vibrating arms to prevent the fallen fruit from falling to the ground and breaking. A hook is provided at the bottom of the connecting rod for easy fixing of the collection bag. The conveying pipe is wear-resistant and can be extended and retracted according to the telescopic pole, with a diameter sufficient to meet the output space of most nuts. Attached Figure Description

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Example 1
[0024] To reduce labor during nut harvesting and adapt to complex terrains such as hills and mountains, this embodiment proposes a nut harvester. Please refer to [link / reference]. Figures 1 to 4 It includes a first connecting rod 1 and a second connecting rod 2 sleeved thereon. A locking mechanism 6 is provided at the interface. The locking mechanism 6 consists of an upper limiting ring and a lower limiting ring with an opening at the front end and connected at the rear end. A universal ball 3 is threadedly connected to the bottom of the first connecting rod 1. The universal ball 3 is connected to the fixed seat 5 through a ball joint 4. The fixed seat 5 and the leg 8 are hinged through a connecting block 7. A slot is provided on the connecting block 7. The angle of the leg 8 can be adjusted through the slot. The leg 8 has a two-section structure. An adjusting bolt 17 is provided at the section.
[0025] When using the harvester, the second connecting rod 2 slides out from the inner wall of the first connecting rod 1 according to the height of the fruit tree. After the height is adjusted, the bolt on the locking mechanism 6 is tightened to lock it. The upper bolt is fixedly sleeved on the upper limiting ring of the second connecting rod 2, and the lower bolt is fixedly sleeved on the lower limiting ring of the first connecting rod 1. The rear ends of the upper and lower limiting rings are connected to lock the first and second connecting rods. The telescopic rod structure is easy to carry when folded and can cover different types of fruit trees when unfolded, making it widely applicable. At the same time, the angle of the leg 8 can be adjusted according to the terrain elevation through the slot on the connecting block 7, and the height can be adjusted through the telescopic structure of the leg 8. After adjustment, the adjusting bolt 17 is tightened to lock it, adapting to different terrains such as slopes, terraces, and hills. At this time, the harvester is fixed. Since the first connecting rod 1 is connected to the fixed base 5 by a ball joint structure, the first connecting rod 1 can rotate freely. The worker only needs to hold the first connecting rod 1 to control the direction to carry out the harvesting work. Compared with the traditional hand-held pole harvesting, it greatly reduces the labor of the workers, increases work efficiency, and does not lose flexibility.
[0026] To improve harvesting efficiency and ensure the harvesting head is compatible with different types of nuts, the first connecting rod 1 and the second connecting rod 2 are equipped with conveying pipes. The upper end of the first connecting rod 1 is connected to the motor base 13 via a slide rail 12. The motor base 13 is electrically connected to the control button 11 on the first connecting rod 1. The motor base 13 is equipped with a vibrating arm 14, and a clamping block 15 is fixed to the end of the vibrating arm 14. Multiple vibrating arms 14 are connected by an elastic cover 16, and the bottom of the elastic cover 16 is connected to the slide rail 12.
[0027] The motor base 13 includes an electromagnetic vibrator and a clamping controller (this is prior art and will not be described in detail here). The vibrating arm 14 is retracted by the control button 11. The clamping block 15 on the vibrating arm 14 fixes the tree stem. The vibration mode is switched and transmitted to the tree stem through the clamping block 15. The clamping block 15 is made of silicone to avoid damage to the branches caused by vibration. Intermittent pulse vibration is used to simulate the manual "shaking and pausing" action to improve the detachment efficiency. The elastic cover 16 wraps the target fruit to prevent the fruit from falling out. The detached fruit enters the conveying pipe through the slide 12 and is output from the buffer tube 9 end of the conveying pipe. The end of the first connecting rod 1 is provided with a hook 10 to fix the collection bag. The buffer tube 9 can reduce the impact at the fruit output end. This process is compatible with a variety of nut types and improves work efficiency. At the same time, the use of an automatic collection device simplifies the workflow and further improves the harvesting efficiency.
[0028] In addition, the first connecting rod 1 and the universal ball 3 are threaded together and can be removed separately to meet hand operation and increase flexibility. The motor base 13 and the slide rail 12 are threaded together and can be disassembled for easy replacement and maintenance. The conveying pipe is made of flexible rubber material, which has good elasticity and wear resistance, and can be stretched and contracted. The inner diameter is 80mm, which can meet the conveying space of most nuts.
[0029] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not describe all details exhaustively, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
