Description
Technical Field
[0001] This utility model relates to the field of fruit planting technology, specifically to a fruit harvesting device. Background Technology
[0002] In the fruit and vegetable cultivation sector, manual harvesting remains the mainstream method in small and medium-sized orchards. Especially for fruits located high up, ladders or tree climbing are often required, leading to low efficiency and significant safety hazards. Recent auxiliary harvesting tools mostly employ simple shearing structures combined with telescopic poles. While these can reduce climbing requirements to some extent, they generally suffer from limitations such as cumbersome length adjustments and poor coordination between cutting and collection. With the development of precision agriculture, the market urgently needs lightweight solutions that balance high adaptability, ease of operation, and damage-free fruit collection.
[0003] Existing adjustable harvesting poles typically consist of a main pole and a sliding extension pole. For example, the length is fixed by a rack and pinion on the pole and a manually press-type buckle. The end is hinged to a scissor-type cutting component, and a net is attached to collect the fruit. Such devices usually rely on the user to operate the cutting mechanism with one hand while maintaining stable control of the pole's direction.
[0004] However, the aforementioned existing technologies have revealed significant shortcomings in application: First, length adjustment requires repeated pressing of the buckle and manual alignment of the teeth, which is extremely inconvenient when operating in the gaps between fruit trees; second, the cutting action is separate from fruit collection, and the fruit is prone to falling and being damaged during cutting, and only one fruit can be processed at a time; third, the traditional scissor structure requires both hands to operate the rod and the rope, resulting in poor stability when working at heights and easy to cause accidental cutting or missed harvesting. These defects seriously restrict the harvesting efficiency and the guarantee of fruit quality.
[0005] Based on this, the present invention designs a fruit picking device to solve the above problems. Utility Model Content
[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a fruit picking device.
[0007] To achieve the above objectives, this utility model provides the following technical solution:

An extension rod is slidably connected to the inner side of the main rod. First toothed plates are fixedly connected to both sides of the extension rod. Fixed seats are fixedly connected to both sides of the main rod. Second toothed plates are slidably connected to the inner side of the fixed seats. The rebound mechanism is installed between the fixed seats and the second toothed plates.

[0012] Furthermore, a rotating component is fixedly connected to the outside of the picking tube, and the rotating component is rotatably connected to the extension rod.
[0013] Furthermore, the reset mechanism includes a sliding plate and a tension spring. The sliding plate is slidably connected to the inner side of the right-angle groove, and the sliding plate is fixedly connected to the connecting belt. One end of the tension spring is fixedly connected to the bottom of the right-angle groove, and the other end of the tension spring is fixedly connected to the lower side of the sliding plate.
[0014] Furthermore, the harvesting tube has limiting grooves on both sides inside, and sliders are fixedly connected to both sides of the connecting strip, with the sliders slidably connected to the inside of the limiting grooves. Four sets of hooks arranged symmetrically are fixedly connected to the lower side of the harvesting tube.
[0015] Furthermore, the stretching mechanism includes a mounting base, a micro motor, a rotating shaft, and a pull rope. The mounting base is fixedly connected to the outside of the harvesting tube, and the mounting base and the connecting strip are at the same height. The micro motor is fixedly connected to the outside of the mounting base.

Combined with the storage design of the bottom hook, it realizes integrated cutting and collection. The whole process does not require hands to operate, which not only avoids fruit falling and damage, but also significantly improves continuous picking efficiency and reduces the intensity of work.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0032] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-10 A fruit picking device includes a main rod 1 and a connecting belt 15. The main rod 1, as the main supporting component of the entire device, is made of lightweight aluminum alloy. Its hollow internal structure reduces the overall weight and provides space for the installation of internal components. The connecting belt 15, as a power transmission component, is made of high-strength nylon braided belt, which can stably transmit tensile force and is not easily deformed or broken.
[0033] It also includes a spring-back mechanism, a separation mechanism, a reset mechanism, and a tensioning mechanism. These functional components work together to achieve the adjustment and picking functions of the device. An extension rod 2 is slidably connected to the inner side of the main rod 1. The extension rod 2 is made of aluminum alloy tube of the same material as the main rod 1. It achieves smooth extension and retraction through a precisely matched sliding structure. The first toothed plate 3 is fixedly connected to both sides of the extension rod 2. The first toothed plate 3 is made of quenched steel. Its serrated structure ensures reliable meshing and fixing. The fixed seat 4 is fixedly connected to both sides of the main rod 1. The fixed seat 4 is formed by stamping steel plate. It has a precise guide groove machined inside. The fixed seat 4 is connected to the internal space of the main rod 1. This through design provides the necessary space for the installation and movement of internal components. The second toothed plate 5 is slidably connected to the inner side of the fixed seat 4. The second toothed plate 5 is also made of quenched steel and forms a complementary meshing structure with the first toothed plate 3.
[0034] The spring-loaded mechanism is installed between the fixed base 4 and the second toothed plate 5. This mechanism provides the necessary elastic restoring force for length adjustment. The second toothed plate 5 and the first toothed plate 3 are engaged. This engagement structure ensures that the extension rod 2 can be reliably fixed in any position. The two sets of second toothed plates 5 and the two sets of first toothed plates 3 are arranged in a centrally symmetrical manner. This symmetrical design makes the force more balanced. The serrations of the second toothed plate 5 and the first toothed plate 3 are all right-angled triangular shapes. This special tooth shape realizes the bidirectional self-locking function.
[0035] The rebound mechanism includes a telescopic rod 6 and a compression spring 7. The telescopic rod 6 adopts a precision guide shaft structure to ensure that the second toothed plate 5 moves linearly without deviation. The compression spring 7 is made of high-quality spring steel to provide stable elastic force. Both the telescopic rod 6 and the compression spring 7 are fixedly connected between the second toothed plate 5 and the fixed seat 4. This double fixation ensures motion stability. There are several sets of telescopic rods 6 and compression springs 7, which are arranged symmetrically. Multiple sets improve overall reliability. The compression spring 7 is sleeved on the outside of the telescopic rod 6. This nested design saves space and ensures coaxiality.
[0036] The separation mechanism is installed on the outside of the main rod 1. This mechanism enables quick unlocking and facilitates length adjustment. The separation mechanism includes a screw 8 and a connecting rope 9. The screw 8 uses a plastic knob with an anti-slip texture for easy manual operation. The connecting rope 9 is made of high-strength steel wire rope to ensure that it does not deform when transmitting tension. The screw 8 is rotatably connected to the outside of the main rod 1, and its bearing structure ensures smooth rotation. The connecting rope 9 is fixedly connected to both sides of the screw 8. This double-sided connection ensures force balance. The end of the connecting rope 9 passes through the outside of the fixed seat 4 and is fixedly connected to one side of the second toothed plate 5, forming a complete force transmission path.
[0037] The end of the extension rod 2 is rotatably connected to the picking tube 10, which is made of transparent material to avoid obstructing the view and affecting the picking efficiency. The internal structure is precisely guided. The outside of the picking tube 10 is fixedly connected to a rotating part 11, which is rotatably connected to the extension rod 2. The rotating part 11 consists of two sets of fixed plates and a fixed rod. The fixed rod is fixedly connected between the two sets of fixed plates, and the two sets of fixed plates are fixedly connected to the outside of the picking tube 10. The end of the extension rod 2 is rotatably connected to the fixed rod. This design allows the picking head to be adjusted at multiple angles.
[0038] The harvesting tube 10 has a right-angle groove 12 inside. The right-angle groove 12 is precision milled to ensure guiding accuracy. The reset mechanism is installed inside the right-angle groove 12. This mechanism realizes the automatic reset of the cutting parts. The reset mechanism is installed at one end of the connecting belt 15 to form a complete power transmission chain. The reset mechanism includes a sliding plate 13 and a tension spring 14. The sliding plate 13 is made of a low-friction coefficient material to ensure smooth sliding. The tension spring 14 is made of high-quality spring steel to provide stable reset force. The sliding plate 13 is slidably connected to the inside of the right-angle groove 12. The precisely matched guiding structure ensures linear motion. The sliding plate 13 and the connecting belt 15 are fixedly connected with high-strength adhesive to ensure reliable connection. One end of the tension spring 14 is fixedly connected to the bottom of the right-angle groove 12 with an anti-loosening fixing method. The other end of the tension spring 14 is fixedly connected to the lower side of the sliding plate 13 to form a complete elastic reset system.
[0039] The other end of the connecting strip 15 is fixedly connected to a connecting bar 16. The connecting bar 16 is made of high-strength aluminum alloy profile, which combines lightweight and rigidity. Limiting grooves 18 are opened on both sides of the inside of the picking tube 10. The limiting grooves 18 are precision machined to ensure dimensional accuracy. Slider 19 is fixedly connected to both sides of the connecting bar 16. The slider 19 is made of self-lubricating material to reduce friction. The slider 19 is slidably connected to the inside of the limiting groove 18. This guiding structure ensures the linearity of the cutting motion. Four sets of symmetrically arranged hooks 26 are fixedly connected to the lower side of the picking tube 10. The hooks 26 are made of stainless steel material, which is rust-proof and durable. Cutting blades 17 are fixedly connected to the outside of the connecting bar 16. The cutting blades 17 are made of high carbon steel material and are heat-treated to maintain a sharp cutting edge.
[0040] The tensioning mechanism is installed on the outside of the harvesting cylinder 10. This mechanism provides the power required for cutting. The tensioning mechanism includes a mounting base 20, a micro motor 21, a rotating shaft 22, and a pull rope 23. The mounting base 20 is made of cast aluminum alloy to provide stable support for the motor. The micro motor 21 is a high-torque DC motor to ensure sufficient tension. The rotating shaft 22 is precision machined to ensure rotational balance. The pull rope 23 is made of high-strength Kevlar fiber, combining strength and flexibility. The mounting base 20 is fixedly connected to the outside of the harvesting cylinder 10, and anti-loosening bolts ensure reliable connection. The mounting base 20 and the connecting strip 16 are on the same plane. In this layout, the power transmission efficiency is optimized. The micro motor 21 is fixedly connected to the outside of the mounting base 20, and shock-absorbing pads are used to reduce operating vibration. The rotating shaft 22 is fixedly connected to one side of the output shaft of the micro motor 21, and a keyway connection is used to ensure torque transmission. The rotating shaft 22 is rotatably connected to the inside of the mounting base 20, and precision bearings are used to reduce rotational resistance. The pull rope 23 is fixedly connected to the outside of the rotating shaft 22, and a professional knot is used to ensure connection strength. The end of the pull rope 23 passes through the outside of the mounting base 20 and the picking tube 10 and is fixedly connected to one side of the connecting strip 16, forming a complete power transmission path.
[0041] A handle 24 is fixedly connected to the end of the main rod 1. The handle 24 is made of non-slip rubber material to provide a comfortable grip. The handle 24 has a control module installed inside. The module is waterproof and suitable for outdoor environments. The handle 24 has a control button 25 on the outside. The button is made of silicone material and has a comfortable touch. The control button 25 is electrically connected to the control module. Waterproof connectors are used to ensure reliability. The control module is connected to the micro motor 21 for communication. Shielded cables are used to reduce interference.
[0042] In this embodiment, firstly, when adjusting the length of the device before fruit harvesting, the operator tightens the connecting ropes 9 on both sides of the main rod 1 by turning the screw 8 installed on the outside of the main rod 1. The connecting ropes 9 pull the second toothed plate 5, which is slidably connected to the inside of the fixed base 4, causing it to retract into the fixed base 4 under the guidance of the telescopic rod 6. At the same time, the compression spring 7 is compressed. The retraction of the second toothed plate 5 disengages it from the first toothed plate 3 fixed on both sides of the extension rod 2. At this time, the extension rod 2 can slide freely inside the main rod 1, thereby adjusting the length of the entire harvesting device to adapt to fruit trees of different heights. After adjustment, the screw 8 is loosened, the compressed spring 7 releases its elasticity, and pushes the second toothed plate 5. The device is reset so that its saw teeth re-engage with the saw teeth of the first toothed plate 3. Since both sets of first toothed plates 3 and second toothed plates 5 are centrally symmetrically arranged and both have right-angled triangular saw teeth, the right-angled sides of the saw teeth of the first toothed plate 3 and the second toothed plate 5 can abut against each other, effectively preventing relative sliding and ensuring the stability of the extension rod 2 during operation, regardless of whether the extension rod 2 tends to retract downwards or extend outwards during the harvesting process. In addition, it should be noted that in order to improve harvesting efficiency, after harvesting fruits at one height of the fruit tree, the device is usually placed flat on the ground to adjust the extension length of the extension rod 2 for harvesting fruits at the next height of the fruit tree, avoiding repeated adjustments by workers that affect efficiency.
[0043] Secondly, during the actual fruit harvesting operation, the operator can hang the collection bag on the hooks 26 symmetrically installed on the lower side of the harvesting cylinder 10, hold the handle 24, and use the control device to guide the target fruit into the area inside the harvesting cylinder 10. Pressing the control button 25 on the handle 24 sends a signal to the micro motor 21 through the internal control module. The micro motor 21 starts, driving the rotating shaft 22 on its output shaft to rotate. The rotating shaft 22 is wound around the pull rope 23 fixed to its outside. The pull rope 23 pulls the connecting strip 16 fixed to its end. Under the sliding guidance of the slider 19 and the limiting grooves 18 on both sides inside the harvesting cylinder 10, the connecting strip 16 drives the externally fixed cutting blade 17 to move horizontally towards the center of the harvesting cylinder 10, completing the harvesting process. The cutting of the fruit's rootstock causes the fruit to fall into the storage bag below. At the same time, the movement of the connecting strip 16 drives the sliding plate 13 to slide within the right-angle groove 12 of the harvesting tube 10 via the connecting belt 15. The tension spring 14, which is fixed between the lower side of the sliding plate 13 and the bottom of the right-angle groove 12, is stretched. After one cut is completed, the micro motor 21 is reversed by the control button 25, and the rotating shaft 22 releases the pull rope 23. At this time, the stretched tension spring 14 retracts, and the connecting strip 16 and the cutting blade 17 are pulled back to their initial positions by the sliding plate 13 and the connecting belt 15, ready for the next harvest. The design of the right-angle groove 12 not only ensures that the cutting blade 17 can be accurately reset, but also optimizes the space utilization inside the harvesting tube 10, making the operation more convenient and efficient.
