[0002] In recent years, with the rapid development of agricultural machinery automation technology, the efficiency of agricultural production, the reduction of labor intensity and the reduction of product costs have become important driving forces for the continuous advancement of this field. However, while pursuing high efficiency, we must also pay attention to the various problems and hidden dangers that may exist in the use of mechanical equipment. The widely used handheld nut picker has played a significant role in improving picking efficiency and reducing the burden on workers, but the inertial impact phenomenon in it cannot be ignored.

[0003] The inertial impact phenomenon mainly occurs during the use of the picker, especially at the handle. Since the picker needs to vibrate and shake constantly during operation, this dynamic action will cause a strong inertial impact force at the handle. This impact force will not only damage the precision parts inside the picker, but also aggravate the wear and aging of the internal parts of the picker, affecting the stability and safety of the picker.

DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0025] Embodiment: A hand buffer mechanism of a handheld nut picker, as shown in the attached Figure 1-5 As shown in the attached Figure 2-3 As shown, the nut picker includes a handheld portion 1 and a picking portion. Figure 1 and attached Figure 4As shown, the hand buffer mechanism includes a limit plate 10 slidably arranged on the upper end of the hand-held part 1 and a fixed rod 5 arranged in the inner cavity of the hand-held part 1. A gripping handle 8 is arranged above the limit plate 10, and both ends of the gripping handle 8 pass through the limit plate 10 and are sleeved on the fixed rod 5. A first fixed block 6 is arranged in the inner cavity of the hand-held part 1. The fixed rod 5 passes through the first fixed block 6 and is sleeved with springs 9 on both sides. One end of the spring 9 is connected to the end of the gripping handle 8, and the other end of the spring 9 is connected to the first fixed block 6. This structure enables the gripping handle 8 to be maintained in a specific position when not subject to external force. When the harvester starts working, the gripping handle 8 can be buffered along the fixed rod 5 through the spring 9, avoiding damage to the precision parts inside the harvester caused by inertial impact, reducing the wear and aging of the internal parts of the harvester, and enhancing stability and safety; at the same time, the hand will also be buffered by the spring 9, effectively reducing the vibration and impact force on the hand, greatly improving the comfort of the picking process. As shown in the attached Figure 5 As shown, three fixing grooves 2 are provided above the inner cavity of the hand-held portion 1, and a first fixing block 6 is fixed in the fixing groove 2 in the middle, and a second fixing block 7 is fixed in the fixing grooves 2 on both sides, and a fixing rod 5 is arranged between the second fixing block 7 and the first fixing block 6. The fixing groove 2 can play a role in positioning and supporting the first fixing block 6 and the second fixing block 7. A handle slide 3 is also provided above the rear end of the hand-held portion 11, and the rear ends of the holding handle 8 are arranged in the handle slide 3. A limit plate slide 4 is provided at the upper end of the fixing groove 2, and both ends of the limit plate 10 are slidably arranged in the limit plate slide 4. Through the handle slide 3 and the limit plate slide 4, a path can be provided for the buffering of the buffering mechanism. When the holding handle 8 slides, the limit plate 10 will also slide in the limit plate slide 4, thereby ensuring the stability of the buffering trajectory of the holding handle 8. As shown in the attached Figure 1 As shown, the gripping handle 8 includes a first handle shell 11 and a second handle shell 12, and the first handle shell 11 and the second handle shell 12 are fixedly connected by bolts to form a complete gripping handle 8. The limiting plate 10 is composed of two parts on the first handle shell 11 and the second handle shell 12. This structure is not only convenient for manufacturing, but also makes it easier to repair and replace the handle, thereby improving the maintainability of the entire mechanism. A handle connecting seat 14 is provided at both ends of the first handle shell 11 and the second handle shell 12, and a spring 9 connects the handle connecting seat 14 at the end of the gripping handle 8 with the first fixed block 6. This enables the spring 9 to play a role of buffering and resetting when the gripping handle 8 slides. The handle connecting seat 14 is located below the limiting plate 10, and the fixed rod 5 is inserted into the handle connecting seat 14. A connecting sleeve 15 is provided in the handle connecting seat 14, and the connecting sleeve 15 is sleeved on the fixed rod 5. The gripping handle 8 can be stably connected to the fixed rod 5 through the handle connecting seat 14 and the connecting sleeve 15. Preferably, as shown in the attached Figure 2As shown, shock-absorbing patches 13 are provided on both sides of the hand-held portion 11, and the outer layer of the gripping handle 8 is made of silicone material, which further improves the comfort of the user's grip and has a certain anti-slip performance, which helps to increase the stability of the grip.

[0026] Working process

[0027] When the hand-held portion 11 does not start working, the grip handle 8 is in an initial position, and the spring 9 is in a natural state without being compressed or stretched.

[0028] When the handheld part 11 starts to work, the movement and vibration of the mechanical parts inside the handheld part 11 will generate inertial impact force. At this time, the grip handle 8 will slide along the fixed rod 5 through the handle connecting seat 14 and the connecting sleeve 15 according to the inertial impact force, and at the same time drive the limit plate 10 to slide in the limit plate sliding groove 4.

[0029] During the sliding of the grip handle 8, the spring 9 begins to work. The spring 9 is compressed, and absorbs and buffers the inertial impact force through its elastic potential energy, reducing the damage to the precision parts inside the hand-held part 11. At the same time, the buffering effect of the spring 9 is also transmitted to the user's hand, reducing the vibration and impact force of the hand, and improving the comfort of the picking process.

[0030] When the inertial impact force disappears or weakens, the spring 9 begins to recover its original length, and pushes the gripping handle 8 to slide along the fixing rod 5 back to the initial position through its elastic force.

[0031] In summary, the utility model can avoid the harm of inertial impact to the handheld part, prolong the service life, and is safe and stable.
