Description

Technical Field

[0001] This invention relates to the field of fruit harvesting technology, and in particular to a handheld vibrating device for holding tree branches. Background Technology

[0002] Fruit harvesting has disadvantages such as high labor intensity, high labor costs, and strong seasonality, while vibration harvesting is one of the most effective ways to achieve large-scale and efficient fruit harvesting.

[0003] Currently, vibratory harvesting is primarily used for mechanized harvesting of fruits intended for processing. However, branch-based target vibration, as a selective harvesting method, allows for adjustment of the vibration location and operating parameters. Combined with a buffer collection device, it can effectively reduce fruit collision damage. Therefore, branch-clamping target vibration is an effective method for harvesting fresh fruits. The vibrator is a crucial part of the vibratory harvesting device that directly clamps and contacts the branch. During the process of vibrating and releasing the fruit, it is essential to avoid damaging the branch and also to minimize the transmission of vibrational energy to the handle, thereby reducing the operator's workload. Therefore, this invention proposes the design of a handheld branch-clamping vibration device.

[0031] The following is in conjunction with the appendix Figures 1 to 11 This application will be described in further detail.

[0032] This application discloses a handheld tree branch clamping vibration device, including a telescopic rod 1, a vibrator 3, a buffer and shock absorption mechanism 36, and a clamping mechanism 34. The fixed end of the telescopic rod 1 is equipped with a handle 2 for easy gripping, and the telescopic end of the telescopic rod 1 is equipped with a vibrator 3 for vibrating tree branches.

[0033] The vibrator 3 includes a support frame 31 with a square shell structure. The support frame 31 is connected to the telescopic end of the telescopic rod 1 through a connector 32. A vibration slide frame 33 is slidably arranged inside the support frame 31. A clamping mechanism 34 for clamping tree branches is arranged on the vibration slide frame 33. The execution end of the clamping mechanism 34 is located on the outside of the support frame 31. An eccentric rotation mechanism 35 for driving the clamping mechanism 34 to vibrate and a buffer damping mechanism 36 for reducing the vibration of the handle 2 are respectively arranged inside the support frame 31 and on both sides of the vibration slide frame 33.

[0034] In the specific implementation process, the operator holds the handle 2 to move the vibrator 3 to the branch position via the telescopic rod 1. At the same time, the operator adjusts the distance between the vibrator 3 and the handle 2 via the telescopic rod 1, which is also the distance between the operator and the branch. Then, the operator remotely controls the clamping mechanism 34 to clamp the branch. The eccentric rotation mechanism 35 then realizes the reciprocating vibration of the clamping mechanism 34 and transmits the vibration energy to the branch. The fruit is harvested by vibrating the branch. The damping mechanism 36 reduces the vibration energy transmitted to the handle 2, thereby reducing the vibration intensity on the operator's hand.

[0035] In addition, the present invention enables the vibrator 3 to rotate at any angle at the telescopic end of the telescopic rod 1 through the connector 32, so as to adapt to branches with different growth angles.

[0036] The clamping mechanism 34 includes a rotating shaft 341. Two rotating shafts 341 are symmetrically distributed within the vibrating slide frame 33. An arc-shaped clamping bar 342 is rotatably mounted on the rotating shaft 341. The two arc-shaped clamping bars 342 are symmetrically distributed with their concave surfaces facing each other. An extension bar 343 is connected to one end of the arc-shaped clamping bar 342 near the rotating shaft 341. The extension bar 343 is placed within the vibrating slide frame 33. A first rotating shaft 344 is mounted on one end of the extension bar 343 away from the rotating shaft 341. A drive bar 345 is rotatably mounted on the first rotating shaft 344. A drive block 346 is slidably disposed within the vibrating slide frame 33. Ear seats 347 are provided on both sides of the drive block 346. The end of the drive bar 345 away from the first rotating shaft 344 is rotatably mounted on the ear seat 347 via a second rotating shaft 348. An electric push rod 349 is mounted within the vibrating slide frame 33 via a mounting seat. The output end of the electric push rod 349 is connected to the drive block 346.

[0037] In the specific implementation process, when the two arc-shaped clamping bars 342 of the clamping mechanism 34 move to the tree branch, the electric push rod 349 pushes the drive block 346 to move towards the tree branch. The drive block 346 pushes the drive bar 345 to rotate via the second rotating shaft 348. The drive bar 345 then pushes the extension bar 343 to rotate via the first rotating shaft 344. The extension bar 343 then drives the arc-shaped clamping bars 342 to rotate around the rotating shaft 341 until the two arc-shaped clamping bars 342 clamp the tree branch. Afterwards... The eccentric rotary mechanism 35 is used to achieve the reciprocating vibration of the clamping mechanism 34, thereby vibrating the branches to facilitate the harvesting of fruits. After harvesting is completed, the electric push rod 349 drives the drive block 346 to move towards the initial position, which causes the drive bar 345 and the extension bar 343 to rotate towards the initial position. That is, the arc-shaped clamping bar 342 will also return to the initial position, so that the arc-shaped clamping bar 342 releases its grip on the branches, thereby allowing the clamping mechanism 34 to be removed so that the next branch can be harvested by vibration.

[0038] Symmetrically distributed guide holes 3461 are provided on the outer wall of the drive block 346, and the guide holes 3461 extend along the extension and retraction direction of the electric push rod 349. A guide bar 3462 is provided in the vibrating slide frame 33 to slide and cooperate with the guide hole 3461, so as to ensure that the drive block 346 moves along a straight line, thereby ensuring that the two arc-shaped clamping bars 342 rotate synchronously and the rotation angles are the same.

[0039] The arc-shaped clamping bar 342 has through holes evenly distributed around its circumference, and the axis of the through holes extends along the radius of the arc-shaped clamping bar 342. A clamping screw 3421 is threaded into the through hole, and a clamping plate 3422 is rotatably installed on the end of the clamping screw 3421 facing the concave surface of the arc-shaped clamping bar 342. A control handle 3423 for easy operation is installed on the end of the clamping screw 3421 away from the clamping plate 3422. A rubber buffer 3424 is installed on the end of the clamping plate 3422 away from the clamping screw 3421 to prevent the clamping plate 3422 from directly contacting the tree branch.

[0040] The present invention controls the rotation of the clamping screw 3421 by controlling the handle 3423, thereby changing the distance between the clamping plate 3422 and the arc-shaped clamping bar 342, thus enabling the clamping of branches of different thicknesses and improving the applicability of the present invention. At the same time, by providing a rubber buffer 3424 on the clamping plate 3422, the damage caused by the clamping mechanism 34 to the branches during clamping vibration is reduced.

[0041] The eccentric rotary mechanism 35 includes a strip frame 351, which is installed on the outer wall of the vibrating slide frame 33. An eccentric main shaft 354 is rotatably installed inside the support frame 31, and an eccentric disk 355 is installed on the eccentric main shaft 354. An eccentric shaft 356 is provided on the side of the eccentric disk 355 facing the strip frame 351, which is offset from the center of the eccentric disk 355, and the eccentric shaft 356 is slidably arranged inside the strip frame 351.

[0042] A rotating worm gear 357 is mounted on the eccentric spindle 354. The rotating worm gear 357 meshes with the rotating worm 358, and the rotating worm 358 is rotatably mounted on the connecting frame 359 provided on the inner side wall of the support frame 31. The rotating worm 358 is connected to the output end of the drive motor 3510, and the drive motor 3510 is mounted on the inner wall of the support frame 31 through the motor bracket 3511.

[0043] In the specific implementation process, the start of the drive motor 3510 will drive the rotating worm 358 to rotate synchronously. The rotating worm 358 will mesh with the rotating worm wheel 357 to realize the rotation of the rotating worm wheel 357. In turn, the eccentric main shaft 354 will drive the eccentric disk 355 to rotate synchronously, so that the eccentric shaft 356 on the eccentric disk 355 will rotate around the center of the eccentric disk 355. Since the eccentric shaft 356 is slidably set in the strip frame 351, the eccentric shaft 356 will drive the vibrating slide frame 33 to move back and forth through the strip frame 351, thereby realizing the reciprocating vibration of the clamping mechanism 34 driven by the vibrating slide frame 33, realizing the harvesting of the fruit.

[0044] The damping mechanism 36 includes a damping slider 361, which is slidably disposed inside the support frame 31. Multiple through holes are provided on the damping slider 361 along its sliding direction. A sliding guide rod 362 is slidably disposed in the through holes, and the two ends of the sliding guide rod 362 are respectively fixed to the inner wall of the support frame 31. A buffer spring 363 is connected between the damping slider 361 and the inner wall of the support frame 31.

[0045] In the specific implementation process, when the vibrating slide frame 33 reciprocates with the eccentric rotary mechanism 35, the vibrating slide frame 33 slides between the buffer springs 363 on both sides through the shock-absorbing slider 361, so that the vibration energy can be reduced by the buffer springs 363, thereby reducing the vibration energy transmitted to the handle 2; at the same time, the sliding guide rod 362 provided by the present invention can restrict the movement of the vibrating slide frame 33, avoid the movement direction being too small, and cause the clamping mechanism 34 to affect the clamping of the tree branch.

[0046] The connector 32 includes a spherical seat 321, which is installed on the end of the support frame 31 facing the telescopic rod 1. The end of the spherical seat 321 away from the support frame 31 has a spherical hole, and a ball bearing 322 is movably disposed in the spherical hole. The end of the support frame 31 facing the telescopic rod 1 is provided with a mounting plate 323, and an auxiliary rod 324 connected to the ball bearing 322 is provided on the mounting plate 323. A plurality of spring rods 325 are evenly connected circumferentially between the support frame 31 and the mounting plate 323 with the auxiliary rod 324 as the center. The two ends of the spring rods 325 are respectively hinged to the mounting plate 323 and the support frame 31. The telescopic end of the telescopic rod 1 is detachably installed from the mounting plate 323.

[0047] In the specific implementation process, when the clamping mechanism 34 does not match the growth angle of the branch, the operator holds the handle 2 and then moves the clamping mechanism 34 through the telescopic rod 1 so that the clamping mechanism 34 is pressed against the branch. This allows the support frame 31 to be adaptively rotated and adjusted through the cooperation of the ball seat 321 and the ball bearing 322. At this time, the spring rod 325 will also make corresponding extension and retraction changes to adapt to the rotation adjustment of the clamping mechanism 34. The extension end of the telescopic rod 1 and the mounting plate 323 are detachable, which means that the vibrator 3 or the telescopic rod 1 can be repaired or replaced later. The telescopic rod 1 can be an electric telescopic rod 1, which is more convenient for adjustment.

[0048] The handle 2 is provided with a detachable shock-absorbing rubber sleeve 21, and the outer surface of the shock-absorbing rubber sleeve 21 is provided with a raised structure 22 for anti-slip.

[0049] The implementation principle of this invention is as follows:

[0050] (1): First, the operator holds the handle 2 so as to control the vibrator 3 by controlling the telescopic rod 1. Then, according to the distance between the tree branch and the operator, the position of the vibrator 3 is adjusted by adjusting the length of the telescopic section of the telescopic rod 1 until the vibrator 3 moves to a position that matches the tree branch.

[0051] (2): With the assistance of the connector 32, adjust the angle of the clamping mechanism 34 so that the two arc-shaped clamping bars 342 of the clamping mechanism 34 can clamp the position of the branch. Then, under the push of the electric push rod 349, the clamping plate 3422 on the arc-shaped clamping bar 342 clamps and fixes the branch.

[0052] (3): Then start the drive motor 3510. With the cooperation of the rotating worm 358 and the rotating worm wheel 357, the eccentric disk 355 is rotated, which in turn causes the eccentric shaft 356 to drive the vibrating slide frame 33 to move back and forth through the strip frame 351, so as to realize the reciprocating vibration of the clamping mechanism 34, and thus the branches can be vibrated back and forth to realize the harvesting of fruits.

[0053] (4): After completion, the drive motor 3510 stops running, and then the electric push rod 349 drives the drive block 346 to reset so that the clamping mechanism 34 can be reset, thereby allowing the vibrator 3 to be removed from the branch so that the next branch can be harvested by vibration.

[0054] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
