Description

Technical Field

[0001] The present invention relates to the field of crop picking machinery, and particularly to a high-efficiency blueberry picking branch oscillator. Background Technique

[0002] A blueberry picking oscillator is an agricultural mechanical device for blueberry picking. It usually uses a vibration motor or other vibration devices to generate high-frequency vibrations. When the vibrating part contacts the blueberry branches, the vibration is transmitted to the branches, causing the branches to shake rapidly. Since the connection between the mature blueberry fruits and the branches is relatively loose, under the action of vibration, the fruits will fall off the branches.

[0003] Some blueberry picking oscillators are equipped with adjustable clamping devices, which can fix the trunk or main branches of the plant in a suitable position according to the size and shape of the blueberry plant, ensuring that the branches can vibrate fully during vibration. However, when the trunk vibrates, the blueberry roots will also shake and vibrate together, causing excessive damage or displacement to the plant, resulting in the plant being prone to toppling or even dying directly. Therefore, there is an urgent need for a high-efficiency blueberry picking branch oscillator to solve the above problems. Summary of the Invention

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1 and Figure 2 , an embodiment provided by the present invention: a high-efficiency blueberry picking branch oscillator, including a support device 1, a clamping and oscillating device 2 and a tree trunk 4, further including a clamping and fixing device 3. The clamping and oscillating device 2 is movably installed on the support device 1. There are two symmetrically arranged clamping and fixing devices 3, and the clamping and fixing devices 3 are movably installed on the support device 1. The clamping and fixing devices 3 are located below the clamping and oscillating device 2.

[0029] Please refer to Figure 4, the supporting device 1 includes a supporting framework 5. Symmetrically and fixedly connected to the middle of one side of the supporting framework 5 are two mounting parts 6. The supporting device 1 is mounted on a tractor or other traction equipment through the mounting parts 6. Fixedly connected to the side of the top of the supporting framework 5 close to the mounting part 6 is a collecting umbrella mounting plate 7. A collecting umbrella is mounted on the top of the collecting umbrella mounting plate 7, and the falling fruits are collected by the collecting umbrella. Fixedly installed on the side of the top of the supporting framework 5 close to the collecting umbrella mounting plate 7 is a servo motor 8. Fixedly installed at the driving end of the servo motor 8 is a rotating frame 9. Fixedly connected to the outer side of the end of the rotating frame 9 away from the servo motor 8 is a power push rod 10. The driving end of the servo motor 8 drives the rotating frame 9 to rotate, and the rotation of the rotating frame 9 drives the power push rod 10 to rotate. Since the power push rod 10 is located on the outer side of the end of the rotating frame 9, the rotation of the rotating frame 9 drives the power push rod 10 to rotate around the center point of the rotating frame 9. Symmetrically and fixedly installed on the side of the top of the supporting framework 5 away from the servo motor 8 are two first limiting slide rods 11. The clamping and vibrating device 2 is subjected to sliding limit through the first limiting slide rods 11. Symmetrically and fixedly installed at the bottom end of the side of the supporting framework 5 away from the mounting part 6 are four second limiting slide rods 12. A energy storage spring 13 is nested on the outer side of the second limiting slide rods 12. The clamping and fixing device 3 is subjected to sliding limit through the second limiting slide rods 12.

[0030] Please refer to Figure 5 and Figure 6 , the clamping and vibrating device 2 includes a vibrating framework 14. Fixedly connected to one end of the vibrating framework 14 is a limiting bracket 15. Fixedly installed inside the vibrating framework 14 is a first electro-hydraulic telescopic rod 16. The telescopic end of the first electro-hydraulic telescopic rod 16 is slidably connected to the inner side of the middle of the limiting bracket 15. The telescopic end of the first electro-hydraulic telescopic rod 16 is subjected to sliding limit through the limiting bracket 15, so as to reduce the friction between the telescopic end and the receiving end of the first electro-hydraulic telescopic rod 16, thereby reducing the probability of oil leakage and prolonging its service life. Fixedly installed at the end of the vibrating framework 14 away from the limiting bracket 15 is a vibrating plate 21. Fixedly installed at the telescopic end of the first electro-hydraulic telescopic rod 16 is an adjusting part 17. Symmetrically rotatably connected to the adjusting part 17 are two arc-shaped clamping plates 18. Rotating connectors 20 are respectively rotatably connected to both sides of the vibrating framework 14. The other end of the rotating connector 20 is rotatably connected to the arc-shaped clamping plate 18. Symmetrically and penetratingly opened at the bottom end of the vibrating framework 14 are limiting slide holes 25. A limiting groove 22 is penetratingly opened in the middle of the vibrating plate 21. Uniformly opened on the inner side of the arc-shaped clamping plate 18 are plug-in slots 23. An arc-shaped thickening plate 19 is movably plugged on the inner side of the arc-shaped clamping plate 18. Uniformly fixedly connected to the outer side of the arc-shaped thickening plate 19 are plug-in plates 24. The plug-in plates 24 are movably plugged inside the plug-in slots 23. The clamping thickness of the arc-shaped clamping plate 18 is adjusted through the movably plugged arc-shaped thickening plate 19. When the tree trunk 4 is thinner, the thicker arc-shaped thickening plate 19 can be replaced to clamp the tree trunk 4, which is convenient for clamping tree trunks 4 of different thicknesses.

[0031] Please refer to Figure 7 、 Figure 8 and Figure 9 。The clamping and fixing device 3 includes a support bottom plate 26, a support block 34 and a fixed straight plate 32. A plurality of anti-slip plates 27 are fixedly connected to the bottom end of the support bottom plate 26. The anti-slip plates 27 are inclined. The inclined design can increase the friction with the ground, and the support bottom plate 26 is fixed by the resistance generated by obliquely inserting into the ground. Two support members 28 are symmetrically and fixedly connected to the top end of the support bottom plate 26. A second electric hydraulic telescopic rod 29 is fixedly installed at the top end of the support bottom plate 26. The second electric hydraulic telescopic rod 29 is located between the two support members 28. A pressure sensor 30 is fixedly installed at the telescopic end of the second electric hydraulic telescopic rod 29. A control chip is electrically connected to the inside of the pressure sensor 30 through a wire, and the control chip is electrically connected to the second electric hydraulic telescopic rod 29 through a wire. The control chip issues a control instruction to the second electric hydraulic telescopic rod 29 according to the pressure data detected by the pressure sensor 30. Before use, a control instruction and a pressure threshold range are input to the control chip. When the pressure reaches the threshold range, the extension of the second electric hydraulic telescopic rod 29 is closed. When it is lower than the threshold range, the second electric hydraulic telescopic rod 29 is controlled to extend. When it is higher than the threshold range, the second electric hydraulic telescopic rod 29 is controlled to contract, so as to achieve dynamic adjustment, and the positions of the two fixed straight plates 32 are adjusted in real time when the tree trunk 4 is constantly shaking, so as to keep the root of the tree trunk 4 in a fixed state, so as to protect the root of the tree trunk 4 from damage caused by shaking. A sliding adjustment bracket 31 is fixedly connected to one side of the support bottom plate 26. A limit chute 35 is formed through the middle of the support member 28. A limit support rod 36 is slidably connected to the inside of the limit chute 35. There are three support blocks 34, and the three support blocks 34 are respectively fixedly installed at one end of the two limit support rods 36 away from the support member 28 and the driving end of the second electric hydraulic telescopic rod 29. A support shaft 33 is fixedly installed on the side of the fixed straight plate 32 close to the support bottom plate 26. The support block 34 is rotatably connected to the support shaft 33. The two limit support rods 36 apply a limit to the fixed straight plate 32 to keep it in the horizontal direction. The fixed straight plate 32 is pushed by the second electric hydraulic telescopic rod 29 to move to clamp and fix the tree trunk 4. A positioning protrusion 37 is provided at the top end of the side of the support block 34 close to the fixed straight plate 32. A positioning bevel 38 is provided at the bottom end of the side of the support block 34 close to the positioning protrusion 37. An installation hole 39 is formed through the middle of the support block 34. A thickened plate is movably inserted into the side of the fixed straight plate 32 away from the support shaft 33. The bottom end of the anti-slip plate 27 is inclined away from the fixed straight plate 32.

[0032] Please refer to Figure 2 and Figure 3The sliding adjustment bracket 31 is slidably connected to the second limit slide bar 12, one end of the energy storage spring 13 is close to the end of the sliding adjustment bracket 31 away from the fixed straight plate 32, and the other end of the energy storage spring 13 is close to the inner side of the mounting plate of the second limit slide bar 12. The energy storage spring 13 pushes the sliding adjustment bracket 31 to return to its original position. When the oscillation operation is performed, the control chip in the pressure sensor 30 continuously adjusts the extension of the second electric hydraulic telescopic rod 29, thereby pushing the sliding adjustment bracket 31 to slide on the second limit slide bar 12 and squeeze the energy storage spring 13 to contract. The oscillation frame 14 is slidably connected to the first limit slide bar 11 through the limit slide hole 25, and the power push rod 10 is slidably connected to the inner side of the limit groove 22. The rotating power push rod 10 drives the oscillation plate 21 to swing left and right through the limit groove 22, thereby driving the clamping oscillation device 2 to swing left and right on the first limit slide bar 11 to achieve the oscillation operation of the tree trunk 4.

[0033] Working principle: During use, the support device 1 is first installed on a tractor or other traction equipment through the installation part 6, and then the collecting umbrella is installed on the collecting umbrella installation plate 7. When performing vibration picking, the support device 1 is moved to the outside of the trunk 4 by external force, and then the support device 1 is lowered to the anti-slip plate 27 and inserted into the soil around the trunk 4, and then the first electric hydraulic telescopic rod 16 is retracted to vibrate and clamp the trunk 4, and the telescopic end of the first electric hydraulic telescopic rod 16 pulls the adjusting member 17 to move close to the limit bracket 15. The movement of the adjusting member 17 drives the two arcuate clamps 18 to rotate until the inner side of the arc thickened plate 19 is close to the outer side of the trunk 4, and then the root of the trunk 4 is started. The second electric hydraulic telescopic rod 29 is controlled to extend, and the telescopic end of the second electric hydraulic telescopic rod 29 pushes the support block 34 to move. The movement of the support block 34 pushes the fixed straight plate 32 to move close to the trunk 4. When the thickened plate on the fixed straight plate 32 is close to the outside of the trunk 4, the second electric hydraulic telescopic rod 29 pushes the support bottom plate 26 to move away from the trunk 4 under the push of the reaction force. Since the anti-slip plate 27 is tilted and inserted into the ground, the support bottom plate 26 is fixed to the ground through the anti-slip plate 27. When the pressure detected by the pressure sensor 30 reaches a predetermined value, the pressure sensor 30 closes the extension of the second electric hydraulic telescopic rod 29 through the control chip. At this time, the trunk 4 is fixed and can be picked;

[0034] When picking, the servo motor 8 is started. The driving end of the servo motor 8 drives the rotating frame 9 to rotate. The rotation of the rotating frame 9 drives the power push rod 10 to rotate. Since the power push rod 10 is slidably connected to the inner side of the limiting groove 22, the rotation of the power push rod 10 causes it to move up and down inside the limiting groove 22. At the same time, the limiting groove 22 drives the shock plate 21 to move left and right. The movement of the shock plate 21 drives the shock frame 14 to slide left and right on the first limiting slide rod 11. In this way, the two arc-shaped clamping plates 18 drive the trunk 4 clamped in the middle to shake left and right, so as to achieve the shock effect and shake the blueberries off the tree.

[0035] When performing the shock picking operation on the trunk 4, the root of the trunk 4 is squeezed and fixed by two fixed straight plates 32. During the shaking process of the trunk 4, the anti-slip plate 27 is continuously shaken, so that the anti-slip plate 27 and the ground become loose. At this time, the pressure sensor 30 detects that the pressure decreases intermittently, and the chip controls the second electro-hydraulic telescopic rod 29 to extend and push the support bottom plate 26 and drive the anti-slip plate 27 to move away from the trunk 4, so that the anti-slip plate 27 is always stuck on the ground, thereby strengthening the root of the trunk 4.
