Description

Technical Field

[0001] The invention relates to the field of crop picking machinery, in particular to a blueberry efficient picking branch oscillator. Background Art

[0002] The blueberry picking vibrator is an agricultural mechanical equipment used for blueberry picking. It usually uses a vibration motor or other vibration device to generate high-frequency vibration. When the vibrating component contacts the blueberry branch, the vibration will be transmitted to the branch, causing the branch to shake rapidly. Since the connection between the ripe blueberry fruit and the branch is relatively loose, the fruit will fall off the branch under the action of vibration.

[0031] See also Figure 7 , Figure 8 and Fig. 9 The clamping and fixing device 3 includes a supporting base plate 26, a supporting block 34 and a fixed straight plate 32. The bottom end of the supporting base plate 26 is fixedly connected with a plurality of anti-skid plates 27. The anti-skid plates 27 are inclined. The inclined design can increase the friction between the anti-skid plates and the ground. The supporting base plate 26 is fixed by the resistance generated by oblique insertion into the ground.

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. The control instruction and the pressure threshold interval are input to the control chip before use. When the pressure reaches the threshold interval, the extension of the second electric hydraulic telescopic rod 29 is closed. When the pressure is lower than the threshold interval, the second electric hydraulic telescopic rod 29 is controlled to be extended. When the pressure is higher than the threshold interval, the second electric hydraulic telescopic rod 29 is controlled to be retracted, thereby realizing dynamic adjustment. When the trunk 4 is continuously adjusted, During shaking, the positions of the two fixed straight plates 32 are adjusted in real time to keep the root of the trunk 4 in a fixed state, so as to protect the root of the trunk 4 from damage caused by shaking. A sliding adjustment bracket 31 is fixedly connected to one side of the support base plate 26. A limited position slide groove 35 is provided in the middle of the support member 28.

The fixed straight plate 32 is pushed to move by the second electric hydraulic telescopic rod 29 to clamp and fix the tree trunk 4. A positioning protrusion 37 is provided on the top of the support block 34 close to the fixed straight plate 32, and a positioning chamfer 38 is provided on the bottom of the support block 34 close to the positioning protrusion 37.

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.

[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, and 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 limit groove 22, the rotation of the power push rod 10 causes it to move up and down on the inner side of the limit groove 22, and at the same time, the limit groove 22 drives the vibration plate 21 to move left and right. The movement of the vibration plate 21 drives the vibration frame 14 to slide left and right on the first limit slide bar 11, thereby driving the trunk 4 clamped in the middle to shake left and right through the two arc-shaped clamping plates 18, thereby achieving the effect of vibration, and shaking the blueberries off the tree;

[0035] When the trunk 4 is subjected to vibration harvesting operation, the root of the trunk 4 is squeezed and fixed by the two fixed straight plates 32. The anti-slip plate 27 is driven to shake continuously during the shaking of the trunk 4, thereby causing looseness between the anti-slip plate 27 and the ground. At this time, the pressure sensor 30 detects that the pressure is intermittently reduced, and controls the second electric hydraulic telescopic rod 29 to extend through the chip to push the supporting 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 reinforcing the root of the trunk 4.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
