Description

Technical Field

[0001] The utility model belongs to the field of agricultural machinery, and particularly relates to a modular clamping mechanism for agricultural machinery. Background Art

[0002] In the picking operation, the clamping mechanism is usually the only mechanism in direct contact between the picking machine and the operating plant. The clamping pressure, contact area, contact hardness applied by the clamping mechanism to the operating plant, as well as the quality, mechanical strength, operating distance, applicable diameter range, etc. of the clamping mechanism itself need to meet the diverse requirements in practical applications. In addition, whether the clamping mechanism can achieve effective and convenient operation has a decisive impact on the effect, efficiency, energy consumption, damage degree of the operating plant, and user experience of the picking operation.

[0003] There is currently a disclosed hydraulic vibration type oil tea fruit picking device (patent application number: CN202323330888.9), which includes a vehicle body, a power supply device, a hydraulic pump station, a small connecting plate, a hydraulic motor, a hydraulic push rod, a crank-slider mechanism, a picking device, and a sleeve assembly. The power supply device and the hydraulic pump station are both installed on the vehicle body. The sleeve assembly is rotatably connected to the vehicle body, and the lower end of the sleeve assembly is fixed to the small connecting plate. The upper end of the crank-slider mechanism is sleeved in the sleeve assembly and can reciprocate in the sleeve assembly. The lower end of the crank-slider mechanism is connected to the hydraulic motor through the small connecting plate. The hydraulic push rod is fixed to the upper end of the crank-slider mechanism. One end of the picking device is fixed to the upper end face of the crank-slider mechanism, and the other end is rotatably connected to the hydraulic push rod. The expansion and contraction of the hydraulic push rod can control the opening and closing of the picking device.

[0004] The picking structure of this solution adopts an integrated design. During design, relevant settings can often only be made according to the maximum limit, so it cannot meet many requirements in practical applications. The integrated structural design has the following disadvantages: long, heavy, clumsy, etc.; the length range of the clamping mechanism is 3 - 5 meters, and the weight is often hundreds of kilograms. When encountering situations such as a thinner diameter of the operating plant, a smaller tree crown, and an easily damaged epidermis, the clamping mechanism cannot be flexibly adjusted according to the actual situation, and disassembly, transfer, and storage are all very inconvenient.

Detailed Implementation Manner

[0024] Example 1

[0025] Such as Figure 1 And Figure 4As shown in the figure, a modular clamping mechanism for agricultural machinery includes a clamping module 1, a hydraulic module 2 and a quick-connect module 3. One end of the clamping module 1 is connected to a fruit tree, and the other end of the clamping module 1 is detachably connected to one end of the hydraulic module 2. The other end of the hydraulic module 2 is detachably connected to one end of the quick-connect module 3. The other end of the quick-connect module 3 is connected to agricultural machinery.

[0026] The quick-connect module 3 includes a third connecting flange 4 and a quick connector 5.

[0028] The clamping module 1 includes a guide rail 6, a front support arm 7, a moving support arm 8 and a rear support arm 9. The cross-section of the guide rail 6 is rectangular. The front support arm 7 and the rear support arm 9 are respectively fixed at both ends of the guide rail 6. The moving support arm 8 is sleeved on the guide rail 6 and moves between the front support arm 7 and the rear support arm 9. A connecting sleeve 10 is provided on the surface of the moving support arm 8 relative to the rear support arm 9. The rear support arm 9 is provided with a piston hole 11 and a fixing hole 12. The hydraulic module 2 includes a piston rod 13, a first hanging flange 14 and a first connecting flange 15.

[0029] The clamping module 1 can adopt various sizes to meet the requirements of different clamping diameters and contact areas.

[0030] The cross-section of the guide rail 6 being rectangular can effectively increase the contact area between the guide rail 6 and the moving support arm 8 to reduce local pressure and prevent the moving support arm 8 from rotating and displacing.

[0031] The hydraulic module 2 can adopt various cylinder diameters, piston rod diameters and wall thicknesses to meet the requirements of different clamping pressures and mechanical strengths.

[0032] The first connecting flange 15 and the third connecting flange 4 can be detachably connected by bolts and nuts, or can be connected by other fixing parts.

[0033] A traction hole 16 is provided at the front end of the guide rail 6. Rubber blocks 17 are provided on the opposite surfaces of the front support arm 7 and the moving support arm 8. The moving support arm 8 includes a U-shaped sliding sleeve 18, and a first pin shaft 19 and a bushing 20 are provided at the opening of the U-shaped sliding sleeve 18.

[0035] By adopting the U-shaped sliding sleeve 18 and the connecting sleeve 10, it is convenient to disassemble and assemble the movable support arm 8 and replace the rubber block 17.

[0036] The first pin shaft 19 can provide lateral support and reduce the moving resistance of the movable support arm 8, and the bushing 20 can prevent the opening of the U-shaped sliding sleeve 18 from deforming. The traction hole 16 at the front end of the guide rail 6 can be used to install a traction rope to assist the clamping mechanism in performing related operations.

[0039] The outer diameter and wall thickness of the connecting rod 22 can adopt various specifications to meet the requirements of different operating plants and mechanical strengths. By adding the connecting rod module 21, the length of the modular clamping mechanism is extended to have a larger application range.

[0040] Embodiment 3

The hydraulic module 2 further includes a first hanging sub-plate 27. The first hanging sub-plate 27 is provided with a second hanging hole 28 and a first limiting hole 29. A second pin shaft 30 is arranged between the first hanging hole 26 and the second hanging hole 28.

[0045] The hydraulic module 2 is hung and moved back and forth by using the second pin shaft 30 and a matching flexible cable, so it can adapt to the left and right swing and the front and back movement of the clamping mechanism during the operation, and reduce or avoid the adverse consequences such as damage to the operating fruit tree, increased operating vibration and deformation of the mechanical structure caused by excessive tension of the flexible cable. The hydraulic module 2 uses the first limiting hole 29 and a matching flexible cable to achieve the limiting function.
