DETAILED DESCRIPTION

[0023] The following is combined with Figure 1 -Attached Figure 2 , further details of this application are given.

[0024] Example 1:

[0025] A mountain fruit picking machine, referring to Figure 1 and Figure 2 , including a frame 1, a V-shaped frame 2, a pull rope 3 and a driving mechanism 4. The frame 1 is fixed on the ground, the V-shaped frame 2 is arranged on the top surface of the frame 1, and the V-shaped frame 2 is arranged upward, and one end of the V-shaped frame 2 is a driving end 21, the other end of the V-shaped frame 2 is a connecting end 22, and the corner of the V-frame 2 is a rotating end 23. The rotating end 23 is rotatably connected to the frame 1, one end of the pull rope 3 is connected to the connecting end 22, and the other end of the pull rope 3 is used to be tied to the tree trunk. The driving mechanism 4 is connected to the connecting end 22 of the V-shaped frame 2 and is used to drive the connecting end 22 to rotate around the rotating end 23.

[0026] When picking fruits with hard peels that are not easily damaged when falling, the mountain fruit picking machine is used for picking. First, one end of the pull rope 3 is tied to the connecting end 22 and the other end is tied to the tree trunk. At this time, the driving end 21 is driven by the driving mechanism 4 to rotate back and forth around the rotating end 23, so that the connecting end 22 is rotated back and forth around the rotating end 23. When the connecting end 22 rotates in the direction away from the trunk, the pull rope 3 is pulled, so that the pull rope 3 pulls the trunk to swing toward the frame 1. When the connecting end 22 rotates in the direction close to the trunk, the pull rope 3 is relaxed, and the trunk is reset at this time, thereby realizing the shaking of the trunk. The above process is repeated to make the trunk shake continuously, so that the fruit falls from the trunk, and the fruit is picked. Since the trunk drives all the fruits on the crown to shake together, the fruit picking efficiency is high and the fruit can be picked quickly.

[0027] Furthermore, two V-shaped frames 2 are provided along the X-axis direction, and the two V-shaped frames 2 are symmetrically spaced apart from each other. A reel 7 is provided between the connecting ends 22 of the two V-shaped frames 2, and the two ends of the reel 7 are respectively rotatably connected to the two V-shaped frames 2. Two pull ropes 3 are provided, and both pull ropes 3 are fixedly connected to the reel 7. When the fruit is picked, the reel 7 is rotated to wrap the pull rope 3 around the reel 7 to realize the winding of the pull rope 3 and reduce the knotting phenomenon of the pull rope 3 during the storage and retrieval process.

[0028] Furthermore, a rotating motor is provided on one of the V-shaped frames 2 and is fixedly connected to the connecting end 22, and the output end of the rotating connection is fixedly connected to the reel 7. When the rotating motor is running, the reel 7 is driven to rotate, thereby realizing the winding and unwinding of the reel 7. In other embodiments, a handle can be fixedly connected to the reel 7, and by rotating the handle, the reel 7 is driven to rotate, thereby realizing the winding and unwinding of the pull rope 3.

[0029] The driving mechanism 4 includes a telescopic member 41, a first connecting rod 42, a second connecting rod 43 and a third connecting rod 44. In this embodiment, the telescopic member 41 adopts a telescopic cylinder or a telescopic oil cylinder or an electric telescopic rod, and the telescopic member 41 can be fixed on the tractor 8 driven by the staff, and the tractor 8 provides stable support for the telescopic member 41, and the telescopic member 41 is horizontally arranged to provide a horizontal driving force along the Y-axis direction; one end of the first connecting rod 42 is hinged to the output end of the telescopic member 41, and the first connecting rod 43 is hinged to the output end of the telescopic member 41. 2 The other end is hinged to one end of the second link 43, one end of the third link 44 is hinged to the driving end 21, the other end of the third link 44 is hinged to one end of the second link 43 away from the first link 42, the middle part of the second link 43 is hinged to the frame 1, the hinge point between the first link 42 and the second link 43 is higher than the hinge point between the second link 43 and the frame 1 along the Z-axis direction, and the hinge point between the third link 44 and the second link 43 is lower than the hinge point between the second link 43 and the frame 1 along the Z-axis direction.

[0030] During the operation of the driving mechanism 4, the telescopic part 41 extends, pushing the first connecting rod 42 to move toward the second connecting rod 43, thereby driving the second connecting rod 43 to rotate around the hinge between the second connecting rod 43 and the frame 1, so that the second connecting rod 43 pulls the third connecting rod 44 to move diagonally downward, thereby causing the driving end 21 to rotate around the rotating end 23, so that the pull rope 3 pulls the tree trunk to shake.

[0031] Furthermore, a torsion spring 5 is provided between the rotating end 23 and the frame 1. One end of the torsion spring 5 acts on the rotating end 23, and the other end of the torsion spring 5 acts on the frame 1. In this embodiment, the torsion spring 5 is fixedly connected to the rotating end 23 and the frame 1 respectively. By providing the torsion spring 5, the stability of the rotation of the rotating end 23 is increased. During the contraction of the telescopic member 41, the V-shaped frame 2 can be reset under the drive of the torsion spring 5.

[0032] Example 2:

[0033] The structure of this embodiment 2 is substantially the same as that of embodiment 1, and the difference lies in the improvement of the frame 1.

[0034] Reference Figure 2 The frame 1 includes an outer frame 11, a longitudinal beam 12 and a cross beam 13. The longitudinal beam 12 is fixedly connected to the outer frame 11 along the Y-axis direction. A slide groove 121 is opened in the middle of the longitudinal beam 12. The cross beam 13 is arranged along the X-axis direction and inserted into the slide groove 121 and can slide in the slide groove 121. Both ends of the cross beam 13 are slidably connected to the outer frame 11. A spring 6 is arranged in the slide groove 121. One end of the spring 6 acts on the cross beam 13 and the other end of the spring 6 acts on the inner wall of the slide groove 121. In this embodiment, the two ends of the spring 6 are fixedly connected to the cross beam 13 and the inner wall of the slide groove 121 respectively. In other embodiments, one end of the spring 6 is fixedly connected to the inner wall of the slide groove 121 and the other end of the spring 6 abuts against the cross beam 13, or one end of the spring 6 abuts against the inner wall of the slide groove 121 and the other end of the spring 6 is fixedly connected to the cross beam 13.

[0035] The rotating end 23 of the V-shaped frame 2 is rotatably connected to the crossbeam 13 and can move along with the crossbeam 13 . The middle portion of the second connecting rod 43 is rotatably connected to the longitudinal beam 12 .

[0036] When the pull rope 3 pulls the trunk to bend in the direction close to the frame 1, the telescopic member 41 contracts and resets. At this time, the pull rope 3 is relaxed, and the trunk recovers under the action of its own toughness. When the trunk recovers to the vertical state, the pull rope 3 is in a straight state. However, since the trunk naturally recovers from the bent state, there is a tendency for the trunk to bend away from the frame 1 when it recovers to the vertical state. Since the pull rope 3 is in a straight state when the trunk is vertical, when the trunk bends in the direction away from the frame 1, it will pull the pull rope 3, generating a large pulling force on the V-shaped frame 2 and the frame 1, which can easily cause the frame 1 and the V-shaped frame 2 to deform.

[0037] After the spring 6 is set, when the trunk bends away from the frame 1, the pull rope 3 will pull the V-shaped frame 2, causing the V-shaped frame 2 to drive the crossbeam 13 to slide toward the trunk, thereby buffering the V-shaped frame 2 and the frame 1 and reducing damage to the frame 1 and the V-shaped frame 2.

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
