Of course, the platform 2 is the mounting carrier for all other components in this embodiment, and other specific structures thereof are not limited. In other embodiments, those skilled in the art can arbitrarily design them according to actual needs.

A first conveying section 6 for conveying plant packs 8 is provided on the table top of the mounting table 5 on the front side of the platform 2, and a separate transport section 6 for conveying the separate from the packaging bag 81 is provided on the table top of the mounting table 5 on the rear side. In the second conveying section 18 of the plant, a chute 13 arranged obliquely downward is connected between the first conveying section 6 and the second conveying section 18. The upper end of the chute 13 is connected with the rear end of the first conveying section 6, and the lower end is connected with the second conveying section The head ends of the sections 18 are connected, and the first conveying section 6, the chute 13 and the second conveying section 18 are connected end to end to form a conveying platform. In this embodiment, the first conveying section 6 is a chain plate conveyor, the second conveying section 18 is a belt conveyor, and a bag dismantling and separating mechanism is provided between the first conveying section 6 and the second conveying section 18 . In actual use, the plant bag 8 is transported forward from the chain conveyor, and the packaging bag 81 is separated from the plants inside by the bag unpacking separation mechanism, and the rope 82 is separated from the packaging bag 81 by the rope bag extraction and separation mechanism. The material is dropped onto the second conveying section 18, and continues to be conveyed backward, so that the packaging bag 81, the plant and the rope 82 are separated from each other. Of course, in other embodiments, the specific conveying forms of the first conveying section 6 and the second conveying section 18 may be interchanged, or may be in other structural forms, or both use belt conveying or chain transmission.

Specifically, for the first conveying section 6, the first conveying section 6 is conveyed in the front-rear direction, and guide rods 7 are provided on the left and right sides of the middle position of the first conveying section 6, and between the two guide rods 7 The gap is basically the same as the width of the corresponding plant bag 8 , which can ensure that the plant bag 8 is directionally conveyed on the first conveying section 6 through the guiding action of the guide rod 7 when the plant bag 8 is loaded.

The lower saw blade bracket 16 includes support rods 161 installed across the upper part of the second conveying section 18 in the left-right direction. There are two support rods 161 . The lower saw blades 14 are respectively guided and assembled on the upper parts, and the lower saw blades 14 constitute the second cutting knives. The blades of the two second cutting knives are opposite to each other and are located on the same plane. 14 is a driving mechanism that moves along the axial direction of the support rod 161 to make the lower saw blade 14 horizontally cut the lower part of the front and rear sides of the packaging bag 81. In this embodiment, the driving mechanism is a ball screw installed on the support rod 161. mechanism and the drive motor matched with the ball screw mechanism. Of course, in other embodiments, the driving mechanism may also be a driving cylinder or a hydraulic cylinder or other transmission mechanism that realizes the axial reciprocation of the lower saw blade 14 along the support rod 161, which will not be described in detail. The distance between the two lower saw blades 14 is slightly smaller than the length of the front and rear sides of the corresponding plant bag 8 , and the upper saw blade 11 is located above the front side of the lower saw blade 14 .

With the structure set in this way, in the actual operation process, when the plant bag 8 is driven by the manipulator 9 to move horizontally backward, when the rear side of the plant bag 8 is close to the upper saw blade 11, the blade of the upper saw blade 11 starts to cut the plants. The lower left side of the bag 8, and a horizontal long slit is cut out from the lower left side of the plant bag 8. At this time, because the gap is small, the plants in the plant bag 8 cannot be dropped downward; the overall level of the plant bag 8 passes through After the upper saw blade 11, under the continuous driving of the manipulator 9, the plant bag 8 moves vertically downward, and moves to the right position of the two lower saw blades 14, and at this time the lower saw blade 14 and the plant bag 8 are on the Then the lower saw blade 14 is driven to move to the right by the driving mechanism. In the process of moving to the right, the blades of the two lower saw blades 14 cut the lower part of the sides of the front and rear sides of the plant bag 8.

At this time, the plant bag 8 is cut by the upper saw blade 11 and the lower saw blade 14, and its lower part is cut into a U-shaped incision, and only one side is not cut. At this time, the bottom of the plant bag 8 is cut. The packaging surface is automatically opened by the weight of the plants and sags naturally. The plants in the plant pack 8 are dropped from the packaging bag 81 to the second conveying section 18, and continue to be conveyed backward through the second conveying section 18, while the chute The arrangement of 13 ensures that during the moving and cutting process of the plant bag 8, the bulk material initially falling from the plant bag 8 slides into the second conveying section 18 through the chute 13 to realize the automatic collection of the bulk material.

In the above-mentioned operation process, the manipulator 9 needs to be fully driven, and in this embodiment, the manipulator 9 includes a frame 106, and the frame 106 is provided with two grippers 10 for grabbing the upper positions of the opposite sides of the plant bag 8, The gripper 10 is provided with a gripping hook 104 inserted into the packaging bag 81 , and the gripper 10 also has a blocking plate 105 blocked on the side surface of the packaging bag 81 . And the two grippers 10 are suspended above the position between the two guide rods 7 in the initial installation state. When the plant bag 8 is guided and transported to the preset position below the manipulator 9 through the guide rod 7, the robot 3 . After signal detection, the control manipulator 9 grabs the front and rear sides of the plant bag 8 that has reached the preset position through the gripper 10, and then performs the above-mentioned action process. During this process, when the plants fall from the plant bag 8 , in order to quickly unload the material, the manipulator 9 shakes up and down to dump all the bulk material inside the plant bag 8 onto the second conveying section 18 .

In addition, a bag collection bin 1 is provided on the left side of the table 2 between the two support rods 161. After the plant blanking is completed, the manipulator 9 removes the packaging bag 81 from the top of the second conveying section 18, and Put it into the bag collection bin 1.

Further, in order to ensure that the plant bag 8 stops moving after moving down to the set position so that the lower saw blade 14 is aligned with the long slit cut by the upper saw blade 11, thereby realizing the cutting of the U-shaped incision, the manipulator 9 is also configured with a limited position. In this embodiment, the limit structure is a limit switch provided on the manipulator 9 for controlling the limit position of the vertical movement of the arm of the manipulator 9 . After grabbing the plant bag 8, the manipulator 9 is at a certain height, and then moves down a set distance, the limit switch is turned on, the manipulator 9 stops falling, and the lower saw blade 14 is just aligned with the cutting of the upper saw blade 11 at the long seam position.

In this embodiment, the pressing plate 101 is a leveling rubber seat, which has high durability and will not cause damage to the packaging bag 81. Of course, in other embodiments, the material of the pressing plate 101 can be selected according to the actual situation Plastic, rubber and other materials. After the manipulator 9 grabs the plant bag 8 , the pressing mechanism works, the driving cylinder 102 drives the pressing plate 101 to press down on the upper end surface of the plant bag 8 , and compresses the rope 82 . After the upper saw blade 11 completes cutting the plant bag 8, the rope 82 on the plant bag 8 is also cut off. At this time, due to the action of the pressing plate 101, the rope 82 is still suspended on the plant bag 8. At this time, it needs to pass through the rope bag. The extraction and separation mechanism separates the rope 82 from the plant bag 8 .
