[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figure 1-3As shown, in this embodiment, a shearing device for lychee packaging includes a workbench 1, and a No. 1 feeding mechanism 2, a shearing mechanism 3, a material-pickup mechanism 4 and a loading mechanism 5 are arranged on the top of the workbench 1. The shearing mechanism 3 includes a guide frame 31, and the top of the guide frame 31 is fixedly connected to a driving motor 32, and the output end of the driving motor 32 is transmission-connected to a No. 1 bevel gear 33. The top of the guide frame 31 is rotatably connected to a rotating shaft 34, and the outer surface of the rotating shaft 34 is fixedly connected to a No. 2 bevel gear 35, and the outer surface of the No. 2 bevel gear 35 is meshed with the outer surface of the No. 1 bevel gear 33. The two ends of the rotating shaft 34 are fixedly connected to a rotating disk 36, and one end of the rotating disk 36 and near the edge position are rotatably connected to an adjusting Rod 37, the other ends of the two adjusting rods 37 are rotatably connected to the driven plates 38, one side of the two driven plates 38 is respectively slidably connected to the two sides of the guide frame 31, and the bottom ends of the two driven plates 38 are fixedly connected to the cutters 39. Among them, by setting the feeding mechanism 5, the accumulated materials can be neatly arranged and fed into the No. 1 feeding mechanism 2. By setting the No. 1 feeding mechanism 2, the lychees can be fed with limited space to improve the shearing effect. By setting the No. 1 bevel gear 33 and the No. 2 bevel gear 35, the kinetic energy of the drive motor 32 can be transferred to the rotating shaft 34. By setting the rotating disk 36 and the adjusting rod 37, the cutter 39 can be driven to move up and down reciprocatingly to achieve the shearing effect.

[0023] like Figure 1 and Figure 4 As shown, the material-selecting mechanism 4 includes a support frame 49, and two guide through holes 41 are provided on the top of the support frame 49. Slide blocks 42 are slidably provided on the inner surfaces of the two guide through holes 41, and the bottom ends of the two slide blocks 42 are fixedly connected to the toggle rods 43. The top surface of the inner part of the support frame 49 is rotatably connected to two rotating wheels 44, and the outer surfaces of the two rotating wheels 44 are connected to the transmission belts 45 for transmission. One side of the two slide blocks 42 is fixedly connected to the outer surface of the transmission belt 45, and the top of the support frame 49 is fixedly connected to the forward and reverse motor 46. The output end of the forward and reverse motor 46 passes through the top of the support frame 49 and is connected to the top of one of the rotating wheels 44 for transmission. By setting the transmission belt 45, the two slide blocks 42 can be driven to move in opposite directions. By setting two toggle rods 43, it can be ensured that the branches and leaves are definitely selected to move to both sides.

[0024] like Figure 4 As shown, positioning grooves 47 are provided on both side walls of the two guide holes 41, and positioning blocks 48 are fixedly connected on both sides of the two sliders 42. The outer surfaces of the four positioning blocks 48 are respectively slidably connected to the inside of the four positioning grooves 47. By setting the positioning blocks 48 and the positioning grooves 47, the sliders 42 can be positioned to improve stability.

[0025] like Figure 1 and Figure 2As shown, the feeding mechanism No. 1 2 includes a mounting frame 21, both sides of the mounting frame 21 are fixedly connected to the inside of the workbench 1, a feeding belt 22 is rotatably connected to the inside of the mounting frame 21, and a plurality of isolation plates 23 are fixedly connected to the outer surface of the feeding belt 22. The distance between two adjacent isolation plates 23 is the same as the diameter of the lychee. The top of the mounting frame 21 is fixedly connected to the bottom end of the guide frame 31. By setting the feeding belt 22, the material can be driven to move. By setting the isolation plate 23, the lychee can be isolated and limited to ensure that the branches and leaves are located in the upper half of the lychee, and the phenomenon of the lychee pressing the branches and leaves will not occur.

[0026] like Figure 1 and Figure 5 As shown, the feeding mechanism 5 includes a storage hopper 51, the bottom end of the storage hopper 51 is fixedly connected to the top of the workbench 1, and a No. 2 feeding mechanism 52 is arranged obliquely inside the storage hopper 51. The internal structure of the No. 2 feeding mechanism 52 is the same as the internal structure of the No. 1 feeding mechanism 2. By setting the storage hopper 51, materials can be stored, and by setting the No. 2 feeding mechanism 52, the lychees can be lifted and discharged, which is convenient for subsequent cutting.

[0027] like Figure 1 As shown, a material guide plate 6 is fixedly connected to the top of the workbench 1. The top of the material guide plate 6 is located directly below the No. 2 feeding mechanism 52, and the bottom of the material guide plate 6 is located directly above the No. 1 feeding mechanism 2. By setting the material guide plate 6, the material can be guided and buffered to prevent the lychees from falling directly into the No. 1 feeding mechanism 2 and generating a large impact force.

[0028] like Figure 1 and Figure 3 As shown, material guide holes 7 are provided on both sides of the guide rack 31 and at the position of the cutter 39, and material discharge troughs 8 are provided at the top of the workbench 1 and at the positions on both sides of the material guide rack 31. By providing the material guide holes 7, the branches and leaves can be guided to the designated position for easy cutting. By providing the material discharge trough 8, the cut branches and leaves can be guided so that they will not accumulate on the workbench 1.

[0029] The utility model provides a shearing device for lychee packaging, and the specific working principle is as follows:

[0030] The staff puts the lychees that need to be packaged into the storage hopper 51, and then starts the No. 1 feeding mechanism 2, the shearing mechanism 3, the digging mechanism 4 and the loading mechanism 5. The feeding belt 22 in the No. 2 feeding mechanism 52 rotates and, under the action of the isolation plate 23, a single lychee is clamped on the feeding belt 22. Under the lifting action of the No. 2 feeding mechanism 52, the lychees are transported from the storage hopper 51 to the guide plate 6. Under the action of gravity, the lychees slide between the isolation plates 23 of the No. 1 feeding mechanism 2. During the feeding process of the No. 1 feeding mechanism 2, the forward and reverse motor 46 drives one of the rotating wheels 44 to rotate, so that the slider 42 moves in the guide through hole 41 driven by the transmission belt 45, so that the digging rod 43 can guide the lychees that cannot pass through the guide frame 31 when passing through the No. 1 feeding mechanism 2. The branches and leaves are moved to both sides, and in the subsequent feeding process, the lychees enter the guide rack 31. During the entry process, the guide through holes 7 on the guide rack 31 guide the branches and leaves so that they enter just below the cutter 39. The driving motor 32 drives the No. 1 bevel gear 33 to rotate, so that the No. 2 bevel gear 35 meshing with the No. 1 bevel gear 33 drives the rotating shaft 34 to rotate. During the rotation of the rotating shaft 34, the adjusting rod 37 performs reciprocating up and down motion and pushes the cutter 39 fixedly connected to the driven plate 38 to reciprocate through the guide through hole 7, so that the lychee branches and leaves guided by the digging mechanism 4 and the guide rack 31 are cut by the cutter 39, and the cut lychees are collected uniformly under the drive of the No. 1 feeding mechanism 2, and the branches and leaves fall into the trash can for storage under the guidance of the discharge chute 8.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
