[0035] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0036] Example 1:

[0037] This embodiment provides a linkage transmission mechanism, such as... Figures 1-14 As shown, it includes a linkage frame 1, four linkage assemblies 2, and two connecting rods 3. The linkage frame 1 supports the four linkage assemblies 2.

[0038] Four linkage assemblies 2 are symmetrically connected to the left and right sides of the linkage frame 1. The two linkage assemblies 2 on the same side are connected to both ends of the connecting rod 3. The two ends of the connecting rod 3 are subjected to balanced forces, keeping the connecting rod 3 horizontal. The four linkage assemblies 2 can drive the connecting rods 3 on the left and right sides to reciprocate and move simultaneously while maintaining a horizontal position. The two connecting rods 3 on the left and right sides move synchronously.

[0039] In this embodiment, the linkage transmission mechanism, through the relative arrangement of the linkage assembly 2, enables the up-and-down lifting and dragging movement of the connecting rod 3. When applied to the transmission of fruit, it can realize the picking and putting of fruit, making it more flexible, expanding its application range, and meeting different fruit transmission needs.

[0040] As a preferred embodiment, such as Figures 1-3 As shown in the schematic diagram on the right side of the linkage transmission mechanism, the linkage assembly 2 includes a first link 21, a second link 22, a third link 23, and a fourth link 24. One end of the first link 21 and the third link 23 are rotatably connected to both ends of the fourth link 24, respectively. The other end of the first link 21 is connected to a drive member 11, which can be a motor. One end of the second link 22 is rotatably connected to the middle section of the fourth link 24, and the other end is rotatably connected to a connecting rod 3. The second link 22 and the third link 23 are connected to the upper side of the fourth link 24. When the drive member 11 drives the first link 21 to rotate around its pivot, it drives the second link 22 to reciprocate and lift the connecting rod 3. The first links 21 of the two sets of linkage assemblies 2 rotate synchronously and are arranged in parallel. The length of the fourth link 24 > the length of the third link 23 > the length of the first link 21 > the length of the second link 22.

[0041] Specifically, two drive shafts 12 are installed within the linkage frame 1, positioned one behind the other. The two ends of the front drive shaft 12 are connected to the two front left and right first connecting rods 21, and the two ends of the rear drive shaft 12 are connected to the two rear left and right first connecting rods 21. A drive motor drives the front drive shaft to rotate, and the front drive shaft drives the rear drive shaft to rotate via a belt or sprocket, thus causing the four linkage assemblies 2 to rotate synchronously.

[0042] The linkage assembly 2 in this embodiment has a stable structure, which keeps the second linkage 22 in a vertical state, thereby keeping the connecting rod 3 in a horizontal state and enabling the connecting rod 3 to reciprocate in an elliptical motion trajectory.

[0043] like Figures 1-3 As shown, in Figure 1 The first connecting rod 21 rotates to the vertically downward position, and the connecting rod 3 is at its lowest point; Figure 2The first link 21 rotates to the horizontal forward position, and the connecting rod 3 is in the middle position; Figure 3 The first link 21 rotates to the vertically upward position, and the connecting rod 3 is at its highest point.

[0044] As a preferred embodiment, such as Figures 1-3 As shown, the fourth link 24 includes a first segment 221, a second segment 222, and a third segment 223. The first segment 221 and the third segment 223 are respectively connected to the two ends of the second segment 222. The length of the second segment 222 is greater than the lengths of the first segment 221 and the third segment 223. The angle between the first segment 221 and the second segment 222 is equal in angle and opposite in direction to the angle between the third segment 223 and the second segment 222. The first segment 221 and the third segment 223 are arranged parallel to each other. The first link 21 is connected to the end of the first segment 221 furthest from the second segment 222, and the third link 23 is connected to the end of the third segment 223 furthest from the second segment 222. The second link 22 is connected to the middle of the second segment 222. The angle between the first segment 221 and the second segment 222 is an obtuse angle opening downwards. The lengths of the first segment 221 and the third segment 223 are equal, and the length of the second segment 222 is twice the length of either the first segment 221 or the third segment 223.

[0045] The shape of the fourth link 24 in this embodiment makes the link assembly 2 operate more smoothly, avoids mutual interference, and is more reasonable in design.

[0046] This embodiment also provides a continuous core removal machine, including the aforementioned linkage transmission mechanism, as well as a bracket 42 assembly and a core removal frame 5. The bracket assembly 4 is buoyantly connected to two connecting rods 3, which support the bracket assembly 4. The two connecting rods 3 are located on the left and right sides of the bracket assembly 4, respectively.

[0047] like Figure 10 and Figure 11 As shown, the linkage transmission mechanism can lift and move the bracket assembly 4 from the first position 51 and the second position 52 to the second position 52 and the third position 53 while keeping the bracket assembly 4 horizontal. Figure 10 and Figure 11 As shown in the schematic diagram on the left side of the continuous core removal machine, the bracket assembly 4 rotates counterclockwise on the vertical plane under the action of the linkage transmission mechanism.

[0048] As a preferred embodiment, such as Figures 4-7 As shown, the bracket assembly 4 includes a support frame 41 and multiple brackets 42 arranged along the front-to-back direction on the support frame 41. The support frame 41 supports and connects the multiple brackets 42, enabling the bracket assembly 4 to form a whole and operate simultaneously. Multiple brackets 42 can hold more fruit, improving work efficiency. Specifically, 2, 3, 4, or 5 brackets 42 can be provided.

[0049] Multiple trays 42 are connected parallel to each other on the support frame 41 at intervals. Multiple moving channels 54 are provided on the pitting frame for the trays 42 to pass through, with each tray 42 positioned in one of the moving channels 54. The moving channels 54 are arranged along the front-to-back direction to guide the lifting and dragging movement of the trays 42. The pitting frame is located on the outside of the connecting rod frame 1. The upper surface of the tray 42 has a corrugated structure, which is arranged along the length of the moving channel 54. The corrugated structure is used to hold the fruit, and the fruit is placed separately at the troughs of the corrugated structure, ensuring that each fruit is placed separately.

[0050] Specifically, such as Figure 4 and Figure 5 As shown, multiple vertically arranged guide rods 31 are provided on the upper side of the connecting rod 3, and multiple guide holes 55 corresponding to the guide rods 31 are provided at the bottom end of the support frame 41. The bracket assembly 4 is connected to the guide rods 31 through the guide holes 55. Pads 32, which can be made of acrylic, are provided at both the front and rear ends of the connecting rod 3 to cushion the support frame 41 and prevent damage to the bottom of the support frame 41 due to long-term friction and collision. Two connecting blocks are provided in the middle of the connecting rod 3, and each connecting block is provided with three guide rods 31. The guide rods 31 can be metal rods with a certain degree of elasticity.

[0051] like Figure 6 and Figure 7 As shown, a slide rail 13 is provided on the upper side of the connecting rod frame 1, which is arranged in the front-to-back direction. A pulley 43 is provided on the lower side of the support frame 41, and the pulley 43 is slidably mounted on the slide rail 13. The pulley 43 is connected to the bottom of the support rod, which is connected to the middle position inside the kernel removal frame 5 and is erected.

[0052] When the continuous core removal machine in this embodiment is working, such as Figure 7 As shown, during the process of connecting rod 3 moving to the highest point, connecting rod assembly 2 lifts bracket assembly 4 through connecting rod 3, at which time pulley 43 leaves slide rail 13 and rises above it; as Figure 6 As shown, when the connecting rod 3 moves to the lowest point, the connecting rod assembly 2 drives the connecting rod 3 to move downward. When the support frame 41 descends to the point where the pulley 43 contacts the slide rail 13, the bracket assembly 4 stops descending and moves only back and forth with the connecting rod 3 under the action of the guide rod 31. The pulley 43 slides on the slide rail 13, and the support frame 41 moves upward relative to the guide rod 31.

[0053] As a preferred embodiment, such as Figure 5 and Figure 8 , Figure 9As shown, vertical shafts 56 are respectively provided on the left and right sides of the pitting frame 5, and horizontal shafts 411 are respectively provided on the left and right sides of the support frame 41. The horizontal shafts 411 are arranged in the front-to-back direction. A vertical slider 57 is slidably mounted on the vertical shaft 56, and a horizontal slider 412 is slidably mounted on the horizontal shaft 411. The horizontal slider 412 is connected to the vertical slider 57, specifically, the horizontal slider 412 and the vertical slider 57 are connected by a connecting plate. The horizontal shaft 411 and the vertical shaft 56 are arranged perpendicularly to each other. Specifically, two sets of guide mechanisms for the horizontal shafts 411 and the vertical shafts 56 are provided on the same side of the continuous pitting machine.

[0054] In this embodiment, during the lifting and moving process, the bracket assembly 4 operates accurately and smoothly through the guiding effect of the horizontal axis 411 and the vertical axis 56, so as to ensure the precise movement of the bracket 42.

[0055] As a preferred embodiment, the continuous pitting machine of this embodiment further includes a feeding mechanism 6, a posture adjustment mechanism 7, and a pitting mechanism 8, such as... Figure 10 and Figure 11 As shown, the feeding mechanism 6, the attitude adjustment mechanism 7, and the core removal mechanism 8 are arranged sequentially from front to back along the moving channel 54, and the feeding mechanism 6, the attitude adjustment mechanism 7, and the core removal mechanism 8 form a first position 51, a second position 52, and a third position 53 respectively relative to the moving channel 54. The feeding mechanism 6, the attitude adjustment mechanism 7, and the core removal mechanism 8 are mounted on the core removal frame 5, which provides support and connection for the feeding mechanism 6, the attitude adjustment mechanism 7, and the core removal mechanism 8.

[0056] In this embodiment, the bracket assembly 4 can transfer the fruit lifting and holding mechanism 6 and the posture adjustment mechanism 7 to the pitting mechanism 8 and the posture adjustment mechanism 7, thereby realizing the transfer of fruit between different steps.

[0057] As a preferred embodiment, such as Figure 10 and Figure 11 As shown, the feeding mechanism 6 includes a hopper 61 and a chute 62. The bottom outlet of the hopper 61 is connected to the upper end of the chute 62. The chute 62 is inclined downwards and its bottom end is connected to the moving channel 54. The end of the chute 62 connected to the moving channel 54 is the first position 51. The hopper 61 is used to store fruits to be pitted. The width of the chute 62 is adapted to the size of individual fruits, and the fruits roll down in the chute 62.

[0058] like Figure 12 As shown, the chute 62 includes two baffles 621. The longitudinal section of the baffles 621 is L-shaped. The two baffles 621 are arranged opposite each other on both sides of the moving channel 54. When the bracket 42 moves upward from the moving channel 54, it lifts the fruit located in the chute 62 and distributes it to different troughs of the corrugated structure.

[0059] As a preferred embodiment, such as Figure 13 As shown, the attitude adjustment mechanism 7 includes multiple adjusting members correspondingly arranged on both sides of the moving channel 54. Each adjusting member includes a first support tooth 71, a second support tooth 72, and a third support tooth 73. The first and second support teeth 71 and 72 are positioned close to the moving channel 54 and arranged one behind the other. The third support tooth 73 is located on the side of the first and second support teeth 71 and 72 away from the moving channel 54. The first and second support teeth 71 and 72 are symmetrically arranged about the centerline of the third support tooth 73. An adjustment cavity 74 for receiving the removed material is formed between the first, second, and third support teeth 71 and 72. The first, second, and third support teeth 71 and 72 are respectively inclined upwards towards the side away from the adjustment cavity 74.

[0060] In this embodiment, after the bracket 42 descends from the moving channel 54 at the posture adjustment mechanism 7, the fruit on the bracket 42 is blocked in the adjustment cavity 74. The adjustment cavity 74 makes the fruit lie flat, so that the fruit stem is on the left or right side, so as to facilitate the next step of pitting.

[0061] As a preferred embodiment, such as Figure 14 As shown, the pitting mechanism 8 includes a support member 82, a pusher member, and a pitting rod 81. The pitting rod 81 is arranged along the left-right direction of the frame and connected to the power output end of the pusher member, which can be a cylinder. The support member 82 is disposed within a moving channel 54. Multiple guide holes 55 are provided on the frame on both sides of the moving channel 54. The pusher member can drive the pitting rod 81 through the guide holes 55 and squeeze the pitted material placed on the support member 82 to remove the pit. Figure 14 As shown, the support member 82 is a corrugated sawtooth support plate with perforations 821 at the troughs for the core removal rod 81 to pass through.

[0062] In this embodiment, the bracket 42 lifts the fruit adjusted at the posture adjustment mechanism 7 and moves it to the third position 53. After the bracket 42 descends from the moving channel 54 at the pitting mechanism 8, the fruit on the bracket 42 is blocked on the support member 82 and the fruit stem is corresponding to the perforation 821. The pusher drives the pitting rod 81 to pass through the perforation 821 to squeeze the fruit placed on the support member 82 to remove the pit, thereby completing the pitting operation.

[0063] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
