[0029] like Figure 1-8 As shown, a pepper transplanter can realize fully automated transplanting of pepper seedlings, greatly improving the transplanting efficiency. Specifically, the present invention includes a frame 1 and a seedling delivery mechanism 2, a seedling taking mechanism 3, a seedling separation mechanism 4 and a seedling planting mechanism 5 arranged on the frame 1. The frame 1 is welded by square steel, angle steel, etc. to form a rectangular parallelepiped structure.

[0030] The overall layout of each mechanism of the present invention is as follows: Figure 1 and 2 As shown in the figure, the seedling delivery mechanism 2 is located on one side of the top of the frame 1, the seedling picking mechanism 3 is located on one side of the seedling delivery mechanism 2, the seedling separation mechanism 4 is located below one side of the seedling picking mechanism 3, and the seedling transplanting mechanism 5 is located below the seedling separation mechanism 4. The seedlings to be transplanted can be transferred between the seedling delivery mechanism 2, the seedling picking mechanism 3, the seedling separation mechanism 4 and the seedling transplanting mechanism 5 in sequence.

[0031] The seedling delivery mechanism 2 of the present invention is used to transport the seedling plug tray 16 so that the seedling retrieval mechanism 3 can grab the seedlings on the plug tray 16 row by row. The seedling retrieval mechanism 3 cooperates with the seedling delivery mechanism 2 to complete the grabbing of the seedlings on the plug tray 16 and can transfer the seedlings to the subsequent seedling separation mechanism 4. The seedling separation mechanism 4 is mainly used to expand the spacing of the densely spaced seedlings grabbed on the plug tray 16 so that it can meet the actual seedling spacing required for transplanting. The seedling transplanting mechanism 5, as the name implies, is used to transplant the seedlings separated by the seedling separation mechanism 4 into the plant hole to complete the transplanting.

[0032] The seedling delivery mechanism 2 may be in the form of a conveyor belt, or in the form of a chain sprocket set, or in other structural forms capable of stepping and delivering the plug tray 16. Figure 5 As shown in the figure, a chain sprocket group is disclosed, the seedling delivery mechanism 2 includes two chain plates 11 connected to the frame 1 through a seedling delivery bracket 99 and arranged side by side, two axles 12 are arranged between the two ends of the chain plate 11, sprockets 13 are installed on the two axles 12, and a conveying chain 14 is adapted on the sprocket 13. A seedling delivery motor 15 is arranged on the chain plate 11 corresponding to one axle 12, and the seedling delivery motor 15 is connected to the axle 12. The seedling delivery mechanism 2 also includes a plug tray 16, and the edges of both sides of the plug tray 16 are placed on the conveying chain 14.

[0033] When in use, the seedling delivery motor 15 rotates, driving the wheel shaft 12 to rotate, and then driving the sprocket 13 and the conveying chain 14 to move, so that the hole tray 16 is gradually conveyed forward. The frequency and distance of the step-by-step conveying can be coordinated with the seedling taking mechanism 3. In the process of conveying, in order to further ensure stability, the conveying deviation caused by the swing of the hole tray 16 is avoided. A better approach of the present invention can also be that the chain links of the conveying chain 14 are provided with a number of extension pins for stabilizing the hole tray 16. The extension pin can be a vertical pin arranged on the chain link, which is a group of two by two, and multiple groups are arranged. The distance between the two extension pins in each group is equivalent to the length of the hole tray 16, which just realizes the limit of the two ends of the hole tray 16. Of course, it can also be a cross pin, which is also a group of two by two, and multiple groups are arranged. When in use, the cross pin is stuck between the hole grooves of the hole tray 16, and a limit can also be formed. The extension pin can be arranged on the conveying chain 14 on both sides, or it can be arranged on one side, but generally speaking, it is best to set it together on both sides.

[0034] After the plug tray 16 is transported to the right place, in order to facilitate the grabbing and transporting of the seedlings on the plug tray 16 to the next process, and in order to minimize the volume of the overall equipment of the present invention, the seedling removal mechanism 3 of the present invention adopts a fan-type design, such as Figure 3-4As shown in the figure, the seedling taking mechanism includes a vertically arranged seedling taking cylinder 6, the lower end of which is connected to a seedling taking motor 7 mounted on a frame 1. A windmill-shaped seedling taking turntable 9 composed of a plurality of blades 8 is provided at the upper end of the seedling taking cylinder 6. A contoured gripper 10 for grabbing the seedlings on the seedling delivery mechanism 2 is provided below each of the blades 8.

[0035] When in use, after the seedling delivery mechanism 2 delivers a row of the plug tray 16 to a position (just below a certain blade 8), the seedling cylinder 6 drives the seedling turntable 9 to descend, so that the contour gripper 10 set on the corresponding blade 8 descends to achieve the grabbing of a row of seedlings. After the grabbing is completed, the seedling cylinder 6 drives the seedling turntable 9 to rise; then the seedling motor 7 rotates, and the blade 8 grabbing the seedlings is rotated to the working position corresponding to the seedling separation mechanism 4, and then descends. The contour gripper 10 is released to release the seedlings, and one blade 8 completes a working cycle. Usually, the number of blades 8 is 4, but it can also be more or less.

[0036] The contoured gripper 10 of the present invention is mainly used to grab and put down the seedlings on the plug tray 16. A preferred implementation structure thereof can be as follows: Figure 3 and 4 As shown in , it includes two mounting plates 17 arranged at the bottom of the blade 8, and two rotating shafts 18 are arranged side by side between the two mounting plates 17. As shown in the figure, the main part of the rotating shaft 18 is a square shaft, and circular rotating sections are arranged at both ends. In this way, since the main part is a square shaft, the mounting surface is more reliable and it is more conducive to installing a clamp thereon. One end of the two rotating shafts 18 is provided with a fan gear 19 that meshes with each other. Multiple groups of seedling cards 20 are arranged in pairs on the two rotating shafts 18. The number of the seedling cards 20 is the same as the number of each row of seedling holes on the hole tray 16, and the spacing of the seedling cards 20 is adapted to the spacing of the seedling holes on the hole tray 16. The rotating shaft 18 is driven by a gripper motor 21 arranged on the mounting plate 17.

[0037] When working, Figure 4 As shown in the figure, the gripper motor 21 rotates, driving the rotating shaft 18 to rotate. One of the two rotating shafts 18 is a driving shaft and the other is a driven shaft (i.e., the left side in the figure is the driven shaft and the right side is the driving shaft. The driving shaft rotates clockwise and the driven shaft rotates counterclockwise). Driven by the fan gear 19, the two rotating shafts 18 can hold or release the seedlings on the plug tray 16 in the state shown in the figure, that is, to achieve opening and closing grasping and releasing. The contour gripper 10 grabs at the position corresponding to the seedling delivery mechanism 2 and releases at the position corresponding to the seedling separation mechanism 4.

[0038] like Figure 6As shown in , the seedling separation mechanism 4 of the present invention includes a slide rail 22 arranged on the frame 1 and extending along the length direction of the frame 1, and a plurality of sliders 23 cooperating with the slide rail 22 are arranged on the guide slide rail 22. The number of sliders 23 corresponds to the number of a row of seedlings grasped by the contour gripper 10, that is, the number of seedlings in a row of the plug tray 16. A seedling separation cylinder 24 is fixedly arranged on the front side of each of the sliders 23. The seedling separation cylinder 24 is used to receive the seedlings put down by the contour gripper 10. However, since the seedling spacing on the contour gripper 10 is the relatively small seedling spacing on the plug tray 16, and the seedling spacing of the subsequent seedling transplanting mechanism 5 is a larger spacing, the seedling separation mechanism can adjust the spacing of the seedling separation cylinder 24, usually with the last seedling separation cylinder 24 as a fixed point, and the other seedling separation cylinders 24 move, thereby adjusting. (That is to say, the last slider 23 is actually fixed in form, and it does not move, as a reference point for positioning, while the rest are synchronously telescoped to achieve the scaling of the spacing)

[0039] In order to achieve the above functions, Figure 6 As shown in , the seedling separation mechanism 4 of the present invention also includes a seedling separation motor 25, a connecting rod 26, a crank 27, and a plurality of scissor-type telescopic arms 28, the sliders 23 are connected by the telescopic arms 28, the seedling separation motor 25 is installed on the frame 1, and the output end is connected to one end of the crank 27, and the other end of the crank 27 is connected to one end of the connecting rod 26. The other end of the connecting rod 26 is connected to a slider 23 at the end through the telescopic arm 28.

[0040] When in use, the seedling separation motor 25 drives the crank 27 to rotate, and the crank 27 drives the connecting rod 26 to move, thereby driving the telescopic arm 28 to open and close. The sliders 23 are driven to move synchronously, so that the seedling separation cylinders 24 on the sliders 23 can be closed or separated in an orderly manner. It should be noted that the spacing adjustment range of the seedling separation cylinders 24 can cover the spacing of the seedling taking cards 20 on the contour gripper 10, as well as the seedling spacing of the seedling transplanting mechanism 5. That is to say, when the seedling separation cylinder 24 is adjusted to the most compact state, it can achieve the spacing of the contour gripper 10. And in the most separated state, it can also meet the spacing requirements of the seedling transplanting mechanism 5.

[0041] In order to achieve control over the seedlings in the seedling separation tube 24 , a flap 29 is provided at the lower end of the seedling separation tube 24 . The flap 29 can be driven to open and close, thereby achieving opening and closing control over the lower end of the seedling separation tube 24 .

[0042] The flap 29 can be opened and closed by direct active drive, for example: the flap 29 is driven by a pneumatic push rod 30 fixedly arranged on the seedling separation tube 24. In the case of such direct active drive, the connection form can be that one side of the flap 29 is hinged with the seedling separation tube 24, and a small convex warp is arranged on the other side of the hinge axis relative to the flap 29 body, and the pneumatic push rod 30 is arranged on the cylinder body of the seedling separation tube 24, and the output end is downward, and is hinged with the small convex warp through a short connecting rod. The short connecting rod is driven to rise by the rising and retracting of the output end of the pneumatic push rod 30, and the short connecting rod pulls the small convex warp on the flap 29, thereby driving the flap 29 to open. The output end of the pneumatic push rod 30 is pressed down and extended, and the flap 29 is driven to close.

[0043] The flap 29 can also be opened and closed by indirect passive driving. For example, the pneumatic push rod 30 is eliminated in the aforementioned manner, and instead the cross bar 51 is fixedly arranged on the seedling transplanting bracket 31, and is positioned opposite to and above the small protrusion 50; when the cross bar 51 contacts the small protrusion 50 on the flap 29, the cross bar 51 forms a closed lock on the flap 29 by squeezing the small protrusion 50; when the cross bar 51 is disengaged from the small protrusion 50 on the flap 29, the flap 29 is in a free state and can be opened by the gravity of the seedlings falling in the seedling separation tube 24.

[0044] The lower opening of the seedling separation tube 24 is preferably an oblique cut, and the flip cover 29 is adapted to the oblique cut. Like this, the seedling separation tube 24 can open the flip cover 29 at the position connected with the seedling planting device 33 upper ends of the seedling planting mechanism 5, and does not affect the normal opening and closing of the flip cover 29.

[0045] About seedling transplanting mechanism 5 of the present invention, Figure 7 and 8 As shown in , the seedling transplanting mechanism 5 includes a seedling transplanting bracket 31, which is connected to the frame 1 through a ball screw pair 32 and can be lifted and lowered relative to the frame 1 under the drive of the ball screw pair 32. The specific structure of the ball screw pair 32 is relatively conventional and will not be repeated in the present invention.

[0046] The seedling support 31 is provided with a plurality of seedling inserters 33. The seedling inserters 33 include a funnel-shaped seedling receiving bucket 34 and a soil inserting cone composed of a plurality of soil inserting pieces 35 arranged below the seedling receiving bucket 34. The upper portion of each soil inserting piece 35 is connected to a pusher block 37 through a connecting arm 36, and is hinged to the seedling receiving bucket 34 at the connecting arm 36. The pusher block 37 can push the soil inserting pieces 35 constituting the soil inserting cone to open when squeezing the soil downward.

[0047] The working principle of the seedling transplanting mechanism 5 is as follows: the ball screw pair 32 drives the seedling transplanting bracket 31 to rise, so that the seedling transplanter 33 is opposite to the lower end of the seedling separation tube, the cover of the seedling separation tube is opened, and the seedlings fall into the seedling receiving bucket 34. Then the ball screw pair 32 drives the seedling transplanting bracket 31 to descend, and the seedling transplanter 33 first contacts the soil with the soil insertion cone and inserts a hole in the soil, and then as the seedling transplanter 33 continues to descend, the pusher block 37 begins to contact the soil, and as the contact continues, the pusher block 37 drives the soil insertion piece 35 to open through the connecting arm 36, and the seedlings fall into the hole. After being lifted, the soil insertion cone of the seedling transplanter 33 is naturally closed, and the next working cycle is entered.
