Description

Technical Field

[0001] The invention relates to the technical field of seedling cutting machines, and in particular to a self-propelled intelligent blanket seedling cutting machine based on discless seedlings. Background Art

[0002] The seedling transplanting planting method is widely used in large-scale production of grain, vegetables, fruits, flowers and other agricultural fields to facilitate centralized management of seedlings, ensure real-time transplanting according to the season, increase crop yield and quality, and improve economic benefits. It is of great significance to the development of my country's primary industry.

[0003] At present, seedling raising technology can be divided into seedling tray raising method and tray-free seedling raising method. In the process of seedling tray raising, seed treatment, tray division, sowing, and soil covering are required. Before transplanting, work such as lifting the seedlings and separating the seedling trays is also required. In the process of tray-free seedling raising, only the processed seeds need to be sown in the seedling raising field or a specific seedling raising area, and they can be directly transplanted after being cut into blanket-like seedlings. Compared with the two seedling raising technologies, the tray-free seedling raising method has a simple procedure, reduces labor intensity, and reduces equipment purchase costs. Not using seedling trays reduces the cost of seedling raising and avoids environmental pollution problems caused by seedling trays. In the process of tray-free seedling raising, the seedlings are cut into blankets, mostly manually cut according to the required size specifications, which is time-consuming and labor-intensive, and the cutting effect of the seedlings cannot be guaranteed to be consistent.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Reference Figure 1-14 The present invention provides a self-propelled intelligent blanket seedling cutting machine based on discless seedlings, comprising:

[0041] In this device, the fixed rail assembly is fixed on the ground, the moving rail assembly slides on the fixed rail assembly, the frame walks on the moving rail assembly through the first walking mechanism. When the electric push rod 16 extends or contracts, the cutter floating frame 13 can rotate on the frame 1.

The cutter transmission shaft 20 drives the cutter pressing plate 22 and the cutter 21 to rotate. The self-locking mechanism 2 can lock the cutter floating frame 13. When cutting seedlings is required, through the first walking mechanism, the frame 1 moves on the moving rail assembly to make the cutter 21 located above the starting position. The electric push rod 16 extends to make the cutter floating frame 13 rotate and rise to the highest position, and then the electric push rod 16 contracts to make the cutter floating frame 13 press down to the set cutting depth. During this process, the self-locking state of the self-locking device 2 is released, and the cutter 21 enters the seedlings. The second motor 4 drives the cutter 21 to rotate, and the first walking mechanism makes the frame 1 move on the moving rail assembly, and the cutter 21 can cut the seedlings, dividing the seedlings on the ground into long strips. When the frame 1 walks to the other end on the moving rail assembly, the cutting of the seedlings is completed. Then the first walking mechanism drives the frame 1 to return to the initial position, and the moving rail assembly moves on the fixed rail assembly.

Two of the rollers 52 are arranged to roll on the first fixed rail 37, and the other two rollers 52 are arranged to roll on the second fixed rail 38.

[0045] The I-shaped frame 51 moves on the first fixed rail 37 and the second fixed rail 38 through the rollers 52. The I-shaped frame 51 can be pulled to move through the push-pull rod 36. The limit piece 42 is used to abut against the moving rail assembly to facilitate the moving rail assembly to determine the initial position on the second fixed rail 38.

[0047] The two movable rails 41, the first connecting rod and the second connecting rod form a frame, and the movable rail positioning concave groove plate 31 is slidably set on the fixed rail 2 38, so as to prevent the two movable rails 41 from detaching from the fixed rail 2 38 and the fixed rail 3 40. Through the walking mechanism 2, the movable rails 41 can move on the fixed rail 2 38 and the fixed rail 3 40.

[0049] The motor three 24 drives the travel pulley drive shaft 26 to rotate through the sprocket transmission group five 25, and the travel pulley drive shaft 26 drives the rear travel wheel three 28 to rotate through the sprocket transmission group six 27. The travel pulley drive shaft 26 drives the front travel wheel three 30 to rotate through the sprocket transmission group seven 29. The rear travel wheel three 28 and the front travel wheel three 30 rotate at the same time, so that the movable track 41 can move on the fixed track two 38 and the fixed track three 40.

[0050] A further optimized solution is that the walking mechanism 1 includes a motor 3, which is fixedly connected to the frame 1, and the frame 1 is rotatably connected to the rear transmission shaft 6 and the front transmission shaft, and the two ends of the rear rotating shaft 6 are rotatably connected to the rear walking wheel 1 7 and the rear walking wheel 2 8, and the two ends of the front transmission shaft are rotatably connected to the front walking wheel 1 9 and the front walking wheel 2 11, and the front transmission shaft and the rear transmission shaft 6 are connected through the sprocket transmission group 2 10 and the sprocket transmission group 3 12, and the sprocket transmission group 2 10 and the sprocket transmission group 3 12 are located on both sides of the frame 1, and the motor 3 is connected to the rear transmission shaft 6 through the sprocket transmission group 1 5, and the front walking wheel 1 9 and the front walking wheel 2 11 are respectively slidably set on two moving rails 41, and the rear walking wheel 1 7 and the rear walking wheel 2 8 are respectively slidably set on two moving rails 41.

[0051] The first motor 3 drives the rear transmission shaft 6 to rotate through the first sprocket drive group 5.

At the same time, the rear transmission shaft 6 drives the front transmission shaft to rotate through the second sprocket drive group 10 and the third sprocket drive group 12.

The first front traveling wheel 9, the second front traveling wheel 11, the first rear traveling wheel 7 and the second rear traveling wheel 8 can move on the moving track 41.

[0052] In a further optimized solution, the steering mechanism includes a base 32 and a support cross beam 33. Two positioning support plates 35 are fixedly connected to both ends of the support cross beam 33. Two gyro-shaped support columns 34 are fixedly connected to the bottom surface of the support cross beam 33. A circular thin plate 53 is fixedly connected to the base 32. An annular guide groove is provided on the circular thin plate 53. The two gyro-shaped support columns 34 are located in the annular guide groove.

[0053] The steering mechanism is used to turn the moving rail assembly and the cutting assembly to the adjacent seedling area. When using the steering mechanism, the distance determining mechanism needs to be taken out first, and then the base 32 is placed between the first fixed rail 37 and the second fixed rail 38, so that the two moving tracks 41 are located within the two positioning support plates 35. At the same time, the moving track 41 is also located on the support cross beam 33. The positioning support plate 35 is in contact with the moving track 41. At this time, the moving rail positioning concave groove plate 31 is separated from the second fixed rail 38. The distal end of the moving track 41 is lifted to make the moving track 41 rotate. At this time, the two gyro-shaped support columns 34 rotate in the annular guide groove, and a 180° rotation can complete the steering. The positioning support plate 35 is N-shaped.

[0054] In a further optimized solution, a first induction probe 46 is fixedly connected to the cutter floating frame 13. A first induction magnet 47 and a second induction magnet 48 are fixedly connected to the moving track 41. A second induction probe 49 is fixedly connected to the rear U-shaped frame 39. A third induction magnet 50 is fixedly connected to the I-shaped frame 51.

[0055] When the rack 1 moves on the moving track 41, when the first induction probe 46 on the side of the cutter floating frame 13 senses the first induction magnet 47 on the moving rail, the cutter 21 reaches the specified depth position, the electric push rod 16 stops extending and stops working, and the first motor 3 and the second motor 4 start to work. At this time, the cutting work starts; when the second induction probe 49 on the rear U-shaped frame 39 senses the third induction magnet 50 on the I-shaped frame 51, the third motor 24 stops working, and the moving track 41 stops traveling on the second fixed rail 38 and the third fixed rail 40, and the next round of cutting work is started from this position.

[0056] For a further optimized solution, a cutter guard 18 is fixedly connected to the cutter shaft support plate 17. The self-locking mechanism 2 includes a spring 43, a spring clip 44 and a hanging pin 45. A first bracket is fixedly connected to the frame 1, and the hanging pin 45 is fixedly connected to the first bracket. A second bracket is fixedly connected to the cutter floating frame 13. A pin shaft is rotatably connected to the second bracket, the spring clip 44 is rotatably connected to the pin shaft, one end of the spring 43 is fixedly connected to the second bracket, the other end of the spring 43 is fixedly connected to the spring clip 44, and the spring clip 44 is hung on the hanging pin 45.

[0057] The cutter guard 18 is used to protect the cutter 21.

[0058] The usage method of this device: After installing this device in the seedling area to be cut, adjust the distance determining mechanism so that the limit piece 42 fits one of the moving tracks 41. Start the electric push rod 16. The electric push rod 16 raises the cutter floating frame 13 and the cutter 21 to the highest position and then presses them down to the set cutting depth. During this process, the spring 43 changes from a stretched state to a compressed state, and the hook and the hanging part on the spring clip 44 are bounced open by the external force generated by the spring compression and separated from the hanging pin 45, and the self-locking state of the self-locking device 2 is released. Subsequently, the cutter floating frame 13 is pressed down by the electric push rod 16 and drives the cutter 21 to move downward. When the induction probe one 46 on the side of the cutter floating frame 13 senses the induction magnet one 47 on the moving rail, the cutter 21 reaches the specified depth position, and the electric push rod 16 stops extending and stops working;

[0059] The first motor 3 and the second motor 4 start to work. The first motor 3 drives the rear drive shaft 6 to rotate through the first sprocket transmission group 5. The rear drive shaft 6 drives the rear traveling wheel one 7 and the rear traveling wheel two 8 to rotate. At the same time, the rear drive shaft 6 drives the front drive shaft to rotate through the second sprocket transmission group 10 and the third sprocket transmission group 12. The front drive shaft drives the front traveling wheel one 9 and the front traveling wheel two 11 to rotate, so that the frame 1 moves on the moving track 41. The second motor 4 drives the cutter drive shaft 20 to rotate through the fourth sprocket transmission group 19. The cutter drive shaft 20 drives the cutter pressure plate 22 and the cutter 21 to rotate, and the cutter 21 cuts the seedlings;

[0060] After the current seedlings are cut, the third motor 24 is started. The third motor 24 drives the traveling pulley drive shaft 26 to rotate through the fifth sprocket transmission group 25. The traveling pulley drive shaft 26 drives the rear traveling wheel three 28 to rotate through the sixth sprocket transmission group 27. The traveling pulley drive shaft 26 drives the front traveling wheel three 30 to rotate through the seventh sprocket transmission group 29. The rear traveling wheel three 28 and the front traveling wheel three 30 rotate simultaneously, so that the moving track 41 moves on the fixed track two 38 and the fixed track three 40. When the induction probe two 49 on the rear U-shaped frame 39 senses the induction magnet three 50 on the I-shaped frame 51, the third motor 24 stops working, and the moving track 41 stops traveling on the fixed track two 38 and the fixed track three 40, and the next round of cutting work is started from this position.

[0061] When it is necessary to cut the seedling field on the other side of the fixed rail 1 - 37, pull the moving rail handle to pull out the push - pull limit device 36 and place it into the steering device. Put the base 32 between the fixed rail 1 - 37 and the fixed rail 2 - 38, so that the two moving rails 41 are located within the two positioning support plates 35. At the same time, the moving rails 41 are also located on the support cross - beam 33. The positioning support plates 35 are in contact with the moving rails 41. At this time, the moving - rail positioning concave - groove plate 31 is separated from the fixed rail 2 - 38. Lift the distal - end moving rail 41 to make the moving rail 41 rotate. At this time, the two gyro - type support columns 34 rotate in the annular guide groove, and a 180° rotation can complete the steering.

[0062] In the present invention, the self - locking device is used to lock the cutter floating frame 13, prevent the cutter floating frame 13 from rotating when it is not working, and can bear part of the gravity of the cutter when the device stops running and automatically spring open when the device is running. By the settings of the induction probe 1 - 46, the induction probe 2 - 49, the induction magnet 1 - 47, the induction magnet 2 - 48, and the induction magnet 3 - 50, the functions of automatically stopping the knife - lifting and automatically changing rows at the end of cutting are realized, achieving the purpose of automated and efficient cutting and intelligent operation. Through the combined - type track, which is used for the traveling operation of the track cutting machine, the combined - type track adopts a two - layer structure (fixed rail and moving rail) superimposed, supplemented with a push - pull limit device. During the cutting operation of the carpet - like seedlings, the cutting accuracy is improved, and there is no need for manual alignment, ensuring the uniformity of the carpet - like seedling specifications. At the same time, the combined - type track raises the operation height of the cutting machine, avoiding the phenomenon of seedling rolling damage during the operation. The steering device is used for the track cutting machine, enabling the cutting machine to turn with a small turning space, simple and labor - saving operation, reducing the number of times of seedling rolling caused by changing the operation direction, and to a certain extent solving the problem that seedlings are easily damaged during commutation.

[0063] From Figure 1 it can be seen that there was originally an upper shielding cover installed on the frame 1. In Figure 2 and Figure 3 for clearly showing the internal structure, the upper shielding cover was removed. The upper shielding cover only has a protective function.
