Description

Technical Field

[0001] This invention relates to the field of transplanter technology, and in particular to a high-efficiency perforating transplanter for crop planting. Background Technology

[0002] Seedling transplanting technology can significantly improve crop survival rate and growth quality. Its applications are widespread; most crops can be grown through transplanting, including medicinal herbs such as *Spatholobus suberectus*, tobacco, and vegetables. Most transplanting machines on the market can only perform one function: punching holes or transplanting seedlings. While some machines can perform both, they often operate in a dual-station mode where punching comes first and transplanting comes later. To ensure the seedling is placed precisely into the pre-drilled holes, the machine's forward speed must be sufficiently uniform. Therefore, existing punching and transplanting machines are highly dependent on the uniformity of the machine's speed. However, in open fields, uneven surfaces make it difficult to maintain this uniformity, resulting in insufficient seedling placement accuracy and requiring subsequent manual intervention. Therefore, developing an integrated punching and transplanting machine that does not rely on uniform movement speed and can achieve precise seedling placement is essential. Summary of the Invention

Detailed Implementation

[0034] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. Example

[0035] A high-efficiency punching and transplanting machine for crop planting, such as Figure 1-6 As shown, the system includes a base plate 1; a hollow cup motor 2 is mounted on the base plate 1; a collar 3 is mounted on the inner wall of the rotor of the hollow cup motor 2; an outer cylinder 4 is mounted inside the collar 3; several grooves are spaced apart on the inner wall of the collar 3; several protrusions 5 that mate with the grooves are mounted on the outer wall of the outer cylinder 4; an openable and closable cone 6 is mounted at the bottom of the outer cylinder 4; the cone 6 is composed of two half-cone cylinders, and the upper ends of the two half-cone cylinders are hinged to the outer cylinder 4; a return spring 19 is connected between the outer walls of the two half-cone cylinders; the outer cylinder 4 is rotatably connected to the moving plate 8 through a bidirectional thrust bearing 17; a reciprocating drive assembly 9 for supporting and driving the moving plate 8 to move up and down is mounted on the upper part of the base plate 1.

[0036] An inner cylinder 7 is movably installed inside the inner cavity of the outer cylinder 4; limit cylinders 11 are installed on the upper ends of both sides of the movable plate 8; a slider 16 is slidably installed inside the limit cylinder 11; the lower end of the slide rod 12 is connected to the slider 16, and the upper end is connected to the mounting plate 15 fixedly installed on the side wall of the inner cylinder 7; a spring 13 is sleeved on the slide rod 12, and its upper and lower ends are respectively connected to the lower end of the mounting plate 15 and the upper end of the limit cylinder 11; several limit rods 14 are also installed on the bottom plate 1. A gap is left between the inner cylinder 7 and the outer cylinder 4.

[0037] The aforementioned high-efficiency perforating transplanter for crop planting uses a hollow cup motor 2 to drive the outer cylinder 4 to rotate. A bidirectional thrust bearing 17 connects the outer cylinder 4 and the moving plate 8 for relative rotation. The outer cylinder 4 is supported and installed via the moving plate 8, and a reciprocating drive assembly 9 drives the moving plate 8 and the outer cylinder 4 to move up and down reciprocally. During operation, the reciprocating drive assembly 9 pushes the moving plate 8 and the outer cylinder 4 downwards, activating the hollow cup motor 2 to drive the outer cylinder 4 to rotate. The outer cylinder 4 rotates while moving downwards to perform the perforation operation. During this descent, the inner cylinder 7 moves downwards along with the outer cylinder 4 under the action of the spring 13, the slider 16, and the limiting cylinder 11. After the drilling is completed, the hollow cup motor 2 stops rotating or rotates in the opposite direction. The reciprocating drive assembly 9 pushes the moving plate 8 and the outer cylinder 4 to move upward. Under the action of the spring 13, the inner cylinder 7 moves upward with the outer cylinder 4 until the top of the mounting plate 15 contacts the limiting rod 14. The limiting rod 14 limits the upward movement of the inner cylinder 7, and the inner cylinder 7 can no longer move upward. However, the outer cylinder 4 continues to move upward under the action of the reciprocating drive assembly 9, so that the inner cylinder 7 moves downward relative to the outer cylinder 4. The lower edge of the inner cylinder 7 will press down against the inner wall of the cone 6. Under the pushing action of the inner cylinder 7, the two halves of the cone 6 rotate around the hinge axis until they open up so that the seedling can fall smoothly.

[0038] Specifically, the outer wall of the cone 6 is fitted with a spiral blade 18; a guide post 10 is mounted on the base plate 1; and a guide sleeve 21, which is slidably connected to the guide post 10, is connected to the movable plate 8 on one side. The spiral blade 18 can improve the soil breaking capacity and also remove excess soil. The guide post 10 and the guide sleeve 21 work together to provide guidance.

[0039] Specifically, the reciprocating drive assembly 9 includes a servo motor 901 mounted on the base plate 1, a lead screw 902 rotatably mounted on the base plate 1, a nut block 904 mounted on the moving plate 8, and a transmission assembly 903 for connecting the lead screw 902 and the servo motor 901; the transmission assembly 903 is a meshing gear set or a synchronous belt assembly. The servo motor 901 drives the lead screw 902 to rotate through the transmission assembly 903, thereby driving the moving plate 8 to move up and down. In another embodiment, the reciprocating drive assembly 9 is an electric telescopic rod, a hydraulic cylinder, or a pneumatic cylinder. Using a hydraulic cylinder requires installing a hydraulic station on the base plate 1; using a pneumatic cylinder requires installing a pneumatic station on the base plate 1.

[0040] Specifically, a protective cover is installed on the base plate 1; the protective cover is placed on the outside of the transmission assembly 903.

[0041] Specifically, several support rods 22 are installed on the upper part of the base plate 1; a placement plate 23 is installed on the top of the support rods 22. During operation, the seedlings to be transplanted are placed on the placement plate 23, making it convenient to place them one by one into the inner cylinder 7.

[0042] Specifically, a fixed seat 24 is installed on the upper end of the base plate 1, and the operator can sit on the fixed seat 24 when working.

[0043] Specifically, a traveling wheel 25 is mounted on the lower part of the base plate 1, and a battery 26 is mounted on the base plate 1. In another embodiment, a generator is also mounted on the base plate 1. The present application can be towed forward using a tractor, or a drive assembly capable of driving the traveling wheel 25 to rotate can be mounted on the axle of the traveling wheel 25. Example

[0044] A high-efficiency perforating transplanter for crop planting has been added with components 27, 28, 29, and 20, such as... Figure 7-11 As shown, the rest of the structure is the same as in Example 1.

[0045] Specifically, a seedling feeding assembly 29 is installed on the upper part of the base plate 1; the seedling feeding assembly 29 includes a support column 2901 fixed to the base plate 1; a crossbar 2902 is fixed to the top of the support column 2901; a rotating shaft 2903 is rotatably installed at both ends of the crossbar 2902; sprockets are installed at the upper and lower parts of the two rotating shafts 2903; a transmission chain is installed between the two sprockets at the upper and lower parts; several openable seedling feeding cones 2904 are evenly spaced on the outer side of the transmission chain; each seedling feeding cone 2904 is formed by two halves hinged together; the two halves of the seedling feeding cone... Both sides of the cone are provided with flat surfaces, and threaded holes are opened on the flat surfaces; a second return spring is installed between the two half-planting cones; the side wall of one half-planting cone is connected to the transmission chain through a "U"-shaped bracket 2908, and the side wall of the other half-planting cone is rotatably mounted with a roller 2907 through a protruding column; a discharge sleeve 2905 is provided on the crossbar 2902; a discharge plate is fixedly connected to one side of the discharge sleeve 2905; an inclined transition plate 2906 is connected to one side of the discharge plate; a strip groove is opened on one side wall of the discharge sleeve 2905.

[0046] Before operation, adjust the position of the unloading sleeve 2905 so that it is directly above the inner cylinder 7. Place the seedlings to be transplanted in each seedling cone 2904. During operation, drive the rotating shaft 2903 to rotate, the transmission chain moves, and the transmission chain drives the seedling cone 2904 to rotate cyclically. As the seedling cone 2904 moves, when the roller 2907 installed on it climbs up the transition plate 2096 to the unloading plate, it drives the half seedling cone on the side with the roller 2907 to open, and the seedlings placed in the seedling cone 2904 fall into the inner cylinder 7 below. Compared with embodiment 1, the added seedling component 29 allows the operator to place the seedlings into the seedling cone 2904, and the seedlings in the seedling cone 2904 will automatically fall into the inner cylinder 7 one by one. This reduces the skill requirements for the operator and avoids seedling leakage or damage caused by inaccurate manual seedling placement.

[0047] Specifically, the crossbar 2902 includes an inner bar and an outer bar sleeved outside the inner bar; both the inner and outer bars have fixed seats on their upper walls; and bolts are installed between the two fixed seats. By rotating the bolts, the effective length of the inner and outer bar combination can be adjusted, thereby adjusting the tension of the drive chain and facilitating the disassembly and assembly of the drive chain.

[0048] Specifically, a drive assembly for driving the rotating shaft 2903 to rotate is mounted on the crossbar 2902; the drive assembly includes a drive motor mounted on the crossbar 2902; the output shaft of the drive motor and one of the rotating shafts 2903 are equipped with a set of meshing gears 35.

[0049] Specifically, the bottom of the support rod 22 is mounted on the crossbar 2902.

[0050] Specifically, a water tank 27 is installed on the base plate 1; one end of a water pipe is connected to the water tank 27, and the other end is equipped with a spray nozzle 28. A control valve is installed on the water pipe. By installing the water tank 27, watering or fertilization can be carried out during the transplanting process.

[0051] Specifically, the inner wall of the inner cylinder 7 is equipped with several buffer plates 20. Each buffer plate 20 is bent, with one side connected to the inner wall of the inner cylinder 7 and the other side suspended, using the bend as a boundary. The buffer plates 20 are made of flexible material, preferably foam or cardboard. When a seedling with soil falls and impacts the buffer plate 20, the buffer plate 20 can rotate around its bend, thus providing cushioning. The buffer plates 20 can slow down the descent speed of the seedling, preventing it from being damaged due to excessive speed.

[0052] Specifically, the contact edges of the two halves of the cone 6 are provided with interlocking parts. When one half of the cone 6 is rotated under force, the other half can be driven to rotate through the interlocking parts.

[0053] Working principle of the invention:

[0054] This application can be moved forward using a traction machine, or a drive assembly capable of driving the walking wheels 25 to rotate can be installed on the axle of the walking wheels 25. Before operation, adjust the position of the unloading sleeve 2905 so that it is directly above the inner cylinder 7. Place the seedlings to be transplanted in each seedling cone 2904. During operation, turn on the drive assembly that drives the hollow cup motor 2, the servo motor 901, and the drive shaft 2903 to rotate. The drive shaft 2903 rotates, the transmission chain moves, and the transmission chain drives the seedling cone 2904 to rotate cyclically. As the seedling cone 2904 moves, when the roller 2907 installed on it climbs up the transition plate 2096 to the unloading plate, it causes the half seedling cone on the side with the roller 2907 to open, and the seedling placed in the seedling cone 2904 falls into the inner cylinder 7 below. The rotation of the hollow cup motor 2 drives the outer cylinder 4 to rotate; the outer cylinder 4 and the moving plate 8 are connected to each other through the bidirectional thrust bearing 17; the outer cylinder 4 is supported and installed by the moving plate 8, and the moving plate 8 and the outer cylinder 4 can be driven to move up and down reciprocally by the reciprocating drive assembly 9. During operation, the reciprocating drive assembly 9 pushes the moving plate 8 and the outer cylinder 4 to move downward, the hollow cup motor 2 is turned on, and the outer cylinder 4 is driven to rotate. The outer cylinder 4 moves downward while rotating, performing the drilling operation. During the descent, the inner cylinder 7 moves downward together with the outer cylinder 4 under the action of the spring 13, the slider 16, and the limiting cylinder 11. After the drilling is completed, the hollow cup motor 2 stops rotating or rotates in the opposite direction. The reciprocating drive assembly 9 pushes the moving plate 8 and the outer cylinder 4 to move upward. Under the action of the spring 13, the inner cylinder 7 moves upward with the outer cylinder 4 until the top of the mounting plate 15 contacts the limiting rod 14. The limiting rod 14 limits the upward movement of the inner cylinder 7, and the inner cylinder 7 can no longer move upward. However, the outer cylinder 4 continues to move upward under the action of the reciprocating drive assembly 9, so that the inner cylinder 7 moves downward relative to the outer cylinder 4. The lower edge of the inner cylinder 7 will press down against the inner wall of the cone 6. Under the pushing action of the inner cylinder 7, the two halves of the cone 6 rotate around the hinge axis until they open up so that the seedling can fall smoothly.

[0055] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
