Description

Technical Field

[0001] This invention relates to the field of modern agricultural machinery and equipment technology, specifically to an adjustable-spacing transplanter for planting. Background Technology

[0002] Planting transplanters are specialized equipment used in modern agriculture to perform seedling transplanting operations, which can significantly improve operational efficiency in seedling transplanting.

[0003] In large-scale seedling transplanting operations, existing planting and transplanting machines inevitably encounter situations where seedlings are missed. Seedling growers typically replant these missed seedlings manually after the transplanting process. However, due to the large area of ​​the plots and the lack of any markings for the missed seedling locations, some areas are easily overlooked, leading to incomplete replanting. Incomplete replanting directly results in uneven crop planting density in the field, and the missed areas will also form "blank zones" due to the lack of seedling growth. This not only wastes arable land resources but also reduces yield per unit area. Furthermore, if these areas remain empty for a long time, they are prone to weed growth. Weeds not only compete with surrounding crops for water, nutrients, and sunlight but also increase the cost of subsequent field management. However, existing planting and transplanting machines generally lack the function of automatically marking missed seedlings, which further increases the difficulty of replanting later.

[0004] Therefore, we propose a new planting-based adjustable-spacing transplanter to address the problems mentioned in the background section. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable spacing transplanter for planting, which, by setting a marking mechanism, can automatically mark when seedlings are missing in the soil, thereby avoiding the situation of missing seedlings when manually replanting later, thus avoiding the appearance of "blank zones" in the planting area, ensuring the yield per unit area, and solving the problems mentioned in the background art.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-3 , Figures 5-7 and Figure 10As shown, the present invention provides a technical solution: a transplanting machine with adjustable spacing for planting, including a transplanting mechanism 1, the transplanting mechanism 1 including a vehicle body 101, a set of fixing blocks 105 fixed on the frame of the vehicle body 101, each fixing block 105 having a mounting seat 118 mounted on its top, a first rotating shaft 104 and a second rotating shaft 108 rotatably connected between the frame of the vehicle body 101 and the multiple mounting seats 118 respectively, multiple adjustable spacing seedling assemblies 102 pressed and fixed on the outer surface of the first rotating shaft 104, each seedling assembly 102 having a presser 103 fixed on its surface, a slide rail 106 fixed between the set of fixing blocks 105, multiple sliders 107 slidably connected on the slide rail 106, and a U-shaped block 119 fixed to the bottom of each slider 107, the U-shaped block 119 and a prepared hand-tightening screw being used to press and fix the slider 107 after its position has been moved, the outer surface of the second rotating shaft 108 is provided with Multiple seedling conveying assemblies 109 are provided, and a second rotating shaft 108 can drive all seedling conveying assemblies 109 to rotate. Each slider 107 is installed with each seedling conveying assembly 109. A first sprocket 110 is fixedly sleeved on the outer surface of the wheel axle of the vehicle body 101 and the outer surface of the second rotating shaft 108, and the two are connected by a first chain drive. A second sprocket 111 is fixedly sleeved on the outer surface of the second rotating shaft 108 and the outer surface of the first rotating shaft 104, and the two are connected by a second chain drive. An adjusting rod 112 is fixedly fixed on the surface of each seedling assembly 102. Each adjusting rod 112 is pressed and fixed on the frame of the vehicle body 101. A seedling support frame 113 is fixed on the frame of the vehicle body 101. A controller 114 and a driver 115 are installed on the top of the frame of the vehicle body 101, and a protective railing 116 is fixed on the top of the frame of the vehicle body 101. A battery 117 is placed inside the protective railing 116.

[0023] In this embodiment, during transplanting, the nurseryman first sits on the seat of the transplanter's vehicle 101, and then moves the traction device along the transplanting route. The traction device rotates the wheels and axles on the vehicle 101. The rotating axle then uses a first sprocket 110, a first chain, another first sprocket 110, all mounting seats 118, and all fixing blocks 105 connected to it to rotate a second axle 108. When the second axle 108 rotates, each seedling conveying assembly 109 guides the seedlings removed from the seedling holder 113 and placed into the corresponding seedling assembly 102, which is in a closed beak-like state. Meanwhile, the rotating second shaft 108 will cause all the seedling assemblies 102 to rotate through the frame of the vehicle body 101, the second chain, all the adjusting rods 112, the two second sprockets 111 and the first shaft 104. When the seedling assembly 102 starts to rotate, the duckbill on the seedling assembly 102, which is equipped with seedlings and is in a closed state, will first rotate, then fully insert into the soil, then open the duckbill and then rotate away, until it returns to the initial position, ready for the next transplanting cycle. At the same time, the moving compactor 103 will compact the soil on both sides of the seedlings transplanted into the soil. This process is repeated to continuously carry out the seedling transplanting operation, thereby improving the seedling transplanting efficiency.

[0024] Example 2: According to Figures 1-5 and Figures 8-11As shown, the transplanting mechanism 1 is equipped with a marking mechanism 2, which is used to mark areas in the soil where seedlings have not been transplanted. The marking mechanism 2 includes multiple storage bins 201, auxiliary blocks 223, and multiple cameras 225. Each storage bin 201 is equipped with a box cover 202 on its top, and an L-shaped frame 203 is fixed to the top of each box cover 202. Each L-shaped frame 203 has a first electric push rod 204, a mounting block 205, a moving block 210, and a rectangular plate 211 inside. Each mounting block 205 is equipped with a second electric push rod 206 on its top, and an auxiliary wheel 207 is installed at the telescopic end of each second electric push rod 206. Each L-shaped frame 203 is fixed with a top plate 214 on its top. Each moving block 210 and its corresponding top plate 214 are connected... A set of first springs 212 is fixed, and a set of second springs 215 is fixed to the inner wall of each storage bin 201. A push plate 216 sliding inside the storage bin 201 is fixed between the same end of each set of second springs 215. Multiple markers 218 are placed inside each storage bin 201. Multiple push blocks 219 move through the surface of the auxiliary block 223. Multiple motors 221 are installed in the top groove of the auxiliary block 223, and a transmission gear 220 is installed at the output end of each motor 221. Each first electric push rod 204 is installed on each L-shaped frame 203. Each mounting block 205 is slidably connected inside each L-shaped frame 203. The wheel surface of each auxiliary wheel 207 is respectively connected to the inner surface of each moving block 210. Each L-shaped frame 203 has a set of limiting blocks 208 fixed to its surface. A rubber pad 209 is adhered to the top of each limiting block 208. The bottom of each movable block 210 contacts the top of its corresponding rubber pad 209. Each movable block 210 is fixed to its corresponding rectangular plate 211. Each top plate 214 has a set of limiting rods 213 fixed to its bottom. The bottom end of each limiting rod 213 movably passes through the top of its corresponding movable block 210, the top of its corresponding rubber pad 209, and the top of its corresponding limiting block 208. The bottom end of each limiting rod 213 is fixed to the surface of its corresponding L-shaped frame 203. Each storage bin 201 has a fixed guide pipe 217 connected to its bottom. The top of each label 218 contacts its corresponding bin cover 201. The bottoms of the two parts are in contact. The push plate 216 is used to push the marker 218 to move its position inside the corresponding storage bin 201. The pushing end of each push block 219 moves through the outer wall of each storage bin 201. The motor 221, transmission gear 220 and push block 219 are used to push the marker 218 inside the storage bin 201 to move its position. The second electric push rod 206, auxiliary wheel 207, top plate 214 and moving block 210 are used to drive the rectangular plate 211 to move, while compressing the first spring 212. The rebound force of the first spring 212 and the moving block 210 make the rectangular plate 211 quickly reset, generating an impact force to quickly push the marker 218 out of the storage bin 201, fly out along the guide pipe 217, and insert it into the soil to mark its position.The first electric push rod 204, mounting block 205, and second electric push rod 206 are used to move the auxiliary wheel 207. A mounting frame 222 is fixed between the outer walls of multiple storage bins 201. The bottom of each rectangular plate 211 movably passes through the top of each bin cover 202. The auxiliary block 223 is fixed to the mounting frame 222. The outer wall of each storage bin 201 is fixed to the surface of the auxiliary block 223. A connecting plate 224 is fixed to the bottom of each storage bin 201. Each camera 225 is mounted on the bottom of each connecting plate 224. A magnetic strip 226 is fixedly embedded in the inner wall of each storage bin 201. The transplanting mechanism 1 includes a vehicle body 101. The mounting frame 222 is mounted on the frame of the vehicle body 101. A controller 114 and a driver 115 are mounted on the top of the frame of the vehicle body 101.

[0025] In this embodiment, when the transplanter starts transplanting seedlings, the controller 114 uses the camera 225 to determine the seedling transplanting status. If no seedlings are missed during transplanting, the controller 114 does not perform any action. If seedlings are missed, the controller 114 uses the driver 115 to move the second electric push rod 206 vertically upwards via the auxiliary wheel 207, L-shaped frame 203, and moving block 210. Simultaneously, the top plate 214, L-shaped frame 203, and moving block 210 move the corresponding... When spring 212 is compressed, and the moving block 210 moves upward to its limit, controller 114 uses driver 115, corresponding motor 221, and transmission gear 220 to move push block 219, reducing the squeezing force between markers 218. This allows the markers 218 to be pushed out next to be attracted by magnetic strip 226. Subsequently, controller 114 uses L-shaped frame 203, first electric push rod 204, mounting block 205, and second electric push rod 206 to separate auxiliary wheel 207 from moving block 210, thus allowing moving block 210 to quickly drive the rectangular... Plate 211 resets, and with a large impact force, the marker 218 held by magnetic strip 226 is quickly pushed out and precisely inserted into the soil for marking, guided by guide tube 217. When the first marker 218 is pushed out, the second marker 218 is moved to the position of the first marker 218, and then the moved marker 218 is pressed in place. At the same time, when rectangular plate 211 and moving block 210 reset to their original positions, auxiliary wheel 207 is also reset to its original position. When the first row of markers 218 has been pushed out, the push block is then... 219 is reset to its original position. After the push block 219 is reset to its original position, the remaining marker 218 inside the storage box 201 is pushed forward by the second spring 215 and the push plate 216 until it can no longer move. Then, the push block 219 is used to press the marker 218. When the position that needs to be marked is detected again, the second marker 218 will be pushed out again and placed on the soil to mark the position. This ensures that the missing seedlings can be quickly found and the replanting operation can be carried out in the later manual replanting, thus avoiding the appearance of "blank zones".

[0026] The overall effect and working principle of the mechanism are as follows: Before transplanting, the seedlings to be transplanted are placed flat on the seedling rack 113. Then, the controller 114 is turned on and the data of the missing seedling image is stored in its storage module. At the same time, the slider 107 moves on the slide rail 106 to adjust the distance between the two seedling conveying assemblies 109. After the seedling conveying assembly 109 has completed the position movement, it is fixed with U-shaped block 119 and prepared hand screws. At the same time, the distance between the two seedling assemblies 102 is adjusted. At this time, each seedling assembly 102 will drive the connected press 103 and adjusting rod 112 to move. After the seedling assembly 102 has completed the position movement, the seedling assembly 102 and adjusting rod 112 are fixed. After everything is ready, the transplanter body 101 is connected to the traction equipment. During transplanting, the nurseryman first sits on the seat of the transplanter's vehicle 101, then allows the traction device to move along the transplanting route. The moving traction device drives the vehicle 101 to move, causing its wheels and axles to rotate and shift position. Simultaneously, the rotating axles drive the connected first sprocket 110 to rotate. When the first sprocket 110 rotates, another first sprocket 110 connected via a first chain also moves, subsequently moving through all mounting seats 118 and all fixing blocks. 105. The second rotating shaft 108 is rotated. When the second rotating shaft 108 rotates, each conveyor cylinder on each seedling assembly 109 will rotate accordingly. At this time, the seedling grower takes some seedlings from the seedling rack 113 and places them into the rotating conveyor cylinders one by one. When the inside of the conveyor cylinder on the seedling assembly 109 connects with the inside of the guide cylinder on it, the seedlings inside the conveyor cylinder will be guided to the closed beak of the corresponding seedling assembly 102. At the same time, the rotating second rotating shaft 108 will pass through the vehicle body 101. The frame, second chain, all adjusting levers 112, and two second sprockets 111 cause the first shaft 104 to rotate. This rotation of the first shaft 104 drives all the seedling assemblies 102 to rotate. When the seedling assembly 102 begins to rotate, the beak on the seedling assembly 102 descends. Specifically, the beak lifting frame on the seedling assembly 102 is driven by its cam, causing the closed beak to move downwards. At this time, the tip of the closed beak, containing the seedling, inserts into the soil as the seedling assembly 102 rotates. When closed... Once the seedling assembly 102 is fully inserted into the soil and the seedling beak containing the seedlings is in the correct position, the seedling beak will open and leave the soil. The seedling (with substrate block) in the seedling beak will remain in the soil. The upward-lifting seedling beak will close under the spring force of the seedling assembly 102 and return to the initial position, ready for the next transplanting cycle. At this time, the compactor 103, which moves with the seedling assembly 102, will compact the soil on both sides of the transplanted seedling. This process can be repeated to continuously perform seedling transplanting operations. If seedlings are missed, when the transplanter begins transplanting seedlings, the controller 114 activates all cameras 225. Each camera 225 collects image data along the transplanting route and transmits it to the controller 114. Upon receiving the image data, the controller 114 compares it with its internally stored data to determine the seedling transplanting status. If no seedlings are missed, the controller 114 will not activate the motor 221, the first electric push rod 204, or the second electric push rod 206 via the driver 115. If seedlings are missed, the controller 114 will activate the second electric push rod 206 on the corresponding transplanting route via the driver 115. 206 will move the rectangular plate 211 vertically upward via the auxiliary wheel 207, L-shaped frame 203, and moving block 210. Simultaneously, the moving block 210 will compress the corresponding first spring 212 using the top plate 214, L-shaped frame 203, and moving block 210. When the moving block 210 reaches its maximum height, the controller 114 will move the push block 219 via the driver 115, corresponding motor 221, and transmission gear 220 to reduce the squeezing force between the markers 218. At this point, the markers 218 that need to be released will be attracted by the magnetic strip 226. Subsequently, the controller 114 will use the L-shaped frame 203, first electric push rod 204, mounting block 205, and second electric push rod 206 to separate the auxiliary wheel 207 from the moving block 210. After wheel 207 separates from moving block 210, the rebound force of first spring 212 will cause moving block 210 to drive rectangular plate 211 to quickly reset. The large impact force of the reset rectangular plate 211 will cause the marker 218 attracted by magnetic strip 226 to be quickly pushed out. The pushed-out marker 218 will then be guided by guide tube 217 and accurately inserted into the soil for marking. When the first marker 218 is discharged, controller 114 will immediately use motor 221, push block 219, transmission gear 220 and auxiliary block 223 to move the marker 218 inside storage box 201, that is, to move the second marker 218 to the position of the first marker 218, and squeeze the moved marker 218. Rubber pad 209 and limit block 208 are used to accurately reset the moving block 210 back to its original position. After the rectangular plate 211 and the moving block 210 are reset to their original positions, the auxiliary wheel 207 is reset to its original position. After the first row of markers 218 are pushed out, the push block 219 is reset to its original position. After the push block 219 is reset to its original position, the remaining markers 218 inside the storage box 201 will be pushed forward by the second spring 215 and the push plate 216. After the remaining markers 218 have moved, the motor 221 will move the push block 219 again to press the markers 218. When the position that needs to be marked is detected again, the controller 114 will repeat the above operation steps through the cooperation of the above components to mark the position.

Therefore, the control method and wiring layout will not be explained in detail here.
