Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of modern agricultural equipment, in particular to an adjustable spacing transplanter for planting. BACKGROUND

[0002] The transplanting machine is a professional device for seedling transplanting in modern agriculture, which can greatly improve the work efficiency in seedling transplanting.

[0003] In the large-area land seedling transplanting operation of the existing transplanting machine, it is inevitable that there will be seedling missing. The seedling grower usually manually replants after the transplanting operation is completed. However, due to the large area of the land and the absence of any mark on the missing seedling position, some missing seedling points are easily missed, which leads to incomplete replanting. Incomplete replanting directly leads to uneven planting density of crops in the field, and the missing seedling area will form a "blank zone" due to the absence of seedlings. This not only wastes farmland resources, but also reduces the yield per unit area. In addition, if the missing seedling area is left vacant for a long time, weeds are likely to grow, which not only competes with the surrounding crops for water, nutrients and light, but also increases the cost of later field management. However, the existing transplanting machine generally lacks the function of automatically marking missing seedlings, which further increases the difficulty of later replanting.

The second electric push rod 206, the auxiliary wheel 207, the top plate 214 and the 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 are used to quickly reset the rectangular plate 211 to generate an impact force, which quickly pushes the marking tag 218 out of the inside of the storage box 201, flies along the flow guide pipe 217 and is inserted into the soil to mark the position.The first electric push rod 204, the mounting block 205 and the second electric push rod 206 are used for moving the auxiliary wheel 207, the mounting frame 222 is fixed between the outer walls of the plurality of storage boxes 201, the bottom of each rectangular plate 211 is movably penetrated through the top of each cover plate 202 respectively, the auxiliary block 223 is fixed on the mounting frame 222, the outer wall of each storage box 201 is fixed with the surface of the auxiliary block 223, the bottom of each storage box 201 is fixed with the connecting plate 224, each camera 225 is additionally arranged at the bottom of each connecting plate 224 respectively, the inner wall of each storage box 201 is fixedly embedded with the magnetic stripe 226, and the transplanting mechanism 1 comprises a vehicle body 101.

[0037] In the embodiment, when the transplanter starts to transplant seedlings, the controller 114 judges the seedling transplanting condition by using the camera 225, when the seedling transplanting does not appear the seedling missing condition, the controller 114 does not make any action, when the seedling transplanting appears the seedling missing condition, the controller 114 makes the second electric push rod 206 move vertically upward through the auxiliary wheel 207, the L-shaped frame 203 and the moving block 210 by using the driver 115, simultaneously makes the corresponding first spring 212 be compressed by using the top plate 214, the L-shaped frame 203 and the moving block 210, when the moving block 210 is moved to the position that cannot be moved, the controller 114 makes the push block 219 move by using the driver 115, the corresponding motor 221 and the transmission gear 220, reduces the extrusion force between the mark tags 218, makes the mark tag 218 that is pushed out next be attracted by the magnetic stripe 226, then the controller 114 makes the auxiliary wheel 207 and the moving block 210 separate by using the L-shaped frame 203, the first electric push rod 204, the mounting block 205 and the second electric push rod 206, that is, makes the moving block 210 drive the rectangular plate 211 to reset quickly, makes the mark tag 218 attracted by the magnetic stripe 226 be pushed out quickly with a large impact force, and the mark tag 218 is guided by the draft tube 217 and is accurately inserted into the soil to mark, when the first mark tag 218 is discharged, the second mark tag 218 is moved to the position of the first mark tag 218, then the mark tag 218 after moving is extruded, when the rectangular plate 211 and the moving block 210 reset to the original position, the auxiliary wheel 207 is reset to the original position, when all the mark tags 218 in the first row are pushed out, the push block 219 is reset to the original position, after the push block 219 resets to the original position, the remaining mark tags 218 in the storage box 201 are pushed forward by using the second spring 215 and the push plate 216 until the position that cannot be moved, then the mark tags 218 are extruded by using the push block 219, when the position that needs to be marked is detected again, the second mark tag 218 is pushed out again and marks the position on the soil, so that the artificial seedling supplementing can quickly find the position of the missing seedlings and perform the seedling supplementing operation, thereby avoiding the “blank zone”.

[0038] The effect and working principle of the whole mechanism are as follows: before transplanting, the seedlings to be transplanted are placed on the seedling supporting frame 113, the controller 114 is opened, the data of the seedling missing picture is stored in the storage module, the distance between the two seedling conveying assemblies 109 is adjusted by moving the slider 107 on the slide rail 106, after the seedling conveying assembly 109 completes the position movement, the U-shaped block 119 and the prepared hand screw are used for fixing, the distance between the two seedling assemblies 102 is adjusted again, at this time, each seedling assembly 102 moves to drive the connected tamper 103 and the adjusting rod 112 to move, after the seedling assembly 102 completes the position movement, the seedling assembly 102 and the adjusting rod 112 are fixed, and after all preparations are completed, the vehicle body 101 of the transplanting machine is connected with the traction equipment;

[0039] When transplanting, the seedling grower first sits on the seat of the vehicle body 101 of the transplanting machine, and then moves the traction device along the transplanting route. At this time, the moving traction device will drive the vehicle body 101 to move, and when the vehicle body 101 moves, the wheels and the rotating shafts thereon will also rotate and move in position. At the same time, the rotating shafts will also drive the first sprocket 110 connected thereto to rotate. When the first sprocket 110 rotates, the other first sprocket 110 connected by the first chain will also move, and then the second rotating shaft 108 is driven to rotate through all the mounting seats 118 and all the fixing blocks 105. When the second rotating shaft 108 rotates, each conveying cylinder on each seedling conveying assembly 109 will also rotate. At this time, the seedling grower takes some seedlings from the seedling support 113 and puts them into the rotating conveying cylinder in sequence. When the inside of the conveying cylinder is connected with the inside of the guide cylinder, the seedlings in the conveying cylinder will be guided into the duckbill in the closed state of the seedling assembly 102. At the same time, the rotating second rotating shaft 108 drives the first rotating shaft 104 to rotate through the frame of the vehicle body 101, the second chain, all the adjusting rods 112 and the two second sprockets 111. At this time, the rotating first rotating shaft 104 drives all the seedling assemblies 102 to rotate. When the seedling assembly 102 starts to rotate, the duckbill on the seedling assembly 102 will descend, i.e. the duckbill lifting frame on the seedling assembly 102 is driven by the cam thereon to move the duckbill in the closed state downward. At this time, the duckbill tip with seedlings in the closed state will be inserted into the soil with the rotation of the seedling assembly 102. When the duckbill in the closed state with seedlings is completely inserted into the soil, and the seedling assembly 102 continues to rotate, the duckbill inserted into the soil will open and leave the soil at this time. At this time, the seedlings (with substrate blocks) in the duckbill will remain in the soil, and the upwardly lifted duckbill will be closed under the action of the spring force on the seedling assembly 102 to return to the initial position, ready for the next planting cycle. At this time, the roller 103 moving with the seedling assembly 102 will compact the soil on both sides of the seedlings transplanted into the soil. In this way, the seedling transplanting operation can be carried out continuously;

[0040] When the seedling transplanting machine starts to transplant seedlings, the controller 114 starts all the cameras 225 at this time, and each camera 225 collects image data on the transplanting route and transmits it to the controller 114. After receiving the image data, the controller 114 compares it with the data stored in its internal data to determine the seedling transplanting situation. When there is no seedling transplanting missing, the controller 114 does not start the motor 221, the first electric push rod 204 and the second electric push rod 206 through the driver 115. When there is seedling transplanting missing, the controller 114 starts the second electric push rod 206 on the corresponding transplanting route through the driver 115. The second electric push rod 206 that is started at this time moves the rectangular plate 211 vertically upward through the auxiliary wheel 207, the L-shaped frame 203 and the moving block 210. At the same time, the moving block 210 moves the corresponding first spring 212 through the top plate 214, the L-shaped frame 203 and the moving block 210 to be compressed. When the moving block 210 is moved to the position where it cannot move, the controller 114 moves the push block 219 through the corresponding motor 221 and the transmission gear 220 to reduce the extrusion force between the marker tags 218. At this time, the marker tags 218 that need to be released are attracted by the magnetic strip 226. Subsequently, the controller 114 separates the auxiliary wheel 207 from the moving block 210 through the L-shaped frame 203, the first electric push rod 204, the mounting block 205 and the second electric push rod 206. After the auxiliary wheel 207 is separated from the moving block 210, the rebound force of the first spring 212 makes the moving block 210 drive the rectangular plate 211 to quickly reset. The large impact force brought by the reset rectangular plate 211 makes the marker tags 218 attracted by the magnetic strip 226 be quickly pushed out. Subsequently, the pushed-out marker tags 218 are guided by the flow guide pipe 217 and accurately inserted into the soil to mark. When the first marker tag 218 is discharged, the controller 114 immediately moves the marker tags 218 in the storage box 201 through the motor 221, the push block 219, the transmission gear 220 and the auxiliary block 223, that is, moves the second marker tag 218 to the position of the first marker tag 218, and extrudes the moved marker tag 218. At the same time, the rubber pad 209 and the limiting block 208 make the moving block 210 accurately reset to the original position. When the rectangular plate 211 and the moving block 210 reset to the original position, the auxiliary wheel 207 resets to the original position. After the first row of marker tags 218 are pushed out, the push block 219 resets to the original position. After the push block 219 resets to the original position, the remaining marker tags 218 in the storage box 201 are pushed forward by the second spring 215 and the push plate 216. After the remaining marker tags 218 complete the movement, the motor 221 moves the push block 219 again to extrude the marker tags 218. When the position that needs to be marked is detected again, the controller 114 repeats the above operation steps through the cooperation of the above components to mark the position.

Meanwhile, the wiring diagram of the controller 114, the driver 115, the battery 117, the first electric push rod 204, the second electric push rod 206, the motor 221 and the camera 225 is the technology known in the art, and the working principle is the disclosed technology.
