Detailed implementation manners

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] First embodiment The present invention provides an automated potato breeding seedbed. Refer to Figure 1, including a seedbed frame 100, a conveying mechanism 200, a positioning mechanism 300, a spraying mechanism 400, and a net bed 500. When the breeding seedbed is needed, after sowing, the staff place the net bed 500 at a specific position, grab it through the conveying mechanism 200, and control the seedbed to move horizontally into the interior of the seedbed frame 100. Inside the seedbed frame 100, according to the position where it needs to be placed, and control the conveying mechanism 200 to reach the predetermined position, that is, when it reaches directly above a certain set of positioning mechanisms 300, pick up the seedbed through the positioning mechanism 300, and regularly spray water or nutrient solution on the net bed 500 through the spraying mechanism 400. After the set cultivation time, take out the net bed 500 in sequence.

[0020] Among them, a plurality of transparent windows are arranged at intervals on the seedling raising frame 100 for absorbing solar energy.

[0021] See Figure 2 and Figure 3 , the conveying mechanism 200 is hoisted on the top of the seedbed frame 100, and the conveying mechanism 200 controls the net bed 500 to move horizontally.

[0022] Specifically, the conveying mechanism 200 includes a loading platform 210, a horizontal conveying component 220, and a clamping component 230.

[0023] The loading platform 210 includes a fixed platform 211 and a lifting platform 212. Among them, the fixed platform 211 is fixed at one end of the seedbed frame 100 in the length direction. An elevating cylinder 213 is arranged between the lifting platform 212 and the fixed platform 211. Through the elevating cylinder 213, the lifting platform 212 can be controlled to rise to a specific height or descend to a specific height. During use, the position of the loading platform 210 is relatively fixed with respect to the seedbed frame 100. Therefore, when the horizontal conveying component 220 grabs the net bed 500 from the loading platform 210, the grabbing position can be relatively fixed, and the stability and safety of the net bed 500 can be ensured during the grabbing and moving process.

[0024] A positioning shallow groove 2121 is arranged on the upper side of the lifting platform 212 for placing the net bed 500; among them, the size of the positioning shallow groove 2121 needs to just meet the requirement of placing the net bed 500. After placing the net bed 500, the net bed 500 will not move relatively in the horizontal direction. Specifically, when the net bed 500 needs to be placed, the elevating cylinder 213 controls the lifting platform 212 to lower the height. At this time, it is convenient for the staff to operate. After the placement is completed, the elevating cylinder 213 controls the lifting platform 212 to rise. After rising, the horizontal conveying component 220 grabs the net bed 500. Since the net bed 500 is positioned by the positioning shallow groove 2121, during the grabbing process, the grabbing position is relatively fixed, ensuring the accuracy of subsequent movement.

[0025] The horizontal conveying assembly 220 includes a carriage 221, a driving lead screw 222, and a driving motor 223. Among them, the carriage 221 is slidably installed below the top of the seedbed frame 100, and the carriage 221 slides along the length direction of the seedbed frame 100. Specifically, when installing, guide rails 224 can be arranged at intervals on the top of the seedbed frame 100 to support and limit the carriage 221, so that the carriage 221 can slide horizontally along the guide rails 224. During the horizontal sliding process, it can be ensured that the mesh bed 500 has no displacement in the vertical direction.

[0026] On one side of the top of the seedbed frame 100 close to the carriage 221, support blocks 225 are fixedly installed. Two groups of support blocks 225 are fixedly arranged at intervals and are respectively located at both ends of the seedbed frame 100 in the length direction. Both ends of the driving lead screw 222 are respectively rotatably connected to the two support blocks 225. A linkage block 226 is threadedly connected to the driving lead screw 222, and the linkage block 226 is fixedly connected to the carriage 221. Among them, it should be noted that during installation, it is necessary to ensure that the driving lead screw 222 and the guide rail 224 are parallel to each other in the length direction. When the driving lead screw 222 rotates, it will rotate relative to the linkage block 226, and then drive the carriage 221 to move along the guide rail 224.

[0027] The driving motor 223 is fixedly installed on the seedbed frame 100. The output shaft of the driving motor 223 is connected to the driving lead screw 222, and the driving motor 223 drives the driving lead screw 222 to rotate forward or backward. Among them, the connection method between the output shaft of the driving motor 223 and the driving lead screw 222 can be through gear transmission connection, or through structures such as chains or belts for connection, as long as it can realize the driving motor 223 to control the driving lead screw 222 to rotate forward or backward.

[0028] The clamping assembly 230 is installed on the carriage 221. The mesh bed 500 of the feeding platform 210 is clamped and fixed through the clamping assembly 230.

[0029] The carriage 221 is U-shaped, and both vertical sides of the carriage 221 are perpendicular to the length direction of the driving lead screw 222. The clamping assemblies 230 are respectively installed on the vertical sides of the carriage 221 and are arranged horizontally at intervals in multiple numbers. Specifically, during transportation, when the carriage 221 moves directly above the lifting platform 212 (initial position), the lifting platform 212 can complete the rising action. During this process, when the lifting platform 212 rises, the mesh bed 500 can be located inside the carriage 221, and then the clamping assemblies 230 at both ends can complete the clamping work on the mesh bed 500. Specifically, when designing, a contact switch can be set at the initial position to control whether the lifting platform 212 can rise, that is, when the carriage 221 abuts against this contact switch, the lifting platform 212 can be controlled to rise. By setting the contact switch, it can be avoided that the lifting platform 212 has already risen when the carriage 221 has not moved to the initial position.

[0030] The clamping component 230 includes a mounting frame 231, a butting block 232, and a second telescopic device 233; the mounting frame 231 is fixed to the outside of the carriage 221, and a guiding opening 2311 is formed in the mounting frame 231, and the guiding opening 2311 penetrates through the carriage 221. The butting block 232 is slidably mounted in the guiding opening 2311, and the outer side wall of the butting block 232 is in virtual contact with the inner side wall of the guiding opening 2311. The butting block 232 can slide along the guiding opening 2311. At the same time, when the butting block 232 butts against the net bed 500, the guiding opening 2311 can support the butting block 232, improving the stability and service life. The second telescopic device 233 is fixedly mounted on the mounting frame 231 and is located at one end away from the carriage 221; the second telescopic device 233 can be a cylinder, a lead screw structure, an oil cylinder, as long as it can complete linear movement. The telescopic end of the second telescopic device 233 is located in the guiding opening 2311 and is fixedly connected to the butting block 232; when the second telescopic device 233 expands and contracts, it can control the butting block 232 to partially extend out of the guiding opening 2311 or completely enter the guiding opening 2311. When controlling the butting block 232 to partially extend out of the guiding opening 2311, the butting block 232 will butt against the net bed 500. Through the cooperation of multiple groups of clamping components 230, the two parallel side edges of the net bed 500 are butted simultaneously, and the clamping and fixing work of the net bed 500 can be completed. After the net bed 500 is clamped, the lifting cylinder 213 controls the lifting platform 212 to descend. After the descent, the net bed 500 disengages from the lifting platform 212, and the conveying mechanism 200 can control the horizontal movement of the net bed 500.

[0031] Preferably, a detection hole 2321 is formed at one end of the butting block 232 close to the net bed 500, and a fourth pressure sensor 234 is arranged in the detection hole 2321. When the butting block 232 butts against the net bed 500, the fourth pressure sensor 234 can butt against the net bed 500 and then send out a signal. The meaning of this signal can be that the clamping component 230 has grasped the net bed 500. When one or more of the fourth pressure sensors 234 are not butted, it proves that the clamping component 230 has not grasped the net bed 500, and the equipment needs to be repaired.

[0032] See Figures 4 - 8; The positioning mechanism 300 includes a lifting assembly 310, a positioning assembly 320, and a supporting assembly 330. Among them, the lifting assembly 310 is fixedly installed on the vertical sides of the seedbed frame 100. The lifting assembly 310 includes a moving end and a fixed end. The fixed end is fixedly installed with the seedbed frame 100, and the moving end is installed on the fixed end and can move in the vertical direction. Multiple groups of the lifting assembly 310 are arranged at intervals in the horizontal direction; the positioning assembly 320 is installed at the lifting end of each group of the lifting assembly 310. When the conveying mechanism 200 controls the net bed 500 to move directly above the positioning mechanism 300, and the lifting assembly 310 controls the lifting end to move to the set position, the positioning assembly 320 and the net bed 500 will be in a horizontal position, and the positioning assembly 320 clamps and fixes the two mutually parallel sides of the net bed 500. The supporting assembly 330 is installed at the fixed end of the lifting assembly 310. Multiple groups of the supporting assembly 330 are arranged at intervals in the vertical direction, and the multiple groups of the supporting assembly 330 are located on both sides of the lifting end and extend from both sides of the lifting end to support the net bed. When the lifting assembly 310 controls the net bed 500 to move downward to be horizontal with the supporting assembly 330, the supporting assembly 330 supports and fixes the net bed 500; specifically, during operation, the lifting assembly 310 controls the first net bed 500 to move to the lowermost end, and the lowermost group of the supporting assembly 330 fixes the net bed 500, and then sequentially upward until each group of the supporting assembly 330 is fixed with a net bed 500. When the net bed 500 needs to be taken out, it can be taken out sequentially from top to bottom.

[0033] Specifically, the fixed end of the lifting assembly 310 includes a lifting frame 311, a guide post 312, a lifting lead screw 313, and a lifting motor 314. Among them, the lifting frame 311 is set to be rectangular, and the lifting frames 311 are symmetrically arranged on the vertical sides of the seedbed frame 100 respectively; that is, each positioning mechanism 300 includes two lifting frames 311, and these two lifting frames 311 are symmetrically arranged. The guide post 312 is vertically installed inside each lifting frame 311, and two are installed at intervals inside each lifting frame 311; the lifting lead screw 313 is vertically arranged, and both ends of the lifting lead screw 313 are rotatably installed at the upper and lower ends of each lifting frame 311. That is, two lifting lead screws 313 are arranged inside each positioning mechanism 300. Specifically, the lifting lead screw 313 includes a first lifting lead screw 313 and a second lifting lead screw 313. The first lifting lead screw 313 and the second lifting lead screw 313 are respectively installed inside the two lifting frames 311, and the lifting motor 314 drives the first lifting lead screw 313 and the second lifting lead screw 313 to rotate synchronously; specifically, the lifting motor 314 can drive the first lifting lead screw 313 and the second lifting lead screw 313 to rotate synchronously by means of a belt or a chain or a gear. Furthermore, during the process of fixing the net bed 500, it can be ensured that both ends of the net bed 500 move synchronously in the vertical direction.

[0034] The lifting end of the lifting assembly 310 includes a lifting plate 315 and a guide sleeve 316. There are two groups of guide sleeves 316 arranged at intervals. The guide sleeve 316 is fixed to the lifting plate 315, and the guide sleeve 316 is slidably sleeved on the guide post 312. A lifting block 317 is fixedly installed in the middle of the lifting plate 315, and the lifting block 317 is threadedly connected to the lifting screw rod 313. Thus, when the lifting screw rod 313 rotates, the lifting plate 315 can be driven to move in the vertical direction. The support assembly 330 is installed on the lifting frame 311, and the positioning assembly 320 is installed on the lifting plate 315.

[0035] Multiple groups of positioning assemblies 320 are arranged at intervals on each lifting plate 315. Each group of positioning assemblies 320 includes a mounting plate 321, a support sleeve 322, a first telescopic device 323, and a positioning post 324. Among them, the mounting plate 321 is fixedly connected to the lifting end of the lifting assembly 310, that is, fixedly connected to the lifting plate 315.

[0036] One end of the support sleeve 322 is fixedly connected to the mounting plate 321, and the other end of the support sleeve 322 forms an opening. A support ring 3221 is fixedly installed on the inner wall of the support sleeve 322 near the opening. The first telescopic device 323 is fixed inside the support sleeve 322, and the first telescopic device 323 is located on the side of the support ring 3221 close to the mounting plate 321. The positioning post 324 passes through the support ring 3221. One end of the positioning post 324 located inside the support sleeve 322 is fixedly connected to the telescopic end of the first telescopic device 323. The end of the positioning post 324 away from the first telescopic device 323 can extend out of the opening. When the positioning post 324 extends out of the opening, the positioning post 324 can abut against the mesh bed 500. Among them, the first telescopic device 323 can be an electric push rod. During operation, through the cooperation of multiple positioning assemblies 320, the fixing and clamping of the mesh bed 500 are realized.

[0037] An installation hole 3241 is formed at one end of the positioning post 324 that abuts against the mesh bed 500. A first pressure sensor 325 is arranged in the installation hole 3241. When the positioning post 324 abuts against the mesh bed 500, the first pressure sensor 325 abuts against the mesh bed 500. At this time, the first pressure sensor 325 can send out a signal, and this signal can be considered that the positioning assembly 320 has clamped the mesh bed 500. By setting the first pressure sensor 325, it can be judged whether the clamping of the mesh bed 500 is accurate. And the clamping assembly 230 judges whether to release the mesh bed 500 based on the information of the first pressure sensor 325. After the clamping assembly 230 releases the mesh bed 500, the lifting assembly 310 can control the mesh bed 500 to move in the vertical direction.

[0038] Multiple sets of support components 330 are arranged at intervals along the vertical direction of the fixed end of the lifting component 310, that is, the lifting frame 311. Four sets of support components 330 are symmetrically arranged at the same horizontal height, and the net bed 500 is supported by the cooperation of the four sets of support components 330. The support components 330 are located on both sides of the lifting end and extend from both sides of the lifting end to support the net bed.

[0039] Each set of support components 330 includes a support arm 331, a support column 332, a support plate 333, a rotary cylinder 334, and an abutting plate 335. Among them, two support arms 331 are provided. The two support arms 331 are spaced apart and horizontally fixed to the fixed end of the lifting component 310. The two ends of the support column 332 are respectively rotatably connected to the two support arms 331. One side of the support plate 333 in the length direction is fixedly connected to the support column 332, and the other side is used to abut against the support net bed 500. The two ends of the abutting plate 335 are respectively fixedly connected to the support arms 331. The abutting plate 335 is located on the side of the support column 332 away from the lifting component 310. When the support plate 333 rotates to the horizontal position, the support plate 333 and the abutting plate 335 are parallel and abut against each other. When the support plate 333 rotates to the horizontal position, it is abutted and supported by the abutting plate 335, and the upper side of the support plate 333 supports the net bed 500. The width of the support plate 333 is greater than the width of the abutting plate. When the support plate 333 rotates to the vertical direction, when the net box moves in the vertical direction, it will not interfere with the abutting plate. On the support plate 333, the horizontal direction perpendicular to the support column 324 is defined as the width direction, and the direction parallel to the length of the support column is defined as the length direction.

[0040] When the positioning component 320 grabs the net bed 500, the corresponding support component 330 that supports the net bed 500 starts to work. The abutting plate 335 rotates to the horizontal position and waits for the net bed 500 to descend. When specifically placing, the support components 330 start to work in sequence from the bottommost one.

[0041] A second pressure sensor 336 is fixedly arranged on the side of the support plate 333 that abuts against the net bed 500. When the support plate 333 abuts against the net bed 500, the second pressure sensor 336 abuts against the net bed 500. By setting the second pressure sensor 336, it can be judged whether it is accurate when supporting and fixing the net bed 500. And the positioning component 320 judges whether to release the net bed 500 based on the information of the first pressure sensor 325.

[0042] The spraying mechanism 400 is fixedly installed at the bottom of the seedling bed frame 100 and is located on one side of the positioning mechanism 300. The spraying mechanism 400 sprays the net bed 500 on the adjacent positioning mechanism 300.

[0043] The working process of Embodiment 1 of the present invention is as follows: During operation, the operator places the planted mesh bed 500 into the positioning shallow groove 2121 on the lifting platform 212. The drive motor 223 controls the carriage 221 to move to the initial position, i.e., directly above the lifting platform 212. Then, the lifting cylinder 213 controls the lifting platform 212 to rise, and the clamping assembly 230 grabs the mesh bed 500. After that, the drive motor 223 controls the horizontal movement of the carriage 221 until it is directly above the position to be placed, i.e., directly above a certain set of positioning mechanisms 300. At this time, the positioning mechanism 300 controls the lifting assembly 310 to rise until the positioning assembly 320 is level with the mesh bed 500, and the positioning assembly 320 grabs the mesh bed 500. After the positioning assembly 320 grabs the mesh bed 500, based on the detection value of the first pressure sensor 325, after determining that the grabbing is successful, the clamping assembly 230 releases the mesh bed 500. At this time, the lifting assembly 310 controls the mesh bed 500 to move in the vertical direction. At the same time, the support assembly 330 waiting to receive the mesh bed 500 controls the support plate 333 to unfold. Finally, driven by the lifting assembly 310, the mesh bed 500 abuts against the support plate 333. At the same time, the second pressure sensors 336 all indicate successful support, and the placement of the mesh bed 500 can be completed.

[0044] Second Embodiment See Figure 9 , the difference between this embodiment and the first embodiment lies in the mesh bed 500. In order to improve the accuracy of the movement process of the mesh bed 500 and the accuracy of the information transmission of the first pressure sensor 325, the second pressure sensor 336, and the third pressure sensor 319, the mesh bed 500 is improved.

[0045] Specifically, the net bed 500 includes a frame 510 and a net plate 520; the net plate 520 is fixed to the inner side of the frame 510. The frame 510 is rectangular, and a plurality of first clamping holes 511 are respectively opened on two relatively parallel sides of the frame 510, and the first clamping holes 511 are blind holes. The first clamping holes 511 cooperate with the conveying mechanism 200. Specifically, when the conveying mechanism 200 clamps the net bed 500, the abutment block 232 will enter the first clamping hole 511 and abut against the bottom of the first clamping hole 511. A plurality of second clamping holes 512 are respectively opened on two sides of the frame 510 away from the first clamping hole 511, and the second clamping holes 512 are blind holes. The second clamping holes 512 cooperate with the positioning assembly 320. Specifically, when the positioning assembly 320 clamps the net bed 500, the positioning column 324 enters the second clamping hole 512 and abuts against the bottom of the second clamping hole 512. The frame 510 is provided with limiting grooves 513 on both sides of the second clamping hole 512, wherein the limiting grooves 513 are located near the two ends, and the second supporting hole is located in the middle. During installation, the two do not conflict. When the support plate 333 is rotated to horizontal, the support plate 333 can be embedded in the limiting groove 513. Through the above design, during operation, the accuracy of the movement of the net bed 500 and the accuracy of the information transmitted by the first pressure sensor 325, the second pressure sensor 336, and the third pressure sensor 319 are greatly improved.

[0046] Third embodiment See also Figure 10 The difference between this embodiment and the first embodiment lies in the spray mechanism 400. In order to improve the uniformity and stability of spraying, the spray mechanism 400 is improved.

There are four wheels 414 arranged in an array, including two front wheels and two rear wheels; the four wheels 414 are respectively embedded in the slideways 412 on both vertical sides. A working motor 415 is arranged in the mobile trolley 410, and the working motor 415 drives the two front wheels or the two rear wheels to rotate. Optionally, a drive shaft is rotatably arranged in the mobile trolley 410, and the two ends of the drive shaft are respectively connected to the two front wheels or the two rear wheels through belts or chains; the working motor 415 and the drive shaft are connected through chains or gears.

[0049] The rotating assembly 420 is fixedly arranged on the mobile trolley 410, and the rotating assembly 420 drives the mounting arm to rotate forward or backward by 90 degrees; the spray rod 430 is fixed on the mounting arm 440, and a plurality of spray rods 430 are arranged at intervals along the vertical direction. When the mounting arm 440 rotates, each spray rod 430 can cover a net bed 500. The lower side of the spray rod 430 is fixed with a spray head 431, and a plurality of spray heads 431 are arranged at equal intervals along the length direction.

At this time, all the spray rods 430 will rotate to directly above all the net beds 500. During the spraying process, by moving the mobile trolley 410 in the width direction, uniform spraying of the net beds 500 can be achieved.
