TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural seedling raising equipment, in particular to a multifunctional automatic production line suitable for paper pot seedling raising. BACKGROUND

[0002] In the field of modern agricultural engineering, the seedling raising link plays a key role in the high quality and high yield of crops. Traditional seedling raising is mainly operated by hand, which has significant defects such as labor-intensive, low efficiency, and difficulty in ensuring operation precision and consistency, and cannot meet the needs of modern agricultural scale and precision production. With the advancement of agricultural mechanization, although some seedling raising equipment has emerged, there are still many technical bottlenecks for the specific process of paper pot seedling raising. For example, there is currently a lack of a comprehensive production line with high integration, easy operation, and the ability to effectively improve the efficiency and quality of paper pot seedling raising. Moreover, there is a serious lack of automated operation in the key paper pot unfolding link, which relies heavily on manual operation. At the same time, traditional mechanical seeding has poor precision, low alignment accuracy, and damage to seeds, and air suction seeding has the disadvantage of easy clogging, which seriously affects the continuity and precision of seeding and thus reduces the quality of seedling raising.

[0068] (2) Integrated device for cultivating trays, pots, and soil layering

[0069] like Figure 2 As shown, the integrated device 1 for spreading and spreading soil in the seedling trays is a key component of the seedling production line. It mainly completes the integrated operation of spreading paper pots, placing trays, and spreading substrate to create seedling trays.

[0070] The cultivation tray spreading and soil-laying integration device 1 is connected to the conveying device 7, and the frame height is consistent after connection. The tray lifting mechanism 1.2 is installed below the integration device frame 1.1, pushing the empty trays 8.1 placed on the tray plate 1.2.6 upward one by one. The top block assembly 1.3 is installed on both sides of the integration device frame 1.1. The top block in the top block assembly 1.3 is horizontally attached to the top block fixing plate, and the top block can rotate upward around the pin axis. The tray pushing cylinder module 1.4 is installed at the rear end of the integration device frame 1.1, and the cylinder pushing plate can be pushed forward. The spreading mechanism 1.5 is fixed above the integration device frame 1.1, and the soil-laying mechanism 1.6 is installed at the top of the integration device frame 1.1. The soil box 1.6.1 of the soil-laying device passes through the base plate 1.5.7 of the spreading mechanism, and the base plate 1.5.7 can move up and down. The conveying wheel 1.8 and the roller brush 1.7 are installed at the front end of the integration device frame 1.1 through the diamond bearing seat 1.9, providing forward power for the cultivation tray 8 and smoothing out excess substrate.

[0071] like Figure 3As shown, the lifting disc mechanism 1.2 includes: servo motor I 1.2.1, servo motor I fixed plate 1.2.2, lifting disc guide rod 1.2.3, linear bearing mounting plate 1.2.4, lifting disc linear bearing 1.2.5, supporting plate 1.2.6, buffer block 1.2.7, lifting disc screw rod 1.2.8, lifting disc screw rod nut 1.2.9, synchronous pulley mounting shaft sleeve 1.2.10, large synchronous pulley 1.2.11, synchronous belt 1.2.12, small synchronous pulley 1.2.13 and other components. The lifting disc mechanism 1.2 is installed below the integrated device rack 1.1 as a whole through the servo motor fixed plate 1.2.2 and the linear bearing mounting plate 1.2.4. The lifting disc mechanism 1.2 drives the small synchronous pulley 1.2.13 to move by the servo motor I 1.2.1, at the same time drives the lifting disc screw rod nut 1.2.9 connected with the large synchronous pulley 1.2.11 to rotate, drives the lifting disc screw rod 1.2.8 and the supporting plate 1.2.6 connected with the top end of the lifting disc screw rod 1.2.8 to make lifting action, when the supporting plate rises to the top end, the last tray 8.1 on the supporting plate completes the disc feeding, the supporting plate will return to the lowest point under the action of the servo motor, and the full tray continues the next disc lifting operation, and the lifting disc guide rod 1.2.3 can keep the stability of the supporting plate 1.2.6 carrying the tray.

[0072] As shown, Figure 4 The exhibition tray mechanism 1.5 includes: stepper motor 1.5.1, exhibition tray linear bearing 1.5.2, buffer sleeve 1.5.3, screw nut 1.5.4, coupling 1.5.5, stepper motor fixed plate 1.5.6, exhibition tray base plate 1.5.7, transverse guide rod fixed plate 1.5.8, exhibition tray piece 1.5.9, transverse guide rod 1.5.10, transverse screw rod 1.5.11, transverse sliding block 1.5.12, longitudinal guide rail fixed plate 1.5.13, longitudinal sliding block 1.5.14, longitudinal guide rod 1.5.15, longitudinal screw rod 1.5.16, screw rod bearing 1.5.17 and other components. The exhibition tray mechanism 1.5 is fixed as a whole through the four longitudinal guide rail fixed plates 1.5.13 and the integrated device rack 1.1, at the same time the stepper motor fixed plate 1.5.6 is also installed on the integrated device rack 1.1 to prevent the motor from rotating. The exhibition tray mechanism 1.5 drives the screw rod to rotate and converts the rotary motion of the screw rod into the linear motion of the sliding block through the three stepper motors 1.5.1, so that the exhibition tray base plate 1.5.7 installed on the longitudinal sliding block 1.5.14 can move up and down, and the exhibition tray piece 1.5.9 installed on the transverse sliding block 1.5.12 can move left and right, and the exhibition tray piece 1.5.9 can complete the exhibition tray operation.

[0073] As shown, Figure 5As shown, the soil-laying mechanism 1.6 includes: a soil box 1.6.1, a bearing 1.6.2, a feeding roller 1.6.3, a chain I 1.6.4, a small sprocket 1.6.5, a servo motor II mounting plate 1.6.6, a servo motor II 1.6.7, a gear dust cover 1.6.8, a gear 1.6.9, and a circular bearing seat 1.6.10. The soil-laying mechanism 1.6 is fixed to the top of the integrated device frame 1.1 with screws on both sides, and the lower end of the soil box 1.6.1 passes through the base plate 1.5.7 of the spreading mechanism 1.5. The soil-laying mechanism 1.6 drives the feeding roller 1.6.3 on one side via a chain drive through the servo motor II 1.6.7. The gear 1.6.9 on the other side of the soil box 1.6.1 meshes with each other, and the four feeding rollers 1.6.3 rotate simultaneously. The substrate in the soil box 1.6.1 is transported through the grooves of the feeding rollers 1.6.3 to the lower outlet of the soil box, thus completing the soil-laying operation.

[0074] The working principle of the cultivation tray spreading and soil-laying integration device is as follows: Before operation, the two spreading pieces of the spreading mechanism (installed on the horizontal guide rod fixing plate and the horizontal slider respectively) are manually inserted into the two sides of the paper pot. The device is then started. The spreading piece installed on the horizontal guide rod fixing plate remains stationary, while the spreading piece installed on the horizontal slider unfolds under the action of the slider, thus unfolding the paper pot. Subsequently, the servo motor I of the lifting mechanism rotates at a certain angle, driving the pallet to rise one tray distance. As the pallet rises, it pushes open the top block assembly (4 top blocks) and lands on the reset top blocks. Then, the servo motor II of the soil-laying device rotates at a certain angle. Four feeding rollers are driven to fill the cultivation trays with substrate, preventing the paper pots from shrinking back. Then, the base plate of the spreading mechanism is driven upward by the longitudinal slider to pull the spreading pieces out from both sides of the paper pot, thus completing the integrated operation of spreading and integrating the cultivation trays. Finally, the pushing cylinder module pushes the integrated cultivation trays onto the conveyor rollers. The cultivation trays move towards the conveying device under the drive of the conveyor rollers. When passing through the roller brush, excess substrate is brushed off and leveled. At the same time, the pushing cylinder module performs a reset action, and the stepper motor of the spreading mechanism controls the base plate to move downward and the right spreading piece to retract, preparing for the next integration and production of cultivation trays.

[0075] (3) Acupressure device

[0076] like Figure 6 As shown, the main function of the pressing device 2 is to press out the sowing holes and compact the substrate. The device includes: pressing device mounting frame 2.1, pressing head 2.2, pressing plate 2.3, connecting plate 2.4, pressing cylinder module 2.5 and other components.

[0077] The whole press hole device 2 is fixed on the leftmost side above the rack 7.1 of the conveying device 7 through the two side mounting frames 2.1, and the two press hole cylinder modules 2.5 are fixed inside the two side mounting frames 2.1. The press hole cylinder modules 2.5 are connected with the pressing plate 2.3 through the connecting plate 2.4, the press hole heads 2.2 are installed on the pressing plate 2.3 according to the size of the unfolded paper pot, and the press hole heads 2.2 ensure that each press hole head is pressed into the center of the corresponding pot body.

[0078] The working principle of the press hole device is as follows: the cultivation tray is moved to the press hole device under the driving of the conveying device, and the micro switch at the position is triggered when the cultivation tray passes the right side of the press hole device. The conveying device stops working and delays for a period of time. During the period of time, the cultivation tray is accurately stopped right below the press hole device. The press hole cylinder modules drive the pressing plate to move downward. The press hole heads press small pits on the cultivation tray full of substrate, which is convenient for seeding and plays a role in compacting the loose substrate. Then the press hole cylinder modules reset, and the conveying device continues to work to advance the cultivation tray to the next seedling cultivation process.

[0079] (4) Precise alignment and precision seeding device

[0080] As shown in Figure 7 , the precise alignment and precision seeding device 3 is the core component of the paper pot seedling production line, and the main functions are precise alignment of the seed guide pipe, precision control of the seed quantity of the filling hole, and driving of the seeding mechanism to complete the seeding operation. The device comprises: a seeding device mounting frame 3.1, a seeding drive mechanism 3.2, a vertical pipe 3.3, a seed guide pipe bottom disc 3.4, a seed guide pipe 3.5, a seed guide pipe support rod 3.6, a seed guide pipe upper disc 3.7, a seeding disc 3.8, a seed box 3.9, and the like.

[0081] The whole precise alignment and precision seeding device 3 is fixed on the leftmost side above the rack 7.1 of the conveying device 7 through the two side mounting frames 3.1, and the rear of the press hole device 2. The seeding drive mechanism 3.2 and the vertical pipe 3.3 are installed on the conveying rack 7.1, the seed guide pipe bottom disc 3.4 is installed above the two side mounting frames 3.1, the seed guide pipe upper disc 3.7 is connected with the seed guide pipe bottom disc 3.4 through the seed guide pipe support rod 3.6, the seed guide pipe 3.5 passes through the upper disc 3.7 and the bottom disc 3.4 in sequence and is in interference fit, the seed box 3.9 is installed above the seed guide pipe upper disc 3.7, the filling hole positions inside the seed box 3.9 are recessed, which is beneficial to filling, the seeding disc 3.8 is clamped between the two, and can move along the mounting strips on the two sides of the seed box 3.9. The seeding disc 3.8 selects different specifications of the filling hole size according to the actual seeding requirement, so as to realize precision control of the seed quantity.

[0082] The fixing part 3.2.1 of the sowing drive mechanism 3.2 is installed on the frame. The component mounting plate 3.2.3 is installed above the fixing part 3.2.1 and is used to install the touch switch 3.2.2, the limit block 3.2.8 and the crank block 3.2.5. The driving wheel 3.2.4 is installed on the crank block. The return spring 3.2.9 connects the crank block and the component mounting plate. The connecting rod 3.2.10 connects the crank block and the small slider 3.2.6. The small slider can slide along the slide rail 3.2.7. The slide rail and the swing arm fixing plate 3.2.12 are installed on the vertical tube 3.3. The swing arm 3.2.11 is connected to the swing arm fixing plate in the middle and the small slider and the sowing tray 3.8 are connected at both ends respectively.

[0083] Working principle of the sowing device: The cultivation tray moves towards the sowing device under the drive of the conveyor. The front end of the cultivation tray pushes the drive wheel and drives the crank block to rotate. The crank block triggers the touch switch, the conveyor stops working and delays for a period of time. The crank block also pulls the small slider through the connecting rod to move. The small slider then moves the swing arm counterclockwise, pushing the seed-filled sowing tray to the left a distance. The seeds fall into the corresponding paper pot holes through the seed guide tube. Then the conveyor continues to work. After the seeded cultivation tray is sent away, the return spring resets the crank block and the sowing tray is also reset, completing the seed filling and preparing for the next sowing.

[0084] (5) Soil covering device

[0085] like Figure 8 As shown, the main function of the soil covering device 4 is to cover the seeded cultivation tray with substrate.

[0087] Working principle of the soil covering device: The cultivation tray moves towards the soil covering device under the drive of the conveyor. When it passes the right side of the soil covering device, it triggers the micro switch at that position. The soil covering pulley and the stirring shaft start to rotate. The conveyor continues to move the cultivation tray forward. The soil covering belt transports the substrate above it to the right end and it falls into the cultivation tray. The stirring shaft can stir the substrate, which helps the substrate fall onto the soil covering belt. When the entire cultivation tray passes the micro switch, the micro switch resets, and the soil covering pulley and the stirring shaft stop rotating, completing the soil covering operation of the cultivation tray.

[0088] (6) Spraying device

[0089] like Figure 9The main function of the spraying device 5 is to spray water and fertilizer on the covered cultivation tray, which includes the spraying device mounting frame 5.1, end cap 5.2, spray pipe 5.3, nozzle 5.4, elbow 5.5, water supply pipe 5.6, water pump 5.7 and other components.

[0090] The spraying device 5 is fixed on the frame 7.1 of the conveying device 7 above the spraying device 5.1, behind the covering device 4, the spray pipe 5.3 is fixed on one side of the mounting frame 5.1, and the two ends of the spray pipe 5.3 are connected with the end cap 5.2 and the elbow 5.5, respectively, eight nozzles 5.4 are installed below the spray pipe 5.3, the two sides of the water supply pipe 5.6 are connected with the elbow 5.5 and the water pump 5.7, and the water pump 5.7 is installed below the conveying frame 7.1.

[0091] The working principle of the spraying device is that the cultivation tray is moved to the spraying device under the action of the conveying device, triggers the micro switch at this position when passing through the spraying device, the water pump starts to work, the conveying device continues to move forward with the cultivation tray, the nozzle sprays the water and fertilizer mixture to the cultivation tray, and when the cultivation tray as a whole passes through the micro switch, the micro switch resets, the water pump stops working, and the spraying work of the cultivation tray is completed.

[0092] (7) Stacking device

[0093] As shown in Figure 10 The main function of the stacking device 6 is to stack the cultivation trays in order after the seedlings are grown, which includes the stacking device frame 6.1, top block combination 6.2, tray pushing plate 6.3, tray pushing guide rod 6.4, stacking cylinder fixing frame 6.5, stacking cylinder 6.6, stacking linear bearing 6.7, stacking cylinder mounting plate 6.8 and other components.

[0094] The stacking device 6 is fixed on the frame 7.1 of the conveying device 7 above the rightmost side of the stacking device 6.1, behind the spraying device 5, four top block combinations 6.2 are installed on the front and rear sides of the frame 6.1, the tray pushing plate 6.3 is connected with the tray pushing guide rod 6.4 and the stacking cylinder 6.6, the stacking cylinder 6.6 is fixed below the stacking cylinder mounting plate 6.8, four stacking linear bearings 6.7 are installed on the four corners of the stacking cylinder mounting plate 6.8, the tray pushing guide rod 6.4 passes through the stacking linear bearing 6.7 and can move up and down, the tray pushing mechanism is installed on the stacking cylinder fixing frame 6.5, and the stacking cylinder fixing frame 6.5 is installed below the conveying frame 7.1.

[0095] Working principle of the stacking tray device: The seedling trays, once completed, move towards the stacking tray device under the drive of the conveyor. When they reach the rightmost end of the stacking tray device, a micro switch at that position is triggered. The conveyor stops working and delays for a period of time. During this time, the seedling tray stops precisely in the middle of the stacking tray device. The stacking tray cylinder drives the pusher plate to push the seedling tray upwards. As the seedling tray rises, it pushes open the top block and falls onto the reset top block. Then the stacking tray cylinder resets, and the conveyor continues to work, carrying the next seedling tray towards the stacking tray device. The above stacking operation is repeated to complete the orderly stacking of the seedling trays.

[0096] (8) Conveying device

[0097] like Figure 11 As shown, the main function of the conveying device 7 is to convey the cultivation tray and provide operating signals for each device by triggering the micro switch. The device includes: conveyor frame 7.1, baffle 7.2, conveyor belt 7.3, conveyor pulley 7.4, vertical bearing seat 7.5, conveyor pulley shaft 7.6, micro switch 7.7, DC motor 7.8, chain II 7.9, large sprocket 7.10 and other components.

Baffles 7.2 are installed on the upper sides of the conveyor frame 7.1. Vertical bearing seats 7.5 are installed on the lower sides of the conveyor frame 7.1. The conveyor pulley shaft 7.6, which fixes the conveyor pulley 7.4, is coaxially installed with the vertical bearing seats 7.5 on both sides. The conveyor belt 7.3 is spread open by the conveyor pulley 7.4. Microswitches 7.7 are installed in the corresponding positions inside the baffles 7.2 on both sides for triggering signals. The DC motor 7.8 is fixed below the conveyor frame 7.1 and drives the sprocket 7.10 to rotate through the chain 7.9. The sprocket 7.10 is coaxially connected with the rightmost conveyor pulley shaft 7.6.

[0099] Working principle of the conveying device: During operation, the DC motor drives the rightmost conveyor belt pulley to rotate, and the two conveyor belts move clockwise from left to right. When the potting and soil-laying integration device pushes the cultivation tray to the leftmost side of the conveying device, the conveying device drives the cultivation tray to move from left to right, passing through the microswitches installed at the corresponding positions of the pressing, covering, spraying and stacking devices in sequence. Each device works together to execute the corresponding operation instructions, and finally completes the conveying task of the paper pot seedling production line.
