[0002] In the field of modern agricultural engineering, the seedling raising process plays a key role in laying the foundation for the high quality and high yield of crops. Traditional seedling raising is mainly manual operation, which has significant defects such as labor-intensive, low efficiency, and difficulty in ensuring operation accuracy and consistency. It cannot meet the needs of large-scale and precise production in modern agriculture. 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, convenient operation, and the ability to effectively improve the efficiency and quality of paper pot seedling raising; and there is a serious lack of automated operation in the key paper pot expansion link, which relies more on manual labor; at the same time, the traditional mechanical sowing has poor accuracy, low positioning accuracy, and damage to seeds.

After going through various operating procedures in sequence, the seedling raising operation of the paper pot is completed.

[0067] The working principle of the production line: When working, the internal mechanical structure of the cultivation tray potting soil-laying integrated device operates in sequence to complete the integrated operation of unfolding paper pots, placing trays and laying bottom soil. The plate-pushing cylinder module pushes the prepared cultivation tray to the conveying device, and the roller brush flattens the excess matrix.

The baffles on both sides of the conveying device are equipped with micro switches at the corresponding positions of the hole-pressing, soil-covering, spraying and stacking devices. The micro switches are triggered when the cultivation tray passes by, and each device of the seedling production line automatically performs the corresponding operation. The cultivation tray completes the seedling process in sequence under the operation of each device, realizing the automated operation of paper pot seedling cultivation.

The exhibition bowl mechanism 1.5 is fixed to the integrated device frame 1.1 through four longitudinal guide rail fixing plates 1.5.13, and the stepper motor fixing plate 1.5.6 is also installed on the integrated device frame 1.1 to prevent the motor from rotating. The exhibition bowl mechanism 1.5 is driven by three stepper motors 1.5.1, which convert the rotational motion of the screw rod into the linear motion of the slider, so that the exhibition bowl base plate 1.5.7 installed on the longitudinal slider 1.5.14 can move up and down, and the exhibition bowl piece 1.5.9 installed on the transverse slider 1.5.12 can move left and right to complete the exhibition bowl operation.

[0074] The working principle of the integrated device for spreading pots and spreading soil on the cultivation tray: before work, the two spreading pot pieces of the spreading pot mechanism (respectively installed on the transverse guide rod fixing plate and the transverse slider) are manually inserted into the two sides of the paper pot, and the device is started. The spreading pot piece installed on the transverse guide rod fixing plate is fixed, and the spreading pot piece installed on the transverse slider is spread out under the drive of the transverse slider to spread out the paper pot; then the servo motor I of the tray lifting mechanism rotates a certain angle to drive the support plate to rise the distance of a tray. When the tray rises, it pushes open the top block combination (4 top blocks) and then falls on the reset top block; then the servo motor II of the soil spreading device rotates a certain angle, Drive four unloading rollers to cover the culture tray with the unfolded paper pot with the matrix to prevent the paper pot from shrinking; then the base plate of the spreading pot mechanism is driven upward by the longitudinal slider to pull the spreading pot pieces out from both sides of the paper pot, thus completing the integrated operation of the culture tray, spreading pot and soil integration; finally, the pushing plate cylinder module pushes the integrated culture tray onto the conveying wheel, and the culture tray moves toward the conveying device driven by the conveying wheel. When passing through the roller brush, the excess matrix will be brushed off and scraped flat. At the same time, the pushing plate cylinder module performs a reset action, and the stepper motor of the spreading pot mechanism controls the base plate to move downward and the spreading pot piece on the right to retract, preparing for the next integration of the culture tray.

[0075] (3) Acupuncture device

The cavitation pressing cylinder modules 2.5 are connected to the pressing plate 2.3 through the connecting plate 2.4. The cavitation pressing heads 2.2 are installed on the pressing plate 2.3 according to the size of the unfolded paper pot to ensure that each cavitation pressing head is pressed into the corresponding center of the pot body.

[0078] The working principle of the hole pressing device: the cultivation tray moves toward the hole pressing device driven by the conveying device, and triggers the micro switch at that position when passing the right side of the hole pressing device. The conveying device stops working and delays for a period of time. During this period of time, the cultivation tray stops precisely under the hole pressing device, and the hole pressing cylinder module pushes the pressure plate to move downward. The hole pressing head presses small pits on the cultivation tray covered with substrate for easy sowing and compacts the loose substrate. Then the hole pressing cylinder module resets, and the conveying device continues to work, carrying the cultivation tray to the next seedling raising process.

[0079] (4) Precision seeding device

[0080] like Figure 7 As shown, the precise alignment and precision sowing device 3 is the core component of the paper pot seedling production line, and its main functions are to precisely align the seed guide tube, precisely control the number of seeds in the seed hole, and drive the sowing mechanism to complete the sowing operation.

[0081] The precise positioning and precision seeding device 3 is fixed as a whole on the frame 7.1 of the conveying device 7 through the mounting frames 3.1 on both sides, and the seeding drive mechanism 3.2 and the vertical pipe 3.3 are installed on the conveying frame 7.1 behind the hole pressing device 2. The seeding tube chassis 3.4 is installed on the mounting frames 3.1 on both sides, and the seed guide tube upper plate 3.7 is connected to the seed guide tube chassis 3.4 through the seed guide tube support rod 3.6. The seed guide tube 3.5 passes through the upper plate 3.7 and the chassis 3.4 in sequence and is an interference fit. The seed box 3.9 is installed above the seed guide tube upper plate 3.7. The positions of the seed filling holes inside the seed box 3.9 are all recessed, which is conducive to seed filling. The seeding plate 3.8 is stuck between the two and can move along the mounting strips on both sides of the seed box 3.9. The seeding plate 3.8 selects specifications of different seed filling hole sizes according to actual sowing needs, thereby realizing precise control of the number of seeds.

[0082] The fixing part 3.2.1 of the sowing driving mechanism 3.2 is installed on the frame, and 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.

[0083] The working principle of the sowing device: the cultivation tray moves toward the sowing device driven by the conveying device, and the front end of the cultivation tray pushes the moving wheel and drives the crank block to rotate at the same time. The crank block triggers the touch switch, the conveying device stops working and delays for a period of time, and the crank block also pulls the small slider to move through the connecting rod, and the small slider drives the rocker bar to rotate counterclockwise, pushing the seeding tray filled with seeds to the left for a distance, and the seeds fall into the corresponding paper pot holes through the seed guide tube. Then the conveying device continues to work, and after the sown cultivation tray is sent away, the reset spring resets the crank block, and the sowing tray is also reset accordingly, completing the seed filling and preparing for the next sowing.
