[0029] See also Figure 2 As shown, the inflation assembly includes a cylinder body 10, a piston rod 101, a return spring 102 and a three-way pipe 103. Six cylinder bodies 10 are evenly spaced and fixedly connected to the upper part of the side where the left and right movable frames 5 are close to each other. The inner sides of the six cylinder bodies 10 are slidably connected with piston rods 101. The ends of the left and right piston rods 101 that are close to each other are respectively connected to the outer sides of the left and right cylinder bodies 10 with return springs 102. The tops of the left and right cylinder bodies 10 that are far away from each other are connected to three-way pipes 103. The two tail ends of the three-way pipes 103 are respectively connected to the bottom of each group of two clamping airbags 9. The three-way pipes 103 can realize the inflation of the clamping airbags 9.

[0030] See also Figure 4As shown, the clamping assembly includes a rotating shaft 11, an L-shaped pressure block 111 and a driving assembly. The top of the electric lifting frame 3 is symmetrically connected to the rotating shaft 11, and the middle parts of the front and rear rotating shafts 11 are fixedly covered with L-shaped pressure blocks 111. When the L-shaped pressure blocks 111 rotate and contact the seedling basin, the L-shaped pressure blocks 111 can press and fix the seedling basin. A driving assembly is arranged between the rotating shaft 11 and the electric lifting frame 3. When the driving assembly is operating, the driving assembly can drive the rotating shaft 11 to rotate; the driving assembly includes a worm gear 112, a driving motor 113 and a worm 114. The right sides of the rotating shafts 11 on the front and rear sides are fixedly covered with worm gears 112, and the right sides of the front and rear outer sides of the electric lifting frame 3 are installed with driving motors 113. The output shaft ends of the front and rear driving motors 113 are fixedly connected with worm gears 114, and the worm gear 114 is engaged with the worm gear 112.

[0031] First, pour an appropriate amount of water into the placement frame 4, and then place the seedling pot planted with broccoli seedlings in the placement frame 4, the seedling pot is limited in contact with the electric lifting frame 3, and the bottom of the seedling pot is in contact with the water in the placement frame 4, and the driving motor 113 is started to drive the worm 114 to rotate, and the worm 114 drives the worm gear 112 to rotate, and the rotation of the worm gear 112 drives the rotating shaft 11 to rotate, and the rotation of the rotating shaft 11 drives the front and rear L-shaped pressing blocks 111 to swing downward, and the front and rear L-shaped pressing blocks 111 swing downward and contact the top edge of the seedling pot, and the front and rear L-shaped pressing blocks 111 press the seedling pot tightly on the electric lifting frame 3, and then the broccoli seedlings can be cultivated, and the water in the placement frame 4 penetrates into the soil of the seedling pot, which also plays a role in adhesively bonding the broccoli seedlings in the seedling pot. When the electric lifting frame 3 moves upward to the maximum stroke, the electric lifting frame 3 is closed, the L-shaped pressing block 111 and the seedling basin stop moving upward, and the rod-shaped position of the broccoli seedlings in the seedling basin corresponds to the clamping airbags 9 on the left and right sides, and the electric bidirectional screw 51 is started to rotate forward. The screw 51 rotates forward to drive the left and right movable frames 5 to move toward each other, and the movable frame 5 drives the left and right L-shaped grid plates 8 to move toward each other through the connecting spring 7, and the L-shaped grid plates 8 drive the left and right clamping air bags 9 to move toward each other, and the left and right clamping air bags 9 move to both sides of the broccoli seedlings. At the same time, the movable frame 5 also drives the left and right cylinder bodies 10 to move toward each other, and the cylinder bodies 10 drive the left and right piston rods 101 to move toward each other through the return spring 102, and the left and right piston rods 101 move to the inside of the base 1, and the piston rod 101 contacts the inside of the base 1 and is limited. When the left and right L-shaped grid plates 8 contact each other, the left and right L-shaped grid plates 8 contact the limit blocks 52 and are limited. When the lifting frame 5 is in the position, the L-shaped grid plates 8 on the left and right sides stop moving, and the movable frames 5 on the left and right sides continue to move in the direction of approaching each other to compress the connecting spring 7. The movable frame 5 continues to drive the cylinder bodies 10 on the left and right sides to move in the direction of approaching each other, and the cylinder body 10 continues to move to compress the return spring 102. Since the piston rod 101 is in contact with the base 1 and is limited, the piston rod 101 pushes the air in the moving cylinder body 10 into the three-way pipe 103, and the air in the three-way pipe 103 is discharged into the clamping airbag 9. As the air is discharged, the clamping airbag 9 expands and clamps the broccoli seedlings. The electric bidirectional screw 51 is turned off, the movable frame 5 stops moving, and then the electric lifting frame 3 is started to move downward to drive the seedling pot downward through the L-shaped pressing block 111. Since the broccoli seedlings are clamped and fixed,The seedling basin moves downward and disengages from the clamped broccoli seedlings, thus completing the separation and removal of the broccoli seedlings from the seedling basin at one time, so that the broccoli seedlings can be taken out one by one without manual operation, which is more convenient and improves the overall work efficiency. When the electric lifting frame 3 moves downward and resets, the electric lifting frame 3 is closed, and then the electric bidirectional screw 51 is started to reverse and drive the left and right movable frames 5 to move away from each other. The movable frame 5 first stretches and resets the connecting spring 7, and at the same time, the movable frame 5 also drives the left and right cylinder bodies 10 to move away from each other. The reset spring 102 is stretched and reset first, and the piston rod 101 draws the air in the clamping airbag 9 back into the cylinder body 10 through the three-way pipe 103. As the air is pumped away, the clamping airbag 9 continuously contracts and resets to loosen the broccoli seedlings, and the broccoli seedlings fall downward, and the operator can then The collecting container moves to the bottom of all the broccoli seedlings, and the collecting container collects all the cultivated broccoli seedlings. As the left and right movable frames 5 continue to move away from each other and reset, the movable frame 5 drives the left and right L-shaped grid plates 8 to move and reset through the connecting spring 7. The L-shaped grid plates 8 reset and disengage from the limit blocks 52. The L-shaped grid plates 8 drive the left and right clamping air bags 9 to move and reset in the direction away from each other. At the same time, the movable frame 5 also drives the left and right cylinders 10 to move and reset, so that the cultivated broccoli seedlings can be subsequently processed. The driving motor 113 is then started to drive the worm 114 to rotate in the opposite direction. The worm 114 drives the worm gear 112 to rotate in the opposite direction. The worm gear 112 drives the L-shaped pressing block 111 to swing upward and reset through the rotating shaft 11. The L-shaped pressing block 111 releases the seedling pot, and the operator can take the seedling pot out of the placement frame 4.

[0032] See also Figure 5-Figure 7As shown, the broccoli seedling raising device also includes a sunshade assembly installed on the base 1, and the sunshade assembly includes a fixed plate 12, a winding roller 121, a sunshade cloth 122, a spiral spring 1221 and a pulling assembly. The middle parts of the left and right side surfaces of the base 1 are fixedly connected with a fixed plate 12, and the positions of the left and right fixed plates 12 away from each other are rotatably connected with the winding roller 121, and the front and rear winding rollers 121 are both wound with sunshade cloth 122. When the sunshade cloth 122 is pulled out, the sunshade cloth 122 can block the sun to prevent the sunlight from exposing the broccoli seedlings. A spiral spring 1221 is connected between the winding roller 121 and the fixed plate 12, and a pulling assembly is provided on the base 1. When the pulling assembly is in operation, the pulling assembly can drive the sunshade cloth 122 to move; the pulling assembly includes a temperature sensor 123, a rotating plate 124, and a driving rod 125, a rotating rod 126 and a stepper motor 127. The stepper motors 127 are symmetrically installed on the left and right sides of the middle part of the base 1. The output shaft ends of the left and right stepper motors 127 are fixedly connected to the rotating rods 126. The ends of the left and right rotating rods 126 rotate and pass through the base 1. The ends of the left and right rotating rods 126 away from each other are fixedly connected to the rotating plates 124. The length of the right rotating plate 124 is longer than that of the left rotating plate 124. The tail ends of the left and right rotating plates 124 are fixedly connected to the driving rods 125. The front and rear driving rods 125 are respectively fixedly connected to the head ends of the front and rear sunshade cloths 122. When the driving rods 125 rotate, the driving rods 125 can drive the head end of the sunshade cloth 122 to move. Temperature sensors 123 are installed on the left and right fixed plates 12. The temperature sensor 123 is electrically connected to the stepper motor 127 through a control module.

[0033] When the broccoli seedlings are exposed to sunlight from the outside, the temperature sensor 123 monitors the external temperature. When the temperature sensor 123 detects that the temperature exceeds the maximum value that the broccoli seedlings can withstand, the temperature sensor 123 controls the left stepper motor 127 to reverse and the right stepper motor 127 to rotate forward through the control module. The forward rotation of the right stepper motor 127 drives the right rotating rod 126 to rotate forward. The forward rotation of the right rotating rod 126 drives the right rotating plate 124 to swing backward. The backward swing of the right rotating plate 124 drives the front driving rod 125 to swing backward. The backward swing of the front driving rod 125 drives the head end of the front sunshade cloth 122 to move backward, so that the front sunshade cloth 122 is pulled out and drives the front winding roller 121 to rotate forward. The front volute spring 1221 is compressed, and the front sunshade cloth 122 contacts the front and rear guide shells 2 and is supported and limited. The front sunshade cloth 122 covers the broccoli seedlings. At this time, the left stepper motor 127 reverses and drives the left rotating rod 126 to reverse. The left rotating rod 126 reverses and drives the left rotating plate 124 to swing forward. The left rotating plate 124 swings forward and drives the rear sunshade cloth 122 to swing forward through the rear driving rod 125. The rear sunshade cloth 122 swings forward and drives the rear winding roller 121 to reverse. The rear sunshade cloth 122 covers the broccoli seedlings. Since the lengths of the left and right rotating plates 124 are different, the swinging of the front and rear sunshade cloths 122 will not interfere with each other. After the front and rear driving rods 125 are rotated one hundred and eighty degrees, the stepper motor 127 is turned off. At this time, the front and rear sunshade cloths 122 can block the sunlight and reduce the exposure of the broccoli seedlings. At the same time, the position where the front and rear sunshade cloths 122 contact each other is above the broccoli seedlings, which makes the broccoli seedlings doubly protected, and the effect of blocking sunlight is better. When the temperature sensor 123 detects that the external temperature has dropped to the set standard value, the temperature sensor 123 controls the left stepper motor 127 to rotate forward and the right stepper motor 127 to rotate reversely through the control module, which causes the right rotating plate 124 to drive the front driving rod 125 to swing forward and reset. The front driving rod 125 drives the head end of the front sunshade cloth 122 to swing forward and reset. The front sunshade cloth 122 is relaxed. Due to the action of the spiral spring 1221, the front winding roller 121 reverses and rewinds the front sunshade cloth 122. Similarly, the rear driving rod 125 drives the head end of the rear sunshade cloth 122 to swing backward and reset. Due to the action of the rear spiral spring 1221, the rear winding roller 121 rotates forward and rewinds the sunshade cloth 122. In this way, the broccoli seedlings can be prevented from being exposed to the sun in a high temperature environment and causing death, thereby ensuring the safe growth of the broccoli seedlings.

[0034] See also Figure 8 As shown, the broccoli seedling raising device also includes a scraper 13. The scraper 13 is fixed to the side of the front and rear fixed plates 12 that are away from each other. The scraper 13 is in contact with the sunshade cloth 122, and the scraper 13 can scrape off impurities attached to the sunshade cloth 122.

[0035] See also Figure 9 As shown, the broccoli seedling raising device also includes a limiting bar 14 and a filter plate 15. The limiting bars 14 are fixedly connected to the lower parts of the left and right side surfaces of the placement frame 4. The filter plate 15 is placed between the left and right limiting bars 14. The filter plate 15 is located in the placement frame 4. The filter plate 15 can filter the fallen soil.

[0036] When the sunshade cloth 122 is rolled up by the winding roller 121, the scraper 13 can scrape off the impurities attached to the sunshade cloth 122. This can prevent the sunshade cloth 122 from being corroded by a large amount of impurities and affecting subsequent normal use, thereby improving the service life of the sunshade cloth 122.

[0037] When the broccoli seedlings are being grown, the filter plate 15 can block the soil that falls during the growing process. When the seedling pot is taken out of the placement frame 4, the filter plate 15 is taken out of the placement frame 4 to process the filtered soil, and then the filter plate 15 is put back into the placement frame 4 to be restrained by the limiting strips 14. In this way, the soil that falls can be prevented from mixing with the water in the placement frame 4 and affecting the subsequent use of the water, thereby ensuring the normal use of the water in the placement frame 4.

[0038] Finally, it is necessary to point out that the above content is only used to help understand the technical solution of the present invention and cannot be understood as limiting the scope of protection of the present invention; non-essential improvements and adjustments made by technical personnel in this field based on the above content of the present invention are all within the scope of protection required by the present invention.
