The soaking structure 22 is connected to the soil storage structure 24. It is used for soaking lettuce vegetable seeds to be planted. When the soaking structure 22 is taken out, the vegetable seeds that have been soaked inside will automatically fall into the seedling cultivation structure 26 as the soaking structure 22 is removed. It also includes a rotating structure 25 for adjusting the seedling cultivation structure 26. The seedling cultivation structure 26 can be adjusted by the rotating structure 25, so that the seedlings on the seedling cultivation structure 26 are separated from its surface and the soil at the roots is tightened to avoid the soil at the roots of the seedlings from being scattered, which leads to a decrease in their survival rate after planting.

[0054] like Figures 2 to 6As shown, the seedling tube 21 is formed by connecting a seedling section 211, a diameter-changing section 212 and a moisture-retaining section 213. The two ends of the diameter-changing section 212 are fixedly connected to the seedling section 211 and the moisture-retaining section 213 respectively, wherein the diameter of the seedling section 211 is larger than the diameter of the moisture-retaining section 213, and the diameter-changing section 212 is used to connect the seedling sections 211 and the moisture-retaining section 213 of different diameters; a plurality of drainage holes 219 are provided at the bottom of the moisture-retaining section 213, and the drainage holes 219 are used to drain the water soaking the vegetable seeds in the seed-soaking structure 22; the outer wall of the moisture-retaining section 213 is fixedly connected with a second ring 216, and the second ring 216 is adaptively connected to the first ring 13. The seedling tube 21 is fixedly connected to the breeding disc 12 through the second ring 216 and the first ring 13. The cooperation between the first ring 13 and the second ring 216 makes it easy to place and disassemble the seedling tube 21; the diameter-changing section 21 2 is provided with a plurality of drainage and ventilation grooves 215 penetrating therethrough, and the drainage and ventilation grooves 215 are used to ventilate the seedling culture structure 26, increase the air permeability of the roots of the vegetable seedlings, and thus provide a better growth environment for the plants; a first slide groove 217 is provided on the outer wall of the seedling section 211, and second slide grooves 218 symmetrical to each other are provided on both sides of the first slide groove 217, and the first slide groove 217 and the second slide groove 218 are in a cross-shaped structure, wherein the first slide groove 217 and the second slide groove 218 provide an installation position for the rotating structure 25, and the first slide groove 217 is provided with a plurality of through holes 214 penetrating the seedling section 211, and the positions of the plurality of through holes 214 correspond to the positions of the plurality of drainage and ventilation grooves 215, and a convex plate 27 is placed at the bottom of the moisturizing section 213, and a plurality of air permeable grooves distributed in an annular shape are provided on the convex plate 27, wherein the convex plate 27 is the prior art.

[0055] like Figure 5 , Fig.17 , Fig.19 and Fig. 20As shown, the seedling culture structure 26 is composed of a plurality of culture strips 261 evenly arranged in a ring shape, with a gap between every two culture strips 261, the culture strips 261 are an integrally formed structure, and the plurality of culture strips 261 are distributed in a funnel shape inside the seedling tube 21, and the gap between every two culture strips 261 allows each culture strip 261 to move independently; the culture strip 261 is formed by connecting a deformation section 2611, a connecting section 2612 and a culture section 2613, the deformation section 2611 is an elastic sheet structure, and the connecting section 2612 is used to support the culture section 2613, and in the initial state, the plurality of culture sections 2613 are offset toward the central end under the elastic force of the deformation section 2611, so that the connection positions of every two adjacent culture sections 2613 and the connecting section 2612 are pressed and fitted against each other, The bottom end of the deformation section 2611 is fixedly connected to the connection position between the moisturizing section 213 and the variable diameter section 212, the top end of the deformation section 2611 is fixedly connected to the bottom end of the connecting section 2612, the top end of the connecting section 2612 is fixedly connected to the culture section 2613, and a plurality of through-feeding grooves 263 are provided on the culture section 2613. The faecal extraction grooves 263 are used to drain and ventilate the soil on the culture section 2613, while reducing the contact area between the soil and the culture section 2613, so as to facilitate the separation of the culture section 2613 from the soil at a later stage. A traction block 262 is fixedly connected to the surface wall of the culture section 2613 at a position corresponding to the perforation 214, and a plurality of culture sections 2613 are arranged in a ring to form a semicircular structure, and a plurality of culture sections 2613 of the semicircular structure can be matched with the bottom of the seed soaking structure 22.

[0056] like Figure 4 , Figure 6 , Fig.17 and Fig.18 As shown, the rotating structure 25 includes a traction slip ring 254 rotatably connected to the seedling section 211. The T-shaped traction slip ring 254 is adaptably connected to the first slide groove 217 and the second slide groove 218. There is a rotation gap between the inner surface wall of the traction slip ring 254 and the inner wall of the first slide groove 217. The width of the rotation gap is greater than the diameter of the pull rope 252. The rotation gap is used to provide a moving space for the pull rope 252. The inner wall of the traction slip ring 254 is fixedly connected with a plurality of pull ropes 252. Each pull rope 252 passes through the through hole 214 and extends to the inside of the seedling section 211 and is fixedly connected to the traction block 262. The outer wall of the traction slip ring 254 is fixedly connected with an operating turntable 251. The outer wall of the operating turntable 251 is fixedly connected with a plurality of evenly arranged anti-slip convex strips 253.

[0057] The staff rotates the operating turntable 251 to drive the traction slip ring 254 fixedly connected thereto to rotate in the first slide groove 217 and the second slide groove 218. The rotating traction slip ring 254 will drive the pull rope 252 to move in the rotating gap. The pull rope 252 pulls the traction block 262 fixedly connected thereto, thereby driving the culture segment 2613 and the connecting segment 2612 to shift outward under the deformation of the deformation segment 2611. When the staff releases the operating turntable 251, the deformation segment 2611 begins to recover its deformation without the traction force of the pull rope 252, driving the culture segment 2613 and the connecting segment 2612 to return to their initial positions.

The gap between the connecting tube 242 and the connecting tube 241 is connected to the interior of the seedling section 211. The clamping tube 242 is used to install the seed soaking structure 22, so that the seed soaking structure 22 can be detachably connected to the clamping tube 242. The inner wall of the clamping tube 242 is provided with four L-shaped grooves 243, and each two adjacent L-shaped grooves are distributed in a circular manner at 90°. The bottom of the L-shaped groove 243 is fixedly connected with a plurality of evenly arranged anti-slip strips 244. The embedded tube 221 is fixed to the clamping tube 242 through the cooperation of the L-shaped groove 243 and the block 222. The stability of the block 222 in the L-shaped groove 243 is increased by the adaptation of the anti-slip strip 244 and the anti-slip groove 223.

[0059] like Figure 3 , Figure 4 , Figures 11 to 16As shown, the foam structure 22 includes an embedded tube 221 connected to the inner wall of the clamping tube 242, and the outer wall of the embedded tube 221 is fixedly connected with four clamping blocks 222, and each two adjacent clamping blocks are distributed in a ring shape at 90 degrees. The bottom of the clamping block 222 is provided with an anti-skid groove 223 adapted to the anti-skid strip 244, and the bottom of the embedded tube 221 is fixedly connected with a plurality of sealing pieces 225, and the plurality of sealing pieces 225 are distributed in a ring shape at the bottom of the embedded tube 221, and the plurality of sealing pieces 225 are initially unfolded with each other; a rubber convex strip 2251 is fixedly connected to the surface of one side of the sealing piece 225, and a rubber convex strip 2251 is fixedly connected to the surface of the other side of the sealing piece 225 There is a convex groove 2252 adapted to the rubber convex strip 2251, and every two adjacent sealing pieces 225 are sealed by the rubber convex strip 2251 and the convex groove 2252; the inner surface wall of the embedded tube 221 close to the sealing piece 225 is connected with a seed placement unit 224, and the seed placement unit 224 includes a mounting block 2241 fixedly connected to the inner surface wall of the embedded tube 221, and a rotating rod 2242 is rotatably connected to the mounting block 2241, and one end of the rotating rod 2242 is fixedly connected to a seed placement disk 2243, and the seed placement disk 2243 and the rotating rod 2242 are both made of foam material, and a horizontally arranged blocking rod 2244 is fixedly connected to the surface of one side of the mounting block 2241.

[0060] When installing the bubble seed structure 22, align the block 222 on the surface wall of the embedded tube 221 with the L-shaped groove 243 and insert it into the clamping tube 242. When the block 222 slides to the bottom of the L-shaped groove 243, rotate the embedded tube 221 so that the block 222 slides on the bottom of the L-shaped groove 243. While sliding, the anti-slip groove 223 at the bottom of the block 222 fits with the anti-slip strip 244 to prevent the block 222 from deviating and sliding on the L-shaped groove 243. When the block 222 slides into the bottom of the L-shaped slide groove 243, the plurality of sealing sheets 225 are slowly inserted into the ring-shaped culture section 2613, and the culture section 2613 squeezes the sealing sheets 225, so that the plurality of sealing sheets 225 fit together under the squeezing of the culture section 2613. When fitting together, every two adjacent sealing sheets 225 are sealed by the rubber convex strips 2251 and the convex strip grooves 2252, and the plurality of sealing sheets 225 are sealed to each other. The embedded tube 221 is in contact with the surface of the culture section 2613. When the vegetable seeds are soaked, water is injected into the inner tube 221. Under the buoyancy of the water, the seed tray 2243 begins to rotate on the mounting block 2241 until it is limited by the blocking rod 2244 and rotates to a horizontal position to place the vegetable seeds on the seed tray 2243. When the soaking is completed, the embedded tube 221 is rotated so that the embedded tube 221 can be pulled out from the clamping tube 242. During the pulling out process, the sealed sheet 225 slowly rises, and the squeezing pressure of the culture section 2613 on the sealed sheet 225 gradually decreases. Several sealed sheets 225 begin to unfold, so that the soaking water inside the embedded tube 221 can flow out. As the soaking water gradually flows out, the buoyancy of the internal soaking water on the seed tray 2243 gradually decreases until all the soaking water flows out, and the seed tray 2243 falls, and the vegetable seeds inside fall from the seed tray 2243 into the seedling culture structure 26.

[0061] like Figure 3 , Fig.11 ,and Fig.12 As shown, a loosening piece 23 is fixedly connected to the top of the outer wall of the embedded tube 221, and a plurality of evenly arranged semi-circular balls 231 are fixedly connected to the outer wall of the loosening piece 23. The semi-circular balls 231 can loosen the nutrient soil between the connecting tube 241 and the clamping tube 242. When the nutrient soil is stuck in the connecting tube 241 and the clamping tube 242 and cannot fall off, a visual groove 232 is provided at the top of the loosening piece 23 corresponding to the block 222. The visual groove 232 is convenient for the staff to observe the position of the block 222 and the L-shaped slide groove 243, and the shape of the loosening piece 23 is adapted to the outer wall of the clamping tube 242. When the embedded tube 221 is inserted into the clamping tube 242, the loosening piece 23 slides in along the surface of the clamping tube 242 until the loosening piece 23 is completely fitted with the surface of the clamping tube 242.

[0062] The present application also provides a breeding method of a Lactuca vegetable breeding device, comprising the following steps:

[0063] S1, first install the seed foaming structure 22, install the seed foaming structure 22 on the soil storage structure 24, and at the same time slide the loosening piece 23 into the surface of the clamping tube 242;

[0064] S2, soaking the vegetable seeds, injecting water into the inner tube 221, and then placing the vegetable seeds on the seed tray 2243, and then pouring nutrient soil into the gap between the connecting tube 241 and the clamping tube 242;

[0065] S3, after the vegetable seeds are soaked, the embedded tube 221 is rotated to take them out, and while taking them out, the seeds fall onto the seedling culture structure 26, and the nutrient soil in the gap between the connecting tube 241 and the clamping tube 242 slides out onto the seedling culture structure 26, thereby completing the work of covering the seeds;

[0066] S4, when the vegetable seeds on the seedling cultivation structure 26 grow into seedlings, the staff rotates the operating turntable 251 to separate and compact the soil on the seedling cultivation structure 26;

[0067] S5. The staff takes out the seedlings from the seedling culture structure 26 and carries out planting.

[0068] The working principle of the technical solution provided by the present invention is as follows: first install the seed foam structure 22, align the block 222 on the surface wall of the embedded tube 221 with the L-shaped groove 243 and insert it into the clamping tube 242, and when the block 222 slides to the bottom of the L-shaped groove 243, rotate the embedded tube 221 so that the block 222 slides at the bottom of the L-shaped groove 243, and while sliding, the anti-slip groove 223 at the bottom of the block 222 fits with the anti-slip strip 244 to prevent the block 222 from sliding on the L-shaped groove 243. When the block 222 slides into the bottom of the L-shaped groove 243, a plurality of close The closing piece 225 will slowly get stuck into the ring-shaped culture section 2613, and the culture section 2613 squeezes the closing piece 225, so that several closing pieces 225 fit together under the squeezing of the culture section 2613. When fitting together, every two adjacent closing pieces 225 are adapted and sealed through the rubber convex strips 2251 and the convex strip grooves 2252. Several closing pieces 225 are sealed to each other and fit together with the surface of the culture section 2613. When the embedded tube 221 is inserted into the clamping tube 242, the loosening piece 23 slides in along the surface of the clamping tube 242 until the loosening piece 23 is completely fitted with the surface of the clamping tube 242.

[0069] When soaking the vegetable seeds, water is poured into the inner tube 221, and the seed tray 2243 begins to rotate on the mounting block 2241 under the buoyancy of the water until it rotates to a horizontal position under the limit of the stop rod 2244, and the vegetable seeds are placed on the seed tray 2243. When the soaking is completed, the inner tube 221 is rotated so that the inner tube 221 can be pulled out from the clamping tube 242. During the pulling out process, the sealing sheet 225 slowly rises, and the culture section 2613 is The squeezing pressure of the sealing sheet 225 gradually decreases, and several sealing sheets 225 begin to unfold, so that the soaking water inside the embedded tube 221 can flow out. As the soaking water gradually flows out, the buoyancy of the internal soaking water on the seed tray 2243 gradually decreases until all the soaking water flows out, the seed tray 2243 falls, and the vegetable seeds inside fall from the seed tray 2243 into the seedling cultivation structure 26, and then the nutrient soil is poured into the gap between the connecting tube 241 and the clamping tube 242.

[0070] After the vegetable seeds are soaked for 4-5 hours, the embedded tube 221 is rotated so that the embedded tube 221 can be pulled out from the clamping tube 242. During the pulling-out process, the sealed sheet 225 slowly rises, and the squeezing force of the culture section 2613 on the sealed sheet 225 gradually decreases. Several sealed sheets 225 begin to unfold, so that the soaking water inside the embedded tube 221 can flow out. When the embedded tube 221 is pulled out, the embedded tube 221 cancels the obstruction of the gap between the clamping tube 242 and the connecting tube 241, and the nutrient soil in the gap between the clamping tube 242 and the connecting tube 241 will slide onto the seedling culture structure 26 along the gap. As the soaking water gradually flows out, the buoyancy of the internal soaking water on the seed tray 2243 gradually decreases until all the soaking water flows out, the seed tray 2243 falls, and the vegetable seeds inside fall from the seed tray 2243 into the nutrient soil on the seedling culture structure 26, and are then covered by the nutrient soil that falls subsequently.

[0071] When the vegetable seeds on the seedling cultivation structure 26 grow into seedlings and need to be transplanted and planted, the staff rotates the operating turntable 251 to drive the traction slip ring 254 fixedly connected thereto to rotate in the first slide groove 217 and the second slide groove 218. The rotating traction slip ring 254 drives the pull rope 252 to move in the rotation gap. The pull rope 252 pulls the traction block 262 fixedly connected thereto, thereby driving the cultivation section 2613 and the connecting section 2612 to move outward under the deformation of the deformation section 2611. The culture section 2613 is offset, causing the culture section 2613 to separate from the nutrient soil. When the staff releases the operating turntable 251, the deformation section 2611 begins to recover its deformation without the traction of the pull rope 252, driving the culture section 2613 and the connecting section 2612 to return to their initial positions. The culture section 2613 that has returned to its initial position squeezes and tightens the nutrient soil under the elastic force of the deformation section 2611, so that the nutrient soil tightly wraps the vegetable seedlings. The staff can directly take the seedlings and carry out planting work.
