DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 12 The present invention provides a technical solution: a ginkgo soilless seedling raising device based on smart agriculture, comprising a frame 1 and a nutrient solution pool 2 located at the bottom of the frame 1, a plurality of liquid storage tanks 3 are installed on the frame 1; the bottom of the liquid storage tank 3 is open and a cultivation box 4 is fixedly installed on the inner side; a liquid taking mechanism is arranged in the liquid storage tank 3, a first driving mechanism is installed on the frame 1, and the first driving mechanism is used to drive the plurality of liquid storage tanks 3 and the cultivation box 4 to circulate; a second driving mechanism is also installed on the frame 1, and the second driving mechanism is used to drive the liquid taking mechanism to absorb the nutrient solution in the nutrient solution pool 2 and transport it to the liquid storage tank 3 when the liquid storage tank 3 moves above the nutrient solution pool 2, and transport the nutrient solution to the cultivation box 4 during the circulation of the liquid storage tank 3.

[0019] When the staff is carrying out the preparation work before seedling cultivation, they first fill the cultivation box 4 with a cultivation matrix (such as a mixture of perlite, vermiculite, coconut bran, etc.), then add a sufficient amount of nutrient solution to the nutrient solution pool 2, and then plant the broken ginkgo seeds into the matrix in the cultivation box 4; the first driving mechanism will drive multiple liquid storage tanks 3 and cultivation boxes 4 to move in a circular motion; when the liquid storage tanks 3 and cultivation boxes 4 move to the top of the nutrient solution pool 2, the second driving mechanism will drive the liquid taking mechanism in the liquid storage tank 3 to move to the nutrient solution pool 2 to absorb a certain amount of nutrient solution, and transport the nutrient solution to the liquid storage tank 3 for storage; during the subsequent circular movement of the liquid storage tank 3 and cultivation box 4, the second driving mechanism can drive the liquid taking mechanism to transport the nutrient solution in the liquid storage tank 3 to the cultivation box 4 to provide nutrition for the growth of ginkgo seeds.

[0020] Specifically, Figure 3 , Figure 4 , Fig.10 and Fig.11 As shown, the liquid taking mechanism includes two first chutes 5, two first slide plates 6 and a liquid taking block 7; the two first chutes 5 are symmetrically opened on the inner wall of the liquid storage tank 3; the first chute 5 is set to be "L"-shaped, and the horizontal section is set to be inclined; the two first slide plates 6 are both located on the inner side of the liquid storage tank 3, are arranged symmetrically, and the side walls are fixedly installed with first guide columns 8; the two first guide columns 8 are respectively slidably matched with the two first chutes 5; the liquid taking block 7 is installed on the top of the first slide plate 6 and can absorb nutrient solution; the liquid taking block 7 is made of absorbent sponge material.

[0021] When the liquid storage tank 3 and the cultivation box 4 move to the top of the nutrient solution pool 2, the second driving mechanism will drive the first slide plate 6 to move downward in the liquid storage tank 3, and the first slide plate 6 will drive the liquid taking block 7 to move downward synchronously; Fig.11 As shown, under the cooperation of the first slide 5 and the first guide column 8, the first slide plate 6 will move downward for a short distance (that is, the left and right ends of the first slide plate 6 move to the lower part of the left and right side walls of the liquid storage tank 3), and will move downward and outward at the same time; the two first slide plates 6 will move away from each other, and the middle position of the two first slide plates 6 will be opened, and the first slide plate 6 will be immersed in the nutrient solution pool 2 together with the liquid collection block 7, and the liquid collection block 7 made of absorbent sponge material will absorb the nutrient solution; before the liquid storage tank 3 and the cultivation box 4 move to the outside of the nutrient solution pool 2, the second drive The driving mechanism will drive the first slide plate 6 to drive the liquid taking block 7 to move upward and back into the liquid storage tank 3. At this time, the two first slide plates 6 cooperate to close the bottom end of the liquid storage tank 3; the nutrient solution absorbed by the liquid taking block 7 is stored in the liquid storage tank 3; it should be noted that when the first slide plate 6 and the liquid taking block 7 are immersed in the nutrient solution pool 2, the liquid level of the nutrient solution should be located between the top surface of the first slide plate 6 and the top surface of the liquid taking block 7. While the liquid taking block 7 can absorb the nutrient solution, it can also ensure that the matrix that falls on the top surface of the liquid taking block 7 will not fall into the nutrient solution pool 2 and pollute the nutrient solution; During the subsequent movement of the liquid storage tank 3 and the cultivation box 4, the second driving mechanism will drive the first slide plate 6 to move upward, and the upward movement of the first slide plate 6 will squeeze the liquid taking block 7. Under the squeezing action, the nutrient solution in the liquid taking block 7 can enter the cultivation box 4 from the through hole at the bottom of the cultivation box 4 for absorption by the ginkgo seeds; when the liquid taking block 7 is squeezed, part of the nutrient solution will fall into the liquid storage tank 3. When the second driving mechanism does not act on the first slide plate 6, the liquid taking block 7 is in a relaxed state, and at this time, the liquid taking block 7 can squeeze the nutrient solution into the liquid storage tank 3 again. Absorb it, and then wait for the next time the second driving mechanism drives the first slide plate 6 to move upward again; it should be noted that the top surface of the first slide plate 6 and the liquid taking block 7 can be set to be concave, and the substrate and nutrient solution falling from the cultivation box 4 can flow to the middle position of the liquid taking block 7. When the first driving mechanism drives the first slide plate 6 to move downward to squeeze the liquid taking block 7, the nutrient solution can better enter the cultivation box 4, and the substrate can be better prevented from falling into the nutrient solution pool 2. At the same time, the nutrient solution can also be fully absorbed by the ginkgo seeds.

[0022] Specifically, Figure 4 , Figure 5 , Fig.10 and Fig.11 As shown, two liquid taking blocks 7 are provided, the two liquid taking blocks 7 are symmetrically arranged and are respectively slidably connected to the two first slides 6; the two liquid taking blocks 7 are connected by an elastic member 9; an insertion rod 10 is elastically and slidably connected to the first slide 6, and a socket 11 that can cooperate with the insertion rod 10 is provided on the liquid taking block 7; the elastic member 9 is provided as an elastic rope.

[0023] After the ginkgo seeds have grown to a certain period in the seedling stage, they need to be transplanted to a larger container for growth. The substrate in the cultivation box 4 can be reused after being washed with water. In this embodiment, after the ginkgo seedlings in the cultivation box 4 are taken out, the insertion rod 10 is inserted into the insertion hole 11 (which can be operated by parts such as the push rod), and the liquid collection block 7 is relatively fixed to the first slide 6. At this time, the nutrient solution pool 2 at the bottom of the frame 1 can be replaced with a cleaning pool. After the first driving mechanism drives the liquid storage tank 3 and the cultivation box 4 to rotate above the cleaning pool, the second driving mechanism will drive the first slide 6 and the liquid collection block 7 to move to Fig.12 In the position shown, the first slide plate 6 and the liquid collection block 7 are both in the open state, and then the staff can rinse the substrate with clean water from the top of the cultivation box 4, and the sewage can flow out from the through hole at the bottom of the cultivation box 4. At this time, the liquid collection block 7 is in the open state, and the sewage will not fall onto the liquid collection block 7 and pollute the liquid collection block 7; when cleaning the substrate, there is no need to pour the substrate out of the cultivation box 4, which can greatly improve the cleaning efficiency of the substrate.

[0024] Specifically, Figure 6-Figure 9 As shown, the cultivation box 4 is composed of a bottom plate 12 and four vertical plates 13, and a through hole is opened on the bottom plate 12; the four vertical plates 13 are respectively hinged on the four sides of the top of the bottom plate 12; the four vertical plates 13 cooperate with the bottom plate 12 and the liquid storage tank 3 to form a rectangular seedling area with an open top; bevel gears 14 are installed on the hinge shafts of the four vertical plates 13, and the bevel gears 14 on two adjacent vertical plates 13 are in a meshing state; the vertical plates 13 on the left and right sides are hinged with elastic telescopic rods 15, and the elastic telescopic rods 15 are hinged at one end away from the vertical plates 13 A slider 16, the first slider 16 is elastically slidably connected to the liquid storage tank 3 in the vertical direction; a first slide bar 17 capable of driving it to move downward is arranged on the side of the first slider 16, the first slide bar 17 is movably connected to the liquid storage tank 3 and the top end extends to the top of the liquid storage tank 3; a push rod 18 is fixedly connected to the bottom end of the first slide bar 17, a push block 19 capable of driving it to move is arranged on the side of the push rod 18, and the push block 19 is fixedly connected to the first slide plate 6; a wedge block 20 is fixedly connected to the insertion rod 10, and the wedge block 20 is located on the side of the push rod 18.

[0025] When the ginkgo seeds grow to a certain period in the seedling stage and need to be transplanted into a larger container for growth, Fig. 9As shown, the staff pushes the first slide bar 17 from the top of the liquid storage tank 3 to the side close to the push block 19, and the first slide bar 17 will drive the push rod 18 to move synchronously, and the push rod 18 will move to the inner side of the push block 19; the push rod 18 will also drive the wedge block 20 to move downward during the movement, and the wedge block 20 will drive the insertion rod 10 to move downward and insert into the insertion hole 11, so that the liquid collection block 7 and the first slide plate 6 are relatively fixed; during the downward movement of the first slide plate 6, the push rod 18 and the first slide bar 17 will be driven downward through the push block 19, and the first slide bar 17 will drive the first slide block 16 to move downward synchronously; as shown in FIG. Fig.12 As shown, the first slider 16 will drive the vertical plates 13 on the left and right sides to rotate outwards through the elastic telescopic rod 15. When the vertical plates 13 on the left and right sides rotate outwards, they will drive the vertical plates 13 on the front and rear sides to rotate outwards synchronously through the bevel gear 14; after the four vertical plates 13 rotate outwards, the volume of the cultivation box 4 increases, and the matrix will spread outwards, and the ginkgo seedlings planted in the matrix can be automatically exposed, which can facilitate the staff to pull out the ginkgo seedlings. At the same time, the spread matrix can also be more convenient to clean.

[0026] Specifically, Fig. 9 As shown, a block 21 for limiting the movement of the first slide bar 17 is inserted into the top of the liquid storage tank 3; the setting of the block 21 can ensure that the first slide bar 17 will not shake at will.

[0027] Specifically, Figure 2 and Fig.10 As shown, the second driving mechanism includes a second slider 22 and a plurality of driving blocks 23; the second slider 22 is slidably connected to the liquid storage tank 3 in the vertical direction, and the first slide plate 6 is slidably connected to the second slider 22 in the horizontal direction; the second slider 22 is fixedly connected to the second slide bar 25 by a traction rope 24, and the second slide bar 25 is elastically slidably connected to the liquid storage tank 3 in the horizontal direction, and when the second slide bar 25 moves horizontally, it can drive the second slider 22 to move vertically through the traction rope 24; the second slider 22 and the second slide bar 25 are both installed with a second guide column 26; a plurality of driving blocks 23 are evenly distributed on the frame 1, and the driving blocks 23 are each provided with an arc-shaped guide groove 27, and the second guide column 26 slides in cooperation with the guide groove 27.

[0028] First, when the first driving mechanism drives the liquid storage tank 3 to move to the top of the nutrient solution pool 2, the second guide column 26 on the second slider 22 will be inserted into the guide slot 27 in the lowest driving block 23. Under the action of the guide slot 27, the second guide column 26 will drive the second slider 22 to move downward, and the second slider 22 will drive the first slide plate 6 to move downward. In the growth stage of ginkgo seeds, the first slide plate 6 will drive the liquid collection block 7 to move to the position as shown in the figure. Fig.11 After the ginkgo seedlings are transplanted, the first slide 6 will drive the liquid block 7 to move to the state shown in FIG. Fig.12 The state shown is convenient for cleaning the substrate in the cultivation box 4; Fig.10 As shown, when the liquid taking block 7 moves to the lowest position to absorb the nutrient solution, when the first driving mechanism drives the liquid storage tank 3 to continue to move, the guide slide 27 drives the second slide block 22 to move upward back to the inside of the liquid storage tank 3 to close the liquid storage tank 3; in the subsequent process in which the first driving mechanism drives the liquid storage tank 3 to move in a circular manner, the driving block 23 at other positions can drive the first slide block 6 to move upward to squeeze the liquid taking block 7 through the second slide block 22; Fig.10 As shown, the guide grooves 27 on the driving blocks 23 on the left and right sides can cooperate with the second guide blocks 26 on the second slide bar 25 to drive the second slide bar 25 to move, so that the second slide bar 25 drives the second slider 22 to move upward through the traction rope 24; the guide grooves 27 on the top driving block 23 can cooperate with the second guide block 26 on the second slider 22 to drive the second slider 22 to move upward; in the process of the first driving mechanism driving the liquid storage tank 3 to move in a circular manner, the other driving blocks 23 except the bottom driving block 23 can drive the first slide plate 6 to intermittently move upward to squeeze the liquid taking block 7, so that the nutrient solution absorbed by the liquid taking block 7 can overflow into the cultivation box to provide nutrition for the growth of ginkgo seeds.

[0029] Specifically, Figure 1 As shown, the first driving mechanism includes a mounting ring 28, which is rotatably connected to the frame 1, and a motor capable of driving the mounting ring 28 to rotate is installed on the frame 1; a plurality of liquid storage tanks 3 are distributed in a circular array about the mounting ring 28 and are all installed on the inner side of the mounting ring 28; when working, the motor (not shown in the figure) can drive the plurality of liquid storage tanks 3 to circulate through the mounting ring 28, and the plurality of liquid storage tanks 3 can absorb nutrient solution intermittently.
