The traditional soil culture method is one of the most widely used seedling cultivation methods. This method is to lay seedling soil on the seedbed, plant seeds or seedlings in the soil, and cultivate seedlings by using the natural moisture retention and nutrient supply function of the soil. However, the existing soil seedling cultivation device has some shortcomings in practical applications and needs to be improved.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1, as Figure 1 As shown, a high-efficiency and energy-saving forestry seedling cultivation device includes a circulation box 1, a cultivation cabinet 2 is fixedly connected to the upper end of the circulation box 1, a plurality of full-spectrum fill lights 7 are linearly distributed and fixedly connected on the left and right sides of the inner cavity of the cultivation cabinet 2, a control cabinet 3 is fixedly connected to the upper end of the cultivation cabinet 2, a seedling cultivation structure 4 is commonly provided in the inner cavity of the cultivation cabinet 2 and the inner cavity of the control cabinet 3, a return water tray 5 is provided on the bottom wall of the inner cavity of the cultivation cabinet 2, and a spray structure 6 is symmetrically provided on the inner surface of the cultivation cabinet 2.

[0035] It should be noted that the above-mentioned control cabinet 3 is a conventional control device, which is provided with a number of circuit breakers and buttons for controlling the start and stop of electrical equipment. This structure has been widely used in the prior art. In the present invention, it is only used to realize the function of controlling the switch of the seedling structure 4, the spray structure 6, and the full-spectrum fill light 7. Its internal structure, operating principle, wiring, and control method will not be described in detail.

[0036] Further, in order to achieve the bearing and fixation of forest seedlings, see Figure 2 and Figure 3 The seedling raising structure 4 includes a motor 41 installed on the bottom wall of the inner cavity of the control cabinet 3. The output end of the motor 41 passes through the upper end of the cultivation cabinet 2 and extends to the inner cavity of the cultivation cabinet 2 and is connected to a transmission shaft 44. The outer surface of the transmission shaft 44 is linearly distributed and fixedly connected with a plurality of seedling raising components 43.

[0037] Motor 1 41 is used to drive the seedling raising assembly 43 to rotate slowly through the transmission shaft 44, and cooperate with the spray structure 6 and the full-spectrum fill light 7 to irrigate and fill light the forest seedlings. The effective area of ​​the spray structure 6 and the full-spectrum fill light 7 is increased by rotation, the use of related equipment is reduced, and energy-saving effects are achieved.

[0038] Further, to achieve convection circulation of air inside and outside, refer to Figure 2 and Figure 3 The inner surface of the control cabinet 3 is fixedly connected to a ventilator 42 connected to the outside, and the upper part of the outer surface of the transmission shaft 44 is rotatably connected to an air slip ring 421 fixedly connected to the top wall of the inner cavity of the cultivation cabinet 2. The inner cavity of the air slip ring 421 is connected to the inner cavity of the transmission shaft 44 through a through hole opened on the outer surface of the transmission shaft 44, and the inner cavity of the air slip ring 421 is connected to the inner cavity of the ventilator 42 through an air pipe. The outer surface of the transmission shaft 44 is located on the upper side of the adjacent seedling raising component 43 and is provided with a plurality of air outlet holes 422 connected to its inner cavity.

[0039] The seedlings need to consume carbon dioxide to generate oxygen through photosynthesis. Under long-term operation, although the oxygen inside the cultivation cabinet 2 can flow out under pressure, the carbon dioxide cannot be replenished, and the photosynthesis will be relatively weakened. A fan is installed inside the ventilator 42. The fan action sends the external air directly to the range of the forest seedlings through the air slip ring 421 and the air outlet 422. The efficiency of photosynthesis is further improved by replenishing carbon dioxide, thereby improving the growth efficiency of the seedlings and shortening the cultivation period.

[0040] Further, to achieve irrigation of tree seedlings, see Figure 2 and Figure 3 The spray structure 6 includes a water pump 61 installed on the bottom wall of the inner cavity of the control cabinet 3. The input end of the water pump 61 is fixedly connected to a water supply pipe 64 connected to the inner cavity of the circulation box 1. The output end of the water pump 61 is fixedly connected to a connecting pipe 62. The connecting pipe 62 is divided into two branches on the side away from the water pump 61 and extends to the left and right sides of the inner surface of the cultivation cabinet 2 respectively. The part of the inner surface of the cultivation cabinet 2 on the upper side of the adjacent seedling raising component 43 is symmetrically fixedly connected with a spray pipe 63 connected to the adjacent connecting pipe 62.

[0041] The water in the circulation box 1 is extracted through the water pump 61 and the water supply pipe 64. The interior of the circulation box 1 can also be filled with inorganic water fertilizer mixed with nutrient solution. The water pump 61 extracts the liquid and sends it into the connecting pipe 62, and then sends it to the spray pipe 63 through the connecting pipe 62 to spray the forest seedlings, thereby realizing automatic irrigation of the forest seedlings.

[0042] During the operation of this embodiment, the motor 41 and the transmission shaft 44 are used to drive the seedling raising component 43 to rotate slowly, and the rotation effect is used to increase the effective area of ​​the spray structure 6 and the full-spectrum fill light 7, thereby reducing the use of related equipment and achieving energy-saving effects. The ventilator 42 is used to transport air inward, and the air pressure is used to discharge the oxygen generated by photosynthesis and further improve the efficiency of photosynthesis by supplementing carbon dioxide, thereby improving the growth efficiency of the seedlings, shortening the cultivation period, and improving the seedling raising efficiency.

[0043] Embodiment 2. Based on embodiment 1, this embodiment isolates the sewage seeping from the seedling basin 434 through the action of the water retaining plate 432, and fixes the seedling basin 434 in the mounting hole when the seedling basin 434 is inside the mounting hole by utilizing the action of the fixing component 433, so as to avoid shaking during the rotation of the seedling basin 431 due to centrifugal force or the spraying action of the spray pipe 63, thereby ensuring the stability of the seedling basin 434 and the forest seedlings therein, and simultaneously, utilizing the action of the compression rod 4337 and the fixed slider 4334 to facilitate the removal of the seedling basin 434 during the subsequent transplanting process.

[0044] Specifically, in order to achieve the bearing and fixation of forest seedlings, refer to Figure 4 The seedling raising component 43 includes a water retaining plate 432 fixedly connected to the outer surface of the transmission shaft 44. The outer surface of the transmission shaft 44 located on the upper side of the water retaining plate 432 is fixedly connected to a seedling raising plate 431 with a plurality of mounting holes connected up and down. Seedling raising pots 434 are placed on the inner surfaces of the plurality of mounting holes. The inner surfaces of the plurality of mounting holes on the seedling raising plate 431 are provided with fixing parts 433 distributed in a ring shape relative to the center of the seedling raising pot 434.

[0045] The seedling basin 434 is a conventional transplanting basin for cultivation, and a hole for water control is opened at the bottom thereof. The fixing component 433 is used to fix the seedling basin 434 and fix it in the installation hole; the water retaining plate 432 is used to block the sewage seeping out of the seedling basin 434, thereby preventing these impurity water from entering the seedling basin 434 at the lower layer.

[0046] Further, in order to achieve the clamping and fixing of the seedling pot 434, refer to Figure 5 and Figure 6The fixing component 433 includes a cross slide groove 4332 opened on one side of the seedling basin 434 near the mounting hole, and the inner surface of the cross slide groove 4332 is symmetrically provided with obliquely distributed oblique slide grooves 4333 along its center point, and the inner surface of the cross slide groove 4332 is slidably connected with a driving slider 4335, and the upper end of the driving slider 4335 is slidably connected with a driving block 4336 slidably connected to the inner surfaces of the oblique slide grooves 4333 on both sides. The upper end of the driving block 4336 is fixedly connected to a fixed slider 4334 slidably connected to the upper end of the seedling tray 431 through a telescopic rod, and the lower end of the seedling tray 431 is rotatably connected to an L-shaped clamp arm 4331 that is tightly attached to the outer surface of the seedling basin 434, and the lower end of the driving slider 4335 is fixedly connected to a contact rod 4330 that is tightly attached to the upper end of the L-shaped clamp arm 4331, and the lower end of the driving slider 4335 is fixedly connected to the bottom wall of the inner surface of the cross slide groove 4332, and a compression spring sleeved on the outer surface of the contact rod 4330 is fixedly connected.

[0047] First, after the seedling basin 434 enters the installation hole, it will support the L-shaped clamp arm 4331 and make its horizontal part gradually approach the seedling tray 431, and drive the driving slider 4335 to rise along the cross slide groove 4332 through the contact rod 4330, and push the driving block 4336 to rise, and under the action of the inclined slide groove 4333, drive the driving block 4336 to approach the seedling basin 434, and then drive the fixed slider 4334 to approach the seedling basin 434, clamping and fixing the seedling basin 434.

[0048] Further, in order to facilitate the removal of the seedling pot 434, refer to Figure 7 The upper side of the fixed slider 4334 is concave and its inner surface is rotatably connected to a compression rod 4337. The left and right sides of the compression rod 4337 are linearly distributed and fixedly connected to a number of limiting protrusions 4339. The lower end of the compression rod 4337 is close to the seedling basin 434 and the side of the fixed slider 4334 is close to the seedling basin 434 and is fixedly connected to an elastic pull rope 4338.

[0049] By pulling the seedling basin 434 upward, when the force is greater than a certain value, the pressing rod 4337 can overcome the friction between the limiting protrusion 4339 and the fixed slider 4334, and the limiting protrusion 4339 is disengaged from the fixed slider 4334, and the pressing rod 4337 can rotate, thereby facilitating the removal of the seedling basin 434 from the installation hole;

[0050] Furthermore, after taking out, the compression rod 4337 is reset under the action of the elastic pull rope 4338, and synchronously, due to the lack of support of the L-shaped clamp arm 4331, the contact rod 4330 moves downward under the action of the spring, and drives the driving slider 4335 to move downward. The driving block 4336 follows the driving slider 4335 to descend, thereby causing the fixed slider 4334 to move to the side away from the mounting hole, thereby facilitating the subsequent loading of the seedling pot 434.

[0051] Embodiment 3: Based on embodiment 2, this embodiment further sends the water seeping from the seedling basin 434 back to the circulation box 1 through the water guide groove 51 and the connecting hole 52 opened at the bottom of the cultivation cabinet 2, and sends it back to the bottom of the circulation box 1 after being filtered by the filter screen 11, and performs secondary circulation through the water supply pipe 64 and the water pump 61. Furthermore, the cleaning component 14 and the T-shaped slide groove 13 cooperate to drive the silicone scraper 145 to slide on the upper side of the filter screen 11, and push the soil and impurities on the upper part into the garbage box 12 for temporary storage, so as to avoid blockage of the upper part of the filter screen 11, extend the maintenance cycle, and reduce the waste of water resources.

[0052] Specifically, to realize the recycling of water, see Figure 8 The return water tray 5 includes a plurality of water guide grooves 51 linearly distributed on the bottom wall of the inner cavity of the cultivation cabinet 2 , and a plurality of connecting holes 52 connected to the inner cavity of the circulation box 1 are linearly distributed on the bottom wall of the inner surface of the plurality of water guide grooves 51 .

[0053] Further, to filter the returned water, see Fig. 9 A filter screen 11 is fixedly connected to the upper inner surface of the circulation box 1, and a T-shaped slide groove 13 is symmetrically provided on the inner surface of the circulation box 1 located above the filter screen 11. A garbage box 12 is slidably connected to the inner surface of the circulation box 1 located below the filter screen 11, and a cleaning component 14 is slidably connected to the inner surfaces of the two T-shaped slide grooves 13.

[0054] The filter screen 11 is used to filter impurities such as soil and scum in the return water. The water returns to the lower part of the circulation box 1, and the impurities remain on the upper part of the filter screen 11.

[0055] Further, in order to clean the filter 11, refer to Fig.10 The cleaning component 14 includes a conical block 141, and the left and right sides of the conical block 141 are fixedly connected with limit blocks 143 that are slidably connected to the adjacent T-shaped slide grooves 13, and the ends of the two limit blocks 143 that are away from each other are fixedly connected with pulleys 142 on the inner surfaces of the adjacent T-shaped slide grooves 13, and the inner surface of the conical block 141 is fixedly connected with a motor 144 that is transmission-connected to the adjacent pulley 142, and the lower end of the conical block 141 is linearly distributed and fixedly connected with a plurality of silicone scrapers 145 that are closely attached to the upper end of the filter screen 11.

[0056] During the cleaning process, first, under the action of the control console on the control cabinet 3, the spray structure 6 stops spraying, and the limit blocks 143 on both sides of the conical block 141 will slide in the T-shaped slide groove 13, limiting the rotation of the conical block 141 due to other forces. Furthermore, the motor 2 144 that has been secretly rotated inside the conical block 141 drives the pulley 142 to rotate in the T-shaped slide groove 13, thereby driving the conical block 141 to move on the filter screen 11. The silicone scraper 145 at the bottom of the conical block 141 can scrape the impurities on the top of the filter screen 11 and push them into the garbage box 12.
