[0002] Dendrobium is a medicinal plant. Dendrobium seedlings are usually cultivated in cultivation beds using substrates, such as sphagnum moss, pine bark, sawdust, charcoal and wood blocks.

DETAILED DESCRIPTION

[0030] 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.

[0031] Reference Figure 1-Figure 8 A dendrobium seedling cultivation device comprises a cultivation bed 1, in which a plurality of cultivation boxes 2 (such as Figure 1 As shown), it should be noted that the cultivation box 2 is provided with dendrobium seedlings and a substrate for cultivating the dendrobium seedlings, which is the prior art.

[0032] The infusion mechanism includes a plurality of liquid inlet pipes 3 penetrating through the inner side walls of the plurality of incubators 2, the two ends of the liquid inlet pipes 3 are closed, and the inner wall of the liquid inlet pipes 3 located in the incubator 2 is symmetrically provided with a plurality of liquid outlet holes 5 (such as Figure 5 and Figure 6 As shown), one end of the liquid inlet pipe 3 located in the incubator 2 is fixedly connected to a conical head 4, and the side wall of the incubator 1 is provided with a plurality of grooves 6 corresponding to the plurality of liquid inlet pipes 3, and the inner walls of the plurality of grooves 6 are slidably connected to an L-shaped plate 7 (as shown Figure 2 As shown), a fixing ring 8 is fixedly connected to the upper end of the L-shaped plate 7, a first annular groove 9 is opened on the inner wall of the fixing ring 8, a rotatable ring 10 is sealingly and slidably connected to the inner wall of the first annular groove 9, and the side wall of the liquid inlet pipe 3 away from the conical head 4 is fixedly connected to the inner wall of the ring 10.

[0033] The cultivation bed 1 is provided with a moving mechanism for moving the L-shaped plate 7, the moving mechanism includes a U-shaped plate 27 fixedly connected to the side wall of the cultivation bed 1, the side wall of the U-shaped plate 27 is rotatably connected to a cross bar 14, the side wall of the cross bar 14 is fixedly connected to a plurality of gears 15 corresponding to the plurality of L-shaped plates 7, and the upper surfaces of the plurality of L-shaped plates 7 are fixedly connected to tooth plates 16, and the gears 15 are meshed with the corresponding tooth plates 16 (such as Figure 7 As shown), the side wall of the shaped plate 27 is fixedly connected with a motor 26 (as shown Figure 6 As shown), the movable end of the motor 26 is fixedly connected to one end of the cross bar 14.

[0034] The infusion mechanism also includes a second tube 12 fixedly connected to the top of the first annular groove 9, the inner wall of the liquid inlet tube 3 is fixedly connected to multiple first tubes 11 connected to the outer wall of the ring 10, and the upper end of the second tube 12 is fixedly connected to an infusion tube 13. It should be noted that the infusion tube 13 is connected to an external infusion pump, and nutrient solution can be pumped into the infusion tube 13.

[0035] When it is necessary to water the nutrient solution for the dendrobium seedlings in the multiple cultivation boxes 2, the external infusion pump is started, and then the external nutrient solution passes through the infusion tube 13, the multiple second tubes 12, the multiple first annular grooves 9, the multiple first tubes 11 and the multiple liquid inlet tubes 3 and then flows out through the multiple liquid outlet holes 5, and the nutrient solution is watered for the dendrobium seedlings in the multiple cultivation boxes 2. In this way, the nutrient solution is transported from bottom to top in the matrix, so that the nutrient solution can be fully penetrated into the matrix, avoiding the prior art of spraying the nutrient solution above the dendrobium, which easily causes the nutrient solution to accumulate on the upper surface of the matrix and is not easy to flow down, affecting the effect of watering the nutrient solution;

[0036] At the same time, the driving motor 26 intermittently rotates forward and backward, and the cross bar 14 drives the multiple gears 15 to intermittently rotate forward and backward. At this time, the multiple gears 15 drive the multiple L-shaped plates 7 to intermittently move in the direction away from the cultivation bed 1 and the direction close to the cultivation bed 1 through the multiple tooth plates 16. At this time, the multiple fixing rings 8 drive the multiple liquid inlet pipes 3 to move back and forth in the multiple cultivation boxes 2 through the multiple circular rings 10. At this time, the multiple liquid inlet pipes 3 can loosen the matrix while transporting nutrient solution into the matrix, thereby avoiding consolidation in the matrix, affecting the respiration of the roots of Dendrobium and the absorption of nutrients in the nutrient solution.

[0037] The cultivation bed 1 is provided with a rotating mechanism, which includes a plurality of second annular grooves 31 provided on the side wall of the cultivation bed 1, the plurality of second annular grooves 31 corresponding to the plurality of liquid inlet pipes 3 one by one, and a plurality of arc-shaped plates 32 (such as Figure 3 As shown), the ends of the multiple arc plates 32 away from the second annular groove 31 are fixedly connected to a worm gear 33, and the side wall of the liquid inlet pipe 3 located outside the cultivation bed 1 is fixedly connected to multiple clamping rods 34 (as shown Figure 3As shown), the side walls of the plurality of latch rods 34 are slidably connected to the inner side walls of the worm gear 33, and the side walls of the cross bar 14 are fixedly connected to a plurality of worms 35, which are meshed with the corresponding worm gears 33.

[0038] When the cross bar 14 intermittently rotates forwards and backwards, the worm 35 is driven to rotate, and then the worm 35 drives the worm wheel 33 to rotate. At this time, the worm wheel 33 drives the liquid inlet pipe 3 to rotate through the multiple clamping rods 34. Since the side walls of the multiple clamping rods 34 are slidingly connected to the inner wall of the worm wheel 33, during the process of the liquid inlet pipe 3 driving the multiple clamping rods 34 to move back and forth, the worm wheel 33 can always drive the liquid inlet pipe 3 to rotate through the multiple clamping rods 34. That is, the liquid inlet pipe 3 rotates during the back and forth movement in the cultivation box 2, which can evenly transport the nutrient solution to the substrate. At the same time, the rotating liquid inlet pipe 3 can loosen the soil of the substrate again, thereby increasing the cultivation effect on the Dendrobium seedlings.

[0039] The inlet pipe 3 is provided with a disrupting mechanism, which includes two slide plates 17 slidably connected to the inner wall of the inlet pipe 3. The side walls of the two slide plates 17 that are away from each other are elastically connected to the inner wall of the inlet pipe 3 through a plurality of first springs 18. The side walls of the two slide plates 17 that are away from each other are fixedly connected with a plurality of disrupting rods 19 (such as Figure 5 shown).

[0040] The inner wall of the liquid inlet pipe 3 near the ring 10 is sealed and slidably connected with a rectangular rod 20 (such as Figure 3 The side wall of the rectangular rod 20 located in the liquid inlet pipe 3 is rotatably connected to the side walls of the two slide plates 17 through two rotating rods 21 (as shown in FIG. Figure 5 shown).

[0041] The side wall of the fixed ring 8 away from the cultivation bed 1 is fixedly connected with two slide bars 22, and the side walls of the two slide bars 22 are slidably connected with the vertical plate 23. The side wall of the vertical plate 23 is elastically connected to the side wall of the fixed ring 8 through a plurality of second springs 24. The side wall of the rectangular rod 20 close to the vertical plate 23 is fixedly connected with a cylinder 25, and the side wall of the cylinder 25 is rotatably connected to the side wall of the vertical plate 23 (such as Figure 5 and Figure 8 As shown in the figure, a plurality of electric push rods 28 corresponding to the plurality of vertical plates 23 are fixedly connected to the side wall of the U-shaped plate 27, and a plurality of electric push rods 28 are fixedly connected to the movable ends of the plurality of electric push rods 28 with a pressing plate 29, and the pressing plate 29 is directly opposite to the corresponding vertical plate 23.

[0042] A water flow sensor 30 (such as Figure 3 As shown), the water flow sensor 30 is electrically connected to its corresponding electric push rod 28 through an external control mechanism, and its control method is the existing technology and will not be described in detail here.

[0043] The water flow sensor 30 can sense the flow of the nutrient solution in the second tube 12 corresponding thereto. When the matrix in the culture box 2 corresponding to the water flow sensor 30 is not seriously solidified, the nutrient solution flowing out of the multiple liquid outlets 5 can quickly enter the matrix. At this time, the nutrient solution in the second tube 12 flows normally, and the water flow sensor 30 senses that the flow signal of the nutrient solution per unit time is normal. At this time, the electric push rod 28 is in the initial position (such as Figure 1 shown);

[0044] When the matrix in the cultivation box 2 corresponding to the water flow sensor 30 is seriously solidified, the nutrient solution flowing out of the multiple liquid outlets 5 slowly enters the matrix. At this time, the nutrient solution in the second tube 12 is almost in a stagnant flow. At this time, the water flow sensor 30 senses that the flow signal of the nutrient solution per unit time is abnormal. At this time, the electric push rod 28 corresponding to the water flow sensor 30 is controlled to extend through the external control mechanism, so that the pressure plate 29 moves to a position close to the vertical plate 23. Then, in the subsequent process of the L-shaped plate 7 driving the fixing ring 8 to move back and forth, the vertical plate 23 slides back and forth under the squeezing of the pressure plate 29 and the action of the multiple second springs 24. At this time, the vertical plate 23 drives the rectangular rod 20 through the cylinder 25. The inner wall of the liquid inlet pipe 3 moves back and forth, and at this time the rectangular rod 20 drives the two slides 17 to intermittently approach and move away from each other through the two rotating rods 21, driving multiple disrupting rods 19 to intermittently extend from multiple liquid outlet holes 5, so that during the rotation of the liquid inlet pipe 3, the multiple disrupting rods 19 are driven to rotate, and the severely consolidated matrix in the cultivation box 2 is disturbed and loosened, thereby further increasing the cultivation effect on the Dendrobium seedlings. In this way, corresponding treatment can be carried out according to the consolidation conditions of the matrix in different cultivation boxes 2, avoiding the situation that when the matrix in the cultivation box 2 is not severely consolidated, the treatment at this time affects the burying effect of the Dendrobium seedlings, and the intermittent extension of the disrupting rods 19 from the multiple liquid outlet holes 5 will not affect the normal outflow of the nutrient solution.

[0045] When pouring nutrient solution on the dendrobium in the cultivation box 2, the external infusion pump is started, and then the external nutrient solution flows out through the infusion tube 13, the plurality of second tubes 12, the plurality of first annular grooves 9, the plurality of first tubes 11 and the plurality of liquid inlet tubes 3 through the plurality of liquid outlet holes 5, and the nutrient solution is poured on the plurality of dendrobium seedlings in the cultivation box 2. In this way, the nutrient solution is transported from bottom to top in the matrix, so that the nutrient solution can fully penetrate into the matrix;

[0046] At the same time, the driving motor 26 intermittently rotates forward and backward, and the cross bar 14 drives the multiple gears 15 to rotate forward and backward intermittently. At this time, the multiple gears 15 drive the multiple L-shaped plates 7 to intermittently move in the direction away from the cultivation bed 1 and the direction close to the cultivation bed 1 through the multiple tooth plates 16. At this time, the multiple fixing rings 8 drive the multiple liquid inlet pipes 3 to move back and forth in the multiple cultivation boxes 2 through the multiple rings 10. At this time, the multiple liquid inlet pipes 3 can loosen the matrix while transporting the nutrient solution into the matrix, so as to avoid consolidation in the matrix, which affects the respiration of the roots of Dendrobium and the absorption of nutrients in the nutrient solution;

[0047] The worm 35 is driven to rotate when the cross bar 14 intermittently rotates forward and backward, and then the worm 35 drives the worm wheel 33 to rotate. At this time, the worm wheel 33 drives the liquid inlet pipe 3 to rotate through the multiple clamping rods 34. Since the side walls of the multiple clamping rods 34 are slidably connected to the inner side wall of the worm wheel 33, when the liquid inlet pipe 3 drives the multiple clamping rods 34 to move back and forth, the worm wheel 33 can always drive the liquid inlet pipe 3 to rotate through the multiple clamping rods 34. That is, the liquid inlet pipe 3 is accompanied by rotation during the back and forth movement in the cultivation box 2, which can evenly transport the nutrient solution into the matrix. At the same time, the rotating liquid inlet pipe 3 can loosen the soil of the matrix again, thereby increasing the cultivation effect on the Dendrobium seedlings.

[0048] When the matrix in the cultivation box 2 corresponding to the water flow sensor 30 is not seriously solidified, the nutrient solution flowing out of the multiple liquid outlets 5 can quickly enter the matrix. At this time, the nutrient solution in the second tube 12 flows normally, and the water flow sensor 30 senses that the flow signal of the nutrient solution per unit time is normal. At this time, the electric push rod 28 is in the initial position (such as Figure 1 shown);

[0049] When the matrix in the cultivation box 2 corresponding to the water flow sensor 30 is seriously solidified, the nutrient solution flowing out of the multiple liquid outlets 5 slowly enters the matrix. At this time, the nutrient solution in the second tube 12 is almost in a stagnant flow. At this time, the water flow sensor 30 senses that the flow signal of the nutrient solution per unit time is abnormal. At this time, the electric push rod 28 corresponding to the water flow sensor 30 is controlled to extend through the external control mechanism, so that the pressure plate 29 moves to a position close to the vertical plate 23. Then, in the subsequent process of the L-shaped plate 7 driving the fixing ring 8 to move back and forth, the vertical plate 23 slides back and forth under the squeezing of the pressure plate 29 and the action of the multiple second springs 24. At this time, the vertical plate 23 is driven by the cylinder 25 to The movable rectangular rod 20 moves back and forth on the inner wall of the liquid inlet pipe 3. At this time, the rectangular rod 20 drives the two slides 17 to intermittently approach and move away from each other through the two rotating rods 21, and drives multiple disrupting rods 19 to intermittently extend from the multiple liquid outlet holes 5, so that during the rotation of the liquid inlet pipe 3, the multiple disrupting rods 19 are driven to rotate, and the seriously consolidated matrix in the cultivation box 2 is disturbed and loosened. In this way, the corresponding treatment can be carried out according to the consolidation conditions of the matrix in different cultivation boxes 2, avoiding the situation that when the matrix in the cultivation box 2 is not seriously consolidated, the treatment at this time affects the burying effect of the Dendrobium seedlings, and the intermittent extension of the disrupting rods 19 from the multiple liquid outlet holes 5 will not affect the normal outflow of the nutrient solution.

[0050] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
