[0045] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0046] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] like Figure 1-Figure 22 As shown, a seedling raising device for soilless cultivation according to an embodiment of the present application includes a water storage mechanism 1, a supporting mechanism 2, a plurality of seedling raising chambers 3 and a water replenishing mechanism 4.

[0048] The water storage mechanism 1 stores nutrient solution.

[0049] The supporting mechanism 2 includes a gantry 21 symmetrically fixed to the water storage mechanism 1, and two symmetrically arranged gantries 21 are rotatably connected to rocker arms 22 respectively, and a positioning rod 23 is rotatably connected between the two rocker arms 22. The positioning rod 23 is slidably connected to the water storage mechanism 1 through a power device.

[0050] It is understandable that when the positioning rod 23 is driven to move on the water storage mechanism 1 by the power device, the swing arm 22 can be driven to rotate at a certain angle with the rotation point between the swing arm 22 and the gantry 21 as the axis.

[0051] Multiple seedling cabins 3 are evenly mounted on two rocker arms 22, and the seedling cabins 3 are rotatably connected to the rocker arms 22. The drainage end of the seedling cabin 3 is connected to the water storage mechanism 1. It can be understood that when the angle of the rocker arm 22 changes, the seedling cabin 3 can still remain stable and its own angle will not change, so as to ensure that the crops therein will not fall.

[0052] The water replenishment mechanism 4 includes a water pump 41, the water inlet end of the water pump 41 is connected to the water storage mechanism 1, and the water outlet end of the water pump 41 is respectively connected to multiple seedling chambers 3. Therefore, it can be understood that the nutrient solution in the water storage mechanism 1 can be transported to multiple seedling chambers 3 by using the water pump 41, and then flows back to the inside of the water storage mechanism 1 after passing through the seedling chambers 3, so that the nutrient solution forms a circulation, improves the utilization rate of the nutrient solution and makes the nutrient solution flow, avoids the precipitation of the nutrient solution or the insufficient nutrients at the root system of the green plants due to the stagnation of the nutrient solution, and affects the normal growth of the green plants.

[0053] It should be noted that flow valves are provided at the places where the multiple seedling chambers 3 are connected to the water outlet ends of the water pump 41 respectively. The flow valve is a prior art and it only serves to control the amount of liquid supplied by the water pump 41 to the multiple seedling chambers 3 so that the flow rate of nutrient solution in the multiple seedling chambers 3 can be as similar as possible.

[0054] In addition, a soilless seedling raising device according to an embodiment of the present application also has the following additional technical features:

[0055] In a specific embodiment of the present application, the water storage mechanism 1 includes: a water storage tank 11, a water outlet tank 12, a water return tank 13, a water tank flange 113 and a shielding cover 14.

[0056] Specifically, the two ends of the water tank 11 are connected with a pumping cabin 111 and a drainage cabin 112. The side of the pumping cabin 111 facing the inside of the water tank 11 is connected with a pumping pipe 114, and the side of the drainage cabin 112 facing the outside of the water tank 11 is connected with a drainage pipe 115. The side of the drainage cabin 112 facing the inside of the water tank 11 is connected to the water tank 11. It can be understood that the nutrient solution in the entire water tank 11 can be circulated under the action of the water pump 41 to avoid the formation of dead water areas in the water tank 11. At the same time, the existence of the drainage pipe 115 facilitates the discharge and emptying of the liquid in the water tank 11 and the replacement of the nutrient solution in the water tank 11.

[0057] The water outlet tank 12 is fixedly connected to the upper end of the pumping compartment 111, and a through first chute 121 is provided on the side wall and the upper end surface of the water outlet tank 12, and the cross section of the first chute 121 is L-shaped; the return water tank 13 is fixedly connected to the upper end of the drainage compartment 112, and a through second chute 131 is provided on the side wall and the upper end surface of the return water tank 13, and the cross section of the second chute 131 is L-shaped; the second chute 131 and the first chute 121 are respectively located at the same end of the return water tank 13 and the water outlet tank 12. It should be noted that the length and specific position of the first chute 121 and the second chute 131 determine the swing amplitude of the swing arm 22.

[0058] The pool flange 113 is fixedly connected to the inner wall of the water storage tank 11, and the shielding cover 14 covers the water storage tank 11 between the pumping compartment 111 and the drainage compartment 112. Specifically, it covers the pool flange 113 to cover the water storage tank 11, thereby preventing mosquitoes from breeding in the nutrient solution therein and reducing water evaporation.

[0059] Furthermore, the shielding cover 14 includes an integral connecting end 141 and a supporting end 142 evenly fixed to the connecting end 141. The connecting end 141 is flexibly configured and the supporting end 142 is rigidly configured. It can be understood that this design allows the shielding cover 14 to be removed in a rolled-up manner, thereby saving the space occupied by the shielding cover 14 when storing.

[0060] Among them, in the specific embodiment of the present application, the rocker arm 22 includes: a positioning section 221, a swing section 222, an extension section 223 and a sliding shaft 224. The positioning section 221 is rotatably connected to the gantry 21, the swing section 222 is rotatably connected to the positioning rod 23, the swing section 222 is respectively slidably matched with the first slide groove 121 and the second slide groove 131 (in the specific embodiment of the present application, there are two rocker arms 22), and the two ends of the extension section 223 are respectively limited and slidably inserted into the positioning section 221 and the swing section 222. In this way, it can be understood that when the angle of the rocker arm 22 changes, the length between the swing section 222 and the positioning section 221 can be changed through the extension section 223. Therefore, when the angle of the rocker arm 22 changes, the positioning rod 23 will undergo a corresponding displacement along the length direction of the first slide groove 121 and the second slide groove 131.

[0061] Specifically, the sliding shaft 224 is rotatably inserted into the swing section 222 and fixedly connected to the end of the positioning rod 23. The sliding shaft 224 slides with the first slide groove 121 and the second slide groove 131 respectively, thereby realizing the rotational connection between the swing section 222 and the positioning rod 23.

[0062] In a specific embodiment of the present application, a first fixing ring 231 and a second positioning ring 232 are fixedly connected to the positioning rod 23 , respectively. A nut is fixedly connected to the first fixing ring 231 , and a sliding sleeve is fixedly connected to the second positioning ring 232 .

[0063] Furthermore, the power device is a driving component 24, which includes: a screw 241, two active end fixing blocks 242, a sliding rod 243 and two passive end fixing blocks 244, the screw 241 is threadedly matched with the nut on the first fixing ring 231; the two active end fixing blocks 242 are symmetrically fixed to the water tank 11, and the screw 241 is connected with two rotations; the sliding rod 243 and the screw 241 are arranged in parallel, and are slidingly matched with the sleeve on the second positioning ring 232; the two passive end fixing blocks 244 are symmetrically fixed to the water tank 11, and are away from the two active end fixing blocks 242, and the sliding rod 243 is fixed to the two passive end fixing blocks 244.

[0064] It is understandable that by rotating the screw rod 241 , the first fixing ring 231 can be driven to move along the axial direction of the screw rod 241 , and the sliding rod 243 will assist in stabilizing the displacement of the positioning rod 23 to prevent it from deflecting during the displacement process.

[0065] Furthermore, two locking members 31 are fixedly connected to both ends of the seedling raising cabin 3 , respectively. The two locking members 31 are fixedly sleeved on the swing rod 22 , respectively. A seedling raising tray 33 is embedded in the seedling raising cabin 3 .

[0066] It should be noted that in the specific embodiment of the present application, the locking piece 31 is preferably a clamp to facilitate adjustment of the position of the corresponding seedling chamber 3 on the rocker arm 22. At the same time, an axle rod is fixed to the clamp, and the seedling chamber 3 and the axle rod are rotationally connected, and the connection point is located on the center line of the seedling chamber 3. That is, after the rotational connection is formed between the seedling chamber 3 and the locking piece 31, under the action of its own weight, the seedling chamber 3 can maintain a stable state with its bottom facing downward and the top opening facing upward.

[0067] Furthermore, the water pump 41 is respectively connected to a water inlet pipe 411 and a water outlet pipe 412, the water inlet pipe 411 is connected to the water pumping pipe 114, the end of the water outlet pipe 412 is connected to a water transfer tank 42, the water transfer tank 42 is fixed to the gantry 21, and the water transfer tank 42 is rotatably connected to a water transfer pipe 421. It can be understood that the water transfer pipe 421 and the water transfer tank 42 can be rotatably connected by a rotating joint or the like. The technology of rotatable connection is a very mature existing technology and will not be elaborated here.

[0068] The end of the water transfer pipe 421 (the end away from the water transfer box 42) is connected in series with multiple diversion boxes 43, and the multiple diversion boxes 43 are connected to the multiple seedling chambers 3 in a one-to-one correspondence; the diversion boxes 43 are respectively connected to the diversion pipes 431 and the guide pipes 432; the diversion pipe 431 is connected to the seedling chamber 3, and is connected to a flow valve; the guide pipe 432 is connected to two adjacent diversion boxes 43.

[0069] It should be noted that the diverter box 43 and the locking piece 31 on the corresponding seedling chamber 3 are rotationally connected so that the diverter box 43 and the seedling chamber 3 are in a relatively fixed state, that is, when the rocker arm 22 rotates, the seedling chamber 3 and the diverter box 43 maintain the same state.

[0070] It should be further explained that the guide tube 432 is preferably a corrugated hose so as to be applicable to the seedling raising chambers 3 at different positions on the swing arm 22 to prevent the guide tube 432 from being unable to be applied when the distance between adjacent seedling raising chambers 3 changes.

[0071] It can be understood that by setting the flow valve, the flow rate of the nutrient solution supplied by the water transfer tank 42 to each seedling chamber 3 can be controlled so that the flow rate of the nutrient solution in multiple seedling chambers 3 is the same, avoiding large changes in the nutrients absorbed by crops in different seedling chambers 3.

[0072] The following describes the use process of a soilless cultivation seedling raising device according to an embodiment of the present application with reference to the accompanying drawings:

[0073] In daily use, the entire seedling raising device is placed on the balcony so that the crops thereon can obtain better lighting. The nutrient solution is poured into the water tank 11, and the shielding cover 14 is laid to prevent mosquitoes from breeding in the water tank 11 and affecting the family living environment. According to the height of the floor of the home and the location where it is placed, the screw 241 is rotated to drive the positioning rod 23 to move along the first slide groove 121 and the second slide groove 131, thereby driving the swing rod 22 rotatably connected at both ends to change its angle. In this way, the multiple seedling raising chambers 3 detachably fixedly mounted on the swing rod 22 will move along with the swing of the swing rod 22, and gradually change from the initial state where the multiple seedling raising chambers 3 are vertically overlapped to the stepped state. It is ladder-shaped, and it can be understood that the displacement amplitude of the seedling cabin 3 is gradually reduced from the bottom to the upper end. In this way, the lighting effect of the crops in each layer of the seedling cabin 3 will be enhanced. During daily cultivation, keep the water pump 41 started, which can pump the nutrient solution in the water storage tank 11 into the transfer tank 42, and transport the nutrient solution to each seedling cabin 3 according to the amount through the series-connected diversion box 43, and return the nutrient solution to the water storage tank 11 through the drainage end of each seedling cabin 3, so that the nutrient solution forms a circulation flow in the entire seedling raising device, which can enhance the actual use efficiency of the nutrient solution. At the same time, the flowing nutrient solution can avoid the dead water area in the seedling cabin 3, which causes the local crops to be unable to absorb enough nutrients.

[0074] In the related art, the height of the seedling raising device for soilless cultivation changes as the crop seedlings grow, and the stepped shape of the seedling raising chamber 3 needs to be further expanded, that is, the horizontal spacing between adjacent seedling raising chambers 3 is expanded to ensure the lighting of the crop seedlings thereon. There is nutrient solution inside the seedling raising chamber 3. If shaking occurs when the horizontal spacing between the seedling raising chambers 3 is changed, the nutrient solution inside may easily spill, causing an impact on the home environment.

[0075] According to some embodiments of the present application, one end of the seedling chamber 3 is fixedly connected to the drainage chamber 32, and an upper positioning rod 321 and a lower positioning tube 322 are respectively fixed to the drainage chamber 32. The upper positioning rod 321 is connected to the gantry 21 in a limited sliding connection, and the lower positioning tube 322 is connected to the drainage chamber 32 and is connected to the return water tank 13 in a limited sliding connection.

[0076] Among them, the drainage chambers 32 on the multiple seedling chambers 3 are staggered, and the upper positioning rod 321 is fixedly connected to the upper end of the drainage chamber 32, and the lower positioning tube 322 is fixedly connected to the lower end of the drainage chamber 32. The multiple seedling chambers 3 are staggered and arranged, which can avoid motion interference between adjacent upper positioning rods 321 and adjacent lower positioning tubes 322 due to the rotation of the rocker arm 22.

[0077] It should be noted that the end surfaces of the plurality of upper positioning rods 321 away from the drainage chamber 32 are flush with each other; the end surfaces of the plurality of lower positioning tubes 322 away from the drainage chamber 32 are flush with each other.

[0078] It should be further explained that, preferably, the length settings of the upper positioning rod 321 and the lower positioning tube 322 are sufficient to ensure that when the corresponding seedling chamber 3 swings following the swing arm 22, the upper positioning rod 321 and the lower positioning tube 322 can still maintain a limited sliding connection with their respective corresponding gantry 21 and return water tank 13.

[0079] Specifically, a lower slide groove 132 is provided on the inner wall of the return water tank 13, and the lower slide groove 132 is provided in at least two rows side by side; an upper slide groove 211 is provided on the side wall of the gantry 21, and the upper slide groove 211 is provided in at least two rows side by side.

[0080] Furthermore, guide sleeves 323 are slidably sleeved on the upper positioning rod 321 and the lower positioning tube 322, and a positioning bolt 324 is fixedly connected to the guide sleeve 323;

[0081] The positioning bolt 324 on the upper positioning rod 321 is slidably fitted in the upper slide groove 211 ; the positioning bolt 324 on the lower positioning tube 322 is slidably fitted in the lower slide groove 132 .

[0082] Thus, it can be understood that the lower slide groove 132 and the upper slide groove 211 arranged side by side and in at least two rows can ensure that the angle of the guide sleeve 323 does not change when the positioning bolt 324 moves therein.

[0083] Therefore, when it is necessary to adjust the horizontal position between adjacent seedling raising chambers 3 during specific use, the screw rod 241 can be directly rotated. When the seedling raising chamber 3 swings following the swing arm 22, the drainage chamber 32 is fixedly connected thereto, and the top and bottom sides of both ends of the drainage chamber 32 are respectively fixedly connected with an upper positioning rod 321 and a lower positioning tube 322. The upper positioning rod 321 and the lower positioning tube 322 are respectively connected to the gantry 21 and the return water tank 13 through their corresponding guide sleeves 323 to maintain a limited sliding connection, and the positioning bolt 324 and the double-row lower slide groove 132 and the upper slide groove 211 can maintain the guide sleeve 32 The angle of 3 will not change, thereby ensuring that the angle of the upper positioning rod 321 and the lower positioning tube 322 will not change. In this way, it can be understood that when the seedling cabin 3 swings following the swing arm 22, its own angle will be kept unchanged through the positioning effect of the upper positioning rod 321 and the lower positioning tube 322. Subsequently, during the process of the seedling cabin 3 swinging following the swing arm 22, it can be ensured to a certain extent that the nutrient solution therein will not spill from the seedling cabin 3, thereby reducing its shaking amplitude. The threaded connection between the screw 241 and the nut on the first fixing ring 231 further ensures the stability of the swing arm 22 during the swinging process.

[0084] In the related art, in this seedling raising device for soilless cultivation, the nutrient solution circulates between the water storage tank 11 and the seedling raising chamber 3 under the action of the water pump 41, and the length, width, height of the seedling raising chamber 3, as well as the relevant parameters such as the growth of the crop root system, will more or less lead to the existence of a certain degree of dead water area when the nutrient solution circulates in the seedling raising chamber 3, resulting in incomplete circulation of the nutrient solution in the seedling raising chamber 3, affecting the normal growth of the crops thereon.

[0085] According to some embodiments of the present application, a plurality of flow equalizing plates 34 are embedded in the seedling raising chamber 3, and the plurality of flow equalizing plates 34 are evenly arranged.

[0086] The upper end surface of the flow equalizing plate 34 abuts against the seedling tray 33, which supports the seedling tray 33 and plays a certain role in intercepting and draining the circulating nutrient solution.

[0087] Specifically, a plurality of flow balancing channels 341 are disposed on the lower end surface of the flow balancing plate 34 , and the plurality of flow balancing channels 341 are evenly disposed.

[0088] It should be noted that the setting of the flow equalization channel 341 must meet the flow rate of the nutrient solution to avoid overflow of the nutrient solution from the seedling chamber 3.

[0089] Therefore, during specific use, when the nutrient solution circulates in the seedling chamber 3, it can be understood that the nutrient solution will be blocked by the evenly arranged flow equalizing plates 34 one by one, and the nutrient solution can and can only pass through the flow equalizing plate 34 from the flow equalizing channel 341 at the bottom of the flow equalizing plate 34. In this way, the nutrient solution in the seedling chamber 3 will flow from the inner bottom of the seedling chamber 3 when it circulates, and will be diverted and drained through multiple flow equalizing channels 341. Therefore, the nutrient solution will be forced to fully contact with the inner bottom of the seedling chamber 3 during the circulation process, thereby reducing the formation of dead water areas and improving the crops' full absorption of nutrients in the nutrient solution.

[0090] It should be noted that the specific model specifications of the screw 241, the seedling tray 33 and the water pump 41 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0091] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
