Description

Technical Field

[0001] The present invention relates to the technical field of forage monitoring, and particularly to a root development monitoring device for forage growth. Background Art

[0002] Hydroponics is a new type of soilless cultivation method for plants. Its core is to directly immerse the roots of plants in a liquid, and the liquid can replace the soil to provide growth factors such as water, nutrients, and oxygen to the plants, enabling the plants to grow normally. Existing soilless hydroponics is carried out in an artificial indoor environment with suitable temperature, humidity, and light. The suitable environment greatly promotes the rapid, stable, and high-yield growth of hydroponic grass.

[0003] Patent Publication No. CN216452474U discloses a fresh forage remote monitoring device, specifically related to the technical field of fresh forage monitoring. It includes a bottom plate and a hydroponic box frame. A number of cultivation holes are equidistantly arranged on the cultivation tray. Motor fixing plates are fixedly installed on both the left and right sides of the hydroponic box frame. A driving motor is fixedly installed on the upper surface of the motor fixing plate through bolts. The output ends of the driving motors are fixedly connected with gears. Rack bars are fixedly installed on both the left and right sides of the cultivation tray. It can adjust the growth height of the forage, avoid the roots of the forage being completely immersed in water and causing root rot. By setting a temperature and humidity sensor and a controller, the controller sends the received data to the mobile APP of the staff or the software on the computer through the cloud server, and the staff can observe the growth situation of the forage in real time and can also adjust the growth environment of the forage on the software.

[0004] However, considering the above technical solution and the existing mature technical solutions, there are two artificial cultivation methods for forage, namely hydroponics and soil cultivation. However, since the fresh forage grows in the cultivation box, it is inconvenient for the staff to monitor and view the growth of the roots of the forage. Even when viewing, they can only move the forage to observe, which is likely to damage the forage in that area.

[0005] Therefore, it is necessary to provide a root development monitoring device for forage growth to solve the above technical problems. Summary of the Invention

[0046] The realization, functional features and advantages of the object of the present invention will be further described in conjunction with the embodiments with reference to the accompanying drawings. Detailed implementation manners

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0048] The present invention provides a root development monitoring device for forage growth.

[0049] First Embodiment:

[0050] Please refer to Figures 1 to 12 , a root development monitoring device for forage growth, comprising a planting rack 1, a placement plate 2, a cultivation component 4 and an inspection mechanism 5;

[0051] A hydroponic box 3 is erected above the placement plate 2. The cultivation component 4 includes a partition plate 41 fixedly arranged at the middle position of the hydroponic box 3. Inner lining plates 44 are fixedly arranged on both sides of the inner wall of the hydroponic box 3 and located on both sides of the partition plate 41, and the number of the inner lining plates 44 is four. Hydroponic trays 42 are placed on the upper surfaces of the four inner lining plates 44. A transparent observation frame 43 is fixedly arranged horizontally at the middle position inside the hydroponic box 3;

[0052] Please refer to Figure 3 and Figure 4 : When cultivating forage, the user can take out the hydroponic trays 42 in sequence, inject all the prepared hydroponic nutrient solution into the hydroponic box 3, and then insert the fresh forage to be cultivated onto the hydroponic trays 42, and place the hydroponic trays 42 on the inner lining plates 44 in sequence, so that the roots of the fresh forage are in the hydroponic nutrient solution, and the hydroponic work of forage can be realized;

[0053] Compared with the traditional hydroponic design, soil cultivation work can also be carried out in this case. When soil cultivation is needed, the user can remove the hydroponic trays 42, because soil cultivation does not require the use of hydroponic trays 42, and then add the prepared forage soil to the hydroponic box 3, and fresh forage can be directly planted in the hydroponic box 3.

[0054] Both sides of the hydroponic box 3 are installed with positioning plates 9 through bolts. The inspection mechanism 5 includes a rack frame 51 slidably connected inside the two positioning plates 9. An electric gear vehicle 52 is installed inside the rack frame 51. A sliding sleeve 53 is installed on the outer wall of the electric gear vehicle 52. A key rod 54 is slidably connected inside the sliding sleeve 53. A lifting seat 55 is installed at the bottom end of the key rod 54. A storage battery 56 is installed inside the lifting seat 55. A two-way camera 57 is installed on the side of the lifting seat 55 and on one side of the storage battery 56. A limiting shaft 513 is fixedly installed on the outer wall of the lifting seat 55 and outside the storage battery 56. A first pulley 58 is rotatably connected to the outer wall of the limiting shaft 513. A second pulley 59 is rotatably connected to the axis of the limiting shaft 513 through a bearing. A return spring 510 is installed inside the sliding sleeve 53 and above the key rod 54. A limiting plate 511 is installed at the bottom of the rack frame 51 and inside the transparent observation frame 43. Inclined surfaces 512 are provided on both the left and right sides of the limiting plate 511.

[0055] Please refer to Figure 5 and Figure 6 During the growth cycle of the forage grass, it is necessary to monitor the root growth of the forage grass. When viewing, the user can start the electric gear vehicle 52 to freely perform horizontal displacement along the horizontal direction of the rack frame 51;

[0056] In the initial state, the return spring 510 is in a contracted state, and the two-way camera 57 is located at the topmost position and on the right side of the transparent observation frame 43.

[0057] Please refer to Figure 7 and Figure 10 : When the user starts the electric gear vehicle 52 and moves it to the left, the first pulley 58 will move to the right accordingly. During the movement, the first pulley 58 will fit on the inclined surface 512 on the right side of the limiting plate 511. And as the electric gear vehicle 52 continues to move, the first pulley 58 will be subjected to a horizontal force and will move along the inclined surface 512 and adapt to the inclined surface 512, thereby pulling the lifting seat 55 to slide downward along the vertical direction of the sliding sleeve 53 through the key rod 54. And during the downward sliding of the key rod 54, the return spring 510 will be stretched, so that the two-way camera 57 can also extend downward into the transparent observation frame 43 during the movement.

[0058] Please refer to Figure 7 and Figure 11 : As the electric gear vehicle 52 continues to move to the left, the first pulley 58 slides onto the bottommost plane of the limiting plate 511. In this way, the continuous movement of the electric gear vehicle 52 can control the two-way camera 57 to continuously move to the left along the horizontal direction, and perform video visual monitoring on the front and back directions of the transparent observation frame 43 during the movement;

[0059] When it moves to the leftmost side, it will follow the inclined surface 512 on the left side to return to the initial state.

[0060] An auxiliary mechanism 6 is installed inside the transparent observation frame 43 and below the limit plate 511. The auxiliary mechanism 6 includes a lifting plate 63. A first mounting seat 61 is fixedly provided at the inner bottom of the transparent observation frame 43. A connecting plate 62 is rotatably installed inside the first mounting seat 61 through a torsion spring. A second mounting seat 66 is rotatably installed on the upper end of the connecting plate 62 through a torsion spring. A limit block 65 is fixedly provided on the top of the second mounting seat 66. A limit slot 64 is provided inside the lifting plate 63.

[0061] The limit block 65 and the limit groove 64 are slidably connected, the front and rear positions of the lifting plate 63 fit the inside of the transparent observation frame 43, and the outer wall of the lifting plate 63 and the back inner wall of the transparent observation frame 43 are vertically limited and slidably connected.

[0062] See also Figure 11 : When the first pulley 58 moves to the plane at the lowest position of the limit plate 511, the first pulley 58 can continue to fit on the limit plate 511, but the wheel diameter of the second pulley 59 is larger than the wheel diameter of the first pulley 58. At this time, the surface of the second pulley 59 will be subjected to downward force to control the lifting plate 63 to move downward.

[0063] See also Figure 8 , Figure 9 and Figure 11 When the lifting plate 63 moves downward, it will control the second mounting seat 66 to control the connecting plate 62 to perform a circular flipping motion along the axis of the first mounting seat 61, and the connecting plate 62 will shrink when the lifting plate 63 descends. At the same time, when the lifting plate 63 descends, the second mounting seat 66 slides in the limiting groove 64 through the limiting block 65, so that the interference effect can be eliminated, and the lifting plate 63 can be ensured to complete the up and down lifting motion smoothly.

[0064] Preferably, from Figure 8 It can be seen that the front and rear outer walls of the lifting plate 63 can be made of rubber and designed in an arc shape, which can ensure that the lifting plate 63 can slide more smoothly on the inner wall of the transparent observation frame 43.

[0065] Combination Figure 7 and Figure 12It can be seen that the second pulley 59 is arranged outside the first pulley 58. Therefore, the second pulley 59 does not contact the limiting plate 511. Therefore, only the first pulley 58 can move under the limiting plate 511, and the second pulley 59 only serves to support the lifting plate 63. And during the rolling movement of the first pulley 58, the second pulley 59 rolls on the lifting plate 63 while applying force to the lifting plate 63. This can ensure that the rotational movements between the first pulley 58 and the second pulley 59 do not interfere with each other. Secondly, it can also eliminate the frictional force between the lifting plate 63 and the second pulley 59.

[0066] Secondly, the outer wall of the lifting plate 63 is also in limiting sliding connection with the transparent observation frame 43, which can ensure that the lifting plate 63 realizes the up-and-down lifting movement at a fixed position and prevent the lifting plate 63 and the limiting block 65 from derailing.

[0067] The storage battery 56 is electrically connected to the bidirectional camera 57, and both the upper and lower ends of the return spring 510 are fixedly connected to the inner top of the sliding sleeve 53 and the top of the key rod 54.

[0068] The diameter of the second pulley 59 is larger than that of the first pulley 58, and the shapes of the four inner lining plates 44 are all in a "U" shape structure.

[0069] Please refer to Figure 12 : It can be understood that since the width of the first pulley 58 is the same as the thickness of the limiting plate 511, this can only ensure that the first pulley 58 moves along the track on the limiting plate 511, and the second pulley 59 does not contact the limiting plate 511 during the movement. Secondly, the bidirectional camera 57 adopts an embedded design for the end towards the second pulley 59, which can ensure that the bidirectional camera 57 can monitor both sides and at the same time avoid interference during the sliding of the first pulley 58.

[0070] In this embodiment: Compared with the traditional design, in this case, a transparent observation frame 43 is arranged at the middle position of the hydroponic tank 3, and a bidirectional camera 57 that can adaptively lift and lower according to the shape of the two inclined surfaces 512 on both sides of the limiting plate 511 is arranged to observe the transparent observation frame 43. Through the transparent observation frame 43, the development of the forage grass roots in the hydroponic tank 3 can be directly seen (various situations such as the shapes of the main roots and lateral roots, the growth of lateral roots on the main roots, the growth degree of the main roots, and whether the roots are spoiled). Secondly, the transparent observation frame 43 is installed in a penetrating manner at the middle position of the hydroponic tank 3, and users can directly see the development status of the forage grass roots. Secondly, the forage grass at the middle position can better reflect the growth of the overall forage grass, which also improves the accuracy of monitoring. And during the movement, it can be linked to lift, achieving a through-type and non-blind-spot monitoring view, and at the same time facilitating users to operate and replace the bidirectional camera 57 or the storage battery 56;

[0071] Secondly, the two-way camera 57 can control the lifting plate 63 to move downward against the inner wall of the transparent observation frame 43 during the descent process. Since the entire hydroponic environment is carried out in a greenhouse, but the entire transparent observation frame 43 is embedded in the hydroponic box 3, one side of the transparent observation frame 43 is in continuous contact with the hydroponic environment, so that a temperature difference will be formed between the inside and outside of the transparent observation frame 43, which may easily cause water vapor and mist to appear inside. In this way, the downward movement of the lifting plate 63 can effectively remove the mirror water mist in the transparent observation frame 43 and can also remove dust, thereby ensuring that the image acquisition by the two-way camera 57 is clearer and more accurate.

[0072] Second embodiment:

[0073] See also Figures 13 to 15 , further comprising a water quality collection mechanism 7, a connecting pipe 10 is installed on both the left and right sides of the hydroponic box 3, and a water supply pipe 11 is integrally provided on the outer wall of the connecting pipe 10;

[0074] The water quality collection mechanism 7 comprises a fixed plate 71 fixed on the upper surface of the placing plate 2, a sliding frame 72 is slidably connected to the upper surface of the fixed plate 71, a collection tube 74 is installed above the sliding frame 72, a knob 73 is threadedly connected inside the sliding frame 72 and on both sides of the collection tube 74, a first one-way valve 75 is installed at the axis of the collection tube 74, a second one-way valve 76 is installed on the outer wall of the collection tube 74 and on one side of the first one-way valve 75, a piston 77 is slidably connected to the inner wall of the collection tube 74, an air bag 78 is installed on the upper surface of the fixed plate 71 and in the same horizontal direction as the piston 77, a hose 79 is installed on the outer wall of the air bag 78, a contact tube 710 is integrated at the inlet end of the first one-way valve 75, and an annular folding bag 711 is embedded in the contact tube 710;

[0075] A water intake pipe 12 is fixedly arranged on the outer wall of the hydroponic box 3 and in the same horizontal direction as the collecting tube 74. A detachable pipe 13 is installed on the outer end flange of the water intake pipe 12. Water absorbent cotton 14 is arranged inside the detachable pipe 13. A sealing plate 15 is installed on the threaded seal of the outer end of the detachable pipe 13.

[0076] The first one-way valve 75 allows one-way passage from the outside to the inside of the collection tube 74, and the second one-way valve 76 allows one-way passage from the inside of the collection tube 74 to the outside. The outlet ends of the annular folding bag 711 and the hose 79 are sealed.

[0077] See also Figures 13 to 15 : Before collecting water samples, the user can rotate and remove the sealing plate 15 to expose the detachable tube 13, and then slide the sliding frame 72 on the fixed plate 71 in the direction of the detachable tube 13 until the contact cylinder 710 contacts the outermost absorbent cotton 14 in the detachable tube 13;

[0078] Then, the knob 73 is rotated to lock the sliding frame 72 and the fixing plate 71, and then the user pulls the piston plate 77 with force to generate negative pressure suction in the collection tube 74, and the water sample in the absorbent cotton 14 is extracted into the collection tube 74 through the contact tube 710 and the first one-way valve 75. As more water samples are extracted, the amount of water samples in the absorbent cotton 14 decreases accordingly. After that, when the piston 77 is pulled to the position of the air bag 78, the end of the piston 77 squeezes the air bag 78 to expand and inflate the annular folding bag 711 through the hose 79;

[0079] After the extraction is completed, the piston 77 can be moved to squeeze the water sample in the collection tube 74 out through the second one-way valve 76, and a collection bottle can be placed outside the second one-way valve 76.

[0080] It can be understood that: since the bottom of the sliding frame 72 is designed in a dovetail shape, it can ensure that the entire collection tube 74 can slide freely on the fixed plate 71, and secondly, when the knob 73 is rotated, the sliding frame 72 and the fixed plate 71 can be subjected to force to ensure the stability of the sliding frame 72;

[0081] This embodiment: Compared with the traditional water sample collection design, this case adopts an external detachable tube 13 design in the water intake pipe 12, and a layer of superimposed absorbent cotton 14 is arranged inside the detachable tube 13. Whether in a hydroponic environment or a soil culture environment, water samples can be collected and monitored. In the hydroponic environment, the absorbent cotton 14 can prevent the liquid in the hydroponic box 3 from overflowing quickly. If in a soil culture environment, the absorbent cotton 14 can absorb the moisture in the soil culture environment and filter the sediment to ensure that the water sample is purer.

[0082] Secondly, in the process of extracting the piston 77 to collect water samples, the annular folded bag 711 in the contact tube 710 can be controlled to expand. When expanding, the sealing between the absorbent cotton 14 and the contact tube 710 can be enhanced to ensure that the water sample can be extracted quickly and stably.

[0083] Third embodiment:

[0084] See also Figures 13 to 15 , and also includes a water replenishment mechanism 8, which includes a mounting frame 81 installed on the upper surface of the placement plate 2 and located on one side of the fixed plate 71, and a spring pressure plate 83 is slidably connected inside the mounting frame 81, and a water bag 82 is installed inside the mounting frame 81 and in contact with one side of the spring pressure plate 83, and the outlet end of the water bag 82 and the water inlet end of the water replenishment pipe 11 are sealed and installed, and a trigger plate 84 is fixed on the upper surface of the sliding frame 72.

[0085] See also Figure 14: In the second embodiment, after the water sample collection is completed, the sealing plate 15 is used to seal the detachable tube 13. Then, the knob 73 is rotated and loosened, and the sliding frame 72 is slid away from the detachable tube 13 to switch from the water sample collection state to the normal working state. During the switching process, the sliding frame 72 can be continuously moved to control the trigger plate 84 on the side to squeeze the spring pressing plate 83;

[0086] When the spring pressing plate 83 is subjected to an external force, it will move towards the inside of the installation frame 81, and the spring pressing plate 83 can squeeze and compress the control water sac 82. When the water sac 82 is compressed, the liquid inside will be squeezed into the water replenishing pipe 11, and finally it can enter the communicating pipe 10 through the water replenishing pipe 11, and the communicating pipe 10 will quickly replenish water into the hydroponic boxes 3 on both sides.

[0087] In this embodiment: Compared with the traditional design, after the water sample collection work is completed in this case, during the process of switching from the water sample collection work to the normal working mode, the user can control the trigger plate 84 on the side of the sliding frame 72 to squeeze the spring pressing plate 83 to compress the water sac 82. The outer wall of the water sac 82 can be externally provided with a nutrient solution storage box or other liquid storage devices. The water sac 82 can quickly replenish water into the hydroponic box 3 through the water replenishing pipe 11;

[0088] The water sac 82 can be set to the same size as the collection cylinder 74, and the same amount of water sample can be replenished, which can ensure that the hydroponic environment or soil cultivation environment in the hydroponic box 3 has not changed, and it can ensure that the growth of forage grass is not affected after the water sample is collected.

[0089] Please refer to Figures 1 to 15 , the working principle of a root development monitoring device for forage grass growth provided by the present invention is as follows:

[0090] Step S1: Hydroponic method; All the prepared hydroponic nutrient solution is injected into the hydroponic box 3. After that, the fresh forage grass to be cultivated needs to be inserted onto the hydroponic tray 42, and the hydroponic tray 42 is successively placed on the inner lining plate 44 so that the roots of the fresh forage grass are in the hydroponic nutrient solution, and the hydroponic work of the forage grass can be realized;

[0091] Soil cultivation method; Compared with the traditional hydroponic design, this case can also carry out soil cultivation work. If soil cultivation is needed, the user can remove the hydroponic tray 42 because the hydroponic tray 42 is not required for soil cultivation. Then, the prepared forage grass cultivation soil is added into the hydroponic box 3, and the fresh forage grass can be directly planted in the hydroponic box 3;

[0092] Step S2: During the forage growth cycle, it is necessary to monitor the root growth of the forage. When viewing, the user can start the electric gear vehicle 52 to freely perform horizontal displacement along the horizontal direction of the rack frame 51. During the movement, the first pulley 58 will fit on the inclined surface 512 on the right side of the limiting plate 511. And as the electric gear vehicle 52 continues to displace, the first pulley 58 will be subjected to a horizontal force and will move along the inclined surface 512 and adapt to the inclined surface 512, thereby pulling the lifting seat 55 to slide downward along the vertical direction of the sliding sleeve 53 through the key rod 54. And during the downward sliding of the key rod 54, the return spring 510 will be stretched. In this way, it can be controlled that the two-way camera 57 can also extend downward into the transparent observation frame 43 during the movement. As the electric gear vehicle 52 continues to move to the left, the first pulley 58 slides onto the bottom plane of the limiting plate 511. In this way, the continuous movement of the electric gear vehicle 52 can control the two-way camera 57 to continuously move to the left along the horizontal direction. During the movement, video visual monitoring is carried out in the front and back directions of the transparent observation frame 43;

[0093] Step S3: Water sample collection. Rotate and remove the sealing plate 15 to expose the detachable tube 13. Then, it is necessary to slide the sliding frame 72 on the fixed plate 71 in the direction of the detachable tube 13 until the contact cylinder 710 contacts the outermost absorbent cotton 14 in the detachable tube 13. Then rotate the knob 73 to lock the sliding frame 72 and the fixed plate 71. Then the user pulls the piston plate 77 forcefully to generate negative pressure suction in the collection cylinder 74. The water sample in the absorbent cotton 14 will be extracted into the collection cylinder 74 through the contact cylinder 710 through the first one-way valve 75.

[0094] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
