Description

Technical Field

[0001] The utility model belongs to the technical field of hydroponic forage production, and more specifically relates to a hydroponic forage production system. Background Art

[0002] At present, China's high-quality feed has high costs, high dependence on foreign germplasm, and production is limited by land resources, which has hindered the development of high-quality animal husbandry. In particular, some regions have problems such as land resource shortages, few areas suitable for growing forage, and climate restrictions, resulting in a huge gap in high-quality feed that is provided stably throughout the year. This is one of the main challenges for my country to develop high-quality, stable production of animal husbandry throughout the year.

[0003] As a special cultivation method for forage cultivation, hydroponic forage has high water and land resource utilization efficiency, highly controllable environmental conditions, and a harmless production process without the participation of pesticides, herbicides and other chemicals. These advantages make the hydroponic forage system very suitable for harsh climatic environments, such as deserts, areas with poor soil or traditional agricultural areas with high land costs. Especially in semi-arid, arid and drought-prone areas, or some areas suffering from long-term water shortages or non-existent irrigation infrastructure, the production method of hydroponic forage can greatly improve the "difficult" problem of local livestock feed. Through hydroponics, we can produce forage including corn, barley, oats, sorghum, rye, alfalfa and triticale. In summary, hydroponic forage is a production model that can maintain continuous production throughout the year, produce high-quality fresh forage, and have high land resource utilization efficiency. It can support regional livestock farms to complete self-sufficiency in some high-quality feed, and has high practical significance and economic value.

[0004] After searching, relevant patents have been disclosed about hydroponic forage systems. For example, patent CN116138153A discloses a continuous hydroponic forage production system and production method; patent CN113207661A discloses a hydroponic forage system integrated device and application suitable for high-cold and high-altitude areas; patent CN117898203A discloses a three-dimensional circulating forage hydroponic device; patent CN113273485A discloses a plant hydroponic production system. And patent CN115072298A discloses a double-helix tower forage growth and transportation system.

[0005] The above patents all disclose relevant technical improvements on the hydroponic forage system, but when the forage reaches the stage of finished grass, the forage needs to be harvested in time, but the above patents do not disclose the corresponding harvesting method. Conventional methods generally use manual collection, which has low work efficiency and is time-consuming and labor-intensive. In addition, the planting tray needs to be cleaned before it can be used before the next cultivation. Therefore, how to ensure the automation of the forage feeding process and the good connection with the cleaning process to improve production efficiency is a problem that needs to be solved at present.

[0066] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0067] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0068] The utility model is further described below in conjunction with specific embodiments.

[0069] like Figure 1 , Figure 2 As shown, a hydroponic forage production system of the present embodiment includes a conveyor line 1 for conveying planting trays 2, and along the conveying direction of the conveyor line 1 there are provided a tray cleaning station, a germination and tray loading station, a paving station, a forage growing station and a forage collecting station.

[0070] Among them, a cleaning machine 7 is provided at the tray cleaning station, which is used to clean the empty tray after collecting the forage grass. The cleaned planting tray 2 is transported to the germination tray loading station, where a germination device 3 is provided, which is used to soak and germinate the forage grass seeds, and complete the tray loading operation of the germinated seeds. The seeds after tray loading are transported to the paving station, where a vibrating device 6 is provided, which is used to pave the seeds in the planting tray 2. The planting tray 2 after the paving operation is further transported to the forage grass growth station, which is provided with a growth tower 4 to complete the growth process of the forage grass seeds. Finally, the planting tray 2 loaded with mature forage grass is transported to the turning station, and under the action of the turning machine 5, the forage grass collection operation is completed, and the empty planting tray 2 is transferred to the tray cleaning station to complete a cycle.

[0071] Specifically, the conveyor line 1 includes two chain plate lines arranged in parallel. Among them, the cleaning machine 7 and the germination device 3 share one chain plate line, and the growth tower 4 and the turning machine 5 share another chain plate line. The cleaning machine 7 and the turning machine 5 are located at the corresponding ends of the two chain plate lines, and the vibrating device 6 is located between the ends of the other ends of the two chain plate lines.

[0072] In addition, since the germination of seeds generally takes 1-3 days, and the growth of grass generally takes 5-10 days, for this reason, the germination device 3 and the growth tower 4 in this embodiment can be provided with multiple groups.

[0073] refer to Figure 3 , Figure 4As shown, the turning machine 5 includes a mounting platform 51 and a grass disc turning device. The end of the conveyor line 1 extends into the notch on the mounting platform 51, and two sets of grass disc turning devices are arranged on the mounting platform 51. The first set of grass disc turning devices is located at the end of the conveyor line 1, and is used to collect the grass and put the empty disc back to the original position; the second set of grass disc turning devices is located on the side of the conveyor line 1 close to the cleaning machine 7, and is used to transfer the empty planting disc 2 to the grass disc cleaning station.

[0074] Specifically, the grass tray flipping device includes a clamping mechanism 52 for clamping the planting tray 2 and a flipping mechanism 53 for driving the clamping mechanism 52 to flip. Among them, the clamping mechanism 52 includes a frame 521 and a clamping member 522. The frame 521 is a rectangular structure surrounded by four square tubes, and an inner frame is formed in the rectangular structure. The overall size of the inner frame needs to be larger than the size of the planting tray 2, that is, the length of the inner frame is larger than the length of the planting tray 2, and the width of the inner frame is larger than the width of the planting tray 2, so as to ensure that the frame 521 can put the planting tray 2 inside, and then perform a clamping operation from the side of the planting tray 2 through the clamping member 522.

[0075] The flip mechanism 53 includes a rotating shaft 531 and a driving source for driving the rotating shaft 531. The rotating shaft 531 is rotatably arranged on the mounting platform 51 through a bearing mounting seat 532. Preferably, the driving source is a reduction motor, and the output shaft of the motor is a hollow shaft. The rotating shaft 531 can be directly sleeved in the hollow shaft, and then the connection is completed through keyway matching, so that the assembly operation between the two is more convenient.

[0076] refer to Figure 5 As shown, the planting tray 2 in this embodiment not only serves as a transport carrier for seeds and grass, but also undertakes the work of seed germination until the grass matures. Therefore, the planting tray 2 should have good wear resistance, corrosion resistance, etc., and the advantages of light weight. Preferably, the planting tray 2 is made of plastic, such as POM, PTFE (polytetrafluoroethylene), etc.

[0077] Specifically in this embodiment, the planting tray 2 is made of polytetrafluoroethylene, and its overall size is 790mm*490mm*72mm. In addition, reinforcing ribs are provided around the outer frame of the planting tray 2 to further improve the overall strength of the planting tray 2 and extend its service life. At the same time, a step is formed on the reinforcing ribs to facilitate the clamping operation of the clamping member 522.

[0078] As a preferred embodiment, the clamping members 522 are arranged in pairs on opposite sides of the frame 521, and are used to clamp and release the planting tray 2 from opposite sides. The clamping members 522 include a clamping plate and a cylinder for driving the clamping plate to retract and move. The cylinder is arranged on the frame 521, and the clamping plate is located in the inner frame of the frame 521. Of course, the cylinder can also be replaced by an oil cylinder, an electric push rod, or other structures that can realize the retraction and movement of the clamping plate.

[0079] Preferably, both ends of the clamping surface of the splint have an extension section, and the free ends of the two extension sections are distributed away from each other. During the clamping operation, one extension section is clamped on the upper end surface of the planting tray 2, and the other extension section is clamped on the step on the outer periphery of the planting tray 2 to ensure the stability of the clamping of the planting tray 2. Compared with the conventional method of clamping from the top and bottom of the planting tray 2, the clamping method of the top plus the middle part is adopted in this embodiment, which can effectively avoid the interference between the splint and the bottom of the conveyor line 1. At the same time, in order to reduce the damage caused by the splint to the planting tray 2 during the clamping operation. The splint can be made of elastic material, such as rubber or silicone.

[0080] In addition, in order to enable the planting tray 2 to accurately stay at the forage collection station, it is convenient for the clamping operation of the clamping member 522. A stop plate 54 and a position sensor 55 are provided on the installation platform 51 at the end of the conveyor line 1. Among them, the stop plate 54 is used to stop the planting tray 2 after it moves into place to prevent the planting tray 2 from continuing to move so that it can accurately stay at the forage collection station. The position sensor 55 is preferably a photoelectric sensor, which is used to sense whether the planting tray 2 is located at the forage collection station, and then decide whether to start the subsequent flipping and clamping operations.

[0081] A hydroponic forage grass production system of this embodiment has the following forage grass collection process: the conveyor line 1 moves the planting tray 2 carrying mature forage grass to the stop plate 54 and stops at this point; at this point, the position sensor 55 senses that the planting tray 2 is located at the forage grass collection station, and the first flip device is activated: the flip mechanism 53 drives the clamping mechanism 52 to rotate, so that the planting tray 2 is located in the inner frame of the frame 521; then, the clamping member 522 clamps from the opposite side of the planting tray 2; then, the flip mechanism 53 drives the entire clamping mechanism 52 to flip 180°, and the forage grass falls off from the planting tray 2 under the action of gravity, completing the forage grass unloading operation; then, the first flip device puts the empty planting tray 2 back to its original position. Then, the second flip device is activated to clamp and flip the empty planting tray 2, so that it is turned upside down at the tray cleaning station, and then transported by the conveyor line 1 to the cleaning machine 7 for cleaning operation.

[0082] A hydroponic forage production system of the present embodiment, through the setting of the turning machine 5, can transfer the empty tray to the subsequent tray cleaning station after the planting tray 2 is turned over and unloaded, so as to achieve a good connection between the unloading process and the cleaning process; at the same time, the second grass tray turning device turns the empty planting tray 2 upside down at the tray cleaning station, which is also conducive to the subsequent cleaning operation.

[0083] In this embodiment, as an implementation method of the germination device 3, refer to Figure 6 , Figure 7 As shown, the germination device 3 includes a frame, a germination tank 31 arranged on the frame, and a driving mechanism 32. The germination tank 31 is used to carry the forage seeds and complete the soaking and germination of the seeds therein; the driving mechanism 32 is used to drive the germination tank 31 to rotate.

[0084] The germination tank 31 is arranged horizontally on the frame, and a material slot 311 is provided on its outer peripheral wall along its axial direction. In the initial stage, the material slot 311 is located at the top of the germination tank 31, and the forage seeds enter the germination tank 31 from the material slot 311 for soaking and germination operation; during the germination process, the germination tank 31 is driven by the driving mechanism 32 to swing to improve the accumulation of seeds in the germination tank 31. After the germination is completed, the driving mechanism 32 drives the germination tank 31 to continue to rotate, so that the material slot 311 on the germination tank 31 rotates to the bottom, and the seeds in the germination tank 31 fall from the material slot 311, completing the seed discharge operation. By setting the material slot 311, the seed discharge operation can be made more thorough, thereby minimizing the residual seeds in the tank body after discharge.

[0085] In order to facilitate the water replenishment operation in the germination tank 31, in this embodiment, a water replenishment pipe 312 is also provided in the germination tank 31. The part of the water replenishment pipe 312 located in the germination tank 31 is provided with multiple nozzles, and the multiple nozzles are spirally distributed to facilitate the cleaning operation of the inside of the tank after the feeding is completed. At the same time, there is also an integrated temperature, humidity and carbon dioxide sensor on the water replenishment pipe 312 to monitor the environment in the germination tank 31.

[0086] In this embodiment, in order to allow the germinated seeds in the germination tank 31 to be discharged as cleanly as possible, the length of the trough opening 311 (the length extending along the axial direction of the germination tank) should be as long as possible. However, in this embodiment, in order to ensure the degree of automation of the entire production line, it is necessary to use a planting tray 2 to divide the seeds into trays during the seed discharge process, and then directly carry out hydroponics in the whole pot. This makes it difficult for the overly long trough opening 311 to form a good match with the planting tray 2. To this end, in this embodiment, a conveying component 33 is provided at the trough opening 311 to solve the above problem.

[0087] refer to Figure 7As shown, the conveying assembly 33 includes a cover body 331 and a conveying screw 332. The cover body 331 is arranged at the material slot 311, and a material inlet and outlet 333 is arranged near the end thereof. The conveying screw 332 is located inside the cover body 331, and its connecting end extends to the outside of the cover body 331 and is connected to a driving source.

[0088] During feeding, the material slot 311 and the conveying assembly 33 are located at the top of the germination tank 31. At this time, the seeds to be soaked can directly enter the germination tank 31 through the inlet and outlet 333. At the same time, the germination tank 31 is driven by the driving mechanism 32 to swing in a small range to disperse the seeds, and then germinates while swinging. After the germination is completed, the inlet and outlet 333 rotates to the bottom with the germination tank 31. At this time, the seeds fall into the cover body 331 through the material slot 311. The seeds located at the inlet and outlet 333 in the cover body 331 fall into the corresponding planting tray 2; the seeds located in other places will eventually fall into the planting tray 2 through the inlet and outlet 333 under the transportation of the conveying screw 332, completing the seed discharge operation and tray loading operation.

[0089] In this embodiment, through the arrangement of the conveying assembly 33, when the trough opening 311 rotates to the bottom, the seeds in the cover body 331 are conveyed to the inlet and outlet opening 333 by the conveying screw 332, and then discharged. This design can not only ensure the smooth discharge of the seeds in the germination tank 31, but also make the discharge position relatively concentrated, which can be well matched with the planting tray 2 below.

[0090] As mentioned above, in order to allow the seeds in the germination tank 31 to be discharged as cleanly as possible, the length of the slot opening 311 should be as long as possible, and the ideal state is that the slot opening 311 runs through the entire axial direction of the germination tank 31. However, in the actual operation, a certain gap needs to be left between the two ends of the slot opening 311 and the corresponding ends of the germination tank 31. For example, in this embodiment, in order to avoid interference between the driving source and other components during the rotation of the germination tank 31, the driving source is directly set on the outer peripheral wall of the germination tank 31, so that there will be a large gap between the end of the germination tank 31 and the slot opening 311.

[0091] Due to the existence of the above-mentioned gap, seeds may accumulate in the corresponding area of ​​the germination tank 31, thereby affecting the seed discharge operation. Therefore, the present embodiment further optimizes the structure inside the germination tank 31 to solve the problem that seeds are easily accumulated near the end of the germination tank 31.

[0092] refer to Figure 7As shown, a guide plate 35 is provided near the end of the germination tank 31. The guide plate 35 is in the shape of a pot cover. The opening direction of the guide plate 35 faces the center of the germination tank 31, and the outer edge of the opening end is aligned with the end of the slot 311. Through the provision of the guide plate 35, the seeds can slide along the curved surface section of the guide plate 35 to the slot 311, thereby effectively avoiding the accumulation of seeds in the germination tank 31, which is conducive to ensuring the complete discharge of the seeds.

[0093] As another embodiment of the germination device 3, refer to Figure 8 , Fig. 9 As shown, a quantitative component 34 is provided at the inlet and outlet 333 for realizing the quantitative seed feeding operation. The quantitative component 34 includes a frame 341 and a plug plate 342. The frame 341 is a rectangular structure that penetrates from top to bottom. The interior of the frame 341 is divided into two parts, left and right, by a partition 343, which are a feeding channel on the left and a non-feeding channel on the right (with a diameter of 1 / 40 mm). Fig. 9 The material discharge channel is located on the material inlet and outlet 333.

[0094] The plugboard 342 is provided with two pieces at the top and bottom, and is slidably provided in the frame 341, and can switch back and forth between the feeding channel and the non-feeding channel. When the two plugboards 342 are located in the feeding channel at the same time, a certain amount of storage space is formed between the two plugboards 342 to realize the quantitative discharge of seeds.

[0095] For the convenience of description, the internal area of ​​the frame 341 is divided into two layers, the plug-in board 342 located in the upper layer is recorded as an upper plug-in board 342, and the plug-in board 342 located in the lower layer is recorded as a lower plug-in board 342.

[0096] As a sliding method, two groups of rails 347 distributed up and down are provided in the unloading channel, one end of the rail 347 extends into the non-unloading channel, and the two plug plates 342 are driven by their respective driving sources to switch back and forth between the unloading channel and the non-unloading channel along their respective rails 347.

[0097] In order to facilitate the adjustment of the size of the quantitative storage space formed between the two plug boards 342 to achieve the quantitative feeding operation of seeds of different weights, the position of the track 347 in the vertical direction is adjustable. For example, the track 347 is connected to the inner wall of the frame 341 through the waist-shaped hole thereon. The position of the track 347 in the vertical direction can be adjusted through the waist-shaped hole, thereby changing the distance between the two plug boards 342 to form quantitative storage spaces of different sizes.

[0098] The basic process of quantitative feeding operation of a hydroponic forage production system of this embodiment is as follows: the upper plug plate 342 first moves to the non-feeding channel; at this time, the upper end inlet of the feeding channel is in an open state, and the seeds fall onto the lower plug plate 342 through the inlet; then, the upper plug plate 342 slides into the feeding channel to separate the excess seeds in the feeding channel; and at this time, the quantitative storage space between the two plug plates 342 is full of seeds. Finally, the lower plug plate 342 slides into the non-feeding channel, the lower end outlet of the feeding channel is opened, and the seeds in the quantitative storage space fall into the corresponding planting tray 2 to complete a quantitative feeding operation.

[0099] As another embodiment of the quantitative component 34, refer to Figure 10-12 As shown, the quantitative component 34 includes a frame 341 and a feed hopper 344, an insert plate 342 and a bottom plate 345 arranged inside the frame 341, and the feed hopper 344, the insert plate 342 and the bottom plate 345 are distributed in sequence up and down.

[0100] The feed hopper 344 is located at the upper layer and has a feed port. The bottom plate 345 is located at the lower layer and has a discharge port, and the discharge port and the feed port are completely offset, that is, the projections of the two in the vertical direction have no overlap.

[0101] The insert plate 342 is located in the middle layer, and has a receiving groove 346 that runs through it from top to bottom. The insert plate 342 is slidably arranged in the frame 341 and can move horizontally relative to the feed hopper 344 and the bottom plate 345, so that the receiving groove 346 can switch back and forth between the feed port position and the discharge port position.

[0102] Preferably, the insert plate 342 is slidably disposed on the base plate 345 via a linear guide pair, and the linear guide pair may be any one of a guide rail and slider match, a guide rod and sleeve match, or a guide rod and groove match.

[0103] When the receiving groove 346 moves to the bottom of the feed port, a feeding channel is formed between the two, and the feeding channel is open at the upper end and closed at the lower end; the seeds are placed in the receiving groove 346 through the feeding channel and fill up the receiving groove 346. As the plug plate 342 continues to move, the seeds that exceed the height of the receiving groove 346 are stopped outside the receiving groove 346 by the lower end of the feed hopper 344; at this time, a fixed volume quantitative storage space is formed between the receiving groove 346 and the bottom of the feed hopper 344 and the top of the bottom plate 345, and the quantitative storage space is full of seeds. When the receiving groove 346 moves to the top of the discharge port, the two form a discharge channel with a closed upper end and an open lower end, and the seeds in the quantitative storage space are discharged through the discharge channel, thereby realizing the quantitative feeding operation of seeds.

[0104] As a preferred method, a drainage groove 349 is also slidably provided in the frame 341, and the drainage groove 349 is provided on the side of the feed hopper 344. The two are connected as a whole through the side plate 348, and the side plate 348 and the inner wall of the frame 341 are slidably connected through a linear guide pair.

[0105] When the inside of the tank needs to be cleaned after unloading, the driving source drives the drainage trough 349 and the feed hopper 344 to move simultaneously, so that the drainage trough 349 moves to the position where the feed hopper 344 was originally located. At this time, the drainage trough 349 is located below the inlet and outlet 333, and can collect and discharge the sewage discharged from the tank.

[0106] In this embodiment, as an implementation method of the driving mechanism 32, refer to Figure 6 As shown, the driving mechanism 32 includes a supporting assembly 321 and a driving assembly 322. Among them, the supporting assembly 321 is provided with 4 groups and is distributed on the frame in a rectangular shape. The supporting assembly 321 is used to roll support the germination tank 31. The driving assembly 322 is also provided on the frame to drive the germination tank 31 to rotate.

[0107] refer to Fig.13 , Fig.14 As shown, the support assembly 321 includes a mounting frame 3211 and a V-shaped connecting portion 3212 rotatably disposed on the mounting frame 3211. The middle portion of the V-shaped connecting portion 3212 is rotatably connected to the mounting frame 3211, and the opening of the V-shaped connecting portion 3212 faces away from the mounting frame 3211. At the same time, both ends of the connecting portion 3212 are rotatably connected to a supporting portion 3213, and the supporting portion 3213 is used to provide rolling support for the germination tank 31.

[0108] In this embodiment, by setting the support assembly 321, the support part 3213 supports the germination tank 31, and the two are in rolling friction, thereby reducing the friction resistance of the germination tank 31 during the rotation process. In addition, the connection part 3212 is rotatable, which is conducive to adjusting the concentricity of the germination tank, thereby ensuring the stability of the germination tank 31 during the rotation process.

[0109] Specifically, the mounting frame 3211 includes a base plate and a connecting ear vertically arranged on the base plate. The base plate can be installed on the frame by bolts or direct welding to provide a stable installation foundation for the entire support assembly 321. Two connecting ears are provided and are arranged in parallel relative to each other. At the same time, the connecting ear is also provided with a mounting hole for connecting the V-shaped connecting portion 3212.

[0110] The connecting portion 3212 includes a pair of V-shaped connecting plates arranged in parallel, and the opening of the V-shaped connecting plates is greater than 90 degrees. At the same time, a mounting hole for the pin to pass through is opened in the middle of the V-shaped connecting plate, and a mounting hole for mounting the support portion 3213 is provided at each end.

[0111] The support part 3213 includes a roller surface and ribs arranged at both ends of the roller surface. A connecting shaft is arranged on one end of the rib away from the roller surface. During assembly, the support part 3213 is located between two connecting plates, and the connecting shafts on both sides thereof are respectively inserted into the mounting holes at the ends of the corresponding connecting plates, so that the rotational connection between the support part 3213 and the connecting part 3212 can be completed. Then, the two connecting plates are respectively provided with corresponding connecting ear sides, and the rotational connection between the mounting frame 3211 and the connecting part 3212 can be completed by passing the pin through the corresponding mounting holes.

[0112] In this embodiment, the driving assembly 322 can adopt a chain driving assembly, which includes a motor, a small sprocket, a large sprocket and a chain. The motor is arranged on a frame, the small sprocket is connected to the output end of the motor, the large sprocket is arranged at the end of the germination tank 31, and the large and small sprockets are connected by a chain, and the chain can be equipped with a tension wheel.

[0113] At the same time, an annular boss 313 is provided at each end of the germination pot 31. During assembly, the annular boss 313 is inserted between the two ribs on the corresponding support portion 3213 to achieve rolling cooperation between the germination pot 31 and the support assembly 321. This design not only reduces the friction resistance of the germination pot 31 during rotation, but also effectively prevents the germination pot 31 from axially running through the mutual cooperation between the annular boss 313 and the ribs, thereby ensuring the stability of the germination cylinder 2 during rotation.

[0114] In addition, in order to facilitate the effective control of the rotation range of the germination tank 31, that is, the small swing during the germination process and the 180° rotation during the discharge operation. Fig.14 As shown, in this embodiment, a sensing sheet 36 is provided on the frame, a position sensor 37 is provided on the germination tank 31, and the position sensor 37 is connected to a PLC controller. The rotation angle of the germination tank 31 at different stages is controlled by the cooperation between the sensing sheet 36 and the position sensor 37. Among them, at least three position sensors 37 are provided, two of which are used to control the swing angle of the germination tank 31 during the germination process to prevent the rotation angle of the germination tank 31 from being too large. The other is used to control the position of the material slot 311 during the discharging operation to ensure that the material slot 311 is located at the bottom, thereby facilitating the discharging.

[0115] refer to Fig.15As shown, as an embodiment of the vibrating device 6, the vibrating device 6 includes a base 63 and a vibration mechanism 61 and a flattening mechanism 62 arranged on the base 63. Among them, the vibration mechanism 61 is used to support the planting tray 2 carrying seeds and drive the planting tray 2 to vibrate. The flattening mechanism 62 is located above the vibration mechanism 61 and is used to flatten the seeds accumulated in the planting tray 2. At the same time, the vibration mechanism 61 can move vertically relative to the flattening mechanism 62 so that the scraper 621 of the flattening mechanism 62 can be inserted into or leave the planting tray 2.

[0116] Specifically, the base 63 includes two brackets arranged at intervals, each bracket is provided with a vibration mechanism 61, and the two vibration mechanisms 61 are arranged opposite to each other and are respectively used to support the two ends of the planting tray 2. The main part of the flattening mechanism 62 is located above the vibration mechanism 61.

[0117] refer to Fig.16 As shown, the flattening mechanism 62 includes a gantry 622 and two sets of flattening components arranged on the gantry 622. The two uprights of the gantry 622 are respectively arranged on corresponding brackets and are located outside the vibration mechanism 61, that is, on the side where the two vibration mechanisms are away from each other, and the crossbeam of the gantry 622 is located above the vibration mechanism 61.

[0118] The flattening assembly includes a scraper 621 and a driving source for driving the scraper 621 to perform horizontal reciprocating motion. The driving source is arranged near the end of the crossbeam, and the driving source can be any one of an air cylinder, an oil cylinder or an electric push rod. The scraper 621 is slidably connected to the crossbeam through a linear guide pair, and the linear guide pair can be any one of a guide rail slider match, a guide rod guide sleeve match or a guide rod guide groove match.

[0119] Preferably, a limit plate 623 is provided on the gantry 622, and the limit plates 623 are arranged in pairs, respectively located on both sides of the planting tray 2, for adjusting the posture of the planting tray 2 so that the scraper 621 can smoothly enter the planting tray 2.

[0120] The limiting plate 623 is L-shaped as a whole, and its horizontal section is used to connect the crossbeam; the vertical section extends downward, and its end has a guide section extending outward, which is used to fine-tune the posture of the planting tray 2. Of course, the limiting plate 623 can also be connected to a driving source, and a group of limiting plates 623 arranged in pairs can form a centering mechanism, which can also adjust the posture of the planting tray 2.

[0121] refer to Fig.17 As shown, the vibration mechanism 61 includes a mounting plate 611 and a support plate 612. The mounting plate 611 and the support plate 612 are connected via an elastic connector 613, and a vibrator 614 is disposed on the support plate 612.

[0122] Preferably, the vibrator 614 is arranged at the central position of the bottom of the support plate 612 to ensure more uniform vibration of the support plate 612. The overall shape of the support plate 612 is a "C" - shaped structure, and its top can be used to limit the height of the planting tray 2 during vibration; its side is used to limit the end of the planting tray 2.

[0123] Meanwhile, the elastic connecting member 613 is a spring. Positioning columns are provided at corresponding positions on the opposite surfaces of the mounting plate 611 and the support plate 612. The two ends of the spring are respectively sleeved on the corresponding positioning columns. Through the setting of the positioning columns, on the one hand, the lateral swing amplitude of the support plate 612 during vibration can be reduced; on the other hand, the up - and - down vibration amplitude of the support plate 612 can be controlled to prevent interference between the vibrator 614 and the lower mounting plate 611 due to excessive up - and - down vibration amplitude.

[0124] In addition, in order to enable the vibration mechanism 61 to move in the vertical direction, the mounting plate 611 is connected to a driving source, and the mounting plate 611 is slidably connected to the bracket through a linear guide pair. Meanwhile, in this embodiment, a manipulator 8 can be equipped at the leveling device 6 to complete the switching of the planting tray 2 between the leveling device 6 and the conveyor line 1.

[0125] In a hydroponic forage production system of this embodiment, the process of seed leveling operation is as follows. Before the scraping action, the scrapers 621 of the two leveling components are both in the starting position; at this time, the two scrapers 621 are closely adjacent to each other and are located at the central position of the planting tray 2, that is, the central position of the piled - up seeds. When the scraping action is carried out, the vibration mechanism 61 drives the planting tray 2 to move upward so that the scraper 621 can be inserted into the piled - up seeds. Of course, a certain gap needs to be left between the scraper 621 and the bottom wall of the planting tray 2, and this gap is the thickness of the seeds in the planting tray 2 after paving. Then the scrapers 621 move away from each other under the drive of their respective driving sources, spreading the seeds from the middle to both sides until the scrapers 621 move to the end position, that is, when they are close to the inner end face of the planting tray, they stop moving; finally, the vibration mechanism 61 drives the planting tray 2 to move downward, and the scrapers 621 return to the starting position, thus completing one scraping operation; then, the vibrator 614 starts, driving the planting tray 2 to vibrate up and down to further ensure the uniformity of the distribution of the seeds in the planting tray 2.

[0126] In this embodiment, through the mutual cooperation of the vibration mechanism 61 and the leveling mechanism 62, not only can the distribution of the seeds in the planting tray 2 be made more uniform, but also the seeds can be spread as much as possible to cover the entire planting tray 2, so as to improve the utilization rate of the internal space of the planting tray 2. At the same time, in this embodiment, by the method of leveling first and then vibrating, the time required for the seed leveling operation can be greatly reduced, and the work efficiency can be improved.

[0127] In summary, the hydroponic forage production system of the utility model can form a closed loop from seed germination, quantitative loading, flattening, growth, collection, and empty tray cleaning through the mutual cooperation between different workstations, and each process can ensure good connection, which can effectively reduce the degree of labor and is beneficial to improving work efficiency.

[0128] In addition, it should be noted that the growth tower 4 and the cleaning machine 7 in this embodiment can both adopt existing technologies. For example, the growth tower 4 can use the double helix tower in CN115072298A. At the same time, a manipulator 8 can be provided at the inlet and outlet of the double helix tower to transfer the planting tray 2 carrying seeds on the conveyor line 1 to the double helix tower, and to transfer the mature forage together with the planting tray 2 to the conveyor line 1. The cleaning machine 7 can use the forage planting tray cleaning machine in CN115090635A. Since the planting tray 2 is in an inverted state after cleaning, it needs to be flipped. Here, the above-mentioned grass tray flipping device or the squirrel cage flipping machine in the prior art can be used.

[0129] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
