[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The embodiment of the present invention provides a cultivation device for forage planting, such as Figure 1-14 As shown, the cultivation device for forage planting comprises: a solution box 1 and side support plates 2 respectively fixedly installed on both sides of the solution box 1, the solution box 1 is used to store hydroponic solution; a plurality of track plates 3 are fixedly installed on one side of the two side support plates 2 close to each other, the plurality of track plates 3 are arranged in parallel in groups, the plurality of groups of track plates 3 are evenly arranged in the longitudinal direction, and a detachable hydroponic trough 4 is placed on the plurality of groups of track plates 3 for hydroponic cultivation of forage, and the bottom of the hydroponic trough 4 has a plurality of through holes 5 for discharging excess hydroponic solution; the bottom of the plurality of track plates 3 Each side is provided with a mounting knife rack 6 fixedly connected to the corresponding side support plate 2, and multiple mounting knife racks 6 are arranged in parallel in groups, and multiple groups of mounting knife racks 6 can be detachably installed with out-groove root cutting knives 7, and multiple out-groove root cutting knives 7 are respectively fitted with the bottom of the corresponding hydroponic trough 4, and the out-groove root cutting knives 7 are located on the taking-out side of the hydroponic trough 4, and are used to cut off the roots passing through the through hole 5 when taking out the hydroponic trough 4; a water spraying and lighting mechanism, which is arranged on the solution tank 1 and the two side support plates 2, and is used to provide the solution and light required for hydroponic cultivation of forage.

[0021] In this embodiment, the preparation stage: first, inject an appropriate amount of hydroponic solution into the solution tank 1 to ensure that the amount of solution in the solution tank 1 can meet the needs of forage growth. Then, the forage seeds are spread in the removable hydroponic tank 4 according to the predetermined planting density. The bottom of each hydroponic tank 4 is designed with multiple through holes 5 to discharge excess hydroponic solution during the growth of forage. Then, the hydroponic tank 4 is stably placed between the support plates 2 on both sides along the track plate 3 to ensure that the hydroponic tank 4 can be stably fixed on the track.

[0022] Growth stage: During the growth of grass, the water spraying and lighting mechanism will automatically provide the grass with the required hydroponic solution and light according to the preset program. The solution is evenly sprayed on the grass through the delivery system of the solution tank 1, and the light is provided by a specific light source device to meet the photosynthesis needs of the grass. At the same time, as the grass grows, part of the root system may pass through the through hole 5 at the bottom of the hydroponic tank 4.

[0023] Harvest stage: When the grass grows to a predetermined height and density, it is ready to be harvested. At this time, the operator can pull the hydroponic tank 4 out of the side support plate 2 along the track plate 3. During the pulling process, the root cutting knife 7 outside the tank will automatically cut off the roots passing through the through hole 5, ensuring that the grass can be completely separated from the hydroponic tank 4 without the grass being loosened due to the entanglement of the roots. The cut grass can be directly collected and processed.

[0024] This solution uses a detachable hydroponic trough 4 and a root cutting knife 7 outside the trough to ensure that during the harvesting process, only the roots that pass through the through holes 5 are cut off, and the roots inside the hydroponic trough 4 will not be damaged, thereby reducing losses and facilitating subsequent manual removal of the entire grass, thereby achieving efficient harvesting of grass. Compared with the traditional pulling removal method, this method greatly reduces manual labor and improves harvesting efficiency.

[0025] The water spraying and lighting mechanism can provide the right amount of solution and light according to the needs of grass growth, creating an ideal growth environment for the grass. This helps to promote the rapid growth and development of grass, and improve the quality and yield of grass. At the same time, by accurately controlling the supply of solution and light, it can also reduce the waste of resources and environmental pollution.

[0026] In a further preferred embodiment of the present invention, the water spraying and lighting mechanism includes a plurality of hollow plates 8 fixedly mounted on one side of the two side support plates 2 close to each other, the plurality of hollow plates 8 are respectively and staggeredly located directly above the plurality of hydroponic tanks 4, the bottoms of the plurality of hollow plates 8 are fixedly mounted with a plurality of atomizing nozzles 9 and LED lamps 10 corresponding to the hydroponic tanks 4, the plurality of atomizing nozzles 9 and the plurality of LED lamps 10 are staggeredly arranged, the solution tank 1 has a liquid storage chamber 11 for storing a hydroponic solution, a water pump 12 is arranged in the liquid storage chamber 11, and the discharge end of the water pump 12 is connected to the plurality of hollow plates 8 by a liquid supply pipe 13 for supplying a hydroponic solution.

[0027] In this embodiment, the water spraying and lighting mechanism includes a plurality of hollow plates 8 fixedly mounted on the side of the two side support plates 2 close to each other, and these hollow plates 8 are staggered and located directly above the hydroponic tank 4. A plurality of atomizing nozzles 9 and LED lamps 10 corresponding to the hydroponic tank 4 are fixedly mounted at the bottom of each hollow plate 8, and the atomizing nozzles 9 and LED lamps 10 are staggered. The water pump 12 in the solution tank 1 is connected to the plurality of hollow plates 8 through a liquid supply pipe 13, and is used to supply the stored hydroponic solution to the atomizing nozzles 9.

[0028] When in use, the water pump 12 in the solution tank 1 is started to draw the hydroponic solution from the liquid storage chamber 11, and the hydroponic solution is transported to each hollow plate 8 through the liquid supply pipe 13. The atomizing nozzle 9 at the bottom of the hollow plate 8 atomizes the hydroponic solution and sprays it evenly onto the forage.

[0029] At the same time, the LED lamp 10 provides necessary illumination for the grass to meet its photosynthesis needs.

[0030] The staggered arrangement of the atomizing nozzles 9 and the LED lights 10 ensures that the grass can obtain uniform spraying of the hydroponic solution and sufficient light at the same time, providing ideal conditions for the growth of the grass.

[0031] The combination of the water pump 12 and the liquid supply pipe 13 enables the hydroponic solution to be quickly and evenly transported to each hollow plate 8 and sprayed onto the grass through the atomizing nozzle 9, thereby improving the utilization rate of the solution and the growth efficiency of the grass.

[0032] In a further preferred embodiment of the present invention, a drain pipe 14 is provided at the bottom of the side of the solution tank 1 , the drain pipe 14 is communicated with the liquid storage chamber 11 , and a valve is provided on the drain pipe 14 .

[0033] In this embodiment, a drain pipe 14 is additionally provided at the bottom of the side of the solution tank 1, and the drain pipe 14 is connected to the liquid storage chamber 11 inside the solution tank 1. A valve is also provided on the drain pipe 14 to control the opening and closing of the drain pipe 14.

[0034] During the use of the device, when the hydroponic solution in the solution tank 1 needs to be replaced or the liquid storage chamber 11 needs to be cleaned, the operator can open the valve on the drain pipe 14 to allow the waste liquid or impurities in the liquid storage chamber 11 to be smoothly discharged through the drain pipe 14. After the drainage is completed, the valve is closed and new hydroponic solution can be re-injected into the liquid storage chamber 11.

[0035] In a further preferred embodiment of the present invention, a plurality of root receiving grooves 15 are fixedly installed on one side of the two side support plates 2 close to each other, and the plurality of root receiving grooves 15 are respectively located below the plurality of root cutting knives 7 outside the grooves for receiving the cut roots.

[0036] In this embodiment, a plurality of root receiving grooves 15 are fixedly installed on the side where the two side support plates 2 are close to each other, and these root receiving grooves 15 are respectively located below a plurality of out-groove root cutting knives 7. The root receiving grooves 15 are designed to receive the grass roots cut by the out-groove root cutting knives 7.

[0037] During the forage harvesting process, after the forage roots are cut by the root cutting knife 7 outside the groove, the cut roots will then fall into the root receiving groove 15 located below it. The operator can conveniently collect the roots in the root receiving groove 15 for subsequent processing or utilization.

[0038] The root receiving groove 15 is provided to provide a convenient root collection method for operators. The cut roots fall directly into the receiving groove, avoiding the root system from being scattered or lost, and improving the collection efficiency.

[0039] The design of the root receiving slot 15 makes the grass harvesting process smoother and more efficient. The operator does not need to spend extra time and energy to collect scattered roots during the harvesting process, so that the operator can focus more on cutting and collecting grass.

[0040] The present invention not only improves the functionality of the device, but also enhances its practicability by adding the design of the root access groove 15. This makes the device more in line with actual needs during forage planting and harvesting, and improves the overall user experience.

[0041] In summary, the present invention further optimizes the cultivation device for forage planting by providing the root access groove 15, improves the convenience of root collection and the efficiency of the harvesting process, and also enhances the practicality and functionality of the device.

[0042] In a further preferred embodiment of the present invention, a plurality of the hydroponic troughs 4 are each provided with an in-trough root cutting mechanism, the in-trough root cutting mechanism comprising two L-shaped knife racks 16 and an in-trough root cutting knife 17, the two L-shaped knife racks 16 are placed on both sides of the same hydroponic trough 4, the tops of the two L-shaped knife racks 16 extend outside the hydroponic trough 4 for extraction when taken out, the tops of the two L-shaped knife racks 16 are fixedly installed with fixing ears 18, the two side support plates 2 are located at the positions of the fixing ears 18 and are fixedly installed with positioning ears 19, the corresponding fixing ears 18 and the positioning ears 19 are detachably connected by fixing bolts 20 for fixing the position, the in-trough root cutting knife 17 is fixedly installed on the two L-shaped knife racks 16 located in the same hydroponic trough 4, the in-trough root cutting knife 17 is attached to the bottom inner wall of the hydroponic trough 4, the in-trough root cutting knife 17, the L-shaped knife rack 16 and the out-trough root cutting knife 7 are located at the same longitudinal position for synchronously cutting the roots.

[0043] In this embodiment, after the forage cultivation seeds are laid, the hydroponic trough 4 is placed on the track plate 3, and then the root cutting mechanism in the trough is buried in the seeds and the fixing ears 18 and the positioning ears 19 are fixed with fixing bolts 20, and then the seeds are repaved. During the growth of the forage grass, the forage grass covers the root cutting mechanism in the trough.

[0044] During the harvesting process, when the operator pulls out the hydroponic tank 4, the root system cutter 7 outside the tank below cuts off the exposed roots outside the bottom of the hydroponic tank 4. At the same time, since the root system cutter 17 inside the tank is fixed, the roots of the grass inside the hydroponic tank 4 are also cut off. The root system cutter 17 inside the tank and the root system cutter 7 outside the tank simultaneously cut off the grass roots. The cut roots are collected by the root receiving tank 15. After the cutting is completed, the operator removes the fixing bolts 20, removes the hydroponic tank 4 and the root system cutting mechanism inside the tank for cleaning or maintenance.

[0045] The cutting efficiency of the grass root system is improved by designing the synchronous cutting of the root system cutting mechanism inside the groove and the root system cutting knife 7 outside the groove.

[0046] The detachable connection design of the fixing bolt 20, the fixing ear 18 and the positioning ear 19 provides great convenience for the installation, disassembly and maintenance of the root cutting mechanism in the groove. The operator can easily perform these operations, reducing the difficulty and cost of the work.

[0047] By adding the design of the root cutting mechanism in the groove, the function of the cultivation device of the present invention is significantly improved.

[0048] In a further preferred embodiment of the present invention, the in-groove root cutting knife 17 is as wide as the two L-shaped knife holders 16 and the out-groove root cutting knife 7, and the blade surfaces of the in-groove root cutting knife 17 and the out-groove root cutting knife 7 are both facing the other side of the hydroponic tank 4.

[0049] In this embodiment, the width of the root cutting knife 17 in the groove is set to be equal to the width of the two L-shaped knife holders 16 and the root cutting knife 7 outside the groove to ensure consistency during cutting. In addition, the blades of the root cutting knife 17 in the groove and the root cutting knife 7 outside the groove are both facing the other side of the hydroponic groove 4, which means that when the hydroponic groove 4 is pulled out, the blades of the two cutting knives will directly act on the roots of the forage grass to achieve effective cutting.

[0050] During the process of forage planting and harvesting, the root system cutting knife 17 inside the trough works in coordination with the root system cutting knife 7 outside the trough. When the forage reaches the harvest period and the operator starts to pull out the hydroponic trough 4, the root system cutting knife 7 outside the trough cuts off the roots exposed at the bottom of the hydroponic trough 4. At the same time, since the root system cutting knife 17 inside the trough is firmly mounted on the L-shaped knife holder 16 and its blade faces the correct direction, when the hydroponic trough 4 continues to be pulled out, the root system cutting knife 17 inside the trough will also effectively cut off the forage roots inside the hydroponic trough 4. The synchronous action of the two cutting knives ensures the complete cutting of the forage roots and improves the harvesting efficiency.

[0051] In a further preferred embodiment of the present invention, the setting direction of the track plate 3 is consistent with the sliding direction of the hydroponic trough 4, and the setting direction of the track plate 3 is perpendicular to the setting direction of the root cutting knife 17 inside the trough and the root cutting knife 7 outside the trough.

[0052] In this embodiment, the setting direction of the track plate 3 is set to be consistent with the sliding direction of the hydroponic tank 4, which ensures that the hydroponic tank 4 can move smoothly on the track plate 3. At the same time, the setting direction of the track plate 3 is perpendicular to the setting directions of the root system cutting knife 17 in the tank and the root system cutting knife 7 outside the tank. This layout enables the root system of the forage grass to be cut more effectively when the hydroponic tank 4 slides along the track plate 3.

[0053] As the grass matures, when the operator is ready to harvest, he only needs to gently pull the hydroponic tank 4 along the direction of the track plate 3 to make it slide smoothly. In this process, the root cutting knife 17 inside the tank and the root cutting knife 7 outside the tank are perpendicular to the setting direction of the track plate 3, so they can accurately cut off the roots of the grass, ensuring that the harvested grass is intact and the roots are effectively removed.

[0054] In a further preferred embodiment of the present invention, the liquid supply pipe 13 has a plurality of branch pipes, and the plurality of branch pipes are respectively fixedly connected to the plurality of hollow plates 8 and communicated with the cavity of the hollow plates 8 .

[0055] In this embodiment, the liquid supply pipe 13 is designed to have a plurality of branch pipes, which are respectively fixedly connected to the plurality of hollow plates 8 and communicate with the cavities of the hollow plates 8. This design allows the nutrient solution to be evenly distributed to each hollow plate 8.

[0056] In a further preferred embodiment of the present invention, the opening width of the root access groove 15 is greater than the width of the root cutting knife 7 outside the groove, and the opening width of the root access groove 15 is equal to the bottom width of the hydroponic groove 4, and the positions correspond.

[0057] In this embodiment, the opening width of the root receiving groove 15 is set to be larger than the width of the root cutting knife 7 outside the groove to ensure that the cut roots can fall smoothly into the groove. At the same time, the opening width of the root receiving groove 15 is equal to the bottom width of the hydroponic groove 4, and the positions are corresponding. This design allows the cut roots to fall directly into the root receiving groove 15 when the hydroponic groove 4 is pulled out, which is convenient for subsequent collection and processing, and also convenient for receiving excess hydroponic solution, effectively reducing root loss and waste of hydroponic solution.

[0058] In a further preferred embodiment of the present invention, the hydroponic tank 4 has an outer edge, the outer edge of the hydroponic tank 4 is placed on the top of the corresponding track plate 3, and the side edge of the hydroponic tank 4 is in conflict with the side edge of the track plate 3.

[0059] In this embodiment, the hydroponic tank 4 is designed to have an outer edge that can be placed on the top of the corresponding track plate 3, and the side of the hydroponic tank 4 is tightly in contact with the side of the track plate 3. This design ensures the stability and firmness of the hydroponic tank 4 on the track plate 3, so that the hydroponic tank 4 can slide smoothly on the track.

[0060] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments: In another embodiment of the present invention, a reflux chamber 21 is further provided in the solution tank 1 , two sewage pipes 14 are provided, one of which corresponds to the reflux chamber 21 , and the plurality of root access troughs 15 are connected to the reflux chamber 21 by a return pipe 22 .

[0061] In this embodiment, a reflux chamber 21 is added inside the solution tank 1, and a sewage pipe 14 and a water return pipe 22 are provided in a matching manner. Specifically, the sewage pipe 14 is connected to the reflux chamber 21 for discharging the liquid in the reflux chamber 21; and the plurality of root receiving grooves 15 are connected to the reflux chamber 21 through their respective water return pipes 22, forming a complete liquid reflux system. This design aims to realize the recycling of nutrient solution, reduce resource waste, and maintain the stability of the cultivation environment.

[0062] During the forage planting process, the nutrient solution is first injected into the solution tank 1 and transported to the hydroponic tank 4 through the liquid supply system to provide nutrients for the forage, while the excess hydroponic solution is collected through the root access tank 15. At this time, the collected nutrient solution (which may contain waste or excess nutrients released by the roots) will flow back to the reflux chamber 21 through the return pipe 22. In the reflux chamber 21, these nutrient solutions can be simply filtered or precipitated to remove impurities and waste. Subsequently, the treated nutrient solution can be sent to the solution tank 1 again for recycling, and the sewage pipe 14 is used to regularly discharge the waste liquid that cannot be reused accumulated in the reflux chamber 21.

[0063] In another embodiment of the present invention, a water-passing net 23 is fixedly inlaid on the inner wall of the liquid storage chamber 11 and the reflux chamber 21 on one side, and a reset telescopic rod 24 is fixedly installed on the inner wall of the reflux chamber 21 on the side away from the liquid storage chamber 11. The reset telescopic rod 24 has a reset spring built in it. A compression net 25 is fixedly installed on one end of the reset telescopic rod 24 located on the water-passing net 23, and a filter material 26 is provided between the compression net 25 and the water-passing net 23 for filtering impurities.

[0064] In this embodiment, a water-passing net 23 is added between the liquid storage chamber 11 and the reflux chamber 21, and a resetting telescopic rod 24 and a compression net 25 connected thereto are installed in the reflux chamber 21, and a filter material 26 is filled between the two. This design aims to effectively remove impurities in the reflux nutrient solution by physical filtration to ensure the quality of the recycled nutrient solution.

[0065] During the forage planting process, the nutrient solution will carry impurities such as waste released by the roots during the recycling process. When these nutrient solutions containing impurities enter the reflux chamber 21 through the return pipe 22, they will first be filtered by the filter material 26. The filter material 26 is made of porous material and can absorb and intercept impurities, while the clean nutrient solution continues to flow to the liquid storage chamber 11 through the water mesh 23, ready to be pumped into the hydroponic tank 4 again. As the impurities accumulated on the filter material 26 increase, its filtration efficiency will gradually decrease. At this time, a replacement port (not shown) is provided on the solution tank 1 to take out and replace it.

[0066] By adding the water-passing net 23 and the filter material 26, impurities in the reflux nutrient solution are effectively removed, the quality of the recycled nutrient solution is ensured, and a purer growth environment is provided for the grass. The filter material 26 is fixed by utilizing the elastic restoring force of the resetting telescopic rod 24.

[0067] In another embodiment of the present invention, a sedimentation isolation bar 27 is fixedly installed on the inner wall of the bottom of the liquid storage chamber 11, and the height of the sedimentation isolation bar 27 is 3 to 5 cm.

[0068] In this embodiment, a sedimentation isolation bar 27 is added to the bottom of the liquid storage chamber 11. The sedimentation isolation bar 27 is fixed on the bottom inner wall of the liquid storage chamber 11, and its height is set to 3-5 cm. It is intended to make the sediment accumulate at the bottom of the liquid storage chamber 11 by physical isolation. The location of the sedimentation isolation bar 27 ensures that impurities can be discharged through the sewage pipe 14, and also prevents the water pump 12 from pumping impurities.

[0069] In another embodiment of the present invention, a plurality of track plates 3 located on the same side support plate 2 are rotatably mounted with axles 28 at their bottoms, and a plurality of axles 28 are fixedly sleeved with removal power wheels 29, and the outer edges of the plurality of removal power wheels 29 are respectively in contact with the side edges of the corresponding hydroponic troughs 4, and are used to remove the hydroponic troughs 4 with forage grass when rotating, and a power clutch mechanism for driving the plurality of removal power wheels 29 to rotate is provided on the corresponding side support plate 2.

[0070] In this embodiment, axles 28 and removal power wheels 29 are installed at the bottom of multiple track plates 3 located on the same side support plate 2. These removal power wheels 29 are connected to the track plate 3 through the axles 28, and their outer edges are in close contact with the side of the hydroponic tank 4. When the hydroponic tank 4 is taken out, the rotation of the removal power wheel 29 can drive the hydroponic tank 4 to slide on the track plate 3, thereby realizing the convenient removal of the hydroponic tank 4 with forage grass, reducing people's labor burden. At the same time, the side support plate 2 is also equipped with a power clutch mechanism, which is used to drive the removal power wheel 29 at the hydroponic tank 4 where it is necessary to take out to rotate, and avoid the rotation of other removal power wheels 29 at the hydroponic tank 4 where it is not necessary to take out. Automatically push out to achieve automatic cutting of the roots, and people only need to take off the forage grass. When the hydroponic tank 4 is sent into the hydroponic tank 4, the removal power wheel 29 has no power input to ensure free rotation.

[0071] In another embodiment of the present invention, the power clutch mechanism includes an L-shaped support plate 30, a retracting power cylinder 31, an electric telescopic rod 32, an assembly shaft plate 33, a power transmission shaft 34, a guide hole 35, a guide pin 36, a friction disc 1 37, a power connection shaft 38, a friction disc 2 39, a pair of bevel gears 1 40 and a drive motor 41, the L-shaped support plate 30 is fixedly mounted on the outer side of the side support plate 2 corresponding to the removal power wheel 29, the retracting power cylinder 31 is rotatably mounted on the L-shaped support plate 30, and the electric telescopic rod 32 is fixedly mounted on the side support plate 2 The assembly shaft plate 33 is slidably arranged in the L-shaped support plate 30 and is fixedly connected to the output rod of the electric telescopic rod 32. The assembly shaft plate 33 is located between the side support plate 2 and the retracting power cylinder 31. The power transmission shaft 34 is rotatably mounted on the assembly shaft plate 33. One end of the power transmission shaft 34 is slidably inserted into the retracting power cylinder 31. The guide hole 35 is provided on the retracting power cylinder 31. The guide pin 36 is slidably mounted in the guide hole 35 and is fixedly connected to the power transmission shaft 34, so that the retracting power cylinder 31 and the power transmission shaft 34 can be retracted along the guide hole 35. The hole 35 and the guide pin 36 are guided to extend and rotate synchronously. The friction disc 1 37 is fixedly mounted on the end of the power transmission shaft 34 outside the contraction power cylinder 31. The corresponding side support plate 2 is rotatably mounted with a power connection shaft 38. The power connection shaft 38 is coaxially arranged with the power transmission shaft 34. The friction disc 2 39 is fixedly mounted on the end of the power connection shaft 38 located at the friction disc 1 37. The friction disc 2 39 and the friction disc 1 37 use an electric telescopic rod 32 to control the displacement of the assembly shaft plate 33 and the power transmission shaft 34 to achieve engagement and separation. A pair of bevel gears 40 are fixedly mounted on the wheel axle 28 and the power connection shaft 38 respectively, and the pair of bevel gears 40 are meshed with each other. The drive motor 41 is fixedly mounted on the outer side of the corresponding side support plate 2. The output shaft of the drive motor 41 and the contraction power cylinders 31 of the multiple power clutch mechanisms are fixedly mounted with a synchronous sprocket 42. The multiple synchronous sprockets 42 are mounted with the same synchronous chain 43. Multiple tensioning wheels 44 are rotatably mounted on the corresponding side support plate 2, and the multiple tensioning wheels 44 are all used to tighten the synchronous chain 43.

[0072] In this embodiment, the wheel shaft 28 and the extraction power wheel 29 realize precise control of the extraction power wheel 29 through the power clutch mechanism. When the hydroponic tank 4 with forage grass needs to be removed, the power clutch mechanism drives the corresponding extraction power wheel 29 to rotate, driving the hydroponic tank 4 to slide on the track plate 3, so as to realize convenient removal. At the same time, the design of the power clutch mechanism also ensures that only the extraction power wheel 29 corresponding to the hydroponic tank 4 that needs to be removed will rotate, avoiding unnecessary energy consumption and wear.

[0073] During the forage planting process, when it is necessary to remove one or some hydroponic tanks 4, the operator first starts the drive motor 41. The drive motor 41 drives the retracting power cylinders 31 of all power clutch mechanisms to rotate synchronously through the synchronous sprocket 42 and the synchronous chain 43. However, due to the control of the electric telescopic rod 32, only the assembly shaft plate 33 and the power transmission shaft 34 of the power clutch mechanism corresponding to the hydroponic tank 4 that needs to be removed will be pushed out, so that the friction disk 1 37 is engaged with the friction disk 2 39. At this time, the rotation of the retracting power cylinder 31 is through the power transmission shaft 34, the bevel gear 1 40 and other transmission parts, and finally drives the corresponding wheel axle 28 and the removal power wheel 29 to rotate. The outer edge of the removal power wheel 29 is in close contact with the side of the hydroponic tank 4, and when rotating, it drives the hydroponic tank 4 to slide on the track plate 3, so as to achieve convenient removal. After removal, the operator can separate the friction disk 1 37 from the friction disk 2 39 by turning off the drive motor 41 or adjusting the electric telescopic rod 32, and stop the rotation of the removal power wheel 29.

[0074] Through the design of the power clutch mechanism, precise control of taking out the power wheel 29 is achieved, and the operator only needs to perform simple operations to conveniently take out the hydroponic tank 4 with forage grass, which greatly improves the convenience and efficiency of the operation.

[0075] The design of the power clutch mechanism also ensures that only the extraction power wheel 29 corresponding to the hydroponic tank 4 that needs to be removed will rotate, avoiding unnecessary energy consumption and wear and tear, and extending the service life of the equipment.

[0076] In another embodiment of the present invention, a reciprocating shaft 45 is rotatably mounted on the top inner wall of the reflux chamber 21, and a compression cam 46 is fixedly mounted on one end of the reciprocating shaft 45 located in the reflux chamber 21, and the outer edge of the compression cam 46 contacts the side of the compression net 25 away from the filter material 26, and is used to cooperate with the reset telescopic rod 24 to realize the reciprocating sliding of the compression net 25 to compress the filter material 26, and a driving shaft 47 is rotatably mounted on the side support plate 2 corresponding to the reciprocating shaft 45 and the power clutch mechanism, and a bevel gear 2 48 is fixedly mounted on the driving shaft 47 and the reciprocating shaft 45, and the two bevel gears 2 48 are meshed with each other, and a driven sprocket 49 is also fixedly mounted on the driving shaft 47, and the driven sprocket 49 is transmission connected to the synchronous chain 43.

[0077] In this embodiment, a reciprocating shaft 45 and a compression cam 46 are installed on the top inner wall of the reflux chamber 21. The rotation of the compression cam 46 is realized through the linkage of the power clutch mechanism and the drive shaft 47, thereby driving the compression net 25 to slide and compress the filter material 26 in a reciprocating manner in cooperation with the resetting telescopic rod 24. This design is intended to improve the filtration efficiency and service life of the filter material 26, while ensuring the smooth flow of the nutrient solution in the reflux chamber 21.

[0078] During the forage planting process, when the nutrient solution flows through the reflux chamber 21, the impurities and particulate matter therein will be intercepted by the filter material 26. As time goes by, the impurities on the filter material 26 will gradually increase, affecting its filtering efficiency. At this time, the power clutch mechanism drives the drive shaft 47 to rotate. Since the drive shaft 47 and the reciprocating shaft 45 are both fixedly sleeved with meshing bevel gears 48, the rotation of the drive shaft 47 will drive the reciprocating shaft 45 to rotate synchronously. The rotating reciprocating shaft 45 drives the compression cam 46 thereon to rotate, and the outer edge of the compression cam 46 contacts the side of the compression net 25 away from the filter material 26, thereby pushing the compression net 25 to reciprocate and slide and compress the filter material 26 with the cooperation of the reset telescopic rod 24. In this process, the flow of the nutrient solution inside the filter material 26 is promoted, and the retention and blockage of the nutrient solution are prevented.

[0079] Through the design of the reciprocating shaft 45 and the compression cam 46, reciprocating sliding compression of the filter material 26 is achieved, thereby effectively removing impurities and particulate matter on the filter material 26 and improving its filtering efficiency.

[0080] The reciprocating sliding compression also promotes the flow of the nutrient solution inside the filter material 26 , preventing the nutrient solution from being retained and blocked, thereby extending the service life of the filter material 26 .

[0081] In summary, compared with the relevant technology, the present device can ensure that the roots passing through the through hole 5 are cut off during the harvesting process through the detachable hydroponic trough 4 and the root cutting knife 7 outside the trough, which is convenient for the subsequent manual removal of the whole forage grass and realizes efficient harvesting of forage grass. Compared with the traditional pulling removal method, this method greatly reduces the amount of manual labor and improves the harvesting efficiency.
