Description

Technical Field

[0001] The invention relates to the technical field of grass seed seedling cultivation, in particular to a specific environmental factor simulation device for grass seed seedling cultivation. Background Art

[0002] In the field of grass seedling cultivation, providing a suitable growth environment is crucial to ensure the healthy development of seedlings. Traditional seedling cultivation methods rely on natural conditions or relatively simple control methods, which are difficult to accurately control various environmental factors that affect grass seed growth, such as temperature, humidity, light and soil conditions. Especially for grass seeds sown at equal intervals, since the seed distribution is relatively uniform and fixed, higher requirements are placed on soil permeability and moisture management.

[0003] Watering is an essential operation during the germination and initial growth stages of grass seeds. However, frequent watering can easily lead to compaction of the surface soil, which not only hinders the delivery of oxygen to the roots, but also affects the effective penetration of water, thereby inhibiting the normal growth of grass seeds. In order to solve this problem, some improvement measures have been proposed and applied in practice, such as using loosening tools to manually loosen the surface soil or using sprayers to reduce water flow to avoid direct impact on the soil surface. However, these methods either increase labor costs or have limited effects and cannot fundamentally solve the problem of soil compaction.

[0004] In order to solve the above problems, we provide a specific environmental factor simulation device for grass seed seedling cultivation. This seedling simulation device can automatically loosen the surface soil appropriately after each watering, which can effectively improve soil permeability and prevent soil compaction caused by watering, thereby creating more favorable growth conditions for grass seeds. In addition, this device can also adjust working parameters according to different seedling cultivation needs to adapt to the specific requirements of different growth stages, significantly improving seedling cultivation efficiency and quality. Summary of the invention

[0005] In order to overcome the shortcomings of static seedling beds that cause the soil surface to be compressed for a long time after frequent watering, resulting in a decrease in soil permeability, the soil structure tending to become compacted, and affecting root development and nutrient absorption, the present invention provides a specific environmental factor simulation device for grass seed seedling cultivation.

DETAILED DESCRIPTION

[0034] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0035] Embodiment 1: A specific environmental factor simulation device for grass seed cultivation, such as Figure 1-Figure 10 As shown, it includes a simulation box 1, a box door 2, a seedling tray 3, a ventilation fan 4, a cross bar 5, an atomizing sprayer 6, a water storage tank 7, a connecting pipe 8, a water pump 81, a screw 9, a driving motor 10, a connecting block 11, a first slider 12, a sliding rod 13, a loosening frame 14, a driving component and an adjusting component. The front side of the simulation box 1 is rotatably connected with two box doors 2 that are symmetrical on the left and right. The lower part of the simulation box 1 is fixedly connected with a seedling tray 3. The seedling tray 3 is provided with equidistantly distributed seedling cavities, and each seedling cavity is provided with a drainage groove on the lower side. The left side of the simulation box 1 is connected to the ventilation fan 4, and the right side of the simulation box 1 is provided with a ventilator with an interception net. The left and right parts of the simulation box 1 are fixedly connected with a cross bar 5, and an atomizing sprayer 6 is slidably connected between the left and right cross bars 5. The lower part of the rear side of the simulation box 1 is fixedly connected with a water storage tank 7, and the left and right parts of the rear side of the atomizing sprayer 6 They are all connected with a connecting pipe 8, and the left and right parts of the water tank 7 are fixedly connected with a water pump 81. The tail end of the connecting pipe 8 passes through the rear side of the simulation box 1, and then passes into the water tank 7 to be connected with the adjacent water pump 81. A screw rod 9 is rotatably connected to the middle part of the simulation box 1, and a driving motor 10 is fixedly connected to the middle part of the rear side of the simulation box 1. The output shaft of the driving motor 10 is fixedly connected to the screw rod 9, and a connecting block 11 is threadedly connected to the screw rod 9. The connecting block 11 is fixedly connected to the atomizing sprayer 6. The seedling tray 3 is slidably connected with an equidistantly distributed first sliding block 12, and a sliding rod 13 is slidably connected in the first sliding block 12. A loosening frame 14 is rotatably connected between the upper parts of the three corresponding sliding rods 13 in the transverse direction. The seedling tray 3 is provided with a driving component for driving the loosening frame 14 to move forward and backward, and the seedling tray 3 is provided with an adjusting component for adjusting the height of the loosening frame 14.

[0036] When using the device, the staff will sow the grass seeds in the seedling cavity of the seedling tray 3 at equal intervals by spot sowing. During the seedling period, the ventilation fan 4 operates to ventilate the simulation box 1, thereby adjusting the temperature and humidity. The driving motor 10 drives the screw rod 9 to rotate, which can drive the connecting block 11 to move forward and backward. The forward and backward movement of the connecting block 11 drives the atomizing sprinkler 6 to slide forward and backward to water the seedling tray 3. When the atomizing sprinkler 6 slides forward and backward for watering, the water pump 81 and the connecting pipe 8 can supply the water in the water tank 7 into the atomizing sprinkler 6, and the atomizing sprinkler 6 moves forward for spraying and watering. After the watering is completed, the atomizing sprinkler 6 moves backward and resets, and the driving component controls the loosening frame 14 to move forward and backward to loosen the surface soil appropriately, which can effectively improve the soil permeability and prevent the soil from being compacted due to watering, thereby creating more favorable growth conditions for the grass seeds. The adjusting component can adjust the height of the loosening frame 14 according to the growth of the grass seedlings to prevent the loosening frame 14 from breaking the grass seedlings.

[0037] like Figure 7 , Figure 8 and Fig. 9 As shown, the driving assembly includes a guide rod 15, a second slider 16, a first spring 161, a contact block 17, a second spring 18 and a first connecting frame 19. The guide rod 15 is fixedly connected to the left upper portion of the seedling tray 3. The second slider 16 is slidably connected to the guide rod 15. The first spring 161 is connected between the second slider 16 and the guide rod 15. The contact block 17 is slidably connected to the second slider 16. The front and rear sides of the upper portion of the contact block 17 are both inclined. The atomizing sprayer 6 moves forward and backward and is pressed and matched with the contact block 17. Two second springs 18 are connected between the contact block 17 and the second slider 16. The first connecting frame 19 is slidably connected to the right side of the second slider 16. The left portion of the loosening frame 14 is rotatably connected to the first connecting frame 19.

[0038] When the atomizing sprayer 6 moves forward to water, since the loosening frame 14 cannot move forward, when the atomizing sprayer 6 moves forward to contact with the contact block 17, the atomizing sprayer 6 will squeeze the contact block 17 to slide downward, and the second spring 18 will be deformed. When the atomizing sprayer 6 moves forward to be independent of the contact block 17, under the action of the second spring 18 resetting, the contact block 17 will slide upward and reset. When the atomizing sprayer 6 completes watering and slides backward to reset, the atomizing sprayer 6 will contact the contact block 17 again. At this time, the atomizing sprayer 6 continues to move backward and will push the contact block 17 to move backward. The backward movement of the contact block 17 drives the second slider 16 to slide backward, and the first spring 18 moves backward. 161 is deformed, the second slider 16 slides backward and drives the first connecting frame 19 to move backward, the first connecting frame 19 moves backward and drives the loosening frame 14 to move backward, when the loosening frame 14 moves backward to the limit distance, the atomizing sprayer 6 continues to move backward and will squeeze the contact block 17 to slide downward again, and then separate from the contact block 17, at this time, under the action of the first spring 161 resetting, the second slider 16 will drive the loosening frame 14 to move forward and reset through the first connecting frame 19, the loosening frame 14 can loosen the topsoil appropriately when moving forward and backward, which can effectively improve the soil permeability and prevent the soil compaction caused by watering, thereby creating more favorable growth conditions for grass seeds.

[0039] like Fig.10 and Fig.11 As shown, the adjustment assembly includes a vertical rod 20, a horizontal plate 21, a screw rod 22 and a sliding plate 23. Two vertical rods 20 symmetrically arranged front and rear are fixedly connected to the upper right portion of the simulation box 1. A horizontal plate 21 is slidably connected between the two vertical rods 20. A screw rod 22 is rotatably connected to the right front portion of the upper side of the simulation box 1. The screw rod 22 is connected to the horizontal plate 21 through threads. A sliding plate 23 is rotatably connected to the right portion of the loosening frame 14. The sliding plate 23 is slidably connected to the horizontal plate 21.

[0040] In the initial state, the loosening depth of the soil loosening frame 14 is the deepest, and the soil can be turned over over a large range so that the roots of the grass seeds can penetrate the soil and spread. As the grass seedlings grow, the staff rotates the screw 22 according to the growth of the grass seedlings, thereby driving the cross plate 21 to slide upward. The upward sliding of the cross plate 21 drives the sliding plate 23 to move upward, and the upward movement of the sliding plate 23 drives the loosening frame 14 to move upward. The loosening frame 14 moves and then rises. At this time, the loosening frame 14 will not damage the grass seedlings when moving back and forth, and will also reduce the depth of loosening the soil to avoid damaging the roots of the grass seedlings.

[0041] Embodiment 2: Based on embodiment 1, Fig.11 and Fig.12As shown, it also includes an extrusion assembly for controlling the loosening frame 14 to swing forward and backward, and the extrusion assembly includes a torsion spring 24, a contact plate 25, a mounting rod 26, a mounting plate 27 and an extrusion block 28. A torsion spring 24 is connected between the sliding plate 23 and the loosening frame 14, and a contact plate 25 is fixedly connected to the upper right side of the loosening frame 14. Three groups of equidistantly distributed mounting rods 26 are fixedly connected to the cross plate 21, and a mounting plate 27 is fixedly connected between two mounting rods 26 in each group. The mounting plate 27 is located above the contact plate 25, and equidistantly distributed extrusion blocks 28 are fixedly connected to the lower side of the mounting plate 27. The contact plate 25 moves forward and backward to be extruded and matched with the extrusion block 28.

[0042] When using this device, the loosening frame 14 moves forward and backward and drives the contact plate 25 to move forward and backward. When the contact plate 25 moves forward and backward until it contacts the extrusion block 28, the contact plate 25 continues to move forward or backward and is squeezed by the extrusion block 28 to rotate. The rotation of the contact plate 25 drives the loosening frame 14 to rotate, and the torsion spring 24 is deformed. When the contact plate 25 moves forward and backward and separates from the extrusion block 28, under the action of the torsion spring 24 resetting, the loosening frame 14 drives the contact plate 25 to reverse and reset. When the contact plate 25 moves forward and backward and contacts the next extrusion block 28, repeating the above action can make the loosening frame 14 swing back and forth while moving forward and backward, thereby improving the loosening effect.

[0043] like Fig.13 and Fig.14 As shown, it also includes a seedling removal component for pushing out the cultivated grass seedlings, and the seedling removal component includes a filter plate 29, a connecting column 30, a second connecting frame 31, an electric push rod 32 and a fixed plate 33. A filter plate 29 is slidably connected in each seedling cavity of the seedling tray 3, and a connecting column 30 is connected between two laterally adjacent filter plates 29. The second connecting frame 31 is fixedly connected between the three filter plates 29 on the far right, and an electric push rod 32 is fixedly connected to the right part of the simulation box 1. The telescopic end of the electric push rod 32 is fixedly connected to the fixed plate 33, and the fixed plate 33 is fixedly connected to the second connecting frame 31.

[0044] When the grass seedlings are cultivated, the staff controls the electric push rod 32 to extend, and the extension of the electric push rod 32 drives the fixed plate 33 to move upward, and the upward movement of the fixed plate 33 drives the second connecting frame 31 to move upward, and the upward movement of the second connecting frame 31 drives the three filter plates 29 on the far right to move upward. Under the action of the connecting column 30, the other filter plates 29 will also move upward. When the filter plate 29 moves upward, the grass seedlings in each seedling cavity of the seedling tray 3 can be pushed upward together with the soil, so that the staff can transplant them. After the grass seedlings and soil are taken out, the staff controls the electric push rod 32 to shorten, and the shortening of the electric push rod 32 drives the fixed plate 33, the second connecting frame 31, the filter plate 29 and the connecting column 30 to move downward and reset.

[0045] like Figure 1 and Fig.15 As shown, it also includes a collection component for collecting excess water, the collection component includes a wastewater collection box 34 and an outlet pipe 35, the wastewater collection box 34 is fixedly connected to the lower side of the seedling tray 3, the left side of the wastewater collection box 34 is connected to the outlet pipe 35, and the outlet pipe 35 extends out of the simulation box 1.

[0046] When the device is used, after each watering, the excess water in the seedling tray 3 will pass through the filter plate 29 and be discharged from the drainage groove on the lower side to avoid water accumulation and root rot. The excess water is discharged into the wastewater collection box 34, and the staff can discharge the water through the outlet pipe 35 for utilization.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
