Description

Technical Field

[0001] The present invention relates to the technical field of seed cultivation, and particularly relates to an adjustable multi-functional agricultural seed cultivation device. Background Art

[0002] In agricultural planting, in order to improve yield and quality, the cultivation of agricultural seeds is particularly important. It can not only increase the yield and quality of crops, but also help maintain biodiversity and protect the ecological environment, and promote the development of agricultural modernization.

[0003] Appropriate light can stimulate the physiological activity of seeds, accelerate the conversion and utilization of internal nutrients, and thus promote the germination of seeds and the photosynthesis of seedlings. Most existing seed cultivation devices only set light sources on the top of the cultivation box, such as incandescent lamps. The light of incandescent lamps is relatively scattered, which not only easily causes the problem of uneven light, but also the scattered light source easily makes more light dissipate into non-target areas, reducing the utilization rate of light energy. Based on this, an adjustable multi-functional agricultural seed cultivation device is proposed. Summary of the Invention

[0004] The present invention provides an adjustable multi-functional agricultural seed cultivation device to solve the problems in the above technical background that most existing seed cultivation devices only set light sources on the top of the cultivation box, such as incandescent lamps. The light of incandescent lamps is relatively scattered, which not only easily causes the problem of uneven light, but also the scattered light source easily makes more light dissipate into non-target areas, reducing the utilization rate of light energy.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions: An adjustable multi-functional agricultural seed cultivation device includes a cultivation box. An installation plate is fixedly provided above the cultivation box. A plurality of supplementary light lamps are evenly arranged at the bottom of the installation plate.

A rotating shaft is rotatably connected in the adjusting grooves. Both ends of the rotating shaft penetrate through the installation plate and are fixedly connected to the reflective plates. An angle adjusting mechanism for the rotation of the rotating shaft is provided on the top of the cultivation box. A partition is fixedly provided below the cultivation box. A cultivation tray is provided on the top of the partition. Filter holes are formed at the bottoms of both the partition and the cultivation tray. A spraying assembly is provided above the cultivation tray. A moving mechanism for the movement of the spraying assembly is provided on the inner walls of both sides of the cultivation box.

[0006] Preferably, the angle adjustment mechanism includes a vertical rod rotatably connected to the top of the cultivation box through a bearing. The bottom of the vertical rod extends through and is fixedly connected to a first bevel gear in the adjustment groove. The first bevel gear is meshed with a second bevel gear, and the second bevel gear is fixedly sleeved on the rotating shaft.

[0007] Preferably, a device box is fixedly arranged on the top of the cultivation box. A rotating motor is fixedly arranged on one side of the device box. The output shaft of the rotating motor is fixedly connected to a cross bar. A plurality of third bevel gears are fixedly sleeved on the cross bar. The top of the vertical rod extends through and is fixedly sleeved with a fourth bevel gear in the device box. The fourth bevel gear is meshed with the third bevel gears.

[0008] Preferably, the directions of adjacent third bevel gears are arranged in opposite directions.

[0009] Preferably, the lifting mechanism includes a lead screw rotatably connected to the inner wall of the top of the cultivation box. A threaded barrel is threadedly connected to the lead screw. A through groove for the threaded barrel to pass through is formed on the mounting plate. The bottom of the threaded barrel extends through the through groove and is fixedly connected to the supplementary light.

[0010] Preferably, a first gear is fixedly sleeved above the lead screw. A second gear is fixedly sleeved on the vertical rod on the same side of the lead screw. The second gear is meshed with the first gear, and the diameter of the second gear is larger than that of the first gear.

[0011] Preferably, limiting grooves are formed on the inner walls on both sides of the through groove. Limiting blocks are fixedly arranged on the outer walls on both sides of the threaded barrel. The limiting blocks are slidably connected in the limiting grooves.

[0012] Preferably, the moving mechanism includes fixed seats fixedly arranged inside both sides of the cultivation box. Grooves are formed on the inner walls on opposite sides of the fixed seats. A threaded rod is rotatably connected in the grooves. A moving block is threadedly connected to the threaded rod. A cross plate is fixedly arranged between the two moving blocks. The spraying assembly is fixedly arranged at the bottom of the cross plate.

[0013] Preferably, one end of the threaded rod extends through the cultivation box and is fixedly sleeved with a transmission wheel. The two transmission wheels are connected by a transmission belt. A driving motor is fixedly arranged on the outer wall of one side of the cultivation box. One of the threaded rods is fixedly connected to the output shaft of the driving motor.

[0014] Preferably, the spraying assembly includes a water spraying pipe fixedly arranged at the bottom of the cross plate. A plurality of nozzles are evenly fixedly arranged at the bottom of the water spraying pipe. A water pump is fixedly arranged on the outer wall of one side of the cultivation box. The water outlet end of the water pump is fixedly connected to a hose. The hose extends through and is fixedly connected to one side of the water spraying pipe.

[0015] Beneficial effects of the adjustable multi-functional agricultural seed cultivation device of the present invention:

[0016] (1) In the present invention, the driving motor drives the cross bar and the third bevel gear to rotate. The third bevel gear meshes with the fourth bevel gear to rotate. The fourth bevel gear drives the vertical rod and the first bevel gear at its bottom to rotate. The first bevel gear meshes with the second bevel gear to rotate. The second bevel gear drives the rotating shaft to rotate. The adjacent third bevel gears are in opposite directions, so that the rotating shafts on both sides of the supplementary light lamp drive the reflecting plates to rotate in opposite directions, causing the angle between the two reflecting plates to open or close, adjusting the angle between the two reflecting plates, converging the light emitted by the supplementary light lamp and adjusting the width of the converged light when irradiating downward, and avoiding the divergence of light from reducing the utilization rate of light energy.

[0017] (2) While the vertical column rotates in the present invention, the second gear on the vertical column meshes with the first gear to rotate. The first gear drives the lead screw to rotate, causing the threaded cylinder threadedly connected to the lead screw to move up and down. Furthermore, the supplementary light lamp at the bottom of the threaded cylinder moves up and down. While adjusting the angles of the two reflecting plates, the height of the supplementary light lamp is synchronously adjusted. This can not only quickly converge the light irradiated by the supplementary light lamp to an appropriate width range, but also make the height of the supplementary light lamp adapt to the angle of the reflecting plate, improving the effect of the reflecting plate in converging the light.

[0018] (3) In the present invention, the driving motor drives the threaded rod on one side to rotate. Under the action of the transmission wheel and the transmission belt, the threaded rods on both sides rotate synchronously, causing the moving block on the threaded rod to drive the cross plate and the water spray pipe at its bottom to move above the cultivation tray, improving the uniformity of spraying the seeds or seedlings in the cultivation tray by the nozzles below the water spray pipe. Moreover, when watering is not required, the water spray pipe is moved to one side of the cultivation box to avoid it blocking the light irradiated in opposite directions and affecting the lighting effect.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0033] Such as Figure 1-7As shown in the figure, an adjustable multi-functional agricultural seed cultivation device includes a cultivation box 1. Ventilation holes are provided on both side walls of the cultivation box 1. An installation plate 2 is fixedly provided above the cultivation box 1. A plurality of supplementary light lamps 3 are evenly arranged at the bottom of the installation plate 2. A lifting mechanism for the up and down movement of the supplementary light lamps 3 is provided on the installation plate 2. Reflector plates 6 are rotatably connected to both sides of the supplementary light lamps 3. Adjustment grooves 4 are provided on the installation plate 2 on both sides of the supplementary light lamps 3. A rotating shaft 5 is rotatably connected in the adjustment grooves 4. Both ends of the rotating shaft 5 penetrate through the installation plate 2 and are fixedly connected to the reflector plates 6. An angle adjustment mechanism for the rotation of the rotating shaft 5 is provided on the top of the cultivation box 1. A partition plate 7 is fixedly provided below the cultivation box 1. A cultivation tray 8 is provided on the top of the partition plate 7. Filter holes are provided at the bottoms of both the partition plate 7 and the cultivation tray 8. A spraying assembly is provided above the cultivation tray 8. Moving mechanisms for the movement of the spraying assembly are provided on the inner walls of both sides of the cultivation box 1.

[0034] The angle adjustment mechanism includes a vertical rod 9 rotatably connected to the top of the cultivation box 1 through a bearing. The bottom of the vertical rod 9 penetrates and extends into the adjustment groove 4 and is fixedly connected to a first bevel gear 10. The first bevel gear 10 is meshed and connected with a second bevel gear 11. The second bevel gear 11 is fixedly sleeved on the rotating shaft 5.

[0035] By rotating the vertical column 9 to drive the first bevel gear 10 to rotate, the first bevel gear 10 meshes with the second bevel gear 11 to rotate, the second bevel gear 11 drives the rotating shaft 5 to rotate, and then drives the reflector plate 6 fixedly connected to the rotating shaft 5 to rotate, so as to achieve the purpose of adjusting the angle of the reflector plate 6. By adjusting the angle of the reflector plate 6, the light of the supplementary light lamp 3 is gathered to different degrees.

[0036] A device box 12 is fixedly provided on the top of the cultivation box 1. A rotating motor 13 is fixedly provided on one side of the device box 12. The output shaft of the rotating motor 13 is fixedly connected with a cross bar 14. A plurality of third bevel gears 15 are fixedly sleeved on the cross bar 14. The top of the vertical rod 9 penetrates and extends into the device box 12 and is fixedly sleeved with a fourth bevel gear 16. The fourth bevel gear 16 is meshed and connected with the third bevel gear 15.

[0037] By driving the cross bar 14 and the plurality of third bevel gears 15 on the cross bar by the driving motor 13 to rotate, the third bevel gears 15 mesh with the plurality of fourth bevel gears 16 to rotate synchronously. The fourth bevel gears 16 drive the plurality of vertical rods 9 and the first bevel gears 10 at their bottoms to rotate. The first bevel gear 10 meshes with the second bevel gear 11 to rotate, so that the second bevel gear 11 drives the plurality of rotating shafts 5 and the reflector plates 6 to rotate synchronously, achieving the effect of synchronously adjusting the angles of all the reflector plates 6.

[0038] They are arranged in opposite directions adjacent to the third bevel gear 15, so that the rotation directions of the two side vertical rods 9 are opposite, so that the rotation directions of the adjacent first bevel gears 10 meshing with the second bevel gears 11 are opposite, so that the rotating shafts 5 on both sides of the supplementary light 3 drive the reflecting plates 6 to rotate in opposite directions, so that the effect of opening or closing is achieved between the two side reflecting plates 6, the angle between the two side reflecting plates 6 is adjusted, the light emitted by the supplementary light 3 is gathered, and the width of the gathered light when irradiating downward is adjusted, so that the gathered light can fully irradiate the seeds or seedlings in the cultivation tray, and the divergence of the light is avoided to reduce the utilization rate of the light energy.

[0039] The lifting mechanism includes a lead screw 17 rotatably connected to the inner wall of the top of the cultivation box 1. A threaded cylinder 18 is threadedly connected to the lead screw 17. A through groove 19 for the threaded cylinder 18 to pass through is formed in the mounting plate 2. The bottom of the threaded cylinder 18 penetrates through the through groove 19 and is fixedly connected to the supplementary light 3. Both the through groove 19 and the threaded cylinder 18 are rectangularly arranged.

[0040] A first gear 20 is fixedly sleeved above the lead screw 17. A second gear 21 is fixedly sleeved on the vertical rod 9 on the same side of the lead screw 17. The second gear 21 is meshed and connected with the first gear 20. The diameter of the second gear 21 is larger than the diameter of the first gear 20.

[0041] While the vertical rod 9 rotates, the second gear 21 meshes with the first gear 20 to rotate, thereby driving the lead screw 17 to rotate. And because the diameter of the second gear 21 is larger than the diameter of the first gear 20, the vertical column 9 can drive the lead screw 17 to rotate sufficiently under the condition of small amplitude rotation, so that the threaded cylinder 18 threadedly connected to the lead screw 17 drives the supplementary light 3 below to move up and down, so as to synchronously adjust the angle of the reflecting plate 6 and the height of the supplementary light 3, so that the light irradiating downward can be quickly gathered to an appropriate width range.

[0042] Limit grooves 22 are formed on the inner walls of both sides of the through groove 19. Limit blocks 23 are fixedly arranged on the outer walls of both sides of the threaded cylinder 18. The limit blocks 23 are slidably connected in the limit grooves 22. The movement track of the threaded cylinder 18 is restricted by the limit blocks 23 and the limit grooves 22, so as to prevent the threaded cylinder 18 from rotating along with the rotation of the lead screw 17, so that the threaded cylinder 18 only moves in the up and down directions.

[0043] The moving mechanism includes fixed seats 24 fixedly arranged inside both sides of the cultivation box 1. Grooves 25 are formed on the inner walls of opposite sides of the fixed seats 24. A threaded rod 26 is rotatably connected in the grooves 25. A moving block 27 is threadedly connected to the threaded rod 26. A cross plate 28 is fixedly arranged between the two moving blocks 27. The spraying assembly is fixedly arranged at the bottom of the cross plate 28.

[0044] When water spraying is required, the rotation of the threaded rod 26 causes the moving block 27 to drive the cross plate 28 to move, so that the spraying assembly at the bottom of the cross plate 28 moves continuously during spraying, improving the uniformity during spraying. When water spraying is not carried out, the cross plate 28 and the spraying assembly at the bottom are moved to one side of the cultivation box 1 to prevent the spraying assembly from affecting the light.

[0045] One end of the threaded rod 26 penetrates through the cultivation box 1 and is fixedly sleeved with a transmission wheel 29. The two transmission wheels 29 are connected by a transmission belt 30 in a transmission manner. A driving motor 31 is fixedly arranged on the outer wall of one side of the cultivation box 1, and one side of the threaded rod 26 is fixedly connected to the output shaft of the driving motor 31.

[0046] The driving motor 31 drives the threaded rod 26 on one side to rotate. Under the action of the transmission wheel 29 and the transmission belt 30, the threaded rods 26 on both sides rotate synchronously, so that the moving block 27 on the threaded rod 26 drives the cross plate 28 to move stably, and further the spraying assembly at the bottom of the cross plate 28 moves stably.

[0047] The spraying assembly includes a water spraying pipe 32 fixedly arranged at the bottom of the cross plate 28. A plurality of nozzles 33 are uniformly fixedly arranged at the bottom of the water spraying pipe 32. A water pump 34 is fixedly arranged on the outer wall of one side of the cultivation box 1. The water outlet end of the water pump 34 is fixedly connected with a hose 35. The hose 35 penetrates and extends into the cultivation box 1 and is fixedly connected to one side of the water spraying pipe 32. When water spraying is required, the water pump 34 pumps water or other nutrient solutions and other liquids into the hose 35, and the water is sprayed downward by the nozzles 33 at the bottom of the water spraying pipe 32.

[0048] A box door is hinged to one side of the cultivation box 1 through a hinge. A placement groove is formed at the top of the partition plate 7. The cultivation tray 8 is clamped in the placement groove, which can not only improve the stability of the cultivation tray 8 on the top of the partition plate 7, but also facilitate the removal of the cultivation tray 8 from the cultivation box 1.

[0049] During use, place the seeds in the cultivation tray 8, and place the cultivation tray 8 in the placement groove on the partition plate 7. When watering is required, pump water from the water source to the water spray pipe 32 through the water pump 34, and spray it downward through the nozzle 33. At the same time, start the drive motor 31 to drive the threaded rod 26 on one side to rotate. Under the action of the transmission wheel 29 and the transmission belt 30, the threaded rods 26 on both sides rotate synchronously, so that the moving block 27 on the threaded rod 26 drives the cross plate 28 and the water spray pipe 32 to move, and evenly spray the cultivation tray 8 below. When spraying is not required, move the water spray pipe 32 to one side of the cultivation box 1 to avoid affecting the illumination of the cultivation tray 8. During illumination, drive the cross bar 14 and the third bevel gear 15 to rotate through the drive motor 13. The third bevel gear 15 meshes with the fourth bevel gear 16 to rotate, and the fourth bevel gear 16 drives the vertical rod 9 and the first bevel gear 10 at its bottom to rotate. The first bevel gear 10 meshes with the second bevel gear 11 to rotate, and the second bevel gear 11 drives the rotating shaft 5 and the reflector 6 to rotate, so that the reflectors 6 on both sides are opened or closed, gather the light emitted by the supplementary light lamp 3, and adjust the width of the gathered light when irradiating downward, so that the gathered light can fully irradiate the seeds or seedlings in the cultivation tray 8, and avoid the divergence of light from reducing the utilization rate of light energy.

[0050] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
