Description

Technical Field

[0001] The invention relates to the technical field of sprout cultivation, in particular to a box changing mechanism in a sprout planting device. Background Art

[0002] When cultivating sprouts, it is generally necessary to first soak the sprout seeds in water, and then plant the soaked sprout seeds to allow the sprout seeds to grow and develop into sprouts. In order to make the sprouts longer, thicker and have a better taste, there is currently a more innovative method, which is to place the sprouts in a cultivation box for cultivation. The upper part of each cultivation box is an opening, and multiple cultivation boxes are stacked up and down, and a cover is provided on the upper opening of the top cultivation box. In this way, the planting space in each cultivation box is isolated from the external atmosphere, and the initial gas in the planting space is atmospheric air. In addition, air vents are provided on each cultivation box, and the exhaust area of ​​the exhaust vents is controlled to control the carbon dioxide content in the planting space in the cultivation box, thereby controlling the release of growth hormone and the synthesis of ethylene in adverse conditions during the growth of the sprouts.

[0003] Ensure that there is more oxygen and less carbon dioxide in the early stage of sprout planting, so that the sprouts can grow roots and sprouts, making the sprouts longer. In the later stage of sprout planting, there is less oxygen and more carbon dioxide, which enhances the growth hormone of the sprouts and promotes the synthesis of large amounts of ethylene in plant adversity, making the sprouts thicker. In this way, the sprouts after planting are longer and thicker.

[0004] However, in actual operation, the exhaust area of ​​the exhaust hole cannot be used to cope with special events (power outages, water outages, air conditioning) during the production process, and the control will not be very precise. This may sometimes cause the carbon dioxide, oxygen and ethylene concentrations in the incubator to get out of control and exceed the current predetermined concentration, which will affect the normal cultivation of sprouts. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a box-changing mechanism in a sprout planting device, which can move the incubation boxes when the concentrations of carbon dioxide, oxygen and ethylene in the incubation boxes are out of control and exceed the current predetermined concentrations, so that the gases in each incubation box can be released, and at the same time, the gases are replaced up and down to solve the temperature difference inside the stacked incubation boxes, so that the gases in each incubation box can be restored to the atmospheric state.

[0006] In order to solve the above technical problems, the present invention provides a box-changing mechanism in a sprout planting device, which includes:

[0007] A first supporting mechanism, the first supporting mechanism being used to lift or release any one of the incubators or the cover;

[0008] A two-axis driving mechanism is used to drive the first supporting mechanism to move horizontally or vertically up and down.

[0009] Preferably, the box changing mechanism is provided with two vertical spaces, which are arranged horizontally at intervals, and both vertical spaces are used for vertically stacking multiple incubators up and down, and the two-axis driving mechanism is used to drive the first support mechanism to move back and forth between the two vertical spaces or to move vertically up and down in any one of the vertical spaces.

[0010] Preferably, the box-changing mechanism further comprises:

[0011] The second supporting mechanism is located directly above one of the vertical spaces and is used to lift or release the cover.

[0012] Preferably, the first supporting mechanism includes a frame body, the frame body is provided with a vertical passage for the incubator to pass through, a first supporting plate is provided on both sides of the vertical passage, and support portions for supporting the first supporting plate upward are provided on both side walls of the incubator and the cover body;

[0013] The frame body is also provided with a power mechanism for driving the two first supporting plates to move in relative directions or in opposite directions.

[0014] After adopting the above device, the present invention has the following advantages compared with the prior art:

[0015] Due to the box-changing mechanism in the sprout planting device of the present invention, when the concentrations of carbon dioxide, oxygen and ethylene in the incubation box are out of control and exceed the current predetermined concentration, each incubation box can be moved by the first supporting mechanism, so that the upper opening of each incubation box is opened once, thereby allowing the gas and heat in each incubation box to be released, so that the gas in each incubation box is restored to the atmosphere, and then the exhaust area of ​​the exhaust hole is adjusted to readjust the concentrations of carbon dioxide, oxygen and ethylene in the planting space of the incubation box to facilitate the planting of sprouts.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The sprout planting method of this embodiment controls the carbon dioxide content in the planting space to be low in the initial stage, at which time the oxygen content in the planting space is high, thereby promoting the root growth and sprouting of the sprout seeds, and also making the sprouts longer; then gradually increasing the carbon dioxide content in the planting space. As carbon dioxide increases, the oxygen content correspondingly decreases, thereby promoting the sprouts to release ethylene, and the ethylene content gradually increases. Ethylene, as an inhibitor of sprout growth, can make the sprouts become thicker, thus making the cultivated sprouts longer and thicker.

[0028] Specifically, when sprouts are planted, the initial gas in the planting space is the atmosphere, and then the planting space is isolated from the external atmosphere, and an adjustable exhaust hole is set. The exhaust hole can be adjusted to allow gas to circulate between the planting space and the external atmosphere. The adjustable exhaust hole can be covered to adjust the ventilation area of ​​the exhaust hole. In this way, the gas ratio in the planting space at different planting stages can be adjusted by controlling the ventilation area of ​​the adjustable exhaust hole. Because sprouts will continue to breathe during planting, during respiration, the sprouts will consume oxygen and produce carbon dioxide. The generated carbon dioxide accumulates in the planting space, which will cause the two gases in the planting space to accumulate. The carbon dioxide content increases and the oxygen content decreases. If the ventilation area of ​​the exhaust hole is adjusted to be larger, the gas in the planting space can be discharged quickly, which can reduce the carbon dioxide content in the planting space and increase the oxygen content in the planting space. This will prompt the sprouts to release growth hormones, thereby making the sprouts longer. If the ventilation area of ​​the exhaust hole is adjusted to be smaller or even the exhaust hole is completely closed, the gas in the planting space cannot be discharged, which will maintain the carbon dioxide content in the planting space at a higher level and the oxygen content at a lower level. This will prompt the sprouts to release ethylene, which can make the sprouts thicker.

[0029] The planting process is divided into the following stages:

[0030] The first stage (germination stage): In this stage, the ventilation area of ​​the regulating vents is large. Preferably, all the regulating vents are generally opened. At this time, the gas ratio in the planting space is basically the same as that in the atmosphere, that is, the carbon dioxide content in the planting space is about 0.03% and the oxygen content is about 21%. The first stage lasts for about 24 hours and promotes the growth of the radicle of the bean seeds.

[0031] The second stage (growth period): During this stage, the ventilation area of ​​the regulating vents is reduced compared to the first stage. Preferably, half of the area of ​​the regulating vents is closed, so that the ventilation area is half of the total area of ​​the regulating vents. During this stage, the carbon dioxide content in the planting space is about 1%, and the oxygen content is about 16%. The second stage lasts for about 24 hours and promotes the growth of the hypocotyl of the bean seeds.

[0032] The third stage (growing period): In this stage, the ventilation area of ​​the regulating vents is reduced compared to the second stage. Preferably, 75% of the area of ​​the regulating vents is closed, so that the ventilation area is 25% of the total area of ​​the regulating vents. In this stage, the carbon dioxide content in the planting space is about 3%, and the oxygen content is about 10%. The bean seeds release ethylene, and the ethylene content is greater than 30ppm. The third stage lasts for about 24 hours, and this stage promotes the elongation of the radicle of the bean seeds.

[0033] The fourth stage (growing height period): the ventilation area of ​​the vent is adjusted to be unchanged or reduced compared to the third stage, the carbon dioxide content in the planting space is increased compared to the third stage, and the ethylene content in the planting space is increased to 100-300ppm. The ventilation area of ​​the vent depends on the requirements for the finished sprouts. If the ventilation area of ​​the vent is adjusted to be larger, the finished sprouts will be more slender, and if the ventilation area of ​​the vent is adjusted to be smaller, the finished sprouts will be more stout. In this embodiment, all the vents are adjusted to be closed in the fourth stage, that is, the ventilation area is 0, the carbon dioxide content is 6-10%, and the oxygen content is about 10%. The fourth stage lasts for about 24 hours. This stage promotes the simultaneous growth of the radicle and hypocotyl of the bean seeds, the intrinsic growth hormone of the bean seeds is fully activated, the oxygen in the planting box will be consumed, and the carbon dioxide produced after the plant respiration fills the planting space. By adjusting and gradually increasing the carbon dioxide content in the planting space and gradually reducing the oxygen content in the planting space, the plant stress response is generated, the auxin of the bean seeds is greatly stimulated, the synthesis of ethylene is promoted, and the enhancement of ethylene promotes the stimulation of auxin.

[0034] The growth hormone of bean seeds is a plant growth hormone that stimulates the vertical development of seed beans (lengthening), while ethylene is the basic factor that promotes the horizontal development of plants (thickening). Reasonable control of growth hormone and ethylene can prompt sprouts to release ethylene, making the sprouts become thicker.

[0035] Depend on Figure 1 、 Figure 2 As shown, in order to carry out the above sprout planting method, this embodiment discloses a sprout planting device, which can plant sprouts according to the above sprout planting method. The sprout planting device includes a cultivation box 10, a regulator, a driving mechanism and a detection mechanism.

[0036] The incubator 10 is used to place sprout seeds. The incubator 10 is provided with at least one regulating exhaust hole 11 for connecting the interior of the incubator with the external atmosphere. When there are multiple regulating exhaust holes 11, when adjusting the ventilation area, if the ventilation area is to be half of the total area of ​​the regulating exhaust holes, each regulating exhaust hole 11 can be closed halfway or half of the regulating exhaust holes 11 can be completely closed.

[0037] There are multiple incubators 10, which are stacked up and down. The top of each incubator 10 is open. When the upper incubator 10 is stacked on the lower incubator 10, the upper incubator 10 can cover the opening of the lower incubator 10, and a cover is provided on the opening of the top incubator 10.

[0038] The regulator includes an adjustment plate 20, which is movably arranged on the incubator 10. When the adjustment plate 20 moves, the adjustment exhaust hole 11 can be fully opened, partially closed or fully closed, so that the total ventilation area of ​​the adjustment exhaust hole 11 can be adjusted by moving the adjustment plate 20.

[0039] There are multiple adjustment plates 20 , and the adjustment plates 20 are arranged in a one-to-one correspondence with the incubators 10 . Each adjustment plate 20 is used to adjust the total ventilation area of ​​the adjustment exhaust holes 11 on the corresponding incubator 10 .

[0040] The driving mechanism is used to drive the adjustment plate 20 to move. The driving mechanism includes a first mounting rod 30, a second mounting rod 50 and multiple electric push rods 40. Multiple adjustment plates 20 are fixedly set on the first mounting rod 30. Multiple adjustment plates 20 are parallel to each other and arranged at intervals up and down. Multiple electric push rods 40 are installed on the second mounting rod 50. The output shafts of multiple electric push rods 40 are connected to the first mounting rod 30. Multiple electric push rods 40 move synchronously, so that the electric push rods 40 can push the first mounting rod 30 to move horizontally. When the first mounting rod 30 moves, it drives multiple adjustment plates 20 to move synchronously, so as to synchronously adjust the ventilation area of ​​the adjustment exhaust holes 11 on each incubator 10 through the movement of the adjustment plates 20.

[0041] The detection mechanism is used to detect the concentrations of carbon dioxide and ethylene in the incubator 10. The detection mechanism sends the detection information to the controller, and the controller controls the operation of the electric push rod 40 according to the detection information and preset control logic.

[0042] Depend on Figure 3 、 Figure 4 、 Figure 5 As shown, there are multiple adjustment exhaust holes 11 on the incubator 10, and the adjustment plate 20 is provided with multiple openings 21. The openings 21 are arranged in a one-to-one correspondence with the adjustment exhaust holes 11. The area of ​​the openings 21 is slightly larger than the area of ​​the adjustment exhaust holes 11. When the openings 21 are completely staggered with the corresponding adjustment exhaust holes 11, the adjustment plate 20 completely closes the adjustment exhaust holes 11. When the openings 21 are completely or partially overlapped with the corresponding adjustment exhaust holes 11, the overlapping area is the ventilation area of ​​the adjustment exhaust holes 11.

[0043] A chute 12 is provided on the side wall of the incubator 10, and the regulating exhaust holes 11 are all provided in the chute 12 and are spaced apart along the length direction of the chute 12. The adjusting plate 20 is slidably provided in the chute 12. In this way, the ventilation area of ​​the regulating exhaust holes 11 can be controlled by driving the adjusting plate 20 to slide in the chute 12. The chute 12 can guide the sliding of the adjusting plate 20.

[0044] Depend on Figure 1 、 Figure 6As shown, the upper part of the incubator 10 is open, and multiple incubators 10 are stacked vertically. A cover is provided on the opening of the top incubator 10, and the cover is also a box 300. The size and external shape of the box 300 are exactly the same as those of the incubator 10. The bottom surface 320 of the box 300 is a complete flat plate, so that when the box 300 covers the opening at the top of the incubator 10, the bottom surface 320 of the box 300 can completely close the top opening of the incubator 10.

[0045] Depend on Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 As shown, the sprout planting device further includes a box-changing mechanism, which includes a frame 400 on which a first supporting mechanism 100 , a two-axis driving mechanism and a second supporting mechanism 200 are provided.

[0046] The first supporting mechanism 100 is used to lift or release any incubator 10 or the cover. In this way, when multiple incubators 10 are stacked up together, if the first supporting mechanism 100 lifts up a certain incubator 10, all the incubators 10 stacked above it will be lifted together. Specifically, the first supporting mechanism 100 includes a frame body 110. The frame body 110 is provided with a vertical channel 120 for the incubator 10 to pass through. A first support plate 130 is provided on each side of the straight channel 120, and support parts for supporting the first support plates 130 upward are provided on both side walls of the incubator 10 and the cover body. The support parts are generally grooves 310 provided on the side walls of the incubator 10 and the cover body. When the two first support plates 130 extend into the grooves 310 on both sides of the incubator 10 or the cover body, if the two first support plates 130 move upward at the same time, the two first support plates 130 can lift the incubator 10 or the cover body upward.

[0047] The frame body 110 is also provided with a power mechanism for driving the two first support plates 130 to move in relative directions or opposite directions. The power mechanism includes a first motor 140 and two first bidirectional lead screws 150. When the first motor 140 is working, it can drive the two first bidirectional lead screws 150 to rotate forward or reverse synchronously through a belt. Each first bidirectional lead screw 150 is provided with two sections of threads with opposite rotation directions, and the two ends of the two first support plates 130 are respectively fixedly connected with a slider 131. The sliders 131 at both ends of the two first support plates 130 are respectively threadedly connected to the two first bidirectional lead screws 150, and the two sliders 131 threadedly connected to each first bidirectional lead screw 150 are respectively connected to the two sections of threads with opposite rotation directions of their respective first bidirectional lead screws 150. In this way, when the first motor 140 drives the two first bidirectional lead screws 150 to rotate forward or reverse synchronously, each first The two sliders 131 on the bidirectional lead screw 150 move in relative or opposite directions, thereby driving the two first support plates 130 to move in relative or opposite directions, so that the two first support plates 130 are close to or away from each other. When the incubator 10 or the cover body is located between the two first support plates 130, the two first support plates 130 are close to the two side walls of the incubator 10 or the cover body respectively. When the two first support plates 130 are close to each other, the two first support plates 130 respectively enter the grooves 310 on the two side walls of the incubator 10 or the cover body, so that the two first support plates 130 can lift the incubator 10 or the cover body upward. When the incubator 10 or the cover body is moved into place, the two first support plates 130 are separated from each other, so that the two first support plates 130 are disengaged from the grooves 310 on the two side walls of the incubator 10 or the cover body, so that the frame body 110 can move up and down freely.

[0048] The two-axis driving mechanism is used to drive the first supporting mechanism 100 to move horizontally or vertically up and down. In this way, by driving the first supporting mechanism 100 to move vertically up and down by the two-axis driving mechanism, the incubator 10 or the cover body can be moved in the vertical direction. By driving the first supporting mechanism 100 to move horizontally by the two-axis driving mechanism, the incubator 10 or the cover body can be moved in the horizontal direction. In this way, the incubator 10 or the cover body can be transported by the two-axis driving mechanism.

[0049] The second supporting mechanism 200 is located directly above one of the vertical spaces. The second supporting mechanism 200 is used to lift or release the cover body. The second supporting mechanism 200 includes a mounting plate 210. A second motor 220 and a second bidirectional lead screw 230 are provided on the mounting plate 210. When the second motor 220 is working, it can drive the second bidirectional lead screw 230 to rotate forward or reverse. The second bidirectional lead screw 230 is provided with two sections of threads with opposite rotation directions. The two nut sliders 240 are respectively threadedly connected to the two sections of threads with opposite rotation directions of the second bidirectional lead screw 230. In this way, when the second motor 220 drives the second bidirectional lead screw 230 to rotate forward or reverse, the two nut sliders 240 on the second bidirectional lead screw 230 move in relative directions or opposite directions, and the two nut sliders 240 are fixedly connected A second support plate 250 is connected, so that when the two nut sliders 240 move in relative or opposite directions, the two nut sliders 240 can drive the two second support plates 250 to move in relative or opposite directions, thereby making the two second support plates 250 approach or move away from each other. When the cover is located between the two second support plates 250, the two second support plates 250 are respectively close to the two side walls of the cover. When the two second support plates 250 are close to each other, the two second support plates 250 respectively enter the grooves 310 on the two side walls of the cover, thereby making the two second support plates 250 support the cover. When the two second support plates 250 are away from each other, the two second support plates 250 are separated from the grooves 310 on the two side walls of the cover, thereby making the cover supported and moved by the first supporting mechanism 100.

[0050] Before transporting the incubator 10, the first supporting mechanism 100 first lifts the cover and moves it to the position of the second supporting mechanism 200, and then the second supporting mechanism 200 supports and fixes the cover, and then the first supporting mechanism transports the incubator 10 so that the upper opening of each incubator 10 is opened once, thereby allowing the gas in each incubator 10 to be released, so that the gas in each incubator 10 is restored to the atmosphere. After the incubator 10 transport operation is completed, the first supporting mechanism 100 stacks the incubators 10 together again, and then the first supporting mechanism 100 re-carries the cover on the second supporting mechanism 200 to the top of the stacked incubators 10.

[0051] The box-changing mechanism is provided with two vertical spaces 410, which are arranged at intervals in the horizontal direction. The two vertical spaces 410 are used for vertically stacking multiple incubators 10 up and down. The two-axis driving mechanism is used to drive the first supporting mechanism to move back and forth between the two vertical spaces 410 or to move vertically up and down in any vertical space 410. In this way, the incubators 10 are stacked up and down in one of the vertical spaces 410, and the cover is closed on the top incubator 10. When the incubator 10 needs to be changed, the first supporting mechanism 100 will check the cover to The incubator 10 is supported and fixed by the second supporting mechanism 200, and then the first supporting mechanism 100 moves the incubator 10 back and forth between the two vertical spaces 410, so that the gas in each incubator 10 is released and the gas in each incubator 10 is restored to the atmosphere. After the incubator 10 transportation operation is completed, the first supporting mechanism 100 stacks each incubator 10 in one of the vertical spaces 410 again, and then the first supporting mechanism 100 moves the cover on the second supporting mechanism 200 back to the top of the stacked incubators 10.

[0052] In this embodiment, the reason for setting up a box-changing mechanism is that when the concentrations of carbon dioxide and ethylene in the incubator 10 get out of control and exceed the current predetermined concentration, the incubator 10 can be moved through the box-changing mechanism so that the gas and heat in each incubator 10 can be released, so that the gas in each incubator 10 can be restored to the atmosphere.

The structure of the present invention may have other variations and is not limited to the above structure. In short, all variations made within the scope of protection of the independent claims of the present invention are also within the scope of protection of the present invention.
