Description

Technical Field

[0001] The invention relates to the technical field of vegetable cultivation, in particular to a vegetable soilless cultivation system. Background Art

[0002] Vegetable cultivation refers to the process of growing vegetables in a specific environment through artificial means, including soil preparation, sowing, fertilization, irrigation, pest and disease control, etc. The goal is to increase the yield and quality of vegetables to meet people's edible needs. Soilless culture is an agricultural production method that does not rely on soil. It usually uses aqueous solutions, nutrient solutions or other matrices to provide the nutrients needed for plant growth. Common soilless culture techniques include hydroponics, aeroponics and matrix culture. The soilless cultivation method of vegetables reduces dependence on pesticides and produces more environmentally friendly vegetables.

[0003] In the prior art, vegetable matrix cultivation uses a solid matrix to fix the plants and provide certain support for the vegetable roots. The matrix can be an inorganic matrix or an organic matrix, or a mixture of the two. During vegetable matrix cultivation, sufficient and uniform light is crucial to plant growth. In order to make up for insufficient light, fill-in lights are usually installed for supplementary light, but fill-in lights are generally fixed and can only irradiate in a fixed direction, which can easily lead to excessive light on one side of the vegetable and lack of light on the other side, affecting the growth rate and nutrient accumulation of the vegetables, causing uneven growth, and thus affecting the quality and yield of the vegetables.

[0004] Therefore, we propose a vegetable soilless cultivation system to solve the problems raised in the above background technology. Summary of the invention

[0005] The object of the present invention is to provide a vegetable soilless cultivation system to solve the problem that in the vegetable matrix cultivation process proposed in the above background technology, in order to compensate for the lack of light, a fill light is usually installed for fill light. However, the fill light irradiates in one direction, which easily leads to excessive light on one side of the vegetable and lack of light on the other side, affecting the growth rate and nutrient accumulation of the vegetables, causing uneven growth, and thus affecting the quality and yield of the vegetables.

[0006] To achieve the above object, the present invention provides the following technical solution: a vegetable soilless cultivation system, comprising a cultivation component, a multi-angle irradiation component is arranged on the front surface of the cultivation component, and an adjustment component is arranged inside the multi-angle irradiation component;

When the fill light body rotates to the front of the cultivation trough, the output end of the forward and reverse motors will rotate in the opposite direction, driving the fill light body to rotate to the back of the cultivation trough. Through the multi-angle irradiation component, the fill light body rotates in an arc above the vegetables with the fixed shaft as the center, so as to irradiate the vegetables in the cultivation dish with multi-angle fill light, so that the light is evenly irradiated to all parts of the vegetables, reducing the blind spots of illumination, improving the overall efficiency of the fill light system, avoiding the phenomenon of uneven growth caused by excessive local illumination differences, and making the vegetables grow more neatly and healthily.

When the filter that meets the requirements rotates to the bottom of the fill light body, the dual-axis motor is turned off and the work is stopped. After the light emitted by the fill light body passes through the filter of the corresponding color, the light of a specific wavelength is transmitted, and the light of other wavelengths is blocked or absorbed, which changes the spectral composition of the light emitted by the fill light body, making it present different colors, thereby irradiating light of the required color.

The two groups of ring gears 308 are respectively movably sleeved on the outer surfaces of the two irradiation plates 210, and the outer surfaces of the two adjusting rings 305 are equidistantly provided with four mounting holes 306, of which six mounting holes 306 Filters 307 are arranged inside, annular grooves 309 are provided on the inner walls of the two adjustment rings 305 near both sides, five support rods 212 are fixedly installed on the outer surfaces of the two irradiation plates 210 near both sides, five support rods 212 distributed on each circumference of the multiple support rods 212 form a group, one end of the four groups of support rods 212 are movably embedded in the four annular grooves 309, support blocks 304 are fixedly installed on the tops of the two rotating frames 205 near both sides, one end of the four rotating shafts 302 are movably embedded in the outer surfaces of one side of the four support blocks 304, movable holes 213 are provided on the tops of the two rotating frames 205 near both sides, and the outer surfaces of the four adjusting gears 303 are movably embedded in the four movable holes 213, respectively.The bottoms of the two dual-axis motors 301 are fixedly mounted on the tops of the two rotating frames 205, respectively. Two fixed blocks 108 are fixedly mounted on the outer surfaces of both sides of the cultivation frame 101, and the outer surfaces of the four fixed shafts 209 are movably embedded in the four fixed blocks 108. Two fixed frames 102 are bolted inside the cultivation frame 101, and the tops of the two fixed frames 102 are screwed with cultivation troughs 103. Cultivation plates 104 are arranged inside the two cultivation troughs 103, and multiple placement holes 105 are opened on the tops of the two cultivation plates 104. Cultivation dishes 106 are movably embedded in the multiple placement holes 105. Three drainage pipes 107 are fixedly connected to the rear surfaces of the two cultivation troughs 103.

[0037] In this embodiment, when in use, the forward and reverse motors 201, the fill light body 211, the dual-axis motor 301, the light sensor 4 and the PLC controller 5 are electrically connected, and no filter 307 is installed in the mounting hole 306 at the bottom of the adjustment ring 305, and the other three mounting holes 306 are around the outside of the irradiation plate 210, and the two protective plates 214 are located above the side of the mounting hole 306, such as Fig. 9 and Fig.10As shown, the bottom of the fill light body 211 is aligned with the bottom mounting hole 306 and the irradiation hole 215, so that the light of the fill light body 211 can be irradiated downward through the mounting hole 306 and the irradiation hole 215 to irradiate the vegetables. The cultivation medium and vegetable seedlings are placed inside the cultivation dish 106. Water and nutrient solution can be poured into the cultivation dish 106 to provide water and nutrition for the vegetable seedlings. A plurality of drainage holes are provided on the outer surface of the bottom of the cultivation dish 106 so that excess water can flow into the cultivation trough 103 to avoid excessive water and nutrient solution inside the cultivation dish 106, which affects the growth of the vegetable seedlings. One end of the drainage pipe 107 is connected to the external waste liquid tank, so that the accumulated water inside the cultivation trough 103 can be drained into the external waste liquid tank to avoid the accumulated water from polluting the ground. The light sensor 4 is started to detect the external light condition. When light is irradiated on the semiconductor material of the diode, electron-hole pairs are generated inside the material, causing current to flow. The light intensity is proportional to the generated current, so the light intensity can be determined by measuring the current. At the same time, the light sensor 4 transmits the detected light data to the PLC controller 5 in the form of an electrical signal. The maximum and minimum working thresholds of the light data are set in advance inside the PLC controller 5. When the light data received by the PLC controller 5 is lower than the minimum working threshold, the PLC controller 5 controls the fill light body 211 to light up, and irradiate downward through the mounting hole 306 and the irradiation hole 215 to fill light for the vegetable seedlings. At the same time, the forward and reverse motors 201 are started, and the rotation of the output end of the forward and reverse motors 201 drives the driving wheel 202 to rotate, and at the same time drives the chain 203 meshing with it to rotate, and further drives the two driven wheels 204 to rotate together. Under the drive of the two driven wheels 204, the two fixed shafts 209 are driven to rotate inside the corresponding fixed blocks 108, and further drive the rotating plate 208 and the fixed rod 207 to rotate with the fixed shaft 209 as the center of the circle, thereby driving the rotating frame 205, the shading plate 206, the irradiation plate 210 and the fill light body 211 to rotate at the top of the cultivation trough 103. When it rotates to the front of the cultivation trough 103, the output end of the forward and reverse motors 201 will automatically After a pause, it will automatically rotate in the reverse direction, driving the driving wheel 202, the chain 203 and the driven wheel 204 to rotate in the reverse direction, further driving the rotating frame 205, the sunshade 206, the irradiation plate 210 and the fill light body 211 to rotate to the rear of the cultivation trough 103. Through the multi-angle irradiation component 2, the fill light body 211 rotates in an arc above the vegetables with the fixed axis 209 as the center, so as to irradiate the vegetables in the cultivation dish 106 with multi-angle fill light, so that the light is evenly irradiated to all parts of the vegetables, reducing the blind spots of illumination, improving the overall efficiency of the fill light system, avoiding the phenomenon of uneven growth caused by excessive local illumination differences, and making the vegetables grow more neatly and healthily. The rotating irradiation method simulates the changes in natural illumination. In the natural environment, the position of the sun will change over time, and the vegetables will receive light from different angles.The arc-shaped rotation of the fill light body 211 can simulate the change of natural light, so that vegetables can better adapt to the lighting environment. This way of simulating natural light helps vegetables to photosynthesize and grow according to the natural growth law. Under the action of the multi-angle irradiation component 2, the fill light can be rotated at multiple angles, or it can be fixed-point local fill light, which is flexible and convenient. It solves the problem that in the process of vegetable matrix cultivation, in order to make up for the lack of light, fill lights are usually installed for fill light. However, the unidirectional irradiation of the fill light can easily cause one side of the vegetable to receive too much light, while the other side lacks light, which affects the growth rate and nutrient accumulation of the vegetables, causing uneven growth, thereby affecting the quality and yield of the vegetables.

[0038] Embodiment 2: Figure 5-Figure 12 As shown, the adjustment component 3 includes two dual-axis motors 301, and the two output ends of the two dual-axis motors 301 are fixedly installed with rotating shafts 302, and the outer surfaces of the four rotating shafts 302 are fixedly installed with adjusting gears 303. The outer surfaces of the two irradiation plates 210 are movably sleeved with adjusting rings 305, and the outer surfaces of the two adjusting rings 305 are fixedly installed with ring gears 308 near both sides. The outer surfaces of the four adjusting gears 303 are respectively meshed with the outer surfaces of the four ring gears 308, and the two ring gears 308 in each horizontal direction of the four ring gears 308 form a group. The two groups of ring gears 308 are movably sleeved on the outer surfaces of the two irradiation plates 210, and the outer surfaces of the two adjusting rings 305 are evenly spaced with four mounting holes 306, and the six mounting holes 306 are each provided with filters 307. Annular grooves 309 are provided on the inner walls of the two adjustment rings 305 near both sides, five support rods 212 are fixedly installed on the outer surfaces of the two irradiation plates 210 near both sides, five support rods 212 distributed on each circumference of the multiple support rods 212 form a group, one ends of the four groups of support rods 212 are respectively movably embedded in the four annular grooves 309, support blocks 304 are fixedly installed on the tops of the two rotating frames 205 near both sides, one ends of the four rotating shafts 302 are respectively movably embedded in the outer surfaces of one side of the four support blocks 304, movable holes 213 are provided on the tops of the two rotating frames 205 near both sides, the outer surfaces of the four adjusting gears 303 are respectively movably embedded in the four movable holes 213, and the bottoms of the two dual-axis motors 301 are respectively fixedly installed on the tops of the two rotating frames 205.

[0039] In this embodiment, when in use, three different color filters 307 are installed on the outer surface of each irradiation plate 210, namely red, blue and green. Different vegetable varieties and growth stages have different requirements for light intensity and spectrum. For example, in the seedling stage of vegetables, lower intensity blue light may be required to promote the healthy growth of seedlings; while in the flowering and fruiting period, the proportion of red light may need to be increased to stimulate flower bud differentiation and fruit development. The dual-axis motor 301 is started by the PLC controller 5, and the two output ends of the dual-axis motor 301 simultaneously drive the two rotating shafts 302 to rotate, and simultaneously drive the two adjusting gears 303 to rotate in the corresponding movable holes 213, and further drive the two ring gears 308 to rotate. Through the support of the support rod 212 on the adjusting ring 305, the ring gear 308 will drive the adjusting ring 305 to rotate on the outer surface of the irradiation plate 210, so that the mounting hole 306 and the filter 307 rotate on the outer surface of the irradiation plate 210. When the filter 307 that meets the requirements rotates to the bottom of the fill light body 211, the dual-axis motor 301 is turned off and stops working. The filter 307 is an optical element that can selectively transmit or block light of a specific wavelength. By rotating the filter 307 of the corresponding color to the bottom of the fill light body 211, the light emitted by the fill light body 211 passes through the filter 307 of the corresponding color, and the light of a specific wavelength is transmitted, and the light of other wavelengths is blocked or absorbed, thereby changing the spectral components of the light emitted by the fill light body 211, so that it presents different colors, thereby irradiating light of the required color. By adjusting the component 3, light of different colors can be irradiated, which better meets the diverse needs of vegetable growth, improves the fill light effect, and thus improves the quality of vegetable soilless cultivation.

[0040] The effect and working principle of the whole mechanism are as follows: when in use, the cultivation medium and vegetable seedlings are placed inside the cultivation dish 106. By pouring water and nutrient solution into the cultivation dish 106, water and nutrition can be provided for the vegetable seedlings. The outer surface of the bottom of the cultivation dish 106 is provided with multiple drainage holes, so that excess water can flow into the cultivation trough 103 to avoid excessive water and nutrient solution inside the cultivation dish 106, which affects the growth of the vegetable seedlings. One end of the drainage pipe 107 is connected to the external waste liquid tank, and the accumulated water inside the cultivation trough 103 can be drained into the external waste liquid tank. The light sensor 4 is started to detect the external light condition, and the detected light data is transmitted to the PLC controller 5 in the form of an electrical signal. The maximum and minimum working thresholds of the light data are set in advance inside the PLC controller 5. When the light data received by the PLC controller 5 is lower than the minimum working threshold, the PLC controller 5 will control the fill light body 211 to light up, and irradiate downward through the mounting hole 306 and the irradiation hole 215 to fill light for the vegetable seedlings. At the same time, the forward and reverse motors 201 are started, and the rotation of the output end of the forward and reverse motors 201 drives the driving wheel 202 to rotate, and at the same time drives the chain 203 meshing with it to rotate, and further drives the two driven wheels 204 to rotate together. Under the drive of the two driven wheels 204, the two fixed shafts 209 are driven to rotate inside the corresponding fixed blocks 108, and further drive the rotating plate 208 and the fixed rod 207 to rotate with the fixed shaft 209 as the center of the circle, thereby driving the rotating frame 205, the shading plate 206, the irradiation plate 210 and the fill light body 211 to rotate at the top of the cultivation trough 103. When it rotates to the front of the cultivation trough 103, the output end of the forward and reverse motors 201 will automatically After a pause, it will automatically rotate in the opposite direction, driving the driving wheel 202, the chain 203 and the driven wheel 204 to rotate in the opposite direction, further driving the rotating frame 205, the sunshade 206, the irradiation plate 210 and the fill light body 211 to rotate to the rear of the cultivation trough 103. Through the multi-angle irradiation component 2, the fill light body 211 rotates in an arc above the vegetables with the fixed axis 209 as the center of the circle, so as to irradiate the vegetables in the cultivation dish 106 with multi-angle fill light, so that the light is evenly irradiated to all parts of the vegetables, reducing the blind spots of illumination, improving the overall efficiency of the fill light system, avoiding the phenomenon of uneven growth caused by excessive local illumination differences, and making the vegetables grow more neatly and healthily. The rotating irradiation method simulates the changes in natural illumination. In the natural environment, the position of the sun will change over time, and the vegetables will receive illumination from different angles. The arc-shaped rotation of the fill light body 211 can simulate this change in natural illumination, allowing the vegetables to better adapt to the illumination environment. This method of simulating natural light helps vegetables to photosynthesize and grow according to the natural growth law. Under the action of the multi-angle irradiation component 2, the light can be rotated at multiple angles or fixed-point local light can be provided.The dual-axis motor 301 is started by the PLC controller 5, and the two output ends of the dual-axis motor 301 simultaneously drive the two rotating shafts 302 to rotate, and simultaneously drive the two adjusting gears 303 to rotate in the corresponding movable holes 213, and further drive the two ring gears 308 to rotate. Through the support of the support rod 212 on the adjusting ring 305, the ring gear 308 will drive the adjusting ring 305 to rotate on the outer surface of the irradiation plate 210, so that the mounting hole 306 and the filter 307 rotate on the outer surface of the irradiation plate 210. When the filter 307 that meets the requirements rotates to the bottom of the fill light body 211, the dual-axis motor 301 is turned off and stops working. The filter 307 is an optical element that can selectively transmit or block light of a specific wavelength. By rotating the filter 307 of the corresponding color to the bottom of the fill light body 211, the light emitted by the fill light body 211 passes through the filter 307 of the corresponding color, and the light of a specific wavelength is transmitted, and the light of other wavelengths is blocked or absorbed, thereby changing the spectral components of the light emitted by the fill light body 211, so that it presents different colors, thereby irradiating light of the required color. By adjusting the component 3, light of different colors can be irradiated, which better meets the diverse needs of vegetable growth, improves the fill light effect, and thus improves the quality of vegetable soilless cultivation.
