Description

Technical Field

[0001] This invention relates to the field of greenhouse technology, specifically to a greenhouse carbon dioxide fertilizer application device. Background Technology

[0002] With the increasing demand for higher-quality agricultural products and the advancement of agricultural technology, the proportion of facility agriculture, represented by greenhouses, is rising year by year. The prolonged sealing of greenhouses maintains a carbon dioxide concentration of 100-250 ppm, far below the ideal concentration for plant photosynthesis (800-1200 ppm), directly impacting crop photosynthesis, inhibiting fruit and vegetable growth, and significantly reducing planting income. The scientific and standardized application of carbon dioxide to facility agriculture greenhouses can effectively solve the carbon hunger problem in agricultural planting, increase crop yields, optimize crop quality, shorten growth cycles, and promote the modernization of agricultural planting.

[0003] Current greenhouse carbon dioxide fertilization devices typically use a constant flow of carbon dioxide to replenish the greenhouse. However, due to the limited airflow rate inside the greenhouse, when light intensity is high and the plant photosynthetic rate is high, the time it takes for carbon dioxide to diffuse from the gas supply to the crop canopy cannot offset the rate at which photosynthetic carbon dioxide is consumed during periods of strong light. This delayed carbon dioxide supply results in the actual usable carbon dioxide concentration being lower than the light saturation point, creating localized "carbon hunger" that directly limits photosynthetic efficiency. Secondly, when plants of different heights are planted simultaneously in the greenhouse, or when there are plants taller than 1 meter, the carbon dioxide density is significantly greater than that of air. As a result, carbon dioxide gas tends to sink due to gravity, leading to excessively high carbon dioxide concentrations in the low-altitude areas within 1 meter of the ground, while the concentration in the canopy of taller plants is insufficient. This creates a vertical concentration gradient difference that directly restricts the photosynthetic efficiency of tall plants.

[0004] To address the above issues, a carbon dioxide fertilizer application device for greenhouses is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a carbon dioxide fertilizer application device for greenhouses. By using this device, the problems mentioned above can be solved, such as the time it takes for carbon dioxide to diffuse from the gas inlet to the crop canopy cannot offset the rate of carbon dioxide consumption during photosynthesis in strong light periods, and the fact that carbon dioxide gas is more dense than air and tends to sink downwards due to gravity, thus creating a vertical concentration gradient difference.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A carbon dioxide fertilizer application device for a greenhouse includes a greenhouse body.

[0010] Furthermore, the air supply component includes a base plate and a T-shaped plate fixed to one side of the base plate. The base plate is fixedly connected to the greenhouse body. A second pump body is fixedly installed at one end of the T-shaped plate. A third connecting pipe is fixedly installed on one side of the second pump body. The third connecting pipe passes through and connects to one side of the greenhouse body and the support plate. The third connecting pipe is connected to several air jet seats. A fourth connecting pipe is fixedly installed at one end of the second pump body. Two interconnected air supply cylinders are fixedly installed on one side of the base plate.

[0011] Furthermore, the jet mount includes a housing and several jet nozzles fixedly mounted on one side of the housing.

[0012] Furthermore, the drive frame includes a fixed plate and a hydraulic cylinder fixed to one side of the fixed plate. A horizontal plate is fixedly installed at the output end of the hydraulic cylinder, and three sliding plates are fixedly installed on one side of the horizontal plate.

[0013] Furthermore, a round rod is slidably connected to one side of the skateboard, a first spring is fixedly installed inside the skateboard, one end of the first spring is fixedly connected to the round rod, sliders are fixedly installed on both sides of the round rod, both sliders are slidably connected to the inside of the skateboard, and a universal ball bearing is installed at one end of the round rod.

[0014] Furthermore, the lifting component includes a fixing ring and four support rods fixed to one side of the fixing ring. All four support rods are fixedly connected to the greenhouse body. An elastic diaphragm is fixedly installed inside the fixing ring. Two L-shaped plates are fixedly installed on one side of the fixing ring. Both L-shaped plates are fixedly connected to the hammer. A concave plate is fixedly installed on one side of the support rods. The sliding plate is slidably connected to the concave plate.

[0015] Furthermore, the hammering component includes a cylinder and a push rod slidably connected to the cylinder. The cylinder is fixedly connected to two L-shaped plates.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: Carbon dioxide is delivered to the inside of the jet generator through the gas supply component. At this time, the through hole on the baffle is misaligned with the jet generator, and the baffle blocks the jet generator. The gas supply component continues to supply gas, generating high pressure inside the jet generator. The cylinder drives the connecting plate to move, thereby moving the baffle. At this time, the through hole on the baffle coincides with the jet generator. When the pressure is released instantaneously, carbon dioxide gas is ejected from the jet generator at high speed, forming a high-speed airflow. This forces the carbon dioxide gas to be pushed to the crop canopy, shortening the diffusion time and ensuring timely supply of carbon dioxide during periods of strong light. Therefore, the cycle can form a pulsed spray effect.

[0017] A carbon dioxide concentration sensor can acquire real-time data on the carbon dioxide concentration at the bottom of the greenhouse. When the carbon dioxide concentration is high, the drive frame can drive the hammer to move up and down. When the hammer strikes the lifting component rapidly, similar to drumming, this violent impact generates a powerful force on the lifting component, pushing the carbon dioxide gas that was originally deposited at the bottom upward. With the continuous striking of the hammer, periodic pressure pulses are formed, achieving continuous and efficient upward pushing of carbon dioxide gas. This effectively improves the uneven vertical distribution of carbon dioxide within the greenhouse. The pressure pulses generated by the hammer strikes ensure that carbon dioxide quickly reaches the canopy to meet its photosynthetic needs, ensuring that plants of different heights can obtain appropriate concentrations of carbon dioxide at each growth stage.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] To address the technical problem that the time it takes for carbon dioxide to diffuse into the crop canopy cannot offset the rate of carbon dioxide consumption during photosynthesis in strong light periods, resulting in an actual usable carbon dioxide concentration below the light saturation point, such as... Figure 1 , Figure 4 and Figures 6-7 As shown, the following preferred technical solutions are provided: A greenhouse carbon dioxide fertilizer application device includes a greenhouse body 1. An air supply component 2 is installed on one side of the greenhouse body 1 to deliver carbon dioxide, thereby applying the fertilizer to the plants inside the greenhouse body 1. A support plate 3 is fixedly installed inside the greenhouse body 1. Several jet seats 4 are fixedly installed on one side of the support plate 3. Carbon dioxide is delivered to the jet seats 4 through the air supply component 2, and then the jet seats 4 can spray carbon dioxide into the greenhouse body 1. A cylinder 5 is fixedly installed on one side of the support plate 3. A baffle 6 is slidably connected inside the jet seats 4. Several through holes 7 are opened through one side of the baffle 6. Connecting plates 8 are fixedly installed on both sides of the baffle 6.

[0022] When the light intensity is high, carbon dioxide is delivered to the inside of the jet seat 4 through the gas supply component 2. At this time, the through hole 7 on the baffle 6 is misaligned with the jet seat 4, and the baffle 6 blocks the jet seat 4. At this time, the gas supply component 2 continues to supply gas, and high pressure is generated inside the jet seat 4. The cylinder 5 drives the connecting plate 8 to move, thereby driving the baffle 6 to move. At this time, the through hole 7 on the baffle 6 coincides with the jet seat 4. When the pressure is released instantaneously, carbon dioxide gas is ejected from the jet seat 4 at high speed, forming a high-speed airflow, which forcibly pushes the carbon dioxide gas to the crop canopy, shortens the diffusion time, and ensures timely supply of carbon dioxide during periods of strong light.

[0023] Several baffles 6 are connected by connecting plates 8. The connecting plates 8 are slidably connected to the jet seat 4. The output end of the cylinder 5 is fixedly connected to the connecting plates 8. A drive frame 9 is fixedly installed inside the greenhouse body 1. Several lifting parts 10 are evenly distributed inside the greenhouse body 1. A hammer 20 is installed on one side of the lifting part 10. The hammer 20 is in contact with the lifting part 10. The drive frame 9 is connected to the hammer 20.

[0024] The drive frame 9 can drive the hammer 20 to reciprocate up and down. When the hammer 20 strikes the lifting member 10 rapidly, similar to drumming, it generates a violent impact. This violent impact instantly produces a powerful force on the lifting member 10, causing the carbon dioxide gas originally deposited at the bottom to gain an upward thrust. With the continuous striking of the hammer 20, periodic pressure pulses are formed, achieving continuous and efficient upward pushing of carbon dioxide gas. This effectively improves the uneven vertical distribution of carbon dioxide within the greenhouse body 1. The pressure pulses generated by the hammering ensure that carbon dioxide quickly reaches the canopy, meeting its photosynthetic needs. Several carbon dioxide concentration sensors 30 are evenly distributed inside the greenhouse body 1. The carbon dioxide concentration sensors 30 are electrically connected to the drive frame 9 through a controller (the controller is an existing structure and is not shown in the figure). The carbon dioxide concentration sensors 30 can obtain the concentration data of carbon dioxide at the bottom of the greenhouse body 1 in real time. When the carbon dioxide concentration is high, the controller controls the drive frame 9 to make the hammer 20 strike the lifting member 10 quickly, generating a strong impact force, so that the carbon dioxide gas originally deposited at the bottom gets an upward thrust, effectively improving the uneven vertical distribution of carbon dioxide inside the greenhouse body 1.

[0025] The gas supply component 2 includes a base plate 21 and a T-shaped plate 22 fixed to one side of the base plate 21. The base plate 21 is fixedly connected to the greenhouse body 1. A second pump body 23 is fixedly installed at one end of the T-shaped plate 22. A third connecting pipe 24 is fixedly installed on one side of the second pump body 23. The third connecting pipe 24 passes through and connects the greenhouse body 1 and the support plate 3 on one side. The third connecting pipe 24 is connected to several air jet seats 4. A fourth connecting pipe 25 is fixedly installed at one end of the second pump body 23. Two interconnected gas supply cylinders 26 are fixedly installed on one side of the base plate 21. The fourth connecting pipe 25 is connected to the gas supply cylinders 26. The second pump body 23 can transport carbon dioxide inside the gas supply cylinders 26 to the air jet seats 4 through the third connecting pipe 24 via the fourth connecting pipe 25. The carbon dioxide is then transported to the greenhouse body 1 through the air jet seats 4.

[0026] The jet mount 4 includes a housing 41 and several jet nozzles 42 fixedly installed on one side of the housing 41. When the light intensity is high, the second pump body 23 can transport carbon dioxide from the gas supply cylinder 26 to the inside of the jet mount 4 through the third connecting pipe 24 via the fourth connecting pipe 25. At this time, the through hole 7 on the baffle 6 is misaligned with the jet nozzle 42, and the baffle 6 blocks the jet nozzle 42. At this time, the gas supply component 2 continuously supplies gas, and high pressure is generated inside the housing 41. The cylinder 5 drives the connecting plate 8 to move, thereby driving the baffle 6 to move. At this time, the through hole 7 on the baffle 6 coincides with the jet nozzle 42. When the pressure is released instantaneously, carbon dioxide gas is ejected from the jet nozzle 42 at high speed, forming a high-speed airflow, which forcibly pushes the carbon dioxide gas to the crop canopy, shortens the diffusion time, and ensures timely supply of carbon dioxide during the strong light period. Therefore, the cycle can form a pulse jet effect.

[0027] To address the technical problem of carbon dioxide's significantly higher density than air, causing it to sink due to gravity, and the insufficient concentration of carbon dioxide in the plant canopy at higher elevations, which directly restricts the photosynthetic efficiency of tall plants, such as... Figure 5 and Figures 8-11 As shown, the following preferred technical solutions are provided: The greenhouse body 1 has several planting racks 19 evenly distributed inside, through which plants can be placed for planting. The drive frame 9 includes a fixed plate 91 and a hydraulic cylinder 92 fixed to one side of the fixed plate 91. A horizontal plate 93 is fixedly installed at the output end of the hydraulic cylinder 92, and three sliding plates 94 are fixedly installed on one side of the horizontal plate 93. The controller can control the first pump body 12 and the hydraulic cylinder 92. When there is no sunlight and the carbon dioxide concentration at the bottom of the greenhouse body 1 is high, the controller can control the first pump body 12 to draw carbon dioxide, which can reduce the carbon dioxide concentration at the bottom of the greenhouse body 1 and avoid inhibiting plant respiration due to excessive concentration. When there is continuous sunlight and the carbon dioxide concentration at the bottom of the greenhouse body 1 is high, the controller controls the hydraulic cylinder 92 to work, driving the hammer 20 to quickly strike the lifting member 10, so that the carbon dioxide gas originally deposited at the bottom gains upward thrust, effectively improving the uneven vertical distribution of carbon dioxide in the greenhouse body 1. Therefore, it can be used according to specific needs.

[0028] A round rod 941 is slidably connected to one side of the slide plate 94. A first spring 942 is fixedly installed inside the slide plate 94. One end of the first spring 942 is fixedly connected to the round rod 941. Slider 943 is fixedly installed on both sides of the round rod 941. Both sliders 943 are slidably connected to the inside of the slide plate 94. A universal ball bearing 944 is installed at one end of the round rod 941. The universal ball bearing 944 can reduce friction.

[0029] The lifting component 10 includes a fixed ring 101 and four support rods 102 fixed to one side of the fixed ring 101. All four support rods 102 are fixedly connected to the greenhouse body 1. An elastic diaphragm 103 is fixedly installed inside the fixed ring 101. When the elastic diaphragm 103 is struck, the upward impact force of the elastic diaphragm 103 forms a periodic pressure pulse, realizing the continuous and efficient upward push of carbon dioxide gas. Two L-shaped plates 104 are fixedly installed on one side of the fixed ring 101. Both L-shaped plates 104 are fixedly connected to the hammer 20. A concave plate 105 is fixedly installed on one side of the support rods 102. The sliding plate 94 is slidably connected to the concave plate 105. The horizontal plate 93 and the three sliding plates 94 can be moved by the hydraulic cylinder 92. The sliding plate 94 moves on the concave plate 105, thereby driving the round rod 941 to move. The movement of the round rod 941 generates pressure on the hammer 20, thereby creating a striking effect.

[0030] The hammer 20 includes a cylinder 201 and a push rod 202 slidably connected to the cylinder 201. The cylinder 201 is fixedly connected to two L-shaped plates 104, which serve to fix the cylinder 201. A ball 203 is fixedly connected to one end of the push rod 202, and the ball 203 contacts the elastic diaphragm 103, striking the diaphragm 103. A disc 204 is fixedly mounted to one end of the push rod 202, and the disc 204 is slidably connected to the inner wall of the cylinder 201. Movable rods 205 are fixedly mounted on both sides of the disc 204, limiting the movement of the disc 204. A second spring 206 is fixedly installed on one side of the disc 204, which is slidably connected to the cylinder 201. One end of the second spring 206 is fixedly connected to the inside of the cylinder 201. The second spring 206 can provide elastic force. A movable block 207 is fixedly installed on one side of the disc 204, which is slidably connected to the cylinder 201. A triangular plate 208 is fixedly installed on one side of the movable block 207. A round rod 941 contacts the triangular plate 208. The round rod 941 contacts the inclined surface of the triangular plate 208. The triangular plate 208 is similar to a right triangle structure. An inclined groove 209 is opened on one side of the triangular plate 208, and one side of the inclined groove 209 is an inclined surface.

[0031] The hydraulic cylinder 92 allows the horizontal plate 93 and the three sliding plates 94 to move. The sliding plates 94 move on the concave plate 105, which in turn moves the round rod 941. At this time, the round rod 941 moves on the inclined surface of the triangular plate 208, which causes the triangular plate 208 to move the moving block 207 and the disc 204 downward. The downward movement of the disc 204 can compress the second spring 206 until the round rod 941 separates from the triangular plate 208. At the same time, due to the elastic force of the second spring 206, the disc 204, the push rod 202 and the ball 203 move upward instantly, which is similar to the way a drum is struck, and the elastic diaphragm 103 is struck rapidly. This violent impact instantly generates a strong impact force on the elastic diaphragm 103, which gives the carbon dioxide gas that was originally deposited at the bottom an upward thrust.

[0032] Subsequently, hydraulic cylinder 92 drives slide plate 94 to move in the opposite direction, causing round rod 941 to move into inclined groove 209. The inclined groove 209 then limits the movement of triangular plate 208, causing moving block 207 and disc 204 to move downwards, and compressing the second spring 206 again. Due to the limiting effect of the inclined surface on one side of inclined groove 209, round rod 941 moves into slide plate 94 and compresses the first spring 942. When round rod 941 moves out of inclined groove 209 and contacts triangular plate 208 on one side, due to the universal joint... As the ball bearing 944 rotates, the second spring 206 pushes the disc 204, the top rod 202, and the ball 203 upwards instantly, striking the elastic diaphragm 103 rapidly again, similar to drumming. This creates a reciprocating and rapid striking of the elastic diaphragm 103, improving the effect and effectively mitigating the uneven vertical distribution of carbon dioxide within the greenhouse body 1. The pressure pulse generated by the hammering ensures that carbon dioxide quickly reaches the canopy, meeting its photosynthetic needs and ensuring that plants of different heights can obtain appropriate concentrations of carbon dioxide at each growth stage.

[0033] To address the technical problem of increased plant respiration at nightfall leading to a gradual rise in carbon dioxide concentration at the bottom, which can inhibit plant respiration due to excessively high concentrations, such as... Figures 2-4 As shown, the following preferred technical solutions are provided: A storage box 11 is fixedly installed on one side of the greenhouse body 1. A first pump body 12 is connected to one end of the storage box 11. A carbon dioxide concentration sensor 30 is electrically connected to the first pump body 12 via a controller. A first connecting pipe 13 is connected to one end of the first pump body 12 and runs through one side of the greenhouse body 1. A diversion pipe 14 is installed inside the greenhouse body 1 and is connected to the first connecting pipe 13. Several L-shaped pipes 15 are connected through one side of the greenhouse body 1, and the L-shaped pipes 15 are evenly spaced. Inside the greenhouse body 1, several L-shaped pipes 15 are connected to the diversion pipe 14. Through the first pump body 12, the first connecting pipe 13 and the diversion pipe 14, the L-shaped pipes 15 can absorb the carbon dioxide with a high concentration at the bottom of the greenhouse body 1. A bracket 16 is fixedly installed at one end of the L-shaped pipe 15 and is fixedly connected to the greenhouse body 1. A second connecting pipe 17 is connected to one side of the storage box 11 and is connected to the gas supply component 2. A one-way valve 18 is installed on one side of the second connecting pipe 17.

[0034] As night falls, plant respiration intensifies, and the carbon dioxide concentration at the bottom gradually increases. At this time, the carbon dioxide concentration sensor 30 detects the high carbon dioxide concentration at the bottom of the greenhouse body 1 and controls the first pump 12 to operate via the controller. The first pump 12, the first connecting pipe 13, and the diversion pipe 14, together with the L-shaped pipe 15, can absorb the high concentration of carbon dioxide at the bottom of the greenhouse body 1 and pump a portion of the carbon dioxide into the storage tank 11 for storage. Timely removal of high-concentration carbon dioxide from the bottom can stably control the carbon dioxide concentration of the greenhouse body 1 at night, avoiding inhibition of plant respiration due to excessive concentration. Therefore, the carbon dioxide inside the storage tank 11 can serve as a backup. When the carbon dioxide inside the gas supply component 2 is used up, the one-way valve 18 is opened, and the gas supply component 2 can promptly deliver the carbon dioxide from the storage tank 11 to the greenhouse body 1, forming a seamless gas supply and preventing the phenomenon of carbon dioxide interruption. Therefore, the addition of the suction and circulation structure can effectively recover gas and improve resource utilization.

[0035] An arc-shaped plate 161 is slidably connected to one end of the bracket 16. The arc-shaped plate 161 is slidably connected to the L-shaped tube 15. The friction between the arc-shaped plate 161 and the L-shaped tube 15 allows the arc-shaped plate 161 to be stably installed on the bracket 16. A pull ring 162 is fixedly installed on one side of the arc-shaped plate 161. The arc-shaped plate 161 can be easily disassembled by pulling the pull ring 162. A filter screen 163 is fixedly installed on one side of the arc-shaped plate 161. The filter screen 163 is in contact with the inner wall of the L-shaped tube 15. A non-woven fabric filter element 164 is fixedly installed on the side of the arc-shaped plate 161 near the filter screen 163. The non-woven fabric filter element 164 is in contact with the inner wall of the L-shaped tube 15. The filter screen 163 and the non-woven fabric filter element 164 form primary filtration and secondary filtration, which are used to block large particles and capture small particles, purify the gas, and ensure the purity of the stored carbon dioxide gas.
