Description

Technical Field

[0001] This invention relates to seed and seedling cultivation, belonging to the field of breeding and cultivation, specifically an agricultural breeding and cultivation device. Background Technology

[0002] Agricultural breeding is the core of modern agricultural development; the growth of seedlings depends on precise environmental control, especially for the cultivation of off-season crops. Existing technologies mostly use cultivation devices such as artificial climate chambers, tissue culture racks, or small environmental control chambers, which integrate heating, ventilation, and humidification modules to create a stable local environment for breeding.

[0003] However, existing cultivation devices of this type have independent design and stacking of various environmental control modules (such as heating, ventilation, and humidification) in terms of overall design and integration, which makes the device structure complex, occupies a large space, and has high manufacturing costs. While they can be used in the laboratory, they are not suitable for outdoor simulation experiments (such as greenhouse simulation experiments and off-site soil selection experiments). These devices are difficult to move or transport, and are not convenient to carry and set up at any time. Therefore, this invention provides an agricultural breeding cultivation device. Summary of the Invention

A hollow short section is fixedly connected to the bottom of the pressure balancing groove. The short section and the skeleton assembly form an air passage that connects the pressure balancing groove and the inside of the cultivation area.

[0007] Preferably, the bottom of the hollow shell is fixedly connected to a mesh frame via a short frame, the branch channel is fixedly connected to the mesh frame, and the mesh frame is fixedly connected to the short section.

[0008] Preferably, the pressure balancing groove and the left end of the hollow shell are both connected to a grid.

A fertilizer base is installed at the bottom end of the water guide cylinder. A water guide pipe is fixedly connected to the side of the water guide cylinder. The water guide pipe has a through side hole. The fertilizer base includes an inner cylinder, an inner support plate is fixedly connected to the inner side of the inner cylinder, and a mesh portion is provided on the side of the inner cylinder above the inner support plate. A porous cotton block assembly is disposed inside the water guide cylinder.

[0012] Preferably, the porous cotton block assembly includes: The main body has a water-immersing part at its bottom that corresponds to the water tank.

[0014] Preferably, the gas circulation assembly includes: a circulation pump, the outlet of which is connected to the inlet port via an airflow pipe, and the inlet of which is connected to the transparent cover via an airflow pipe.

[0015] This invention provides an agricultural breeding and cultivation device.

[0016] This invention improves the structure of the top surface, which includes a hollow shell, branch channels, a heating module, and a flow-dividing adjustment component. When the temperature inside the cultivation area is lower than a predetermined requirement, the gas circulation component operates, sending a portion of the gas from the cultivation area into the main gas channel. The flow-dividing adjustment component is then turned off, guiding the gas entering the main gas channel into the branch channels. The heating module heats the gas passing through the branch channels, and the heated gas is discharged from the bottom of the branch channels back into the cultivation area. This process of gas circulation within the cultivation area heats the gas inside. If the CO2 concentration inside the cultivation area is high, requiring the introduction of external gas, the gas is controlled... When the circulation component operates, some of the gas inside the cultivation area is sent into the main air duct. The flow distribution regulating component is adjusted to the open state, and some of the gas entering the main air duct will be guided into the branch channel. The heating module heats the gas passing through the branch channel. The heated gas is discharged into the cultivation area from the bottom of the branch channel, while another part of the gas will flow directly out from the left end of the hollow shell through the opening of the flow distribution regulating component. During this circulation process, the amount of gas inside the cultivation area decreases and the air pressure decreases. Outside gas can flow into the cultivation area from the watering and ventilation component (this part is cold gas). The above-mentioned circulated heated gas mixes with the cold gas to ensure that the temperature inside the cultivation area is within the predetermined range. Attached Figure Description

[0019] 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. Example

[0020] like Figures 1-13 As shown, this embodiment of the invention provides an agricultural breeding and cultivation device, which relates to seed and seedling cultivation and belongs to the field of breeding and cultivation. It is used in outdoor simulation experiments, such as greenhouse simulation experiments and off-site soil selection experiments. It is easy to carry and set up, and the experimenters can set it up directly in the experimental field. Specifically, it includes: a skeleton component 6, a transparent cover 4, a top structure 1, a watering and ventilation component 5, and an external gas circulation component.

[0021] The skeleton component 6 is inserted into the ground to form an enclosed area. The top structure 1 is fixedly installed on the top of the skeleton component 6. A transparent cover 4 is connected to the outside of the skeleton component 6 and the bottom of the top structure 1. The inside of the transparent cover 4 and the bottom of the top structure 1 form a cultivation area. This cultivation area is a relatively sealed space, and the ground at its bottom is the crop area for planting crops. The watering and ventilation component 5 is set on the side of the transparent cover 4. The experimenter waters through the watering and ventilation component 5, which guides the water to the crop area to water the planted crops. The air passage formed by the watering and ventilation component 5 is used for external gas to enter the cultivation area and adjust the CO2 concentration inside the cultivation area.

[0022] The skeleton component 6 can be quickly installed in the prepared experimental field and the top structure 1, transparent cover 4, watering and ventilation component 5 are installed. Finally, the gas pipeline of the gas circulation component is connected, thus quickly forming an agricultural breeding and cultivation area. Compared with traditional equipment, it has the advantages of simple structure, easy-to-carry components, low equipment cost, and rapid deployment in the experimental planting area.

[0023] Specifically, the structure of the top surface structure 1 is improved, which includes: a hollow shell 101, a branch channel 109, a heating module 1010, and a flow diversion adjustment component 103.

[0024] The hollow shell 101 has openings at both its left and right ends, thus forming a main air passage inside the hollow shell 101. An air inlet 102 is fixedly installed at the right end of the hollow shell 101 for connecting to the air outlet of the gas circulation component. When the gas circulation component is working, it extracts the gas inside the cultivation area and pumps it into the main air passage through the air inlet 102. The top end of the branch passage 109 is fixedly connected to the bottom of the hollow shell 101. A heating module 1010 is fixedly installed inside the branch passage 109. The heating module 1010 can be an electric heating grid or a PTC ceramic heater. The heating module 1010 is used to heat the gas passing through the branch passage 109. A diversion adjustment component 103 is installed on the left side of the hollow shell 101, at the connection between the branch passage 109 and the hollow shell 101. A gas circulation component is installed between the air inlet 102 of the hollow shell 101 and the cultivation area.

[0025] When the temperature inside the cultivation area is lower than the predetermined requirement, the gas circulation component operates, sending a portion of the gas from the cultivation area into the main gas duct. The flow diversion regulating component 103 is then adjusted to the closed state, and the gas entering the main gas duct is guided into the branch channel 109. The heating module 1010 heats the gas passing through the branch channel 109, and the heated gas is discharged into the cultivation area from the bottom of the branch channel 109. This process of gas circulation within the cultivation area heats the gas inside. If the CO2 concentration inside the cultivation area is high, requiring the introduction of external gas, the gas circulation component is controlled to operate, sending a portion of the gas from the cultivation area into the main gas duct. The flow diversion regulating component 103 is then adjusted to the open state (the flow diversion regulating component...). 103 is adjusted to a state between fully open and fully closed (the ratio of exhaust and recirculation airflow can be adjusted). Part of the gas entering the main air duct will be guided into the branch duct 109. The heating module 1010 heats the gas passing through the branch duct 109. The heated gas is discharged into the cultivation area from the bottom of the branch duct 109, while another part of the gas will flow directly out from the left end of the hollow shell 101 through the opening of the diversion adjustment component 103. In this cycle, the amount of gas inside the cultivation area decreases and the air pressure decreases. Outside gas can flow into the cultivation area from the watering and ventilation component 5 (this part is cold gas). The above-mentioned circulating heated gas mixes with the cold gas to ensure that the temperature inside the cultivation area is within the predetermined range.

[0026] In one embodiment, a pressure balancing groove 106 is integrally provided below the hollow shell 101 and near its left end. A baffle 107 is fixedly connected to the inner side of the hollow shell 101 to guide gas into the pressure balancing groove 106. A hollow section 104 is fixedly connected to the bottom of the pressure balancing groove 106. The section 104 and the skeleton assembly 6 form an air passage connecting the pressure balancing groove 106 to the inside of the cultivation area. Thus, the inside of the cultivation area is connected to the outside through the air passage formed by the section 104 and the skeleton assembly 6. When the CO2 concentration is high and external gas is introduced, if the gas pressure inside the cultivation area is unstable, the gas will reach the pressure balancing groove 106 through the main air passage. The gas in the balancing tank 106 region (hot gas during the circulation process) can flow into the cultivation area through the air passage formed by the short section 104 and the skeleton assembly 6. Of course, if the gas pressure inside the cultivation area is stable, the gas flowing through the pressure balancing tank 106 will form a negative pressure at the top port of the short section 104, which will hinder the gas from passing through the pressure balancing tank 106 (decelerating the gas passing through the pressure balancing tank 106) and at the same time drive some of the gas inside the cultivation area to flow to the outside through the air passage formed by the short section 104 and the skeleton assembly 6. The above two methods are dynamic processes, which can ensure the stability of the gas pressure inside the cultivation area (during the heating / CO2 concentration adjustment process).

[0027] In one embodiment, the bottom of the hollow shell 101 is fixedly connected to a mesh frame 108 via a short frame, the branch channel 109 is fixedly connected to the mesh frame 108, and the mesh frame 108 is fixedly connected to the short section 104.

[0028] Generally, four sets of short frames need to be designed. Two short sections 104 can replace the short frames, that is, design two short frames and two short sections 104 to install the space frame 108. The space frame 108 is used to protect the branch channel 109.

[0029] In one embodiment, the pressure balancing groove 106 and the left end of the hollow shell 101 are connected to a grille 105, which is used to block external debris from entering the pressure balancing groove 106.

[0030] In one embodiment, the diversion adjustment assembly 103 includes: a shaft 1031 and a kit 1032.

[0031] The shaft 1031 is longitudinally rotatably mounted inside the hollow housing 101. A cap 1034 is fixedly mounted on the first end of the shaft 1031, and a rotating plate 1035 is fixedly mounted on the second end of the shaft 1031. After the cap 1034 and the rotating plate 1035 are installed, the shaft 1031 is restricted from moving longitudinally. Generally, a bushing needs to be designed at the connection between the shaft 1031 and the hollow housing 101. The kit 1032 is fixedly mounted in the middle of the shaft 1031, and two sets of blades 1033 are symmetrically fixed on the side of the kit 1032.

[0032] The user manipulates the rotating blade 1035 to rotate the shaft 1031. The shaft 1031 drives the kit 1032 and the two sets of blades 1033 to rotate synchronously. When the two sets of blades 1033 are in a vertical state, they can block the inner section of the hollow shell 101, which is the closed state. When the two sets of blades 1033 are in a horizontal state, there are gaps between the inner section of the hollow shell 101 and the upper and lower sides of the blades 1033, which is the open state.

[0033] In one embodiment, the frame assembly 6 includes four sets of grounding rods. The four sets of grounding rods can be used individually or connected with crossbars between two adjacent grounding rods to form two combined structures.

[0034] Each set of ground poles includes: a hollow pole 601 and a foot piece. The hollow pole 601 has an air hole 602 on its side. The foot piece includes: a threaded section 603. The bottom end of the threaded section 603 is integrally provided with a pointed section 604. A support ring 605 is threaded on the threaded section 603. The bottom end of the hollow pole 601 is sleeved on the threaded section 603.

[0035] When using it, first locate and mark the positions of the four sets of ground poles on the prepared ground; drive the anchors into the soil at the marked positions. After all the anchors are installed, rotate the support rings 605 on them to keep the support rings 605 of the four sets of anchors on the same horizontal plane as much as possible. Finally, install the hollow pole 601; then fix the top structure 1 on the top of the hollow pole 601 and connect the transparent cover 4.

[0036] In one embodiment, a back plate 404 is fixedly connected to the back of the transparent cover 4, and a side hole 405 is provided on the side of the back plate 404. The side hole 405 is used for the water guide pipe 504 of the watering and ventilation component 5 to extend into the cultivation area.

[0037] The watering and ventilation assembly 5 includes: a water trough 501, a water guide cylinder 503, a water guide pipe 504, a fertilizer base 506, and a porous cotton block assembly 507.

[0038] A support member 505 is fixedly connected to the bottom of the water tank 501. The support member 505 supports the water tank 501, preventing the watering and ventilation component 5 from exerting force on the transparent cover 4. A water storage part 502 is fixedly provided at the bottom of the water tank 501. The water storage part 502 is connected to the inner bottom of the water tank 501. The water inside the water storage part 502 will not flow out and will remain for a long time. The top of the water guide cylinder 503 is fixedly connected to the bottom of the water tank 501. The bottom of the 3 is equipped with a fertilizer base 506, and a water guide pipe 504 is fixedly connected to the side of the water guide cylinder 503. The water guide pipe 504 has a through side hole 405. The fertilizer base 506 includes: an inner cylinder 5061, an inner support piece 5062 is fixedly connected to the inner side of the inner cylinder 5061, and a mesh part 5063 is opened on the side of the inner cylinder 5061 and above the inner support piece 5062. A porous cotton block assembly 507 is disposed inside the water guide cylinder 503.

[0039] When watering, the user adds water into the water tank 501 from the outside of the transparent cover 4. The water flows downward through the water guide tube 503 and flows from the water guide pipe 504 to the ground corresponding to the bottom of the cultivation area.

[0040] When fertilization is needed, pull the fertilizer base 506 downwards and add an appropriate amount of water-soluble fertilizer to the area above the inner plate 5062 of the fertilizer base 506. When watering later, the water passes through the water guide tube 503 and enters the area above the inner plate 5062 in the inner cylinder 5061, dissolving the water-soluble fertilizer and flowing from the water guide pipe 504 to the ground corresponding to the bottom of the cultivation area.

[0041] The porous cotton block assembly 507 is installed inside the water guide cylinder 503, and the porous cotton block assembly 507 will be wetted every time water is poured. When adjusting the CO2 concentration, the external gas passes through the watering and ventilation assembly 5, that is, through the porous cotton block assembly 507 inside the water tank 501. The wetted porous cotton block assembly 507 humidifies the gas. Of course, in places where humidification is not required, the porous cotton block assembly 507 can be directly removed.

[0042] In one embodiment, the porous cotton block assembly 507 includes: a main body 5071, a water-soaking part 5072, a covering fabric 5073, and a sheet 5074.

[0043] The bottom of the main body 5071 is provided with a water immersion part 5072 corresponding to the water tank 501. The water immersion part 5072 is always immersed in water. Under capillary action, the main body 5071 will always be kept moist. Both the main body 5071 and the water immersion part 5072 are made of sponge material. The sponge material has water absorption and a porous shape. The inside of the water immersion part 5072 is embedded with a covering fabric 5073. An internal sheet 5074 extending to the main body 5071 is integrally provided on the covering fabric 5073. The covering fabric 5073 and the sheet 5074 are made of cloth, which has a better capillary effect, keeping the porous cotton block component 507 moist for a long time. In addition, the addition of the covering fabric 5073 and the sheet 5074 makes it less likely to be torn compared to the simple sponge material.

[0044] In one embodiment, the bottom of the transparent cover 4 has an outwardly extending edge 401, which is laid on the ground and covered with a layer of soil. The front side of the transparent cover 4 has a zipper-type operating section 402. When the zipper-type operating section 402 is opened, the user can operate the crops inside the cultivation area. A sensor module 406 is fixedly installed on the inner side of the transparent cover 4. The sensor module 406 generally includes a temperature sensor and a CO sensor. 2浓度 Sensors, humidity sensors, etc., are included, and a display screen is provided for real-time display.

[0045] In one embodiment, the gas circulation assembly includes: a circulation pump 2, the outlet of the circulation pump 2 is connected to the inlet port 102 through the airflow pipe 3, the inlet of the circulation pump 2 is connected to the transparent cover 4 through the airflow pipe 3, and the circulation pump 2 enters the hollow shell 101 through the airflow pipe 3 by the power of the airflow, and then performs internal and external circulation.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
