Description

Technical Field

[0001] The present invention relates to the field of seed culture equipment, and in particular to a culture equipment for comparative detection of rice germplasm resources. Background Art

[0002] Comparative testing of rice germplasm resources is crucial for rice variety improvement and sustainable agricultural development. Testing items include appearance testing, genetic testing, phenotypic testing, etc. Phenotypic testing includes data such as germination rate, plant height, and seedling growth. The corresponding cultivation equipment is needed to cultivate rice seeds to the seedling stage before relevant testing can be carried out.

[0003] Chinese patent CN118923400A discloses a rice salt-alkali tolerance detection and cultivation device. The device can cultivate multiple different varieties of rice in the same cultivation box by setting a cultivation mechanism, and each rice plant occupies a separate cultivation box, which is convenient for marking rice and detecting a single rice plant, and is convenient for taking it out for viewing; it is used to solve the problem that it is not convenient to take out different varieties of rice in the same cultivation box for viewing separately in existing equipment.

[0004] However, the above device has some shortcomings when used. In the initial stage of rice cultivation, rice seeds are placed in a planting basket, and the cultivation equipment is in a relatively closed box. Since the temperature requirement of rice seeds before germination is high, if the rice seeds are stacked on each other or in a static state for a long time, the local temperature of the seeds will be relatively high, which will cause the rice seeds to fail to germinate normally. Therefore, the rice seeds need to be turned frequently. The device disclosed in the above patent cannot realize automatic turning of rice seeds. Using manual turning is not only inefficient, but also easily causes external pollutants to contaminate the nutrient solution if the staff makes mistakes in operation.

[0072] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0073] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0074] like Figure 1 , Figure 2 and Figure 3 As shown, the cultivation equipment for comparative detection of rice germplasm resources includes: a casing 1, an exhaust fan 2, a cultivation chamber 3, a cultivation box 4, a planting basket 5, a connecting mechanism 6, an air pump 7, a water bucket 9 and a water pump 10. The casing 1 is a hollow cavity, and there are two exhaust fans 2 installed on the outer wall of the casing 1 to realize the air exchange between the inner cavity space of the casing 1 and the outside. The cultivation chamber 3 is located in the casing 1, and the internal space of the casing 1 is divided into a plurality of cultivation chambers 3 by a plurality of partitions. The cultivation box 4 is installed in the cultivation chamber 3. As shown Figure 5 and Figure 6As shown, a plurality of culture compartments 401 are provided in the incubator 4, and the inner cavity of the incubator 4 is divided into a plurality of rectangular cavities with top openings by partitions, and each cavity is independently arranged to hold nutrient solution for cultivating rice, and these cavities are culture compartments 401. Since the culture compartments 401 in the incubator 4 are not interconnected, different types of rice can be cultivated independently, so that it is convenient to take different types of rice for comparison and detection. In this embodiment, the number of culture compartments 401 is four, and they are arranged in a field shape. The planting basket 5 is installed in the incubator 4, and the planting basket 5 is a hollow structure with an open top. A plurality of through grooves 501 are provided on the lower surface of the planting basket 5. The height of the planting basket 5 is less than the depth of the incubator 4, and a frame is provided on the planting basket 5. When the planting basket is placed in the incubator 4, the planting basket 5 can be stably placed in the culture compartment 401 through the overlap limit of the frame and the incubator 4. At this time, the upper surface of the planting basket 5 is higher than the upper surface of the incubator 4 by the thickness of the frame, and the lower surface of the planting basket 5 is suspended. When the planting basket 5 is in use, gravel, ceramsite, planting sponge, etc. are placed inside to fix the rice root system. In this embodiment, ceramsite is selected. In the rice germination stage, the rice seeds soaked in the nutrient solution are placed on the surface of the ceramsite, and the lower surface of the planting basket 5 is ensured to be immersed in the nutrient solution. The surface of the ceramsite in the planting basket 5 is higher than the nutrient solution level. The nutrient solution can enter the planting basket 5 through the through groove 501. By utilizing the special pore structure of the ceramsite, the nutrient solution moves upward along the gap to the surface layer, so that the surface ceramsite remains moist, thereby ensuring that the seeds will not be completely immersed in the nutrient solution, and can also ensure that the seeds absorb enough nutrition. In this embodiment, the culture box 4 also includes an overflow trough 402 and a discharge port 403. The overflow trough 402 is opened on the upper surface of the culture box 4. The overflow trough 402 is composed of a plurality of trough bodies arranged in a crisscross pattern and interconnected with each other, ensuring that the culture compartment 401 is surrounded by the trough body of the overflow trough 402. The discharge port 403 is opened on the culture box 4, and the discharge port 403 is connected to the overflow trough 402. When the planting basket 5 in the culture compartment 401 is filled with expanded clay, the nutrient solution above the culture compartment 401 will enter the overflow trough 402 and finally be discharged through the discharge port 403 to prevent the nutrient solution from submerging the surface expanded clay.

[0075] The above structure can not only cultivate a variety of different rices independently at the same time, but also ensure that different types of rice do not affect each other, so that it is convenient to take different types of rice for comparison and detection to determine the germplasm; through the setting of the planting basket 5, it can stably ensure that the rice can stably absorb nutrients during the germination stage. At the same time, the overflow trough 402 can be used to discharge the nutrient solution that is about to cover the rice seeds, so as to prevent excessive nutrient solution from affecting the germination of the seeds. Moreover, the overflow trough 402 surrounding the culture compartment 401 can be used to directly discharge the overflowed nutrient solution, so as to prevent the nutrient solution from flowing into other culture compartments, causing the pathogenic bacteria that affect the germination and growth of seeds to be transferred to other rice cultivation spaces. In addition, the scheme can realize the rapid circulation and exchange of air through the exhaust fan 2, avoid the imbalance of the ratio of oxygen and carbon dioxide in the culture chamber 3 in the box 1, contribute to the normal growth of the seedling stage, and facilitate the acquisition of accurate detection data.

[0076] like Figure 3 and Figure 4 As shown, a fill light 11 is installed on the inner wall of the culture chamber 3, and the position of the fill light 11 corresponds to the position of the culture box 4. In this embodiment, a HW100W fill light is selected to meet the lighting requirements for rice growth.

[0077] like Figure 7 , Figure 8 and Fig. 9 The connecting mechanism 6 is installed on the incubator 4, and the number of the connecting mechanisms 6 corresponds to the number of the culture compartments 401. In this embodiment, there are four connecting mechanisms 6, and the four connecting mechanisms 6 correspond to the four culture compartments 401. It is used to control the replenishment of materials to the culture compartments 401 in the incubator 4, including the replenishment of air and nutrient solution.

[0078] The connecting mechanism 6 includes: a shell 61, a connector 62, a piston 63, a spring 64, a channel 65, a stopper 66 and an extension tube 67. The shell 61 is mounted on the incubator 4. There are two connectors 62, which are symmetrically arranged relative to the shell 61. The connectors 62 are connected to the inner cavity space of the shell 61. The piston 63 is slidably mounted in the inner cavity of the shell 61, and the piston 63 contacts the inner wall of the shell 61. Rubber sealing pads are respectively arranged at both ends of the piston 63 to ensure that the spaces at both ends of the piston are independent of each other. There are two channels 65, which are respectively symmetrically opened on the piston 63. The cross-section of the channel 65 is L-shaped when viewed from above. The materials in the space on both sides of the piston 63 can enter the two channels 65 respectively. There are two stopper seats 66, which are symmetrically mounted in the shell 61 relative to the piston 63. The cross-section of the stopper seat 66 is T-shaped, and a through hole is arranged in the middle of the stopper seat 66. The stopper seat 66 is used to limit the piston 63 so as to limit the moving range of the piston 63. There are two springs 64, which are respectively installed between the piston 63 and the two limiting seats 66. In the natural state, the piston 63 is stably located in the middle of the shell 61 by the common limiting of the spring 64 and the limiting seat 66. When one side of the piston 63 is subjected to external force or is moved to the other side, the spring 64 on the side subjected to force is stretched, while the spring 64 on the other side is compressed. After the external force is removed, the piston 63 is quickly reset by the tension and elastic force of the springs 64 on both sides. There are two extension tubes 67, which are installed on the shell 61, and the extension tubes 67 extend into the incubator 4, and the extension tubes 67 are connected to the inner cavity of the shell 61. The air pump 7 is installed on the box body 1, and the output end of the air pump 7 is connected to the connector 62 on one side of the connecting mechanism 6 through a hose 8. In this embodiment, the ACQ-4000 air pump is selected. When the air pump 7 is turned on, it can inflate the space on one side of the piston 63 in the shell 61, so that the piston 63 moves. The water pump 10 is mounted on the housing 1, and the output end of the water pump 10 is connected to the connector 62 on the other side of the connecting mechanism 6 through another hose 8. The water bucket 9 is mounted on the housing 1, and the water bucket 9 is connected to the suction end of the water pump 10 through a hose. In this embodiment, the water pump 10 uses a BT100-1F peristaltic pump, which can accurately adjust the flow rate. The water bucket 9 is filled with nutrient solution. Turning on the water pump 10 can replenish the nutrient solution to the space on the other side of the piston 63 in the housing 61, thereby moving the piston 63 to the other side.

[0079] When the above mechanism is in use, the piston 63 is located in the middle of the housing 61. At this time, the two channels 65 and the two extension tubes 67 are staggered, and the channels of the extension tubes 67 are closed by the piston 63. When the air pump 7 is turned on to introduce air into the inner cavity of the housing 61 located on one side of the piston 63, the air pushes the piston 63 to move to the other side, stretching the spring 64 on the ventilation side and compressing the spring 64 on the other side. When the channel 65 on the ventilation side corresponds to the extension tube 67 on the ventilation side, the air is introduced into the culture compartment 401 in the incubator 4 to complete the aeration. During this process, the outer wall of the piston 63 completely closes the other extension tube 67. When the aeration work is finished, the air pump 7 is turned off, the air pressure in the ventilation side space is reduced, and the piston 63 is reset by the tension and elastic force of the spring 64. When the channel 65 is staggered with the extension tube 67 on the ventilation side, the extension tube 67 is immediately closed to prevent the nutrient solution from flowing back. When the water pump 10 is turned on to introduce nutrient solution into the other side of the inner cavity of the housing 61, the piston 63 can be moved to the other side according to the above principle, so that the passage of the extension tube 67 on the side of the supplementary nutrient solution is opened.

[0080] It is worth noting that in this embodiment, the cross-sectional shape of the piston 63 and the cross-sectional shape of the inner cavity of the housing 61 are prismatic, which can prevent the piston 63 from rotating relative to the housing 61.

[0081] The above structure can realize aeration work in the culture compartment 401 to ensure normal breathing of the rice roots, and can also add nutrient solution therein. At the same time, the setting of the piston 63 can accurately separate the spatial channels of the two to ensure that they do not affect each other; at the same time, under the action of the spring 64, it can be ensured that the piston 63 immediately closes the channel after completing the aeration or replenishing the nutrient solution work, thereby avoiding the nutrient solution in the culture compartment 401 from flowing back, thereby improving the accuracy and stability of the equipment; the maximum movement range of the piston 63 can also be limited by the action of the limit seat 66 to avoid the piston 63 from being misplaced.

[0082] like Figure 3 , Figure 4 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, the cultivation device further comprises a toggle mechanism 12 and a motor 13. The toggle mechanism 12 is installed in the cultivation chamber 3, and the toggle assembly 12 is used to toggle the seeds in the planting basket 5.

[0083] The toggle assembly 12 includes: a mounting plate 121, a first slide 122, a slide bar 123, a movable plate 124, a second slide 125, a slider 126, a paddle 127, a paddle 128, a reciprocating screw 129 and a protrusion 1210. The mounting plate 121 is installed in the culture chamber 3. The mounting plate 121 is located on the rear side of the incubator 4. There are two first slides 122, which are symmetrically opened on the mounting plate 121. The first slide 122 consists of two parts, namely, two parts of the slide that are inclined and horizontally set. The slide bar 123 is installed in the culture chamber 3. There are two movable plates 124, which are symmetrically arranged relative to the mounting plate 121. The movable plates 124 are slidably installed on the slide bar 123. The movable plates 124 can slide along the axial direction of the slide bar 123. At the same time, the cross-sectional shape of the slide bar 123 is a prism, which is adapted to the shape of the chamber where the movable plates 124 and the slide bar 123 are slidably connected, thereby ensuring that the movable plates 124 move stably and avoid self-rotation. The second slideway 125 is opened on the movable plate 124, and the second slideway 125 is vertically arranged along the up and down direction. The slider 126 is installed in the first slide 122 and the second slide 125, wherein a slot 1261 is provided on the slider 126, and the slot 1261 is engaged with the second slide 125. The limit cooperation between the slot 1261 and the second slide 125 can ensure that the slider 126 can only move in the up and down directions relative to the second slide 125, thereby avoiding rotation or shaking. A limit rod 1262 is provided on the side of the slider 126 away from the paddle 127, and the limit rod 1262 is slidably connected with the first slide 122, so that the slider 126 can be limited by the first slide 122 while being limited by the second slide 125. The paddle 127 is installed on the slider 126, and the position and width of the paddle 127 are adapted to the culture compartment 401 in the incubator 4. There are several pusher claws 128, which are respectively installed on the lower surface of the paddle 127. The pusher claws 128 are needle-shaped parts made of stainless steel, and the spacing between two adjacent pusher claws 128 is 5mm. The reciprocating screw 129 is rotatably installed in the culture chamber 3. The reciprocating screw 129 is provided with two mutually symmetrical spiral groove parts, which is an existing device. The protrusion 1210 is installed on the moving plate 124. The protrusion 1210 and the threaded part on the reciprocating screw 129 are slidably matched. When the reciprocating screw 129 rotates, the side of the spiral groove pushes the protrusion 1210 placed in the spiral groove to reciprocate along the axial direction of the reciprocating screw 129. In this embodiment, the length of the spiral groove part of the reciprocating screw 129 is adapted to the width of the culture compartment 401 along the axial direction of the reciprocating screw 129, ensuring that the moving distance of the moving plate 124 can cover the entire area range of the culture compartment 401. The motor 13 is mounted on the housing 1 , and the output end of the motor 13 extends into the culture chamber 3 and is connected to one end of the reciprocating screw 129 . Turning on the motor 13 can drive the reciprocating screw 129 to rotate.

[0084] The specific use process of the toggle assembly 12 is as follows: turn on the motor 13 to drive the reciprocating screw 129 to rotate, and use the cooperation of the reciprocating screw 129 and the protrusion 1210 to make the two movable plates 124 approach each other synchronously, and use the common limit of the first slide 122 and the second slide 125 to make the slider 126 move downward first, so that the claw 128 enters the planting basket 5 in the culture compartment 401, and then the slider 126 slides into the horizontal part of the first slide 122, and the paddle 127 and the claw 128 begin to move horizontally, and the seeds in the planting basket 5 begin to be toggled. As the protrusion 1210 reciprocates along the axial direction of the reciprocating screw 129, the rice seeds in the planting basket 5 can be toggled to ensure that the local temperature of the seeds will not rise during the germination stage.

[0085] The above mechanism can realize automatic shifting of rice seeds in the germination stage, avoid excessive local temperature caused by accumulation of rice seeds or long-term stillness, which affects the accurate determination of seed germination rate, and can also save labor costs and improve efficiency; in addition, by utilizing the design of the first slide 122, the claw 128 can firstly drop rapidly and then move laterally, and the same is true for its reset process, ensuring that the claw 128 will not stay in the planting basket 5 when not in use, avoiding the claw 128 from being infiltrated by nutrient solution for a long time and breeding bacteria, thereby preventing harm to rice seeds; the structure can fully realize the shifting of seeds and improve the efficiency of seed shifting by setting a plurality of claws 128 arranged closely at equal intervals, while the contact surface between the needle-shaped claw 128 and the rice seed is arc-shaped and has a very small surface area, which can only realize the shifting of rice seeds but will not push the rice seeds to move.

[0086] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
