Description

Technical Field

[0001] The invention relates to the technical field of seed incubators, in particular to a seed incubator for agricultural biological research and development. Background Art

[0002] Seed incubator for agricultural biological research and development is a device used for indoor seed cultivation. It provides ideal temperature, humidity and light conditions for seeds to promote seed growth and germination. This incubator is usually composed of a system with temperature and humidity control functions to ensure that seeds grow quickly in a suitable environment. Seed incubator plays an important role in agricultural scientific research and variety improvement. It can accelerate the seed growth cycle and improve the harvest and crop quality.

[0003] Seed incubators need to be suitable for the cultivation of seeds of different crops. When irrigating different crops, the irrigation cycle and irrigation amount are different. When the irrigation amount is large, soil caking is prone to occur. Excessive watering will impact the soil surface, causing clay particles (diameter <0.002mm) and powder particles (0.002-0.05mm) to migrate downward with the water flow, filling large pores (diameter >0.1mm). After drying, a dense hard shell is formed, which can easily lead to root rot.

[0004] However, some seed incubators currently available are not convenient for timely detection and resolution of the problem of soil hardening in the incubator, which results in a low germination rate of crop seeds. To this end, we propose a seed incubator for agricultural biological research and development to solve the above problem. Summary of the invention

When the soil is soft, the resistance of the detection block to the soil is small, and the relative sliding distance of the detection block is small.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0030] Example

[0031] See also Figure 1-8 The present invention provides a technical solution: a seed culture box for agricultural biological research and development, comprising a box body 1, a box door 2 is arranged on the front side of the box body 1, the box door 2 is set to be transparent, a breeding basin 3 is arranged inside the box body 1, the breeding basin 3 is slidably connected to the inner wall of the box body 1 through a slide rail 4, and a drip irrigation mechanism with adjustable height is arranged inside the box body 1;

[0032] The drip irrigation mechanism includes a water tank 5 and an electric push rod 6. The water tank 5 is fixedly connected to the top of the box body 1. The movable end of the electric push rod 6 is fixedly connected to an iron mounting plate 7. A shunt pipe 8 is provided at the bottom of the iron mounting plate 7. A connecting pipe 9 is connected to the left side of the water tank 5. The connecting pipe 9 extends into the box body 1 and is connected to the shunt pipe 8 through a hose 10. A plurality of drip irrigation ports are provided at the bottom of the shunt pipe 8 to achieve dripping of irrigation water.

[0033] A detection mechanism for detecting soil hardening is provided at the bottom of the iron mounting plate 7. The detection mechanism includes a radio motor 11. A detection rod 12 is fixedly connected to the output shaft end of the radio motor 11. A pointed portion 16 is provided at the bottom end of the detection rod 12. A detection block 13 is slidably connected to the outer side of the detection rod 12. A spring 27 is provided between the detection block 13 and the radio motor 11. The spring 27 is movably sleeved on the outer side of the detection rod 12. A sliding distance sensor 20 is provided at the sliding connection between the detection block 13 and the detection rod 12. The detection rod 12 is driven by the electric push rod 6 to be inserted into the soil. The detection block 13 is subjected to resistance from the soil so that the detection block 13 slides upward relative to the detection rod 12. When the soil is soft, the detection block 13 is subjected to little resistance from the soil, and the relative sliding distance of the detection block 13 is small. After the soil is hardened, the detection block 13 is subjected to great resistance, and the relative sliding distance of the detection block 13 is large, thereby realizing the determination of the degree of soil hardening through the sliding distance sensor 20.

[0034] When it is necessary to irrigate the seeds in the breeding pot 3, the electric push rod 6 drives the iron mounting plate 7 and the shunt pipe 8 to move downward to the top of the soil. According to the type of crops planted, an appropriate amount of irrigation water is added to the water tank 5. The irrigation water passes through the connecting pipe 9 and the hose 10 and then through the several drip irrigation ports at the bottom of the shunt pipe 8 to drip irrigate the seeds. When the seeds sprout and break through the soil, the descending height of the electric push rod 6 is appropriately adjusted according to the height of the crop. The carbon dioxide generator 26 actively generates carbon dioxide to provide photosynthesis for the crop. When it is necessary to regularly test the hardness of the soil in the breeding pot 3, the magnetic block 25 on the top of the radio motor 11 is installed at the bottom of the iron mounting plate 7, and the electric push rod 6 is started. The electric push rod 6 drives the detection rod 12 to move downward, and the flexible rope 19 moves downward accordingly. When the soil is relatively soft, the detection block 13 is less resisted by the soil, and the reaction of the spring 27 is Under the application of force, the detection block 13 and the detection rod 12 remain relatively still and move downward synchronously. When the soil forms a hard lump, the resistance of the soil on the detection block 13 is greater than the reaction force of the spring 27, and the detection block 13 slides upward relative to the detection rod 12. The sliding distance sensor 20 measures the relative sliding distance. When the relative sliding distance exceeds a certain threshold, the sliding distance sensor 20 controls the radio motor 11 to rotate, and the radio motor 11 drives the detection rod 12 to rotate, thereby driving the flexible rope 19 to rotate. The centrifugal force generated makes the flexible rope 19 keep swinging in the horizontal direction, and the hardened soil blocks are whipped and broken up by the metal ball. After the soil blocks are broken up, the detection block 13 and the detection rod 12 continue to move downward synchronously until the humidity sensor 24 at the bottom of the pointed head 16 contacts the bottom of the breeding pot 3, and then rises. The humidity sensor 24 can measure the humidity of each soil layer, which is convenient for adjusting the total amount of irrigation.

[0035] In this embodiment, specifically: the first curved portion 14 and the second curved portion 15 are respectively provided on the upper and lower sides of the detection block 13, and the first curved portion 14 is used to reduce the resistance of the detection block 13 when buried in the soil, thereby avoiding the problem that too much invalid sliding caused by large resistance affects the detection accuracy, and the second curved portion 15 is used to reduce the resistance of the detection block 13 when unearthed, thereby avoiding the detection block 13 from bringing out soil when unearthed;

[0036] In this embodiment, specifically: a breaking mechanism for processing hardened soil blocks is provided inside the detection block 13, and the breaking mechanism includes a wire storage box 17, which is provided inside the detection block 13, and the wire storage box 17 is rotatably connected to a wire take-up roller 18, and a flexible rope 19 is wound around the outer side of the wire take-up roller 18, and the other end of the flexible rope 19 passes through the wire storage box 17 and the detection block 13 in turn and is fixedly connected to a metal ball, and the flexible rope 19 is slidably connected to the wire storage box 17 and the detection block 13, and when the soil blocks are hardened, the sliding distance sensor 20 measures that the relative sliding distance exceeds a certain threshold value, and controls the radio motor 11 to drive the detection rod 12 to rotate, thereby driving multiple flexible ropes 19 to swing to whip and break up the hardened soil blocks;

[0037] In this embodiment, specifically: the outer side of the wire storage box 17 is connected to two pressing plates 21 by hinge rotation, and the two pressing plates 21 are in close contact with the outer side of the flexible rope 19. A torsion spring 22 is provided between the pressing plate 21 and the wire storage box 17. The clamping force provided by the torsion spring 22 increases the friction between the pressing plate 21 and the flexible rope 19. A friction plate 23 is provided on the side where the two pressing plates 21 are close to each other. The friction with the flexible rope 19 is further increased by the provided friction plate 23. When the wear length of the distal end of the flexible rope 19 is reduced, the flexible rope 19 can be stretched outward by external force to compensate;

[0038] In this embodiment, specifically: a magnetic block 25 is fixedly connected to the top of the radio 11, and the radio 11 is freely installed and fixed with the iron mounting plate 7 through the magnetic block 25;

[0039] In this embodiment, specifically: a humidity sensor 24 is provided at the bottom of the pointed portion 16, and the humidity sensor 24 can measure the humidity of each soil layer to facilitate adjustment of the total amount of irrigation;

[0040] In this embodiment, specifically: a carbon dioxide generator 26 is arranged at the bottom of the box 1, and two air inlets of the carbon dioxide generator 26 are connected to the outside atmosphere through air inlet pipes. The carbon dioxide generator 26 generates more carbon dioxide for plant photosynthesis through operation.

[0041] The present invention is in operation: when in use, when it is necessary to irrigate the seeds in the breeding pot 3, the electric push rod 6 drives the iron mounting plate 7 and the shunt pipe 8 to move downward to the top of the soil, and an appropriate amount of irrigation water is added to the water tank 5 according to the type of crops to be planted. The irrigation water passes through the connecting pipe 9 and the hose 10 and then through the plurality of drip irrigation ports at the bottom of the shunt pipe 8 to drip irrigate the seeds. When the seeds sprout and break through the soil, the descending height of the electric push rod 6 is appropriately adjusted according to the height of the crop, and the carbon dioxide generator 26 actively generates carbon dioxide to provide photosynthesis for the crop. When it is necessary to regularly test the hardness of the soil in the breeding pot 3, the magnetic block 25 on the top of the radio motor 11 is installed at the bottom of the iron mounting plate 7, and the electric push rod 6 is started. The electric push rod 6 drives the detection rod 12 to move downward, and the flexible rope 19 moves downward accordingly. When the soil is relatively soft, the detection block 13 is less resisted by the soil, and the detection block 13 is elastic. Under the reaction force of the spring 27, the detection block 13 and the detection rod 12 remain relatively still and move downward synchronously. When the soil forms a hard lump, the resistance of the soil on the detection block 13 is greater than the reaction force of the spring 27, and the detection block 13 slides upward relative to the detection rod 12. The sliding distance sensor 20 measures the relative sliding distance. When the relative sliding distance exceeds a certain threshold, the sliding distance sensor 20 controls the radio motor 11 to rotate, and the radio motor 11 drives the detection rod 12 to rotate, thereby driving the flexible rope 19 to rotate. The centrifugal force generated makes the flexible rope 19 keep swinging in the horizontal direction, and the hardened soil blocks are whipped and broken up by the metal ball. After the soil blocks are broken up, the detection block 13 and the detection rod 12 continue to move downward synchronously until the humidity sensor 24 at the bottom of the pointed head 16 contacts the bottom of the breeding pot 3, and then rises. The humidity sensor 24 can measure the humidity of each soil layer, which is convenient for adjusting the total amount of irrigation.

The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the electric push rod 6, the radio motor 11, the sliding distance sensor 20, the humidity sensor 24 and the carbon dioxide generator 26 are no longer explained in detail.
