Description

Technical Field

[0001] The invention relates to the technical field of cultivation devices, in particular to a seed cultivation device. Background Art

[0002] Wheat is one of the most important food crops in the world. It is widely planted in temperate regions and is mainly used to make flour, bread, biscuits and other foods. The growth cycle of wheat is divided into stages such as sowing, germination, jointing, heading, filling and maturity. It has strict requirements on the growth environment and is suitable for growing in warm and humid climates. In order to promote uniform germination and healthy growth of seeds, ensure the suitability of environmental conditions, and avoid the adverse effects of external climate change, it is necessary to use a cultivation device to cultivate seeds.

[0003] Publication No. (CN115104464A) discloses a seed cultivation device, including a cultivation box, the inner bottom wall of the cultivation box is provided with a forward and reverse motor, the forward and reverse motor is provided with one end of a rotating shaft, the other end of the rotating shaft contacts the inner top wall of the cultivation box, the rotating shaft is provided with multiple layers of stirring blades, the inner side wall of the cultivation box is provided with a plurality of cultivation plates along the height direction, all the cultivation plates are movably sleeved on the rotating shaft, the cultivation plates and the stirring blades are staggered, and the inner side wall of the cultivation box is provided with a heating plate. Through the cooperation of the heating plate and the stirring blades, the generated hot air is evenly distributed in the cultivation box, so that the seeds are heated evenly.

[0004] However, during the growth process of wheat, especially in the seedling and young stage, the root system will continue to expand, and sufficient space is needed to take root and absorb water and nutrients. During the use of the above-mentioned cultivation device, the planting space cannot be expanded, which will cause the root system to be restricted by space, resulting in root crowding, root entanglement or poor growth. When the root system is restricted, the wheat may not be able to effectively absorb water and nutrients from the soil, resulting in insufficient water or nutrients in the plant. Especially in the later stage of wheat growth, the plant's demand for water and nutrients increases, and the inability to fully expand the root system may lead to poor growth and affect yield and quality.

[0032] In the present invention, through the setting of the expansion mechanism 4, the size of the bottom space can be flexibly adjusted, avoiding the disadvantage of the root system being restricted in the traditional planting device. By rotating the turntable 402, the transmission rod 401 is driven to rotate, so that the transmission bevel gear 403, the connecting rod 404, the transmission gear 406 and the driven gear 407 are rotated, driving the threaded rod 408 to rotate, driving the folding cover 502 and the supporting plate 503 to extend downward, providing more expansion space for the root system, and effectively avoiding the crowding of the root system.

A limit block 409 is fixedly installed on the top of the threaded rod 408. The limit block 409 is made of rubber and has a circular shape. The diameter of the limit block 409 is larger than the diameter of the threaded hole 507, which is 1.0 times the diameter of the threaded rod 408, to ensure that the position of the carrier plate 503 can be accurately controlled when the threaded rod 408 rotates.

[0034] In the present invention, through the setting of the folding mechanism 5, the threaded rod 408 drives the supporting plate 503 to move downward through the action of the threaded connection during the rotation process. The supporting plate 503 moves and the folding cover 502 is driven to move downward at the same time, thereby stretching the folding cover 502. It can flexibly expand the bottom space according to the needs of different growth stages of wheat, avoid root restriction, and promote healthy root development. Secondly, providing more space helps to improve the absorption efficiency of water and nutrients and enhance the stress resistance of wheat, especially in drought or malnutrition environments, improve the activity of rhizosphere microorganisms, optimize the interaction between the root system and the soil, and improve the overall growth quality.

[0035] Specifically, the front side of the incubator 3 is movably connected to a door 6 via a hinge, and the top of the incubator 3 is movably connected to a cover plate 7 via a hinge. The cover plate 7 is made of transparent plastic material to facilitate observation of the growth of seeds in the incubator 3. Ventilation slots 8 are provided on the surface of the cover plate 7. The ventilation slots 8 are designed as a plurality of arc-shaped slender channels, and the ventilation slots 8 account for 40%-50% of the total surface area of ​​the cover plate 7, thereby ensuring air circulation inside the incubator 3 and maintaining suitable humidity and temperature. Universal wheels 9 are fixedly installed around the bottom of the base plate 1. The universal wheels 9 are made of wear-resistant material and can withstand a load of at least 50 kg. The four universal wheels 9 are each equipped with a set of self-locking devices. Through a simple manual switch operation, the rotation of the universal wheels 9 can be locked after they stop moving to prevent unnecessary movement during use.

[0036] In the present invention, through the provision of the cover plate 7, it is convenient to add soil, sow seeds, and water the inside of the cultivation box 3 after opening. The transparent design of the cover plate 7 allows the user to clearly observe the growth of seeds in the cultivation box 3, thereby facilitating timely management and adjustment. The provision of the ventilation slots 8 can ensure air circulation inside the cultivation box 3. The slender channel design of the ventilation slots 8 can effectively avoid the drastic impact of the external environment on the environment inside the cultivation box 3, adjust the humidity and temperature, and create a suitable plant growth environment. Through the provision of the universal wheel 9, the entire device can be easily moved to the desired position, and can be easily adjusted to both indoor and outdoor environments to adapt to different working scenes. In addition, the self-locking structure of the universal wheel 9 ensures that the entire device can be stably fixed when it does not need to be moved, prevents the device from sliding or tilting due to external force or improper operation, improves safety and stability during use, reduces the complexity of manual operation, and improves convenience of use.

[0037] The working principle of the present invention is as follows: after the device is moved to a suitable position by the universal wheel 9, the cover plate 7 is opened to place the soil into the planting box 501, the folding cover 502 and the carrying plate 503, and the soil is carried by the carrying plate 503. At this time, the wheat seeds can be sown in the soil. By setting the cover plate 7 and the ventilation slots 8, the air flow inside the cultivation box 3 can be ensured to provide a suitable growth environment for the seeds. When the seeds grow to the next stage, their roots extend downward and need to occupy more space, the turntable 402 can be rotated to drive the transmission rod 401 to rotate. The transmission rod 401 drives the transmission bevel gear 403 to rotate during the rotation process. At this time, the driven bevel gear 405 is driven to rotate under the action of the meshing of the teeth, and the driven bevel gear 405 drives the connecting rod 403 to rotate during the rotation. 4 is rotated, and the rotation of the connecting rod 404 drives the transmission gear 406 fixedly connected to its surface to rotate, so that the driven gear 407 rotates with the transmission gear 406 under the action of tooth meshing, and the rotation of the driven gear 407 drives the threaded rod 408 to rotate. During the rotation, the threaded rod 408 drives the supporting plate 503 to move downward under the action of the threaded connection. The movement of the supporting plate 503 drives the folding cover 502 to move downward, thereby stretching the folding cover 502 to extend and expand it, providing more space for the rhizome. During the planting period, the excess water in the soil will be discharged through the drainage hole 506 and accumulated in the water storage pipe 504. When it is necessary to take out the water, the box door 6 can be opened, and the sealing cover 505 can be rotated to remove the water.
