[0001] The utility model relates to the field of rice planting, in particular to the field of rice seedling cultivation, and in particular to a rice seedling cultivation device for preventing seeds from decaying. Background Art

[0002] Rice is one of the staple foods in my country. When planting rice, it is first necessary to cultivate seedlings, that is, raise them. After the seedlings grow for a period of time, they are transplanted into farmland. During the raising process, too much water in the soil will cause root rot of the seedlings, and too little water in the soil will affect the growth of the seedlings. In addition, the different growth stages of the seedlings have different requirements for soil moisture content. Based on this, the utility model proposes a rice seedling raising device that prevents seed rot. Utility Model Content

[0003] In order to solve the problems mentioned in the above background, the utility model provides a rice seedling raising device that prevents seeds from decaying.

[0004] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows.

[0005] A rice seedling raising device for preventing seed decay comprises a water trough in which water is stored. A plurality of rice seedling raising components for raising rice seedlings are arranged in an array in the water trough. The rice seedling raising components can automatically replenish water or stop replenishing water according to the moisture content of the soil inside the components.

[0006] As a further improvement and optimization of the present invention, the seedling raising assembly includes an outer fixed cylinder shell with a vertically arranged axis, an open upper end and a closed lower end. An inner floating cylinder shell is coaxially sleeved inside the outer fixed cylinder shell. A spring is arranged between the inner floating cylinder shell and the bottom of the outer fixed cylinder shell. A seedling raising cylinder shell is placed inside the inner floating cylinder shell. The seedling raising cylinder shell stores soil and rice seeds, and a plurality of fine holes are distributed in an array on the outer surface of the seedling raising cylinder shell.

[0007] As a further improvement and optimization of the present invention, the outer circular surface of the outer fixed cylinder shell is provided with an outer water inlet hole, and the outer circular surface of the inner floating cylinder shell is provided with an inner water inlet hole. During the movement of the inner floating cylinder shell along the axial direction, the inner water inlet hole can be connected with the outer water inlet hole.

[0008] As a further improvement and optimization of the present invention, the outer diameter of the seedling raising cylinder shell is smaller than the inner diameter of the inner floating cylinder shell.

[0009] As a further improvement and optimization of the present invention, a plurality of external water inlet holes are provided and the heights of the plurality of external water inlet holes are different from each other.

[0010] As a further improvement and optimization of the present invention, a support seat is provided inside the outer fixed cylindrical shell, a spring is arranged between the support seat and the shell bottom of the outer fixed cylindrical shell, and the inner floating cylindrical shell is provided inside the outer fixed cylindrical shell and supported by the support seat.

[0011] As a further improvement and optimization of the present invention, a slot is provided at the upper end of the outer fixed cylinder shell, and the slot is located directly above the outer water inlet hole. There are several corresponding slots, and a lug is extended from the upper end of the inner floating cylinder shell, and a socket is provided on the lug. During the rotation of the inner floating cylinder shell, when the position of the inner water inlet hole matches the corresponding outer water inlet hole, the slot located directly above the outer water inlet hole is coaxial with the socket, and a rod is inserted between the socket and the slot.

[0012] As a further improvement and optimization of the present invention, a connecting air groove is provided on the inner wall of the external fixed cylindrical shell, the connecting air groove is close to the shell bottom of the external fixed cylindrical shell, and a connecting air hole communicating with the connecting air groove is provided on the upper end of the external fixed cylindrical shell.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] When the present application is used, when the moisture content in the soil is lower than the preset requirement, the weight of the inner floating cylinder shell and the seedling raising cylinder shell will decrease accordingly, and the spring releases the elastic force to drive the inner floating cylinder shell and the seedling raising cylinder shell to move upward, thereby connecting the inner water inlet hole with the outer water inlet hole, and the water in the water tank flows into the inner floating cylinder shell through the outer water inlet hole and the inner water inlet hole, thereby replenishing water. When the moisture content in the soil is replenished to meet the preset requirement, the weight of the inner floating cylinder shell and the seedling raising cylinder shell will increase accordingly, and the inner floating cylinder shell and the seedling raising cylinder shell will move downward, the inner water inlet hole and the outer water inlet hole will be disconnected, and the water replenishment will be interrupted. In this way, the purpose of automatic water replenishment is achieved, so that the seedlings are in a soil environment with moderate moisture content, thereby preventing the seedlings from root rot or poor development.

[0015] Furthermore, the soil moisture requirements for seedlings at different growth stages are different. The present application can solve this problem by rotating the inner floating shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0025] Reference Figures 1-6 A rice seedling raising device for preventing seed decay includes a water trough 1, in which water is stored. Several groups of rice seedling raising components for raising rice seedlings are arranged in an array in the water trough 1. The rice seedling raising components can automatically replenish water or stop replenishing water according to the moisture content in the soil inside the components. Example

[0026] Reference Figure 2-Figure 4 The seedling raising assembly includes an outer fixed cylinder shell 2 with a vertically arranged axis, an open upper end and a closed lower end. An inner floating cylinder shell 3 is coaxially sleeved inside the outer fixed cylinder shell 2, and a spring 5 is arranged between the inner floating cylinder shell 3 and the bottom of the outer fixed cylinder shell 2.

[0027] The outer circular surface of the outer fixed shell 2 is provided with an outer water inlet hole 201, and the outer circular surface of the inner floating shell 3 is provided with an inner water inlet hole 301. When the inner floating shell 3 moves along the axial direction, the inner water inlet hole 301 can be connected with the outer water inlet hole 201.

[0028] A seedling raising shell 4 is placed inside the inner floating shell 3 , and the seedling raising shell 4 stores soil and rice seeds as a seedling raising vessel.

[0029] When in use, the seedling raising shell 4 filled with soil and rice seeds is placed in the inner floating shell 3. The outer diameter of the seedling raising shell 4 is smaller than the inner diameter of the inner floating shell 3. There is a gap between the two. The inner floating shell 3 and the seedling raising shell 4 are supported by the spring 5.

[0030] When the water content in the soil is lower than the preset requirement, the weight of the inner floating cylinder shell 3 and the seedling raising cylinder shell 4 is reduced accordingly, and the spring 5 releases the elastic force to drive the inner floating cylinder shell 3 and the seedling raising cylinder shell 4 to move upward, so that the inner water inlet hole 301 can be connected with the outer water inlet hole 201, and the water in the water tank 1 flows into the inner floating cylinder shell 3 through the outer water inlet hole 201 and the inner water inlet hole 301. There are a number of fine holes distributed in an array on the outer surface of the seedling raising cylinder shell 4. The water in the inner floating cylinder shell 3 seeps into the seedling raising cylinder shell 4 through the fine holes, thereby replenishing water.

[0031] When the moisture content in the soil reaches the preset requirement, the weight of the inner floating shell 3 and the seedling raising shell 4 increases accordingly. Therefore, the inner floating shell 3 and the seedling raising shell 4 will move downward, the compression amount of the spring 5 increases, the inner water inlet hole 301 is disconnected from the outer water inlet hole 201, and the water replenishment is interrupted;

[0032] In this way, the purpose of automatic water replenishment is achieved, and the seedlings are placed in a soil environment with moderate moisture.

[0033] In the preferred embodiment, since the outer wall of the inner floating shell 3 needs to fit with the inner wall of the outer fixed shell 2, during the water replenishment process, the air in the area where the spring 5 is located is difficult to communicate with the outside world, thereby limiting the up and down movement of the inner floating shell 3 and the seedling raising shell 4. In order to solve this problem, refer to Figure 4 The inner wall of the outer fixed cylinder shell 2 is provided with a connecting air groove 202, and the connecting air groove 202 is close to the bottom of the outer fixed cylinder shell 2. The upper end of the outer fixed cylinder shell 2 is provided with a connecting air hole 203 which is connected to the connecting air groove 202. Through the cooperation of the connecting air hole 203 and the connecting air groove 202, the connection between the area where the spring 5 is located and the outside world is realized, so that the up and down movement of the inner floating cylinder shell 3 and the rice seedling cylinder shell 4 is unrestricted. Example

[0034] Reference Figure 5 and Figure 6 , there are multiple external water inlet holes 201 and the heights of the multiple external water inlet holes 201 are different. The significance of this is that, as can be seen from the description of the above embodiment one, when the soil moisture content is lower than the preset requirement, the inner floating cylinder shell 3 and the seedling raising cylinder shell 4 move upward, so that the inner water inlet hole 301 is connected with the outer water inlet hole 201 to achieve the purpose of water replenishment. Therefore, the height of the outer water inlet hole 201 is equivalent to the preset soil moisture requirement. Therefore, by setting multiple external water inlet holes 201 with different heights, by rotating the inner floating cylinder shell 3, the inner water inlet hole 301 is made to correspond to different external water inlet holes 201, thereby changing the preset soil moisture requirement. Since the soil moisture requirements required for different growth stages of seedlings are different, this problem can be solved by rotating the inner floating cylinder shell 3.

[0035] Further, refer to Figure 6A support seat 7 is provided inside the outer fixed cylinder shell 2, and the spring 5 is arranged between the support seat 7 and the bottom of the outer fixed cylinder shell 2. The inner floating cylinder shell 3 is arranged inside the outer fixed cylinder shell 2 and supported by the support seat 7. The significance of this is that since the inner floating cylinder shell 3 needs to rotate, a support seat 7 is provided to make corresponding improvements to the installation of the spring 5.

[0036] Further, refer to Figure 5 , the upper end of the outer fixed shell 2 is provided with a slot 204, and the slot 204 is located just above the outer water inlet 201. There are several corresponding slots 204. The upper end of the inner floating shell 3 is extended with a lug 302, and the lug 302 is provided with a socket. During the rotation of the inner floating shell 3, the socket can be coaxial with the slot 204. In addition, a plug rod 6 is inserted between the socket and the slot 204. Its significance is that the inner floating shell 3 is rotated so that the inner water inlet 301 matches the corresponding outer water inlet 201. At the same time, the outer water inlet 201 is located at this The slot 204 directly above 201 is coaxial with the socket, and the insertion rod 6 is inserted into the socket and the slot 204. On the one hand, the setting of the socket and the slot 204 can serve as an identifier, allowing the user to know which outer water inlet hole 201 corresponds to the inner water inlet hole 301. On the other hand, after adjustment, the guiding effect of the insertion rod 6 limits the inner floating shell 3 to move only in the vertical direction, so as to prevent the inner floating shell 3 from being accidentally touched and causing rotation, and the position of the inner water inlet hole 301 is changed, thereby affecting the water replenishment effect.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention.
