Description

Technical Field

[0001] This application relates to the field of agricultural engineering technology, and in particular to a drainage structure suitable for chain-driven planting structures. Background Technology

[0002] Chain-driven planting structures are transmission systems used in agricultural planting machinery. They transmit power through the cooperation of chains and sprockets to drive the various components of the planting machinery to work in a coordinated manner. Their core feature is the utilization of the reliability and adaptability of chain drives to meet the operational needs of planting machinery in plant factories. Examples include the three-dimensional recirculating hydroponic container plant factory disclosed in announcement number CN220936091U and the solar-powered high-rise factory production line facility for forage, vegetables, flowers, and medicinal herbs disclosed in announcement number CN101743897A. Chain-driven planting structures allow planting troughs to move slowly and smoothly, thereby achieving automated cultivation, saving manpower, and ensuring uniform plant growth, avoiding marginal effects during plant growth.

[0003] However, in chain-driven planting systems, since the planting trough is always in motion, it is impossible to install a static drainage pipe like in a fixed planting system. Existing technology usually involves directly opening a hole at the bottom of the planting trough to allow the liquid inside to drip directly down.

[0004] If the liquid is a nutrient solution, it will drip directly onto the leaves of the lower plants, affecting their photosynthesis, or it will accumulate in other parts of the plant, affecting the growth of their roots and other parts. Utility Model Content

[0005] In order to achieve simple control of drainage in chain-driven planting, so that the planting trough does not drain when it is in the upper layer and drains when it is in the lower layer, this application provides a drainage structure suitable for chain-driven planting structures.

[0006] The drainage structure for chain-driven planting structures provided in this application adopts the following technical solution:

[0007] A drainage structure suitable for chain-driven planting structures includes a sealing plate, a connecting rod, a guide, and a resetting member, wherein the guide is connected to the connecting rod, and the connecting rod is connected to the sealing plate;

[0008] When the guide is subjected to an upward force from the outside, the connecting rod drives the sealing plate to separate from the drainage outlet of the planting trough, so that the liquid in the planting trough can be drained.

[0009] When the guide is removed by an upward force from the outside, the reset component controls the sealing plate, the guide and the connecting rod to reset, at which point the sealing plate seals the drainage outlet of the planting trough.

[0010] By adopting the above technical solution, a drainage structure with automatic control device opening and closing is provided. Dynamic drainage control is achieved through the linkage of guide members, connecting rods and sealing plates, so that the planting trough is completely sealed and does not drain when it is in the upper layer, and the sealing plate is opened under the action of external force when passing through the guide ramp at the lowest layer to drain water. The structure is simple and reliable and is suitable for chain drive planting systems.

[0011] Optionally, the reset component includes a reset spring and a mesh, the mesh being fixed to the bottom of the planting trough, the connecting rod passing through the mesh, one end of the reset spring being connected to the mesh, and the other end of the reset spring being connected to the guide component;

[0012] When the sealing plate separates from the drainage outlet of the planting trough, the return spring is in a compressed state;

[0013] When the sealing plate covers the drainage outlet of the planting trough, the reset spring is in its natural state.

[0014] By adopting the above technical solution, the reset component uses a combination of a reset spring and a mesh. The mesh is fixed to the bottom of the planting trough to support the reset spring. When the reset spring is compressed, it stores energy to achieve drainage. Under natural conditions, it resets and seals, ensuring precise opening and closing of the drainage outlet and enhancing structural controllability.

[0015] Optionally, a sealing plug is fixed at the drain outlet of the planting trough. The sealing plug is used to restrict the liquid from flowing out along the inner wall of the drain outlet of the planting trough. The connecting rod passes through the sealing plug, and a drain hole is opened on the sealing plug. When the guide is removed by an external upward force, the sealing plate seals the drain hole.

[0016] By adopting the above technical solution, a sealing plug is added at the drain outlet to limit liquid leakage along the inner wall and improve the sealing performance; while the drain hole opened on the sealing plug allows the liquid to drain normally; when the guide on the connecting rod is subjected to an external upward force, the sealing plate will open, and the liquid will be discharged through the drain hole on the sealing plug. After the force is removed, the sealing plate will automatically return to its original position to close the sealing plug. The upper layer of the planting trough can be completely sealed and the lower layer can be automatically drained without electricity or manual intervention. It has the characteristics of simple structure and high reliability.

[0017] Optionally, the number of drainage holes is several.

[0018] By adopting the above technical solution, the drainage holes are designed in multiple ways to improve drainage efficiency and disperse the liquid flow path, thus avoiding blockage of a single hole.

[0019] Optionally, the guide is fixed to the end of the connecting rod away from the sealing plate, and the guide is a sphere.

[0020] By adopting the above technical solution, the guide component adopts a spherical structure, which facilitates smooth contact with the guide ramp below the chain drive device, has high adaptability, reduces friction loss, and allows the sealing plate to be reset better.

[0021] Optionally, the return spring is a conical spring, which is sleeved on the connecting rod and connected to the top of the ball.

[0022] By adopting the above technical solution, the return spring adopts a conical design and is sleeved on the connecting rod, which saves space and prevents displacement. It is connected to the top of the ball so that it can better fit the top of the ball and ensure accurate reset.

[0023] Optionally, the connecting rod passes through the sealing plate, and the sealing plate is coaxially arranged with the connecting rod.

[0024] Optionally, the sealing plug has an annular groove along its outer circumference, and the sealing plug is engaged with the drain outlet at the bottom of the planting trough through the annular groove.

[0025] By adopting the above technical solution, the sealing plug is snapped into the drain outlet through an annular groove, which facilitates installation and maintenance, while enhancing the sealing performance and preventing liquid from seeping out from the gap between the plug body and the drain outlet.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. This structure utilizes the guide component to move up and down under the action of force to automatically trigger the drainage action. When the planting trough is in the upper layer, the sealing plate completely seals the drainage outlet under the action of gravity and the return spring to prevent liquid loss. When it moves to the lower layer, the guide component is subjected to an upward force from the outside, which drives the sealing plate to open through the connecting rod, realizing the discharge of liquid in the trough. The whole process can achieve complete sealing of the upper layer and automatic drainage of the lower layer of the planting trough without electricity or manual intervention.

[0028] 2. A conical spring is sleeved on the connecting rod, and a mesh plate is used for fixed support. This prevents the return spring from shifting and ensures a fast and smooth return action. At the same time, the coaxial design of the sealing plate and the connecting rod ensures uniform sealing force, effectively avoiding leakage problems and significantly improving system reliability.

[0029] 3. The annular groove precisely engages with the drain outlet, and the full-coverage sealing plate ensures a complete seal of the upper planting trough. Multiple drain holes ensure even drainage and prevent localized stagnation. The added mesh prevents the return spring from pushing out the sealing plug without obstructing liquid flow, further enhancing system stability.

[0030] 4. Compared to traditional methods requiring metal ball valves, this system boasts advantages such as simpler structure, easier installation, and greater adaptability. The combination of the sealing plug and mesh allows for quick and reliable sealing in various planting trough structures, avoiding the sealing difficulties and complex installation issues associated with the rigid structure of traditional ball valves. Especially for addressing the varying drainage needs when planting different plants, simply changing or adjusting the number and diameter of the drainage holes on the sealing plug allows for flexible adjustment of the discharge volume without requiring a complete valve body replacement, significantly improving the system's versatility and economy.

[0035] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0036] Example 1

[0037] Embodiment 1 of this application discloses a drainage structure suitable for chain-driven planting structures.

[0038] like Figure 1 and Figure 2 The drainage structure applicable to chain-driven planting structures includes a sealing plate 1, a connecting rod 2, a guide 4, and a reset component 5. The reset component 5 includes a reset spring 51 and a mesh 52. The mesh 52 is fixed to the bottom wall of the planting trough. A sealing plug 3 is fixed at the drainage outlet of the planting trough. In this embodiment, the sealing plug 3 is a silicone plug with several drainage holes 31 and an annular groove 32 on its outer circumference. The guide 4 is a sphere, which is integrally formed with the connecting rod 2. In this embodiment, a ball-head screw is used as the combination structure of the guide 4 and the connecting rod 2. The other end of the connecting rod 2 is welded to the sealing plate 1 to drive the movement of the sealing plate 1. In its natural state, the ball-head screw hangs down naturally, and the sealing plate 1 covers the sealing plug 3. The reset spring 51 is sleeved on the connecting rod 2, with the smaller diameter end welded to the mesh 52 and the larger diameter end connected to the top of the sphere of the guide 4.

[0039] In other embodiments, the connecting rod 2 can also be bolted to the sealing plate 1; the guide 4 can be various shapes such as conical or teardrop-shaped.

[0040] The implementation principle of this application embodiment is as follows: A guide ramp, such as a trapezoidal ramp, is placed directly below the lower planting trough of the chain-driven planting structure. When the planting trough runs to the guide ramp of the lower layer of the chain-driven planting structure, the guide 4 abuts against the guide ramp. As the planting trough gradually runs to the highest position of the guide ramp, the guide 4 is subjected to an upward force from the guide ramp, the return spring 51 is squeezed, and the connecting rod 2 pushes the sealing plate 1 to move upward gradually. At this time, the sealing plate 1 separates from the sealing plug 3, and all the small holes are exposed, so that the liquid in the planting trough can be discharged from the drain hole 31 on the sealing plug 3.

[0041] When the planting trough leaves the guide ramp, the force exerted by the guide ramp on the guide member 4 disappears. Under the action of its own gravity and the assistance of the elastic force of the return spring 51, the guide member 4 returns to its initial state. At this time, the sealing plate 1 driven by the connecting rod 2 also returns to the state of completely covering the drainage outlet. All drainage holes 31 are completely covered and the drainage outlet is sealed, so that the liquid in the planting trough cannot be discharged. This realizes the function of drainage in the lower horizontal conveying section of the chain-driven planting structure and stopping drainage in other transmission parts.

[0042] Compared to traditional methods that require the installation of metal ball valves, this system offers advantages such as simpler structure, easier installation, and greater adaptability. Through the cooperation of the sealing plug 3 and the mesh 52, rapid and reliable sealing installation is achieved in various planting trough structures, avoiding the sealing difficulties and complex installation problems associated with the rigid structure of traditional ball valves. Especially for the varying drainage needs when planting different plants, the drainage volume can be flexibly adjusted simply by changing or adjusting the number and diameter of the drainage holes 31 on the sealing plug 3, without requiring a complete replacement of the valve body, significantly improving the system's versatility and economy.

[0043] Example 2

[0044] Reference Figure 3 The difference between this embodiment and embodiment 1 is that the reset member 5 takes another form, that is, the mesh 52 is set above the sealing plug 3, the mesh 52 is welded to the inner bottom wall of the planting trough, and the size of the mesh 52 is smaller than the sealing plate 1, so it can be completely covered by the sealing plate 1; the smaller diameter end of the reset spring 51 is connected to the bottom of the sealing plug 3.

[0045] The implementation principle of Example 2 is as follows: the mesh 52 is placed above the sealing plug 3. The welding of the mesh 52 to the planting trough improves the stability of the entire device and prevents the silicone plug from being pushed up by the reset spring 51 during use.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
