Description

Technical Field

[0001] The present invention relates to the technical field of storage tanks, and particularly to an integrated soil fertilizer storage tank. Background Art

[0002] A soil fertilizer storage tank generally refers to a container for storing soil conditioners or fertilizers. It is generally used in agriculture or horticulture to effectively store and manage soil conditioners (such as organic fertilizers, chemical fertilizers, etc.), ensuring that fertilizers and soil improvement materials are not affected by the external environment, such as moisture, weathering, etc., and maintaining their effectiveness and use safety. Specifically, a soil fertilizer storage tank has the following main functions: protecting fertilizers from moisture and weather changes, preventing fertilizers from caking or becoming ineffective; being suitable for storing a large amount of fertilizers or soil conditioners, especially suitable for large-scale agriculture or horticulture; facilitating users to extract fertilizers, and usually designed with a structure that is convenient for feeding and taking.

[0003] In the patent with the publication number CN115557109A, an organic fertilizer storage tank is disclosed, which includes a bottom, a tank body, a cover body, a connecting body, a heat exchange structure, and a heat exchange plate sealing structure. The tank body and the connecting body are assembled between the bottom and the cover body, the connecting body is assembled between adjacent tank bodies, the side wall of the tank body is penetrated and assembled with the heat exchange structure, and the heat exchange plate sealing structure is assembled at the outer end of the heat exchange structure. The storage tank of the present invention is assembled by splicing the bottom, the tank body, the cover body, and the connecting body, and a heat exchange structure is also provided, which can realize the drying work of the organic fertilizer in the storage tank by filling high-temperature dry air, and bring the water vapor to the cover body to be absorbed by the water-absorbing material, so as to adjust the humidity in the storage tank and realize the dehumidification work. After the heat exchange structure is sealed by using the heat exchange plate sealing structure, the heat exchange plate can effectively dissipate the heat inside the organic fertilizer.

[0004] The prior art has the following defects: First of all, the existing soil fertilizer storage tanks often adopt a vertical ventilation duct ventilation design, and this vertical duct cannot provide good ventilation for the soil fertilizer at all positions. Since the stored soil fertilizer materials will release a certain amount of moisture during long-term storage, if the ventilation is not smooth, a humid environment is likely to be generated inside the tank body, resulting in caking, mildew of the materials, and even the generation of harmful gases, affecting the quality and storage safety of the soil fertilizer. In addition, the humid environment may also cause corrosion of the storage tank and shorten the service life of the tank body.

[0005] Secondly, the heat accumulation in local areas inside the soil fertilizer storage tank is also a prominent problem. Due to the lack of effective heat dissipation and ventilation measures, the temperature inside the tank body may be too high. Especially in summer with high temperatures, local heat accumulation may not only accelerate the aging of the soil fertilizer, but also lead to the unevenness of the stored materials, affecting their use effects. Summary of the Invention

[0006] In view of the above problems in the prior art, a soil-fertilizer integrated storage tank is proposed.

[0007] This application provides a soil-fertilizer integrated storage tank, and its purpose is to solve the problem that the center of the storage tank accumulates heat when storing soil fertilizer, and it is difficult for the ventilation pipe to evenly dissipate heat inside the soil fertilizer.

[0008] The technical solution of the present invention is: a soil-fertilizer integrated storage tank, including a tank body. A central rod is arranged through the center line of the tank body. A spiral groove is arranged on the outer periphery of the central rod. A plurality of sleeves are nested in sequence from the outside to the inside. The outermost sleeve is fixed at the top of the tank body. A rotating pipe is arranged inside the innermost sleeve. The bottom of the rotating pipe is connected to the bottom of the innermost sleeve. Spiral threads are arranged on the inner wall of the rotating pipe, and the spiral threads slide in the spiral groove. A pair of guide columns are vertically arranged between the rotating pipe and the innermost sleeve. The upper ends of the pair of guide columns are jointly connected to a first turntable, and the lower ends are jointly connected to a second turntable. The first turntable is rotatably arranged at the upper opening of the outermost sleeve, and the second turntable is rotatably arranged at the bottom of the tank body. A ventilation pipe is arranged on the outer periphery of the innermost sleeve, and the ventilation pipe is communicated with the inner cavity of the innermost sleeve. Exhaust holes are equidistantly distributed on the ventilation pipe; It also includes a gas supply component, which is connected to the inner cavity of the sleeve and is used to supply gas to the ventilation pipe; A driving component, which is connected to the first turntable and is used to drive the pair of guide columns to rotate; When the pair of guide columns rotate, they drive the innermost sleeve to rotate and move down along the spiral groove on the central rod, so that the ventilation pipe connected to the innermost sleeve rotates and moves down synchronously.

[0009] By adopting the above scheme, by setting a rotating and vertically displaced ventilation pipe, the areas with higher temperature and lower temperature can be effectively mixed, avoiding the phenomenon of temperature accumulation and reducing the risk of overheating. This helps to maintain the uniformity of the temperature inside the soil fertilizer, thereby reducing the impact of temperature fluctuations on the quality of the soil fertilizer; when the pipe rotates, it can enter the inside of the soil fertilizer and directly dissipate heat from the heat accumulation area to ensure that the heat is dissipated in time and prevent the soil fertilizer from spoiling or losing its nutritional value due to excessive temperature; through the rotating pipe, not only can the ventilation be improved, but also the soil fertilizer can be turned, promoting the air exchange inside and outside the soil fertilizer, accelerating the decomposition process of organic matter, and at the same time preventing uneven accumulation or lack of air in some areas for a long time, avoiding problems such as piled-up spoilage.

[0010] Further, the ventilation pipe includes an arc section and a conical spiral section. The arc section and the conical spiral section are hollow and communicated inside, and the connection between the arc section and the conical spiral section is sharp.

[0011] With the above solution, by setting the ventilation pipe as a conical spiral shape, the air circulation path can be optimized, the air flow resistance can be reduced, and the ventilation effect can be enhanced; this helps to evenly distribute the air flow in the tank, avoid lack of ventilation or moisture accumulation in local areas, and thus improve the air circulation efficiency of the storage environment; the conical design makes the air flow path more uniform in the diameter direction of the tank body, and at the same time, the conical spiral ventilation pipe has less resistance when rotating downward and penetrating into the soil fertilizer.

[0012] Furthermore, the cross-section of the ventilation pipe is fusiform.

[0013] With the above solution, by making the cross-section of the ventilation pipe fusiform, the resistance when the ventilation pipe penetrates into the soil fertilizer is reduced.

[0014] Furthermore, the conical slope of the conical spiral section is 55° - 60°.

[0015] With the above solution, by controlling the conical slope of the conical spiral section to be 55° - 60°, the inclination angle of the conical spiral ventilation pipe is smaller and the resistance is smaller when rotating downward and penetrating into the soil fertilizer.

[0016] Furthermore, an elastic pore membrane is provided at the exhaust hole, and slits are formed on the elastic pore membrane.

[0017] With the above solution, by providing the elastic pore membrane, dust is prevented from entering the exhaust hole.

[0018] Furthermore, the driving assembly includes a driving motor provided at the top of the tank body, a first pulley provided on the main shaft of the driving motor, a second pulley sleeved on the top of the central rod and connected to the first turntable, and the first pulley and the second pulley are connected by a transmission belt.

[0019] With the above solution, by providing the driving assembly, it is used to drive a pair of guide columns to rotate, and further drive the ventilation pipe to rotate downward.

[0020] Furthermore, the air supply assembly includes an air supply chamber provided at the upper end of the central rod, an air inlet hole provided on the air supply chamber, the air inlet hole communicating with the inner cavity of the sleeve, and an air inlet pipe connected to the top of the central rod.

[0021] With the above solution, through the air supply assembly, air enters the ventilation pipe through the sleeve to ventilate the center of the soil fertilizer.

[0022] Furthermore, a feed inlet is provided at the top of the tank body, and a discharge outlet is provided at the bottom of the tank body.

[0023] With the above solution, by providing the feed inlet and the discharge outlet, it is used to feed and discharge materials into the tank body.

[0024] The beneficial effects of the present invention: By setting up a ventilation pipe that rotates and has a vertical displacement, it is possible to effectively mix the areas with higher temperatures and lower temperatures, avoid the phenomenon of heat accumulation, reduce the risk of overheating, which helps to maintain the uniformity of the temperature inside the soil fertilizer, thereby reducing the impact of temperature fluctuations on the quality of the soil fertilizer; when the pipe rotates, it can enter the interior of the soil fertilizer and directly dissipate heat from the heat accumulation area to ensure that the heat is dissipated in a timely manner and prevent the soil fertilizer from spoiling or losing its nutritional value due to excessive temperature; through the rotating pipe, not only can ventilation be improved, but it can also play a role in turning the soil fertilizer, promoting the air exchange inside and outside the soil fertilizer, accelerating the decomposition process of organic matter, and at the same time preventing uneven accumulation or long-term lack of air in certain areas and avoiding problems such as piled-up spoilage.

[0025] By setting the ventilation pipe in a conical spiral shape, the air flow path can be optimized, the air flow resistance can be reduced, and the ventilation effect can be enhanced; this helps to evenly distribute the air flow in the tank, avoid lack of ventilation or accumulation of moisture in local areas, thereby improving the air circulation efficiency of the storage environment; the conical design makes the air flow path more uniform in the diameter direction of the tank body, and at the same time, the resistance of the conical spiral ventilation pipe when penetrating into the soil fertilizer when rotating downward is smaller.

[0028] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following provides a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings of the specification.

[0029] Example, referring to Figure 1-7 , which is an embodiment of the present invention, provides a soil-fertilizer integrated storage tank, including a tank body 1. A central rod 2 is disposed through the center line of the tank body 1. A spiral groove 3 is provided on the outer periphery of the central rod 2. A plurality of sleeves 4 are nested in sequence from outside to inside. The outermost sleeve 4 is fixed to the top of the tank body 1. A rotating tube 5 is provided inside the innermost sleeve 4. The bottom of the rotating tube 5 is connected to the bottom of the innermost sleeve 4. A spiral thread 6 is provided on the inner wall of the rotating tube 5. The spiral thread 6 slides in the spiral groove 3. A pair of guide columns 7 are vertically penetrated between the rotating tube 5 and the innermost sleeve 4. The upper ends of the pair of guide columns 7 are commonly connected to a first turntable 8, and the lower ends are commonly connected to a second turntable 9. The first turntable 8 is rotatably disposed at the upper opening of the outermost sleeve 4. The second turntable 9 is rotatably disposed at the bottom of the tank body 1. A ventilation pipe 10 is provided on the outer periphery of the innermost sleeve 4. The ventilation pipe 10 is communicated with the inner cavity of the innermost sleeve 4. Exhaust holes 11 are equally spaced on the ventilation pipe 10; further includes a gas supply assembly connected to the inner cavity of the sleeve 4 for supplying gas to the ventilation pipe 10; a driving assembly connected to the first turntable 8 for driving the pair of guide columns 7 to rotate; when the pair of guide columns 7 rotate, the innermost sleeve 4 is driven to rotate and move downward along the spiral groove 3 on the central rod 2, so that the ventilation pipe 10 connected to the innermost sleeve 4 rotates and moves downward synchronously.

[0030] In this embodiment, 5 sleeves 4 are provided. The 5 sleeves 4 nested in sequence are used to ventilate the ventilation pipe 10 spiraling downward. Symmetrical convex rings are provided at the upper and lower ends of each sleeve 4 to prevent adjacent rings from becoming loose during the extension and retraction of the multiple sleeves 4. It can be understood that the number of sleeves 4 is not limited, and the minimum is 2, which can be increased or decreased according to the size of the tank body 1. When driving the pair of guide columns 7 to rotate, a sliding occurs between the connection of the rotating tube 5 and the innermost sleeve 4 and the pair of guide columns 7. The lower end surface of the connection of the rotating tube 5 and the innermost sleeve 4 is set to be arc-shaped to reduce the resistance of the innermost sleeve 4 when penetrating into the fertilizer layer downward. The second turntable 9 is rotatably disposed in the bearing seat at the bottom of the tank body 1, so that the second turntable 9 is restricted to rotate within the bearing seat.

[0031] By setting up the ventilation pipe 10 with rotation and vertical displacement, it is possible to effectively mix the areas with higher temperature and lower temperature, avoid the phenomenon of accumulated temperature, reduce the risk of overheating, which helps to maintain the uniformity of the temperature inside the soil fertilizer, thereby reducing the impact of temperature fluctuations on the quality of the soil fertilizer; when the pipe rotates, it can enter the interior of the soil fertilizer and directly dissipate heat from the heat-accumulating area, ensuring that the heat is dissipated in time to prevent the soil fertilizer from spoiling or losing its nutritional value due to excessive temperature; through the rotating pipe, not only can ventilation be improved, but also the soil fertilizer can be turned over, promoting the air exchange inside and outside the soil fertilizer, accelerating the decomposition process of organic matter, and at the same time preventing uneven accumulation or long-term lack of air in some areas, avoiding problems such as piled-up spoilage.

[0032] Referring to Figure 5 , the ventilation pipe 10 includes an arc section 12 and a conical spiral section 13. The arc section 12 and the conical spiral section 13 are hollow and connected inside, and the connection between the arc section 12 and the conical spiral section 13 is sharp.

[0033] In this embodiment, the connection between the arc section 12 and the conical spiral section 13 is sharp in order to reduce the resistance of the ventilation pipe 10 when passing through the soil fertilizer layer during the reverse rotation and spiral ascent of the ventilation pipe 10. Both ends of the arc section 12 and the conical spiral section 13 that are not connected are fixed on the innermost sleeve 4 and are connected to the inner cavity of the sleeve 4.

[0034] By setting the ventilation pipe 10 as a conical spiral shape, the air flow path can be optimized, the air flow resistance can be reduced, and the ventilation effect can be enhanced; this helps to evenly distribute the air flow in the tank, avoid lack of ventilation or accumulation of moisture in local areas, thereby improving the air circulation efficiency of the storage environment; the conical design makes the air flow path more uniform in the diameter direction of the tank body 1, and at the same time, the conical spiral ventilation pipe 10 has less resistance when passing through the soil fertilizer during the rotation downward.

[0035] Referring to Figure 3 , the cross-section of the ventilation pipe 10 is fusiform.

[0036] In this embodiment, the fusiform cross-section has a streamlined shape, which can effectively reduce the contact area with the soil fertilizer and reduce the frictional resistance. This shape allows the object to cut through and pass through the soil fertilizer more smoothly, reducing energy loss. The two ends of the fusiform gradually narrow, and this shape can effectively divert the surrounding soil fertilizer, making the soil fertilizer flow more evenly in the front and rear parts of the object, and not forming a large area of resistance concentration. Compared with sharp or flat shapes, the fusiform object can reduce the "soil fertilizer accumulation" phenomenon, thereby reducing the difficulty of passing through.

[0037] In soil fertilizer, when an object passes through, it will generate shear force on the soil, resulting in soil damage and rearrangement. Spindle-shaped objects generate less intense shear force because their shape can distribute the force transmission more smoothly, unlike flat shapes that are prone to causing a large amount of soil accumulation and local pressure increase.

[0038] Furthermore, the conical slope of the conical spiral section 13 is 60°.

[0039] Refer to Figure 3 , by controlling the conical slope of the conical spiral section 13 to be 60°, the ventilation pipe 10 in the shape of a conical spiral has a smaller inclination angle and less resistance when rotating downward and penetrating into the soil fertilizer.

[0040] Refer to Figure 6 , an elastic pore membrane 14 is provided at the exhaust hole 11, and a slit 15 is opened on the elastic pore membrane 14.

[0041] In this embodiment, the slit 15 on the elastic pore membrane 14 is in a closed state when the exhaust hole 11 is not ventilated, which can prevent sand and soil from entering the ventilation pipe 10. When the exhaust hole 11 is ventilated, the slit 15 increases the airflow of the exhaust hole 11 and prevents sand and soil from flowing back into the ventilation pipe 10.

[0042] By providing the elastic pore membrane 14, dust is prevented from entering the exhaust hole 11.

[0043] Refer to Figure 1 , the driving assembly includes a driving motor 16 provided at the top of the tank body 1, a pulley one 17 provided on the main shaft of the driving motor 16, and a pulley two 18 sleeved on the top of the central rod 2 and connected to the first turntable 8. The pulley one 17 and the pulley two 18 are connected by a transmission belt 19.

[0044] In this embodiment, the driving motor 16 is fixed to the top of the tank body 1 through a bracket. The diameter of the pulley one 17 is smaller than that of the pulley two 18, which is used to increase the torque of the first turntable 8 and reduce the rotation speed, making it easier for the ventilation pipe 10 to penetrate into the soil fertilizer layer.

[0045] By providing the driving assembly, it is used to drive a pair of guide posts 7 to rotate, and further drive the ventilation pipe 10 to rotate downward.

[0046] Refer to Figure 3 , the air supply assembly includes an air supply cavity 20 provided at the upper end of the central rod 2, an air inlet hole 21 provided on the air supply cavity 20, the air inlet hole 21 communicating with the inner cavity of the sleeve 4, and an air inlet pipe 22 connected to the top of the central rod 2.

[0047] Through the air supply assembly, air enters the ventilation pipe 10 through the sleeve 4 to ventilate the center of the soil fertilizer.

[0048] Refer to Figure 1, a feed inlet 23 is provided at the top of the tank body 1, and a discharge outlet 24 is provided at the bottom of the tank body 1.

[0049] By providing the feed inlet 23 and the discharge outlet 24, it is used for feeding and discharging materials into the tank body 1.

[0050] The working principle of the present invention: During the use process, the soil fertilizer is put into the tank body 1 from the feed inlet 23. Connect the air inlet pipe 22 to the blower, and air enters the air supply cavity 20, the air inlet holes 21, the inner cavity of the sleeve 4, and the ventilation pipe 10 from the air inlet pipe 22, and finally is released into the tank body 1 through the exhaust holes 11. For the soil fertilizer piled up in the tank body 1, it is difficult for the bottom and the center to contact air, and the temperature rises. Regularly start the driving motor 16, and the driving motor 16 drives the belt pulley two 18 to rotate through the belt pulley one 17. The belt pulley two 18 drives the coaxial first turntable 8 to rotate. The first turntable 8 drives a pair of guide columns 7 to rotate. Since a pair of guide columns 7 are arranged between the rotating pipe 5 and the innermost sleeve 4, the rotating pipe 5 and the innermost sleeve 4 rotate along with a pair of guide columns 7. At the same time, the rotating pipe 5 and the innermost sleeve 4 rotate downward along the spiral groove 3, and the ventilation pipe 10 also rotates and moves downward synchronously. During this process, the ventilation pipe 10 evenly distributes the air flow in the tank, avoiding the lack of ventilation or the accumulation of moisture and local temperature accumulation in local areas, thereby improving the air circulation efficiency of the storage environment. At the same time, it can also play a role in turning the soil fertilizer, promoting the air exchange inside and outside the soil fertilizer, accelerating the decomposition process of organic matter, and at the same time preventing uneven accumulation or the lack of air in some areas for a long time, and avoiding problems such as piled-up corruption.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
