Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and more specifically, to an integrated water and fertilizer seedling raising device. Background Technology

[0002] Integrated water and fertilizer management refers to a new agricultural technology that combines irrigation and fertilization. It utilizes a pressure system (or natural topographical drop) to mix soluble solid or liquid fertilizers, formulated according to soil nutrient content and crop requirements, with irrigation water. This mixture is then supplied through a controlled pipeline system, allowing the water and fertilizer to blend. The resulting solution, delivered via drip irrigation or sprinkler irrigation, evenly, regularly, and quantitatively irrigates the root zone, maintaining loose and suitable moisture levels in the soil around the main root system. Integrated water and fertilizer management technology offers rapid fertilizer effectiveness and improved nutrient utilization. It avoids the volatilization losses and slow dissolution associated with applying fertilizer to dry topsoil, resulting in delayed fertilizer release. It particularly avoids the volatilization losses of ammonium and urea nitrogen fertilizers applied to the surface, thus saving nitrogen fertilizer and contributing to environmental protection.

[0003] In existing seedling cultivation processes, irrigation and fertilization are usually two separate operations. This not only increases labor intensity but also easily leads to uneven water and fertilizer supply, affecting the growth quality of crop seedlings. Therefore, developing a seedling cultivation device that integrates irrigation and fertilization to achieve precise and efficient water and fertilizer management has become a research hotspot in the current agricultural technology field. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an integrated water and fertilizer seedling raising device, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A water and fertilizer integrated seedling raising device includes a water and fertilizer mixing tank and a seedling bed. A fixed base is fixedly provided at the left end of the seedling bed, and a water and fertilizer mixing tank is provided on the fixed base. A stirring motor is installed at the front end of the water and fertilizer mixing tank. A stirring shaft is provided inside the water and fertilizer mixing tank, and the front end of the stirring shaft is fixedly connected to the output end of the stirring motor. Multiple sets of stirring blades are evenly installed on the stirring shaft. A first water pump is installed on the upper side of the water and fertilizer mixing tank. The output end of the first water pump is connected to the water and fertilizer mixing tank through a hose, and its input end is connected to an external water source through a hose. A fertilizer adding mechanism is provided on the rear side of the upper end face of the water and fertilizer mixing tank. A second water pump is installed on the fixed base on the right side of the water and fertilizer mixing tank. The input end of the second water pump is connected to the water and fertilizer mixing tank through a hose.

[0007] The seedling bed is supported by multiple sets of legs at the bottom. Multiple sets of partitions are spaced apart inside the seedling bed. The area between the partitions is filled with seedling substrate. A baffle is fixed at the left end of the seedling bed. A main pipe is installed on the baffle. The main pipe is connected to the output end of the second water pump through a hose. Two diversion pipes are symmetrically connected to the right side of the main pipe ring. The diversion pipes are fixed to the partition. Multiple sets of sprinkler pipes are evenly connected to the front and rear sides of the diversion pipe ring.

[0008] Furthermore, the fertilizer addition mechanism includes a cover plate, a storage cylinder, a crushing box, a connecting frame, a valve, and a feed pipe. The crushing box is located on the upper side of the water-fertilizer mixing box, and the crushing box is fixedly connected to the water-fertilizer mixing box through multiple sets of connecting frames. The bottom of the crushing box is connected to a feed pipe, and the lower end of the feed pipe is connected to the water-fertilizer mixing box. A valve is installed on the feed pipe. The upper side of the crushing box is connected to a storage cylinder, and the upper end of the storage cylinder is fitted with a cover plate by threads.

[0009] Furthermore, two sets of extrusion rollers are symmetrically arranged inside the crushing box. The right ends of the two sets of extrusion rollers are connected by a transmission gear, and a drive motor is installed on the left end of one set of extrusion rollers.

[0010] Furthermore, two sets of downward-sloping guide plates are symmetrically arranged on the front and rear sides inside the crushing box.

[0011] Furthermore, two sets of electric heating rods are provided on the left side inside the water-fertilizer mixing tank, and the positions of the electric heating rods are offset from the positions of the stirring blades.

[0012] Furthermore, the water-fertilizer mixing box has a transparent viewing window on its left end face.

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

[0014] 1. This utility model integrates irrigation and fertilization, enabling precise and efficient water and fertilizer management during seedling cultivation. It provides seedlings with uniform and sufficient water and nutrients, promotes healthy seedling growth, and improves seedling cultivation efficiency and seedling growth quality.

[0015] 2. This utility model features a fertilizer-adding mechanism that facilitates controlled fertilizer addition. It also includes a mechanism for compressing and pulverizing the fertilizer, breaking down fertilizer granules into powder for easier dissolution and faster mixing with water. When the drive motor starts, it rotates one set of compression rollers. Since the two sets of compression rollers are connected by a transmission gear, the other set also rotates synchronously. The two sets of rollers rotate in opposite directions, exerting pressure on the fertilizer and crushing it into fine particles. The pulverized fertilizer then enters the water-fertilizer mixing tank through the feed pipe, where it mixes thoroughly with water to form a water-fertilizer solution.

[0016] 3. In this utility model, two sets of downward-sloping guide plates are symmetrically arranged on the front and rear sides of the crushing box. The two sets of guide plates form a channel to guide the flow of fertilizer. When the fertilizer enters the crushing box, the guide plates will guide it to flow towards the extrusion roller, ensuring that the fertilizer can flow smoothly during the crushing process and be effectively crushed by the extrusion roller, while preventing the fertilizer from accumulating or blocking in a certain position inside the crushing box.

[0017] 4. This invention utilizes an electric heating rod to heat the water-fertilizer solution inside the mixing tank, thereby accelerating fertilizer dissolution and improving mixing efficiency. The heating rod raises the temperature of the water-fertilizer solution, accelerating fertilizer dissolution and improving the efficiency and quality of water-fertilizer mixing. Heating the solution makes the nutrients more active, facilitating crop absorption and utilization. Simultaneously, a suitable temperature promotes crop growth and development, thus improving seedling effectiveness. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] Example:

[0027] like Figures 1 to 6 As shown, an integrated water and fertilizer seedling raising device includes a water and fertilizer mixing tank 1 and a seedling bed 3. A fixed seat 4 is fixedly installed at the left end of the seedling bed 3. The water and fertilizer mixing tank 1 is installed on the fixed seat 4. A stirring motor 5 is installed at the front end of the water and fertilizer mixing tank 1. A stirring shaft 9 is installed inside the water and fertilizer mixing tank 1, and the front end of the stirring shaft 9 is fixedly connected to the output end of the stirring motor 5. Multiple sets of stirring blades 10 are evenly installed on the stirring shaft 9. A first water pump 6 is installed on the upper side of the water and fertilizer mixing tank 1. The output end of the first water pump 6 is connected to the water and fertilizer mixing tank 1 through a hose, and its input end is connected to an external water source through a hose. A fertilizer adding mechanism 2 is provided on the rear side of the upper end face of the water and fertilizer mixing tank 1. A second water pump 8 is installed on the fixed seat 4 on the right side of the water and fertilizer mixing tank 1. The input end of the second water pump 8 is connected to the water and fertilizer mixing tank 1 through a hose.

[0028] The bottom of the seedling bed 3 is supported by multiple sets of legs 33. The inside of the seedling bed 3 is equipped with multiple sets of partitions 35. The area between the partitions 35 is filled with seedling substrate 34. A baffle 32 is fixed at the left end of the seedling bed 3. A main pipe 31 is installed on the baffle 32. The main pipe 31 is connected to the output end of the second water pump 8 through a hose. Two branch pipes 36 are symmetrically connected to the right side of the main pipe 31. The branch pipes 36 are fixed to the partitions 35. Multiple sets of sprinkler pipes 37 are evenly connected to the front and rear sides of the branch pipes 36. This design solves the problem that irrigation and fertilization are usually two independent operations in the existing seedling process. This not only increases the labor intensity, but also easily leads to uneven water and fertilizer supply, which affects the growth quality of crop seedlings.

[0029] In this embodiment, the fertilizer adding mechanism 2 includes a cover plate 21, a storage cylinder 22, a crushing box 23, a connecting frame 25, a valve 26, and a feed pipe 27. The crushing box 23 is located on the upper side of the water-fertilizer mixing box 1, and the crushing box 23 is fixedly connected to the water-fertilizer mixing box 1 through multiple sets of connecting frames 25. The bottom of the crushing box 23 is connected to the feed pipe 27, and the lower end of the feed pipe 27 is connected to the water-fertilizer mixing box 1. The feed pipe 27 is equipped with a valve 26 for controlling the amount of fertilizer added. By opening or closing the valve 26, the time and amount of fertilizer added can be precisely controlled to ensure that the ratio and concentration of water-fertilizer mixing meet the actual needs. The upper side of the crushing box 23 is connected to the storage cylinder 22 for storing fertilizer. Its capacity can be adjusted according to actual needs. The upper end of the storage cylinder 22 is fitted with a cover plate 21 by threads. The cover plate 21 can ensure the sealing of the storage cylinder 22 to prevent the fertilizer from getting damp. At the same time, the cover plate 21 is also easy to open, making it convenient to add fertilizer to the storage cylinder 22. The design facilitates the control of fertilizer addition through the fertilizer addition mechanism 2.

[0030] In this embodiment, two sets of extrusion rollers 28 are symmetrically arranged inside the crushing chamber 23. The right ends of the two sets of extrusion rollers 28 are connected by a transmission gear 210, and a drive motor 24 is installed on the left end of one set of extrusion rollers 28. This design can crush fertilizer by extrusion, turning fertilizer particles into powder, which facilitates the subsequent dissolution of fertilizer and accelerates the mixing efficiency of fertilizer and water. When the drive motor 24 starts, it drives one set of extrusion rollers 28 to rotate. Since the two sets of extrusion rollers 28 are connected by the transmission gear 210, the other set of extrusion rollers 28 will also rotate synchronously. At this time, the two sets of extrusion rollers 28 will rotate in opposite directions and generate extrusion force on the fertilizer, crushing and pulverizing the fertilizer entering the crushing chamber 23 into fine particles. The crushed fertilizer will enter the water-fertilizer mixing chamber 1 through the feed pipe 27 and be fully mixed with water to form a water-fertilizer solution.

[0031] In this embodiment, two sets of downward-sloping guide plates 29 are symmetrically arranged on the front and rear sides inside the crushing box 23. The two sets of guide plates 29 form a channel to guide the flow of fertilizer. When fertilizer enters the crushing box 23, the guide plates 29 will guide it to flow towards the extrusion roller 28, ensuring that the fertilizer can flow smoothly during the crushing process and be effectively crushed by the extrusion roller 28, while preventing the fertilizer from accumulating or blocking at a certain position inside the crushing box 23.

[0032] In this embodiment, two sets of electric heating rods 11 are installed on the left side inside the water-fertilizer mixing tank 1, and the positions of the electric heating rods 11 are staggered from the positions of the stirring blades 10. The electric heating rods 11 heat the water-fertilizer solution inside the water-fertilizer mixing tank 1, thereby accelerating the dissolution rate of the fertilizer and improving the mixing efficiency. Heating the water-fertilizer solution increases the temperature of the solution, accelerating fertilizer dissolution and thus improving the efficiency and quality of water-fertilizer mixing. Heating the solution makes the nutrients in the solution more active, which is beneficial for crop absorption and utilization. At the same time, a suitable temperature can also promote crop growth and development, thereby improving seedling results.

[0033] In this embodiment, a transparent window 7 is provided on the left end face of the water-fertilizer mixing tank 1. The transparent window 7 allows the operator to directly observe the mixing situation inside the water-fertilizer mixing tank 1. The degree of mixing of water and fertilizer can be clearly seen through the transparent window 7. At the same time, the operator can also conveniently monitor the water level changes in the water-fertilizer mixing tank 1 and conveniently replenish water in a timely manner.

[0034] The working principle of this integrated water and fertilizer seedling raising device is as follows: First, the operator injects an appropriate amount of water into the water and fertilizer mixing tank 1 through an external water source and the first water pump 6. Simultaneously, according to the actual needs of seedling raising, an appropriate amount of fertilizer is added to the storage cylinder 22, and the cover plate 21 ensures the sealing of the storage cylinder 22 to prevent the fertilizer from getting damp. Next, the valve 26 is opened and the drive motor 24 is started, driving a set of extrusion rollers 28 inside the crushing box 23 to rotate. Since the two sets of extrusion rollers 28 are connected by a transmission gear 210, the other set of extrusion rollers 28 will also rotate synchronously. In this way, the two sets of extrusion rollers 28 will rotate in opposite directions, extruding and crushing the fertilizer entering the crushing box 23 into fine particles. The crushed fertilizer enters the water and fertilizer mixing tank 1 through the feed pipe 27. Inside the water and fertilizer mixing tank 1, the stirring motor 5 is started, driving the stirring shaft 9 and stirring blades 10 to rotate, thoroughly mixing the water and fertilizer. Simultaneously, the electric heating rod 11 starts working, heating the water-fertilizer solution inside the water-fertilizer mixing tank 1 to accelerate the dissolution rate of the fertilizer and improve mixing efficiency. Heating raises the temperature of the water-fertilizer solution, making the fertilizer easier to dissolve, thus improving the quality of water-fertilizer mixing. Operators can directly observe the internal mixing process through the transparent viewing window 7 on the left side of the water-fertilizer mixing tank 1 to ensure that the water and fertilizer are mixed evenly. Water level changes can also be monitored to replenish water promptly. Once the water-fertilizer solution is evenly mixed and reaches a suitable temperature, the second water pump 8 is activated, delivering the water-fertilizer solution through a hose to the main pipe 31 of the seedling bed 3. Two symmetrically connected branch pipes 36 on the right side of the main pipe 31 distribute the water-fertilizer solution to the area between the partitions 35. Then, through multiple sets of sprinkler pipes 37 evenly connected on both sides of the branch pipes 36, the water-fertilizer solution is evenly sprayed into the seedling substrate 34, providing sufficient and uniform water and nutrients for the crop seedlings.

[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
