Description

Technical Field

[0001] The invention relates to the technical field of water-fertilizer integrated irrigation, in particular to water-fertilizer integrated irrigation equipment for forestry seedlings. Background Art

[0002] Integrated fertigation is a modern agricultural technology that combines irrigation and fertilization. Using an intelligent system, water and soluble fertilizer are mixed in a scientifically formulated ratio and delivered directly to the plant's root zone (e.g., drip irrigation or sprinkler irrigation). This technology aims to improve seedling growth efficiency, conserve water resources, and reduce fertilizer use by precisely controlling the supply of water and nutrients. Precisely controlling the supply of water and nutrients significantly improves water and fertilizer efficiency, promoting healthy seedling growth and serving as a key strategy for sustainable forestry development.

[0003] However, the existing forestry seedling water and fertilizer integrated irrigation equipment still has the following problems: 1. In some cases, solid or powdered fertilizers must first be mixed with water to form a water-fertilizer mixture before being connected to the irrigation system. However, solid or powdered fertilizers are hydrophobic and difficult to disperse in water. They easily form lumps or agglomerates and have poor fluidity, which results in some nutrients not being able to dissolve in a timely and sufficient manner. This leads to uneven nutrient distribution, uneven crop absorption, and decreased fertilizer utilization. At the same time, undissolved fertilizers may form high salt concentrations in local areas, causing plant root burns or inhibiting water absorption. They may also cause sedimentation and block the irrigation system, thereby affecting overall operation efficiency.

[0004] 2. In addition, if a single-point feeding method is adopted, fertilizer tends to accumulate near the feeding port, and the amount of fertilizer added is difficult to control, forming a local high-density area, further exacerbating the risk of insufficient dissolution; at the same time, incompletely dispersed granular or powdered fertilizer may be deposited at the bottom of the tank or the inner wall of the pipe, which may easily cause equipment wear or blockage under long-term operation, affecting the stability of the irrigation system and fertilizer utilization rate. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a forestry seedling water and fertilizer integrated irrigation device, which solves the problems raised in the background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a forestry seedling water and fertilizer integrated irrigation equipment, including: a fertilizer tank body; a feed pipe, the feed pipe is located on the side of the fertilizer tank body, used for fertilizer to enter the fertilizer tank body; a sliding sleeve, the sliding sleeve is arranged in the feed pipe and can slide along the axial direction of the feed pipe, and the sliding sleeve is provided with a stirring blade assembly; a central shaft, the central shaft is located at the axial center position of the fertilizer tank body, and the central shaft can rotate actively; a linkage assembly, the linkage assembly is used to connect the sliding sleeve and the central shaft, so that the central shaft drives the sliding sleeve to reciprocate radially along the fertilizer tank body; an irrigation head, the irrigation head is connected to the fertilizer tank body discharge valve through an irrigation pipe.

[0011] Furthermore, a material holding pipe is provided, which is slidably matched with the feed pipe and is used to hold fertilizer. A limit plate is provided in the material holding pipe, and a threaded rod which is threadedly connected to the material holding pipe is rotatably installed on the limit plate.

[0012] Furthermore, a vertical rod is installed on the upper end of the convex frame, and a multi-rod stirring frame is rotatably installed on the outer side of the vertical rod.

[0013] Furthermore, a filter screen located on the inner wall of the tank top is sleeved on the outer side of the central shaft, and friction rods are arranged below the filter screen and are evenly installed on the outer side of the central shaft in a circumferential direction.

[0014] Furthermore, the filter is rotatably connected to the central shaft and the fertilizer tank body through a rotating sleeve. A bevel gear 1 is mounted on the upper end of the rotating sleeve. A bevel gear 2 fixedly mounted on the central shaft is provided above the bevel gear 1. A bevel gear 3 is meshed between the bevel gear 1 and the bevel gear 2. The upper end of the central shaft is connected to the output end of the drive motor.

[0015] Furthermore, scrapers located on the bottom wall of the fertilizer tank are evenly installed on the outer circumference of the central axis.

[0016] The present invention has the following beneficial effects: (1) The forestry seedling water and fertilizer integrated irrigation equipment, the stirring blade realizes multi-dimensional stirring of the fertilizer at the outlet of the feed pipe through the coordinated action of axial reciprocating movement, rotational movement and opening and closing action. This stirring method is not limited by the wall of the fertilizer tank and effectively expands the stirring range. The stirring blade breaks the fertilizer accumulation through axial movement, provides shear force to accelerate diffusion through rotational movement, and adjusts the stirring intensity through opening and closing action, which significantly improves the mixing uniformity of the water-fertilizer mixture, avoids abnormal crop growth caused by local excessive concentration, promotes full contact between fertilizer and water flow, effectively prevents the blockage of the delivery pipeline or fertilizer agglomeration, and adapts to complex fertilizer working conditions such as high viscosity and easy agglomeration, thereby reducing the risk of irrigation blockage and improving water and fertilizer utilization and crop absorption efficiency.

At the same time, different filling pipes for holding fertilizers can be inserted into different feeding pipes, and fertilizers can be evenly put into the fertilizer tank at multiple points, which can avoid the fertilizer from being concentrated in a certain area, thereby reducing local accumulation or agglomeration of powdered materials, helping to shorten the operation time and improve the overall efficiency.

[0018] (3) The forestry seedling water and fertilizer integrated irrigation equipment intercepts the floating granular or powdered fertilizer through a filter screen, and the friction rod rotating in the opposite direction can generate a certain shear force and friction through mechanical movement, breaking the larger particles or agglomerated powder into smaller particles, significantly reducing their particle size, thereby increasing the dissolution contact area per unit volume and accelerating the dissolution rate. At the same time, the structure of the particle surface can be destroyed or become looser, which helps water to penetrate more easily into the particles or powder, promotes the dissolution process, and is also conducive to releasing more active nutrients, further improving the dissolution efficiency and mixing uniformity of the fertilizer, helping to ensure the quality of the water-fertilizer mixture, and providing a high-quality foundation for subsequent water-fertilizer integrated applications.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0024] The following is based on Figures 1-11 The present invention provides a water-fertilizer integrated irrigation device for forestry seedlings.

[0025] See also Figure 1 、 Figure 2 、 Figure 7 and Figure 8 The forestry seedling water and fertilizer integrated irrigation equipment includes a fertilizer tank body 1, a feed pipe 11 and a filling pipe 12. The fertilizer tank body 1 is used to store a water-fertilizer mixture. The feed pipe 11 is located on the side of the fertilizer tank body 1 and is provided with one or more. In this embodiment, three feed pipes 11 are provided on the four sides of the fertilizer tank body 1. The feed pipe 11 is used for fertilizer to enter the fertilizer tank body 1. The filling pipe 1 is sleeved in the feed pipe 11 and slidably cooperates with the feed pipe 11 to hold fertilizer. A limiting plate 121 is provided in the filling pipe 12, and a threaded rod 122 threadedly connected to the filling pipe 12 is rotatably installed on the limiting plate 121. The filling pipe 12 is made of transparent material and a scale mark is provided on its outer side.

[0026] During use (working), different types of fertilizers or fertilizers of the same type can be evenly put into different feeding pipes 12 according to needs. The fertilizers can be granular, powdered or liquid fertilizers. Before that, the threaded rod 122 can be rotated and the limit plate 121 can be moved to a suitable position along the feeding pipe 12 with reference to the scale mark to change the holding capacity of the feeding pipe 12. Then, the fertilizer is put into the feeding pipe 12 according to the amount to achieve a precise ratio of the water-fertilizer mixture. Since multiple feeding pipes 11 are provided on the outside of the fertilizer tank body 1, the feeding pipes 12 for different fertilizers can be inserted into different feeding pipes 11, and the feeding pipes 12 can feed the fertilizer into the fertilizer tank body 1 through the feeding pipes 11. The fertilizer is evenly put into the fertilizer tank body 1 at multiple points, which can avoid the fertilizer from being concentrated in a certain area, thereby reducing local accumulation or agglomeration of powdered materials, helping to shorten the operation time and improve overall efficiency. Then, the existing water pump can inject water from the upper end of the fertilizer tank body 1 into the fertilizer tank body 1 through the water pipe.

[0027] See also Figure 2 、 Figure 3 、 Figure 7 and Figures 9-11The feed pipe 11 is provided with a sleeve 111, which is movably matched with the feed pipe 11 and can slide axially and rotate circumferentially along the feed pipe 11. A spiral blade 112 is installed on the inside of the sleeve 111 to accelerate the discharge of fertilizer from the feed pipe 11. A return spring 113 is provided in the feed pipe 11 between the fertilizer tank body 1 and the sleeve 111. A spiral groove 114 is provided in the feed pipe 11, and a protrusion 115 that cooperates with the spiral groove 114 is installed on the outside of the sleeve 111. When the sleeve 111 slides left and right, the spiral groove 114 and the protrusion 115 can realize the rotation state of the sleeve 111. When the sleeve 111 rotates, it can drive the spiral blade 112 to rotate, so that the spiral blade can promote the movement of the fertilizer, thereby sending the fertilizer into the fertilizer tank body 1.

[0028] In order to further stir the fertilizer, a stirring blade assembly is provided on the sliding sleeve 111. When the sliding sleeve 111 rotates, the stirring blade assembly also rotates, thereby stirring the fertilizer. Specifically, the stirring blade assembly here includes a fixed ring 116 fixedly installed on the outside of the sliding sleeve 111, and a stirring blade 117 is provided on the outside of the fixing ring 116. The stirring blade 117 is hinged to the fixing ring 116 through a folding rod 118. A rotating ring 119 is rotatably installed on the outside of the feeding pipe 11, and a connecting rod 110 is hinged between the folding rod 118 and the rotating ring 119. A telescopic column 120 is connected between the rotating ring 119 and the fixing ring 116.

[0029] In this embodiment, when the sleeve 111 moves left and right and rotates, the fixed ring 116 can drive the stirring blade 117 to move left and right and rotate. Its left and right movement can expand the stirring area and improve the uniformity of the mixture. The reason for providing the folding rod 118 and the connecting rod 110 is to adjust the opening angle of the stirring blade 117 to achieve multi-dimensional stirring of the fertilizer at the outlet of the feed pipe 11. The folding rod 118 and the connecting rod 110 can synchronously assist the stirring blade 117 to enhance the stirring intensity. This stirring method is not restricted by the wall of the fertilizer tank 1 and effectively expands the stirring range. The stirring blade 117 breaks up the fertilizer accumulation through axial movement, provides shear force to accelerate diffusion through rotational movement, and adjusts the stirring intensity through opening and closing action, which significantly improves the activity and mixing uniformity of the water-fertilizer mixture, avoids abnormal crop growth caused by excessive local concentration, promotes full contact between fertilizer and water flow, effectively prevents blockage of the delivery pipeline or fertilizer agglomeration, and adapts to complex fertilizer working conditions such as high viscosity and easy agglomeration, thereby reducing the risk of irrigation blockage and improving water and fertilizer utilization rate and crop absorption efficiency.

[0030] See also Figure 2 、 Figure 3 and Figure 5-Figure 7In order to realize the left and right movement of the sliding sleeve 111, a central shaft 13 is rotatably installed at the axial position of the fertilizer tank body 1. The central shaft 13 can rotate actively. A linkage component is connected between the sliding sleeve 111 and the central shaft 13, so that the central shaft 13 drives the sliding sleeve 111 to reciprocate along the radial direction of the fertilizer tank body 1.

[0031] Specifically, the above-mentioned linkage assembly includes a convex frame 131 sleeved on the central shaft 13, and a connecting frame 132 that slides with the convex frame 131 is provided below the sliding sleeve 111. The connecting frame 132 is installed at the lower end of the fixing ring 116, and a vertical rod 133 is installed at the upper end of the convex frame 131. A multi-rod stirring frame 134 is rotatably installed on the outer side of the vertical rod 133. When the convex frame 131 rotates with the central shaft 13, the vertical rod 133 drives the multi-rod stirring frame 134 to rotate synchronously, and the multi-rod stirring frame 134 can rotate around the vertical rod 133 under the impact force of the water flow, thereby realizing auxiliary stirring of the water-fertilizer mixture. Combining the principles of rotation and revolution stirring is conducive to improving the mixing uniformity and improving the water-fertilizer mixing efficiency.

[0032] In this embodiment, after a certain amount of water is injected into the fertilizer tank body 1, the central shaft 13 can drive the convex frame 131 to rotate. When the convex frame 131 rotates, it cooperates with the connecting frame 132 and pushes the connecting frame 132, the fixing ring 116 and the sliding sleeve 111 to move radially along the fertilizer tank body 1. When the sliding sleeve 111 is subjected to the force of the convex part of the convex frame 131, it can move along the feeding pipe 11 toward the inner wall of the fertilizer tank body 1 by compressing the reset spring 113. After the convex part of the convex frame 131 moves away from the connecting frame 132, the sliding sleeve 111 can be reset under the rebound force of the reset spring 113, thereby causing the sliding sleeve 111 to move back and forth axially along the feeding pipe 11.

[0033] While the sleeve 111 moves axially along the feed pipe 11, the protrusion 115 on the outside of the sleeve 111 can slide and cooperate with the spiral groove 114 in the feed pipe 11 to make the sleeve 111 rotate circumferentially along the feed pipe 11. In addition, the fixed ring 116 can move synchronously with the sleeve 111, and the fixed ring 116 drives the rotating ring 119 to rotate synchronously around the feed pipe 11 through the synchronously telescopic column 120. The connecting rod 110, the folding rod 118 and the stirring blade 117 rotate synchronously with the fixed ring 116 and the rotating ring 119. At the same time, as the sleeve 111 and the fixed ring 116 move, the angle between the connecting rod 110 and the folding rod 118 changes synchronously. Under the cooperation of the folding rod 118 and the connecting rod 110, the stirring blade 117 can gradually rotate outward around the hinge point between the folding rod 118 and the fixed ring 116, thereby realizing the change of the angle of the stirring blade 117.

[0034] In addition, since the feeding pipe 12 for holding fertilizer is inserted into the feeding pipe 11, the spiral blade 112 that moves and rotates synchronously with the sliding sleeve 111 can spirally transport the fertilizer in the feeding pipe 12 and the feeding pipe 11 to the fertilizer tank 1 through the water flow, and can pre-uniformly disperse and fully mix the fertilizer while ensuring that the fertilizer can be effectively and fully injected into the fertilizer tank 1, avoiding the presence of residual fertilizer in the feeding pipe 12 or the feeding pipe 11, thereby improving the utilization rate of fertilizer. In addition, the stirring blade 117 realizes multi-dimensional stirring of the fertilizer at the outlet of the feeding pipe 11 through the synergistic effect of axial reciprocating movement, rotational movement and opening and closing action, and the folding rod 118 and the connecting rod 110 can synchronously assist the stirring blade 117 to enhance the stirring intensity. This stirring method is not limited by the wall of the fertilizer tank 1 and effectively expands the stirring range. The stirring blade 117 breaks up the fertilizer accumulation through axial movement, provides shear force to accelerate diffusion through rotational movement, and adjusts the stirring intensity through opening and closing action, which significantly improves the activity and mixing uniformity of the water-fertilizer mixture, avoids abnormal crop growth caused by excessive local concentration, promotes full contact between fertilizer and water flow, effectively prevents blockage of the delivery pipeline or fertilizer agglomeration, and adapts to complex fertilizer working conditions such as high viscosity and easy agglomeration, thereby reducing the risk of irrigation blockage and improving water and fertilizer utilization and crop absorption efficiency.

[0035] See also Figure 1-Figure 5 The outer side of the central shaft 13 is provided with a filter screen 14 located on the inner wall of the tank top, and a friction rod 15 is provided below the filter screen 14 and is evenly installed on the outer side of the central shaft 13 in the circumferential direction. The filter screen 14 is rotatably connected to the central shaft 13 and the fertilizer tank body 1 through a rotating sleeve 141. A support frame is installed on the upper end of the fertilizer tank body 1. A bevel gear 1 142 is rotatably connected to the support frame on the upper end of the rotating sleeve 141. A bevel gear 2 143 fixedly mounted on the central shaft 13 is provided above the bevel gear 1 142. The bevel gear 1 142 and the bevel gear 2 are rotatably connected. 143 is meshed with a bevel gear three 144, and the bevel gear three 144 is rotatably mounted on the support frame. The upper end of the central shaft 13 is connected to the output end of the drive motor 16, and the drive motor 16 is mounted on the support frame. In addition, scrapers 17 located on the bottom wall of the fertilizer tank body 1 are evenly installed on the outer circumference of the central shaft 13. The scraper 17 can rotate synchronously with the central shaft 13 to dynamically scrape the bottom wall of the fertilizer tank body 1 and disturb the material, break the sedimentation layer, prevent the local concentration from being too high due to material accumulation, and further improve the water-fertilizer mixing efficiency.

[0036] In this embodiment, the central shaft 13 in the above working process can be driven to rotate by the driving motor 16. In addition, since the fertilizer may be in granular or powdery form and has a certain hydrophobicity, part of the fertilizer may float on the top wall of the fertilizer tank 1 due to buoyancy. In order to better mix this part of the fertilizer with water, the filter 14 is used to filter and intercept the floating granular or powdery fertilizer. During this process, the central shaft 13 can drive the bevel gear 2 143 to rotate synchronously with the friction rod 15. Under the action of the bevel gear 3 144 meshing with the bevel gear 2 143, the bevel gear 1 142 meshing with the bevel gear 3 144 can drive the filter 14 to rotate synchronously with the friction rod 15 through the rotating sleeve 141. Under the interaction between the filter screen 14 and the friction rod 15, the friction rod 15 can refine the particle size and activate the surface of the fertilizer intercepted by the filter screen 14 through shear force grinding, breaking larger particles or agglomerated powder into finer particles, significantly reducing their particle size, thereby increasing the dissolution contact area per unit volume and accelerating the dissolution rate. At the same time, the structure of the particle surface can be destroyed or become looser, which helps water to penetrate more easily into the particles or powder, promotes the dissolution process, and is also conducive to releasing more active nutrients, prompting the fertilizer to be better and faster dispersed and dissolved in water, further improving the dissolution efficiency and mixing uniformity of the fertilizer, and helping to ensure the quality of the water-fertilizer mixture, and thus ensure the subsequent irrigation quality.

[0037] See also Figure 1 The lower end of the fertilizer tank 1 is provided with a discharge port, and the lower end of the discharge port is provided with a discharge valve. The irrigation head 18 is connected to the discharge valve through an irrigation pipe 19. The irrigation head 18 and the irrigation pipe 19 are both connected to the existing irrigation system. The specific irrigation system is not shown in the figure.

[0038] Specifically, after the water-fertilizer mixture in the fertilizer tank 1 is evenly stirred, the discharge valve can be opened for direct use. The existing irrigation system can use a fertilizer injection pump to transport the water-fertilizer mixture to the irrigation pipe 19 as needed, and directly irrigate the corresponding forestry seedlings through the irrigation head 18. This method can not only reduce the time spent on mixing water and fertilizer separately, improve overall operating efficiency, but also solve the problem of uneven fertilization or blockage of the irrigation system.
