Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water and fertilizer integrated irrigation, specifically to a forestry seedling water and fertilizer integrated irrigation equipment. BACKGROUND

[0002] Water and fertilizer integrated irrigation is a modern agricultural technology that combines irrigation and fertilization. Through an intelligent system, water and soluble fertilizers are mixed in a scientific ratio and then directly delivered to the plant root zone (such as drip irrigation, sprinkler irrigation, etc.). The purpose is to improve seedling growth efficiency, save water resources, and reduce the use of chemical fertilizers by precisely controlling water and nutrient supply. By precisely controlling water and nutrient supply, the use efficiency of water and fertilizer can be greatly improved, which helps to promote the healthy growth of seedlings and is a key strategy for sustainable development of forestry.

[0003] However, the existing forestry seedling water and fertilizer integrated irrigation equipment still has the following problems:

[0004] 1. In some cases, solid or powdered fertilizer needs to be mixed with water to form a water and fertilizer mixture before being introduced into the irrigation system. However, solid or powdered fertilizer has a certain hydrophobicity and is difficult to disperse in water, easily forming hard clumps or aggregates with poor flowability. This results in incomplete dissolution of some nutrients, uneven nutrient distribution, and unbalanced nutrient absorption by crops, leading to decreased fertilizer utilization efficiency. Additionally, undissolved fertilizer may form high-concentration salt in local areas, causing root burn or water absorption inhibition in plants, and may also cause sedimentation and blockage of the irrigation system, further affecting overall operational efficiency.

[0005] 2. Furthermore, if a single point feeding method is used, fertilizer is prone to accumulate near the feeding port, and the amount of fertilizer fed is difficult to control, forming a local high-density area that further exacerbates the risk of incomplete dissolution. At the same time, undispersed granular or powdered fertilizer may deposit at the bottom of the tank or on the inner wall of the pipeline, causing equipment wear or blockage over long-term operation, affecting the stability of the irrigation system and fertilizer utilization efficiency.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0035] In the description of the present application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery" and the like indicate the orientation or positional relationship, only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0036] In the following Figures 1-11 An embodiment of the present application provides a forestry nursery water and fertilizer integrated irrigation equipment.

[0037] Please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 , the forestry nursery water and fertilizer integrated irrigation equipment includes a fertilizer tank body 1, a feeding pipe 11 and a material containing pipe 12, the fertilizer tank body 1 is used for storing water and fertilizer mixture, the feeding pipe 11 is located on the side of the fertilizer tank body 1, and is provided with one or more, in the embodiment, three feeding pipes 11 are arranged on the four sides of the fertilizer tank body 1, the feeding pipe 11 is used for the fertilizer to enter the fertilizer tank body 1, the material containing pipe 1 is sleeved in the feeding pipe 11 and is in sliding fit with the feeding pipe 11, and is used for containing the fertilizer, the material containing pipe 12 is provided with a limiting plate 121, the limiting plate 121 is rotatably installed with a threaded rod 122 which is in threaded connection with the material containing pipe 12, the material containing pipe 12 is of transparent material and is provided with a scale mark on the outside.

[0038] In use (when working), different types of fertilizers or the same type of fertilizer can be uniformly put into different material containing pipes 12 according to the needs, the fertilizer can be granular, powdery or liquid fertilizer, and before that, the threaded rod 122 can be rotated and the limiting plate 121 can be moved to the appropriate position along the material containing pipe 12 by referring to the scale mark, so as to change the containing capacity of the material containing pipe 12, then the fertilizer is put into the material containing pipe 12 according to the amount, so as to realize the accurate proportioning of the water and fertilizer mixture, since the fertilizer tank body 1 is provided with a plurality of feeding pipes 11, the material containing pipes 12 containing different fertilizers can be inserted into different feeding pipes 11, and the material containing pipe 12 can send the fertilizer into the fertilizer tank body 1 through the feeding pipe 11, so that the fertilizer can be uniformly put into the fertilizer tank body 1 from multiple points, thereby avoiding the concentration of the fertilizer in a certain area, reducing the local accumulation or caking of powdery materials, helping to shorten the operation time, and being higher in overall efficiency, then the existing water pump can inject water into the fertilizer tank body 1 through the water pipe from the upper end of the fertilizer tank body 1.

[0039] Please refer to Figure 2 , Figure 3 , Figure 7 and Figures 9-11The feeding pipe 11 is sleeved with a sliding sleeve 111, which is movably connected with the feeding pipe 11 and can axially slide and circumferentially rotate along the feeding pipe 11. The sliding sleeve 111 is internally provided with a helical blade 112 for accelerating the discharge of the fertilizer from the feeding pipe 11. The feeding pipe 11 is internally provided with a reset spring 113 between the fertilizer tank body 1 and the sliding sleeve 111. The feeding pipe 11 is internally provided with a helical groove 114, and the sliding sleeve 111 is externally provided with a protrusion 115 matched with the helical groove 114. Therefore, when the sliding sleeve 111 slides left and right, the sliding sleeve 111 can rotate due to the matching of the helical groove 114 and the protrusion 115. When the sliding sleeve 111 rotates, the helical blade 112 can rotate, so that the helical blade can push the fertilizer to move and send the fertilizer into the fertilizer tank body 1.

[0040] In order to further stir the fertilizer, the sliding sleeve 111 is provided with a stirring blade assembly. When the sliding sleeve 111 rotates, the stirring blade assembly also rotates, so as to stir the fertilizer. Specifically, the stirring blade assembly includes a fixed ring 116 fixedly installed on the outside of the sliding sleeve 111. The fixed ring 116 is externally provided with a stirring blade 117, which is hingedly connected with the fixed ring 116 through a foldable rod 118. A rotating ring 119 is rotatably installed on the outside of the feeding pipe 11. A connecting rod 110 is hingedly connected between the foldable rod 118 and the rotating ring 119. An extension column 120 is connected between the rotating ring 119 and the fixed ring 116.

[0041] In the embodiment, when the sliding 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. The left and right movement of the stirring blade 117 can expand the stirring area and improve the uniformity of the mixture. The foldable rod 118 and the connecting rod 110 are arranged to adjust the opening angle of the stirring blade 117, so as to realize multi-dimensional stirring of the fertilizer at the outlet of the feeding pipe 11. The foldable rod 118 and the connecting rod 110 can synchronously assist the stirring blade 117 to enhance the stirring strength. The stirring mode is not limited by the wall of the fertilizer tank body 1 and effectively expands the stirring range. The stirring blade 117 breaks the fertilizer accumulation through axial movement, provides shear force through rotational movement to accelerate diffusion, and adjusts the stirring strength through opening and closing actions. The activity and mixing uniformity of the water-fertilizer mixture are significantly improved. The local concentration is prevented from being too high to cause abnormal growth of crops. The full contact between the fertilizer and the water flow is promoted. The blockage of the conveying pipe or the caking of the fertilizer is effectively prevented. The complex fertilizer working conditions such as high viscosity and easy caking are adapted. Therefore, the irrigation blockage risk is reduced, and the water-fertilizer utilization rate and the crop absorption efficiency are improved.

[0042] Please refer to Figure 2 , Figure 3 and Figures 5-7In 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 be driven to rotate, and a linkage assembly is connected between the central shaft 13 and the sliding sleeve 111, so that the central shaft 13 drives the sliding sleeve 111 to move reciprocatingly along the radial direction of the fertilizer tank body 1.

[0043] Specifically, the linkage assembly includes a convex frame 131 sleeved on the central shaft 13, a connecting frame 132 is arranged below the sliding sleeve 111 and is in sliding cooperation with the convex frame 131, the connecting frame 132 is installed at the lower end of the fixed ring 116, a vertical rod 133 is installed at the upper end of the convex frame 131, a multi-rod stirring frame 134 is rotatably installed at 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 influence of the water flow impact force, so as to realize the auxiliary stirring of the water-fertilizer mixture. Combined with the principle of revolution and rotation stirring, it is beneficial to improve the mixing uniformity and improve the water-fertilizer mixing efficiency.

[0044] 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, the convex frame 131 cooperates with the connecting frame 132 when rotating and pushes the connecting frame 132, the fixed ring 116 and the sliding sleeve 111 to move along the radial direction of 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 direction of the inner wall of the fertilizer tank body 1 through the compression of 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, so that the sliding sleeve 111 moves reciprocatingly along the axial direction of the feeding pipe 11.

[0045] When the sliding sleeve 111 moves along the axial direction of the feeding pipe 11, the protrusion 115 at the outer side of the sliding sleeve 111 can slide with the spiral groove 114 in the feeding pipe 11, so that the sliding sleeve 111 rotates along the circumferential direction of the feeding pipe 11, in addition, the fixed ring 116 can move synchronously with the sliding sleeve 111, the fixed ring 116 drives the rotating ring 119 to rotate synchronously around the feeding pipe 11 through the synchronous extension and contraction of the telescopic column 120, the connecting rod 110, the folded rod 118 and the stirring blade 117 rotate synchronously with the fixed ring 116 and the rotating ring 119, at the same time, with the movement of the sliding sleeve 111 and the fixed ring 116, the angle between the connecting rod 110 and the folded rod 118 changes synchronously, and the stirring blade 117 can gradually rotate outward around the hinge point between the folded rod 118 and the fixed ring 116 under the cooperation of the folded rod 118 and the connecting rod 110, so as to realize the change of the opening angle of the stirring blade 117.

[0046] In addition, since the fertilizer containing pipe 12 is inserted into the feeding pipe 11, the spiral blade 112 which moves and rotates synchronously with the sliding sleeve 111 can screw the fertilizer in the fertilizer containing pipe 12 and the feeding pipe 11 to the fertilizer tank 1 through the water flow, uniformly disperses and fully mixes the fertilizer in advance, ensures that the fertilizer can be effectively and fully injected into the fertilizer tank 1, avoids the existence of residual fertilizer in the fertilizer containing pipe 12 or the feeding pipe 11, and further improves the fertilizer utilization rate. 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, rotary motion and opening and closing action. The foldable 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 the fertilizer accumulation through axial movement, provides shear force through rotary motion to accelerate diffusion, and adjusts the stirring intensity through opening and closing action, significantly improves the activity and mixing uniformity of the water-fertilizer mixture, avoids local high concentration which leads to abnormal growth of crops, promotes full contact between the fertilizer and the water flow, effectively prevents blockage of the conveying pipeline or caking of the fertilizer, adapts to complex fertilizer working conditions such as high viscosity and easy caking, thereby reducing the risk of irrigation blockage, improving water and fertilizer utilization rate and crop absorption efficiency.

[0047] Please refer to Figures 1-5 , the outer side of the central shaft 13 is sleeved with a filter screen 14 located on the inner wall of the tank top. A friction rod 15 is circumferentially and uniformly installed on the outer side of the central shaft 13 below the filter screen 14. The filter screen 14 is rotationally connected with the central shaft 13 and the fertilizer tank 1 through a rotating sleeve 141. A support frame is installed on the upper end of the fertilizer tank 1. A bevel gear one 142 rotationally connected with the support frame is sleeved on the upper end of the rotating sleeve 141. A bevel gear two 143 is fixedly sleeved on the central shaft 13 above the bevel gear one 142. A bevel gear three 144 is engaged between the bevel gear one 142 and the bevel gear two 143 and is rotationally installed on the support frame. The upper end of the central shaft 13 is connected with the output end of a driving motor 16. The driving motor 16 is installed on the support frame. In addition, a scraper 17 is circumferentially and uniformly installed on the bottom wall of the fertilizer tank 1 on the outer side of the central shaft 13. The scraper 17 can rotate synchronously with the central shaft 13 to dynamically scrape and disturb the material on the bottom wall of the fertilizer tank 1, break the sedimentation layer, prevent local high concentration caused by material accumulation, and further improve the water-fertilizer mixing efficiency.

[0048] In the embodiment, the central shaft 13 in the working process can be driven to rotate by the driving motor 16. In addition, since the fertilizer can be in the form of particles or powder and has a certain hydrophobicity, part of the fertilizer can float on the top wall of the fertilizer tank 1 due to the buoyancy. In order to better mix the part of the fertilizer with water, the filter screen 14 is used to filter and intercept the floating particle or powder fertilizer. In this process, the central shaft 13 can drive the bevel gear two 143 to rotate synchronously with the friction rod 15. Under the action of the bevel gear three 144 engaged with the bevel gear two 143, the bevel gear one 142 engaged with the bevel gear three 144 can drive the filter screen 14 to rotate reversely synchronously with the friction rod 15 through the rotating sleeve 141. Under the interaction of the filter screen 14 and the friction rod 15, the friction rod 15 can grind the fertilizer intercepted by the filter screen 14 through the shearing force to refine the particle size and activate the surface of the fertilizer, so that the larger particles or agglomerated powder are broken into smaller particles, the particle size is significantly reduced, the dissolution contact area in unit volume is increased, the dissolution rate is accelerated, the structure of the particle surface is damaged or becomes looser, water can penetrate into the interior of the particle or powder more easily, the dissolution process is promoted, more active nutrient components are released, the fertilizer is better and faster dispersed and dissolved in water, the dissolution efficiency and mixing uniformity of the fertilizer are further improved, the quality of the water-fertilizer mixture is ensured, and then the subsequent irrigation quality is ensured.

[0049] Please refer to 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 with the discharge valve through the irrigation pipe 19. The irrigation head 18 and the irrigation pipe 19 are connected with the existing irrigation system, and the specific irrigation system is not shown in the figure.

[0050] Specifically, after the water-fertilizer mixture in the fertilizer tank 1 is uniformly stirred, the discharge valve can be opened for direct use. The existing irrigation system can use a fertilizer injection pump to deliver the water-fertilizer mixture to the irrigation pipe 19 as needed, and then directly irrigate the corresponding forestry seedlings through the irrigation head 18. This mode can not only reduce the time consumed for separately mixing water and fertilizer and improve the overall operation efficiency, but also solve the problems of uneven fertilization and clogging of the irrigation system.
