Description

Technical Field

[0001] This utility model relates to the field of fertilization of sandy soil, and in particular to a fertilization device for planting on sandy soil. Background Technology

[0002] Sand-covered soil planting is a unique agricultural model in the arid and semi-arid regions of Northwest my country. It involves laying a layer of sand and gravel to retain moisture, suppress weeds, and regulate soil temperature. However, because the sand and gravel layer hinders the release of soil nutrients and easily causes fertilizer loss, scientific fertilization is crucial to crop yield and quality, and also places special requirements on fertilization equipment.

[0003] Existing fertilization devices are mainly divided into three categories according to their methods: broadcasting type, which spreads fertilizer evenly on the ground surface through a broadcasting mechanism and is suitable for large-area base fertilizer; strip application type, which first digs a trench and then accurately applies fertilizer into the trench and covers it with soil, which is conducive to topdressing and reduces volatilization; and hole application type, which is for crops with large plant spacing, digs a hole at the root and applies fertilizer in a quantitative and concentrated manner to improve fertilizer utilization.

[0004] Many existing fertilization devices have limited functions, either only capable of spreading fertilizer or lacking precise fertilization and soil covering components even when they can dig trenches. This leads to a break in the operation process. Some devices fail to deliver fertilizer accurately into the trench after digging, or the soil covering after fertilization is not timely or tight, resulting in fertilizer exposure and volatilization loss. This is especially true in special conditions such as sandy soil, where fertilizer is easily washed away by water. Therefore, a fertilization device for planting in sandy soil is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a fertilization device for planting on sandy land, which aims to improve the problem that the functions of various components of the existing fertilization device for planting on sandy land are disconnected, and the fertilization device fails to achieve the integrated operation of trenching, precise fertilization and effective soil covering.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fertilization device for planting on sandy land, comprising a fertilization vehicle, a liquid storage tank fixedly connected to the fertilization vehicle, a pump body fixedly connected to the liquid storage tank, a telescopic pipe fixedly connected to the output end of the pump body via a pipeline, a long pipe fixedly connected to the bottom end of the telescopic pipe, a plurality of sets of fertilization nozzles fixedly connected to the long pipe, valves fixedly connected to the nozzles, a ditching component, a moving component, and a soil covering component on the fertilization vehicle.

[0007] As a further description of the above technical solution: The trenching assembly includes a drive motor fixed on the fertilizer applicator, a rotating shaft fixedly connected to the output end of the drive motor, a connecting rod fixedly connected to the rotating shaft, and a trenching plate fixedly connected to the connecting rod.

[0008] As a further description of the above technical solution: The trenching plate is configured as a triangle.

[0010] As a further description of the above technical solution: Both the slider and the groove are designed in a T-shape.

[0011] As a further description of the above technical solution: The soil covering assembly includes an electric push rod fixed on a fertilizer applicator. The output end of the electric push rod is fixedly connected to a push plate, and a burial plate is provided on the push plate. The burial plate has an inclined surface.

[0012] As a further description of the above technical solution: The push plate has a guide groove, and a slide block is slidably connected in the guide groove. The push plate has several sets of equidistant positioning holes, and positioning bolts are threaded into the positioning holes.

[0013] As a further description of the above technical solution: The outer wall of the slide is fixedly connected to the outer wall of the buried plate, and the positioning bolt passes through the slide and is threadedly connected to the slide.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the triangular trenching plate efficiently opens trenches, and the nozzle, driven by a small electric actuator, can be uniformly adjusted in position or oscillate along an S-shaped route for fertilization, improving the uniformity and coverage of fertilization.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 This utility model provides an embodiment of a fertilization device for planting in sandy soil, including a fertilization vehicle 1. The fertilization vehicle 1 is a motorized or towed trolley with a power source, which includes a frame, wheels, and a power system. The power system not only provides power for the movement of the vehicle body, but also provides power for the drive motor 2, pump body 7, small electric actuator 12, and electric actuator 16. The power system is a battery pack installed on the frame, or a generator driven by the power output shaft provided by the towing tractor. The frame of the fertilization vehicle 1 is welded from steel profiles and has sufficient strength and rigidity to install all functional components. The wheels can be wide tires selected according to the ground conditions to prevent sinking in the sandy soil. A liquid storage tank 6 is fixedly connected to the fertilization vehicle 1, and a pump body 7 is fixedly connected to the liquid storage tank 6. The output end of the pump body 7 is fixedly connected to a telescopic pipe 8 through a pipe. The bottom end of the telescopic pipe 8 is fixedly connected to a long pipe 9. Several sets of spray nozzles 11 for fertilization are fixedly connected to the long pipe 9, and valves 10 are fixedly connected to the spray nozzles 11.

[0020] Reference Figures 1-2 The fertilizer applicator 1 is equipped with a trenching component, which is fixed to the front of the frame of the fertilizer applicator 1 by a bracket. The trenching component includes a drive motor 2 fixed on the fertilizer applicator 1. The output end of the drive motor 2 is fixedly connected to a rotating shaft 3. A connecting rod 4 is fixedly connected to the rotating shaft 3. A trenching plate 5 is fixedly connected to the connecting rod 4. The trenching plate 5 is triangular.

[0021] Reference Figures 2-4 The fertilizer applicator 1 is equipped with a moving component. Two moving components are provided on each set of long tubes 9. The moving component includes a connecting plate 13 fixed on the long tube 9. A groove 14 is provided on the connecting plate 13. A slider 15 is slidably connected in the groove 14. Both the slider 15 and the groove 14 are T-shaped. A small electric actuator 12 is fixedly connected to the fertilizer applicator 1. When the two sets of small electric actuators 12 are activated at the same time, the position of the nozzle 11 can be adjusted. When the two sets of small electric actuators 12 are activated alternately, the long tube 9 can be tilted back and forth, so that the nozzle 11 follows an S-shaped path when applying fertilizer. The output end of the small electric actuator 12 is hinged to the slider 15.

[0022] Reference Figures 1-3 The fertilizer applicator 1 is equipped with a soil covering component. The soil covering component is fixed to the rear part of the frame of the fertilizer applicator 1 by an electric push rod 16. The soil covering component includes an electric push rod 16 fixed on the fertilizer applicator 1. A push plate 17 is fixedly connected to the output end of the electric push rod 16. A burial plate 18 is provided on the push plate 17. An inclined surface 19 is provided on the burial plate 18.

[0023] Reference Figures 3-4 The push plate 17 has a guide groove 20, and a slide block 21 is slidably connected in the guide groove 20. The outer wall of the slide block 21 is fixedly connected to the outer wall of the burial plate 18. The push plate 17 has several sets of equidistantly distributed positioning holes 22. Positioning bolts 23 are threadedly connected in the positioning holes 22. The positioning bolts 23 pass through the slide block 21 and are threadedly connected to the slide block 21.

[0024] Working principle: First, the trenching assembly is started, driving motor 2 to rotate synchronously, causing the output shaft 3 to rotate synchronously. Connecting rod 4 is linked accordingly, which in turn drives the triangular trenching plate 5 at its end to move. After moving, the triangular trenching plate 5 can break through the sand layer on the surface of the sandy soil, forming a fertilization trench that meets the planting needs, preparing for subsequent fertilization. Then, the fertilization and position adjustment system is activated. The fertilizer solution in the storage tank 6 is pressurized by pump body 7 and then transported through pipeline to telescopic pipe 8, and then flows into the telescopic pipe. The long pipe 9 connected to the bottom of the 8-section ultimately sprays the fertilizer evenly into the prepared trenches through several sets of nozzles 11 on the long pipe 9. Simultaneously, the position of the nozzles 11 can be adjusted via a movable component according to the planting row spacing or fertilization needs. If both sets of small electric actuators 12 are activated simultaneously, they drive the entire long pipe 9 to move horizontally, achieving uniform adjustment of the lateral position of the nozzles 11. If the two sets of small electric actuators 12 are activated alternately, the nozzles 11 swing back and forth, forming an S-shaped movement path during fertilization, expanding the fertilization coverage area, avoiding fertilizer accumulation, and improving efficiency. To ensure uniform fertilization, the valve 10 on the nozzle 11 can individually control the on / off state of each group of nozzles 11, facilitating flexible adjustment of the number of fertilization groups. Finally, the soil covering assembly is activated. After the electric push rod 16 is powered on, it pushes the push plate 17 to move towards the trench, and the burial plate 18 approaches the sand layer. The inclined surface 19 on the burial plate 18 guides the direction of the sand layer, covering it back to its original position, completing the soil covering operation. This prevents fertilizer from being lost due to wind and sun exposure, while also meeting the requirements for sand layer coverage in sandy soil planting. If the soil covering depth needs to be adjusted, the fixed valve can be loosened. Positioning bolt 23 pushes slide block 21 to slide within guide groove 20. After the burial plate 18 is adjusted to the appropriate height, positioning bolt 23 is tightened again. The position of slide block 21 is fixed by the threaded connection between positioning bolt 23, positioning hole 22, and slide block 21, so as to realize the flexible adjustment of the height of burial plate 18 and adapt to the soil covering requirements of trenches of different depths. Throughout the process, each component realizes the automated operation from trenching to soil covering through mechanical linkage and electronic control adjustment, which greatly improves the fertilization efficiency and accuracy of planting on sandy land and reduces the intensity of manual operation.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
