Description

Technical Field

[0001] This utility model relates to the technical field of agricultural machinery and media conveying equipment, and in particular to a deep loosening and deep application conveying system for dual-media collaborative operation. Background Technology

[0002] In the field of agricultural cultivation, long-term continuous cropping and traditional farming methods lead to soil compaction and shallow topsoil, hindering crop root development, reducing nutrient absorption efficiency, and restricting sustainable agricultural development. To promote conservation tillage with deep plowing and deep application, soil loosening technology based on the principle of air pressure and hollow drill rod deep application technology have emerged.

[0003] Existing deep tillage and deep soil loosening devices can transport high-pressure gas or fertilizer through a single channel, but they have the following shortcomings: they cannot simultaneously achieve the coordinated transport of two media, and their function is relatively limited. They cannot meet the growing demand in modern agriculture for coordinated dual-media operations such as "soil loosening + fertilization" and "disinfection + nutrient supplementation." Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a dual-media collaborative deep loosening and deep application conveying system. The system's dual-cavity conveying pipeline adopts a concentric dual-cavity structure design and is threadedly connected to an integrated spraying unit. Furthermore, the flow rate and ratio of the two media can be adjusted manually via valve groups according to specific operational needs, enabling independent conveying and collaborative operation of gas and liquid. This meets the combined requirements of "soil loosening + fertilization" and "disinfection + nutrient supplementation," and the pipeline and valve group are securely connected, ensuring stable performance and adaptability to diverse deep loosening and deep application requirements in farmland.

[0005] This utility model is achieved through the following technical solution.

[0006] A deep loosening and deep application conveying system for dual-media collaborative operation includes an integrally formed dual-cavity conveying pipe and an integrated spraying unit. The two are assembled by a sealing threaded section and a connecting internal thread. The dual-cavity conveying pipe has concentric dual-cavity channels along the axial direction. The inner pipe is a liquid channel, and the space between the outer pipe and the inner pipe is a gas channel. The integrated spraying unit has four liquid spray holes and gas spray holes arranged alternately around its side wall. The included angle between adjacent side holes is 90°, and each side hole is connected to a corresponding dual-cavity channel. The manual valve group has independent gas regulating valves and liquid regulating valves, which are respectively connected to the dual-cavity channels. By adjusting the valve opening, collaborative operation with different media ratios can be achieved.

[0007] Furthermore, when the gas regulating valve is opened to its maximum and the liquid regulating valve is closed, pure gas blasting soil loosening operation is achieved.

[0008] Furthermore, when the liquid regulating valve is opened to its maximum and the gas regulating valve is closed, pure liquid deep application operation can be achieved.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] (1) The dual-cavity conveying pipeline adopts a concentric dual-cavity structure. The inner pipe conveys liquid and the outer pipe conveys gas. According to the operation requirements, the manual valve group can be adjusted appropriately by observing the pressure gauge to realize pure gas blasting loosening, pure liquid deep application or gas-liquid synergistic operation of different proportions. It not only meets the deep needs of soil improvement and nutrient supplementation, but also flexibly adapts to diverse farmland operation scenarios, effectively avoiding the functional limitations of traditional single-medium conveying devices.

[0011] (2) The dual-cavity conveying pipeline and the integrated spraying unit are assembled by the sealing thread section and the connecting internal thread. The threaded connection is tight and easy to reinforce with tools, which makes the air tightness and liquid tightness of the connection better. It can be used for the coordinated conveying of high-pressure gas and liquid, avoiding media leakage, reducing energy consumption and material waste, and at the same time, the appropriate integrated spraying unit can be replaced according to different operating scenarios.

[0012] (3) The gas feed pipe and liquid feed pipe, the dual-cavity conveying pipe, and the side holes of the integrated spraying unit form a complete and sealed dual-medium conveying channel. The conical nozzle of the integrated spraying unit can be manually or mechanically inserted vertically into the soil surface 600-800mm below the surface. Only a small hole with a diameter of ≤30mm is left at the insertion point, and it can close naturally after operation. The medium diffuses into the deep layer through the spraying hole on the side wall of the nozzle. There is no need to turn over the surface soil, which can maintain its structural integrity. Gas and liquid are simultaneously or separately delivered to the deep soil without damaging the surface soil.

[0013] (4) The system has a high degree of integration and is suitable for various agricultural operation scenarios, reducing equipment purchase and maintenance costs. Attached Figure Description

[0018] Reference Figure 1 , Figure 3 and Figure 4 A deep loosening and deep application conveying system for dual-media collaborative operation includes an integrally formed dual-cavity conveying pipe (2) and an integrated spraying unit (1). The two are assembled by a sealing thread section (3) and a connecting internal thread (4). The dual-cavity conveying pipe (2) is provided with concentric dual-cavity channels along the axial direction. The inner pipe is a liquid channel (21), and the outer pipe is a gas channel (22) between the inner pipe and the outer pipe. The conical nozzle (11) of the integrated spraying unit (1) has two liquid spray holes (12) and two gas spray holes (13) alternately distributed on the side wall in the circumference. Each spray hole is connected to the corresponding channel. The manual valve group (5) is provided with an independent gas regulating valve (51) and a liquid regulating valve (52), which are respectively connected to the gas feed pipe (6) and the liquid feed pipe (7).

[0019] One end of the dual-cavity conveying pipe (2) is provided with a connection port that matches the manual valve group (5), and the other end is connected to the integrated spraying unit (1) through the sealing thread section (3). The connection is tight and the performance is stable. By adjusting the valve opening of the manual valve group (5), the coordinated operation of "loosening soil and fertilizing" can be realized.

[0020] The bottom of the cone-shaped nozzle (11) of the integrated spray unit (1) is a cone-shaped structure, which makes it easy to insert into the soil.

[0021] To achieve the function of "loosening soil and applying fertilizer", the gas regulating valve (51) is adjusted to 60%-80% opening and the liquid regulating valve (52) is adjusted to 30%-50% opening, so that the high-pressure gas and liquid compound fertilizer are transported in a suitable ratio. The gas-liquid mixed mist is formed through the injection hole. It is suitable for deep soil loosening and topdressing of dryland crops such as corn and soybeans during the seedling stage, as well as for improving and supplementing nutrient in cultivated land that has been compacted due to long-term continuous cropping. While the high-pressure gas breaks up the soil plow layer, the liquid compound fertilizer is evenly penetrated into the crop root distribution area with the airflow, thereby improving the fertilizer utilization rate.

[0022] Example 2

[0023] This embodiment is basically the same as embodiment 1, except that the medium type and valve adjustment method are changed. The process is as follows: the liquid feed pipe (7) is connected to the liquid organic fertilizer and bactericide mixture storage tank, the gas feed pipe (6) is connected to the high-pressure air source, and the gas regulating valve (51) is adjusted to 50%-70% opening and the liquid regulating valve (52) is adjusted to 40%-60% opening, so that the high-pressure air and the mixture are transported in a suitable ratio to achieve the "disinfection + nutrient supplementation" operation.

[0024] This utility model patent is applicable to scenarios such as soil disinfection and base fertilizer supplementation before vegetable greenhouse planting, sterilization and fertility enhancement of planting plots for crops such as potatoes that are susceptible to soil-borne diseases, and soil treatment and nutrient supply in rice seedling fields. High-pressure air helps the mixed liquid diffuse in the soil, which not only plays a role in sterilization and disinfection, but also provides sufficient nutrients for crop growth and reduces the number of fertilizations in the later stage.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
