Description

Technical Field

[0001] This utility model relates to agricultural equipment, and more particularly to a trenching and spreading device. Background Technology

[0002] In agricultural production and land management, fertilization and material application are crucial for improving soil fertility and land conditions. However, traditional application methods often have several drawbacks. For example, fertilizer is typically simply spread on the soil surface, which makes it difficult to distribute the fertilizer evenly, resulting in low fertilizer utilization. This not only increases production costs but can also damage crops due to excessively high local fertilizer concentrations, affecting crop growth and quality.

[0003] The application of materials such as coal gangue solid-liquid mixtures also presents challenges in the process of desert or saline-alkali land remediation. If these materials are not thoroughly mixed with the soil, they cannot effectively improve soil structure and regulate soil pH, making it difficult to achieve the expected remediation results.

[0004] Moreover, some existing spreading equipment has relatively simple functions and lacks effective mixing and depth adjustment mechanisms. When faced with different types of soil, different spreading materials, and diverse operating environments, it is impossible to flexibly adjust parameters such as the depth and range of spreading and mixing, making it difficult to meet complex and ever-changing actual needs and seriously restricting the efficiency and quality improvement of agricultural production and land management. Utility Model Content

[0005] In view of the above problems, the present invention provides a trenching and spreading device, including a trenching and spreading vehicle, wherein the trenching and spreading vehicle is provided with a mixing trolley at the rear, the mixing trolley includes a wheel body, and multiple rows of mixing impellers are arranged at intervals on the rim of the wheel body.

[0006] Furthermore, the mixing trailer is mounted on the main frame of the trenching and spreading vehicle via a connecting arm, and the angle of the connecting arm can be adjusted via a threaded adjustment handle, thereby adjusting the height of the mixing trailer relative to the ground and thus adjusting the mixing depth.

[0007] Furthermore, the deflection angles of each stirring blade are staggered.

[0008] Furthermore, the mixing and spreading vehicle includes three independent mixing trolleys.

[0009] Furthermore, a ditching plowshare is installed in front of the perforated tugboat, and an infusion pipe is installed behind the ditching plowshare.

[0010] Furthermore, four, six, or eight rows of stirring impellers are arranged on the rim of the wheel body.

[0011] Technical effect

[0012] In terms of mixing effect, the mixing impeller has multiple rows of impellers on its wheel rim, and the deflection angles of the impeller blades are staggered. When the mixing impeller rotates, it can fully and efficiently mix the soil and fertilizer liquid. Compared with traditional spreading methods, it greatly improves the uniformity of material mixing with soil, ensures that fertilizer or other spreaders are evenly distributed in the soil, effectively enhances their effect, provides a more favorable soil environment for crop growth, or promotes better performance of soil amendments in land management.

[0013] In terms of depth adjustment, the mixing tow wheel is mounted on the main frame of the trenching and spreading vehicle via a connecting arm. The angle of the connecting arm can be adjusted using a threaded adjustment handle, allowing for flexible adjustment of the mixing tow wheel's height relative to the ground and precise control of the mixing depth. This enables the device to adapt to different soil types and varying spreading depth requirements. Whether for shallow surface soil fertilization or land improvement operations requiring deep mixing, it performs well, enhancing the device's applicability and practicality.

[0014] In terms of spreading efficiency, the design of the mixing tugboat, combined with the overall structure of the trenching spreading vehicle, is suitable for large-volume spreading operations. The coordinated operation of multiple independent mixing tugboats (such as three) significantly increases the spreading and mixing area per unit time, substantially improving operational efficiency and reducing operating time and labor costs. This offers clear advantages in large-scale agricultural production or large-area land reclamation projects.

[0015] Furthermore, by installing a ditching plow at the front end of the device and a liquid delivery pipe behind it, an integrated operation process of ditching, spreading, and mixing is achieved. The ditching plow pre-treats the soil, creating favorable conditions for subsequent material spreading and mixing. The liquid delivery pipe accurately transports liquid materials to designated locations, further optimizing the entire spreading operation process, improving the accuracy and continuity of the operation, and powerfully promoting the development and progress of spreading technology in the fields of agriculture and land management.
