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 processes, such as desertification control and saline-alkali land improvement, it is often necessary to evenly spread fertilizers and soil conditioners (such as coal gangue solid-liquid mixtures) onto the land. Traditional spreading methods often have many shortcomings. For example, manual sowing is not only labor-intensive and inefficient, but it is also difficult to ensure uniformity of application, easily leading to localized over- or under-fertilization, which affects crop growth or the effectiveness of land management.

[0003] While some existing trenching equipment can create trenches in the land, they lack effective spreading devices to complement them. These devices simply perform the trenching action, requiring subsequent spreading operations by additional equipment or manual labor, increasing the complexity and cost of the process. Furthermore, even equipment that combines trenching and spreading functions may suffer from issues such as unadjustable trench depth, uneven spreading, and poor adaptability to different types of materials. For example, existing equipment may not be able to accurately deliver highly viscous liquid fertilizers or solid-liquid mixtures into the trenches and ensure uniform spreading.

[0004] With the advancement of agricultural modernization and the increasing importance of land management, the demand for a device capable of efficient and precise trenching and spreading operations is becoming increasingly urgent. This device needs to be adaptable to different land conditions and operational requirements, improving the uniformity and accuracy of spreading while reducing labor intensity and operating costs to meet the needs of modern agricultural production and land management. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a trenching and spreading device, including a trenching and spreading vehicle. The trenching and spreading vehicle is equipped with a perforated tow wheel at its rear. The perforated tow wheel includes a wheel body, and multiple rows of insert rods communicating with a feeding pipe are arranged at intervals on the rim of the wheel body.

[0006] Furthermore, the perforated tow wheel 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 perforated tow wheel relative to the ground, and thus adjusting the depth of the insertion hole.

[0007] Furthermore, the trenching and spreading vehicle includes three independent perforated tugs.

[0008] Furthermore, a furrowing plowshare is installed in front of the perforated tugboat.

[0009] Furthermore, two, four, or six rows of perforated inserts are provided on the rim of the wheel body.

[0010] Furthermore, the front end of the perforated insertion rod is provided with a floating plug, which is connected to the feeding pipe by a spring and can float up and down on the feeding pipe. The floating plug is provided with an opening and closing hole, and the feeding pipe is provided with a liquid outlet. When the floating plug is inserted downward into the soil, the floating plug compresses the spring and floats upward, so the opening and closing hole opens relative to the liquid outlet, and the liquid from the feeding pipe is injected into the insertion hole.

[0011] This invention achieves integrated ditching and spreading operations by installing a perforated tow wheel at the rear of the ditching and spreading vehicle. While the vehicle is in motion, it can simultaneously complete ditching and inject liquid fertilizer or other materials into the ditch, greatly improving work efficiency and reducing working time and labor costs.

[0012] The inserter on the perforated tractor inserts evenly into the ground to form holes as the wheel rotates. The design of the floating plug at the front end of the inserter and the feeding pipe ensures accurate liquid injection into the holes. This design results in more even application, avoiding localized over- or under-fertilization, and promotes uniform crop growth and balanced soil improvement.

[0013] The perforated tow wheel is mounted on the vehicle's main frame via a connecting arm. The angle of the connecting arm can be adjusted via a threaded adjustment handle, thereby adjusting the height of the perforated tow wheel relative to the ground and thus adjusting the depth of the perforation (i.e., the trenching depth). This adjustability allows the device to adapt to different crop planting needs and land conditions. For example, a shallower trenching depth can be used for shallow-rooted crops, while a deeper trenching depth can be appropriately increased for deep-rooted crops.

[0014] The device can adapt to materials of different viscosities and properties by adjusting parameters such as the pressure or flow rate of the feed pipe. For thinner liquid fertilizers, a lower pressure and a higher flow rate can be used for application; for more viscous solid-liquid mixtures such as coal gangue, the pressure can be appropriately increased to ensure that the material can pass smoothly through the feed pipe and the injection rod into the injection hole.
