Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural equipment especially ditching and spreading device. BACKGROUND

[0002] In the field of agricultural production and land management, ditching and spreading operation is an important operation link. The traditional ditching and spreading method has many problems.

[0003] On the one hand, for ditching operation, the common method is to use a separate ditching plow to form a transverse trench, which is low in efficiency and difficult to cooperate with subsequent spreading operation. In actual operation, ditching is completed first, and then spreading is carried out, which not only has a complicated process, but also is difficult to ensure the accuracy of the spreading position due to the time difference and operation error between the two operations, which may cause the fertilizer or modifier to deviate from the trench position, affecting its effect.

[0004] On the other hand, in the spreading link, traditional manual spreading or simple mechanical spreading equipment often cannot achieve uniform and accurate spreading. Manual spreading has high labor intensity and poor uniformity, and some simple mechanical spreading devices may not be able to be flexibly adjusted according to different land conditions and crop needs, resulting in inaccurate spreading amount and position. For example, different soil textures and terrain conditions require different depths and widths of trenches and appropriate spreading amounts, and traditional equipment cannot meet these diversified needs.

[0005] In addition, in special land management projects such as desertification control and saline-alkali land improvement, the precision and efficiency of ditching and spreading are required to be higher. Traditional equipment cannot effectively deal with complex land conditions such as loose texture of sand and special soil structure of saline-alkali land when dealing with ditching and spreading operation under these special conditions, resulting in unsatisfactory management effect and waste of a large amount of manpower, material resources and financial resources.

[0006] Therefore, there is an urgent need for a device that can efficiently and accurately perform ditching and spreading operation and adapt to different land conditions and operation needs to improve agricultural production efficiency and land management effect. SUMMARY

[0007] To achieve the above-mentioned purpose, the utility model provides a kind of ditching and spreading device, including ditching and spreading car, the ditching and spreading car is provided with opening drag wheel in tail part, the opening drag wheel includes wheel body, and multiple rows of transverse ditching blades are arranged on the wheel rim of wheel body and communicated with feeding pipe.

[0008] Further, the transverse ditching drag wheel is installed on the body frame of the ditching and spreading car through the connecting arm, and the angle of the connecting arm can be adjusted through the threaded adjusting handle, so as to adjust the height of the transverse ditching drag wheel relative to the ground, and further adjust the depth of the transverse trench.

[0009] Further, the furrower includes three independent lateral furrowing pulleys.

[0010] Further, the lateral furrowing pulley is further provided with a row of furrowing share.

[0011] Further, two rows, four rows or six rows of lateral furrowing blades are arranged on the rim of the wheel body.

[0012] Further, the lateral furrowing blade is provided with an injection groove; the lateral furrowing blade is floatingly installed on the feeding pipe through a spring; the feeding pipe is provided with an opening and closing hole; when the lateral furrowing blade is inserted into the soil, the spring is compressed and the opening and closing hole is opened, so that the liquid from the feeding pipe flows into the lateral furrow through the injection groove.

[0013] Technical effects

[0014] Precise furrowing and spreading

[0015] The device realizes the synchronization of furrowing and spreading by arranging the lateral furrowing pulley at the tail of the furrower. The lateral furrowing blade can accurately open a lateral furrow on the ground when the wheel body rotates, and is connected with the feeding pipe to ensure that the fertilizer or other materials can be directly and accurately spread into the furrow, greatly improving the accuracy of spreading and avoiding waste and misapplication of materials.

[0016] The injection groove on the lateral furrowing blade and the cooperation of the opening and closing hole and the spring on the feeding pipe ensure that the opening and closing hole can be opened in time when the lateral furrowing blade is inserted into the soil, and the liquid material can flow uniformly into the furrow through the injection groove, further ensuring the uniformity of spreading and being beneficial to the uniform absorption of nutrients by crop roots or the uniform improvement of the soil.

[0017] Height adjustment to meet various needs

[0018] The lateral furrowing pulley is installed on the body frame of the vehicle through the connecting arm and the threaded adjusting handle, which can conveniently adjust the angle of the connecting arm and accurately adjust the height of the lateral furrowing pulley relative to the ground. This design enables the device to flexibly adjust the depth of the lateral furrow according to the root growth characteristics of different crops and the soil conditions, such as setting a shallower furrow for shallow-rooted crops and deepening the furrow for deep-rooted crops, to meet different planting and management needs.

[0019] Improving work efficiency

[0020] The ditching and spreading vehicle is equipped with three independent transverse ditching drag wheels, and a row of ditching share is arranged in front of the vehicle, in the process of traveling, the ditching share first opens a longitudinal ditch, and the transverse ditching drag wheel then opens a transverse ditch and spreads the material, thereby completing the complex ditching and spreading operation mode at one time, significantly improving the operation efficiency, reducing the operation time and labor cost, and being especially suitable for large-area farmland operation and land management engineering.

[0021] Wide applicability

[0022] Different numbers of configurations such as two rows, four rows or six rows of transverse ditching blades can be arranged on the wheel rim of the wheel body, so that different spreading amounts and land condition requirements can be adapted. Whether it is fertilizer spreading in ordinary farmland, coal gangue solid-liquid mixture spreading in desert management, or special agent spreading in saline-alkali land improvement, etc., the ideal operation effect can be achieved by adjusting the number of transverse ditching blades and other parameters, and the application range is wide.
