Description

Technical Field

[0001] The invention belongs to the technical field of agricultural irrigation, and in particular relates to a deep-buried drip irrigation belt laying device for an anti-turnover belt. Background Art

[0002] With the advancement of modern agricultural facilities and irrigation technology, underground drip irrigation has become one of the internationally recognized high-efficiency irrigation technologies due to its significant advantages in water conservation, yield increase, energy conservation, and soil environment improvement. However, the existing drip irrigation tape laying device still has certain limitations:

[0003] First, the laying depth is shallow, which makes it difficult to meet the needs of deep irrigation; second, the guide belt device usually adopts a guide wheel with a triangular arc block and a rotating wheel structure. Due to the limited contact area between the guide wheel and the drip irrigation belt, the control force is insufficient, and the belt is prone to streamer and flipping during operation. The surface of the drip irrigation belt may even be scratched due to friction, affecting the laying quality and irrigation effect.

The device can be used in farmland with narrow working space and small cultivated area under human power, solving the problem of strong working space limitation in the prior art. 2. By arranging multiple supporting brackets on the drip irrigation tape, the drip irrigation tape can be supported after being buried in the soil of the farmland, preventing the drip irrigation tape from being flattened after being buried in the soil. The large difference in water pressure between the inner cavity of the drip irrigation tape head end and the inner cavity of the drip irrigation tape tail end during irrigation causes the drip irrigation tape to have a poor irrigation effect. Moreover, when the drip irrigation tape is wound, the supporting bracket will also deform, causing the drip irrigation tape to be in a flattened state, thereby saving storage space for the drip irrigation tape and enhancing the practicality of the device. 3.

Compared with the existing technology, the scheme provides a drip irrigation tape laying device for cultivation. The support plate connected to the tail of the trencher and the column of the laying assembly are used in conjunction, so that the drip irrigation tape is coiled and rotated to release the compressed drip irrigation tape into an expanded state. The inclined first guide tube is used to guide the expanded drip irrigation tape into the trench excavated by the trencher, and then the horizontal second guide tube is used to prevent the drip irrigation tape from tipping to both sides after entering the trench, so that the drip irrigation tape can be conveniently buried with soil to keep it in an expanded state. At the same time, most of the soil is distributed on both sides of the compressed drip irrigation tape, so that the gravity of the soil is not applied to the drip irrigation tape. The drip irrigation tape can slowly return to its original state by using its own elasticity, so as to avoid wasting a lot of water and time to expand the drip irrigation tape, thereby improving the convenience of using the drip irrigation tape. The scheme has good effect, is easy to use, has strong practicality, and is worthy of promotion. A drip irrigation tape laying machine includes a frame; a traction frame is fixed to the front end of the frame; a contour wheel is rotatably provided at the bottom of the frame; a drip irrigation tape roller is rotatably provided on the frame; a drip irrigation tape conveying mechanism is fixed to the frame and is placed below the drip irrigation tape roller; a cutting mechanism fixed to the frame is provided below the drip irrigation tape conveying mechanism; the end of the drip irrigation tape on the drip irrigation tape roller passes through the drip irrigation tape conveying mechanism and the cutting portion of the cutting mechanism in sequence.

The shearing mechanism includes a base, a reduction motor and a shearing part placed under the base; the base is fixed on the frame below the drip irrigation belt conveyor mechanism, the reduction motor is fixed on the top surface of the base, and the output shaft of the reduction motor passes through the base and is connected to the shearing part.The cutting part is a horizontally arranged pair of scissors, comprising a fixed part, a movable part, and an articulated shaft. The top end of the articulated shaft is coaxially connected to the output shaft of the reduction motor. A clamping block is coaxially mounted on the articulated shaft, and a movable part is mounted on the clamping block. A fixed part is mounted on the articulated shaft below the movable part, and the fixed part and the movable part are fitted together. The blades of the fixed part and the movable part are respectively placed on either side of the outlet of the drip irrigation tape conveyor mechanism, and the handle of the fixed part is fixedly connected to the base. The bottom end of the articulated shaft is placed below the fixed part and is coaxially threaded with a tightening bolt. A compression spring is mounted on the articulated shaft between the nut of the tightening bolt and the fixed part. The two ends of the compression spring respectively abut the nut of the tightening bolt and the fixed part. The handle of the fixed part is fixedly connected to the base via a pin. The system also includes a contact encoder and a controller. The contact encoder is mounted on a frame. The encoder's signal input is coaxially mounted with a friction wheel that rolls in contact with the contoured wheel's axle. The encoder's output is electrically connected to the controller's input, which in turn is electrically connected to the drip irrigation tape conveyor's drive motor and the shearing mechanism's reduction motor. A downwardly extending drip irrigation tape guide trough is mounted on the frame below the shearing mechanism. The top notch of the trough aligns with the tape outlet of the drip irrigation tape conveyor. A bulldozer is mounted at the front bottom of the frame. The advantages of this solution are as follows: during the traction process of the traction equipment, the drip irrigation tape sandwiched between the driving belt and the driven belt is conveyed downward by the friction between the driving belt and the driven belt. When a row of laying is completed, the reduction motor of the shearing mechanism is started, and the blade of the movable part is close to the blade of the fixed part to cut the drip irrigation tape, thereby completing the laying of a row of drip irrigation tape. Such reciprocating action can realize the laying of a large number of drip irrigation tapes. The laying of the drip irrigation tape is actively conveyed downward by the interaction between the driving belt and the driven belt, rather than passively pulling and laying, so as to avoid breaking the drip irrigation tape; and the drip irrigation tape is cut by the shearing mechanism, which reduces labor intensity and improves work efficiency.
