Description

Technical Field

[0001] This utility model relates to a pipe laying machine, and more particularly to a deep-buried drip irrigation tape laying mechanism. Background Technology

[0002] Currently, buried drip irrigation is a new type of high-efficiency water-saving irrigation technology. It uses buried pipeline systems and drippers installed on drip tape to deliver pressurized water in a small, uniform, and accurate flow to the soil near crop roots to meet the needs of normal crop growth. Buried drip irrigation has been widely used in agricultural production. Existing deep-buried drip tape laying mechanisms typically include a furrow opener and a laying mechanism. The furrow opener is responsible for creating furrows in the soil, while the laying mechanism places the drip tape within the furrows. However, these solutions suffer from insufficient soil-breaking ability of the furrow opener when dealing with hard soil or untilled fields, resulting in low laying efficiency. Furthermore, the drip tape can only be laid after the field has been tilled and dried. In addition, due to the lack of a precise positioning system in existing technologies, the row spacing of the laid drip tape is often inconsistent, directly affecting the uniformity and efficiency of drip irrigation. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a deep-buried drip irrigation tape laying mechanism, which has a soil-breaking device set in front of the trench opener to improve soil-breaking ability, effectively deal with hard soil, and improve laying efficiency.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] See Figures 1 to 4 This utility model discloses a deep-buried drip irrigation tape laying mechanism, comprising a furrow opener 1, a drip irrigation tape conveying device 2, a soil breaking device 3, a frame 4, a guiding device 7, and a depth limiting structure 8. A plowshare 9 is fixed to the bottom of the furrowing end of the furrow opener 1. The plowshare 9 is triangular in shape to facilitate soil breaking. The forward end of the furrow opener has a cutting edge. The top of the furrow opener is fixed to the frame 4 via a first connecting frame 5. The soil breaking device is located at the front end of the furrow opener, and the drip irrigation tape conveying device is located at the rear end of the furrow opener. The depth limiting structure 8 is located on the rear side of the drip irrigation tape conveying device. Two sets of guiding devices are provided, respectively located on both sides of the frame. The soil breaking device 3 includes a soil breaking disc 3-1, a soil breaking disc fixing frame 3-2, and a soil breaking depth adjustment mechanism. Rod 3-3 has a closed-body turnbuckle structure. One end of the soil-breaking disc fixing frame 3-2 is hinged to the trencher 1, and the other end is connected to the central shaft 3-4 of the soil-breaking disc 3-1. The central shaft 3-4 is connected to the soil-breaking disc 3-1 through a bearing. One end of the soil-breaking depth adjusting rod 3-3 is hinged to the first connecting frame 5, and the other end is hinged to the soil-breaking disc fixing frame 3-2. The soil-breaking depth is adjusted by changing the length of the soil-breaking depth adjusting rod. The soil-breaking depth is adjusted according to different soil types to minimize soil cutting friction. For example, in soft soil, the soil-breaking depth is reduced to decrease friction and improve trenching efficiency. In hard soil, the soil-breaking depth is increased to reduce trencher resistance and improve trenching efficiency.

[0020] The drip irrigation tape delivery device 2 includes a drip irrigation tape delivery pipe 2-1, a reel support 2-2, and a guide ring 2-3. The drip irrigation tape delivery pipe 2-1 is welded and fixed to the rear side of the furrow opener 1. The guide ring 2-3 is fixed to the first connecting frame 5 and located directly above the drip irrigation tape delivery pipe 2-1. The reel support 2-2 is fixed to the frame 4 and located above the guide ring 2-3. The center of the reel support is perpendicular to the center of the furrow opener and is used to suspend the drip irrigation tape reel. The drip irrigation tape extends through the guide ring and enters the drip irrigation tape delivery pipe, and is buried in the furrow opened from the rear of the furrow opener. Guide rings are provided on both sides of the frame. The laying mechanism includes a fixed tube 7-1, a telescopic tube 7-2, a guide wheel 7-3, a rotating tube 7-4, and a slot 7-5. The rotating tube 7-4 is located at the end of the frame 4 and can rotate. The fixed tube 7-1 is perpendicularly connected to one end of the rotating tube 7-4. The rotation of the rotating tube causes the fixed tube to be in a horizontal or vertical position. The slot 7-5 is located on the frame at the connection end between the fixed tube and the rotating tube. The telescopic tube 7-2 is sleeved in the fixed tube. The guide wheel 7-3 is located at the end of the telescopic tube. The distance from the guide wheel to the trencher is set by extending or retracting the telescopic tube. During operation, the rotating tube is rotated to place the fixed tube horizontally for precise positioning of the trenching spacing. When stopping operation, the rotating tube is rotated again to retract the fixed tube to the vertical direction and engage it through the slot. The frame 4 is connected to the traction mechanism through a bracket 6, which drives the entire laying mechanism forward.

[0021] The depth limiting structure 8 is fixed to the rear frame of the furrow opener 1. The depth limiting structure 8 includes a depth limiting wheel 8-1, a depth adjusting rod 8-2, an adjusting frame 8-3, and a second connecting frame 8-4. The second connecting frame 8-4 is fixed to the frame 4. The depth limiting wheel 8-1 is axially connected to the lower end of the adjusting frame 8-3. One end of the depth adjusting rod 8-2 is hinged to the lower end of the adjusting frame 8-3, and the other end is movably connected to the upper end of the second connecting frame 8-4. The adjusting frame 8-3 is hinged to the second connecting frame 8-4. The depth adjusting rod 8-2 has a closed-body turnbuckle structure. The height of the depth limiting wheel is controlled by the depth adjusting rod, thereby controlling the depth at which the furrow opener lays the drip irrigation tape.

[0022] Working Process: An agricultural tractor suspends the laying mechanism, pre-plans the furrowing positions in the work area, and lays a steel wire. The drip irrigation tape reel is installed, and the guide wheels are placed horizontally. The spacing between the furrow openers and between the guide wheels and the furrow openers is adjusted to ensure equal spacing. The tractor, with the pipe-laying machine suspended parallel to the steel wire, moves forward, with the guide wheels aligned with the steel wire. Under traction, the soil-breaking disc first breaks the soil to create a crack, and then the furrow openers break deeper into the soil. The depth-limiting wheel controls the laying depth, and the drip irrigation tape is evenly laid on the designated furrow line. After completing one furrow line, the tractor can turn to work on the next furrow line, repeating the process until the entire field is covered with drip irrigation tape. Throughout the process, the operator can optimize the furrowing depth and drip irrigation tape laying depth by adjusting the soil-breaking depth adjustment rod and the depth-limiting wheel according to the actual soil conditions and crop planting needs to achieve the best irrigation effect. In addition, on untilled plots, the soil-breaking disc can also cut off surface weeds, branches and other debris to prevent them from affecting the normal operation of the furrow opener.
