Detailed Implementation

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments: refer to Figure 1-2 As shown, this utility model provides an intelligent integrated machine for trenching, pipe laying, and backfilling of deep-buried drip irrigation systems. It includes: a suspension frame 1, with an adjustment mechanism hinged to its front end and a pressing mechanism hinged to its rear end; a first hydraulic cylinder 2 hinged to the top of the front end of the suspension frame 1, which is hinged to the pressing mechanism; multiple trenching cutter discs 3 rotatably mounted below the suspension frame 1; a transmission gearbox 4 positioned directly above the trenching cutter discs 3 on the suspension frame 1; the input end of the transmission gearbox 4 connected to the rear output shaft of a tractor via a universal joint; and the output end of the transmission gearbox 4 connected to the drive shaft of the trenching cutter discs 3 via a bevel gear pair; multiple trenching cutters 5 fixed to the bottom of the rear end of the suspension frame 1; and a pipe laying mechanism positioned directly above the trenching cutters 5 on the suspension frame 1. By integrating trenching, pipe laying, and backfilling into one unit, the problem of low efficiency and high cost associated with segmented operations is solved, enabling continuous and rapid drip irrigation tape laying.

[0017] In a preferred embodiment, the suspension frame 1 includes: a horizontal frame, a vertical frame welded to the middle of the front end of the horizontal frame, first hinge seats 6 installed on both sides of the front end of the horizontal frame, and a second hinge seat 7 installed at the middle of the top end of the vertical frame.

[0018] In a preferred embodiment, the adjustment mechanism includes two second hydraulic cylinders 8, one end of which is hinged to the tractor and the other end to a connecting plate 9, the other end of which is hinged to a first hinge seat 6. The adjustment mechanism also includes a third hydraulic cylinder 10, one end of which is hinged to the tractor and the other end to the front end of the second hinge seat 7. The second hydraulic cylinders 8 are mainly used to adjust the height of the suspension frame 1, and the third hydraulic cylinder 10 is mainly used to adjust the angle of the suspension frame 1, thereby controlling the trenching depth (25-30cm) and ensuring consistent depth. The trenching cutter head 3 is designed to adaptively match the soil hardness. An angle sensor is installed on the suspension frame 1 to detect the angle value of the trenching cutter head 3. Simultaneously, the control system monitors the extension and retraction distance of the second hydraulic cylinders 8 to control the depth, ensuring that the trenching depth error of the trenching cutter head 3 is ≤±5mm.

[0019] In a preferred embodiment, the compaction mechanism includes a backfill wheel bracket 11, which is hinged to one end of a first hydraulic cylinder 2, and the other end of the first hydraulic cylinder 2 is hinged to the rear end of a second hinge seat 7. A backfill compaction wheel 12 is installed at the bottom of the backfill wheel bracket 11. The backfill wheel bracket 11 includes a first frame and a second frame, both of which are hinged to the rear end of a horizontal frame. A sliding sleeve is hinged to the rear end of the first frame, and a connecting rod is hinged to the rear end of the second frame. The connecting rod is slidably disposed within the sliding sleeve. A backfill pressure spring 13 is sleeved on the connecting rod between the sliding sleeve and the second frame. Several insertion holes are provided on the side wall of the connecting rod, and each insertion hole is fitted with a limit pin. The trenched soil is backfilled and compacted by the backfill compaction wheel 12. The compaction pressure is adjusted by the backfill wheel bracket 11 and the backfill pressure spring 13 to ensure a backfill compaction degree ≥90%. The first hydraulic cylinder 2 mainly controls the backfill compactor wheel 12 to rise and fall before and after trenching, preventing it from scraping the road surface when entering the field.

[0020] In a preferred embodiment, the pipe laying mechanism includes: a drip irrigation tape reel 14, on which drip irrigation tape 15 is wound; a drip irrigation tape guide wheel 16 is provided on the support of the drip irrigation tape reel 14; a channel is provided inside the furrowing knife 5; a closed-loop control guide wheel 17 is installed in the channel; the drip irrigation tape 15 is guided by the drip irrigation tape guide wheel 16 and passes between the closed-loop control guide wheels 17, finally extending out from the bottom of the furrowing knife 5. The drip irrigation tape 15 is mounted on the drip irrigation tape reel 14 and enters the channel of the furrowing knife 5 through the closed-loop control guide wheel 17. The depth of the furrowing knife 5 is controlled by an angle sensor. The drip irrigation tape 15 is buried in the soil by soil friction. The closed-loop control guide wheel 17 ensures that the dripper of the drip irrigation tape 15 is facing upwards. The laying depth is monitored by an angle sensor and a hydraulic cylinder distance sensor, and the laying error is ≤±1mm.

[0021] In a preferred embodiment, a trenching guide cover 18 is installed above the trenching cutter head 3.

[0022] As a preferred embodiment, it also includes: GNSS-RTK high-precision path planning, integrated RTK positioning (accuracy ±2cm) and IMU inertial navigation, preset farmland boundaries and drip irrigation tape 15 wiring paths, and supports automatic obstacle avoidance.

[0023] The working process and principle of this utility model are as follows: The intelligent deep-buried drip irrigation trenching, pipe laying, and backfilling integrated machine has four main functions: First, it uses a tractor as its power source. The tractor's power output shaft transmits power to the transmission gearbox 4, which drives the trenching cutter head 3 to open trenches. The trench width is 4cm, and the trenching depth is monitored by angle and displacement sensors. The data is fed back to the central controller in the cab for algorithm processing and then transmitted to the hydraulic cylinder solenoid valve for execution, controlling the depth to be between 25-30cm. Second, it buries the drip irrigation tape. The drip irrigation tape 15 is laid in the soil through the drip irrigation tape wheel 14, with the direction of the drip irrigation tape 15 monitored. After the drip irrigation tape guide wheel 16, it enters the closed-loop control guide wheel 17 and the trenching cutter head 5 channel. The drip irrigation tape 15 is laid in the soil by soil friction, with the depth controlled within a laying error of ≤±1mm. Third, it uses the backfilling and compaction wheel 12 to backfill and compact the trenched soil. The compaction hardness is adjusted by the backfilling pressure spring 13. Fourth, it integrates RTK positioning (accuracy ±2cm) and IMU inertial navigation, presets farmland boundaries and drip irrigation tape wiring paths, and supports automatic obstacle avoidance (millimeter-wave radar + ultrasonic sensors).
