Description

Technical Field

[0001] This utility model relates to a device for laying deeply buried drip irrigation pipes, belonging to the technical field of agricultural machinery and equipment. Background Technology

[0002] Buried drip irrigation pipes, as an advanced irrigation technology, have been widely used in agriculture worldwide. With the increasing severity of global climate change and water scarcity, improving irrigation efficiency and conserving water resources have become crucial for sustainable agricultural development. In China, with the acceleration of agricultural modernization, the demand for efficient water-saving irrigation technologies is growing. Buried drip irrigation pipes, due to their water-saving, energy-saving, and fertilizer-saving characteristics, are gradually becoming an important direction for agricultural irrigation technology innovation in my country. Currently, my country widely adopts no-till seeding technology, which involves direct fertilization and sowing on uncultivated land, reducing the number of times agricultural machinery needs to enter the field, simplifying operational procedures, and lowering operating costs.

[0003] No-till seeding technology, under existing land resources, avoids tilling the farmland during agricultural production. Instead, straw is returned to the field to cover the soil surface, preventing soil erosion and wind damage, while increasing soil moisture retention and drought resistance. Deep-buried drip irrigation pipes are laid before crop planting, at a depth of 300-500mm. Using integrated equipment for trenching, pipe delivery, laying, and burying, the drip irrigation pipes are laid in the field to prevent damage during later sowing operations. Deep-buried drip irrigation pipes have a lifespan of 5-8 years or more, significantly reducing production costs.

[0004] When existing drip irrigation pipe laying devices are used on uncultivated land, the ditching resistance is high, and the surface weeds and roots are seriously entangled, affecting the ditching efficiency; the laying depth is uneven, resulting in unstable drip irrigation effect. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a deep-buried drip irrigation pipe laying device. By optimizing the trenching mechanism and laying device, it significantly improves laying efficiency and depth uniformity, ensures irrigation effect, and promotes efficient agricultural production.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A deep-buried drip irrigation pipe laying device includes a furrow opener, depth limiting wheels, a pipe laying device, a depth adjustment device, and a controller. The furrow opener has a vertically arranged depth adjustment groove. Two depth limiting wheels are provided, each fixed to one end of a depth limiting wheel axle passing through the depth adjustment groove. The depth adjustment device includes an electric push rod and an ultrasonic rangefinder. Two electric push rods are provided, each located on one side of the furrow opener. The top end of each electric push rod is fixed to a fixing slot at the top of the furrow opener, and the bottom end is connected to the depth limiting wheel axle. The ultrasonic rangefinder is fixed above the cutting edge of the furrow opener via a ranging bracket. The pipe laying device is located at the opposite end of the cutting edge of the furrow opener. The controller is electrically connected to the electric push rods and the ultrasonic rangefinder.

[0007] In the aforementioned deep-buried drip irrigation pipe laying device, two rotary cutting blades are fixed on the depth-limiting wheel shaft, respectively located on both sides of the furrow opener. Each rotary cutting blade is located between the furrow opener and the electric push rod. The rotary cutting blade includes three sickle-shaped impellers, a fixing sleeve, and a locking screw. The fixing sleeve is fixed to one side of the intermediate shaft hole at the connection of the three impellers. The intermediate shaft hole and the fixing sleeve are coaxially arranged and fitted onto the depth-limiting wheel shaft, and fixed by the locking screw.

[0008] In the aforementioned deep-buried drip irrigation pipe laying device, both the trenching end and the laying end of the trench opener are set as "J" shape, with the two "J" shaped structures facing away from each other. The trenching end has a "J" shaped cutting edge, and the trench opener is fixed on the frame by the fixing slot.

[0009] The aforementioned deep-buried drip irrigation pipe laying device includes a drip irrigation pipe delivery pipe and a coil support. The drip irrigation pipe delivery pipe is fixed to the laying end of the furrow opener. The inlet of the drip irrigation pipe delivery pipe is shaped like a flared mouth. The coil support is located directly above the inlet of the drip irrigation pipe delivery pipe and is fixed on the frame. The frame is connected to the power mechanism via a traction suspension.

[0010] The beneficial effects of this utility model are: 1. The laying device of this utility model is equipped with a depth limiting wheel and a depth adjustment device. The laying depth is measured in real time using an ultrasonic rangefinder and the data is transmitted to the controller. The controller controls the extension and retraction length of the electric push rod according to the preset depth requirements to accurately adjust the soil penetration depth of the trencher. At the same time, the electric push rod can also adjust the height of the depth limiting wheel to help ensure the stability of the trenching depth, thereby ensuring the uniformity of the laying depth of the drip irrigation pipe.

[0011] 2. The laying device of this utility model is also equipped with a rotary cutter. During the laying process, the rotary cutter rotates together with the depth limiting wheel to cut up the weeds and roots on the ground, effectively reducing the entanglement of weeds and roots on the trenching operation.

[0012] 3. The trenching end of the trencher adopts a "J"-shaped cutting edge structure, which reduces trenching resistance and improves trenching efficiency. The drip irrigation pipe at the laying end is also a J-shaped hollow pipe with a funnel-shaped inlet to prevent the drip irrigation pipe from being scratched during transportation.

[0013] 4. The device has a reasonable structural design, with close connections and coordination between its various components, and a clear and well-defined working principle. The frame provides stable support for the entire device, allowing each component to operate in an orderly manner. Furthermore, the number of laying units can be arbitrarily increased or decreased according to actual needs, demonstrating strong flexibility and adaptability, and capable of meeting the drip irrigation pipe laying requirements of farmland of different sizes.

Detailed Implementation

[0016] The present invention will be further described below with reference to the embodiments.

[0017] See Figures 1 to 5This utility model discloses a deep-buried drip irrigation pipe laying device, comprising a furrow opener 1, depth-limiting wheels 2, a pipe laying device, a depth adjustment device, a controller 13, and a rotary cutter 9. The furrow opener 1 has a vertically arranged depth adjustment groove 3. Two depth-limiting wheels 2 are respectively fixed at both ends of a depth-limiting wheel axle 4 passing through the depth adjustment groove 3. The depth-limiting wheels are in contact with the ground and roll forward with the laying device, serving to limit the furrow depth. The depth-limiting wheels can ensure the stability of the furrow depth to a certain extent and reduce the shaking of the furrow opener during operation, thus improving the furrowing quality. The depth adjustment device includes an electric push rod 5 and an ultrasonic rangefinder 6. Two electric push rods 5 are provided, one on each side of the furrow opener. The top of each electric push rod 5 is fixed to a fixing slot 7 at the top of the furrow opener 1, and the bottom is movably connected to the depth-limiting wheel axle 4. The extension and retraction of the electric push rod drives the depth-limiting wheel down or up, thereby controlling the furrowing depth. The ultrasonic rangefinder 6 is fixed above the cutting edge of the furrow opener 1 via a ranging bracket 8. The ultrasonic rangefinder uses the principle of ultrasonic wave reflection to measure the distance between the furrow opener and the ground in real time, thereby determining the current laying depth and feeding the measurement data back to the controller. After receiving the signal, the controller controls the extension and retraction of the electric push rod according to the preset depth requirements, precisely adjusting the furrow opener's penetration depth to ensure the uniformity of the drip irrigation pipe laying depth. Simultaneously, the controller can monitor and manage the operation status of the entire device, and can issue an alarm in a timely manner when abnormalities occur. The pipe-laying device is located at the opposite ends of the cutting edge of the furrow opener 1, and the controller is electrically connected to the electric push rod and the ultrasonic rangefinder. Two rotary cutters 9 are provided, fixed on the depth-limiting wheel shaft 4, located on both sides of the trencher. Each rotary cutter 4 is located between the trencher 1 and the electric push rod 5. The rotary cutter 9 includes three sickle-shaped impellers 9-1, a fixing sleeve 9-2, and a locking screw 9-3. The fixing sleeve 9-2 is fixed to one side of the intermediate shaft hole at the connection of the three impellers. The intermediate shaft hole and the fixing sleeve are coaxially arranged and fitted onto the depth-limiting wheel shaft 4. It is fixed by the locking screw 9-3. The impeller contacts the side of the trencher. The depth-limiting wheel shaft can rotate and move up and down along the depth adjustment groove under the action of the electric push rod. Tighten the locking screw to fix the rotary cutter relative to the depth-limiting wheel shaft. The rotary cutter rotates with the depth-limiting wheel to chop weeds and roots, effectively reducing the entanglement of weeds and roots on the trenching operation and improving trenching efficiency.

[0018] See Figure 2 and Figure 5The furrow opener 1 has a "J"-shaped furrowing end and a "J"-shaped cutting edge, which effectively reduces furrowing resistance during the furrowing process. The pipe laying device includes a drip irrigation pipe delivery pipe 10 and a coil support 11. The drip irrigation pipe delivery pipe 10 is J-shaped and fixed to the laying end of the furrow opener. The inlet of the drip irrigation pipe delivery pipe 10 is flared to effectively prevent scratches on the drip irrigation pipe during delivery. The coil support 11 is located directly above the inlet of the drip irrigation pipe delivery pipe 10 and is fixed to the frame 12. The drip irrigation pipe reel is placed on the coil support, and the drip irrigation pipe is released, passes through the drip irrigation pipe delivery pipe, and is laid below the ground as the furrow opener advances. The furrow opener 1 is fixed to the frame 12 through the fixing slot 7. The frame 12 is connected to a power mechanism (such as a tractor) through a traction suspension. Several laying devices of this utility model can be provided and fixed to the frame at intervals.

[0019] The trenching and laying process: The device is connected to a tractor via a traction suspension and moves forward under the tractor's traction. The trench opener breaks through the soil, maintaining a certain depth under the action of the depth-limiting wheel. The drip irrigation pipe is released from the drip irrigation pipe reel, passes through the drip irrigation pipe delivery pipe, and is laid to a stable depth below the ground as the trench opener advances. As the laying device operates, weeds, roots, and film accumulate at the front end of the trench opener. The rotary cutter cuts through the accumulated debris, lifting the trench opener to complete the trenching operation. An ultrasonic rangefinder monitors the laying depth in real time and feeds the data back to the controller (the controller in this invention is a Siemens S7200 PLC). The controller controls the electric push rod to adjust the height of the trench opener based on the feedback data. At the same time, the depth-limiting wheel helps to ensure the stability of the trenching depth. The drip irrigation pipe is laid into the trench during the trenching operation, completing the entire drip irrigation pipe laying process. Through this working principle, the device can effectively solve the problems existing in the current technology and achieve efficient and precise drip irrigation pipe laying operations.
