Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to an automatic laying device for irrigation pipes. Background Art

[0002] my country's agricultural production model is undergoing significant changes, and the corresponding agricultural water-saving irrigation control technology is still immature. Currently, the main irrigation methods used are as follows: surface irrigation, which uses surface irrigation ditches, furrows, or grid fields for irrigation. Surface irrigation is the oldest and most common irrigation method, requiring minimal equipment. Sprinkler irrigation uses specialized equipment such as sprinklers to spray pressurized water into the air, causing droplets to fall onto the surface of the irrigation area and crops. Underground irrigation, which involves burying pipes in the soil, allows water to seep out of the pipes to moisten the soil and provide water for irrigation. It is an ideal water-saving irrigation method, but it has high construction costs and requires manual trenching and burying of drip irrigation pipes, which is labor-intensive. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-Figure 5 As shown, an automatic irrigation pipe laying device includes a handrail frame 5, two support arms 1 are symmetrically fixed to one end of the handrail frame 5, a movable wheel 2 is rotatably mounted on the lower end of each support arm 1, and the two support arms 1 are fixed together by a fixed shaft 3. The upper end of the support arm 1 is detachably connected to a pipe reel 7 with an irrigation pipe wound thereon, and at least one pipe burying device 4 is slidably mounted on the pipe reel 7. When multiple pipe burying devices 4 are provided, multiple irrigation pipes can be buried simultaneously.

[0026] The pipe burying device 4 includes a hollow delivery pipe 401. The inner cavity size of the delivery pipe 401 is larger than that of the irrigation pipe, which is convenient for the irrigation pipe to pass through the delivery pipe 401. A connecting arm 402 is fixed to one side of the upper end of the delivery pipe 401. The end of the connecting arm 402 is fixed with a sliding sleeve 407 slidably mounted on the fixed shaft 3. The side wall of the sliding sleeve 407 is threaded with a screw that fixes the sliding sleeve 407 to the fixed shaft 3. The position of the pipe burying device 4 can be adjusted by loosening the screw, which is convenient for adjusting the buried pipe position according to needs. A furrow opener 406 is fixed to the lower end of the delivery pipe 401. A trench can be dug on the ground to facilitate pipe burial. The trench opener 406 and the connecting arm 402 are located on the same side of the conveying pipe 401. A fixed arm 408 is fixed to the side of the conveying pipe 401 away from the connecting arm 402. A height-adjustable guide rod 410 is fixed to the fixed arm 408. A portal frame 409 is fixed to the lower end of the guide rod 410. A rolling wheel 411 is rotatably installed at the lower end of the portal frame 409. The rolling wheel 411 coincides with the center line of the trench opener 406. The diameter of the rolling wheel 411 does not exceed the diameter of the moving wheel 2. The rolling wheel 411 can be used to press the irrigation pipe into the trench dug by the trench opener 406.

[0027] In this embodiment, at least one fixed slot 6 for mounting a pipe roller 7 is formed at the upper end of the support arm 1. Both ends of the pipe roller 7 are clamped in the fixed slot 6, which facilitates the installation of the pipe roller 7. The multiple fixed slots 6 facilitate the adjustment of the installation position of the pipe roller 7. When the length of the pipe wound on the pipe roller 7 is long, the pipe roller 7 is installed high. When the pipe wound on the pipe roller 7 is short, the installation position of the pipe roller 7 can be lowered.

[0028] In this embodiment, a rear opening 404 is provided on the side of the lower end of the delivery pipe 401 away from the drain 406, and the edges of the upper end of the delivery pipe 401 and the rear opening 404 at the lower end of the delivery pipe 401 are rounded to prevent wear and damage during irrigation pipe transportation.

[0029] In this embodiment, an upper guide wheel 403 is fixed at the upper end of the conveying pipe 401 near the pipe mouth, and a lower guide wheel 405 is fixed at the lower end of the conveying pipe 401 near the rear opening 404. Both the upper guide wheel 403 and the lower guide wheel 405 are pulleys with a groove in the center, which can reduce friction and reduce wear on the pipeline.

[0030] In this embodiment, a guide ring 415 is fixed on the upper surface of the connecting arm 402 near the upper guide wheel 403 to guide the position of the pipe and ensure that the irrigation pipe does not fall off the wheel when it contacts the upper guide wheel 403.

[0031] In this embodiment, the guide rod 410 passes through the fixed arm 408. The guide rod 410 is a threaded rod. A limiting nut is installed on the shaft section of the guide rod 410 above the fixed arm 408. A compression spring is nested on the shaft section of the guide rod 410 below the fixed arm 408. The two ends of the compression spring are respectively against the fixed arm 408 and the door frame 409. The height of the rolling wheel 411 can be adjusted by adjusting the position of the limiting nut.

[0032] In this embodiment, two mounting plates 412 are symmetrically fixed on both sides of the portal frame 409. A plurality of adjustment holes 413 are formed on the mounting plates 412. A covering device 414 is fixed to the lower end of each mounting plate 412 by bolts. The two covering devices 414 are arranged in an "eight" shape. The covering device 411 can be used to cover the soil turned over by the furrow opener 406 back onto the irrigation pipe to complete the covering of the irrigation pipe.

[0033] As a preferred solution, an electric drive mechanism connected to the moving wheel 2 is fixed on the side wall of the lower end of the support arm 1. The electric drive device is used for movement, which saves more effort when laying pipelines.

[0034] As another preferred solution, the armrest frame 5 can be replaced by a traction frame, and the traction frame is used to fix the device on a traction machine such as a tractor, so as to facilitate large-scale use.

[0035] The working principle of the present invention is as follows: when in use, a sowing or fertilizing mechanism can be attached to the fixed shaft 3, which is parallel to the pipe burying device 4, and the sowing or fertilizing operation is completed while the pipe is buried. The pipe reel 7 with the irrigation pipe coiled around it is placed on the upper end of the support arm 1, and the end of the pipe passes through the guide ring 415 and the conveying pipe 401 in turn, and then passes through the rear opening 404 and is pressed under the rolling wheel 411. When the pipe is buried, when walking in the field with the handrail 5, the handrail 5 is pressed downward so that the furrow opener 406 is inserted into the soil to open a trench underground. At the same time, the irrigation pipe is synchronously laid in the trench under the rolling of the rolling wheel 411, and then the soil covering device 414 scrapes the soil on both sides of the trench into the trench to cover the irrigation pipe, thereby completing the automatic laying of the irrigation pipe.

[0036] Components not described in detail herein are prior art.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
