Description

Technical Field

[0001] The utility model relates to the technical field of processing pipe belts for farmland irrigation, in particular to an automatic punching device for a main pipe belt for farmland irrigation. Background Art

[0002] PE hose, as the main water supply conduit for patch-type drip irrigation pipes, is an essential component of today's high-standard farmland layout. During the crop sowing process on high-standard farmland, the planting and sowing distance of crops is fixed by mechanical equipment. Existing drilling methods rely on manual drilling with electric drills or manual hole openers, resulting in non-standard hole spacing. Excessive hole spacing can lead to a mismatch between the holes and the crops, resulting in differences in the amount of water received by the crops. Manual hole drilling also significantly increases work time, making human resources extremely valuable during spring plowing. Furthermore, with the increasing production speed of PE hose, the servo motor and drill bit cannot maintain the high drilling frequency required for single-motor drilling when the hole spacing is less than 400 mm and the production speed is greater than 15 meters per minute. This utility model is proposed based on this research background and aims to provide an automatic hole-punching device for farmland irrigation main pipes to meet practical design and usage requirements.

[0012] The automatic punching device for farmland irrigation main pipes of the utility model has the following beneficial effects:

[0013] (1) By pre-punching the PE water hose produced online, the workload and working time of the pipe connection process are reduced, thereby greatly improving the work efficiency of the staff. In addition, it can greatly improve the efficiency of arranging waterways in high-standard farmland and improve the accuracy of hole drilling in the entire pipe production process.

[0014] (2) By adjusting the distance and size of the holes, the problem of incorrect holes and multiple holes in the pipe can be effectively solved, which can meet the use needs of the main pipe for farmland irrigation of most crops, and also reduce the waste of water resources to a certain extent, and reduce the overall production operation cost.
