Description

Automatic point irrigation machine

The utility model relates to a fully automatic point irrigation machine, which belongs to agricultural water conservancy irrigation equipment.

In agricultural production, water conservancy irrigation is extremely important. In the case of perennial drought and drought, if water conservancy irrigation cannot keep up, it will not only affect the growth of plants, but also make the applied granular fertilizer unable to be absorbed by plants because it cannot be dissolved. It has adverse effects on crops and the phenomenon of "root burning". For this, the current solution is to dissolve the fertilizer and apply fertilizer while watering. The equipment used is mostly manual spraying and injection. Irrigation device such as, I also once developed several kinds of manual liquid fertilizer injection devices, and declared patent respectively. However, these manually operated liquid fertilization devices are not suitable for the application of drought-resistant fertilization of large-area crops in rural areas, and the work efficiency is very low. For this reason, I use agricultural machinery as power to develop a fully automatic point irrigation machine, which is installed on a small agricultural four-wheel tractor and dragged, and one person operates the agricultural four-wheel vehicle to realize large-scale water injection irrigation. .
