Deep potato irrigation device

Abstract

The invention discloses a deep irrigation device for potatoes, which comprises a machine frame and a screw-in rod. A spiral plate is arranged on the surface of the screw-in rod. One end of the screw-in rod is connected with a first screw, which is threaded on On the frame, the screw rod and the first screw rod are both hollow and communicated with each other, and the screw rod is provided with a first through hole; the first screw rod is connected with a biaxial stepping motor, and above the biaxial stepping motor is provided Cylinder, the other output shaft of the biaxial stepping motor is connected with a second screw rod, the second screw rod rotates and slides in the cylinder, and a piston plate is slid in the cylinder, the second screw rod passes through the piston plate and connects with the piston plate Threaded connection, the first screw rod is provided with a second through hole communicating with the hollow, the second through hole is rotatably provided with a hollow disc, and an infusion tube is communicated between the cylinder and the disc. The invention can reduce the damage to the root system of the potato plant, has the advantages of convenient and simple fertilization, low labor intensity, and can perform deep and precise fertilization on the root system of the plant.

Description

technical field [0001] The invention relates to the technical field, in particular to a deep irrigation device for potatoes. Background technique [0002] For now, the existing fertilization and irrigation devices are mainly aimed at plowing the field and then fertilizing and irrigating by watering. This traditional fertilizing and irrigating method is only suitable for common crops that grow in large areas and have shallow root systems. For plants with deep root systems such as potatoes, traditional fertilization devices are not suitable for irrigation. [0003] At present, when irrigating and fertilizing plants with deep root systems, it is generally only possible to artificially open ditches and bury them deeply. However, this traditional fertilization and irrigation method has the following problems: 1. This method of fertilization needs to be applied around the plants at first. Dig deeper irrigation pits, but this will cause greater damage to the roots of plants such a...

Problems solved by technology

[0003] At present, when irrigating and fertilizing plants with deep root systems, it is generally only possible to artificially open ditches and bury them deeply. However, this traditional fertilization and irrigation method has the following problems: 1. This method of fertilization needs to be applied around the plants at first. Dig deeper irrigation pits, but this will cause greater damage to the roots of plants such as potatoes, thereby affecting the growth of potato plants; 2. Such fertilization irrigation needs to dig pits first, then irrigate, and finally landfill This is more troublesome and inconvenient, the labor intensity is high, and the position of deep fertilization is not accurate
