Apparatus used for measuring plant root system pullout force and method thereof

Abstract

An apparatus used for measuring a plant root system pullout force and a method thereof are disclosed and belong to the plant root system pulling force measurement technology field. The apparatus used for measuring the plant root system pullout force comprises a main frame, an assistant support, a swing arm, a clamping component, an air cylinder, an air pump, an air pressure sensor and a controller. One end of the main frame is provided with a first opening and one end of the main frame is movably installed on the assistant support. The swing arm is provided with multiple pairs of first shaft holes. The multiple pairs of first shaft holes are distributed at intervals along a length direction of the swing arm. A rotating shaft passes through one pair of first shaft holes on the swing arm and one pair of second shaft holes on the main frame so that the swing arm is installed in the main frame. The clamping component is installed on one end of the swing arm and the clamping component is provided with a second opening. The air cylinder is installed on the main frame. A piston rod of the air cylinder passes through the main frame and is connected to the other end of the swing arm. The air pump is installed on the main frame and is connected to the air cylinder through a gas guide tube. The air pressure sensor is connected to the air cylinder. The air pump and the air pressure sensor are connected to the controller.

Description

technical field [0001] The invention relates to the technical field of plant root system tension measurement, in particular to a device and method for measuring plant root pull-out force. Background technique [0002] The pull-out force of plant roots is an important basis for judging the soil-fixing ability of plants and the growth of plant roots. The measurement of pull-out force of plant roots is also a common scientific research method for studying plants and soil and water conservation projects. There are various methods and equipment for measuring the pull-out force of plant roots, but most of them are complete sets of equipment formed by combining different types of equipment under existing conditions. The operation is relatively complicated, and targeted special automatic measurement equipment is still rare. [0003] At present, there are some devices called plant root pull-out force testers on the market, but many of them are suitable for the measurement of the tens...

AI Technical Summary

Problems solved by technology

At present, many test instruments of this type are composed of multiple parts and are of split design. This type of equipment needs to carry multiple parts when measuring in the field, and it needs to be assembled on site during the measurement, and the operation and movement are very complicated.
