Flexible type in-situ speed reducing root system tension testing device

Abstract

The invention discloses a flexible type in-situ speed reducing root system tension testing device which comprises a screw rod machine fixing plate, a screw rod tensile machine, a control device and aflexible connection clamping head, wherein the screw rod tensile machine, the control device and the flexible connection clamping head are arranged on the screw rod machine fixing plate, a through hole and an installation hole which penetrate through the screw rod machine fixing plate are arranged on the screw rod machine fixing plate, the screw rod tensile machine is arranged on the screw rod machine fixing plate through the installation hole, and a displacement rod of the screw rod tensile machine penetrates through the through hole to extend to the front end of the screw rod machine fixingplate. When a tension sensor at the front end of the device, cannot sense tension, the control device can correspondingly control the screw rod tensile machine to stop working, and the corresponding displacement distance of the displacement rod is recorded; thus, limit data of tensile capable of bearing by a root system can be obtained, the data are mutually proved from two sides, and data resultsare more accurate; furthermore, the whole device has the advantages of reasonable structure, clear principle, convenience in use and ability in effectively testing root system tensile data.

Description

technical field [0001] The invention relates to a root tension measuring device, in particular to a flexible in-situ deceleration root tension measuring device. Background technique [0002] The existing plant tensile force measuring device usually only measures some plants with relatively small anchoring force, and the structure of the existing measuring device is usually set to the type of triangular support structure, and the measuring direction is set to fix the whole plant from top to bottom. The root tension is measured after the plant is pulled up, but it is not easy to measure the root tension for some large rooted plants; and even if there is an existing in-situ deceleration root tension measurement device, it is necessary to use a connecting device such as a clamp to connect all the roots. The root system is clamped for measurement. Most of the connection fixtures in the existing devices are directly fixed by the fixture. This kind of rigid connection fixture is ea...

Problems solved by technology

[0002] Existing plant tension measurement devices usually only measure plants with small anchoring forces, and the structure of existing measurement devices is usually set as a triangular bracket structure, and the measurement direction is set to fix the whole plant from top to bottom. After the plant is pulled up, the pulling force of the root system is measured, but it is not easy to measure the pulling force of the root system for some large root plants; Measure the clamping of the root system. Most of the connecting fixtures in the existing devices are directly fixed by the fixture. The fixture of this rigid connection method is easy to destroy the integrity of the root system when it is fixed, and weaken its tensile capacity. The tensile force of the entire root system cannot be measured correctly. Usually, it is directly broken from the fixed point when the root system has not really reached the limit of the tensile force, which affects the measurement results.
