Abstract

The invention discloses a rubber tree bark tensile strength testing device and a testing method. The rubber tree bark tensile strength testing device comprises a first clamping head, a second clamping head, a linear sliding rail, a hoop, a tension detector and a telescopic rod, wherein the linear sliding rail is fixed to a rubber tree through the hoop, the first clamping head and the second clamping head are both in sliding connection with the linear sliding rail, one end of the telescopic rod is fixedly connected with the first clamping head, the other end of the telescopic rod is provided with the tension detector, and the other end of the tension detector is connected with the second clamping head. The rubber tree bark tensile strength testing device provided by the invention can be used for carrying out a tensile strength test on a rubber tree, so the influence on the rubber tree is reduced.

Description

technical field [0001] The invention relates to the technical field of tensile strength testing, in particular to a rubber bark tensile strength testing device. Background technique [0002] At present, in testing the tensile properties and shear strength of rubber tree bark, it is necessary to test the mechanical parameters of the fresh bark of rubber tree. Width 3-5cm, use a cutting knife to cut two parallel cuts along the trunk direction, and then cut two cuts along the circumference of the trunk, use tools to remove the bark, immediately wrap it with a damp cloth and put it in a refrigerator to keep moisture , and finally brought to the laboratory for tensile strength testing using a tensile strength testing machine. Existing tensile strength testing devices are bulky and costly. For example, a non-vibrating material tensile testing machine with a publication number of CN112229725A cannot be transported to the rubber forest for testing. The rubber bark needs to be cut f...
