Be provided with two rectangular-shaped containing cavities of size in the described compression cylinder, wherein big containing cavity and said reinforcement experiment cage are complementary, and little containing cavity is positioned at big containing cavity top, forms sample pressure channel to be tested.
It is rectangular-shaped that described reinforcement experiment cage is grid.
Described test cage loam cake comprises lid, and lid one side is provided with fixed bar, and opposite side is provided with handle, and described fixed bar termination is provided with draw-in groove, and test cage loam cake is covered when the reinforcement experiment cage, and the reinforcement experiment cage links closely.
Described briquetting is provided with fixed bar slot and thermopair backstay, and the fixed bar that covers on described fixed bar slot and the test cage is complementary, and the fixed bar slot inserts reinforcement experiment cage upper end to test cage loam cake along the briquetting bottom after compression.
The present invention simulates goods and is compressed the back situation and carries out the spontaneous heating test of constant temperature, can reduce the specification of in freight transportation process sample packaging more really.Avoid because of test different with transportation stacking degree, the dispute that the influence of dangerous material judgement is caused.The present invention reaches the purpose of the specification of sample packaging in the reduction freight transportation process through the stacking volume that is compressed to appointment, and this device is applicable to as cotton irregular, and the malleable shape is specified the goods of stacking the shape volume.Compared with prior art, beneficial effect of the present invention:
1, compression cylinder has and is compression, separability.Can change the specification of cage according to the regulation of standard.
2, reduce the specification of in freight transportation process sample packaging really, improve the reliability of test.
3, avoid because of test different with transportation stacking degree, the dispute that the influence of dangerous material judgement is caused.
