[0022] Embodiment: As Figures 1 to 4 shown, a sample platform structure of a pellet pressure testing machine. The pellet pressure testing machine includes a base 4, two columns 5 arranged left and right on the base 4, and the two columns 5 are connected by a crossbeam 6. A top pressure device 7 is provided on the crossbeam 6. A top pressure block 71 is provided at the lower end of the top pressure device 7. A round table for placing pellet samples is provided on the base 4, and the top pressure block 71 is vertically aligned with the round table.

[0023] The sample platform structure includes a heightening column 1 and a sample pressing plate 2. An avoidance sinking groove 11 adapted to the round table is provided on the lower end surface of the heightening column 1. The heightening column 1 is arranged on the base 4, and the round table extends into the avoidance sinking groove 11. The sample pressing plate 2 is arranged on the heightening column 1. A pellet sample groove 21 is machined on the upper end surface of the sample pressing plate 2, and the top pressure block 71 is vertically aligned with the sample pressing plate 2.

[0024] When conducting the compressive strength test of pellets, the pellet sample is placed in the pellet sample groove 21. Compared with the round table for placing samples in the existing pellet pressure testing machine, the pellet sample groove 21 can avoid the splashing of pellet samples. The pellet sample is extruded through the cooperation of the top pressure block 71 and the sample pressing plate 2. Since the heightening column 1 raises the test height of the pellet sample, the laboratory technician can conduct the test in a sitting position, increasing the comfort of the laboratory technician's test operation. While the heightening column 1 raises the test height of the pellet sample, it also reduces the test stroke of the top pressure block 71, increasing the test efficiency.

[0025] A sample positioning pit 22 is machined at the center of the bottom surface of the pellet sample groove 21.

[0027] Anti-slip knurling is provided on the gripping section 33.

[0028] Each batch of pellet ore specimens requires 60 iron ore pellets to be analyzed. In the past, it took 90 seconds to analyze each iron ore pellet, and the total analysis time for 60 iron ore pellets was 90 minutes. After improvement, the pellet ore specimen is placed on the positioning pit 22 in the pellet specimen groove 21 for pellet pressure analysis, and the WDW-10 pellet ore pressure testing machine starts to work. It takes 50 seconds to analyze the data of each pellet. After improvement, the problem of splashing of pellet ore specimens is solved, and there is no need to clean the WDW-10 pellet ore pressure testing machine. It greatly saves the inspection time. Each batch of specimens saves 40 minutes of instrument cleaning time. It only takes 50 minutes to analyze 60 iron ore pellets in each batch of specimens. Five batches of pellet ore specimens will save 250 minutes. It greatly improves the test efficiency and meets mass production.
