In multiple comparative tests, counterweights 15 of different weights are placed above the bearing plate 14 to simulate different pressures applied by the user to the pneumatic pick, and then the pneumatic pick is started for testing, so as to simulate the working conditions of the pneumatic pick under different pressures and the amplitude of the pneumatic pick jumping due to back vibration under different pressures, and the detection results are relatively close to the actual use conditions.

[0024] As Figures 1 to 4As shown, a slag discharge port 2 is opened at the bottom of the placement groove 12; a pair of partition plates 21 are symmetrically and rotatably connected in the middle of the slag discharge port 2; a pair of limiting rods 22 are slidably connected in the middle of the detection frame 1; the pair of limiting rods 22 are respectively located below the pair of partition plates 21; a collection box 23 is slidably connected in the middle of the detection frame 1; the collection box 23 is located below the slag discharge port 2; a plurality of rotating rollers 24 are rotatably connected to the inner bottom of the detection frame 1; the collection box 23 is arranged above the plurality of rotating rollers 24; during operation, when testing the pneumatic pick tool, the pneumatic pick will break the concrete test block placed in the placement groove 12. After the test is completed, the larger concrete fragments can be taken out, and then the pair of limiting rods 22 are slid to turn the pair of partition plates 21 downward to open the slag discharge port 2, and then the smaller residues and dust remaining in the placement groove 12 can be conveniently dialed into the slag discharge port 2 and slide into the collection box 23. Through the above structure, after a period of detection, the concrete residues remaining in the placement groove 12 can be conveniently collected and cleaned, improving the convenience of use of the device.

[0025] As Figures 1 to 3 shown, clamping screws 3 are threadedly connected to the opposite side walls of the placement groove 12; a regulating arm 31 is fixedly connected to the end of the clamping screw 3 away from the placement groove 12; during operation, after placing the concrete block for testing in the placement groove 12, rotate the regulating arm 31 to drive the clamping screw 3 to move, so that the pair of clamping screws 3 clamp the concrete block, thereby reducing the influence of the movement of the concrete block on the test result when detecting the pneumatic pick.

[0026] As Figures 1 to 3 shown, two groups of elastic ropes 4 are symmetrically and fixedly connected to the opposite side walls of the placement groove 12; a scraping plate 41 is fixedly connected to the end of the elastic rope 4; the scraping plate 41 is arranged in contact with the end of the clamping screw 3; during operation, when clamping the concrete block, the pair of scraping plates 41 will increase the contact area between the clamping screw 3 and the block, thereby improving the clamping effect, and after the test is completed, the pair of scraping plates 41 can be scraped along the bottom surface of the placement groove 12 to scrape the residues and dust into the slag discharge port 2, improving the cleaning speed.

[0030] During operation, place the concrete block for testing in the placement groove 12, then connect the pneumatic pick tool to be tested to the bottom end of the connecting rod 13 so that the output end of the pneumatic pick falls on the top of the concrete block. In multiple comparative tests, place counterweights 15 of different weights above the bearing plate 14 to simulate different pressures applied by the user to the pneumatic pick, and then start the pneumatic pick for testing.
