When the clamping plates 403 slide and separate from the baffle plate 401, the clamping plates 403 can be displaced to contact the side wall of the concrete test block.
[0027] As a technical optimization solution of the utility model, the protective mechanism 3 includes a protective cover 301 and a transparent plate 302. The protective cover 301 is rotatably connected to the body 2, and a support plate 304 is fixedly installed on the protective cover 301.

Through the transparent plate 302, the operator can easily check the status of the test block during the detection process.
[0028] As a technical optimization solution of the utility model, the width of the transparent plate 302 is equal to the width of the through groove 303, and the height of the protective cover 301 is greater than the height of the baffle 401. The setting of the protective cover 301 can prevent the fragments generated when the test block is crushed from flying out and injuring the operator.
[0029] As a technical optimization solution of the utility model, the guide plate 402 is arranged in an inclined structure, and the guide plate 402 is located at one end of the base 404 close to the protective cover 301. Through the guide plate 402, the operator can easily clean out the debris inside the base 404.
[0030] As a technical optimization solution of the present utility model, the control mechanism 1 includes a control cabinet 101 and a digital display instrument 102. The control cabinet 101 is fixedly installed on the side wall of the body 2. The digital display instrument 102, an oil supply valve 103 and an oil return valve 104 are fixedly installed on the control cabinet 101.

[0031] As a technical optimization solution of the utility model, the two ends of the abutment plate 304 are arranged in an inclined structure, and the end of the protective cover 301 facing away from the control cabinet 101 is arranged in an arc structure. The abutment plate 304 abuts against the end of the guide plate 402, which can prevent fragments from falling out of the base 404 during the detection process.
[0032] As a technical optimization solution of the utility model, the resistance mechanism 6 includes a fixed block 602, the fixed block 602 is fixedly installed on the body 2, the fixed block 602 is threadedly connected with a screw 603, the screw 603 is fixedly connected with a handwheel 601 and an upper pressure plate 604, and the upper pressure plate 604 squeezes the top of the concrete test block to facilitate its detection.
[0033] As a technical optimization solution of the utility model, the upper pressure plate 604 is located at the end of the screw 603 close to the lower pressure plate 405, and the width of the upper pressure plate 604 is equal to the width of the lower pressure plate 405. The test block is located in the center of the lower pressure plate 405, which makes it easier for the upper pressure plate 604 to squeeze it.
[0034] As a technical optimization solution of the utility model, the fixed block 602 is located at the top of the body 2, and the hand wheel 601 is located at one end of the screw 603 close to the fixed block 602. When the screw 603 is started, it can easily drive the upper pressure plate 604 to move.
[0035] When the utility model is in use, the power is turned on, the motor is started, the return oil valve 104 is closed, the speed valve handle is unscrewed in the counterclockwise direction to supply oil so that the piston rises from the bottom of the cylinder. When the machine body 2 is in an open state, the operator can put the concrete test block into the top of the lower pressure plate 405 fixed on the base 404, and then turn on the control switch of the hydraulic rod 406. The two hydraulic rods 406 are simultaneously started inside the baffle 401 and drive the clamping plate 403 fixed at the telescopic end to slide. The clamping plate 403 slides out from the inside of the baffle 401 and moves toward the direction close to the concrete test block. When the two clamping plates 403 both hit the side wall of the test block, the position of the test block can be adjusted, so as to facilitate the concrete test block to be in the center of the lower pressure plate 405, which is conducive to preventing the situation that the manual adjustment of the test block position is easy to deviate and cause errors in the detection result; turning the hand wheel 601 can drive the lead screw 603 to rotate in the fixed block 602, and the lead screw 603 drives the upper pressure plate 604 fixed at the end to move toward the top of the concrete test block. When there is a 1mm to 2mm gap between the test block and the upper pressure plate 604, the distance between the upper pressure plate 604 and the concrete test block can be adjusted easily. After the test block is placed, the operator can rotate the protective cover 301, thereby driving the abutment plate 304 fixed to the side wall to rotate. When the end of the protective cover 301 away from the control cabinet 101 is engaged with the machine body 2, the abutment plate 304 can be abutted against the end of the guide plate 402, thereby facilitating the sealing of the abutment plate 304, which is beneficial to prevent the broken test block from falling out of the bottom during the detection process. The seat 404; the transparent plate 302 is installed at the through slot 303 provided on the abutment plate 304. During the test, the operator can check the state of the test block through the transparent plate 302; according to the digital display instrument 102 on the control cabinet 101, the operator can adjust the size of the oil delivery valve 103. When the test block has not yet contacted the upper pressure plate 604, the adjustable speed valve can rise quickly. When the test block contacts the upper pressure plate 604, the speed valve can be appropriately adjusted according to the loading speed to load until the test block is crushed. After the test block is crushed, open the return oil valve 104 to make the piston fall back, remove the broken test block, and the removed broken blocks can be recovered through the guide plate 402 set on an inclined surface; close the return oil valve 104 and do the next test.
