The output shaft end of the servo motor 73 is fixedly connected to the rear end of the drive shaft 72. The punching block 5 is used to pressurize the concrete to complete the test. Then the servo motor 73 controls the rotation of the drive shaft 72. The rotation of the drive shaft 72 drives the rotating shaft 71 to rotate through the synchronous belt assembly. The rotating shaft 71 drives the flip block 7 to rotate 180 degrees, so that the debris rotates 180 degrees and falls onto the guide plate 4 to complete the removal.

[0031] See also Figure 4As shown, the clamping assembly includes a clamping block 8, a compression spring I81, a slide bar 82, a buffer spring 83 and a trigger assembly. Four clamping blocks 8 are slidably connected at uniform intervals along the circumferential direction on the flip block 7. When the clamping block 8 moves inward and contacts the concrete, the clamping block 8 can clamp and fix the concrete. A compression spring I81 is connected between the inner side surfaces of the four clamping blocks 8 and the inner side of the flip block 7. The bottom ends of the four clamping blocks 8 are embedded and slidably connected with a slide bar 82. The top ends of the four slide bars 82 are respectively connected to the inner sides of the four clamping blocks 8 with buffer springs 83. A trigger assembly is provided on the flip block 7. When the trigger assembly is operated, the trigger assembly can drive the slide bar 82 to move inward; the trigger assembly includes a swing plate 84 and a circular trigger plate 85. , contact rod 86 and reset spring I87, four swing plates 84 are connected to the bottom of the flip block 7 in a circumferentially uniformly spaced rotation manner, and a straight hole is opened on the outer side of the four swing plates 84, and a circular trigger plate 85 is slidably connected between the four swing plates 84. The inner side of the circular trigger plate 85 is conical, and the inner side of the circular trigger plate 85 contacts the bottom ends of the four slide bars 82. When the circular trigger plate 85 moves upward, the circular trigger plate 85 can drive the slide bars 82 to move inward. A contact rod 86 is slidably connected to the middle part of the flip block 7. When the contact rod 86 moves downward and contacts the inner end of the swing plate 84, the contact rod 86 can drive the swing plate 84 to swing, and a reset spring I87 is connected between the lower part of the contact rod 86 and the bottom of the flip block 7.

[0032] First, pull the box door 2 forward and swing it open, and then place the formed concrete on the contact rod 86. Due to the effect of gravity, the concrete drives the contact rod 86 to move downward, the return spring I87 is stretched, the contact rod 86 moves downward and contacts the inner end of the swing plate 84, the contact rod 86 drives the inner end of the swing plate 84 to swing downward, the inner end of the swing plate 84 swings downward so that the outer end swings upward, the outer end of the swing plate 84 swings upward and drives the circular trigger plate 85 to move upward, the circular trigger plate 85 moves upward and drives the slide bar 82 to move inward, the slide bar 82 moves inward and drives the clamping block 8 to move inward, the compression spring I81 is compressed, the clamping block 8 moves inward and contacts the concrete, the clamping block 8 clamps the concrete and fixes it, and the clamping block 8 stops. The clamping block 8 stops the slide bar 82 from moving inward, and the circular trigger plate 85 continues to move upward to drive the slide bar 82 to move upward. The buffer spring 83 is compressed, and then when the concrete contacts the flip block 7, the concrete stops moving downward, and then the box door 2 is pulled back to swing and close, and then the telescopic rod of the hydraulic cylinder 6 is shortened to drive the punching block 5 to move downward. When the punching block 5 moves downward and contacts the concrete, the punching block 5 applies pressure to the concrete, which tests the compressive strength of the concrete. When the concrete is crushed, the punching block 5 completes the pressure test on the concrete, and the punching block 5 transmits the test data to the terminal. Since the concrete is crushed, the concrete stops limiting the contact rod 86. Due to the action of the reset spring Ⅰ87, the contact rod 86 moves upward to reset and disengages from the inner end of the swing plate 84. The swing plate 84 swings and resets, driving the circular trigger plate 85 to move downward to reset. The circular trigger plate 85 resets and stops to limit the slide bar 82. Due to the action of the buffer spring 83, the slide bar 82 moves downward to reset, and due to the action of the compression spring Ⅰ81, the clamping block 8 moves outward to reset and drives the slide bar 82 to move outward to reset. Then, the telescopic rod of the hydraulic cylinder 6 is started to extend and drive the stamping block 5 to move upward to reset. Then, the servo motor 73 is started to drive the drive shaft 72 to rotate 180 degrees. The drive shaft 72 rotates 180 degrees through the synchronous belt assembly to drive the rotating shaft 71 to rotate 180 degrees. The rotating shaft 71 rotates one The slag is rotated 180 degrees and the slag is rotated 180 degrees, and the slag is rotated 180 degrees and the slag is rotated 180 degrees. During the rotation of the slag, the annular baffle 3 can block the slag to prevent the slag from falling into the box body 1. The slag rotates 180 degrees and falls from the flip block 7 to the guide plate 4. Since the guide plate 4 is inclined, the slag on the guide plate 4 falls and is collected. In this way, there is no need for manual removal of the slag, thereby improving the efficiency of subsequent tests. When all the slag on the flip block 7 falls off, the servo motor 73 is started again to drive the drive shaft 72 to rotate 180 degrees, which makes the flip block 7 rotate 180 degrees to reset. According to the above operation, the concrete can be pressure tested again.

[0034] See also Figure 7 and Figure 8 As shown, it also includes a support component installed between the frame 21 and the guide plate 4, the support component includes a support frame 10, a wire tube 101, a pull wire 102 and a pushing component, the support frame 10 is slidably connected between the bottom of the frame 21 and the guide plate 4, when the support frame 10 moves upward and contacts the flip block 7, the support frame 10 can support and limit the flip block 7, the four top ends of the support frame 10 are all L-shaped, and can fit tightly with the bottom edge of the flip block 7, the left and right sides of the frame 21 are respectively symmetrically fixed with wire tubes 101 between the left and right sides of the box body 1, the left and right sides of the support frame 10 are symmetrically fixed with pull wires 102, the tail ends of the four pull wires 102 pass through the four wire tubes 101, and the stamping block 5 A pushing component is arranged between the box body 1. When the pushing component is in operation, the pushing component can drive the pull wire 102 to move; the pushing component includes a movable rod 103, a horizontal plate 104 and a compression spring III 105.

The left and right sides of the horizontal plate 104 are respectively fixedly connected with the movable rods 103 on the left and right sides. Compression springs III 105 are connected between the left and right sides of the top of the horizontal plate 104 and the upper parts of the left and right sides of the stamping block 5.

[0035] Initially, the reset spring II 92 is in a stretched state. When the punch block 5 moves downward to perform a pressure test on the concrete, the punch block 5 moves downward to drive the driving plate 96 to move downward. The driving plate 96 moves downward to stop limiting the L-shaped rod 95. Due to the action of the reset spring II 92, the guide rod 9 moves downward to drive the guide frame 91 to move downward. The guide frame 91 moves downward to drive the brush 93 to move downward. The brush 93 moves downward synchronously with the punch block 5. At the same time, the brush 93 moves downward to drive the contact roller 94 to move downward. The contact roller 94 moves downward and slides on the trigger frame 98. The trigger frame 98 drives the contact roller 94 to move forward. The contact roller 94 moves forward to drive the brush 93 to move forward. The compression spring II 97 is compressed, and the brush 93 moves forward to contact the bottom of the punch block 5. As the contact roller 94 continues to move downward, the contact roller 94 stops being limited by the trigger frame 98. Due to the action of the compression spring II 97, the brush 93 moves backward to reset and drives the contact roller 94 to move backward to reset. The punching block 5 continues to drive the driving plate 96 to move downward, and the driving plate 96 is out of contact with the L-shaped rod 95. When the punching block 5 completes the pressure test on the concrete, the punching block 5 moves upward and resets, driving the driving plate 96 to move upward, and the driving plate 96 moves upward and contacts with the L-shaped rod 95. The driving plate 96 drives the L-shaped rod 95 to move upward and reset, and the L-shaped rod 95 drives the guide frame 91 to move upward, and the guide frame 91 drives the guide rod 9 to move upward and reset, and the reset spring II 92 is stretched, and the guide frame 91 moves upward and drives the brush 93 to move upward, and the brush 93 drives the contact roller 94 to move upward, and the contact roller 94 moves upward and contacts with the inclined surface of the trigger frame 98 again, and the trigger frame 98 drives the contact roller 94 to move forward, which also makes the brush 93 move forward and contact with the bottom of the punching block 5, and the brush 93 removes the debris attached to the bottom of the punching block 5, and as the contact roller 94 continues to move upward and reset, the contact roller 94 is not limited by the trigger frame 98, and the brush 93 drives the contact roller 94 to move backward and reset. In this way, it is possible to prevent debris from being attached to the bottom of the punching block 5 and affecting subsequent use, thereby ensuring the use effect of the punching block 5.

[0036] When the punching block 5 moves downward, the punching block 5 drives the cross plate 104 to move downward through the compression spring III 105, and the cross plate 104 moves downward to drive the movable rod 103 to move downward, and the movable rod 103 moves downward to drive the pull wire 102 to move downward, and the pull wire 102 moves downward and drives the support frame 10 to move upward through the wire tube 101, and the support frame 10 moves upward and contacts the flip block 7. Since the top of the support frame 10 is L-shaped, it can fit tightly with the bottom of the flip block 7 for support, and the support frame 10 stops moving upward. The support frame 10 stops moving downward through the pull wire 102 to stop the movable rod 103 from moving downward, and the movable rod 103 stops moving downward on the cross plate 104, and then the punching block 5 continues to move downward to compress the compression spring III 105, and pressurize the concrete to complete the pressure test on the concrete. When the punching block 5 moves upward and resets, the punching block 5 first resets the compression spring III 105, and then the punching block 5 drives the horizontal plate 104 to move upward through the compression spring III 105, and the horizontal plate 104 moves upward and drives the movable rod 103 to move upward and reset, and the movable rod 103 resets and drives the pull wire 102 to move upward, and the pull wire 102 is loosened. Due to the effect of gravity, the support frame 10 moves downward and resets and disengages from the flip block 7. In this way, the flip block 7 can be prevented from rotating to affect the pressure test of the concrete, thereby improving the stability of the pressure test.

[0037] See also Fig. 9 As shown, it also includes a driving wheel 11, an n-shaped rod 12 and a return spring III 13. The return spring III 13 is symmetrically connected between the bottom rear side of the guide plate 4 and the bottom rear side of the frame 21. The n-shaped rod 12 is fixedly connected to the top rear side of the guide plate 4. The driving wheel 11 is fixedly sleeved on the front side of the driving shaft 72. The driving wheel 11 is in contact with the inner side of the n-shaped rod 12. When the driving wheel 11 rotates, the driving wheel 11 can drive the n-shaped rod 12 to move upward.

[0038] See also Fig. 9 As shown, an observation window 14 is also included, and the box body 1 is fixedly connected with the observation window 14.

[0039] When the servo motor 73 starts to drive the drive shaft 72 to rotate, the drive shaft 72 also drives the drive wheel 11 to rotate. When the convex end of the drive wheel 11 contacts the n-shaped rod 12, the drive wheel 11 drives the n-shaped rod 12 to move upward. The n-shaped rod 12 moves upward to drive the guide plate 4 to move upward, and the reset spring III 13 is stretched. As the drive wheel 11 continues to rotate, the convex end of the drive wheel 11 is out of contact with the n-shaped rod 12. Due to the action of the reset spring III 13, the guide plate 4 moves downward to drive the n-shaped rod 12 to move downward and reset. This is repeated, so that the guide plate 4 can continuously move up and down. When the slag falls onto the guide plate 4, the guide plate 4 moves up and down to shake the slag. When the servo motor 73 is turned off, the servo motor 73 stops driving the drive shaft 72 to rotate, the drive shaft 72 stops driving the drive wheel 11 to rotate, and the guide plate 4 stops moving up and down. In this way, it can prevent the slag from being difficult to fall and collect on the guide plate 4, so that the slag on the guide plate 4 can be better collected.

[0040] When the punching block 5 performs a pressure test on the concrete, the operator can view the pressure test of the concrete through the observation window 14. In this way, corresponding processing can be made in time according to the situation of the concrete pressure test.
