[0002] The base material of the lithifier is made of a mixture of lithifier and crushed soil, gravel, coal gangue, construction waste and other solid wastes.

[0014] The present invention provides a compressive performance testing device and a testing method for lithogenic agent base materials through improvements. Compared with the prior art, the present invention has the following improvements and advantages: First, because there is a gap between the slide plate and the impact plate, the subsequent slide plate has a distance to accelerate, and thus can impact the material. When the movable frame initially contracts, the gas drawn in by the air pump passes through the setting of the connecting mechanism, so that the impact plate can perform impact testing on the material during the contraction process of the movable frame. There is no need to wait until the movable frame is completely contracted before performing the impact test, thereby saving the overall time of the two tests and improving the test efficiency. In addition, the impact plate can move back and forth to impact the material, and the impact force of the impact plate on the material gradually increases. It is possible to use a variety of impact forces to perform impact testing on the material, thereby improving the test effect. Second, when the moving frame moves toward the material and the gear rotates, the shift block will squeeze the rotating plate into the rotating ring. When the moving frame moves away from the material, the shift block will drive the rotating plate and the rotating ring to rotate and perform the impact test. This setting is to enable the device to perform a static pressure test on the material first, and then perform an impact test, to prevent the impact force from being greater than the static pressure, causing damage to the material after the impact test, and then making it impossible to perform the subsequent static pressure test, thereby ensuring the rationality of the test; Third: When the mobile rack moves to the point where the connecting slot coincides with the straight slot, the gas drawn in by the air pump can clean the inner cavity of the test chamber. When the gas is ejected from the air jet, it will also intermittently enter the inner cavity of the mobile rack, causing the airflow ejected from the air jet to weaken briefly and then instantly increase, and repeat this process multiple times. This makes the effect of flushing out the residue better, and the gas drawn in by the air pump can replace the spring to make the rotating plate reciprocate, preventing the spring from aging due to frequent compression, thereby reducing maintenance costs. In summary, the gas drawn in by the air pump can have two different effects when the mobile frame moves to different positions. The gas drawn in by the air pump can replace the spring to make the rotating plate rotate back and forth, and the gas drawn in by the air pump can make the impact plate move back and forth. Multiple impact forces are used to perform impact tests on materials to improve the test effect. The reciprocating movement of the impact plate can make the effect of spraying and flushing the residue better, which has a mutually reinforcing effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific diagrams. It should be noted that the embodiments and features in the embodiments of this application can be combined with each other unless they conflict.

[0017] See also Figure 1 - Figure 13 The embodiment of the present invention provides a technical solution: a compressive performance testing device, comprising a test box 1, an inlet 2 being formed at the upper end of the test box 1, a hydraulic cylinder 3 being fixedly connected to one end of the test box 1, and an extended end of the hydraulic cylinder 3 being movably inserted into the test box 1, a baffle 6 being slidably provided at the bottom end of the test box 1, and an electric push rod 5 being fixedly connected between the upper end of the baffle 6 and the side wall of the test box 1, an air pump 4 being fixedly connected to the side wall of the test box 1, and a hose 41 being connected to the air pump 4, and further comprising: A continuous testing mechanism 7 is used for quickly switching the test mode. The continuous testing mechanism 7 is arranged in the inner cavity of the test box 1 and includes a movable frame 71 slidably arranged in the inner cavity of the test box 1; The communication mechanism 8 is used to adjust the air pressure in the movable frame 71. The communication mechanism 8 is provided in the continuous testing mechanism 7. And the one-way mechanism 9 is used to perform impact testing on the material when the movable frame 71 is retracted. The one-way mechanism 9 is arranged in the continuous testing mechanism 7.

[0018] Specifically, since there is a gap between the slide plate 72 and the impact plate 74, the subsequent slide plate 72 can have a distance to accelerate, and thus can impact the material. When the movable frame 71 initially contracts, the gas drawn in by the air pump 4 passes through the setting of the connecting mechanism 8, so that the impact plate 74 can perform an impact test on the material during the contraction process of the movable frame 71, and there is no need to wait until the movable frame 71 is completely contracted before performing the impact test, thereby saving the overall time of the two tests and improving the test efficiency. In addition, the impact plate 74 can move back and forth to impact the material, and the impact force of the impact plate 74 on the material gradually increases. It is possible to use multiple impact forces to perform impact tests on the material, thereby improving the test effect. When the movable rack 71 moves to the point where the connecting groove 83 coincides with the straight groove opening 813 , the gas drawn in by the air pump 4 can clean the inner cavity of the test box 1 . When the gas is ejected from the air jet port 82 , the gas will also intermittently enter the inner cavity of the movable rack 71 , which causes the airflow ejected from the air jet port 82 to weaken briefly and then instantly increase, and repeat this process multiple times. This makes the effect of flushing out the residue better, and the gas drawn in by the air pump 4 can replace the spring to make the rotating plate 98 rotate back and forth, thereby preventing the spring from being aged due to frequent compression and reducing maintenance costs.

[0019] The gas drawn in by the air pump 4 can have two different effects when the movable frame 71 moves to different positions. The gas drawn in by the air pump 4 can replace the spring to make the rotating plate 98 rotate back and forth, and the gas drawn in by the air pump 4 can make the impact plate 74 move back and forth. Multiple impact forces are used to perform impact tests on the material, thereby improving the test effect. The reciprocating movement of the impact plate 74 can make the effect of spraying the residue better, thereby promoting each other.

[0020] In another embodiment provided by the present invention, the continuous testing mechanism 7 includes a movable frame 71, and the movable frame 71 is fixedly connected to the extended end of the hydraulic cylinder 3. A slide plate 72 is provided in the inner cavity of the movable frame 71 for horizontal sliding movement, and an insertion rod 73 is fixedly connected to the slide plate 72. A connecting frame 75 is movably sleeved on the outer side of the other end of the insertion rod 73, and the inner cavity of the connecting frame 75 is connected to the outer side of the connecting frame 75. An impact plate 74 is fixedly connected to the end of the connecting frame 75 away from the slide plate 72. The impact plate 74 is movably inserted in the movable frame 71, and a top block 76 is movably inserted in the side wall of the impact plate 74 close to the connecting frame 75.

The upper side of the impact plate 74 is located in the movable frame 71 and is provided with a counterweight block 78 that slides up and down, and the bottom end of the counterweight block 78 extends into the impact plate 74.

[0021] The connecting mechanism 8 includes an air jet 82 provided on the movable frame 71, and the air jet 82 is away from the hydraulic cylinder 3. A connecting plate 84 is fixedly connected to one side wall of the movable frame 71 close to the hydraulic cylinder 3. A plug-in plate 85 is movably inserted on the upper end of the connecting plate 84, and one end of the plug-in plate 85 is fixed to the inner wall of the test box 1. The other end of the plug-in plate 85 is movably inserted into the movable frame 71. A connecting cavity 88 is provided in the connecting plate 84. A connecting groove 83 is provided on the upper end of the connecting plate 84, and the upper end of the connecting groove 83 is connected to the air jet 82. A straight slot 813 is provided on the plug-in plate 85, and an outer ring groove 811 and an inner ring groove 812 are provided on the ring plate 92. There are ventilation pipe 1 86, ventilation pipe 2 87, blowing pipe 1 89 and blowing pipe 2 810, and the upper and lower parts of ventilation pipe 1 86, ventilation pipe 2 87, blowing pipe 1 89 and blowing pipe 2 810 are separated by a ring plate 92. One end of ventilation pipe 1 86 and ventilation pipe 2 87 are respectively connected to the cavities on the two opposite sides of the slide 72, and the other ends of ventilation pipe 1 86 and ventilation pipe 2 87 are connected to the outside of the movable frame 71. One end of blowing pipe 1 89 and blowing pipe 2 810 are respectively connected to the cavities on the two opposite sides of the slide 72, and the other ends of blowing pipe 1 89 and blowing pipe 2 810 are both connected to the connecting cavity 88, and the connecting cavity 88 is connected to the hose 41.

[0022] The air blowing pipe 1 89 , the air blowing pipe 2 810 and the outer ring groove 811 are all aligned with the outer side of the upper surface of the ring plate 92 , and the air vent pipe 1 86 , the air vent pipe 2 87 and the inner ring groove 812 are all aligned with the inner side of the upper surface of the ring plate 92 .

[0023] One end of the second ventilation pipe 87 and the second blowing pipe 810 is connected to the cavity on the same side of the slide 72, and one end of the first ventilation pipe 86 and the first blowing pipe 89 is connected to the cavity on the other side of the slide 72.

[0024] In another embodiment provided by the present invention, the one-way mechanism 9 includes an external tooth 81 fixed to the inner wall of the test box 1, and a gear 91 is meshed with one side of the external tooth 81. A rotating shaft 96 is fixed to the gear 91, and the rotating shaft 96 is rotatably set in the movable frame 71. A rotating ring 95 is provided on the outer side of the rotating shaft 96, and the rotating ring 95 is rotatably set in the movable frame 71. A ring plate 92 is fixed to the outer wall of the upper end of the movable frame 71, and a fixed ring 93 is rotatably set on the outer wall of the lower end of the rotating ring 95, and the fixed ring 93 is fixed in the movable frame 71. There is an air cavity between the fixed ring 93 and the rotating ring 95, and a connecting pipe 94 is connected to the fixing ring 93, and the connecting pipe 94 is connected to the air cavity. A shift block 97 is fixed to the outer wall of the rotating shaft 96, and a rotating plate 98 is rotatably set on the inner wall of the rotating ring 95. A guide groove 99 is connected between the rotating groove where the rotating plate 98 is located and the air cavity.

[0025] A plurality of shifting blocks 97 and rotating plates 98 are arranged in a ring shape at equal intervals.

[0026] Specifically, when the movable frame 71 moves toward the material and the gear 91 rotates, the shift block 97 will squeeze the rotating plate 98 into the rotating ring 95. When the movable frame 71 moves away from the material, the shift block 97 will drive the rotating plate 98 and the rotating ring 95 to rotate to perform an impact test. This setting is to enable the device to perform a static pressure test on the material first, and then perform an impact test, to prevent the impact force from being greater than the static pressure, causing damage to the material after the impact force test, and then making it impossible to perform a subsequent static pressure test, thereby ensuring the rationality of the test.

[0027] The gas blown in by the air pump 4 can enter the rotating groove where the rotating plate 98 is located through the connection of the hose 41, the connecting cavity 88, the connecting pipe 94 and the guide groove 99. When the rotating plate 98 is pressed inward, the rotating plate 98 is popped out again by the filling of gas. There is no need to set a spring. Only the gas generated by the air pump 4 is needed to make the rotating plate 98 rotate back and forth, preventing the spring from being frequently compressed and aged. There is no need to replace the spring subsequently, thereby reducing maintenance costs.

[0028] In another embodiment provided by the present invention, a wear-resistant rubber layer is provided on the outer wall of the rotating ring 95 , and the wear-resistant rubber layer contacts the inside of the movable frame 71 .

[0029] Specifically, the wear-resistant rubber layer is provided to prevent the rotating ring 95 from rotating when the rotating plate 98 is pressed inward.

[0030] Working principle: When in use, place the material to be tested from the inlet 2 into the inner cavity of the test box 1, then start the air pump 4 and the hydraulic cylinder 3, and the mobile frame 71 will be slowly squeezed toward the material by the extended end of the hydraulic cylinder 3. The material is squeezed by static pressure to test the compressive resistance of the material. If the material is damaged after squeezing, the impact force test is no longer required. The baffle 6 is opened by the electric push rod 5 to discharge the material. If the material is not damaged after squeezing, after recording the pressure value, the extended end of the hydraulic cylinder 3 is retracted to drive the mobile frame 71 to retract. When the mobile frame 71 moves in the direction away from the material, the outer teeth 81 will drive the gear 91 and the rotating shaft 96 to rotate counterclockwise. The rotation causes the shift block 97 to squeeze the rotating plate 98, and the rotating plate 98 drives the rotating ring 95 and the ring plate 92 to rotate. When the ring plate 92 rotates, the outer ring groove 811 first connects the upper and lower parts of the blowing pipe 2 810. At this time, the inner ring groove 812 connects the upper and lower parts of the ventilation pipe 1 86. As a result, the cavity on the side of the slide plate 72 close to the hydraulic cylinder 3 will be filled with gas under the action of the air pump 4, and the gas in the cavity on the side of the slide plate 72 away from the hydraulic cylinder 3 will be discharged, causing the slide plate 72 to move quickly toward the impact plate 74. The slide plate 72 presses the top block 76 inward, and the top block 76 pushes the lifting rod 77 and the counterweight block 78 upward, and the bottom end of the counterweight block 78 detaches from the impact plate 74, The impact plate 74 can be pushed outward from the movable frame 71 to perform an impact test on the material. The ring plate 92 continues to rotate, and the cavity on the side of the slide plate 72 away from the hydraulic cylinder 3 will be filled with gas under the action of the air pump 4, so that the impact plate 74 can be retracted, and the counterweight block 78 will be re-inserted downward into the impact plate 74 due to gravity, so that the impact plate 74 is locked. In the process of the movable frame 71 moving away from the material, the impact plate 74 can move back and forth to impact the material. As the movable frame 71 gradually moves away from the material, the distance that the impact plate 74 extends outward gradually increases, thereby causing the impact force of the impact plate 74 on the material to gradually increase, and a variety of impact forces can be used to impact the material. To improve the test effect, when the connecting groove 83 on the connecting plate 84 moves to the straight notch 813, the connecting groove 83, the straight notch 813 and the connecting cavity 88 are connected, so that the gas drawn in by the air pump 4 is ejected from the air jet 82, and then when the movable frame 71 is retracted, the electric push rod 5 is started, the baffle 6 will open, and the gas drawn in by the air pump 4 can flush out the residue in the test box 1 to prevent it from affecting the subsequent work. When the gas is ejected from the air jet 82, the gas will also intermittently enter the inner cavity of the movable frame 71, so that the airflow ejected from the air jet 82 will be temporarily weakened and then instantly strengthened, and repeated many times, which makes the effect of spraying out the residue better; When the moving frame 71 moves toward the material, the gear 91 rotates, and the shift block 97 squeezes the rotating plate 98 into the rotating ring 95. When the moving frame 71 moves away from the material, the shift block 97 drives the rotating plate 98 and the rotating ring 95 to rotate to perform the impact test. This setting is to enable the device to perform a static pressure test on the material first, and then perform an impact test, to prevent the impact force from being greater than the static pressure, causing damage to the material after the impact force test, and then making it impossible to perform the subsequent static pressure test, thereby ensuring the rationality of the test; The gas blown in by the air pump 4 can enter the rotating groove where the rotating plate 98 is located through the connection of the hose 41, the connecting cavity 88, the connecting pipe 94 and the guide groove 99. When the rotating plate 98 is pressed inward, the rotating plate 98 is popped out again by the filling of gas. There is no need to set a spring. Only the gas generated by the air pump 4 is needed to make the rotating plate 98 rotate back and forth, preventing the spring from being frequently compressed and aged. There is no need to replace the spring subsequently, thereby reducing maintenance costs.

[0031] A testing method for a lithogenic agent base material comprises the following steps: S1. Place the material to be tested into the inner cavity of the test chamber 1 from the inlet 2. Then start the air pump 4 and the hydraulic cylinder 3. The movable frame 71 will be slowly squeezed toward the material by the extended end of the hydraulic cylinder 3. S2. After recording the pressure value, the extended end of the hydraulic cylinder 3 is retracted, driving the movable frame 71 to retract. The impact force of the impact plate 74 on the material gradually increases. A variety of impact forces can be used to perform impact tests on the material, thereby improving the test effect. S3. When the movable frame 71 moves to the point where the connecting groove 83 coincides with the straight groove opening 813 , the gas drawn in by the air pump 4 can clean the inner cavity of the test box 1 . When the electric push rod 5 is started, the baffle 6 will open, and the gas drawn in by the air pump 4 can flush out the residue in the test box 1 .
