[0022] The force test assembly 4 includes a pressure sensor and a cylinder, which is used to apply pressure to the concrete block and detect the value of the pressure to determine the strength value of the concrete block;

[0023] The movable pushing device 7 includes a driving assembly 71 connected under the workbench 1, and the two output shafts of the driving assembly 71 are connected to a reciprocating screw 72, the reciprocating screw 72 is externally threadedly connected to a threaded cap 73, the threaded cap 73 is externally connected to a movable slider 74, the movable slider 74 is connected to a sliding sleeve 75, a sliding rod 76 is slidably connected inside the sliding sleeve 75, and one end of the sliding rod 76 is connected to a pushing plate 78.

[0024] A driving assembly 71 is used to control the rotation of a reciprocating screw rod 72. The reciprocating screw rod 72 cooperates with a threaded cap 73 to control the threaded cap 73 and a movable slider 74 to reciprocate in a horizontal direction.

[0025] The sliding sleeve 75 can push the sliding rod 76 to move along with the movement of the moving slider 74, and the sliding rod 76 can move forward and backward in the sliding sleeve 75;

[0026] An extrusion column 79 is connected to the push plate 78, and the extrusion column 79 is slidably arranged in the extrusion groove 6. The extrusion column 79 is set to be cylindrical, the push plate 78 is set to be L-shaped, and the extrusion groove 6 is composed of an inclined section and a straight section.

[0027] The extrusion groove 6 and the extrusion column 79 are used, and the inclined section of the extrusion groove 6 controls the extrusion column 79 to move in the front-back direction, so as to control the push plate 78 to move to the upper side of the rotating roller 9 or to separate from the rotating roller 9;

[0028] The other end of the sliding rod 76 is connected to a limiting plate 77 . The sliding rod 76 is configured as a rectangle, the limiting plate 77 is configured as a circle, and the movable slider 74 is slidably disposed in the sliding hole 5 .

[0029] The sliding rod 76 is rectangular to prevent the sliding rod 76 and the pushing plate 78 from rotating;

[0030] The movable bearing device 8 includes a movable plate 82 and a plurality of supporting rollers 81. The supporting rollers 81 are rotatably connected to two vertical plates 83. The vertical plates 83 are connected to the movable plate 82. The vertical plates 83 are slidably arranged in the workbench 1. Four extension plates 84 are connected to the side of the movable plate 82. The extension plates 84 are connected to an elastic component 85. The other end of the elastic component 85 is connected to the workbench 1.

[0031] A support roller 81 is used to support the concrete block to separate from the workbench 1, so as to facilitate the pushing and unloading operation of the concrete block. An elastic component 85 is used to apply an upward elastic force to the moving plate 82, so as to support the moving plate 82 and the support roller 81.

[0032] Four extension rods 86 are connected to the side of the workbench 1, and the other end of the extension rod 86 is connected to a contact rod 87. Both ends of the contact rod 87 are set as inclined surfaces. The position of the contact rod 87 corresponds to the position of the moving slider 74. Four support legs 2 are connected under the workbench 1.

[0034] The working principle of the utility model is:

[0035] When the strength of the concrete block needs to be tested, the concrete block is directly placed on the rotating roller 9, and then the driving assembly 71 is controlled to work. The driving assembly 71 controls the reciprocating screw 72 to rotate, and at the same time, the threaded cap 73 controls the movement of the movable slider 74 and the sliding sleeve 75. At the same time, the sliding sleeve 75 drives the push plate 78 to move toward the force test assembly 4 through the sliding rod 76. During the movement, the extrusion column 79 is squeezed and moved by the inclined section of the extrusion groove 6, so that the push plate 78 is controlled to move to the upper side of the rotating roller 9. The push plate 78 can smoothly contact the concrete block and push the concrete block to the position corresponding to the force test assembly 4. At the same time, the movable slider 74 squeezes the contact rod 87 and the movable The plate 82 moves down to make the concrete block contact with the workbench 1. The concrete block moves accurately to the position corresponding to the force test component 4 and remains stable. Then the drive component 71 is controlled to stop working. The force test component 4 works to apply pressure to the concrete block to test its strength. When the test is completed, the drive component 71 is controlled to work, and the reciprocating screw 72 drives the threaded nut 73 and the moving slider 74 to move away from the top frame 3. The moving slider 74 is separated from the contact rod 87, and the elastic component 85 controls the moving plate 82 and the supporting roller 81 to move up to push the concrete block to move. The extrusion groove 6 extrusion column 79 and the push plate 78 move so that they are not located on the upper side of the rotating roller 9, and then the concrete block can be taken out.
