[0032] The driving mechanism includes a fixed rope 18, a slide groove 19 is provided on both sides of the support frame 2, a slider 20 is slidably connected to the inner side of the slide groove 19, a straight rod 21 is slidably connected to the side wall of the slider 20, an inclined groove 22 is provided on the top of the straight rod 21 close to one side, a lower spring 23 is fixedly connected between the outer wall of the straight rod 21 and the side wall of the slider 20, the fixed rope 18 is fixedly connected to the bottom of the slider 20, the other end of the fixed rope 18 passes through the support frame 2 and the inner side of the detection table 1 and is fixedly connected to the side wall of the rack 15, and a reset spring 24 is fixedly connected between the inner side of the adjustment cavity 9 and the rack 15;

[0033] Push plates 25 are fixedly connected to the side walls of the shielding cover 10 and at positions corresponding to the straight rods 21. A right-angle block 26 that fits the inclined surface of the inclined groove 22 is fixedly connected to the inner side of the support frame 2 and above the straight rods 21. The right-angle blocks 26 and the push plates 25 are staggered.

[0034] When testing the strength of the wooden floor, first place the wooden floor to be tested in the placement groove 8 on the discharge plate 7, then control the hydraulic telescopic cylinder 3 to start and drive the fixed rod 11 to move downward, and then under the thrust of the upper spring 13, the shielding cover 10 will be driven to move to the testing platform 1 to block the outside of the waste opening 5. At this time, the shielding plate 6 is in a closed state, so as to ensure that the debris generated by the subsequent detection of the fracture will not splash at will. At the same time, the downward movement of the shielding cover 10 will drive the push plate 25 to pass over the straight rod 21, and the inclined groove 22 will be The push plate 25 moves out of the side of the straight rod 21, and the straight rod 21 is pushed back to its original position under the elastic force of the lower spring 23. Then, the hydraulic telescopic cylinder 3 is driven to move the detection head 4 to the top of the wooden floor, and the wooden floor is pressed downward for detection. Meanwhile, the shielding cover 10 is restricted from moving by the detection platform 1, and the upper spring 13 is gradually compressed. After the detection is completed, the debris splashed by the wooden floor will be shielded by the shielding cover 10 and the shielding plate 6.

[0035] Finally, the hydraulic telescopic cylinder 3 is controlled to be retracted to drive the fixed rod 11 to move upward, thereby gradually driving the upper spring 13 to reset. Then, when the bottom ring 32 moves to the top of the shielding cover 10, it will drive the shielding cover 10 to move upward, and at the same time drive the push plate 25 to move under the straight rod 21, and then drive the straight rod 21 to move upward, followed by driving the rack 15 to move to both sides through the fixed rope 18, and at the same time drive the adjustment frame 16, the connecting block 17 and the discharge plate 7 to move to both sides, and then the wooden floor that loses its support falls from the discharge plate 7, and at the same time gradually compresses the reset spring 24. At this time, the movement of the rack 15 will drive the meshing gears The wheel 14 rotates, thereby driving the baffle plate 6 to flip and open the waste opening 5, and then the fallen wooden floor and debris fall from the waste opening 5 into the collection box 31, realizing automatic cleaning of the waste. As the push plate 25 continues to move, when the straight rod 21 is pushed to the bottom of the right-angle block 26, the inclined surface on the right-angle block 26 will squeeze the inclined groove 22, thereby pushing the straight rod 21 to slide to both sides and compressing the lower spring 23, moving the straight rod 21 from above the push plate 25, and then losing the thrust, and the slider 20 is pulled to reset by the elastic force of the reset spring 24, and at the same time, the rack 15, the adjustment frame 16, the baffle plate 6 and the discharge plate 7 are pushed to reset.

[0036] In order to improve the service life of the device, an L-shaped groove 27 is opened inside the detection table 1 and at a position corresponding to the fixed rope 18 and is connected to the adjustment chamber 9. A pair of guide rollers 28 are rotatably connected to the inside of the L-shaped groove 27, and the rotation direction of the guide rollers 28 is set according to the pulling direction of the fixed rope 18, and the fixed rope 18 passes through the outer wall of the guide rollers 28. Through the setting of the guide rollers 28, the sliding of the fixed rope 18 can be guided to avoid the fixed rope 18 from being subjected to fine friction, causing the fixed rope 18 to be often worn, thereby affecting the service life of the device.

[0037] In order to collect the fallen wooden floor, a bottom plate 29 is fixedly connected to the bottom of the testing table 1, and a pair of angle irons 30 are fixedly connected to the top of the bottom plate 29. Through the setting of the angle irons 30, the position of the collection box 31 can be restricted to prevent the fallen wooden floor from falling elsewhere, thereby improving the practical performance of the device. A collection box 31 is provided on the bottom plate 29 and below the waste port 5. Through the setting of the collection box 31, the fallen wooden floor can be collected, which is conducive to subsequent unified processing.

[0038] In order to improve the stability of the device during operation, a bottom ring 32 for limiting is fixedly connected to the outer wall of the fixed rod 11 and located on the inner side of the shielding cover 10. Through the setting of the bottom ring 32, the downward sliding position of the shielding cover 10 on the fixed rod 11 can be limited to prevent the shielding cover 10 from sliding off the fixed rod 11, thereby improving the stability of the device during operation.

[0039] In order to facilitate the inspectors to observe the stress condition of the wooden floor, an observation groove 33 is opened on the front side of the shielding cover 10, and a high-strength transparent glass 34 is fixedly connected to the inside of the observation groove 33. The high-strength transparent glass 34 allows the inspectors to observe the stress condition of the wooden floor from the outside, which is conducive to recording the entire inspection process. Moreover, by using the high-strength transparent glass 34, there is no need to worry about the broken debris of the wooden floor shattering the glass.

[0040] In order to be able to automatically discharge wooden floors of different lengths, threaded rods 35 are rotatably connected to the inner side of the adjustment frame 16, and the threads of the threaded rods 35 are arranged in opposite directions. The threaded rods 35 all penetrate the inner side wall of the threaded connection block 17, and the threaded rods 35 are arranged on the side wall of the adjustment frame 16. A rectangular block 36 is fixedly connected to the side wall of one of the threaded rods 35, and a rectangular groove 37 adapted to the rectangular block 36 is opened on the side wall of the other threaded rod 35. Through the arrangement of the rectangular groove 37 and the rectangular block 36, not only the connection between the two threaded rods 35 can be ensured, but also when the cleaning mechanism is running, the rectangular block 36 will be driven to move out of the rectangular groove 37. At this time, since the threaded connection has a self-locking function, the connection block 17 will not move arbitrarily to drive the threaded rod 35 to rotate. Then, when resetting, the rectangular block 36 will be driven to insert into the rectangular groove 37 to ensure subsequent adjustment.

[0041] A connecting cavity 38 is provided inside the adjusting frame 16, wherein a side wall of a threaded rod 35 passes through the inner side of the connecting cavity 38 and is fixedly connected to a lower conical tooth 39, and an upper conical tooth 40 meshing with the lower conical tooth 39 is rotatably connected to the top of the connecting cavity 38, and a rotating rod 41 is fixedly connected to the top of the upper conical tooth 40 and is arranged through the top of the detection platform 1, and the rotating rod 41 is convenient for rotating the threaded rod 35 to quickly adjust the spacing between the discharge plates 7, thereby improving the convenience of the device, and a moving groove 42 for movement is provided at the top of the detection platform 1 and at a position corresponding to the rotating rod 41, and the setting of the moving groove 42 can avoid hindering the movement of the rotating rod 41 when the cleaning mechanism is running, thereby avoiding affecting the normal operation of the device;

[0042] When the spacing between the discharge plates 7 needs to be adjusted according to the length of the wooden floor to ensure that the tested wooden floor can fall smoothly from the discharge plates 7, the upper conical teeth 40 are driven to rotate by rotating the rotating rod 41, which in turn drives the meshing lower conical teeth 39 to rotate, and then drives one of the threaded rods 35 to rotate. At this time, since the rectangular block 36 between the threaded rods 35 is inserted in the rectangular groove 37, it will drive the other threaded rod 35 to rotate at the same time, and since the threads of the two threaded rods 35 are in opposite directions, it will drive the two threaded connection blocks 17 to move toward or away from each other, thereby adjusting the spacing between the discharge plates 7 and ensuring that when the cleaning mechanism is running, the wooden floor can fall smoothly and be discharged from the waste port 5.

[0043] In order to improve the stability of the device during operation, a pair of guide rods 43 are fixedly connected to the inner side of the adjustment frame 16 and pass through the inner wall of the connecting block 17. Through the setting of the guide rods 43, it can play a guiding role in the process of the threaded rod 35 rotating and driving the connecting block 17 to move, thereby preventing the connecting block 17 from rotating with the threaded rod 35, thereby improving the stability of the device during operation.
