[0019] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-4 The hardness testing device shown in the figure is used for the production of cement products, including a base 1, a support column 2 is fixedly connected to one side of the top of the base 1, a driving mechanism includes a driving motor 7 fixedly installed on the outside of the support column 2, and a first rod seat 8 is fixedly connected to both sides of the support column 2, and a threaded rod 9 is rotatably connected to the inside of one of the first rod seats 8, and two second rod seats 13 are fixedly connected to the top of the base 1 away from the support column 2. The other end of the threaded rod 9 is rotatably set inside one of the second rod seats 13, and a gear 11 is fixedly connected to the end of the threaded rod 9 away from the second rod seat 13. The movable frame 14 can be moved by the driving motor 7 to transport the cement bricks into the transparent cover 3 for testing. When loading, they only need to be placed inside the placement rack 16, which can prevent manual contact with the pressure head 4 during loading, avoiding the possibility of scratching fingers.

[0021] A moving mechanism is provided on the surface of the threaded rod 9, and the moving mechanism includes a moving frame 14 slidably connected to the surface of the threaded rod 9, and four lifting rods 15 are fixedly connected to the top of the moving frame 14, and the tops of the four lifting rods 15 are commonly fixedly connected to a placement frame 16. The placement frame 16 can place cement bricks that need to be tested, and at the same time play a restrictive role on the cement bricks. The placed cement bricks move during the hardness test, which affects the results of the hardness test.

[0022] The base 1 and the support column 2 are provided with a detection mechanism, which includes a pressure head 4 installed at the bottom end of the support column 2. The base 1 is internally slidably connected to a lifting screw rod 5, and the top of the lifting screw rod 5 is fixedly connected to a working platform 6. The lifting screw rod 5 can drive the working platform 6 to rise, thereby performing hardness detection on the cement bricks on the surface of the working platform 6.

[0023] A transparent cover 3 is installed on the top of the base 1. The pressure head 4, the lifting screw 5, and the working platform 6 are all located inside the transparent cover 3. The center of the working platform 6 is located directly below the pressure head 4. The transparent cover 3 can observe the hardness testing process of the cement brick at any time to prevent accidents. At the same time, it separates the testing mechanism from the staff to prevent the cement bricks from breaking and splashing onto the staff, causing damage to the staff.

[0024] A limiting rod 10 is fixedly connected between the other first rod seat 8 and the other second rod seat 13, and the movable frame 14 is also slidably connected to the outer surface of the limiting rod 10. The limiting rod 10 can limit the movable frame 14 to prevent the movable frame 14 from rotating with the rotation of the threaded rod 9, thereby ensuring that the movable frame 14 can move with the rotation of the threaded rod 9.

[0025] The end of the gear 11 away from the threaded rod 9 is fixedly connected to the adjusting knob 12. When cement bricks with unqualified hardness are crushed, debris will be stuck in the threaded rod 9. Larger debris requires the transparent cover 3 to be removed for cleaning, or the adjusting knob 12 to be rotated. Smaller debris can be manually adjusted through the adjusting knob 12 to make the debris fall off, thereby ensuring the normal operation of the moving mechanism.

[0026] Part of the gear 11 is located inside the support column 2, and the output end of the drive motor 7 is fixedly connected to the gear 11. The gear 11 located inside the support column 2 is engaged with the gear 11 fixedly connected to the output end of the drive motor 7. The drive motor 7 drives the moving mechanism to move, and the moving distance of the moving mechanism can be easily controlled to ensure that each cement brick being tested can be located below the pressure head 4.

[0027] Working principle: First, reset the device to zero, then place the cement bricks to be tested on the placement rack 16, and then set the hardness value through the control panel at one end of the support column 2, and then you can start the drive motor 7. The drive motor 7 will drive the gear 11 to rotate. Since the two gears 11 are meshed, the threaded rods 9 that are not in the same horizontal plane will also rotate, and under the restriction of the limiting rod 10, drive the mobile rack 14 to move. At this time, the mobile rack 14 is located on the outside of the working platform 6, and the placement rack 16 is located directly above the working platform 6. Through the control of the control panel, the working platform 6 will rise, and the placement rack 16 will be lifted up under the action of the lifting rod 15, so that the cement bricks to be tested will contact the indenter 4, and the results are obtained according to the depth and width of the indentation to determine whether the hardness of the cement bricks meets the standard.

[0028] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention.
