[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1

[0035] Please see Figure 1-8As shown, a pressure testing machine for cement strength includes a body 1 and a hydraulic plate 5, wherein the hydraulic plate 5 is disposed on the body 1 and is driven by a motor to compress cement blocks.

[0036] The main body 1 is provided with a protective wall 2, and there are three protective walls 2, which are respectively arranged around the hydraulic plate 5. The surface of the main body 1 is connected to a protective door 3 by a hinge.

[0037] The surface of the main body 1 is provided with a base 9, the surface of the base 9 is provided with a support plate 8, and the cement block is placed on the support plate 8;

[0038] The base plate 6 is rotatably connected to the surface of the main body 1, and a sponge wiper 11 is provided on the surface of the base plate 6;

[0039] A support plate 13 is fixedly connected to the surface of the hydraulic plate 5, and a guide shaft 18 is fixedly connected to the surface of the support plate 13.

[0040] The bottom plate 6 has a guide groove 21 on its surface, and the guide shaft 18 is slidably connected through the guide groove 21.

[0041] During operation, the cement block to be tested is first placed on the tray 8, and then the hydraulic plate 5 is pressed down by the motor. At this time, the cement is squeezed by the hydraulic plate 5 to test the strength of the cement. When the hydraulic plate 5 is pressed down or raised, it will drive the guide shaft 18 to slide in the base plate 6. At the same time, the base plate 6 rotates and drives the sponge wiping 11 to make a 1 / 4 circumferential reciprocating motion. The sponge wiping 11 on the surface of the base plate 6 cleans the impurities adhering to the surface of the protective door 3, so as to prevent the debris after the cement block is crushed from adhering to the protective door 3 and affecting the observation of the staff.

[0042] A vertical plate 7 is fixedly connected to the surface of the base plate 6. There are two vertical plates 7. A fixed shaft 16 is rotatably connected between the two sides of the vertical plates 7 that are close to each other. The sponge 11 is fixedly connected to the surface of the fixed shaft 16. The sponge 11 is polygonal. A lever 17 is fixedly connected to the surface of the fixed shaft 16. A secondary plate 15 is provided on the surface of the hydraulic plate 5 for actuating the lever 17. A main rod 12 is fixedly connected to the surface of the hydraulic plate 5. The secondary plate 15 is rotatably connected to the main rod 12 through a hinge. A spring is fixedly connected to the surface of the main rod 12. The end of the spring away from the main rod 12 is fixedly connected to the surface of the secondary plate 15.

[0043] During operation, when the base plate 6 rotates clockwise, the auxiliary rod will move the upright plate 7. At this time, the upright plate 7 will drive the fixed shaft 16 to rotate. Simultaneously, in conjunction with the polygonal sponge 11, the utilization rate of the sponge 11 can be improved, avoiding waste. At the same time, through the rotation of the sponge 11, the clean side of the sponge 11 can be made to adhere to the surface of the protective door 3, thereby improving the cleaning effect. When the base plate 6 rotates counterclockwise again, the lever will squeeze the auxiliary rod, causing it to rotate around the hinge, thereby preventing the auxiliary rod from getting stuck on the surface of the lever plate 17.

[0044] The fixed shaft 16 is rotatably connected to the surface of the vertical plate 7 by a spring, and a positioning block 19 is slidably connected to it. A positioning groove is provided on the surface of the vertical plate 7 relative to the positioning block 19. An arc corner is provided on one side of the positioning block 19. A guide groove 21 is provided on the surface of the vertical plate 7. The guide groove 21 is inclined.

[0045] During operation, the rotation of the fixed shaft 16 will cause the positioning groove to squeeze the positioning block 19, causing the positioning block 19 to retract into the fixed shaft 16. At this time, the fixed shaft 16 continues to rotate, so that the positioning block 19 fits into the guide groove 21. Through the inclined design of the guide groove 21 and the spring at the bottom of the positioning block 19, the guide block can be squeezed to continue rotating and reset, which improves the fixing effect of the sponge 11. At the same time, the positioning block 19 with a rounded corner on one side positions the fixed shaft 16 to avoid reverse rotation.

[0046] Example 2

[0047] Please see Figure 9-10 As shown in the comparative embodiment one, as another embodiment of this utility model, the pallet 8 is rotatably connected to the body 1 via a hinge, a protective cover 22 is fixedly connected to the surface of the pallet 8, a horizontal shaft 25 is fixedly connected inside the protective cover 22, a scroll 27 is rotatably connected to the surface of the horizontal shaft 25 via a torsion spring 23, an impact ball 26 is fixedly connected to the surface of the scroll 27 via a spring, a pull rope 24 is fixedly connected to the surface of the scroll 27, and one end of the pull rope 24 away from the scroll 27 is fixedly connected to the surface of the base plate 6, and several impact balls 26 are provided;

[0048] During operation, after the cement block is tested, the cement residue needs to be cleaned up. At this time, the pallet 8 is rotated directly by the hinge, so that the pallet 8 rotates around the hinge. At this time, the cement debris on the surface of the pallet 8 will be poured out. The pallet 8 can collect most of the cement impurities, and then pouring them out by the rotating pallet 8 can greatly improve the cleaning efficiency. While the pallet 8 is rotating, the pull rope 24 will be stretched, so that the pull rope 24 drives the roller 27 to rotate. At this time, the impact ball 26 on the surface of the roller 27 will hit the bottom surface of the pallet 8, and the impurities on the surface of the pallet 8 can be shaken off through vibration.
