DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following is a description of the preferred embodiments of the present invention with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] Embodiment: As Figures 1-4As shown in the figure, the utility model provides a technical solution for a performance detection device of concrete, which includes a support platform 1. On both sides of the top of the support platform 1, there are installed columns 2. Between the tops of the two columns 2, a bidirectional screw 3 is rotatably installed. Between the two columns 2 and at the bottom of the bidirectional screw 3, there is installed a limit sliding tube 4. At both ends of the bottom of the bidirectional screw 3 and the limit sliding tube 4, there are connected extrusion plates 5. The bidirectional screw 3 is connected to the extrusion plate 5 through a threaded hole. The limit sliding tube 4 is slidably connected to the extrusion plate 5. On the two opposite surfaces of the two extrusion plates 5, there are installed pressure sensors. The output end of the pressure sensor is electrically connected to the data input end of an external controller. When the extrusion plate 5 extrudes the concrete block, it can feedback the pressure data to the controller, and the compressive performance of the concrete block can be determined by the controller's judgment of the pressure data. The cross-sectional shape of the limit sliding tube 4 is rectangular. Under the limiting and guiding action of the limit sliding tube 4, when the bidirectional screw 3 rotates, it can drive the extrusion plate 5 to move along the limit sliding tube 4. The outer side of the limit sliding tube 4 is a smooth surface, which reduces the frictional resistance between the limit sliding tube 4 and the extrusion plate 5. On the top of one side of a column 2, there is installed an extrusion motor 6. The output end of the extrusion motor 6 is connected to one end of the bidirectional screw 3. In the middle of one side of the top of the support platform 1, there is installed a feeding electric push rod 7. The output end of the feeding electric push rod 7 is connected to a feeding plate 8. On one side of the top of the feeding plate 8, there is connected an assembly frame 9. At the bottom of both ends of the assembly frame 9, there are installed cleaning brushes 10. At the bottom of the assembly frame 9, there is connected a scraping plate 11. The bottom surface of the scraping plate 11 is in contact with the top surface of the support platform 1. In the middle of the other side of the top of the support platform 1, there is a through opening 12 for discharging materials. At the bottom of the support platform 1 and at the bottom of the through opening 12 for discharging materials, there is installed a collection box 13. One end of one side of the limit sliding tube 4 is connected to one end of a water delivery pipe 14. The other end of the water delivery pipe 14 is connected to the output end of an external water pump. The bottom of the limit sliding tube 4 is evenly provided with water spraying holes 15. Under the connection effect of the water delivery pipe 14, the external water pump can deliver water into the limit sliding tube 4, and finally flow out through the water spraying holes 15. The sprayed water can clean the support platform 1, the extrusion plate 5 and the cleaning brushes 10;

[0024] On the top of the support platform 1 and on one side of the feeding electric push rod 7, there is installed a guiding plate 16. On the tops of the two guiding plates 16, there are installed pushing sliding rods 17. Between the two pushing sliding rods 17, there is a sliding connection with a delivery rod 18. The outer side of the pushing sliding rod 17 is a smooth plane, which reduces the frictional resistance between the pushing sliding rod 17 and the delivery rod 18. In the middle of the bottom of the delivery rod 18, there is connected a delivery plate 19. On the top of the support platform 1 and at one end of the guiding plate 16, there is installed a delivery motor 21. The output end of the delivery motor 21 is connected to one end of a delivery screw 20. One end of the delivery rod 18 is connected to the outside of the delivery screw 20 through a threaded hole. The input ends of the extrusion motor 6, the feeding electric push rod 7 and the delivery motor 21 are electrically connected to the output end of an external controller. The input end of the external controller is electrically connected to the output end of an external power supply. By controlling each electrical component through the external controller, it is convenient to carry out automatic control of the device.

[0025] Working principle and usage process of the utility model: When detecting concrete blocks, first arrange multiple concrete blocks to be detected between two guiding plates 16. The delivery motor 21 runs step by step, driving the delivery screw rod 20 to rotate. Under the limiting and guiding action of the pushing slide rod 17, the delivery motor 21 drives the delivery rod 18 and the delivery plate 19 to move. The delivery plate 19 pushes the concrete blocks between the two guiding plates 16 to move. When the top concrete block moves to the position of the feeding plate 8, the feeding electric push rod 7 operates, driving the feeding plate 8 to move, and then pushing the concrete block to move between the two pressing plates 5. The pressing motor 6 starts, driving the bidirectional screw rod 3 to rotate. Under the limiting and guiding action of the limiting slide tube 4, the rotation of the bidirectional screw rod 3 drives the two pressing plates 5 to approach each other, thereby detecting the compressive strength of the concrete block. After the detection of the concrete block is completed, the pressing motor 6 drives the pressing plate 5 to return to its original position. The feeding electric push rod 7 drives the feeding plate 8 to continue pushing. The scraping plate 11 pushes the detected concrete block to the position of the discharge opening 12. The detected concrete block falls into the collection box 13. After the detected concrete block falls into the collection box 13, the feeding electric push rod 7 drives the feeding plate 8 to return to its original position;

[0026] Under the connection and driving action of the assembly frame 9, when the feeding electric push rod 7 drives the scraping plate 11 to move, it also drives the cleaning brush 10 to move. During the movement of the scraping plate 11, it can push the concrete fragments falling on the top surface of the support table 1 into the collection box 13. At the same time, the movement of the cleaning brush 10 can clean the opposite surfaces of the two pressing plates 5, preventing concrete fragments from adhering to the opposite surfaces of the two pressing plates 5. There is no need for manual cleaning of the support table 1 and the pressing plates 5, reducing the manual labor intensity. When the cleaning brush 10 needs to be cleaned, under the connection action of the water delivery pipe 14, an external water pump can deliver water into the limiting slide tube 4 and finally spray out through the spray holes 15. The sprayed water can clean the support table 1, the pressing plates 5, and the cleaning brush 10, enabling the device to have a self-cleaning function without manual cleaning, further reducing the manual labor intensity;

[0027] At the same time, by repeating the above operation steps and the delivery motor 21 running step by step, multiple concrete blocks can be continuously detected, and the detection efficiency is higher.

[0028] Finally, it should be noted that the above are only preferred examples of the utility model and are not used to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
