[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 , 2 As shown in Figures 3, 4 and 5, the utility model provides a technical solution: a cement mortar compressive strength testing device, comprising: a support platform 1; a support seat 13 is fixedly connected to the top of the support platform 1, and a feeding channel 14 is inclinedly provided at the bottom of the support seat 13; a mounting frame 3 is installed on the top of the support seat 13 by bolts, and a hydraulic cylinder 4 is fixedly installed on the top of the mounting frame 3; a temperature adjustment component is placed on both sides of the top of the support platform 1, and the temperature adjustment component includes an air duct 7 movably arranged on the top of the support platform 1, a semiconductor refrigeration plate 8 is fixedly connected to the top of the air duct 7, and an electric heating wire 11 is installed at the end of the air duct 7; a water pipe 18 is rotatably installed above the air duct 7, a nozzle is installed on the outside of the water pipe 18, and an angle adjustment part is provided at the end of the water pipe 18 for adjusting the humidity of the detection environment and reducing dust.

[0027] It should be noted that the utility model places the cast sample on the top of the support plate 6, and then pressurizes the sample through the hydraulic cylinder 4, and observes its state under different pressure conditions through the observation window. During the inspection, the inside of the protective cover 2 is humidified by connecting the water pump and the water pipe 18. According to the dryness and humidity meter inside the protective cover 2, the internal humidity changes, which can simulate the pressure resistance state of the sample under rainy days or different humidity conditions, and the temperature change inside the protective cover 2 is changed by the cooperation of the semiconductor refrigeration sheet 8 and the heating wire 11 with the fan 10, so that the compressive strength of the sample under different temperature conditions can be measured. After the experiment is completed, the crushed material falls into the discharge channel 14 and is transported to the bottom, so as to facilitate the collection of the material. The equipment is collected, and dust is reduced inside the protective cover 2 through the water pipe 18 and the nozzle. The equipment is equipped with electric heating wires and semiconductor refrigeration sheets, which can adjust the temperature of the test environment. The hardening process and strength development of cement mortar will be different. The temperature adjustment function of the equipment can simulate the actual conditions under different ambient temperatures and more accurately evaluate the pressure resistance of cement mortar. The equipment can perform pressure resistance tests on samples under different humidity conditions by setting nozzles, and can simulate the actual conditions under different humidity conditions. The pressure resistance of cement mortar under different humidity conditions is tested. The temperature and humidity adjustment functions can better simulate environmental changes under actual use conditions, thereby improving the accuracy of the test and reducing the workload and possibility of errors of operators.

[0028] See also Figure 1 , 2 As shown, a protective cover 2 is installed on the top of the support platform 1. The protective cover 2 is provided with two sliding doors, and an observation glass is provided in the middle of the sliding doors.

[0029] It should be noted that the setting of the protective cover 2 of the utility model can provide safety protection for the test process. During the sample test, the protective cover can prevent the splashing and scattering of materials and protect the safety of the operator. The protective cover can also prevent external interference and pollution, improve the accuracy and reliability of the test, and the setting of the sliding door allows the operator to easily enter and leave the equipment to place and remove samples. The sliding door can be opened and closed as needed to meet the requirements of sample loading and sampling. An observation glass is provided in the middle of the sliding door, through which the operator can observe the pressure condition and changes of the sample in real time.

[0030] See also Figure 1 , 2 As shown in Figures 3, 4 and 5, the end of the material discharge channel 14 is rotatably connected with a flip cover plate 15.

[0031] It should be noted that the utility model has a flip cover 15 rotatably arranged at the end of the feed channel 14. During testing, the flip cover 15 can be flipped over to cover the end of the feed channel 14. After the test is completed, the flip cover 15 is opened to allow debris to flow out along the feed channel 14 for easy collection. In this way, the feed channel 14 is blocked, and a simple seal is achieved inside the protective cover 2, thereby ensuring the temperature adjustment inside the protective cover 2.

[0032] See also Figure 4 As shown, the support seat 13 is connected to the support plate 6 by sliding up and down through a slide rod, and a pressure sensor is installed between the support plate 6 and the support seat 13.

[0033] It should be noted that the utility model installs a pressure sensor between the support plate 6 and the support seat 13, which can monitor the pressure of the sample in real time. The pressure sensor can measure the pressure applied by the sample on the support seat and provide a digital pressure signal, thereby providing accurate pressure data to help evaluate the compressive strength performance of the cement mortar. Through the setting of the pressure sensor, the pressure applied by the sample can be monitored in real time, and the data can be fed back to the detection equipment or monitoring system, which can provide real-time pressure change curves and data records to help detect and analyze the performance of the sample in different time periods and loading processes. Since the height of the support plate 6 can be adjusted, the compaction height of the sample can be set as needed. Through the monitoring of the pressure sensor, the pressure values ​​of different samples can be compared and evaluated for parameter comparison and performance analysis.

[0034] See also Figure 3 , 4 As shown, both sides of the top of the support platform 1 are fixedly connected with a pitch-adjusting cylinder 12, the output end of the pitch-adjusting cylinder 12 is fixedly connected to the air duct 7, the air duct 7 is slidably connected to the protective cover 2, the cooling end of the semiconductor refrigeration plate 8 faces one side of the air duct 7, a plurality of metal fins 9 are equidistantly arranged inside the air duct 7, the ends of the metal fins 9 are connected to the cooling end of the semiconductor refrigeration plate 8, and a fan 10 is installed inside the air duct 7.

[0035] It should be noted that the utility model can adjust and control the air temperature at the duct outlet through the combination of semiconductor refrigeration sheet 8 and metal fin 9. The cooling effect of semiconductor refrigeration sheet 8 can reduce the temperature of the air at the duct outlet when it is blown to the workpiece, ensuring that the required temperature conditions are provided during the test. A plurality of metal fins 9 are equidistantly arranged inside the duct 7. These fins can increase the flow area and contact area of ​​the air and improve the cooling effect. When the fan 10 is started, the workpiece is blown through the metal fins 9 to evenly transfer the cold air to the surface of the workpiece to achieve cooling. The distance-adjusting cylinder 12 can flexibly adjust the position of the duct outlet from the workpiece. According to the specific test requirements and the shape and size of the workpiece, the distance between the air outlet and the workpiece can be adjusted to ensure uniform cooling during the test.

[0036] See also Figure 5 As shown, the angle adjustment part includes an angle adjustment gear 19 fixedly connected to the end of the water pipe 18, an electric telescopic rod 16 is fixedly connected to the side of the air duct 7, an output end of the electric telescopic rod 16 is fixedly connected to a pitch adjustment rack 17, the pitch adjustment rack 17 is meshed and connected with the angle adjustment gear 19, and a limiting sleeve 5 is fixedly connected to one side of the air duct 7 and is slidably connected to the pitch adjustment rack 17.

[0037] It should be noted that the angle-adjusting gear of the utility model is fixedly connected to the end of the water pipe 18, and the output end of the electric telescopic rod 16 is fixedly connected with the pitch-adjusting rack 17, which is meshed with the angle-adjusting gear. The telescopic action of the electric telescopic rod drives the movement of the pitch-adjusting rack. The telescopic action of the electric telescopic rod and the position of the pitch-adjusting rack can control the angle of the water pipe 18 and realize the angle of the nozzle. The limit sleeve 5 limits the stable lifting and lowering of the pitch-adjusting rack. When the electric telescopic rod 16 drives the pitch-adjusting rack 17 to move, the meshing action of the pitch-adjusting rack and the angle-adjusting gear 19 enables the nozzle of the water pipe 18 to adjust the angle. By adjusting the water spraying angle of the water pipe, the internal humidity can be adjusted, and the dust reduction treatment inside can also be tested.
