[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 A cement fineness sieve analyzer, including: bottom plate 1, bottom plate 1 upper surface front and rear sides are provided with two groups of support rods 3, and four groups of support rods 3 upper end are installed with screening bin 4, screening bin 4 right side is provided with first discharge outlet 5, and screening bin 4 left side lower end is provided with second discharge outlet 6, and bottom plate 1 upper surface is provided with shaking assembly.

[0024] The lower surface of the bottom plate 1 is provided with positioning seats 2 at four corners, and the lower ends of the four groups of positioning seats 2 are provided with rubber blocks. By arranging the positioning seats 2 with rubber blocks at the four corners of the lower surface of the bottom plate 1, the device can better adapt to different ground conditions. The rubber blocks have good anti-skid performance, and can keep the device stable even on smooth or inclined ground. The rubber blocks have a certain elasticity, which can effectively absorb and buffer the vibration generated during the operation of the device, protecting the structure of the device from damage.

[0025] The lower ends of the four groups of supporting rods 3 are hingedly arranged on the front and rear sides of the bottom plate 1, and the upper ends of the four groups of supporting rods 3 are hingedly arranged on the front and rear sides of the screening bin 4. The hingedly connected supporting rods 3 can freely move within a certain range during use, which helps to evenly distribute the force and reduces the risk of structural damage caused by local overload, facilitating the screening bin 4 to shake.

[0026] The inner lower surface of the screening bin 4 is arranged in a funnel structure, and the lower end of the funnel structure is connected with the second discharge port 6. The funnel structure effectively guides the material to the second discharge port 6 through the inwardly inclined side, reducing the spread or accumulation of the material in the bin and ensuring the correct guidance of the material flow. This design utilizes the gravity of the material itself to make the material flow more smoothly, which can maximize the reduction of material blockage during unloading and ensure continuous material flow.

[0027] The screening bin 4 is provided with a screen 7 inside, which is arranged in an inclined structure and connected with the first discharge port 5 at the lower end. The inclined design utilizes gravity to promote the downward sliding of the material, reducing the accumulation of the material on the screen 7 and improving the continuity and stability of the screening. Compared with the horizontally placed screen 7, the inclined screen 7 can provide a larger screening area in the same space, which helps to increase the material processing capacity per unit time. The inclined structure facilitates the natural stratification of the material under the action of gravity, making it easier for particles meeting the particle size requirements to pass through the screen holes, while the particles that do not meet the requirements flow downward, improving the screening accuracy. The connection with the first discharge port 5 facilitates the automation of the screening process and reduces the dependence on manual labor.

[0028] The shaking assembly includes a drive motor 8 fixedly installed on the upper surface of the bottom plate 1 on the right side, and a rotating rod 9 is installed on the front and rear sides of the drive motor 8. The distal ends of the two groups of rotating rods 9 are connected with adjusting rods 11, and the left ends of the two groups of adjusting rods 11 are connected to the left side of the screening bin 4. The right ends of the two groups of adjusting rods 11 are hingedly connected to the distal ends of the two groups of rotating rods 9 through a crank 10, and the left ends of the two groups of adjusting rods 11 are hingedly connected to the front and rear sides of the screening bin 4. Turning on the drive motor 8 drives the rotating rod 9 to rotate, thereby driving the right end of the hingedly arranged adjusting rod 11 to shake through the crank 10, and further causing the left end of the adjusting rod 11 to drive the screening bin 4 to shake, thereby driving the screen 7 in the screening frame to screen the cement.

[0029] Working principle: by introducing cement into the screening bin 4, by opening the drive motor 8, drive rotating rod 9 rotation, thereby through the crank 10 drive articulated adjustment rod 11 right end to shake, and then make the adjustment rod 11 left end drive screening bin 4 through the hinged support rod 3 to shake, through the screen 7 in the screening bin 4 of cement screening, then through the screen 7 of the inclined structure makes the screened cement through the first discharge port 5 removal or fall to the screening bin 4 downside, then through the second discharge port 6 will be screened cement discharge.
