The inclination angle of the screening block 16 will drive the rolling cement clinker to cross the connecting opening 13 and enter the interior of the storage frame 3, so as to collect the screened cement clinker for secondary processing.

[0041] Working principle: Please refer to Figure 1-Figure 7As shown, when in use, the staff will first pour the cement clinker into the working box 1 through the feeding hole 21. The cement clinker poured into the working box 1 will accumulate on the top surface of the screening block 16. Then the staff will start the driving motor 4 and use the rotating shaft of the driving motor 4 to drive the fixed frame 15 to move inside the working box 1. During the movement of the fixed frame 15, the existence of the connecting port 13 can limit the movement of the fixed frame 15 inside the working box 1. Since the screening block 16 is in an inclined state, the cement clinker will be driven to roll on the surface of the screening block 16, thereby increasing the screening efficiency of the screening block 16 for the cement clinker. In this process, the shielding plate 26 will fall on the screening plate due to its own weight. The top surface of the selection block 16 can be prevented from leaking into the external environment through the connecting port 13 on the top surface of the screening block 16 during the activity of the fixed frame 15. After the screening is completed, the staff will apply a force to the flip rod 35 to make the flip rod 35 in a vertical state inside the storage groove 34, and use the vertical flip rod 35 to support the position of the blocking block 17 on the top surface of the working box 1, thereby fixing the position of the baffle plate 26 inside the accommodating hole 25, preventing the baffle plate 26 from continuing to block the top surface of the screening block 16. The inclination angle of the screening block 16 will drive the rolling cement clinker to cross the connecting port 13 and enter the interior of the storage frame 3, so as to facilitate the collection of these screened cement clinkers for secondary processing.

[0042] By setting the connecting block 24, the connecting block 24 can be snapped into the inside of the limiting opening 32, so as to preliminarily determine the position between the connecting block 24 and the fixing block 23. At the same time, when the connecting block 24 is snapped into the inside of the limiting opening 32, the limiting block 33 will be snapped into the inside of the snap-in groove 31, so as to fix the position between the working box 1 and the storage frame 3. At the same time, it is also convenient for the staff to separate the working box 1 and the storage frame 3. In the process of the staff carrying the storage frame 3, the staff's palm will hold the surface of the handle 29. When the staff lifts the handle 29, due to the change in the direction of the force, the mounting rod 30 will rotate synchronously inside the penetration hole 28, so as to adjust the position state of the handle 29.

[0043] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
