[0039] In the above embodiments, see the attached Figure 3 The auxiliary screening mechanism 9 includes a screening plate 91, a first hinge seat 92, a second hinge seat 93, a force sensor 94, and an electric push rod 95. The two screening plates 91 are symmetrically arranged in the crushing box 14. The two sides of the two screening plates 91 are respectively connected to the corresponding side walls of the crushing box 14 through hinges 15 for vertical rotation. An inclined electric push rod 95 is arranged between each screening plate and the side wall of the crushing box 14. The lower telescopic end of the electric push rod 95 is vertically hingedly connected to the first hinge seat 92 set on the edge of the upper surface of the screening plate 91, the upper end of the electric push rod 95 is connected to the first tension end of the force sensor 94, and the second tension end of the force sensor 94 is hingedly connected to the second hinge seat 93 set on the side wall of the crushing box 14.

[0040] In the above embodiments, see the attached Figure 4 , 5 The crushing blade 11 includes a fixed sleeve 111 and crushing plates 112 symmetrically arranged on both sides of the fixed sleeve 111. The crushing plates 112 are detachably connected to the fixed sleeve 111. Two racks 113 are symmetrically arranged at the upper and lower ends of the crushing plate 112.

[0041] In the above embodiments, see the attached Figure 4 , 5A screw positioning through hole 101 is arranged inside the crushing plate 112 along the length direction, and a positioning threaded hole 102 matching the screw positioning through hole 101 is arranged on the outer wall of the fixed sleeve 111. The crushing plate 112 is screwed and fixedly connected to the fixed sleeve 111 by inserting the first screw 103 into the screw positioning through hole 101 and the positioning threaded hole 102 in sequence.

[0042] In the above embodiments, see the attached Figure 4 , 5 Two longitudinal grooves 1121 are symmetrically arranged on the upper and lower end surfaces of the crushing plate 112. Each rack 113 is horizontally embedded in the groove 1121 and fixed by a rack seat. A bolt positioning through hole 1131 is arranged on the side of the rack seat of the rack 113.

[0044] In the above embodiment, the transmission component is a crushing valve of a TL modular combined gear reducer. The power of the crushing valve drives the crushing valve rotor blades to rotate through the TL modular combined gear reducer. The gap between the blades is 10 mm. The large and fast materials coming out of the cement storage are squeezed and crushed by the crushing valve blades. The particle size of the material out of the crushing valve is 10 mm, which can fully meet the quality requirements of cement leaving the factory.

[0045] It can be seen from the above technical solution that when in use, first, the controller controls the two electric push rods 95 to drive the two screen plates 91 to maintain a horizontal state, and then the crushing material is added to the crushing valve. When the crushing material is less than 10 mm, the crushing material can directly pass through the gap between the screen plate 91 and the crushing valve rotor blades. At this time, the motor does not need to be started or the crushing valve rotor blades are driven to rotate at a lower speed after starting to meet the operation requirements. When larger block materials fall on the screen plate 91, the screen plate 91 intercepts the large block materials to increase their gravity, and the electric push rod 95 pulls down the force sensor 94, and the force sensor 94 feeds back a signal to the controller. The controller controls the electric push rod 95 to extend its telescopic end to rotate the screen plate 91 downward to release the intercepted block materials. At the same time, the controller controls the motor to drive the crushing blades to rotate within the set speed range for crushing according to the weight of the block materials.
