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.

[0019] The rotational connection described in this device refers to the process of baking the bearing on the shaft, providing a spring retaining ring groove on the shaft or the shaft hole, and clamping the elastic retaining ring in the retaining ring groove to achieve axial fixation of the bearing and realize rotation; the articulation refers to a connection method that is active on connecting parts such as hinges, pins and short shafts.

[0020] The present invention will be described in detail below with reference to the accompanying drawings. Example

[0021] The following is combined with Figure 1-4Description of the present embodiment A crusher for clean production of cement clinker, comprising: a crushing box 1, a feed port is provided on the side wall of the crushing box 1, a baffle 2 is hinged on the upper part of the feed port, the baffle 2 is made of hard plastic, the baffle 2 can completely cover the feed port and can only rotate inward, an oblique guide plate 3 is connected to the side wall of the crushing box 1 outside the feed port, a crushing mechanism 4 is provided in the crushing box 1, and a discharge mechanism 5 is provided at the bottom of the crushing box 1;

[0022] When in use, cooked stones and other clinker are directly put into the oblique guide plate 3 by a forklift, and the clinker falls into the feed port along the inclined surface of the oblique guide plate 3. The baffle 2 rotates inward around the hinge axis to open, and the baffle 2 automatically resets after the feeding is completed, and no dust is generated. When the crushing mechanism 4 is crushing, the baffle 2 remains closed, and dust does not overflow, thereby protecting the environment and the health of workers.

[0023] The crushing mechanism 4 includes a connecting shaft 41, which is rotatably connected to a bearing seat 42, a bevel gear 1 43 is connected to the lower end of the connecting shaft 41, and the two sides of the bevel gear 1 43 are respectively meshed with two bevel gears 2 44, and the two bevel gears 2 44 are respectively connected to a crushing shaft 45 and a bearing sleeve 46, and the crushing shaft 45 is rotatably connected to the bearing sleeve 46, and the side walls at both ends of the crushing box 1 are rotatably connected to the bearing sleeve 46, and a hammer frame 47 is connected between the two bearing sleeves 46, and the hammer frame 47 is composed of a plurality of shafts uniformly distributed around the circumference, and hammer heads are connected to the crushing shaft 45 and the hammer frame 47 shafts, and the bottom wall of the crushing box 1 is semicircular, and the maximum rotation range of the hammer head of the hammer frame 47 coincides with the inner bottom wall of the crushing box 1;

[0024] During crushing, the power of the crushing shaft 45 or the connecting shaft 41 is turned on, and the power is transmitted through the bevel gear one and the two bevel gears two 44, so that the crushing shaft 45 and the bearing sleeve 46 rotate in opposite directions relative to each other, the bearing sleeve 46 drives the hammer frame 47 to rotate, the hammer frame 47 drives the hammer head to rotate, the crushing shaft 45 drives the hammer head and the hammer head of the hammer frame 47 to rotate in opposite directions relative to each other, and the two groups of hammer heads, one inside and one outside, rotate in opposite directions relative to each other, without dead angles, and a shear force is applied to the clinker. Under the dual crushing effects of front crushing and side shearing, the clinker crushing is completed faster and better.

[0025] The hammer head includes a hammer head 1 48 and a hammer head 2 49. The hammer head 1 48 is evenly rotatably connected to the shaft of the hammer frame 47. A hammer head 2 49 is arranged between adjacent hammer heads 1 48. The hammer head 2 49 is connected to the crushing shaft 45.

[0026] The hinged hammer head 48 can reduce the torsional force on the hammer frame 47 shaft and reduce the burden on the hammer frame 47.
