[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] like Figures 1-6As shown, the present embodiment provides a stone crusher for civil engineering, comprising a frame 1, a crushing chamber 2, a hammering component 3, a box body 4, an upper half box 41, a lower half box 42 and a rotating shaft 5. The box body 4 is connected to the upper side of the frame 1, and the box body 4 is obliquely divided into an upper half box 41 and a lower half box 42. The crushing chamber 2 is connected to the lower half box 42, the hammering component 3 is connected to the upper half box 41, and the rotating shaft 5 is connected to the lower side of the upper half box 41. The upper half box 41 is rotatably connected to the frame 1 via the rotating shaft 5, and the upper half box 41 is separated from the lower half box 42 after rotation.

[0021] In the above embodiment, the crusher housing 4 is tilted and divided into two sub-housings 4, namely, an upper half housing 41 and a lower half housing 42. When the crushing chamber 2 and the hammer component 3 need to be replaced or repaired, the upper half housing 41 is separated from the lower half housing 42, and the upper half housing 41 is rotated to fully expose the interior of the housing 4. The crushing chamber 2 or the hammer component 3 can be replaced and repaired respectively. The operation is convenient, the maintenance field is sufficient, and the disassembly and assembly of the components are convenient.

[0022] The upper half box 41 and the lower half box 42 can be connected by bolts, quick locks and other clear existing technologies.

[0023] Specifically, it also includes a supporting frame 6, a gear 7 and a rack 8. The supporting frame 6 is slidably connected to one side of the frame 1. The supporting frame 6 is arranged close to the upper half box 41. Gears 7 are connected to both ends of the rotating shaft 5. Racks 8 are fixedly connected to both sides of the supporting frame 6, and the racks 8 are correspondingly meshed with the gears 7.

[0024] In the above embodiment, the rotation of the rotating shaft 5 is linked with the movement of the supporting frame 6. When the rotating shaft 5 and the upper half box 41 are rotated and opened, the rotating shaft 5 drives the gear 7, and the gear 7 drives the rack 8, so that the supporting frame 6 moves on the frame 1. The supporting frame 6 extends out, plays a balancing role of the device, and facilitates maintenance and replacement operations.

[0025] Specifically, it also includes a roller group 9 and a guide rail 10 . The roller groups 9 are connected to both sides of the upper side of the support frame 6 , and the guide rails 10 are connected to both sides of the frame 1 . The roller groups 9 roll on the corresponding guide rails 10 .

[0026] In the above embodiments, the arrangement of the roller assembly 9 and the guide rail 10 improves the stability of the supporting frame 6 .

[0027] Specifically, it also includes a spring rod 11. Both sides of the side wall of the upper half box 41 are connected with a spring rod 11, and the spring rod 11 cooperates with the supporting frame 6.

[0028] In the above embodiment, after the upper half box 41 rotates 90 degrees, the spring rod 11 abuts against the supporting frame 6 to provide buffering and supporting effects for the upper half box 41 .

[0029] Specifically, it also includes a rotary cylinder 12 and a sealing plate 13. The rotary cylinder 12 is connected to the frame 1, the output shaft of the rotary cylinder 12 is fixedly connected to the rotating shaft 5, and a sealing plate 13 is provided at the connection between the upper half box 41 and the lower half box 42.

[0030] In the above embodiment, the rotary cylinder 12 drives the rotating shaft 5 to rotate, and the sealing plate 13 has a sealing effect to prevent dust from escaping from the gap during crushing. The sealing plate 13 is made of a multi-layer composite material and can adopt existing technology.

[0031] The working principle of the present invention is as follows: when maintenance or replacement is needed, the rotary cylinder 12 is operated to drive the rotating shaft 5 to rotate, and the rotating shaft 5 drives the upper half box 41 to rotate 90 degrees. During this process, the rotating shaft 5 drives the gear 7, and the gear 7 drives the rack 8, so that the support frame 6 moves out, and the roller group 9 rolls on the corresponding guide rail 10. After the upper half box 41 rotates 90 degrees, the support frame 6 is fully extended, and the spring rods 11 on both sides abut against the support frame 6. After that, the interior of the fully opened box 4 can be replaced and repaired.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
