[0024] The housing assembly 1 comprises a housing 101, a crushing chamber 102 is provided in the housing 101, a loading port is provided on the front of the housing 101, a partition 103 is movably inserted in the top surface of the loading port, a triangular stop plate 104 is fixedly installed at a corner of the bottom back of the partition 103, a servo motor 105 is fixedly installed at the bottom back of the housing 101, a slide groove is provided in the middle of the bottom surface of the crushing chamber 102, a threaded rotating rod 106 is rotatably installed in the slide groove, and a threaded moving plate 107 is threadedly sleeved on the rod body of the threaded rotating rod 106;

[0025] The feeding assembly 2 includes a slide plate 201, a pulley is fixedly installed at each of the four corners of the bottom end of the slide plate 201, a material box 202 is fixedly installed at the top of the slide plate 201, a movable ladder plate 203 is fixedly installed on one side of the slide plate 201, the rear part of the bottom surface of the slide plate 201 is fixedly connected to the top surface of the threaded moving plate 107, and the triangular retaining plate 104 is located directly in front of the movable ladder plate 203;

[0026] The crushing assembly 3 includes a hydraulic cylinder 301, a breaker hammer 302 is fixedly installed at the bottom end of the hydraulic rod of the hydraulic cylinder 301, and a plurality of pointed heads 303 are fixedly installed on the bottom surface of the breaker hammer 302. The breaker hammer 302 is driven to fall by the hydraulic cylinder 301 to crush the gravel in the material box 202. The plurality of pointed heads 303 are evenly distributed on the bottom surface of the breaker hammer 302, which can make it more convenient to crush the stones and improve the crushing efficiency.

[0027] In this embodiment, the hydraulic cylinder 301 is fixedly installed at the middle of the top surface of the shell 101 , the bottom end of the hydraulic rod of the hydraulic cylinder 301 extends into the crushing chamber 102 , and the water tank 401 is fixedly installed at a corner of the top surface of the shell 101 .

[0028] The dust reduction component 4 includes a water tank 401, a water pipe 402 is fixedly connected to the bottom of one side of the water tank 401, and the other end of the water pipe 402 is fixedly connected to a dust reduction spray head 403. The dust reduction spray head 403 is fixedly installed on the top of the front end surface in the crushing chamber 102. The water pump arranged in the water tank 401 can transport water to the water pipe 402, and the water in the water tank 401 can be transported to the dust reduction spray head 403 through the water pipe 402. The dust generated during the crushing can be sprayed with water mist by the dust reduction spray head 403 to perform dust reduction operation.

[0029] A material placing groove is provided on the top surface of the material placing box 202, and the top diameter of the material placing groove is larger than the bottom surface size of the breaker 302, so as to improve the structural rationality of the lifting device.

[0030] When in use, the servo motor 105 is started, and the servo motor 105 drives the threaded rotating rod 106 to rotate. Under the action of the threaded rotating rod 106, the threaded moving plate 107 can be controlled to move. The movement of the threaded moving plate 107 can drive the feeding assembly 2 to move, and the sliding plate 201 can be controlled to move outward to drive the material placement box 202 and the moving ladder plate 203 to move. Since the front side of the moving ladder plate 203 is inclined and the front side of the moving ladder plate 203 is in contact with the triangular supporting plate 104, the movement of the moving ladder plate 203 can lift the triangular supporting plate 104, and the rising of the triangular supporting plate 104 can drive the partition 103 to rise. As the material placement box 202 is extended, the partition 103 will rise synchronously. After rising to a high point, the stones to be crushed can be conveniently placed on the material placement box. The servo motor 105 rotates in the opposite direction after the feeding assembly 2 is put into the crushing chamber 102. At this time, the feeding assembly 2 will bring the crushed stones into the crushing chamber 102, and the partition 103 will also fall back under its own weight. Finally, the feeding assembly 2 will be completely retracted into the crushing chamber 102, and then the hydraulic cylinder 301 will drive the breaker 302 to fall to crush the crushed stones in the feeding box 202. The dust generated during the crushing can be sprayed with water mist by the dust reduction spray head 403 to perform dust reduction operation. Further, when the feeding assembly 2 enters the crushing chamber 102, the partition 103 will also fall synchronously. After falling, the crushing chamber 102 can be closed, thereby avoiding the safety hazard caused by the splashing of crushed stones and reducing the occurrence of dust during the crushing process.

[0031] In summary, the stone crushing device for civil engineering can control the movement of the feeding component 2 through the servo motor 105, so that the feeding component 2 can be conveniently controlled to protrude from or enter the shell 101, and then the feeding operation can be conveniently performed. At the same time, when the feeding component 2 enters the crushing chamber 102, the partition 103 will also fall down synchronously. After falling, the crushing chamber 102 can be closed, thereby avoiding the safety hazard caused by the splashing of crushed stones, and reducing the occurrence of dust generated during the crushing process, which is more practical.
