[0027] Example 1, as Figure 1 shown, a stone crushing device for municipal construction, including a crushing box 1, two crushing rollers 3 are rotatably connected in the crushing box 1, spur gears 4 are fixedly connected to both of the two crushing rollers 3, the two spur gears 4 mesh with each other, a first motor 2 is fixedly connected to the crushing box 1, and the output shaft of the first motor 2 is fixedly connected to one of the crushing rollers 3.

[0028] Refer to Figures 2 to 4, a crushing structure 5 is provided on the crushing box 1. The crushing structure 5 is mainly composed of a sieve plate 51. The sieve plate 51 is arranged in the crushing box 1. An outlet 52 is provided on one side of the crushing box 1. The stone material is put between the two crushing rollers 3. The first motor 2 is started. The output shaft of the first motor 2 drives one crushing roller 3 to rotate, and then drives a spur gear 4 to rotate, so that the two spur gears 4 rotate in opposite directions, and further the two crushing rollers 3 rotate in opposite directions to crush the stone material. The crushed stone material enters the crushing box 1 and falls on the sieve plate 51. The stone material that meets the requirements falls through the sieve holes on the sieve plate 51, and the stone material that does not meet the requirements remains on the sieve plate 51 and slides out of the crushing box 1 along the sieve plate 51 through the outlet 52 under the action of gravity, without the need for staff to re-sort, thus avoiding the situation that due to these large-volume crushed stone materials not meeting the production use standards, the staff need to re-sort and screen out the large-volume crushed stone materials from the crushed stone materials, and then perform crushing treatment again, which increases the labor volume and working time of the staff and reduces the stone crushing efficiency. A crushing disk 53 is fixedly connected to one side of the crushing box 1. A rectangular rod 54 is fixedly connected to the crushing box 1. A second motor 55 is fixedly connected to the rectangular rod 54. A rotating plate 56 is fixedly connected to the output shaft of the second motor 55. A sliding rod 58 is arranged on the rotating plate 56. A rolling socket ball 59 is arranged below the sliding rod 58. The second motor 55 is started. The output shaft of the second motor 55 drives the sliding rod 58 to rotate, and then drives the rolling socket ball 59 to do circular motion in the crushing disk 53. The rolling socket ball 59 continuously rolls and crushes the stone material, and can perform secondary crushing on the stone material, thereby improving the utilization rate of the stone material. A material receiving device can be arranged below the sieve plate 51 and below the crushing disk 53 to collect the crushed stone material. A sliding groove 57 is opened on the rotating plate 56. The sliding groove 57 is slidably connected to the sliding rod 58. The sliding rod 58 can be slid back and forth, so as to change the rotation radius of the rolling socket ball 59 and make the rolling crushing more comprehensive. A reciprocating lead screw 510 is rotatably connected in the sliding groove 57. A third motor 511 is fixedly connected to the rotating plate 56. One end of the third motor 511 is fixedly connected to the reciprocating lead screw 510. The third motor 511 is started. The output shaft of the third motor 511 drives the reciprocating lead screw 510 to rotate. Since there are two sections of thread grooves with opposite directions on the reciprocating lead screw 510 and the two ends are connected by a transition curve, and there are components in the sliding rod 58 that slide with the thread grooves on the reciprocating lead screw 510, rotating the reciprocating lead screw 510 can drive the sliding rod 58 to reciprocate, making the reciprocating operation more convenient. A guide plate 512 is fixedly connected to one side of the crushing box 1. Two baffle plates 513 are fixedly connected to the guide plate 512. The guide plate 512 can guide the stone material, and the two baffle plates 513 can prevent the stone material from sliding off both sides of the guide plate 512 and causing waste.

[0029] Refer to Figure 1, a reciprocating structure 6 is provided on the crushing box 1. The reciprocating structure 6 mainly consists of four chutes 61. The four chutes 61 are respectively arranged in pairs on both sides of the crushing box 1. A slider 62 is slidably connected in the chute 61. The slider 62 is fixedly connected to the sieve plate 51. The slider 62 can be slid up and down to drive the sieve plate 51 to slide up and down, so that the uncompletely crushed stones on the sieve plate 51 slide down into the crushing disc 53, improving the crushing efficiency. A rack 63 is fixedly connected to one slider 62. A half gear 64 is meshed with the rack 63. When the half gear 64 is meshed with the rack 63, rotating the half gear 64 will drive the rack 63 to slide upward. When it rotates to the smooth surface of the half gear 64 contacting the rack 63, the half gear 64 will slide downward under the action of gravity. Repeating this way can improve the screening effect. A fourth motor 65 is fixedly connected to the crushing box 1. The output shaft of the fourth motor 65 is fixedly connected to the half gear 64. Starting the fourth motor 65, the output shaft of the fourth motor 65 drives the half gear 64 to rotate, making the operation more convenient.

[0030] Working principle: Put the stone between two crushing rollers 3. Start the first motor 2. The output shaft of the first motor 2 drives one crushing roller 3 to rotate, and then drives a spur gear 4 to rotate, causing the two spur gears 4 to rotate in opposite directions. Further, the two crushing rollers 3 rotate in opposite directions to crush the stone. The crushed stone enters the crushing box 1 and falls on the sieve plate 51. The stones that meet the requirements fall through the sieve holes on the sieve plate 51, and the stones that do not meet the requirements remain on the sieve plate 51 and slide out of the crushing box 1 along the sieve plate 51 through the discharge port 52 under the action of gravity, without the need for workers to re-sort. Thus, it avoids the situation where large-sized crushed stones do not meet the production use standards, and workers need to re-sort and screen out the large-sized crushed stones from the crushed stones, and then perform crushing treatment again, which increases the labor amount and working time of the workers and reduces the stone crushing efficiency. Start the second motor 55. The output shaft of the second motor 55 drives the sliding rod 58 to rotate, and then drives the rolling socket ball 59 to move in a circular motion in the crushing disc 53. The rolling socket ball 59 continuously rolls and crushes the stone, which can perform secondary crushing on the stone, thereby improving the utilization rate of the stone. A material receiving device can be set below the sieve plate 51 and below the crushing disc 53 to collect the crushed stone. The sliding rod 58 can be slid back and forth, thereby changing the rotation radius of the rolling socket ball 59 to make the rolling crushing more comprehensive. Start the third motor 511. The output shaft of the third motor 511 drives the reciprocating lead screw 510 to rotate. Since there are two threads with opposite directions on the reciprocating lead screw 510 and the two ends are connected by a transition curve, and there are components in the sliding rod 58 that slide with the thread grooves on the reciprocating lead screw 510, rotating the reciprocating lead screw 510 can drive the sliding rod 58 to reciprocate, making the reciprocating operation more convenient. The guide plate 512 can guide the stone, and the two baffle plates 513 can prevent the stone from sliding off both sides of the guide plate 512 and causing waste. The slider 62 can be slid up and down to drive the sieve plate 51 to slide up and down, so that the stones that are not completely crushed on the sieve plate 51 slide into the crushing disc 53, improving the crushing efficiency. When the half gear 64 meshes with the rack 63, rotate the half gear 64, and the half gear 64 will drive the rack 63 to slide upward. When it rotates until the smooth surface of the half gear 64 contacts the rack 63, the half gear 64 will slide downward under the action of gravity. Repeating this process can improve the screening effect. Start the fourth motor 65. The output shaft of the fourth motor 65 drives the half gear 64 to rotate, making the operation more convenient.
