[0024] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0025] Please see Figures 1-4 This utility model provides an aggregate crushing device for preparing steel fiber reinforced concrete pipe segments, comprising a housing 100. A fixed crushing roller 101 and an adjustable crushing roller 102 are rotatably mounted inside the housing 100. Rotating shafts B106 are connected to both sides of the fixed crushing roller 101, with the ends of the rotating shafts B106 extending to the outside of the housing 100. Sliding grooves 103 are provided on both sides of the housing 100 along its length, with sliding blocks 104 slidably mounted inside the grooves 103. Rotating shafts A105 are connected to both sides of the adjustable crushing roller 102, with the ends of the rotating shafts A105 extending to the outside of the sliding blocks 104. Transmission mechanisms 200 capable of simultaneously driving the rotating shafts A105 and B106 to rotate are provided on both sides of the housing 100 along its length. A drive mechanism 300 cooperating with the two sets of transmission mechanisms 200 is provided on one side of the housing 100 along its width. An adjustment mechanism 400 is provided on the other side of the housing 100 in the width direction, which is capable of adjusting the distance between the adjusting crushing roller 102 and the fixed crushing roller 101.

[0026] In use, the transmission mechanism 200 and the drive mechanism 300 work together to drive the rotating shafts B106 on both sides of the fixed crushing roller 101 and the rotating shafts A105 on both sides of the adjusting crushing roller 102 to rotate. This causes the fixed crushing roller 101 and the adjusting crushing roller 102 to rotate in opposite directions simultaneously, thus achieving the purpose of crushing aggregates. Since both ends of the fixed crushing roller 101 and the adjusting crushing roller 102 are subjected to the same force, a greater torque can be provided, and the force during the crushing process can be balanced, reducing vibration and noise caused by uneven force, which helps to extend the service life of the device. Furthermore, the distance between the adjusting crushing roller 102 and the fixed crushing roller 101 can be adjusted by the adjusting mechanism 400, thereby adjusting the crushed particle size of the aggregates to meet different application scenarios and customer needs, offering high flexibility.

[0027] Preferably, the transmission mechanism 200 includes a bearing seat 201 mounted on the outer surface of the housing 100. A transmission shaft A202 is rotatably mounted through the bearing seat 201. The end of the transmission shaft A202 is connected to a transmission shaft B203 via a connecting mechanism 500. A worm gear A204 is mounted on the outer surface of both the transmission shaft A202 and the transmission shaft B203. A worm wheel A205 is mounted on the end of both the rotating shaft A105 and the rotating shaft B106. The worm wheel A205 is meshed with the worm gear A204.

[0028] When the drive mechanism 300 drives the transmission shaft A202 to rotate, it drives the transmission shaft B203 to rotate synchronously through the connecting mechanism 500, which in turn drives the two worm gears A204 to rotate. Since the worm gears A204 and worm wheels A205 mesh with each other, the purpose of driving the rotating shafts B106 and A105 to rotate simultaneously can be achieved. Furthermore, by setting the worm gears A204 and worm wheels A205, the transmission ratio can be increased, thereby improving the torque of the fixed crushing roller 101 and the adjustable crushing roller 102.

[0029] Preferably, the drive mechanism 300 includes a dual-axis motor 301 mounted on the outer surface of the housing 100. The ends of the two output shafts of the dual-axis motor 301 are connected to a drive shaft C302. A worm gear B303 is mounted on the end of the drive shaft C302. A worm wheel B304 is mounted on the end of the drive shaft A202 opposite to the drive shaft B203. The worm wheel B304 is meshed with the worm gear B303.

[0030] When the dual-axis motor 301 is started, its two output shafts drive the two transmission shafts C302 to rotate respectively. The transmission shafts C302 drive the worm B303 to rotate. Since the worm B303 and the worm wheel B304 mesh with each other, they can drive the two transmission shafts A202 to rotate simultaneously, thus achieving transmission coordination. Furthermore, by setting the worm B303 and the worm wheel B304, the transmission ratio can be further increased, and the torque of the fixed crushing roller 101 and the adjustable crushing roller 102 can be further improved.

[0031] Preferably, the adjusting mechanism 400 includes a horizontal plate 401 disposed on the outside of the housing 100, a screw 403 rotatably connected to the outer surface of the housing 100, the end of the screw 403 passing through the interior of the horizontal plate 401 and threadedly connected thereto, and connecting shafts 402 connected to both sides of the horizontal plate 401, the ends of the connecting shafts 402 being rotatably connected to the transmission shaft B203.

[0032] When it is necessary to adjust the distance between the adjusting crushing roller 102 and the fixed crushing roller 101, the screw 403 can be turned to move the horizontal plate 401 closer to or further away from the housing 100, which in turn drives the transmission shaft B203 to move through the connecting shaft 402, and drives the worm gear A204 and worm wheel A205 to move synchronously, thereby adjusting the position of the adjusting crushing roller 102.

[0033] Preferably, the connecting mechanism 500 includes a fixed plate A501 installed at the end of the drive shaft A202, and the fixed plate B502 is installed at the end of the drive shaft B203. A plurality of insert rods 503 are connected to the outer surface of the fixed plate A501, and the insert rods 503 extend to the other side of the fixed plate B502.

[0034] By setting up fixed plate A501, fixed plate B502 and insert rod 503, the drive shaft A202 can drive the drive shaft B203 to rotate when it rotates, and the drive shaft A202 and drive shaft B203 have extensibility, which can adapt to the adjustment of the position of the crushing roller 102 and transmit torque normally.

[0035] Preferably, a turntable 600 is mounted on the end of the screw 403.

[0036] The turntable 600 facilitates the rotation of the screw 403.

[0037] Preferably, the outer surface of the housing 100 is provided with a plurality of screw holes 700 coaxially around the screw 403, and a fixing block 701 is installed on the outer surface of the screw 403. The fixing block 701 is fitted with bolts 702 that match the screw holes 700.

[0038] After adjusting the position of the adjusting crushing roller 102 by rotating the screw 403, the bolt 702 can be screwed into the screw hole 700 corresponding to its current position, thus locking the screw 403 and preventing it from loosening and reversing.

[0039] Preferably, a bearing A800 is mounted on the outer surface of the rotating shaft A105, and a bearing B801 is mounted on the outer surface of the drive shaft B203. The bearing A800 and the bearing B801 are connected by a connecting rod 802.

[0040] By using bearings A800 and B801 and connecting rod 802, it can be ensured that worm A204 and worm wheel A205 are always in a meshed state, preventing them from disengaging.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
