[0029] See also Figure 1-3 In an embodiment of the present invention, a highway bridge construction device includes a shell 1, a symmetrical crushing roller 2 is provided on the upper part of the inner cavity of the shell 1, a sieve plate 14 is fixedly connected to the middle part of the inner cavity of the shell 1, and a receiving box 13 is slidably connected to the lower part of the inner cavity of the shell 1 for receiving fine materials passing through the sieve hole. A driving mechanism 5 for driving the crushing roller 2 to rotate is provided on one side of the upper part of the shell 1, and a symmetrical chute 6 is provided on one side of the upper part of the shell 1 close to the driving mechanism 5. A limiting member 7 for limiting and fixing the crushing roller 2 is provided in the chute 6. When the crushing roller 2 is relatively dislocated, the crushing roller 2 moves horizontally to both sides and separates from the output end of the driving mechanism 5, and the output end of the limiting member 7 limits the crushing roller 2.

[0030] See also Figure 2The driving mechanism 5 includes a driving motor 51. The lower end of the driving motor 51 is fixedly connected to the mounting platform 4. The mounting platform 4 is fixedly connected to the side wall of the shell 1. The output end of the driving motor 51 is fixedly connected to the driving gear 52. Symmetrical driven gears 53 are provided on both sides of the driving gear 52. The middle part of both ends of the crushing roller shaft 2 is fixedly connected to the rotating shaft 54. The rotating shaft 54 ​​on the side close to the driving motor 51 is fixedly connected to the driven gear 53. The driven gear 53 and the driving gear 52 are meshed with each other. When the driving motor 51 drives the driving gear 52 to rotate clockwise, the symmetrical driven gears 53 rotate clockwise and counterclockwise respectively, thereby driving the crushing roller shaft 2 to rotate through the rotating shaft 54, and then the engineering waste entering the shell 1 can be crushed.

[0031] See also Figure 3-4The limiting member 7 includes a slider 71, which is sleeved on the outer wall of the rotating shaft 54. The slider 71 is rotatably connected to the rotating shaft 54. The slider 71 is elastically connected to the inner cavity of the chute 6. When there are things that are difficult to crush, such as steel bars, in the engineering waste entering the shell 1, in order to avoid the crushing roller 2 from being stuck because it cannot crush the steel bars, the crushing rollers 2 will move away from each other to avoid being stuck by the steel bars. After the crushing rollers 2 move horizontally to both sides, the motor is still driving the driving gear 52 to rotate and the steel bars may not have completely fallen below the level of the lower end of the crushing roller 2. The lengths of the steel bars are different. If the crushing rollers 2 are not limited after separation but are directly reset due to elastic force, the driving gear 52 and the driven gear 53 may not be able to mesh and collide with each other, causing damage. If the steel bar is long, the crushing roller 2 may come into contact with the steel bar again, resulting in repeated horizontal movement of the roller, which in turn causes excessive wear on the teeth of the crushing roller 2. A round rack 72 is fixedly connected to the middle of one side of the upper part of the slider 71. The round rack 72 is slidably connected to the shell 1, and a ratchet is rotatably connected to the side of the upper part of the inner cavity of the chute 6 away from the rotating shaft 54. The ratchet 73 is rotated by the gear 72 and the gear 73 is rotated by the gear 72. The gear 73 is rotated by the gear 72 and the gear 73 is rotated by the gear 72. The ratchet 73 is rotated by the gear 72 and the gear 73 is rotated by the gear 72. The ratchet 73 is rotated by the gear 72 and the gear 73 is rotated by the gear 72. After the block 71 stops moving, the elastic force will push the slider 71 close to the driving gear 52. Since the block 76 limits the counterclockwise rotation of the ratchet 73, the slider 71 will not be pushed by the elastic force, thereby avoiding the collision between the driving gear 52 and the driven gear 53. After the crushing roller 2 is separated, since it will not reset automatically, the crushing roller 2 will gradually stop. At this time, there is enough time to turn off the drive motor 51, and then press the push rod 75 to separate the block 76 from the ratchet 73, thereby losing the limit on the ratchet 73, thereby resetting the crushing roller 2 and the driven gear 53.

[0032] After the crushing roller 2 is separated, although it can avoid being stuck by the steel bars, if the steel bars fall in a vertical state after the crushing roller 2 is separated, the steel bars may be inserted into the sieve holes opened on the sieve plate 14, causing the steel bars to be stuck in the sieve holes and difficult to remove, thereby affecting the operation of the device. Therefore, an adjustment mechanism 17 is provided on the sieve plate 14 to prevent the steel bars from falling into the sieve holes. In order to make the output end of the adjustment mechanism 17 block the sieve holes only when the crushing rollers 2 are away from each other, a symmetrical follower is provided between the adjustment mechanism 17 and the slider 71 to drive the adjustment mechanism 17, so as to avoid affecting the normal process of crushing waste.

[0033] See also Figure 5-6 The driven member includes a driven rod 8, which is slidably connected to the side wall of the housing 1. The driven rod 8 is an L-shaped rod, consisting of a horizontal rod and a vertical rod. The upper end of the vertical rod is fixedly connected to the lower end of the slider 71. A horizontal groove is provided in the middle of the upper end of the horizontal rod. The horizontal groove passes through the horizontal rod. The side of the horizontal groove away from the vertical rod is fixedly connected to the round rod. A driven plate 9 is provided on the side of the horizontal rod away from the vertical rod. The driven plate 9 is vertically slidably connected to the side wall of the housing 1. The width of the horizontal groove is greater than the width of the driven plate 9. A driving groove 10 is provided on the upper part of the driven plate 9. The driving groove 10 consists of a horizontal groove box and an oblique groove. The oblique groove is toward the driving gear 52. The round rod is slidably connected to the inclined groove, that is, when the vertical rod moves with the slider 71, the round rod will drive the driven plate 9 to move downward through the inclined groove. As the slider 71 continues to move, the round rod will move from the inclined groove to the transverse groove. After entering the transverse groove, the round rod will no longer push the driven plate 9 to move downward, but will limit the movement of the driven plate 9 in the vertical direction, thereby keeping the driven plate 9 stable. A groove is provided at the lower end of the driven plate 9, and a symmetrical guide groove 11 is provided on the side wall of the groove. The guide groove 11 is a groove facing the direction of the driving gear 52 and inclined upward, and a card slot 12 is provided at both ends of the guide groove 11.

[0034] See also Figure 7-10The adjusting mechanism 17 includes a plurality of first rotating rods 175 and a second rotating rod 176. The first rotating rod 175 and the second rotating rod 176 are both rotatably connected to the sieve plate 14. The outer walls of the first rotating rod 175 and the second rotating rod 176 are fixedly connected to a plurality of baffles 177. The baffles 177 are semicircular and the number of the baffles 177 corresponds to the sieve holes. The end of the second rotating rod 176 close to the driving gear 52 is closer to the driving gear 52 than the first rotating rod 175. The ends of the first rotating rod 175 and the second rotating rod 176 close to the driving gear 52 are fixedly connected. There is an incomplete gear 171, and an annular groove is provided on the outer wall of the second rotating rod 176. The position of the annular groove corresponds to the incomplete gear 171 connected to the end of the first rotating rod 175, so as to avoid the second rotating rod 176 from hindering the rotation of the first rotating rod 175. A driven rack 172 is provided under the incomplete gear 171. The lower end of the driven rack 172 is fixedly connected to a moving rod 173. The moving rod 173 is slidably connected to the inner cavity of the sieve plate 14. The end of the moving rod 173 close to the driven plate 9 is fixedly connected to the guide rod 174. When the driven rack 172 is driven, the guide rod 174 is fixed to the inner cavity of the sieve plate 14. When the moving plate 9 does not move downward, the guide rod 174 is slidably connected to the slot 12 located below. When the driven plate 9 moves downward, the guide rod 174 enters the guide groove 11 from the slot 12, thereby causing the moving rod 173 to move in the direction away from the driven plate 9. When the round rod moves to the horizontal groove, that is, the driven plate 9 does not move downward, the guide rod 174 passes through the guide groove 11 and moves to the slot 12 located above. During the movement of the moving plate, the driven rack 172 drives the incomplete gear 171 to rotate, thereby driving the rotating rod to rotate. The baffle 177 moves, thereby driving the baffle 177 to rotate 90 degrees, so that the baffle 177 rotates from the lower part of the sieve hole cavity to a position that coincides with the upper end surface of the sieve hole, thereby blocking the sieve hole, thereby preventing the steel bar from getting stuck in the sieve hole when it falls, and the guide rod 174 is located in the card slot 12, which can limit the movement state of the moving rod 173, so that the baffle 177 will not change its position state after being hit, and in normal use, the baffle 177 is located below the sieve hole cavity and will not be directly hit by waste materials, so its service life can be guaranteed.

[0035] An electric telescopic push rod 3 is provided below the mounting platform 4. The electric telescopic push rod 3 is fixedly connected to the side wall of the shell 1. The output end of the electric telescopic push rod 3 passes through the side wall of the shell 1 and is fixedly connected to the receiving box 13. The upper end of the receiving box 13 is fixedly connected with a symmetrical connecting plate 16. The upper end of the connecting plate 16 passes through the upper end surface of the sieve plate 14 and is fixedly connected with a push plate 15. The lower part of the sieve plate 14 is slidably connected with a number of symmetrical moving blocks 18. The number of moving blocks 18 corresponds to the sum of the number of the first rotating rod 175 and the second rotating rod 176. The plane where the lower end of the moving block 18 is located exceeds the lower end of the sieve plate 14. On the same plane, the moving blocks 18 are fixedly connected with a connecting rod 19, and both ends of the connecting rod 19 are fixedly connected with the symmetrical connecting plates 16 respectively. That is, when the waste is crushed or steel bars enter the shell 1, the receiving box 13 is pushed by the electric telescopic push rod 3 to drive the push plate 15 and the moving block 18 to move horizontally, so that the crushed waste can be removed from the shell 1, or the large pieces of waste or steel bars that are not completely crushed and remain on the screen plate 14 can be automatically removed from the shell 1 without manual operation, and the moving block can squeeze out some waste stuck in the sieve holes.
