[0018] Please see Figure 1-3 ,

[0019] Example 1: A civil engineering construction waste treatment device includes a base plate 1, a crushing box 2 is fixedly installed on the upper surface of the base plate 1, a feed inlet is opened at the top of the crushing box 2, a discharge outlet is opened on the side of the crushing box 2, and two crushing rollers 17 are rotatably connected between the two inner side walls of the crushing box 2.

[0020] A screw 3 is rotatably connected to the upper surface of the base plate 1. A screw sleeve 4 is threaded onto the surface of the screw 3. A slide rod 5 is fixedly connected to the upper surface of the base plate 1. A slide sleeve 6 is slidably fitted onto the surface of the slide rod 5. A connecting plate 7 is fixedly connected between the slide sleeve 6 and the screw sleeve 4. A short plate 8 is fixedly connected to the upper surface of the connecting plate 7. Two electric push rods 9 are fixedly installed on the side of the short plate 8. The output ends of the two electric push rods 9 extend to the other side of the short plate 8 and are fixedly connected to a horizontal plate 10. A material storage assembly is provided on the horizontal plate 10.

[0021] Example 2: The difference between this example and Example 1 is that the storage assembly includes a storage box 11. Two short plates are fixedly connected to the upper surface of the horizontal plate 10. One end of the storage box 11 is rotatably installed between the two short plates. A groove is provided on the upper surface of the horizontal plate 10. A lead screw 12 is rotatably connected between the two inner side walls of the horizontal plate 10. A lead screw sleeve 13 is threaded onto the surface of the lead screw 12. A limiting rod 14 is fixedly connected between the two inner side walls of the horizontal plate 10. A limiting sleeve 15 is slidably fitted onto the surface of the limiting rod 14. A connecting rod 16 is movably connected between the limiting sleeve 15 and the lead screw sleeve 13 and the lower surface of the storage box 11. A long rod is fixedly connected between the lead screw sleeve 13 and the limiting sleeve 15, which facilitates the storage of construction waste and makes it easier to subsequently put the construction waste into the crushing box 2.

[0022] Example 3: The difference between this example and Example 1 is that a first motor 18 is fixedly connected to the side of the horizontal plate 10. The output end of the first motor 18 passes through the connected horizontal plate 10 and is fixedly connected to one end of the lead screw 12. The rotation of the first motor 18 drives the storage box 11 to tilt, and the construction waste stored inside is poured into the crushing box 2.

[0023] Example 4: The difference between this example and Example 1 is that the upper surface of the connecting plate 7 has two sliding grooves 19, and the sliding grooves 19 are slidably connected to the sliding blocks 20. The two sliding blocks 20 are fixedly connected to the horizontal plate 10, so that the movement of the horizontal plate 10 is more stable and smooth.

[0024] Example 5: The difference between this example and Example 1 is that a second motor 21 is fixedly connected to the side of the crushing box 2. The output end of the second motor 21 extends into the interior of the crushing box 2 and is fixedly connected to one end of one of the crushing rollers 17. The other ends of both crushing rollers 17 extend to the outside of the crushing box 2 and are fixedly connected to gears 22. The two gears 22 mesh with each other. The rotation of the second motor 21 can drive the two crushing rollers 17 to quickly crush the construction waste.

[0025] Example 6: The difference between this example and Example 1 is that the top of the slide bar 5 is fixedly connected to a long plate 23, the screw 3 is rotatably connected to the long plate 23, the upper surface of the long plate 23 is fixedly connected to a third motor 24, the output end of the third motor 24 passes through the connected long plate 23 and is fixedly connected to the screw 3. The rotation of the third motor 24 can automatically lift the construction waste to the feed port of the crushing box 2, saving time and effort.

[0026] In summary, this civil engineering construction waste treatment device, when in use, involves placing the construction waste to be processed into the storage bin 11. Then, the rotation of the third motor 24 drives the screw 3 to rotate, thereby moving the screw sleeve 4 and connecting plate 7 upwards, and also moving the horizontal plate 10 and storage assembly upwards. When the horizontal plate 10 and storage bin 14 move above the crushing chamber 2, the extension of the electric push rod 9 moves the storage bin 11 forward to the upper feed inlet position of the crushing chamber 2. Then, the rotation of the first motor 18 drives the screw... The rotation of rod 12 causes the lead screw sleeve 13 and the limiting sleeve 15 to move, and through the action of connecting rod 16, it lifts one end of storage box 11, causing the construction waste inside storage box 11 to be poured into the crushing box 2. At the same time, the rotation of the second motor 21 drives the two crushing rollers 17 to quickly crush the construction waste. It is convenient and fast. When in use, the device can automatically lift and pour the construction waste into the crushing box 2 for crushing and processing, without the need for manual handling and lifting, saving time and effort and improving processing efficiency.
