When the construction waste contacts the shield 11, the shield 11 rotates downward under the weight, so that the shield 11 of the central channel of the feeding box 9 is automatically opened, which is convenient for the construction waste to enter the crushing box 1. The construction waste is crushed by the crushing assembly without affecting the normal feeding of the construction waste. When the shield 11 loses pressure, the contracted spring 20 resets the cross plate 18 downward through the elastic force, and the cross plate 18 moves through the connecting block 17 to move the chain 14. The chain 14 moves through the sprocket 13 to make the connecting shaft 12 drive the shield 11 to reset, thereby blocking the central channel of the feeding box 9 to prevent dust from splashing or garbage fragments from jumping out.
[0028] Among them, in order to achieve the purpose of crushing construction waste, the present device adopts the following technical scheme: the crushing assembly includes two transmission shafts 3, the two transmission shafts 3 both penetrate the two side walls of the crushing box 1 and are connected to the two side walls of the crushing box 1 through bearings, the two transmission shafts 3 are fixedly provided with gears 4 at one end extending out of the crushing box 1, the two gears 4 are meshed, and the two transmission shafts 3 are fixedly sleeved with crushing rollers 5 on the outside, and a motor 2 is fixedly provided on one side of the crushing box 1, and the output end of the motor 2 is fixedly connected to one end of one of the transmission shafts 3, and the motor 2 is started, and the motor 2 rotates to drive the connected transmission shaft 3 to rotate, and the two transmission shafts 3 rotate relative to each other through the two meshing gears 4, and the two transmission shafts 3 rotate to respectively drive the two crushing rollers 5 to rotate, and the construction waste is crushed by the relatively rotating crushing rollers 5, and at the same time, the side guard plates 6 on both sides prevent the uncrushed garbage from falling out, and the crushed construction waste is screened by the filter screen 7, so that the large granular garbage is discharged from the outside of the crushing box 1 through the inclined surface of the filter screen 7, and the powdery garbage is discharged from the outside of the crushing box 1 through the inclined plate 8, so that the crushed garbage is discharged in a classified manner, which is convenient for subsequent centralized treatment;
[0029] Among them, in order to achieve the purpose of automatically opening the baffle 11 when feeding, the present device adopts the following technical solutions: the baffle 11 is arranged inside the feeding box 9 and is slidably connected to the inner wall of the feeding box 9, the chain 14 is sleeved on the outside of the sprocket 13 and the sprocket 2 15, the sprocket 13 and the sprocket 2 15 are driven and connected by the chain 14, the sprocket 2 15 is sleeved on the outside of the rotating shaft 16 and is connected to the rotating shaft 16 through bearings, the two ends of the rotating shaft 16 are respectively connected to the two side walls of the circular cavity 10 through bearings, the cross plate 18 is sleeved on the outside of the two guide pillars 19 and is slidably connected to the two guide pillars 19, the top of the guide pillar 19 is fixedly connected to the top of the circular cavity 10, the top of the spring 20 is fixedly connected to the top of the circular cavity 10, and the bottom of the spring 20 is fixedly connected to the top of the circular cavity 10. The part is fixedly connected to the top of the cross plate 18, and the material is fed into the crushing box 1 through the feeding box 9. When the construction waste contacts the shield plate 11, the shield plate 11 rotates downward under the weight, so that the shield plate 11 of the central channel of the feeding box 9 is automatically opened, which is convenient for the construction waste to enter the crushing box 1, and the construction waste is crushed by the relatively rotating crushing rollers 5 without affecting the normal feeding of the construction waste. At the same time, the shield plate 11 rotates through the connecting shaft 12 to rotate the sprocket wheel 13, and the rotation of the sprocket wheel 13 drives the chain 14 to rotate. The rotation of the chain 14 pulls the cross plate 18 upward through the connected connecting block 17.

When the construction waste contacts the shield plate 11, the shield plate 11 rotates downward under the weight, so that the shield plate 11 of the central channel of the feeding box 9 automatically opens, which is convenient for the construction waste to enter the crushing box 1. The construction waste is crushed by the relatively rotating crushing rollers 5, which does not affect the normal feeding of the construction waste. At the same time, the shield plate 11 rotates through the connecting shaft 12 to rotate the sprocket wheel 13, and the rotation of the sprocket wheel 13 drives the chain The bar 14 rotates, and the chain 14 rotates through the connected connecting block 17 to pull the cross plate 18 upward. The movement of the cross plate 18 causes the spring 20 to contract. When the shield 11 loses pressure, the contracted spring 20 uses elastic force to reset the cross plate 18 downward, and the cross plate 18 moves through the connecting block 17 to move the chain 14. The chain 14 moves through the sprocket 13 to cause the connecting shaft 12 to drive the shield 11 to reset, thereby blocking the central channel of the feeding box 9 to prevent dust from splashing or garbage fragments from jumping out. The crushed construction waste is screened by the filter screen 7, so that large granular garbage is discharged from the outside of the crushing box 1 through the inclined surface of the filter screen 7, and the powdered garbage is discharged from the outside of the crushing box 1 through the inclined plate 8, so that the crushed garbage is discharged in a classified manner, which is convenient for subsequent centralized treatment.
