[0002] Construction waste refers to the slag, abandoned soil, abandoned materials, silt and other wastes generated during the construction, laying, demolition and repair of various buildings, structures, pipelines, etc. by construction units or individuals. When processing such waste, crushing equipment is often required to reduce it to a small amount to facilitate subsequent recycling or other processing work. Therefore, this application proposes a new type of construction waste crushing device.

The contact between the crushed object and the crushing mechanism is not tight, resulting in insufficient crushing efficiency of the garbage, which in turn affects the practicability of the crushing work of the device.

[0023] See also Figures 1 to 4 , a construction waste crushing device;

[0024] It comprises a crushing box 1, a connecting box 2 is fixedly installed at the bottom of the crushing box 1, an output box 3 is fixedly installed at the bottom of the connecting box 2, support frames 4 are fixedly installed on both sides of the top of the crushing box 1, a driving seat 5 is fixedly installed on the top of the support frame 4, a driving power source 6 is fixedly installed on the inner wall of the driving seat 5, an electric push rod 7 is electrically installed at the bottom of the driving power source 6, a contact plate 8 is fixedly installed at the bottom of the electric push rod 7, two groups of driving motors 9 are fixedly installed on one side of the crushing box 1, a crushing wheel 10 is fixedly installed at the output end of the driving motor 9, and the crushing wheel 10 is rotatably connected to the inner wall of the crushing box 1, an inclined feed plate 11 is fixedly installed at the front end and the rear end of the top of the crushing box 1, a plurality of groups of electric push rods 7 are fixedly installed inside the driving seat 5, and the contact plate 8 is in the shape of a long strip, the bottom of the contact plate 8 is in the shape of a pointed cone, and the contact plate 8 corresponds to the top of the two groups of crushing wheels 10.

[0025] When the device is used for crushing construction waste, the construction waste to be crushed is poured into the device by means of the inclined feed plate 11, so that the construction waste slides to the opening at the top of the crushing box 1, and then the driving motor 9 is powered on, and its output end can drive the rotation of the crushing wheel 10, so that the sliding construction materials can be crushed. The crushed construction materials fall into the connecting box 2 and are output through the output box 3. When the top of the device is pouring materials, the setting of the inclined feed plate 11 can assist in the crushing of the construction materials and play a proper blocking role. When the crushing wheel 10 is rotating and crushing, the driving power supply 6 in the driving seat 5 can drive the electric push rod 7 to be powered on. When the electric push rod 7 is telescopic, it can push the contact plate 8, thereby indirectly pushing the movement of the contact plate 8, which can squeeze the detected materials that slide to the bottom of the crushing box 1, assist it in crushing, reduce the accidental sliding of materials when the materials are crowded and piled up, and accelerate its crushing efficiency by squeezing.

[0026] A ventilation seat 12 is fixedly installed on one side of the connection box 2, and a fan assembly 13 is fixedly installed on the front end and the rear end of the inner wall of the ventilation seat 12. Metal meshes 14 are embedded and installed on the inner walls of both sides of the connection box 2. Multiple groups of air outlet pipes 15 are fixedly installed on the other side of the connection box 2;

[0027] By energizing the fan assembly 13 in the ventilation seat 12, the wind force generated by its operation can drive the circulation of air in the connection box 2, and then discharge the fine dust carried by the crushed building materials. The metal mesh 14 can hinder the crushed objects, and the induced odor can be transported to the external processing equipment through the exhaust pipe 15.

[0028] The two sides of the output box 3 are fixedly installed with counterweight blocks 16, the inner bottom wall of the output box 3 is fixedly installed with an inclined material plate 17, and the outer surface of the inclined material plate 17 is provided with a micro-magnetic suction plate 21;

[0029] By setting the counterweight block 16, the stability of the output box 3 and the overall placement of the device can be increased. When the inclined material plate 17 assists in the discharge of materials after crushing, the micro-magnetic suction plate 21 can have a certain magnetic attraction effect on the metal materials in the sliding material, and have a certain resistance effect on its falling work, slowing down its falling rate and ensuring its stable discharge work.

[0030] The front and back of the crushing box 1 are both fitted with thickened plates 18, the inner wall of the crushing box 1 is fixedly mounted with an arc baffle 19, and the arc baffle 19 is attached to the outside of the crushing wheel 10, and the bottom of the support frame 4 is fixedly mounted with a retaining frame 20, and the retaining frame 20 surrounds the outer surface of the electric push rod 7;

[0031] The thickened plate 18 can reduce the impact of material splashing on the inner wall of the crushing box 1 during the crushing process. The arc baffle 19 can prevent the broken pieces from getting stuck in the inner wall of the crushing wheel 10 on the crushing box 1, thereby ensuring the stable operation of the crushing wheel 10.

[0032] Working principle:

[0033] When the device is in use, it pours the construction waste that needs to be crushed into it, and then crushes the incoming construction waste through the setting of the crushing structure and the rotation of the two sets of crushing wheels 10. When the top electric push rod 7 moves, it can drive the pushing work of the contact plate 8, and then during the crushing work, the construction waste that falls on the top of the crushing box 1 can be squeezed and resisted, and the contact between the auxiliary machine and the crushing wheel 10 can be accelerated. The crushing efficiency of the device is then accelerated. The bottom of the device is provided with an odor output structure, and the bottom discharging structure is provided with a magnetic guide structure to slow down the discharging rate and ensure that the device can perform stable discharging work.
