The waste is quantitatively discharged through the discharge block, and the waste between the two crushing rollers is extruded through the pressing plate, so that the waste accumulation between the two crushing rollers can be avoided, the spacing between the two crushing rollers can be adjusted, and different production needs can be met.

Description

Technical Field

[0001] This utility model relates to the field of construction waste crushing, and in particular to a construction waste crushing device for building construction projects. Background Technology

[0002] Construction waste refers to solid waste generated during the construction, renovation, or demolition of buildings. It mainly includes bricks, stones, and slag. After professional sorting and crushing, it can be transformed into recycled aggregates for use in the production of building materials such as road subbases and recycled bricks.

[0003] Most current construction waste crushing devices used in building construction projects crush construction waste by using two fixed crushing rollers. Since construction waste varies in size, it is easy to accumulate between the two crushing rollers, which can cause blockage. Furthermore, the fixed crushing rollers are difficult to adapt to different production needs. Utility Model Content

[0004] To address the shortcomings or defects of the existing technology, this utility model provides a construction waste crushing device for building construction projects. It uses a feeding block to quantitatively feed waste and a pressure plate to squeeze the waste between two crushing rollers, thereby preventing waste from accumulating between the two crushing rollers. At the same time, the distance between the two crushing rollers can be adjusted to adapt to different production needs.

[0005] The technical implementation scheme of this utility model is as follows: a construction waste crushing device for building construction projects, comprising a box body, a feed inlet at the top of the box body, a collection box inserted inside the box body, two feeding plates fixedly connected inside the box body, brushes fixedly connected to each of the two feeding plates, two guide plates fixedly connected inside the box body, a servo motor fixedly connected to the outer wall of the box body, a feeding block rotatably connected inside the box body, one end of the feeding block being fixedly connected to the output shaft of the servo motor, a pressure block slidably connected to the feeding block, the pressure block having an outer arc surface, two limiting posts fixedly connected to the pressure block, two slot plates fixedly connected inside the box body, the feeding block being rotatably connected to both slot plates, two sliders slidably connected to the box body, crushing rollers rotatably connected between the box body and the two sliders, both crushing rollers being located inside the box body, the two crushing rollers respectively contacting the two brushes, a fixing plate fixedly connected to the outer wall of the box body, and an adjustment mechanism provided on the fixing plate.

Detailed Implementation

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example 1 A construction waste crushing device for building construction projects, such as Figures 1-6 As shown, the device includes a housing 1 with a feed inlet at the top. A collection box 2 is inserted inside the housing 1. Two feed plates 4 are fixedly connected inside the housing 1, and brushes 5 are fixedly connected to each of the feed plates 4. Two guide plates 3 are fixedly connected inside the housing 1. A servo motor 6 is fixedly connected to the outer wall of the housing 1. A feed block 7 is rotatably connected inside the housing 1. One end of the feed block 7 is fixedly connected to the output shaft of the servo motor 6. A pressure block 8 is slidably connected to the feed block 7, and the pressure block 8 has an outer arc surface. Two limiting posts 9 are fixedly connected to the pressing block 8. Two groove plates 10 are fixedly connected inside the box body 1. The feeding block 7 is rotatably connected to both groove plates 10. Two sliders 11 are slidably connected to the box body 1. Crushing rollers 12 are rotatably connected between the box body 1 and the two sliders 11. The two crushing rollers 12 are located inside the box body 1. The two crushing rollers 12 are in contact with the two brushes 5 respectively. A fixing plate 13 is fixedly connected to the outer wall of the box body 1. An adjustment mechanism is provided on the fixing plate 13.

[0021] Both of the aforementioned guide vanes 3 are inclined.

[0022] The feeding block 7 has an inner arc groove.

[0023] Both of the slot plates 10 have limit slots, and the two limit posts 9 are respectively located in the limit slots on the two slot plates 10.

[0024] The adjustment mechanism includes a drive motor 141, which is fixedly connected to the fixed plate 13. A rotating shaft 142 is fixedly connected to the output shaft of the drive motor 141. The rotating shaft 142 is rotatably connected to the housing 1. A bevel gear set 143 is provided between the rotating shaft 142 and the two crushing rollers 12. An opening and closing screw 144 is rotatably connected to the fixed plate 13. A handwheel 145 is fixedly connected to one end of the opening and closing screw 144. Two mounting brackets 146 are threadedly connected to the opening and closing screw 144. The rotating shaft 142 passes through the two mounting brackets 146, and the two mounting brackets 146 are rotatably connected to the two bevel gear sets 143 respectively.

[0025] The bevel gear set 143 consists of a driving bevel gear and a driven bevel gear. Two driving bevel gears are slidably connected to the rotating shaft 142. One end of each of the two crushing rollers 12 is fixedly connected to a driven bevel gear. The two driving bevel gears mesh with the two driven bevel gears respectively.

[0026] First, the operator turns handwheel 145, which drives the opening / closing screw 144 to rotate. The two mounting brackets 146 move closer together under the action of the positive and negative threads on the opening / closing screw 144. This movement of the two mounting brackets 146 drives the two bevel gear sets 143 and the two crushing rollers 12 to move closer together to a suitable position. The movement of the two crushing rollers 12 also drives the two sliders 11 to move closer together, thus adjusting the distance between the two crushing rollers 12. Next, the operator feeds waste material into the feed inlet on the housing 1. The waste material falls into the inner arc groove on the discharge block 7. Both the drive motor 141 and the servo motor 6 start. The servo motor 6 drives the discharge block 7 to rotate. The rotation of the discharge block 7 drives the waste material, the pressure block 8, and the two limit posts 9 to rotate. The waste material in the inner arc groove on the discharge block 7 falls between the two crushing rollers 12. Simultaneously, the drive motor 141 drives... The rotating shaft 142 rotates, which in turn drives the two bevel gear sets 143 to rotate. The rotation of the two bevel gear sets 143 drives the two crushing rollers 12 to rotate. The brush 5 cleans the crushing rollers 12. The two crushing rollers 12 work together to crush the waste. The crushed waste falls into the collection box 2 through the two guide plates 3. As the pressure block 8 drives the two limiting posts 9 to continue rotating, the two limiting posts 9 move downward under the action of the limiting grooves on the two slot plates 10. The two limiting posts 9 work together to drive the pressure block 8 to move downward. The pressure block 8 squeezes the waste between the two crushing rollers 12, so that the two crushing rollers 12 can effectively crush the waste. This process is repeated. The waste is quantitatively fed by the feeding block 7. The pressure plate also squeezes the waste between the two crushing rollers 12, which can prevent the waste from accumulating between the two crushing rollers 12. At the same time, the distance between the two crushing rollers 12 can be adjusted to adapt to different production needs.
