It will rebound after the external force disappears, and the connecting block 45 can provide support for the brush plate 50. The brush plate 50 and the elastic sheet 48 can cooperate to provide support for the wire brush 49.

[0043] In actual application of this embodiment, when the inclined arc plate 15 is moved along the inclined arc groove 14 toward the direction close to the curved pipe 10 by the centrifugal force, the inclined arc plate 15 will use external force to pull the wire rope 35, so that the wire rope 35 can be pulled along the curved hole 34 under the action of external force. At the same time, the wire rope 35 will pull the lifting plate 37 under the action of external force and the resistance of the cone sleeve 9, so that the lifting plate 37 uses external force to overcome the friction between the rubber strip 38 and the cone sleeve 9, thereby driving the rubber strip 38 to move downward along the lifting groove 33. As the clean water stored in the inclined arc groove 14 is gradually discharged, the rubber strip 38 and the lifting plate 37 will gradually move toward the direction close to the curved pipe 10 along with the inclined arc plate 15, so that the lifting plate 37 gradually approaches the switch 36. Finally, when the curved pipe 10 cannot be pushed by the inclined arc plate 15 to spray clean water in atomized form, the lifting plate 37 will contact and squeeze the trigger switch 36, so that the switch 36 controls the electric rod 40 to start extending. When the electric rod 40 is extended, it pushes the inclined plate 42 downward under the support of the support plate 39, so that the inclined plate 42 pushes the elastic sheet 48 and the brush plate 50 downward through the connecting block 45 and the rail 46, so that the wire brush 49 contacts the inner wall of the cone crusher 1, and the elastic sheet 48 and the brush plate 50 gradually descend, and under the resistance of the cone crusher 1, the elastic sheet 48 and the wire brush 49 fixed on one side are squeezed, so that the elastic sheet 48 is squeezed and deformed under the action of external force, so that it is gradually straightened. At the same time, the elastic sheet 48 pushes the connecting block 45 under the action of external force, so that the connecting block 45 With the support of the blocking ball 47, the rail 46 is driven to move along the inner groove 44 and the rail groove 43 away from the guard plate 41. At the same time, the connecting block 45 will drive the brush plate 50 to move together, so that the brush plate 50 can be lowered, and then the wire brush 49 can be moved to fit the inner wall of the cone crusher 1. At this time, the concrete injection is stopped. At the same time, the cone sleeve 9 will use the rotational power to drive the wire brush 49 to rotate together through the support plate 39, the electric rod 40, the inclined plate 42, the connecting block 45, the elastic sheet 48 and the brush plate 50, so that the wire brush 49 can clean the inner wall of the cone crusher 1.

[0044] After the cleaning is completed, the staff can control the motor 5 to stop running and stop the cone sleeve 9 from rotating. At this time, the inclined arc plate 15 will use its own gravity to push the annular sealing strip 16 and the rubber ring 17 to move downward along the inclined arc groove 14 to reset. At the same time, the inclined arc plate 15 will push the wire rope 35 to move along the curved hole 34 to the inner side of the lifting groove 33, so that the wire rope 35 can push the lifting plate 37 to overcome the friction between the rubber strip 38 and the cone sleeve 9 under the action of external force, so that the rubber strip 38 and the lifting plate 37 can move along the lifting groove 14 to reset. The drop groove 33 moves upward to reset, and at the same time, the lifting plate 37 is separated from the switch 36, so that the switch 36 pops up, controls the electric rod 40 to shrink, and drives the wire brush 49 to separate from the cone crusher 1 through the inclined plate 42, the elastic sheet 48 and the brush plate 50. At the same time, the elastic sheet 48 will rebound by its own elastic force. The end of the elastic sheet 48 away from the connecting block 45 is fixedly connected to the inclined plate 42, so that the elastic sheet 48 uses the elastic force to pull the connecting block 45 and the brush plate 50 along the rail groove 43 to move and reset in the direction close to the guard plate 41.

[0045] At the same time, the guard plate 41 and the inclined plate 42 can provide protection for the wire brush 49 and the electric rod 40 to prevent them from being damaged by concrete. Finally, the staff needs to refill clean water into the inclined arc groove 14 from the quick-closing interface 12, and then start the motor 5 to run the recycling and utilization device of the building concrete.

[0046] As a preferred embodiment of the present invention, a recycling method of a recycling device for building concrete, the recycling method of the recycling device for building concrete comprises: The construction concrete recycling device is fixed to the work site through the frame 2 by using the fixing components, and the motor 5 is powered on and started, so that the motor 5 drives the cone crusher 1 to operate; The construction concrete to be recycled is continuously injected into the inner side of the expansion bucket 23, so that the construction concrete can fall into the inner side of the cone crusher 1 along the expansion bucket 23 under the action of gravity to be crushed; When the motor 5 drives the cone crusher 1 to operate, it will drive the storage and spraying parts in the rotating part to rotate, so that the cone sleeve 9 set in the storage and spraying parts drives the curved pipe 10 to rotate together, and the curved pipe 10 drives the pulley 32 set in the pusher in the pre-crushing part to rotate together, so that the pulley 32 pushes the biting part, so that the clamping plate 27 and the triangular plate 28 set in the biting part can be pushed to reciprocate and translate, and drive the crushing teeth 29 to pre-crush the initial building concrete put into the expansion bucket 23 during the translation process, and the pre-crushed concrete will fall into the cone crusher 1 under the action of gravity for further crushing; As time goes by and work proceeds, the inclined arc plate 15 set in the water pushing part will gradually move upward along the inclined arc groove 14, and pull the wire rope 35 set in the triggering part during the movement. When the inclined arc plate 15 moves to a position close to the curved pipe 10, it will trigger the switch 36 through the wire rope 35 and the lifting plate 37. The switch 36 then controls the electric rod 40 set in the cleaning part to extend, pushing the wire brush 49 to contact the inner wall of the cone crusher 1, and at the same time stops injecting concrete, so that the wire brush 49 rotates with the cone sleeve 9, and washes and cleans the concrete material adhered to the inner wall of the cone crusher 1 while rotating. Finally, the motor 5 is stopped, and clean water is added to the inside of the cone sleeve 9, and then the crushing work of recycling the building concrete is resumed.

[0047] Working principle: the frame 2 is firmly installed at the workplace through the fixing parts to ensure the stability of the equipment, the pipeline for conveying clean water is connected to the quick-closing interface 12, and clean water is injected into the inclined arc groove 14. The water level is observed through the transparent plate 13, and the pipeline is disconnected after ensuring that the water level is appropriate.

[0048] The motor 5 is started to drive the drive shaft 6 and the cone crusher 1 to start operation, the storage spraying part starts to rotate, and the liquid is sprayed out through the nozzle 11 in atomized form to achieve dust reduction.

[0049] After pouring building concrete into the expansion bucket 23 and starting the motor 5, the curved pipe 10 drives the pulley 32 to push the spring plate 26 and the push rod 25. At the same time, the pulley 32 rotates under the support of the curved pipe 10, so that the crushing teeth 29 on the clamping plate 27 and the triangular plate 28 pre-crush the concrete.

[0050] The pre-crushed concrete enters the cone crusher 1 for further crushing to achieve effective recycling.

[0051] The inclined arc plate 15 moves by centrifugal force, triggering the cleaning member to start, so that the electric rod 40 extends, pushing the brush plate 50 and the wire brush 49 to clean the inner wall of the cone crusher 1.

[0052] Stop the motor 5, the bevel plate 15 and the wire rope 35 are reset under the action of gravity, and push the lifting plate 37 to reset, thereby promoting the reset of the cleaning piece, preparing for the next use, and repeating all the above steps.

[0053] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
