[0002] During the construction project, a large amount of solid waste will be generated, which needs to be crushed regularly. These solid wastes mainly contain bricks, gravel, slag, concrete fragments, building materials plastic packaging bags and building materials packaging boxes, etc. Solid waste contains more recyclable resources, such as steel bars wrapped in concrete and metal objects such as nails.

[0003] However, after the existing solid waste treatment equipment for construction projects crushes the concrete, it is necessary to transport the concrete to a designated location for further processing by a transport vehicle.

In the process of transportation by the transport vehicle, some concrete particles smaller than the fine particles will be lost through the gaps on the transport vehicle, thereby causing a waste of resources. At the same time, since the crushed concrete contains some metal objects, the metal objects contained in the concrete need to be separated during the screening process of the crushed concrete, which increases the difficulty of the staff's work.

[0052] It also includes a metal separation mechanism; the metal separation mechanism includes a rotating ring 6, which is rotatably connected to the inner wall of the crushing box 1.

[0053] The electromagnet 7 is fixedly connected to the side wall of the rotating ring 6 , and a conductive block 8 is fixedly connected to the end of the electromagnet 7 .

The crushing teeth 12 on the two crushing rollers 2 cooperate with each other, and the two crushing rollers 2 rotate towards each other, and the block concrete is poured into between the two crushing rollers 2 through the feeding funnel 3. In the process of the two crushing rollers 2 rotating towards each other, the crushing rollers 2 and the crushing teeth 12 squeeze the block concrete, thereby achieving the crushing process of the block concrete.

When the concrete contains steel bars and the diameter of the steel bars is greater than the distance between the two crushing rollers 2, since the steel bars have a certain toughness and are difficult to break, the mutual pushing force between the steel bars and the crushing rollers 2 causes one of the crushing rollers 2 to slide to one side, that is, the sliding block 16 drives the crushing roller 2 connected thereto to move to one side, and in the process of moving the sliding block 16, the spring 15 gradually contracts. When the steel bars slide down between the two crushing rollers 2 and fall onto the filter screen 4, at this time, through the elastic force of the spring 15, the spring 15 moves the sliding block 16 and the crushing roller 2 connected thereto closer to the other crushing roller 2.

[0060] The first drive motor 17 is fixedly connected to the outer wall of the crushing box 1 and the side wall of the sliding block 16 , and the output shaft of the first drive motor 17 is fixedly connected to the rotating shaft 13 .

[0061] A connecting rod 18 is fixedly connected to the side wall of the electromagnet 7 , and one end of the connecting rod 18 is fixedly connected to the side wall of the conductive block 8 .

[0062] The wire on the electromagnet 7 passes through the connecting rod 18 and is connected to the conductive block 8. The rotating ring 6 and the connecting rod 18 are made of insulating materials. The electromagnet 7 is rectangular. When the annular rotating plate 6 drives the electromagnet 7 to rotate to the lower side of the arc output plate 9, the lower end of the electromagnet 7 is in contact with the upper surface of the fixed plate 5. The material of the arc output plate 9 is a magnetic shielding material, which is convenient for isolating the magnetic force on the electromagnet 7 on the lower side of the arc output plate 9. There are two electromagnets 7, and the two electromagnets 7 are symmetrically arranged about the arc output plate 9.

[0063] A support plate 20 is fixedly connected to the outer wall of the crushing box 1, a cover plate 21 is fixedly connected to the side wall of the support plate 20, the end of the rotating ring 6 connected to the conductive block 8 is inserted in the cover plate 21, and an arc-shaped power transmission block 22 is fixedly connected to the side wall of the cover plate 21, the arc-shaped power transmission block 22 cooperates with the conductive block 8, the cover plate 21 is annular, and an annular groove is opened on the side wall of the cover plate 21, the end of the rotating ring 6 and the conductive block 8 are inserted in the annular groove, the arc-shaped power transmission block 22 is fixedly connected to the side wall of the annular groove, and the opening of the arc-shaped power transmission block 22 is arranged upward, and the arc-shaped power transmission block The curvature of 22 is greater than that of the arc output plate 9, and the open end of the arc transmission block 22 matches the open end of the arc output plate 9, and the arc output plate 9 is inclined. The upper end of the arc output plate 9 passes through the cover plate 21 and is fixedly connected to the side wall of the support plate 20 on one side of the crushing box 1, and the lower end of the arc output plate 9 passes through the side wall of the crushing box 1 and is fixedly connected to the support plate 20 on the other side of the crushing box 1. A circular through hole is opened on the support plate 20 located at the lower side of the arc output plate 9, and the circular through hole is used for the lower end of the arc output plate 9 to pass through. The conveying mechanism is located at the lower side of the arc output plate 9.

[0064] There are two rotating rings 6, which are respectively located at the two ends of the electromagnet 7, and the two rotating rings 6 are covered with a cover plate 21. The outer wall of the crushing box 1 is fixedly connected with a power storage device in the prior art, such as a battery. The wires on the battery are respectively connected to the arc-shaped power transmission blocks 22 in the two cover plates 21, that is, the positive and negative electrodes on the battery are respectively connected to the two arc-shaped power transmission blocks 22 through wires. When the conductive block 8 contacts the arc-shaped power transmission block 22, the electromagnet 7 is energized. When the rotating ring 6 drives the electromagnet 7 to rotate to the bottom of the arc output plate 9 When the arc output plate 9 is moved to the top, the metal objects in the concrete on the fixed plate 5 are adsorbed on the electromagnet 7 by the magnetic force of the electromagnet 7. When the rotating ring 6 drives the electromagnet 7 to rotate to the top of the arc output plate 9, the conductive block 8 is located at the upper end of the arc transmission block 22, that is, the conductive block 8 is out of contact with the arc transmission block 22, and the conductive block 8 is in a power-off state. At this time, the electromagnet 7 loses its magnetic force, and the metal objects adsorbed on the electromagnet 7 slide down into the arc output plate 9 due to the action of gravity, thereby realizing the separation of the metal objects contained in the concrete.

[0065] The wires on the battery are connected to the arc-shaped power transmission block 22 through a controller, so that the controller can be used to control the amount of electricity input from the battery into the arc-shaped power transmission block 22 and its opening and closing.

[0068] A lead screw 26 symmetrical about the arc output plate 9 is rotatably connected to the side wall of the support plate 20, and a push block 27 is threadedly connected to the lead screw 26. The push block 27 is slidably connected to the outer side wall of the arc output plate 9, and the lower surface of the push block 27 contacts the upper surface of the arc output plate 9.

[0069] A servo motor 28 is fixedly connected to the side wall of the support plate 20, and a rotating shaft 29 is fixedly connected to the end of the lead screw 26. The rotating shaft 29 is rotatably connected to the side wall of the support plate 20, and a first sprocket 30 is fixedly connected to the servo motor 28 and the rotating shaft 29, and a first chain 31 is sleeved on the first sprocket 30.

The slider 33 is slidably connected in the strip-shaped slide groove 32. A nut is fixedly connected to the push block 27, and the nut is threadedly connected to the lead screw 26. The thread on the nut cooperates with the thread on the lead screw 26, so that the lead screw 26 drives the push block 27 to move through the nut. Due to the cooperation between the strip-shaped slide groove 32 and the slider 33, the push block 27 is prevented from rotating with the rotation of the lead screw 26, and the threads on the two lead screws 26 are arranged in opposite directions. When the two servo motors 28 drive the two lead screws 26 to rotate simultaneously, the two servo motors 28 drive the two lead screws 26 to rotate simultaneously. When the electromagnet 7 rotates in the opposite direction, the push blocks 27 on the two lead screws 26 move in the opposite direction. When the metal on the electromagnet 7 falls to the upper surface of the arc output plate 9, and both ends of the metal object are located on the surface of the arc output plate 9 and are laterally stuck on the upper end surface of the arc output plate 9, due to the opposite movement of the two push blocks 27, when the two push blocks 27 move to the two ends of the metal object laterally stuck on the arc output plate 9, the two push blocks 27 push the two ends of the metal object in the opposite direction, thereby facilitating the metal object laterally stuck on the arc output plate 9 to fall onto the arc output plate 9, and facilitating the metal object to slide out of the crushing box 1 through the lower end of the arc output plate 9.

[0071] The conveying mechanism includes a support frame 34 , one end of which is fixedly connected to the outer wall of the crushing box 1 , and the lower end surface of the support frame 34 is flush with the lower surface of the bottom plate of the crushing box 1 .

[0077] A plurality of steel bar classification holes 41 are provided on the discharge plate 10, and the collection box 11 is located directly below the steel bar classification holes 41, and the collection box 11 cooperates with the steel bar classification holes 41, and the length values ​​of the steel bar classification holes 41 gradually increase from top to bottom, and the number of the steel bar classification holes 41 decreases from top to bottom, that is, the first row of steel bar classification holes 41 located on the upper part of the discharge plate 10 has the smallest length value, and the number is not less than two, the length value of the second row of steel bar classification holes 41 is greater than the length value of the first row of steel bar classification holes 41, and the number is less than the number value of the first row of steel bar classification holes 41, thereby facilitating the classification and collection of steel bars of various different lengths.

[0078] A vertically arranged partition 42 is fixedly connected to the bottom of the crushing box 1, and the upper end of the partition 42 is fixedly connected to the lower surface of the fixed plate 5, and the partition 42 is located at the connecting portion between the fixed plate 5 and the filter screen 4. Storage boxes 43 are arranged on the lower sides of the filter screen 4 and the fixed plate 5. A discharge port 44 is provided at one end of the fixed plate 5 away from the filter screen 4. The discharge port 44 is connected to the lower side of the fixed plate 5. Two exits are provided on the side wall of the crushing box 1, and the exits are used for placing and taking out the storage box 43.

[0079] Working principle: The staff connects the wires on the first drive motor 17, the second drive motor 23, the servo motor 28, and the third drive motor 39 to the existing power supply, and then pours the solid concrete blocks for construction into the crushing box 1 through the feed funnel 3, and starts the first drive motor 17. The output shafts of the two first drive motors 17 drive the two crushing rollers 2 to rotate in opposite directions. The two crushing rollers 2 crush the concrete in the process of rotating in opposite directions, and the crushed concrete falls down to the filter screen 4. When the concrete is wrapped with metal objects such as steel bars and nails, the crushing rollers 2 crush the concrete. After the soil is crushed, the metal objects and the crushed concrete fall downward onto the filter screen 4 between the two crushing rollers 2, and the concrete and metal objects on the filter screen 4 slide down the inclined surface of the filter screen 4 and fall onto the fixed plate 5. In the process of the crushed concrete and metal objects sliding down the inclined surface of the filter screen 4, the fine concrete particles slide downward through the mesh holes on the filter screen 4 to the storage box 43 below it, thereby realizing the screening and distinction of the crushed concrete with smaller particle size values, concrete with larger particle size values ​​and metal, which is convenient for the recycling of concrete with smaller particle size values ​​and concrete with larger particle size values.

[0080] Start the second drive motor 23 and the controller, the battery transmits power to the arc-shaped power transmission block 22 through the controller, and transmits power to the electromagnet 7 through the arc-shaped power transmission block 22 and the conductive block 8. During the operation of the second drive motor 23, the output of the second drive motor 23 drives the rotating ring 6 to rotate through the meshing of the gear 24 and the outer gear ring 25, thereby driving the electromagnet 7 to rotate. When the rotating ring 6 drives the electromagnet 7 to rotate downward, and the lower end of the electromagnet 7 contacts the upper surface of the fixed plate 5, that is, when the electromagnet 7 rotates to the lowest end of the rotating ring 6, the metal object in contact with it is moved by the magnetic force of the electromagnet 7. It is adsorbed on the electromagnet 7. At the same time, when the rotating ring 6 drives the lowermost electromagnet 7 to rotate upward, the lower end of the electromagnet 7 pushes the concrete on the fixed plate 5 toward the discharge port 44, so that the concrete with a larger particle size value slides downward through the discharge port 44 to the storage box 43 below it, which is convenient for the staff to recycle the concrete with a larger particle size value. One end of the fixed plate 5 where the discharge port 44 is provided is tilted upward, so that the concrete and metal objects that slide off the filter screen 4 are convenient to accumulate on the fixed plate 5, thereby effectively preventing the metal objects from sliding through the upper surface of the fixed plate 5 into the discharge port 44.

[0081] When the rotating ring 6 drives the electromagnet 7 with the metal adsorbed thereon to rotate upward to the highest point of the rotating ring 6, the conductive block 8 connected to the electromagnet 7 with the metal adsorbed thereon is located at the opening of the upper end of the arc-shaped power transmission block 22, and the electromagnet 7 is located directly above the arc-shaped output plate 9, that is, the conductive blocks 8 at both ends of the electromagnet 7 are separated from the contact with the arc-shaped power transmission block 22, the electromagnet 7 is in a power-off state, and the electromagnet 7 loses its magnetic force. When the metal loses its magnetic force, it falls toward the arc-shaped output plate 9 due to gravity, and slides out of the crushing box through the lower end of the arc-shaped output plate 9. 1. When the metal object falls downward to the upper end surface of the arc output plate 9 through the electromagnet 7, at this time, the servo motor 28 is started, and the output shaft of the servo motor 28 drives the lead screw 26 to rotate through the cooperation of the first sprocket 30 and the first chain 31. The lead screw 26 drives the push block 27 to move during the rotation process, so that the push block 27 pushes the metal object falling on the upper end surface of the arc output plate 9 to one side, so that the metal object on the arc output plate 9 is convenient to fall downward into the arc output plate 9 or fall downward onto the fixed plate 5 through the gap between the outer arc wall of the arc output plate 9 and the electromagnet 7.

[0082] When the metal object slides downward from the lower end of the arc output plate 9 to the discharge plate 10, the metal object slides downward through the inclined surface of the discharge plate 10. When the metal object passes through the steel bar classification holes 41, the steel bar segments and nails fall downward from short to long through the steel bar classification holes 41 from top to bottom on the discharge plate 10 to the collection box 11 below it, that is, the shorter steel bar segments and nails fall through the steel bar classification holes 41 on the upper side of the discharge plate 10 to the collection box 11 below it, while the longer steel bar segments and nails, because their length is greater than The length value of the steel bar classification hole 41 at the upper end of the discharge plate 10 is such that the longer steel bar segments and nails cannot fall through the shorter steel bar classification holes 41 when they slide downward. When the steel bar segments and nails slide downward to the steel bar classification holes corresponding to their length values, the steel bar segments and nails slide downward through the steel bar classification holes 41 into the collection box 11 on the lower side thereof, thereby collecting steel bar segments and nails of different lengths, thereby facilitating the staff to recycle steel bar segments and nails of different length values.

[0083] When the steel bar segment is long and stuck between the arc output plate 9 and the stop rod 40, the third drive motor 39 is started, and the output shaft of the third drive motor 39 drives the second chain 37 to rotate through the transmission roller 35. During the rotation of the second chain 37, the push rod 38 is driven to rotate. When the second chain 37 drives the push rod 38 to move between the discharge plate 10 and the arc output plate 9, during the movement of the push rod 38, the steel bar segment or nail stuck between the lower end of the arc output plate 9 and the stop rod 40 is pushed in the direction of movement of the push rod 38. When the upper ends of the steel bar segment and the nail are separated from the lower end of the arc output plate 9, the lower ends of the steel bar segment and the nail cannot move forward with the push rod 38 due to the blocking of the stop rod 40. As the push rod 38 gradually approaches the stop rod 40, the push rod 38 pushes the side wall of the steel bar segment and the nail, causing the upper ends of the steel bar segment and the nail to rotate upward. When the steel bar segment and the nail are in a vertical state, the push rod 38 pushes the upper ends of the vertical steel bar segment and the nail to fall in the moving direction of the push rod 38. The gap between the push rods 38 adjacent to the moving direction of the push rods 38 falls downward onto the discharge plate 10, thereby preventing the steel bar segment and the nail from being stuck between the arc output plate 9 and the stop rod 40. When the length of the steel bar segment and the nail is greater than the distance between the two adjacent push rods 38, when the upper ends of the steel bar segment and the nail stuck between the arc output plate 9 and the stop rod 40 fall onto the push rod 38 adjacent to the moving direction of the push rod 38, the push rod 38 moves forward, and the steel bar segment and the nail have a certain weight, and the stop rod 40 can block the steel bar segment. As well as the blocking of the lower end of the nail, the resistance of the steel bar segment and the nail moving with the push rod 38 is increased, and in the process of the push rod 38 moving forward, the distance value between the push rod 38 and the blocking rod 40 that blocks the lower end of the steel bar segment is increased, so that the steel bar segment is convenient to fall downward to the discharge plate 10 through the gap between the blocking rod 40 and the push rod 38, thereby realizing the separation and discharge of the separated steel bar segment and metal objects such as nails, and at the same time facilitating the distinguishing and collection of steel bar segments and nails of different lengths, which brings convenience to the staff.
