Its main purpose is to locate the cutting position so as to facilitate accurate positioning in the subsequent cutting process. Compared with the transmission mold, each sleeper is a separate space enclosed, and the steel bar binding and prestressing treatment of each sleeper need to be operated separately, which has the defect of wasting materials and reducing work efficiency.

[0028] 2. It is necessary to screen the metal particles in the waste in the recycling box. At this time, the screening frame is extended from the screening box to the recycling box. When the rotating motor controls the screening frame to rotate to the lowest point, the electromagnetic component is located in the waste in the recycling box. When the electromagnetic component is energized, it adsorbs the steel bar metal particles in the waste, and then the concrete waste and metal waste in the waste can be screened; when the two winding motors start to wind the stirring cloth, the two ends of the stirring cloth begin to move upward gradually, and the stirring cloth is divided into two parts by the electromagnetic component, and the stirring cloths on both sides of the electromagnetic component gradually approach the electromagnetic component, and the stirring cloth covers the waste toward the electromagnetic component, which is convenient for the electromagnetic component to adsorb the metal waste in the waste. In order to further improve the adsorption effect of metal waste, the beating frame is controlled to move toward the stirring cloth, and the beating groove on the beating block moves to wrap the side wall of the stirring cloth. At this time, the beating rod is controlled to start reciprocating motion. For example, when the beating rod moves toward the left, the stirring cloths on both sides of the electromagnetic component are turned over to the left, and the waste also falls to the left. This process has the effect of stirring the waste. The greater the amplitude of the side turn, the better the stirring effect. At the same time, when the beating rod moves toward the right, the stirring cloth also turns over to the right, which also has the effect of turning the waste to the right. After multiple reciprocating movements, the material is stirred and the electromagnetic component is also convenient for fully adsorbing the metal waste.

[0029] 3. When the electromagnetic component has finished adsorbing the metal waste, the rotating frame rotates the electromagnetic component to the horizontal initial position and pulls the screening frame into the screening box. At this time, the electromagnetic component is powered off. At this time, most of the metal waste falls into the screening box. However, in order to ensure that all the metal waste on the electromagnetic component is thoroughly cleaned, when the two slide rails are energized, the slide bar is affected by the Ampere force and moves on the slide rail toward the direction of the cleaning rod, thereby driving the cleaning ring to move. The moving cleaning ring can scrape off the metal particles remaining on the outer wall of the electromagnetic component. When the cleaning ring squeezes the cleaning rod, the cleaning rod first processes the metal waste adhered to the end of the cleaning ring, and at the same time, the spring on the cleaning rod is squeezed and deformed. When the slide rail is powered off, the cleaning rod can also push in the opposite direction. During the process, the metal waste adhered to the cleaning ring can also be vibrated off, thereby ensuring that the electromagnetic component is cleaned. BRIEF DESCRIPTION OF THE DRAWINGS

That is, when the screening frame 11 is located in the screening box 10, the screening frame 11 blocks the screening port 16, and the screening port 16 is set above the waste in the recycling box 9. The reciprocating member 12 can be selected from an electric push rod or a cylinder. When it is necessary to screen the metal particles in the waste in the recycling box 9, the screening frame 11 is extended from the screening box 10 into the recycling box 9. Since the rotating frame 13 is set in a concave shape in this embodiment and the electromagnetic member 15 is fixed at the opening of the rotating frame 13, and one side of the rotating frame 13 is fixedly connected to the output end of the rotating motor 14, when the rotating motor 14 controls the screening frame 11 to rotate to the lowest point, the electromagnetic member 15 is located in the waste in the recycling box 9. The electromagnetic member 15 can be selected from an electromagnet in this embodiment. When the electromagnet is energized, it adsorbs the steel bar metal particles of the waste, and then the concrete waste and metal waste in the waste can be screened.

[0051] Reference Figure 4-Figure 6 The stirring part includes a stirring cloth 17 arranged in the recycling box 9, a traction group for pulling the stirring cloth and a beating group for beating the stirring cloth 17. The stirring cloth 17 is located in the recycling box 9 and fits with the inner wall of the recycling box 9 in the initial state, and the electromagnetic member 15 is located above the stirring cloth 17. The traction group includes two winding motors and two winding rollers 18. The winding roller 18 is rotatably arranged outside the recycling box 9. The winding motor is fixed outside the side wall of the recycling box 9 and is located above the opening of the recycling box 9. The winding motor controls the rotation of the winding roller 18.

The movement of the beating frame 19 and the movement of the beating rod 20 can be controlled by the electric push rod, and the movement direction of the beating frame 19 is perpendicular to the movement direction of the beating rod 20, that is, the movement direction of the beating frame 19 is consistent with the movement direction of the screening frame 11, and the movement direction of the beating rod 20 is set along the movement direction of the stirring cloth 17. A beating groove 22 is set on the beating block 21, and the beating groove 22 is opened at one end facing the stirring cloth 17. The stirring cloth 17 is located in the beating groove 22, and the two beating grooves 22 are in contact with the same side of the stirring cloth; when the two winding motors start to wind the stirring cloth 17, the two ends of the stirring cloth 17 begin to gradually move upward, and the stirring cloth 17 is divided into two parts by the electromagnetic member 15, and is located at the electric The stirring cloths 17 on both sides of the magnetic part 15 gradually approach the electromagnetic part 15, and the stirring cloth covers the waste material toward the electromagnetic part 15, so as to facilitate the electromagnetic part 15 to adsorb the metal waste in the waste material. In order to further improve the adsorption effect of the metal waste, the beating frame 19 is controlled to move toward the stirring cloth 17, and the beating groove 22 on the beating block 21 moves to wrap the side wall of the stirring cloth 17. At this time, the beating rod 20 is controlled to start reciprocating motion. For example, when the beating rod 20 moves toward the left, the stirring cloths 17 on both sides of the electromagnetic part 15 are turned over to the left, and the waste material also falls over to the left. This process has the effect of stirring the waste material. The greater the amplitude of the side turn, the better the stirring effect. At the same time, when the beating rod 20 moves toward the right, the stirring cloth 17 also turns over to the right, which also has the effect of flipping the waste material to the right. After reciprocating many times, the material is stirred and it is also convenient for the electromagnetic part 15 to fully adsorb the metal waste.

[0053] Reference Figure 4-Figure 5The recycling component is also provided with a cleaning part for cleaning the electromagnet 45, the cleaning part includes two slide rails 23, a slide rod 24 that is sleeved and slides between the two slide rails 23, a cleaning ring 25 fixed on the slide rod 24, and a cleaning rod 26.

The slide rod 24 is used to connect the two slide rails 23 and make the two slide rails 23 conductive. The cleaning rod 26 is elastically arranged at the end of the rotating frame 13. The cleaning rod 26 extends out of the rotating frame 13 in the initial state. The end of the rotating frame 13 is provided with an elastic hole 28, and the cleaning rod 26 slides In the elastic hole 28, one end of the elastic hole 28 is fixedly connected with a spring 27, and the other end of the spring 27 is fixedly connected to the inner wall of the end of the elastic hole 28, so as to realize the elastic effect of the cleaning rod 26; when the electromagnetic part 15 completes the adsorption of the metal waste, the rotating frame 13 rotates the electromagnetic part 15 to the horizontal initial position, and pulls the screening frame 11 into the screening box 10. At this time, the electromagnetic part 15 is powered off, and most of the metal waste falls into the screening box 10. However, in order to ensure that all the metal waste on the electromagnetic part 15 is thoroughly cleaned, the two slide rails 23 are powered on at this time, and the two slide rails 23 and the slide rod 24 are and an external DC power supply form a closed loop. According to the flow direction of the current and Ampere's law, the direction of the magnetic flux lines of the two slide rails 23 and the slide rod 24 close to the energized power supply side can be obtained. Then, by the left-hand rule, it can be obtained that the direction of the Ampere force on the slide rod 24 is parallel to the slide rail 23 and points to the cleaning rod 26. That is, when the slide rail 23 is energized, the slide rod 24 is acted upon by the Ampere force and moves on the slide rail 23 toward the cleaning rod 26, thereby driving the cleaning ring 25 to move. The moving cleaning ring 25 can scrape off the metal particles remaining on the outer wall of the electromagnetic component 15. When the cleaning ring 25 squeezes the cleaning rod 26, First, the cleaning rod 26 processes the metal waste adhered to the end of the cleaning ring 25, and at the same time, the spring 27 on the cleaning rod 26 is squeezed and deformed. When the slide rail 23 is powered off, the cleaning rod 26 can also push in the opposite direction and vibrate the metal waste adhered to the cleaning ring 25. When the cleaning ring 25 needs to move in the opposite direction, it only needs to change the direction of the current on each slide rail 23, that is, to switch the positive and negative poles. For example, the positive and negative poles are set at the other end of the slide rail 23 in the opposite way to the previous setting, so as to realize the reciprocating motion of the cleaning ring 25, thereby ensuring that the electromagnetic component 15 is cleaned.

[0056] Reference Figure 6-Figure 8 First, in this embodiment, three adjacent transmission rollers 29 need to be set as a group for detection, that is, before the sleeper is suspended or moved to the transmission roller 29 by other means, the traction rope 31 needs to be pulled to the top of the transmission roller, and at the same time, it is necessary to ensure that the identification rod 37 is located at the lowest end of the identification groove 38. At this time, the traction roller 32 connected to the cleaning cloth 35 is kept stationary, and the other traction roller 32 is controlled to rotate and the traction rope 31 is pulled. If the transmission roller 29 fits tightly with the sleeper block, the tension sensor 34 is pulled to generate tension. The tension sensor 34 can be controlled by the PLC controller to be connected to a buzzer, and then the buzzer makes a sound, which can indicate that the corresponding transmission roller 29 is in a normal position; however, the other two transmission rollers 29 in the same group are still needed for detection. If only one of the transmission rollers 29 is not in close contact with the sleeper block, the traction rope 31 is pulled at this time, and the tension sensor 34 is not subjected to tension, and as the identification rod 3 is continued to be pulled 7 is pulled to move upward in the identification slot 38 until the identification rod 37 moves to the top of the identification slot 38, at which time the identification rod 37 triggers the proximity switch 39, and in this embodiment, it is set that as long as any one of the three identification rods 37 triggers the proximity switch 39, the light source 41 is triggered and turned on, and the color sensor 42 and the light source 41 are respectively located at both ends, and the three color filters 43 are located in the middle. For example, the three color filters 43 are red, green and blue filters 43, respectively. At this time, as long as any one of the identification rods 37 is triggered, the corresponding color filter 43 can be popped out, and the color of the light source 41 received by the color sensor 42 is not the true color of the light source 41. The color sensor 42 can be connected to the drive motor 6 through the PLC control, that is, the drive motor 6 starts to stop working and can only be turned on after the position adjustment of the transmission roller 29 is completed. In this embodiment, due to the large number of transmission rollers, only three transmission rollers 29 in any group need to be detected.

[0057] Reference Figure 6-Figure 8, the recycling box 9 is provided with a brush 44 for lifting, an electromagnet 45 electrically connected to the proximity switch 39 is installed on the top of the identification groove 38, and the electromagnet 45 and the proximity switch 39 are also controlled and connected by a PLC controller, and the identification rod 37 is provided with a plurality of through holes 46, and the identification rod 37 is slidably provided with identification posts 36 in the plurality of through holes 46, and one end of the identification rod 37 extending out of the identification groove 38 is connected with a pressurizing member for pressurizing the identification rod 37, and the brush 44 moves along the vertical direction of the recycling box 9, and the lifting of the brush 44 can be achieved by an electric push rod, and the electromagnet 45 is used to adsorb the identification rod 37 or the slider, and the pressurizing member uses a pressurizing pump, and the inside of the identification rod 37 is pressurized by the pressurizing pump. The position 38 is a sliding fit. As the pressure in the identification rod 37 gradually increases, the marking column in the identification rod 37 is pushed out and stabilized, and the identification column 36 is aligned with the cleaning cloth 35. When the recycling box 9 moves to the bottom of the corresponding cleaning cloth 35, the brush 44 rises to abut against the bottom surface of the cleaning cloth 35, and the identification column 36 abuts against the upper surface of the cleaning cloth 35. At this time, the cleaning cloth 35 is controlled to reciprocate. During this process, the tension sensor 34 does not exceed the set tension value. Under the friction of the identification column 36 and the brush 44, the cleaning effect of the cleaning cloth 35 is achieved; when there is no air pressure in the identification rod 37, the identification column 36 is located in the identification rod 37, and is located in the identification rod 37 due to the pulling action of the cleaning cloth 35.

[0058] The implementation principle of the production process of a long rail sleeper in the embodiment of the present application is as follows: when it is necessary to screen the metal particles in the waste in the recycling box 9, the screening frame 11 is extended from the screening box 10 into the recycling box 9, and when the rotating motor 14 controls the screening frame 11 to rotate to the lowest point, the electromagnetic component 15 is located in the waste in the recycling box 9, and when the electromagnetic component 15 is energized, it adsorbs the steel bar metal particles in the waste, and then can screen the concrete waste and metal waste in the waste; when the two winding motors start to wind the stirring cloth 17, the two ends of the stirring cloth 17 begin to gradually move upward, and the stirring cloth 17 is divided into two parts by the electromagnetic component 15, and the stirring cloths 17 located on both sides of the electromagnetic component 15 gradually approach the electromagnetic component 15, and the stirring cloth covers the waste toward the electromagnetic component 15, which is convenient for The electromagnetic component 15 adsorbs the metal waste in the waste. In order to further improve the adsorption effect of the metal waste, the knocking frame 19 is controlled to move toward the stirring cloth 17, and the knocking groove 22 on the knocking block 21 moves to wrap the side wall of the stirring cloth 17. At this time, the knocking rod 20 is controlled to start reciprocating motion. For example, when the knocking rod 20 moves toward the left, the stirring cloths 17 on both sides of the electromagnetic component 15 are turned over to the left, and the waste also falls to the left. This process has the effect of stirring the waste. The greater the amplitude of the side turn, the better the stirring effect. At the same time, when the knocking rod 20 moves toward the right, the stirring cloth 17 also turns over to the right, which also has the effect of flipping the waste to the right. After multiple reciprocating movements, the material is stirred and the electromagnetic component 15 is also convenient for fully adsorbing the metal waste.

[0059] When the electromagnetic component 15 has completed the adsorption of the metal waste, the rotating frame 13 rotates the electromagnetic component 15 to the horizontal initial position and pulls the screening frame 11 into the screening box 10. At this time, the electromagnetic component 15 is powered off. At this time, most of the metal waste falls into the screening box 10. However, in order to ensure that all the metal waste on the electromagnetic component 15 is thoroughly cleaned, when the two slide rails 23 are energized, the slide bar 24 is affected by the Ampere force and moves on the slide rail 23 toward the direction of the cleaning rod 26, thereby driving the cleaning ring 25 to move. The moving cleaning ring 25 can scrape off the metal particles remaining on the outer wall of the electromagnetic component 15. When the cleaning ring 25 squeezes the cleaning rod 26, the cleaning rod 26 first processes the metal waste adhered to the end of the cleaning ring 25, and the spring 27 on the cleaning rod 26 is squeezed and deformed. When the slide rail 23 is powered off, the cleaning rod 26 can also push in the opposite direction. During the process, the metal waste adhered to the cleaning ring 25 can also be vibrated off, thereby ensuring that the electromagnetic component 15 is cleaned.

[0060] Before the sleeper is suspended or moved to the transmission roller 29 by other means, the traction rope 31 needs to be pulled to the top of the transmission roller, and at the same time, it is necessary to ensure that the identification rod 37 is located at the lowest end of the identification groove 38. At this time, the traction roller 32 connected to the cleaning cloth 35 is kept stationary, and the other traction roller 32 is controlled to rotate and the traction rope 31 is pulled. If the transmission roller 29 fits tightly with the sleeper block, the tension sensor 34 is pulled to generate tension, and the buzzer sounds, which can indicate that the corresponding transmission roller 29 is in the normal position; if as long as one of the transmission rollers 29 is not in close contact with the sleeper block, the traction sensor 34 is pulled at this time. The guide rope 31 and the tension sensor 34 are not subjected to tension, but as the marking rod 37 continues to be pulled, it is pulled to move upward in the marking slot 38 until the marking rod 37 moves to the top of the marking slot 38. The marking rod 37 triggers the proximity switch 39, and the corresponding color filter 43 can pop out. At this time, the color of the light source 41 received by the color sensor 42 is not the true color of the light source 41. The color sensor 42 triggers the drive motor 6 to stop working and can not be turned on until the position adjustment of the transmission roller 29 is completed. In this embodiment, due to the large number of transmission rollers, only three transmission rollers 29 in any group need to be detected.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
