[0019] The first aspect of the present invention provides an intelligent shield slag screening and processing device, such as Figure 1 and Figure 2 As shown, an intelligent shield slag screening and processing device is arranged in a bucket 1 of a slag truck, and the screening and processing device includes a screening drum 2, which is arranged inside the bucket 1 and at its rear end; an accommodating space is formed between the front of the bucket 1 and the screening drum 2, and the screening drum 2 has two discharge ports and one feed port, and the feed port of the screening drum 2 faces the accommodating space; The screening and processing device also includes a separate material rack 3 and a push-off mechanism 5; the separate material rack 3 is installed inside the screening barrel 2, and the separate material rack 3 is used to stir the slag in the screening barrel 2 so that the slag screened by the screening barrel 2 is discharged from a discharge port thereof; The push-off mechanism 5 is installed on the screening drum 2 , and is used to discharge the unscreened debris in the screening drum 2 from the two discharge ports of the screening drum 2 .

[0020] One discharge port of the screening drum 2 is communicated with the discharge port at the rear of the bucket 1 .

[0021] The screening cylinder 2 is a hollow cylinder structure with openings at both ends; The screening cylinder 2 has a plurality of screening holes 23 distributed near the discharge port at the rear of the bucket 1; One end of the screening drum 2 is provided with an end frame 21 and is fixedly connected to the inner wall of the truck bucket 1, and the other end of the screening drum 2 is communicated with the outside of the side wall of the truck bucket 1; The feed inlet of the screening drum 2 faces the accommodating space of the truck bucket 1, and guide plates 22 are provided on the upper and lower sides of the feed inlet of the screening drum 2, and are distributed in an eight-shaped structure; The upper portion of the screening cylinder 2 is provided with a movable opening 24 along its direction.

[0022] In this embodiment, the slag produced after the shield tunneling will be placed in the accommodating space of the bucket 1 of the slag truck. After the slag truck is driven to the designated position, the bucket 1 is lifted up obliquely by a common vehicle-mounted cylinder. At this time, the debris in the accommodating space of the truck bed 1 will roll into the screening drum 2 due to the action of gravity, and part of the debris entering the screening drum 2 will directly pass through its first discharge port, that is, the screen hole 23, and be discharged through the discharge port at the rear of the truck bed 1; in this process, the separation type material shifting frame 3 is rotated to stir the debris in the screening drum 2, thereby increasing the amount of debris passing through the screen hole 23; Finally, the large pieces of slag that fail to pass through the sieve holes 23 will be discharged from the second discharge port of the screening barrel 2 through the cooperation of the pushing mechanism 5, thereby achieving the flexibility of the overall screening process, avoiding the requirement of the slag screening process for a fixed site, and completing the integration of transportation and screening, thereby improving the efficiency of slag screening.

[0023] As an implementation method, Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, further: The separate material screening frame 3 includes a central axis cylinder 31, which penetrates the end frame 21 and is located inside the screening cylinder 2; The outer wall of the central axis tube is provided with a material shifting plate 32, and the material shifting plate 32 is arranged around the axis of the central axis tube; An elastic body 33 is disposed on the outer edge of the material-diverting plate 32 , and the elastic body 33 is in contact with the inner wall of the screening cylinder 2 .

[0024] In this embodiment, the elastic body 33 is specifically made of polyurethane, rubber composite material or high molecular polyethylene but is not limited thereto.

[0025] The screening and processing device also includes a rotary driver 4 for controlling the rotation of the central axis tube 31, and the rotary driver includes a central axis rod 41 arranged through the central axis tube, and the central axis rod 41 is rotatably connected to the end frame 21; The inner wall of the central axis tube 31 is provided with a convex strip 311 along its axial direction, and the convex strip 311 is arranged around the axis of the central axis tube 31; the outer wall of the central axis rod 41 is provided with a notch corresponding to the convex strip 311, and the central axis tube is slidably connected with the notch of the central axis rod 41 through the convex strip 311; The rotary driver 4 also includes a first servo motor 42, which is installed on the truck bed 1; the output shaft of the first servo motor 42 is provided with a first synchronous wheel 43, and the outer end of the central shaft rod 41 is provided with a second synchronous wheel 44, and the first synchronous wheel 43 and the second synchronous wheel 44 are connected by a synchronous belt transmission.

[0026] In this embodiment, after the slag enters the screening barrel 2, the rotary driver 4 starts to work, the output shaft of the first servo motor 42 drives the first synchronous wheel 43 to rotate, the first synchronous wheel 43 drives the second synchronous wheel 44 to rotate through the synchronous belt, and the second synchronous wheel 44 drives the central axis rod 41 to rotate with it. Since the central axis tube 31 forms a spline-type sliding connection with the central axis rod 41 through the convex strip 311, the central axis tube 31 will be driven to rotate along the axial direction of the screening barrel 2. During the rotation, the material stripping plate 32 will continuously stir and turn the slag in the barrel, thereby increasing the speed and probability of the slag inside the screening barrel 2 passing through its sieve hole 23 area. The elastomer 33 on the outer edge of the material stripping plate 32 also increases the contact and extrusion effect with the slag, and the material of the elastomer 33 will not cause damage to the structure of the screening barrel 2.

[0027] As an implementation method, Figure 6 and Figure 7 As shown, further: The push-off mechanism 5 includes a push plate 51, on which a sleeve is formed, and the push plate 51 is sleeved on the central axis tube through the sleeve and is rotatably connected thereto, and is close to the second synchronous wheel 44 and is located at one end of the screening drum 2; The other end of the screening cylinder 2 is provided with a sealing plate 52, which is sleeved and installed on the central axis tube; The push-off mechanism 5 further comprises a linear drive 53 for driving the push plate 51 to move along the central axis tube, and the linear drive 53 is in driving connection with the sleeve.

[0028] The linear drive 53 includes a shifting frame 531 and a fixing frame 532. The fixing frame 532 is installed on the upper part of the bucket 1. One end of the shifting frame 531 is fixedly connected to the sleeve of the push plate 51, and the other end of the shifting frame 531 passes through the movable opening 24 and is slidably connected to the fixing frame 532. A threaded rod 533 is rotatably provided on the fixing frame 532 , and the threaded rod 533 penetrates the shifting frame 531 and is threadedly connected thereto. A second servo motor 534 is also fixedly mounted on the fixing frame 532 , and the second servo motor 534 is drivingly connected to the threaded rod 533 .

[0029] In this embodiment, since the push plate 51 is sleeved on the middle shaft tube through the sleeve and is rotatably connected thereto, the connection between the push plate 51 and the middle shaft tube 31 will not be affected during the rotation of the middle shaft tube 31. When the large pieces of soil that have not passed through the sieve holes 23 need to be discharged from the second discharge port of the sieve barrel 2, the linear drive 53 starts to work, and the output shaft of the second servo motor 534 controls the threaded rod 533 to rotate. Since the shifting frame 531 is slidably connected to the fixed frame 532 and is threadedly connected to the threaded rod 533, when the threaded rod 533 rotates, the shifting frame 531 will be driven to move along the fixed frame 532, and the shifting frame 531 will also drive the push plate 51 and the separate shifting frame 3 to move with it. Since the central shaft cylinder 31 forms a spline sliding connection with the central shaft rod 41 through the convex strip 311, the movement of the push plate 51 will smoothly drive the separate shifting frame 3 to move smoothly. During the movement, the second discharge port of the screening barrel 2 formed by the sealing plate 52 is opened, and then, under the action of the continuous movement of the push plate 51 , the large pieces of debris inside the screening barrel 2 will be smoothly discharged from the second discharge port of the screening barrel 2 .

[0030] As an implementation method, Figure 8 , Fig. 9 and Figure 5 As shown, further: The screening and processing device also includes a first plate body 61 and a second plate body 62 arranged in the bucket 1, one end of the first plate body 61 is hinged to the front part of the bucket 1; a slide groove is provided on the inner wall of the bucket 1, one end of the second plate body 62 forms a convex column and is located in the slide groove of the inner wall of the bucket 1, and the first plate body 61 and the second plate body 62 are hinged; the inner walls of the first plate body 61 and the second plate body 62 form the inner wall of the accommodating space of the bucket 1; The vibrating mechanism 6 also includes a roller 63 and a transmission mechanism 65. The roller 63 penetrates the bucket 1 and is longitudinally slidably connected thereto. The roller 63 contacts the outer wall of the first plate 61. A roller 631 is provided at the outer end of the roller 63. The transmission mechanism 65 is arranged on the bucket 1, and a wedge block 64 is arranged at the output end of the bucket 1 mechanism. A slope is formed on the wedge block 64 and contacts the roller 631. The transmission mechanism 65 is used to control the moving path of the wedge block 64 to be perpendicular to the moving path of the roller 63.

[0031] The transmission mechanism 65 includes a sliding frame 651, which is slidably arranged on the outer wall of the truck bucket 1, and the sliding direction is arranged horizontally, and the wedge block 64 is installed at one end of the sliding frame 651; Racks 652 are respectively provided on the upper and lower sides of the sliding frame 651; The outer part of the bucket 1 is rotatably provided with a first linkage rod 655 and a second linkage rod 656, which are respectively located at the upper and lower sides of the sliding frame 651, and the first linkage rod 655 is provided with a first gear 6551 and a first half gear 6552, and the second linkage rod 656 is provided with a second gear 6561 and a second half gear 6562. The outer part of the bucket 1 is also rotatably provided with a third gear 657, and the third gear 657 is respectively meshed with the first gear 6551 and the second gear 6561; A third synchronous wheel 653 is disposed on the central shaft rod 41 , a fourth synchronous wheel 654 is disposed on the first link rod 655 , and the third synchronous wheel 653 and the fourth synchronous wheel 654 are connected via a synchronous belt transmission.

[0032] In order to improve the ability of the slag in the bucket 1 to enter the interior of the screening drum 2 more smoothly, in this embodiment, the following solutions are provided: After the slag enters the screening barrel 2, the rotary driver 4 starts to work, the output shaft of the first servo motor 42 drives the first synchronous wheel 43 to rotate, the first synchronous wheel 43 drives the second synchronous wheel 44 to rotate through the synchronous belt, and the second synchronous wheel 44 drives the middle shaft 41 to rotate with it; The middle shaft rod 41 will also drive the third synchronous wheel 653 to rotate, and the third synchronous wheel 653 will drive the fourth synchronous wheel 654 to rotate through the synchronous belt, and the fourth synchronous wheel 654 will drive the first linkage rod 655 to rotate therewith. Since the upper and lower sides of the sliding frame 651 are respectively provided with racks 652, when the first linkage rod 655 rotates, the first half gear 6552 will drive the sliding frame 651 to perform lateral displacement through the rack 652; The wedge block 64 arranged at the end of the sliding frame 651 will also move with it, because the roller 63 contacts the slope of the wedge block 64 through the roller 631, so the roller 63 will produce an upward or downward displacement action, and this action of the roller 63 will change the angle of the first plate 61, and because one end of the first plate 61 is hinged to the front of the truck bucket 1; the inner wall of the truck bucket 1 is provided with a slide groove, one end of the second plate 62 forms a convex column and is located in the slide groove of the inner wall of the truck bucket 1, and the first plate 61 and the second plate 62 are hinged, so when the angle of the first plate 61 changes, the angle between the first plate 61 and the second plate 62 will also change, and the accommodating space of the truck bucket 1 will expand or shrink, which will cause the loosening of the slag; Because the outside of the truck bed 1 is also rotatably provided with a third gear 657, and the third gear 657 is respectively meshed with the first gear 6551 and the second gear 6561, this will cause the first connecting rod 655 to rotate in the opposite direction through the first gear 6551, the third gear 657 and the second gear 6561, and the first half gear 6552 and the second half gear 6562 have their own characteristics. When the angle is set, after the first half gear 6552 completes the directional drive of the sliding frame 651 once, the second connecting rod 656 will complete the reverse drive of the sliding frame 651 through the second half gear 6562, and finally the accommodating space of the truck bed 1 is continuously expanded or reduced, thereby causing the slag to loosen significantly so that the slag can smoothly enter the screening barrel 2.
