DETAILED DESCRIPTION

[0042] In order to make the objectives, technical solutions and advantages of this application more clear, the present application is further described in detail below in conjunction with examples and drawings. The schematic implementation methods of this application and their descriptions are only used to explain this application and are not intended to limit this application.

[0043] like Figure 1 As shown, an embodiment of the present application provides a sludge conveying device, which includes a first belt conveyor 1, a slag blocking plate 2, a second belt conveyor 3 and a switching power source 4.

[0044] One section of the first belt conveyor 1 is used to be arranged obliquely below the shield slag screw machine. In actual implementation, the first belt conveyor 1 can be installed in the tunnel through a support frame. The first belt conveyor 1 can be divided into two sections along its length, one of which is located below the screw machine and parallel to the screw machine, and the other is horizontal; wherein the length direction of the other section is not limited to a straight line, a broken line, a curve, etc. The first belt conveyor 1 includes a frame, a belt, a driving shaft, a driven shaft and support rollers. The frame is used to support the entire first belt conveyor 1. During actual installation, the support frame can be used as the frame. Of course, the frame can also be independently connected to the support frame to improve maintenance convenience. The driving shaft is rotatably set at one end of the frame, and the driven shaft is rotatably set at the other end of the frame. When in use, the driven shaft is located below the screw machine. The belt cooperates with the driving shaft and the driven shaft respectively and is tensioned by the driving shaft and the driven shaft. The rollers are connected to the frame and used to support the belt.

[0045] A plurality of slag retaining plates 2 are arranged on the first belt conveyor 1 to enclose a slag retaining trough with one side open; in actual implementation, the number of slag retaining plates 2 is at least three, two of which are located on both sides of the first belt conveyor 1, and the plate surfaces of the two slag retaining plates 2 are parallel to the conveying direction of the first belt conveyor 1, and the other slag retaining plate 2 is vertically connected between the two slag retaining plates 2, two of which are used to prevent the slag on the first belt conveyor 1 from overflowing to both sides, and the other slag retaining plate 2 is used to prevent the slag from overflowing downward along the inclined direction.

[0046] The two ends of the second belt conveyor 3 are rotationally connected to the first belt conveyor 1 through the first rotating component 5 and the second rotating component 6 respectively, which means that the first rotating component 5 is rotationally connected to the first belt conveyor 1 and the second belt conveyor 3 respectively, and the second rotating component 6 is rotationally connected to the first belt conveyor 1 and the second belt conveyor 3 respectively. The length direction of the second belt conveyor 3 is parallel to the length direction of one segment of the first belt conveyor 1 and a plurality of scrapers 7 are provided on the belt of the second belt conveyor 3. The plurality of scrapers 7 are arranged in parallel and at intervals along the length direction of the second belt conveyor 3. The driving shaft of the second belt conveyor 3 is also transmission-connected to the driven shaft of the first belt conveyor 1 through the first rotating component 5, which means that after the first belt conveyor 1 is started, its driven shaft can drive the driving shaft of the second belt conveyor 3 to rotate synchronously, that is, the first belt conveyor 1 and the second belt conveyor 3 have the same conveying speed.

[0047] The switching power source 4 is connected to the second rotating assembly 6 to drive the second rotating assembly 6 to rotate, thereby making the second belt conveyor 3 approach to or move away from the first belt conveyor 1 .

[0048] Under normal slag discharging conditions, the first belt conveyor 1 is located below the screw machine, and the slag sent by the screw machine falls onto the first belt conveyor 1. The moisture content of these slags is low, and there is a large friction between them and the belt of the first belt conveyor 1. The slag itself has a good shape-retaining ability and will not slide down the slope during the transportation by the first belt conveyor 1, so it can be transported normally. When gushing occurs, the moisture content in the slag is high, and the slag becomes thin slag. The thin slag has a certain fluidity, and when it falls onto the first belt conveyor 1, it will slide downward along the slope and gather at the end of the slag retaining trough. By switching the driving source, the second rotating assembly 6 is driven to rotate, and the first A rotating component 5 rotates synchronously, the second belt conveyor 3 is close to the first belt conveyor 1, and the scraper 7 on the second belt conveyor 3 has a very small distance from the first belt conveyor 1, or is in direct contact with the first belt conveyor 1. The second belt conveyor 3 runs synchronously driven by the first belt conveyor 1, so the scraper 7 on the second belt conveyor 3 can scrape the thin slag in the slag retaining groove, which means that there is thin slag between every two scrapers 7. The thin slag is difficult to slide down the inclined surface under the blocking action of the scraper 7, which is equivalent to maintaining the shape of the thin slag through the scraper 7, so that the thin slag moves upward along the inclined surface driven by the scraper 7 and the first belt conveyor 1, thereby realizing the transportation of the thin slag.

[0049] The slag conveying device provided in the embodiment of the present application can block the slag at the gushing location through the slag trough formed by the slag blocking plate 2 to prevent it from falling from the first belt conveyor 1; after the second belt conveyor 3 is rotatably connected to the first belt conveyor 1 through the first rotating component 5 and the second rotating component 6, the second rotating component 6 is driven to rotate by switching the power source 4 to make the second belt conveyor 3 close to the first belt conveyor 1, and at the same time, the second belt conveyor 3 can be close to the end of the slag blocking trough, so that the scraper 7 on the second belt conveyor 3 can scrape off a large amount of slag at the end of the slag blocking trough, assisting the first belt conveyor 1 to transport the slag and avoiding excessive accumulation of slag in the slag blocking trough; after the gushing ends, the second rotating component 6 is driven to rotate by switching the power source 4 to make the second belt conveyor 3 away from the first belt conveyor 1, so as to avoid the second belt conveyor 3 affecting the conveying function of the first belt conveyor 1.

[0050] In the slag conveying device provided in the embodiment of the present application, the operation of the second belt conveyor 3 does not need to rely on an independent power source, but is driven by the first belt conveyor 1. On the one hand, it is conducive to the simplification of the structure. On the other hand, the scraper 7 on the second belt conveyor 3 and the first belt conveyor 1 do not generate relative speed, and the scraper 7 and the first belt conveyor 1 do not generate mutual wear, which is conducive to maintaining the shape of the slag.

[0051] In some optional embodiments, please refer to Figure 1 and Figure 2 The first rotating component 5 can specifically include a first swing shaft 51 and a first swing rod; the first swing shaft 51 is rotatably connected to the first belt conveyor 1 so that the first swing shaft 51 can rotate freely around its own axis, and the first swing shaft 51 is also transmission-connected to the driving shaft of the second belt conveyor 3 to rotate synchronously. In actual implementation, considering that the relative position of the driving shaft of the second belt conveyor 3 and the first swing shaft 51 is not fixed, a belt transmission is preferably adopted between the driving shaft of the second belt conveyor 3 and the first swing shaft 51; one end of the first swing rod is rotatably connected to the first swing shaft 51 so that the first swing rod can rotate freely around the axis of the first swing shaft 51, and the other end is rotatably connected to the driving shaft of the second belt conveyor 3 so that the first swing rod can rotate freely around the axis of the driving shaft.

[0052] In some optional embodiments, an elastic member is provided between the first swing arm and the first belt conveyor 1 to impart a rotational tendency to the first swing arm. With this arrangement, the elastic force provided by the elastic member can provide tension to the belt of the second belt conveyor 3. Since the second belt conveyor 3 does not bear the weight of the soil, a belt retaining structure can be omitted in the second belt conveyor 3, thereby simplifying the structure of the second belt conveyor 3. Specifically, the second belt conveyor 3 can include only a belt, a driving shaft, a driven shaft, and a scraper 7 provided on the belt.

[0053] In some optional embodiments, see Figure 2 The first swing arm includes a first sub-rod 52, a second sub-rod 54, and an intermediate movable shaft 53. One end of the first sub-rod 52 is rotatably connected to the first swing shaft 51, and the other end of the first sub-rod 52 is higher than the second belt conveyor 3 in the normal direction of the belt surface of the second belt conveyor 3. One end of the second sub-rod 54 is rotatably connected to the driving shaft of the second belt conveyor 3. The intermediate movable shaft 53 is rotatably connected to the other ends of both the first sub-rod 52 and the second sub-rod 54. This means that the intermediate movable shaft 53 is movably inserted through both the first sub-rod 52 and the second sub-rod 54. The intermediate movable shaft 53 is also simultaneously connected to the driving shaft of the second belt conveyor 3 and the first swing shaft 51. An elastic member is disposed between the first belt conveyor 1 and the first sub-rod 52 to provide a rotational tendency for the first sub-rod 52, and an elastic member is disposed between the second sub-rod 54 and the first sub-rod 52 to provide a rotational tendency for the second sub-rod 54. This arrangement further improves the first swing arm's ability to tension the belt of the second belt conveyor 3. At the same time, the first sub-rod 52 can be located outside the slag retaining groove, and the second sub-rod 54 can be located inside the slag retaining groove. The power of the first belt conveyor 1 is transmitted to the driven shaft of the second belt conveyor 3 through the intermediate movable shaft 53, so that the transmission structure of the first swing shaft 51 and the first belt conveyor 1 is located outside the slag retaining groove. The transmission structure can be protected from the influence of sludge, ensuring that it can operate normally for a long time.

[0054] In some optional embodiments, the first rotating assembly 5 is connected to the driven shaft of the first belt conveyor 1 through a bevel gear transmission mechanism 8. The bevel gear transmission mechanism 8 has the function of changing the direction of movement, which is conducive to simplifying the structure.

[0055] In some optional embodiments, please refer to Figure 1 and Figure 3The bevel gear transmission mechanism 8 includes a first bevel gear group 81, a first transmission shaft 82, a clutch 83, a second transmission shaft 84 and a second bevel gear group 85; the first bevel gear group 81 is connected to the driven shaft of the first belt conveyor 1, and the first bevel gear group 81 includes two bevel gears that mesh with each other, one of which is coaxially connected to the driven shaft of the first belt conveyor 1; one end of the first transmission shaft 82 is rotatably connected to the first belt conveyor 1 and is coaxially connected to the other bevel gear in the first bevel gear group 81 to rotate synchronously with the driven shaft of the first belt conveyor 1; the clutch 83 is connected to the other end of the first transmission shaft 82; one end of the second transmission shaft 84 is connected to the clutch 83; the second bevel gear group 85 includes two bevel gears that mesh with each other, one of which is coaxially connected to the second transmission shaft 84, and the other bevel gear is coaxially connected to the first swing shaft 51. With this arrangement, after the gushing ends, the first transmission shaft 82 and the second transmission shaft 84 can be separated by the clutch 83, so that the second belt conveyor 3 will not run synchronously with the first belt conveyor 1, ensuring that the second belt conveyor 3 has a considerable service life.

[0056] In some optional embodiments, the first transmission shaft 82 is connected to the first belt conveyor 1 via a first positioning bearing seat 86. In actual implementation, the number of the first positioning bearing seats 86 can be configured to be two, and the two first positioning bearing seats 86 are arranged at intervals along the axial direction of the first transmission shaft 82 and respectively cooperate with the first transmission shaft 82. The provision of the first positioning bearing seats 86 can ensure that the first transmission shaft 82 has a stable posture during rotation.

[0057] In some optional embodiments, the second transmission shaft 84 is connected to the first belt conveyor 1 via a second positioning bearing seat 87. In actual implementation, the number of the second positioning bearing seats 87 can be configured to be two, and the two second positioning bearing seats 87 are arranged at intervals along the axial direction of the second transmission shaft 84 and respectively cooperate with the second transmission shaft 84. The provision of the second positioning bearing seats 87 can ensure that the second transmission shaft 84 has a stable posture during rotation.

[0058] In some optional embodiments, the second rotating assembly 6 includes a second swing shaft and a second swing rod; the second swing shaft is rotationally connected to the first belt conveyor 1 so that the second swing shaft can rotate freely around its own axis; one end of the second swing rod is rotationally connected to the second swing shaft so that the second swing rod can rotate freely around the axis of the second swing shaft, and the other end is rotationally connected to the driven shaft of the second belt conveyor 3 so that the second swing rod can rotate freely around the axis of the driven shaft.

[0059] In some optional embodiments, the switching power source 4 is configured as a telescopic member. In actual implementation, the switching power source 4 can be configured as a cylinder, wherein the fixed end of the telescopic member is rotatably connected to the first belt conveyor 1, the moving end is rotatably connected to the middle of the second swing arm, and the fixed end and the second swing axis are spaced apart along the length direction of the first belt conveyor 1. Therefore, by controlling the extension and contraction of the telescopic member, the second swing arm can be driven to rotate on the first belt conveyor 1, thereby driving the second belt conveyor 3 to move closer to or away from the first belt conveyor 1.

[0060] In some optional embodiments, in order to better support the second belt conveyor 3, a first auxiliary rotating assembly 9 and a second auxiliary rotating assembly may be further included. The first auxiliary rotating assembly 9 corresponds to the position of the first rotating assembly 5 in the width direction of the second belt conveyor 3 and is respectively located on both sides of the second belt conveyor 3. The second auxiliary rotating assembly corresponds to the position of the second rotating assembly 6 in the width direction of the second belt conveyor 3 and is respectively located on both sides of the second belt conveyor 3; the first auxiliary rotating assembly 9 includes an auxiliary rotating shaft, an auxiliary swing rod, an auxiliary intermediate rod and an auxiliary driving rod. The auxiliary rotating shaft is connected to the first belt conveyor 1, the auxiliary swing rod is rotatably connected to the auxiliary rotating shaft, the auxiliary intermediate rod is rotatably connected to the auxiliary swing rod, one end of the auxiliary driving rod is rotatably connected to the auxiliary intermediate rod, and the other end is rotatably connected to the driving shaft of the second belt conveyor 3; the structure of the second auxiliary rotating assembly can be set to be the same as the second rotating assembly 6.

[0061] In some optional embodiments, the surface of the scraper 7 forms an angle with the belt surface. This arrangement allows the side of the scraper 7 away from the belt to be inserted into the accumulated slag, providing a better scraping effect. At the same time, the belt of the second belt conveyor 3 is less likely to be locally deformed during the process of conveying the slag, thereby facilitating the conveyance of the slag.
