Description

Technical Field

[0001] This utility model relates to the field of belt conveyor guide troughs, and in particular to a special guide trough for corrugated sidewall belt conveyors. Background Technology

[0002] With the increasing demand for large-angle material conveying in industries such as mining, metallurgy, and chemicals, traditional flat belt conveyors are unable to meet the requirements of high-efficiency operation due to problems such as easy material slippage and limited conveying angle. Corrugated sidewall belt conveyors, through the innovative use of a conveyor belt structure with corrugated sidewalls, have successfully achieved continuous conveying at a maximum angle of 60°, significantly reducing the equipment footprint and energy consumption losses in the transfer process.

[0003] However, this type of corrugated sidewall belt conveyor faces the problem of serious material spillage in the transfer area during actual operation. The solution is to add a material guiding device in the transfer area. However, the material guiding device uses an anti-overflow skirt that comes into contact with the conveyor belt. The anti-overflow skirt is usually made of rubber. This design makes the anti-overflow skirt easy to wear and requires frequent replacement, resulting in low economic efficiency. In addition, the conveyor belt will also experience wear. Utility Model Content

[0004] To overcome the problems of severe material spillage in the transfer area and wear caused by contact between the material guide device and the conveyor belt in the aforementioned background technology, this utility model provides a special material guide chute for corrugated sidewall belt conveyors. By setting a simplified sealing mechanism, a continuous leak-proof material guide chute is produced, which not only solves the problem of severe spillage in the transfer area, but also avoids wear caused by contact between the material guide chute and the corrugated sidewall conveyor belt. It has the beneficial effects of high reliability, reduced equipment wear, greatly reduced material conveying waste, high conveying rate, and can meet the dual requirements of structural simplification and functional reliability of lightweight conveying systems.

[0005] The technical solution of this utility model is as follows:

[0006] A special guide trough for a corrugated sidewall conveyor includes a guide trough body covering the corrugated sidewall conveyor belt. The guide trough body includes a cover plate and side plates fixed on both sides of the cover plate. A sealing element is fixed at the bottom of the side plate. The sealing element extends along the length of the side plate and is arranged inside the corrugated sidewall conveyor belt with a gap therebetween.

[0007] Compared with existing technologies, the beneficial effects of this technical solution are as follows:

[0008] By placing the seals inside the corrugated sidewall conveyor belt, it is possible to better reduce material spillage from the edge of the chute body, thereby reducing the maintenance workload of the conveyor. In addition, the gap between the seals and the corrugated sidewall conveyor belt can prevent wear when they come into contact.

[0009] Preferably, the side plate is perpendicularly connected to the cover plate; the side plate is an integral structure, including a top surface, a side surface and a bottom surface, and is a groove-shaped structure with its groove opening facing outward and overlapping with the inner side of the corrugated sidewall conveyor belt in the vertical direction.

[0010] Its beneficial effects are: the grooves of the side plates face outward and overlap with the inner side of the corrugated sidewall conveyor belt in the vertical direction, which can basically control the material inside the corrugated sidewall conveyor belt and further prevent the material from being thrown to the outside.

[0011] More preferably, the top surface and the side surface of the seal are vertically connected, with its top surface fixed parallel to the bottom surface of the side plate, and its side surface located inside the corrugated sidewall conveyor belt.

[0012] Its beneficial effect is that the material that falls onto the opening above the corrugated sidewall conveyor belt will directly collide with the inner wall of the seal and bounce back into the corrugated sidewall conveyor belt, instead of spilling out from the edge of the guide chute body. This can better prevent the material from leaking out and causing serious waste.

[0013] More preferably, a gap is left between the side of the seal and the inner side of the corrugated sidewall conveyor belt, and a gap is left between its top surface and the top of the corrugated sidewall conveyor belt.

[0014] Its beneficial effect is that the fixed seal will not come into contact with the moving corrugated sidewall conveyor belt, so there will be no wear between the two.

[0015] More preferably, the distance between the top and side surfaces of the seal and the top and inner sides of the corrugated sidewall conveyor belt is 5-10 mm; the seal is made of angle steel.

[0016] Its beneficial effects are as follows: this distance range prevents the seals from contacting the corrugated sidewall conveyor belt, thus avoiding disruption to its normal operation, and also better confines the material within the belt, further preventing spillage. Angle steel is inexpensive to produce and easy to manufacture; using it instead of spillage skirts further reduces production costs.

[0017] More preferably, the top and bottom surfaces of the side plate are provided with a plurality of connecting holes evenly arranged along their length direction. Fasteners pass through the connecting holes to fix the top and bottom surfaces of the side plate to the edge of the cover plate and the top surface of the seal, respectively.

[0018] Its advantages are: by using fasteners, the stability of the connection can be guaranteed, and the components can be transported separately during the transportation of this device, which is convenient for transportation, and the structure is simple, easy to install, and has low production cost.

[0019] More preferably, a number of stiffening plates are fixed in the groove of the side plate, and the top and bottom surfaces of the side plate are welded and fixed to the upper and lower ends of the stiffening plates; the front and rear ends of the cover plate and the side plate are respectively fixed with a front curtain and a rear baffle by connectors.

[0020] Its beneficial effects are as follows: the ribs enhance the structural strength of the trough body and extend its service life; the welding method also improves the connection strength at the joints. The front curtain and rear baffle are key components for ensuring the sealing of the conveyor belt transfer area; their combined action prevents material entering the trough body from spreading forward and backward.

[0021] Preferably, support frames are fixed on both sides of the guide trough body, the support frames on both sides are symmetrically arranged, and the support frames on each side are arranged along the length direction of the guide trough body; the support frames are fixedly connected to the intermediate frame.

[0022] Its beneficial effect is that the support frame is used to fix the material guide chute body on the intermediate frame, so that it can be stably erected and covered above the corrugated sidewall conveyor belt.

[0023] More preferably, the support frame includes a horizontal bar and a vertical bar of integral structure, one end of the horizontal bar extends toward the side plate and is fixedly connected to the side plate; the bottom end of the vertical bar extends downward and is fixedly connected to the intermediate frame.

[0024] Its beneficial effect is that by setting horizontal and vertical bars to connect with the side plates and the intermediate frame respectively, the material guide trough body can be connected with the intermediate frame.

[0025] More preferably, a connecting plate is fixed below the top surface of the side plate, and an adjusting horizontal hole is provided on the connecting plate. The horizontal bar is detachably and fixedly connected to the adjusting horizontal hole by fasteners, and its position can be adjusted within the adjusting horizontal hole. An adjusting vertical hole is provided on the bottom surface of the vertical bar, and the intermediate frame is detachably and fixedly connected to the adjusting vertical hole by fasteners, and the connection position of the vertical bar can be adjusted within the adjusting vertical hole. A diagonal brace connecting the horizontal bar and the vertical bar is fixed on one side of the support frame.

[0026] Its beneficial effects are as follows: The adjustable horizontal holes allow the support frame to be adjusted left and right within a certain range to connect with the material guide trough body, adapting to intermediate frames of varying widths and thus increasing the applicability of the material guide trough. The adjustable vertical holes allow for vertical adjustment of the connection position between the material guide trough body and the intermediate frame within a certain range, enabling the support frame height to be adjusted according to the height of the intermediate frame, further enhancing the applicability of the material guide trough. The diagonal braces enhance the support strength and structural stability of the support frame. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] Example 1: As Figures 1 to 2 The diagram shows a special guide chute for a corrugated sidewall conveyor, including a guide chute body 1. The guide chute body 1 is arranged above and covers the corrugated sidewall conveyor belt 2 in the transfer area, which can form a semi-enclosed channel above the corrugated sidewall conveyor belt 2. The material sliding into the guide chute body 1 from the transfer chute will be confined within the guide chute body 1, which greatly reduces the problem of serious material spillage in the transfer area.

[0033] The feed chute body 1 includes a cover plate 11 and side plates 12 fixed to the lower sides of both sides of the cover plate 11. A sealing element 13 is fixed to the bottom of the side plate 12, and the sealing element 13 extends along the length of the side plate 12. The sealing element 13 is arranged inside the corrugated sidewall conveyor belt 2, with a gap between them. By arranging the sealing element 13 inside the corrugated sidewall conveyor belt 2, it is possible to better reduce the spillage of material from the edge of the feed chute body 1, thereby reducing the maintenance workload of the conveyor. In addition, the gap between the sealing element 13 and the corrugated sidewall conveyor belt 2 can prevent wear when they come into contact.

[0034] Example 2: Based on Example 1, the side plate 12 and the seal 13 are optimized. The side plate 12 is perpendicularly connected to the cover plate 11 and together cover the corrugated sidewall conveyor belt 2. The width of the cover plate 11 is set according to the bandwidth of the corrugated sidewall conveyor belt. The side plate 12 is an integral structure, including the top surface, side surface and bottom surface that are integral structures. The side plate 12 is a groove structure with a cross-section in the shape of "]". Its groove faces outward and overlaps with the inner side of the corrugated sidewall conveyor belt 2 in the vertical direction. That is, the side plate 12 is recessed towards the inner side of the corrugated sidewall conveyor belt 2. This method can basically control the material inside the corrugated sidewall conveyor belt 2 and further prevent the material from being thrown to the outside.

[0035] Furthermore, the top and side surfaces of the seal 13 are vertically connected and are made of a single piece of angle steel. Angle steel is inexpensive, easy to manufacture, and readily available, making it a suitable alternative to the anti-overflow skirt, thus reducing production costs. The top surface of the seal 13 is located below and parallel to the bottom surface of the side plate 12. The side surface of the seal 13 is positioned inside the corrugated sidewall conveyor belt 2 and extends downwards into it. This ensures that material spilling onto the opening above the corrugated sidewall conveyor belt 2 will directly collide with the inner wall of the seal 13, bounce off, and fall back into the conveyor belt 2, preventing spillage from the edge of the guide chute body 1. This effectively avoids material leakage and significant waste. Additionally, the side surface of the seal 13 does not extend inwards beyond the side surface of the side plate 12, preventing material accumulation on the top surface of the seal 13.

[0036] More preferably, the side of the seal 13 is left with a gap between it and the inner side of the corrugated sidewall conveyor belt 2, and its top surface is left with a gap between it and the top of the corrugated sidewall conveyor belt 2. Thus, the fixed seal 13 will not come into contact with the moving corrugated sidewall conveyor belt 2, and no wear will occur between the two.

[0037] The gaps between the side of the seal 13 and the inner side of the corrugated sidewall conveyor belt 2, and the gaps between the top surface of the seal 13 and the top of the corrugated sidewall conveyor belt 2, are both 5-10mm. This range will not allow the seal 13 to contact the corrugated sidewall conveyor belt 2 and affect its normal operation, and it will also better confine the material inside the corrugated sidewall conveyor belt 2, further preventing the material from being thrown outside the corrugated sidewall conveyor belt 2.

[0038] Furthermore, the top and bottom surfaces of the side plate 12 are provided with several connecting holes 3 evenly arranged along its length. Fasteners pass through the connecting holes 3 to fix the top and bottom surfaces of the side plate 12 to the edge of the cover plate 11 and the top surface of the seal 13, respectively. Bolts are used as fasteners, and nuts that are connected to them are used to detachably connect the upper and lower surfaces of the side plate 12 to the cover plate 11 and the seal 13. This ensures the stability of the connection and allows the components to be transported separately during the transportation of the device, making transportation convenient. The structure is simple, the installation is convenient, and the production cost is low.

[0039] Among them, a number of stiffening plates 121 are fixed in the groove of the side plate 12. The upper and lower ends of the stiffening plates 121 are welded and fixed to the top and bottom surfaces of the side plate 12. The stiffening plates 121 can enhance the structural strength of the guide trough body 1 and extend its service life. The welding method can also improve the connection strength at the joint.

[0040] The front and rear ends of the cover plate 11 and side plate 12 are respectively fixed with a front curtain and a rear baffle by connectors 5. That is, the front end of the cover plate 11 and side plate 12 along the running direction of the corrugated side conveyor belt 2 is fixed with a front curtain by connectors 5, and the rear end of both are fixed with a rear baffle by connectors 5. The front curtain and the rear baffle are both fixed to the upper part of the guide chute body 1. The actual installation height is set according to the actual site conditions. The connector 5 is an angle steel structure, and several connecting holes 3 are opened on its two sides. The connecting holes 3 are used to fix the connector 5 to the cover plate 11 and side plate 12 by bolt connection, and to install and fix the front curtain and the rear baffle to the connector 5.

[0041] The front curtain and rear baffle are key components for ensuring the sealing of the conveyor belt transfer area. Their combined action prevents material entering the guide chute body 1 from spreading forward and backward. The front curtain is located at the feed end of the guide chute body 1, i.e., at the connection with the transfer chute. Material can slide into the guide chute body 1 along the transfer chute and is evenly dispersed under the guidance of the front curtain, preventing it from overflowing from above the corrugated sidewall conveyor belt 2 after entering the guide chute body 1 too quickly or in excessive amounts. The rear curtain is located at the discharge end of the guide chute body 1, ensuring orderly material discharge.

[0042] Example 3: Based on Example 1, a preferred design is made. Support frames 4 are fixed on both sides of the guide trough body 1. The support frames 4 on both sides are symmetrically arranged. The support frames 4 on each side are evenly arranged along the length of the guide trough body 1. The number of support frames 4 on each side is determined according to the length of the guide trough body 1. The support frames 4 are fixedly connected to the intermediate frame. The support frames 4 are used to fix the guide trough body 1 on the intermediate frame so that it can be stably erected and covered above the corrugated sidewall conveyor belt 2.

[0043] Specifically, the support frame 4 includes an integral horizontal bar 41 and a vertical bar 42, which are perpendicular to each other. The structure has a horizontal bar 41, one end of which extends towards the side plate 12 and is fixedly connected to the top surface of the side plate 12; the bottom end of the vertical bar 42 extends downward and is fixedly connected to the intermediate frame. By setting the horizontal bar 41 and the vertical bar 42 to be connected to the side plate 12 and the intermediate frame respectively, the guide trough body 1 can be connected to the intermediate frame.

[0044] Furthermore, a connecting plate 6 is fixed below the top surface of the side plate 12. The connecting plate 6 has an adjusting horizontal hole 61, which is an elongated hole whose length direction is consistent with the length direction of the crossbar 41. The crossbar 41 is detachably fixed to the adjusting horizontal hole 61 by fasteners, and its position can be adjusted back and forth along the length direction of the crossbar 41 within the adjusting horizontal hole 61. Bolts are used as fasteners, passing through the adjusting horizontal hole 61 and the crossbar 41, and are fixed to the side plate 12 and the support frame 4 by engaging with corresponding nuts. The adjusting horizontal hole 61 allows the support frame 4 to be adjusted left and right within a certain range to connect with the guide trough body 1, adapting to intermediate frames with different widths and improving the applicability of this guide trough.

[0045] The bottom surface of the vertical rod 42 has an adjustment hole 421. This adjustment hole 421 is an elongated hole, and its length direction is consistent with the length direction of the vertical rod 42. The intermediate frame is detachably fixed to the adjustment hole 421 by fasteners, and the position of the vertical rod 42 can be adjusted up and down within the adjustment hole 421. The fasteners are bolts, which pass through the adjustment hole 421 and the vertical rod 42 and are connected by corresponding nuts to fix the intermediate frame and the support frame 4. The setting of the adjustment hole 421 allows the connection position between the guide trough body 1 and the intermediate frame to be adjusted up and down within a certain range. It also allows the height of the support frame 4 to be adjusted according to the height of the intermediate frame, further improving the applicability of this guide trough.

[0046] One side of the support frame 4 is welded with a diagonal brace 43 that connects its horizontal bar 41 and vertical bar 42. The diagonal brace 43 can enhance the support strength and structural stability of the support frame 4.

[0047] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the technical solution of this application, and these all fall within the scope of protection of this application.
