Description

Technical Field

[0001] The utility model relates to the field of belt conveyors, in particular to a belt conveyor feeding device with adjustable sealing performance. Background Art

[0002] The raw fuels used in the blast furnaces of the iron and steel metallurgy industry, such as finished sinter, coke, lump ore, pellet, and other solvents. These raw fuels are generally transported by belt conveyors (also known as "belt machines"). At the material receiving position of the belt machine during the transportation and transfer of raw fuels, a feeding device needs to be installed to guide and restrict the flow of materials, and at the same time, it can also prevent the materials from spilling during the transfer process and causing dust to escape. However, after most of the existing feeding devices are used for a period of time, the sealing rubber plate in contact with the conveyor belt wears, resulting in a poor sealing effect, causing a large amount of dust to escape during the transfer process of materials, polluting the environment, and increasing the labor intensity of operators when replacing the dust-proof rubber and cleaning the hygiene. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a belt conveyor feeding device with adjustable sealing performance.

[0004] A belt conveyor feeding device with adjustable sealing performance includes two side brackets respectively arranged on the left and right sides of the belt conveyor and an upper bracket connected between the two side brackets.

[0005] A feeding assembly is suspended at the bottom of the upper bracket, and the feeding assembly is located above the conveyor belt of the belt conveyor.

[0006] The feeding assembly includes a fixed vertical rod, a movable plate, and a sealing rubber plate connected in sequence from top to bottom. The top of the fixed vertical rod is fixedly connected to the upper bracket. A horizontal arm is provided at the bottom of the fixed vertical rod. The horizontal arm extends along the conveying direction of the conveyor belt, and a rotating member capable of rotating around the horizontal arm as the central axis is installed on the horizontal arm. The movable plate is fixedly connected to the rotating member.

[0007] An adjusting screw rod is rotatably installed on the side bracket outside the movable plate. The inner end of the adjusting screw rod faces the movable plate and abuts against the movable plate.

[0008] By adjusting the adjusting screw rod to move away from the movable plate, the movable plate rotates downward (i.e., swings outward) under the action of gravity until it abuts against the adjusting screw rod, so as to adjust the gap between the sealing rubber plate and the conveyor belt of the belt conveyor, so that after the bottom edge of the sealing rubber plate wears, the gap between the sealing rubber plate and the conveyor belt of the belt conveyor can be adjusted to a reasonable size, reducing the dust during the transfer process of materials and reducing the labor intensity of operators.

[0009] In the specific implementation process, the material guiding components are symmetrically arranged on the left and right above the conveyor belt.

[0010] Furthermore, a first nut is fixedly installed on the side bracket, and the adjusting screw rod is in threaded connection with the first nut, so that the adjusting screw rod can be rotatably penetrated through the side bracket.

[0011] Furthermore, the movable plate includes a vertical plate and an arc plate. The top of the vertical plate is connected to the rotating part, and the inner side of the bottom of the vertical plate is connected to the top of the arc plate through an angle steel. The sealing rubber plate is then installed at the bottom of the arc plate. In the specific implementation process, full welding is performed between the vertical plate and the angle steel and between the angle steel and the arc plate to achieve sealing. Further, the top of the sealing rubber plate is adapted and fitted to the bottom of the arc plate. A pressing plate is further provided on the side of the top of the sealing rubber plate facing away from the arc plate. A second nut is fixedly installed on the outer side of the pressing plate. First through holes, second through holes and threaded counterbores are respectively provided on the pressing plate, the sealing rubber plate and the arc plate. Screws sequentially pass through the central threaded hole of the second nut, the first through hole, the second through hole from outside to inside and are in threaded connection with the threaded counterbore, so as to fix the sealing rubber plate, and dust is not likely to accumulate.

[0012] Furthermore, a through hole for the fixed vertical rod to pass through is vertically opened on the upper bracket, and a limit nut is installed on the fixed vertical rod above the upper bracket. By rotating the limit nut, the length of the fixed vertical rod extending below the limit nut can be adjusted, so as to adjust the gap between the movable plate and the upper bracket to a reasonable size and reduce dust emission. Further, an upper sealing plate is fixedly covered on the bottom surface of the upper bracket, and a vertical rod through hole for the fixed vertical rod to pass through is opened on the upper sealing plate to prevent dust from accumulating at the joint of the upper bracket and the fixed vertical rod. In the specific implementation process, the upper sealing plate is a double-layer structure formed by superposing a steel plate and a rubber plate. The steel plate is located above the rubber plate, and full welding is performed between the steel plate and the upper bracket; first fixing holes are respectively opened on the steel plates on both sides of the vertical rod through hole, and second fixing holes corresponding to the first fixing holes are opened on the rubber plate; a screw rod sequentially passes through the second fixing hole, the first fixing hole from bottom to top and is locked and fixed by a locking nut at the end.

[0013] Furthermore, preferably, there are multiple fixed vertical rods corresponding to each set of the material guiding components, and all the fixed vertical rods are arranged at intervals along the conveying direction of the conveyor belt; the rotating parts on all the fixed vertical rods are fixedly connected to the movable plate together.

[0016] The following will describe in detail the preferred embodiments of the present utility model with reference to the accompanying drawings.

[0017] Combined with Figure 1 and Figure 2 A material guiding device for a belt conveyor with adjustable sealing performance includes two side brackets 20 respectively arranged on the left and right sides of the belt conveyor 10 and an upper bracket 30 connected and arranged between the two side brackets 20;

[0018] A material guiding component 40 is suspended at the bottom of the upper bracket 30, and the material guiding component 40 is located above the conveyor belt 11 of the belt conveyor 10;

[0019] The material guiding component 40 includes a fixed vertical rod 41, a movable plate 42 and a sealing rubber plate 43 which are sequentially connected from top to bottom. The top of the fixed vertical rod 41 is fixedly connected to the upper bracket 30. A horizontal arm 44 is provided at the bottom of the fixed vertical rod 41. The horizontal arm 44 extends along the conveying direction of the conveyor belt 11, and a rotating member 45 capable of rotating around the horizontal arm 44 as the central axis is installed on the horizontal arm 44. The movable plate 42 is fixedly connected to the rotating member 45;

[0020] An adjusting screw rod 50 is rotatably installed on the side bracket 20 outside the movable plate 42. The inner end of the adjusting screw rod 50 faces the movable plate 42 and abuts against the movable plate 42.

[0021] In the specific implementation process, as Figure 1 shown, the material guiding components 40 are symmetrically arranged on the left and right above the conveyor belt 11.

[0022] As Figure 2 shown, the number of the fixed vertical rods 40 corresponding to one set of the material guiding components 40 can be one, or multiple (for example, two) arranged along the conveying direction of the conveyor belt. When there are multiple fixed vertical rods 40, the rotating members 45 on these multiple fixed vertical rods 40 are jointly fixedly connected to the movable plate 42.

[0023] The utility model adjusts the gap between the sealing rubber plate 43 and the belt conveyor belt 11, so that after the bottom edge of the sealing rubber plate 43 is worn, the gap between the sealing rubber plate 43 and the belt conveyor belt 11 can be adjusted to a reasonable size, reducing the dust during material transfer and reducing the labor intensity of the operator.

[0024] Further, as Figure 1 shown, a first nut 60 is fixedly installed on the side bracket 20, and the adjusting screw rod 50 is in threaded fit with the first nut 60, so that the adjusting screw rod 50 can be rotatably inserted through the side bracket 20. Of course, a threaded hole can also be directly opened on the side bracket 20, and the adjusting screw rod 50 is in threaded fit with the threaded hole. At this time, the first nut 60 does not need to be additionally provided.

[0025] Further, as Figure 1 shown, the movable plate 42 includes a vertical plate 421 and an arc plate 422. The top of the vertical plate 421 is connected to the rotating member 45, and the inner bottom of the vertical plate 421 is connected to the top of the arc plate 422 through an angle steel 423. The sealing rubber plate 43 is further installed at the bottom of the arc plate 422. In the specific implementation process, full welding is performed between the vertical plate 421 and the angle steel 423 and between the angle steel 423 and the arc plate 422 to achieve sealing. Further, as Figure 1 shown, the top of the sealing rubber plate 43 is adaptively fitted with the bottom of the arc plate 422. A pressing plate 70 is further provided on the side of the top of the sealing rubber plate 43 facing away from the arc plate 422. A second nut 80 is fixedly installed on the outside of the pressing plate 70. First through holes, second through holes and threaded counterbores (the first through hole, the second through hole and the threaded counterbore are conventional structures and are not shown) are respectively provided on the pressing plate 70, the sealing rubber plate 43 and the arc plate 422. A screw 90 sequentially passes through the central threaded hole of the second nut 80, the first through hole, the second through hole from outside to inside and is in threaded fit with the threaded counterbore, so as to fix the sealing rubber plate 43, and it is not easy to accumulate dust. Of course, the movable plate 42 can also be a whole steel plate structure.

[0026] Further, as Figure 1 、 Figure 2 shown, a through hole (a conventional structure and not shown) for the fixed vertical rod 41 to pass through is vertically opened on the upper bracket 30, and a limit nut 100 is installed on the fixed vertical rod 41 above the upper bracket 30. By rotating the limit nut 100, the length of the fixed vertical rod 41 extending below the limit nut 100 can be adjusted, so as to adjust the gap between the movable plate 42 and the upper bracket 30 to a reasonable size and reduce dust. Further, in combination with Figure 1 andFigure 2 A top sealing plate 110 is fixedly covered on the bottom surface of the upper support 30. A vertical rod through hole (a conventional structure in the prior art, not shown) for the fixed vertical rod 41 to pass through is formed in the top sealing plate 110, so as to prevent dust accumulation at the joint between the upper support 30 and the fixed vertical rod 41. In the specific implementation process, in combination with Figure 1 and Figure 2 , the top sealing plate 110 is a double-layer structure formed by laminating a steel plate 111 and a rubber plate 112. The steel plate 111 is located above the rubber plate 112, and full welding is performed between the steel plate and the upper support 30. First fixing holes are respectively formed in the steel plates 111 on both sides of the vertical rod through hole, and second fixing holes corresponding to the first fixing holes are formed in the rubber plate 112. A screw 120 sequentially passes through the second fixing hole, the first fixing hole from bottom to top and is locked and fixed by a locking nut 130 at the end. Of course, the fixed vertical rod 41 can also be directly fixed on the upper support 30, but in this case, the gap between the movable plate 42 and the upper support 30 cannot be adjusted, and the dust-raising effect will be slightly worse.

[0027] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
