Description

Technical Field

[0001] The present invention relates to the technical field of conveyors, and particularly to a material conveying device and method for ferrous metal smelting. Background Art

[0002] In the ferrous metal smelting industry, material conveying equipment plays a crucial role. Traditional material conveyor belts usually only have the function of material conveying. However, in actual use, due to the complex working environment and frequent dust generation, the material conveyor belt is prone to dust diffusion caused by jolts during operation, which not only affects the working environment but may also cause damage to the equipment itself and surrounding equipment. In addition, after the material conveyor belt is used, its transfer process is often cumbersome and requires additional handling tools or manpower for movement.

[0003] In response to the above problems, although some material conveying equipment with dust-proof functions has emerged on the market, these equipment are often complex in structure, and the dust-proof structure is separated from the equipment main body, resulting in deficiencies in both dust-proof effect and equipment transfer convenience. At the same time, when the existing equipment is transferred, the dust-proof structure usually needs to be disassembled, which not only increases the operation difficulty but may also cause damage to the dust-proof structure due to frequent disassembly. Summary of the Invention

[0004] The purpose of the present invention is to provide a material conveying device and method for ferrous metal smelting to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A material conveying device for ferrous metal smelting, including a material conveyor belt. A plurality of legs are fixed to the bottom surface of the material conveyor belt. Lapping grooves are formed on both of the two parallel side plates of the material conveyor belt. Lapping plates are inserted into the lapping grooves. A plurality of support plates are fixed to the bottom surface of the lapping plates. The support plates are inserted into the bottom surface of the lapping grooves. The bottom ends of the support plates are rotatably connected with pulleys. A traction plate is inserted into the side plate of the material conveyor belt. Plug blocks are fixed to the surface of the traction plate. The plug blocks are inserted into the surface of the support plates. Three positioning ports are formed on the surface of the support plates.

[0006] A storage rack is fixed to the surface of the lapping plate. A dust-proof cover one and a dust-proof cover two are fixed inside the storage rack. Two groups of dust-proof cover twos are connected by a magic tape one. The dust-proof cover one and the side plate of the material conveyor belt are connected by a magic tape two.

[0007] Preferably, the length of the long side of the lapping groove is less than the length of the long side of the side plate of the material conveyor. A first through hole is formed in the bottom surface of the lapping groove. There are multiple first through holes, and the multiple first through holes are arranged and distributed at equal distances and with equal sizes along the long side of the bottom surface of the lapping groove. The support plates correspond to the first through holes one by one. The support plates penetrate through the first through holes. A wheel groove is formed in the bottom surface of the support plate. A first limiting shaft is fixed between two parallel side walls of the wheel groove. The pulley is sleeved on the shaft body of the first limiting shaft.

[0008] Preferably, a side groove is formed in the side plate of the material conveyor. A second through hole is formed in the surface of the side groove. The second through hole corresponds to the first through hole one by one, and the second through hole is communicated with the first through hole. The insertion block penetrates through the second through hole and is inserted into the positioning hole.

[0009] Preferably, when the insertion block is inserted into the upper positioning hole, the support leg is suspended and the pulley contacts the ground; when the insertion block is inserted into the middle positioning hole, the pulley is suspended and the support leg contacts the ground; when the insertion block is inserted into the bottom positioning hole, the support plate is lifted and the support leg contacts the ground.

[0010] Preferably, sliding grooves are formed at both ends of the side plate of the material conveyor. A slider is slidably connected inside the sliding groove. The slider is a "U"-shaped plate. One end of the slider is fixed on the surface of the traction plate. A stop block is inserted into the slider. The stop block is fixed on the surface of the sliding groove.

[0011] Preferably, a notch is formed in the surface of the traction plate. An elastic rubber belt is fixed on the surface of the notch. The elastic rubber belt is in the shape of an "I"-shaped plate structure. Both ends of the elastic rubber belt are fixed on the side plate of the material conveyor, and both ends of the elastic rubber belt are respectively distributed on the upper and lower sides of the side groove. A handle is fixed on the surface of the traction plate.

[0012] Preferably, a storage groove is formed in the top surface of the lapping plate. There are two storage grooves, and the two storage grooves are symmetrically distributed about the center of the top surface of the lapping plate. A second limiting shaft is fixed on the bottom surface of the storage groove. The second limiting shaft is a "T"-shaped cylinder. The shaft body of the second limiting shaft penetrates through a through hole. The through hole is formed in the surface of the extension plate. One end of the extension plate is fixed with a rubber clamping block. After the extension plate is folded in the storage groove, the rubber clamping block is squeezed between the extension plate and the storage groove to generate elastic deformation. Two screw connection grooves are formed at one end of the extension plate close to the second limiting shaft. The two screw connection grooves are perpendicular. A hand-tightening screw is screwed on the inner wall of the storage rack. One end of the hand-tightening screw is screwed into the screw connection groove.

On both sides of one end of the second dust cover, a second male magic tape and a third female magic tape are respectively fixed. A first female magic tape is fixed on the side plate of the material conveyor. After the first dust cover is pulled out from the storage rack, the first male magic tape and the first female magic tape are connected in cooperation. After the two second dust covers are pulled out, the two second dust covers are stacked vertically and displaced. At this time, the second male magic tape and the third female magic tape are connected in cooperation.

[0014] Preferably, a reserved groove is formed on the surface of the traction plate for avoiding the servo drive motor installed on the surface of the material conveyor.

[0015] A method for using a material conveying device for ferrous metal smelting, the method comprising the following steps:

[0016] Equipment preparation: Ensure that all components of the material conveyor, such as the legs and the overlapping plates, are in good condition. Store the first dust cover and the second dust cover in the storage rack to ensure that they do not interfere with the normal operation of the equipment;

[0017] Equipment startup: Support the material conveyor through multiple legs to ensure that the equipment is placed stably. The plug should pass through the corresponding second through-hole and be inserted into the positioning hole in the middle to make the pulley suspended, avoiding unnecessary movement during the conveying process. Start the servo drive motor of the material conveyor to start conveying ferrous metal smelting materials;

[0018] Dust prevention measures: During the operation of the equipment, in order to avoid dust diffusion, it is necessary to unfold the dust cover for enclosure. Hold the handle and tension the traction plate to pull the plug out of the positioning hole. Dial the connecting rod to drive the lifting of multiple support plates until the connecting rod is blocked by the side plate of the material conveyor. Turn out the extension plate from the storage groove and fix it in the screw connection groove by hand-tightening the screw to provide stable support. Pull out the first dust cover and the second dust cover and connect them to the side plate and the upper and lower sides of the material conveyor through magic tapes respectively to form an enclosure structure;

[0019] Stop the equipment operation and fold the dust cover: After the material conveying is completed, turn off the servo drive motor of the material conveyor, loosen the hand-tightened screw, push the extension plate back into the storage groove, separate the magic tape, remove the first dust cover and the second dust cover from the enclosure structure, and store them in the storage rack again to ensure that the dust cover is completely stored and does not interfere with the subsequent operation of the equipment;

[0020] Equipment sliding transfer: Lift the equipment from one side of the material conveyor to make the legs suspended. Pull the traction plate to drive the plug out of the positioning hole in the middle. Dial the support plate downward to make the pulley contact the ground. Repeat the above operation to ensure that the pulley on the other side also contacts the ground. Push the material conveyor and use the pulley to slide and transfer it to the designated position;

[0021] Equipment parking: After reaching the designated position, place the material conveyor belt machine steadily. By adjusting the positions of the traction plate and the insertion block, make the legs contact the ground again to provide stable support for the equipment. Sort out the sundries around the equipment to ensure that the equipment is in a clean and safe state.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] The material conveying equipment and method for ferrous metal smelting proposed by the present invention realize an integrated design through the enclosure structure (including dust cover one and dust cover two) and the support structure (i.e., support plate, pulley, connecting rod, etc.). During the material conveying process, the enclosure structure can effectively prevent dust diffusion and protect the equipment and the surrounding environment; when the equipment needs to be transferred, the bracket of the enclosure structure (i.e., the support structure) can also be used as the support for sliding transfer, enabling the convenient movement of the equipment without disassembly. Due to the integrated design of the enclosure structure and the support structure, the material conveyor belt machine in the present invention does not require additional handling tools or manpower during transfer. Only by adjusting the position of the insertion block in the positioning hole can the equipment be quickly switched from the stable support state to the sliding transfer state. This not only simplifies the operation process but also reduces the cost of equipment transfer. By designing the bracket of the enclosure structure as the support structure for sliding transfer, the material conveyor belt machine in the present invention realizes true "multi-purpose in one". This not only improves the utilization rate of the equipment but also makes the equipment more comprehensive and flexible in function. Brief Description of the Drawings

Detailed implementation manners

[0040] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0041] Example 1, please refer to Figures 1 to 15, the present invention provides a technical solution: a material conveying device for ferrous metal smelting, including a material conveyor 1. A plurality of legs 2 are fixed to the bottom surface of the material conveyor 1. Lapping grooves 3 are formed on both of the two parallel side plates of the material conveyor 1. A lapping plate 4 is inserted into the lapping groove 3. A plurality of support plates 5 are fixed to the bottom surface of the lapping plate 4. The support plates 5 are inserted into the bottom surface of the lapping groove 3. The bottom end of the support plate 5 is rotatably connected with a pulley 9. The length of the long side of the lapping groove 3 is less than the length of the long side of the side plate of the material conveyor 1. A first through opening 6 is formed on the bottom surface of the lapping groove 3. There are a plurality of the first through openings 6, and the plurality of first through openings 6 are arranged at equal distances and of equal size along the long side of the bottom surface of the lapping groove 3. The support plates 5 and the first through openings 6 are in one-to-one correspondence. The support plates 5 penetrate through the first through openings 6. A wheel groove 7 is formed on the bottom surface of the support plate 5. A first limiting shaft 8 is fixed between the two parallel side walls of the wheel groove 7. The pulley 9 is sleeved on the shaft body of the first limiting shaft 8; a side groove 10 is formed on the side plate of the material conveyor 1. A second through opening 11 is formed on the surface of the side groove 10. The second through opening 11 and the first through opening 6 are in one-to-one correspondence, and the second through opening 11 communicates with the first through opening 6. An insertion block 13 penetrates through the second through opening 11 and is inserted into a positioning opening 12. A traction plate 14 is inserted into the side plate of the material conveyor 1. An insertion block 13 is fixed to the surface of the traction plate 14. The insertion block 13 is inserted into the surface of the support plate 5. Three positioning openings 12 are formed on the surface of the support plate 5; when the insertion block 13 is inserted into the upper positioning opening 12, the legs 2 are suspended in the air and the pulley 9 contacts the ground; when the insertion block 13 is inserted into the middle positioning opening 12, the pulley 9 is suspended in the air and the legs 2 contact the ground; when the insertion block 13 is inserted into the bottom positioning opening 12, the support plate 5 is lifted and the legs 2 contact the ground.

[0042] When using the material conveyor 1 to convey ferrous metal smelting materials, it is necessary to support the material conveyor 1 through a plurality of legs 2 to ensure the stable placement of the material conveyor 1; that is, at this time, the insertion block 13 passes through the corresponding second through opening 11 and is inserted into the middle positioning opening 12, that is, the pulley 9 is suspended in the air at this time.

[0043] When the material conveyor 1 needs to be transferred after use, lift the material conveyor 1 from one side of the material conveyor 1. At this time, the legs 2 are suspended in the air. Then, pull the traction plate 14 to drive the insertion block 13 to be pulled out of the middle positioning opening 12. Then, move the support plate 5 downward. Push the traction plate 14 back to drive the insertion block 13 to be inserted into the upper positioning opening 12. At this time, after putting down the material conveyor 1, the pulley 9 contacts the ground. According to the above operation, after adjusting the pulley 9 on the other side to contact the ground and the legs 2 are suspended in the air, the material conveyor 1 can be pushed to slide and transfer; in order to facilitate moving a plurality of support plates 5 simultaneously, the bottom ends of the plurality of support plates 5 are fixed to the surface of a connecting rod 32. In this way, only by pulling the connecting rod 32 can a plurality of support plates 5 be driven to move simultaneously.

[0044] Both ends of the side plate of the material conveyor 1 are provided with sliding grooves 16. A slider 15 is slidably connected inside the sliding groove 16. The slider 15 is in the shape of a "U"-shaped plate. One end of the slider 15 is fixed on the surface of the traction plate 14. A stop block 17 is inserted inside the slider 15, and the stop block 17 is fixed on the surface of the sliding groove 16; a notch 18 is provided on the surface of the traction plate 14, and a rubber belt 19 is fixed on the surface of the notch 18. The rubber belt 19 is in the shape of an "I"-shaped plate structure. Both ends of the rubber belt 19 are fixed on the side plate of the material conveyor 1, and both ends of the rubber belt 19 are respectively distributed on the upper and lower sides of the side groove 10. A handle 20 is fixed on the surface of the traction plate 14, and a reserved groove 31 is provided on the surface of the traction plate 14 for avoiding the servo drive motor installed on the surface of the material conveyor 1.

[0045] The reason for installing the sliders 15 at both ends of the traction plate 14 is that after the sliders 15 slide in the sliding grooves 16, they are limited by the stop blocks 17, so as to prevent the traction plate 14 from being pulled out and falling off the side plate of the material conveyor 1. Moreover, the sliding process of the sliders 15 is greater than the depth of the positioning opening 12. When the traction plate 14 is pulled, the traction plate 14 tenses the rubber belt 19 and deforms. After the traction plate 14 is pushed back and inserted into the side groove 10, the rubber belt 19 rebounds and resets, so as to ensure that the traction plate 14 is inserted into the side groove 10, thereby preventing the insertion block 13 from falling off the positioning opening 12.

[0046] A storage rack 27 is fixed on the surface of the overlapping plate 4. A dust-proof cover one 28 and a dust-proof cover two 29 are fixed inside the storage rack 27. The two dust-proof covers two 29 are connected by a magic tape one. The dust-proof cover one 28 and the side plate of the material conveyor 1 are connected by a magic tape two; a storage groove 21 is provided on the top surface of the overlapping plate 4. There are two storage grooves 21, and the two storage grooves 21 are symmetrically distributed about the center of the top surface of the overlapping plate 4. A limiting shaft two 22 is fixed on the bottom surface of the storage groove 21. The limiting shaft two 22 is in the shape of a "T"-shaped cylinder. The shaft body of the limiting shaft two 22 penetrates through a through hole 23 provided on the surface of the extension plate 33. One end of the extension plate 33 is fixed with a rubber clamping block 26. After the extension plate 33 is folded and stored in the storage groove 21, the rubber clamping block 26 is squeezed between the extension plate 33 and the storage groove 21 to generate elastic deformation. Two screw connection grooves 24 are provided at one end of the extension plate 33 close to the limiting shaft two 22, and the two screw connection grooves 24 are perpendicular. A hand-tightening screw 25 is screwed on the inner wall of the storage rack 27, and one end of the hand-tightening screw 25 is screwed into the screw connection groove 24; the storage rack 27 is in the shape of a "C"-shaped plate structure. One side of each end of the dust-proof cover one 28 is respectively fixed with a magic male tape one and a magic female tape two. One side of each end of the dust-proof cover two 29 is respectively fixed with a magic male tape two and a magic female tape three. A magic female tape one 30 is fixed on the side plate of the material conveyor 1. After the dust-proof cover one 28 is pulled out from the storage rack 27, the magic male tape one and the magic female tape one 30 are cooperatively connected. After the two dust-proof covers two 29 are pulled out, the two dust-proof covers two 29 are stacked vertically and offset. At this time, the magic male tape two and the magic female tape three are cooperatively connected.

[0047] In the process of conveying ferrous metal smelting materials by the material conveyor 1, in order to avoid the diffusion of dust caused by the working bumps of the material conveyor 1, it is necessary to unfold the dust cover 1 28 and the dust cover 2 29 to maintain the upper conveying range of the material conveyor 1; hold the handle 20 to pull the traction plate 14, and the traction plate 14 drives the plug block 13 to be pulled out from the corresponding positioning port 12, and then the connecting rod 32 is moved to drive the multiple support plates 5 to be lifted up until the connecting rod 32 is blocked by the side plate of the material conveyor 1, and then the traction plate 14 is pushed back to be inserted into the side groove 10, and the plug block 13 is inserted into the positioning port 12 at the bottom; The plate 33 rotates ninety degrees with the limiting axis 22 as the center axis, and the hand-tightening screw 25 is screwed into the screw groove 24 to brake the extension plate 33. Then, the two dust covers 29 are pulled out from the two storage racks 27 respectively, and the ends of the two dust covers 29 are offset up and down and stacked. At this time, the Velcro male patch 2 and the Velcro female patch 3 are connected in cooperation, that is, the two dust covers 29 are unfolded to cover the upper part of the material conveyor belt 1. Then, the two dust covers 1 28 are pulled out from the corresponding storage racks 27 respectively, and are connected by the Velcro male patch 1 and the Velcro female patch 1 30. At this time, the dust cover 1 28 is unfolded to cover the side of the material conveyor belt 1.

[0048] When the material conveyor belt 1 is used, the extension plate 33 is pushed back and stored in the storage groove 21, and the lap plate 4 is dropped into the lap groove 3, so that the enclosure structure can be folded and stored; it should be emphasized that the enclosure structure and the bracket are the supporting structure of the sliding transfer material conveyor belt 1, so that one thing can be used for multiple purposes.

[0049] Embodiment 2, based on embodiment 1, proposes a method for using material conveying equipment for ferrous metal smelting, the method comprising the following steps:

[0050] Equipment preparation: Ensure that all parts of the material conveyor 1, such as the legs 2 and the lap plate 4, are in good condition, and store the dust cover 1 28 and the dust cover 2 29 in the storage rack 27 to ensure that they will not interfere with the normal operation of the equipment;

[0051] Equipment start-up: The material conveyor belt machine 1 is supported by multiple legs 2 to ensure that the equipment is placed stably. The plug block 13 should pass through the corresponding through hole 11 and be inserted into the positioning hole 12 in the middle, so that the pulley 9 is suspended in the air to avoid unnecessary movement during the conveying process. The servo drive motor of the material conveyor belt machine 1 is started to start conveying ferrous metal smelting materials;

[0052] Dust prevention measures: During the operation of the equipment, in order to prevent dust diffusion, it is necessary to unfold the dust-proof cover for enclosure. Hold the handle 20 and tension the traction plate 14 to pull out the insertion block 13 from the positioning port 12, and then toggle the connecting rod 32 to drive multiple support plates 5 to lift until the connecting rod 32 is blocked by the side plate of the material conveyor 1. Then, turn out the extension plate 33 from the storage groove 21 and fix it in the screw connection groove 24 by hand-tightening the screw 25 to provide stable support. Then, pull out the dust-proof cover 1 28 and the dust-proof cover 2 29, and connect them to the side plate and the upper and lower sides of the material conveyor 1 respectively through Velcro to form an enclosure structure;

[0053] Stop the equipment operation and fold the dust-proof cover: After the material transportation is completed, turn off the servo drive motor of the material conveyor 1, loosen the hand-tightening screw 25, push the extension plate 33 back into the storage groove 21, separate the Velcro, remove the dust-proof cover 1 28 and the dust-proof cover 2 29 from the enclosure structure, and re-store them in the storage rack 27 to ensure that the dust-proof cover is completely stored without interfering with the subsequent operation of the equipment;

[0054] Equipment sliding transfer: Lift the equipment from one side of the material conveyor 1 to make the support legs 2 suspended, pull the traction plate 14 to drive the insertion block 13 to pull out from the positioning port 12 in the middle, and toggle the support plate 5 downward to make the pulley 9 contact the ground. Repeat the above operation to ensure that the pulley 9 on the other side also contacts the ground, and then push the material conveyor 1 to slide and transfer it to the designated position by using the pulley;

[0055] Equipment parking: After reaching the designated position, place the material conveyor 1 steadily, and by adjusting the positions of the traction plate 14 and the insertion block 13, make the support legs 2 contact the ground again to provide stable support for the equipment. Then, tidy up the sundries around the equipment to ensure that the equipment is in a clean and safe state.

[0056] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
