Description

Technical Field

[0001] This invention belongs to the field of logistics and conveying technology, and in particular relates to a sealing material guiding device for a tape conveyor. Background Technology

[0002] Coal transport lines need to operate continuously to supply energy to downstream equipment. A malfunction causing a shutdown can lead to insufficient material supply, potentially resulting in larger-scale production line shutdowns. During coal transport, some oversized coal pieces may flow downstream during the crushing process. These large pieces can easily clog the transport channels, affecting efficiency. Repair work is not only time-consuming and labor-intensive but also exposes personnel to additional safety risks. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, the present invention provides a sealed material guiding device for belt conveyors that can process large pieces of coal online.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A sealing and guiding device for a tape conveyor includes a material collecting section and a material guiding section connected in sequence. The material collecting section has an inlet at its upstream end and an outlet at its downstream end. The outlet is configured to correspond to the position of the conveyor line. The material guiding section includes a feeding channel 4 and a crushing component movably disposed within the feeding channel. A window is provided on the side of the feeding channel, and the moving path of the crushing component 5 passes through the material conveying path within the feeding channel and reaches the window.

[0005] In a preferred embodiment, the material crushing assembly includes a connector, a guide, and a hammer. One end of the connector is movably connected to the material guide, and the other end is connected to the guide. The guide is positioned with a first end near the window and a second end away from the window. The hammer is slidably fitted onto the first end of the guide. A limiting member is provided on the guide to restrict the sliding stroke of the hammer as it slides along the guide. When the hammer slides along the guide to contact the limiting member, the first end of the guide protrudes beyond the hammer.

[0006] As a preferred embodiment, the first end of the guide member is provided with a splitting body, which includes a plurality of blades extending in a straight line, with a loosening gap between adjacent blades.

[0007] As a preferred embodiment, the splitting body has a flat structure, the thickness of the splitting body gradually increases along the direction away from the blade edge, and the length of the splitting body is less than the sliding stroke of the hammer on the guide member.

[0008] In a preferred embodiment, the connector is hinged inside the guide section, which can drive the guide and the hammer to swing. The connector is connected to the second end of the guide. The connector includes a driver, a first rod, and a second rod. The driver drives the first rod to swing along the hinge. One end of the second rod is connected to the first rod, and the other end is connected to the guide. A first connection position and a second connection position are provided between the first rod and the second rod. When the second rod is in the first connection position, the first rod and the second rod are rigidly connected. When the second rod is in the second connection position, the first rod and the second rod are flexibly connected.

[0009] In a preferred embodiment, the first rod has a cavity formed at one end near the second rod, and the second rod has a position adjustment body at one end near the first rod. The position adjustment body includes a movable block and an adsorption block connected to each other. The movable body is fitted inside the cavity. The movable block has a spherical structure and can slide relative to the inner wall of the cavity. An electromagnetic adsorption platform is provided outside the cavity. The electromagnetic adsorption platform cooperates with the adsorption block. The cavity has an opening to accommodate the displacement of the connection between the movable block and the adsorption block. When the adsorption block is adsorbed onto the electromagnetic adsorption stage, the movable block separates from the inner wall of the cavity, and the second rod is located at the first connection position; when the adsorption block separates from the electromagnetic adsorption stage, the movable block contacts the inner wall of the cavity, and the second rod is located at the second connection position.

[0010] As a preferred embodiment, the feeding channel extends in an arc shape along its length, and the angle between the discharge direction of the feeding channel at the discharge port and the conveying direction of the conveyor line is less than 15°.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The sealing and guiding device for conveyor belts described in this invention comprises a material collection section and a material guiding section connected in sequence. The material collection section has an inlet at its upstream end, and the material guiding section has an outlet at its downstream end. The outlet is configured to correspond to the position of the conveyor line. The material guiding section includes a feeding channel and a crushing component movably disposed within the feeding channel. A window is provided on the side of the feeding channel, and the moving path of the crushing component passes through the material conveying path within the feeding channel and reaches the window. The function of the crushing component is to impact larger pieces of coal inside the feeding channel through its own movement, breaking them into smaller pieces. These smaller pieces of coal are pushed out of the feeding channel through the window by the crushing component, thus solving the space blockage problem caused by large pieces of coal. This not only achieves the effect of clearing larger pieces of coal and unblocking the conveyor line, but also reduces the power and other equipment parameter requirements of the crushing component components, thereby effectively controlling equipment costs and achieving significant cost reduction. This facilitates the low-cost transformation of the entire conveyor line and promotes the implementation and application of this technology. Attached Figure Description

[0017] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0018] In the description of this invention, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on the invention. Furthermore, "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0019] Please see Figure 1 and Figure 2 As shown, this embodiment of the invention provides a sealing and guiding device for a tape conveyor, specifically including a material collecting section 1 and a material guiding section 2 connected sequentially. The material collecting section 1 has an inlet 101 at its upstream end, and the material guiding section 2 has an outlet 201 at its downstream end. The outlet 201 is configured to correspond to the position of the conveyor line 3. The material guiding section 2 includes a feeding channel 4 and a crushing component 5 movably disposed within the feeding channel 4. A window 41 is provided on the side of the feeding channel 4, and the moving path of the crushing component 5 passes through the material conveying path within the feeding channel 4 and reaches the window 41.

[0020] Specifically, in this embodiment, when transporting coal, the coal that has been broken into chunks upstream enters the sealed guiding device through the inlet 101. This coal passes sequentially through the collecting section 1 and the guiding section 2, and finally is transferred from the outlet 201 to the conveyor line 3, which includes a belt conveyor, i.e., a conveyor belt machine. Because the coal entering the sealed guiding device contains some large pieces that have not been sufficiently broken up, it can cause blockages in the channels of the guiding section 2 and other conveyor lines. This can affect the overall transport efficiency of the conveyor line, or cause the conveyor belt to tilt and cause coal to fall off, which can lead to contamination of the conveying equipment and an increased failure rate.

[0021] In this embodiment, the crushing component 5 functions by impacting larger pieces of coal inside the feeding channel 4 through its own movement, breaking them into smaller pieces. These smaller pieces are then pushed out of the feeding channel 41 through the window 41 by the crushing component 5, thus resolving the space blockage problem caused by the large pieces of coal. Furthermore, as a complementary measure, a recycling container can be arranged outside the feeding channel 4, below the window 41, to collect the discharged coal. A return conveyor line can be further installed to send any remaining large pieces of coal back to the upstream crushing equipment for re-crushing, achieving high-efficiency material utilization and reducing losses. This two-step cleaning process effectively removes larger pieces of coal, unblocks the transport line, and reduces the power and other equipment parameter requirements of the crushing component 5, thereby effectively controlling equipment costs and achieving significant cost reduction. This results in a low-cost overall transformation of the transport line, facilitating the implementation and application of this technology.

[0022] The movement of the crushing component 5 can take various forms, such as telescopic or swinging. It can be driven by electric or hydraulic means. The kinetic energy generated by the movement is used to contact and impact large pieces of coal to achieve the purpose of initially crushing the larger pieces of coal. The movement then pushes the smaller pieces of coal obtained from the crushing away from the feeding channel 4.

[0023] Please see Figures 3 to 5 As shown, the crushing assembly 5 specifically includes a connector 51, a guide 52, and a hammer 53. One end of the connector 51 is movably connected to the guide section 2, and the other end is connected to the guide 52. The end of the guide 52 closer to the window 41 is designated as the first end, and the end farther from the window 41 is designated as the second end. The hammer 53 is slidably fitted onto the first end of the guide 52. A limiting member 521 is provided on the guide 52 to limit the sliding stroke of the hammer 53 when it slides along the guide 52. When the hammer 53 slides along the guide 52 to contact the limiting member 521, the first end of the guide 52 protrudes from the hammer 53. Specifically, in this embodiment, when the crushing component 5 first contacts a larger piece of coal, the front end of the guide member 52 will pierce and embed itself into the surface of the coal, and its movement will slow down or stop due to the obstruction of the coal. At the same time, the heavier hammer 53 will slide relative to the guide member 52 under the action of inertia, and impact the coal to release kinetic energy during this relative sliding. This impact will create stress concentration at the piercing point of the guide member 52, making it easy for the coal to crack into multiple smaller pieces. Through the two-stage cooperation of the guide member 52 and the hammer 53, the crushing effect on the coal can be greatly improved. In addition, some sliding damping can be set between the guide member 52 and the hammer 53, so that the two maintain a fixed relative position during the movement before the impact, and then slide relative to each other after the impact, realizing the above-mentioned two-stage cooperation of piercing and impact. The limiting member 521, as shown in the figure, can be a pin inserted into the guide member 51.

[0024] In this embodiment, an elastic element is provided between the hammer 53 and the connecting member 51 to allow the hammer 53 to reset under tension after impacting the coal, and to prevent the hammer 53 from sliding too far and separating from the guide member 52. A counterweight can also be provided at the second end of the guide member 52 to enhance the piercing kinetic energy of the connecting member 51. By matching the weight with the hammer 53, the optimal two-stage crushing effect can be achieved.

[0025] Please see Figure 5 As shown, the first end of the guide member 52 is provided with a splitting body 522, which includes multiple blades 523 extending in a straight line, with a loosening gap 524 between adjacent blades 523. The inclined splitting body 522 serves as the part that embeds into the coal after piercing. This blade shape, which is thinner at the front end and thicker at the rear end, allows for easier increase of local pressure in the initial piercing stage, thus facilitating successful embedding into the coal. On the other hand, it can create outward compressive force within the coal's fracture as it continues to penetrate the coal, promoting coal splitting. The feeding gap 524 between the blades 523 avoids excessively wide single blade sections. This not only reduces maintenance costs by partially replacing individual blades 523, but also utilizes the space of the feeding gap 524 to create a locking and anti-slip effect on the coal, improving the success rate of material breaking.

[0026] Please see Figure 4 and Figure 5 As shown, the chopping body 522 has a flat structure, and its thickness gradually increases along the direction away from the blade edge. The length of the chopping body 522 is less than the sliding stroke of the hammer 53 on the guide member 52. In actual assembly, the front end of the chopping body 522 can be made of a material with higher hardness, such as manganese steel, as the scraper 523, which can significantly extend the service life of the material crushing assembly 5. The length of the chopping body 522 is set to be less than the sliding stroke of the hammer 53 on the guide member 52 so that the hammer 53 can cover and enclose the chopping body 522, thereby protecting the chopping body 522 in non-impact conditions.

[0027] Please see Figure 3As shown, the connector 51 is hinged inside the guide section 2, and can drive the guide 52 and the hammer 53 to swing. The connector 51 is connected to the second end of the guide 52. The connector 51 includes a driver 510, a first rod 511, and a second rod 512. The driver 510 drives the first rod 511 to swing along the hinged portion. One end of the second rod 512 is connected to the first rod 511, and the other end is connected to the guide 52. A first connection position and a second connection position are provided between the first rod 511 and the second rod 512. When the second rod 512 is in the first connection position, the first rod 511 and the second rod 512 are rigidly connected. When the second rod 512 is in the second connection position, the first rod 511 and the second rod 512 are flexibly connected.

[0028] In this embodiment, by setting the connector 51 as a two-section structure, on the one hand, the flexible connection between the first rod 511 and the second rod 512 can be used to avoid the rigid transmission of collision vibration, thereby protecting the driver 510 and the hinged part from damage. On the other hand, when the guide 51 or the hammer 52 fails to complete the crushing and encounters obstruction, the force can be unloaded by the relative angle change at the flexible connection, which also plays a protective role for the crushing component 5.

[0029] Please see Figure 5 and Figure 6 As shown, a chamber 514 is formed at one end of the first rod 511 near the second rod 512, and a position adjustment body 515 is provided at one end of the second rod 512 near the first rod 511. The position adjustment body 515 includes a movable block 501 and an adsorption block 502 connected to each other. The movable body 501 is fitted inside the chamber 514. The movable block 501 has a spherical structure and can slide relative to the inner wall of the chamber 514 when in contact with it. An electromagnetic adsorption platform 516 is provided outside the chamber 514. The electromagnetic adsorption platform 516 cooperates with the adsorption block 501. The chamber 514 has an opening to accommodate the displacement of the connection between the movable block 501 and the adsorption block 502. When the adsorption block 501 is adsorbed onto the electromagnetic adsorption platform 516, the movable block 501 separates from the inner wall of the chamber 514, and the second rod 512 is located at the first connection position. When the adsorption block 501 separates from the electromagnetic adsorption platform 516, the movable block 501 contacts the inner wall of the chamber 514, and the second rod 512 is located at the second connection position.

[0030] In this embodiment, the position adjustment body 515 allows the first rod 511 and the second rod 512 to switch between a rigid connection state and a flexible connection state. During the initial swing around the hinge, before the material crushing assembly 5 comes into contact with the coal, the electromagnetic adsorption platform 516 is energized to engage the adsorption block 501, maintaining a rigid connection between the first rod 511 and the second rod 512, thus enabling synchronous acceleration to increase kinetic energy. When the connecting member 51 swings past a specific angle and is about to collide with the coal, the electromagnetic adsorption platform 516 is de-energized and separates from the adsorption block 501. At this point, the first rod 511 and the second rod 512 are flexibly connected, significantly reducing vibration transmission during subsequent impacts and crushing, protecting the driver and the connection point. The aforementioned energization / de-energization switching can be controlled by a PLC switch in conjunction with a oscillation angle detection sensor such as a digital unit.

[0031] Please see Figure 2 As shown, the feeding channel 4 extends in an arc shape along its length. The angle between the discharge direction of the feeding channel 4 at the discharge port 201 and the conveying direction of the conveyor line 3 is less than 15°. The left arrow in the figure indicates the discharge direction, at which point the angle between the discharge direction and the conveying direction (horizontal direction) of the conveyor line is 0°. In other embodiments, other angles such as 1°, 3°, 7°, 10°, 12°, and 15° can also be used. By controlling the angle within a certain range, problems such as splashing and dust caused by coal falling can be reduced. In this embodiment, a machine cover 6 is also included. The machine cover 6 is installed outside the material collection section 1 and the material guiding section 2, and the machine cover 6 is provided with an exhaust dust removal hole. The function of the machine cover 6 is to prevent some dust from overflowing, improve the production environment, and at the same time reserve an interface for exhaust dust removal equipment for future upgrades and modifications.

[0032] Please see Figure 1 and Figure 3 As shown, the crushing component 5 is configured to move along the length of the feeding channel 4, and multiple windows 41 are provided along the length of the feeding channel 4. The slide rail 50 in the figure can slide and engage with the upper end of the connecting piece 51, thereby allowing the working position of the crushing component 5 to move within the feeding channel 4. The preferred working position of the crushing component 5 in the feeding channel 4 shown in the figure is near the discharge port 201 at the lower end of the guide section 2. At this location, the feeding channel 4 loses the aid of the inclined ramp, and larger pieces of coal are most likely to accumulate and cause blockages. The collecting section 1 is a vertically arranged bucket structure, and a vibration component is provided on the collecting section 1. The vibration component can reduce dust adhesion to the inner wall and also facilitates the uniform distribution of coal within the feeding channel 4, improving space utilization.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
