Description

Technical Field

[0001] The present application relates to the technical field of coal transportation, and in particular to a transportation device. Background Art

[0002] In industrial production processes that use coal as fuel, it is usually necessary to transport the coal to the desired location through a conveying device. The coal transported by the conveying device often includes various forms such as powder, granular and lumps. The materials transported by the conveying device have the characteristics of high humidity, high ash content and high viscosity. Therefore, during the transportation process, it is easy for the materials to adhere to the silo wall of the conveying device or get blocked in containers such as silos or hoppers, causing flow interruption and reducing the coal transportation efficiency.

[0003] Therefore, it is necessary to provide a conveying device to improve the conveying efficiency of coal. Utility Model Content

[0004] Based on the above-mentioned deficiencies, the present application provides a conveying device to partially or completely improve the problem of low conveying efficiency in the related art.

[0005] This application is implemented as follows:

[0006] The example of the present application provides a conveying device, including a conveying mechanism and a pushing mechanism. The conveying mechanism includes a first hopper, and the side wall of the first hopper has a connecting portion; the pushing mechanism includes a driving assembly, a first ramming rod and a second ramming rod, and the driving assembly is arranged at the connecting portion; the first ramming rod has a spiral ramming section extending along its axial direction, and the second ramming rod has a broken line ramming section extending along its axial direction; the first ramming rod and the second ramming rod are arranged at intervals and are both connected to the driving assembly; the driving assembly is used to independently drive the first ramming rod and the second ramming rod to move, so as to ram the material in the first hopper downward.

[0007] In the above implementation process, a driving assembly is provided at the side wall of the first hopper, and the driving assembly can independently drive the first pounding rod and the second pounding rod to move. Since the first pounding rod has a spiral pounding section extending along its axial direction, and the second pounding rod has a zigzag pounding section extending along its axial direction, the movement of the two pounding sections of different shapes can be used to pound the material in the first hopper downward, thereby reducing the probability of coal flow interruption and improving the coal transportation efficiency. In addition, since the pounding mechanism has pounding rods with two pounding sections of different shapes, the spiral pounding section and the zigzag pounding section pound the material at the same time, which can cause the material to form turbulent flow, reduce the probability of coal adhering to the pounding section, and further improve the coal transportation efficiency.

[0008] In combination with the first aspect, in an optional implementation, a rounded corner is provided between two adjacent fold line segments of the fold line tamping segment.

[0009] In the above implementation process, providing a rounded corner between two adjacent zigzag segments of the zigzag tamping segment can alleviate the stress concentration phenomenon of the zigzag tamping segment, increase the service life of the second tamping rod, and reduce the probability of coal getting stuck between the zigzag segments.

[0010] In combination with the first aspect, in an optional embodiment, the conveying mechanism also includes a distribution hopper, the axis of which is parallel to the axis of the first hopper; the circumferential side wall of the first hopper is provided with a first opening, and the first opening is located below the connecting part; the entrance of the distribution hopper fits with the first opening; the driving assembly is used to drive the first pounding rod and the second pounding rod to move, so as to pound the material at the first opening downward and convey it into the distribution hopper.

[0011] In the above implementation process, a sub-hopper is also provided in the conveying mechanism, and the inlet of the sub-hopper is matched with the first opening of the first hopper, and part of the coal conveyed into the first hopper can flow into the sub-hopper from the first opening to convey the coal in a divided way. Since the first opening is located below the connecting part, the driving assembly provided at the connecting part can drive the first ramming rod and the second ramming rod to move, so as to promote the coal at the first opening below the connecting part to flow into the sub-hopper, thereby improving the conveying efficiency of the sub-hopper.

[0012] In combination with the first aspect, in an optional embodiment, the drive assembly is used to independently drive the first ramming rod and the second ramming rod to telescopically move.

[0013] In the above implementation process, the driving assembly drives the first tamping rod and the second tamping rod to telescopically move, and the first tamping rod and the second tamping rod tamp the coal up and down during the telescopic movement, thereby improving the coal transportation efficiency.

[0014] In combination with the first aspect, in an optional embodiment, the driving assembly includes multiple groups of cylinders, the fixed ends of the multiple groups of cylinders are spaced apart at the connecting portion, and the output ends of the multiple groups of cylinders are connected to the first ramming rod and the second ramming rod in a one-to-one correspondence.

[0015] In the above implementation process, the fixed end of the cylinder is arranged at the connecting part, and the telescopic movement of the output end of the cylinder can be used to drive the telescopic movement of the first ramming rod and the second ramming rod, thereby improving the coal transportation efficiency.

[0016] In combination with the first aspect, in an optional embodiment, the connecting part is provided with a plurality of second openings, the plurality of second openings are arranged at intervals, a connecting block is provided on the edge of the connecting part corresponding to each second opening, the fixed end of the cylinder passes through the second opening and extends out of the first hopper, and the fixed end of the cylinder is connected to the connecting part through the connecting block.

[0017] In the above implementation process, a plurality of second openings are provided at the connection part, and the fixed end of the cylinder can be extended out of the first hopper through the second opening, which can avoid the fixed end of the cylinder being located in the first hopper and affecting the coal transportation. In addition, the fixed end of the cylinder is connected to the connection part through a connection block, which can avoid the connection stability of the cylinder being affected by the thin wall of the first hopper.

[0018] In combination with the first aspect, in an optional implementation, each second opening is covered with a dust cover, and the top of the dust cover is configured as a downwardly inclined slope; the cylinder cover is disposed in the dust cover.

[0019] In the above implementation process, a dust cover is provided at each opening, and the cylinder cover is provided inside the dust cover, which can reduce the influence of coal on the movement process of the cylinder and improve the stability and service life of the pushing mechanism. In addition, the top of the dust cover is provided as a downward inclined surface, and the coal on the top of the dust cover can flow downward along the inclined surface of the top of the dust cover, thereby reducing the degree of obstruction of the dust cover to the coal transportation.

[0020] In combination with the first aspect, in an optional embodiment, the drive assembly is used to independently drive the first tamping rod and the second tamping rod to rotate.

[0021] In the above implementation process, the driving assembly drives the first pounding rod and the second pounding rod to rotate.

[0036] Due to the characteristics of coal such as high humidity, high ash content and high viscosity, during the transportation process of coal, the coal is easy to adhere to the silo wall or get stuck in containers such as silos or hoppers, causing flow interruption and reducing the transportation efficiency of coal.

[0037] Therefore, the present application provides a conveying device 1, which can improve the coal conveying efficiency to a certain extent. In order to make the purpose, technical solution and advantages of the embodiment of the present application clearer, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application.

[0038] See also Figure 1 An embodiment of the present application provides a conveying device 1, including a conveying mechanism 10 and a pushing mechanism 20.

[0039] Please continue to read Figure 1 The conveying mechanism 10 includes a first hopper 11 , and a side wall of the first hopper 11 has a connecting portion 111 .

[0040] Among them, see Figure 2The pushing mechanism 20 includes a driving assembly 21, a first ramming rod 22, and a second ramming rod 23. The driving assembly 21 is arranged at the connecting portion 111; the first ramming rod 22 has a spiral ramming section 221 extending along its axial direction, and the second ramming rod 23 has a broken line ramming section 231 extending along its axial direction; the first ramming rod 22 and the second ramming rod 23 are arranged at intervals and are both connected to the driving assembly 21. The driving assembly 21 is used to independently drive the first ramming rod 22 and the second ramming rod 23 to move, so as to ram the material in the first hopper 11 downward.

[0041] A pushing mechanism 20 is provided in the conveying device 1. The first ramming rod 22 and the second ramming rod 23 in the pushing mechanism 20 can move under the drive of the driving assembly 21, thereby improving the fluidity of the coal in the first hopper 11, reducing the probability of the coal adhering to the inner wall of the hopper, and improving the coal conveying efficiency.

[0042] In addition, the pushing mechanism 20 is provided with a first pounding rod 22 having a spiral pounding section 221 and a second pounding rod 23 having a zigzag pounding section 231. The spiral pounding section 221 and the zigzag pounding section 231 have different shapes and structures. The spiral pounding section 221 and the zigzag pounding section 231 are driven by the driving assembly 21 to move, which can disturb the coal, not only improve the fluidity of the coal, but also reduce the probability of the coal adhering to the first pounding rod 22 and the second pounding rod 23, thereby improving the conveying efficiency. The first pounding rod 22 and the second pounding rod 23 are provided, and the coal can also be pounded when one of the pounding rods cannot work effectively.

[0043] If the pushing mechanism 20 is only provided with the first ramming rod 22 or the second ramming rod 23, the pushing mechanism 20 pushes the coal to move in a relatively single direction, and the coal is easy to move with the ramming rod and then adhere to the ramming rod, thus affecting the coal conveying efficiency.

[0044] The conveying mechanism 10 and the pushing mechanism 20 in the conveying device 1 of the present application are further described in detail below in conjunction with the accompanying drawings.

[0045] Please continue reading Figure 1 and Figure 2 The conveying mechanism 10 has a first hopper 11 for conveying coal. The first hopper 11 has a feed inlet 112 and a discharge inlet 113 , and a side wall between the feed inlet 112 and the discharge inlet 113 .

[0046] In some possible embodiments, the first material head 11 may be funnel-shaped, the cross-sections of the feed port 112 and the discharge port 113 are circular, and the feed port 112 is located above the discharge port 113 .

[0047] Further, in some possible embodiments, please continue to refer to Figures and Figure 2The conveying mechanism 10 may also be provided with a sub-hopper 12. A first opening 114 is provided at the side wall of the first hopper 11, and the inlet of the sub-hopper 12 fits with the first opening 114, so that the first hopper 11 and the sub-hopper 12 are connected.

[0048] When the conveying mechanism 10 is used to convey coal, the coal enters from the feed port 112 of the first hopper 11, a portion of the coal in the first hopper 11 is delivered from the discharge port 113 of the first hopper 11, and another portion enters the sub-hopper 12 from the first opening 114 and is delivered from the sub-hopper 12. The first hopper 11 and the sub-hopper 12 can realize multi-path conveyance of the coal.

[0049] For some possible embodiments, please refer to Figure 1 The distribution hopper 12 is funnel-shaped, and the axis of the distribution hopper 12 is parallel to the axis of the first hopper 11.

[0050] Exemplarily, the sub-hopper 12 and the first hopper 11 are both arranged vertically.

[0051] Exemplarily, the feed inlet of the distribution hopper 12 is located on the side wall thereof.

[0052] Further, in some possible embodiments, please continue to refer to Figure 1 and Figure 2 The conveying mechanism 10 is also provided with a first feeder 13, and the first feeder 13 is connected to the discharge port 113 of the first hopper 11, so that the first feeder 13 can be used to feed materials to the rear-end material-using equipment.

[0053] The present application does not limit the specific type of the first feeder 13. In some possible embodiments, the first feeder 13 can be selected from a traditional belt conveyor or a scraper conveyor, etc., and its structure is well known to those skilled in the art, and its description is omitted here.

[0054] Further, in some possible embodiments, please continue to refer to Figure 1 The conveying mechanism 10 may also be provided with a second feeder 14, and the discharge port of the sub-hopper 12 is connected to the feed port of the second feeder 14, so that the second feeder 14 can be used to feed materials to the rear-end material-using equipment.

[0055] For further information, please refer to Figure 1 The conveying mechanism 10 may also be provided with a second hopper 15 , and the discharge port of the second hopper 15 is connected to the feed port of the second feeder 14 .

[0056] The discharge port of the sub-hopper 12 and the discharge port of the second hopper 15 are connected to the feed port of the second feeder 14, so that the coal in the first hopper 11 and the coal in the second hopper 15 can be compounded, and the compounded mixed coal can be transported to the rear-end material equipment by the second feeder 14.

[0057] See also Figure 2 and Figure 3 The pushing mechanism 20 includes a driving assembly 21, a first ramming rod 22 and a second ramming rod 23. The driving assembly 21 drives the first ramming rod 22 and the second ramming rod 23 to move, so as to ram the coal in the first hopper 11 downward, thereby improving the coal transportation efficiency.

[0058] The first tamping rod 22 has a spiral tamping section 221 , and the spiral tamping section 221 extends along the axial direction of the first tamping rod 22 .

[0059] Exemplarily, the first pounding rod 22 further has a connecting section connected to the spiral pounding section 221 , the connecting section is rod-shaped, and the extending direction of the spiral pounding section 221 is consistent with the axial direction of the connecting section.

[0060] The connecting portion 111 is located on the side wall of the first hopper 11, and the side wall of the funnel-shaped first hopper 11 is an inclined surface. The driving assembly 21 is arranged on the connecting portion 111 of the side wall of the first hopper 11. In order to facilitate the use of the driving assembly 21 to drive the first pounding rod 22 to move and pound the coal in the first hopper 11 downward, illustratively, the axial direction of the first pounding rod 22 extends obliquely downward along the inclined direction of the connecting portion 111.

[0061] Furthermore, the end of the spiral pounding section 221 away from the connecting section is conical.

[0062] The second tamping rod 23 has a broken-line tamping section 231 , and the broken-line tamping section 231 extends along the axial direction of the second tamping rod 23 .

[0063] Exemplarily, the second tamping rod 23 further has a connecting section connected to the broken line tamping section 231 , the connecting section is rod-shaped, and the extending direction of the broken line tamping section 231 is consistent with the axial direction of the connecting section.

[0064] The connecting portion 111 is located on the side wall of the first hopper 11, and the side wall of the funnel-shaped first hopper 11 is an inclined surface. The driving assembly 21 is disposed on the connecting portion 111 of the side wall of the first hopper 11. In order to facilitate the use of the driving assembly 21 to drive the second ramming rod 23 to move and ram the coal in the first hopper 11 downward, illustratively, the axial direction of the second ramming rod 23 extends obliquely downward along the inclined direction of the connecting portion 111.

[0065] Furthermore, the end of the broken-line tamping section 231 away from the connecting section is conical.

[0066] Furthermore, rounded corners are provided between the folded line segments of the folded line tamping segment 231 .

[0067] Since a first opening 114 is provided below the connection portion 111 , the driving assembly 21 provided at the connection portion 111 can drive the first pounding rod 22 and the second pounding rod 23 to move, so as to pound the material at the first opening 114 into the distribution hopper 12 , thereby improving the conveying efficiency of the material at the distribution hopper 12 .

[0068] Furthermore, the present application does not limit how the drive assembly 21 drives the first ramming rod 22 and the second ramming rod 23 to move. Relevant personnel can make relevant choices while ensuring that the drive assembly 21 can drive the first ramming rod 22 and the second ramming rod 23 to move the coal in the first hopper 11 downward.

[0069] In some possible embodiments, the driving assembly 21 drives the first tamping rod 22 and the second tamping rod 23 to telescope.

[0070] Since the first pounding rod 22 and the second pounding rod 23 are arranged to be tilted downward, the spiral pounding segment 221 and the broken line pounding segment 231 will exert force on the material during the expansion and contraction process, thereby promoting the flow of the material and improving the conveying efficiency of the material.

[0071] Furthermore, in a possible embodiment, the driving assembly 21 includes multiple groups of cylinders 211, the fixed ends of the multiple groups of cylinders 211 are spaced apart at the connecting portion 111, and the output ends of the multiple groups of cylinders 211 are connected to the first pounding rod 22 and the second pounding rod 23 one by one.

[0072] Further, in order to facilitate fixing the fixed end of the cylinder 211 to the connecting portion 111, in a possible embodiment, please continue to refer to Figure 3 and Figure 3 A connecting block 24 may be provided, and the cylinder 211 is connected to the connecting portion 111 via the connecting block 24 .

[0073] Since the side wall of the first hopper 11 is usually thin, if the fixed end of the cylinder 211 is directly fixed to the connecting portion 111, it is easy to cause the connecting portion 111 of the first hopper 11 to deform or cause the cylinder 211 to be unstable, affecting the stability of the conveying device 1. The cylinder 211 is connected to the connecting portion 111 through the connecting block 24, and the connecting block 24 can increase the strength of the connecting portion 111 and improve the connection stability of the cylinder 211.

[0074] Exemplarily, connection blocks 24 may be provided at both the inner wall and the outer wall of the first hopper 11 corresponding to the connection portion 111, and the two connection blocks 24 clamp the connection portion 111 therebetween.

[0075] Further, in order to reduce the obstruction of the fixed end of the cylinder 211 on the material conveying, in a possible embodiment, please continue to refer to Figure 2 and Figure 3 ( Figure 2 and Figure 3 In order to conveniently display the second opening 115, the dust cover at the third ramming rod 27 is removed, and the connecting portion 111 is provided with a plurality of second openings 115, and the plurality of second openings 115 are arranged at intervals. The fixed end of the cylinder 211 extends out of the first hopper 11 through the second opening 115, and the fixed end of the cylinder 211 is connected to the connecting portion 111 through the connecting block 24.

[0076] The fixed end of the cylinder 211 extends out of the first hopper 11 through the second opening 115 . The fixed end of the cylinder 211 may be partially or completely located outside the first hopper 11 .

[0077] The fixed end of the cylinder 211 is extended outside the first hopper 11 through the second opening 115, so that the structure of the cylinder 211 in the first hopper 11 is less, and the space occupancy rate of the cylinder 211 in the first hopper 11 is reduced, thereby reducing the obstruction of the cylinder 211 to material transportation and improving the material transportation efficiency.

[0078] Furthermore, the output end of the cylinder 211 may be connected to the first ramming rod 22 or the second ramming rod 23 via a pin.

[0079] Exemplarily, a U-shaped groove may be provided at the output end of the cylinder 211, a protrusion capable of extending into the U-shaped groove may be provided at the connecting end of the first ramming rod 22 or the second ramming rod 23, and a pin may pass through the protrusion and the U-shaped groove.

[0080] Furthermore, a clamping ring may be provided at the connecting portion 111 , and the first ramming rod 22 or the second ramming rod 23 passes through the clamping ring and is connected to the U-shaped groove at the output end of the cylinder 211 .

[0081] Further, in order to protect the cylinder 211 and improve the connection stability between the cylinder 211 and the first ramming rod 22 or the second ramming rod 23, in a possible embodiment, please continue to refer to Figure 2 and Figure 3 A dust cover 26 may be provided at each second opening 115 , and the dust cover 26 covers the cylinder 211 and part of the first ramming rod 22 or the second ramming rod 23 inside the dust cover 26 , so as to prevent the material in the first hopper 11 from getting stuck in the cylinder 211 and the connection between the cylinder 211 and the first ramming rod 22 or the second ramming rod 23 .

[0082] For example, an opening may be provided at the bottom end of the dust cover 26 to facilitate the spiral pounding section 221 of the first pounding rod 22 or the broken line pounding section 231 of the second pounding rod 23 to pass through the dust cover 26 for pounding.

[0083] Furthermore, in order to reduce the obstruction of the dust cover 26 to the material transportation in the first hopper 11, in a possible embodiment, the top of the dust cover 26 can be set as a downward inclined surface so that the material on the top of the dust cover 26 can flow downward along the bottom.

[0084] Alternatively, in some possible embodiments, the driving assembly 21 drives the first tamping rod 22 and the second tamping rod 23 to rotate.

[0085] Since the first pounding rod 22 and the second pounding rod 23 are arranged to be tilted downward, the spiral pounding segment 221 and the broken line pounding segment 231 will exert force on the material during the rotational movement, promote the flow of the material, and thus improve the conveying efficiency of the material.

[0086] In a possible embodiment, the driving assembly 21 includes a plurality of rotary motors (not shown in the figure), and the plurality of rotary motors are used to drive the first tamping rod 22 and the second tamping rod 23 to rotate in a one-to-one correspondence to tamping the material.

[0087] The fixing method of the rotating motor can be the same as the fixing method of the cylinder 211, which will not be repeated here.

[0088] Alternatively, in some possible embodiments, the drive assembly 21 drives the first ramming rod 22 to telescopically move, and the drive assembly 21 drives the second ramming rod 23 to rotate, so as to further reduce the probability of material adhering to the ramming rod, improve the fluidity of the material, and improve the conveying efficiency.

[0089] For further information, please refer to Figure 2 and Figure 3 The pushing mechanism 20 may further be provided with a third ramming rod 27 , and the ramming section of the third ramming rod 27 is different from the spiral ramming section 221 and the broken line ramming section 231 .

[0090] The pounding section of the third pounding rod 27 is different from the spiral pounding section 221 and the zigzag pounding section 231. It can be a pounding section with a bending direction different from that of the zigzag pounding section 231, a pounding section with a spiral size different from that of the spiral pounding section 221, or a wavy pounding section.

[0091] The movement mode of the third ramming rod 27 and the connection mode with the driving assembly 21 may be the same as those of the first ramming rod 22 or the second ramming rod 23, and will not be described in detail herein.

[0092] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
