Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a coal conveying belt trough. Background Art

[0002] The coal conveyor belt trough is an inclined trough structure used to receive coal blocks and transfer them downstream.

[0003] When the belt trough receives coal blocks, it is subject to the impact of the coal blocks falling onto the bottom of the belt trough, as well as the wear of the coal blocks sliding on the bottom of the belt trough. When the belt trough is used for a long time, the bottom plate of the trough may be damaged and coal may leak. The leaked coal blocks not only pollute the workshop environment, but also require the staff to perform additional operations to collect the leaked coal blocks. In addition, during non-overhaul periods, since replacing the trough takes a long time and affects the normal production of the production line, the conventional treatment method for leakage of the trough bottom plate is mostly to use hot-fire welding to eliminate the leak. However, the actual situation is that after one leak is repaired by welding, leaks occur again in other places, which not only further increases the workload, but the frequent hot-fire operations on site also increase the risk of hidden dangers.

[0004] Although the existing technology can improve the strength and wear resistance of belt chutes by increasing the thickness of the trough bottom plate, or by providing a wear-resistant layer on the bottom surface of the trough, as described in the text of the Chinese patent publication number CN107672254A entitled "A Wear-Resistant and Shock-Reducing Belt Chute", in actual implementation, increasing the thickness of the trough bottom plate will lead to an excessive increase in the overall weight of the belt trough, increasing the load-bearing requirements of the lower part of the belt trough. In addition, when the belt trough is installed at a high position, it also significantly increases the difficulty of installation. If the wear-resistant layer is provided with a small thickness, it will easily wear off and fall off, which has little effect on the wear resistance. If the wear-resistant layer is thicker, it will increase the overall weight of the belt chute excessively, similar to increasing the thickness of the trough bottom plate. In addition, the provision of a wear-resistant layer does not significantly improve the overall strength of the belt chute, and its resistance to coal block impact is average. It is often necessary to provide a buffer layer to cushion the impact of coal blocks, which undoubtedly further increases the overall weight of the belt chute, and therefore needs to be solved urgently. Utility Model Content

[0005] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a coal conveying belt trough, which improves the service life of the belt trough without increasing the weight of the belt trough too much.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A coal conveyor belt trough includes a feeding trough, the bottom of the feeding trough is provided with reinforcing steel bars connecting the trough walls on both sides of the feeding trough, the bottom of the feeding trough is provided with a slag feeding trough arranged along the length of the feeding trough, the reinforcing steel bars are arranged to be distributed at intervals along the length of the feeding trough and cover the entire feeding trough, and adjacent reinforcing steel bars and the bottom of the feeding trough are enclosed to form a diversion trough for discharging coal slag to the slag feeding trough.

[0008] As a further solution of the present invention: from the perspective of the length direction of the feeding trough, the bottom of the feeding trough is inclined, and the slot position of the slag feeding trough is located at the lowest point of the inclination of the bottom of the feeding trough.

[0009] As a further solution of the present invention: from the perspective along the length direction of the feeding trough, the feeding trough is in an inverted V-shaped structure with a raised middle part, and the slag feeding trough is provided in two groups distributed on both sides of the bottom of the feeding trough.

[0010] As a further solution of the present invention: in the perspective perpendicular to the bottom of the feeding trough, the first end of the reinforcing steel bar is inclined toward the outlet end of the feeding trough, and the slag feeding trough is located at the first end of the reinforcing steel bar.

[0011] As a further solution of the present invention: from a perspective perpendicular to the bottom of the feed trough, the first end and the second end of the reinforcing steel bar are inclined toward the outlet end of the feed trough and form a V-shaped structure, and the slag feeding trough is arranged as two groups distributed on both sides of the bottom of the feed trough.

[0012] As a further solution of the present invention: the end of the reinforcing steel bar extends upward along the trough wall of the feeding trough to the notch of the feeding trough.

[0013] As a further solution of the present invention: the interval between adjacent reinforcing steel bars is 50 mm.

[0014] As a further solution of the present invention: backpack slots distributed along the length direction of the feeding trough are fixed to the outer periphery of the feeding trough.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The bottom of the feed trough is equipped with reinforcing steel bars connecting the trough walls on both sides of the feed trough. The reinforcing steel bars are arranged to be spaced along the length of the feed trough and cover the entire feed trough, so as not to increase the gravity of the feed trough too much. During use, the reinforcing steel bars are used to initially receive the coal blocks fed into the feed trough, reducing the damage caused by the coal blocks to the bottom of the feed trough when they are fed into the feed trough. At the same time, the reinforcing steel bars covering the entire bottom of the feed trough can also serve as the main bearing member for the downward sliding transportation of the coal blocks. The friction and wear between the reinforcing steel bars and the coal blocks are prioritized, thereby reducing the friction damage to the bottom plate of the feed trough and increasing the service life of the feed trough.

[0017] In addition, a slag trough is installed at the bottom of the feed trough along its length. Adjacent reinforcing steel bars and the bottom of the feed trough form a diversion channel that guides coal slag into the slag trough. This ensures the trough's drainage and transfer effectiveness without excessively increasing the weight of the feed trough and extending its service life.

[0018] 2. From the perspective of the length of the feed trough, the bottom of the feed trough is inclined, and the slot of the slag trough is located at the lowest point of the inclination of the bottom of the feed trough, so that the coal slag in the guide trough can be stably transported into the slag trough under its own weight, ensuring the effect of the slag trough in guiding and discharging coal slag.

[0019] 3. From a perspective perpendicular to the bottom of the feed trough, the first end of the reinforcing steel bar is inclined toward the outlet end of the feed trough, and the slag trough is located at the end of the reinforcing steel bar adjacent to the outlet end of the feed trough, so that the coal slag in the guide trough will be stably transported along the oblique side of the reinforcing steel bar toward the outlet end of the feed trough under the action of its own weight, that is, it will slide toward the first end of the reinforcing steel bar, and thus directly diverted into the slag trough under the action of gravity, ensuring the effect of the slag trough in guiding and discharging coal slag.

[0020] 4. The feed trough is equipped with backpack slots, distributed along its length, along its outer perimeter. Specifically, these slots can be made of lightweight materials, without excessively increasing the overall weight of the feed trough. Furthermore, even if the feed trough leaks, the backpack slots can be used to temporarily collect and transport the fallen coal slag, preventing contamination of the workshop environment and eliminating the need for workers to collect leaked coal chunks.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] For ease of understanding, the specific structure and working mode of the present invention are further described below with reference to the accompanying drawings:

[0027] The specific structure of the utility model refers to Figure 1-3 As shown, its main structure includes a feed trough 10 for transporting coal blocks. The bottom of the feed trough 10 is provided with reinforcing steel bars 30 connecting the two side walls of the feed trough 10. The reinforcing steel bars 30 are arranged in a plurality of intervals along the length of the feed trough 10 and cover the entire feed trough 10. This not only strengthens the bottom of the feed trough 10, but also serves to initially receive the coal blocks fed into the feed trough 10, reducing the impact damage to the bottom of the feed trough 10 when the coal blocks are fed into the feed trough 10. At the same time, the reinforcing steel bars 30 covering the entire bottom of the feed trough 10 also serve as the main support for the coal blocks to slide downward during transport. The friction and wear between the reinforcing steel bars 30 and the coal blocks are prioritized, reducing friction damage to the bottom plate of the feed trough 10 and extending the service life of the feed trough 10. The present invention uses the spaced reinforcing steel bars 30 instead of thickened steel plates, effectively reducing the overall weight of the feed trough 10 and improving the convenience of the installation operation of the feed trough 10.

[0028] Of course, due to the spaced distribution of the reinforcing steel bars 30, some coal slag will fall into the spaces between adjacent reinforcing steel bars 30; to ensure that the coal slag can also be stably guided downward, the present invention provides a slag trough 11 arranged along the length of the feeding trough 10 at the bottom of the feeding trough 10, and a guide trough is formed between the adjacent reinforcing steel bars 30 and the bottom of the feeding trough 10 to guide the coal slag toward the slag trough 11. The guide trough can guide the coal slag at the spaces between adjacent reinforcing steel bars 30 toward the slag trough 11, thereby ensuring the guiding and transporting effect of the feeding trough 10 while improving the service life of the feeding trough 10.

[0029] Based on the above, two implementation methods for forming the guide groove are provided below:

[0030] Example 1:

[0031] like Figure 2As shown, the bottom of the feed trough 10 is inclined from the perspective of the length of the feed trough 10, and the notch of the slag trough 11 is located at the lowest point of the inclination of the bottom of the feed trough 10. Since the bottom of the feed trough 10 is the bottom of the guide trough, the guide trough is gradually inclined from the perspective of the length of the feed trough 10, and the lowest point of the inclination is located at the notch of the slag trough 11, so that the coal slag in the guide trough can be transported into the slag trough 11 under the action of its own weight.

[0032] Further, such as Figure 2 As shown, the feed trough 10 has an inverted V-shaped or arched structure with a raised center, viewed along its length. The slag troughs 11 are arranged in two groups on either side of the bottom of the feed trough 10. This arrangement allows the coal slag to be discharged into the slag troughs 11 on both sides before being transferred downward for discharge, improving the efficiency of coal slag discharge.

[0033] Of course, in actual implementation, according to the actual coal slag discharge requirements, the feeding trough 10 can also adopt an inclined straight structure, an arch structure, a W-shaped structure or a wavy structure, and the number of slag feeding troughs 11 is set accordingly according to the number of the lowest points of the feeding trough 10 structure.

[0034] Example 2

[0035] like Figure 3 As shown, from a perspective perpendicular to the bottom of the feed trough 10, the first end of the reinforcing steel bar 30 is inclined toward the outlet end of the feed trough 10, and the slag trough 11 is located at the first end of the reinforcing steel bar 30. Since the feed trough 10 itself is in an inclined installation structure, the coal slag in the guide trough will flow along the inclined edge of the reinforcing steel bar 30 toward the outlet end of the feed trough 10, that is, slide toward the first end of the reinforcing steel bar 30, and then be directly guided into the slag trough 11 under the action of gravity.

[0036] Further, such as Figure 3 As shown, from a perspective perpendicular to the bottom of the feed trough 10, the first and second ends of the reinforcing steel bars 30 are inclined toward the outlet of the feed trough 10 to form a V-shaped structure. The slag troughs 11 are arranged in two groups on both sides of the bottom of the feed trough 10. This arrangement allows the coal slag to be discharged to the slag troughs 11 on both sides before being transferred downward for discharge, improving the efficiency of coal slag discharge.

[0037] On the basis of the above, if Figure 1 As shown, the end of the reinforcing steel bar 30 extends upward along the trough wall of the feed trough 10 to the notch of the feed trough 10, which not only increases the connection strength between the reinforcing steel bar 30 and the feed trough 10, but also improves the wear resistance of the side wall of the feed trough 10, further improving the service life of the feed trough 10.

[0038] In addition, if Figure 1 As shown, the spacing between adjacent reinforcing steel bars 30 is 50 mm, which can accommodate most coal blocks and effectively reduce the overall weight of the feeding trough 10. Of course, in actual implementation, the width of the spacing can be adjusted according to the actual size of the coal blocks.

[0039] It is worth mentioning that Figure 1 As shown, the feed trough 10 is secured with a backpack trough 20 extending along its length. Specifically, the backpack trough 20 can be made of lightweight materials, without excessively increasing the overall weight of the feed trough 10. The backpack trough 20 allows for the temporary collection and transfer of fallen coal slag even in the event of a leak. The backpack trough 20 not only prevents contamination of the workshop environment but also eliminates the need for workers to perform the additional task of collecting leaked coal.

[0040] Of course, it will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, but also encompasses the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and it is intended that all variations that fall within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.

[0041] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
