Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to an iron ore crushing material conveyor. Background Art

[0002] Iron ore crushed material refers to the iron ore particles that have been crushed. It is generally used in steel metallurgical production, construction industry, road construction industry, chemical industry and phosphate industry. Therefore, it is necessary to centrally transport and transfer the crushed iron ore crushed materials in the early stage.

[0003] In the prior art, conveyor belts are primarily used to transport and transfer iron ore. A search revealed patent application number CN202321745252.8, which discloses an iron ore mining and conveying device. The device primarily includes a belt, a bearing rod, a driven roller, a driving roller, a first support, an idler roller, a second support, a crowning roller, and a tooth assembly.

[0004] When working, the above-mentioned conveying device relies on the meshing structure added between the roller and the belt, so that when the belt is transmitted on the roller, it can synchronously drive the roller to reduce the friction between the roller and the belt. However, it is necessary to open tooth holes at equal intervals on the belt. This structure has the following disadvantages: First, since the transmission needs to be coordinated between the teeth and the tooth holes on the belt, the long-term force on the belt may easily cause damage to the tooth holes, thereby reducing the service life of the belt; second, after the tooth holes are opened on the belt surface, holes will appear on the belt surface, which may easily cause material scattering when conveying iron ore crushed materials with smaller particle sizes, affecting the conveying effect.

[0029] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the present invention's technical solution and are therefore only examples and are not intended to limit the scope of protection of the present invention. Figures 1-4 As shown in .

[0030] Example 1: An iron ore crushing material conveyor, comprising a mounting base 1, wherein ground-connected columns 2 are fixedly installed at the four corners of the bottom of the mounting base 1, and the bottom of each ground-connected column 2 is fixed on the ground 3. Lateral support frames 4 are fixedly arranged at intervals and symmetrically on the front and rear sides above the mounting base 1, and an upper roller unit and a lower roller unit are installed in sequence from top to bottom in the space between the two lateral support frames 4. Closed-loop conveyor belts 5 are respectively wound around the periphery of the upper roller unit and the lower roller unit, and the conveyor belts 5 are wound around the outer side walls of the upper roller unit and the lower roller unit. The power input end 701 of the lower roller unit is used to connect to an external drive device, and lateral tensioning mechanisms are symmetrically installed on the left and right sides of each lateral support frame 4, and the outer ends of the lateral tensioning mechanisms abut against the inner side walls of the conveyor belt 5.

[0031] It should be noted that: when the iron ore crushing material is being conveyed by the iron ore crushing material conveyor in the present invention, it is mainly carried below the dropping end of the iron ore crushing material. When the iron ore crushing material falls to the top of the conveyor belt 5, the conveyor belt 5 is in operation under the action of the external driving force. During the operation of the conveyor belt 5, the iron ore crushing material can be continuously conveyed downstream in the horizontal direction. When it is conveyed to the end, the inclined guide section 501 formed at the end of the conveyor belt 5 can realize the transfer and transportation of the iron ore crushing material on the conveyor belt 5 to the downstream, thereby effectively ensuring the stability of material transportation.

[0032] In addition, due to the provision of the upper roller unit and the lower roller unit distributed up and down, the contact area with the conveyor belt 5 is effectively increased, thereby ensuring the stability of the conveyor belt 5 during conveying operation and improving its load-bearing capacity during operation.

[0033] In any of the above solutions, preferably, the top and bottom of the conveyor belt 5 are both arranged horizontally.

[0034] The top and bottom of the conveyor belt 5 are both horizontal, which can ensure stability when conveying the crushed iron ore.

[0035] In any of the above schemes, it is preferred that the upper roller unit includes a plurality of upper belt rollers 6 arranged at intervals in the horizontal direction, the upper outer side wall of each upper belt roller 6 cooperates with the toothed inner side wall of the conveyor belt 5, and the front and rear ends of each upper belt roller 6 are movably inserted into the mounting hole at the corresponding position of the lateral support frame 4 through the central axis 7.

[0036] In any of the above schemes, it is preferred that the lower roller unit includes a plurality of lower belt rollers 8 spaced apart in the horizontal direction, the lower outer side walls of each of the lower belt rollers 8 cooperate with the toothed inner side walls of the conveyor belt 5, and the front and rear ends of each of the lower belt rollers 8 are movably inserted into the mounting holes at the corresponding positions of the lateral support frame 4 through the central shaft 7; the lower belt roller 8 located on the far right serves as a driving member and its central shaft 7 serves as a power input end 701 connected to the external driving device.

[0037] The upper roller unit and the lower roller unit respectively rely on a plurality of upper belt rollers 6 and lower belt rollers 8 arranged at intervals to effectively tension the entire conveyor belt 5, ensuring that the upper belt rollers 6 and lower belt rollers 8 of the entire conveyor belt 5 play an overall supporting role when the upper belt rollers 6 and lower belt rollers 8 are in operation, thereby effectively ensuring the tension strength of the entire conveyor belt 5.

[0038] In any of the above solutions, it is preferred that each of the lower belt rollers 8 is located directly below the upper belt roller 6 at its corresponding position.

[0039] The upper belt roller 6 and the lower belt roller 8 are arranged opposite to each other, which can effectively ensure the relative symmetry of the force applied to the conveyor belt during installation and reduce the probability of the conveyor belt 5 being twisted and deformed.

[0040] In any of the above solutions, it is preferred that the conveyor belt 5 is a toothed conveyor belt.

[0041] Toothed conveyor belts can better increase the bite force during transmission and reduce the probability of belt slippage.

[0042] Example 2: Compared with Example 1, this example is different in that it also includes the following technical features:

[0043] In any of the above schemes, it is preferred that the lateral tensioning mechanism includes an adjusting cylinder 9 respectively installed on the corresponding ends of the two lateral support frames 4, the inner end of the cylinder barrel of the adjusting cylinder 9 is movably hinged to a bracket ear seat 11 through a tail end ear seat 10 fixed at its end, and the bracket ear seat 11 is fixed to the end of the lateral support frame 4, and a horizontally arranged linkage shaft 12 is fixedly welded on one side of the adjusting cylinder 9, the outer end of the linkage shaft 12 is movably hinged to the top of a slope adjustment unit, and the lower end of the slope adjustment unit is movably hinged to the top ear seat 13 fixed to the top of the mounting base 1; a tensioning member is provided between the two adjusting cylinders 9 arranged opposite to each other in the front and rear, and the outer side wall of the tensioning member abuts against the inner side wall of the conveyor belt 5.

[0044] When the lateral tensioning mechanism is working, it mainly relies on the expansion and contraction of the inclination adjustment unit to drive the swing of the adjustment cylinder 9. At the same time, during the swing of the adjustment cylinder 9, its expansion and contraction will also follow the needs, thereby achieving the effective tightening effect of the tensioning member on the inner wall of the current conveyor belt 5.

[0045] In any of the above schemes, it is preferred that the inclination adjustment unit includes an obliquely arranged telescopic electric cylinder 14, the bottom of the cylinder barrel of the telescopic electric cylinder 14 is movably hinged on the top ear seat 13, and the top of the piston rod of the telescopic electric cylinder 14 is movably sleeved on the outer wall of the linkage shaft 12 through a fixed earring 15.

[0046] The inclination adjustment unit mainly relies on the extension and contraction of the telescopic electric cylinder 14 to drive the swing of the linkage shaft 12 and the cylinder barrel of the adjusting cylinder 9 thereon, and cooperates with the extension and contraction of the piston rod of the current adjusting cylinder 9 to achieve the purpose of controlling the current tensioning member to abut against the inner wall of the conveyor belt 5 at different positions, thereby being able to tension the conveyor belt 5. At the same time, when the position of the inner wall of the conveyor belt 5 is different, the inclination angle of the end of the conveyor belt 5 will also change.

[0047] In any of the above schemes, it is preferred that the tensioning member includes a horizontally arranged tensioning roller 16, and both ends of the central axis 7 of the tensioning roller 16 are movably inserted into the restraining earrings 17 fixed to the end of the piston rod of the adjusting cylinder 9.

[0048] The tensioning roller 16 in the tensioning member can realize fixed-axis rotation, thereby effectively ensuring the tightening effect of the entire tensioning roller 16 when abutting against the inner side wall of the conveyor belt 5, while ensuring smoothness during fixed-axis rotation.

[0049] In any of the above solutions, it is preferred that the two adjusting cylinders 9 located at the same end are in a synchronous telescopic state during operation; and the two telescopic electric cylinders 14 located at the same end are in a synchronous telescopic state during operation.

[0050] Maintaining the synchronous extension and retraction of the two adjusting cylinders 9 can ensure synchronization when tightening the end of the current conveyor belt 5; maintaining the synchronous extension and retraction of the two telescopic electric cylinders 14 can ensure synchronization when adjusting the tilt and swing angle of the current adjusting cylinder 9.

[0051] Example 3: Compared with Example 2, this example is different in that it also includes the following technical features:

[0052] Both left and right ends of the conveyor belt 5 form an external inclined material guide section 501 that is arranged to be inclined downward. The inclined material guide section 501 is used to cooperate with external conveying equipment.

[0053] The inclined guide sections 501 provided at both ends can better ensure the stability of the iron ore crushed materials when they are transferred at the upstream and downstream ends, ensuring that they can maintain a smooth transition connection with the upstream conveying equipment and the downstream conveying equipment.

[0054] Specific working principle: When conveying iron ore crushed materials, it is mainly carried below the falling end of the iron ore crushed materials. When the iron ore crushed materials fall to the top of the conveyor belt 5, the conveyor belt 5 is in operation under the action of external driving force. During the operation of the conveyor belt 5, the iron ore crushed materials can be continuously conveyed downstream in the horizontal direction.

[0055] When conveying to the end, the inclined guide section 501 formed at the end of the conveyor belt 5 can realize the transfer and transportation of the iron ore crushed material on the conveyor belt 5 to the downstream, effectively ensuring the smooth transportation of materials. In addition, the upper roller unit and the lower roller unit respectively rely on multiple upper belt rollers 6 and lower belt rollers 8 arranged at intervals to effectively tension the entire conveyor belt 5. This ensures that the upper belt rollers 6 and lower belt rollers 8 of the entire conveyor belt 5 play an integral supporting role during operation, effectively ensuring the tension strength of the entire conveyor belt 5.

[0056] When tensioning is required, the lateral tensioning mechanism mainly relies on the expansion and contraction of the inclination adjustment unit to drive the swing of the adjustment cylinder 9. At the same time, during the swing of the adjustment cylinder 9, its expansion and contraction will also follow the needs, thereby achieving an effective tightening effect of the tensioning member on the inner wall of the current conveyor belt 5.

[0057] From the above, it can be seen that the iron ore crushing material conveyor can ensure its smooth operation after being powered by an external power device. When the conveyor belt 5 in the equipment is running, it can receive the iron ore crushing material and transport it horizontally to the downstream to ensure the smoothness of transportation; the conveyor adopts the upper roller unit and the lower roller unit to cooperate with each other so that the conveyor belt 5 can be fully tensioned during the entire conveying process, effectively improving the overall load-bearing performance of the entire conveyor when conveying iron ore crushing material; in the process of conveying iron ore crushing material, the adjustment of the lateral tensioning mechanism on both sides can effectively tighten the tension of the entire conveyor belt 5 as needed to avoid the belt slippage caused by excessive relaxation of the belt; this lateral tensioning mechanism can not only effectively adjust the tightness of the current conveyor belt 5 when adjusting, but also effectively adjust the inclination angle of the inclined guide section 501 at both ends, so as to achieve the purpose of facilitating the adjustment of the current conveyor belt 5 when it is connected with the upstream and downstream conveying equipment.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents.
