[0031] The embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar notations represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are for the purpose of explanation only, and are not to be construed as limiting the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0032] As shown in the drawings, Figure 1 The present disclosure provides a large-inclination angle transloading belt conveyor, which comprises a truss 1, a discharging head 2, a reversing tail 3, a plurality of roller groups 4 and a belt 5. The truss 1 is arranged obliquely, and the inclination angle of the truss 1 is greater than a preset angle. The discharging head 2 is arranged at the high end of the truss 1, and the reversing tail 3 is arranged at the low end of the truss 1. The plurality of roller groups 4 are arranged along the length direction of the truss 1 and are spaced between the discharging head 2 and the reversing tail 3, and the spacing between adjacent roller groups 4 is less than a preset spacing. The belt 5 is arranged on the discharging head 2, the reversing tail 3 and the plurality of roller groups 4, and the discharging head 2 is used to drive the upper half of the belt 5 to convey the slag in the direction from the reversing tail 3 to the discharging head 2.

[0033] It can be understood that, since the discharging head 2 is arranged at the high end of the truss 1, and the reversing tail 3 is arranged at the low end of the truss 1, and the plurality of roller groups 4 are arranged along the length direction of the truss 1 and are spaced between the discharging head 2 and the reversing tail 3, the belt 5 can be arranged on the truss 1 by using the discharging head 2, the reversing tail 3 and the plurality of roller groups 4, and can also convey the slag in the direction from the reversing tail 3 to the discharging head 2 under the driving of the discharging head 2. Moreover, since the truss 1 is arranged obliquely, and the inclination angle of the truss 1 is greater than a preset angle, the belt 5 can be arranged at a large inclination angle by using the truss 1, thereby adapting to the excessive height difference between the material receiving point and the discharging point. At the same time, since the spacing between adjacent roller groups 4 is less than a preset spacing, the plurality of roller groups 4 are arranged densely, thereby increasing the conveying capacity of the belt 5 by using the more dense roller groups 4, and reducing the risk of slag sliding. Thus, while realizing the large-inclination angle arrangement, the transloading belt conveyor also ensures high slag conveying quality and efficiency.

[0034] It should be noted that the truss 1 is arranged between a lower receiving point and a higher discharging point, and serves to bear the discharging head 2, the reversing tail 3, the roller group 4 and the like, the low end of the truss 1 is close to the receiving point, the high end of the truss 1 is close to the discharging point, and the specific type of the truss 1 can be set according to actual needs, which is not limited, for example, the truss 1 is connected by a plurality of beams, a plurality of vertical beams and the like, and the truss 1 is arranged on a plurality of supports.

[0035] The discharging head 2 is used to drive the belt 5 to run and discharge the belt 5, and the specific type of the discharging head 2 can be set according to actual needs, which is not limited.

[0036] The reversing tail 3 is used for reversing the belt 5, and the specific type of the reversing tail 3 can be set according to actual needs, which is not limited.

[0037] The roller group 4 is used for supporting and guiding the belt 5, and the specific type of the roller group 4 can be set according to actual needs, which is not limited, for example, the roller group 4 includes an upper roller group for supporting and guiding the upper half (conveying part) of the belt 5, a lower roller group for supporting and guiding the lower half (return part) of the belt 5, and beams, vertical beams and the like supporting the upper roller group and the lower roller group, wherein the two sides of the roller group 4 can be set as adjustable structure, and the deviation of the angle is offset, so as to realize the deviation control of the belt 5.

[0038] The belt 5 is used for conveying slag, and the specific type of the belt 5 can be set according to actual needs, which is not limited.

[0039] Among them, for the preset angle and the preset interval, they can be set according to actual needs, which is not limited, for example, the preset angle can be 10 degrees, that is, the inclination angle of the truss 1 is greater than 10 degrees, and the whole is arranged as a large inclination angle, and the preset interval can be 1 m, that is, the interval between adjacent roller groups 4 is less than 1 m, and the whole is arranged as an encryption.

[0040] In some embodiments, the inclination angle of the truss 1 ranges from 10° to 13°, the interval between adjacent roller groups 4 ranges from 0.5 m to 1 m, and the friction coefficient between the belt 5 and the slag ranges from 0.5 to 0.7.

[0041] It can be understood that, since the inclination angle of the truss 1 ranges from 10° to 13°, the belt 5 can be arranged at a large inclination angle by using the truss 1, thereby adapting to a large height difference between the receiving point and the discharging point; and since the spacing between adjacent groups of rollers 4 ranges from 0.5 m to 1 m, the plurality of groups of rollers 4 are arranged in a dense manner, thereby increasing the conveying capacity of the belt 5 by using more dense groups of rollers 4; and since the friction coefficient between the belt 5 and the slag ranges from 0.5 to 0.7, the belt 5 is arranged to have a high friction coefficient, thereby increasing the conveying capacity of the belt 5 by using a larger friction force. Thus, while achieving a large inclination angle arrangement, the risk of slag sliding is effectively reduced, thereby ensuring a high slag discharge quality and efficiency of the transfer belt conveyor.

[0042] It should be noted that the inclination angle of the truss 1 can be set according to actual needs, and is not limited, for example, the inclination angle of the truss 1 can be 10°, 11°, 12°, 12.3°, 13°, etc.

[0043] The spacing between adjacent groups of rollers 4 can be set according to actual needs, and is not limited, for example, the spacing between adjacent groups of rollers 4 can be 0.5 m, 0.6 m, 0.7 m, 0.8 m, 1 m, etc.

[0044] The friction coefficient between the belt 5 and the slag can be set according to actual needs, and is not limited, for example, the friction coefficient between the belt 5 and the slag can be 0.5, 0.6, 0.66, 0.7, etc.

[0045] As shown in Figure 2 and Figure 3 In some embodiments, the discharging head 2 includes a sealed discharge hopper 21, a transmission drum 22, and a driving device 23, the sealed discharge hopper 21 is arranged at the high end of the truss 1, the transmission drum 22 is rotationally arranged in the sealed discharge hopper 21, and the belt 5 passes through the transmission drum 22, the driving device 23 is arranged on the truss 1, and the driving device 23 and the transmission drum 22 are drivingly connected, and the driving device 23 is used to drive the transmission drum 22 to rotate, so as to drive the upper half of the belt 5 to convey the slag in the direction from the reversing tail 3 to the discharging head 2.

[0046] It can be understood that, since the transmission drum 22 is rotationally arranged in the sealed discharge hopper 21, and the driving device 23 and the transmission drum 22 are drivingly connected, after the belt 5 passes through the transmission drum 22, the belt 5 can be conveyed and sealedly discharged by using the sealing structure of the sealed discharge hopper 21 and the driving of the driving device 23, thereby reducing leakage and improving conveying quality and efficiency.

[0047] It should be noted that the sealed discharge hopper 21 is used to form a relatively closed discharge space at the discharge end of the belt 5 (at the driving roller 22), and the specific type of the sealed discharge hopper 21 can be set according to actual needs, and no limitation is made to this. For example, the sealed discharge hopper 21 can be a closed bucket structure, and the top or side of the bucket structure is provided with a feeding port accommodating the discharge end of the belt 5, and the periphery of the feeding port is provided with a flexible sealing element, and the bottom of the bucket structure is provided with a discharge port for discharging.

[0048] The driving roller 22 is used to rotate under the driving of the driving device 23 to drive the belt 5 to run, and the specific type of the driving roller 22 can be set according to actual needs, and no limitation is made to this. For example, the driving roller 22 is a roller structure, and is rotatably arranged in the sealed discharge hopper 21. The rotating shaft of the driving roller 22 extends out of the sealed discharge hopper 21 and is connected in transmission with the driving device 23.

[0049] The driving device 23 is used to drive the driving roller 22 to rotate to drive the belt 5 to run by the rotation of the driving roller 22, and the specific type of the driving device 23 can be set according to actual needs, and no limitation is made to this. For example, the driving device 23 can be a motor and a speed reducer, and the motor is connected in transmission with the driving roller 22 through the speed reducer.

[0050] As shown in Figure 2 In some embodiments, the discharge head 2 further comprises a plurality of scrapers 24 arranged in the sealed discharge hopper 21, and the scraping end of the scraper 24 is close to the belt 5. The plurality of scrapers 24 are distributed along the running direction of the belt 5.

[0051] It can be understood that since the scraper 24 is arranged in the sealed discharge hopper 21, and the scraping end of the scraper 24 is close to the belt 5, and the plurality of scrapers 24 are distributed along the running direction of the belt 5, the plurality of scrapers 24 can effectively remove the slag, sundries and the like attached to the belt 5, thereby ensuring the efficient running of the belt 5.

[0052] It should be noted that the scraper 24 is used to scrape the slag, sundries and the like on the belt 5, and the specific type of the scraper 24 can be set according to actual needs, and no limitation is made to this. For example, the scraper 24 can be an alloy scraper 24.

[0053] As shown in Figure 2 In some embodiments, a spraying device 25 is arranged between adjacent scrapers 24, and the spraying end of the spraying device 25 faces the belt 5.

[0054] It can be understood that, since the spraying devices 25 are arranged between the adjacent scrapers 24 and the spraying ends of the spraying devices 25 face the belt 5, the slag, sundries and the like adhering to the belt 5 can be effectively removed by the plurality of spraying devices 25, thereby ensuring the efficient operation of the belt 5.

[0055] It should be noted that the spraying devices 25 cooperate with the scrapers 24 to remove the slag, sundries and the like adhering to the belt 5, and the specific type of the spraying devices 25 can be set according to actual needs, which is not limited, for example, the spraying devices 25 pressurize the field cleaning water source and spray it on the belt 5 by cooperating with the pump body and the spray head, and the automatic operation of spraying is realized by the on-off of the valve body and the like.

[0056] As shown in Figure 4 In some embodiments, the belt conveyor further comprises a material receiving device 6, which comprises a sealed material receiving hopper 61 and a buffer idler 62. The sealed material receiving hopper 61 and the buffer idler 62 are respectively arranged at one end of the truss 1 close to the reversing machine tail 3, and the buffer idler 62 is located below the discharge end of the sealed material receiving hopper 61, and the belt 5 passes through the buffer idler 62.

[0057] It can be understood that, since the buffer idler 62 is located below the discharge end of the sealed material receiving hopper 61, and the belt 5 passes through the buffer idler 62, the slag can enter the belt 5 supported and guided by the buffer idler 62 through the sealed material receiving hopper 61, and then the slag is transported by the operation of the belt 5.

[0058] The sealing structure of the sealed material receiving hopper 61 can reduce the leakage problem during the material receiving process of the belt 5, and the buffer structure of the buffer idler 62 can buffer the impact of the large particle size slag during the material receiving process of the belt 5, thereby reducing the impact, wear and the like of the belt 5.

[0059] It should be noted that the sealed material receiving hopper 61 is used to form a relatively closed material receiving space at the material receiving position of the belt 5, and the specific type of the sealed material receiving hopper 61 can be set according to actual needs, which is not limited, for example, the sealed material receiving hopper 61 can be a closed hopper structure, and the top or side of the hopper structure is provided with a receiving discharge chute, the periphery of the feeding port is provided with a flexible sealing element, and the bottom of the hopper structure is provided with a discharge port for discharging, and the discharge port is arranged close to the belt 5.

[0060] The buffer idler 62 is used to support and guide the belt 5 and buffer the impact of the large particle size slag, and the feeding end of the belt 5 is located at the buffer idler 62, and the specific type of the buffer idler 62 can be set according to actual needs, which is not limited.

[0061] As shown in Figure 4As shown, in some embodiments, the receiving device 6 further includes: a plurality of anti-overflow skirts 63, which are disposed on both sides of the discharge end of the sealed receiving hopper 61 and are disposed close to the belt 5.

[0062] It is understandable that, since the anti-overflow skirt 63 is set on both sides of the discharge end of the sealed receiving hopper 61 and is set close to the belt 5, the anti-overflow skirt 63 can form a limit on both sides of the belt 5, thereby reducing the leakage of slag during the material receiving process of the belt 5, and thus ensuring the high conveying quality and efficiency of the belt 5.

[0063] It should be noted that the anti-overflow skirt 63 is used to form a limit on both sides of the belt 5 to reduce the overflow of slag. The specific type of anti-overflow skirt 63 can be set according to actual needs and there is no restriction. For example, the anti-overflow skirt 63 is an inclined plate structure, and the anti-overflow skirt 63 is set close to the belt 5 and does not affect the operation of the belt 5.

[0064] like Figure 5 As shown, in some embodiments, the reversing gear tail 3 includes: a tensioning seat 31, a reversing roller 32, and an adjusting threaded rod 33. The tensioning seat 31 is slidably disposed at the lower end of the truss 1 along the length direction of the truss 1. The reversing roller 32 is rotatably disposed on the tensioning seat 31, and the belt 5 passes around the reversing roller 32. The adjusting threaded rod 33 is rotatably disposed on the truss 1, and the adjusting threaded rod 33 and the tensioning seat 31 are threadedly connected.

[0065] It is understandable that, since the reversing roller 32 is rotatably mounted on the tensioning seat 31 and the belt 5 passes around the reversing roller 32, the belt 5 can be reversed using the reversing roller 32, thereby achieving stable material conveying and return. Furthermore, since the tensioning seat 31 is slidably mounted at the lower end of the truss 1 along the length direction of the truss 1, and the adjusting threaded rod 33 is threadedly connected to the tensioning seat 31, the adjusting threaded rod 33 can drive the tensioning seat 31 to move at the lower end of the truss 1 along the length direction of the truss 1. Thus, the tension of the belt 5 can be adjusted by the movement of the tensioning seat 31, thereby meeting the different tension requirements of the belt 5.

[0066] It should be noted that the tensioning seat 31 is used to support the reversing roller 32 and to move along the length of the truss 1 under the drive of the adjusting threaded rod 33. The specific type of the tensioning seat 31 can be set according to actual needs and there is no limitation. For example, the tensioning seat 31 can be a seat structure that is close to a U-shape, which uses the cooperation of guide rails, rail grooves, etc. to achieve sliding setting at the lower end of the truss 1.

[0067] The reversing roller 32 is used for reversing the belt 5 at the low end of the truss 1. The specific type of the reversing roller 32 can be set according to actual needs, and no limitation is made thereto. For example, the reversing roller 32 is a roller structure, which is rotatably arranged on the tensioning seat 31 by a bearing, and the central axis of the reversing roller 32 is located in the width direction of the truss 1.

[0068] The adjusting threaded rod 33 is used for driving the linear movement of the tensioning seat 31 by thread cooperation with the tensioning seat 31. The specific type of the adjusting threaded rod 33 can be set according to actual needs, and no limitation is made thereto. The rotation of the adjusting threaded rod 33 can be manually driven or electrically driven.

[0069] As shown in Figure 1 some embodiments, the belt conveyor further comprises a material guide chute 7, which is arranged on the truss 1, and the slot of the material guide chute 7 is located below the lower half of the belt 5.

[0070] It can be understood that, since the material guide chute 7 is arranged on the truss 1, and the slot of the material guide chute 7 is located below the lower half of the belt 5, the material guide chute 7 can collect the residual muck and spraying water of the lower half of the belt 5, thereby reducing the problem of spilling and ensuring civilized and sanitary construction.

[0071] It should be noted that the material guide chute 7 is used for collecting the residual muck and spraying water of the lower half of the belt 5. The specific type of the material guide chute 7 can be set according to actual needs, and no limitation is made thereto. For example, the material guide chute 7 is a long slot structure, which is arranged at the bottom of the truss 1 along the length direction of the truss 1. The material guide chute 7 needs to be cleaned after use.

[0072] As shown in Figure 6 some embodiments, the belt conveyor further comprises a maintenance platform 8, which is arranged on the truss 1, and the maintenance platform 8 is arranged along the circumference of the truss 1.

[0073] It can be understood that, since the maintenance platform 8 is arranged on the truss 1, and the maintenance platform 8 is arranged along the circumference of the truss 1, the working personnel can move around the truss 1 by using the maintenance platform 8, thereby facilitating the maintenance and other operations of the belt conveyor.

[0074] It should be noted that the specific type of the maintenance platform 8 can be set according to actual needs, and no limitation is made thereto.
