DETAILED DESCRIPTION

[0018] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0019] In the present disclosure, unless otherwise specified, directional words such as "inside" and "outside" refer to the inside and outside relative to the outline of the structure or component itself; "first, second" and the like are intended to distinguish one element from another and have no order or importance. In addition, the same figure marks in different reference drawings represent the same elements.

[0020] The present invention provides a material guiding device, referring to Figures 1 to 5 As shown, the material guiding device includes a conveyor belt 1, a material guiding pipe 2 and a driving mechanism 3, wherein the material guiding pipe 2 includes a first section 210 and a second section 220, the first section 210 and the second section 220 together form a material guiding channel 201, the first section 210 is provided with a material inlet 211, the second section 220 is provided with a material outlet 221 facing the conveyor belt 1, and the material guiding pipe 2 is constructed so that the second section 220 can rotate relative to the first section 210; the driving mechanism 3 includes a first driving component 310 connected to the second section 220, and the first driving component 310 is used to drive the second section 220 to rotate relative to the first section 210.

[0021] Through the above scheme, that is, the material guiding device provided by the present invention, when the coal is transported through the material guiding device, the coal can enter the inside of the material guiding channel 201 from the feed port 211 at the first section 210 of the material guiding pipe 2, and pass through the first section 210 and the second section 220 in sequence and be discharged from the discharge port 221. The discharged coal will be carried by the conveyor belt 1. When the carried coal is accumulated in a part of the conveyor belt 1, the second section 220 can be driven to rotate relative to the first section 210 by the first driving component 310 of the driving mechanism 3, that is, the direction of the discharge port 221 can be fine-tuned, and then the position of the discharge port 221 toward the conveyor belt 1 can be changed (for example, it can be toward the position where the conveyor belt 1 is less accumulated when transporting coal), so as to reduce the deviation of the conveyor belt 1 due to uneven stacking of materials.

[0022] It should be noted that, in order to facilitate those skilled in the art to understand the above technical solution, the conveyor belt 1 can be a conveyor belt of a belt conveyor, and the belt conveyor can drive the conveyor belt 1 to transmit, for example, refer to Figure 1 As shown, the conveyor belt 1 can be along Figure 1 The coal is transported from left to right in the drawing direction. When the coal enters the guide channel 201 from the feed port 211, it will pass through the first section 210 and the second section 220 in sequence and be discharged from the discharge port 221. The material discharged from the discharge port 221 will fall onto the belt surface of the conveyor belt 1 to be transported. When the coal transport volume is large and the local belt surface of the conveyor belt 1 is over-accumulated, you can refer to Figure 2As shown, the first section 210 and the second section 220 can be hinged by the second hinge shaft 202, and a movable bellows 203 can be provided at the connection between the first section 210 and the second section 220, which can not only allow the second section 220 to rotate relative to the first section 210, but also seal the gap generated when the second section 220 rotates relative to the first section 210 to prevent the dust contained in the coal from escaping. In this connection mode, the second section 220 can be driven by the first driving component 310 of the driving mechanism 3 to perform clockwise or counterclockwise angle fine-tuning relative to the second hinge shaft 202. For example, it can rotate around the second hinge shaft 202 by a preset angle of 10° to 45° (exemplarily, not limited to this range), and then the position of the discharge port 221 toward the conveyor belt 1 can be adjusted. For example, the coal can be discharged toward a position on the belt surface of the conveyor belt 1 where there is less coal, so as to reduce the uneven stacking of the conveyor belt 1 and cause the conveyor belt 1 to deviate. In addition, in another embodiment not shown in the figure, the first section 210 and the second section 220 can also be plug-in-fitted, and the outer diameter of the first section 210 and the inner diameter of the second section 220 can also have a certain difference. For example, when the first section 210 is plugged into the second section 220, the first section 210 can have a movable margin with the second section 220, thereby facilitating the second section 220 to rotate relative to the first section 210.

[0023] In addition, it can be understood that the deviation of the conveyor belt 1 mentioned in the above embodiment is usually caused by uneven force on the belt surface of the conveyor belt 1. For example, when the local belt surface of the conveyor belt 1 carries too much coal, the pressure of the coal on the belt surface at that location is relatively large, which may cause the dangerous situation of the conveyor belt 1 being compressed and torn, and the coal will be unevenly stacked on the local belt surface. The belt surface can easily be rolled into the pulley of the conveyor belt 1 (not shown in the figure) and cause the belt to get stuck. The conveyor belt 1 cannot guarantee normal operation. The material guiding device provided in the present disclosure can minimize the uneven force on various parts of the conveyor belt 1 to reduce the deviation of the conveyor belt 1.

[0024] The first drive component 310 mentioned in the above embodiment can adopt any mechanism that can drive the second section 220 to rotate relative to the first section 210. For example, the first drive component 310 can adopt a suitable method such as hydraulic drive, pneumatic drive or motor drive. The present disclosure will describe the first drive component 310 in detail below, so no further details will be given here.

[0025] In some embodiments, reference Figures 1 to 5As shown, the material guide device also includes a mounting frame 4, and the first driving assembly 310 includes a first telescopic member 311, which is connected to the mounting frame 4 and the second section 220. The first telescopic member 311 is configured to be able to drive the second section 220 to rotate relative to the first section 210 through its own telescopic movement. In this way, the mounting frame 4 can be used for the installation of the first telescopic member 311, and the first telescopic member 311 can drive the second section 220 to rotate relative to the first section 210 through its own telescopic movement to adjust the position of the discharge port 221 toward the conveyor belt 1, and the first telescopic member 311 can adopt any suitable structure that can be telescopic, for example, refer to Figure 1 and Figure 2 As shown, the first telescopic member 311 can be a hydraulic telescopic rod, and the two ends of the hydraulic telescopic rod can be hinged to the mounting frame 4 and the second section 220 respectively, and can cooperate with the hydraulic pump 312 to drive the hydraulic telescopic rod to extend and retract, that is, when the hydraulic pump 312 drives the hydraulic telescopic rod to extend, the second section 220 will rotate counterclockwise around the second hinge axis 202, and when the hydraulic pump 312 drives the hydraulic telescopic rod to shorten, the second section 220 will rotate clockwise around the second hinge axis 202, thereby allowing the second section 220 to rotate relative to the first section 210 to change the direction of the discharge port 221. In addition, the first telescopic member 311 is not limited to the hydraulic telescopic rod mentioned in the above-mentioned embodiment. In other embodiments not shown in the figure, the first telescopic member 311 can also use a cylinder in combination with a pneumatic telescopic rod, or a linear motor to drive the second section 220 to rotate relative to the first section 210. The present disclosure does not make specific limitations on this.

[0026] In some embodiments, reference Figures 1 to 5 As shown, the material guiding device also includes a first material guiding mechanism 5, the number of the first material guiding mechanisms 5 is multiple and they are arranged at intervals along the extension direction of the material guiding channel 201, the first material guiding mechanism 5 includes a first material guiding plate 510 located in the first section 210, the top end of the first material guiding plate 510 is connected to the first section 210, the first material guiding plate 510 extends obliquely from the feed port 211 toward the discharge port 221 and toward the center line of the material guiding channel 201, and the two top ends of the two adjacent first material guiding plates 510 of any two adjacent first material guiding mechanisms 5 are respectively located on opposite sides of the center line of the material guiding channel 201. In this way, when the coal falls and is transported from the feed port 211 toward the discharge port 221 in the material guiding channel 201, it will pass through the multiple first material guiding plates 510 in sequence, and the multiple obliquely extending first material guiding plates 510 will buffer the falling coal, thereby preventing a large amount of coal from being discharged from the discharge port 221 when there is too much coal, thereby causing excessive local stacking of the conveyor belt 1 and uneven stacking, and, with reference to Figure 1 and Figure 3As shown, the multiple first material guide plates 510 of the multiple first material guide mechanisms 5 are arranged at intervals along the extension direction of the material guide channel 201, and are arranged alternately at intervals on the left and the right. When the coal passes through the material guide channel 201, the multiple first material guide plates 510 will alternately buffer the falling coal to further improve the buffering effect of the coal falling, thereby avoiding the situation where a large amount of coal is discharged from the discharge port 221 in a short time and excessive material is piled up locally on the conveyor belt 1. Among them, the center line of the material guide channel 201 can be understood as the line connecting the centers of each cross section of the material guide channel 201 perpendicular to the extension direction. The cross section of the material guide channel 201 can be selected according to actual needs, such as rectangular, square or even circular, etc., and the present disclosure is not limited thereto.

[0027] In some embodiments, reference Figures 1 to 5 As shown, the top end of the first guide plate 510 is hinged to the first section 210 through the first hinge shaft 501, and the first guide mechanism 5 also includes a second drive assembly 520, which is connected to the first guide plate 510, and the second drive assembly 520 is used to drive the first guide plate 510 to rotate around the first hinge shaft 501. In this way, that is, the first guide plate 510 is hinged to the first section 210 and the first guide plate 510 is driven to rotate by the second drive assembly 520, the flow rate of the coal when passing through the guide channel 201 can be flexibly controlled, that is, it can be understood that when multiple first guide plates 510 are in Figure 1 When the coal is kept in a vertical downward state, the flow rate of the coal in the guide channel 201 is the largest. When the first guide plate 510 is rotated by the first hinge shaft 501 and tilted relative to the first section 210, the flow rate of the coal is relatively reduced, that is, when the coal falls toward the discharge port 221 along the extension direction of the guide channel 201, it will contact multiple inclined and extended first guide plates 510 in turn, thereby reducing the falling speed, so as to reduce the local accumulation of coal on the conveyor belt 1 and cause the conveyor belt 1 to deviate. In addition, the inclination angle of the first guide plate 510 relative to the first section 210 can also be freely controlled by the second drive component 520, and the inclination angle can also be selected according to any suitable angle based on the displacement of the coal, for example, it can be 45°.

[0028] Furthermore, the second drive component 520 may also adopt any suitable drive structure, such as any of the hydraulic drive, pneumatic drive or motor drive mentioned in the above embodiments. The present disclosure will elaborate on the second drive component 520 in detail below and will not be elaborated herein.

[0029] In some embodiments, reference Figures 1 to 5As shown, the guide tube 2 also includes a mounting seat 230 connected to the first section 210, and a receiving cavity 231 is formed in the mounting seat 230. The second driving assembly 520 includes a second telescopic member 521 and an elastic member 522. The second telescopic member 521 is received in the receiving cavity 231; the elastic member 522 is connected between the output end of the second telescopic member 521 and the first guide plate 510. In this way, the second telescopic member 521 and the elastic member 522 can provide elastic support for the first guide plate 510, that is, when less coal passes through the guide channel 201, the first guide plate 510 will also buffer the falling coal, and when more coal passes through the guide channel 201, the coal will continuously impact the surface of the first guide plate 510 to allow the first guide plate 510 to rotate around the first hinge shaft 501. At the same time, the elastic member 522 can also play an elastic buffering role for the first guide plate 510, that is, it can be understood that, Figure 3 As shown, when the coal impacts the first guide plate 510, the first guide plate 510 will rotate clockwise along the first hinge shaft 501, and the elastic member 522 connected to the first guide plate 510 can provide the first guide plate 510 with a force to rotate counterclockwise along the first hinge shaft 501. The force of the coal impacting the first guide plate 510 and the elastic member 522 provided to the first guide plate 510 are mutually reactive forces. When the coal passes through the guide channel 201 and no longer impacts the first guide plate 510, the elastic member 522 can elastically reset the first guide plate 510 at this time, so that the first guide plate 510 can maintain an inclined extension state relative to the first section 210. In addition, when When the coal passing through the guide channel 201 is blocked inside the first section 210, the second telescopic member 521 can be contracted to pull the elastic member 522 to drive the first guide plate 510 to move around the first hinge axis 501 toward the inner wall of the first section 210, that is, drive the first guide plate 510 to rotate in the vertical direction. When multiple first guide plates 510 are in a vertical state, the staff can clear the coal blocked in the first section 210. When multiple first guide plates 510 are in a vertical state, the clearability of the coal in the guide channel 201 can be improved, so as to clear the blocked coal in time.

[0030] The second telescopic member 521 mentioned in the above embodiment can also be operated by a hydraulic cylinder in combination with a hydraulic push rod or by a pneumatic telescopic rod. Figure 3 In the embodiment shown, the second telescopic member 521 can adopt a pneumatic telescopic rod, and the pneumatic telescopic rod can be connected to the elastic member 522, so that the elastic member 522 can be driven by the pneumatic telescopic rod to provide elastic support to the first material guide plate 510. In the present disclosure, the elastic member 522 can be a spring.

[0031] In some embodiments, reference Figures 1 to 5As shown, the accommodating cavity 231 is provided with a slide rail (not shown in the figure) extending along the telescopic direction of the second telescopic member 521, and the guide tube 2 also includes a guide assembly 240, and the guide assembly 240 includes a guide rod 241 and a push plate 243. The guide rod 241 is hinged to the first guide plate 510 and slidably connected to the slide rail, and a limit piece 242 is provided on the guide rod 241; the push plate 243 is connected to the elastic member 522 and the output end of the second telescopic member 521; the push plate 243 and the limit piece 242 are constructed so that the push plate 243 can fit the limit piece 242 when the second telescopic member 521 contracts, so as to drive the guide rod 241 to slide along the extension direction of the slide rail. In this way, the guide rod 241 can play a role of guiding and limiting the elastic member 522 when the elastic member 522 supports the first guide plate 510 and drives the first guide plate 510 to swing around the first hinge shaft 501 through the telescopic movement of the second telescopic member 521, that is, it can be referred to. Figure 3 As shown, the number of guide rods 241 is two and they are arranged on two opposite sides of the extension direction of the second telescopic member 521. The number of slide rails can correspond to the number of guide rods 241, which is two. The two slide rails can be arranged at intervals on two opposite sides of the depth direction of the accommodating cavity 231 and slidably connected to the two guide rods 241 in a one-to-one correspondence. In this way, when the first guide plate 510 is impacted by coal and Figure 3 When the second telescopic member 521 is contracted, the push plate 243 can also gradually move into the accommodating chamber 231 with the contraction of the second telescopic member 521. During the movement of the push plate 243, one end surface of the push plate will be attached to the limiting member 242 of the guide rod 241, and the limiting member 242 is pushed by the push plate 243, thereby driving the guide rod 241 to move toward the direction of the accommodating chamber 231, so as to finally pull the first guide plate 510 toward the vertical state, so as to facilitate the subsequent dredging of the coal in the first section 210.

[0032] It should be noted that the stopper 242 may be any suitable structure, for example, Figure 3 and Figure 4 As shown, the limiting member 242 can be a convex block protruding from the guide rod 241 , and the surface of the convex block can be fitted to the end surface of the push plate 243 , so that the convex block is driven to move toward the accommodating cavity 231 under the push of the push plate 243 .

[0033] In some embodiments, reference Figures 1 to 5As shown, the material guiding device further includes a second material guiding mechanism 6 connected to the first section 210 and located at the feed port 211. The second material guiding mechanism 6 includes a second material guiding plate 610 and a driving member 620. The second material guiding plate 610 is connected to the first section 210 and can rotate relative to the feed port 211; the driving member 620 is connected to the second material guiding plate 610, and the driving member 620 is used to drive the second material guiding plate 610 to rotate relative to the feed port 211. In this way, the second material guiding mechanism 6 can guide the coal material that is about to enter the material guiding channel 201 from the feed port 211 through the second material guiding plate 610, that is, it can be referred to Figure 1 As shown, the second guide plate 610 can be driven by the driving member 620 to rotate relative to the feed port 211, so as to control the amount of coal entering from the feed port 211. The second guide plate 610 can be rotated relative to the feed port 211 via a pivot axis (not shown in the figure). Figure 1 In the embodiment, the second guide plate 610 is in a state close to being oriented toward the vertical direction. At this time, the amount of coal that can pass through the feed port 211 is the maximum. When the amount of coal entering needs to be controlled, the second guide plate 610 can be driven to rotate by the driving member 620. For example, the second guide plate 610 can be tilted at a specified preset angle relative to the feed port 211. For example, the second guide plate 610 can be tilted 45°, thereby reducing the rate of coal entering the guide channel 201 from the feed port 211, and reducing the amount of coal entering the guide channel 201 in a short time, thereby gradually reducing the amount of coal discharged from the discharge port 221, thereby reducing the situation where excessive local stacking of coal on the conveyor belt 1 causes uneven stacking of the conveyor belt 1 as a whole.

[0034] It should be noted that the driving member 620 can be constructed as any mechanism that can drive the second guide plate 610 to rotate relative to the feed port 211. For example, the driving member 620 can adopt a driving mode of a driving motor such as a linear motor. Under this driving mode, one end of the second guide plate 610 can be rotatably connected to the inner wall of the first section 210 around the above-mentioned pivot axis, and the output shaft of the linear motor can directly push the second guide plate 610, thereby driving the second guide plate 610 to rotate around the pivot axis to control the amount of coal entering the guide channel 201. In addition, the surface of the second guide plate 610 can also be adopted as Figure 1 The curved plate structure can more easily guide the coal, and the present disclosure does not make any specific limitation on this.

[0035] In some embodiments, reference Figures 1 to 5As shown, the material guiding device also includes a monitoring camera component 7, which is used to monitor the material discharged from the discharge port 221 to the conveyor belt 1. In this way, the monitoring camera component 7 can monitor the coal discharged from the discharge port 221 and transported to the conveyor belt 1 in real time. For example, the real-time pile shape of the coal can be monitored by recording, taking pictures and other functions. The staff can receive the pictures taken or recorded by the monitoring camera component 7 through a remote computer, and determine whether the conveyor belt 1 has uneven coal stacking. The second section 220 can be further rotated relative to the first section 210 to adjust the material drop position. The monitoring camera component 7 can be monitored by a 3D camera or other equipment. For example, you can refer to Figure 1 As shown, the monitoring camera assembly 7 may include a laser irradiation light source 710 and a 3D camera 720. The laser irradiation light source 710 irradiates the conveyor belt 1 to form an irradiation area. When the coal passes through the irradiation area, the 3D camera 720 can capture the outline formed by the coal, and photograph or record the pile shape of the coal, and transmit the photographed model to a remote computer for staff to judge. The method of using a 3D camera and laser irradiation is a well-known technology in the prior art, and the present disclosure will not elaborate on this.

[0036] In some embodiments, reference Figures 1 to 5 As shown, the material guiding device also includes a dust cover 8 covering a portion of the conveyor belt 1, and a discharge space 801 is formed between the dust cover 8 and the conveyor belt 1. The second section 220 passes through the dust cover 8 so that the discharge port 221 is located in the discharge space 801. The dust cover 8 is provided with a discharge port 802 connected to the discharge space 801. In this way, the dust cover 8 can reduce the amount of dust that escapes when the coal falls onto the conveyor belt 1 from the discharge port 221. When the coal is discharged from the discharge port 221, it can enter the discharge space 801 in the dust cover 8, and with the conveyor belt 1, the coal can be discharged from the discharge port 802. In order to further improve the dust-proof effect of the dust cover 8 when the coal is discharged from the discharge port 221, refer to Figure 2 As shown, the dust cover 8 can be attached to the outer wall of the second section 220 through the conical sealing section 803, and the discharge port 221 of the second section 220 can extend into the discharge space 801, thereby achieving a better sealing effect.

[0037] In some embodiments, reference Figures 1 to 5As shown, a concentration sensor 810 and a humidity sensor 820 are provided in the dust cover 8. In this way, the concentration sensor 810 can detect the dust concentration of the coal discharged from the discharge port 221, and the humidity sensor 820 can detect the humidity of the coal discharged from the discharge port 221, so as to better judge whether the coal meets the preset standard. In order to prevent the coal with too high humidity from directly contacting the concentration sensor 810 and / or the humidity sensor 820, so that the coal sticks on the surface of the concentration sensor 810 and / or the humidity sensor 820, resulting in inaccurate detection values ​​or malfunction, refer to Figure 2 As shown, the dust cover 8 can be provided with an outer convex cover 804 for installing a concentration sensor 810 and / or a humidity sensor 820, and the outer convex cover 804 is higher than the upper surface of the dust cover 8, thereby accommodating the concentration sensor 810 and / or the humidity sensor 820, thereby preventing the concentration sensor 810 and / or the humidity sensor 820 from directly contacting the coal material.
