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 component or structure itself; "first, second" and the like are 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, a first material guiding mechanism 3 and two second material guiding mechanisms 4. The material guiding pipe 2 forms a material guiding channel 201 inside and includes a feeding port 202 and a discharging port 203, and the discharging port 203 faces the conveyor belt 1; the first material guiding mechanism 3 includes a first driving assembly 310 and a first material guiding plate 320, and the first material guiding plate 320 is rotatably arranged in the material guiding pipe 2 around a pivot axis parallel to the length direction of the conveyor belt 1, and the first driving assembly 310 is used to drive the first material guiding plate 320 to rotate; the second material guiding mechanism 4 includes a first driving assembly 310 and a first material guiding plate 320 located in the material guiding channel. The second material guide plate 410 in the channel 201, the top end of the second material guide plate 410 is connected to the material guide tube 2, the two top ends of the two second material guide plates 410 of the two second material guide mechanisms 4 are respectively located on the opposite sides of the center line of the material guide channel 201, and are symmetrical relative to the vertical plane where the pivot axis is located, the second material guide plate 410 has a first position, in the first position, the second material guide plate 410 extends obliquely from the feed port 202 toward the discharge port 203 and toward the center line of the material guide channel 201, and the projection of the second material guide plate 410 in the horizontal direction covers the first material guide plate 320.

[0021] Through the above scheme, that is, the material guiding device provided by the present disclosure, when the coal is transported through the material guiding device, the coal can enter the material guiding channel 201 from the material inlet 202 of the material guiding pipe 2. When the coal passes through the first material guiding mechanism 3 and the two second material guiding mechanisms 4, it will pass through the gap between the first material guiding plate 320 and the two second material guiding plates 410 extending obliquely, and be discharged to the conveyor belt 1 in the direction of the material outlet 203. The conveyor belt 1 further carries the coal. When the carried coal is piled up in a part of the conveyor belt 1, the first driving component 310 can be used to drive the first material guiding plate 320 to move the coal to the conveyor belt 1. The material plate 320 rotates around the pivot axis, that is, the flow direction of the coal in the material guide channel 201 is guided, so that the amount of coal passing through the gap between the first material guide plate 320 and one of the second material guide plates 410 increases, while the amount of coal passing through the gap between the first material guide plate 320 and the other second material guide plate 410 decreases, thereby changing the position where the coal falls on the conveyor belt 1 when being discharged from the discharge port 203 (for example, it can be toward the position where the conveyor belt 1 is less piled up when transporting coal), so as to reduce the deviation of the conveyor belt 1 caused by uneven material stacking in the width direction of the conveyor belt 1.

[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, and refer to Figure 2 , Figure 3 and Figure 4 As shown, when the coal enters the guide channel 201 from the feed port 202, it passes through the first guide plate 320. Figure 4 When the coal material is in the vertical state, the coal material throughput is the largest. When the coal material on the conveyor belt 1 is unevenly piled, the first guide plate 320 can be driven to rotate around the pivot axis by the first driving assembly 310. For example, Figure 4 The drawing direction in the image can be rotated clockwise or counterclockwise (for example, it can be rotated to Figure 5 The first guide plate 320 is in an inclined position as shown in the figure). When the first guide plate 320 is rotated and fine-tuned, part of the coal will impact the plate surface of the first guide plate 320 and be guided by the first guide plate 320. For example, when the first guide plate 320 rotates clockwise, a Figure 5As shown in the effect, the distance between the top of the first guide plate 320 and the second guide plate 410 on the left is greater than the distance between the top of the first guide plate 320 and the second guide plate 410 on the right, thereby, when the coal falls along the guide channel 201, more coal can enter between the first guide plate 320 and the second guide plate 410 on the left, that is, more coal will be guided to move along the gap between the first guide plate 320 and the second guide plate 410 on the left toward the discharge port 203, and accordingly, the amount of coal passing through the gap between the first guide plate 320 and the second guide plate 410 on the right is reduced, thereby changing the distribution of coal in the width direction of the conveyor belt 1. Similarly, when the first guide plate 320 rotates counterclockwise, the distance between the top of the first guide plate 320 and the second guide plate 410 on the right is greater than the distance between the top of the first guide plate 320 and the second guide plate 410 on the left. As a result, when the coal falls along the guide channel 201, more coal can enter between the first guide plate 320 and the second guide plate 410 on the right, that is, more coal will be guided to move along the gap between the first guide plate 320 and the second guide plate 410 on the right toward the discharge port 203. Accordingly, the amount of coal passing through the gap between the first guide plate 320 and the second guide plate 410 on the left is reduced, which can also change the distribution of coal in the width direction of the conveyor belt 1.

[0023] The first drive component 310 mentioned in the above embodiment can adopt any suitable structure. For example, the first drive component 310 can adopt a suitable method such as a motor with gear transmission or pulley transmission. The present disclosure will describe the first drive component 310 in detail below, so no further details will be given here.

[0024] In some embodiments, reference Figures 1 to 5 As shown, the material guide device also includes a mounting frame 5, and the first driving assembly 310 includes a driving motor 311, a transmission member 312 and a central shaft 313. The driving motor 311 is connected to the mounting frame 5; the transmission member 312 is connected to the output shaft of the driving motor 311; the central shaft 313 is connected to the transmission member 312 and the first material guide plate 320, and the central axis of the central shaft 313 is a pivot axis. In this way, the driving motor 311 drives the transmission member 312 and then drives the central shaft 313 to rotate, which has the advantages of high driving efficiency, fast response speed and precise control. In addition, the transmission member 312 can also be constructed as any suitable structure or component with a transmission function. For example, the transmission member 312 can adopt any suitable method such as gear transmission, belt transmission or worm gear transmission. The disclosure will expand the transmission member 312 in detail below, and no further description is given here.

[0025] In some embodiments, reference Figures 1 to 5As shown, the driving motor 311 and the transmission member 312 are located outside the material guide pipe 2, and the central shaft 313 is disposed through the material guide pipe 2. In this way, the driving motor 311 and the transmission member 312 are located outside the material guide pipe 2, which can prevent the coal from contaminating the driving motor 311 or the transmission member 312 when passing through the material guide channel 201 inside the material guide pipe 2, thereby reducing the occurrence of the driving motor 311 stopping operation due to contamination and the transmission member 312 being unable to transmit due to contamination, and improving the safety of the driving motor 311 and the transmission member 312 running smoothly. The central shaft 313 can pass through the material guide pipe 2 and then be partially located in the material guide channel 201 and connected to the first material guide plate 320. The first material guide plate 320 can rotate with the rotation of the central shaft 313 to guide the coal.

[0026] In some embodiments, reference Figures 1 to 5 As shown, the transmission member 312 includes a first gear 3121 and a second gear 3122, wherein the first gear 3121 is connected to the output shaft of the driving motor 311; the second gear 3122 is meshed with the first gear 3121 and connected to the central shaft 313, and the number of teeth of the second gear 3122 is greater than the number of teeth of the first gear 3121. Through the gear transmission, the output efficiency of the driving motor 311 to the central shaft 313 can be further improved, and the gear transmission also has the advantages of compact structure and large load-bearing capacity. By designing the number of teeth of the second gear 3122 to be greater than the number of teeth of the first gear 3121, the reduction transmission from the driving motor 311, the first gear 3121, the second gear 3122 to the central shaft 313 can be realized, and then the central shaft 313 can be rotated more smoothly, so as to drive the first guide plate 320 to rotate and guide the material more smoothly, and the phenomenon of the first guide plate 320 rotating too fast in a short time and causing the coal material to fly in the guide pipe 2 can be reduced.

[0027] In addition, in the embodiment not shown in the figure, the transmission member 312 is not limited to the above-mentioned two-stage gear transmission method through the first gear 3121 and the second gear 3122, and more stages of gears can also be used to achieve reduction transmission, which is not specifically limited in the present disclosure.

[0028] In some embodiments, reference Figures 1 to 5 As shown, the top end of the second guide plate 410 is hinged to the guide tube 2 through the first hinge shaft 401, and the second guide mechanism 4 also includes a second drive assembly 420, which is connected to the second guide plate 410 and is used to drive the second guide plate 410 to rotate around the first hinge shaft 401. In this way, the second drive assembly 420 can drive the second guide plate 410 to rotate around the first hinge shaft 401, thereby achieving an adjustable angle of the second guide plate 410, for example, referring to Figure 4As shown, when the first guide plate 320 is in a vertical position, the second guide plate 410 can be driven to rotate around the first hinge shaft 401 by the second drive assembly 420. For example, the second drive assembly 420 can drive Figure 4 The second guide plate 410 on the left side rotates counterclockwise around the first hinge shaft 401 on the left side, so that the bottom end of the second guide plate 410 on the left side can be closer to the first guide plate 320, so that the landing point of the coal passing through the gap between the second guide plate 410 on the left side and the first guide plate 320 can be closer to the middle part of the width direction of the conveyor belt 1. Similarly, the second driving assembly 420 can also drive Figure 4 The second guide plate 410 on the right side rotates clockwise around the first hinge shaft 401 on the right side, so that the bottom end of the second guide plate 410 on the right side can be closer to the first guide plate 320, so that the falling point of the coal passing through the gap between the second guide plate 410 on the right side and the first guide plate 320 can be closer to the middle part of the width direction of the conveyor belt 1.

[0029] It should be noted that the second drive component 420 mentioned in the above embodiment can also adopt any suitable component that can drive the second guide plate 410 to rotate around the first hinge axis 401. For example, the second drive component 420 can adopt any suitable drive component such as a hydraulic telescopic rod, a pneumatic telescopic rod or a linear motor. The present disclosure will expand on the second drive component 420 in detail below, so no further details will be given here.

[0030] In some embodiments, reference Figures 1 to 5 As shown, the first guide plate 320 is symmetrically arranged about the central axis 313, and the first guide plate 320 has a vertical position extending in the vertical direction. In the first position, the angle between the second guide plate 410 and the vertical direction is the smallest. In the first position and the vertical position, the top end of the first guide plate 320 is located below the top end of the second guide plate 410, and the bottom end of the first guide plate 320 is located above the bottom end of the second guide plate 410. In this way, when the second guide plate 410 is in the first position, the amount of coal passing through between the two second guide plates 410 is the maximum, and when the second guide plate 410 is in the first position and the first guide plate 320 is in the vertical position, the top end of the first guide plate 320 is located below the top end of the second guide plate 410 and the bottom end of the first guide plate 320 is located above the bottom end of the second guide plate 410, that is, it can be understood that the projection of the second guide plate 410 in the horizontal direction covers the first guide plate 320, so as to adjust the distribution of coal in the width direction of the conveyor belt 1.

[0031] In some embodiments, reference Figures 1 to 5As shown, the second driving assembly 420 includes a telescopic member 421, which is connected to the guide tube 2 and the second guide plate 410. In this way, the telescopic member 421 can drive the second guide plate 410 to rotate around the first hinge shaft 401 by extending or shortening. For example, Figure 4 As shown, the telescopic member 421 can be constructed as a hydraulic telescopic rod, and the two ends of the hydraulic telescopic rod can be hinged to the inner side wall of the guide tube 2 and the second guide plate 410, respectively. In this way, when the hydraulic telescopic rod is extended, the second guide plate 410 can be tilted around the first hinge axis 401 toward the direction close to the center of the guide channel 201. On the contrary, when the hydraulic telescopic rod is shortened, the second guide plate 410 can be tilted around the first hinge axis 401 toward the direction away from the center of the guide channel 201, thereby facilitating the control of the inclination of the second guide plate 410 to achieve different efficiency guide effects on the coal passing through. Alternatively, in an embodiment not shown in the figure, the telescopic member 421 can also be constructed as a spring, a pneumatic telescopic rod or a linear motor, etc.

[0032] In some embodiments, reference Figures 1 to 5 As shown, the guide pipe 2 includes a main pipe 210 and a plurality of sub-pipes 220, and the plurality of sub-pipes 220 are all connected to the main pipe 210. The feed port 202 is provided in the main pipe 210, and the discharge port 203 is provided in the sub-pipe 220. The first guide mechanism 3 and the second guide mechanism 4 are provided in the sub-pipe 220, and the number of conveyor belts 1 is multiple and corresponds to the sub-pipes 220 one by one. In this way, when the coal enters the main pipe 210 from the feed port 202, it can be diverted through the plurality of sub-pipes 220 connected to the main pipe 210. The plurality of batches of diverted coal can also be respectively guided by the first guide mechanisms 3 in the plurality of sub-pipes 220, and then be transferred in batches from the discharge port 203 to the plurality of conveyor belts 1, so that batch transportation of the coal can be realized. For example, Figure 2 In the embodiment shown, there may be two sub-pipes 220, and both sub-pipes 220 may be connected to the main pipe 210, so that when the coal enters the main pipe 210 from the feed port 202, it will be divided into two batches and enter the two sub-pipes 220 respectively, and finally transferred to the two conveyor belts 1. In addition, Figure 2 The two sub-tubes 220 shown in the figure are exemplary. In embodiments not shown in the figure, the sub-tubes 220 may also be other numbers, such as three, four, five or more, and the present disclosure does not make specific limitations on this.

[0033] In some embodiments, reference Figures 1 to 5As shown, the material guiding device also includes a monitoring camera component 6, and the monitoring camera component 6 is used to monitor the material discharged from the material outlet 203 to the conveyor belt 1. In this way, the monitoring camera component 6 can monitor the coal discharged from the material outlet 203 to the conveyor belt 1 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 6 through the remote control computer, and determine whether the conveyor belt 1 has uneven coal stacking. The first guide plate 320 and the second guide plate 410 can be further swung to adjust the falling position of the coal. The monitoring camera component 6 can be monitored by a 3D camera and other equipment. For example, you can refer to Figure 1 As shown, the monitoring camera assembly 6 may include a laser irradiation light source 610 and a 3D camera 620. When the coal passes through the laser irradiation light source 610, the edge of the coal pile will form a clear boundary after being irradiated by the laser irradiation light source 610. Then, the area irradiated by the laser irradiation light source 610, that is, the boundary formed by the coal pile, can be photographed or recorded by the 3D camera 620, and the photographed model can be transmitted to a remote computer for judgment by the staff. The method of identifying objects by 3D cameras and laser irradiation is a well-known technology in the prior art, and the present disclosure will not elaborate on it.

[0034] In some embodiments, reference Figures 1 to 5 As shown, the material guide device also includes a dust cover 7 covering the conveyor belt 1, and a discharge space 701 is formed between the dust cover 7 and the conveyor belt 1. The material guide pipe 2 passes through the dust cover 7 so that the discharge port 203 is located in the discharge space 701. The dust cover 7 is provided with a discharge port 702 connected with the discharge space 701. In this way, the dust cover 7 can reduce the escape of more dust when the coal falls onto the conveyor belt 1 from the discharge port 203. When the coal is discharged from the discharge port 203, it can enter the discharge space 701 in the dust cover 7, and with the conveyor belt 1, the coal can be discharged from the discharge port 702. In order to further improve the dustproof effect of the dust cover 7 when the coal is discharged from the discharge port 203, the discharge port 203 of the material guide pipe 2 can be extended into the discharge space 701, thereby forming a better sealing effect.
