Description

Technical Field

[0001] The utility model relates to the technical field of coal material transportation devices, and particularly relates to a device for adjusting the coal discharging point of a coal conveying belt. Background Art

[0002] Belt conveyors are commonly used coal conveying equipment. During the production operation process, the upper-level belt conveyor drops coal materials onto the lower-level belt conveyor under the shielding effect of the tail guiding box. Due to the sticking of the guiding box with materials, or different coal material particle sizes, moisture content, and coal conveying volume, the coal discharging point of the tail guiding box is often incorrect. An incorrect coal discharging point will cause the conveyor belt of the lower-level belt conveyor to deviate, resulting in unstable operation of the belt conveyor. Therefore, a device for adjusting the coal discharging point of the coal conveying belt is designed to adjust the coal discharging position of the coal materials on the lower-level belt conveyor.

[0003] There is a device for adjusting the coal discharging point of a coal conveying belt, which includes a counterattack plate assembly. The counterattack plate assembly includes a bottom plate. The tops on both sides of the bottom plate are rotatably connected to the inner wall of the guiding box. The plate surface of the bottom plate facing the tail of the belt conveyor is the front plate surface, and the other plate surface of the bottom plate opposite to the front plate surface is the rear plate surface; the middle of the front plate surface extends and protrudes outward.

[0039] The present utility model provides a device for adjusting the coal feeding belt material falling point, Figures 1 to 4 which is an embodiment of the device for adjusting the coal feeding belt material falling point provided by the present utility model.

[0040] Please refer toFigures 1 to 3 The device for adjusting the coal feeding point of the coal conveying belt includes a belt conveyor 1, a guiding box 2, an adjusting component 3 and a plurality of gathering components 7. Among them, the belt conveyor 1 is used for conveying coal materials, the guiding box 2 is arranged at the tail of the belt conveyor 1, a chute 5 is opened in the guiding box 2, a feeding port is arranged on one side of the chute 5 facing the belt conveyor 1, and the feeding port is communicated with the chute 5 for the belt conveyor 1 to penetrate through the feeding port and extend into the chute 5. And a discharging port for discharging the coal materials is opened at the bottom side of the chute 5. The adjusting component 3 is arranged on the guiding box 2. The adjusting component 3 includes a first driving member 31 and a baffle 32. The baffle 32 is rotatably arranged in the chute 5. The first driving member 31 is arranged on the guiding box 2, and the first driving member 31 is drivingly connected to the baffle 32. The first driving member 31 is used for driving the baffle 32 to rotate closer to or away from the feeding port. The plurality of gathering components 7 are arranged on the baffle 32. The gathering component 7 includes a movable plate 73 and a second driving member 71. The movable plate 73 is rotatably arranged on the baffle 32. The second driving member 71 is arranged in the baffle 32, and the second driving member 71 is drivingly connected to the movable plate 73. The second driving member 71 is used for driving the movable plate 73 to rotate closer to or away from the middle of the baffle 32.

[0041] When using the belt conveyor 1 to convey coal materials, first start the first driving member 31. The first driving member 31 drives the baffle 32 to rotate, changing the inclination angle of the baffle 32. Then start the second driving member 71. The second driving member 71 drives the movable plate 73 to rotate to adjust the inclination angle of the movable plate 73. After the coal materials are transported into the chute 5 in the guiding box 2 by the belt conveyor 1, they fall on the baffle 32 and the movable plate 73. The baffle 32 is used to guide the falling position of the coal materials, so that the coal materials can fall in the direction close to the belt conveyor 1 or in the direction away from the belt conveyor 1. The movable plate 73 is used to concentrate the coal materials, so that the coal materials that deviate towards the side of the belt during the transportation process of the belt conveyor are re-gathered in the middle of the belt. After the coal materials adjust the falling direction under the guidance of the baffle 32 and the movable plate 73, they move towards the falling point through the discharging port at the bottom side of the guiding box 2.

[0042] When there is a height difference during the transportation of coal material, generally, a multi-stage belt conveyor 1 is set up to complete the transportation of coal material from a high place to a low place. Therefore, another belt conveyor 1 is set under the guiding box 2, and the head of this belt conveyor 1 is aligned with the tail of the upper belt conveyor 1. At the same time, the feeding port is directly opposite to the lower belt conveyor 1. The coal material in the guiding box 2 falls onto the lower belt conveyor 1 through the feeding port. With the cooperation of the adjusting assembly 3 and the gathering assembly 7, the coal material will fall on the middle part of this belt conveyor 1, thus avoiding the deviation of the coal material towards the side during transportation, which may cause excessive force on one end of the transmission shaft of the belt conveyor 1 and premature damage.

[0043] Therefore, in the technical solution provided by the present utility model, the adjusting assembly 3 includes a first driving member 31 and a baffle 32. The baffle 32 is rotatably arranged in the chute 5. The first driving member 31 is arranged on the guiding box 2, and the first driving member 31 is drivingly connected to the baffle 32. The gathering assembly 7 includes a movable plate 73 and a second driving member 71. The movable plate 73 is rotatably arranged on the baffle 32. The second driving member 71 is arranged in the baffle 32, and the second driving member 71 is drivingly connected to the movable plate 73, automatically adjusting the inclination angles of the baffle 32 and the movable plate 73, so as to adjust the falling point of the coal material and make the coal material accumulate in the middle of the conveyor during the conveying process.

[0044] The first driving member 31 is used to push the bottom end of the baffle 32 to move closer to or away from the feeding port, thereby changing the angle of the baffle 32. Therefore, a corresponding structure is needed to drive the bottom end of the baffle 32 to move.

[0045] Specifically, in the embodiment of the present utility model, the first driving member 31 includes a cylinder 312, a connecting rod 313, a hinge frame 311 and a limit block 314. The cylinder 312 is arranged on the guiding box 2. The connecting rod 313 is drivingly connected to the cylinder 312. When the cylinder 312 drives the connecting rod 313 to move, it pushes the baffle 32 to rotate. The hinge frame 311 is arranged at the end of the connecting rod 313 away from the cylinder 312. The limit block 314 is arranged on the hinge frame 311, and the limit block 314 is slidably connected in the baffle 32 to limit the movement direction of the hinge frame 311.

[0046] When it is necessary to adjust the inclination angle of the baffle 32, the cylinder 312 is started. The cylinder 312 drives the connecting rod 313 to move closer to or away from the feeding port through the output shaft. The connecting rod 313 drives the limiting block 314 to move together through the hinge frame 311, and pulls the baffle 32 to rotate through the limiting block 314. During the process of driving the baffle 32 to rotate, the limiting block 314 rotates at one end of the connecting rod 313 through the hinge frame 311, so as to cooperate with the rotation of the baffle 32. During the rotation process of the baffle 32, the inclination angle is changed until the baffle 32 rotates to an appropriate inclination angle and then the cylinder 312 is closed. The cylinder 312 can also be replaced by an electric push rod or other devices that can drive the connecting rod 313 to perform linear motion.

[0047] Further, a through hole for the connecting rod 313 to pass through is provided on the right side of the guiding box 2 to limit the moving direction of the connecting rod 313.

[0048] When the cylinder 312 drives the connecting rod 313 to move, the moving direction of the connecting rod 313 should be restricted to ensure that the connecting rod 313 will only move closer to or away from the feeding port under the drive of the cylinder 312, so as to push the bottom end of the baffle 32 to move closer to or away from the feeding port. Therefore, a through hole is provided on the guiding box 2 to limit the moving direction of the connecting rod 313. After the cylinder 312 is started, the connecting rod 313 is driven by the output shaft to move along the extending direction of the through hole. The extending direction of the through hole is set according to the position of the feeding port, so that the connecting rod 313 will only drive the bottom end of the baffle 32 to move closer to or away from the feeding port during the movement, so that the inclination angle of the baffle 32 is changed when it rotates.

[0049] Further, a limiting groove for the sliding connection of the limiting block 314 is provided on the side of the baffle 32 away from the feeding port to limit the moving direction of the limiting block 314.

[0050] When the baffle 32 rotates, the limiting block 314 will also slide on the baffle 32 to cooperate with the movement of the connecting rod 313. The sliding direction of the limiting block 314 needs to be restricted to ensure that the connecting rod 313 can smoothly push the bottom end of the baffle 32 to move closer to or away from the feeding port after moving. Therefore, a limiting groove is provided on the baffle 32 to limit the sliding direction of the limiting block 314, so as to ensure that the bottom end of the baffle 32 can smoothly move closer to or away from the feeding port. At the same time, when the connecting rod 313 pushes the baffle 32 to rotate, the contact position between the connecting rod 313 and the baffle 32 will also change to a certain extent. Through the cooperation of the limiting block 314 and the limiting groove, it is ensured that the bottom end of the baffle 32 can still be pushed to move closer to or away from the feeding port after the contact position between the connecting rod 313 and the baffle 32 changes.

[0051] When the cylinder 312 drives the articulated frame 311 to move in the direction away from the feeding port through the connecting rod 313, it will drive the limit block 314 to move in the direction away from the feeding port, and mobilize the bottom end of the baffle 32 to move together through the limit block 314, and the limit block 314 is slidably connected in the limit groove on the baffle 32. If the limit block 314 wants to drive the baffle 32 to move in the direction away from the feeding port, it is necessary to impose certain restrictions on its shape. The limit block 314 can be set to a step shape, such as an I-shape or a T-shape. The area of the limit block 314 approaching the articulated frame 311 gradually decreases, and the baffle 32 is clearance-matched with the limit block 314 through the limit groove, so that the limit block 314 cannot be separated from the baffle 32, so that when the limit block 314 is driven by the articulated frame 311 to move in the direction away from the feeding port, it can drive the baffle 32 to move together.

[0052] Please also read Figure 4 , the movable plate 73 needs other structural assistance to rotate on the baffle 32. Specifically, in the technical solution of the utility model, the gathering component 7 also includes a rotating shaft 74 and a connecting member 72. The rotating shaft 74 is rotatably connected to the baffle 32, and the rotating shaft 74 is drivingly connected to the second driving member 71. The connecting member 72 is fixed on the rotating shaft 74, and one end of the connecting member 72 away from the rotating shaft 74 is fixed to the movable plate 73, so that when the second driving member 71 drives the rotating shaft 74 to rotate, the movable plate 73 is driven to rotate.

[0053] When it is necessary to rotate the movable plate 73, first start the second driving member 71, and the second driving member 71 drives the rotating shaft 74 to rotate. The rotation of the rotating shaft 74 drives the connecting member 72 to rotate, and drives the movable plate 73 to rotate through the connecting member 72. The movable plate 73 rotates toward the middle of the baffle 32, thereby adjusting the angle between the movable plate 73 and the baffle 32, so that the coal materials biased towards the two sides of the baffle 32 gather toward the middle of the baffle 32, so that the coal materials fall into the middle position of the lower belt conveyor 1 when falling through the drop port, thereby avoiding the coal materials from accumulating on the side of the belt conveyor 1 to cause the drive shaft to be damaged prematurely, and preventing the belt deviation problem of the belt conveyor 1.

[0054] The automatic rotation of the driving shaft 74 requires the cooperation of multiple parts to enable the shaft 74 to rotate or stop at any time. Specifically, in the technical solution of the utility model, the second driving member 71 includes a driving motor 711 and a gear set 712, and the driving motor 711 is arranged on the baffle 32. The gear set 712 is driven and connected to the driving motor 711, and the gear set 712 is fixed on the outside of the shaft 74 to drive the shaft 74 to rotate when the driving motor 711 drives the gear set 712 to rotate.

[0055] After the driving motor 711 is started, it drives the gear set 712 to rotate through the output shaft. While the gear set 712 is rotating, it drives the rotating shaft 74 to rotate. The rotating shaft 74 drives the movable plate 73 to rotate through the connecting member 72. After the movable plate 73 rotates to a suitable position, the driving motor 711 can be turned off. The coal material conveyed on the belt conveyor 1 mainly deviates to the two sides of the belt. Therefore, usually two movable plates 73 are provided. The two movable plates 73 respectively correspond to the two sides of the belt. At the same time, there is not always coal material on both sides of the belt. Therefore, each movable plate 73 can be individually controlled by a driving motor 711. When there is coal material on only one side that needs to be gathered towards the middle, only the driving motor 711 of the movable plate 73 corresponding to this side needs to be started. When there is coal material on both sides that needs to be gathered towards the middle, the two driving motors 711 can be started simultaneously. And according to the different conditions of the deviation of the coal material on each side, the angle that each movable plate 73 needs to rotate is different, that is, the inclination angles of the movable plates 73 are also different. Therefore, each movable plate 73 needs to be individually controlled by a driving motor 711. The staff adjusts the rotation angle of the movable plate 73 according to the specific conditions of the deviation of the coal material on each side to ensure that the coal material can be gathered to the middle.

[0056] Further, a receiving groove for slidably connecting the movable plate 73 is formed on the baffle 32 to limit the baffle 32 from rotating to the side of the baffle 32 away from the material outlet.

[0057] The rotation range of the movable plate 73 needs to be restricted. When the movable plate 73 rotates to the side of the baffle 32 away from the material outlet, it cannot play the role of gathering the coal material. Therefore, it is necessary to prevent the movable plate 73 from rotating to the side of the baffle 32 away from the material outlet. A receiving groove with the same number as the movable plate 73 is provided on the movable plate 73, so that the movable plate 73 will enter the receiving groove during the rotation process. The receiving groove has no opening towards the side away from the material outlet, which makes the movable plate 73 unable to rotate to the side of the baffle 32 away from the material outlet, thus avoiding the problem that the coal material flies to the side of the baffle 32 away from the material outlet and deviates from the falling point.

[0058] Further, the distance between the top side of the baffle 32 and the top wall of the chute 5 is less than one millimeter.

[0059] In order not to hinder the normal rotation of the baffle 32 and the movable plate 73, there needs to be a certain distance between the baffle 32 and the movable plate 73 and the top wall of the chute 5. However, the coal material may fly to the side of the baffle 32 away from the material outlet through the gap between the baffle 32 or the movable plate 73 and the top wall of the chute 5, causing the falling point of this part of the coal material to deviate from the set position. Therefore, the gap between the baffle 32 or the movable plate 73 and the top wall of the chute 5 cannot be too large, and at most only coal dust can pass through, so as to ensure that all the coal material can be restricted by the baffle 32 and fall at the set falling point.

[0060] The baffle 32 cannot rotate in the chute 5 by itself and requires the assistance of other structures. Only then can the baffle 32 complete rotation when the first driving member 31 only pushes the bottom end. Specifically, in the technical solution of the present utility model, a rotating rod 6 is rotatably connected in the chute 5, and the rotating rod 6 is fixed on the baffle 32.

[0061] After the air cylinder 312 is started, when the connecting rod 313 pushes the bottom end of the baffle 32 to move closer to or away from the feeding port, the top end of the baffle 32 is restricted by the rotating rod 6 and cannot move closer to or away from the feeding port. It can only rotate towards the side close to the feeding port or towards the side away from the feeding port under the cooperation of the rotating rod 6, thereby changing the angle between the baffle 32 and the top wall of the chute 5 and changing the inclination angle of the baffle 32. The coal material can fall to different dropping points through the changing inclination angle of the baffle 32.

[0062] The belt of the belt conveyor 1 has a certain elasticity. When the coal material falls from a high place onto the belt, it will be subject to a certain rebound and thus deviate from the dropping point. The higher the height, the greater the rebound force and the farther the deviation. Therefore, it is necessary to re-limit the rebound position of the coal material after dropping to ensure that the coal material also gathers in the middle of the lower belt conveyor 1 after being rebounded. Specifically, in the technical solution of the present utility model, a gathering box 4 is interactively arranged on the bottom side of the guiding box 2. The gathering box 4 is provided with a discharge port for discharging the coal material, and the surface of the gathering box 4 facing away from the guiding box 2 gradually narrows.

[0063] By providing the gathering box 4, the scattering range of the coal material after falling onto the lower belt conveyor 1 is restricted to a certain extent, and the coal material ejected to a relatively far position is blocked so that it cannot scatter to the area outside the middle of the belt. At the same time, the distance between the bottommost side of the gathering box 4 and the lower belt conveyor 1 is controlled within a certain range to prevent the coal material from being ejected through the gap to the outside of the middle of the belt. At the same time, a discharge port is opened on the gathering box 4, and the discharge port is located in the conveying direction of the lower belt conveyor 1, so that the coal material falling onto the lower belt conveyor 1 and located in the gathering box 4 can be transported out of the gathering box 4 and continue to be transported towards the destination. At the same time, the gathering box 4 is arranged in a form with a gradually decreasing area towards the lower belt conveyor 1 to facilitate the coal material accumulated in the gathering box 4 to slide smoothly onto the belt after the coal material at the bottom is transported away, so as to cover the middle of the lower belt conveyor 1 and stably complete the conveying work.

[0064] Meanwhile, since the coal feeding point will change, the gathering box 4 needs to be able to move along with the change of the coal feeding point. The gathering box 4 is movably arranged at the bottom side of the guiding box 2 to be able to move the position of the gathering box 4 to adapt to the changing feeding point. The baffle 32 automatically rotates to change the feeding point through the first driving member 31. Therefore, an automatic moving device also needs to be arranged for the gathering box 4. A linear module is arranged at the bottom side of the guiding box 2, and the gathering box 4 is arranged on the slider of the linear module. When the linear module drives the slider to move, the gathering box 4 can be driven to move. Then, the linear module, the first driving member 31 and the second driving member 71 are electrically connected to the controller, so that the linear module can cooperate with the rotation of the baffle 32 to drive the gathering box 4 to move to complete the adjustment of the feeding point.

[0065] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
