Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of material transportation equipment, and specifically relates to a discharge adjustment device. Background Art
[0002] In current belt conveyors, materials are mostly distributed through hoppers so that they are scattered more evenly on the belt. When the belt fails, or when the material in the hopper is viscous, the material on the belt is prone to uneven distribution. A large amount of material is likely to accumulate under the discharge port in a short period of time, and the material is likely to roll off the belt and fall to the ground, ultimately affecting the operation of the belt conveyor. Summary of the Invention
[0003] In order to solve the technical problem that a large amount of material is easily accumulated under the discharge port of the current belt conveyor in a short period of time, affecting the operation of the belt conveyor, the present application provides a discharge adjustment device.
[0004] In a first aspect of the present application, a discharge adjustment device is provided, comprising:
[0005] A material guide hopper, comprising a material guide plate and connecting pieces provided at both ends of the material guide plate, wherein the two connecting pieces are rotatably connected to the discharging device respectively, so that the material guide plate can be rotatably provided below the discharging port of the discharging device;
[0006] The driving mechanism drives the guide hopper to rotate around the connection between the connecting piece and the discharging device.
[0007] In some embodiments, the material guide plate is in the shape of an arc plate.
[0008] In some embodiments, the connecting member is a connecting plate, and a bottom edge of the connecting plate is connected to a side edge of the guide plate.
[0009] In some embodiments, the driving mechanism comprises:
[0010] Support frame;
[0011] A rotating shaft is rotatably disposed on the support frame, one end of the rotating shaft is fixedly connected to the guide hopper, and the axial direction of the rotating shaft is parallel to the rotational axis of the connecting member;
[0012] A driving member drives the rotating shaft to rotate.
[0013] In some embodiments, the driving member includes a first lever arm and a handle provided at one end of the first lever arm, the other end of the first lever arm is fixedly connected to the other end of the rotating shaft, and the length direction of the first lever arm is perpendicular to the axial direction of the rotating shaft.
[0014] In some embodiments, a second lever arm is provided between the rotating shaft and the guide hopper, the rotating shaft is connected to the guide hopper via the second lever arm, and the length direction of the second lever arm is perpendicular to the axial direction of the rotating shaft.
[0015] In some embodiments, the driving mechanism further includes an extended lever arm, one end of which is rotatably connected to the material guide plate, and the other end of which is rotatably connected to the second lever arm, wherein the length direction of the second lever arm is parallel to the axial direction of the rotating shaft of the connecting shaft.
[0016] In some embodiments, the support frame includes a first bracket and a second bracket, and the rotating shaft is rotatably connected to both the first bracket and the second bracket.
[0017] In some embodiments, the second bracket is located above the extended lever arm, and the rotatable connection between the rotating shaft and the second bracket is located on the bottom wall of the second bracket.
[0018] In some embodiments, a groove is provided on the top of the second bracket, and the width of the second bracket is greater than the width of the extended lever arm.
[0019] The guide plate provided in accordance with one or more embodiments of the present application can control the discharge amount of the discharge port to a certain extent. When the belt stops or slows down and the discharge device fails to respond in time, the guide hopper is driven to rotate by the driving device so that the guide plate is located below the discharge port, thereby blocking or partially blocking the discharge port. When the material is sticky or easy to clump, even if there is a gap between the discharge port and the guide plate, the guide plate can still play a blocking role, thereby adjusting the uniformity of the material distribution on the belt. A large amount of material is not easy to accumulate below the discharge port, and it is not easy to affect the operation of the belt conveyor equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0025] In order to enable those skilled in the art to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.
[0026] See also Figure 1-4 The first embodiment of the present application provides a discharging adjustment device, including a guide hopper 2 and a driving mechanism, wherein the guide hopper 2 is installed at the outlet of a funnel or other discharging equipment to control the discharging condition of the discharging equipment 1.
[0027] The guide hopper 2 includes a guide plate 21 and a connecting piece 22. The connecting piece 22 is provided at both ends of the guide plate 21. The two connecting pieces 22 are rotatably connected to the discharge device 1 so that the guide plate 21 can be rotatably arranged below the discharge port 11 of the discharge device 1. The two connecting pieces 22 are used to connect different ends of the guide plate 21 so that the guide plate 21 can be stably located below the discharge port 11 of the discharge device 1.
[0028] The driving mechanism can drive the guide hopper 2 to rotate around the connection between the connecting piece 22 and the discharge device 1. When the driving mechanism drives the guide plate 21 to block the discharge port 11, the discharge plate can prevent most of the material from falling onto the belt 4.
[0029] The position of the connecting member 22 on the guide plate 21 can be adaptively set according to the shape of the guide plate 21, so that in the natural state, the guide plate 21 is located below the discharge port 11 of the discharge device 1. Furthermore, in the natural state, the vertical projection of the discharge port 11 falls on the guide plate 21. At this time, the material discharged by the discharge device 1 will fall on the guide plate 21, and only a portion of the material will be scattered from the gap between the guide plate 21 and the discharge port 11. In some embodiments, in order to facilitate the rotation of the guide hopper 2 relative to the discharge port 11 of the discharge device 1, the guide plate 21 is in the shape of an arc plate, and the line connecting the connection points of the two connecting members 22 and the discharge device 1 is on the same straight line as an axis of symmetry of the discharge port 11. Among them, the radius of the circle where the curvature of the guide plate 21 is located is consistent with the radius of the guide plate 21 when it rotates, so that when the guide hopper 2 is rotating, the guide plate 21 can be partially located below the discharge port 11. It can be understood that the guide plate 21 can control the discharge amount of the discharge port 11 to a certain extent. When the belt 4 stops or the speed slows down and the discharge device 1 does not respond in time, the guide hopper 2 is driven by the driving device to rotate so that the guide plate 21 is located below the discharge port 11, which can block or partially block the discharge port 11. When the material is sticky or easy to agglomerate, The friction between the materials is large, making them less likely to scatter. Even if there is a gap between the discharge port 11 and the guide plate 21, the guide plate 21 can still serve as a shield. The operator can adjust the opening and closing size between the guide plate 21 and the discharge port 11 by adjusting the drive mechanism. When the opening and closing size is large, more materials are discharged from between the guide plate 21 and the discharge port 11. When the opening and closing size is small, less materials are discharged from between the guide plate 21 and the discharge port 11. This can adjust the distribution effect of the materials discharged from the discharge port 11 on the belt 4, thereby adjusting the uniformity of the materials distributed on the belt 4. As the opening and closing size increases, the inclination angle of the guide plate 21 also increases. Some materials remaining on the surface of the guide plate 21 will also slide down under the action of gravity and eventually fall onto the belt 4.
[0030] In some embodiments, the connecting member 22 is a connecting plate, the bottom edge of which is connected to the side edge of the guide plate 21, and the connecting plate is in the shape of a plate. By connecting the bottom edge of the connecting plate to the side edge of the guide plate 21, the guide plate 21 and the connecting plate are enclosed in a groove-like structure with only front and rear openings. When the material falls on the guide plate 21, the material is restricted by the connecting plate and can only be discharged from the front and rear openings of the guide hopper 2. When installing the guide hopper 2, one of the openings of the guide hopper 2 can be directed towards the direction of the belt 4. While controlling the cloth, the range of the material falling is limited, so that the material is not easy to fall from both sides of the belt 4.
[0031] Specifically, the connecting plate is rotatably arranged on the side wall of the discharge port 11 through a pin shaft, the pin shaft is horizontal and the axial direction of the pin shaft is perpendicular to the moving direction of the belt 4, so that when the guide hopper 2 rotates around the pin shaft, the material discharged from the guide hopper 2 can fall smoothly on the belt 4.
[0032] In some embodiments, the driving mechanism includes a support frame 3, a rotating shaft 33 and a driving member. The support frame 3 is used to support the rotating shaft 33 and the driving member. The rotating shaft 33 is used for transmission. The driving member drives the rotating shaft 33 to rotate, thereby causing the guide hopper 2 to rotate around the connection.
[0033] The rotating shaft 33 is rotatably arranged on the support frame 3, and one end of the rotating shaft 33 is fixedly connected to the guide hopper 2. The axial direction of the rotating shaft 33 is parallel to the axial direction of rotation of the connecting member 22. When the connecting member 22 is connected to the discharge port 11 through the pin shaft, the axial direction of the rotating shaft 33 is parallel to the axial direction of the pin shaft, so that the driving member drives the rotating shaft 33 to rotate and drive the guide hopper 2 to rotate around the pin shaft.
[0034] In some embodiments, the driving member includes a first lever arm 34 and a handle 35 arranged at one end of the first lever arm 34 , the other end of the first lever arm 34 is fixedly connected to the other end of the rotating shaft 33 , and the length direction of the first lever arm 34 is perpendicular to the axial direction of the rotating shaft 33 .
[0035] It can be understood that the driving member is a structural member manually operated by an operator. By providing a first lever 34, the torque is increased and the force required to rotate the rotating shaft 33 is reduced. After the operator grasps the handle 35, he can easily push the rotating shaft 33 to rotate, thereby driving the guide hopper 2 to rotate. Of course, the rotating shaft 33 and the guide hopper 2 can be directly connected or connected through other structural members. For example, in some embodiments, a second lever 36 is provided between the rotating shaft 33 and the guide hopper 2, and the rotating shaft 33 is connected to the guide hopper 2 via the second lever 36. The length direction of the second lever 36 is perpendicular to the axial direction of the rotating shaft 33.
[0036] By setting the second lever arm 36, the force point of the guide hopper 2 can be kept away from the connection between the connecting piece 22 and the discharge device 1, shortening the length of the lever arm between the guide plate 21 and the connection, thereby reducing the force required to drive the guide hopper 2 to rotate, making it easier for operators to adjust the opening and closing size between the guide plate 21 and the discharge port 11.
[0037] In some embodiments, the driving mechanism also includes an extended lever arm 37, one end of which is rotatably connected to the material guide plate 21, and the other end of the extended lever arm 37 is rotatably connected to the second lever arm 36, wherein the length direction of the second lever arm 36 is parallel to the axial direction of the connecting shaft 33.
[0038] Specifically, both ends of the extended lever arm 37 are rotatably connected to the second lever arm 36 and the guide plate 21 via a pin. By providing the extended lever arm 37, the handle 35 can be further away from the guide hopper 2. On the one hand, it can make the operator's operating position further away from the guide hopper 2, improving the operator's safety during operation. On the other hand, the extended arm makes the position of the rotating shaft 33 located obliquely in front of the guide hopper 2. Accordingly, the position where the operator stands when operating the handle 35 is also obliquely in front of the guide hopper 2. The operator can easily see the material situation in the guide hopper 2, which can help the operator determine whether to increase or decrease the opening and closing size between the guide plate 21 and the discharge port 11.
[0039] In some embodiments, the support frame 3 includes a first bracket 31 and a second bracket 32 , and the rotating shaft 33 is rotatably connected to the first bracket 31 and the second bracket 32 .
[0040] As will be appreciated, the rotating shaft 33 is rotatably connected to the first bracket 31 and the second bracket 32. This provides the rotating shaft 33 with two fulcrums, increasing the number of stress points on the rotating shaft 33 and reducing the possibility of deformation of the rotating shaft 33 during use, thereby improving the durability of the rotating shaft 33. Bearings may be provided on both the first bracket 31 and the second bracket 32, and the rotating shaft 33 is connected to the bearings on the first bracket 31 and the second bracket 32 to enable smoother rotation of the rotating shaft 33.
[0041] The first bracket 31 and the second bracket 32 can both be vertical rods, the bottom ends of the vertical rods are fixed to the ground, and a plurality of support rods are obliquely arranged at the lower parts of the vertical rods, so that the first bracket 31 and the second bracket 32 can be stably placed on the ground. Of course, the second bracket 32 can also be a cross bar welded to the side wall of the discharge device 1. In some embodiments, the first bracket 31 and the second bracket 32 can also be connected together by a connecting rod to improve the stability of the entire support frame 3.
[0042] Considering that the extended lever arm 37 is close to the discharging device 1, materials are likely to splash onto the extended lever arm 37. In some embodiments, the second bracket 32 is located above the extended lever arm 37, and the rotatable connection between the rotating shaft 33 and the second bracket 32 is located on the bottom wall of the second bracket 32.
[0043] It can be understood that if the rotating shaft 33 is rotatably connected to the second bracket 32 through a bearing, then the bearing on the second bracket 32 is set on the bottom surface of the second bracket 32 through a bearing seat. At this time, the extended lever arm 37 is at least partially located below the second bracket 32, and the connection between the extended lever arm 37 and the second lever arm 36 and the connection between the rotating shaft 33 and the second bracket 32 can all be located below the second bracket 32, which can prevent material from splashing onto the connection between the extended lever arm 37 and the second lever arm 36 and the connection between the rotating shaft 33 and the second bracket 32, reducing the impact of the material on the driving mechanism, so that the driving mechanism can remain smooth, improving the feel of use and service life.
[0044] In some embodiments, a groove 321 is provided on the top of the second bracket 32 , and the width of the second bracket 32 is greater than the width of the extended lever arm 37 .
[0045] It can be understood that the width of the second bracket 32 is greater than the width of the extended lever arm 37, which can further reduce the probability of material splashing onto the extended lever arm 37, and the groove 321 can collect the material dropped on the second bracket 32, so that the material is not easy to fall from the second bracket 32 for a second time and affect the driving mechanism, and the operator only needs to clean it regularly.
