Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, in particular to a mechanical vibration device for a trough-type belt conveyor. Background Art

[0002] Trough belt conveyors can transport bulk materials with higher specific gravity such as coal, ore, soil, chemical raw materials, and grains. They are suitable for relatively harsh production environments and have functions such as dirt resistance and wear resistance. Due to the reasons for transporting materials, the surface of the trough box of the trough belt conveyor will stick to it during the transportation process, wasting materials and consuming manpower to clean.

[0003] The idler is a basic component of the trough belt conveyor. During the working process of the trough belt conveyor, it mainly supports the materials on the belt. The idlers include iron idlers, ceramic idlers, rubber idlers, etc. The existing idlers can only play a supporting role. Utility Model Content

[0004] The purpose of this utility model is to provide a mechanical vibration device for a trough belt conveyor to solve the problems of the existing trough belt conveyor rollers sticking to the bottom of the materials and easily scattering on the ground, which consumes manpower to clean up. The utility model provides the following technical solutions:

[0005] A mechanical vibrating device for a trough belt conveyor includes a roller, a roller bracket and a vibrating round steel. An elastic reset device is provided between the roller and the roller bracket. The roller is rotatably mounted on the bottom of the elastic reset device. The vibrating round steel is arranged on the surface of the roller and is arranged parallel to the axial direction of the roller.

[0006] The elastic reset device includes a telescopic spring, a mounting plate for mounting the top of the telescopic spring, and a bearing mounted at the bottom of the telescopic spring. The mounting shafts at both ends of the roller are rotatably mounted at the bottom of the telescopic spring through the bearings.

[0007] The roller bracket is provided with a guide device, which is installed on both sides of the bearing.

[0008] The guide device comprises a guide rod, which is arranged perpendicular to the axial direction of the roller. A sliding sleeve is arranged on the guide rod, and the sliding sleeve is fixedly connected to the side surface of the bearing through a connecting rod.

[0009] The top of the guide rod is fixed on the roller bracket, and the bottom of the guide rod is provided with a limit block, which is matched with the limit rod thread.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The utility model forms mechanical vibration through the intermittent knocking of the vibrating round steel on both sides and the elastic force of the telescopic spring. Compared with the traditional roller, it can not only support the belt but also add the intermittent vibration function, thereby solving the problem of material sticking at the bottom of the trough box during the material transportation by the trough belt; the material on the belt surface and the bottom of the trough box is knocked into the material collection trough for reuse through the vibration method, which improves the utilization rate of the material and reduces the workload of cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is the front view of the utility model;

[0013] Figure 2 It is a side view of the utility model.

[0014] In the above drawings, there are roller 1, roller bracket 2, vibrating round steel 3, elastic reset device 4, belt 5, trough box 6, telescopic spring 4-1, mounting plate 4-2, bearing 4-3, guide device 7, guide rod 7-1, sliding sleeve 7-2, connecting rod 8, mounting shaft 9, and limit block 10. DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0016] like Figure 1-2 As shown, the mechanical vibrating device of the trough belt 5 conveyor provided by the utility model includes a roller 1, a roller bracket 2 and a vibrating round steel 3. An elastic reset device 4 is arranged between the roller 1 and the roller bracket 2. The roller 1 contacts the belt 5 of the trough belt 5 conveyor on the lower surface to support the belt 5. The roller 1 is rotatably installed at the bottom of the elastic reset device 4, and the vibrating round steel 3 is arranged on the surface of the roller 1. The vibrating round steel 3 is arranged parallel to the axial direction of the roller 1. During the rotation of the belt 5, the friction force is used to drive the vibrating round steel 3 to rotate with the roller 1. When the vibrating round steel 3 contacts the belt 5, the belt 5 is vibrated, and the trough box 6 and the surface of the belt 5 on the belt 5 are vibrated, so that the material adhered to the trough box 6 and the surface of the belt 5 is shaken off, and the elastic reset device 4 cooperates to retract and retract during the rotation of the roller 1 and the vibrating round steel 3.

[0017] The elastic reset device 4 includes a telescopic spring 4-1, a mounting plate 4-2 for mounting the top of the telescopic spring 4-1, and a bearing 4-3 mounted at the bottom of the telescopic spring 4-1. The mounting plate 4-2 is fixed to the top of the roller bracket 2. The mounting shafts 9 at both ends of the roller 1 are rotatably mounted on the bottom of the telescopic spring 4-1 through the bearings 4-3. The bearings 4-3 allow the roller 1 to rotate smoothly at the bottom of the telescopic spring 4-1, thereby reducing the rotational resistance of the roller 1.

[0018] The roller bracket 2 is provided with a guide device 7, which is installed on both sides of the bearing 4-3. The guide device 7 determines the moving direction of the roller 1, and the roller 1 only moves vertically back and forth at the place where the belt 5 is vibrating.

[0019] The guide device 7 includes a guide rod 7-1, which is arranged axially perpendicular to the roller 1. A sleeve 7-2 is provided on the guide rod 7-1. The sleeve 7-2 is fixedly connected to the side of the bearing 4-3 through a connecting rod 8. The sleeve 7-2, the bearing 4-3 and the mounting shaft 9 in the bearing 4-3 move synchronously with the roller 1. The sleeve 7-2 slides on the guide rod 7-1 and guides the movement of the roller 1 through the slider.

[0020] The top of the guide rod 7-1 is fixed on the roller bracket 2, and a limit block 10 is set above the sliding sleeve 7-2 on the guide rod 7-1. The limit block 10 is threaded with the limit rod, and the position of the limit block 10 is adjustable. By properly controlling the position of the limit block 10, the lowest position of the roller 1 and the vibrating round steel 3 can be limited, so that the roller 1 and the vibrating round steel 3 always have pressure on the belt 5 without causing strain on the belt 5 due to the transition support of the belt 5.

[0021] The roller 1 in the utility model is a carbon steel cylinder of Φ110mm×950mm; the rapping round steel 3 is a steel material of φ14×950mm; the roller bracket 2 and the mounting plate 4-2 are welded steel plates with a thickness of 20; the telescopic spring 4-1 is Φ4*12*60*10N, and the total length of the mechanical rapping device is 1090mm.

[0022] When the material in the belt 5 trough box 6 is normally transported to the discharge port, it is automatically dumped into the hopper. However, since the material contains a certain amount of moisture, it is easy to stick to the bottom of the belt 5 trough box 6. When the belt 5 trough box 6 is unloaded, it rotates back to the vibrating device. The roller 1 in the mechanical vibrating device rotates with the belt 5, and the elastic force of the vibrating round steel 3 on both sides and the telescopic spring 4-1 intermittently knocks to form mechanical vibration, thereby solving the problem of material sticking to the bottom of the trough box 6 during the material transportation process of the trough belt 5; the materials on the surface of the belt 5 and the bottom of the trough box 6 are knocked into the material collection tank for reuse through vibration, which improves the utilization rate of the material, reduces the workload of cleaning and sanitation, and adds an intermittent vibrating function compared with traditional rollers.
