Description

Technical Field

[0001] The utility model relates to the field of belt conveyors, and particularly to a belt conveyor water scraping device. Background Technique

[0002] A belt conveyor, also known as a belt conveyor, is used to convey loose materials or packaged goods and is widely applied in departments such as mines, metallurgy, and coal. The belt conveyor has the advantages of large conveying capacity, simple structure, convenient maintenance, and standardized components. It can be used alone according to the requirements of the conveying process, or multiple belt conveyors can be combined or composed with other conveying equipment to form a horizontal or inclined conveying system to meet the needs of operation lines with different layout forms. Since the belt conveyor is often in an outdoor working state, after the belt is supported by the idlers, the belt is arranged in an inverted trapezoid, and the center of the belt is sunken and prone to rainwater accumulation; during the process of conveying materials, excessive accumulated rainwater mixed with the conveyed materials will affect the properties of the materials.

[0003] To solve the problem of easy rainwater accumulation in the existing belt conveyor, as described in the existing belt conveyor with the patent number "CN207827273U", a horn-shaped rubber water suction head is connected to a self-priming sewage pump, and the accumulated sewage on the belt is sucked through the water suction head; although this drainage method can suck most of the sewage, since the residual materials on the belt surface are easy to adhere to the belt surface after absorbing water, for such stubborn water-material deposits, the suction force of the conventional water suction head cannot remove them from the belt surface, so it needs to be solved urgently.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-2 , in the embodiment of the present invention, a belt conveyor wiper device is provided. Belt rollers 11 are arranged at intervals along the belt conveying direction on the belt conveyor 1. The belt rollers 11 are the existing inverted trapezoidal rollers with a three-section setting, and the structure will not be described in detail again. They support the belt during the belt running process.

[0028] On the side of the belt of the belt conveyor 1, there is a connecting rod fixing seat 12 located between adjacent belt rollers 11. A second connecting rod 122 is arranged on the connecting rod fixing seat 12. One end of the second connecting rod 122 is hinged with the connecting rod fixing seat 12, and the hinge axis is arranged parallel to the axis of the belt pulley of the belt conveyor 1. The other end of the second connecting rod 122 is provided with a lifting roller 123. The lifting roller 123 is arranged parallel to the belt surface of the middle belt of the belt conveyor. The length of the lifting roller 123 is greater than the length of the belt of the belt conveyor.

[0029] To drive the rotation of the belt roller 11, a first connecting rod 121 fixed to the second connecting rod 122 is also arranged on the connecting rod fixing seat 12. One end of the first connecting rod 121 is coaxially fixed with the rotation point of the second connecting rod 122. The first connecting rod 121 serves as a power source to drive the second connecting rod 122 to rotate synchronously. Each first connecting rod 121 and the second connecting rod 122 form a V-shaped design, and the included angle is preferably an obtuse angle. The first connecting rods 121 are arranged parallel to each other. The driving rod 3 is arranged horizontally along the parallel belt direction. The end of each first connecting rod 121 away from the second connecting rod 122 is hinged with the driving rod 3, and the hinge axis is parallel to the rotation axis of the second connecting rod 122.

[0030] A linear push rod 13 hinged with the belt conveyor 1 is installed on the belt conveyor 1. The hinge axis is parallel to the rotation axis of the second connecting rod 122. The driving end of the linear push rod 13 is hinged with the driving rod 3. The linear push rod 13 drives the driving rod 3 to perform a horizontal linear swinging action to drive the synchronous rotation of each first connecting rod 121. When each first connecting rod 121 rotates, it drives the second connecting rod 122 to rotate synchronously. Under non-wiping operation, the height of the lifting roller 123 at the end of the second connecting rod 122 is lower than the height of the lifting roller 123. Under wiping operation, the height of the lifting roller 123 at the end of the second connecting rod 122 is higher than the height of the lifting roller 123 after rotation, so that the belt changes from an inverted trapezoidal arrangement to a flat arrangement.

[0031] For the convenience of wipering, a third connecting rod 124 is also hingedly arranged on one set of connecting rod fixing seats 12. The third connecting rod 124, the first connecting rod 121 and the second connecting rod 122 are arranged with their rotation axes on the connecting rod fixing seat 12 coinciding, and their ends are coaxially fixed to each other. A wipering frame 2 fixedly connected to the bracket of the belt conveyor 1 is also arranged on the side of the connecting rod fixing seat 12 corresponding to the third connecting rod 124. The top of the wipering frame 2 is an installation position, and the installation position is higher than the maximum movement height of the lifting roller 123. A wipering rod 21 is rotatably arranged at the installation position at the top of the wipering frame 2, and the rotation axis of the wipering rod 21 is parallel to the rotation axis of the second connecting rod 122.

[0032] One end of the wipering rod 21 is provided with a wipering roller 22. The axis of the wipering roller 22 is parallel to the rotation axis of the second connecting rod 122. A counterweight 23 is arranged at the end of the wipering rod 21 away from the wipering roller 22. The distance between the counterweight 23 and the rotation point of the wipering rod 21 is less than the distance between the wipering roller 22 and the rotation point of the wipering rod 21. The end of the third connecting rod 124 away from the connecting rod fixing seat 12 is connected to the wipering rod 21 through a connecting rod 24. The two ends of the connecting rod 24 are respectively hingedly matched with the wipering rod 21 and the third connecting rod 124. The hinge axis is parallel to the rotation axis of the second connecting rod 122, and the hinge point of the connecting rod 24 and the wipering rod 21 is located between the rotation point of the wipering rod 21 and the wipering roller 22.

[0033] When the first connecting rod 121 drives the second connecting rod 122 to rotate, the third connecting rod 124 drives the wipering rod 21 to produce a pitching swing action through the connecting rod 24. The pitching swing direction of the wipering roller 22 is opposite to the rotation direction of the second connecting rod 122. Thus, while the lifting roller 123 lifts the belt, the wipering roller 22 can be pressed downward against the upper surface of the belt, and cooperates with the lifting roller 123 to clamp the belt.

[0034] The wipering roller 22 is a hollow roller. A notch 221 for wipering water is arranged along the length direction of the contact surface between the wipering roller 22 and the belt, and the notch orientation is opposite to the belt conveying direction. A guide rail is arranged along the length direction of the notch 221 of the wipering roller 22 for installing a water storage box 222. There are two groups of water storage boxes 222, symmetrically arranged on both sides of the belt. After sliding and cooperating along the guide rail on the notch 221, they are fixed. The top of the water storage box 222 is open, and the opening is directly below the belt of the belt conveyor 1. The accumulated water scraped by the notch 221 of the wipering roller 22 directly falls into the water storage box 222 along the belt surface.
