Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of equipment related to conveyor belt machines for coal preparation, specifically to a rotary impurity removal device for a loading belt conveyor. Background Technology
[0002] The belt conveyor (hereinafter referred to as the belt conveyor) in the coal preparation plant is the last checkpoint for loading and transporting coal. During the production process, due to incomplete impurity removal and interception by upstream equipment, impurities may mix into the marketable coal, thus affecting the coal quality.
[0003] like Figure 1 As shown, to ensure coal quality, a debris removal device c is installed at the outlet of the feed port of product bin a on the loading conveyor belt to remove impurities such as wire mesh from the coal. Figure 2-3 As shown, the existing impurity removal device uses steel bar e directly welded to the connecting beam d. The bottom of steel bar e is bent into a hook shape, and several steel bars e are welded onto the connecting beam d. The existing impurity removal device has the following problems: when the belt conveyor b transports material g, large pieces of debris clog and spill i, making it inconvenient to remove debris, and debris is lost. For example... Figure 4 As shown, when the debris-blocking hook f catches a large piece of debris, due to the rigid connection, the large debris will affect the movement of the material g, usually causing spillage. Figure 5 As shown, when the debris hook f catches debris, because conveyor belts are usually tall and wide, after the conveyor belt stops, the inspector cannot easily remove the debris h. They can only climb onto the conveyor belt to remove the debris h, which involves operations such as applying for a power outage, confirming the power outage, locking the button, removing the debris h, unlocking the button, and restoring power to the equipment, which is cumbersome and time-consuming. Figure 6 As shown, in order not to affect the operation of material g, there is a gap between the debris-blocking hooks f. Some smaller debris h and some longitudinally moving debris h will slip away through the gap between the debris-blocking hooks f and cannot be intercepted, thus affecting the coal quality. Summary of the Invention
[0004] The purpose of this invention is to provide a rotary impurity removal device for a vehicle-mounted belt conveyor to overcome the aforementioned shortcomings in the prior art.
[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:
[0006] A rotary impurity removal device for a loading belt conveyor includes a fixed column fixedly installed on one side of the conveyor's intermediate frame, and a rotating column assembly fixedly installed on the other side of the conveyor's intermediate frame opposite to the fixed column. The rotating column assembly includes a base plate fixedly connected to the conveyor's intermediate frame, a base column fixedly installed at the upper end of the base plate, a through hole inside the base column, a rotating column installed in the through hole, a handle on the rotating column, and a crossbeam fixedly installed near the upper end of the rotating column. When the rotating column is rotated, the crossbeam can abut against the side of the fixed column opposite to the coal flow direction. Several sets of impurity blocking hook assemblies are provided at the lower end of the crossbeam.
[0007] Preferably, the debris-blocking hook assembly includes a chain with one end fixedly connected to the crossbeam, and a debris-blocking hook connected to the other end of the chain.
[0008] Preferably, the debris-blocking hook includes three hooks, one end of which is connected to the chain, and the three hooks are evenly distributed in the horizontal direction.
[0009] Preferably, a sphere is provided inside the through hole, and the rotating column is placed on the sphere.
[0010] Preferably, a fixing pin is fixed on the fixing column, and a pin hole is provided on the crossbeam, so that the fixing pin can be inserted into the pin hole.
[0011] Preferably, the handle includes an upward handle and a rotation handle.
[0012] The beneficial effects of this utility model are as follows: 1. The impurity blocking hook of this utility model adopts three hooks evenly distributed on the horizontal plane with small gaps between the hooks, which can reduce the problem of missing impurities, thereby more effectively removing impurities and preventing impurities from entering the product coal and causing coal quality accidents.
[0013] The debris-blocking hook is connected to the crossbeam by a chain. The chain can swing, which prevents the material from being blocked when it catches debris, thus avoiding spillage. At the same time, because the chain and the debris-blocking hook have a certain weight, it can prevent the swing amplitude from being too large, thus preventing the debris from falling off the hook.
[0014] The rotating column allows the debris-blocking hook to be rotated to the maintenance side of the conveyor belt, so that operators no longer need to climb onto the conveyor belt to remove debris, making debris removal more convenient. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0035] According to an embodiment of this utility model, a rotary impurity removal device for a loading belt conveyor is provided, such as... Figure 7-8 As shown, it includes a fixed column 2 welded to one side of the intermediate frame 1 of the conveyor belt, and a fixing pin 14 (e.g., on the side of the fixed column 2 opposite to the coal flow direction) is fixedly provided. Figure 17 As shown), a rotating column assembly is welded to the other side of the intermediate frame 1 of the conveyor belt, at a position relative to the fixed column 2. Figure 16 As shown, the rotating column assembly includes a base plate 3 welded to the intermediate frame 1 of the conveyor belt machine. A base column 4 is welded to the upper end of the base plate 3. The base column 4 has a through hole inside, and a ball 10 is placed inside the through hole. The rotating column 5 is placed on the ball 10 to reduce the coefficient of friction during rotation. The rotating column 5 is equipped with a handle, which includes an upward lifting handle 12 and a rotating handle 13. A crossbeam 6 (such as...) is welded to the upper end of the rotating column 5. Figure 8 As shown), the crossbeam 6 is provided with pin holes. The crossbeam 6 is made of angle steel. When the rotating column 5 is rotated, the crossbeam 6 can be inserted into the fixing pin 14. The lower end of the crossbeam 6 is provided with several sets of debris-blocking hook assemblies.
[0036] like Figure 15 As shown, the debris-blocking hook assembly includes a chain 7 with one end fixedly connected to the crossbeam 6, and a debris-blocking hook 8 connected to the other end of the chain 7. The debris-blocking hook 8 includes three hooks 9, one end of each hook 9 is connected to the chain 7, and the three hooks 9 are evenly distributed in the horizontal direction, that is, each pair of adjacent hooks 9 are arranged at 120 degrees.
[0037] When the tape conveyor is running normally, such as Figure 7-8 As shown, the crossbeam 6 is rotated to be perpendicular to the coal flow direction, and one end of the crossbeam 6 is attached to the fixing pin 14. Due to the movement of the material and the action of the chain 7, the debris-blocking hook 8 will have a certain offset angle with the crossbeam 6 according to the direction of material movement.
[0038] When there is debris on the debris-blocking hook 8, such as Figure 9-10 As shown, the offset angle will be larger, thereby avoiding material blockage and preventing spillage. At the same time, due to the weight of the chain 7 and the hook 8, the offset angle will not be too large, which can prevent the debris from falling off again.
[0039] After the conveyor belt stops, as Figure 11-12As shown, the worker rotates the rotating column 5 to move the debris hook 8 to the side of the conveyor belt. Because the coal preparation plant uses a production organization method where upstream equipment is stopped first, there will be no material on the conveyor belt after it stops. The conveyor belt idler rollers have three sections, all concave in shape, with the highest point of the outermost idler roller being higher than the debris hook 8. Although the debris has moved to the side of the idler roller and the worker can retrieve it, the conveyor belt is energized and could rotate at any time. For safety, the rotating column 5 needs to be lifted and rotated until the debris is rotated out of the conveyor belt, then lowered, and then the debris can be retrieved (e.g., Figure 13-14 In this state, the operation of the conveyor belt will not affect the operator.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
