Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for bucket wheel reclaimers, specifically a self-adjusting cleaner. Background Technology

[0002] The double-tail bucket wheel stacker-reclaimer requires switching the belt conveyor mode during stacking and reclaiming because the feed tail car is mobile. Currently, the scraper is fixed. During mode switching, due to precision issues, the scraper blades cannot properly engage with the belt, resulting in significant material carryback on the belt and causing considerable inconvenience for users. Utility Model Content

[0003] The purpose of this utility model is to provide a self-adjusting sweeper to solve the problem mentioned in the background art that the current sweepers are fixedly installed, and the cooperation between the sweeper scraper and the belt cannot be guaranteed, resulting in serious material carrying on the belt during return.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a self-adjusting sweeper, comprising two opposing fixed supports, wherein a sweeping mechanism movable up and down is provided at the top of the fixed supports for sweeping materials; a pushing mechanism is installed at the bottom of the fixed supports for driving the sweeping mechanism to move up and down; and a positioning sensing mechanism is provided between the pushing mechanism and the sweeping mechanism for sensing the position when the pushing mechanism drives the sweeping mechanism to move.

[0005] Preferably, the positioning sensing mechanism includes a proximity switch and a sensing frame. The proximity switch is detachably mounted on the surface of the fixed bracket, and the sensing frame is integrally injection molded on the surface of the sensing frame. The sensing frame and the proximity switch work together to sense the positioning when the cleaning mechanism rises.

[0006] Preferably, the pushing mechanism includes an electric push rod and a movable bracket, wherein the electric push rod is fixedly connected to the bottom end of the fixed bracket.

[0007] Preferably, a movable bracket is slidably connected to the surface of the fixed bracket, and the bottom end of the movable bracket is fixedly connected to the output end of the electric push rod.

[0008] Preferably, the cleaning mechanism includes a rotating rod, a cleaner, an alloy steel mold spring, and a cleaner mounting base. Two cleaner mounting bases are provided, and the two cleaner mounting bases are slidably connected to the surfaces of two movable supports.

[0009] Preferably, a rotating rod is installed between two adjacent cleaner mounting bases, and a cleaner is fixed to the top of the rotating rod for cleaning materials.

[0010] Preferably, an alloy steel mold spring is fixedly connected to the bottom of the cleaner mounting base, and the bottom end of the alloy steel mold spring is fixedly connected to the surface of the sensing frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In the non-working state, the electric push rod of this self-adjusting sweeper is at its lower limit. When the bucket wheel excavator is in the material-stacking state, a signal is given after the tail car reaches its position and the hook is engaged. The electric push rod then provides power to press the sweeper onto the belt. The compression stroke is calculated based on the compression rate of the alloy steel mold spring and the required preload. When the stroke is reached, a proximity switch provides a signal, and the electric push rod stops advancing and remains stationary. The preload can be adjusted by replacing the alloy steel mold spring and adjusting the proximity switch position as needed. When the bucket wheel excavator is in the material-retrieving state, a signal is given when the tail car hook engages, and the electric push rod retracts to its lower limit and remains stationary. When the electric push rod contacts the upper limit switch, it indicates a problem with the sweeper, such as the scraper exceeding its wear range or structural deformation. The machine must be stopped immediately for inspection to avoid damage. This sweeper is adjustable, ensuring proper coordination between the scraper scraper and the belt, preventing material from being carried back onto the belt. The limit switch and proximity switch provide warnings when the scraper exceeds its wear range or structural deformation occurs, preventing equipment damage. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. In addition, the terms "first", "second", "third", "upper", "lower", "left", "right", etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance. At the same time, in the description of the present utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0019] The structure of the self-adjusting sweeper provided by this utility model is as follows: Figure 1 as well as Figure 4 As shown, the device includes two opposing fixed supports 1. The top of the fixed supports 1 is equipped with a cleaning mechanism 2 that can move up and down. The cleaning mechanism 2 is used for cleaning materials. The cleaning mechanism 2 includes a rotating rod 21, a cleaner 22, an alloy steel mold spring 23, and a cleaner mounting base 24. There are two cleaner mounting bases 24, which are slidably connected to the surfaces of two movable supports 32. A rotating rod 21 is installed between two adjacent cleaner mounting bases 24, and a cleaner 22 is fixed to the top of the rotating rod 21. The cleaner 22 is used for cleaning materials. The cleaner includes a scraper, a scraper seat, and a connecting piece. The connecting piece is welded to the rotating rod 21, and the scraper seat is fixed to the surface of the connecting piece by screws. The scraper is fixed to the scraper seat by screws.

[0020] In practice, the self-adjusting sweeper of this utility model is installed on the relay belt guide chute support, and is installed perpendicular to the return belt of the tail car.

[0021] Furthermore, such as Figure 2 as well as Figure 4 As shown, a pushing mechanism 3 is installed at the bottom of the fixed bracket 1. The pushing mechanism 3 is used to drive the cleaning mechanism 2 to move up and down. The pushing mechanism 3 includes an electric push rod 31 and a movable bracket 32. The electric push rod 31 is fixedly connected to the bottom end of the fixed bracket 1. Limit switches are installed at both the upper and lower ends of the electric push rod 31. The movable bracket 32 ​​is slidably connected to the surface of the fixed bracket 1, and the bottom end of the movable bracket 32 ​​is fixedly connected to the output end of the electric push rod 31.

[0022] When the bucket wheel excavator is in the material handling state, the tail car hook contacts the signal, and the electric push rod 31 retracts to the lower limit and remains stationary. When the electric push rod 31 contacts the upper limit switch, it indicates that there is a problem with the cleaner 22, such as the scraper exceeding the wear range or structural deformation. It is necessary to stop the machine in time for inspection to avoid damaging the equipment.

[0023] Furthermore, such as Figure 3 as well as Figure 4 As shown, a positioning sensing mechanism 4 is provided between the pushing mechanism 3 and the cleaning mechanism 2. The positioning sensing mechanism 4 is used for positioning sensing when the pushing mechanism 3 drives the cleaning mechanism 2 to move. The positioning sensing mechanism 4 includes a proximity switch 41 and a sensing frame 42. The proximity switch 41 is detachably mounted on the surface of the fixed bracket 1. The sensing frame 42 is integrally injection molded on the surface of the sensing frame 42. The sensing frame 42 and the proximity switch 41 cooperate to perform positioning sensing when the cleaning mechanism 2 rises. An alloy steel mold spring 23 is fixedly connected to the bottom of the cleaner mounting base 24, and the bottom end of the alloy steel mold spring 23 is fixedly connected to the surface of the sensing frame 42.

[0024] When the self-adjusting sweeper 22 of this invention is not in operation, the electric push rod 31 is at its lower limit position. When the bucket wheel excavator is in the stacking state, a signal is given after the tail car reaches its hook, and the electric push rod 31 begins to provide power, pressing the sweeper 22 onto the belt. The compression stroke is calculated based on the compression rate of the alloy steel mold spring 23 and the required preload. When the stroke is complete, the proximity switch 41 provides a signal, and the electric push rod 31 stops advancing and remains stationary. The preload can be adjusted by replacing the alloy steel mold spring 23 and adjusting the position of the proximity switch 41 as needed.

[0025] Working principle: When in use, the self-adjusting sweeper of this utility model is installed on the relay belt guide chute bracket, and it is installed perpendicular to the return belt of the tail car.

[0026] When the self-adjusting sweeper 22 of this invention is not in operation, the electric push rod 31 is at its lower limit position. When the bucket wheel excavator is in the stacking state, a signal is given after the tail car reaches its hook, and the electric push rod 31 begins to provide power, pressing the sweeper 22 onto the belt. The compression stroke is calculated based on the compression rate of the alloy steel mold spring 23 and the required preload. When the stroke is complete, the proximity switch 41 provides a signal, and the electric push rod 31 stops advancing and remains stationary. The preload can be adjusted by replacing the alloy steel mold spring 23 and adjusting the position of the proximity switch 41 as needed.

[0027] When the bucket wheel excavator is in the material handling state, the tail car hook contacts the signal, and the electric push rod 31 retracts to the lower limit and remains stationary. When the electric push rod 31 contacts the upper limit switch, it indicates that there is a problem with the cleaner 22, such as the scraper exceeding the wear range or structural deformation. It is necessary to stop the machine in time for inspection to avoid damaging the equipment.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
