Description

Technical Field

[0001] This utility model relates to the technical field of coal bunker cleaning devices, specifically a high-efficiency coal excavation and cleaning device for coal bunkers. Background Technology

[0002] After raw coal is mined, it needs to be temporarily stored in a coal bunker. During the storage process, due to the storage and deposition of raw coal, a layer of difficult-to-clean deposits will form on the inner wall of the coal bunker. If the coal bunker is not cleaned in time, the effective storage capacity of the coal bunker will be gradually reduced, resulting in poor coal flow and affecting the normal use of the coal bunker.

[0003] Due to the large size of coal bunkers, traditional manual washing and cleaning methods are insufficient for efficient cleaning. Therefore, this application provides a high-efficiency coal excavation and cleaning device for coal bunkers, solving the problem of inconvenient cleaning of deposits on the inner walls of coal bunkers in existing technologies. Utility Model Content

One end of the telescopic arm is rotatably connected to the fixed base. A cleaning claw is connected to the outer end of the telescopic arm. A counterweight arm is provided on the side of the fixed base opposite to the telescopic arm. A support frame is provided between the counterweight arm and the telescopic arm. The support frame is fixedly connected to the counterweight arm. The other end of the support frame is movably connected to the telescopic arm. The telescopic arm is provided with a telescopic cylinder. The movable end of the telescopic cylinder is rotatably connected to the support frame.

[0016] This application uses a hydraulic turntable to drive the telescopic arm to rotate, which enables the cleaning claw to move along the circumference of the coal bunker. After the telescopic arm is extended, the cleaning claw can extend to the vicinity of the inner wall of the coal bunker. The cleaning claw and cleaning components can achieve efficient cleaning of the inner wall of the coal bunker. This application includes a symmetrically arranged telescopic arm and a counterweight arm.

Detailed Implementation

[0025] like Figure 1-5 As shown, a high-efficiency coal mining and cleaning device for a coal bunker includes a fixed base and a telescopic arm 4. One end of the telescopic arm 4 is rotatably connected to the fixed base, and a cleaning claw 13 is connected to the outer end of the telescopic arm 4. A counterweight arm 5 is provided on the side of the fixed base opposite to the telescopic arm 4. A support frame 6 is provided between the counterweight arm 5 and the telescopic arm 4. The support frame 6 is fixedly connected to the counterweight arm 5, and the other end of the support frame 6 is movably connected to the telescopic arm 4. The telescopic arm 4 is provided with a telescopic cylinder 7, and the movable end of the telescopic cylinder 7 is rotatably connected to the support frame 6.

[0026] When the telescopic cylinder 7 is retracted, it can pull the telescopic arm 4 downward to rotate, increasing the radiation range of the device and facilitating efficient cleaning of the inside of the coal bunker. The fixed base drives the telescopic arm 4 to rotate, allowing the cleaning claw 13 to move along the inner wall of the coal bunker, achieving efficient cleaning of the inner wall of the coal bunker.

[0027] like Figure 1 and Figure 6 As shown, the fixed base includes a base body 1 and a rotating part 2. The base body 1 is equipped with a hydraulic motor 3, which is used to drive the rotating part 2 to rotate.

[0028] The telescopic arm 4 and the counterweight arm 5 are connected to each other on both sides of the rotating part 2. The outer end of the counterweight arm 5 is provided with a connecting frame 8, which is used to place the counterweight block 9.

[0029] The length of the counterweight arm 5 is set according to actual usage requirements, and the counterweight block 9 can be a stone or a water tank.

[0030] like Figure 1 and Figure 2 As shown, the support frame 6 is an upward-opening V-shaped frame. One end of the support frame 6 is connected to the outer end of the counterweight arm 5. The telescopic arm 4 is provided with an adjustment groove 10. The other end of the support frame 6 passes through the adjustment groove 10 and is located on the upper side of the telescopic arm 4.

[0031] The support frame 6 has a stop block 11 at its end, and the width of the stop block 11 is greater than the width of the adjustment groove 10.

[0032] The telescopic arm 4 is connected and supported by the telescopic cylinder 7 and the support frame 6 to avoid the telescopic arm 4 affecting the force balance of the fixed seat due to its own weight, and to reduce the wear of the fixed seat.

[0033] The telescopic arm 4 includes several support arms that are rotatably connected end to end. At least one hydraulic cylinder 12 is provided between two adjacent support arms. One end of the hydraulic cylinder 12 is rotatably connected to the middle of the support arm, and the other end of the hydraulic cylinder 12 is connected to the end of the support arm.

[0034] like Figure 1 and Figure 3 As shown, the plurality of support arms include a top support arm and a plurality of connecting arms. The support frame 6 is movably connected to the top support arm, and the cleaning claw 13 is rotatably connected to the outermost connecting arm.

[0035] The top support arm is connected to the support frame 6. Under the action of the telescopic cylinder 7, the top support arm can rotate downward, thereby increasing the cleaning range of the support arm.

[0036] like Figure 1 As shown, a cleaning component is connected to the back of the cleaning claw 13, and a plurality of cleaning teeth 14 are provided at the outer end of the cleaning claw 13.

[0037] The cleaning assembly includes a water supply pipe and a booster pump. The outlet of the booster pump is connected to a distribution pipe, which is connected to a plurality of cleaning pipes 15. The cleaning pipes are laid along the back of the cleaning claws 13, and the outer ends of the cleaning pipes are located between two adjacent cleaning teeth 14.

[0038] The water supply pipe is a flexible hose, which can be installed along the telescopic arm 4, and the end of the cleaning pipe 15 can be connected to a flushing nozzle.

[0039] like Figure 1 As shown, a mounting base 16 is provided in the middle of the support arm, and the end of the hydraulic cylinder 12 is rotatably connected to the mounting base 16. When the hydraulic cylinder 12 extends or retracts, it can pull two adjacent support arms to generate relative rotation.

[0040] In practical use, the fixed base is set at the top center of the coal bunker, and a counterweight 9 is placed at the outer end of the counterweight arm 5 to balance the weight of the telescopic arm 4.

[0041] When the telescopic arm 4 rotates around the base 1, the hydraulic cylinder 12 extends, causing the telescopic arm 4 to extend and the cleaning claw 13 to extend to the inner side wall of the coal bunker. The cleaning claw 13 cleans the deposits on the inner wall of the coal bunker, and at the same time, the cleaning pipe 15 washes the deposits on the inner wall of the coal bunker, improving the cleaning efficiency.

[0042] For areas such as the top and bottom of the coal bunker that are difficult to clean with the telescopic arm 4, the telescopic cylinder 7 can be shortened to pull the telescopic arm 4 downward and rotate it, increasing the operable range of the telescopic arm 4. When the top support arm rotates downward, the cleaning claw 13 can extend upward to clean the top of the coal bunker, or it can extend downward to clean the bottom of the coal bunker.

[0043] The above-described specific embodiments are merely specific examples of this utility model. The patent protection scope of this utility model includes, but is not limited to, the product form and style of the above-described specific embodiments. Any efficient coal bunker excavation and cleaning device that conforms to the claims of this utility model, and any appropriate changes or modifications made to it by a person skilled in the art, shall fall within the patent protection scope of this utility model.
