Description

Technical Field

[0001] The invention relates to the technical field of coal placing in a coal bunker, and in particular to a coal bunker lower locking opening and multiple coal placing opening device. Background Art

[0002] The lower lock is a device used in the coal mining industry, mainly used to solve various problems that may occur when releasing coal from the lower opening of the coal bunker, such as blockage, poor coal release, etc. It is used to improve coal transportation efficiency, reduce manual intervention, reduce safety hazards, and extend the service life of the coal bunker.

[0003] At present, in order to meet the falling needs of coal blocks of different sizes, multiple coal nozzles with different leakage sizes are set in the lower locking mouth. However, in actual application, a larger coal block may fall onto a coal nozzle with a smaller leakage size, which will cause the coal block to be stuck at the coal nozzle, thus affecting the falling of the coal block. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a device for multiple coal outlets under a coal bunker with a locking mouth. The device can remove coal blocks stuck on the coal outlet mouth with a small spacing between spokes through a rotating coal sweeping assembly, effectively avoiding a series of problems caused by coal block accumulation, thereby ensuring that the coal blocks fall normally to the bottom of the coal bunker.

[0005] To solve the above technical problems, the technical solution of the present invention is achieved as follows:

[0006] A coal bunker lower lock multiple coal outlet device, the device is integrally erected and fixed on the top of the coal bunker, and comprises a lower lock coal outlet platform assembly, the lower lock coal outlet platform assembly comprises a coal outlet platform, and the coal outlet platform is provided with multiple coal outlets distributed in a circumferential array;

[0007] Each coal leakage opening is equipped with a coal leakage nozzle coal dropping assembly, the coal leakage nozzle coal dropping assembly includes a coal leakage nozzle, and a plurality of linear array-distributed spaced spokes are fixedly installed at the opening of the coal leakage nozzle;

[0008] The spacing between spokes in all coal leaking nozzles increases or decreases in a clockwise or counterclockwise direction with the coal leaking platform as the center;

[0009] A rotary coal sweeping assembly is installed at the center of the leaky coal platform. The rotary coal sweeping assembly includes a main coal sweeping rotary rod. The main coal sweeping rotary rod is driven to rotate by a motor fixedly installed at the bottom of the leaky coal platform. A plurality of auxiliary coal sweeping straight rods distributed in a linear array along its length are vertically fixed below the main coal sweeping rotary rod. The bottom ends of the auxiliary coal sweeping straight rods just touch the upper surface of the leaky coal platform.

[0010] By adopting the above scheme, the device drives the main coal-sweeping rotary rod to rotate through motor 1. When the main coal-sweeping rotary rod rotates, it can move the coal blocks stuck on the coal leakage nozzle with a small spacing between the spokes through the auxiliary coal-sweeping straight rod, effectively avoiding a series of problems caused by coal block accumulation, thereby ensuring that the coal blocks fall normally to the bottom of the coal bin.

[0011] As a preferred implementation of a multiple-coal-release device with a locking opening under a coal bunker, the bottom end of the auxiliary coal-sweeping straight rod is a smooth round head.

[0012] By adopting the above scheme, in order to reduce the friction between the auxiliary coal sweeping straight rod and the coal leakage platform, the bottom end of the auxiliary coal sweeping straight rod is rounded, which can reduce the friction between the two and thus reduce the driving load of motor 1.

[0013] As a preferred implementation of a multiple coal-release opening device with a locking opening under a coal bunker, a plurality of intercepting rods parallel to the main coal-sweeping rotary rod are fixed on the side wall of the auxiliary coal-sweeping straight rod.

[0014] By adopting the above scheme, in order to further improve the "escape ability" of the coal blocks on the spaced spokes, an intercepting rod is added to further increase the contact area between the intercepting rod and the coal blocks, thereby better driving the coal blocks to move.

[0015] As a preferred implementation of a multiple coal-release opening device with a lower locking opening in a coal bunker, both ends of the main coal-sweeping rotary rod are respectively slidably installed in an annular slideway.

[0016] By adopting the above scheme, in order to assist the rotation of the main coal sweeping rotary rod, an annular slideway is provided to assist the rotation of the main coal sweeping rotary rod, so that the main coal sweeping rotary rod has better balance during rotation.

[0017] As a preferred embodiment of a multi-coal outlet device with a lower locking mouth in a coal bunker, the side ears of the coal leakage nozzle are slidably mounted on a guide shaft fixed to the bottom of the coal leakage platform, and the guide shaft is provided with springs one and two which are respectively located above and below the side ears of the coal leakage nozzle; one side of the coal leakage nozzle is matched with an L-shaped frame fixed to the bottom of the coal leakage platform, and motor two is mounted on the L-shaped frame, and a cam is concentrically connected to the rotating shaft of motor two, and a vertically arranged upper support rod is mounted above the cam, and the upper support rod is detachably fixed to the side ears of the coal leakage nozzle through a connecting seat; the lower end of the upper support rod is a smooth round head; and only one protrusion or two mutually symmetrical protrusions are fixed on the cam.

[0018] By adopting the above scheme, in order to promote the rapid fall of coal blocks from the spaced spokes, the cam is driven to rotate by motor 2, and the protrusion on the cam is used to continuously resist the upper support rod to move upward. After each movement, it automatically falls under the action of its gravity, thereby realizing the reciprocating vibration of the coal nozzle up and down, thereby promoting the rapid fall of coal blocks from the spaced spokes.

[0019] As a preferred implementation of a coal bunker lower locking and multiple coal-releasing opening device, the bottom of the coal leakage platform also supports and fixes crisscrossed channel steels 1 and 2.

[0020] By adopting the above scheme, in order to improve the stability of the coal leakage platform, channel steel 1 and channel steel 2 are added to support the bottom thereof, thereby improving the stability and reliability of the coal leakage platform.

[0021] After adopting the above technical solution, the beneficial effects of the present invention are:

[0022] 1. The device drives the main coal sweeping rotary rod to rotate through a motor. When the main coal sweeping rotary rod rotates, it can move the coal blocks stuck on the coal leakage nozzle with a small spacing between the spokes through the auxiliary coal sweeping straight rod, effectively avoiding a series of problems caused by the accumulation of coal blocks, thereby ensuring that the coal blocks fall normally to the bottom of the coal bunker;

[0023] 2. In order to reduce the friction between the auxiliary coal sweeping rod and the coal leakage platform, the bottom end of the auxiliary coal sweeping rod is rounded to reduce the friction between the two, thereby reducing the driving load of the motor;

[0024] 3. In order to further improve the "escape ability" of coal blocks on the spaced spokes, interceptor rods are added to further increase the contact area between them and the coal blocks, thereby better driving the coal blocks to move;

[0025] 4. In order to assist the rotation of the main coal sweeping rotary rod, an annular slideway is provided to assist the rotation of the main coal sweeping rotary rod, so that the main coal sweeping rotary rod has better balance during rotation;

[0026] 5. In order to promote the rapid drop of coal from the spaced spokes, the cam is driven to rotate by the second motor, and the protrusion on the cam is used to continuously resist the upper support rod to move upward. After each movement, it automatically falls under the action of gravity, thereby realizing the reciprocating vibration of the coal nozzle, thereby promoting the rapid drop of coal from the spaced spokes;

[0027] 6. In order to improve the stability of the coal leakage platform, channel steel 1 and channel steel 2 are added to support its bottom, thereby improving the stability and reliability of the coal leakage platform. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] like Figures 1 to 10 As shown, a coal bunker lower lock multiple coal outlet device, the device is integrally erected and fixed on the top of the coal bunker 3, and comprises a lower lock coal outlet platform 1 component, the lower lock coal outlet platform 1 component comprises a coal outlet platform 1, and the coal outlet platform 1 is provided with a plurality of coal outlets 2 distributed in a circumferential array; each coal outlet 2 is provided with a coal outlet nozzle 4 coal dropping component, the coal outlet nozzle 4 coal dropping component comprises a coal outlet nozzle 4, and a plurality of spaced spokes 5 distributed in a linear array are fixedly installed at the opening of the coal outlet nozzle 4; the spaced spokes 5 inside all the coal outlet nozzles 4 are The spacing of the strips 5 increases or decreases in a clockwise or counterclockwise direction with the coal leakage platform 1 as the center; a rotary coal sweeping assembly is installed at the center of the coal leakage platform 1, and the rotary coal sweeping assembly includes a main coal sweeping rotary rod 6, which is driven to rotate by a motor 7 fixedly installed at the bottom of the coal leakage platform 1, and a plurality of auxiliary coal sweeping straight rods 8 distributed in a linear array along its length are vertically fixed below the main coal sweeping rotary rod 6, and the bottom ends of the auxiliary coal sweeping straight rods 8 just contact the upper surface of the coal leakage platform 1. The device drives the main coal sweeping rotary rod 6 to rotate through the motor 7, and the main coal sweeping rotary rod 6 can move the coal blocks stuck on the coal leakage nozzle 4 with a smaller spacing between the spokes 5 through the auxiliary coal sweeping straight rods 8 when rotating, effectively avoiding a series of problems caused by the accumulation of coal blocks, thereby ensuring that the coal blocks fall normally to the bottom of the coal bin 3.

[0042] like Figure 6 As shown, the bottom end of the auxiliary coal sweeping straight rod 8 is a smooth round head. In order to reduce the friction between the auxiliary coal sweeping straight rod 8 and the coal leakage platform 1, the bottom end of the auxiliary coal sweeping straight rod 8 is rounded, which can reduce the friction between the two, thereby reducing the driving load of the motor 7.

[0043] like Figure 6 As shown, a plurality of intercepting rods parallel to the main coal sweeping rotary rod 6 are fixed on the side wall of the auxiliary coal sweeping straight rod 8. In order to further improve the "escape ability" of the coal blocks on the spaced spokes 5, the contact area between the intercepting rods and the coal blocks is further increased by adding intercepting rods, thereby better driving the coal blocks to move.

[0044] like Figure 5 As shown, both ends of the main coal sweeping rotary rod 6 are slidably installed in the annular slideway 10. In order to assist the rotation of the main coal sweeping rotary rod 6, the annular slideway 10 can assist the rotation of the main coal sweeping rotary rod 6, so that the main coal sweeping rotary rod 6 has better balance during rotation.

[0045] like Figures 7 to 10As shown, the side ear of the coal leakage nozzle 4 is slidably mounted on a guide shaft 11 fixed to the bottom of the coal leakage platform 1, and the guide shaft 11 is sleeved with a spring 12 and a spring 2 13 respectively located above and below the side ear of the coal leakage nozzle 4; one side of the coal leakage nozzle 4 is matched with an L-shaped frame 14 fixed to the bottom of the coal leakage platform 1, and a motor 2 15 is installed on the L-shaped frame 14, and a cam 16 is concentrically connected to the rotating shaft of the motor 2 15, and a vertically arranged upper support rod 17 is installed above the cam 16, and the upper support rod 17 is detachably fixed to the side ear of the coal leakage nozzle 4 through a connecting seat 18; the lower end of the upper support rod 17 is a smooth round head; only one protrusion 19 or two mutually symmetrical protrusions 19 are fixed on the cam 16. In order to promote the rapid drop of coal blocks from the spaced spokes 5, the cam 16 is driven to rotate by the motor 2 15, and the protrusion 19 on the cam 16 continuously resists the upper support rod 17 to move upward. After each movement, it automatically falls under the action of its gravity, thereby realizing the reciprocating vibration of the coal nozzle 4 up and down, thereby promoting the rapid drop of coal blocks from the spaced spokes 5.

[0046] like Figure 3 to Figure 4 As shown, the bottom of the leakage coal platform 1 is also supported and fixed with crisscrossed channel steel 1 20 and channel steel 2 21. In order to improve the stability of the leakage coal platform 1, the bottom is supported by adding channel steel 1 20 and channel steel 2 21, thereby improving the stability and reliability of the leakage coal platform 1.

[0047] Working principle of the present invention:

[0048] Crushed coal blocks are transported from the top of the coal bunker 3 , wherein the volume of the coal blocks after crushing is smaller than the maximum spacing of the spaced spokes 5 , so that the coal blocks can all fall from the coal leakage opening 2 .

[0049] When in use, the crushed coal blocks are transported from the side of the coal bin 3 to the coal leakage platform 1, and the main coal sweeping rotary rod 6 is driven to rotate by the motor 7. When the main coal sweeping rotary rod 6 rotates, it can move the coal blocks stuck on the coal leakage nozzle 4 with a smaller spacing between the spacing spokes 5 through the auxiliary coal sweeping straight rod 8 until the coal blocks are moved to the spacing spokes 5 that can meet their falling requirements, thereby effectively avoiding a series of problems caused by coal block accumulation, thereby ensuring that the coal blocks fall normally to the bottom of the coal bin 3.

[0050] During the coal dropping process, in order to promote the rapid drop of coal blocks from the spaced spokes 5, the cam 16 is driven to rotate by the motor 15, and the protrusion 19 on the cam 16 continuously resists the upper support rod 17 to move upward. After each movement, it automatically falls under the action of its gravity, thereby realizing the reciprocating vibration of the coal nozzle 4 up and down, thereby promoting the rapid drop of coal blocks from the spaced spokes 5.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
