Description

Technical Field

[0001] The utility model relates to the technical field of raw coal transportation, in particular to a device for regulating the raw coal transportation amount. Background Art

[0002] With the regular production of Plant 3, in order to further optimize resource allocation and improve overall production efficiency, considering that Plant 3 has a more advanced coal supply system, the company decided to stop using the coal yard and corresponding coal unloading equipment of Plant B. The coal supply system of Plant 3 will take on the task of supplying raw coal to Plant B to ensure the normal production and operation of Plant B, while avoiding repeated investment and waste of resources. In order to realize the function of Plant 3 supplying coal to Plant B, the equipment department has carried out a series of transformations on the coal transportation system. First, the C3A and C3B coal conveying belts of Plant 3 were frequency-converted to supply small amounts of coal to Plant B. After the transformation, the C3A and C3B belts were tested and operated normally, and the frequency conversion transformation was successful. However, when supplying coal to Plant B in the test, the higher coal layers collapsed to both sides, and the spilled raw coal might be re-entered by the belt, causing the belt to slip, trip, and even cause serious accidents such as fire. Therefore, corresponding transformation must be carried out. In order to solve this problem, it is urgent to develop a device that can flexibly adjust the raw coal delivery volume. Utility Model Content

[0003] The utility model aims to provide a device for flexibly adjusting the raw coal conveying amount, which adjusts the raw coal conveying amount by moving the plug plate, thereby avoiding the problem that the high-stacked coal layer collapses to both sides and the spilled raw coal may be re-entered by the belt.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A device for flexibly adjusting the amount of raw coal conveyed, comprising a feed bin (1), a guide bin (2), a conveyor belt (3), an external support (4), and a motor (31), characterized in that it also comprises a plug plate (21), a plug plate hand wheel (22), a threaded shaft (23), a leak-proof plate (32), a limit plate (33), and a limit hand wheel (34);

[0006] The conveyor belt (3) is fixedly mounted on the lower inner part of the outer bracket (4) and fits with the inner side of the supporting leg of the outer bracket (4). A pair of leak-proof plates (32) are fixedly mounted on both sides of the upper end of the conveyor belt (3) in parallel. A feed bin (1) is mounted on the inlet end of the conveyor belt (3), and a guide bin (2) is mounted on the outlet end of the conveyor belt (3). An opening is arranged on the upper end of the guide bin (2), and the plug plate (21) is slidably connected to the corresponding opening. A threaded shaft (23) is fixedly mounted on the top end of the plug plate (21), and the threaded shaft (23) passes through a threaded hole in the center of the horizontal bracket at the top end of the outer bracket (4) and is threadedly connected to the plug plate hand wheel (22).

[0007] The insert plate hand wheel (22) is threadedly mounted on a pair of leak-proof plates (32) at the feed end of the material guide bin (2); one side of the limit plate (33) is rotatably mounted on the inner side of the insert plate hand wheel (22), and the other side is tightly fitted on the threaded shaft end of the limit plate hand wheel (34);

[0008] The head of the conveyor belt (3) is equipped with a motor (31) for providing power.

[0009] The lower part of the insert plate (21) is in a half-moon shape, and has the same thickness as the opening of the material guide bin (2).

[0010] The material guide bin (2) is in an inverted U shape and is provided with a slot which is slidably matched with the leak-proof plate (32).

[0011] The supporting legs of the outer bracket (4) are of the same length, and the outer bracket (4) is a steel structure connected by bolts.

[0012] The conveyor belt (3) can be connected to a conveyor belt of the same model by adding a connecting slideway, thereby extending the conveying distance.

[0013] First, assemble the outer bracket (4) by bolting, ensuring that the lengths of the supporting legs are the same to provide stable support. Fix the conveyor belt (3) on the lower inner side of the outer bracket (4) so ​​that it fits tightly against the inner side of the supporting legs of the outer bracket (4). Install a motor (31) at the head of the conveyor belt (3) to provide power for the operation of the conveyor belt (3). Then, install the guide bin (2) above the outlet end of the conveyor belt (3), and the slot at the bottom of the guide bin (2) slides with the leak-proof plates (32) fixed parallel to both sides of the conveyor belt (3). Install the plug plate (21) at the upper opening of the guide bin (2). The lower part of the plug plate (21) is half-moon-shaped and has the same thickness as the opening to ensure tight sliding.

Then, one side of the limit plate (33) is installed on the inner side of the insert plate hand wheel (22) in a rotating manner, and the other side is tightly fitted to the threaded shaft end of the limit hand wheel (34). By rotating and adjusting the limit hand wheel (34), the angle of the limit plate (33) is changed, and the flow direction and conveying amount of the raw coal are further fine-tuned. If it is necessary to extend the conveying distance, the same type of conveyor belt can be used, and a connecting slide can be added to connect them to meet the actual conveying needs. In actual operation, if it is necessary to reduce the raw coal conveying amount, the insert plate hand wheel (22) can be rotated clockwise to move the insert plate (21) into the opening, reduce the opening area, and thus reduce the amount of raw coal falling. If it is necessary to change the distribution of raw coal on the conveyor belt (3), the angle of the limit plate (33) can be changed by adjusting the limit hand wheel (34). When the conveying distance is long, more conveyor belts can be connected according to specifications to ensure that the raw coal can be smoothly transported to the designated location.
