Description

Technical Field

[0001] The utility model relates to the technical field of shearer drum gear cutting, in particular to a shearer drum gear cutting angle corrector. Background Art

[0002] The shearer drum cutting teeth are an important part of the shearer, which directly affects the coal mining efficiency and quality of the shearer. The shearer drum cutting teeth are usually composed of multiple teeth, and the shape and arrangement of these teeth will affect the coal mining effect of the shearer.

[0003] The main function of the shearer drum cutting teeth is to cut the coal seam into small pieces so that the shearer can transport them away. However, the service life of the shearer drum cutting teeth is usually short and needs to be replaced regularly. Most existing replacement methods have the following shortcomings:

[0004] Since the cutting teeth of the shearer cutting drum are frequently used on the working surface for a long time and the length of the cutting teeth is inconsistent, the cutting teeth are unevenly stressed during use, resulting in inconsistent wear of the cutting teeth. As a result, each replacement of the drum takes a long time, affecting normal production.

[0005] In response to the above problems, this utility model document proposes a coal mining machine drum cutting tooth angle corrector. Utility Model Content

[0006] The utility model provides a coal mining machine drum cutting tooth angle corrector, which solves the shortcomings in the prior art that the coal mining machine cutting drum cutting teeth are used frequently on the working surface for a long time, and the cutting teeth are inconsistent in length. During use, the cutting teeth are subjected to uneven force, resulting in inconsistent wear of the cutting teeth, resulting in a long time required for each replacement of the drum, which affects normal production.

[0007] The utility model provides the following technical solutions:

[0008] Coal mining machine drum cutting tooth angle corrector, including:

[0009] A mounting seat, wherein a rotation groove is formed on the top of the mounting seat, and a dividing plate is rotatably connected to the interior of the rotation groove;

[0010] A support rod is fixedly provided on the top side of the dividing plate, a through hole is provided inside the support rod, a cross rod slides through the through hole, and a threaded hole connected to the through hole is provided on the top end of the support rod.

[0011] In a possible design, the internal thread of the threaded hole is connected to a locking screw for locking and fixing the cross bar, and a locking rotating rod is fixedly provided on the top end of the locking screw.

[0012] In a possible design, a scale is provided on the outside of the crossbar, and a sliding hole is provided inside the scale and is slidably connected to the outer wall of the crossbar.

[0013] In a possible design, a threaded plate is fixedly provided on one side of the ruler, and the internal threads of the threaded plate are connected to a locking screw button that is compatible with the cross bar, and the locking screw button is used to lock and fix the ruler.

[0014] In a possible design, a limit block is fixedly provided at one end of the crossbar to limit the sliding of the ruler.

[0015] In a possible design, fixing holes are symmetrically arranged in pairs on the top of the mounting base.

[0016] In the present application, when in use, first, the mounting base is firmly mounted on the coal mining machine drum or the corresponding fixed position through the fixing holes symmetrically opened in pairs on the top thereof. The fixing holes allow the corrector to be firmly fixed in the desired position using bolts or other fasteners. After the installation is completed, the angle of the cutting teeth is adjusted by rotating the connected dividing plate in the rotating groove. The design of the dividing plate allows the operator to rotate it to a suitable angle position according to specific needs to achieve precise alignment of the cutting teeth. The support rod is fixed to the top side of the dividing plate, and the through hole opened inside it allows the cross bar to slide freely. By adjusting the position of the cross bar in the through hole, the specific position or angle of the cutting teeth can be further fine-tuned. The locking screw in the threaded hole is tightened by rotating the locking rod, thereby fixing the cross bar in the desired position to prevent it from being displaced during operation;

[0017] The ruler set on the outside of the crossbar provides an intuitive visual reference to help the operator accurately judge and adjust the position of the cutting teeth. The ruler slides on the crossbar through the sliding hole to achieve accurate position marking. When the ruler is adjusted to the required position, the locking screw connected to the internal thread of the threaded plate is used to lock the ruler on the crossbar to ensure that the ruler will not move due to external force, maintaining the accuracy and stability of the correction, so that it can be used to correct the cutting tooth angle of the coal mining machine drum, so that the cutting tooth angle is consistent and the length is consistent, and the cutting tooth is evenly stressed during operation, which enhances the use effect. The limit block at one end of the crossbar ensures that the ruler will not exceed the predetermined safety range during the sliding process, preventing damage or adjustment errors caused by excessive movement, and improving the applicability effect.

[0018] In the present invention, the shearer drum tooth cutting angle corrector, through the arrangement of structures such as the indexing plate, support rods, through holes, cross bars, threaded holes and locking screws, allows the operator to rotate to a suitable angle position according to specific needs to achieve precise alignment of the cutting teeth. The specific position or angle of the cutting teeth can also be further fine-tuned, while fixing the cross bar in the required position to prevent it from displacement during operation.

[0019] In the utility model, the shearer drum tooth cutting angle corrector can help the operator accurately judge and adjust the position of the tooth cutting by setting the scale, threaded plate and locking screw structure to achieve accurate position marking. At the same time, the scale can be locked on the crossbar to ensure that the scale will not move due to external force, thereby maintaining the accuracy and stability of the correction.

[0020] The utility model can be used to correct the tooth cutting angle of the coal mining machine drum, so that the tooth cutting angle is consistent and the length is consistent, which is beneficial to uniform force on the tooth cutting during operation, avoiding inconsistent wear of the tooth cutting, resulting in a long time required for each drum replacement, and enhancing the use effect.
