Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a coal mine crusher used in coal mining. Background Art

[0002] Crusher plays a key role in coal mining. It can break the original coal blocks into the required particle size to facilitate the subsequent coal selection, transportation and utilization.

[0003] The prior art discloses a coal mine crusher with easy impurity removal, with an invention patent application number of CN201611030031.7. The principle is that the crushed coal particles in the crushing chamber enter the filter chamber and fall onto the fixed plates equidistantly arranged on the conveyor belt. The vibration motor vibrates the conveyor belt and the fixed plates through the vibration plate, so that the coal particles accumulated on the fixed plates are evenly distributed on the conveyor belt, and the coal particles that do not meet the standard size and the large impurities that cannot be crushed remain on the fixed plates. The coal particles that do not meet the standard size and the large impurities that cannot be crushed that remain on the fixed plates reach the conveyor plate and are delivered to the conveyor plate by the thrust of the conveyor belt and slide down. The coal particles that meet the standards reach the corner of the conveyor belt, fall by their own gravity, and are discharged from the discharge port, thereby solving the problem that the traditional crusher that can remove impurities needs to use a screen plate to remove impurities, thereby greatly improving the work efficiency.

[0004] However, when it is in use, the larger coal blocks are only supported by two adjacent fixed plates, which are then scooped up by the conveyor plate and discharged from the impurity discharge port. The coal blocks have different shapes after being crushed. When the coal blocks fall on the two adjacent fixed plates, they are easily stuck between the two fixed plates, which makes it impossible for the coal blocks to be scooped up by the conveyor plate and discharged from the impurity discharge port, resulting in reduced coal block crushing efficiency.

In addition, in the description of this utility, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0027] like Figures 1 to 5As shown; a coal mine crusher used in coal mining, including a body 1 and a feed port 2 and a discharge port 3 respectively arranged at the top and the bottom, the right outer wall of the body 1 is provided with a debris discharge port 4, the inner wall of the body 1 is rotatably connected to a pair of crushing rollers 5 that rotate synchronously through gears, the outer wall of the body 1 is fixedly connected to a motor 6, the main shaft of the motor 6 is fixedly connected to the rotating shaft of the crushing roller 5, a plurality of equidistantly arranged partition plates 7 are arranged inside the body 1, the inner wall of the body 1 is rotatably connected to a first rotating rod 8 that rotates synchronously with the crushing roller 5 through a belt, and the first rotating rod 8 The outer wall is evenly and fixedly connected with a plurality of equidistantly arranged eccentric wheels 9, the inner wall of the body 1 is fixedly connected with a limit plate 10, the limit plate 10 is penetrated by a guide rod 11, and the outer wall of the guide rod 11 is slidably connected with the inner wall of the limit plate 10 penetrated, the guide rod 11 is sleeved with a pressure spring 12, one end of the pressure spring 12 is fixedly connected with the outer wall of the guide rod 11, the other end of the pressure spring 12 abuts against the outer wall of the limit plate 10, and the outer wall of the eccentric wheel 9 abuts against one end of the guide rod 11, and the inner wall of the impurity discharge port 4 is fixedly connected with an impurity discharge plate 13;

[0028] When in use, the coal blocks to be crushed are put into the machine body 1 from the feed port 2, and the motor 6 is started to run. The motor 6 drives the crushing roller 5 to rotate, and the crushing roller 5 rotates to crush the coal blocks. The crushed coal blocks will fall downward, pass through the dividing plate and fall to the bottom of the machine body 1, and then be discharged through the discharge port 3, while the larger unqualified coal blocks will fall on two adjacent dividing plates 7. The rotation of the crushing roller 5 will synchronously drive the first rotating rod 8 to rotate through the belt, and the rotation of the first rotating rod 8 will drive the eccentric wheel 9 fixed on its outer wall to rotate, and the rotation of the eccentric wheel 9 Its outer wall will push the guide rod 11 in a cycle, and the guide rod 11 will reset under the elastic force of the pressure spring 12, so that the guide rod 11 will push the unqualified coal blocks that fall on the partition plate 7, so that the unqualified coal blocks fall on the impurity discharge plate 13. Since the unqualified coal blocks are pushed by the guide rod 11, the coal blocks will not be stuck between the two adjacent partition plates 7. The unqualified coal blocks that fall on the impurity discharge plate 13 will enter the impurity discharge port 4 and be discharged from the machine body 1, thereby increasing the efficiency of crushing the coal blocks.

[0029] like Figure 3 and Figure 5 As shown; the inner wall of the body 1 is rotatably connected to a second rotating rod 14 that rotates synchronously with the first rotating rod 8 through a belt, the inner wall of the body 1 is rotatably connected to a fixedly connected limit rod 15, and the limit rod 15 penetrates the partition plate 7 and is slidably connected, one end of the partition plate 7 is rotatably connected to a rotating disk 16, and the rotating disk 16 is penetrated by the second rotating rod 14 and is slidably connected, and a conveyor belt 17 is sleeved on the partition plate 7 and the rotating disk 16;

[0030] When in use, the rotation of the first rotating rod 8 will synchronously drive the second rotating rod 14 to rotate through the belt, and the rotation of the second rotating rod 14 will drive the turntable 16 to rotate. The rotation of the turntable 16 will drive the conveyor belt 17 to circulate on the turntable 16 and the partition plate 7. The rotation of the conveyor belt 17 transports the unqualified coal blocks that have fallen on the partition plate and moves them to the debris discharge plate 13, thereby increasing the transportation efficiency of the unqualified coal blocks that have fallen on the partition plate 7 but are not stuck on the two adjacent partition plates 7, thereby increasing the overall crushing efficiency of the coal blocks.

[0031] like Figure 3 and Figure 6 As shown; the inner wall of the body 1 is rotatably connected to an adjusting rod 18, and the outer wall of the adjusting rod 18 is evenly fixedly connected to a plurality of adjusting plates 19, and a tension spring 20 is provided between two adjacent partition plates 7, and the two sides of the adjusting plate 19 are symmetrically inclined;

[0032] When in use, the position of the adjusting plate 19 can be controlled by rotating the adjusting rod 18, and the two adjacent partition plates 7 are fitted with the adjusting plate 19 through the tension of the tension spring 20, and the two sides of the adjusting plate 19 are symmetrically inclined. Therefore, when the adjusting plate 19 moves, the partition plate 7 will move and fit against the outer wall of the adjusting plate 19 under the tension of the tension spring 20, thereby adjusting the distance between the partition plates 7, so that the partition plates 7 can intercept unqualified coal blocks of different sizes according to needs.

[0033] like Figure 3 As shown; the partition plate 7 is arranged to be inclined toward the debris removal plate 13;

[0034] When in use, the partition plate 7 is designed to be inclined toward the impurity removal plate 13, so that unqualified coal blocks dropped on the partition plate 7 can roll toward the impurity removal plate 13 under their own gravity, thereby increasing the screening efficiency of unqualified coal blocks.

[0035] like Figure 4 As shown; the other end of the guide rod 11 is fixedly connected to a shovel block 21, and the other end of the shovel block 21 is inclined;

[0036] When in use, by setting a shovel block 21, the shovel block 21 can move back and forth with the guide rod 11, and the end of the shovel block 21 away from the guide rod 11 is inclined, so that when the shovel block 21 moves, it can have an upward shoveling effect on the unqualified coal blocks stuck between two adjacent partition plates 7, so that the stuck unqualified coal blocks are pushed to the upper side of the partition plate 7 and then discharged from the machine body 1, thereby increasing the crushing effect of the coal blocks.

[0037] like Figure 3As shown; the end of the guide rod 11 that abuts against the outer wall of the eccentric wheel 9 is arranged in an arc shape;

[0038] When in use, the end of the guide rod 11 that abuts against the eccentric wheel 9 is designed to be arc-shaped, so that the friction between the eccentric wheel and the guide rod 11 is reduced when the eccentric wheel pushes the guide rod 11, thereby reducing the probability of mutual wear between the two.

[0039] like Figure 3 and Figure 5 As shown; the conveyor belt 17 is made of polyurethane rubber;

[0040] When in use, the polyurethane rubber has very good wear resistance, oil resistance and abrasion resistance, and also has good elasticity and cushioning properties, thereby increasing the service life of the conveyor belt 17, and having a cushioning effect on the coal blocks, reducing the probability of the partition plate 7 being damaged by impact.

[0041] like Figure 3 As shown; one end of the impurity removal plate 13 away from the impurity removal port 4 is in contact with the outer surface of the conveyor belt 17;

[0042] When in use, the debris removal plate 13 can act as a shovel for the unqualified coal blocks on the conveyor belt 17 , thereby making it easier for the unqualified coal blocks to fall onto the debris removal plate 13 .

[0043] How this utility works:

[0044] Refer to the instruction manual Figure 1-5 As shown, the coal blocks to be crushed are put into the machine body 1 from the feed port 2, and the motor 6 is started to run. The motor 6 drives the crushing roller 5 to rotate, and the crushing roller 5 rotates to crush the coal blocks. The crushed coal blocks will fall downward, pass through the dividing plate and fall to the bottom of the machine body 1, and then be discharged through the discharge port 3, while the larger unqualified coal blocks will fall on two adjacent dividing plates 7. The rotation of the crushing roller 5 will synchronously drive the first rotating rod 8 to rotate through the belt, and the rotation of the first rotating rod 8 will drive the eccentric wheel 9 fixed on its outer wall to rotate, and the eccentric wheel 9 rotates its The outer wall will push the guide rod 11 in a cycle, and the guide rod 11 will reset under the elastic force of the pressure spring 12, so that the guide rod 11 will push the unqualified coal blocks that fall on the partition plate 7, so that the unqualified coal blocks fall on the impurity discharge plate 13. Since the unqualified coal blocks are pushed by the guide rod 11, the coal blocks will not be stuck between the two adjacent partition plates 7. The unqualified coal blocks that fall on the impurity discharge plate 13 will enter the impurity discharge port 4 and be discharged from the machine body 1, thereby increasing the efficiency of crushing the coal blocks.

[0045] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
