[0011] Wherein, a fixed seat is provided on the sliding seat, and one end of each of the first power member and the second power member away from the telescopic end is rotatably connected to the fixed seat.

[0012] Specifically, the cutting mechanism further includes a connecting seat. The cutting arm is connected to the connecting seat, and the connecting seat is connected to the slewing base.

[0015] Compared with the prior art, the crushing device provided by the present invention has the following advantages:

[0016] The crushing device provided by the present invention includes a pushing mechanism, a slewing mechanism, a lifting and lowering mechanism and a cutting mechanism.

[0037] As Figures 1 - 3 shown, the present invention provides a crushing device, including a pushing mechanism 7, a slewing mechanism, a lifting mechanism 10, and a cutting mechanism; one end of the pushing mechanism 7 is connected to the slewing mechanism, the cutting mechanism includes a cutting head 1, a cutting arm 2, and a power assembly, one end of the cutting arm 2 is connected to the slewing mechanism, and the other end is connected to the cutting head 1, and the power assembly drives the cutting head 1 to rotate; the lifting end of the lifting mechanism 10 is connected to the cutting arm 2, and the other end is connected to the slewing mechanism.

[0038] Compared with the prior art, the crushing device provided by the present invention has the following advantages:

[0039] After the mining operation is completed, it is necessary to convey the mined coal or stones out of the mine through the scraper conveyor and the transfer conveyor 11. After the installation of the scraper conveyor and the transfer conveyor 11, the space is further reduced. However, due to the special underground operation environment, it is difficult to further increase the space. Therefore, the existing crushers cannot enter the docking position between the scraper conveyor and the transfer conveyor 11, and thus cannot crush large pieces of materials.

[0040] The crushing device provided by the present invention can push the cutting mechanism to the docking position between the transfer conveyor 11 and the scraper conveyor through the pushing mechanism 7. The rotary mechanism and the lifting mechanism 10 can control the reciprocating movement of the cutting arm 2 in the horizontal and vertical directions. By driving the cutting head 1 to rotate through the power assembly, large materials can be crushed. Therefore, the crushing device provided by the present application realizes the crushing of large pieces of materials in a limited space, to a certain extent, avoiding the situation where large pieces of materials are stuck between the scraper conveyor and the transfer conveyor 11, and improving the operation efficiency.

[0041] When there are large pieces of materials stuck between the scraper conveyor and the transfer conveyor 11, the pushing mechanism 7 pushes the rotary mechanism to move in the direction close to the scraper conveyor, and makes the cutting head 1 contact the materials. Then, the power assembly drives the cutting head 1 to rotate relative to the cutting arm 2, so that large pieces of materials can be crushed. Moreover, through the cooperation of the lifting mechanism 10 and the rotary mechanism, the cutting head 1 can be rotated 360°, so as to improve the crushing effect on large pieces of materials to a certain extent.

[0042] After the crushing is completed, the pushing mechanism 7 pulls the rotary mechanism, so that the cutting head 1 is separated from between the scraper conveyor and the transfer conveyor 11, and a crushing operation of large pieces of materials is completed.

[0043] Preferably, the pushing mechanism 7 in the present application is a pushing oil cylinder, and an electric telescopic rod or a lead screw and other structures can also be used. The movement of the rotary mechanism is realized through the expansion and contraction of the pushing oil cylinder, so as to realize the cutting head 1 approaching or leaving the docking position between the scraper conveyor and the transfer conveyor 11.

[0044] Since the rotary mechanism in the present application needs to be able to move relative to the sealing plate of the transfer conveyor 11, a sliding mechanism is further included in the present application. The sliding mechanism includes a base 6 and a sliding seat 5. The base 6 is arranged on the sealing plate above the middle trough of the landing section of the transfer conveyor 11 along the extension direction of the pushing mechanism 7. The sliding seat 5 is slidably connected with the base 6. The rotary mechanism is arranged on the sliding seat 5. One end of the pushing mechanism 7 is connected with the sliding seat 5, and the sliding seat 5 is pushed to reciprocate on the base 6.

[0045] One end of the pushing mechanism 7 in the present application is connected with the sliding seat 5, and the other end is fixed to the base 6, so as to realize the reciprocating movement of the rotary mechanism relative to the sealing plate through the expansion and contraction of the pushing mechanism 7.

[0046] Such asFigures 1 - 3 As shown in the figure, the present application provides an implementation manner of the cutting head 1. Among them, the number of the cutting heads 1 is one, and the axis of the rotation axis of the cutting head 1 is collinear with the axis of the cutting arm 2. The output shaft of the motor drives the reducer to rotate, and the output shaft of the reducer is connected to the rotation axis of the cutting head 1, thereby driving the cutting head 1 to rotate and realizing the crushing of the material.

[0047] As Figure 4 shown, the present application also provides an implementation manner of the cutting head 1. Among them, the cutting head 1 includes a first cutting head 101 and a second cutting head 102, that is, two cutting heads 1 are included, and the two cutting heads 1 are respectively arranged on both sides of the cutting arm 2. The axis of the rotation axis of the first cutting head 101 and the axis of the rotation axis of the second cutting head 102 are both perpendicular to the axis of the cutting arm 2. The output shaft of the reducer is respectively connected to the rotation axis of the first cutting head 101 and the rotation axis of the second cutting head 102.

[0048] It should be supplemented and explained here that in the above two implementation manners, each cutting head 1 includes a cutting head main body 1011 and a plurality of cutting teeth 1012. The plurality of cutting teeth 1012 are distributed on the outer surface of the cutting head main body 1011, and as Figure 4 shown, in the second implementation manner, the cutting head main bodies 1011 of the two cutting heads 1 are both in a cylindrical structure.

[0049] When it is necessary to crush large pieces of material, the motor starts to drive the output shaft of the reducer to rotate, thereby driving the cutting head main body 1011 to rotate. The plurality of cutting teeth 1012 distributed on the cutting head main body 1011 impact the large pieces of material, realizing the crushing of the material.

[0050] It should be supplemented and explained here that as Figure 1 shown in combination with Figure 2 the figure, one end of the cylinder body of the push cylinder shown in the figure of the present application is connected to the sliding seat 5, and one end of the piston rod is connected to the base 6 is only one of the implementation manners. It is also possible to adopt that one end of the piston rod is connected to the base 6 and one end of the cylinder body is connected to the base 6.

[0051] It should be further supplemented and explained here that a guiding part can be provided on the base 6 of the present application, and the guiding part can be a guiding rail or a guiding groove. A guiding wheel is provided on the sliding seat 5 to cooperate with the guiding part, so that the sliding seat 5 can slide more smoothly on the base 6.

[0052] Specifically, as Figures 1 - 3 shown in the figure, the slewing mechanism includes a slewing base 4 and a slewing power member. The slewing base 4 is arranged on the sliding seat 5 and is rotatably connected to the sliding seat 5. The slewing power member drives the slewing base 4 to rotate relative to the sliding seat 5; one end of the cutting arm 2 away from the cutting head 1 is connected to the slewing base 4.

[0053] In this application, the rotary power component can directly drive the rotary seat 4 to rotate by cooperating an electric motor and a speed reducer, or can also drive the rotation of the rotary seat 4 relative to the sliding seat 5 by gear meshing. Preferably, however, the rotary power component in this application includes a first power member 8 and a second power member 9, and both the first power member 8 and the second power member 9 are hydraulic cylinders. By respectively arranging the telescopic ends of the first power member 8 and the second power member 9 on both sides of the rotary seat 4, when the rotary seat 4 needs to rotate, the telescopic end of the first power member 8 extends, and the telescopic end of the second power member 9 retracts, or the telescopic end of the first power member 8 retracts, and the telescopic end of the second power member 9 extends, so as to be able to realize the rotation of the rotary seat 4 relative to the sliding seat 5 in different directions.

[0054] Preferably, as Figures 1 - 3 shown, the cutting mechanism in this application further includes a connecting seat 3. The cutting arm 2 is connected to the connecting seat 3, and the connecting seat 3 is connected to the rotary seat 4.

[0055] It should be supplemented and explained here that one end of the lifting mechanism 10 in this application is rotatably connected to the cutting arm 2, and the other end is rotatably connected to the rotary seat 4. And when there is one lifting mechanism 10, the connection position of the telescopic end of the lifting mechanism 10 and the cutting arm 2 is located on the lower surface of the cutting arm 2, so as to be able to make the lifting and lowering of the cutting arm 2 more stable.

[0056] It should be supplemented and explained here that, as Figure 1 combined with Figure 2 shown, a fixed seat 501 is provided on the sliding seat 5. One ends of the first power member 8 and the second power member 9 far from the telescopic ends are both rotatably connected to the fixed seat 501. By providing the fixed seat 501, on the one hand, the connection between the first power member 8 and the second power member 9 can be made more stable, and on the other hand, the actions of the first power member 8 and the second power member 9 can be made not to affect each other.

[0057] Preferably, as Figures 1 - 3 shown, the lifting mechanism 10 in this application includes a first lifting member and a second lifting member. The first lifting member and the second lifting member are respectively arranged on both sides of the cutting arm 2, and one ends of the first lifting member and the second lifting member are both rotatably connected to the rotary seat 4, and the other ends are rotatably connected to the cutting arm 2.

[0058] Since the self-weights of the cutting head 1 and the cutting arm 2 are relatively large, therefore, by arranging the first lifting member and the second lifting member on both sides of the cutting arm 2, the lifting and lowering process of the cutting arm 2 can be made more stable.

[0059] It should be supplemented and explained here that preferably, both the first lifting member and the second lifting member in this application are hydraulic cylinders.

[0060] In addition, the present application further provides a transportation system, including a scraper conveyor, a transfer conveyor 11, and the above-mentioned crushing device; the scraper conveyor and the transfer conveyor 11 are butt-connected end to end, the crushing device is arranged on the sealing plate of the transfer conveyor 11, and the cutting mechanism of the crushing device can move to the butt-joint position of the scraper conveyor and the transfer conveyor 11.

[0061] The crushing device provided by the present application is actually arranged on the sealing plate above the middle trough of the landing section of the transfer conveyor 11. On the one hand, it can not affect the normal material transportation of the transfer conveyor 11. On the other hand, when large pieces of materials are stuck between the scraper conveyor and the transfer conveyor 11, the cutting mechanism can quickly crush the large pieces of materials, and after crushing, they can be transported out through the conveyor belt of the transfer conveyor 11, thereby improving the operation efficiency to a certain extent.

[0062] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
