Stone crushers primarily include jaw crushers, impact crushers, cone crushers, and hammer crushers.

[0003] Among them, the common impact crusher mainly consists of a crusher box, with a feed port and a discharge port at the top of the box. Stones enter the box through the feed port and come into contact with the rotating rotor inside the box. The stones are affected by the high-speed rotation of the rotor, gaining a high speed and colliding with the impact plate inside the box and breaking. The feed port is mostly a conical cover structure. When a large amount of stone is fed in at one time, the stone will often block the feed port. At this time, staff need to clear the blockage. During the clearing process, due to the continuous rotation of the rotor, some stones in the box will burst out from the feed port, posing a safety hazard to staff. Utility Model Content

[0024] A feeding bin 9 is located above the crushing tank 3, with an accordion-style jacket 10 installed between the feeding bin 9 and the crushing tank 3. The feeding bin 9 is connected to the crushing tank 3 through the accordion-style jacket 10. Stones to be crushed are fed into the base 1 through the feeding bin 9 above the crushing tank 3. A drive device controls the rotation of the crushing rollers in the crushing tank 3. As the crushing rollers rotate, they cooperate with the crushing plates inside the crushing tank 3 to crush the stones. The crushing tank 3 here is a conventional technical solution and will not be described in detail here.

[0025] A fixed frame 12 is provided at the top of the base 1, which is fixedly connected to the base 1. A reciprocating assembly is mounted on the fixed frame 12 to push the feeding bin 9 to swing left and right. The feeding bin 9 is connected to the crushing tank 3 via an accordion-style sheath 10. The accordion-style sheath 10 supports the feeding bin 9 to swing above the crushing tank 3. The reciprocating assembly is mounted on the fixed frame 12. By pushing the feeding bin 9 to swing left and right, any gravel stuck in the feeding bin 9 can be shaken out, ensuring smooth feeding of the crushing tank 3.

[0026] About Smash the Jar 3:

[0027] The axis of the crushing tank 3 coincides with the axis of the crushing roller. The top of the crushing roller is rotatably connected to the top of the crushing tank 3. A discharge port is provided below the rotating roller and is located at the lower end of the crushing tank 3. An observation window panel 11 is provided on the outside of the crushing tank 3 and is rotatably connected to the crushing tank 3. A bolt connector is provided at the connection between the observation window panel 11 and the crushing tank 3 for locking the observation window panel 11. After releasing the bolt connector from securing the observation window panel 11, the observation window panel 11 can be opened to perform maintenance on the crushing roller within the crushing tank 3.

[0028] About the installation frame:

[0029] The mounting frame includes a stand 5 and a rectangular frame 4. The rectangular frame 4 is fixedly connected to the upper end of the stand 5, which is in turn fixedly connected to the upper end of the base 1. The end of the rectangular frame 4, away from the stand 5, is fixedly connected to the upper end of the crushing tank 3. A plurality of triangular plates 6 are fixedly connected between the stand 5 and the crushing tank 3, and between the stand 5 and the rectangular frame 4. The stand 5 is fixedly connected to the upper end of the base 1 to support the rectangular frame 4. The triangular plates 6 are provided at the connection between the base 1 and the stand 5, and at the connection between the stand 5 and the rectangular frame 4, to enhance the structural strength of the connection between the base 1 and the stand 5, and at the connection between the stand 5 and the rectangular frame 4, thereby improving the stability of the entire mounting frame.

[0030] For the specific structure of the drive device, please refer to the following description.

[0031] The drive unit includes a first motor 7 and two pulleys 8. The mounting end of the first motor 7 is fixedly connected to the upper end of the rectangular frame 4. The output end of the first motor 7 is fixedly connected to one of the pulleys 8. The other pulley 8 is fixedly connected to the top of the crushing roller via a connecting shaft. The two pulleys 8 are movably connected by a transmission belt. The drive unit uses a belt drive to control the rotation of the crushing roller. The advantage of a belt drive is that the belt is elastic and can effectively reduce impact and vibration loads. It can also absorb and buffer vibrations during the transmission process to a certain extent, protecting transmission components from damage. When the drive unit is overloaded, the belt will slip on the pulleys, preventing damage to transmission components due to excessive load, thus ensuring the safety and reliability of the drive unit.

[0032] For the specific structure of the reciprocating assembly, please refer to the following description.

[0033] The reciprocating assembly includes a movable plate 14 and two limit rods 13. The limit rod 13 is fixedly connected to the side of the feeding bin 9 facing the fixed frame 12. The limit rod 13 passes through the fixed frame 12 at one end away from the feeding bin 9 and is fixedly connected to the movable plate 14. The limit rod 13 is slidingly connected to the fixed frame 12. A spring 17 is provided on the outside of the limit rod 13. The two ends of the spring 17 are respectively fixedly connected to the fixed frame 12 and the feeding bin 9. An eccentric wheel mechanism is provided between the fixed frame 12 and the movable plate 14 for pushing the movable plate 14 to swing left and right.

[0034] The eccentric wheel mechanism pushes the movable plate 14 to swing left and right. The movable plate 14 is fixed to the feeding bin 9 through the limit rod 13. When the movable plate 14 swings left and right, the feeding bin 9 will also swing. The limit rod 13 can slide along the inner wall of the fixed frame 12 to guide the limit rod 13.

[0035] It is worth further explaining that the eccentric mechanism includes a second motor 16, an eccentric 18 and a matching block 15. The second motor 16 is fixedly connected to the upper end of the fixed frame 12, and the output end of the second motor 16 is fixedly connected to the eccentric 18. The matching block 15 is fixedly connected to the side of the movable plate 14 facing the fixed frame 12, and the matching block 15 is movably matched with the outer edge of the eccentric 18. The axis of the eccentric 18 does not coincide with the axis of the second motor 16. Under the pull of the spring 17, the matching block 15 on the movable plate 14 always remains in close contact with the eccentric 18. When the second motor 16 drives the eccentric 18 to rotate, the outer edge of the eccentric 18 will push the matching block 15. Due to the existence of the eccentricity, the outer edge of the eccentric 18 will push the matching block 15 to perform reciprocating horizontal motion.

[0036] Furthermore, a support frame 2 is located at the lower end of base 1. This frame comprises multiple columns, which are fixedly connected to base 1. Rubber pads are located at the lower ends of the columns, and reinforcing ribs are located at the connection between the upper ends of the columns and base 1. The reinforcing ribs are fixed to base 1 and the columns, primarily serving to strengthen the structural strength of the connection between base 1 and the columns, thereby improving the stability of the entire device. Rubber pads are fixed to the lower ends of the columns to provide anti-slip properties.

[0037] How this application works:

[0038] The stones to be crushed are fed into the base 1 through the feeding bin 9 above the crushing tank 3. The driving device controls the rotation of the crushing rollers in the crushing tank 3. The crushing rollers rotate and cooperate with the crushing plates inside the crushing tank 3 to crush the stones.

[0039] The feeding bin 9 is connected to the crushing tank 3 through an accordion-type jacket 10. The accordion-type jacket 10 supports the feeding bin 9 to swing above the crushing tank 3. The reciprocating assembly is installed on the fixed frame 12, pushing the two feeding bins 9 to shake left and right, shaking out the gravel blocked in the feeding bin 9, ensuring smooth feeding of the crushing tank 3. The mechanical shaking and dredging method saves manpower and is highly safe.
