Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a grading and screening device for crushers. Background Art

[0002] Crusher is commonly used to crush rocks produced during mining. It often uses methods such as squeezing, splitting, bending, impacting, and rolling to break large rocks into pieces. Commonly used crushers include jaw, cone, hammer, and roller crushers.

[0003] However, the existing crushers lack grading and screening measures when in use. Workers often directly pour the ore into the crusher in piles. The smaller particles of ore do not need to be crushed, but will occupy the internal space of the crusher, thereby affecting the overall crushing efficiency. Oversized ore often causes the crusher to overload and shorten its service life. Therefore, a grading and screening device for a crusher is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a grading and screening device for a crusher includes a first support rod 1 and a mounting frame 2, a reinforcing rod 14 is fixedly connected between the two first support rods 1, a connecting rod 13 is fixedly connected to the side wall of the first support rod 1, the end of the connecting rod 13 is fixedly connected to the second support rod 8, another reinforcing rod 14 is fixedly connected between the two second support rods 8, one end of the mounting frame 2 is rotatably connected between the two first support rods 1, and the other end of the mounting frame 2 is connected to the two second support rods 8 through an adjusting assembly, a screening frame 3 is arranged above the mounting frame 2, a vibration pump 5 is fixedly connected to the side wall of the screening frame 3, and the bottom of the screening frame 3 is connected to the mounting frame 2 through a spring 12, the number of the springs 12 is four, and the four springs 12 are respectively distributed at the four corners of the bottom of the screening frame 3, a crusher body 7 is arranged below the front end of the screening frame 3, a screening plate 6 is arranged above the opening of the crusher body 7, and the screening plate 6 is fixedly connected to the first support rod 1.

[0021] Among them, the adjustment component includes a fixing hole 9, a matching hole 11 and a fixing rod 10. The matching hole 11 is opened on the upper side of the side wall of the second support rod 8. The fixing rod 10 is slidably inserted into the matching hole 11. Three fixing holes 9 are opened on the side wall of the mounting frame 2.

[0022] The fixing rod 10 is inserted into the matching hole 11 and the fixing hole 9 in sequence, so as to connect the second support rod 8 with the mounting frame 2 . The inclination angle of the mounting frame 2 can be adjusted by inserting the fixing rod 10 into different fixing holes 9 .

[0023] Among them, the distances between the three fixing holes 9 and the rotation center of the mounting frame 2 are equal, and the three fixing holes 9 are evenly spaced. The distance between the rotation center of the mounting frame 2 and the fixing holes 9 is equal to the distance between the rotation center of the mounting frame 2 and the matching hole 11.

[0024] Such an arrangement can ensure that the three fixing holes 9 can be aligned with the matching holes 11 after the mounting frame 2 is rotated.

[0025] The diameter of the fixing hole 9 is smaller than the diameter of the fixing rod 10 , and the fixing rod 10 has elastic properties.

[0026] When the fixing rod 10 is inserted into the fixing hole 9 in this way, the fixing rod 10 will be deformed, and the expansion force of the fixing rod 10 to restore the deformation will clamp the fixing rod 10 in the fixing hole 9, thereby fixing the mounting frame 2 and the second support rod 8 together.

[0027] The screening plate 6 is arranged to be inclined relative to the horizontal plane, and the area of ​​the screening plate 6 is larger than the area of ​​the crusher body 7 .

[0028] With such arrangement, when cleaning the large ores intercepted on the screening plate 6 , the staff can push the large ores down along the inclined surface, and the area of ​​the screening plate 6 is larger than the area of ​​the crusher body 7 to ensure that the falling large ores will not hit the crusher body 7 .

[0029] Wherein, guide plates 4 are fixedly connected to both sides of the upper end of the screening frame 3 .

[0030] The material guide plate 4 can prevent the ore falling on the screening frame 3 from scattering to both sides.

[0031] The utility model provides a grading and screening device for a crusher, and the specific working principle is as follows:

[0032] When in use, pour the ore onto the screening frame 3, the inclination angle of the mounting frame 2 can be controlled by adjusting the assembly, and then the vibration pump 5 is started, and the screening frame 3 is connected to the mounting frame 2 by four springs 12. When the vibration pump 5 is started, the screening frame 3 will vibrate, so that the small particles of ore in the ore will be screened out through the filter holes on the screening frame 3, and the screening frame 3 is inclined. The ore remaining on the screening frame 3 will slide along the inclined surface to the screening plate 6. The different inclination angles of the mounting frame 2 can control the sliding speed of the ore. A plurality of larger filter holes are provided on the screening plate 6, which can intercept oversized ores to prevent the ore from entering the crusher body 7 and causing the crusher body 7 to overload. Ores of moderate size will fall into the crusher body 7 and be crushed. The large ores intercepted on the screening plate 6 are relatively small in number and can be manually cleared by the staff.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
