Description

Technical Field

[0001] The utility model relates to the technical field of crushing equipment, in particular to a mineral material four-tooth roller crusher. Background Art

[0002] The four-tooth roller crusher uses four high-strength, wear-resistant rollers that rotate relative to each other to generate high extrusion and shear forces to crush materials. After entering the gap between the upper two tooth rollers, the materials are squeezed and sheared by the relative rotation of the two tooth rollers for the first time. After shearing twice, they enter the relatively rotating lower two rollers, where they are squeezed, sheared, and ground into the required particle size before being discharged from the discharge port.

[0003] At present, in the process of crushing ore materials, four-tooth roller crusher is usually used to crush the ore materials. The four-tooth roller crusher has the advantage of directly performing secondary crushing on the materials and improving the crushing efficiency. However, in the process of crushing ore materials, there are still the following defects:

[0004] During the secondary crushing process of the ore by the four-tooth roller crusher, the ore is easily over-crushed. However, most of the current four-tooth roller crushers lack a screening mechanism to screen the crushed material. As a result, when the crushed ore is discharged through the discharge port, the over-crushed ore is mixed with the ore of the required size, thereby reducing the quality of the ore after crushing.

[0005] Therefore, the present application proposes a mineral material four-tooth roller crusher. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention. Example 1

[0030] In order to solve the technical problems in the background technology, the following four-tooth roller crusher for mineral materials is provided:

[0031] Combine Figure 1-Figure 5 As shown, the utility model provides a mineral material four-tooth roller crusher, including a crusher body 1, characterized in that: the crusher body 1 includes a casing 11, the top of the casing 11 is provided with a feed port 12 connected to the interior thereof, and the bottom is provided with a discharge port 13 connected to the interior thereof; two mutually meshing crushing rollers 14 are rotatably installed in the casing 11, and the two crushing rollers 14 are located on the same horizontal plane, and two meshing crushing rollers 2 15 are rotatably installed in the casing 11 and below the two crushing rollers 14. It is worth noting that the crushing tooth density on the crushing roller 2 15 is greater than the crushing tooth density on the crushing roller 14. When in use, the crushed material to be crushed is The crushed ore is fed into the casing 11 through the feed port 12 to control the operation of the crusher body 1. During this period, the two crushing rollers 14 rotate to perform primary crushing on the ore to be crushed, and then fall between the two crushing rollers 15. The two crushing rollers 15 rotate to perform secondary crushing on the ore crushed by the two crushing rollers 14, and then discharge it through the discharge port 13 to improve the crushing effect; a support plate 2 is symmetrically fixed to the bottom of the casing 11 and located on the outside of the discharge port 13, and a bottom plate 21 is fixed to the bottom of the two support plates 2. A screening mechanism 3 is installed on the bottom plate 21 and below the discharge port 13, which is used to screen the ore crushed by the crusher body 1.

[0032] By setting up the screening mechanism 3, when the ore is crushed by the crusher body 1, the crushed ore is discharged through the discharge port 13 and falls onto the screening mechanism 3. The crushed ore is screened by the screening mechanism 3, which effectively avoids the situation where the over-crushed ore is mixed with the ore of the required size after the ore is crushed, thereby improving the quality of the ore after crushing. Example 2

[0033] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following content:

[0034] In this embodiment, the screening mechanism 3 includes: a mounting plate 31, a vertical plate 32 is symmetrically fixedly installed on the top of the bottom plate 21 and below the discharge port 13, and hinge shafts 311 are symmetrically fixed on both sides of the mounting plate 31. The mounting plate 31 is hinged to the opposite sides of the two vertical plates 32 through two hinge shafts 311. A through hole 312 is provided on the top of the mounting plate 31, and a screening plate 33 for blocking the through hole 312 is installed on the mounting plate 31. A plurality of screening holes are provided on the screening plate 33, all of which are connected to the through hole 312. The top of the bottom plate 21 and the outer surface of the casing 11 are connected to the vertical plate 32. A driving member 34 acting on the mounting plate 31 is installed on the side, which is used to make the mounting plate 31 reciprocate between the opposite sides of the two vertical plates 32 around the two hinge shafts 311. When in use, the mineral material crushed by the crusher body 1 falls downward onto the screening plate 33 through the discharge port 13. During this period, the mounting plate 31 is made to reciprocate between the opposite sides of the two vertical plates 32 around the two hinge shafts 311 through the driving member 34, thereby driving the mineral material falling on the screening plate 33 to shake, and the over-crushed mineral material falls downward onto the bottom plate 21 through the screening hole, thereby screening the mineral material falling on the screening plate 33.

[0035] In this embodiment, the driving member 34 includes a fixed plate 341 fixedly mounted on the top of the base plate 21 and located on one side of the mounting plate 31, a rotating shaft 342 is rotatably mounted on the fixed plate 341, a rotating disk 343 is coaxially fixedly connected to the rotating shaft 342 on the side close to the mounting plate 31, a connecting shaft 344 is fixedly mounted on the eccentric part of the rotating disk 343 close to the side of the mounting plate 31, and the connecting shaft 344 is slidably hinged to the mounting plate 31. Specifically, a sliding groove is provided on one side of the mounting plate 31, and the end of the connecting shaft 344 extends into the sliding groove. The connecting shaft 344 can slide in the sliding groove, and the connecting shaft 344 can slide in the sliding groove. 44 can rotate in the slide groove, and a motor 345 for driving the rotating shaft 342 to rotate is fixedly installed on the fixed plate 341. When in use, the motor 345 is controlled to be turned on, and the output shaft of the motor 345 rotates to drive the rotating shaft 342 to rotate on the fixed plate 341, and the turntable 343 rotates around the rotating shaft 342, so that the connecting shaft 344 makes a circular motion around the turntable 343. At this time, the connecting shaft 344 slides in the slide groove on one side of the mounting plate 31 and rotates between the mounting plate 31, so that the mounting plate 31 can reciprocate between the opposite sides of the two vertical plates 32 around the two hinge shafts 311.

[0036] In this embodiment, a knocking piece 4 connected to the connecting shaft 344 is installed on the bottom plate 21. When the connecting shaft 344 rotates around the turntable 343, the knocking piece 4 is used to intermittently knock on the bottom of the mounting plate 31. It should be noted that when the connecting shaft 344 rotates around the turntable 343 to the bottom of the turntable 343, the knocking piece 4 knocks on the bottom of the mounting plate 31. By setting the knocking piece 4, during the screening of the mineral materials crushed by the crusher body 1, when part of the crushed mineral materials fall into the sieve holes on the screening plate 33, the knocking piece 4 knocks on the bottom of the mounting plate 31, and the mineral materials falling into the sieve holes on the screening plate 33 can be knocked up, thereby effectively avoiding the situation in which part of the mineral materials are stuck in the screening plate 33 during the screening process, causing the sieve holes on the screening plate 33 to be blocked, thereby improving the screening effect of the mineral materials. Example 3

[0037] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following content:

[0038] In this embodiment, the knocking member 4 includes a hinged plate 41 fixed to the top of the mounting base 21 and located between the support plate 2 and the opposite sides of the fixed plate 341. A transmission plate 42 is hinged on the hinged plate 41. One end of the transmission plate 42 is slidably hinged to the connecting shaft 344. It is worth noting that a sliding groove is provided on the transmission plate 42, and the connecting shaft 344 is movable through the sliding groove. The connecting shaft 344 can slide in the sliding groove, and the connecting shaft 344 can rotate with the transmission plate 42. The other end is located below the mounting plate 31 and is fixedly installed with a knocking head 43 that can conflict with the bottom of the mounting plate 31. Specifically, it should be noted that when the connecting shaft 344 revolves around the turntable 343 When the turntable 343 is rotated to the bottom, the knocking head 43 comes into conflict with the bottom of the mounting plate 31. When in use, when the connecting shaft 344 makes a circular motion around the turntable 343, the connecting shaft 344 slides in the sliding groove on the transmission plate 42 and rotates between the transmission plate 42, so that the transmission plate 42 rotates back and forth on the hinged plate 41. When the connecting shaft 344 rotates around the turntable 343 to the bottom of the turntable 343, the knocking head 43 comes into conflict with the bottom of the mounting plate 31, thereby achieving a knocking effect on the bottom of the mounting plate 31. The transmission plate 42 continuously rotates back and forth on the hinged plate 41, thereby achieving an intermittent knocking effect on the bottom of the mounting plate 31.

[0039] In this embodiment, the limiting plates 5 are symmetrically fixed on the top of the mounting plate 31 and on both sides of the through hole 312. By setting the limiting plates 5, the mineral materials falling onto the screening plate 33 can be limited, effectively preventing the mineral materials from falling from the two sides of the mounting plate 31, which is convenient for collecting the mineral materials. A collecting box 6 with an open top is placed on the top of the bottom plate 21 and below the through hole 312. By setting the collecting box 6, the mineral materials falling downward through the sieve holes on the screening plate 33 can be collected, which is convenient for collecting over-crushed mineral materials.

[0040] In this embodiment, the screening plate 33 is inserted into the through hole 312 and blocks the inside of the through hole 312 . The screening plate 33 is fixed to the mounting plate 31 by bolts, so that the screening plate 33 can be easily disassembled and replaced.

[0041] In this embodiment, a feed hopper 16 connected to the feed port 12 is fixedly installed on the top of the casing 11, which is convenient for feeding the mineral material to be crushed into the feed port 12. A guide hopper 17 is fixedly installed on the bottom of the casing 11 and above the mounting plate 31, so as to guide the mineral material crushed by the crusher body 1 to the mounting plate 31.
