Description

Technical Field

[0001] This utility model belongs to the field of mica sheet processing and relates to crushing technology, specifically a jaw crusher for mica sheets. Background Technology

[0002] Jaw crushers are medium-sized crushing equipment used to crush various ores and large materials. Mica ore is generally processed into mica flakes by jaw crushers.

[0003] Jaw crushers crush internal mica ore through the collision of movable and fixed jaw plates. The crushed mica ore falls to the ground as the movable jaw plate moves, and the dust generated during the crushing also falls to the ground. Existing jaw crushers generally allow the crushed ore and dust to come into direct contact with the ground. When the dust comes into contact with the ground, it will disperse to all sides due to the impact force, affecting the air quality of the working environment and endangering the health of the operators. At the same time, some dust is trapped between the crushed ore due to the compression of the crushed ore, requiring multiple screenings during subsequent ore collection or screening, making the process relatively complicated.

[0004] Therefore, this utility model proposes a jaw crusher for mica sheets. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a jaw crusher for mica flakes, which solves the problem that after crushing with existing jaw crushers, the ore generally falls to the ground along with dust, which affects the environment and increases the complexity of subsequent operations.

[0030] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] like Figure 1-6 As shown, a jaw crusher for mica flakes includes a crusher body 1, a base 2 fixedly connected to the surface of the crusher body 1, a discharge port inside the base 2, and a guide mechanism between the base 2 and the discharge port. The guide mechanism includes:

[0032] A plurality of guide troughs 31 are provided, each of which is located inside the base 2 and extends through one side of the base 2. Each guide trough 31 is connected to the discharge port. A plurality of guide blocks 32 are fixedly connected inside the base 2. The number of guide blocks 32 is the same as the number of guide troughs 31. Each guide block 32 and each guide trough 31 form a group. The distance between the guide block 32 and the crusher body 1 in the same group is less than the distance between the guide trough 31 and the crusher body 1. The side of the guide block 32 away from the guide trough 31 is arc-shaped.

[0033] A plurality of filter screens 33 are provided, each of which is detachably disposed between the base 2 and the guide trough 31. The filter screens 33 are all inclined. The base 2 has two outlet grooves 34 inside, which are symmetrically disposed relative to the base 2. The outlet grooves 34 and the guide trough 31 are perpendicular to each other in space. An adsorption block is detachably connected inside the outlet groove 34. A collection block 35 is slidably connected to the bottom of the discharge port.

[0034] In practical applications, the mica sheet is processed by a jaw crusher. The feed inlet inside the base 2 is divided into several spaces by the feed chute 31 and the discharge chute 34. After the crusher body 1 crushes the ore and dust, they move to the bottom of the feed inlet under the action of gravity. During the movement, the crushed ore stops moving under the action of the filter screen 33. The dust and smaller crushed ore continue to move downwards. After they come into direct contact with the collection block 35, the dust will disperse to all sides and then be discharged outwards along the discharge chute 34. During the dust discharge process, under the action of the adsorption block, some impurities inside cannot be discharged, thereby reducing the impact of dust generated by the crusher body 1 on the working environment. Moreover, the dust and crushed ore are separated under the action of the filter screen 33, which facilitates the subsequent processing of the crushed ore.

[0035] In some specific implementations, a plurality of placement blocks 41 are slidably connected inside the base 2. The placement blocks 41 are inclined inside the base 2. The placement blocks 41 are slidably connected to the filter screen 33. A limit component is provided between the placement blocks 41 and the filter screen 33. A vibration component is provided between the placement blocks 41 and the base 2.

[0036] In a further embodiment, the limiting component includes a limiting block 42 rotatably disposed on the surface of the placement block 41, and a ring spring 43 fixedly connected between the limiting block 42 and the placement block 41; a positioning block is fixedly connected to the side of the placement block 41 away from the limiting block 42, the distance between the limiting block 42 and the positioning block is equal to the length of the filter screen 33, a positioning groove 44 is formed on the surface of the positioning block, and a positioning shaft 45 is fixedly connected to the surface of the filter screen 33, the positioning shaft 45 being adapted to the positioning groove 44; by setting the rotatable limiting block 42 and the positioning block with the positioning groove 44 at different positions of the placement block 41, the filter screen 33 can be restricted to the surface of the placement block 41, and the position of the filter screen 33 will change as the position of the placement block 41 changes;

[0037] In a further embodiment, the vibration assembly includes a drive rod 51 rotatably disposed inside the base 2. Multiple drive columns are fixedly connected to the surface of the drive rod 51. The distance between the drive columns and the center of the drive rod 51 is less than the radius of the drive rod 51 and greater than zero. A drive block 52 is rotatably connected to the surface of each drive column. A central connecting rod 53 is rotatably connected to the end of the drive block 52 away from the drive column. An inclined groove 54 is formed inside the base 2. The cross-section of the central connecting rod 53 is cross-shaped. The central connecting rod 53 is adapted to the inclined groove 54. The end of the central connecting rod 53 away from the drive column is slidably connected to the placement block 41. Through the sliding and inclined movement of one side of the central connecting rod 53, the placement block 41 on the other side can be moved upwards. This causes the drive rod 51 to drive the drive block 52 to reciprocate, which in turn causes the placement block 41 to reciprocate, thereby causing the filter screen 33 to reciprocate. After the surface of the filter screen 33 is broken, the ore vibrates.

[0038] In a further embodiment, a motor is fixedly connected inside the base 2, and the motor is electrically connected to an external power source. Several locking teeth 61 are fixedly connected to the end of the motor's output shaft. A driving rod 62 is slidably connected inside the base 2, and a driving spring is fixedly connected between the driving rod 62 and the base 2. The distance between the driving rod 62 and the guide groove is less than the distance between the driving rod 62 and the filter screen 33. A locking rod 63 is slidably connected inside the drive rod 51, and the locking rod 63 is rotatably connected to the driving rod 62. The locking rod 63 is fixedly connected to the side near the motor. The base 2 is equipped with a number of passive teeth 64, and the number of locking teeth 61 is an integer multiple of the number of passive teeth 64. The locking teeth 61 are adapted to the passive teeth 64. Through the motor, locking teeth 61 and passive teeth 64 inside the base 2, the rotation of the drive rod 51 can be directly controlled by the motor. The contact between the locking teeth 61 and the passive teeth 64 needs to be driven by the drive rod 62. The sliding force of the drive rod 51 is driven by the moving dust or airflow, which can ensure that the crushed ore falls and causes the placement block 41 to move, and avoid the airflow generated by the movement of the filter screen 33 before the crushed ore falls, which affects the falling path of the dust.

[0039] The working principle of this utility model:

[0040] When the crusher body 1 is working, the motor is started. After crushing, the ore and dust fall down along the feed inlet. The crushed ore falls onto the surface of the filter screen 33. After the dust falls, it impacts the drive rod 62, which moves down. The dust moves towards the guide groove and is discharged, causing the passive tooth 64 and the locking tooth 61 to contact. The motor drives the drive rod 51 to rotate. The rotation of the drive rod 51 causes the position of the drive column to change, which in turn drives the drive block 52 to move. The movement of the drive block 52 causes the central rotating rod 53 to slide, causing the central rotating rod 53 to move obliquely towards the side of the placement block 41. In turn, the placement block 41 moves, and the placement block 41 drives the filter screen 33 to move back and forth. After crushing, the ore falls down along the guide chute 31.

[0041] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
