Description

Technical Field

[0001] The utility model relates to the technical field of jaw crushers, in particular to a jaw crusher used in mines. Background Art

[0002] A jaw crusher usually consists of two jaw plates, a movable jaw and a static jaw, forming a crushing chamber with a larger upper part and a smaller lower part. During operation, the movable jaw plate performs periodic reciprocating motion relative to the fixed jaw plate. When the two jaw plates are separated, the material enters the crushing chamber and the finished product is discharged from the bottom; when they are close, the material between the two jaw plates is crushed by the extrusion; Patent No. CN202122988034.4 discloses a rapid prototyping lampshade mold. When the movable jaw plate and the fixed jaw plate extrude the material, the raised triangular teeth can hook the material and play a role in blocking the material. The shorter trapezoidal teeth have a larger surface area and strength, which can effectively crush the material, thereby avoiding damage to the protruding sharp teeth; however, when the jaw crusher is crushing the ore, some of the ore splashes inside the equipment with the extrusion vibration, and it is easy to fly out from the opening at the top of the equipment, which can easily cause abrasions to the staff around the equipment. For this reason, we propose a jaw crusher for mining. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a jaw crusher for mines.

[0004] The technical solution adopted by the utility model to solve the technical problem is a jaw crusher for mining, comprising a machine body, a shell cover is assembled at the top open end of the machine body by bolts, and bearing seats are assembled on both sides of the inner circumference of the shell cover, and there are two groups of bearing seats, a horizontal shaft for adjustment is rotatably mounted between the two groups of bearing seats, and a pipe sleeve is sleeved and mounted on the outer circumference of the horizontal shaft, and a baffle for splash prevention is integrally constructed on the opposite sides of the two groups of pipe sleeves;

[0005] The inner surface of the shell cover and the outer surface of the baffle are both equipped with ear seats that can be used for connection, and there are multiple groups of ear seats. A shock-absorbing cylinder is hinged between two groups of ear seats through a rotating shaft, and a spring located between the two groups of ear seats is installed on the outer periphery of the shock-absorbing cylinder.

[0006] By adopting the above technical solution, when the jaw crusher is used to crush ore, the shell cover installed on the top of the body is convenient for protecting the feeding end of the body, and at the same time, the two groups of baffles inside the shell cover are hinged to each other through the pipe sleeve and the horizontal axis inside the shell cover, and the horizontal axis is convenient to rotate due to the bearing seat, so that the two groups of baffles are convenient to swing automatically, so that they are convenient to open and close, and convenient to automatically close the open end after adding ore raw materials to the inside of the shell cover, thereby reducing the situation of ore splashing from the inside of the body, so that the jaw crusher can crush the ore more stably;

[0007] When the baffle is squeezed by the ore to open the closed feed end of the shell cover, the springs between the two sets of ear seats between the baffle and the inner periphery of the shell cover facilitate returning and pushing the baffle back, so that the baffle can return and continue to close the feed port of the shell cover. At the same time, the shock-absorbing cylinder provides a certain buffering performance for the baffle, which is convenient for reducing the situation in which the baffle is directly impacted against the inner wall of the shell cover and caused damage, so that the baffle can operate more stably.

[0008] Specifically, a corrugated rubber hose located on the outer periphery of the spring is installed between the two groups of ear seats.

[0009] By adopting the above technical solution, the corrugated hose can be easily extended and retracted, and can protect the shock absorber tube and the spring, so that the two can operate more stably.

[0010] Specifically, a sponge pad is bonded to the outer peripheral surface of the baffle.

[0011] By adopting the above technical solution, the sponge pad has certain elasticity and protection, which is convenient for reducing the direct damage caused by friction when the ore contacts the baffle.

[0012] Specifically, both side end surfaces of the outer periphery of the transverse axis are equipped with bayonet pins.

[0013] By adopting the above technical solution, the bayonet pins can be easily installed at both ends of the horizontal axis, which can reduce the separation between the horizontal axis and the two sets of bearing seats, so that the horizontal axis can operate stably and is easy to disassemble.

[0014] Specifically, an inclined block is welded on one side of the outer periphery of the shell cover close to the bottom end, and there are multiple groups of inclined blocks.

[0015] By adopting the above technical solution, the inclined block is convenient for reinforcing the side of the shell cover close to the machine body, thereby improving the stability of the shell cover after being connected to the machine body.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 2. The technical solution of the present application is designed with ear seats, shock-absorbing cylinders and springs. When the baffle is squeezed by the ore to open the closed feed end of the shell cover, the springs between the two sets of ear seats between the baffle and the inner periphery of the shell cover are convenient for returning and pushing the baffle back, so that the baffle can return and continue to close the feed port of the shell cover. At the same time, the shock-absorbing cylinder provides a certain buffering performance for the baffle, which is convenient for reducing the situation where the baffle is directly impacted against the inner wall of the shell cover and caused damage, so that the baffle can operate more stably.
