Description

Technical Field

[0001] The utility model belongs to the technical field of crushers and relates to a jaw crusher with a shock-absorbing function. Background Art

[0002] Jaw crusher is commonly known as jaw crusher, also known as tiger mouth. It consists of two jaw plates, movable jaw and static jaw, to form a crushing chamber. It simulates the movement of two jaws of animals to complete material crushing operations. The movable jaw makes periodic reciprocating motion against the static jaw, sometimes separated and sometimes close. When separated, the material enters the crushing chamber and the finished product is discharged from the bottom; when close, the material loaded between the two jaw plates is squeezed, bent and split to be crushed.

[0003] Due to the practicality of jaw crushers, they are widely used in the crushing of various ores and bulk materials in the mining and smelting, building materials, highways, railways, water conservancy and chemical industries. However, the existing jaw crushers are limited by their structure and design in actual use. In the process of crushing bulk materials, the jaw crusher will vibrate due to the reciprocating motion of the movable jaw. When the vibration amplitude is too large, the internal parts of the crusher will be affected and damaged, thereby reducing the service life of the crusher. At the same time, the large vibration will also affect the stability of the crusher, thereby reducing the safety of the crusher when in use. Utility Model Content

Buffer springs 10 located on the outside of the limiting rod 7 are fixedly installed on the opposite surfaces of the four slide blocks 8.

[0024] When the jaw crusher with shock absorption function vibrates, the outer shell 1 will move downward along the inner surface of the column 4 with the supporting legs 2 and the damping block 3. At the same time, since the bottom end of the outer shell 1 is hinged to the buffer rod 9 and the other end of the buffer rod 9 is hinged to the top of the slider 8, as the outer shell 1 moves, the buffer rod 9 will push the slider 8 to move along the outer surface of the limit rod 7, thereby stretching the buffer spring 10. Under the restoring action of the buffer spring 10, the slider 8 will be forced to return to its original position, thereby reducing the vibration of the crusher and improving the stability of the crusher.

[0025] Among them, Figure 1 , Figure 2 , Figure 4As shown, a first motor 11 is fixedly installed on the front side of the middle of the left end of the housing 1, and a rotating shaft 12 is fixedly sleeved on the other end of the output shaft of the first motor 11, and a driving wheel 13 is fixedly sleeved on the top of the outer surface of the rotating shaft 12.

A movable jaw plate 18 is movably sleeved in the middle of the outer surface of the spindle 14, and the movable jaw plate 18 is movably sleeved on the inner surface of the shell 1; when the driving wheel 13 rotates, the driven wheel 15 will rotate with the eccentric shaft 14 and the flywheel 17 through the conveyor belt 16, thereby causing the movable jaw plate 18 to reciprocate up and down; a fixed rod 19 is fixedly sleeved on the top of the left end of the shell 1, and a static jaw plate 20 is movably sleeved on the outer surface of the fixed rod 19, and the outer surface of the static jaw plate 20 is movably sleeved on the inner surface of the shell 1, and a sliding plate is provided in the middle of the left end of the static jaw plate 20.

A movable block 27 is threadedly sleeved on the middle part of the outer surface of the threaded rod 26. The right end of the movable block 27 is movably connected to the left end of the shell 1, and a push rod 28 is hinged on the left end of the movable block 27. The other end of the push rod 28 is hinged to the top of the vertical block 24. When the second motor 25 is started, the threaded rod 26 will rotate, so that the movable block 27 moves with the push rod 28, and then the push rod 28 generates a thrust on the vertical block 24.

[0026] like Figure 3 and Figure 5As shown, an adjusting block 29 is fixedly installed at the bottom of the right inner wall of the shell 1, and a first connecting rod 30 is hinged at the left end of the adjusting block 29, and the other end of the first connecting rod 30 is hinged at the bottom of the right end of the movable jaw plate 18. A fixed block 31 located below the adjusting block 29 is fixedly installed on the right inner wall of the shell 1, and a second connecting rod 32 is movably sleeved on the left end of the fixed block 31, and the left end of the second connecting rod 32 is hinged to the bottom of the right end of the movable jaw plate 18, and a connecting spring 33 is fixedly installed on the right end of the second connecting rod 32, and the other end of the connecting spring 33 is fixedly installed at the right end inside the fixed block 31. Due to the existence of the adjusting block 29, the first connecting rod 30, the second connecting rod 32 and the connecting spring 33, the movement of the movable jaw plate 18 will be assisted.

[0027] The working principle of the jaw crusher with shock absorption function of the utility model is as follows: first, the second motor 25 is started to rotate the threaded rod 26, and the movable block 27 threadedly sleeved with the threaded rod 26 will move along the outer surface of the housing 1 with the right end of the push rod 28, so that the left end of the push rod 28 generates a thrust on the vertical block 24, pushing the vertical block 24 to move with the slide bar 22 through the connecting block 23, and then the static jaw plate 20 rotates with the fixed rod 19 as the axis, until the spacing between the static jaw plate 20 and the movable jaw plate 18 meets the requirements, and each mechanism The mutual cooperation realizes the adjustment of the inclination angle of the static jaw plate 20, thereby controlling the crushing degree of bulk materials, and then the first motor 11 can be started, so that the rotating shaft 12 drives the driving wheel 13 to rotate. Since the driving wheel 13 is connected to the driven wheel 15 through the conveyor belt 16, the driven wheel 15 will rotate with the eccentric shaft 14 and the flywheel 17, and then cooperate with the first connecting rod 30, the second connecting rod 32 and the connecting spring 33 to make the movable jaw plate 18 reciprocate, and then the bulk materials can be poured between the movable jaw plate 18 and the static jaw plate 20 for crushing.

[0028] When the jaw crusher vibrates during operation, the outer shell 1 will move downward along the inner surface of the column 4 with the supporting legs 2 and the damping block 3. At this time, the buffer rod 9 hinged to the bottom end of the outer shell 1 will generate a thrust on the top of the slider 8, pushing the slider 8 to move along the outer surface of the limit rod 7, thereby stretching the buffer spring 10. Under the restoring action of the buffer spring 10, the slider 8 will be forced to return to its original position. The mutual cooperation between the damping block 3, the column 4, the slider 8, the buffer rod 9 and the buffer spring 10 will slow down the vibration of the jaw crusher, thereby improving its stability and extending the service life of the crusher.
