Description

Technical Field

[0001] The present invention relates to the technical field of jaw crushers, in particular to a jaw crusher. Background Art

[0002] Construction projects require a lot of stone. The mined stone often doesn't meet the standards for use, so the stone needs to be crushed into suitable aggregate. This is where the use of crushers comes in. One type of crusher is the jaw crusher, which consists of two jaw plates, a movable jaw and a stationary jaw, forming a crushing chamber. This simulates the movement of an animal's jaws to crush materials. Jaw crushers are simple and convenient to use, and can perform even the most basic crushing tasks, making them widely used in engineering.

[0003] Common problems of jaw crushers include material jamming. The reason for material jamming is the high moisture content and high viscosity of the material. Screening can reduce the moisture content to reduce material jamming and solve the problem of material jamming. The second is spring relaxation. The solution is to replace some parts that cannot be used or seriously affect the use. When the above two problems occur, the material will be stuck between the moving jaw and the static jaw. The solution is to stop the machine first, and then use hard rods such as crowbars to manually break the stone stuck between the moving and static jaws into small pieces. This is not only time-consuming and labor-intensive, but also has a poor crushing effect. At the same time, if the jaw crusher is large, the material is stuck deep between the moving and static jaws, and the staff need to enter between the moving and static jaws in the shell, which has a great safety hazard. For this reason, a jaw crusher is proposed. Summary of the Invention

The shaft roller 38 is located on the outer wall of the support seat 37 and is wound with a steel wire rope 313. The end of the steel wire rope 313 is connected to a lifting ring assembly 314. The end of the lifting ring assembly 314 away from the steel wire rope 313 is connected to a handheld crusher 315. A through cavity 33 is bored through the top seat 31 at the position of the handheld crusher 315.

[0035] The ladder mechanism 4 includes a standing ladder 41 , a torque sleeve 42 is provided on the top of the standing ladder 41 , two limit sleeves 43 are twisted on the torque sleeve 42 , and rods 44 are inserted inside the limit sleeves 43 , and a breast plate 45 is fixed on the top between the rods 44 .

[0036] Specifically, a servo motor 35 is fixed to the top of the gantry frame 34, and a shaft 36 is fixed to the output end of the servo motor 35. A driving wheel 310 is provided at the end of the shaft 36 away from the servo motor 35, and a driven wheel 311 is provided at the end of the shaft roller 38 away from the support seat 37. A belt 312 is provided between the driven wheel 311 and the driving wheel 310, and the inner ends of the belt 312 are respectively sleeved on the outer walls of the driving wheel 310 and the driven wheel 311.

[0037] Specifically, two bearing brackets 316 are installed on the gantry top frame 34 at the positions of the shaft 36 and the support seat 37. The bearing brackets 316 are respectively penetrated through the shaft 36 and the shaft roller 38 and are rotatably connected.

[0038] Specifically, hanging rings 39 are fixed to both side walls of the top seat 31 for connecting safety clothing.

[0039] Specifically, the outer wall of the limiting sleeve 43 close to the supporting mechanism 5 is movably connected to a spring push rod 47 through a hinge.

[0040] Specifically, the support mechanism 5 includes a support plate 51, which is installed on both ends of the top of the crushing frame 2 by bolts. Slide rails 52 are fixed at both ends of the side walls of the support plate 51 close to the ladder mechanism 4. The interior of the slide rails 52 is slidably connected to a movable seat 53, and the end of the spring push rod 47 away from the limiting sleeve 43 is movably connected to the movable seat 53 matching the position.

[0041] Specifically, a slot 57 is bored in the inner top of the slide rail 52, and a U-shaped insert plate 56 is provided on the side of the top of the support plate 51 away from the slide rail 52. The two ends of the U-shaped insert plate 56 are respectively connected with the slots 57 of matching positions, and one end of the U-shaped insert plate 56 passing through the slot 57 is located above the movable seat 53, which can enable the movable seat 53 to slide within the slide rail 52 within a limited position to avoid detachment due to excessive sliding height. When disassembling, just pull the U-shaped insert plate 56 back to make it exit the slot 57.

[0042] Specifically, a wall panel 54 is fixed to the top of the side wall between the slide rails 52, and a plurality of tension springs 55 are fixed to the side wall of the wall panel 54 close to the U-shaped inserting plate 56. The ends of the tension springs 55 away from the wall panel 54 are fixedly connected to the side walls close to the U-shaped inserting plate 56.

[0043] Specifically, the top side walls of the limiting sleeve 43 are threadedly connected with an adjusting screw 46, one end of which is inserted into the interior of the limiting sleeve 43 and contacts the side wall close to the insertion rod 44. The insertion rod 44 can slide up or down in the limiting sleeve 43, thereby changing the height of the chest guard 45 wrapped around the chest cavity, so as to adapt to the chest cavity position and comfortable standing height of different staff members. Subsequently, the insertion rod 44 is limited by passing the adjusting screw 46 through the limiting sleeve 43, thereby achieving the effect of limiting the height of the chest guard 45.

[0044] Specifically, flange support feet 32 ​​are fixed to the four corners of the bottom of the top seat 31, and the ends of the flange support feet 32 ​​away from the top seat 31 are detachably connected to the crushing frame 2 by bolts, and side support rods 48 are fixed to the side walls on both sides of the top of the standing ladder 41, and the ends of the side support rods 48 away from the standing ladder 41 are fixed to the ends close to the flange support feet 32, thereby increasing the stability of the top seat 31 and the standing ladder 41.

[0045] The working principle of this device is as follows: when the material is stuck, the machine is turned off first, and the staff climbs up the standing ladder 41. The position of the chest cavity is on the chest plate 45. The chest plate 45 prevents the body from falling due to excessive inclination when using the handheld crusher 315. After the servo motor 35 works, it drives the shaft 36, the driving wheel 310, and the belt 312 to rotate. The belt 312 drives the wire rope 313 to unwind through the driven wheel 311 and the shaft roller 38. The handheld crusher 315 drops through the position of the through-hole 33. After passing through the through-hole 33, the staff holds the handle of the handheld crusher 315, and the wire rope 313 continues to unwind until the handheld crusher 315 is inserted into the stuck material. After the handheld crusher 315 is turned on, the material is broken. Before the staff holds the handheld crusher 315, they need to wear safety clothes. The safety clothes are connected to the hanging ring 39 through the binding rope and the hook, which achieves better safety in turn. When breaking the material, the staff holds the handheld crusher 315. The breaker 315 can change the crushing position through the certain deformability of the wire rope 313, and the worker's chest can swing a certain amplitude through the twisting connection of the limit sleeve 43 and the torque sleeve 42, thereby adjusting the center of gravity of the hand-held crusher 315. When the chest guard 45 swings, the spring push rod 47 will apply force to the movable seat 53 and compress and slide to a certain amplitude, so that the worker can safely adjust the position of the hand-held crusher 315 to achieve the effect of safe crushing under the premise of safety. After the crushing is completed, the worker releases the connection between the hook and the hanging ring 39, and then gets off the ladder 41. After the servo motor 35 works, it drives the shaft roller 38 to reel in the wire rope 313 until the servo motor 35 rises from the through cavity 33 to between the top seat 31 and the gantry top frame 34, so as to avoid occupying the space between the top seat 31 and the crushing frame 2 and affecting the normal feeding work.

[0046] The transmission mechanism and the dynamic and static jaw mechanisms of the jaw crusher are existing and public technologies and will not be described in detail in this application.

[0047] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
