Background Technology

[0002] Eccentric roll crushers are widely used in the mining industry, primarily for crushing ores. During operation, the adjustable positioning and locking mechanism is a crucial component. Existing adjustable positioning and locking mechanisms for eccentric roll crushers are overly complex and difficult to apply to laboratory-scale eccentric roll crushers. Therefore, there is an urgent need for an adjustable positioning and locking mechanism suitable for laboratory-scale eccentric roll crushers. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable positioning and locking mechanism for the lower jaw plate of a laboratory-type eccentric roller crusher, which solves the problems of positioning and locking and opening size adjustment of the lower jaw plate in existing laboratory-type eccentric roller crushers.

[0004] The above-mentioned objective of this utility model is achieved through the following technical solution:

[0005] An adjustable positioning and locking mechanism for the lower jaw plate of a laboratory-type eccentric roller crusher includes an adjustable positioning mechanism and a locking mechanism, which are respectively fixed on a support plate 1. The two sides of the support plate 1 are fixed to the frame of the laboratory-type eccentric roller crusher by bolts. The locking mechanism includes a locking rod 10, a locking slider 9, a disc 13, a spring 11, and a spring locking block 12. The spring 11 between the support plate 1 and the spring locking block 12 relieves the working stress of the lower jaw. One end of the locking rod 10 is welded to the locking slider 9. The locking slider 9 is connected to the lower jaw locking connecting block 3 by a pin 14 and a rivet 8. The lower jaw locking connecting block 3 is fixed on the lower jaw plate 2. At the other end of the locking rod 10, the disc 13 and the spring locking block 12 are respectively fixed on the locking rod 10. The spring 11 is sleeved on the locking rod 10, and its two ends abut against the spring locking block 12 and the disc 13, respectively.

[0006] The disc 13 and the hole on the lower side of the support plate 1 are engaged with each other through surface contact.

[0007] The adjustable positioning mechanism includes an adjusting slider 4, an adjusting threaded rod 7, an adjusting nut 5, and a limiting nut 6. The adjusting slider 4 rests on the lower jaw plate 2 to position the lower jaw plate 2. The adjusting threaded rod 7 passes through the support plate 1 and is welded to the adjusting slider 4. The adjusting nut 5 and the limiting nut 6 are respectively connected to the adjusting threaded rod 7 and are located on both sides of the support plate 1. The position of the adjusting slider 4 is adjusted by the threaded engagement between the adjusting nut 5 and the adjusting threaded rod 7.

[0008] The beneficial effects of this utility model are as follows: It provides an adjustable positioning and locking mechanism for the lower jaw plate of a laboratory-type eccentric roller crusher. By adjusting the relative rotation of the threaded rod and the adjusting nut, the adjusting slider moves axially, further pushing the lower jaw, thereby adjusting the position of the lower jaw of the laboratory-type eccentric roller crusher. A locking mechanism is designed, in which the locking slider and the lower jaw locking connecting block are connected by a pin. The position of the lower jaw can be adjusted in real time as needed, and it can adjust the discharge port size of the eccentric roller crusher and lock the lower jaw plate. It can simulate the real working environment of the eccentric roller crusher, is easy to operate, and has high practicality. Attached Figure Description

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. To make the above-mentioned objects, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] See Figures 1 to 3As shown, the adjustable positioning and locking mechanism of the lower jaw plate of the laboratory-type eccentric roller crusher of this utility model is fixedly connected to the frame of the eccentric roller crusher by a support plate 1 and bolts. It includes an adjustable positioning mechanism and a locking mechanism. The adjustable positioning mechanism is connected to the locking mechanism through the support plate 1. The locking mechanism is composed of a locking slider 9, a locking rod 10, a disc 13, a spring 11, and a spring locking block 12. The working stress of the lower jaw is relieved by the spring 11 between the support plate 1 and the spring locking block 12.

[0016] The locking mechanism is connected to the lower jaw plate 2 of the eccentric roller crusher by a pin 14 between the lower jaw locking connecting block 3 and the spring locking block 12, and is positioned by rivets 8.

[0017] The support plate 1 is connected to the frame body via bolts, disc 13, and limit nut 6. The support plate 1 has a hole on its lower side that contacts the disc surface. The support plate 1 and the frame body are connected by threads.

[0018] The adjustable positioning mechanism comprises an adjusting slider 4, an adjusting threaded rod 7, an adjusting nut 5, and a limiting nut 6. The adjusting slider 4 is positioned against the lower jaw to locate the lower jaw plate 2. The position of the adjusting slider 4 is adjusted by the threaded engagement between the adjusting nut 5 and the adjusting threaded rod 7.

[0019] The support plate 1 is used to fix the adjustable positioning mechanism and the locking mechanism. The adjusting slider 4 is used to position the lower jaw plate 2. The adjusting nut 5 and the adjusting threaded rod 7 are engaged to adjust the position of the adjusting slider 4. The limiting nut 6 is used to determine the relative position of the support plate 1 and the adjustable positioning mechanism. The locking slider 9 and the lower jaw locking connecting block 3 are connected by a pin 14 to determine the opening size of the lower jaw. The lower jaw plate 2 is locked by a rivet 8. The disc 13 is used to determine the relative position of the support plate 1 and the locking mechanism. The spring 11 between the spring locking block 12 and the disc 13 is used to reduce the force during operation.

[0020] See Figures 1 to 3 As shown, the working process of the adjustable positioning and locking mechanism of the lower jaw of the laboratory-type eccentric roller crusher of this utility model is as follows:

[0021] The support plate 1 is bolted to the frame on both sides. The upper side has a hole for connecting to the adjustable positioning mechanism via a limit nut 6. The lower side is fixed to the locking mechanism via a mating disc 13. The arc surface of the adjusting slider 4 at the front end of the adjustable positioning mechanism rests against the lower jaw plate 2 for positioning. The adjusting threaded rod 7 is welded to the adjusting slider 4 and threadedly engages with the adjusting nut 5. To adjust the position, the adjusting nut 5 is tightened, causing the adjusting threaded rod 7 to move, controlling the axial movement of the adjusting slider 4, which in turn moves the lower jaw plate 2 to complete the adjustment. The locking mechanism is connected to the lower jaw locking block 3 via a pin 14. A hole is located at one end of the pin 14, which is fixed with a rivet 8. The locking slider 9 is welded to the locking rod 10. At the other end of the locking rod 10, a spring 11 is located between the spring locking block 12 and the disc 13 to reduce the force generated during operation of the laboratory-type eccentric roller crusher.
