Description

Technical Field

[0001] This utility model relates to the field of jaw crusher technology, specifically a high-efficiency stone crusher. Background Technology

[0002] Jaw crushers are widely used in mining, metallurgy, and building materials industries, offering advantages such as simple structure, large crushing ratio, and convenient maintenance. Jaw crushers primarily rely on the compressive force generated between the periodic oscillation of the moving jaw plate and the fixed jaw plate to repeatedly squeeze and shear the rock entering the crushing chamber, achieving crushing. However, in actual crushing processes, a "bridging" phenomenon often occurs when dealing with larger rocks or multiple small rocks stacked together. This means the rock becomes stuck between two jaw plates, unable to slide or fall. Even with repeated movement of the moving jaw, sufficient crushing force cannot be applied to the rock, leading to interruptions in the crushing process.

[0003] In existing technologies, when encountering this situation, the rock is usually broken by manually striking it with a sledgehammer, or by using tools such as iron bars or crowbars to clear it.

[0004] However, manual processing is inefficient and labor-intensive, and it also poses significant safety hazards (the crusher does not stop when manually hammering). Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1:

[0033] Please see Figure 1 and Figure 2 This embodiment proposes a high-efficiency stone crusher, which is an improvement on the existing jaw crusher 1, such as... Figure 1 As shown, the basic structure is a jaw crusher 1 with a crushing chamber 2, and the crushing chamber 2 is also equipped with a fixed jaw plate 3 and a moving jaw plate 4.

[0034] In this embodiment, a crossbeam 8 is installed above the opening of the crushing chamber 2 via a support device. A sliding groove 9 is formed on the crossbeam 8 along its length, and a sliding plate 10 is slidably installed in the sliding groove 9. Figure 2 As shown, the sliding plate 10 is fixedly installed on the outer wall of the impact cylinder 11, and the output shaft of the impact cylinder 11 faces downward and is fixedly connected to the crushing cone 12;

[0035] By setting an impact cylinder 11 above the crushing chamber 2, large rocks or multiple piled stones stuck between the fixed jaw plate 3 and the moving jaw plate 4 can be longitudinally impacted and crushed, which significantly improves crushing efficiency, reduces manual intervention, improves the degree of automation of the equipment, and solves the problem of crushing failure caused by stone jamming in the existing technology.

[0036] By sliding the sliding plate 10 within the sliding groove 9, the impact cylinder 11 can slide along the length of the crossbeam 8, allowing the impact position to be adjusted according to actual conditions, thus improving the adaptability and practicality of the equipment.

[0037] In this embodiment, the supporting device consists of support column 5 and positioning column 6, which respectively support both ends of the crossbeam 8. The support column 5 and positioning column 6 are as follows: Figure 1 The components shown are installed on both sides of the jaw crusher 1 housing, specifically as follows: Figure 2 As shown, the bottom ends of the support column 5 and the positioning column 6 are both fixedly connected to the mounting plate 7, and the mounting plate 7 is fixedly installed on the shell of the jaw crusher 1 by mounting bolts.

[0038] To facilitate the installation of the mounting plate 7, through holes are provided on the mounting plate 7, and bolt holes are provided at the corresponding installation positions on the jaw crusher 1 housing.

[0039] Example 2:

[0040] Please see Figure 2 and Figure 3 Based on Embodiment 1, in this embodiment, a rotating shaft 13 is fixedly installed on one side of the bottom of the crossbeam 8, and the rotating shaft 13 is rotatably connected to the support column 5. A locator is fixedly installed on the other side of the bottom of the crossbeam 8, and the locator is movably engaged in the positioning seat. The positioning seat is fixedly installed on the top of the positioning column 6.

[0041] like Figure 3 As shown, the locator is a bottom shaft 14 and a clamping plate 15 fixedly installed at the bottom end of the bottom shaft 14. The bottom shaft 14 is fixedly installed at the bottom of the crossbeam 8.

[0042] The positioning base consists of an upper limit plate 16 and a lower limit plate 17 arranged in parallel, one above the other, both fixedly mounted on the positioning post 6. The upper limit plate 16 is also provided with a shaft groove 18 for the bottom shaft 14 to enter. In addition, the clamping plate 15 is clamped between the upper limit plate 16 and the lower limit plate 17, and its diameter is greater than the width of the shaft groove 18.

[0043] The design of one end of the crossbeam 8 allows it to be rotated open, completely exposing the space above the crushing chamber 2, thus facilitating the pouring of stones into the crushing chamber 2 from a height.

[0044] When the clamping plate 15 is located between the upper limit plate 16 and the lower limit plate 17, the upper and lower limits of the upper limit plate 16 and the lower limit plate 17 can effectively ensure the stability of the impact cylinder 11 during impact.
