Abstract
Description
Technical Field
[0001] This utility model relates to a jaw multi-cylinder crusher, specifically a clearing cylinder for a jaw multi-cylinder crusher. Background Technology
[0002] Jaw crushers, also known as jaw breakers or tiger's mouth crushers, consist of a crushing chamber formed by two jaw plates: a movable jaw and a fixed jaw. They mimic the jaw movements of an animal to crush materials. They are widely used in the crushing of various ores and large materials in industries such as mining and metallurgy, building materials, highways, railways, water conservancy, and chemicals.
[0003] In actual use, crushers crush materials through the reciprocating motion of the moving jaw. During this process, when material becomes stuck between the moving and stationary jaws due to its inability to be crushed, other materials entering the jaws will be blocked by the stuck material. Currently, in such cases, the crusher must be stopped, all material stuck between the jaws removed, and then the crusher restarted before new material is fed in. This operation is cumbersome and inefficient. Furthermore, when material is stuck between the jaws, it is difficult to remove due to the tightness of the jam. Alternatively, when material becomes stuck and cannot be crushed, the feeding of subsequent materials can be suspended, and operators can use hammers or other tools to break the stuck material. However, this method is cumbersome and labor-intensive, and after a blockage occurs, the material at the top must be removed before the stuck material can be hammered. Therefore, a clearing cylinder for a jaw multi-cylinder crusher is proposed. Utility Model Content
[0004] The purpose of this invention is to solve the above problems by proposing a clearing cylinder for a jaw multi-cylinder crusher.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a clearing cylinder for a jaw crusher, characterized by including a clearing cylinder body connecting the jaw crusher body and the upper moving jaw of the jaw crusher, and an elastic buffer component that provides elastic buffering for the clearing cylinder body during the reciprocating motion of the moving jaw plate and is movably connected to the jaw crusher body at one end; the elastic buffer component includes a connecting sleeve that movably connects the clearing cylinder and the jaw crusher body, and a spring placed inside the connecting sleeve that provides elastic buffering for the clearing cylinder.
[0006] More preferably, the clearing cylinder body includes a cylinder body slidably connected to the connecting sleeve and a piston connected to the moving jaw of the jaw crusher.
[0007] More preferably, the cylinder body is provided with a limiting platform that is slidably connected to the connecting sleeve, and springs are fitted on both sides of the cylinder body, with the springs located between the limiting platform and the two ends of the connecting sleeve.
[0008] More preferably, the connecting sleeve is divided into two parts, namely a separate connecting sleeve one and a connecting sleeve two, and the connecting sleeve one and the connecting sleeve two are provided with connecting blocks for easy connection.
[0009] More preferably, one end of the connecting sleeve is provided with a movable connecting block for movable connection with the main body of the jaw crusher.
[0010] More preferably, the cleaning cylinder body is provided with an oil inlet and outlet, and the oil inlet and outlet are equipped with a filter screen.
[0011] The beneficial effects of this utility model are as follows: By setting the body of the clearing cylinder, when the material is stuck between the moving jaw and the stationary jaw, the body of the clearing cylinder is activated to drive the moving jaw to move and widen the distance between the moving jaw and the stationary jaw, so that the stuck material falls out. Then the moving jaw is reset by the clearing cylinder, and the material crushing action continues after the reset.
[0012] By setting up an elastic buffer, one end of the cleaning cylinder is movably connected to the main body of the jaw crusher, while the moving jaw plate provides bidirectional elastic buffering for the reciprocating motion of the cleaning cylinder during the reciprocating motion of the moving jaw plate. This avoids the cleaning cylinder being directly connected to the main body of the jaw crusher, which could lead to collisions and impacts between the cleaning cylinder and the main body of the jaw crusher during the reciprocating motion of the moving jaw plate, resulting in damage.

[0016] The following description, in conjunction with the accompanying drawings, further illustrates the cleaning cylinder for a jaw multi-cylinder crusher according to this utility model.
[0017] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.
[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0019] See Figure 1-2 As shown, a clearing cylinder for a jaw crusher is characterized by including a clearing cylinder body 1 that connects the jaw crusher body and the upper moving jaw of the jaw crusher, and an elastic buffer 2 that provides elastic buffering for the clearing cylinder body 1 during the reciprocating motion of the moving jaw plate and is movably connected to the jaw crusher body at one end; the elastic buffer 2 includes a connecting sleeve 3 that movably connects the clearing cylinder and the jaw crusher body, and a spring 4 placed in the connecting sleeve 3 that provides elastic buffering for the clearing cylinder.
[0020] By setting the elastic buffer 2, one end of the cleaning cylinder is movably connected to the main body of the jaw crusher, and at the same time, it plays a two-way elastic buffer role on the reciprocating motion of the cleaning cylinder during the reciprocating motion of the moving jaw plate. This avoids the cleaning cylinder being directly connected to the main body of the jaw crusher, which would cause collision and impact between the cleaning cylinder and the main body of the jaw crusher during the reciprocating motion of the moving jaw plate, resulting in damage.
[0021] In one embodiment, the clearing cylinder body 1 includes a cylinder body 5 slidably connected to the connecting sleeve 3 and a piston 6 connected to the moving jaw of the jaw crusher.
[0022] In one embodiment, the cylinder body 5 is provided with a limiting platform 7 that is slidably connected to the connecting sleeve 3. Springs 4 are fitted on both sides of the cylinder body 5 of the limiting platform 7, and the springs 4 are located between the limiting platform 7 and the two ends of the connecting sleeve 3. With the setting of the limiting platform 7 and the springs 4, during the reciprocating motion of the cleaning cylinder with the moving jaw plate, the limiting platform 7 squeezes the springs 4 on both sides, and the springs 4 on both sides form an elastic buffer for the limiting platform 7. At the same time, the setting of the limiting platform 7 limits the position of the cleaning cylinder in the connecting sleeve 3.
[0023] In one embodiment, the connecting sleeve 3 is divided into two parts, namely a first connecting sleeve 31 and a second connecting sleeve 32. The first connecting sleeve 31 and the second connecting sleeve 32 are provided with connecting blocks 33 for easy connection. By setting the connecting sleeve 3 into two parts, it is convenient to install or remove the cleaning cylinder into the connecting sleeve 3. And by setting the connecting blocks 33, the first connecting sleeve 31 and the second connecting sleeve 32 can be locked together by bolts.
[0024] In one embodiment, one end of the connecting sleeve 3 is provided with a movable connecting block 8 for movably connecting with the jaw crusher body; through the setting of the movable connecting block 8, a pin can be installed on the movable connecting block 8, and the connecting sleeve 3 can rotate along the pin by movably connecting with the jaw crusher body through the pin.
[0025] In one embodiment, the cleaning cylinder body 1 is provided with an oil inlet / outlet 11, and the oil inlet / outlet 11 is equipped with a filter screen 12; the filter screen 12 filters the oil and gas entering the cleaning cylinder, preventing impurities from entering the cleaning cylinder.
[0026] In use, the following steps are taken: First, two springs 4 are fitted onto the body 1 of the clearing cylinder and positioned on both sides of the limiting platform 7. Then, the body 1 of the clearing cylinder and the two springs 4 are installed into the connecting sleeve 31. During installation, the springs 4 on both sides are compressed. Then, the connecting sleeve 32 is closed with the connecting sleeve 31. Finally, the two connecting blocks 33 are locked with bolts. Then, the movable connecting block 8 is connected to the main body of the jaw crusher by a pin. Then, one end of the piston 6 is connected to the moving jaw on the jaw crusher. During use, as the moving jaw on the jaw crusher reciprocates, it compresses the body 1 of the clearing cylinder, which in turn compresses the springs 4 on both sides. The springs 4 provide elastic buffering on both sides. When the crusher is stuck and material cannot be discharged, the body 1 of the clearing cylinder is activated, which drives the piston 6 to move and thus the moving jaw plate to move. This opens the gap between the moving jaw plate and the stationary jaw, allowing the stuck material to fall down. Then, the moving jaw plate is reset to perform the crushing action, preventing material from getting stuck between the moving jaw plate and the stationary jaw plate and causing blockage.
[0027] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
