Description

Technical Field

[0001] This utility model relates to the technical field of feeding buffer devices for jaw crushers, specifically a feeding buffer device for jaw crushers. Background Technology

[0002] The slag beneficiation plant's coarse crushing system is equipped with a jaw crusher, mainly used for crushing smelting slag ≤500mm. It is a key piece of equipment in the coarse crushing system. The eccentric shaft is driven by an electric motor through a pulley to rotate, causing the moving jaw to periodically approach and move away from the fixed jaw. The material is crushed by the squeezing and bending action of the two jaw plates, which reduces the material size from large to small and causes it to fall gradually until it is discharged from the discharge port as ≤120mm material.

[0003] Jaw crusher feed buffer devices are crucial auxiliary equipment in mining crushing systems. Their core function is to effectively mitigate the impact of falling materials through structural design and material optimization, protecting downstream equipment (such as conveyor belts and silos) and improving production efficiency.

[0004] Existing jaw crusher feeding buffer devices typically use adjusting the slope of the discharge plate or adding buffer blocks to slow down and buffer the material during feeding. This method reduces the material feeding speed and also carries the risk of material getting stuck inside the discharge port and becoming difficult to feed.

[0005] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a feeding buffer device for a jaw crusher. Utility Model Content

[0006] The purpose of this invention is to provide a feeding buffer device for a jaw crusher to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a jaw crusher feeding buffer device, including a feeding plate, a supporting bracket provided on the lower surface of the feeding plate, and multiple guide grooves opened on both sides of the upper surface of the feeding plate. A connecting slider is slidably installed on the inner surface of the guide groove, and a supporting block is provided on the rear outer surface of the guide groove. A multi-stage reduction plate is provided on the upper surface of the connecting slider, and the multi-stage reduction plate is arc-shaped. A damping shock absorber is provided on the surface of the connecting slider, and the damping shock absorber is composed of a damper and a damping slide rod.

[0008] Preferably, the damping slide rod of the damping shock absorber is connected to the support block by a sliding through connection, and a limit plate is provided at the end of the damping shock absorber.

[0009] Preferably, the two sides of the feeding plate are provided with placement grooves, and the two outer sides of the feeding plate are provided with support frames.

[0010] Preferably, a support frame is slidably mounted on the inner surface of the placement groove, and a guide roller is rotatably mounted on the inner surface of the support frame.

[0011] Preferably, the rear surface of the support frame is provided with a connecting pad, and the rear surface of the connecting pad is provided with a limiting slide rod, and the limiting slide rod and the support frame are configured to slide through each other.

[0012] Preferably, the outer surface of the end of the limiting slide rod is provided with a threaded groove, and the outer surface of the limiting slide rod is provided with an adjusting spring.

[0013] Preferably, a rotating sleeve is spirally mounted on the outer surface of the threaded groove, and the rotating sleeve and the pressure adjusting spring are configured as a friction connection.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the arrangement of a feeding plate, supporting legs, guide chute, multi-stage speed reducer, connecting slider, damping shock absorber, support block, and limiting plate, achieves a deceleration effect by uniformly setting multiple arc-shaped multi-stage speed reducers on the upper surface of the feeding plate. When the material rolls along the arc-shaped surface of the multi-stage speed reducer during feeding in the jaw crusher, the gravitational component and the frictional force of the baffle surface will offset part of the kinetic energy, reducing the falling speed and avoiding impact damage to the subsequent conveyor belt caused by excessive material falling speed. The damping shock absorber buffers the impact of the material on the multi-stage speed reducer through frictional damping, protecting the multi-stage speed reducer while reducing the impact during material feeding.

[0016] 2. This utility model, through the arrangement of a placement groove, a support frame, a support bracket, a guide roller, a connecting pad, a limiting slide rod, a threaded groove, a rotating sleeve, and a pressure adjusting spring, uses the guide roller to guide the material during feeding through friction, preventing it from getting stuck inside the feeding plate due to friction and causing blockage that would affect the normal use of the feeding plate. The pressure adjusting spring, when the material contacts the guide roller with excessive impact during feeding, can release pressure by compressing the spring, allowing the support frame to slide along the placement groove to protect the guide roller.

[0022] 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.

[0023] like Figures 1-3 As shown, a jaw crusher feeding buffer device includes a feeding plate 1. The lower surface of the feeding plate 1 is provided with a support frame 101, and multiple guide grooves 102 are opened on both sides of the upper surface of the feeding plate 1. The advantage of this setting is that the feeding plate 1 can receive the material produced after the jaw crusher is crushed.

[0024] Furthermore, a connecting slider 201 is slidably mounted on the inner surface of the guide slide 102, and a support block 203 is provided on the rear outer surface of the guide slide 102. The advantage of this arrangement is that the sliding direction of the multi-stage deceleration plate 2 on the connecting slider 201 can be restricted by the guide slide 102 to prevent it from deviating during sliding pressure relief.

[0025] Furthermore, the upper surface of the connecting slider 201 is provided with multi-stage speed reduction plates 2, and the multi-stage speed reduction plates 2 are set in an arc shape. The advantage of this setting is that by uniformly setting multiple arc-shaped multi-stage speed reduction plates 2 on the upper surface of the feeding plate 1, when the material is fed into the jaw crusher, when the material rolls along the arc surface of the multi-stage speed reduction plates 2, the component of gravity and the friction force of the baffle surface will offset part of the kinetic energy, reduce the falling speed and achieve the effect of deceleration, and avoid the impact damage to the subsequent conveyor belt caused by the excessively fast falling speed of the material.

[0026] Furthermore, a damping shock absorber 202 is provided on the surface of the connecting slider 201, and the damping shock absorber 202 consists of a damper and a damping slide rod. The damping slide rod of the damping shock absorber 202 is connected to the support block 203 by a sliding through connection, and a limit plate 204 is provided at the end of the damping shock absorber 202. The advantage of this setting is that, by setting the damping shock absorber 202, the friction damping generated by the damping shock absorber 202 can buffer the impact of the material on the multi-stage deceleration plate 2 when the material is discharged, thus protecting the multi-stage deceleration plate 2 while reducing the impact when the material is discharged.

[0027] like Figure 4 As shown, the two sides of the feeding plate 1 are provided with placement grooves 3, and the two outer sides of the feeding plate 1 are provided with support frames 302. The inner surface of the placement groove 3 is slidably installed with a support frame 301, and the inner surface of the support frame 301 is rotatably installed with a guide roller 303. The advantage of this setting is that, through the setting of the guide roller 303, the material can be guided and fed by friction during feeding, so as to avoid it getting stuck inside the feeding plate 1 due to friction, causing blockage and affecting the normal use of the feeding plate 1.

[0028] Furthermore, a connecting pad 304 is provided on the rear surface of the support frame 301, and a limiting slide rod 305 is provided on the rear surface of the connecting pad 304. The limiting slide rod 305 and the support frame 302 are connected by a sliding through connection. The advantage of this setting is that the sliding direction of the support frame 301 can be restricted by the setting of the limiting slide rod 305.

[0029] Furthermore, the outer surface of the end of the limiting slide bar 305 is provided with a threaded groove 306, and the outer surface of the limiting slide bar 305 is provided with a pressure adjusting spring 308. The advantage of this setting is that, by setting the pressure adjusting spring 308, when the material contacts the guide roller 303 with excessive impact during material feeding, the pressure can be released by compressing the pressure adjusting spring 308 to allow the support frame 301 to slide along the placement groove 3 to protect the guide roller 303.

[0030] Furthermore, a rotating sleeve 307 is spirally mounted on the outer surface of the threaded groove 306, and the rotating sleeve 307 and the pressure regulating spring 308 are configured to be in frictional connection. The advantage of this configuration is that, by setting the rotating sleeve 307, the pressure threshold of the pressure regulating spring 308 can be adjusted by verifying the rotation of the threaded groove 306.

[0031] Working Principle: When using the jaw crusher feeding buffer device, firstly, after the jaw crusher has finished crushing the material and it needs to be transported, the material can be fed through the feeding plate 1. During feeding, the material will first contact the outer surface of the multi-stage reduction plate 2 for rolling friction, thereby reducing the speed and impact generated during the fall. The resulting impact will be damped by the frictional damping generated by the connecting slider 201 set on the lower surface of the multi-stage reduction plate 2 along the guide groove 102 to press against the damping shock absorber 202, thus achieving a deceleration buffering effect. For example, when the material is being fed... When the material comes into contact with the inner wall surface of the feeding plate 1, the guide roller 303 installed on its inner wall surface will rub against the surface of the material to reduce the frictional resistance between the material and the inner surface of the feeding plate 1, so that the material can be smoothly discharged from the feeding plate 1 and avoid blockage. If the impact on the guide roller 303 is too large, the guide roller 303 will drive the support frame 301 to slide and retract through the placement groove 3 to protect the guide roller 303. After the impact ends, the pressure regulating spring 308 will reset and drive the guide roller 303 to return to its original position for use. This is the working principle of the feeding buffer device of the jaw crusher.
