Description

Technical Field

[0001] The invention relates to the technical field of jaw crushers, and in particular to a device for quickly adjusting a discharge port of a jaw crusher. Background Art

[0002] A jaw crusher is a coarse crushing device widely used in the mining, building materials, metallurgy and other industries. Its working principle is to use an electric motor to drive the eccentric shaft to rotate and drive the movable jaw to perform periodic reciprocating motion. The material entering the crushing chamber is squeezed, split and bent between the two jaw plates, causing it to be crushed. It has the characteristics of simple structure, reliable operation, easy maintenance and high crushing ratio. It can process various ores and rocks with a compressive strength not exceeding 320 MPa. Typical models include PE series and PEX series. The discharge particle size can be controlled by adjusting the size of the discharge port. It is usually used in the first crushing process of the production line to provide a suitable feed particle size for subsequent secondary and fine crushing equipment.

[0003] The Chinese patent application number CN106179570B discloses a jaw crusher and a method for adjusting a discharge opening. The jaw crusher includes a frame, a fixed jaw plate, and a movable jaw plate. The fixed jaw plate is fixed to the frame, and the movable jaw plate is movably arranged relative to the fixed jaw plate. The lower end of the fixed jaw plate and the lower end of the movable jaw plate form a discharge opening. The jaw crusher also includes an automatic discharge opening adjustment system. The automatic discharge opening adjustment system includes a controller and an actuator. The actuator is driven and connected to the movable jaw plate. The controller and the actuator are coupled to automatically control the actuator to drive the movable jaw plate to move according to a set value to adjust the distance between the lower end of the fixed jaw plate and the lower end of the movable jaw plate to adjust the size of the discharge opening. The jaw crusher of the present invention can automatically adjust the size of the discharge opening through the controller when the fixed jaw plate or the movable jaw plate becomes larger due to wear, without the need for manual periodic adjustment, thereby improving the adjustment efficiency of the discharge opening.

[0004] The existing jaw crusher consists of a pair of movable and stationary jaw plates. The movable jaw plate continuously squeezes against the stationary jaw plate, crushing the stone. However, the relatively fixed mounting positions of the movable and stationary jaw plates result in a fixed size discharge port for the finished material, making it difficult to adjust the discharge volume. Therefore, improvements are needed. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a device for quickly adjusting the discharge port of a jaw crusher.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A device for quickly adjusting a jaw crusher discharge port comprises a chassis plate and:

[0008] The quick adjustment component includes an arc-shaped groove opened on one side of the chassis plate, a first rotating shaft is installed inside the arc-shaped groove, one end of the first rotating shaft is provided with an external thread, a screw cover is screwed and installed on the surface of the external thread, and a handle is provided on one side of the first rotating shaft.

[0009] According to a further technical solution, the arc-shaped groove is an upward-rising slot hole structure, and the screw cover is screwed onto the surface of the arc-shaped groove when in the installed state.

[0010] Further technical solutions also include:

[0011] The driving end assembly includes a movable jaw crushing plate, a second steel ring is fixedly installed on one side of the movable jaw crushing plate, a cam is eccentrically installed inside the second steel ring, a baffle is provided on one side of the second steel ring, and a second rotating shaft is provided on one side of the cam.

[0012] Further technical solutions also include:

[0013] The movable end assembly includes a first steel ring fixedly installed on one side of the movable jaw crusher, and the movable end assembly also includes a slide cylinder installed in an array around the first rotating shaft. The internal connection of the slide cylinder is installed with a spring, and one side of the spring is connected to a slide rod, which is slidably installed inside the slide cylinder, and a pad is provided at the end of the slide rod. The pad support is installed inside the first steel ring, and a limit plate is provided on one side of the first rotating shaft, and the limit plate covers the surface of the first steel ring.

[0014] Further technical solutions also include:

[0015] The drive assembly includes a first pulley docked and installed on one side of the first rotating shaft, a second pulley is provided on the other side of the first pulley, a belt is installed around the first pulley and the second pulley, and a motor is installed on one side of the second pulley for transmission.

[0016] Further technical solutions also include:

[0017] The fixed end assembly includes a positioning plate fixedly mounted on the inner side of the chassis plate, and a static jaw plate is slidably mounted on one side of the positioning plate.

[0018] Further technical solutions also include:

[0019] Direct drive assembly, the direct drive assembly includes a slider fixedly installed on one side of the static jaw crusher plate, the internal transmission of the slider is installed with a screw, one side of the screw is transmission-installed with a rotor, the other side of the screw is provided with a bearing, one side of the bearing is provided with a bearing seat, both sides of the bearing seat are provided with bolts, and the bolts are fixedly installed on the inner side of the chassis plate.

[0020] A further technical solution also includes: a lining plate is provided on one side of the first rotating shaft and the second rotating shaft close to the inner side of the chassis plate, and reinforcing ribs are evenly provided on the outer facade of the chassis plate.

[0021] Compared with the prior art, the present invention provides a device for quickly adjusting the discharge opening of a jaw crusher, which has the following beneficial effects:

[0022] The present invention utilizes a quick-adjustment assembly to modify the mounting position of one side of the movable jaw crusher in the prior art. An arcuate slot is provided on the chassis plate mounted on the movable end to adjust the position of the first rotating shaft. To adjust the position of the first rotating shaft and thereby adjust the discharge diameter, the handle moves the first rotating shaft within the arcuate slot. After adjustment, the screw cap is tightened onto the external thread on one side of the first rotating shaft. This allows for quick and convenient operation by directly changing the position of the first rotating shaft to adjust the discharge diameter.

[0023] The present invention modifies the movable jaw plate to prevent direct contact between the first rotating shaft and the oscillating first steel ring. Instead, a sliding rod is slidably mounted around the first rotating shaft via a sliding tube, and a spring is connected between the sliding tube and the rod to provide a cushioning effect. A pad at the end of the sliding rod supports the interior of the first steel ring, providing a cushioning effect when the first steel ring oscillates within a certain range, while also increasing the oscillation space of the first steel ring.

[0024] The present invention also modifies the drive end of the movable jaw crusher, using an eccentrically mounted cam. Driven by a pulley, belt, or other device, the cam rotates and acts eccentrically on the interior of the second steel ring, causing it to swing, thereby achieving the interlocking crushing effect of the movable jaw crusher. Because the cam can be made larger in diameter, it offers enhanced shear resistance and a longer service life.

[0025] This invention also modifies one end of the originally fixed static jaw plate, mounting it on the surface of the screw via a slider at the bottom. Driven by the screw, motor, and bearing block, the static jaw plate achieves linear motion in the crushing direction, enabling direct adjustment of the discharge port diameter. Combined with the aforementioned adjustment method for the movable jaw plate, rapid adjustment of the discharge port diameter is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Working principle:

[0049] In the actual design process, in order to avoid the following defects existing in the prior art: "In the prior art, the main structure of the jaw crusher is a pair of movable jaw plates and static jaw plates. The movable jaw plate continuously performs an extrusion movement on the surface of the static jaw plate to achieve the effect of extruding and crushing stones. However, the installation positions of the movable jaw plate and the static jaw plate are relatively fixed, which makes the size of the discharge port of the finished material fixed, making it difficult to adjust the discharge volume of the discharge port, and therefore needs to be improved.", the present invention specifically proposes a movable end assembly 3, a quick adjustment assembly 4, a driving end assembly 5, a driving assembly 6, a fixed end assembly 7 and a direct drive assembly 8;

[0050] Active end component 3:

[0051] The movable end assembly 3 is a structure arranged above the movable jaw plate 9 and cooperates with the upper drive end assembly 5 to realize the movement of the jaw crusher. Since the movable jaw plate 9 transfers part of the kinetic energy to this assembly under the action of the drive end assembly 5, this assembly needs to have a certain shaking effect to cooperate with the movement. The first steel ring 10 is fixed on one side of the movable jaw plate 9 as the basis for the transmission of the first rotating shaft 11; the sliding rod 14 is slidably installed on the periphery of the first rotating shaft 11 through the slide 12, and the spring 13 is connected and installed between the slide 12 and the slide rod 14 to realize the sliding buffering of the slide rod 14 inside the slide 12. The pad 15 arranged at the end of the slide rod 14 is supported on the radial part of the first rotating shaft 11, and cooperates with the first steel ring 10 to achieve the effect of shaking and buffering. The transmission torque is increased by adopting the method of the first rotating shaft 11 with the first steel ring 10 built in to transmit the power, which can avoid the problem of easy damage to this part in the prior art.

[0052] Quick adjustment component 4:

[0053] The position corresponding to the movable end assembly 3 is the material discharge port. Therefore, this solution uses adjustment of this position to quickly adjust the discharge port diameter. An arcuate slot 17 is provided on the side of the chassis plate 1 corresponding to the first rotating shaft 11; the position of the first rotating shaft 11 within the arcuate slot 17 can be adjusted to adjust the discharge port diameter. After adjustment, simply tighten the screw cap 19 onto the external thread 18 to secure the port. This assembly allows for quick adjustment of the discharge port diameter.

[0054] Drive end component 5:

[0055] The drive-end assembly 5 is the input point for the dynamic jaw crushing plate 9's power. It includes a second steel ring 21 fixedly mounted on one side of the dynamic jaw crushing plate 9. The eccentrically mounted hammer 22 inside the second steel ring 21 drives the dynamic jaw crushing plate 9 on the second steel ring 21 to engage during rotation, thereby achieving the jaw crushing effect. To prevent the hammer 22 from falling off, this solution also provides a baffle 23 on one side of the second steel ring 21 for position limiting.

[0056] Drive component 6:

[0057] The driving assembly 6 is a component that transmits the above-mentioned driving end assembly 5, including a power source - a motor 28; a transmission structure - a first pulley 25, a second pulley 26 and a belt; the second pulley 26 outputs power to the cam 22 through the second rotating shaft 24 to achieve the rotation effect of the cam 22.

[0058] Fixed end assembly 7 and direct drive assembly 8;

[0059] The fixed end assembly 7 is the static jaw plate in the prior art, and its main structure is the static jaw plate 29 placed on one side of the movable jaw plate 9. In order to make use of the static jaw plate 29, the discharge diameter can be adjusted. In this solution, a slider 30 is fixedly installed on one side of the static jaw plate 29. The slider 30 can move left and right on the surface of the screw rod 31 under the transmission action of the rotor 32. During the movement, the discharge diameter is reduced and expanded respectively, which is also a way to achieve rapid adjustment. In order to limit the position of the screw rod 31, this solution sets a bearing seat 33 on one side of the screw rod 31, and a bearing 34 is installed inside the bearing seat 33 and supported on the surface of the screw rod 31; the bearing 34 can ensure the stable operation of the screw rod 31.
