Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically to an impact plate adjustment device and an impact crusher. Background Technology

[0002] Impact crushers crush materials through impact plates. The position of the impact plates needs to be calibrated to meet the production requirements of different particle sizes and to compensate for errors caused by wear. In addition, the stroke of the impact plates needs to be limited to provide safety protection when the impact plates are out of control.

[0003] Some related technologies use nuts and springs to position the impact plate, and the stroke range of the impact plate can be manually adjusted by turning the nut. However, the operating environment of impact crushers is generally harsh, the threaded parts are easily contaminated, and a measuring ruler is required when calibrating the position, which is time-consuming and laborious, and not conducive to on-site operation and maintenance. Utility Model Content

[0004] In view of this, the present invention provides an impact plate adjustment device and an impact crusher to solve the problem of time-consuming and labor-intensive position adjustment.

[0005] In a first aspect, this utility model provides a counter-attack plate adjustment device, including a hydraulic cylinder, a first limiting member, a second limiting member, and a driving member. The hydraulic cylinder includes a cylinder body and a piston rod. The piston rod is disposed on the cylinder body and is movable in a first direction. The first limiting member is disposed on the piston rod. The second limiting member is opposite to the first limiting member in the first direction and is located on the side of the first limiting member away from the cylinder body. The driving member is disposed on the cylinder body and is throttle-connected to the second limiting member. The driving member is capable of driving the second limiting member to move in the first direction.

[0006] Beneficial effects: On the one hand, the piston rod is used to connect the impact plate, and the impact plate is moved electrically by the hydraulic cylinder, which makes it easy and accurate to mark the position of the impact plate without manual adjustment; on the other hand, the first and second limiting members can contact each other when the impact plate is out of control, thereby limiting the extreme position of the impact plate. The position of the second limiting member can also be electrically marked by the driving component without manual adjustment. Therefore, the impact plate adjustment device helps to simplify the calibration process and makes the adjustment of the impact plate more convenient; in addition, the integration of the first limiting member, the second limiting member, and the driving component on the hydraulic cylinder improves the modularity of the impact plate adjustment device, which is beneficial to the disassembly, assembly, and maintenance of the impact plate adjustment device.

[0007] In an alternative embodiment, a lead screw mechanism is further included, through which the drive member is connected to the second limiting member.

[0008] Beneficial effects: Using a lead screw mechanism for transmission can improve the positioning accuracy of the second limiting component, and the lead screw mechanism has a self-locking characteristic, thereby improving the positional stability of the second limiting component during impact.

[0009] In one optional embodiment, the lead screw mechanism includes a guide rod and a slider, the guide rod extending in the first direction, the second limiting member disposed on the guide rod, the slider and the guide rod being threadedly connected, and the driving member being capable of driving the slider to rotate.

[0010] Beneficial effects: By using the slider as the driving component and the guide rod as the driven component, the connection between the slider and the guide rod is kept away from the impact plate, reducing the risk of contamination of the threaded pair of the screw mechanism and improving the reliability of the impact plate adjustment device.

[0011] In one optional embodiment, the counter-attack plate adjustment device includes a plurality of the aforementioned lead screw mechanisms, and the driving element and each of the aforementioned sliders are respectively connected by a gear mechanism.

[0012] Beneficial effects: Multiple guide rods are connected to different parts of the second limiting member, providing multi-point support and positioning, thus improving the positional accuracy of the second limiting member. The drive component is connected to the slider through a gear mechanism, which ensures that the rotation of each slider remains synchronized, making the movement of the second limiting member smoother.

[0013] In an alternative embodiment, a support plate is further included, the support plate being disposed at one end of the cylinder body away from the piston rod, and the slider being rotatably disposed on the support plate.

[0014] Beneficial effects: The bracket plate provides more installation space for the slider. Placing the bracket plate at the end away from the piston rod helps to move the slider further away from the piston rod, reducing the risk of contamination of the threaded pair of the screw mechanism.

[0015] In one alternative embodiment, a guide seat is further included, the guide seat being disposed on the cylinder body, and the guide rod passing through the guide seat.

[0016] Beneficial effects: The guide seat can play a positioning and guiding role, ensuring that the guide rod moves accurately along the first direction.

[0017] In one optional embodiment, the second limiting member is sleeved on the guide rod, and the counter-attack plate adjustment device further includes a plurality of locking nuts, which are disposed on the guide rod for locking the second limiting member.

[0018] Beneficial effects: The second limiting component is detachably connected to the guide rod, which facilitates the replacement of the second limiting component. The second limiting component is locked by a lock nut, which can improve the impact resistance of the second limiting component and prevent the second limiting component from shifting its position under impact.

[0019] In one alternative embodiment, the second limiting member is sleeved on the piston rod, and the first limiting member is circumferentially disposed around the outer periphery of the piston rod.

[0020] Beneficial effects: The first limiting member is arranged around the outer circumference of the piston rod, thereby making the first limiting member and the first limiting member in uniform contact in the circumferential direction, improving the uniformity of the force on the first limiting member.

[0021] In one alternative embodiment, a first connecting portion and a second connecting portion are further included. The first connecting portion is disposed on the cylinder body for hinged connection of the frame, and the second connecting portion is disposed at the end of the piston rod away from the cylinder body for hinged connection of the counterattack plate.

[0022] Beneficial effects: The impact plate adjustment device is hinged to the frame and the impact plate, which allows for flexible adjustment of the installation angle to meet the connection requirements of different usage scenarios.

[0023] Secondly, this utility model also provides an impact crusher, including a rotor, an impact plate, and an impact plate adjustment device provided by this utility model. The impact plate is located on one side of the rotor, and the impact plate adjustment device is connected to the impact plate.

[0024] Beneficial effects: The impact crusher includes the impact plate adjustment device provided by this utility model, and therefore has the corresponding beneficial effects brought by the impact plate adjustment device, which will not be elaborated here. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, 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.

[0037] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a," "an," and "comprising" as used herein may also mean including the plural forms. The terms "comprising," "including," and "having" are inclusive and therefore indicate the presence of the stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0038] Although terms such as "first," "second," etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Furthermore, in the description of this utility model, unless otherwise expressly specified and limited, the terms "set up" and "connected" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "end," "length," "inner," "outer," etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation, in addition to those depicted in the figure. For example, if the mechanism in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The mechanism may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0040] Impact crushers crush materials by rebounding them through impact plates and a rotor. The position of the impact plates needs to be calibrated to meet the production requirements of different particle sizes.

[0041] In related technologies, the impact plate is mounted on a guide rod, and a spring pushes the impact plate against a nut to position it. The impact plate is calibrated by rotating the nut. However, the nut is located on the side of the impact plate where the material rebounds, making the threaded joint susceptible to contamination. Furthermore, calibration requires the use of a measuring ruler, resulting in time-consuming and labor-intensive adjustments. Additionally, the stroke of the impact plate is only constrained by the nut, lacking further safety protection in case of loss of control.

[0042] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.

[0043] Reference Figure 1 , Figure 2According to an embodiment of the present invention, a counter-attack plate adjustment device is provided, comprising a hydraulic cylinder, a first limiting member 201, a second limiting member 202, and a driving member 301. The hydraulic cylinder includes a cylinder body 101 and a piston rod 102, the piston rod 102 being disposed on the cylinder body 101 and capable of adjusting the piston rod in a first direction (in... Figure 1 (shown in the X direction) The piston rod 102 moves upward. The first limiting member 201 is disposed on the piston rod 102. The second limiting member 202 is opposite to the first limiting member 201 in the first direction and is located on the side of the first limiting member 201 away from the cylinder body 101. The driving member 301 is disposed on the cylinder body 101 and is connected to the second limiting member 202. The driving member 301 can drive the second limiting member 202 to move in the first direction.

[0044] Piston rod 102 is used to connect the counter-attack plate. Figures 3 to 8 One calibration procedure for a counter-attack plate adjustment device is illustrated by way of example.

[0045] Reference Figure 3 The piston rod 102 is initially in a random position. Through the action of the cylinder 101, the piston rod 102 is moved to... Figure 4 The starting position is shown (at this point, the size of the hydraulic chamber on one side of cylinder 101 is defined as L1); then, based on this state, the piston rod 102 is pushed out until the counter-attack plate contacts the rotor, reaching... Figure 5 The zero-point position is shown (at this time, the size of the hydraulic chamber on one side of cylinder 101 is defined as L0); according to the set safety distance L s This causes the piston rod 102 to retract, reaching... Figure 6 The safety protection position is shown; the second limiting member 202 is moved by the driving member 301 until it contacts the first limiting member 201 (e.g., Figure 7 (As shown), thus completing the position calibration of the second limit member 202; according to the set working distance L s’ This causes the piston rod 102 to retract, reaching... Figure 8 The working position is shown, thus completing the calibration of the piston rod 102.

[0046] On the one hand, the hydraulic cylinder is used to electrically drive the counterattack plate to move, which makes it easy and accurate to mark the position of the counterattack plate without manual adjustment. On the other hand, the first limiting member 201 and the second limiting member 202 can contact each other when the counterattack plate is out of control, thereby limiting the extreme position of the counterattack plate. The position of the second limiting member 202 can also be electrically marked by the driving member 301 without manual adjustment. Therefore, the counterattack plate adjustment device helps to simplify the calibration process and makes the adjustment of the counterattack plate more convenient.

[0047] Furthermore, the first limiting member 201, the second limiting member 202, and the driving member 301 are integrated on the hydraulic cylinder, improving the modularity of the counterattack plate adjustment device and facilitating its disassembly, assembly, and maintenance. Since the counterattack plate's runaway protection is achieved through the first limiting member 201 and the second limiting member 202, conventional hydraulic cylinders (such as double-acting hydraulic cylinders) can be used, eliminating the need for a three-cylinder hydraulic cylinder. This also reduces the cost of the counterattack plate adjustment device and improves the reliability of the runaway protection.

[0048] Optionally, refer to Figure 1 and Figure 2 In some embodiments, the impact plate adjustment device further includes a lead screw mechanism, through which the drive member 301 is connected to the second limiting member 202. Using a lead screw mechanism for transmission improves the positioning accuracy of the second limiting member 202, and the lead screw mechanism has a self-locking characteristic, thereby improving the positional stability of the second limiting member 202 during impact.

[0049] It is understood that the lead screw mechanism includes a threaded guide rod 302 and a slider 303, one of which acts as the driving member and is connected to the driving member 301, while the other acts as the driven member and is connected to the second limiting member 202. Exemplarily, in some embodiments, the guide rod 302 extends in a first direction, the second limiting member 202 is disposed on the guide rod 302, the slider 303 is threadedly connected to the guide rod 302, and the driving member 301 can drive the slider 303 to rotate.

[0050] At this time, the driving component 301 can be a rotary motor, the slider 303 is the driving component, and the guide rod 302 is the driven component. The driving component 301 drives the slider 303 to rotate, and the slider 303 drives the guide rod 302 to move in the first direction, thereby realizing the position adjustment of the second limiting component 202 in the first direction. This design keeps the connection part of the slider 303 and the guide rod 302 away from the impact plate, reduces the risk of contamination of the thread pair of the screw mechanism, and improves the reliability of the impact plate adjustment device.

[0051] Of course, in addition to the lead screw mechanism, the drive component 301 can also drive the second limit component 202 to move in other ways, such as through a gear and rack mechanism, etc. Other feasible drive methods can be referred to the relevant existing technologies, which will not be elaborated here.

[0052] Continue to refer to Figure 1 and Figure 2In some embodiments, the counter-attack plate adjustment device includes multiple lead screw mechanisms, and the drive member 301 and each slider 303 are respectively connected by gear mechanisms. Multiple guide rods 302 are respectively connected to different parts of the second limiting member 202, providing multi-point support and positioning, improving the positional accuracy of the second limiting member 202. The drive member 301 is connected to the sliders 303 through gear mechanisms, ensuring that the rotation of each slider 303 remains synchronized, making the movement of the second limiting member 202 smoother. By adjusting the transmission ratio of the gear mechanism, the rotational speed can also be amplified or reduced.

[0053] For example, the gear mechanism may include a first gear 304 and a second gear 305. The first gear 304 is disposed on the output shaft of the drive member 301, and the second gear 305 is disposed on the slider 303. The first gear 304 and the second gear 305 mesh, so that the drive member 301 can drive multiple sliders 303 to rotate synchronously.

[0054] In some embodiments, the counter-attack plate adjustment device further includes a support plate 401, which is disposed at the end of the cylinder 101 away from the piston rod 102, and the slider 303 is rotatably disposed on the support plate 401. The support plate 401 provides more installation space for the slider 303, and placing the support plate 401 at the end away from the piston rod 102 helps to further move the slider 303 away from the piston rod 102, reducing the risk of contamination of the threaded pair of the lead screw mechanism.

[0055] For example, refer to Figure 2 The drive unit 301 can also be set on the bracket plate 401.

[0056] In some embodiments, the counter-attack plate adjustment device further includes a guide seat 402, which is disposed on the cylinder body 101, and the guide rod 302 passes through the guide seat 402. The guide seat 402 can play a positioning and guiding role, ensuring that the guide rod 302 moves accurately along the first direction.

[0057] For example, refer to Figure 2 The counter-attack plate adjustment device has multiple guide seats 402 ( Figure 2 In the illustrated embodiment, there are two guide seats 402 arranged at intervals in the first direction. The guide rod 302 passes through multiple guide seats 402 simultaneously, which helps to better constrain the degree of freedom of the guide rod 302 and avoid bending and deformation of the guide rod 302.

[0058] In some embodiments, the second limiting member 202 is sleeved on the guide rod 302, and the counter-attack plate adjustment device further includes a plurality of locking nuts 306, which are disposed on the guide rod 302 for locking the second limiting member 202.

[0059] The second limiting member 202 is detachably connected to the guide rod 302, which facilitates the replacement of the second limiting member 202. The second limiting member 202 is locked by the locking nut 306, which can improve the impact resistance of the second limiting member 202 and prevent the second limiting member 202 from shifting its position under impact.

[0060] For example, refer to Figure 2 The two sides of the second limiting member 202 are locked by two locking nuts 306 respectively. The two locking nuts 306 are superimposed on each other, which helps to improve the vibration resistance of the locking nuts 306 and further reduces the risk of the second limiting member 202 shifting position under impact.

[0061] In some embodiments, the second limiting member 202 is sleeved on the piston rod 102, and the first limiting member 201 is circumferentially disposed around the outer periphery of the piston rod 102. The first limiting member 201 circumferentially disposed around the outer periphery of the piston rod 102 ensures uniform contact between the first limiting member 201 and the piston rod 102 in the circumferential direction, improving the uniformity of force on the first limiting member 201 and preventing excessive torque caused by uneven force distribution, which could lead to piston rod 102 failure.

[0062] In some embodiments, the impact plate adjustment device further includes a first connecting portion 103 and a second connecting portion 104. The first connecting portion 103 is disposed on the cylinder body 101 and is used for hinged connection to the frame. The second connecting portion 104 is disposed at the end of the piston rod 102 away from the cylinder body 101 and is used for hinged connection to the impact plate. The impact plate adjustment device is hinged to the frame and the impact plate, thereby enabling flexible adjustment of the installation angle to meet the connection requirements of different usage scenarios.

[0063] Secondly, this utility model also provides an impact crusher, including a rotor, an impact plate, and an impact plate adjustment device provided by this utility model. The impact plate is located on one side of the rotor, and the impact plate adjustment device is connected to the impact plate.

[0064] The impact crusher includes the impact plate adjustment device provided by this utility model, and therefore has the beneficial effects brought by the impact plate adjustment device, which will not be described in detail here.

[0065] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
