Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to an easy-to-maintain impact crusher. Background Technology

[0002] Crusher, including impact crushers, is used in material crushing operations in the mining and building materials industries. Impact crushers are widely used due to their high crushing efficiency and uniform product particle size. However, under long-term high-intensity operation, the need for replacement of wear parts and maintenance of the transmission system is frequent. However, existing impact crushers still have the following shortcomings in maintenance: The maintenance housing of the crushing chamber is usually fixed by multiple sets of bolts. Disassembly requires the use of a wrench to disassemble them one by one, which makes the disassembly and assembly of the maintenance housing and the transmission belt complicated and increases labor costs, seriously affecting the progress of maintenance inside the crushing chamber and the transmission belt. The friction points of the rotating shaft in the crushing chamber are prone to high temperatures when rotating for a long time, which can easily damage the friction points of the rotating shaft. If the high-temperature rotating shaft continues to operate, it can easily damage the entire drive mechanism.

[0003] In summary, existing impact crushers suffer from low maintenance efficiency, inconvenient adjustment, and insufficient protection. There is an urgent need to design an easy-to-maintain impact crusher that is convenient to disassemble and assemble, highly efficient to maintain, and has strong stability. Utility Model Content

[0022] 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, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1 to 9 : This utility model proposes an easy-to-maintain impact crusher, including: a base 1, a crushing body 2 installed on the upper end of the base 1, the crushing body 2 including a maintenance shell, the maintenance shell installed on the upper end of the crushing body 2, a set of mounting holes respectively opened on the upper end of the crushing body 2 and the bottom of the maintenance shell, a set of locking pins 201 installed inside the mounting holes, after the locking pins 201 are installed, the maintenance shell is positioned on the upper end of the crushing body 2, completing the initial positioning of the maintenance shell. In this embodiment, a set of connecting plates 3 are installed on the upper side of the crushing body 2. The side of the connecting plates 3 is in slight contact with the outer wall of the crushing body 2. The outer wall of the crushing body 2 is circumferentially positioned against the connecting plates 3. A set of evenly distributed locking plates 301 are provided on one side of the connecting plates 3. The locking plates 301 have a U-shaped structure and are aligned with the locking pins 201. An annular groove is formed on the periphery of the locking pins 201, and the interior of the locking plates 301 extends into the interior of the annular groove. The connecting plates 3, in conjunction with the locking plates 301, quickly lock the set of locking pins 201, thereby quickly and firmly securing the maintenance housing to the upper end of the crushing body 2, improving the installation efficiency of the maintenance housing. Pushing the connecting plates 3 to one side moves the locking plates 301, causing the locking plates 301 to move away from the locking pins 201. At this point, the maintenance housing is unlocked, simplifying the disassembly process of the maintenance housing and facilitating subsequent maintenance of the crushing body. Main body 2; In addition, the U-shaped structure of the locking plate 301 provides sufficient swing space, so that when the connecting plate 3 and the locking plate 301 are displaced by vibration, the locking plate 301 is always connected to the locking pin 201; A sliding hole is opened on one side of the connecting plate 3, and a positioning bolt 302 is installed through the sliding hole. A set of threaded holes aligned with the sliding hole are opened at the upper end of the crushing main body 2. One side of the positioning bolt 302 is threadedly connected to the threaded hole. The thread pitch is processed according to actual needs so that the threaded hole can stably lock the positioning bolt 302. After the positioning bolt 302 is installed, it positions the connecting plate 3 vertically. A support spring is installed on the outer side of the positioning bolt 302. The elastic force of the support spring is selected according to actual needs so that the support spring can stably push the locking plate 301 to fit against the locking pin 201, ensuring that the locking plate 301 stably locks the locking pin 201. In this embodiment, a temperature sensor 4 is installed at the bottom of one side of the crushing body 2. A threaded connecting sleeve is provided at the upper end of the stabilizing cover 202. The threaded connecting sleeve and the stabilizing cover 202 are connected. The bottom of the temperature sensor 4 passes through the inside of the threaded connecting sleeve. The threaded connecting sleeve stabilizes the installation position of the temperature sensor 4, so that the temperature sensor 4 and the stabilizing cover 202 are stably connected. The temperature sensor 4 detects the temperature inside the stabilizing cover 202. Since the stabilizing cover 202 is located outside the rotating shaft of the crushing body 2, the heat of the rotating shaft can be transferred to the inside of the stabilizing cover 202 at the same time. The temperature sensor 4 is electrically connected to an external controller. The temperature sensor 4 monitors the operating temperature of the rotating shaft in real time and issues an early warning when there is an abnormality. A motor 5 is mounted on one side of the upper end of the base 1. A rotating shaft extends outward from the bottom of the crushing body 2. A pulley is mounted on the outer side of both the rotating shaft and the drive shaft of the motor 5. A belt is installed between the two pulleys. A stabilizing cover 202 is installed on the outer side of the rotating shaft. Bearings can be installed inside the stabilizing cover 202 according to conventional procedures. The stabilizing cover 202 protects and reinforces the rotating shaft and bearings. A rotatably connected threaded rod 601 is mounted on the side of the base 1. A sliding block 602 is mounted on the outer side of the threaded rod 601. A sliding groove with a T-shaped structure is opened at the corner of the base 1. The sliding groove and the sliding block 602 correspond to each other. The sliding block 602 extends into the interior of the sliding groove. A set of bolt mounting holes is made at the corner and the bottom of motor 5. Matching bolts are installed inside the bolt mounting holes as needed, completing the secure connection between motor 5 and sliding block 602. The sliding groove restricts the rotation and offset of sliding block 602, allowing it to move stably laterally along the sliding groove. This facilitates adjusting the position of motor 5 by moving sliding block 602. A threaded hole is made in the middle of sliding block 602, corresponding to a threaded rod 601. The threaded rod 601 passes through the inside of the threaded hole. The thread pitch is machined according to actual needs, ensuring precise threaded connection between sliding block 602 and threaded rod 601. Rotating threaded rod 601 causes sliding block 602 to move linearly, allowing the sliding block to move smoothly. The moving block 602 drives the motor 5 to move, thereby adjusting the belt tension through the movement of the motor 5, and at the same time achieving the effect of easy belt disassembly and assembly; a stepped smooth rod is provided on one side of the threaded rod 601, and a rotating hole is opened on one side of the base 1. The smooth rod of the threaded rod 601 passes through the interior of the rotating hole. The stepped smooth rod positions the rotation of the threaded rod 601, so that the threaded rod 601 can rotate stably in place. A handwheel is installed on one side of the threaded rod 601, and a positioning gear 603 is installed on one side of the threaded rod 601 near the handwheel. The positioning gear 603 is firmly engaged with the threaded rod 601 by using the friction surface. The threaded rod 601, the sliding block 602, and the positioning gear 603 cooperate with each other to form the adjustment mechanism 6; In this embodiment, an ear plate 101 is provided on the side of the base 1. A locking rod 7 is installed through the ear plate 101. A set of rectangular teeth is provided on the periphery of the positioning gear 603. A locking groove corresponding to the positioning gear 603 is opened on one side of the locking rod 7. The rectangular teeth of the positioning gear 603 extend into the interior of the locking groove. A retaining ring is provided on the outer side of the locking rod 7. A support spring is installed on the outer side of the locking rod 7. The support spring is located between the retaining ring and the ear plate 101. The elastic force of the support spring is selected according to actual needs so that the support spring can stably push the locking rod 7 to a position closer to the positioning gear 603 for reset. Specifically, the locking rod 7 engages with the locking groove to achieve angle locking of the threaded rod 601. To prevent the threaded rod 601 from rotating in the opposite direction after adjustment, a control frame 701 is installed on one side of the locking rod 7. One side of the control frame 701 is inserted into the mounting hole. The friction of the mounting surface is used to stably engage the locking rod 7 and the control frame 701. A set of positioning grooves is opened on the inner side of the control frame 701. The positioning grooves are U-shaped and correspond to the ear plate 101. One side of the ear plate 101 extends into the interior of the positioning groove. With the cooperation of the ear plate 101 and the positioning groove, the control frame 701 achieves the effect of circumferential positioning, thereby enabling the control frame 701 to circumferentially position the locking rod 7 and ensure that the locking rod 7 effectively and accurately meshes with the positioning gear 603. At the same time, the control frame 701 facilitates manual pulling to unlock the locking rod 7.

[0024] Example 2, based on Example 1, such as Figures 1-7 As shown, the temperature sensor 4 is selected according to the actual needs and is a commonly used model for bearing temperature detection. The temperature sensor 4 is electrically connected to the alarm according to the conventional procedure. The crushing body 2 is a conventional impact crusher model.

[0025] The working principle of this embodiment: First, the motor 5 drives the rotating shaft of the crushing body 2 to rotate via a belt. After the material enters the crushing chamber of the crushing body 2, it is crushed under the impact of the hammer and the impact plate. The temperature sensor 4 monitors the temperature around the rotating shaft in real time and is linked with the external controller and alarm. When the temperature is abnormal, it issues an early warning in time to avoid the bearing from overheating and burning out. When it is necessary to maintain the internal components of the crusher body 2, push the connecting plate 3 to one side to drive the locking plate 301 to disengage from the annular groove of the locking pin 201, and then unlock the maintenance housing; after opening the maintenance housing, the hammer plate and the impact plate can be quickly replaced and repaired. After maintenance is completed, the maintenance housing is initially positioned by the locking pin 201, and then the connecting plate 3 is released. The support spring pushes the locking plate 301 into the annular groove of the locking pin 201, thus completing the locking of the locking pin 201 and the maintenance housing. When adjusting or removing the belt tension, first pull the control frame 701 outward to move the locking lever 7 outward, so that the locking lever 7 is away from the positioning gear 603, and unlock the threaded rod 601; turn the handwheel to drive the threaded rod 601 to rotate, thereby moving the sliding block 602 laterally, and thus adjusting the position of the motor 5 to achieve belt tension adjustment; after adjustment, release the control frame 701, and the support spring pushes the locking lever 7 to reset and lock the threaded rod 601 again.
