Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically a high-energy jaw crusher. Background Technology

[0002] A jaw crusher is a common type of crushing equipment, also known as a jaw crusher or jaw breaker. It is a mechanical device used to crush hard materials into smaller particles. A jaw crusher mainly consists of a fixed jaw plate and a movable jaw plate. During operation, the movable jaw plate applies pressure and friction to the material, crushing it into the desired size.

[0003] For example, the announcement number CN210729627U is a biomass straw screw feeder. The device includes a box body. This utility model improves the processing quality of the crusher by setting up a filter screen, a filter shell, connecting threads, crushing fan blades, a second rotating shaft, a second motor and bearings, so that unqualified stones after crushing can be blocked by the filter screen and processed again by the crushing fan blades.

[0004] When the above-mentioned device crushes materials, because dust removal facilities are not installed at key locations such as the feed inlet of the box, the dust generated during the crushing process will be discharged directly from the feed inlet due to the vibration of the box. This not only causes environmental pollution, but also has an adverse effect on the health of operators if they are exposed to such a working environment for a long time. Therefore, we propose a high-energy jaw crusher to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a high-energy jaw crusher to solve the problem mentioned in the background art that when existing jaw crushers crush materials, dust generated during the crushing process is directly discharged from the feed inlet due to the lack of dust removal facilities installed at key locations such as the feed inlet of the crusher. This not only causes environmental pollution, but also has an adverse effect on the health of operators if they are exposed to such a working environment for a long time.

[0007] Preferably, a mounting plate is installed at one end of the housing, a drive motor is installed on the upper part of the mounting plate, the drive motor is fixedly connected to the mounting plate through a mounting base, a drive wheel is installed on the output shaft of the drive motor, and the drive wheel is connected to the driven wheel at the same end through a belt drive.

[0008] Preferably, an elbow seat is installed on the bottom of the housing near the movable jaw plate, and an elbow plate is rotatably connected between the elbow seat and the movable jaw plate. Fixing rods are installed inside both sides of the elbow plate, and fixing blocks are installed at both ends of the side of the movable jaw plate opposite to the elbow seat. The two ends of the fixing rods are connected to the fixing blocks, and bearings are installed at the connection between the fixing rods and the fixing blocks.

[0009] Preferably, the lower part of the elbow seat is provided with a built-in groove, and a circular hole is provided on the side of the built-in groove near the moving jaw plate. A pull rod is slidably connected inside the circular hole. The pull rod is installed at an angle, and one side of the pull rod is fixedly connected to the lower part of the moving jaw plate. A pull rod spring is installed on the other side of the pull rod, and the other side of the pull rod spring is fixedly connected to the inner wall of the built-in groove. A pad is installed at the connection between the pull rod and the pull rod spring, and a telescopic rod is installed inside the pull rod spring.

[0010] Preferably, a filter box is installed on one side of the top of the outer casing, and a filter plate is installed inside the filter box.

[0011] Preferably, a vacuum cleaner is installed on the top of the filter box, and suction pipes are installed at both ends of the vacuum cleaner.

An exhaust port is provided on the other side of the filter box.

[0012] Preferably, upright plates are installed at both ends of the bottom of the outer casing, and a base plate is installed at the bottom of the upright plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The present invention uses a vacuum cleaner that can adsorb the dust generated inside the crushing chamber through the suction pipe when the vacuum cleaner is working, and discharge the dust into the filter box through the exhaust pipe. The filter plate filters the dust and prevents the dust from being directly discharged to the outside. At the same time, an exhaust port is provided on one side of the filter box to facilitate the discharge of the filtered air, ensuring the cleanliness of the crusher's working environment. This solves the problem that when existing jaw crushers crush materials, the dust generated during the crushing process is directly discharged from the feed port due to the vibration of the box, which not only causes environmental pollution, but also has an adverse effect on the health of operators when exposed to such a working environment for a long time.

[0015] (2) The drive motor drives the drive wheel to rotate, and the belt drive can drive the driven wheel to rotate synchronously. The shaft can drive the eccentric shaft to rotate. Since the eccentric shaft and the moving jaw plate are connected by the moving jaw bearing, the rotation of the eccentric shaft will drive the moving jaw plate to reciprocate and squeeze with the stationary jaw plate, thereby crushing the material entering the crushing chamber. The electric push rod can drive the stationary jaw plate to follow the moving jaw plate to reciprocate, thereby avoiding the appearance of uncrushed material. This not only improves the crushing efficiency, but also ensures the consistency of the crushed particle size. The crushed material is gradually pushed to the discharge port by the movement of the moving jaw plate and finally discharged from the crusher.

[0016] (3) The elbow plate and the moving jaw plate are connected by bearings and fixed rods, which makes the moving jaw plate more stable during reciprocating motion and reduces unnecessary vibration and noise. The elbow seat, elbow plate and fixed rod work together to provide support and guidance for the moving jaw plate. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a high-energy jaw crusher, comprising a shell 1, a stationary jaw plate 2 installed on one side inside the shell 1, the stationary jaw plate 2 being fixedly connected to the inner wall of the shell 1 via multiple sets of electric push rods 3, a movable jaw plate 4 installed on the other side inside the shell 1, and fixed plates 9 installed at both ends of the top of the shell 1, with driven wheels 10 installed at one end opposite to the two fixed plates 9. (See also...) Figure 1A mounting plate 5 is installed at one end of the outer casing 1. A drive motor 7 is installed on the upper part of the mounting plate 5. The drive motor 7 is fixedly connected to the mounting plate 5 via a mounting base 6. A drive wheel 8 is installed on the output shaft of the drive motor 7. The drive wheel 8 and the driven wheel 10 at the same end are connected by a belt 11. A rotating shaft 12 is installed at one end of the two driven wheels 10 facing each other. An eccentric shaft 13 is installed through the fixed plate 9 via the rotating shaft 12. A through hole 14 is provided on the upper part of the moving jaw plate 4. The eccentric shaft 13 is fixedly connected to the rotating shaft 12 at both ends through the through hole 14. Moving jaw bearings 15 are installed at the connection between the eccentric shaft 13 and the two ends of the through hole 14. A crushing chamber 16 is set between the stationary jaw plate 2 and the moving jaw plate 4. A feed hopper 17 is installed on the top of the outer casing 1. A discharge port 18 is provided on the bottom of the outer casing 1. The material passes through... The feed hopper 17 enters the crushing chamber 16. The drive motor 7 is started, which drives the drive wheel 8 to rotate. Through the belt 11, the driven wheel 10 rotates synchronously, which in turn drives the eccentric shaft 13 to rotate via the rotating shaft 12. Since the eccentric shaft 13 is connected to the moving jaw plate 4 via the moving jaw bearing 15, the rotation of the eccentric shaft 13 causes the moving jaw plate 4 to reciprocate, creating pressure against the stationary jaw plate 2. This crushes the material entering the crushing chamber 16. The electric push rod 3 drives the stationary jaw plate 2 to follow the reciprocating motion of the moving jaw plate 4, thus preventing uncrushed material from entering. This not only improves crushing efficiency but also ensures consistent particle size. The crushed material is gradually pushed towards the discharge port 18 by the movement of the moving jaw plate 4 and is finally discharged from the crusher. Please refer to [link to relevant documentation]. Figure 2 and Figure 3 An elbow seat 19 is installed on the bottom side of the outer casing 1 near the movable jaw plate 4. An elbow plate 20 is rotatably connected to the elbow seat 19 and the movable jaw plate 4. Fixing rods 21 are installed inside both sides of the elbow plate 20. Fixing blocks 22 are installed at both ends of the side of the movable jaw plate 4 opposite to the elbow seat 19. The two ends of the fixing rods 21 are connected to the fixing blocks 22. Bearings 23 are installed at the connection between the fixing rods 21 and the fixing blocks 22. The elbow plate 20 and the movable jaw plate 4 are connected by the bearings 23 and the fixing rods 21, which makes the movable jaw plate 4 more stable during reciprocating motion and reduces unnecessary vibration and noise. The elbow seat 19, elbow plate 20 and fixing rods 21 work together to provide support and guidance for the movable jaw plate 4. Please refer to [link to relevant documentation]. Figure 2 A filter box 30 is installed on one side of the top of the outer casing 1, and a filter plate 31 is installed inside the filter box 30. Please refer to [link / reference]. Figure 2 and Figure 4A vacuum cleaner 32 is installed on the top of the filter box 30. Suction pipes 33 are installed at both ends of the vacuum cleaner 32. The other end of the suction pipe 33 passes through the outer shell 1 and is connected to the crushing chamber 16. An exhaust pipe 34 is installed on one side of the vacuum cleaner 32. The other end of the exhaust pipe 34 is connected to one side of the inside of the filter box 30. An exhaust port 35 is provided on the other side of the filter box 30. When the vacuum cleaner 32 is working, it can adsorb the dust generated inside the crushing chamber 16 through the suction pipe 33 and discharge the dust into the filter box 30 through the exhaust pipe 34. The dust is filtered by the filter plate 31 to prevent the dust from being directly discharged to the outside. At the same time, the exhaust port 35 on one side of the filter box 30 facilitates the discharge of the filtered air and ensures the cleanliness of the crusher's working environment.

[0024] Please see Figure 2 The lower part of the elbow seat 19 is provided with an internal groove 24. A circular hole 25 is provided on the side of the internal groove 24 near the moving jaw plate 4. A pull rod 26 is slidably connected inside the circular hole 25.

A pull rod spring 28 is installed on the other side of the pull rod 26, and the other side of the pull rod spring 28 is fixedly connected to the inner wall of the internal groove 24. A pad 27 is installed at the connection between the pull rod 26 and the pull rod spring 28. A telescopic rod 29 is installed inside the pull rod spring 28. The telescopic rod 29 allows the pull rod 26 to extend and retract under the action of the pull rod spring 28, thereby achieving precise control of the moving jaw plate 4. During the movement of the moving jaw plate 4, the pull rod spring 28 provides elastic force to the moving jaw plate 4, ensuring that the moving jaw plate 4 can smoothly open and close. The pad 27 reduces friction between the pull rod 26 and the pull rod spring 28, thereby extending the service life of the entire mechanism.
