Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a gap adjustment mechanism for a crusher discharge port. Background Art

[0002] In daily work, crusher is an indispensable tool for people, which can help us grind materials into particles. The double-roll crusher is a mechanical equipment that uses two sets of separately driven rollers to generate extrusion force and shear force to crush materials through relative rotation.

[0003] In some equipment on the market, after the material enters the crushing chamber of the machine, it is subjected to the meshing force of the rotating rollers, so that the material is forced to pass between the two rollers. At the same time, it is squeezed and sheared by the rollers, and the material begins to break. The broken small particles follow the tangent of the roller rotation, pass through the gap between the two rollers, and are thrown to the bottom of the machine. The large particles that exceed the gap continue to be broken into small particles and discharged.

[0004] However, in the actual use of the above equipment, when the material is crushed, some larger particles are not crushed and popped out and discharged, so that smaller materials are discharged together with larger materials, making it difficult for workers to separate the materials well; in view of this, we propose a gap adjustment mechanism for the crusher discharge port. Summary of the invention

[0005] The utility model aims to provide a gap adjustment mechanism for a crusher discharge port to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a crusher discharge port gap adjustment mechanism, comprising a shell, the upper surface of the shell is provided with a feed port, the bottom of the shell is provided with a discharge port, one side of the inner wall of the shell is rotatably connected to a crushing roller, and a separation device is provided inside the shell, and the separation device includes:

[0007] A guide block, one side of the inner wall of the shell is fixedly connected with the guide block, the guide block is arranged in a right-angle trapezoidal shape, and one side of the inner wall of the shell is rotatably connected with an inclined plate;

[0008] A discharge port is provided on one side of the shell, a fixed block is fixedly connected to one side of the inner wall of the shell near the inclined plate, an electric telescopic rod is fixedly connected to the upper surface of the fixed block, and a filter plate is movably connected to the top of the electric telescopic rod;

[0009] A collecting piece is sleeved inside the discharge port, and the collecting piece is arranged as a special-shaped piece, consisting of a rectangular parallelepiped and a truncated cone.

[0010] Preferably, the filter plate is arranged at an angle, and one end of the filter plate is hinged to the bottom of the inner wall of the discharge port, which allows the filter plate to move well.

[0011] Preferably, the size of the collecting member matches the size of the interior of the shell, and the size of the collecting member matches the size of the discharge port, which allows the collecting member to move inside the discharge port.

[0012] Preferably, the size of the guide block is matched with the size of the interior of the shell, and the collecting member is located below the discharge port.

[0013] Preferably, a movable groove is opened on the inner wall of the shell, a spring is fixedly connected to the bottom of the inner wall of the movable groove, one end of the spring is fixedly connected to a movable plate, and one side of the movable plate is fixedly connected to a collecting piece.

[0014] Preferably, the movable plate is arranged inside the movable groove, and the position of the movable groove corresponds to the position of the collecting member.

[0015] Compared with the prior art, the utility model provides a crusher discharge port gap adjustment mechanism, which has the following beneficial effects:

[0016] 1. The gap adjustment mechanism of the crusher discharge port is to prevent some incompletely crushed materials from being unable to be distinguished. The materials are put into the feed port and the crushing rollers are allowed to crush the materials. The crushed materials fall on the inclined surface set on the upper surface of the guide block. The materials slide on the upper surface of the guide block and collide with the inclined plate, and then fall to the upper surface of the filter plate. At this time, the electric telescopic rod is stretched for a period of time and then contracts, so that the filter plate vibrates, so that the filter plate can filter the materials well, so that larger materials are discharged from the upper surface of the filter plate through the discharge port, and smaller materials fall into the inside of the collecting piece and are discharged from the discharge port. At the same time, the electric telescopic rod is stretched to raise one end of the filter plate, so that the gap between the inclined plate and the guide block becomes smaller, so that the discharge of materials can be adjusted.

[0017] 2. The crusher has a gap adjustment mechanism for the discharge port. In order to make the material be discharged better, when the material falls into the collecting piece, the weight of the material will cause the collecting piece to move downward, so that the movable plate presses the spring. The pressure on the spring will cause the collecting piece to move up and down continuously, so that the material falling into the collecting piece can be vibrated and move toward the discharge port, so that the material can be discharged better.

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a crusher discharge port gap adjustment mechanism, comprising a shell 1, a feed port 2 is arranged on the upper surface of the shell 1, a discharge port 3 is opened at the bottom of the shell 1, a crushing roller 4 is rotatably connected to one side of the inner wall of the shell 1, and a separation device is arranged inside the shell 1, and the separation device includes a guide block 5, an inclined plate 6, a filter plate 7, a discharge port 10, a fixed block 8, an electric telescopic rod 9, the filter plate 7 and a collecting piece 11.

[0024] In the embodiment of the utility model, a guide block 5 is fixedly connected to one side of the inner wall of the shell 1. The guide block 5 is set in a right-angled trapezoid. The size of the guide block 5 is adapted to the size of the inside of the shell 1. An inclined plate 6 is rotatably connected to one side of the inner wall of the shell 1. The universal shaft set on one side of the inclined plate 6 is rotatably connected to the inner wall of the shell 1, and the bottom of the inclined plate 6 is always in contact with the upper surface of the filter plate 7. A discharge port 10 is provided on one side of the shell 1. A fixed block 8 is fixedly connected to one side of the inner wall of the shell 1 near the inclined plate 6. An electric telescopic rod 9 is fixedly connected to the upper surface of the fixed block 8. The filter plate 7 is movably connected to the top of the electric telescopic rod 9. The top plate of the electric telescopic rod 9 is hinged with a movable block, and the movable block is clamped in the inside of the slide groove opened at the bottom of the filter plate 7. In this way, when the electric telescopic rod 9 is extended, the movable block can move in the slide groove to lift one end of the filter plate 7. The filter plate 7 is tilted, and one end of the filter plate 7 is hinged at the bottom of the inner wall of the discharge port 10, which can make the filter plate 7 move well. The collecting piece 11 is provided in a special-shaped piece, which is composed of a rectangular parallelepiped and a truncated cone. The size of the collecting piece 11 is adapted to the size of the inside of the shell 1, and the size of the collecting piece 11 is adapted to the size of the discharge port 3, which can make the collecting piece 11 move inside the discharge port 3, and the position of the collecting piece 11 is below the discharge port 10. A movable groove 12 is provided on the inner wall of the shell 1, and the position of the movable groove 12 corresponds to the position of the collecting piece 11. A spring 13 is fixedly connected to the bottom of the inner wall of the movable groove 12, and a movable plate 14 is fixedly connected to one end of the spring 13. The movable plate 14 is arranged in the movable groove 12, and the collecting piece 11 is fixedly connected to one side of the movable plate 14. When the material falls into the collecting piece 11, the weight of the material will cause the collecting piece 11 to move downward, so that the movable plate 14 presses the spring 13, and the pressure on the spring 13 will cause the collecting piece 11 to move up and down continuously, so that the material falling into the collecting piece 11 can be vibrated to move toward the discharge port 10, so that the material can be discharged better.

[0025] In the utility model, when in use, the material is put in from the feed port 2, and the crushing roller 4 is allowed to crush the material. The crushed material falls on the inclined surface set on the upper surface of the guide block 5, and the material slides on the upper surface of the guide block 5 and collides with the inclined plate 6, and then falls to the upper surface of the filter plate 7. At this time, the electric telescopic rod 9 is stretched for a period of time and then contracts, so that the filter plate 7 vibrates, so that the filter plate 7 can filter the material well, so that the larger material is discharged from the upper surface of the filter plate 7 through the discharge port 10, and the smaller material falls into the collecting part 11 and is discharged from the discharge port 3. At the same time, the electric telescopic rod 9 is stretched to lift one end of the filter plate 7, so that the gap between the inclined plate 6 and the guide block 5 becomes smaller, so that the discharge of the material is adjusted.

[0026] Furthermore, when the material falls into the collecting piece 11, the weight of the material will cause the collecting piece 11 to move downward, causing the movable plate 14 to press the spring 13. The pressure on the spring 13 will cause the collecting piece 11 to move up and down continuously, so that the material falling into the collecting piece 11 can be vibrated and moved toward the discharge port 10, allowing the material to be discharged better.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
