Description

Technical Field

[0001] The utility model relates to the technical field of crushers, and more specifically to an anti-blocking crusher. Background Art

[0002] Hammer crusher is an impact rotor crusher with a hammer. After the material enters the crusher, it is first crushed by the high-speed hammer. The smaller the crushed material is, the more it will be discharged from the discharge port at the lower end of the crusher. The larger material will continue to be further crushed by the shearing, squeezing, grinding of the hammer and the mutual collision of the materials in the crusher until the volume meets the requirements and the material is discharged.

[0003] At present, the existing hammer crushers are prone to sticking in the feed port when crushing materials with high moisture content and high viscosity, which may even cause blockage of the feed port in severe cases. In addition, in the "collection and preparation" link of bulk material management in enterprises, crushers are also important sample preparation equipment. The problem of mixed samples caused by residual samples in the crusher has not been fundamentally solved. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides an anti-blocking crusher which overcomes the above technical problems or at least partially solves the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An anti-blocking crusher comprises a crushing machine body; a sealing baffle is provided at the feed inlet on the upper part of the circular cavity of the crushing machine body;

[0007] One end of the sealing baffle is hinged to the crushing machine body, and the other end is a free end. The sealing baffle can be rotated to engage and seal the feed opening of the crushing machine body, and form a complete crusher shell with the crushing machine body.

[0008] Preferably, a feed portion is provided at the feed port of the crushing machine body, a feed baffle is fixedly connected to the free end of the sealing baffle, and the feed baffle is driven by the sealing baffle to block the discharge port of the feed portion.

[0009] Preferably, the size of the feed baffle is greater than or equal to the size of the discharge port of the feed part.

[0010] Preferably, the end of the feed baffle away from the sealing baffle is made of ferromagnetic material, the free end of the sealing baffle is made of ferromagnetic material, and a magnet is provided at one end of the feed portion close to the feed baffle.

[0011] Preferably, the sealing baffle is an arc plate structure.

[0012] Preferably, it also includes a rotating shaft, which is located in the crusher body and one end of which is driven to rotate by a power device; a plurality of connecting rods are arranged along the axial direction of the rotating shaft, and a ring hammer connected by a pin is installed at the outer end of each connecting rod.

[0013] Preferably, the ring hammer includes a round hammer with a smooth surface and a flower hammer with a protrusion on the surface, and the round hammers or flower hammers are installed at both ends of the same connecting rod, and the round hammers and the flower hammers are arranged alternately.

[0014] It can be seen from the above technical solutions that, compared with the prior art, the utility model discloses a blockage-proof crusher, which has the following beneficial effects:

[0015] The utility model is designed with a sealing baffle, which is hinged to the crushing body, so as to realize the closing and opening of the feed port of the crushing body and control the entry of materials; and when the sealing baffle closes the feed port of the crushing body, the movement of the ring hammer can clean up the materials stuck to the side of the feed baffle close to the ring hammer, so as to avoid the problem of sample mixing caused by residual samples in the crusher.

[0016] In the utility model, one end of the sealing baffle is hingedly connected to the crushing body by a hinge or a fixed rotating shaft. Through the above design, the sealing baffle can realize the closing and opening of the crushing body feed port; the sealing baffle makes an arc motion around the hinge or the fixed rotating shaft, and when feeding, the sealing baffle opens to open the crushing body feed port; when it is necessary to clean the material stuck on the side of the sealing baffle, the sealing baffle closes and opens the crushing body feed port; and with the movement of the sealing baffle, the feed baffle fixedly connected to one end of the sealing baffle can also realize the closing and opening of the feed outlet of the feed part.

[0017] The utility model is designed that the end of the feed baffle away from the sealing baffle is made of ferromagnetic material, the free end of the sealing baffle is made of ferromagnetic material, and a magnet is provided at one end of the feed part close to the feed baffle. The magnet and the feed baffle made of ferromagnetic material attract each other. When the sealing baffle opens the feed port of the crushing body, the sealing baffle and the feed part are attracted to each other to prevent materials from falling out of the crushing body. When the sealing baffle closes the feed port of the crushing body, the feed baffle can more firmly close the feed port of the feed part. At the same time, the sealing baffle can also more stably close the feed port of the crushing body, making it convenient for the ring hammer to scrape off materials with higher viscosity on the sealing baffle.
