Description

Technical Field

[0001] The utility model relates to a recycled aggregate production device, and particularly to a conical crusher for recycled aggregates. Background Art

[0002] At present, a Chinese patent with the publication number CN209549572U discloses a conical crusher, which includes a transmission shaft, a moving cone, a main shaft and a crushing wall. The transmission shaft rotates driven by a motor. An eccentric sleeve is provided at the lower end of the moving cone. The eccentric sleeve is sleeved on the main shaft. The transmission shaft drives the eccentric sleeve to rotate axially around the main shaft through a transmission structure. The moving cone generates an eccentricity under the action of the eccentric sleeve and makes a swinging motion, so that the distance between the moving cone and the crushing wall is sometimes close and sometimes far, so that the material is continuously crushed under extrusion, breaking and impact in the crushing cavity. However, during the use of the above conical crusher, the material is likely to fly out from the top opening of the crushing wall under strong impact, causing harm to the staff guarding the crusher, and there is a defect of low use safety. Summary of the Invention

[0003] In view of this, the purpose of the utility model is to provide a conical crusher for recycled aggregates, which has the advantage of high use safety.

A plurality of support rods are provided at the upper end of the crusher body. The plurality of support rods are evenly distributed along the circumferential direction of the crusher body. The support rods are inclined, and the upper ends of the support rods extend towards one side of the central axis of the crusher body. A slag blocking net plate is arranged between two adjacent support rods, and the slag blocking net plate is used to block the splashing material.

[0005] Through the above technical solution, during use, the slag blocking net plate arranged at the upper end of the crusher body can block the splashing material, so it is not easy to cause harm to the staff guarding the crusher. The support rods arranged on both sides of the slag blocking net plate can be used to support the slag blocking net plate, so that the slag blocking net plate has high strength and is not easy to deform when touching the splashing material. The upper ends of the support rods extend towards one side of the central axis of the crusher body, which can be used to more effectively block the splashing material, so that the material is not easy to impact on the operator. In summary, the above crusher has the advantage of high use safety.

[0006] Preferably, the slag blocking net plate includes a net plate frame connected to the side wall of the support rod and a slag blocking net body arranged inside the net plate frame. The slag blocking net body is woven by metal wires.

A T-shaped sliding block is provided at the side wall of the mesh frame, and the T-shaped sliding block is slidably connected in the T-shaped sliding groove.

[0009] Through the above technical solution, the T-shaped sliding groove and the T-shaped sliding block cooperate with each other to slide the slag retaining mesh plate and the support rod to connect them, making the disassembly and assembly of the slag retaining mesh plate more convenient.

[0010] Preferably, the length of the T-shaped sliding groove is greater than the length of the T-shaped sliding block, and a connecting hole is provided on the side wall of the support rod, and the two ends of the connecting hole are respectively connected to the T-shaped sliding grooves on both sides of the support rod, and a blocking rod is inserted in the connecting hole, and the blocking rod simultaneously presses against the upper ends of the two T-shaped sliding blocks.

[0011] Through the above technical solution, the retaining rod simultaneously presses against the upper ends of the two T-shaped sliding blocks to limit the T-shaped sliding blocks, so that the T-shaped sliding blocks are not easy to slide out of the T-shaped sliding groove, which helps to improve the connection stability of the slag retaining mesh plate.

[0012] Preferably, an internal thread is provided on the inner wall of the connecting hole, and the blocking rod comprises a connecting rod body threadedly connected to the connecting hole, and abutment sleeves rotatably sleeved on both ends of the connecting rod body, and the abutment sleeves are tightly pressed against the T-shaped sliding block on the same side.

[0013] Through the above technical solution, the connecting rod body is threadedly connected in the connecting hole, has a high connection strength, and is not easily separated from the support rod during use. The abutment sleeve is rotatably sleeved on both ends of the connecting rod body and abuts against the T-shaped sliding block, so that when the connecting rod body is rotated to be threadedly connected to the connecting hole, the T-shaped sliding block is not easy to hinder the rotation of the connecting rod body.

[0014] Preferably, a positioning ring groove is provided at the end of the connecting rod body, and the positioning ring groove extends along the circumference of the connecting rod body. A countersunk hole is provided on the outer wall of the abutment sleeve, and the countersunk hole extends along the radial direction of the connecting rod body and is connected to the positioning ring groove. A positioning bolt is threadedly connected in the countersunk hole, and the threaded end of the positioning bolt extends into the positioning ring groove and is slidably connected to the positioning ring groove.

[0015] Through the above technical solution, after the connecting rod body is threadedly connected to the connecting hole, the abutting sleeve is sleeved on the end of the connecting rod body so that the counterbore is communicated with the positioning ring groove, and then the positioning bolt is tightened so that the threaded section of the positioning bolt extends into the positioning ring groove. At this time, the positioning bolt cooperates with the positioning ring groove and can be used to limit the axial movement of the abutting sleeve.

[0016] Preferably, a guiding cover is arranged above the plurality of support rods, and the guiding cover is flared to guide the material into the crusher body.

[0017] Through the above technical solution, the flared guiding cover can guide the material into the crusher body to improve the feeding efficiency of the crusher.

[0018] Preferably, a plug-in groove is formed at the upper end of the support rod, and a plug-in block corresponding to the plug-in groove is arranged at the lower end of the guiding cover, and the plug-in block is plugged and fixed in the corresponding plug-in groove.

[0019] Through the above technical solution, the cooperation of the plug-in groove and the plug-in block can be used to detachably connect the guiding cover to the plurality of support rods, making the disassembly and assembly process of the guiding cover more convenient.
