Description

Technical Field

[0001] This utility model relates to the field of building aggregate processing technology, specifically a tilting building aggregate crushing device. Background Technology

[0002] Construction aggregates are granular materials that serve as the skeleton and filler in concrete and mortar, and can also reduce the shrinkage caused by cement hardening. Construction aggregates can be made from waste concrete, which is crushed into small particles using a crushing device during the processing.

[0003] According to the description in the patent application (CN 222724466 U) on the patent website, "This utility model discloses a building aggregate crushing device, including a box body. The top of the box body has a first feed inlet. Servo motors are fixedly connected to both the front and rear ends of the top right side of the box body. A rotating rod is fixedly connected to the output end of the servo motor. Crushing blades are fixedly connected to all four sides of the outer surface of the rotating rod. A collection box is provided at the bottom of the inner cavity of the box body, and a screening box is fixedly connected to the bottom left side of the inner cavity of the box body. This utility model uses a cylinder, a movable plate, and movable wheels at the bottom of the box body to facilitate movement when the device needs to be moved, eliminating the need for manual handling and meeting the needs of workers. By setting a screening box, a vibrating motor, and a vibrating screen plate at the bottom of the inner cavity of the box body, the crushed aggregate can be screened. Smaller aggregates fall into the collection box through the discharge port, while larger aggregates remain above the vibrating screen plate, thus facilitating subsequent use by workers and reducing their inconvenience."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model crushes building aggregates using a set crushing blade. However, due to the high hardness of the building aggregates, it is not convenient to crush them thoroughly using the crushing blade. Furthermore, after crushing, it is impossible to perform magnetic separation on the building aggregates. The magnetic metal objects (such as steel bars and angle steel) remaining inside can easily affect subsequent use. Therefore, it is necessary to improve the building aggregate crushing device to solve the above problems. Utility Model Content

[0030] To achieve crushing and magnetic separation of building aggregates, please refer to [link / reference]. Figure 1-5 This utility model provides a technical solution: a tilting construction aggregate crushing device, including a crushing chamber 1, a feed hopper 2 fixedly installed on the top of the crushing chamber 1, a discharge hopper 3 fixedly installed on the bottom of the crushing chamber 1, a support leg 4 fixedly installed on the outside of the crushing chamber 1, a crushing magnetic separation mechanism 5 extending from the inside to the outside of the crushing chamber 1, and a tilting screening mechanism 6 extending from the inside to the outside of the crushing chamber 1.

[0031] The crushing and magnetic separation mechanism 5 includes a crushing component 51 and a magnetic separation component 52. The crushing component 51 is disposed inside the crushing chamber 1 and extends to the outside, and the magnetic separation component 52 is disposed inside the crushing chamber 1 and extends to the outside.

[0032] The crushing assembly 51 includes a feed baffle 511, which is fixedly installed inside the crushing chamber 1 near the top. The right side of the crushing chamber 1 is fixedly installed on the drive motor 512 via a mounting bracket. The output end of the drive motor 512 is fixedly installed with a main crushing roller 513. An auxiliary crushing roller 514 is rotatably installed inside the crushing chamber 1 and extends to the outside. A first gear 515 is fixedly installed on the right side of the auxiliary crushing roller 514. A second gear 516 is fixedly installed on the output end of the drive motor 512, and the first gear 515 and the second gear 516 mesh with each other. A magnetic separation baffle 517 is fixedly installed on the inner back wall of the crushing chamber 1 to facilitate the crushing and processing of waste concrete.

[0033] Furthermore, there are two feed baffles 511, and the two feed baffles 511 are symmetrically distributed around the center line of the right side of the crushing chamber 1, so that the waste concrete can be concentrated and enter between the main crushing roller 513 and the auxiliary crushing roller 514.

[0034] Furthermore, the magnetic separation assembly 52 includes a screening baffle 521, which is fixedly installed on the inner front wall of the crushing chamber 1. A magnetic separation discharge plate 522 is fixedly installed on the inner back wall of the crushing chamber 1. A magnetic separator 523 is rotatably installed inside the crushing chamber 1 extending to the left side. A permanent magnet 524 is fixedly installed on the inner right side of the crushing chamber 1. A first synchronous wheel 525 is fixedly installed on the left side of the magnetic separator 523. A second synchronous wheel 526 is fixedly installed on the left side of the main crushing roller 513 extending to the outside. A synchronous belt 527 is installed between the first synchronous wheel 525 and the second synchronous wheel 526 to facilitate magnetic separation of the crushed building aggregate.

[0035] Furthermore, a discharge port is provided on the back of the crushing chamber 1 at the corresponding position of the magnetic separation discharge baffle to facilitate the discharge of magnetic metal objects separated by magnetic separation from the crushing chamber 1.

[0036] Furthermore, multiple sets of permanent magnets 524 are arranged in a circumferential array and attached to the inner wall of the magnetic separator 523 to facilitate the adsorption of magnetic metal objects in building aggregates. Example

[0037] To perform screening of building aggregates, please refer to [link / reference]. Figure 6Furthermore, in conjunction with Embodiment 1, it is further found that the tilting screening mechanism 6 includes a bidirectional motor 61, which is fixedly installed on the inner wall of the front of the crushing chamber 1. Turntables 62 are fixedly installed on the two output ends of the bidirectional motor 61. Screening plates 63 are rotatably installed on the inner wall of the back of the crushing chamber 1. Connecting rods 64 are rotatably installed between the two ends of the screening plate 63 near the front side and the two side screening plates 63, so as to facilitate the screening of building aggregates.

[0038] Furthermore, a discharge port is provided on the front of the crushing chamber 1 at the corresponding position of the screening plate 63, so as to facilitate the discharge of building aggregates that cannot pass through the screening plate 63 from the crushing chamber 1.

[0039] Furthermore, the end of the connecting rod 64 away from the screening plate 63 is rotatably mounted at the eccentric position of the turntable 62, which facilitates the turntable 62 to drive the screening plate 63 to reciprocate and shake.

[0040] In actual operation, when this device is in use, construction waste concrete is fed into the feed hopper 2. The drive motor 512 drives the main crushing roller 513 to rotate, which in turn drives the first gear 515 to rotate. The first gear 515 drives the auxiliary crushing roller 514 to rotate synchronously in the opposite direction through the meshing second gear 516. This causes the main crushing roller 513 and the auxiliary crushing roller 514 to rotate synchronously in the opposite direction, thus crushing the construction waste concrete. The crushed concrete falls onto the magnetic separator 517 and is conveyed downwards through the magnetic separator. At the same time, it is transported by the main crushing roller... The crushing roller 513 drives the second synchronous wheel 526 to rotate, which in turn drives the first synchronous wheel 525 to rotate via the synchronous belt 527. The first synchronous wheel 525 then drives the magnetic separator 523 to rotate. The magnetic metal objects in the crushed building aggregate are attracted by the permanent magnet 524 inside the magnetic separator 523, and the magnetic metal objects are conveyed backward by the magnetic separator 523. When the magnetic separator rotates to the end without the permanent magnet 524, the magnetic metal objects fall onto the magnetic separator discharge plate 522 and are discharged by the magnetic separator discharge plate 522.

[0041] After magnetic separation, the building aggregate falls onto the screening plate 63. The turntable 62 is driven to rotate by the bidirectional motor 61, which in turn drives the screening plate 63 to reciprocate through the connecting rod 64. This causes the screening plate 63 to vibrate back and forth, thus screening the building aggregate. Small building aggregate passes through the screening plate 63 and is discharged through the discharge hopper 3, while large building aggregate passes through the screening plate 63 and is discharged from the front of the crushing chamber 1.
