Abstract
Description
Technical Field
[0001] The utility model relates to a crushing device with a large-block intercepting structure, belonging to the field of crushing devices. Background Art
[0002] Gypsum crushing equipment is a device used to crush, refine, and process materials such as gypsum. These devices are primarily used to crush waste gypsum board, recycled gypsum, or other similar materials for recycling or reprocessing. However, if the crushing equipment fails to filter out bulky materials, the crushing process will increase the impact and load on the equipment during operation, increasing the risk of damage. This can also affect the uniformity and fineness of the crushing, resulting in substandard particles. Therefore, we sought to design a crushing device with a bulk interception structure to address this issue. Utility Model Content
[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a crushing device with a large-block interception structure to solve the problems raised in the above background technology.

[0020] See also Figures 1 to 4 The utility model provides a technical solution: a crushing device with a large-block intercepting structure, comprising a material blocking box 100 and a crushing mechanism 300, wherein a sieve plate 200 is provided inside the material blocking box 100, a discharge port 110 is provided on the front surface of the material blocking box 100, the discharge port 110 is located above the sieve plate 200, and a crushing mechanism 300 is installed below the sieve plate 200;
[0021] The crushing mechanism 300 includes a crushing roller 310 and crushing teeth 330 . A crushing mechanism 500 is installed on the bottom of the crushing mechanism 300 . The crushing mechanism 500 includes a funnel 400 , a turntable 510 , a disc 520 and a rotating shaft 530 . A bottom plate 550 is installed on the bottom of the crushing mechanism 500 .
[0022] A sieve hole 210 is opened on the surface of the sieve plate 200, and a vibration motor 120 is fixed at the center of the bottom surface of the sieve plate 200. The sieve plate 200 is inclined at an angle with the front lower and the back higher. The vibration motor 120 vibrates to make the material pass through the sieve hole 210 to prevent the material from accumulating on the upper surface of the sieve plate 200.
[0023] The crushing mechanism 300 consists of a crushing roller 310 and crushing teeth 330. A plurality of crushing teeth 330 are provided on the surface of the crushing roller 310. A sieve plate 2 410 is installed on the lower side of the crushing roller 310. A plurality of sieve holes 2 420 are provided on the surface of the sieve plate 2 410. The sieve holes 2 420 can allow materials that do not meet the specifications to remain on the upper surface of the sieve plate 2 410 and continue to be crushed by the crushing teeth 330 until they can pass through the sieve holes 2 420.
[0024] Two groups of crushing rollers 310 are symmetrically installed on the left and right sides of the material blocking box 100. Motor 1 340 is installed on the rear side of the two groups of crushing rollers 310. The two groups of motors 1 340 rotate in opposite phases. A rotating rod 320 is installed at the center of the crushing rollers 310. Motor 1 340 is connected to the rotating rod 320. The two groups of crushing mechanisms 300 are driven by motor 1 340 to rotate in opposite phases to crush the material.
[0025] A turntable 510 is installed at the center of the rolling mechanism 500. Grinding blocks are provided on the surface and bottom of the turntable 510. The cross section of the turntable 510 is conical, and the diameter of the bottom of the turntable 510 is smaller than the diameter of the disc 520.
[0026] Grooves are provided on the upper and lower surfaces of the disc 520 . The diameter of the disc 520 is smaller than that of the bottom plate 550 . The disc 520 is a flat cylindrical structure. The bottom plate 550 is installed below the funnel. A rotating shaft 530 is installed at the center of the bottom plate 550 .
[0027] The upper end of the rotating shaft 530 is connected to the turntable 510, and the lower end of the rotating shaft 530 is connected to the motor 2 341. A disc 520 is installed on the surface of the rotating shaft 530. The disc 520 is located between the turntable 510 and the bottom plate 550. The bottom plate 550 is provided with a plurality of discharge holes 540. The motor 2 341 drives the disc 520 and the turntable 510 to rotate and grind through the rotating shaft 530, and the cooperation between the grinding block and the groove can make the material reach a more delicate state and then pass through the discharge port 540.
[0028] See also Figure 3 As the first embodiment of the present utility model: when the machine is operating, the staff puts the material into the material blocking box 100 for preliminary screening and filtering. The large pieces of material will be blocked on the upper surface of the sieve plate 200 and then fall to the outside of the material blocking box 100 under the influence of the vibration motor 120 and gravity, which plays the role of screening and intercepting the large pieces of material. When the material specification is smaller than the diameter of the sieve hole 210, it will enter the inside of the crushing mechanism 300 through the sieve hole 210 and be preliminarily crushed by the cooperation of the crushing roller 310 and the crushing teeth 330. When the material after preliminary crushing is larger than the diameter of the sieve hole 2 420, the sieve plate 2 410 and the sieve hole 2 420 will intercept it, so that the material will stay on the upper surface of the sieve plate 2 410 and continue to be crushed until it can pass through the sieve hole 2 420 and fall into the inside of the rolling mechanism 500.
[0029] See also Figure 4 As the second embodiment of the present invention: when the material passes through the screen plate 2 410 and enters the crushing mechanism 500, the material will be accumulated in the funnel 400. Due to the downward pressure generated by the gravity of the material itself, the cooperation between the turntable 510 and the inner wall of the discharge barrel 560 can further grind the material after the preliminary crushing. The grinding blocks arranged on the surface of the turntable 510 can increase the friction. After the grinding is completed on the turntable 510, the material will continue to fall on the upper surface of the disc 520 and the upper surface of the bottom plate 550. The discharge hole 540 provided on the bottom plate 550 can allow the material that cannot pass through to continue to be ground by the turntable 510 and the disc 520 until the size of the material is smaller than the diameter of the discharge hole 540, and then discharged outward through the discharge hole 540.
