[0002] Eco-plastic wood wallboard is an environmentally friendly building material, usually composed of high-density polyethylene, wood powder and other auxiliary materials. Compared with traditional wooden wallboards, ecological plastic wood wallboards have better weather resistance and anti-corrosion properties, and are not easily affected by wind, rain, insect pests or rot. In addition, the production process of ecological plastic wood wallboards does not require a large amount of wood resources, which can reduce damage to the environment. In the production of ecological plastic wood wallboards, wood powder and raw materials such as high-density polyethylene need to be fully mixed and crushed. However, the existing crushers used for ecological plastic wood wallboards cannot better screen the fragments of different particle sizes after the crushing. The wood and plastic fragments are easily attached to the screen due to the heat of the crushing, which affects the screening effect and the feeding speed, thereby reducing the screening efficiency.

[0003] In view of the above problems, a screening structure of a crusher for producing ecological plastic wood wallboard is proposed to solve the above problems. Utility Model Content

The screening mechanism 5 also includes a sieve plate 52, and a clamping block 522 is rotatably connected to the outer side of the sieve plate 52, and both ends of the clamping block 522 are clamped in the inner groove 513. The sieve plate 52 is movably connected to the inner side of the movable groove 512, and a sieve 521 is fixedly connected to the upper surface of the sieve plate 52. The outer surface of the sieve plate 52 A rotating rod 524 is fixedly connected to the side, and a mounting plate 13 is fixedly connected to the inner wall of the main box body 1. The rotating rod 524 is rotatably connected to the inner wall of the mounting plate 13.

The motor A514 drives the rotating shaft 515 and the eccentric wheel 516 to rotate, and then the upper screen plate 52 vibrates, thereby accelerating the screening and preventing the broken materials from clogging the screen 521. Through the arrangement of the block 522 and the inner groove 513, the up and down vibration of the screen plate 52 is limited to a certain extent, ensuring that the screen plate 52 always has a stable vibration amplitude. Through the arrangement of the mounting plate 13 and the rotating rod 524, the angle of the screen plate 52 can be adjusted to facilitate the vibration of the screen plate 52.

[0027] A buffer pad 523 is fixedly connected to the bottom surface of the sieve plate 52 . The buffer pad 523 fits the surface of the eccentric wheel 516 . The arrangement of the buffer pad 523 provides a certain protection and buffering effect on the vibration of the sieve plate 52 .

[0028] The screening mechanism 5 also includes an anti-blocking component 53 for preventing the screen 521 from being blocked. The anti-blocking component 53 includes an electric telescopic rod 531 fixedly connected to the bottom surface of the screen plate 52.

There are two groups of feed plates 11, and the two groups of feed plates 11 are symmetrically arranged. A crushing roller 12 is rotatably connected to the inside of the main box body 1, and the crushing roller 12 is externally connected to a motor. Through the arrangement of the feed plate 11, the feed hopper 3 and the crushing roller 12, the purpose of facilitating feeding and guiding the material to the crushing roller 12 for crushing is achieved.

[0033] An inclined bottom surface 14 is fixedly connected to the inner wall of the main box body 1, and a valve A15 is fixedly connected to the bottom surface of the main box body 1. The inclination direction of the inclined bottom surface 14 corresponds to the opening direction of the valve A15. A bracket 4 is fixedly connected to the bottom surface of the main box body 1. The arrangement of the inclined bottom surface 14 and the valve A15 facilitates the discharge of materials inside the main box body 1. The arrangement of the bracket 4 provides stable conditions for crushing and screening work.

[0034] Specifically, the raw material falls after being crushed by the crushing roller 12, and the debris falls on the upper surface of the screen 521. At this time, the motor A514 is turned on, and the motor A514 drives the rotating shaft 515 and the eccentric wheel 516 to rotate, thereby driving the screen plate 52 to vibrate up and down. Due to the inclined setting of the screen plate 52, the debris above the vibrating screen plate 52 gradually falls downward, and the larger ones move to the side of the screen plate 52 with the vibration, and fall into the side box 2 through the discharge chute 517 and the valve B16 for collection. In addition, during the screening process, the electric telescopic rod 531 is turned on, and the electric telescopic rod 531 drives the push plate 532 and the cleaning cotton 533 to move against the bottom surface of the screen 521, so as to clean the screen 521 without affecting the normal material discharge, and prevent the screen 521 from being blocked, thereby finally achieving the purpose of facilitating the screen plate 52 to screen and discharge materials and prevent blockage.
