Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mixing station screening equipment, in particular to a leakage port anti-blocking type mixing station screening device. Background Art
[0002] The screening device of a mixing station refers to a device used to screen and grade particles in concrete or other building materials. It usually consists of a screen, a feeding device, a driving device and a supporting structure. The screening device of a mixing station separates the raw material particles according to the particle size by vibration or rotation to meet the particle grading requirements in different engineering requirements. It plays the role of screening, filtering and grading in the mixing station, which can effectively improve the quality of concrete and construction efficiency.
[0003] The existing mixing station screening device generally has multiple discharge ports, among which the smaller discharge port lacks an effective anti-blocking structure. When materials with larger particles or stronger viscosity pass through the outlet, it is easy to cause blockage. Blockage will prevent the material from flowing out normally, affecting production efficiency. If the discharge port lacks an effective anti-blocking structure, it will become difficult to clean up after blockage. The operator needs to spend more time and energy to clean the blocked discharge port, which increases the difficulty and cost of maintenance. The probability of blockage may increase, resulting in increased downtime. Therefore, we hope to design a mixing station screening device with a new structure to solve this problem.

[0006] The discharging assembly includes discharging port 1, discharging port 2, discharging port 3, discharging port 4 and discharging port 5, and the discharging port 1 is fixed at the upper end of the discharging port 4;
[0007] The front left side of the discharge port 4 is provided with a discharge port 2, the front right side of the discharge port 4 is provided with a discharge port 3, and the rear side of the discharge port 4 is fixed with a discharge port 5;
[0008] The discharge port 5 is disposed at the lower end of the vibration screen body, and a locking piece is movably inserted on the upper sides of the discharge port 2 and the discharge port 3.

At this time, the tension spring is stretched, and the recovery potential energy of the tension spring cooperates with the connecting rod one and the connecting rod two to limit the movable plate two. Under the premise of ensuring normal material guiding, the expansion of the discharge cross section is completed, which effectively avoids the blockage of the discharge port four. Even if the material is blocked, it is convenient to clean it. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] See also Figures 1 to 4 The utility model provides a technical solution: a leakage port anti-blocking type mixing station screening device, comprising: a frame 100, a vibrating screen body 200 and a discharging assembly 300, the vibrating screen body 200 is installed on the upper side of the frame 100, and the front end of the vibrating screen body 200 is installed with a discharging assembly 300 for classifying and discharging materials;
[0027] The discharge assembly 300 includes a discharge port 1 310, a discharge port 2 320, a discharge port 3 330, a discharge port 4 340 and a discharge port 5 350. The discharge port 1 310 is fixed at the upper end of the discharge port 4 340.

The movable plate 331 is tilted, and an insert cylinder 332 is provided on the lower side of the upper surface of the movable plate 331. By arranging a movable movable plate 331 on the outer sides of the second discharge port 320 and the third discharge port 330 with smaller outlet cross-sections, the movable plate 331 can be contacted and fixed when needed to be in an active state, which can increase the outlet cross-section, reduce the probability of blockage, and make it convenient to clean the blockage.

[0034] As the first embodiment of the utility model, in actual use, if the batch of materials is prone to congestion at the second discharge port 320 and the third discharge port 330, the user can hold the handle 362 and pull out the insertion rod 1 361 and the second insertion rod 363 from the inside of the insertion tube 1 332 and the second insertion tube 333 respectively.

The movable plate 2 341 is hinged on both sides of the discharge port 4 340 with a smaller outlet cross-section, so that when the material is blocked, the discharge cross-section can be automatically expanded under the squeeze of the material, which greatly reduces the probability of blockage and is also convenient for cleaning.
[0037] As the second embodiment of the utility model, based on the above-mentioned first embodiment, in actual use, once the material discharged from the discharge port four 340 is blocked, the movable plates two 341 on both sides of the discharge port will be squeezed outward under the extrusion of the material, and the tension spring 344 is stretched at this time. The restoring potential energy of the tension spring 344 cooperates with the connecting rod one 342 and the connecting rod two 343 to limit the movable plate two 341. Under the premise of ensuring normal material guiding, the expansion of the discharge cross section is completed, and the blockage of the discharge port four 340 is effectively avoided.
