Problems solved by technology

[0003] At present, the sieve rollers of the existing crusher sieve roller discharge structure are used to discharge the material through the gap between the sieve rollers. Since the surface of the sieve roller is a smooth structure, the force of the belt material is relatively small. If it is slightly larger than If there are gaps in the material, there will be a problem that the material cannot be unloaded, which will affect the effect of unloading the broken material and increase the cost of manual cleaning.

Embodiment

[0028] When in use, turn on the sieve roller drive motor. Driven by the driving gear, the two driven gears rotate inward at the same time. The material falls into the screening gap between the first sieve roller and the second sieve roller. The second sieve roll rotates inward, because the teeth of the first sieve roll and the second sieve roll are placed corresponding to the sieving gap of the first sieve roll and the second sieve roll, the roller teeth press the material into the sieving gap, inward After being rotated, it falls into the lower silo, which can also achieve the effect of further crushing.

[0029] If there is material stuck in the sieving gap with the first sieve roller and the second sieve roller rotating, when it passes the bottom end, it will contact with the scraping teeth at the end of the scraping part arranged obliquely, and the stuck material It will be blocked by the scraper teeth, thrown at the bottom of the inclined scraper under the action of inertia,...

Abstract

The invention discloses a double-screen-roller discharging mechanism. A discharging port is formed in the top of a discharging bin, wherein a first screen roller and a second screen roller are arranged at the discharging port, a roller body of the first screen roller and a roller body of the second screen roller are provided with roller teeth at intervals, screening gaps are formed among the roller teeth, the first screen roller and the second screen roller are arranged side by side, the positions of the roller teeth of the first screen roller are arranged corresponding to the positions of thescreening gaps of the second screen roller, the first screen roller and the second screen roller rotate inwards at the same time, the lower portion of the first screen roller and the lower portion ofthe second screen roller are both provided with material scraping plates, material scraping teeth are arranged at the free ends of the material scraping plates, and the material scraping teeth are inserted into the screening gaps of the first screen roller and the screening gaps of the second screen roller correspondingly. The mechanism has the advantages that the structure is reasonable, the discharging effect is good, and accumulated materials are easy to clean.

Description

Technical field [0001] The invention relates to a double-screen roller blanking mechanism, belonging to the technical field of material crushing machinery. Background technique [0002] As a device that breaks down fixed materials into granular materials, crushers are widely used in coal, ore and other industries. [0003] At present, the screen roll of the existing crusher screen roll blanking structure is cut through the gap between the screen rolls. Because the screen roll has a smooth surface structure, the force of the strip is small. The material in the gap will have the problem that it cannot be blanked, which will affect the effect of the crushed material blanking and increase the cost of manual cleaning. Summary of the invention [0004] Purpose: In order to overcome the shortcomings in the prior art, the present invention provides a double-screen roller blanking mechanism. [0005] Technical solution: In order to solve the above technical problems, the technical solution a...
