Description

Technical Field

[0001] The invention relates to a discharger in chemical equipment, in particular to a grading plough type discharger. Background Art

[0002] At present, the electro-hydraulic plow type unloader uses an electric hydraulic push rod as the power source. When working, the push rod extends to drive the frame forward, completes the fall of the plow blade, and the parallel roller group is propped up to form a working plane. The lower edge of the plow blade fits tightly with the conveyor belt. When unloading is completed, the push rod retracts to drive the frame backward, the plow blade is lifted, and the variable groove angle roller group restores the working surface from parallel to groove state, allowing the material to pass smoothly. Since the electric hydraulic push rod adopts hydraulic transmission, it has automatic overload protection performance. When the operation is blocked, the pressure in the oil circuit increases to the set limit, and the overflow device overflows accurately to implement overload protection.

[0003] In the existing technology, the plow type unloader has greatly reduced the workload of workers, but in the actual application process, A.: The plow type unloader adopts a single-sided single-stage plow. When the production is adjusted to close to the upper limit of production capacity, the amount of material on the conveyor belt increases, and the single-sided single-stage unloading cannot meet the unloading requirements, causing a large amount of material to spill out from the outside of the plow head, and even cross the plow, affecting normal production; B. The plow head of the plow type unloader is installed vertically, and the plow is installed on the front of the plow head working surface. During unloading, the material is easily blocked and piled up, causing the material to spill out from the outside of the plow head, causing dust pollution and waste. Summary of the invention

[0004] In view of this, the main purpose of the present invention is to provide a graded plow type discharger. Through the technical scheme, with the cooperation of the dolphin mouth plowshare, the guide plowshare, the side leakage prevention baffle and the anti-deflection baffle, the material is diverted to the maximum extent, and most of the material is intercepted and sent to the silo by the secondary plowshare and the tertiary plowshare. The granular material that leaks into the sealed channel formed by the blowing plowshare and the tertiary plowshare and the powder material that falls from the granular material are all blown into the silo, thereby effectively preventing material overflow and greatly improving work efficiency.
