Description

Technical Field

[0001] This utility model relates to the field of material discharge technology, specifically to a storage tank discharge port that is easy to unclog. Background Technology

[0002] Currently, tobacco storage bins widely used in domestic and international markets and by various tobacco companies typically employ a traditional sealed side baffle design. The front and rear outlet baffles of these bins are trapezoidal planes with flat bottoms, resulting in limited effective discharge space. In actual production, if the amount of tobacco discharged from the bin to the next-stage belt conveyor precisely meets the tobacco demand of the mixing machine, material blockage will not occur. However, to ensure saturated tobacco intake and meet the buffering requirements during sequential equipment startup, the actual tobacco supply often exceeds the demand, leading to uneven material layer thickness at the outlet. This is particularly pronounced when there are many tobacco intake pipes, exacerbating material blockage at the outlet.

[0003] When the feed inlet of the storage tank becomes blocked, the unblocking process is difficult, time-consuming, and poses significant safety hazards, severely reducing production efficiency. Furthermore, the prolonged residence time of tobacco during transport can lead to moisture loss, affecting the quality of the cigarette product and adversely impacting the stability of the final product. To address these issues, this invention proposes an easily unblockable feed inlet for the storage tank, facilitating unblocking when blockages occur. Utility Model Content

[0004] The purpose of this utility model is to provide a storage tank discharge port that is easy to unclog, so that the discharge port can be easily unclogged when blockage occurs.

The discharge trough body is disposed along the length direction of the conveyor belt conveying surface. The discharge trough body is formed by two end plate assemblies and two side plate assemblies.

[0007] The end plate assembly includes an end plate body and a flexible splash guard. The end plate body has a discharge notch, and the flexible splash guard is installed on the discharge notch.

[0008] The side panel assembly includes a fixed side strip and a movable side panel. The fixed side strip is connected between two end plate bodies, and the movable side panel is movably connected to the fixed side strip.

[0009] Furthermore, the upper edge of the discharge notch is arc-shaped, the flexible splash guard is made of flexible rubber, and the flexible rubber is cut at intervals to form baffles.

[0010] Furthermore, the fixed side strip is provided with a hinge, and a movable side plate is connected to the hinge. A side plate reinforcing rib is also provided on the side of the movable side plate.

[0011] Furthermore, the movable side plate is provided with latch-type clamps at both ends. When the latch-type clamps are connected to the end plate body, the movable side plate and the end plate body are in a closed state.

[0012] Furthermore, a flexible side panel curtain is provided at the bottom of the movable side panel, and the flexible side panel curtain is made of flexible rubber material.

[0013] Furthermore, the movable side panel has a transparent plate structure.
