Description

Technical Field

[0001] This utility model relates to the technical field of port conveying devices, specifically to an electric rotating three-way device for bulk cargo chutes. Background Technology

[0002] In existing bulk cargo terminal conveyor tee structures, a flap mechanism is commonly used, with the material conveying direction changed by controlling an electric push rod to rotate the flap. This structure is simple and low-cost, but it has some obvious problems: First, the flap mechanism easily leads to material accumulation, especially at the tee, where material tends to pile up, affecting conveying efficiency. Second, in the low-temperature environment of northern winters, material freezes above the flap, preventing it from opening properly and causing damage to the electric push rod, ultimately requiring manual operation. This not only reduces production efficiency but also increases safety hazards.

[0003] Furthermore, the frequent use and damage of electric actuators increase maintenance costs and operational risks. Therefore, a new T-junction design is needed to avoid material accumulation and freezing problems while improving system reliability and safety. Utility Model Content

[0004] The purpose of this utility model is to provide an electric rotating tee device for bulk cargo chutes, in order to solve the problems mentioned in the background art, such as the easy accumulation and freezing of materials in the existing flap-type tee structure of bulk cargo terminal belt conveyors, which leads to damage to the electric push rod, reduced production efficiency, and increased safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric rotating tee device for bulk cargo chutes, comprising a horizontally arranged platform and a horizontally arranged mounting beam above it, a swing funnel being provided at the bottom of the mounting beam via a supporting steel structure, an arc-shaped bifurcated discharge guide plate being provided below the swing funnel on the platform, a variable amplitude mechanism being provided on the side of the platform, a limit detection device being provided at the bottom edge, and a locking device being provided on the platform.

Coaxial bearing seats are respectively provided on the sides of the two steel lifting lugs facing each other, and a swing funnel is provided through the two bearing seats.

[0009] Furthermore, the swinging funnel includes a funnel body that is conical in shape, wider at the top and narrower at the bottom. The top edge of the funnel body has two opposing, upward-protruding main body convex edges. A funnel swing shaft is coaxially arranged at the middle of the outer side of each of the two main body convex edges. The two funnel swing shafts are respectively matched and installed with two bearing seats. The bottom of the funnel body has an arc-shaped discharge port that matches the shape of the bifurcated discharge guide plate. A variable amplitude mechanism is connected to the side wall of the funnel body.

[0010] Furthermore, the bifurcated discharge guide plate is arc-shaped, and a guide plate discharge port larger than the discharge port of the swing funnel is provided on both sides of its lowest point.

[0011] Furthermore, the luffing mechanism includes a luffing support, and a hydraulic cylinder is provided between the luffing support and the funnel body. The two ends of the hydraulic cylinder are respectively hinged to the luffing support and the funnel body via a rotating shaft. The hydraulic cylinder is also connected to a hydraulic station provided on the platform.

[0012] Furthermore, the limiting detection device includes limiting detection baffles respectively set on both sides of the bottom edge of the funnel body at the highest point, and two sets of limiting detection baffles are respectively set to extend forward and backward on the same side of the funnel body, and the limiting detection baffles are set horizontally when they swing to the lowest point; the limiting detection baffles are provided with locking through holes.

[0013] Furthermore, the locking device includes two locking brackets respectively positioned below two steel lifting lugs on the platform. The locking brackets are C-shaped and have a locking cylinder at the top. The piston rod of the locking cylinder passes through the top plate of the locking bracket and is connected to a locking pin that can be inserted into the locking through hole.

[0014] Furthermore, the top of the oscillating funnel is provided with multiple dustproof skirts.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The use of this utility model eliminates the need for the electric flap of the original tee, so that the tee will not become unusable due to material freezing; and the resistance generated after freezing will not cause damage to the push rod or deformation of the structure.
