[0002] In large enterprises such as metallurgy, chemical industry, building materials, docks, thermal power plants, etc., it is often necessary to transport raw materials from mines or ports to conveyor belts through transfer stations for subsequent packaging and processing.

[0003] The design structure of the existing transfer station is upper and lower belt transportation. The upper level adopts a double-way belt, one of which is the main operation and the other is a backup; the lower level adopts a three-way belt for packaging. At the head funnel of the double-way belt of the upper level, the electric tee and the coal drop pipe are installed to realize the material distribution of the three-way belt below. However, this solution requires the setting of a certain height of inclined self-sliding slope, so that the material is transported downward along the top of the slope under the action of gravity. During this period, the material is easy to raise a lot of dust, and the impact on the conveying equipment is relatively large, resulting in faster wear of equipment components such as conveying pipelines, higher maintenance frequency, and greater difficulty in maintenance. While affecting the stability and continuous operation capability of the system, the transfer station has a high floor height, which greatly increases the construction cost of civil engineering.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0027] like Figure 1-Figure 4 As shown, in one embodiment, a multi-point transfer and dropping device for a bulk material conveying and transfer station includes: a volumetric feeder 1 and a rotary switching mechanism 2.

[0028] The rotary switching mechanism 2 includes a slewing bearing 21 and a rotary wheel 22. The upper part of the volumetric feeder 1 is connected to the head hopper 41 of the belt conveyor 4 through the slewing bearing, and the lower part rotates on the circular track 3 through the rotary wheel 22 to switch to feeding one of the multiple belt conveyors 4 below. Specifically, the head hopper 41 is symmetrically arranged above the volumetric feeder 1; and the multiple belt conveyors 4 are equidistantly arranged at the bottom of the discharge port of the volumetric feeder 1.

[0029] Furthermore, the upper part of the slewing bearing 21 is connected to the head hopper 41 by flange bolts, and the lower part of the slewing bearing 21 is connected to the volumetric feeder 1 by flange bolts. The slewing bearing 21 is driven by a motor, the outer ring of the slewing bearing 21 is fixed, and the inner ring can rotate.

[0030] like Figure 1-Figure 4 As shown, in this embodiment, the volumetric feeder 1 and the travel wheel are connected by bolts to form a rotating whole, so that the volumetric feeder 1 can rotate around the feed port through the rotating wheel 22.

[0031] Furthermore, a feed port is provided on one side above the volumetric feeder 1, a discharge port is provided on the other side below the volumetric feeder 1, and a discharge pipe is provided inside the volumetric feeder 1. The discharge port is connected to a guide trough, and the material falls into the guide trough through the discharge pipe; the volumetric feeder 1 drives the rotor to perform feeding operation through a motor reducer assembly, and the speed can be adjusted by changing the speed by using a variable frequency motor. In addition, the volumetric feeder 1 is also equipped with an electronic control system to achieve remote and local control, providing a convenient operation method.

[0032] like Figure 1-Figure 4 As shown, in this embodiment, the annular track 3 is symmetrically fixed above the ground through the pillars 31 to guide the movement of the rotary wheel 22. The annular track 3 is made of track steel that is heated and bent into a circular ring shape, which has sufficient stability and load-bearing capacity.

[0033] Working principle: By operating the control box, first start the electric slewing support bearing 21, so that the volumetric feeder 1 rotates around the inlet as driven by the slewing bearing. During the rotation, the discharge port will rotate to the upper position of any belt conveyor 4 of the next level as the circular track 3 rotates; after reaching the specified position, the next level belt conveyor 4, the volumetric feeder 1 and the previous level belt conveyor 4 are started in sequence. In the working chamber of the volumetric feeder 1, the material is pushed to the position of the discharge pipe along the conveying direction, and the material falls into the guide trough through the discharge pipe, and then enters the conveying belt of the next level belt conveyor 4.

[0034] Through the above technical solution, the present application removes the electric tee and forked drop pipe under the head hopper 41 of the original belt conveyor 4, improves the vertical drop to horizontal feeding, installs an electric slewing support bearing 21 under the hopper, and installs a volumetric feeder 1 under the slewing support bearing 21, and installs a rotary wheel 22 under the feeder, and sets a circular track 3 under the feeder and the rotary wheel 22, and supports it above the ground with columns 31. The electric slewing support bearing 21 drives the volumetric feeder 1 to rotate on the track, so that any volumetric feeder 1 can feed any belt of the next-level belt conveyor 4 after receiving the material dropped from the head hopper 41 of the previous-level belt conveyor 4, which is convenient for subsequent maintenance and overhaul work, and effectively reduces the design height of the transfer station floor, thereby greatly saving civil construction costs.

[0035] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
