Description

Technical Field

[0001] The utility model relates to the technical field of grain conveying equipment, in particular to a belt conveyor multi-point unloading device for grain conveying. Background Art

[0002] In the field of material transportation, belt conveyors, as an important transportation equipment, are widely used in coal, ore, building materials, chemical industry and other industries. However, the traditional belt conveyor has a single unloading point (usually unloading at the head), which limits its application scope and transportation efficiency to a certain extent. Therefore, the development of a multi-point unloader that can improve the conveying efficiency and cause less damage to the belt has become a technical problem that needs to be solved in the current field of material transportation.

[0003] Traditional belt conveyors usually use a single unloading point at the head, which has obvious limitations in the material transportation process. On the one hand, traditional belt conveyors cannot achieve intermediate unloading, and the equipment utilization rate is low; on the other hand, to achieve multi-point unloading, additional equipment is required, which increases investment.

[0004] In order to solve the above problems, some improved traditional belt conveyors have added intermediate dischargers, such as plow dischargers and discharge carts. Although these dischargers can achieve intermediate discharge to a certain extent, they have the problem of incomplete discharge and great damage to the belt. For example, during the discharge process of the plow discharger, the friction between the plow blade and the belt can easily cause the belt to wear and tear, affecting the normal operation of the conveyor belt. Utility Model Content

[0005] In order to solve the above problems, an embodiment of the utility model provides a multi-point unloading device that can improve the conveying efficiency (complete unloading) without causing damage to the belt.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a multi-point unloading device for a belt conveyor, comprising a shell, the upper part of the shell is provided with a feed port, the lower part is provided with a discharge channel, both sides of the discharge channel are provided with discharge ports, and a unloading module for changing the material conveying direction is provided between the feed port and the discharge channel;

[0007] The unloading module comprises a feed extension plate located at the upper part of the discharge channel, a rotating shaft is arranged at the upper part of the feed extension plate, a unloading flap for controlling the material conveying direction is fixedly mounted on the rotating shaft, and a driving device for driving the unloading flap to rotate is arranged outside the shell;

[0008] There are two feed extension plates, which are symmetrically distributed with the center line of the discharge channel as the axis, and a discharge flap is arranged on the top of each feed extension plate.

[0009] As a further improvement of the above technical solution:

[0010] The driving device comprises a cylinder and a crank arm connecting rod, one end of the crank arm connecting rod is connected to the telescopic end of the cylinder, and the other end is connected to the rotating shaft.

[0011] A receiving hopper is arranged in the feed port, and a transfer belt for raising the material conveying height is arranged on one side of the receiving hopper.

[0012] A reversing roller for changing the conveying direction of the transfer belt is arranged in the shell.

[0013] The beneficial effects of the embodiments of the utility model are as follows: 1. The multi-point unloading device for the belt conveyor comprises a shell, the upper part of the shell is provided with a feed port, the lower part is provided with a discharge channel, both sides of the discharge channel are provided with discharge ports, and a unloading module for changing the material conveying direction is provided between the feed port and the discharge channel. Through the unloading module, the conveying direction of the material is changed, and the material is conveyed to the discharge channel or the discharge port, so that the material can be reversed. Moreover, the unloading module is located between the feed port and the discharge channel, and is not in direct contact with the conveying belt, so that the belt will not be scratched during the reversing operation.

[0014] 2. Through the design of the unloading module and the coordination of the two discharge ports, the materials can be divided from the two discharge ports, which can improve the conveying speed after the material is reversed. Compared with the plow type unloader, there will be no material accumulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

Through the unloading module, the material conveying direction is changed, and the material is conveyed to the discharge channel 3 or the discharge port 12, so that the material reversing operation can be realized. Moreover, the unloading module is located between the feed port 2 and the discharge channel 3, and is not in direct contact with the conveying belt, so there will be no scratching of the belt during the reversing operation.

[0023] The unloading module includes a feed extension plate 4 located at the upper part of the discharge channel 3, a rotating shaft 5 is provided at the upper part of the feed extension plate 4, a unloading flap 6 for controlling the material conveying direction is fixedly mounted on the rotating shaft 5, and a driving device for driving the unloading flap 6 to rotate is provided outside the housing 1, and the driving device is used to change the rotation direction of the unloading flap 6, such as Figure 4 As shown, when the upper end of the discharge flap 5 is in contact with the inner wall of the shell, it is in the first working state. A Z-shaped sealing plate 13 is installed on the inner wall of the shell to prevent material leakage. At this time, the material falls from the discharge channel 3 to the conveyor belt for further transportation. When the driving device drives the discharge flap 6 to rotate and enters the second working state, as shown in FIG. Figure 5 As shown, the two discharge flaps 6 are flipped inward to form an inverted V-shaped dividing plate, which separates the materials and drops them into the discharge ports 12 on both sides. A V-shaped sealing plate 14 is installed in the shell 1 above the two discharge flaps 6 to prevent the materials from accumulating between the two discharge flaps 6 when falling.

[0024] There are two feed extension plates 4 , which are symmetrically distributed with the center line of the discharge channel 3 as the axis. A discharge flap 6 is disposed on the top of each feed extension plate 4 .

[0026] A receiving hopper 9 is provided in the feed port 2, and a transfer belt 10 for raising the material conveying height is provided on one side of the receiving hopper 9. The design of the transfer belt 10 can raise the material discharge height, which is convenient for the material separation operation of the equipment.

[0027] A reversing roller 11 for changing the conveying direction of the transfer belt 10 is provided in the shell 1. The conveying direction of the transfer belt 10 can be changed through the design of the reversing roller 11, and the structure is simple and easy to install.
