Description

Technical Field

[0001] This utility model relates to the field of grain and feed machinery technology, specifically to a novel multi-point discharge flap gate structure for scraper conveyors. Background Technology

[0002] The multi-point discharge flap gate of a scraper conveyor is a common industrial device, ideal for controlling the material leaving the scraper conveyor and entering the next process in a material conveying system. It plays a vital role in material conveying and processing, and is widely used in the distribution of solid granular and powdery materials in industries such as building materials, metallurgy, mining, light industry, and grain processing.

[0003] Currently, in the existing grain and feed machinery industry, a single conveyor scraper has multiple discharge and distribution points, requiring the installation of multi-point discharge gates. However, traditional multi-point discharge gates are mostly horizontal sliding gate structures, which suffer from problems such as large space occupation, untimely discharge, and material accumulation. A small number of multi-point discharge gates are flap gates, but their structure is unreasonable, with excessive power configuration, making it easy for the flap gate to jam. Therefore, there is an urgent need to design a flap gate structure that can avoid material accumulation at the gate and is less prone to flap gate failure due to jamming. Utility Model Content

[0004] The purpose of this invention is to address the problems of large space occupation, untimely material discharge, and material accumulation in existing horizontal sliding multi-point discharge gate structures, as well as the problem of easy jamming of gate flaps in existing multi-point discharge gate structures. A new type of scraper conveyor multi-point discharge flap gate structure has been designed, which can avoid material accumulation in the gate and prevent the gate from easily jamming and failing, thereby solving the above problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] The gate housing has a first direction and a second direction that are perpendicular to each other;

[0008] A flap assembly is hinged to the gate housing along a first direction;

[0009] A power system, located inside the gate housing, is used to drive the opening and closing of the flap assembly;

[0010] And an outer casing, which is disposed on the gate housing, for shielding the power system so that it is not exposed to the outside;

[0011] The power system includes the following structural configuration:

[0012] A mounted bearing is provided on the gate housing;

[0013] A crank, one end of which is rotatably mounted on the seated bearing;

[0014] A cylinder is mounted on the gate housing. The output end of the cylinder is rotatably connected to the other end of the crank to drive the crank to move. The crank then drives the flap assembly to open and close.

[0015] And a solenoid valve, which is disposed on the gate housing, is used to connect to an air source and supply air to the cylinder to drive the cylinder, and the cylinder drives the crank to move.

[0016] Specifically, the novel multi-point discharge flap gate structure for scraper conveyors designed in this utility model aims to solve the problem of multi-point discharge requirements in existing scraper conveyors and to address the issues of material accumulation and gate jamming that have existed in previous multi-point discharge gates. This novel multi-point discharge flap gate structure for scraper conveyors also allows the gate to be connected to a PLC for programmed control, achieving automated functions.

Two quick-installation pressure strips are added to the gate housing to achieve quick installation, regardless of the openings in the scraper conveyor bottom plate.

[0019] Furthermore, a novel multi-point discharge flap gate structure for scraper conveyors: the power system further includes a push rod, which is disposed on the crank along a second direction, and the push rod is used to drive the flap assembly to perform opening and closing actions.

[0020] Furthermore, a novel multi-point discharge flap gate structure for scraper conveyors includes the following structural configuration:

[0022] A crank-slider is disposed on the flap gate along a first direction;

[0023] And a gravity pull ring, which is set on the crank slider and has the freedom to swing, to ensure that the gravity pull ring always remains vertically downward under the action of gravity, and the push rod passes between the gravity pull ring and the crank slider.

[0024] Furthermore, a novel multi-point discharge flap gate structure for scraper conveyors includes a flap assembly that further comprises a rotating shaft arranged along a first direction, which is respectively arranged at opposite ends of the crank slider in the first direction; the gravity pull ring is configured as a U-shaped structure, with its two ends respectively rotatably arranged on the rotating shaft.

[0025] Furthermore, a novel multi-point discharge flap gate structure for scraper conveyors: the power system also includes a Y-type connector, one end of which is connected to the output end of the cylinder, and the other end is rotatably connected to the crank.

[0026] Furthermore, a novel multi-point discharge flap gate structure for scraper conveyors: the power system also includes an exhaust-type throttle valve, whose inlet and outlet are respectively connected to the solenoid valve and the cylinder.

[0027] Furthermore, a novel multi-point discharge flap gate structure for scraper conveyors includes a power system that further comprises a hydraulic buffer, which is located on both sides of the crank and is used to adjust the rotation angle of the crank and buffer the impact upon reaching the destination.

[0028] The beneficial effects of this utility model are:

[0029] This invention relates to a novel multi-point discharge flap gate structure for scraper conveyors. It improves upon existing flap gate power systems by adding a protective plate to the power system housing, using a cylinder to provide power for the flapping mechanism, and allowing for precise speed control via an exhaust-type throttle valve. Furthermore, this novel multi-point discharge flap gate structure incorporates a gate buffer control mechanism, which adjusts the relative position of the hydraulic buffer to achieve precise control over the opening and closing angle and force of the flap gate.

[0030] This utility model designs a novel multi-point discharge flap gate structure for scraper conveyors. It improves the flap assembly by adding a crank slider, making the flap gate open more smoothly and preventing the gate from jamming. It also adds a gravity pull ring, which can always remain vertically downward under the action of gravity and can maintain perpendicular contact with the crank, thereby ensuring that the crank is not jammed during rotation and solving the problem of flap gates easily jamming.

[0041] Example 1

[0042] like Figures 1-4 As shown in the figure, this embodiment 1 designs a novel multi-point discharge flap gate structure for scraper conveyors. The flap gate structure includes the following specific structural configurations:

[0043] The gate housing 1 has a first direction and a second direction that are perpendicular to each other;

[0044] The flap assembly 2 is hinged to the gate housing 1 along the first direction;

[0045] The power system 3 is located inside the gate housing 1 and is used to drive the opening and closing of the flap assembly 2;

[0046] The outer casing 4 is disposed on the gate housing 1;

[0047] And the mounting strip 5, which is installed on the gate housing 1;

[0048] The flip panel assembly 2 includes the following specific structural configuration:

[0049] A flap gate 21 is hinged to the gate housing 1 along a first direction;

[0050] A crank slider 22 is disposed on the flap gate 21 along the first direction, and a rotating shaft 24 is respectively disposed at opposite ends of the crank slider 22 in the first direction;

[0051] And a gravity pull ring 23, which is configured as a U-shaped structure. The two ends of the gravity pull ring 23 are respectively rotatably mounted on the rotating shaft 24. At this time, the gravity pull ring 23 has the freedom to swing, so as to ensure that the gravity pull ring 23 always remains vertically downward under the action of its own gravity.

[0052] The power system 3 includes the following specific structural configuration:

[0053] A seated bearing 31 is mounted on the gate housing 1;

[0054] A crank 32 is rotatably mounted on the bearing 31 with a seat. A push rod 35 is also connected to the crank 32. The push rod 35 is arranged along the second direction and passes between the gravity pull ring 23 and the crank slider 22. It is used to push the flap assembly 2 to open and close. Hydraulic buffers 38 are also provided on both sides of the crank 32. They are used to adjust the rotation angle of the crank 32 and buffer the impact when it is in position.

[0055] A cylinder 33 is mounted on the gate housing 1. The output end of the cylinder 33 is also connected to one end of a Y-type connector 36, and the other end of the Y-type connector 36 is rotatably connected to the other end of the crank 32. The cylinder 33 drives the crank 32 through the Y-type connector 36, and the push rod 35 on the crank 32 drives the flap assembly 2 to open and close.

[0056] Solenoid valve 34 is disposed on the gate housing 1. The outlet of solenoid valve 34 is also connected to the inlet of exhaust type throttle valve 37. The outlet of exhaust type throttle valve 37 is connected to cylinder 33. The inlet of solenoid valve 34 is used to connect to an air source and supply it to cylinder 33 through exhaust type throttle valve 37 to drive cylinder 33.

[0057] Specifically, in the novel scraper conveyor multi-point discharge flap gate structure designed in Embodiment 1 above, the power actuator is a cylinder 33. After the air source is connected to the solenoid valve 34, the operation of the solenoid valve 34 can be controlled by the PLC. Then, the air source is connected to the cylinder 33 through the exhaust-type throttle valve 37, causing the cylinder 33 to perform an action. The Y-type connector 36 drives the crank 32, which is mounted and fixed to the housing 1 by the bearing 31. Hydraulic buffers 38 are installed on both sides of the crank 32 to adjust the rotation angle of the crank 32 and buffer the impact when it reaches the position. After the power is transmitted to the crank 32, the push rod 35 on the crank 32 drives the flap assembly 2, thereby realizing the opening and closing of the gate flap.

[0058] Specifically, in the flap assembly 2, the crank-slider 22 is mounted on the flap gate 21, and the gravity pull ring 23 is mounted on the crank-slider 22. When the crank assembly 2 flips upward, the cylinder 33 transmits power to the crank-slider 22 through the crank 32 and the push rod 35, causing the flap gate 21 to flip upward and achieve the closing action. Conversely, when the crank assembly 2 flips downward, the cylinder 33 drives the push rod 35 to move back, at which time the push rod 35 will pull the gravity pull ring 23, causing the flap gate 21 to open.

[0059] The above-described preferred embodiments of this utility model are for illustrative purposes only and are not intended to limit the scope of this utility model. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
