Description

Technical Field

[0001] This utility model belongs to the field of port production technology, and specifically relates to an electric gate valve device applied to an air cushion belt conveyor. Background Technology

[0002] Equipment used in bulk grain handling processes must have good waterproof sealing, and the gate valves used in air cushion conveyor belts must also have good airtightness. Therefore, the gate valves on air cushion conveyor belts must possess excellent airtightness. Existing gate valves are typically operated with two doors: one electrically or manually operated to open and close to meet feeding requirements, and the other equipped with a sealing cover for rain and air leakage prevention. Switching between these two doors requires manual operation, reducing equipment safety and increasing the workload of operators. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a reasonably designed electric gate valve device that can satisfy both feeding and waterproof / air-proof functions, addressing the shortcomings of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An electric gate valve device for an air cushion belt conveyor is characterized in that the device is located at the feed inlet of the air cushion belt conveyor and includes a gate for covering the feed inlet. Side baffles are symmetrically provided at the feed inlets on the left and right sides of the gate. The gate is located between the two side baffles. A plurality of guide rail wheels for supporting the gate are installed on the inner wall of the side baffles. The plurality of guide rail wheels on each side baffle are arranged side by side. A front baffle is provided at the feed inlet on the front side of the gate, and a drive mechanism for driving the gate to move horizontally is provided at the feed inlet on the rear side of the gate.

[0006] The drive mechanism includes a gear located below the gate and a rack that meshes with the gear. The rack is fixed to the bottom of the gate. The gear is connected to a bearing located on the side baffle via a gear axle. The gear axle is connected to a drive motor located on the outside of the side baffle.

[0007] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the driving mechanism is provided in two sets, which are located at the bottom of the gate to ensure the pushing force on the gate and avoid the force being too small to push it.

[0008] The technical problem to be solved by this utility model can also be achieved through the following technical solution: a cover plate is provided on the top of both the side baffle and the front baffle, and a sealing gasket that cooperates with the cover plate is provided around the gate plate to further improve the waterproof and air-leakage function of the gate plate.

[0009] The technical problem to be solved by this utility model can also be achieved through the following technical solution: a fixing block is installed on the inner side of the front baffle, and the fixing block is provided with a ramp to lift the gate. The lowest point of the ramp is flush with the top of the guide wheel. By raising the gate to a certain height, the sealing gasket on the gate and the cover plate are properly matched to avoid air leakage. If the gate is not raised to a certain height, the airtightness between the gate and the cover plate will be poor.

[0010] Compared with the prior art, this utility model uses a gate to seal the feed inlet of the air cushion belt conveyor, which can satisfy both feeding and waterproofing and air leakage prevention functions; the side baffle and front baffle make the fit between the gate and the feed inlet tighter; the drive mechanism realizes the automatic opening and closing of the gate; and the cover plate and sealing gasket further improve the sealing performance of the feed inlet.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Reference Figure 1-5 An electric gate valve device for use in an air cushion belt conveyor is provided. The device is located at the feed inlet 2 of the air cushion belt conveyor 1 and includes a gate plate 3 for covering the feed inlet 2. The gate plate is a horizontally arranged flat plate. Side baffles 4 are symmetrically arranged at the feed inlets on the left and right sides of the gate plate 3. The gate plate 3 is located between the two side baffles 4. Several guide rail wheels 5 for supporting the gate plate are installed on the inner wall of the side baffles 4. Several guide rail wheels 5 on each side baffle 4 are arranged side by side. A front baffle 10 is provided at the feed inlet 2 on the front side of the gate plate 3. A drive mechanism for driving the gate plate to move horizontally is provided at the feed inlet 2 on the rear side of the gate plate 4.

[0020] The drive mechanism includes a gear 8 located below the gate plate 3 and a rack 7 that meshes with the gear 8. The rack 7 is fixed to the bottom of the gate plate 3. The gear 8 is connected to a bearing located on the side baffle 4 via a wheel axle 11. The wheel axle 11 of the gear 8 is connected to a drive motor 6 located on the outside of the side baffle 4. The drive mechanism has two sets located at the bottom of the gate plate 3. The gears of the two sets of drive mechanisms can share a single wheel axle to avoid increasing the driving intensity due to an excessively large gate plate area.

[0021] Both the side baffle 4 and the front baffle 10 are provided with a cover plate. The cover plate is U-shaped at the top of the feed inlet, with the U-shaped opening facing the drive mechanism. Sealing gaskets that cooperate with the cover plate are provided around the gate plate 3, which further improves the waterproof and air-leakage prevention performance.

[0022] A fixing block is installed on the inner side of the front baffle. The fixing block has a ramp that lifts the gate. The lowest point of the ramp is flush with the top of the guide wheel, which further improves the waterproof and air-proof performance. The highest point of the ramp should not affect the engagement of the gear and rack. The setting is made according to the usage.

[0023] During operation, the drive motor 6 is started. Guided by the two side baffles 4 and supported by the guide wheels 5, the gate 3 moves forward along the side baffles 4. When it approaches the fixed block, the ramp 9 on the fixed block guides the gate 3 upward a certain distance, causing a sealing fit between the top of the gate 3 and the cover plate through a sealing gasket, thus sealing the inlet of the air cushion conveyor. Conversely, it moves backward until the inlet is fully opened. The length of the side baffles is at least twice the length of the inlet (referring to the length of the left side), and the two side baffles form the guide groove of the gate.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
