Description

Technical Field

[0001] The present invention relates to the field of conveyors, and particularly to a sealed bucket conveyor. Background Art

[0002] A bucket conveyor is a device used for vertically or obliquely conveying bulk materials. The sealed bucket conveyor is designed specifically for dust-proof, moisture-proof, and leakage-proof scenarios. It adopts a fully enclosed housing and a multi-layer sealing structure (such as silicone pads, labyrinth seals), and is suitable for industries with high cleanliness requirements such as food, medicine, and chemicals. Its hoppers and channels are made of stainless steel or food-grade polymers, which are corrosion-resistant and easy to disinfect. The materials are vertically lifted in a closed environment to avoid external contamination and dust spillage. An air lock valve or a flexible connection is configured at the discharge port to ensure no leakage throughout the process.

[0003] Existing non-fully sealed conveyor models are prone to dust leakage (especially when conveying fine powder materials), polluting the environment and posing an explosion risk. Moreover, there is a gap between the conveyor belt inside the conveyor and the housing, and materials will leak from the gap during material conveyance, resulting in material waste and the occurrence of cross-contamination between multiple materials. Summary of the Invention

[0004] In view of this, the present invention provides a sealed bucket conveyor. The main technical problem to be solved is: to provide a sealed bucket conveyor that reduces the contact between materials and the outside world and at the same time avoids material leakage from the side of the conveyor belt.

[0005] To achieve the above object, the present invention adopts the following technical scheme: A sealed bucket conveyor includes a main body. A conveying mechanism is installed inside the main body. The main body includes a housing. A first inner cavity is opened inside the housing, and a second inner cavity is opened inside the housing. The conveying mechanism includes chains. The number of the chains is two. A fixing plate is fixedly connected between the two chains, and the number of the fixing plates is multiple. A conveyor belt is fixedly connected to the outside of the fixing plate. The chains are located inside the first inner cavity, and the conveyor belt is located inside the second inner cavity. A protective belt is fixedly connected to the surface of the conveyor belt, and the structure of the protective belt is a wavy structure.

[0006] By adopting the above technical scheme, the conveying mechanism moves inside the main body to convey materials. The wavy protective belt at the edge of the conveyor belt can block and seal the side of the conveyor belt, avoiding material leakage from the side of the conveyor belt. At the same time, the top of the wavy protective belt can expand when encountering a turn. Compared with a straight protective belt, when encountering a turn, the top of the straight protective belt needs to move a greater distance, resulting in the top being easily pulled and broken. The wavy protective belt can be applied to conveyors with multiple turning points.

[0007] As a further description of the above technical scheme:

[0008] A motor is fixedly connected to the outer surface of the head of the housing. The output end of the motor is fixedly connected to a rotating shaft, and the end of the rotating shaft away from the motor is movably connected to the inner surface of the housing.

[0009] By adopting the above technical solution, the motor can drive the conveying mechanism to move at the head of the housing. The motor can work to drive the rotating shaft to rotate, facilitating the movement of the chain inside the housing.

[0010] As a further description of the above technical solution:

[0011] The outer surface of the rotating shaft is orbitally connected with driving wheels. The number of the driving wheels is two, and the two chains are respectively installed on the two driving wheels.

[0012] By adopting the above technical solution, the motor drives the rotating shaft to rotate and then drives the driving wheels to rotate. The rotation of the driving wheels can drive the chain to move, facilitating the movement of the conveyor belt inside the housing.

[0013] As a further description of the above technical solution:

[0014] A connecting bolt is installed inside the chain. A roller is installed on the connecting bolt, and the roller is located inside the chain.

[0015] By adopting the above technical solution, the roller can assist the chain to rotate inside the housing.

[0016] As a further description of the above technical solution:

[0017] The inner wall of the first inner cavity is fixedly connected with guide rails. The number of the guide rails is four, and the outer surface of the guide rails is in contact with the outer surface of the roller.

[0018] By adopting the above technical solution, the guide rails and the inner wall of the first inner cavity can limit the roller, facilitating the movement of the conveying mechanism inside the main body.

[0019] As a further description of the above technical solution:

[0020] The surface of the connecting bolt is threadedly connected with a nut. A through hole is opened inside the connecting bolt, and a fixing pin is installed inside the through hole.

[0021] By adopting the above technical solution, it is convenient for the connecting bolt to fix the chain.

[0022] As a further description of the above technical solution:

[0023] The number of the protective belts is two, and the two protective belts are respectively located on the left and right sides of the conveyor belt.

[0024] By adopting the above technical solution, two protective belts can block both ends of the conveyor belt, enhancing the sealing effect of the conveyor belt.

[0025] By means of the above technical solution, a sealed bucket conveyor of the present invention has at least the following beneficial effects:

[0026] 1. Compared with the prior art, for this sealed bucket conveyor, the wavy protective belt at the edge of the conveyor belt can block and seal the side of the conveyor belt, preventing materials from leaking from the side of the conveyor belt. At the same time, when the wavy protective belt encounters a turn, its top can expand (since the protective belt is on the conveyor belt, when encountering a turn, the turning radius of the top of the protective belt is larger and it needs to move a greater distance. The top of the wavy protective belt is relatively loose and can expand to block the materials). Compared with a straight protective belt, when encountering a turn, the top of the straight protective belt needs to move a greater distance, resulting in the top being easily pulled and broken. The wavy protective belt can be applied to conveyors with multiple turning points.

[0027] 2. Compared with the prior art, for this sealed bucket conveyor, through the guide rail and the inner wall of the first inner cavity, the roller can be limited, enabling the chain to move between the guide rail and the inner wall of the first inner cavity, facilitating the movement of the conveying mechanism within the main body.

[0035] Referring toFigures 1-5 , a sealed bucket conveyor provided by the present invention: including a main body 1, a conveying mechanism 2 is installed inside the main body 1, and the conveying mechanism 2 moves inside the main body 1 to convey materials. The main body 1 includes a housing 101, a first inner cavity 102 is opened inside the housing 101, and a second inner cavity 103 is opened inside the housing 101. The first inner cavity 102 and the second inner cavity 103 are combined to form a cross-shaped inner cavity. The conveying mechanism 2 includes a chain 201. The number of chains 201 is two. A fixing plate 204 is fixedly connected between the two chains 201, and the number of fixing plates 204 is multiple. A conveyor belt 205 is fixedly connected to the outside of the fixing plate 204. The chain 201 is located inside the first inner cavity 102, and the chain 201 moves inside the first inner cavity 102. The conveyor belt 205 is located inside the second inner cavity 103, and the conveyor belt 205 moves inside the second inner cavity 103. A protective belt 206 is fixedly connected to the surface of the conveyor belt 205. The structure of the protective belt 206 is a wavy structure. The number of protective belts 206 is two. The two protective belts 206 are respectively located on the left and right sides of the conveyor belt 205. The two protective belts 206 can block the two ends of the conveyor belt 205, increasing the sealing effect of the conveyor belt 205. The wavy protective belt 206 at the edge of the conveyor belt 205 can block and seal the side of the conveyor belt 205, preventing materials from leaking from the side of the conveyor belt 205. At the same time, the top of the wavy protective belt 206 can expand when turning. Since the protective belt 206 is on the conveyor belt 205, when turning, the turning radius of the top of the protective belt 206 is larger and more distance needs to be moved. The top of the wavy protective belt is relatively loose and can expand to block materials. Compared with a straight protective belt, when turning, the top needs to move a greater distance, resulting in the top being easily pulled and broken. The wavy protective belt 206 can be applied to conveyors with multiple turning points.

[0036] A motor 104 is fixedly connected to the outer surface of the head of the housing 101. The motor 104 can be installed on the top or side of the end of the housing 101. The output end of the motor 104 is fixedly connected to a rotating shaft 105. The end of the rotating shaft 105 away from the motor 104 is movably connected to the inner surface of the housing 101. The motor 104 can drive the conveying mechanism 2 to move at the head of the housing 101. By the operation of the motor 104, the rotating shaft 105 can be driven to rotate, facilitating the movement of the chain 201 inside the housing 101. A driving wheel 106 is connected to the outer surface of the rotating shaft 105 in an orbital manner. The number of driving wheels 106 is two, one above and one below. The two chains 201 are respectively installed on the two driving wheels 106. The motor 104 drives the rotating shaft 105 to rotate, and then drives the driving wheel 106 to rotate. By the rotation of the driving wheel 106, the chain 201 can be driven to move, facilitating the movement of the conveyor belt 205 inside the housing 101.

[0037] Inside the chain 201, a connecting bolt 202 is installed. A roller 203 is installed on the connecting bolt 202, and the roller 203 is located inside the chain 201. The roller 203 can assist the chain 201 to rotate inside the housing 101. The inner wall of the first inner cavity 102 is fixedly connected with guide rails 107. The number of guide rails 107 is four. The outer surface of the guide rail 107 is in contact with the outer surface of the roller 203. The guide rail 107 and the inner wall of the first inner cavity 102 can limit the roller 203, facilitating the movement of the conveying mechanism 2 inside the main body 1.

[0038] A nut is threadedly connected to the surface of the connecting bolt 202. A through hole is opened inside the connecting bolt 202, and a fixing pin is installed inside the through hole, facilitating the fixing of the chain 201 by the connecting bolt 202.

[0039] Working principle: During use, the wavy protective belt 206 at the edge of the conveyor belt 205 can block and seal the side of the conveyor belt 205, preventing materials from leaking from the side of the conveyor belt 205. At the same time, the top of the wavy protective belt 206 can expand when encountering a turn. Since the protective belt 206 is on the conveyor belt 205, when encountering a turn, the turning radius of the top of the protective belt 206 will be larger and more distance needs to be moved. The top of the wavy protective belt is relatively loose and can expand to block the materials. Compared with a straight protective belt, when encountering a turn, the top of the straight protective belt needs to move a greater distance, resulting in the top being easily pulled and broken. The wavy protective belt 206 can be applied to conveyors with multiple turning points.
