Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a large-scale rotary automatic feeder for mining. Background Technology

[0002] Feeders are key pieces of equipment widely used in various industries. Their main function is to continuously transport processed or unprocessed materials from one point to receiving equipment or transport machinery. Therefore, they are important equipment for many industries to achieve automated assembly line operations.

[0003] In mining operations, extra-large feeders are frequently used for ore transport. Heavy-duty plate feeders are often used when dealing with large ores. During operation, many hard, large ores will collide and rub against the feeder. This contact can damage the feeder and reduce its service life. Existing heavy-duty plate feeders lack a special impact-resistant and pressure-resistant structural design. Therefore, feeders need to be improved to address these issues. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a large-scale rotary automatic feeder for mining.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A mining extra-large rotary automatic feeder includes a frame, a conveyor chain, a drive device, and a baffle. The conveyor chain includes a chain body and a connecting assembly. The chain body includes a strength layer and a pressure-distributing layer. The strength layer wraps around the pressure-distributing layer. The strength layer is made of bimetallic composite wear-resistant steel plate. This material has high strength and its internal carbides are distributed in a fibrous manner, thus exhibiting excellent wear resistance, impact resistance, and corrosion resistance. The pressure-distributing layer is made of mesh-like high-molecular-weight polyethylene, which can effectively disperse and absorb the impact force, thereby further enhancing the impact resistance of the conveyor chain. The connecting assembly includes connecting holes and connecting rods. The connecting holes are located at the front and rear ends of both sides of the chain body. The two connecting holes are on the same horizontal line. The connecting holes penetrate the strength layer. The connecting rods are cylindrical and pass through the connecting holes. Both ends of the connecting rods are fixedly connected to the drive device.

[0006] Preferably, the frame includes a fixed base and a tripod. The tripod is disposed on both sides of the drive device. A crossbeam is provided in the middle of the tripod. The two ends of the crossbeam are fixedly connected to the two sides of the tripod. The two ends of the central shaft of the auxiliary wheel are fixedly connected to the crossbeam. A cylinder is fixedly connected between the apex corners of the two tripods. The fixed base is fixedly connected to the bottom of the tripod. The fixed base is disposed on both sides of the bottom edge of the tripod. The fixed base and the horizontal ground form a triangle. Both the fixed base and the bottom of the tripod are in contact with the ground.

[0007] Preferably, the baffle includes a baffle body and a reinforcing column. The baffle body is located above the driving device. Two baffle bodies are fixedly connected to the side of the frame near the driving device. The reinforcing column is fixedly connected to one side of the baffle body, and one end of the reinforcing column is fixedly connected to the frame.

[0008] Preferably, the driving device includes a drive wheel, a transmission chain, and an auxiliary wheel. The transmission chain is an industrial-grade chain, and the transmission chains are connected end to end. The cylinder at the connection point of each transmission chain is fixedly connected to a connecting rod to form a complete new cylinder. The drive wheel is a heavy-duty plate feeder-specific drive sprocket and is matched with the transmission chain. There are two drive wheels, respectively located at both ends of the loop formed by the transmission chain. The auxiliary wheel is a heavy-duty plate feeder-specific drive sprocket located between the two drive wheels to assist the drive wheels in their operation. Both the drive wheel and the auxiliary wheel mesh with the transmission chain.

[0009] Preferably, both the baffle and the frame are made of bimetallic composite wear-resistant steel plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the strength layer made of bimetallic composite wear-resistant steel plate gives the conveyor chain plate superior impact and wear resistance. Combined with the stress-dispersing layer, the conveyor chain plate is fully suitable for coping with the impact and wear of ore mining. The connecting rod runs through the conveyor chain plate and is fixedly connected to the transmission chain, which makes the conveyor chain plate more stable and firm, and has better impact and pressure resistance.

A cylinder 122 is fixedly connected between the apex corners of the two triangular frames 120. The fixed base 110 is fixedly connected to the bottom of the triangular frame 120. The fixed base 110 is located on both sides of the bottom edge of the triangular frame 120. The fixed base 110 forms a triangle with the horizontal ground. The fixed base 110 and the triangular frame 120 form a triangle. The bottom ends of all 20 are in contact with the ground, and the stability of the triangle allows the entire device to be stably placed on the ground. The driving device 3 includes a driving wheel 310, a transmission chain 320, and an auxiliary wheel 330. The transmission chain 320 is an industrial-grade chain, and the transmission chains 320 are connected end to end. A transmission chain 320 is fixedly connected to both sides of the conveyor chain plate 2. The driving wheel 310 is a special driving sprocket for heavy-duty plate feeders and is matched with the transmission chain 320. There are two driving wheels 310, which are respectively located at both ends of the loop formed by the transmission chains 320. The auxiliary wheel 330 is a special driving sprocket for heavy-duty plate feeders and is located between the two driving wheels 310 to assist the driving wheels 310 in their operation. Both the driving wheel 310 and the auxiliary wheel 330 are engaged with the transmission chain 320.

[0018] The baffle 4 includes a baffle body 410 and a reinforcing column 420. The baffle body 410 is located above the driving device 3.

[0019] like Figure 2 , Figure 3 and Figure 4 As shown, the conveyor chain 2 includes a chain body 210 and a connecting assembly 220. The chain body 210 includes a strength layer 211 and a pressure-distributing layer 212. The strength layer 211 encloses the pressure-distributing layer 212. The strength layer 211 is made of bimetallic composite wear-resistant steel plate. This material has high strength and its internal carbides are distributed in a fibrous manner, thus exhibiting excellent wear resistance, impact resistance, and corrosion resistance. The pressure-distributing layer 212 is made of mesh-like high-molecular-weight polyethylene, which can effectively disperse and absorb the impact force, thereby further enhancing the impact resistance of the conveyor chain 2. The connecting assembly 220... Component 220 includes a connecting hole 221 and a connecting rod 222. The connecting hole 221 is located at the front and rear ends of both sides of the chain plate body 210. The two connecting holes 221 are on the same horizontal line.

[0020] In use, the multiple conveyor chain plates 2 are connected into a loop by the transmission chain 320. The loop composed of the conveyor chain plates 2 is placed under the stone. The strength layer 211 made of bimetallic composite wear-resistant steel plate has excellent impact resistance and wear resistance. The pressure-distributing layer 212 composed of mesh polyethylene can effectively disperse the impact force and pressure on the conveyor chain plates 2. The frame 1 fixedly connected to both sides of the drive device 3 relies on the stability of the triangle to make the support device 5 stand stably on the ground. The connecting rod 222 passes through the conveyor chain plate 2 and is fixedly connected to the transmission chain 320. This makes the conveyor chain plate 2 more solid and stable, thereby further improving the impact and pressure resistance of the feeder. Example 2
