Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor technology, and more specifically, to a scraper conveyor with anti-chain breakage capability. Background Technology

[0002] Scraper conveyors are one of the main transportation equipment in coal preparation plants. Sprocket jamming and chain skipping are common faults of scraper conveyors. Sprocket skipping can cause the two chains on the side of the scraper to become out of sync, which may lead to chain deformation and, in severe cases, chain breakage and damage to the equipment.

[0003] Chinese utility model patent application number 202422010784.8 discloses a chain protection device for a scraper conveyor. It has a monitoring point and a protection component at the bottom of the scraper, which can monitor in real time whether the chain breaks and can clamp the broken ends in time through the protection component to prevent the chain from falling. However, there is a certain distance between the protection components. Goods on the scraper between the two protection components may fall to the inside of the scraper conveyor, which may cause safety problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a scraper conveyor with higher safety and chain breakage prevention.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A scraper conveyor with anti-chain breakage capability includes a fixed frame that is inclined. A tensioning mechanism is installed at the bottom of the fixed frame. A power component is installed at the top of the fixed frame and at the output end of the tensioning mechanism. A roller is connected to the output shaft of the power component. A conveyor belt is tensioned together on two rollers. A plurality of hoppers are evenly arranged on the conveyor belt. An anti-chain breakage mechanism is connected between two adjacent hoppers. A discharge port is provided at the top of the fixed frame.

[0007] The present invention is further configured such that: the anti-breakage mechanism includes two connecting blocks and two connecting rods, the two connecting blocks are respectively fixed at both ends of the hopper, the two connecting rods are correspondingly arranged with the two connecting blocks, the connecting blocks have connecting grooves on the side away from the hopper, the two connecting grooves on the same side of two adjacent connecting blocks form a group, and the two ends of the connecting rod are provided with end posts, the two end posts on the same connecting rod are respectively slidably engaged with a group of connecting grooves.

[0008] The present invention is further configured such that: the tensioning mechanism includes two mounting plates, which are respectively disposed on both sides of the fixed frame; the two ends of the bottom roller shaft are rotatably connected to the two mounting plates respectively; the bottom of the fixed frame is provided with a plurality of sliders, which are slidably connected to the mounting plates; the bottom of the fixed frame is connected to a fixed plate; a screw is connected between the fixed plate and the mounting plate; a bolt abuts on both sides of the connection between the screw and the fixed plate; and a bolt abuts on both sides of the connection between the screw and the mounting plate.

[0009] The present invention is further configured such that: a pressure detector is provided on the bolt that abuts against the fixing plate, the pressure detector is located between the fixing plate and the bolt, and the pressure detector is electrically connected to an alarm.

[0010] The present invention is further configured such that: the cross-section of the hopper is trapezoidal, and one side of the long side of the trapezoid is the open side.

[0011] The present invention is further configured such that: a plurality of baffles are evenly arranged on both sides of the conveyor belt, the plurality of baffles are spaced apart, and the baffles extend toward one side of the hopper.

[0012] The present invention is further configured such that: a protective net is provided around the outside of the fixed frame, and the conveyor belt is inside the protective net.

[0013] The advantages of this utility model are:

[0014] 1. The scraper is set as a hopper. During transportation, the material is scooped into the hopper, reducing the probability of falling. At the same time, several baffles are set on both sides of the conveyor belt to prevent the material from falling between the conveyor belt and the power components, reducing the risk of damage to the conveyor belt.

[0015] 2. An anti-breakage mechanism is installed between two adjacent hoppers. The connecting rod is simultaneously slidably engaged with the connecting groove of the two adjacent hoppers through the end posts at both ends. When the conveyor belt breaks, the connecting rod can prevent the conveyor belt from falling off by pulling the two hoppers at the break point, thus avoiding the goods falling and improving safety.

[0016] 3. When the conveyor belt breaks, it is pulled together by the connecting rods on both sides. At this time, the overall length of the conveyor belt increases, which reduces the tension on the conveyor belt. The value on the pressure detector changes abruptly, triggering the alarm. This reminds the operator to carry out timely maintenance to ensure the overall safety of the scraper conveyor. Attached Figure Description

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A scraper conveyor with anti-chain breakage capability includes a fixed frame 1, which is inclined. A tensioning mechanism 3 is installed at the bottom of the fixed frame 1. A power component 2 is installed at the top of the fixed frame 1 and at the output end of the tensioning mechanism 3. A roller shaft is connected to the output shaft of the power component 2. A conveyor belt 4 is tensioned together on the two roller shafts. Several hoppers 5 are evenly arranged on the conveyor belt 4. The cross-section of the hopper 5 is trapezoidal, and the long side of the trapezoid of the hopper 5 is the open side. The hopper 5 can scoop up the material into the hopper, replacing the conventional scraper method of intercepting and pushing the material, reducing the risk of material falling. An anti-breakage mechanism 8 is connected between two adjacent hoppers 5. A discharge port 7 is provided at the top of the fixed frame 1.

[0028] The anti-breakage mechanism 8 includes two connecting blocks 81 and two connecting rods 83. The two connecting blocks 81 are fixed at both ends of the hopper 5, and the two connecting rods 83 are correspondingly arranged with the two connecting blocks 81. The connecting blocks 81 have connecting grooves 82 on the side away from the hopper 5. The two connecting grooves 82 on the same side of two adjacent connecting blocks 81 form a group. Both ends of the connecting rods 83 are provided with end posts 84. The two end posts 84 on the same connecting rod 83 are respectively slidably engaged with a group of connecting grooves 82.

[0029] When the conveyor belt 4 breaks, the two adjacent hoppers 5 move away from each other until the end posts 84 at both ends of the hoppers 5 are engaged with the ends of the connecting groove 82. At this time, the two hoppers 5 at the break point are held by the anti-breakage mechanism 8, which prevents the conveyor belt 4 from detaching when it breaks and also prevents the material on the hoppers 5 from falling, thus improving the overall safety.

[0030] The tensioning mechanism 3 includes two mounting plates 31, which are respectively located on both sides of the fixed frame 1. The two ends of the bottom roller shaft are rotatably connected to the two mounting plates 31. Several sliders 11 are provided at the bottom of the fixed frame 1, and the sliders 11 are slidably connected to the mounting plates 31. A fixed plate 32 is connected to the bottom of the fixed frame 1. A screw 33 is connected between the fixed plate 32 and the mounting plate 31. A bolt 34 abuts on both sides of the connection between the screw 33 and the fixed plate 32. A bolt 34 abuts on both sides of the connection between the screw 33 and the mounting plate 31. Adjusting the bolts 34 can fix the distance between the plate 32 and the mounting plate 31, thereby changing the tension on the conveyor belt 4.

[0031] A pressure detector 9 is installed on the bolt 34 that abuts against the fixed plate 32. The pressure detector 9 is located between the fixed plate 32 and the bolt 34. The pressure detector 9 is electrically connected to an alarm 91. When the conveyor belt 4 breaks, the two hoppers 5 at the break point are pulled by the anti-breakage mechanism 8. At this time, the overall length of the conveyor belt 4 increases and the tension decreases rapidly, causing a sudden change in the pressure reading at the pressure detector 9. This indicates that a break has occurred, triggering an alarm to remind the operator to handle the abnormality and ensuring the overall safety of the device.

[0032] Several baffles 41 are evenly arranged on both sides of the conveyor belt 4, with the baffles 41 spaced apart. The baffles 41 extend towards one side of the hopper 5. A protective net 6 is provided around the outside of the fixed frame 1, and the conveyor belt 4 is inside the protective net 6. The risk of material falling is reduced by the baffles 41 and the protective net, ensuring safe use.

[0033] Specifically, the scraper is set as a hopper 5. During transportation, the material is scooped into the hopper 5, reducing the probability of falling. At the same time, several baffles 41 are set on both sides of the conveyor belt 4 to prevent the material from falling between the conveyor belt 4 and the power unit 2, reducing the risk of damage to the conveyor belt 4.

[0034] An anti-breakage mechanism 8 is provided between two adjacent hoppers 5. The connecting rod 83 is simultaneously slidably engaged with the connecting groove 82 of the two adjacent hoppers 5 through the end posts 84 at both ends. When the conveyor belt 4 breaks, the connecting rod 83 can prevent the conveyor belt 4 from falling off by pulling the two hoppers 5 at the break point, thus avoiding the goods falling and improving safety.

[0035] When the conveyor belt 4 breaks, it is pulled together by the connecting rods 83 on both sides. At this time, the overall length of the conveyor belt 4 increases, which reduces the tension on the conveyor belt 4. The value on the pressure detector 9 changes abruptly, causing the alarm 91 to sound, thus reminding the operator to repair it in time to ensure the overall safety of the scraper conveyor.
