Description

Technical Field

[0001] The utility model relates to the field of conveyor belts, in particular to a scraper conveyor. Background Art

[0002] In coal mines and other mines, the excavated ore needs to be transported and collected. In modern mines, scraper conveyors are often used to perform this task.

[0003] However, the existing scraper conveyors have defects: a single driving wheel is driven by a driving device to drive the belt. This driving method may cause the driving wheel to slip due to factors such as water, oil, ice or frost accumulating on the non-working surface of the belt, which reduces the friction and affects the conveying efficiency; at the same time, driving by a single driving wheel will also produce a large kinetic energy loss, thereby reducing the efficiency of transportation.

[0004] In view of this, in order to overcome the above technical problems, the utility model designs a scraper conveyor to solve the above technical problems. Utility Model Content

[0005] The utility model provides the following technical solutions:

[0006] The utility model provides a scraper conveyor, which comprises a base frame, a conveyor belt, a power roller, a linkage component and a power component.

[0007] A plurality of power rollers are rotatably mounted on the base frame, and the power rollers are connected by linkage components. A conveyor belt is sleeved on the power rollers. A power component is also mounted on the base frame, and the power component is used to drive the power rollers to rotate so as to drive the conveyor belt to run. The linkage component is used to drive the plurality of power rollers to rotate together.

[0008] The linkage assembly includes a plurality of crankshafts and linkage rods, one end of the crankshaft is fixedly connected to the rotating shaft of the power roller, the other end of one of the crankshafts is connected to the power assembly, the axis of the crankshaft coincides with the axis of the power roller, and the linkage rod is hinged to the connecting rod journal on the crank of each crankshaft.

[0009] During operation, the power assembly will drive the leftmost power roller to rotate, and the crank shaft on the leftmost power roller will also rotate. The crank shaft drives the linkage rod to move, and the linkage rod drives the remaining crank shafts to rotate, thereby driving the remaining power to rotate, and finally driving the conveyor belt to operate.

[0010] Compared with a single powered roller driving the conveyor belt, the method of using linkage components to drive multiple groups of powered rollers to drive the conveyor belt has the advantages of greater friction between the powered rollers and the conveyor belt, more stability, stronger power, and lower kinetic energy loss.

[0011] Preferably, the power assembly includes: a transmission wheel, a belt, a power wheel and an electric motor, the rotating shaft of the transmission rod is fixedly connected to the crank shaft, the electric motor is fixedly mounted on the base frame, the power wheel is fixedly connected to the rotor of the electric motor, the belt is in contact with the power wheel and the transmission wheel, and the diameter of the transmission wheel is larger than that of the power wheel.

[0012] The motor drives the power wheel to rotate, which in turn drives the belt to run, and the belt drives the transmission wheel and the power roller to rotate. Since the transmission wheel has a larger diameter than the power wheel, the transmission wheel will obtain a smaller rotation speed and a larger torque, which will bring greater power to the conveyor belt.

[0013] Preferably, the conveyor belt is equipped with a plurality of scrapers, one side of which is arc-shaped. The arc-shaped scraper can better drive the mineral raw materials and other materials to move, and the arc-shaped scraper on one side is suitable for mine tunnels with inclined ground.

[0014] Preferably, the power roller is provided with a plurality of anti-skid patterns, the anti-skid patterns are used to increase the friction between the power roller and the conveyor belt, and the anti-skid patterns are provided in the middle section of the power roller. By providing the anti-skid patterns, the kinetic energy of the power roller can be well transferred to the conveyor belt, thereby avoiding unnecessary kinetic energy loss.

[0015] Preferably, baffles are provided on the base frame, and the baffles are located on both sides of the conveyor belt. By providing the baffles, materials on the conveyor belt can be prevented from falling off.

[0016] Preferably, the base frame is provided with a pouring mouth, and the pouring mouth is arranged at the end of the conveyor belt. The pouring mouth can guide the material on the conveyor belt into a designated point.

[0017] Beneficial effect: When in operation, the power assembly drives the leftmost power roller to rotate, and the crankshaft on the leftmost power roller also rotates, and the crankshaft drives the linkage rod to move, and the linkage rod drives the remaining crankshafts to rotate, and then drives the remaining power to rotate, and finally drives the conveyor belt to operate. Compared with a single power roller driving the conveyor belt to operate, the method of using a linkage assembly to drive multiple groups of power rollers to drive the conveyor belt to operate has the advantages of greater friction between the power roller and the conveyor belt, more stability, stronger power, and lower kinetic energy loss.

The present application will be described in detail with reference to the accompanying drawings and in combination with the embodiments. In view of the problems of instability, large kinetic energy loss, insufficient power, etc. of the existing scraper conveyor, the following solution is proposed:

[0027] A scraper 21 conveyor comprises a base frame 1, a conveyor belt 2, a power roller 3, a linkage assembly 4 and a power assembly 5.

[0028] A plurality of power rollers 3 are rotatably mounted on the base frame 1, and the power rollers 3 are connected by a linkage assembly 4. The power rollers 3 are sleeved with a conveyor belt 2. A power assembly 5 is also mounted on the base frame 1. The power assembly 5 is used to drive the power rollers 3 to rotate so as to drive the conveyor belt 2 to run. The linkage assembly 4 is used to drive the plurality of power rollers 3 to rotate together.

[0029] The linkage assembly 4 includes a plurality of crank shafts 41 and linkage rods 42, one end of the crank shaft 41 is fixedly connected to the rotating shaft of the power roller 3, the other end of one of the crank shafts 41 is connected to the power assembly 5, the axis of the crank shaft 41 coincides with the axis of the power roller 3, and the linkage rod 42 is hinged to the connecting rod journal on the crank of each crank shaft 41.

[0030] During specific operation, the power assembly 5 will drive the leftmost power roller 3 to rotate, and the crank shaft 41 on the leftmost power roller 3 will also rotate. The crank shaft 41 drives the connecting rod 42 to move, and the connecting rod 42 drives the remaining crank shafts 41 to rotate, thereby driving the remaining power to rotate, and finally driving the conveyor belt 2 to operate.

[0031] Compared with a single power roller 3 driving the conveyor belt 2, the method of using a linkage assembly 4 to drive multiple groups of power rollers 3 and thus drive the conveyor belt 2 has the advantages of greater friction between the power rollers 3 and the conveyor belt 2, greater stability, stronger power, and lower kinetic energy loss.

[0032] like Figure 4 As shown, the power assembly 5 includes: a transmission wheel 51, a belt 52, a power wheel 53 and a motor 54.

[0033] The motor 54 drives the power wheel 53 to rotate, thereby driving the belt 52 to run, and the belt 52 drives the transmission wheel 51 and the power roller 3 to rotate. Since the diameter of the transmission wheel 51 is larger than that of the power wheel 53, the transmission wheel 51 will obtain a smaller rotation speed and a larger torque, thereby providing greater power to the conveyor belt 2.

[0034] like Figure 4As shown, the power roller 3 is provided with a plurality of anti-skid patterns 31, and the anti-skid patterns 31 are used to increase the friction between the power roller 3 and the conveyor belt 2, and the anti-skid patterns 31 are provided in the middle section of the power roller 3. By providing the anti-skid patterns 31, the kinetic energy of the power roller 3 can be well transferred to the conveyor belt 2, thereby avoiding unnecessary kinetic energy loss.

[0035] like Figure 4 As shown, baffles 11 are provided on the base frame 1, and the baffles 11 are located on both sides of the conveyor belt 2. By providing the baffles 11, materials on the conveyor belt can be prevented from falling off.

[0036] like Figure 4 As shown, a pouring spout 12 is provided on the base frame 1, and the pouring spout 12 is provided at the end of the conveyor belt 2. The inverted buckle can guide the material on the conveyor belt 2 into a designated point.

[0037] Working method: When in operation, the power assembly 5 will drive the leftmost power roller 3 to rotate, and the crank shaft 41 on the leftmost power roller 3 will also rotate. The crank shaft 41 drives the linkage rod 42 to move, and the linkage rod 42 drives the remaining crank shafts 41 to rotate, thereby driving the remaining power to rotate, and finally driving the conveyor belt 2 to operate.
