Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of scraper conveyors, in particular to a movable scraper conveyor. BACKGROUND

[0002] The movable scraper conveyor is a continuous conveying equipment for conveying bulk materials, which mainly consists of scraper chain, sprocket, trough, driving device and tensioning device, etc. The scraper is installed on the chain, and through the driving of the sprocket, the scraper moves in the trough to push the materials along the conveying direction. For example, the movable scraper conveyor disclosed in patent No. CN104670804A.

[0003] The existing movable scraper conveyor needs to push the materials by the scraper during use. After long-term pushing of the materials, the scraper will be deformed due to factors such as excessive impact force, extrusion of the materials or friction with the trough wall. After the deformation of the scraper, the gap between the scraper and the bottom and side wall of the trough will change. Under normal circumstances, the scraper can effectively push the materials forward, but the deformed scraper may not be tightly matched with the trough. For example, the middle part of the scraper is deformed upward, and when pushing the materials, the materials are easy to leak from the two sides and the bottom of the scraper and cannot be effectively scraped and conveyed, thereby reducing the conveying efficiency. Since there are many scrapers inside the scraper conveyor, it is difficult for the operator to find and replace the deformed scraper in time, which affects the convenience of the operator to replace the scraper.

[0042] The operating principle of the present invention is explained as follows: When the movable scraper conveyor is needed, an electrical signal is sent to the PLC controller 10 through the control switch of the external device. After receiving the electrical signal, the PLC controller 10 will control the drive motor 6 to work. The drive motor 6 will drive the drive shaft 4 to rotate. The drive shaft 4 will drive the two drive teeth 5 on the surface to rotate. The drive teeth 5 will drive the two chains 9 and the two driven teeth 8 to rotate together. The chains 9 will drive the scraper assembly 11 to move. The scraper assembly 11 will push the material falling into the conveyor and transport the material to the target point through the discharge port 3.

[0043] When the scraper frame 111 is deformed due to extrusion, collision or friction of the material, the space inside the scraper frame 111 will be extruded, so that the gas inside the scraper frame 111 is transported into the connecting frame 112 through the air inlet, so that the air pressure close to the piston plate 15 below is increased, and the piston plate 15 will drive the placing seat 16 and the conductive block 17 to move away from the scraper frame 111 under the push of the air pressure, and the conductive block 17 will contact the conductive plate 18 in the process of moving upward, the conductive block 17 is electrically connected with the external power supply, and the conductive plate 18 is electrically connected with the PLC controller 10, when the conductive block 17 contacts the conductive plate 18, an electric signal will be sent to the PLC controller 10, and the PLC controller 10 will control the external prompting mechanism to work (the external prompting mechanism is a buzzer, which reminds the surrounding operators with a dripping sound), and the PLC controller 10 will also control the indicator lamp 19 corresponding to the conductive plate 18 to work (the surface of the indicator lamp 19 is provided with a protective cover, which can protect the indicator lamp 19), so that the operator can quickly find the deformed scraper frame 111 and replace it later;

[0044] And the scraper frame 111 pushes the material on the surface of the bottom plate 2 at the same time, the friction block 22 contacts the upper surface of the bottom plate 2, the friction between the friction block 22 and the upper surface of the bottom plate 2 can make the friction block 22, the vertical rod 21 and the moving block 202 overcome the elastic force of the spring to move, when the upper surface of the bottom plate 2 is worn due to the scraping of the material, the roughness of the upper surface of the bottom plate 2 will increase, so that the friction between the friction block 22 and the bottom plate 2 increases, the increased friction will make the moving block 202 continue to move and extrude the detection switch 23, and the detection switch 23 will send an electric signal to the PLC controller 10, and the PLC controller 10 will control the external prompting mechanism to work (the external prompting mechanism is a buzzer, which reminds the surrounding operators with a dripping sound), so that the operator can replace the worn bottom plate 2, avoid the wear of the bottom plate 2 continue to increase, and the material will leak back from the gap between the scraper frame 111 and the bottom plate 2, thereby affecting the conveying efficiency;

[0045] Reference Figure 2When the chain 9 drives the scraper frame 111 to move upwards, the upper scraper frame 111 will be squeezed to the first arc-shaped block 35 during the movement, so that the first arc-shaped block 35 moves upwards, and the first arc-shaped block 35 will be squeezed upwards to the frequency counter 342, so that the movement speed of the scraper frame 111 can be detected by the frequency counter 342. When the driving teeth 5 and the driven teeth 8 are worn, or the driving teeth 5 are embedded with impurities in the tooth groove (the driving teeth 5 are arranged near the discharge port 3, and when the scraper frame 111 pushes the material to move, some impurities in the material will be thrown to the driving teeth 5 under the action of a large pushing force, and the impurities will be stuck in the tooth groove of the driving teeth 5 under the squeezing of the driving teeth 5 and the chain 9), causing the chain 9 to skip teeth, the movement speed of the chain 9 driving the scraper frame 111 will decrease. When the PLC controller 10 detects this situation through the frequency counter 342, the small electric push rod 36 will work reciprocatingly once, the small electric push rod 36 drives the installation ring 37 and the air inlet assembly 43 to move downwards together, and the air inlet assembly 43 is kept for two seconds at the bottom, so that one scraper frame 111 is squeezed to the second arc-shaped block 44, the second arc-shaped block 44 drives the top plate 45 to move upwards through the round rod 432, the top plate 45 is squeezed to the telescopic air bag 47, the gas in the telescopic air bag 47 is transported to the horizontal box 38 through the hose 39, the air pressure of the space on the left side of the piston block 40 is increased, and the piston block 40 moves to the right under the action of the air pressure by a certain distance. Then the PLC controller 10 controls the small electric push rod 36 to drive the air inlet assembly 43 to move upwards, at the same time, the PLC controller 10 also controls the lateral electric push rod 282 on both sides to work, so that the lateral electric push rod 282 drives the cleaning frame 29 to move towards the driving teeth 5, so that the metal bristles 33 on the surface of the cleaning belt 32 contact the driving teeth 5. Then the PLC controller 10 controls the cleaning motor 31 to work, the cleaning motor 31 drives the rotating shaft 30 to rotate, the rotating shaft 30 drives the outer cleaning belt 32 to rotate, and the cleaning belt 32 drives the metal bristles 33 to rotate, so as to clean the impurities adhered to the surface of the driving teeth 5. When the cleaning work is performed for one minute, the PLC controller 10 controls the lateral electric push rod 282 to drive the cleaning frame 29, the cleaning belt 32 and the metal bristles 33 to return to the initial position. When one minute is over, the PLC controller 10 continues to detect the movement speed of the scraper frame 111 through the frequency counter 342. When the chain 9 skips teeth again, the above steps are repeated. When the third detection shows that the chain 9 skips teeth, the piston block 40 will squeeze the trigger switch 41, the trigger switch 41 will send an electric signal to the PLC controller 10, and the PLC controller 10 will control the external prompting mechanism to work (the external prompting mechanism is a buzzer, which reminds the surrounding operators with a “dong dong dong” tone) to remind the operators to detect the wear degree of the driven teeth 8 and the driving teeth 5.

[0046] When the chain 9 is loose due to long-term use and wear, the driven shaft 7 will move a certain distance to the left under the action of the spring force inside the moving box 242, so that the pressure sensor between the adjusting rod 26 and the supporting plate 25 detects that the extrusion force becomes smaller. When the PLC controller 10 detects that the extrusion force becomes smaller through the pressure sensor, the PLC controller 10 will work through the hydraulic cylinder 241, and the hydraulic cylinder 241 will push the moving box 242 to move to the left, so that the moving box 242 applies pressure to the supporting plate 25 through the internal spring, so that the supporting plate 25 applies pressure to the driven shaft 7 and the chain 9, so that the chain 9 is kept at a set degree of tightness, thereby ensuring the conveying efficiency of the conveyor.

[0047] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
