[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Specific examples are given below.

[0032] See also Figures 1 to 6 The utility model provides a scraper chain energy-breaking device, comprising a cover plate 2, four supporting legs 1 are fixedly mounted on the bottom of the cover plate 2, a power switch 5 is fixedly mounted on one side of the cover plate 2, and a feed port 7 is opened at one end of the top of the cover plate;

[0033] The energy-cutoff protection mechanism 3 is provided on one side of the top of the cover plate 2;

[0034] A conveying mechanism 4 is rotatably mounted on one side of the cover plate 2;

[0035] A collecting mechanism 6 is fixedly mounted on opposite sides of two adjacent supporting legs 1;

[0036] The energy-breaking protection mechanism 3 includes a first groove 31, which is opened on one side of the top of the cover plate 2. Fixed blocks 32 are fixedly installed on both sides of the first groove 31, and first threaded rods 312 are threadedly installed on the other two sides of the first groove 31. A fixed shaft 33 is movably installed on the inner surface of the fixed block 32. Two support seats 34 are fixedly installed on one side of the first groove 31, and an L-shaped rotating rod 341 is rotatably installed on the top of the support seat 34. Two sensors 351 are arranged on the top of the cover plate 2.

[0037] In production, we often encounter situations where equipment needs to be repaired. To ensure safety during maintenance, the power needs to be disconnected before maintenance. However, it is also possible that the power is supplied by mistake, resulting in accidents during equipment operation.

[0038] First, turn off the power of the equipment through the power switch 5, and then take the fixed shaft 33 out of the fixed block 32. At this time, the top of the maintenance sleeve 311 loses the restraint of the fixed shaft 33, and the maintenance sleeve 311 can be easily moved away from the first groove 31. Then manually rotate the L-shaped rotating rod 341, put the top of the L-shaped rotating rod 341 into the first groove 31, and rotate the two first threaded rods 312 respectively so that the two first threaded rods 312 fix the top of the L-shaped rotating rod 341. At this time, the L-shaped rotating rod 341 extends into the part below the cover plate 2 to prevent the transmission mechanism 4 from running. The energy-breaking protection mechanism 3 can ensure that when the equipment is being repaired, even if someone accidentally turns on the power, the equipment will not rotate, and will not pose a threat to the safety of the maintenance personnel. The position of the L-shaped rotating rod 341 can be detected by the sensor 351, and the sensor 351 is linearly connected to the power switch 5. When the L-shaped rotating rod 341 is connected to the first threaded rod 312, the equipment will not run even if the power is turned on. Multiple insurances jointly control the start of the equipment, effectively avoiding the accidental start of the equipment and effectively ensuring the safety of the maintenance personnel.

[0039] Further, such as Figures 2 to 4 As shown, the cover plate 2 located at the top of the first groove 31 is fixedly installed with an inspection sleeve 311, and the first threaded rod 312 is threadedly installed on both sides of the inspection sleeve 311. A second groove 321 is opened on the upper part of the fixing block 32, and a second threaded rod 322 is threadedly installed on the top of the fixing block 32. The second threaded rod 322 passes through the top of the fixing block 32 and extends to the inner cavity of the second groove 321. A threaded cap 323 is fixedly installed on the top of the second threaded rod 322. A limit shaft 332 is movably installed in the inner cavity of the second groove 321, and the outer surface of the limit shaft 332 is fixed A fixed shaft 33 is installed, and the limiting shaft 332 is located at an eccentric position of the fixed shaft 33. A handle 331 is fixedly installed on one side of the fixed shaft 33. The two support seats 34 are fixedly installed on the top of the cover plate 2. A third groove 342 is opened on the top of the L-shaped rotating rod 341, and a connecting rod 343 is fixedly installed on the opposite surfaces of the two third grooves 342. Two support blocks 35 are fixedly installed on the top of the support leg 1, and sensors 351 are fixedly installed on the opposite surfaces of the two support blocks 35. The two sensors 351 and the support seats 34 are in the same vertical plane.

[0040] When the equipment is to be repaired, the repair sleeve 311 needs to be separated from the first groove 31. First, the second threaded rod 322 is rotated by the threaded cap 323 to allow the limiting shaft 332 to move in the second groove 321. At this time, the limiting shaft 332 and the fixed shaft 33 can be taken out by moving left and right. The repair sleeve 311 loses the restraint of the fixed shaft 33 and can be easily moved away from the first groove 31 by the handle 331.

[0041] Then, the L-shaped rotating rod 341 is manually rotated so that the top of the L-shaped rotating rod 341 enters the bottom of the cover plate 2, so that the third groove 342 corresponds to the first threaded rod 312, and the first threaded rod 312 is rotated into the third groove 342 to fix the L-shaped rotating rod 341. The connecting rod 343 connects the two L-shaped rotating rods 341 so that the two L-shaped rotating rods 341 can rotate synchronously.

[0042] After the L-shaped rotating rod 341 is fixed, the sensor 351 detects in real time and links the power switch 5. When the L-shaped rotating rod 341 is fixed to the bottom of the cover plate 2, the power switch 5 is turned on in time and the device will not start.

[0043] Further, such as Figure 5 As shown, the conveying mechanism 4 includes a motor 41, which is fixedly installed on one side of the supporting leg 1. The output shaft of the motor 41 is fixedly connected to a gear 42, the gear 42 is meshed with a chain 43, and the chain 43 is fixedly connected to a plurality of scrapers 44.

[0044] The conveying mechanism 4 is powered by a motor 41, and the gear 42 and the chain 43 are meshed to drive the scraper 44 to move, thereby conveying the materials loaded into the device.

[0045] Further, such as Figure 6 As shown, the collecting mechanism 6 includes a first collecting groove 61, which is fixedly installed between two adjacent supporting legs 1. A second collecting groove 62 is fixedly installed on one side of the first collecting groove 61. Two springs 63 are fixedly installed on the bottom of the inner surface of the second collecting groove 62, and a vibration plate 64 is fixedly installed on the top of the two springs 63.

[0046] Since the scraper machine is used in metallurgy and electricity, the material conveyed by the equipment is mostly metal slag. During the conveying process, some metal slag may stick to the scraper 44. After the scraper 44 conveys the material to the first collecting trough 61, some metal slag still remains on the scraper 44. Driven by the chain 43, the scraper 44 carrying the material residue continues to move. When moving to the top of the vibration plate 64, the scraper 44 collides with the vibration plate 64. Since the bottom of the vibration plate 64 is connected to the spring 63, the vibration plate 64 will not affect the continued movement of the scraper 44, but the collision can vibrate the material residue on the scraper 44 into the second collection trough 62. The second collection trough 62 is tilted. During the operation of the equipment, as the material accumulates, the material will slide into the first collection trough 61, which is convenient for the staff to collect and process the material scraped out by the equipment.

[0047] Working principle: First, the material is transported into the scraper through the feed port 7, and the scraper transports the material to the first collecting tank 61, and the vibration plate 64 cleans up the material residues stuck on the scraper 44.

[0048] When the equipment needs to be repaired, first turn off the power through the power switch 5, rotate the second threaded rod 322 to release the limit shaft 332 and the fixed shaft 33 and take out the limit shaft 332 and the fixed shaft 33, take out the maintenance sleeve 311 through the handle 331, rotate the L-shaped rotating rod 341 to the third groove 342 to correspond to the first threaded rod 312, rotate the first threaded rod 312 to the third groove 342, fix the L-shaped rotating rod 341, and the detector 351 detects that the L-shaped rotating rod 341 is fixed, limiting the power output. At this time, even if the power switch 5 is turned on, the equipment will not start.

[0049] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
