Description

Technical Field

[0001] The invention belongs to the technical field of disc feeders, and in particular relates to a disc feeder capable of preventing material blockage and material accumulation. Background Art

[0002] The equipment of the material mixing and transportation system in the metallurgical industry, such as silos, disc feeders, small belt equipment, etc., after the material falls from the silo to the disc feeder, the disc feeder evenly drops the material onto the small belt, and the small belt evenly feeds the material. The current problem is that if the material humidity is high, it is easy to clump into blocks, and the material blocks often get stuck at the outlet of the disc feeder, resulting in the inability to discharge the material normally. Frequent dredging is required, which also affects the uniformity of feeding. The motor of the disc feeder is variable frequency, so the speed of its turntable can be adjusted, and then the speed of material discharge can be adjusted. When the required feeding amount is reached, the small belt feeding is stopped, and the disc feeder and the small belt are interlocked and stopped. However, since the motor of the disc feeder is variable frequency, it takes some time for it to stop. During this period of time, the disc feeder gradually slows down to 0, but it still discharges materials. At this time, the small belt has stopped, and the fallen materials accumulate on the small belt until they fall to the ground, causing material waste. Cleaning up the accumulated materials increases the workload, and the accumulated materials accumulated on the belt also affect the uniformity of the next feeding. Of course, you can calculate the downtime of the disc feeder, stop the disc feeder first, and then delay stopping the small belt, but there are also disadvantages to doing so. For example, if the downstream equipment fails and the feeding needs to be stopped urgently, the small belt needs to be stopped immediately, and material accumulation will still occur at this time; during the period of the disc feeder shutdown, the material discharge is not uniform, which affects the uniformity of the feeding. Summary of the invention

[0003] The object of the present invention is to provide a disc feeder which can prevent material blockage and material accumulation, so as to solve the problems existing in the prior art.

[0004] The technical solution adopted by the present invention to solve the technical problem is:

[0023] In order to make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the following further elaborates on the present invention in detail in combination with specific embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] As Figures 1-5 shown, a disk feeder for preventing material blockage and accumulation is provided with a turntable 1 and a baffle 2. There is an annular gear ring 3 below the turntable 1. A gear transmission mechanism is fixed on the outer wall of the baffle 2. The gear transmission mechanism includes a first bevel gear 23 and a fourth bevel gear 26. A driven shaft 5 and a driving shaft 6 are rotatably connected above the discharge end of the baffle 2. A fifth bevel gear 7 is installed on the driving shaft 6. The first bevel gear 23 meshes with the annular gear ring 3, and the fourth bevel gear 26 meshes with the fifth bevel gear 7. Connecting plates 8 are fixed on both the driven shaft 5 and the driving shaft 6. Pin shafts 9 are inserted into the upper and lower ends of the two connecting plates 8, and at least one hammer piece 10 is sleeved on the pin shafts 9. A U-shaped frame 11 is fixed on the baffle 2, and a cylinder 12 is installed on the U-shaped frame 11. The output end of the cylinder 12 is fixed with a material guiding plate 13. It should be noted that other structures of the disk feeder, such as the base, motor, and bevel gears for driving the turntable 1 to rotate, are all prior arts without any improvement, so they are not shown in the drawings. Only the structures related to the present invention are drawn, which does not prevent those skilled in the art from understanding the present invention.

[0025] On the outer wall of the baffle 2, an upper mounting plate 14 and a lower mounting plate 15 are welded. The upper mounting plate 14 is horizontally arranged. The lower mounting plate 15 has a horizontal mounting surface and a vertical mounting surface. At the top ends of the inner and outer circles of the baffle 2, ear plates 4 are welded. At the discharge end of the baffle 2, a housing 17 is fixed.

[0026] The housing 17 communicates with the discharge end of the baffle 2. The bottom end of the housing 17 is open, and the open end at the bottom of the housing 17 is located outside the baffle 2. When the hammer pieces 10 break the materials and throw them backward, the housing 17 can play a guiding role to prevent the materials from being scattered onto the ground.

[0027] On the ear plates 4, bearing seats 16 are bolted. The driven shaft 5 and the driving shaft 6 are respectively fixed at the rotating ends of the two bearing seats 16. The rotating shafts of the driven shaft 5 and the driving shaft 6 are coaxial. The connection positions of the driven shaft 5 and the driving shaft 6 with the connecting plate 8 are both located at the central positions of the connecting plate 8.

[0028] The gear transmission mechanism further includes a first rotating shaft 21, a second rotating shaft 22, a second bevel gear 24, and a third bevel gear 25. The first rotating shaft 21 is connected by bearings to the vertical mounting surface of the lower mounting plate 15. The second rotating shaft 22 is installed by bearings on the horizontal mounting surfaces of the upper mounting plate 14 and the lower mounting plate 15. The first bevel gear 23 and the second bevel gear 24 are respectively fixed at both ends of the first rotating shaft 21. The third bevel gear 25 and the fourth bevel gear 26 are respectively fixed at both ends of the second rotating shaft 22. The second bevel gear 24 meshes with the third bevel gear 25.

[0029] Both ends of the hammer piece 10 have through holes 18. The hammer piece 10 is sleeved on the pin shaft 9 through any one of the two through holes 18. Both sides of the hammer piece 10 are serrated. Sleeve tubes 19 are sleeved on the pin shafts 9 between the hammer piece 10 and the connecting plate 8 and between the hammer piece 10 and the hammer piece 10. The diameter of the through hole 18 is larger than the diameter of the pin shaft 9. Therefore, the hammer piece 10 can rotate freely on the pin shaft 9. The purpose of the sleeve tube 19 is to prevent the hammer piece 10 from moving horizontally left and right significantly on the pin shaft 9, but it can move horizontally within a small range (such as 2 - 3 mm), and the sleeve tube 19 does not affect the free rotation of the hammer piece 10 on the pin shaft 9.

[0030] Both ends of the U-shaped frame 11 are respectively welded to the inner and outer circles of the baffle 2. On both sides inside the U-shaped frame 11, sliding grooves 20 are provided. Both ends of the guide plate 13 are inserted into the sliding grooves 20.

[0031] The working principle of the present invention is:

[0032] Electrically interlock the cylinder 12, the disk feeder, and the small belt conveyor. During normal use, the material in the storage bin falls onto the disk feeder. First, start the disk feeder, and the cylinder 12 retracts in interlock. The material guide plate 13 does not intercept the material. After the disk feeder discharges the material, start the small belt conveyor (it is also possible to interlock the start of the disk feeder with the start of the small belt conveyor and make the start of the small belt conveyor have a certain time delay). As the turntable 1 rotates, the material is discharged from the discharge end of the disk feeder. The annular gear 3 at the bottom end of the turntable 1 drives the first bevel gear 23 to rotate at the same time. The first bevel gear 23 drives the connecting plate 8 to rotate through the first rotating shaft 21, the second bevel gear 24, the third bevel gear 25, the second rotating shaft 22, the fourth bevel gear 26, the fifth bevel gear 7, and the driving shaft 6 in sequence. The rotation of the connecting plate 8 causes the hammer 10 on the pin shaft 9 to rotate and swing to strike the material. If the material agglomerates into blocks, it will be broken, thereby preventing the material from blocking the discharge end of the disk feeder. When the hammer 10 strikes, it will throw the material backward, and the housing 17 plays a guiding role, so that the thrown-up material falls onto the small belt conveyor from the open end at its bottom.

[0033] When the small belt conveyor stops, the disk feeder stops in interlock, and the cylinder 12 starts to extend in interlock, causing the material guide plate 13 to fall and block the material, thereby preventing the disk feeder from continuously discharging material during the shutdown process and causing the small belt conveyor to accumulate material.

[0034] The above embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various variations and improvements made by those of ordinary skill in the art to the technical solution of the present invention shall fall within the protection scope of the present invention.

[0035] The technologies, shapes, and structures not detailedly described in the present invention are all well-known technologies.
