Description

Technical Field

[0001] The invention relates to the technical field of ore conveying equipment, in particular to a swing-type ore feeder for continuous magnetite ore. Background Art

[0002] In the ore mining and processing industry, feeders are key conveying equipment, and their performance directly affects the efficiency and stability of the entire production process. Traditional feeders gradually expose many limitations when facing special materials such as magnetite.

[0003] Most of the early feeding equipment had a simple structure and a single function. For example, the common simple hopper feeder only relies on the ore's own gravity to discharge the material. The discharge volume depends entirely on the height of the ore accumulation in the silo and the size of the funnel opening, which is difficult to accurately control. In the early stages of magnetite mining, when the ore output was large and the discharge accuracy requirements were not high, it might barely meet the basic transportation needs. However, with the increasing sophistication of ore processing technology, the accuracy requirements for ore feeding in different production links have become increasingly stringent. This simple feeder cannot flexibly adjust the discharge according to actual working conditions, resulting in either excess ore supply causing waste or insufficient ore supply affecting the continuous operation of subsequent processes, greatly restricting the improvement of production efficiency.

[0004] Moreover, the physical properties of magnetite ore also pose severe challenges to traditional feeders. Magnetite ore is hard and prone to uneven particle sizes during mining and transportation. When large-sized ore enters the feeder bin, the conventional feeder outlet lacks an adaptive adjustment mechanism and is prone to blockage. Once a blockage occurs, it will not only take a lot of manpower and time to clear it, but also force the entire production line to be interrupted, causing maintenance costs to soar, seriously disrupting the production rhythm and causing huge economic losses to the company. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a continuous swing feeder for magnetite ore, which solves the problem that the discharge amount of the traditional swing feeder is fixed and easy to be blocked.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a continuous swing feeder for magnetite ore, comprising a silo, wherein the top opening of the silo is a feed inlet, the bottom opening is a feed outlet, and vertical adjustment plates and tilt adjustment plates are respectively embedded and slidably connected in two opposite side walls of the end face of the feed outlet, and a swing bucket is also provided on the silo body, and the swing bucket is driven to swing back and forth by an eccentric mechanism, the swing axis of the swing bucket is close to the feed inlet of the silo, the bottom wall of the swing bucket is located below the feed outlet of the silo, and an adjustment mechanism is provided above the feed outlet of the silo, and the adjustment mechanism is used to drive the swing bucket, the vertical adjustment plate and the tilt adjustment plate to move in a reciprocating manner. The adjustment plate and the inclined adjustment plate rise and fall synchronously. When the adjustment mechanism drives the swing bucket, the vertical adjustment plate and the inclined adjustment plate to descend synchronously, the diameter of the silo discharge port gradually decreases. When the adjustment mechanism drives the swing bucket, the vertical adjustment plate and the inclined adjustment plate to rise synchronously, the diameter of the silo discharge port gradually increases. An auxiliary adjustment device is also provided at the bottom end of the vertical adjustment plate for independently adjusting the state of the vertical adjustment plate. The eccentric mechanism is connected to the silo through a synchronization device. When the swing bucket descends, the synchronization device drives the eccentric mechanism to move toward the silo. When the swing bucket rises, the synchronization device drives the eccentric mechanism to move away from the silo.

[0007] Preferably, two chute grooves are symmetrically provided on two side walls of the silo parallel to the swing direction of the swing bucket, a slider is slidably connected in the chute, and both ends of the swing shaft respectively pass through and are rotatably connected to the middle of the two sliders.

[0008] Preferably, the adjusting mechanism includes a cylinder, the outer wall of the cylinder is fixedly connected to the silo, the output end of the cylinder is fixedly connected to a cross bar, one end of the cross bar is continuously connected to the middle part of the swing shaft through a pull rod, and the other end is fixedly connected to one end of a main rope, the other end of the main rope passes through a pulley and is divided into four branch cables, the four branch cables respectively pass through the outer wall of the silo, and are respectively fixedly connected to the top walls of the vertical adjustment plate and the inclined adjustment plate, and the pulley base is fixedly connected to the outer wall of the silo.

[0009] Preferably, a spring 1 is arranged between the top wall of the vertical adjustment plate and the silo, and the spring 1 is used to provide a downward pushing force to the vertical adjustment plate. A spring 2 is arranged between the top wall of the inclined adjustment plate and the silo, and the spring 2 is used to provide an inclined downward pushing force to the inclined adjustment plate.

[0011] Preferably, the synchronization device includes a slide rail bracket, the sliding end of the slide rail bracket is fixedly connected to the bottom wall of the reducer, the mounting end surface of the slide rail bracket is fixedly connected to the outer wall of the silo, the two sides of the reducer are respectively rotatably connected to one end of two symmetrically arranged connecting rods, the other end of the connecting rod is rotatably connected to one end of a lever, the other end of the lever is rotatably connected to the outer wall of the swing shaft, and the middle part of the lever is rotatably connected to the outer wall of the silo.

[0012] Preferably, the auxiliary adjustment device includes a rotating shaft, both ends of the rotating shaft are respectively rotatably connected to the lower wall of the vertical adjustment plate, the outer wall of the rotating shaft is fixedly connected to a baffle, a torsion spring is arranged between the baffle and the vertical adjustment plate, and the side wall on one side of the baffle is fit with the outer wall of the vertical adjustment plate facing the silo through the torsion spring, the side wall on the other side of the baffle is connected to the winder through a cable, and the base of the winder is fixedly connected to the outer wall on the other side of the vertical adjustment plate.

[0013] The present invention provides a continuous swing feeder for magnetite ore, which has the following beneficial effects: The present invention sets an adjusting mechanism and cooperates with a synchronizing device, so that when the adjusting mechanism drives the swing bucket, the vertical adjusting plate and the inclined adjusting plate to synchronously descend, the diameter of the silo discharge port gradually decreases, and the synchronizing device drives the eccentric mechanism to move toward the silo; when the adjusting mechanism drives the swing bucket, the vertical adjusting plate and the inclined adjusting plate to synchronously rise, the diameter of the silo discharge port gradually increases, and the synchronizing device drives the eccentric mechanism to move away from the silo, thereby achieving the purpose of adjusting the diameter of the silo discharge port. On the one hand, the discharge amount of the swing feeder can be adjusted, thereby improving the applicability of the swing feeder. On the other hand, when large-particle-size ore is blocked, the diameter of the discharge port is temporarily increased so that the blocked large-particle-size ore can be discharged smoothly, thereby avoiding the problem of blockage. At the same time, through the setting of the auxiliary adjustment device, the state of the vertical adjustment plate is adjusted independently. On the one hand, when more precise adjustment of the discharge amount is required, the winder drives the cable to pull the baffle to rotate, so that the baffle rotates to the bottom of the shaft, thereby extending the vertical adjustment plate, and then realizing fine adjustment of the height of the lowest point of the vertical adjustment plate, which plays an auxiliary fine adjustment role in the discharge amount. On the other hand, when blockage occurs, the winder drives the cable to pull the baffle to rotate, and the baffle provides an upward force to the vertical adjustment plate under the resistance of the ore. At this time, the vertical adjustment plate overcomes gravity and the elastic force of spring one and rises, thereby temporarily expanding the discharge port, and at the same time exerts an outward turning force on the blocked ore, so that the blocked ore can be quickly discharged.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Please see attached Figure 1 -Attached Figure 5 The embodiment of the present invention provides a continuous swing feeder for magnetite ore, including a silo 1, the top opening of the silo 1 is a feed inlet, the bottom opening is a discharge outlet, and a vertical adjustment plate 2 and an inclined adjustment plate 3 are respectively embedded and slidably connected in two opposite side walls of the end face of the discharge outlet, and a swing bucket 4 is also provided on the silo body of the silo 1, and the swing bucket 4 is driven to swing back and forth by an eccentric mechanism, and a swing shaft 401 of the swing bucket 4 is close to the feed inlet of the silo 1, and the bottom wall of the swing bucket 4 is located below the discharge outlet of the silo 1, and an adjustment mechanism is provided above the discharge outlet of the silo 1, and the adjustment mechanism is used to drive the swing bucket 4, the vertical adjustment plate 2 and the inclined adjustment plate 3 to swing back and forth. The silo 1 is lifted and lowered step by step. When the adjusting mechanism drives the swing bucket 4, the vertical adjusting plate 2 and the inclined adjusting plate 3 to descend synchronously, the diameter of the discharge port of the silo 1 is gradually reduced. When the adjusting mechanism drives the swing bucket 4, the vertical adjusting plate 2 and the inclined adjusting plate 3 to rise synchronously, the diameter of the discharge port of the silo 1 is gradually increased. An auxiliary adjusting device is also provided at the bottom of the vertical adjusting plate 2 for independently adjusting the state of the vertical adjusting plate 2. The eccentric mechanism is connected to the silo 1 through a synchronizing device. When the swing bucket 4 descends, the synchronizing device drives the eccentric mechanism to move toward the silo 1. When the swing bucket 4 rises, the synchronizing device drives the eccentric mechanism to move away from the silo 1.

[0018] Silo 1 is used as the temporary storage and transportation starting part of the ore. Its top opening is used as the feed port, which is convenient for pouring a large amount of ore. The bottom opening is the discharge port, which is the channel for the ore to flow to the subsequent process. The end face of the discharge port is cleverly inlaid and slidably connected with a vertical adjustment plate 2 and an inclined adjustment plate 3 in the two side walls opposite to each other. These two adjustment plates are like precision valves that can flexibly adjust the size of the discharge port. The swing bucket 4 equipped on the silo 1 body is driven to swing back and forth by an eccentric mechanism. Its swing shaft 401 is close to the feed port of silo 1, and the bottom wall is just below the discharge port of silo 1. Such a layout allows the ore to fall into the swing bucket 4 from the discharge port in an orderly manner, and continuous feeding is achieved as the swing bucket 4 swings.

[0019] By setting the adjusting mechanism and cooperating with the synchronizing device, when the adjusting mechanism drives the swing bucket, the vertical adjusting plate 2 and the inclined adjusting plate 3 to descend synchronously, the diameter of the discharge port of the silo 1 gradually decreases, and the synchronizing device drives the eccentric mechanism to move toward the silo 1. When the adjusting mechanism drives the swing bucket 4, the vertical adjusting plate 2 and the inclined adjusting plate 3 to rise synchronously, the diameter of the discharge port of the silo 1 gradually increases, and the synchronizing device drives the eccentric mechanism to move away from the silo 1, thereby achieving the purpose of adjusting the diameter of the discharge port of the silo 1. On the one hand, the discharge amount of the swing feeder can be adjusted, thereby improving the applicability of the swing feeder. On the other hand, when large-particle-sized ore is blocked, the diameter of the discharge port is temporarily increased so that the blocked large-particle-sized ore can be discharged smoothly, thereby avoiding the problem of blockage, effectively avoiding the stagnation of the production line caused by blockage, and ensuring the continuity of production.

[0020] Two chute 101 are symmetrically provided on the two side walls of the silo 1 parallel to the swing direction of the swing bucket 4. Slide blocks 102 are slidably connected in the chute 101. Both ends of the swing shaft 401 penetrate and are rotatably connected to the middle of the two slide blocks 102. The adjustment mechanism includes a cylinder 5. The outer wall of the cylinder 5 is fixedly connected to the silo 1. The output end of the cylinder 5 is fixedly connected to a cross bar 6. One end of the cross bar 6 is continuously connected to the middle of the swing shaft 401 through a pull rod 7. The other end of the cross bar 6 is fixedly connected to one end of a main rope 8. The other end of the main rope 8 passes through a pulley 9 and is divided into four branch ropes 10. The four branch ropes 10 pass through the outer wall of the silo 1 respectively and are fixedly connected to the top walls of the vertical adjustment plate 2 and the tilt adjustment plate 3 respectively. The base of the pulley 9 is fixedly connected to the outer wall of the silo 1. A spring 11 is arranged between the top wall of the vertical adjustment plate 2 and the silo 1, and the spring 11 is used to provide a downward pushing force for the vertical adjustment plate 2. A spring 2 12 is arranged between the top wall of the inclined adjustment plate 3 and the silo 1, and the spring 2 12 is used to provide a downward pushing force for the inclined adjustment plate 3. The spring 11 and the spring 2 12 play a role of auxiliary balance and resetting during the adjustment process.

[0021] The operation process of the adjustment mechanism is that the cylinder 5 rises and drives the cross bar 6 to rise, and then the swing bucket 4 is pulled up through the pull rod 7, and at the same time, the vertical adjustment plate 2 and the inclined adjustment plate 3 are pulled up synchronously through the main rope cable 8 and the branch rope cable 10, thereby achieving the purpose of expanding the discharge port; the cylinder 5 rises and drives the cross bar 6 to descend, and then the swing bucket 4 is driven to descend through the pull rod 7, and at the same time, a part of the tension on the main rope cable 8 is released, so that the branch rope cable 10 is relaxed, and under the joint action of gravity, spring 11 and spring 2 12, the vertical adjustment plate 2 and the inclined adjustment plate 3 are synchronously descended, thereby achieving the purpose of reducing the discharge port.

[0022] The eccentric mechanism includes a reducer 13, the input end of the reducer 13 is fixedly connected to the output end of the motor 14, the outer wall of the motor 14 is fixedly installed on the outer wall of the reducer 13, the output end of the reducer 13 is fixedly connected to an eccentric wheel 15, which is rotatably connected to one end of a connecting rod 16 near the outer edge of the eccentric wheel 15, and the other end of the connecting rod 16 is rotatably connected to the lower wall of the swing bucket 4.

[0023] The motor 14 drives the reducer 13 to operate, driving the eccentric wheel 15 to rotate, and then one end of the connecting rod 16 moves eccentrically around the eccentric wheel 15, thereby realizing a push-pull effect on the swing bucket 4, and realizing the periodic swing of the swing bucket 4.

[0024] The synchronization device includes a slide rail bracket 17, the sliding end of the slide rail bracket 17 is fixedly connected to the bottom wall of the reducer 13, the mounting end surface of the slide rail bracket 17 is fixedly connected to the outer wall of the silo 1, the two sides of the reducer 13 are rotatably connected to one end of two symmetrically arranged connecting rods 18, the other end of the connecting rod 18 is rotatably connected to one end of a lever 19, the other end of the lever 19 is rotatably connected to the outer wall of the swing shaft 401, and the middle part of the lever 19 is rotatably connected to the outer wall of the silo 1.

[0025] When the adjusting mechanism drives the swing bucket 4 to rise, the lever 19 drives the connecting rod 18 to press down, pushing the reducer 13 away from the silo 1. When the adjusting mechanism drives the swing bucket 4 to descend, the lever 19 drives the connecting rod 18 to pull up, pulling the reducer 13 close to the silo 1, thereby ensuring that the relative position of the swing bucket 4 and the eccentric mechanism remains unchanged.

[0026] The auxiliary adjustment device includes a rotating shaft 20, both ends of which are rotatably connected to the lower wall of the vertical adjustment plate 2, and a baffle 21 is fixedly connected to the outer wall of the rotating shaft 20. A torsion spring 22 is arranged between the baffle 21 and the vertical adjustment plate 2. The torsion spring 22 makes the side wall of one side of the baffle 21 fit with the outer wall of the vertical adjustment plate 2 facing the silo 1, and the side wall of the other side of the baffle 21 is connected to the winder 24 through a cable 23, and the base of the winder 24 is fixedly connected to the outer wall of the other side of the vertical adjustment plate 2.

[0027] By setting the auxiliary adjustment device, the state of the vertical adjustment plate 2 is adjusted independently. On the one hand, when more precise adjustment of the discharge amount is required, the winder 24 drives the cable 23 to pull the baffle 21 to rotate, so that the baffle 21 rotates to the bottom of the shaft, thereby realizing the extension of the vertical adjustment plate 2, and then realizing the fine adjustment of the height of the lowest point of the vertical adjustment plate 2, which plays a role in assisting the fine adjustment of the discharge amount. On the other hand, when blockage occurs, the winder 24 drives the cable 23 to pull the baffle 21 to rotate, and the baffle 21 provides an upward force to the vertical adjustment plate 2 under the resistance of the ore. At this time, the vertical adjustment plate 2 overcomes the gravity and the elastic force of the spring 11 to rise, thereby temporarily expanding the discharge port, and at the same time exerts an outward turning force on the blocked ore, so that the blocked ore can be quickly discharged.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
