Description

Technical Field

[0001] This utility model relates to the field of trough feeder technology, specifically to a feeding device for a trough feeder. Background Technology

[0002] In various metal mines such as iron ore, copper ore, and gold ore, trough feeders can transport mined blocky ore from the ore bin to subsequent processing equipment such as crushers, and are an important feeding equipment in the mining production process;

[0003] In existing technologies, trough feeders generally consist of a trough body, a drive unit, and a trough bottom plate. Ore material enters the trough body through the feed inlet at the top and rests on the trough bottom plate. The trough bottom plate reciprocates linearly via the drive unit. As the trough bottom plate reciprocates, the ore is evenly transported from inside the trough body to the receiving position. This reciprocating feeding is performed in this way. Since the trough bottom plate moves horizontally, during the movement, the ore material on the trough bottom plate is pushed to the receiving position by the squeezing of the inner wall of the trough body. However, excessive amounts of ore with high moisture content and stickiness may enter the trough body through the feed inlet and accumulate on the trough bottom plate, which may cause blockage in the trough body and affect the feeding effect of the device. Utility Model Content

[0004] This utility model proposes a feeding device for a trough-type ore feeder, which solves the problem of material blockage in the trough, affecting the feeding effect of the device in the prior art.

[0005] The technical solution of this utility model is as follows: A feeding device for a trough-type ore feeder includes a ore feeder body, the ore feeder body including a trough, a trough bottom plate and a support, the trough bottom plate being slidably fitted with the trough, the trough including an inclined plate and two vertical plates, one end of each of the two vertical plates being fixedly connected to the inclined plate, a driving mechanism being provided on the support, and also including two L-shaped frames, a slider, a vibration motor, a push plate and a support assembly, one end of the L-shaped frame being fixedly connected to the support, and the other end being fixedly connected to the outer wall of the trough, the L-shaped frame and the trough forming a sliding cavity, the slider being slidably fitted with the inner wall of the sliding cavity, one end of the slider being fixedly connected to the top of the trough bottom plate, the vibration motor being installed at the bottom end of the trough bottom plate, the push plate being provided on the lower side of the trough bottom plate through an elastic connector, one end of the push plate being rotatably connected to one end of the driving mechanism through a hinge seat, for driving the trough bottom plate to move horizontally, and the support assembly being provided on the outer wall of the L-shaped frame for supporting the push plate.

[0006] Preferably, in order to cause the bottom plate of the trough to move up and down repeatedly when it vibrates under the drive of the vibration motor, the elastic connector includes multiple connecting springs and a telescopic rod. The two ends of the multiple connecting springs are respectively fixedly connected to the bottom end of the bottom plate and the top end of the push plate. The connecting springs are sleeved on the outer side wall of the telescopic rod, and the two ends of the telescopic rod are respectively fixedly connected to the bottom end of the bottom plate and the top end of the push plate.

[0007] Furthermore, in order to support the push plate and assist the push plate in horizontal movement, the support assembly includes two sets of connecting plates, a connecting seat, a connecting shaft, and a support roller. One end of each of the two sets of connecting plates is fixedly connected to the outer side wall of the two L-shaped frames, and each set of connecting plates includes two connecting plates. The top end of the connecting seat is fixedly connected to the bottom end of the connecting plate, and one end of the connecting shaft is fixedly connected to one end of the connecting seat. The support roller is fitted on the connecting shaft and is coaxially rotatably connected to the connecting shaft.

[0008] Furthermore, to prevent gaps from forming between the bottom plate and the tank body during vibration, which could cause ore material to transfer from the gaps to the outside of the tank, a through groove is provided on the bottom plate. A rubber sealing gasket is installed inside the through groove. The rubber sealing gasket has strong elasticity and tensile strength, and has multi-directional tensile capability. The two ends of the rubber sealing gasket are fixedly connected to the inner bottom wall of the through groove and the bottom end of the vertical plate, respectively.

[0009] As a further aspect of this application, to prevent fine ore from entering the channel during vibration of the bottom plate, the outer wall of the rubber sealing gasket is fitted with the inner wall of the channel, and the thickness of the rubber sealing gasket is the same as the width of the vertical plate.

[0010] As a further improvement in this application, in order to support the push plate, the top ends of the plurality of support rollers are all in contact with the bottom end of the push plate.

[0011] The working principle and beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, through the cooperation of the bottom plate, vibrating motor, push plate, support assembly, elastic connector and drive mechanism, the bottom plate is driven to reciprocate horizontal linear motion by the drive mechanism. The bottom plate drives the slider to move in the sliding cavity, and at the same time drives the rubber sealing gasket to stretch laterally. The vibrating motor is started to drive the bottom plate to vibrate. The bottom plate vibrates up and down repeatedly. The vibration motor drives the bottom plate to vibrate. The bottom plate vibrates up and down repeatedly and produces a small longitudinal displacement. Through the vibration of the bottom plate and the horizontal movement of the bottom plate, combined with the pushing of the inclined plate, the sticky ore accumulated in the tank can be transferred out of the tank, avoiding the accumulation of ore material in the tank on the bottom plate and improving the feeding efficiency.

[0013] 2. In this utility model, through the cooperation of the bottom plate, rubber sealing gasket, L-shaped frame and slider, when the bottom plate vibrates and produces a slight longitudinal displacement, the bottom plate drives the rubber sealing gasket to stretch, creating a gap between the bottom plate and the tank body. The rubber sealing gasket "fills" this gap, preventing small minerals in the tank body from transferring from the gap to the outside of the tank body. The slider always moves longitudinally within the sliding cavity, which plays a limiting role on the bottom plate.

[0014] Therefore, the feeding device for this trough feeder is used to solve the problem of material blockage in the trough, which affects the feeding effect of the device in the prior art. Attached Figure Description

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] like Figures 1 to 8 As shown, this embodiment proposes a feeding device for a trough-type ore feeder, including a feeder body 7. The feeder body 7 includes a trough 8, a trough bottom plate 9, and a support 10. The trough bottom plate 9 is slidably fitted with the trough 8. The trough 8 includes an inclined plate 11 and two vertical plates 12. One end of each of the two vertical plates 12 is fixedly connected to the inclined plate 11. A drive mechanism 23 is provided on the support 10. The support also includes two L-shaped frames 13, a slider 14, a vibration motor 15, a push plate 16, and a support assembly. One end of the L-shaped frame 13 is fixedly connected to the support 10, and the other end is fixedly connected to... The outer wall of the trough 8 is fixedly connected, and the L-shaped frame 13 forms a sliding cavity 17 with the trough 8. The slider 14 slides with the inner wall of the sliding cavity 17. The length of the slider 14 is less than the length of the sliding cavity 17. One end of the slider 14 is fixedly connected to the top of the trough bottom plate 9. The vibration motor 15 is installed at the bottom of the trough bottom plate 9. To prevent gaps from forming between the trough bottom plate 9 and the trough 8 during vibration, which would cause the ore material to transfer from the gaps to the outside of the trough 8, a through groove 18 is provided on the trough bottom plate 9. A rubber sealing gasket 19 is installed in the through groove 18. The rubber sealing gasket 19 has strong elasticity and tensile strength, and possesses multi-directional tensile capability. Both ends of the rubber sealing gasket 19 are fixedly connected to the inner bottom wall of the channel 18 and the bottom end of the vertical plate 12, respectively. To prevent small ore particles from entering the channel 18 during vibration of the bottom plate 9, the outer wall of the rubber sealing gasket 19 is fitted against the inner wall of the channel 18. The thickness of the rubber sealing gasket 19 is the same as the width of the vertical plate 12. The vibration motor 15 is activated to drive the bottom plate 9 to vibrate, causing it to repeatedly vibrate up and down. When the bottom plate 9 moves downwards... When in motion, the bottom plate 9 drives the rubber sealing gasket 19 to stretch, creating a gap between the bottom plate 9 and the tank body 8. The rubber sealing gasket 19 "fills" this gap, preventing small ore particles in the tank body 8 from transferring to the outside of the tank body 8. The bottom plate 9 also drives the slider 14 to move downward along the inner wall of the sliding cavity 17. It should be noted that the longitudinal displacement amplitude generated by the vibration motor 15 driving the bottom plate 9 to vibrate up and down is less than the height of the sliding cavity 17. Through the vibration of the bottom plate 9, the ore material in the tank body 8 is prevented from accumulating on the bottom plate 9.

[0027] It should be added that the support 10 includes a main frame 20 and two auxiliary frames 21. Both auxiliary frames are fixedly connected to one end of the main frame 20. One end of the main frame 20 is fixedly connected to one end of the tank 8. The drive mechanism 23 is set on the main frame 20 and located on one side of the tank 8. The drive mechanism 23 includes a motor, a reducer, an eccentric wheel, a transmission belt and a connecting rod. One end of the connecting rod is hinged to the hinge seat 22, and the other end of the connecting rod is fixedly connected to the eccentric wheel. The motor drives the reducer, and the reducer drives the eccentric wheel to rotate. The eccentric wheel drives one end of the connecting rod to rotate, and the other end of the connecting rod drives the reciprocating linear motion of the tank bottom plate 9.

[0028] The push plate 16 is set on the lower side of the bottom plate 9 through an elastic connector. One end of the push plate 16 is rotatably connected to one end of the drive mechanism 23 through the hinge seat 22, which is used to drive the bottom plate 9 to move horizontally. In order to make the bottom plate 9 move up and down repeatedly when it vibrates under the drive of the vibration motor 15, the elastic connector includes multiple connecting springs 1 and telescopic rods 2. The two ends of the multiple connecting springs 1 are fixedly connected to the bottom end of the bottom plate 9 and the top end of the push plate 16, respectively. The connecting springs 1 are sleeved on the outer side wall of the telescopic rods 2. The two ends of the telescopic rods 2 are fixedly connected to the bottom end of the bottom plate 9 and the top end of the push plate 16, respectively. The vibration motor 15 drives the bottom plate 9 to vibrate, and the bottom plate 9 vibrates up and down repeatedly. The bottom plate 9 drives one end of the telescopic rods 2 to stretch and contract repeatedly, and drives one end of the connecting springs 1 to stretch and contract repeatedly. The telescopic rods 2 play a guiding role for the connecting springs 1, so as to prevent the connecting springs 1 from causing the bottom plate 9 to "shake".

[0029] A support assembly is mounted on the outer wall of the L-shaped frame 13 to support the push plate 16. To support the push plate 16 and assist its horizontal movement, the support assembly includes two sets of connecting plates 3, connecting seats 4, connecting shafts 5, and support rollers 6. One end of each set of connecting plates 3 is fixedly connected to the outer wall of one of the two L-shaped frames 13. Each set of connecting plates 3 includes two connecting plates 3. The top end of the connecting seat 4 is fixedly connected to the bottom end of the connecting plate 3. One end of the connecting shaft 5 is fixedly connected to one end of the connecting seat 4. The support roller 6 is fitted onto the connecting shaft 5 and is coaxially rotatably connected to it. The top ends of the push plate 16 and the multiple support rollers 6 are all in contact with the bottom end of the push plate 16. The bottom end of the push plate 16 is supported by the four support rollers 6. When the vibration motor 15 drives the bottom plate 9 to vibrate, and the bottom plate 9 vibrates up and down repeatedly, the push plate 16 maintains longitudinal stability, so that the connecting spring 1 can be compressed to generate elasticity and apply elastic force to the bottom plate 9. When the drive mechanism 23 drives the push plate 16 to move horizontally, the push plate 16 drives the multiple support rollers 6 to rotate, which can assist the movement of the push plate 16. The connecting shaft 5, the connecting seat 4 and the connecting plate 3 support the support rollers 6.

[0030] Working principle: The feeder body 7 is placed in a suitable position, and the ore material is moved into the trough 8. The ore is placed on the bottom plate 9 of the trough. The drive mechanism 23 drives the push plate 16 to perform reciprocating horizontal linear motion. The push plate 16 drives multiple connecting springs 1 and multiple telescopic rods 2 to move. The telescopic rods 2 drive the bottom plate 9 of the trough and the vibration motor 15 to move. During the movement, the bottom plate 9 drives the slider 14 to move in the sliding cavity 17, and at the same time drives the rubber sealing gasket 19 to stretch laterally. At the same time, the vibration motor 15 is started to drive the bottom plate 9 to vibrate. The bottom plate 9 vibrates up and down repeatedly. The vibration motor 15 drives the bottom plate 9 to vibrate, and the bottom of the trough... Plate 9 vibrates up and down repeatedly, producing small longitudinal displacements. When the bottom plate 9 moves downward, it stretches the rubber sealing gasket 19, creating a gap between the bottom plate 9 and the tank body 8. The rubber sealing gasket 19 fills this gap, preventing small ore particles from being transferred from the tank body 8 to the outside. After pressing against the connecting spring 1, the bottom plate 9 moves upward again under the thrust of the connecting spring 1. This repeated vibration allows the sticky ore accumulated in the tank body 8 to be transferred out of the tank body 8, preventing the ore material in the tank body 8 from accumulating on the bottom plate 9 and improving feeding efficiency.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
