Technical Field

The utility model relates to a stroke shaft positioning device of a jigger.

Background

The jigger is mechanical equipment commonly used in the material sorting process, and the jigger mainly utilizes the characteristic that materials with different specific gravities have different settling velocities in water or air to layer the materials. Use the ore dressing operation as an example, jigging machine that uses in the current mining field includes the jigging chamber, and the material layering is gone on in the jigging chamber, has water and screen cloth in the jigging chamber, and the indoor water of jigging reciprocates under power unit's effect and drives the mineral and beat from top to bottom, and the mineral aggregate that proportion is big can sink into the bottom, and the mineral aggregate that proportion is little then can shift to the upper strata to realize the layering of material. The jigging machine uses the reciprocating action of a side-acting diaphragm to make the water in the jigging chamber reciprocate up and down, the diaphragm is arranged on the side wall of the jigging chamber, an eccentric driving mechanism serving as a power mechanism is connected with a horizontal stroke shaft and drives the stroke shaft to reciprocate, and the stroke shaft drives the diaphragm to generate regular impact on water.

In the existing jigger, a stroke shaft positioning device for positioning a stroke shaft is arranged, and as shown in fig. 1, the device comprises a supporting frame 07, a positioning seat 05 is arranged on the supporting frame 07, and the stroke shaft 01 is assembled in the positioning seat 05. A sliding bearing, namely an alloy tile 04, is arranged between the positioning seat 05 and the stroke shaft 01, and in order to ensure the lubricating effect, an oil injection channel 06 extending along the radial direction is arranged on the positioning seat 05 and the alloy tile 04, so that the lubricating oil can enter between the stroke shaft 01 and the alloy tile 04 from the outside. Adaptively, sealing rings 03 are arranged at two ends of the alloy tile 04, and a gland 02 for compressing the sealing rings in the positioning seat is arranged on the positioning seat, so that the lubricating oil is prevented from leaking from the positioning device.

When the jigger works, the stroke shaft is driven by the eccentric driving mechanism to reciprocate in the alloy tile, so that the diaphragm is driven to deform in the horizontal direction to impact water flow, and the support and lubrication of the stroke shaft in the positioning device are concentrated at the alloy tile. However, the structure has the following defects in practical operation:

1) because the positioning seat is fixed, and sliding friction exists between the stroke shaft and the alloy tile of the positioning seat, in order to reduce the influence of friction on the action of the stroke shaft, lubricating oil is filled between the stroke shaft and the alloy tile, and meanwhile, a sealing ring for preventing the lubricating oil from leaking is arranged at the end part of the alloy tile; in addition, lubricating oil is easy to lose efficacy after being accidentally leaked, so that a burning dead point is formed between the stroke shaft and the alloy tile, and the sealing ring is further damaged;

2) the stroke shaft which does high-speed reciprocating motion is easy to abrade the alloy tile, the motion direction of the stroke shaft can be deviated, and then the diaphragm driven by the stroke shaft is deformed along the direction deviated from the original axis, so that the diaphragm is easy to damage.

In the two kinds of circumstances above, the diaphragm that no matter what kind of reason leads to damages, all can reduce the life of jigging machine, must shut down the maintenance after the diaphragm damages simultaneously and overhaul the maintenance, can influence normal production, and the reliability is poor.

The features and performance of the stroke shaft positioning device of the jig of the present invention will be described in further detail with reference to the following embodiments.

In order to make the description of embodiment 1 of the stroke shaft positioning device more clear, the description is mainly combined with the state of the stroke shaft positioning device when the stroke shaft positioning device is used on a jigger, that is, the description is carried out by taking the jigger as a main object: the jigging machine is mainly used in mineral separation operation and can screen out ores with different specific gravities in a layered mode. As shown in fig. 2, 3 and 4, the jigger mainly comprises a frame 10 and a box body 20 fixedly connected to the frame 10, the inner cavity of the box body 20 is a place mainly used for mineral separation, a partition plate is arranged in the inner cavity to divide the whole inner cavity into two regions, each region corresponds to a jigging chamber of the jigger, namely, in fig. 2, the partition plate in a straight shape extends along the left-right direction to form two jigging chambers adjacent to each other along the front-back direction, and when the jigger works, the box body 20, namely, each jigging chamber is filled with water.

Two diaphragms 30 are arranged on two opposite side plates of the box body 20, at the moment, four diaphragms 30 are arranged on the side plates in total, two diaphragms 30 on the same side plate form a group, at the moment, the two groups of diaphragms 30 are opposite in the front-back direction, one group of diaphragms 30 on the side plates correspond to the adjacent jigging chambers, and one jigging chamber is provided with two diaphragms 30 on the same side. The diaphragm 30 is made of rubber materials, can elastically deform under the action of external force, and when the diaphragm 30 deforms, the corresponding volume of the jigging chamber changes, so that the water in the jigging chamber can make up-and-down reciprocating jumping.

Two stroke shafts 41 extending in the horizontal direction are arranged in the jigger, the two stroke shafts 41 are arranged on two side plates provided with the diaphragms 30 in a parallel mode in a penetrating mode, the parts of the stroke shafts 41 extending out of the two side plates are respectively fixedly connected with the two opposite diaphragms 30, and when the stroke shafts 41 reciprocate, the two opposite diaphragms 30 can be driven to elastically deform towards the same direction synchronously, so that the volume of the corresponding jigging chamber is changed.

A power mechanism for driving a stroke shaft 41 to move is fixed on a frame 10 of the jigger, the power mechanism comprises a motor 40 serving as a power source, the motor 40 is in transmission connection with a speed reducer 42 through belt transmission, and the speed reducer 42 is connected with the stroke shaft 41 through an eccentric driving mechanism 43, so that the stroke shaft 41 can reciprocate in the horizontal direction. The reducer 42 used in this embodiment is a dual-output shaft reducer, and can establish a transmission connection relationship with the two-stroke shaft 41 at the same time, so as to realize a one-to-two layout structure. The eccentric drive mechanism 43 used in this embodiment is a crank commonly used in existing jiggers and is not expanded in detail here.

Because the diaphragm 30 is driven by the reciprocating stroke shaft 41 to deform so as to make the water in the jigging chamber bounce up and down in a reciprocating manner, the motion state of the stroke shaft 41 is very important for the whole jigging machine, and in order to ensure that the stroke shaft 41 can stably and accurately reciprocate along a set path, a stroke shaft positioning device 50 matched with the stroke shaft 41 is also arranged in the jigging machine. The stroking shaft positioning means 50 are used in pairs, the stroking shaft positioning means of each pair engaging with the same portion of the stroking shaft extending from the side plate.

When the through hole of the clamping plate 521 is aligned with the hinge hole of the shaft sleeve 512, the hinge shaft 517 is inserted, and the swing arm 52 is hinged with the fixing piece 51. In this hinge structure, articulated shaft 517 who uses is the step shaft, and its middle part is the major diameter section, and both ends are the minor diameter section, and when articulated assembly, gland nut is equipped with soon to the tip that passes two splint respectively of articulated shaft 517 both ends minor diameter section, can compress tightly the clamp plate on the articulated shaft after gland nut and articulated shaft 517 tighten.

Meanwhile, in order to reduce the friction force between the rolling bearing 515 and the hinge shaft 517, lubricating oil is filled between the integral sleeve and the stroke shaft 41, and in order to prevent the lubricating oil from being exposed from the sleeve 512, sealing rings 516 serving as sealing structures are arranged at both ends of the hinge hole in the sleeve 512, and when the two clamping plates 521 clamp both ends of the fixing member 51, the sealing of the end portion of the integral sleeve is realized by cooperating with the sealing rings 516.

The sliding bearing 534 matched with the adapting hinge shaft 535 is also arranged in the adapting hinge seat 53, the sliding bearing 534 is an integral shaft sleeve, when the fixing piece 51 reciprocates along with the stroke shaft 41, the swing arm 52 swings relative to the adapting hinge seat 53, so lubricating oil is also arranged between the integral shaft sleeve and the adapting hinge shaft 535, specifically, an oil filling channel for the flowing of the lubricating oil is arranged on the adapting hinge shaft 535, the inlet of the oil filling channel is positioned at the end position of the adapting hinge shaft, and the outlet of the oil filling channel is positioned on the outer peripheral surface of the adapting hinge shaft. Seal rings 536 are also provided as sealing structures in the adapter hinge mount at both ends of the integral bushing to prevent leakage of lubricant from the adapter hinge mount 53.

As shown in fig. 5, 6 and 7, when the device is used in the jigger described above, there are two pairs of the stroke shaft positioning devices 50, each pair of the stroke shaft positioning devices 50 corresponds to both ends of the same stroke shaft 41, four oil injection pumps 60 are provided on the outer side wall of the casing in one-to-one correspondence with the stroke shaft positioning devices, a plurality of oil injection pipes 61 are connected to the oil injection pumps, and the other ends of the oil injection pipes 61 communicate with inlets of oil injection passages provided on the hinge shaft and the fitting hinge shaft. The oil injection pump 60 is a hand-operated oil pump, and can inject oil to the hinged position of the stroke shaft positioning device at any time according to requirements.

In the jigger described above, the screen 23 is provided in the casing, the upper screen discharge opening 21 for discharging the material located above the screen 23 in height is provided at one end of the screen 23 in the casing, and the ore discharge opening 22 for supplying water and discharging some special materials is provided at the bottom of the casing. When the ores are screened, water is injected firstly, water is injected into the jigging chamber continuously, the water is discharged from the oversize discharge port 21 and the ore discharge port 22 continuously, and the water level is kept stable in the jigging chamber by controlling the flow of inlet water and outlet water. Under the action of the jumping water force, the materials are layered on the screen, the materials with larger specific gravity form a heavy material bed layer on the screen, and the materials with lighter specific gravity are positioned on the heavy material bed layer, so the oversize discharge port 21 is correspondingly divided into a light material outlet 212 and a heavy material outlet 211, so that the ore materials with different specific gravity and different heights are taken away from the jigging chamber through the corresponding outlets by the water flow.

Specifically, light material outlets 212 are respectively arranged on two sides of the heavy material outlet 211, the height of the heavy material outlet 211 is lower than that of the light material outlet 212, and an isolation structure is arranged between the heavy material outlet 211 and the light material outlet 212, so that light materials and heavy materials at different heights enter different channels and are discharged through the corresponding heavy material outlet 211 and the light material outlet 212. Apart from the difference in height between the heavy material outlet 211 and the light material outlet 212, a V-shaped guide plate is further disposed at the heavy material outlet 211, and the V-shaped guide plate is movably disposed in the vertical direction, so that the opening size of the heavy material outlet 211 can be adjusted by adjusting the height of the V-shaped guide plate in the vertical direction.

When throwing materials, heavy materials need to form a bed layer in the jigging chamber after a certain time, so generally when the jigging machine just starts to work, the V-shaped guide plate is downwards adjusted, the bottom of the V-shaped guide plate is in contact with the screen, and then the heavy materials cannot be directly discharged from the heavy material outlet 211, after accumulation for a certain time, a heavy material bed layer is formed in the jigging chamber, and then the V-shaped guide plate is lifted up, so that the heavy materials can also be discharged out of the jigging chamber along with water flow through the heavy material outlet 211.

In the working process of the jigger, the stroke shaft 31 can drive the diaphragm 30 to deform while acting, and the deformation of the diaphragm correspondingly causes the water flow in the jigging chamber to generate pulses in different directions, so that the water flow impacts materials to be screened. The ore with lighter specific gravity can float, and the heavy material ore with heavier specific gravity can sink to the below of light material ore, discharges the jigging room through the export that corresponds afterwards under the drive of rivers.

In the layered screening process, the stroke shaft 41 is driven by the motor to reciprocate at a high speed, the stroke of the reciprocating motion is about 5cm, and meanwhile, the stroke shaft 41 is supported by the stroke shaft positioning device 50 and jumps in the up-down direction during the reciprocating motion. The length of the swing arm 52 in the stroke shaft positioning device 50 is about 50cm, and the length of the swing arm 52 is much longer than the stroke of the reciprocating motion, so that the distance of the stroke shaft 41 moving in the up-and-down direction is very small, and meanwhile, the diaphragm 30 can also elastically deform when acting along with the stroke shaft, and the self deformation amount is used for compensating the rising or falling of the stroke shaft 41.

When the stroke axle is doing reciprocating motion, among the stroke axle positioner, the position that articulated shaft and slide bearing mainly contacted is the bottom of articulated shaft outer peripheral face, the bottom of slide bearing inner peripheral face, and the position that adaptation articulated shaft and slide bearing mainly contacted is the bottom of adaptation articulated shaft outer peripheral face and the bottom of slide bearing inner peripheral face, uses slide bearing to rotate the support articulated shaft in this embodiment, and the support effect is good, and stability is also higher.
