Description
TECHNICAL FIELD
[0001] The utility model relates to linear vibration screen technical field especially a linear vibration screen. BACKGROUND
[0002] The existing linear vibration screen needs to place the working channel to be inclined to make the work material move on it to the direction of inclination (small vibration amplitude and easy to jam), however in some specific working environment, due to the discharge port of the machine on the feeding side of the vibration screen is lower, and the work material storage container on the discharge side of the vibration screen is higher, so that the working channel of the vibration screen can only be kept parallel to the horizontal plane as far as possible, the height of the discharge port of the working channel is improved as far as possible, and the height of the feeding port of the working channel is reduced as far as possible to adapt to the machine that discharges and feeds cooperatively.
[0003] And the general linear vibration screen is driven by double vibration motors, and the exciting force is generated by the eccentric blocks rotating in the opposite direction synchronously, so that the screen body vibrates along the linear track. The material is thrown up and jumps forward on the screen surface, realizing grading or screening, however, the use of too many motors in the driving mechanism leads to easy failure and high cost. SUMMARY
[0004] In view of the above situation, it is necessary to provide a linear vibration screen solving at least one of the above problems.
[0005] A linear vibration screen, comprising a working channel, a linear driving mechanism, a rebound mechanism and a base;
[0006] The linear driving mechanism is arranged on the base, and the driving end of the linear driving mechanism is connected to the working channel through a connecting part, and the rebound mechanism is connected to the base and the connecting part.
[0007] The linear driving mechanism is used for driving the connecting part to move the working channel on the inclined track at a preset angle, and when the linear driving mechanism drives the connecting part to move, the connecting part drives the rebound mechanism to store energy, so that the rebound mechanism drives the connecting part to move in the opposite direction when resetting, to drive the work material on the working channel to jump to the discharge side.
[0008] By arranging the rebound mechanism, only the linear driving mechanism is needed to realize the function of the linear vibration screen. When the linear driving mechanism drives the connecting part to move, the rebound mechanism is energized, and has a tendency to reset, and drives the connecting part to move in the opposite direction in the process of resetting, so as to realize the effect that the working channel reciprocates in an inclined direction, the overall cost is reduced, and the failure rate is low.

For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood through specific circumstances.
[0018] Please refer to Figures 1-4 The utility model discloses a linear vibrating screen, including work channel 200, linear drive mechanism 400, rebound mechanism 300 and base 100,
[0019] Linear drive mechanism 400 is arranged on base 100, and the driving end of linear drive mechanism 400 is connected with work channel 200 through connecting portion 500, and rebound mechanism 300 is connected with base 100 and connecting portion 500,
[0020] Linear drive mechanism 400 is used to drive connecting portion 500 to move work channel 200 on the oblique trajectory of preset angle, when linear drive mechanism 400 drives connecting portion 500 to move, connecting portion 500 drives rebound mechanism 300 to store energy, and then makes rebound mechanism 300 drive connecting portion 500 to move to the opposite direction when resetting, to drive connecting portion to make the work material on work channel to jump to the discharge side.
[0021] In the embodiment, by setting rebound mechanism 300, only linear drive mechanism 400 can realize the function of linear vibrating screen, when linear drive mechanism 400 drives connecting portion 500 to move, rebound mechanism 300 is stored energy, and has the tendency of resetting, and drives connecting portion 500 to move to the opposite direction in the process of resetting, to drive connecting portion to make the work material on work channel to jump to the discharge side, and reciprocate, to realize the effect that work channel 200 reciprocates in an inclined direction, the overall cost is reduced, and the failure rate is lower.
[0022] Wherein, the oblique trajectory can be inclined downward from the feeding side to the discharge side (same as inclined upward from the discharge side to the feeding side), or inclined downward from the discharge side to the feeding side (same as inclined upward from the feeding side to the discharge side),
[0023] Specifically, in one case, when the oblique trajectory is inclined downward from the discharge side to the feeding side, i.e. the displacement direction of the driving end of linear drive mechanism 400 is inclined downward from the discharge side to the feeding side, at this time, rebound mechanism 300 is a spring or elastic steel plate, and the displacement direction of rebound mechanism between energy storage and resetting is also inclined downward from the discharge side to the feeding side, i.e. the displacement direction of the driving end of linear drive mechanism 400 and the displacement direction of rebound mechanism 300 are same or exist a certain angle, so that linear drive mechanism 400 and rebound mechanism 300 cooperate, to achieve the effect that connecting portion 500 drives work channel 200 to reciprocate in the direction of inclined downward from the discharge side to the feeding side, and then drive connecting portion to make the work material on work channel to jump to the discharge side.
[0024] In this case, linear drive mechanism 400 can be inclined above or below rebound mechanism.
[0025] The downward oblique angle can be in the range of 5-80° with the horizontal plane (the angle range is only applicable to the case that the displacement direction of the driving end of the linear driving mechanism 400 and the displacement direction of the rebound mechanism 300 are the same or have a smaller included angle).
[0026] The angle can be selected according to actual needs. If the angle is smaller, the workpiece will jump higher and the forward distance will be smaller, resulting in low screening efficiency. If the angle is larger, the workpiece will jump lower and the forward distance will be larger.
[0027] The displacement direction of the driving end of the linear driving mechanism 400 and the displacement direction of the rebound mechanism 300 can have a certain included angle according to the downward oblique angle, as long as the corresponding functions can be achieved.
[0028] In another case, the oblique trajectory is downward oblique from the feeding side to the discharging side, i.e., the displacement direction of the driving end of the linear driving mechanism 400 is downward oblique from the feeding side to the discharging side. In this case, the displacement direction of the driving end of the linear driving mechanism 400 and the displacement direction of the rebound mechanism 300 need to have an included angle, which is described in detail in the following embodiments.
[0029] Note: Here, "downward" does not mean that it can only move downward, but refers to the direction.
[0030] In an embodiment, the oblique trajectory is downward oblique from the feeding side to the discharging side.
[0031] When the linear driving mechanism 400 drives the connection part 500 to move, the connection part 500 drives the rebound mechanism 300 to store energy, and the rebound trajectory of the rebound mechanism 300 forms an included angle less than 90° with the oblique trajectory.
[0032] In this embodiment, the linear driving mechanism 400 is arranged on the base 100, the driving end of the linear driving mechanism 400 is connected to the connection part 500, and the driving end of the linear driving mechanism 400 is located obliquely above, and the stroke direction forms an oblique trajectory.
[0033] The connection part 500 is driven by the linear driving mechanism 400 to move on the oblique trajectory, which acts on the rebound mechanism 300 connected to the connection part 500 during the movement, and makes the rebound mechanism 300 store energy, and drives the connection part 500 to move in the opposite direction when the rebound mechanism 300 resets, thereby achieving the purpose of reciprocating oblique vibration of the connection part 500.
[0034] Since the rebound trajectory of the rebound mechanism 300 forms an angle less than 90° with the oblique trajectory, the rebound mechanism 300 can drive the connecting part 500 to move obliquely upward to the discharge side when resetting, and the work material jumps to the discharge side on the work channel 200 at this time;
[0035] As can be understood, since the rebound trajectory of the rebound mechanism 300 is not on the same straight line as the oblique trajectory, an angle is formed between the two, so the moving trajectory of the connecting part 500 and the work channel 200 is not a straight line, but a flat circular trajectory.
[0036] In an embodiment, the work channel 200 is divided into an upper sieve and a lower sieve, the upper sieve is arranged above the lower sieve, and a sieve element is arranged between the upper sieve and the lower sieve.
[0037] In this embodiment, by arranging the upper sieve and the lower sieve, the secondary work material screened by the upper sieve through the sieve element is concentrated through the lower sieve.
[0038] In an embodiment, the lower sieve is arranged obliquely downward from the feeding side to the discharge side, and the upper sieve and the lower sieve are both provided with a guide channel 700 at the discharge side.
[0039] In this embodiment, by arranging the lower sieve to be inclined, the concentration and delivery of the secondary work material are facilitated, and by arranging the guide channel 700 at the discharge side, the position of the secondary work material storage box can be set according to the actual situation.
[0040] In an embodiment, the sieve element is a plurality of transversely arrayed rods 600, and a plurality of the rods 600 are arranged on the same horizontal plane.
[0041] In this embodiment, by arranging the sieve element as a plurality of transversely arrayed rods 600, a secondary work material falling gap is formed between adjacent rods 600, so that even if the secondary work material is initially stuck in the gap during the jumping process, it will fall from a certain gap during the next jump, and will not be mixed with the work material and discharged from the upper sieve discharge port, affecting the screening result of the work material.
[0042] In an embodiment, the rebound mechanism 300 includes at least two groups of elastic steel plates, the elastic steel plates are arranged obliquely downward from the feeding side to the discharge side, and the angle between the elastic steel plates and the horizontal plane is less than the angle between the oblique trajectory and the horizontal plane.
[0043] In this embodiment, the rebound mechanism 300 is arranged as an elastic steel plate, and since the moving trajectory of the connecting part 500 and the work channel 200 is a flat circular trajectory, the service life is longer and more stable compared with a spring.
[0044] The rebound trajectory of the elastic steel plate is perpendicular to the plane in which it is located, and the oblique trajectory is located between the rebound trajectory of the elastic steel plate and the plane in which the elastic steel plate is located.
[0045] Two sets of elastic steel plates are arranged on both sides of the linear driving mechanism.
[0046] In an embodiment, the angle between the elastic steel plate and the horizontal plane is 40-50°.
[0047] In this embodiment, the angle between the elastic steel plate and the horizontal plane is 40-50°, which is the best effect. If the angle is too small, the workpiece will jump and be easily biased high, the forward distance is small, and the screening efficiency is low. If the angle is too large, the workpiece will jump and be easily biased low, the forward distance is large, and it is easy to be stuck in the gap.
[0048] In an embodiment, the angle between the elastic steel plate and the inclined trajectory is 5-20°.
[0049] In this embodiment, the placement direction and driving direction of the linear driving mechanism 400 are limited, so as to cooperate with the placement angle of the elastic steel plate to achieve better rebound force and direction.
[0050] In an embodiment, a connecting seat 900 is arranged below the base 100, and the base 100 is connected to the connecting seat 900 through an elastic member 800.
[0051] In this embodiment, the connecting seat 900 is arranged, and the base 100 is connected to the connecting seat 900 through the elastic member 800, so that the base 100 does not move with vibration during work, but only shakes under the action of the elastic member 800.
[0052] In this embodiment, the elastic member 800 is a spring.
[0053] In an embodiment, the linear driving mechanism 400 is a traction electromagnet or a linear vibrator.
[0054] Preferably, the linear driving mechanism 400 is a traction electromagnet.
[0055] In an embodiment, the working frequency of the traction electromagnet is 12-18hz.
[0056] In this embodiment, the working frequency of the traction electromagnet is 12-18hz, which is determined by the overall workmanship and weight. Generally, 12-18hz can meet the better effect and demand.

Although the present application has been disclosed with preferred embodiments, it is not intended to limit the present application.
