Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibrating screen net with a clogging prevention function, which is stretched over an industrial vibrating screen device, and a vibrating screen device using the net.

Conventionally, in this type of vibrating screen, a vibrating screen is stretched between the frames on both sides of the vibrating screen as shown in Patent Document 1, and the object to be sieved is below the vibrating screen. A plurality of axes orthogonal to the flow direction are provided and a partition net is provided, a plurality of storage chambers are formed between the plurality of shafts and the partition net, and a plurality of spheres are stored inside the storage chamber, When the frame vibrates, the plurality of spheres in the storage chamber hit the vibrating screen mesh from below, thereby preventing the vibrating screen mesh from being clogged.

JP, 8-155396, A Japanese Patent Application No. 2017-197345

By the way, the entire vibrating screen is installed such that the vibrating screen itself is slightly inclined downward from the upstream side to the downstream side in the flow direction of the object to be sieved. Then, due to this inclination, the spheres are unevenly distributed on the lower side (downstream side), and the tapping position becomes uneven in each storage chamber or on the surface of the vibrating screen. There is a problem that the effect of preventing clogging cannot be obtained.

Therefore, the inventor of the present invention, as shown in Patent Document 2, provides a vibrating screen net integrally with a vibrating screen net underneath the vibrating screen net, and a vibrating screen for vibrating the vibrating screen. By virtue of this, the beating net hits the lower surface of the vibrating screen net to develop a vibrating screen net that prevents clogging of the vibrating screen net.

This beating net is excellent in the function of preventing clogging of the vibrating screen, but since the vibrating screen is beaten from below, if used for a long time, the metal core wire below the vibrating screen will be used. A horizontal line made of synthetic resin (for example, a circular line having a diameter of 1.6 mm) in which (for example, a diameter of 0.35 mm) is embedded is tapped from the lower side for a long period of time, so that the resin-coated portion covers the core wire. It was found that the metal core wire was moved upward, and as a result, the metal core wire was exposed to the lower side of the covering portion. When the core wire is exposed from the covering portion as described above, it is necessary to replace the vibrating screen mesh, which poses a problem that the life of the vibrating screen is short.

Further, in the vibrating screen mesh with a clogging prevention function of Patent Document 2, thin strip fixing plates are fixed to the lower side of the vibrating mesh at predetermined intervals, and between the thin strip fixing plates, the thin strip fixing plates are The beating net is fixed to the lower side, and in order to fix the vibrating screen to the vibrating screen device, the horizontal lines made of synthetic resin on both sides are fixed between the vibrating upright plates and stretched in opposite directions. (The position of the fixed part is fixed), the anti-vibration rubber and the support rod (support member) are brought into contact with the lower side of each of the thin strip-shaped fixed plates, and the central part of the vibrating screen is moved upward by this support member. By lifting the above, the above-mentioned vibrating screen was set in the vibrating screen device in a state orthogonal to the flow direction of the object to be sieved so as to form an arc shape upward, and also stretched upward. ..

By the way, in the portion of the vibrating screen mesh against which the anti-vibration rubber comes into contact, the thin strip-shaped fixing plate and the beating net are adhered, and the thickness in the vertical direction of that part becomes large, and the part having a large thickness is lowered. The anti-vibration rubber comes into contact from the side. In this case, since the positions of the fixed portions at both ends of the vibrating screen are constant, as a result, the above-mentioned arc of the vibrating screen is largely projected upward, and the object to be sieved is the end parts of the vibrating screen. There was a problem of uneven distribution (see the chain double-dashed line of the vibrating screen in FIG. 6). From the viewpoint of conveying the object to be sieved, the arc of the vibrating screen is preferably as gentle as possible.

The present invention has been made in view of the above-mentioned conventional problems, and by devising the cross-sectional shape of the synthetic resin horizontal wire of the vibrating screen, it is possible to eliminate the exposure of the core wire and prolong the life of the vibrating screen. It is an object of the present invention to provide a net for vibrating screen with a clogging prevention function and a vibrating screen device capable of reducing the convex arc on the screen for vibrating screen.

In order to achieve the above object, the present invention provides
Firstly, a plurality of parallel synthetic resin vertical lines having no core wire, and a plurality of parallel synthetic resin vertical lines intersecting these synthetic resin vertical lines and having metal core wires embedded therein. The horizontal line and the vibrating screen mesh that is heat-welded and integrated at their intersections are stretched on the vibrating screen device with both side edges parallel to the synthetic resin vertical line, and A support member is abutted from below the vibrating screen so that it is stretched in a convex arc shape and vibrated by the vibrating screen device to perform the screen operation of the object to be sieved. Preventing clogging. In the vibrating screen with a function, a plurality of thin strip-shaped fixing plates having a constant width are fixed at a predetermined interval in parallel with the synthetic resin vertical line on the lower side of the vibrating screen, and for the vibrating screen. Below the net and the thin strip-shaped fixed plate, a beating net made of synthetic resin having meshes larger than the squares of the vibrating screen is arranged, and the beating net is located below the thin strip-shaped fixed plate. Is fixed to the thin strip-shaped fixing plate, and is not connected to the lower side of the vibrating screen in the range between the adjacent thin strip-shaped fixing plates. By removing the beating net in the central portion, a fitting concave portion for fitting the head portion of the supporting member is formed in the lower central portion, and the head portion of the supporting member is fitted in the fitting concave portion. In a combined state, the head is configured to be able to contact the lower surface of the thin strip fixing plate, and the vibrating screen is vibrated when the vibrating screen is stretched on the vibrating screen device, so that the beating net is vibrated. By vibrating up and down, the synthetic resin horizontal wire is beaten by the tapping net, and the cross-sectional shape of the synthetic resin horizontal wire is configured such that the lower side from the upper side of the core wire is thicker. It is composed of a vibrating screen net with a clogging prevention function.

The support member can be composed of, for example, a vibration proof rubber (10) and a support rod (11). The material to be sieved is a raw material such as an aggregate. According to this structure, the vibrating screen with clogging prevention function is stretched on the vibrating screen device by fixing both ends of the horizontal line made of synthetic resin to a pair of vibrating upright plates, for example, and the thin strip fixing When the vibration upright plate or the like is vibrated vertically or obliquely in the up-and-down direction including the elliptical locus or the like while the fitting concave portion on the lower side of the plate is supported by a supporting member such as a vibration-proof rubber, each thin strip-shaped fixed plate Since the beating net in between vibrates in the up-down direction with its central portion as the maximum stroke due to elasticity and hits the lower side of the vibrating screen, clogging of the vibrating screen can be prevented. Further, since the beating net is integrally formed with the vibrating screen, the vibrating screen with clogging prevention function can be installed without any trouble even if it is installed in an inclined state. Further, since the beating net on the lower side of the thin strip fixing plate is removed, the fitting recess is formed in the corresponding portion, and the head of the supporting member is fitted in the fitting recess, so that the supporting member is abutted. Since the vertical thickness of the vibrating screen at the contact position can be made thin, a convex arc on the vibrating screen when the vibrating screen with a clogging prevention function is stretched over the vibrating screen device. Can be configured more gently than the conventional device, and uneven distribution of the sieve target to the left and right can be prevented as much as possible. Further, since the synthetic resin horizontal wire on the lower side of the vibrating screen is configured to have a larger wall thickness below the core wire, the life of the vibrating screen can be maintained longer.

Secondly, one edge of the beating net is fixed to the corresponding lower edge of the thin strip fixing plate, and the other edge is adjacent to the thin strip fixing plate. The vibrating screen with a clogging preventing function according to the first aspect is fixed to the corresponding lower edge of the other thin plate-like fixing plate.

According to this structure, the beating net does not exist in the lower central portion of the thin strip-shaped fixing plate, and the fitting recess in which the beating net is removed is formed. The vertical height of the sieve screen can be made thinner than that of the conventional vibrating screen. With this, when a supporting member (for example, a vibration-proof rubber or the like) is fitted into the fitting concave portion, when a vibrating screen net with a clogging prevention function is stretched over the vibrating screen device, an upward convex arc is conventionally formed. Compared with the above, the configuration can be made more gradual, so that uneven distribution of the members to be sieved to the left and right can be suppressed as much as possible.

Thirdly, the cross-sectional shape of the synthetic resin horizontal wire is such that the upper side of the core wire is a semicircular shape and the lower side of the core wire is a rectangular shape having one side in the vertical direction longer than the radius of the semicircular shape. It is constituted by the vibrating screen mesh with the clogging prevention function described in the first or second aspect.

According to this structure, even if the above-mentioned synthetic resin horizontal wire is struck from below by the beating net, the core wire can be effectively prevented from being exposed from the covering portion of the synthetic resin horizontal wire, resulting in vibration. The life of the sieving net can be extended.

Fourthly, a vibrating screen device using the vibrating screen mesh with a clogging prevention function according to the first aspect, wherein both ends of the vibrating screen net with a clogging prevention function are parallel to the vertical line made of synthetic resin. Each of the heads of the plurality of support members fixed to the horizontal rods for fixation fixed between the vibrating upright plates by tensioning the vibrating upright plates in a direction opposite to the lateral direction. By being fitted in the fitting concave portion on the lower side of the vibrating screen mesh, the vibrating screen mesh is stretched upward with tension applied so that the vibrating screen mesh has an upward convex arc shape. Drive means for vibrating the vibrating upright plate is provided, and by driving the drive means, the vibrating upright plate is vibrated to vibrate the beating net up and down. Thus, the vibrating screen device using the vibrating screen net with a clogging prevention function capable of tapping the lower side of the vibrating screen net is used.

The drive means can be composed of a motor (M). According to this structure, when the vibrating upright plate is vibrated in the vertical direction including the elliptical locus or the like or in the oblique vertical direction, the beating net between the thin plate strip-shaped fixed plates vibrates in the vertical direction with its central portion as the maximum stroke, Since the lower side of the vibrating screen is beaten, the clogging of the vibrating screen can be effectively prevented.

According to the present invention, a mesh for vibrating screen with a clogging prevention function is stretched on a vibrating screen device by fixing both ends of a horizontal line made of synthetic resin to a pair of fixing members such as a vibrating upright plate. When the vibration mesh with the upper clogging prevention function is vibrated while the lower side corresponding to the plate is supported by the supporting member, the beating net between the thin strip-shaped fixed plates makes the center part the maximum stroke and moves up and down. Since it vibrates to hit the bottom of the vibrating screen, the clogging of the vibrating screen can be effectively prevented.

Further, since the vibrating screen net and the tapping net are integrated, even if the vibrating screen net with a clogging prevention function is installed at an inclination in the vibrating screen device, spheres are not unevenly distributed as in the conventional case, The function of preventing clogging does not deteriorate.

In addition, since the fitting recess is formed on the lower side of the thin strip fixing plate, and the head of the supporting member fits into the fitting recess, the vertical thickness of the vibrating screen mesh at the contact position of the supporting member. When the vibrating screen with clogging prevention function is stretched over the vibrating screen device, the convex arc on the vibrating screen can be configured more gently than the conventional device. It is possible to prevent uneven distribution of the sieved body to the left and right as much as possible.

In addition, since the synthetic resin horizontal wire on the lower side of the vibrating screen is configured to have a larger wall thickness below the core wire, the life of the vibrating screen can be maintained longer.

When the vibrating upright plate is vibrated in the vertical direction including the elliptical locus, etc. or diagonally in the vertical direction, the beating net between the thin strip-shaped fixed plates vibrates in the vertical direction with the central part as the maximum stroke, and is used for the vibrating screen. Since the bottom side of the net is beaten, it is possible to realize a vibrating screen device which can effectively prevent clogging of the vibrating screen net.

Hereinafter, the mesh for vibrating screen with clogging prevention function and the vibrating screen device according to the present invention will be described in detail.
FIG. 1(a) is a plan view of a vibrating screen mesh 1 with a clogging prevention function, and FIG. 1(b) is a side view of FIG. 1(a). The bar 11 is indicated by a chain double-dashed line. In the figure, the vertical direction (arrow A direction) is called the "vertical direction", and the direction orthogonal to the vertical direction is called the "horizontal direction". When installed in the vibrating screen device, the vertical direction (arrow A direction) is covered. The sieve body shall move.

A vibrating screen mesh 1 with a clogging prevention function according to the present invention comprises a vibrating screen mesh 2 having a small square shape on the upper side, a beating net 4 having a large square shape on the lower side, and a beating mesh 4 for the mesh. It is composed of a thin strip fixing plate 5 for connecting to the back side of the vibrating screen 2. Therefore, in the following description, when the whole mesh is shown, it is referred to as "vibrating screen net 1 with clogging prevention function", and when only the upper vibrating screen net 2 is shown, it is called "vibrating screen net 2". When only the tapping net 4 on the lower side is shown, it is referred to as "tapping net 4".

Here, a horizontal line of the vibrating screen 2 is referred to as a "synthetic resin horizontal line 2a", and a metallic core wire 3 is embedded in the synthetic resin horizontal line 2a (see FIGS. 3 and 5). ). The vertical line of the vibrating screen 2 is referred to as "synthetic resin vertical line 2b", and the synthetic resin vertical line 2b has no core wire embedded therein. Further, the horizontal line of the beating net 4 is referred to as a "synthetic resin horizontal line 4a", and the vertical line of the beating net 4 is referred to as a "synthetic resin vertical line 4b". The synthetic resin horizontal wire 4a and the synthetic resin vertical wire 4b are not embedded with metal core wires.

The synthetic resin horizontal lines 2a and 4a and the synthetic resin vertical lines 2b and 4b are both made of urethane, and the thin strip fixing plate 5 is also made of urethane.

Further, in FIG. 1, the area of the beating net 4 below is larger than the area of the upper vibrating net 2 as shown in an exploded view in order to make the structure easy to understand. As for the vibrating screen net 1 with a function of preventing clogging of the sheets, the vibrating screen net 2 and the beating net 4 have the same area, and a vertical line is provided between the vibrating screen net 2 and the beating net 4. A plurality of the thin strip-shaped fixed plates 5 (lateral width t1) are arranged in parallel to the direction at a constant interval t2 in the lateral direction (see FIG. 4). The vertical length of the thin strip fixing plate 5 is the same as the vertical length of the screen 1 for vibrating screen with clogging prevention function.

As shown in FIG. 1, the vibrating screen 2 crosses a plurality of parallel synthetic resin vertical lines 2b having no core wire on the upper side and below the synthetic resin vertical lines 2b. It is composed of a net in which a plurality of lower parallel synthetic resin horizontal wires 2a in which a metal core wire 3 is embedded are heat-welded at their intersections 2'and are integrated in the vertical and horizontal directions. Therefore, the net directly beaten by the beating net 4 from above is the synthetic resin horizontal wire 2a.

On the lower side of the vibrating screen 2 (below the synthetic resin horizontal line 2a), a thin strip fixing plate 5 having a constant width t1 is arranged at a predetermined interval (in the embodiment, the interval t2) in parallel with the synthetic resin vertical line 2b. , See FIG. 4). More specifically, the thin strip fixing plate 5 is a flexible plate made of urethane having a thickness of about 2 mm to 3 mm, and its upper surface 5a side is fixed to the synthetic resin horizontal wire 2a of the vibrating screen 2 by heat welding. Has been done. The thin strip fixing plates 5 are fixed in parallel to the synthetic resin vertical lines 2b, and a plurality of thin strip fixing plates 5 are provided in parallel to each other with the interval t2 in the lateral direction of the vibrating screen 2. (See FIG. 4). Therefore, in FIG. 1, only two thin strip fixing plates 5 are shown, but actually, as shown in FIG. 6, a plurality of thin strip fixing plates 5 are provided at intervals t2 along the horizontal direction of the vibrating screen 2. It is provided. In the embodiment of FIG. 6, the thin strip fixing plates 5 are provided at three positions of the support column 11 of the vibration-proof rubber 10.

The anti-vibration rubber 10 is formed such that the anti-vibration rubber 10 itself is formed into a vertically long substantially rectangular parallelepiped shape (or a vertically long plate shape) along the thin strip fixing plate 5, and the support rod 11 is provided on the lower surface side of the anti-vibration rubber 10. A plurality of them are provided in the vertical direction at regular intervals, and the lower surface of the thin strip fixing plate 5 is supported along the thin strip fixing plate 5. Instead of providing a plurality of the support rods 11, a plate-shaped support plate 11 that is long in the vertical direction may be provided. The anti-vibration rubber 10 and the support rod 11 or the support plate 11 are referred to as "support member".

The length of the vibration-proof rubber 10 may be the same as that of the thin plate-shaped fixing plate 5, but a plurality of vibration-proof rubbers 10 having a predetermined length shorter than that of the thin plate-shaped fixing plate 5 may be used. The lower side of 5 may be configured to be supported in the vertical direction at regular intervals.

In addition, the support rod 11 or the support plate 11 of the anti-vibration rubber 10 is fixed between the pair of left and right vibrating upright plates 6 and 6'of the vibrating screen device 7 described later with both ends 8'and 8'. It is fixed on the horizontal rail 8 (see FIG. 6). A plurality of the fixing horizontal rods 8 are provided in the vertical direction in a state of being orthogonal to the vertical direction (the flow direction of the object to be sieved) in the pair of the vibration upright plates 6 and 6', and the lower end of the support rod 11 is provided. Alternatively, the lower end of the support plate 11 is fixed. Therefore, the fixing support rod 8, the anti-vibration rubber 10 and the support rod 11 or the support plate 11 vibrate together with the vibration upright plates 6 and 6'.

The upper surface 10a of the anti-vibration rubber 10 as the supporting member is in contact with (abuts against) the back surface 5b of each of the thin plate-shaped fixing plates 5 (see FIG. 1). As a result, when the vibrating screen 2 is stretched on the vibrating screen device, tension is also applied to the upper side so that the vibrating screen 2 has an upward convex arc shape (see FIG. 6 ).

Below the vibrating screen 2 and the thin strip fixing plate 5, there is provided a beating net 4 for eliminating clogging of the mesh larger than the mesh of the vibrating screen 2.

The beating net 4 includes a synthetic resin horizontal line 4a parallel to the synthetic resin horizontal line 2a of the vibrating screen net 2 and a synthetic resin vertical line 2b parallel to the synthetic resin vertical line 2b of the vibrating screen net 2. 4b, and each crossing portion 4'of the synthetic resin horizontal wire 4a and the synthetic resin vertical wire 4b is fixed by heat welding, whereby a tapping net 4 is formed. The diameters of the wires 4a and 4b of the beating net 4 are larger than the diameters of the vertical and horizontal lines 2a and 2b of the vibrating screen 2, and the diameter is about 2 to 2.5 times the diameter of the vibrating screen. It has Further, one mesh of the beating net 4 is configured to have about 16 times the size of one mesh of the vibrating screen 2.

Such a beating net 4 is fixed to the back surface 5b of the thin strip fixing plate 5 only at the lower position of the thin strip fixing plate 5 (see FIG. 2), and the adjacent thin strip fixing plates 5, 5 are provided. In the range between 5 is not connected (fixed) to the lower side of the vibrating screen 2 (see FIG. 1). More specifically, the synthetic resin vertical lines 4b (4b′, 4b″) of the beating net 4 located below the thin strip fixing plate 5 are heat-welded to the lower surface 5b of the thin strip fixing plate 5. The other vertical lines 4b made of synthetic resin, which are fixed, are not connected to the vibrating screen 2 under the vibrating screen 2 and are in a free state. A certain gap is formed between the synthetic resin horizontal line 2a of the vibrating screen 2 and the synthetic resin vertical line 4b of the tapping net 4.

Therefore, when the vibrating screen mesh 1 with the clogging prevention function is stretched over a vibrating screen device 7 (described later) as shown in FIG. 4 to vibrate the device, the thin strip fixing plates 5, 5 are used. The beating net 4 between them vibrates in the vertical direction (direction of arrow D), and when vibrated upward, it abuts against the above vibrating screen 2 on the upper side and beats it, and as a result, for the vibrating screen. It is possible to eliminate the clogging of the net 2. When the beating net 4 moves upward, it directly hits the synthetic resin horizontal line 2a below the vibrating screen 2.

Further, the portion (vertical portion) of the beating net 4 corresponding to the lower central portion 5c of each of the thin strip fixing plates 5 is removed (see FIGS. 2 and 4), whereby Fitting recesses 5d, into which the heads 10a of the rubber cushions 10 are fitted, are formed in the lower central portion 5c (see FIGS. 1 and 2). Then, in a state where the head portion 10a of each of the anti-vibration rubbers 10 is fitted into each of the fitting recessed portions 5d (see FIGS. 1 and 4), each of the head portions 10a is on the lower surface of each of the thin plate-shaped fixing plates 5. It is configured so that it can abut against 5b.

That is, in the hitting net 4, conventionally, all the portions corresponding to the lower side of the thin plate-shaped fixing plates 5 are connected to the lower surface 5b of the thin plate-shaped fixing plates 5 by heat welding. .. In the present invention, by removing the beating net 4 in the portion corresponding to the lower central portion 5c of each thin plate-shaped fixing plate 5, the lower central portion 5c of each thin plate-shaped fixed plate 5 is removed. The fitting recesses 5d for fitting the anti-vibration rubber 10 are formed.

Therefore, the beating net 4 is fixed to the thin strip in which the vertical line 4b made of synthetic resin (the upper surface of the vertical line 4b' made of synthetic resin in FIGS. 1 and 2) along one vertical edge 4c is one. A vertical line 4b made of synthetic resin (in FIG. 1 and FIG. 2, a vertical line made of synthetic resin in FIG. 1 and FIG. 2) is fixed by thermal welding to the corresponding lower edge 5'of the plate 5 in the vertical direction and along the other edge 4c' in the vertical direction. The upper surface of the line 4b″ is fixed to the corresponding lower lower edge 5″ of the other thin plate-shaped fixing plate 5 adjacent to the one thin plate-shaped fixing plate 5 by heat welding.

In FIG. 1, the synthetic resin vertical lines 4b′ and 4b″ fixed to the thin strip fixing plates 5 and 5 of the tapping net 4 are compared with other synthetic resin vertical lines 4b. Although the cross section is rectangular and has a large cross section, the synthetic resin vertical lines 4b′ and 4b″ may be the same as the other synthetic resin vertical lines 4b. By making the cross-sectional area rectangular like the synthetic resin vertical wires 4b′ and 4b″ and making the cross-sectional area larger than the other synthetic resin vertical wires 4b, the depth of the fitting recess 5d can be increased. This is advantageous in that the support by the vibration isolating rubber 10 is stable.

In the vibrating screen mesh 1 with the clogging prevention function, as shown in FIGS. 6 and 8, both edges 2a′ and 2a′ of the synthetic resin horizontal wire 2a are in opposite directions (arrows B and B′ directions). In the stretched state, the vibrating screen device 7 is stretched between a pair of parallel vibrating upright plates 6 and 6 ′, and the middle part of the portion of the tapping net 4 fixed to the thin strip fixing plates 5 and 5. The anti-vibration rubber 10 on the support rod 11 is fitted and abutted on the (fitting recess 5d). In addition, in FIG. 6, reference numeral 8 is a fixing horizontal rod for fixing the support rod 11. Incidentally, as described above, a plurality of the vibration isolating rubbers 10 may be provided in the vertical direction, or one vibration isolating rubber long in the longitudinal direction may be used. A plurality of the support rods 11 may be provided corresponding to the anti-vibration rubber 10 or may be a plate-shaped member that is long in the vertical direction.

Further, as shown in FIG. 7B, the cross-sectional shape (cross-sectional shape of the covering portion, vertical cross-sectional shape in the present embodiment) of the synthetic resin horizontal wire 2a of the vibrating screen 2 of the present invention is the core wire. 3, the covering portion on the lower side 22 is thicker than the covering portion on the upper side 21. In addition, what is shown in FIG. 7A is a cross-sectional shape (longitudinal cross-sectional shape) of the conventional synthetic resin horizontal wire 2a, and the core wire 3 is provided at the center of the circular cross-sectional shape. The covering portion means a synthetic resin (such as urethane) portion around the core wire 3 in the synthetic resin horizontal wire 2a.

More specifically, the cross-sectional shape of the synthetic resin horizontal wire 2a according to the present invention is such that, as shown in FIG. 7(b), the covering portion on the upper side 21 of the core wire 3 is semicircular, and the core wire is The lower covering portion 3 is formed in a substantially square shape (or a square shape) having one side in the vertical direction longer than the radius of the semicircular shape.

As an example, when the diameter of the conventional synthetic resin horizontal wire 2a in FIG. 7A is 1.6 mm and the diameter of the core wire is 0.35 mm, for example, the thickness of the covering portion of the synthetic resin horizontal wire 2a is It becomes 0.625 mm. The diameter of the core wire of the synthetic resin horizontal wire 2a according to the present invention is 0.35 mm, which is the same as the conventional one, and the thickness of the covering portion on the upper side 21 of the core wire 3 is 0.625 mm, which is the same as the conventional one. The wall thickness of the covering portion is larger than the conventional wall thickness, for example, the vertical wall thickness is 1.425 mm. Therefore, the width of the synthetic resin horizontal wire 2a in the vertical direction is about 2.4 mm.

The cross-sectional shape of the cover 22 on the lower side 22 of the synthetic resin horizontal wire 2a has a longitudinal width of, for example, 1.6 mm, which is the same as the diameter of the conventional synthetic resin horizontal wire 2a, but the lower end has both corners. 23 and 23 are configured to have a substantially rectangular cross section with a right angle.

By vibrating, the beating net 4 comes into contact with the horizontal line 2a made of synthetic resin on the lower side of the vibrating screen 2 from the lower side to perform tapping, but the core wire of the horizontal line 2a made of synthetic resin is used. Since the thickness of the covering portion on the lower side 22 is larger than 3, the core wire 3 can be easily exposed from the covering portion of the synthetic resin horizontal wire 2a even when the tapping is repeated. There is no.

As shown in FIG. 9, in the vibrating screen device 7, the vibrating upright plates 6 and 6 ′ are vibratably supported by the supporting devices 12 and 12 on the stationary machine frame 21 installed on the ground G. A stationary machine frame 13 for a motor is installed on the ground G, and a driving motor M is fixed on the machine frame 13. A vibrator 14 is provided on the vibration upright plates 6 and 6', and a drive belt 15 is wound around a rotating body 14a of the vibrator 14 and a pulley P of the motor M.

An eccentric weight (not shown) is fixed to the drive shaft of the rotating body 14a of the vibrator 14, and the vibrator 14 vibrates by driving the motor M to rotate the rotating body 14a. By vibrating the vibrating upright plates 6 and 6', the vibrating screen mesh 1 with the clogging prevention function stretched between the vibrating upright plates 6 and 6'(indicated by a chain double-dashed line in FIG. 7). Can be vibrated.

The direction of vibration is, for example, as shown by arrow C in FIG. 9, vibration along an elliptical orbit around a central axis Q inclined by 45 degrees with respect to the vertical, and along the elliptical orbit, the clogging occurs. The vibrating screen mesh 1 with the prevention function vibrates.

The left and right ends of the vibrating screen mesh 1 with the clogging prevention function are fixed between the vibrating upright plates 6 and 6', as shown in FIG. Since the fixing structure of the left and right side edges of the vibrating screen net 1 with the clogging prevention function is bilaterally symmetrical, only the left fixing structure will be described with reference to FIG. In the figure, an L-shaped angle 19 is fixed to the inside of the vibration upright plates 6 and 6 ′, and an upper portion 16 a of the clapping bar 16 is used as a fulcrum at the upper portion of the L-shaped angle 19 and the lower end portion 16 b is set to the above. The tension bolts 17 are arranged so as to face the angle 19, and the tension bolts 17 are provided obliquely from the inside of the clapping bar 16. The end portions of the tension bolts 17 penetrate the vibration upright plate 6 and the vibration upright plate 6. It is fixed by a nut 18 on the outer side of.

In such a structure, hooks 20 are fixed to the left and right edges (both ends 2a' of the synthetic resin horizontal wire 2a) of the vibrating screen mesh 1 with the clogging prevention function. Of the pair of vibration upright plates by engaging the hooks 20 between the lower end 16b and the upper surface 19a of the L-shaped angle 19 by engaging the lower end 16b of the L-shaped angle 19 with the tension bolt 17 and screwing in the tension bolt 17. The vibrating screen mesh 1 with the clogging prevention function is stretched between 6 and 6'. Then, the tension bolt 17 is screwed in to apply tension to the vibrating screen 1 in the directions of arrows B and B'.

Then, as shown in FIG. 6, in a state in which tension in the opposite direction (arrow B, B′ direction) is applied to the vibrating screen mesh 1 with the clogging prevention function, it is positioned below the vibrating screen mesh 2. A plurality of support rods 11 are erected from the lower side of the vibrating screen mesh 2 at the corresponding positions of the fitting recesses 5d of the thin strip-shaped fixing plate 5 on the fixing horizontal rod 8. The anti-vibration rubber 10 is fixed to the upper part of each of the vibration-proof rubbers 10 in the fitting recess 5d below the thin strip fixing plate 5 of the vibrating screen net 1 with the clogging prevention function. Fit and abut from the lower side of the sieve screen 2. By forming the center support rod 11 to be slightly longer than the support rods 11 on both sides, the central portion of the vibrating screen 1 is slightly lifted upward so that tension is applied upward in the vibrating screen 1. Then, the whole of the vibrating screen 1 is stretched so that the center of the vibrating screen 1 is slightly raised (convex upward) (see FIG. 6).

At this time, the arc toward the upper side of the vibrating screen 2 is formed with a fitting recess 5d of the vibration isolating rubber 10, and the upper and lower parts of the vibrating screen 2 at the contact portion of the vibration isolating rubber 10 are formed. Since the directional width (width t3 in FIG. 4) is thin, it is configured so that the circular arc is gentler than the conventional upward arc of the vibrating screen 2 (see FIG. 6). .. This makes it possible to minimize uneven distribution of the objects to be sieved to both sides of the vibrating screen 2 (both sides having a height lower than the center of the vibrating screen 2).

In the vibrating screen device 7 (see FIG. 9), a raw material (screening object) such as an aggregate is introduced from the inlet 7a, and in the device 7, vibration with a clogging prevention function is shown as indicated by a chain double-dashed line. A sieve screen 1 is installed. Then, the raw material charged from the inlet 7a is subjected to a sieving operation in the vibrating screen 1 with the clogging prevention function, and the raw material (screening object) on the screen 1 advances in the direction of the arrow I and from the outlet 7b. It is configured to be discharged in the direction of arrow F.

Since the vibrating screen net 1 with a clogging prevention function of the present invention is configured as described above, both ends 2a′, 2a′ of the vibrating screen net 1 with a clogging prevention function according to the present invention are shown in FIG. As shown in FIG. 5, the vibrating screen device 7 is stretched between the vibrating upright plates 6 and 6 ′. In this case, as shown in FIG. 8, the hooks 20 at both ends of the vibrating screen mesh 1 with the clogging prevention function are engaged with the clapping bar 16 and the tension bolts 17 are screwed in, so that arrows B, B in FIG. The tension is applied in the same direction by pulling in the "direction", and the vibration upright plates 6 and 6 are stretched in the right and left opposite directions (left and right directions). The fixed portions at both ends of the vibrating screen mesh 1 with the clogging prevention function are indicated by reference numerals 24 and 24' (see FIG. 6).

Further, the heads 10a of the anti-vibration rubbers 10 are fitted and inserted into the fitting recesses 5d on the lower side of the thin strip-shaped fixing plates 5 on the lower side of the vibrating screen net 2, respectively. Is brought into contact with each lower surface 5b of each thin plate fixing plate 5.

At this time, since the height of the central vibration-proof rubber 10 fixed on the fixing horizontal rod 8 is slightly higher than the height of the left and right vibration-proof rubbers 10, 10, the net 1 for the vibrating screen with the clogging prevention function is provided. As described above, in the state of being pulled in the opposite directions to the left and right, the central portion thereof is further pulled upward (tension is also applied upward), and as a whole, in the state of an upward convex arc, It is in a state of being stretched between the vibration upright plates 6 and 6.

At this time, the upwardly convex arc has a fitting recess 5d formed on the lower surface side of the thin strip fixing plate 5, and the head 10a of the anti-vibration rubber 10 is fitted into the fitting recess 5d. Since the vertical height t3 (see FIG. 4) of the vibrating screen net 1 with the clogging prevention function in the fitting recess 5d of the vibration isolating rubber 10 is narrower (thinner) than the conventional one, The upwardly convex arc is gentler than in the conventional case (the positions of the fixing portions 24 and 24' do not change. See FIG. 6). Therefore, uneven distribution of the vibrating screen 2 of the sieve to the left and right is prevented as much as possible. can do.

In the tensioned state, the motor M is driven to vibrate the vibrating upright plates 6 and 6'along the elliptical orbit in the arrow C direction. Then, as shown in FIG. 4, the vibrating screen 2 on the upper side of the vibrating screen 1 with a clogging prevention function vibrates along the elliptical orbit, and the beating net 4 is combined with the vibration-proof rubber 10. Between the anti-vibration rubber 10 and the anti-vibration rubber 10, the central portion is vibrated in the vertical direction (direction of arrow D) with the largest amplitude (stroke), and is tapped over substantially the entire lower side of the vibrating screen 2. Repeat. At this time, the anti-vibration rubbers 10 are fitted in the fitting recesses 5d on the lower surface of the thin strip fixing plate 5, and the vibrating screen 2 has a tension in the left-right direction (opposite left-right direction) and upward. It is in a state of being applied. Therefore, the vibration damping rubbers 10 are in a state in which the heads 10a are strongly in contact with the fitting recesses 5d and the lower surface 5b of the thin strip fixing plate 5, so that both the vibration upright plates 6 and 6'. Vibrates in the direction of arrow C, and even if the entire vibrating screen mesh 1 with the clogging prevention function vibrates in the direction of arrow C, the anti-vibration rubbers 10 are fitted in the fitting recess 5d of the thin strip fixing plate 5. The fitted state is maintained, and therefore, together with the upright plates 6 and 6', the vibrating screen mesh 1 with the clogging prevention function, the anti-vibration rubbers 10, the support rods 11, and the fixing horizontal rods 8 are integrated. Vibrates.

The orbit of vibration is not limited to the above elliptical orbit, and various types of vibration such as a circular orbit, a vibration along a vertical straight line trajectory, and a vibration along a diagonal vertical straight line trajectory can be considered.

In this state, for example, aggregate is introduced through the inlet 7a of the vibrating screen device 7. The aggregate that is put into the mesh 1 from above the vibrating mesh 2 drops onto the vibrating mesh 2 and the sieve operation is performed by the vibration along the elliptical orbit of the vibrating mesh 2. .. That is, aggregates smaller than the mesh of the vibrating screen 2 pass through the vibrating mesh 2 and are downwardly accumulated, and aggregates larger than the mesh are indicated by arrows on the vibrating screen 2. It moves in the direction I, moves in the direction of the arrow F from the outlet 7b, and is transferred by a conveyor not shown. With this operation, the vibrating screen 2 can be used for sieving.

Here, the beating net 4 constantly vibrates in the vertical direction on the lower surface of the vibrating screen 2, so that the upper surface of the beating net 4 constantly hits a wide area of the lower surface of the vibrating screen 2. Therefore, even if fine particles adhere to the squares of the vibration net 2 and block the squares, the squares are immediately struck from below by the smashing net 4, so that the particles that block the squares are Due to the vibration of the tapping, it immediately separates from the grid and falls and accumulates downward.

Since the size of the mesh of the beating net 4 is larger than the size of the mesh of the vibrating screen 4 (for example, 16 times the size), the particles separated from the mesh of the vibrating screen 2 are the beating mesh 4. It is possible to easily pass through the squares and fall down and accumulate.

Further, the tapping net 4 repeats tapping from the lower side to the synthetic resin horizontal line 2a below the vibrating screen net 2, and the synthetic resin horizontal line 2a is shown in FIGS. As shown in FIG. 7( b ), since the thickness of the covering portion on the lower side 22 of the core wire 3 is large, the core wire 3 is not easily exposed from the covering portion, The use of the vibrating screen 2 can be continued for a long period of time, and the life of the vibrating screen 2 and thus the vibrating screen 1 with a clogging prevention function can be extended.

Further, since the cross-sectional shape of the synthetic resin horizontal wire 2a below the core wire 3 is configured such that the corner portions 23, 23 are at right angles (see FIG. 7(b)), the beating net 4 is in contact. Even if the core wire 3 moves downward from the position shown in FIG. 7(b) due to the contact, the core wire 3 has a shape that is hard to be exposed from the covering portion of the synthetic resin horizontal wire 2a. The life can be extended.

As described above, the present invention vibrates by vibrating the mesh screen 1 for vibrating screen with clogging prevention function by fixing both ends of the horizontal line 2a made of synthetic resin to the fixing members such as the pair of vibrating upright plates 6 and 6'. A vibrating net with an upper clogging prevention function in a state in which it is stretched on the sieve device 7 and the lower side corresponding to the thin strip fixing plate 5 is supported by a supporting member (for example, a vibration-proof rubber 10 and a supporting rod 11). When 1 is vibrated, the beating net 4 between the thin strip-shaped fixed plates 5 vibrates in the vertical direction with its central portion as the maximum stroke, and beats the lower side of the vibrating screen 2 so that the vibrating screen is made. The second clogging can be effectively prevented.

Further, since the vibrating screen 2 and the beating screen 4 are integrated, even if the vibrating screen 1 with a clogging prevention function is installed on the vibrating screen device 7 with an inclination, the spheres are unevenly distributed as in the conventional case. And the clogging prevention function does not deteriorate.

Further, the fitting recess 5d is formed on the lower side of the thin strip fixing plate 5, and the head 10a of the supporting member (for example, the vibration-proof rubber 10 or the like) is fitted into the fitting recess 5d. The upper and lower thickness of the vibrating screen 2 at the contact position of the vibrating screen 2 can be reduced, and when the vibrating screen 1 with the clogging prevention function is stretched on the vibrating screen device 7, The convex arc can be formed more gently than in the conventional device, and uneven distribution of the sieve target to the left and right can be prevented as much as possible.

Further, since the synthetic resin horizontal wire 2a on the lower side of the vibrating screen 2 is configured so that the wall thickness 22 on the lower side of the core wire 3 is larger, the life of the vibrating screen 2 can be kept longer. ..

When the vibrating upright plates 6 and 6'are vibrated vertically or obliquely up and down, including the elliptical locus, etc., the beating net 4 between the thin plate-shaped fixed plates 5 vibrates vertically with the central portion as the maximum stroke. However, since the lower side of the vibrating screen 2 is tapped, it is possible to realize a vibrating screen device that can effectively prevent clogging of the vibrating screen 2.

The vibrating screen mesh with a clogging prevention function according to the present invention can make a convex arc gentle on the vibrating screen when the vibrating screen is stretched on the vibrating screen device, and for the vibrating screen. It is expected to be widely used because it can keep the life of the net long.
