Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for installing a sieve screen in a vibrating sieve machine.

[Conventional technology and its problems]

Although the vibration drive source is not shown in Fig. 6,
Mounting angle members 2a, 2b are fixed (for example, by welding) to both inner walls of the vibrating frame 1 in the longitudinal direction (the direction of material transfer).Auxiliary angle members 3a, 3b are also fixed (for example, by welding) to both inner walls of the vibration frame 1. is the vibration frame 1
is fixed between the inner end walls of the A sieve net 4 is placed on top of these, and a pressing band material 5
a, 5b, 6a, 6b as angle members 2a, 2
b, 3a, 3b (with the sieve net 4 in between), insert bolts 7 into a number of holes formed along the longitudinal direction of these, and screw nuts 8 into these. By tightening the sieve net 4
are attached to the angle members 2a, 2b, 3a, 3b, that is, to the vibrating frame 1, but replacing or removing the sieve screen 4 requires a lot of effort. This is because a large number of bolts and nuts must be removed and installed.

In addition, even after installation, the bolt heads and the holding strip protrude from the mesh surface, and as the material flows over them many times, these members wear out. If the flowing material is sticky, the material will adhere and grow around those parts.
This may also cause clogging of the sieve screen.

[Problem that the invention seeks to solve]

The present invention was made in view of the above-mentioned problems, and it facilitates the work of removing or replacing the sieve screen, eliminates the wear of bolts, holding members, etc., and eliminates the problem of clogging of the sieve screen even when the material is sticky. An object of the present invention is to provide a method for installing a sieve screen in a vibrating sieve machine that prevents the occurrence of

[Means for Solving the Problems] The above object is to form the sieve net at least partially from a material that is elastically deformable; and to attach a mounting member to the vibrating frame in order to mount the sieve net inside the vibrating frame. fixing; forming an engaging portion in the elastically deformable portion of the sieve net so that the sieve net and the attachment member engage; and engaging the sieve net and the attachment member at the engagement portion; and a wedge receiving portion is formed in the engaging portion, and a wedge member is driven into the receiving portion to elastically attach the sieve net to the mounting member. This is achieved by the installation method.

[Effect]

When the wedge member is driven into the wedge-receiving portion of the sieve net, the engaging portion of the sieve net is elastically deformed, and this restoring force allows the sieve net to be attached to the attachment member at this portion.

There is no need to remove and install a large number of bolts as in the past, and if the wedge member is made into a band-like member that spans the entire width of the sieve screen (accordingly, the wedge receiver also becomes a long one that spans the entire width), the installation work becomes easier. It will also be easier.

When driving the wedge member into the wedge receiving part, the surface of the sieve mesh and the top surface of the wedge member can be made flush, so the protruding part on the surface of the sieve mesh can be eliminated, which reduces the wear and tear of the bolts that conventionally occur. There is no longer a problem of staining, and no clogging of the sieve screen even when the material is sticky.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 5.

In the figure, the vibrating sieve machine of this embodiment is indicated as a whole by 10, and vibrating electric motors 13a, 13b are attached to a pair of vanes 12, 12 fixed to the bottom of a trough 11 serving as a frame. A sieve net 17 made of rubber is stretched inside the trough 11, and these are attached to a plurality of mounts 18 by wedge members 19 in a manner to be described later. The material on the sieve screen 17 is passed through the first discharge port 1.
The material under the sieve is discharged from the second discharge port 15.
discharged from. Trough 11 is coil spring 1
It is suspended from a part of the building by 6 and 16.

As clearly shown in FIGS. 3 and 4, each mount 18 includes a metal tube 20, a pair of strips 21a,
21b, which extend in the width direction of the trough 11 and are fixed to both inner walls of the trough 11 by welding. Alternatively, it may be fixed with bolts, although not shown. Band material 21
a and 21b are arranged in an "eight" shape, and their lower ends are welded to the pipe material 20.

A large number of small holes 22 are formed in the sieve net 17,
The material is sieved by this, and engaging protrusions 23, 23, . Each of these consists of a pair of inner protrusions 23a, 23b and outer protrusions 23c, 23d; these protrusions 23a, 23b, 23c, 23
d extends across the width of the trough 11.
As clearly shown in FIG. 4, the lower ends of the inner protrusions 23a and 23b are thick, and the outer protrusions 23
c and 23d extend in an "eight" shape so as to be able to come into elastic contact with the strips 21a and 21b of the mounting base 18. In addition, the inner protrusions 23a, 23b and the outer protrusion 2
Between 3c and 23d is the strip 21 of the mounting base 18.
Recesses 25a and 25b are formed to receive the upper end portions of the recesses 25a and 21b in an elastically pressed state. Furthermore, a slit-shaped groove 26 extending in the width direction of the trough 11 and serving as a wedge receiving portion is formed between the pair of inner protrusions 23a and 23b. Third
As shown in the figure, when the sieve net 17 is attached, the band-shaped relatively hard rubber wedge member 19 is
It is elastically press-fitted into this groove 26. The upper surface of the wedge member 19 is flush with the upper surface of the sieve net 17.

Although the vibrating sieve machine of this embodiment is constructed as described above, the operation of attaching the sieve net 17 to the mounting base 18 will be explained next with reference to FIGS. 4 and 5.

Both inner walls of the trough 11 are provided with pipe members 2 at both ends thereof.
0 and strips 21a and 21b are fixed across the trough 11 in the width direction. A rubber sieve net 17 is placed on this so that its inner protrusions 23a, 23b and outer protrusions 23c, 23d engage with the strips 21a, 21b as shown in FIG. .
The sieve net 17 is automatically positioned within the trough 11 by the engagement as described above.

Next, a band-shaped wedge member 19 made of relatively hard rubber is driven into the wedge receiving portion 26 of the sieve screen 17 from above. In this driving, the wedge member 19 is first inserted into the wedge receiving part 26 by hand, and then the wedge member 19 is driven by a wedge driving tool having a surface with a width larger than the thickness t of the wedge member 19. 19 is press-fitted between the lip-shaped inner protrusions 23a, 23b by pushing them apart, and connecting the inner protrusions 23a, 23b and the outer protrusion 23.
c, 23d between the strips 21a, 2 of the mounting base 18.
The upper end portion of 1b is pinched. Therefore, as shown in FIG. 3, the sieve screen 17 is firmly supported on the mounting base 18. Since the width of the driving surface of the wedge driving tool is larger than the thickness t of the upper surface of the wedge member 19,
If it is driven in so as to cover this upper surface, the upper surface of the wedge member 19 and the upper surface of the sieve net 17 will be flush with each other, as shown in FIG.

The sieve net 17 is firmly supported on the mounting base 18 in the above manner.
8 and simply drive in the wedge member 19, the installation work is extremely simple.
A plurality of wedge members 19 must be driven in depending on the number of mounting bases 18, but since the mounting base 18 spans the entire width of the trough 11, it is sufficient to drive one strip-shaped wedge member 19 into it; Even if the mounting bases 18 are not provided at such small pitches in the longitudinal direction (perpendicular to the width) of the trough 1, the sieve net 17 can be firmly fixed to the trough 11 (in the width direction, the mounting bases 18 This is because it can be held continuously.

When the vibrating electric motors 13a and 13b are driven, the trough 11 vibrates in the direction of the arrow shown in FIG. 1, and the material on the sieve net 17 (not shown) is sieved while being transferred to the left on the sieve net 17. At this time, the wedge member 19 and the upper surface of the sieve net 17 are flush with each other, and there is nothing protruding on the sieve net 17, so the material is not attached to the protruding portions (bolts, holding strips, etc.) as in the past. I never stagnate. Therefore, there is no need to wear these out. This means that the attachment means of the sieve screen are not worn away by the transferred material. This makes it possible to stabilize the attachment condition for a longer period of time than in the past. Moreover, since there are no protrusions, even if the material is sticky, there is no possibility that such protrusions will adhere to and grow and clog the sieve mesh 17.

Next, a case where the sieve screen 17 is removed or replaced will be explained.

In this case, the upper surface of the wedge member 19 in the state shown in FIG. 3 may be driven into the upper surface of the wedge member 19 in the state shown in FIG. The wedge member 19 is pushed downward while further expanding the inner protrusions 23a, 23b of the sieve screen 17. Finally, as shown in FIG. 5, it is dropped into the space S below the inner protrusions 23a and 23b formed by the tube 20 and the strips 21a and 21b. Thereafter, the sieve screen 17 can be easily removed from the mounting base 18 by lifting the sieve screen 17 upward. and each wedge member 1 in the space S
You can take out 9 by hand. The installation work for a new sieve screen is similar to that described above.

Since each wedge member 19 only needs to be driven down as described above, the work of removing the sieve net 17 is also extremely simple. Previously, a large number of bolts and nuts had to be removed.

Although the embodiments of the present invention have been described above, the present invention is of course not limited thereto, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiment, the entire sieve net 17 is made of rubber, but only the portion that engages with the mounting base 18 may be made of rubber. For example, the other portion may be made of metal, and a rubber material serving as the engaging portion may be adhered to this.

Further, in the above embodiment, the wedge member is the trough 11.
Although the strip material is used to cover the entire width of the sieve, it is also possible to use a pin-shaped strip material instead, and to form a round hole in the portion of the sieve screen that receives the strip material. It is clear that this method also produces better effects than the conventional method.

〔Effect of the invention〕

As described above, according to the method of attaching the sieve net in the vibrating sieve machine of the present invention, the sieve net can be easily attached and detached, and since there is no member protruding from the top surface of the sieve net, such a thing can be worn out. I never do. Therefore, even if the material is sticky, clogging of the sieve screen due to protrusions is prevented.
