Background

Be applied to the metallurgy among the prior art, cantilever bar in mine, the coal dressing trade is as shown in fig. 1, has trompil 11 around the square pipe 1, and cantilever bar body 2 passes square pipe 1 through trompil 11, and square pipe 1 is inside to be equipped with to pass square pipe 1 to the tight bolt 3 in cantilever bar body 2 top, is equipped with the clamp plate that increases area of contact and the rubber pad 4 of buffering between bolt 3 and the cantilever bar body 2. However, the structure is not only complex, but also cumbersome in the assembly process; the most important is that the vibration source is transmitted to the cantilever bar body 2 through the square tube 1, so that the free end of the cantilever bar body 2 forms secondary vibration. However, the prior art structure has a large number of fastening points to the cantilever bar, so that the amplitude is affected, and if a larger amplitude is required, a larger energy output is required. Because for some particles which are small in particle size and are easy to be wet and bonded, the existing structure cannot meet the screening effect, and bonding on parts is caused.

SUMMERY OF THE UTILITY MODEL

For solving among the prior art cantilever bar amplitude little, can't satisfy the problem that the granule is normally sieved to be stained with easily that the particle diameter is little, the utility model provides an avoid the screen cloth structure who glues the net.

The utility model discloses a realize through following technical scheme:

a screen mesh structure for preventing net sticking comprises a bar support, polyurethane filling and a cantilever bar body; the rod support piece is provided with an inner cavity, and one end of the cantilever rod body extends into the inner cavity of the rod support piece and is fixedly connected with the rod support piece; the polyurethane is filled and poured in the inner cavity of the bar supporting piece at the periphery of the cantilever bar body.

According to the excellent characteristics of polyurethane filler material possess good elasticity, ageing resistance and shock-absorbing capacity to cantilever stick strip body formation support in the stick support piece to cantilever stick strip mounting structure is complicated among the solution prior art, installation complex operation and cantilever stick strip body secondary amplitude are little problem, and then solve the applicable to easily being stained with wet granule screening.

The utility model discloses a further improvement still, above-mentioned stick support piece's cross-section is the U-shaped, and stick support piece opening direction towards the extending direction of cantilever stick body free end.

Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments, and obviously, the embodiments described below are only some embodiments, not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments in this patent without making creative efforts, shall fall within the protection scope of this patent.

As shown in the attached drawings, the screen mesh structure for preventing the screen mesh from being stuck comprises a bar support part 5 and a plurality of cantilever bar bodies 2 which are arranged on the bar support part 5 in parallel; the whole bar supporting piece 5 is in a long strip shape, the length direction of the bar supporting piece 5 is perpendicular to the opening direction of the bar supporting piece, and the plurality of cantilever bar bodies 2 are arranged in parallel in the bar supporting piece 5. The screen cloth is formed by a plurality of cantilever bar bodies 2 arranged in the bar support member 5 together, and under the driving of a vibration source, the free ends of the cantilever bar bodies 2 generate secondary vibration to realize the screening of particles.

The bar support member 5 is provided with an inner cavity, and one end of the cantilever bar body 2 extends into the inner cavity of the bar support member 5 and is fixedly connected with the bar support member 5; the polyurethane filling 6 is poured into the inner cavity of the bar support 5 at the periphery of the cantilever bar body 2. The inner wall of the bar support 5 and the cantilever bar body 2 are coated with an adhesive in contact with the polyurethane filling 6. By applying the adhesive, the strength of the connection between the adjacent members is increased. The Shore A hardness of the polyurethane filling 6 is 70-80. The amplitude of the cantilever bar body 2 is controlled by controlling the hardness coefficient of the polyurethane filler 6 itself. Fill 6 characteristics that the material possesses good elasticity, ageing resistance and shock-absorbing capacity are superior according to polyurethane and form the support to cantilever stick strip body 2 in stick support piece 5 to cantilever stick strip mounting structure is complicated among the solution prior art, installation complex operation and the little problem of 2 secondary amplitudes of cantilever stick strip body, and then solve the applicable to easily being stained with wet granule screening.

The cross section of the bar support member 5 is U-shaped, and the opening direction of the bar support member 5 faces the extension direction of the free end of the cantilever bar body 2. The U-shaped open bar support 5 provides structural support for the amplitude increase of the cantilever bar body 2.

The bar support member 5 is provided with a through hole 51 opposite to the opening, one end of the cantilever bar body 2 penetrates through the through hole 51 and is exposed outside the bar support member 5, and a connecting mounting point for fixing the cantilever bar body 2 is arranged on the periphery of the through hole 51 on the outer wall of the bar support member 5. The cantilever bar body 2 sequentially passes through the inner cavity of the bar support member 5 and the through hole 51 and extends to the outside to be exposed and fixed, the length of the cantilever bar body 2 is prolonged, and the excessive amplitude of the free end of the cantilever bar body is avoided.

The amplitude range of the cantilever bar body 2 at the opening of the polyurethane filling 6 close to the opening is 3.8-4.2mm. After limiting the amplitude range, the screening effect of the particles which are easy to wet and adhere and have the particle size of about 3mm is realized, and the particles are prevented from adhering to the cantilever bar body 2.

The length of the cantilever bar bodies 2 is distributed at intervals at one end far away from the bar supporting piece 5. Because the length of cantilever excellent strip body 2 free end exists differently, and for interval distribution, the amplitude that leads to cantilever excellent strip body 2's free end naturally is different to further increase the screening effect to the easy moist granule that bonds.

The working principle is as follows: in the vibration process, the section of the bar support member 5 is U-shaped, so that the vibration restriction at the bar root of the cantilever bar body 2 (i.e. the position of the cantilever bar body 2 at the U-shaped opening of the bar support member 5) is small, and in cooperation with the polyurethane filler 6 with the elastic function in the bar support member 5, the starting point of the vibration of the cantilever bar body 2 is closer to the vibration source, i.e. the bar root begins to generate effective vibration amplitude. Consequently, after the assembly, combine many cantilever excellent strip body 2 structures of length interval arrangement, just also formed the clearance of avoiding granule jamming sieve mesh (the sieve mesh is the gap that allows the granule to pass through that two adjacent cantilever excellent strip body 2 vibrations produced promptly) in excellent root department to also greatly reduced the jam problem of the little and easy moist bonding granule of particle diameter.

A avoid screen cloth structure of gluing net, possess good elasticity, ageing resistance and the superior characteristics of shock-absorbing capacity to the cantilever stick body formation support in the stick support piece according to polyurethane filler material to cantilever stick mounting structure is complicated among the solution prior art, installation complex operation and the little problem of cantilever stick body secondary amplitude, and then the solution is to being stained with being suitable for of wet granule screening easily.
