Lining entry sheet

The inventive device relates to stone processing equipment, in particular to rubble-cleaning machines, dredges, machines for cleaning beaches.

The level is known (the drawing of CJSC Far Eastern Technology is attached, or the prospectus of Kalugaremputmutmash JSC is attached) from a similar device, where the lead-in (the first of the sheets of the lining of the gutter, onto which the bar chain feeds crushed stone), the sheet is attached to the upward; it has a certain size and configuration. The sheet is made of special alloy steel. An important sign is that it is solid.

The disadvantage of this solution is the low resource of the entry sheet, because in aggressive operating conditions (granite ballast crushed stone of the railway track exhausts the entry plate for 6-8 hours of operation of the crushed stone cleaning machine) the wear resistance of steels is insufficient.

The technical result of the proposed solution is to increase productivity. It is achieved by increasing the wear resistance of the entry sheet by means of hard alloy reinforcing its most worn section. In FIG. 1 shows the basic structure of the entry sheet, figure 2 -

view A of FIG. 1, FIG. 3 is a cross-section BB of FIG. 2, FIG. 4, 5 and 6 are versions of the entry sheet.

The entry sheet is usually fastened with screws on the ascending chute or on the body of the crushing machine.

The entry sheet is as follows. The dimensions and configuration of the input sheet 1 are similar to the known. The material of the housing 2 of the entry sheet does not matter. The material of the following sheets 3 of the lining is similar to the known. The front (from the crushed stone supply side 4) surface of the entry sheet is reinforced with carbide 5. It is technologically convenient to use carbide inserts or elements that are soldered to the housing 2.

The device operates as follows. When moving a rubble-cleaning machine or feeding a bar chain, crushed stone mainly interacts with the hard alloy of the entry sheet. The wear resistance of the carbide is higher than the wear resistance of the used steels, therefore, the entry sheet wears out less, the resource increases, less often its replacement is required and productivity increases. Thus, the reinforcement of the entry plate with carbide allows you to achieve the specified technical result.

The development of a technical result is achieved by applying protective elements 7 made of especially resistant materials (for example, high-speed or

2 hard alloyed steels). Most simply, this can be done.

surfacing.

The operation of such a lead-in sheet is similar to the work described above with the difference that the upper surface will be less susceptible to wear.

Protective elements 7 are rationally deposited by applying surfacing in the form of rolls 8 spaced apart by a certain distance a, smaller than the size of the crushed stone fraction. In this case, the rubble, moving along the front surface 6 of the entry sheet, will rarely come into contact with the material of the housing 2 and, accordingly, wear it less.

Including rolls 9 of a particularly wear-resistant material can be applied to the elements 10 (screw heads 10, recessed in the holes 11 of the sheet 1), securing the entry sheet to the machine. This will increase their resource, because Reduces wear due to contact with the chippings.

Protective rolls can be made not only in the direction of movement (rolls 7) of crushed stone along the front surface 6. They can be intersected (rolls 12). The intersection angle is not critical. The distance B between the rollers 8 should be commensurate with or exceed the distance a. This will further reduce the likelihood of gravel contact with the front surface and., Thereby increasing the life of the sheet.

Rolls 7 and 12 can be straightforward (as in figure 2), and curved, for example, in the form of a snake (figure 4). surface 14 of the base sheet, which, accordingly, leads to its wear. For

to increase the resource on the portion of the lower surface 14 adjacent to the front surface of the sheet (i.e., to carbide elements 5), it is advisable to perform rolls (similar to rollers 7 or rollers 7 and 12) or to reinforce carbide elements 13.
