Description

SPECIFICATION Vibratory machine The invention relates to a vibratory machine with a support frame for accommodating screens, grids, conveyer elements etc. having resilient supports and drive devices.
In known vibratory machines, the load-bearing components of the vibratory machine member generally comprise longitudinal side walls and crossmembers which are connected together and are so constructed that they take up the vibratory loads occurring during operation. The size of these machines has been limited in the past, more particularly because of design problems. Attempts have been made both to manufacture large units, and to set up several smaller units together and to drive them jointly if necessary. If the individual units are constructed to be the same and for example have been provided with smooth side walls, then they could be arranged adjacent each other or one behind another in similar manner to the mechanical assembly technique.
Furthermore, it is known to construct the crossmembers as double cantilever beams in frames for sifters. Thus this vibratory machine has a relatively high transverse rigidity. The known vibratory machines do not however represent a satisfactory solution for building large units.
The present invention seeks to create a vibratory machine which may be manufactured with large dimensions.
According to the invention, there is provided a vibratory machine with a support frame for carrying screens, grids, conveyer elements etc., with resilient support and drive devices, wherein the support frame comprises a support system in lightweight construction which has rigidly connected boxshaped support elements arranged longitudinally and/or transversely of the machine.
The invention will now be described in greater detail, with reference to the schematic drawings, in which: Figure 1 shows a vibratory machine in longitudinal section, with a support frame comprising several box-shaped longitudinal members which are connected by means of cross-members.
Figure 2 shows the machine of Figure 1 in transverse section, Figure 3 shows a vibratory machine in longitudinal section, having a box-shaped support system comprising longitudinal members with integrated crossmembers and Figure 4 shows the machine of Figure 3 in transverse section.
The vibratory machine shown in Figures 1 and 2 comprises three box-shaped longitudinal members 1 to 3 which are connected together by cross members, 4 to 7, for example, welded thereto. All of the members are constructed so that they have a very high strength in the direction in which they are loaded while having a very small weight. The box shape of the support elements makes it possible to keep the wall thickness of the elements small.
Moreover, the individual elements may have openings or recesses to economize on their weight. If necessary, reinforcements strengthened areas etc.
may be provided at individual points on the support elements, for example, at the bearing points for the drive or the resilient supports.
The vibratory machine is resiliently supported on springs 8 to 10 and 11 to 13 and is driven by drive devices 14 to 22. The drive devices include drive motors 14 to 17 and appropriate exciter units 18 to 20 which are connected together by connecting elements 21, 22. The exciter units may be arranged inside or outside the box-shaped support elements 1 to 3 (see Figure 4 as well). Furthermore it is possible to build up the drive devices with the exciter units beneath the box-shaped support elements. The drive motors may all be arranged on one side of the machine.
A very rigid system of support which nevertheless has a small weight is provided by using box-shaped support elements for longitudinal and crossmembers. It is possible to manufacture machine units having particularly large dimensions longitu dinaliy and/or in the transverse direction because of this lightweight construction which has high strength. The number of longitudinal and crossmembers depends on the size of the machine. The members may be dimensioned accord- into to the size of the machine in each case or the strength requirements in each case. The support for the vibratory machine may be divided up between the resilient elements 8 to 13 in preferred manner over the entire surface of the machine.
Screens, grids, conveyer elements etc. as indicated at 25 are arranged on the vibratory frame.
Figures 3 and 4 show an embodiment of a machine in which the support elements for the longitudinal members 30 to 33 are directly connected together. The support elements may be manufactured from individual profiled sections for example welded together. Other support elements or reinforcements 26 to 28 are provided in the transverse direction. Individual ones of or all of the support elements may be used in the embodiment shown as gas channels, e.g. air channels. Thus, for example, cooling or drying airfrom a compressor (not shown) may be passed via suitable connecting lines and the support elements to the material located on the machine. The top of the support elements may have suitable openings for this purpose. The arrangement of the drives, the supports etc. corresponds largely to the arrangement according to Figures 1 and 2.
