Description
TECHNICAL FIELD

The present disclosure relates to an interlocking ballast system. More particularly, the present disclosure relates to the interlocking ballast system for a machine.

BACKGROUND

Machines, such as a pneumatic compactor, include a ballast chamber for receiving a ballast for increasing a weight of the machine. The ballast may include blocks made of concrete, aluminum, cast iron, steel, and so on. Additionally, the ballast chamber may be filled with water to increase the weight of the machine. The blocks may include different shapes, material, and may be arranged in various configurations with respect to one another within the ballast chamber to optimize the space within the ballast chamber and/or to achieve a required weight of the machine.

In order to increase or decrease the weight of the machine, each block may have to be individually added or removed from the ballast chamber respectively. Based on a size of the ballast chamber and/or the required weight of the machine, a number of such blocks may have to be installed or uninstalled from within the chamber. The installation/uninstallation of the blocks is a time consuming and a labor intensive process which in turn may lead to machine downtime, reduced operational efficiency, increased operational cost, and so on.

U.S. Pat. No. 5,993,110 describes a ballast system for compacting machines. The machine comprises a chassis supported on front and rear wheel-axle assemblies longitudinally spaced from each other. The chassis includes a chassis median extension located between the front and rear wheel-axle assemblies defining a raised platform. The platform includes a ballast lateral retaining means. The retaining means include a plurality of modular ballast elements fitted and locked against downward vertical and horizontal displacements by respective lateral engaging means of modular ballast elements. The engaging means are disposed transversely under the chassis median extension and include a weight that is selectively determined in function of the characteristics of a compacting load desired for the wheel-axle assemblies. Each of the modular ballast elements includes a pair of identical ballast boxes. The ballast boxes are symmetrical to the machine longitudinal axis. Each of the ballast boxes include an internal end portion provided with a central engaging means coupled to a ballast central retaining means affixed under the chassis median extension.

Currently used ballast systems for the machines are complex, expensive, and require complicated installation techniques. Hence, there is a need for an improved ballast system.

Industrial Applicability

The present disclosure relates to the ballast system 22. In the illustrated embodiment, the ballast material is filled through a first passage 76 (shown in FIG. 2) of the fourth ballast assembly 32. Due to the interlocked configuration of the ballast system 22, the ballast material flows from the fourth ballast assembly 32 into the third ballast assembly 30 via a connection interface (not shown) therebetween. The ballast material then flows from the third ballast assembly 30 into the second ballast assembly 28 via a connection interface (not shown) therebetween. Further, the ballast material flows from the second ballast assembly 28 into the first ballast assembly 26 via the connection interface 34 (shown in FIG. 3) therebetween. The ballast system 22 may be filled with a required quantity of the ballast material based on the desired weight of the machine 10. The number of the ballast assemblies and/or the vertical stacks 24 may be added or removed based on the desired weight of the machine 10 and/or a size and/or a dimension of the ballast compartment 20. Additionally, the vertical stacks 24 of the ballast system 22 may also he interlocked with one another in order to improve connection within the ballast system 22. In such a situation, the complete ballast system 22 may be filled with the ballast material through a single vertical stack 24.

In other embodiments, the ballast system 22 may include the number of ballast assemblies interlocked with one another and disposed adjacent to one another in a horizontal configuration, in another embodiment, the ballast system 22 may include only the first ballast assembly 26 having a size and/or a dimension approximately equal to the size and/or the dimension of the ballast compartment 20. In such a situation, the first ballast assembly 26 may be filled with the required quantity of the ballast material based on the required weight of the machine 10.

The first ballast assembly 26 and/or the ballast system 22 described herein may include a number of design and/or layout configurations other than the ones described herein based on application requirements without limiting the scope of the disclosure. The ballast system 22 provides a simple, convenient, cost efficient, and space efficient design of the ballast system 22. The ballast system 22 is easy to install reducing machine downtime and labor effort in turn leading to increased machine/operational efficiency, reduced costs, and so on.

While aspects of the present disclosure have been particularly shown and described with reference to the embodiments above, it will be understood by those skilled in the art that various additional embodiments may be contemplated by the modification of the disclosed machines, systems and methods without departing from the spirit and scope of the disclosure.
