BATTERY OPERATED SOIL LEVELER

Introduction:

In a continuously develop world, many things kept coming out as if there is nothing impossible anymore for something to exist. This may be part of how and why people manage to adapt to their new lifestyle. Taking a lifestyle as reason how people manage their work in less time. We know there day by day population is increased. So construction work is also increasing. When any construction area we make floor then firstly we fill there soil, pieces of stone, pieces of brick and to level this material we hammer that material. For this we use a heavy weight hammer. In this project we are making a battery operated automatic hammer.

In this project we are using dc battery to operate dc motor, the work of dc motor is to rotate the CAM. The hammer is attracted to the CAM and with the rotational movement of the CAM the hammer moves UP and Down.

METHODOLOGY BEING USED:

CAM TECHNOLOGY:

A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion or vice versa. It is often a part of a rotating wheel (e.g. an eccentric wheel) or shaft (e.g. a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path. The cam can be a simple tooth, as is used to deliver pulses of power to a steam hammer, for example, or an eccentric disc or other shape that produces a smooth reciprocating (back and forth) motion in the follower, which is a lever making contact with the cam. The cam can be seen as a device that rotates from circular to reciprocating (or sometimes oscillating) motion. A common example is the camshaft of an automobile, which takes the rotary motion of the engine and translates it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.

Displacement diagram

Certain cams can be characterized by their displacement diagrams, which reflect the changing position a roller follower (a shaft with a rotating wheel at the end) would make as the cam rotates about an axis. These diagrams relate angular position, usually in degrees, to the radial displacement experienced at that position. Displacement diagrams are traditionally presented as graphs with non-negative values. A simple displacement diagram illustrates the follower motion at a constant velocity rise followed by a similar return with a dwell in between as depicted in figure 2. The rise is the motion of the follower away from the cam center, dwell is the motion where the follower is at rest, and return is the motion of the follower toward the cam center.

However, the most common type is in the valve actuators in internal combustion engines. Here, the cam profile is commonly symmetric and at rotational speeds generally met with, very high acceleration forces develop. Ideally, a convex curve between the onset and maximum position of lift reduces acceleration, but this requires impractically large shaft diameters relative to lift. Thus, in practice, the points at which lift begins and ends mean that a tangent to the base circle appears on the profile.

APPLICATIONS

  • Base on the application of the device, I would say that it is very useful for small industrials, construction department and more.

ADVANTAGES

  • Efficiency increased

  • Time saving

  • Output fast

  • Manpower saving
