A Paddy Thresher


Updated about 2 years ago

Abstract

The present invention relates to a machine for threshing crops and more particularly for threshing paddy crops. The machine comprises of at least one pulley (16, 19} mounted on a shaft, said pulley attached to a driving engine; a threshing cylinder (18} attached to the pulley (16, 19) configured to rotate about its axis; a feeding chute (30) for feeding a crop material to the threshing cylinder; a blower (21) for separating grain from the crop material which leaves the threshing cylinder; a concave (36) mounted adjacent to the threshing cylinder for receiving grains of the crop material; and a straw outlet (37) for receiving the straw separated from the crop material.Ref: Figure 1

Specification

The present invention relates to a machine for threshing crops and more particuli"lr!y for threshing paddy  crops. The present  invention provides  a machine  that  helps in preserving straw having effective value in terms of its applications.

Background of the Invention and Related Prior Art

The currently available crop harvesting and threshing machines, which are known as combines, have reached a stage of development at which it is apparently very difficult to increase the rate and efficiency with which they can handle crop without making sncrifices in other respects. In the past, increases in output have been achieved by increasing the overall size and power of the machines. The stage has now been reached however at which the size of the machine cannot be further increased without making road transport of it impractical or illegal.

Most of the currently available self-propelled combines comprise a main body portion housing a threshing cylinder and other grain separating apparatus and having ground wheels or tracks, together with a crop gathering header which can be mounted at the front of the body portion. The header comprises a platform or table having a cutter bar or a pick-up, and an auger. In use, crop cut by the cutter bar or lifted by the pick-up is immediately conveyed inwards by the auger to a central elevator conveyor which takes the crop to the main body portion.
In the main body portion of a conventional combine, a grain crop is first threshed by a threshing cylinder at the top of the elevator and the threshed material is then passed to straw walkers which effect separation of grain from other crop material.

On account of the weight distribution in a combine arising,in part, from the presence of

the header mounted in cantilever fashion on the front end of the main body portion, the main body is almost always constructed as a front wheel drive vehicle. Also, it is generally recognized that the wheels or tracks must be of relatively large size in order to provide adequate traction for a large modern combine at the fairly low ground speeds at which such machines operate.

Consequently, the threshing cylinder of a large modern combine is located between the

wheels or tracks of the machine and this limits the overall length of the cylinder because the space between the wheels or tracks is limited, in some countries at least, by the IE"gal requirements as to maximum vehicle width.

The arrangement described above for feeding the crop into the combine and for threshing it inherently gives rise to inefficient grain separation due to the random alignment of the individual stems of unthreshed grain crop as they are presented to the threshing cylinder and to the thickness of the mat of crop which they form.

In U.K. patent specification No. 951,098 there is proposed threshing apparatl"S in wl;i_:h crop cut by a cutterbar is fed to a threshing cylinder located behind the cutterbar. The threshing cylinder extends across substantially the full width of the cutterbar.

However, the threshing apparatus proposed in U.K. patent specification No. 951,098 suffers from the disadvantage that under certain conditions insufficient separation of grain from straw occurs. The straw emerging from the thre
