Best Mode of Carrying out the InventionBest Mode of Carrying out the Invention

The combine comprises a chassis carrying a threshing cylinder 1 between the front drive wheels 2 and a crop collecting table 3 that is connected to the chassis so as to pivot about the axis of rotation of the cylinder 1. Crop fed to the cylinder by the table is threshed between the cylinder and an open grate concave 4. Straw from the rear of the cylinder passes onto straw walkers 5 that operate to move the straw rearwards and free loose grain from it in the process. This grain falls onto a grain pan 6 that reciprocates so as to feed grain forward onto a further grain pan 7 that reciprocates so as to feed the grain rearwards to a shaker shoe 8.The combine comprises a chassis carrying a threshing cylinder 1 between the front drive wheels 2 and a crop collecting table 3 that is connected to the chassis so as to pivot about the axis of rotation of the cylinder 1.

This grain falls onto a grain pan 6 that reciprocates so as to feed grain forward onto a further grain pan 7 that reciprocates so as to feed the grain rearwards to a shaker shoe 8.

Grain that falls through the concave 4 collects on a continuous band-type elevator 9 that carries it upwards and drops it onto the front of the pan 7 beneath the straw walkers. A pre-cleaning fan 10 is located beneath the elevator 9 and directs a blast of air rearwards through the gap between the elevator and pan 7 so as to clean the grain falling from the elevator. This air blast passes rearwards between the straw walkers 5 and pan 6 and performs a further cleaning action upon the grain falling from the straw walkers. Air also passes rearwards between the grain pans 6 and 7 and performs a further cleaning action on the separated grain falling from pan 6 onto pan 7.Grain that falls through the concave 4 collects on a continuous band-type elevator 9 that carries it upwards and drops it onto the front of the pan 7 beneath the straw walkers.

Air also passes rearwards between the grain pans 6 and 7 and performs a further cleaning action on the separated grain falling from pan 6 onto pan 7.

The shaker shoe 8 comprises two sieves 11, a fan 12 that blows air into the shoe across and through the sieves, a grain collection auger 13 that delivers grain from the bottom of the shoe to the grain tank 14, and a grain return auger 15 that collects tailings from the rear of the sieves and feeds this to a paddle type re-thresher 16 that threshes the tailings and delivers them onto the pan 6.The shaker shoe 8 comprises two sieves 11, a fan 12 that blows air into the shoe across and through the sieves, a grain collection auger 13 that delivers grain from the bottom of the shoe to the grain tank 14, and a grain return auger 15 that collects tailings from the rear of the sieves and feeds this to a paddle type re-thresher 16 that threshes the tailings and delivers them onto the pan 6.

It will be appreciated that the pre-cleaning action of the fan 10 makes the cleaning process in the shaker shoe easier and allows a gentler fan 12 to be used therein so as to reduce air generated grain losses to a minimum. The speed of each fan.10 and 12 may be adjustable to vary the action of each.It will be appreciated that the pre-cleaning action of the fan 10 makes the cleaning process in the shaker shoe easier and allows a gentler fan 12 to be used therein so as to reduce air generated grain losses to a minimum.

Grain in the grain tank 14 is discharged through a discharge pipe 17.Grain in the grain tank 14 is discharged through a discharge pipe 17.

In an alternative embodiment of the invention in which the relative height of the concave 4 and shaker shoe 8 permits, the elevator 9 may be replaced by a conveyor such as a grain pan that is reciprocated to feed grain rearwards.
