Definitions

  • This invention relates to crop threshing, separating and cleaning apparatus.
  • grain that falls through the concave during the threshing action between the threshing cylinder and concave is collected on a grain pan and passed directly to a grain cleaning mechanism comprising a shaker shoe incorporating a number of sieves and a fan to direct air over and through the sieves.
  • Straw passes from the rear of the concave to a grain separating mechanism comprising straw walkers that pass the straw rearwards out of the combine and aid Separation of grain that falls onto a grain pan below the straw walkers and is delivered to the shaker shoe. Removal of chaff from the grain takes place exclusively in the shaker shoe through the action of the fan, but this may not be sufficient if there is a high chaff content.
  • crop threshing, separating and cleaning apparatus comprising a threshing cylinder and open grate concave that cooperate to thresh crop therebetween, a grain separating mechanism that receives threshed crop material from the rear of the concave and operates to separate out loose grain , a grain cleaning mechanism including sieves and a fan that remove chaff from the grain, and a pre-cleaning mechanism that is adapted to direct air through the grain to remove chaff from it as it falls in passing to the grain cleaning mechanism, characterized in that the pre-cleaning mechanism is arranged to pre-clean grain that passes through the concave and is collected by a conveyor mechanism and fed to the cleaning mechanism independently of the threshed crop material from the rear of the concave.
  • the invention therefore provides a pre-cleaning mechanism where it can be most effective in cleaning the grain alone without the. presence of straw to hinder the cleaning action.
  • the conveyor mechanism comprises a first conveyor that is arranged beneath the concave and a second conveyor arranged to receive grain dropped from the first conveyor, the pre-cleaning mechanism being arranged to direct air through the grain as it falls from the first conveyor onto the second conveyor.
  • the first conveyor may comprise a continuous belt type elevator to accommodate dropping of the grain onto the second conveyor, and the second conveyor may comprise a grain pan that feeds the grain into the grain cleaning mechanism.
  • the pre-cleaning mechanism is preferably arranged so that said air, after pre-cleaning the grain passing through concave, is used to pre-clean grain separated in the grain separating mechanism, the air being directed so that it pre-cleans grain as it falls through the grain separating mechanism, and / or pre-cleans the grain as it falls from the grain separating mechanism onto the second conveyor.
  • 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.
  • 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.
  • 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 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.
  • Grain in the grain tank 14 is discharged through a discharge pipe 17.
  • the elevator 9 may be replaced by a conveyor such as a grain pan that is reciprocated to feed grain rearwards.

Abstract

Un mecanisme de battage, separation et nettoyage de la recolte comprend un rotor de battage (1) et une grille concave ouverte (4) qui cooperent pour battre le produit de la recolte entre eux, un mecanisme de separation du grain (5) qui recoit le materiau de la recolte battue qui passe entre le rotor de battage et la grille concave, un mecanisme transporteur (9, 7) qui recupere le grain tombant au travers de la grille concave (4), un mecanisme de nettoyage du grain (18) auquel la transporteuse (9) amene le grain independamment du materiau de la recolte battue, et un mecanisme de prenettoyage du grain (10) qui dirige un courant d'air au travers du grain tombant lorsqu'il passe via le mecanisme transporteur (9, 7) vers le dispositif de nettoyage (8). Le mecanisme transporteur comprend de preference une bande transporteuse continue (9) qui fait monter le grain avant qu'il ne tombe sur une seconde transporteuse (7), une soufflante de prenettoyage (10) etant situee sous la transporteuse (9) pour souffler de l'air au travers des grains qui tombent sur la seconde transporteuse (7). L'air provenant de la soufflante de prenettoyage (10) est de preference dirige vers le grain prenettoye dans le mecanisme de separation du grain (5) et/ou au fur et a mesure qu'il tombe en passant au mecanisme de nettoyage du grain (8).
