Abstract
An agricultural vehicle including a chassis and a threshing system supported by the chassis. The threshing system includes a rotor, a front concave located at a distance radially away from the rotor and at least partially surrounding the rotor, and an infeed ramp connected to the front concave. The infeed ramp is located at a distance radially away from the rotor and has a plurality of slots therein. The threshing system also includes a support member positioned underneath the infeed ramp and a plurality of vanes connected to the support member. Each vane extends through a respective slot of the plurality of slots and is located at a distance radially away from the rotor. The vanes are configured for contacting and directing the crop material rearwardly towards the front concave.
Claims20
An agricultural vehicle, comprising:
- a chassis;
- and
- a threshing system supported by the chassis, configured for threshing a crop material, and including:
- a rotor;
- a front concave located at a distance radially away from the rotor and at least partially surrounding the rotor;
- an infeed ramp connected to the front concave, located at a distance radially away from the rotor, and said infeed ramp having a plurality of slots therein;
- a support member positioned underneath the infeed ramp;
- and
- a plurality of vanes connected to the support member and each said vane extending through a respective slot of said plurality of slots and being located at a distance radially away from the rotor, said plurality of vanes being configured for contacting and directing the crop material rearwardly towards the front concave.
A threshing system configured for threshing a crop material, comprising:
- a rotor;
- a front concave located at a distance radially away from the rotor and at least partially surrounding the rotor;
- an infeed ramp connected to the front concave, located at a distance radially away from the rotor, and said infeed ramp having a plurality of slots therein;
- a support member positioned underneath the infeed ramp;
- and
- a plurality of vanes connected to the support member and each said vane extending through a respective slot of said plurality of slots and being located at a distance radially away from the rotor, said plurality of vanes being configured for contacting and directing the crop material rearwardly towards the front concave.
A method of operating an agricultural vehicle, comprising the steps of:
- providing a threshing system for threshing a crop material, the threshing system including a rotor, a front concave located at a distance radially away from the rotor and at least partially surrounding the rotor, an infeed ramp connected to the front concave, located at a distance radially away from the rotor, and said infeed ramp having a plurality of slots therein, a support member positioned underneath the infeed ramp, and a plurality of vanes connected to the support member and each said vane extending through a respective slot of said plurality of slots and being located at a distance radially away from the rotor, said plurality of vanes being configured for contacting the crop material;
- directing a crop material flow by the infeed ramp toward the front concave;
- stopping the crop material flow, by said plurality of vanes, from spinning along a perimeter of the infeed ramp;
- and
- directing the crop material flow, by said plurality of vanes, rearwardly towards the front concave.
